DM2S/NX/LVI v1.0 (and ISE v10.2 etc.) -- merged checkpoint, 07/10/2026 21:29 AEDT

One file replacing four: Checkpoint_new3 (6-7 Oct, ISE v10 close-out), Checkpoint_carried_fwd (14:28), Checkpoint_new1 (20:30), Checkpoint_new2 (COB, stale-entries). Merged in that order; where two disagree the later one wins and the conflict is listed in section 2. Tags: PROVEN (Andrew's output / my test), CONFIRMED (Andrew saw it work), UNCONFIRMED (delivered, not reported installed).

1. Environment facts (all still hold)

Live: CentOS 6.10, python3 = 3.8.18 (no zoneinfo), server timezone +0800 (PHP Asia/Singapore), 3 hours behind Sydney. DB smf209, prefix smf209_. No credentials are recorded here or in memory.
Code: /var/www/html/The_ISE_Project. Data: /var/www/html/ISE_Data. Scripts live in /bin.
Attachments: /var/www/html/attachments and attachments2 (from smf209_settings.attachmentUploadDir), on-disk name {id_attach}_{file_hash}. Never search the disk by original file name.
ISE_Data/misc_store.json is 83 MB on one line: use Python s.find(), never backtracking grep.
Live shell aliases: cp -i, iptables (use \cp -a). Clone: rm is rm -i; glibc 2.12, only manylinux2010-or-older wheels; audio venv /root/venv-audio-test/bin/python (run cd / && ...AudioProcessor.py).
Live owns every store except audio_store.json (arrives via Clone push).
Media catalogue written by MediaIndexer; AudioProcessor reads media_store.json; MediaSearch builds from media_store.json + audio_store.json + captions_store.json.
[listatt]: routing in ListAttBBC::defaultSelectHref(), rows in buildHtml(), viewHref = Sources/view_attach.php?attach=N&topic=T, dlHref = index.php?action=dlattach;topic=T.0;attach=N. listatt 6.14 runs on SMF 2.0.x and 2.1.x, needs CollabCore (MsgTracker). Collaborative 5.0: Collabware to $boarddir, CollabCore to $sourcedir, via require-dir.

Conflicts between the checkpoints (resolve before installing anything)

A. Ranking zip vs MediaSearch. NameHitRanking carries MediaSearch 1.10.0; stale-entries carries 1.10.3 and is deployed. If 1.10.3 was built on 1.10.0 the name-hit code is already in; if not, installing the ranking zip would downgrade MediaSearch and lose --version/--help and the stale-entry skip. Same risk for search.py (ranking zip says no edit needed, so no clash expected). Rule: do NOT install NameHitRanking_v1.0.0 as is. Rebuild it as a new dotted version on top of what is on Live, once the Live versions/md5 are known.
B. AudioProcessor version. Checkpoint 1 says Andrew's is v1.2.3 and unchanged; new2 lists 1.2.3 with --prune/--version. Either the version was not bumped (breaks the delivery rule) or Andrew's earlier file was 1.2.2. Check the file on Live.
C. MediaIndexer. 9.9.7 is the last in the sealed list; new2 has 9.9.9. 9.9.8/9.9.9 are not described anywhere except --version. The hourly cron (7 * * * * ...MediaIndexer.py, wipe guard, flock, --force) is in 9.9.5-9.9.7; assume 9.9.9 keeps it, not shown.
D. flac/ogg/aac/wma. new3 says missing from the indexer filter (v9.9.4); cp1 says 9.9.7 adds them. Later wins: added.

3. Problem & Resolution (by topic)

3.1 Wildcard / file-name matching -- SearchCommon (new3)

Sensuous* found nothing: wildcard terms were anchored to the whole lowercased file name. Fix: shared SearchCommon.py; a term with */? matches the whole name OR any single word (split on spaces and [\W_]+, Unicode). Case-insensitive; plain term = substring; quoted phrases match whole name only; Misc stays case-sensitive (literal_cs=True); Media treats */? in quotes as plain text; empty name matches * in Misc/PDF, Media skips. PDFsearch keeps its own tokenise().
v1.1.0 PROVEN on Live (md5 of four modules). Package ISE_SearchCommon_v1.1.0.zip (1.0.0/1.0.1 superseded). md5: SearchCommon a31d54617669eddf7dc7412d20f4884b, MediaSearch 1.9.1 320ea8b0..., MiscSearch 7.7.1 6c3fdd4d..., PDFsearch 7.8.1 036a973b....
*.mp3 is a Media-only idea; wildcards in double-quoted phrases remain unsupported by design.

3.2 zoneinfo crash (new3)

Posts search showed "No results found for: methamphet*" because from zoneinfo import ZoneInfo (ResultFormatter line 77) fails on Python 3.8. Hotfix on Live: /bin/date +%z via subprocess (567 posts, exit 0, PROVEN). Backup ResultFormatter.py.bak_zoneinfo.
7.4.4 (md5 ebf7b03b...) has _os_timezone() with fixed UTC+8 fallback; display now follows the server OS timezone rather than fixed Singapore. Decision still Andrew's: follow server, or always Singapore. 7.4.5 (in the ranking zip) builds on 7.4.4.

3.3 `djjamestobin.m4a` (id 7189) not found (new3, then cp1)

Cause: MediaIndexer extension filter had no m4a. v9.9.4 added it (PROVEN, 2807 items). cp1 versions extended the filter to mp4 webm 3gp jpg jpeg png webp gif mp3 wav m4a flac ogg aac wma.
7189 is in the catalogue but has no audio features until AudioProcessor runs on it (timing Andrew's).
The web-root copy /var/www/html/djjamestobin.m4a is a separate public file (tidy-up).

3.4 MediaIndexer hourly run (cp1)

v9.9.5-9.9.7: atomic write (os.replace), flock lock (exit 3 busy / 4 lockfile), shrink guard MIN_KEEP_RATIO = 0.90 (exit 2, --force), MEDIAINDEXER_RUN ... summary line, [+] added ... listing. Suggested cron NOT installed: 7 * * * * /usr/bin/python3 /var/www/html/The_ISE_Project/MediaIndexer.py >> /var/log/MediaIndexer.log 2>&1. Superseded zips: v9.9.5 f1943862..., v9.9.6 895066f6...; v9.9.7 e1f5f63e... (file md5 faf1d5a6...).

3.5 Log flood (cp1) -- CONFIRMED

Bridges logged the full URL JSON (58 MB). ISE_Bridges_Logging_v1.0.0.zip (md5 5d64648d...): output written to qf_debug.txt only when no result page was produced, capped at 2000 chars. qf_debug.txt 376 bytes on Live; old logs deleted.
ise_trace.py v1.1.0 (md5 0828bf12...; zip e62ba798...) caps list/string/line/depth. UNCONFIRMED; ise_trace.log was 690057 bytes, re-measure after install.
The posts bridge passes --json explicitly; [] vs non-JSON output is how it tells zero results from a crash.

3.6 Name hits outrank everything -- ranking (cp1)

ISEpdf "Drug-related Sleep" ranked the PDF named exactly that 56th of 61. No rule looked at file names; LocationRule checks only result["subject"]; OccurrenceRule scores a name-only hit near zero.
Fix: ISE_NameHitRanking_v1.0.0.zip (md5 eb4acd9631287581800da9466e63d624): SearchCommon 1.2.0 (name_tier(), apply_name_priority(), 36 self-checks), RankingEngine 7.5.0 ("Name Hit" step, name_priority=False switch), ResultFormatter 7.4.5, ise_render 8.0#6 (ISEmega interlace), MediaSearch 1.10.0. All terms in the name: +2 x gap; some terms: +1 x gap; gap = max(1000, score spread + 1). Explicit /sort modes untouched.
Tested on mock data only. A partial-name hit also outranks body-only matches (by design).
PDFsearch applies --limit BEFORE ranking; a name-only PDF could be cut. Not changed.
Misc matches quoted phrases case-sensitively; the name tier is case-insensitive.

3.7 Stale entries and `--version` (new2) -- deployed, verified Clone/Live/Dev

Audio #7210 showed as "[No Subject]"/"No topic found": #7210 and #7214 were deleted from SMF (re-uploaded as #7222), but audio_store.json kept them. MediaSearch now skips and traces results whose attachment is gone; AudioProcessor reports stale entries and has --prune (no backup, by Andrew's call). Run on Clone: removed #7210, #7214 and 128 long-mix windows; store 71 items / 1627 windows; pushed to Live; Dev fixed.
--version/-V on seven modules, identical line <File>.py <version> (2026-10-07), handled before other imports; only the exact single argument is caught (the literal queries --version, -V, --help, -h can no longer be searched in MediaSearch; --version/-V in search.py).
Package ISEmedia_stale_entries_v1.0.4.zip (v1.0.0-1.0.3 superseded).
Ops done: LVM growth on Clone after the VMware disk expansion; passwordless SSH Clone <-> Dev; md5 compare of ISE_Data/*.json (Clone == Dev; Live ahead on post_store/word_index; the "second diff" failure was set -e vs diff exit 1, fix || true).

3.8 AudioProcessor on Clone (cp1)

System py38 had no transformers; the working CLAP environment is the venv. My mistake: I had Andrew install transformers 4.31.0/tokenizers 0.12.1 into system py38 and a fake safetensors-0.3.1.dist-info. Removal told, UNCONFIRMED: rm -rf the dist-info, optionally py38 -m pip uninstall -y transformers tokenizers.
--attachid N for one file; --features-only only touches items with missing/out-of-date measurements, --force redoes (not with changed sampling options); --verbose for the full report.
7231 transcript.wav measured (3m36s, 6 windows, -18.2 LUFS). 7235 long mix (~134 windows): full run UNCONFIRMED.
Speech to text: ISEmedia/AudioProcessor don't transcribe; dropped ("maybe one day", "forget it").

3.9 Smaller items

find_attachment v1.0.1 (md5 585155ac...): rows, disk check, store check. Its "is a key in this store" lines are noisy.
audio_features2_v1.0.0.zip, audio_features_list_v1.0.6.zip, AudioProcessor_v1.1.2.zip (not installed), Clone_audio_v1.0.0.zip, ISE_MediaProcessor_Parallel_v1.0.4.zip: delivered earlier; deployment not reported.
.video/3gpp (2 files): browsers can't play 3gp; "Failed to load media file" in the viewer; VLC plays it.
listatt_media_viewer.html CONFIRMED on Live (3906 bytes, rw-rw-rw-); ships in Collaborative (CollabCore).

4. Native / LVI design (nothing built)

Andrew's direction: (1) a "native" option for all multimedia in [listatt], like the PDF one; (2)(3) an LVI (Lightweight VLC Interface) BBCode driving VLC's HTTP interface, also called from [listatt].

Findings from Collaborative_v5.0.zip and listatt_bbcode_v6.14.zip:

The PDF [native] pattern exists in ListAttBBC.php v6.10, pointing at view_attach.php.
view_attach.php v1.8: board permission via {query_wanna_see_board}, multi-folder resolution, SMF 2.0/2.1, inline serving, whitelist pdf txt md log csv json html htm; no media types, no HTTP Range (206).
listatt_media_viewer.html v1.1 is a plain <audio>/<video>/<img> fed the dlattach URL; seeking through dlattach unverified.
defaultSelectHref() has no 3gp, so a 3gp row falls through to the ISE Text Viewer.
bufferFill (v6.13) re-renders on every page view, so anything minted at render time is fresh.
prep.sh: chmod 777 Sources/CollabCore; viewer 666. Flagged, not changed.

Proposed build (awaiting Andrew's go; timing his):

view_attach.php 1.9: media MIME types, 206 Range, same permission check.
ListAttBBC.php 6.15: [native] link on image/audio/video rows; unplayable formats (3gp, wma, avi, wmv, most mkv, mpg) get Download + Open in VLC; add 3gp etc. to the extension lists.
Collaborative 5.1: viewer message for unplayable formats; permissions (dir 755, files 644, apache).
LVI as its own mod (CollabCore dependency): signed link minted at render time view_attach.php?attach=N&exp=T&sig=HMAC, endpoint accepts a valid unexpired signature (VLC has no forum cookie), secret on Live, short expiry. LAN-only Clone alias not recommended.
FIRST, a throwaway browser-to-VLC test page. Unverified: VLC's HTTP interface needs a password and sends no CORS headers, so a cross-origin page can probably fire a play command but not read the reply; credentials may not attach. Fallback: an .m3u/.xspf the OS opens in VLC.

Hard rule: do NOT model new code on listatt (the v7.0 disaster). WRAP the working v6.14 code: the PDF [native] link is a four-line change in the row loop; do the same for media. Build on v6.14 and view_attach 1.8 as uploaded, change only what is listed, diff against them.

Baselines (uploaded zips): Collaborative_v5.0.zip 66ba89080d01f103ef953178bc3e0377 (viewer file d03bc883504f8049bfbe9f9e1c1c9246); listatt_bbcode_v6.14.zip 0035738843f003dd5d7abe402afb42ae (ListAttBBC.php ac05f2c3db379e97212e9442e31f1616, view_attach.php f1930429c14eb2d5319bffd18b343bb9). Both matched on 07/10 21:01.

5. Risk Analysis

Risk	Detail
Ranking zip vs deployed code (conflict A)	Installing as-is can downgrade MediaSearch 1.10.3. Rebuild on Live's versions as a new dotted version first.
Code coherence	The ranking/search files must match on Live, Clone, Dev (standing rule). SearchCommon stack + MediaIndexer 9.9.4 were verified on Live only before new2.
Name-hit ranking on mock data only	Test 3-4 real queries across posts / ISEpdf / ISEmisc / ISEmedia / ISEmega. Partial-name tier is strong; switch-off `name_priority=False`.
ResultFormatter	Live runs the sed hotfix with no fallback; 7.4.4+ follows server timezone. Decision open.
PDFsearch `--limit`	Applied before ranking; a name-only PDF could be cut.
`view_attach.php` Range	New code path on a security-sensitive endpoint (earlier permission hole fixed in v1.1). Needs a regression test: guest vs restricted board.
Signed links	Anyone with the link can read until expiry: short expiry, rate limit, secret only on Live, mint only for viewers who can see the post.
CollabCore 777 / viewer 666	Existing; fix proposed in Collaborative 5.1, not applied.
Browser to VLC may not work	Test page first.
`--prune` scope	Only entries absent from Clone's `media_store.json`. Run MediaIndexer first (done, 2816 items). Stale entries also sit in `captions_store.json` / `embeddings_store.json`.
MediaSearch skip uses the local DB	On Clone/Dev an attachment only on Live is skipped there too.
MediaIndexer hourly	Cron not installed. New uploads are not catalogued automatically until it is.
MediaProcessor (m4a etc.)	No frame/caption branch for audio: counted processed, nothing captioned. Not tested live.
Stray py38 installs on Clone	Harmless but misleading to pip. Removal unconfirmed.
No SMF code or files edited	Everything delivered is ISE Python; listatt/native work goes through the Package Manager.

6. Open items

Waiting on Andrew

Live versions/md5 of the files in conflict A-D so the ranking zip can be rebuilt (or declared already in).
Install/verify: NameHitRanking (rebuilt), MediaIndexer + optional cron, ise_trace 1.1.0.
Confirm cleanup of stray py38 installs on Clone.
7189 AudioProcessor run; 7235 full run; flac/ogg/aac/wma through AudioProcessor.
ResultFormatter timezone decision; install of 7.4.4+ replacing the sed hotfix.
"Go" on the native build, then the VLC test page; decision on CollabCore permissions (755/644).
Whether rebuild runs should list all added / removed items.
Clone/Dev coherence check after any ranking install.

Possible builds, none started

AudioProcessor: say why --features-only found nothing (not in store / already current); manual entry still v1.1.2; the end-of-run "not yet done" count treats stale entries as done until pruned.
PDFsearch rank-before---limit.
MegaSearch media source.
Stale-entry cleanup for captions_store.json / embeddings_store.json (MediaSearch skip covers display only).
--version for modules not touched yet: QueryParser, ANDMatcher, RankingEngine, audio_features, Collabware core_utils, etc. Start-up banners still differ per program.
Fuzzy search (the stated future work; ISE "basically complete bar fuzzy").

Backlog

Curvy.mp4 (6847) frame failure; Classification report v2.5; audio_store.json push Clone to Live (routine); AudioProcessor v1.1.2 install note.
OVERSEER holds: MiscIndexer.py stale fourth writer; IndexBuilder / orphan_check 7.4.3 delivered not deployed; COI daily check waits on all four writers.
Tidy-ups: public /var/www/html/djjamestobin.m4a; text/markdown stores possibly missing ids 7185-7199; forum page shows the audio-features report viewer twice (cosmetic).

7. Standing rules

Bump @version and @date in every changed module; manual version-history entry (the manual is a changelog, not prose); every executable shows its version once at start; deliver as a zip with a dotted, never-reused version (X_v1.0.2.zip), never loose files; xmllint --noout on any XML; list unrequested changes BEFORE building; end with a release-card table (done / not needed / missing).
Never rename his scripts or files. Critique before building. No SMF file edits outside the Package Manager. Deployment timing is Andrew's call: present options. PDF only, never Word. Markdown, not BBCode. Statements over questions; simple things simple (one-liners); no invented jargon.
Every reply starts with Claude: [DD/MM/YYYY--HH:MM:SS:mmm TZ] from running the Sydney-time snippet immediately before replying.
Never save credentials. Transcripts and checkpoints: never reuse a name; append _N.
Rules for the next session: don't search attachments by file name on disk; don't use slow grep on misc_store.json; read source before claiming what it does; don't suggest pip shims when he wants a non-Python route.

Checkpoint — Processing new media (Clone / Live / Dev)

Date: Monday 12 October 2026, written 11:21 AM Sydney Covers: the chat "Processing new media concurrently", 08:36 to 11:02 AM, 12/10/2026 Source: the 46-page PDF printed 11:13 AM. The chat itself has since been deleted, so this file and that PDF are the only record. Status when the chat closed: processing finished and pushed to Live; you had just said "going to mirror now". The mirror's outcome is not recorded here.

1. State at close

Item	State
Images/videos (MediaProcessor, ISE v9.27)	Run finished: "All 2 instances finished". Stores on Clone then held 2996 embeddings and 2993 captions
Audio (AudioProcessor v1.2.3, 2026-10-07)	87 of 87 items done, 1705 long-mix windows. New track is ID 7440
MediaIndexer	ISE v9.9.9 on both boxes. Clone catalogue is 2847 items after the deletions and the re-added track
Push to Live	Done about 10:58 with `json_push_audio_Clone_to_Live` and `json_push_visual_Clone_to_Live`
Dev	Behind Clone on the five processing stores (see section 5)
Mirror	You started it at 11:02. Result not seen

2. Decisions and standing facts established

Audio runs on Clone, never Live. Live's glibc 2.12 can't run torch, and Live is the production forum.
One MediaProcessor run only: py MediaProcessor.py --instances 2 --progress --log. Images and videos together, shared lock, cores split.
Never run two separate MediaProcessor invocations at once (e.g. --ft image in one window, --ft video in another). Both write embeddings_store.json.tmp, so one window's atomic replace takes the other's temp file and that one crashes. This happened at 09:13.
MediaProcessor is incremental by default. It skips anything with an embedding unless --force. --attachid N always runs as a single copy.
AudioProcessor has --plan (what's left and time estimate), --prune (drop stored entries whose attachment is gone; no backup made), --features-only. Don't run it alongside MediaProcessor.
tokenizers must never be installed on Clone. It is a compiled Rust package needing glibc 2.14; Clone has 2.12. transformers falls back to a pure-Python tokenizer when it's absent. Always install with pip install --no-deps transformers==4.31.0. A plain pip install transformers or -U pulls tokenizers in and breaks both processors.
No venv, system py38 only (your explicit instruction, 10:36).
Deleting an attachment: edit the post through SMF on the box, don't rm. Live and Clone each have their own SMF database, so it must be done on both (or re-synced from Live).
Attachment IDs are assigned per box. After re-uploading, compare ls -t /var/www/html/attachments2 | head -3 on Live and Clone. They matched (7440 on both).

3. Problems and resolutions

3.1 MediaProcessor died on import (08:46)

Problem: open_clip imports transformers, which loads tokenizers; the compiled library needs glibc 2.14. This came from the earlier transformers/tokenizers install in system py38.
Resolution: pip uninstall -y transformers tokenizers, remove the fake safetensors-0.3.1.dist-info, import test open_clip. MediaProcessor then ran.
Risk: this broke AudioProcessor later (see 3.5).

3.2 CLIP weights "No such file" after a full download (08:55)

Problem: the 605MB blob finished but the snapshot link was missing at the moment of the check.
Cause: two processes first-time downloading the same model into /root/.cache/huggingface. Confirmed at 09:11: blob and link both present, stamped 08:55.
Resolution: loaded once alone with py MediaProcessor.py --attachid 6847; weights now cached.
Watch: /root was 92% used with 5.2GB free.

3.3 Temp-file crash with two windows (09:13)

See section 2. The store on disk was safe (atomic write); the loser's recent items would have been redone by the next incremental run.

3.4 Bad files removed

Curvy.mp4, ID 6847: ffprobe said 970s, ffmpeg wrote no frame at 7.5s. Deleted through Live's SMF, then Clone's.
7326, 7336, 7350 (KLF "3 A.M. Eternal"): ffprobe "Invalid data". On Clone, 7326 was a 2-byte ASCII stub; 7336 and 7350 were gzip data, both exactly 127,200,115 bytes with the same internal timestamp. The contents were never inspected (the zcat check was offered, not run). Deleted on Live and Clone.
7331 (the working copy of the same track) was deleted along with them (same filename, probably the same post).
Fix: re-uploaded on Live and Clone as 7440. Clone: MediaIndexer, AudioProcessor --prune (removed stale 7331), then encoded 7440 (6 windows, 44s, 119.5–120 BPM, A# minor, −14.4 LUFS).

3.5 AudioProcessor failed: "No module named transformers" (10:26)

Cause: 3.1 removed transformers from system py38. AudioProcessor's CLAP encoder needs it.
My errors: I guessed /root/venv-audio-test was the working environment (it wasn't), then proposed a new venv, which you rejected.
Resolution: py -m pip install --no-deps transformers==4.31.0. AudioProcessor then ran: CLAP laion/clap-htsat-unfused loaded in 42.1s, log says "tokenizers (Rust) not available — using the pure-Python RoBERTa tokenizer". resume_download and "special tokens" warnings are harmless.
Not confirmed: py -c "import open_clip; print('ok')" after this reinstall was suggested but its result never came back. Run it before the next MediaProcessor run.

3.6 Embedded but uncaptioned: 3 items

735 gave up after 3 caption attempts. Reason is in /var/www/html/ISE_Data/caption_failures.json. One retry: py MediaProcessor.py --attachid 735 --max-caption-retries 0. Not yet done as far as the transcript shows.
110_t15, 110_t22: source frames no longer exist. They stay caption-less with their embeddings kept. Harmless.

4. Code and file changes

Change	Where	Status
`pip uninstall transformers tokenizers`, then `pip install --no-deps transformers==4.31.0`	Clone, system py38	Done
Removed fake `safetensors-0.3.1.dist-info`	Clone, `/usr/local/lib/python3.8/site-packages`	Command given; you reported it working
`rm -f /var/www/html/ISE_Data/processor_checkpoint*.json`	Clone	Command given at 10:56 after you said to get rid of them. Not confirmed run. MediaProcessor decides skips from stored embeddings, and `json_push_visual_Clone_to_Live` skips the checkpoint if absent. Both from help text and your scripts, not from reading MediaProcessor.py

cleanISE_Clone rules (dry run by default, acts only with --apply; anything not listed is untouched):

*.tmp older than 60 minutes deleted.
*.log over 2MB rotated to .log.1, then .log.2, original emptied. Only misc_indexer.log (4.3MB) qualifies today.
processor_checkpoint_i*of*.json older than a day deleted.

Risk: log rotation is copy-then-empty, so a line written in that instant can be lost. Every *_store.json, word_index*.json, chain_snapshot.json, orphan_state.json, caption_failures.json, audio_checkpoint.json and processor_checkpoint.json itself are left alone.

Release card (as delivered): version/date done (1.0.0, 2026-10-12); manual history done; version shown at start done; dotted zip name done; xmllint not needed; unrequested changes listed beforehand done; legacy zipper not needed (not an SMF package).

5. Diff results after the push (10:58)

Live vs Clone: identical on the five processing stores (audio_checkpoint, audio_store, captions_store, embeddings_store, media_store). Different on six Live-owned indexes (misc_store, pdf_store, post_store, word_index, word_index_misc, word_index_pdf). Live's are newer, so Clone's copies are older, which is expected.
Clone vs Dev: Dev matches Clone on those same six, so it is equally behind Live. Dev differs from Clone on the five processing stores, so it is behind today's work.
word_index_media.json matches on all three boxes.

6. Open items and cautions for the mirror

Mirror direction. Live's six indexes are newer than Clone's. Any mirror step that writes Clone's ISE_Data to Live would overwrite them with older copies. Only the two push scripts should write the five processing stores.
--delete on mirrorISE_*. Whichever box is the destination loses files that exist only there (processor_checkpoint*.json, pdf_dupe*). Check that matches what you want.
dbbacksmf, dbbacksm2, SQLhousekeeping: if not already pulled from Live into Clone's /bin, the mirror would push Clone's older copies over Live's fixed ones. Not confirmed either way.
mirror1_Clone -n has never been dry-run.
After the mirror, re-run the three json_diff_md5sums checks.
Dev needs the five processing stores to meet your three-box coherence rule. Timing is yours.
Run py -c "import open_clip; print('ok')" on Clone before the next MediaProcessor run (see 3.5).
Item 735's caption failure: read caption_failures.json, decide whether to retry.
/root on Clone is 92% used (5.2GB free).
Catalogue arithmetic, unexplained: Clone's media_store fell from 2853 to 2846 items between the 10:12 and 10:25 indexer runs, with 4 of those being audio (90 to 86). Deliberate deletions were 5 in total (6847, 7326, 7336, 7350, 7331), so 2 non-audio items beyond the expected ones went missing from Clone's catalogue. It may be nothing (e.g. other items on the same posts), but it was not checked. Live's media_store matches Clone's, so both agree.
word_index_media.json: orphan (no .php, .py or .sh under the web root names it), only 127K. Deleting it means touching all three boxes, and json_diff_md5sums_All_Clone would report it missing until Live and Dev lose it too. Left in place.
json_push_media_Clone_to_Live: old duplicate of json_push_visual_Clone_to_Live (same v1.0.2 block), still on your removal list, not removed.
The rw-rw-rw- files and logs: chmod on Clone alone would likely be undone by the next mirror; the fix belongs at the source. Not urgent.
Empty logs (indeximages.log, mediawatchdog.log, orphan_check.log) are 0 bytes from Oct 7. Harmless.

1. Standing rules (operator = Andrew, forum username "Chip")

Every SMF package zip must be built with his legacy zipper, never a plain or streaming zip (PclZip rejects data-descriptor zips). Claude has no copy of that tool; it matches a working zip's properties (flag 0x0, plain deflate, no extras) and he re-zips. Release card carries a "legacy zipper used" line.
Delivery rules: bump @version/@date, manual version-history entry, every executable prints its version once at start, dotted never-reused zip version, xmllint --noout on XML, list unrequested changes BEFORE making them, release card table.
No manual edits to SMF files, ever. Package Manager only.
Never rename his scripts or files. Never reuse an old name for an updated file; append a number.
Claude owns LVIBBC.php; he will not review it. Claude maintains it. A loud error is better than guessing. "Do not hurry."
Reply header, casual mode: Claude: [Month DD, YYYY, HH:MM:SS AM/PM], time from an executed command each reply. Do not mimic his tone. Fewer questions, no jargon coined by Claude, no bloat.
Audio/video indexing runs only on Clone. Never on Live or Dev.

2. LVI (Lightweight VLC Interface) — DONE

[lvi] SMF 2.0.x BBCode mod, v1.0.1 (2026-10-07), package id AEgerszegi_with_Claude_ai:LVI-bbcode. Built on LMV 4.5.1 plumbing; autodisplay, scrolling and Markdown deliberately excluded.
Tag forms: [lvi]URL[/lvi] (http/https), [lvi=ID], [lvi=0]/00 (first media attachment on the post), [lvi=attach-NN] (Nth media attachment, 0-indexed).
Panel: Open in VLC (.m3u), VLC remote play/add (requests/status.xml?command=in_play|in_enqueue), Copy URL, change VLC address (localStorage lvi_vlc_addr, default 127.0.0.1:8080).
Hooks: integrate_bbc_codes, integrate_bbc_buttons, integrate_pre_include; registered by LVI_register.php, removed by LVI_unregister.php. Needs CollabCore 2.0+ (requireOrDie takes three args).
Delivered out/LVI_v1.0.1.zip (md5 1cc5854f0ec02bd5d9074b38ed638ecf). Andrew's LVI_v2.0.zip has identical code files plus his extras.
Confirmed working by Andrew on a real SMF 2.0.x test system: install, tag forms, toolbar, .m3u, VLC remote buttons.
Not proven: playing an attachment from a restricted board (VLC sends no forum cookie).
His v2.0 housekeeping: package-info references readme.md but his file is README.md.md; lvi.css.css is unused MD-mod CSS; LMV's lvi.gif/lvi.png are leftovers; a stale first merged checkpoint sits in the zip. His TODO: VLC-viewer CSS, maybe merge CSS into LVIBBC, a VLC-style editor icon (not VLC's cone logo), document SMF 2.1 data-between-tags requirement.

3. Parked (nothing requested)

SMF 2.1.x support for LVI — declined "not now".
RedBox dynamic error handler integration (lazy-load with plain fallback; RedBox is a separate mod, topic 7681).
Signed links for restricted-board attachments.
Original VLC-flavoured icon; readme filename fix.
Folding the "Processing new media" checkpoint (Checkpoint_ProcessingNewMedia_20261012_1121.md) into a later merged checkpoint; it was acknowledged only.

4. Open item at the end of this chat

cleanISE_Clone 1.0.0 (2026-10-12), run on Clone as sh cleanISE_Clone, failed: line 71: syntax error near unexpected token '<' at done < <(find "$DIR" -maxdepth 1 -type f -name '*.tmp' -mmin +"$TMP_MIN" -print0).
Cause: on CentOS 6, sh is bash in POSIX mode, which disables process substitution. Running it with bash cleanISE_Clone (or ./cleanISE_Clone with a bash shebang) avoids it.
Fix only if he wants sh to work: rewrite that loop without process substitution, as a new script version. Not requested yet. Claude has not seen the script in this chat.

5. Carried ISE facts (from earlier checkpoints, unchanged)

Three boxes: Live (CentOS 6.10 64-bit, production, no torch), Clone (py38, glibc 2.12, runs all audio/video indexing), Dev (32-bit, rebuild to 64-bit planned).
On Clone: never install tokenizers; pip install --no-deps transformers==4.31.0. Transformers 4.31.0 must stay; only tokenizers and fake safetensors dist-info get removed. (The earlier advice to uninstall transformers was wrong.)
Attachment ids are per box. Take care with mirror/overwrite scripts. Deployment timing is his call.
Test system for mods: fresh SMF with only Collaborative 5.0 (Collabware + CollabCore + bin scripts + data store).

cleanISE_Clone -- manual

Version: 1.0.4 (2026-10-16) Runs on: Clone, as root. Lives in /bin (Clone's /bin is the master). Author: Another collaboration between Andrew.human and Claude.ai

Purpose

Keeps /var/www/html/ISE_Data free of leftovers, so it can be run often. It is deliberately small: it matches five kinds of file and nothing else.

Usage

cleanISE_Clone                      # dry run: prints what it would do, changes nothing
cleanISE_Clone --apply              # does it
cleanISE_Clone --version            # prints the version and exits
cleanISE_Clone -h                   # prints the usage and exit-code lines

--all-checkpoints (the v1.0.1 option) is still accepted, so older command lines keep working, but it does nothing: since v1.0.3 that behaviour is the default.

Run it with bash cleanISE_Clone or directly (./cleanISE_Clone, /bin/cleanISE_Clone), never with sh. On CentOS 6 sh is bash in POSIX mode, which refuses the done < <(find ...) loops: syntax error near unexpected token '<'.

The version line is printed once, at the start of every run.

Exit codes: 0 ok, 1 ISE_Data missing or an action failed, 2 bad argument, 3 the old-named checkpoint files were left alone because something is running (the other rules still ran).

Rules

Only files directly inside ISE_Data are looked at (no subdirectories).

#	Matches	Condition	Action
1	`*.tmp`	older than `TMP_MIN` (60 min)	deleted
2	`*.log`	bigger than `LOG_MAX_KB` (2048 KB)	copied to `<name>.log.1` (old `.1` becomes `.2`, old `.2` overwritten), then the original is emptied in place
3a	`processor_checkpoint.json` and `processor_checkpoint_iof.json` (the names MediaProcessor used before v9.30)	nothing is running: any age. Something is running: only the `_iof` ones, and only if older than `CKPT_MIN` (1440 min = 1 day)	deleted
3b	`processor_checkpoint_iof.ckpt` (current per-instance names, MediaProcessor v9.30 and later)	older than `CKPT_MIN` (1440 min = 1 day)	deleted
4	`audio_store.json.pre*` (hand-made restore copies, e.g. `audio_store.json.pre2419`)	older than `PRE_MIN` (10080 min = 7 days)	deleted
5	`audio_store.json.lock`	older than `PIDLOCK_MIN` (60 min) and the process id written in it (`pid N, started ...`) no longer exists	deleted

The five values (TMP_MIN, LOG_MAX_KB, CKPT_MIN, PRE_MIN, PIDLOCK_MIN) and the two paths (DIR = /var/www/html/ISE_Data, PROJ = /var/www/html/The_ISE_Project) are variables at the top of the script.

Rule 5 prints left alone instead when the file has no pid N, in it, or when process N still exists.

"Nothing running"

Only rule 3a depends on it. The script counts something as running if any of these is true:

a process named python*, py, ffmpeg, ffprobe or llama-mtmd-cli whose working directory is PROJ, or whose command line contains PROJ or DIR, or that has a file open under DIR;
one of these lock files is held (tested with flock -n): .mediaprocessor.lock, .mediawatchdog.lock, audio_store.json.lock (all in ISE_Data) and MediaIndexer.lock (in $TMPDIR, else /tmp);
flock is not installed (the locks cannot be checked, so it is treated as busy).

When any of them is found, the script prints what it found, leaves the checkpoint files rule 3a would have removed, still runs every other rule, and exits 3. A plain shell script that holds none of those locks is not detected.

Checkpoint file names

MediaProcessor v9.30 writes processor_checkpoint.ckpt and processor_checkpoint_i<k>of<N>.ckpt (still JSON inside). The .ckpt names are deliberately not matched by the .json rule, so the last run's checkpoint survives cleanup. Old-named .json files already in ISE_Data are removed by rule 3a when nothing is running. Anything outside MediaProcessor that reads processor_checkpoint.json must be changed to the new name.

Never touched

No rule matches any of these, so they are never removed or changed: *_store.json, word_index*.json, processor_checkpoint.ckpt, audio_checkpoint.json, caption_failures.json, chain_snapshot.json, orphan_state.json, pdf_duplicates.json, pdf_dupe_deleted.json, and the lock files .mediaprocessor.lock and .mediawatchdog.lock.

Deliberately not included

word_index_media.json: no .php, .py or .sh under the web root names it, but the md5 comparison scripts do not exclude it, so removing it means removing it from Live, Clone and Dev together. Do that by hand if wanted.
Permissions (rw-rw-rw- on some files): set by whatever creates the files and carried by the mirrors. Fix at the source, not here.
.mediaprocessor.lock, .mediawatchdog.lock: empty files that programs lock with flock. The lock belongs to the open file, not to the name, and the OS drops it when the program ends, so they cannot go stale. Deleting one while it is held lets a second program lock a new file of the same name, and both then think they hold the lock.

Cron (suggested, not installed)

23 * * * * /bin/cleanISE_Clone --apply >> /var/log/cleanISE_Clone.log 2>&1

Each run writes a few lines, so that log grows slowly. Check it now and then. The cron line needs --apply; without it every run is a dry run. An exit code of 3 in that log only means a job was running at that moment and the old-named checkpoints were left until the next run.

Notes

Log rotation is copy-then-empty, not rename, so a program with the log open in append mode keeps working. A line written between the copy and the empty can be lost.
-mmin uses the file's modification time, so a checkpoint or .tmp being written right now is never old enough to match.
Rule 5 has one small gap: if the audio job also holds a real flock on audio_store.json.lock and a new job starts in the instant between the script's check and its delete, two jobs could run at once. The age and process checks make that very unlikely.
The checkpoint files are only a progress log. MediaProcessor resumes from embeddings_store.json, so deleting a checkpoint loses no work.

Version history

Version	Date	Change
1.0.0	2026-10-12	First release: stale `.tmp` removal, size-capped `.log` rotation, old per-instance processor checkpoint removal. Dry run by default.
1.0.1	2026-10-16	Added `--all-checkpoints`: also removes `processor_checkpoint.json` and every per-instance checkpoint regardless of age, but only when nothing is running (exit 3 if something is). Arguments can be combined (`--apply --all-checkpoints`).
1.0.2	2026-10-16	Rule 4: `audio_store.json.pre*` older than 7 days is removed.
1.0.3	2026-10-16	Removing the old-named checkpoints when nothing is running is now the default (`--all-checkpoints` still accepted, does nothing). Goes with MediaProcessor v9.30 (`.ckpt` names): old `.json` names removed when idle, `.ckpt` names kept (per-instance ones once older than `CKPT_MIN`).
1.0.4	2026-10-16	Rule 5: a stale `audio_store.json.lock` (pid gone, older than 60 minutes) is removed.

📝 #do-not-index.mdTheme:

Claude

17 October 2026 (Sydney time)

Rule: An attachment is skipped when its parent post's body contains #do-not-index, case-insensitive. Only the post body is checked, not the subject.
Lookup: The standard SMF join does it (attachment to its post via id_msg, then the body text). One helper function answers "is this attachment excluded?", and every indexer calls it before processing a file.
Purge: Skipping at index time isn't enough. If the tag is added after a file was indexed, the file stays searchable. Each indexer needs a purge pass that removes entries for any attachment whose post now carries the tag.
Tag removed later: The attachments become indexable again on the next run, which seems the right behaviour.
Gap: The post text itself is still indexed by SMF's own search and by ISE's post index. The tag protects attachments only, as you specified. To hide the text too, it would need a second rule in the post indexer.

To build it, send:

Every indexer that reads attachments: PDFIndexer.py, the Misc indexer and MediaIndexer.
Whatever module handles their database connection and config.

I'll add it as one shared helper plus a call at the top of each indexer's file loop. The delivery will be a versioned zip with the release card, and it will include the purge pass.

I can zip with password too

Claude: [October 17, 2026, 05:03:23 PM]

A password on the code zip isn't needed. If you do use one, put the password in the chat message, because I can't open an encrypted archive otherwise. The indexer code isn't sensitive. The only thing to watch is that the config or database module may hold credentials, so blank those lines out before sending. I only need to see how the connection is made, not the actual password.

For the private material, a password-protected zip is a better fit than a plain PDF on the forum. Indexers can't read inside an encrypted archive, so it sidesteps indexing by design, and the contents stay protected even if someone fetches the attachment URL directly. Use AES-256 encryption (the legacy ZipCrypto scheme is weak), and use a long passphrase that you keep off the forum.

The #do-not-index rule is still worth building. It covers all the unencrypted attachments you may want hidden later, and the encrypted zip can be the extra layer for this particular material.

zip -e ?

Claude: [October 17, 2026, 05:05:24 PM]

zip -e works, but it uses the old ZipCrypto scheme, which is weak, so it won't do for this material. Use 7-Zip for AES-256:

7z a -t7z -mhe=on -p private.7z file1.pdf file2.pdf

-p with nothing after it: It prompts for the password, so it stays out of your shell history.
-mhe=on: It encrypts the filenames as well as the contents, so the archive doesn't reveal what's inside.
If you need .zip: Use 7z a -tzip -mem=AES256 -p private.zip file1.pdf. This hides the contents, but the filenames stay visible.

The p7zip package provides 7z on your Linux boxes.

[MediaIndexer.py] [PDFIndexer.py] [MiscIndexer.py] [AudioProcessor.py] [IndexBuilder.py] audio, visual, post, pdf and misc -- all apply

this is a smart addition to ISE !

even if the indexers operate in "single" mode

Claude: [October 17, 2026, 05:16:01 PM]

Single mode is covered. I'm applying the rule in every mode, and the unrequested changes are listed first so you can stop me before I touch anything.

Single mode: MediaIndexer --single, PDFIndexer --single and AudioProcessor --attachid all honour the rule. A marked attachment is not indexed, and any entry it already has is removed. MiscIndexer and IndexBuilder have no single mode; they rebuild fully each run.

Changes you didn't ask for (nothing else will change):

New file ise_noindex.py holding the rule once. All five indexers call it.
Fail closed. If the marked-post list can't be read from SMF, the run stops and writes nothing, instead of indexing everything.
Thumbnail records of marked images are excluded too.
Purge of existing entries. PDFIndexer removes already-indexed PDFs from marked posts. AudioProcessor removes their stored items at the start of every run, so no --prune is needed.
IndexBuilder: the post counts in its summary now mean posts indexed, with the skipped count shown beside it.
Version, date and history bumps in all six files.

Gap: MediaProcessor.py and MediaSearch.py weren't in the upload. Frame captions and vectors already made for newly marked images or videos will stay in their store until MediaProcessor gets the same purge.

to confirm, this is all predicated on the post containing the string somewhere on lines 1-5

Confirmed, and I fixed it. My first version matched the tag anywhere in the post body. It now only counts if #do-not-index is on lines 1–5. A tag on line 6 or later is ignored. Matching is still case-insensitive, and the subject line is never checked.

SMF stores line breaks as  , so the line count treats  ,  ,   and plain newlines all as line breaks.

I ran a test harness against all six files. It uses stand-in databases and PDFs, not your live SMF board or real attachments. It all passed, including these cases:

Line boundary: the tag on line 5 is honoured and the tag on line 6 is not.
Thumbnails: each marked image's thumbnail record is excluded along with the image.
Single mode: MediaIndexer, PDFIndexer and AudioProcessor each remove a marked item that is already indexed, even when run in --single mode.
Database failure: every indexer stops without writing anything if the exclusion lookup fails.

Put the tag in the first five lines of the Master post. If it sits lower, the post and its attachments get indexed. Since a lower tag fails open, I'd keep the tag on line 1.

Deployment: ise_noindex.py has to sit in the same folder as the indexers.
Audio: AudioProcessor runs on the Clone, so push audio_store.json to Live afterwards. Otherwise Live keeps the old entries.
Not covered: I never received MediaProcessor.py or MediaSearch.py. Frame captions already generated for a newly marked image or video stay in place until MediaProcessor.py gets the same purge. Send it and I'll add it.
Still reachable: direct attachment URLs and SMF's own search of post text are unaffected. Encrypting the zip you attach is still your best protection.

oh, ADMIN ONLY

Claude: [October 17, 2026, 05:20:50 PM]

Keep the tag on line 1 even with the post admin-only. The two protect different things:

Admin-only board or post: SMF itself enforces this on viewing and on its own search, so non-admins can't open the post or find it there.
The ISE indexers: they read the database directly, so they ignore SMF permissions. Without the tag they would index the post and its attachments. Whether ISE search results then check the viewer's permissions is something I can't see from the five indexers I have. If they don't, the content could show up in results for non-admins.

The tag is what closes that gap, so use both.

Direct attachment URLs aren't covered by either. A non-admin who has the exact link to an attachment may still be able to download it. If that matters, password-protect the zip as well.

or Moderator, to be safe

Claude: [October 17, 2026, 05:21:26 PM]

Admin or Moderator is fine for the post's visibility. One thing needs checking first.

A global moderator can see every board. A board-level moderator can only see the boards they moderate. So if the Master post is in an admin-only board, board moderators won't see it, but global moderators will. If you want moderators locked out too, restrict the post to Admin only. If you want them in, put it in a board they moderate.

The #do-not-index tag doesn't depend on any of this. It applies to the post whoever can view it.

no, only Moderator and above can exclude posts+their att's from indexing !

Claude: [October 17, 2026, 05:23:33 PM]

Done. #do-not-index now only works when the post's author is a Moderator or above. It still has to sit on lines 1–5. A tag in a regular member's post, or a guest's, is ignored and the post is indexed as normal.

"Moderator or above" is my reading of your rule, so check it. An author counts if they are in:

group 1 (Administrator), as primary or additional group;
group 2 (Global Moderator), as primary or additional group;
or they moderate that post's own board, so a board moderator's tag works only in their own board.

Groups 1 and 2 are SMF's default ids and are constants at the top of ise_noindex.py. If your forum uses different ids, change them there. If you don't want board moderators included, I'll drop that clause.

The check is on the post's author, not on whoever typed the tag. SMF doesn't record who edited a post's text. So if a moderator adds the tag to a member's post, it is ignored, and the moderator has to write the post themselves. Your Master post is fine, since you wrote it.

I tested this against stand-in databases, not your live board. The tests cover admin, global moderator, additional-group moderator, board moderator, regular member, guest and a moderator of a different board, all passing.

[ISE_Python_Scripts_Manual.md] ... and in the manual she goes too !

Claude: [October 17, 2026, 05:24:25 PM]

The manual is updated to Master v6, with a new #do-not-index section. It covers the three conditions (tag in the body, on lines 1–5, author Moderator or above), what each indexer does, and the known gaps. I also added notes to the PDFIndexer, MiscIndexer, MediaIndexer and shared-dependency sections, and a v6 history entry. The file keeps its original name.

Don't deploy the MiscIndexer.py from either zip. The manual shows MiscIndexer at v7.5.0 with --single, but the copy I patched was 7.4.1#3, which doesn't have it. Installing mine would have dropped --single. ISE_DoNotIndex_v1.2.0.zip contains that stale copy, so use ISE_DoNotIndex_v1.2.1.zip, which leaves MiscIndexer.py out. Send me your current 7.5.0 and I'll add the rule, including how --single handles a marked attachment. The manual lists MiscIndexer as pending until then.

The v1.2.1 zip holds the other four indexers plus ise_noindex.py, with no code changes from v1.2.0. Everything else in the zip is as tested earlier.

I have my own, owner's board and the admins are not the full quid and cant see my stuff !

Claude: [October 17, 2026, 05:25:50 PM]

A board only you can see keeps the other admins out of the board itself, but not out of the indexes. The indexers read the database directly and ignore board permissions, so the tag is still what keeps the post and its attachments out of ISE. I can't confirm whether ISE's search results check board permissions, because I haven't seen the search scripts. If they don't, the tag is the only thing standing between those admins and your material.

One thing could make the tag fail without any warning. The rule honours it only if the post's author is in group 1 (Administrator) or group 2 (Global Moderator), or moderates that board. If the account you post from is the forum's owner account in group 1, you're fine. If it's a separate or custom group, the tag is silently ignored and the post gets indexed. In that case, add the account as a moderator of your board, or add its group id to PRIVILEGED_GROUPS at the top of ise_noindex.py.

Check before you rely on this: after the first run of each indexer, search ISE for a word that only appears in the Master post, as an account that can't see your board. It should return nothing.

yes but my Group 1 does not have full Admin rights -- but yeah, i will test it for sure. Time to login from the NUC as this is a very welcome mod !

Claude: [October 17, 2026, 05:28:27 PM]

Group 1 having reduced rights doesn't matter here. The rule looks only at group membership by id, not at what the group is allowed to do. As long as your account is in group 1, the tag is honoured.

Send over your current MiscIndexer.py (the 7.5.0 one) when you're back, and I'll bring it in line with the others. Until then, the four indexers in ISE_DoNotIndex_v1.2.1.zip cover posts, PDFs, media and audio. Misc attachments (.md, .txt, .json and so on) are still indexed regardless of the tag.

I sent u all of them b4, didn't I?

Claude: [October 17, 2026, 05:29:17 PM]

You did send all five, and I worked from exactly what you sent. The mismatch is between two of your own files.

The MiscIndexer.py you uploaded is v7.4.1#3, dated 2026-10-05, and has no --single.
The manual says MiscIndexer got --single in v7.5.0 on 2026-10-01. The v7.4.1#3 file is dated after that but carries an older version number, so one of the two is out of step.

The uploaded PDFIndexer.py (8.6.1) and MediaIndexer.py match what the manual says, so those two are fine.

I can't tell from here which copy is current. To find out, run this on whichever box holds your working copy:

grep -n '^@version' MiscIndexer.py; grep -c -- '--single' MiscIndexer.py

If it shows 7.4.1#3 with a count of 0, the manual is wrong about 7.5.0. I'll ship the Misc build I already made and correct the manual.
If it shows 7.5.0, send me that file and I'll patch it. Single mode will also drop a marked attachment from the Misc index.

my latest is 7.4.1#3

Claude: [October 17, 2026, 05:30:30 PM]

Then the Misc build is the right one, and ISE_DoNotIndex_v1.2.2.zip now has all six files. MiscIndexer.py is back in as 7.4.1#4, with no code changes since the v1.2.0 tests.

The manual was wrong, not your script. It describes a MiscIndexer v7.5.0 with --single, and your latest has no such flag. I left that old text in place and added a note in the MiscIndexer section saying --single isn't in the current script. The v6 history entry records the correction. The corrected manual is attached. You may want to correct the 2026-10-01 history entry yourself.

Use v1.2.2 and ignore v1.2.0 and v1.2.1. The code is the same as v1.2.1, and v1.2.2 just adds MiscIndexer.py back.

where are u getting 7.5.1 from ?

Claude: [October 17, 2026, 05:30:49 PM]

I haven't used 7.5.1 for any indexer. The MiscIndexer numbers I've used are:

7.5.0: from your manual, which turned out to be wrong.
7.4.1#3: your actual latest.
7.4.1#4: my patched build, in the v1.2.2 zip.

The only "7.5.1" anywhere in the manual or the scripts is about the search scripts, not the indexer. It's in the MegaSearch section: "Same fix as PDFsearch.py v7.5.1 and MiscSearch.py v7.5.1". It may be what you're thinking of.

what abouit the 4 indexers ?

Claude: [October 17, 2026, 05:36:44 PM]

I read your question as asking about the indexers' versions, so here is each one, before and after. There are five indexers in the zip, plus the shared helper. None of them is on 7.5.1.

Script	You sent	In `ISE_DoNotIndex_v1.2.2.zip`
`IndexBuilder.py`	7.4.4	7.4.5
`PDFIndexer.py`	8.6.1	8.7.0
`MiscIndexer.py`	7.4.1#3	7.4.1#4
`MediaIndexer.py`	ISE v9.9.9	ISE v9.9.10
`AudioProcessor.py`	1.2.3	1.3.0
`ise_noindex.py` (new)	n/a	1.2.0

The one real difference between the indexers is that MiscIndexer.py has no --single. That is why it only takes the tag on full runs.

If you meant something else by "the 4 indexers", for example the four I named when I withheld Misc, tell me which and I'll answer that instead.

oh, they are zipped

Claude: [October 17, 2026, 05:37:34 PM]

Yes, all six files are in ISE_DoNotIndex_v1.2.2.zip, flat, with no folder inside. Unzip it into the folder that holds your indexers. ise_noindex.py has to sit beside them.

all 7 files are in - now gonna check the ISE Data to see if any indexers slipped by ...

Claude: [October 17, 2026, 05:42:08 PM]

The zip holds six files, so I take your seventh to be the manual. If you counted something else, check it.

For the check, take the id_attach of one of the Master post's attachments and look for it in each store. The stores are keyed by id, so grep -c '"123456"' against pdf_store.json, misc_store.json, media_store.json and audio_store.json will do. Post text is a different test: a word that appears only in the Master post, searched against post_store.json.

Two things to expect:

Nothing happens until each indexer has run. IndexBuilder, MiscIndexer and MediaIndexer (plain run) drop a marked post or attachment when they rebuild. PDFIndexer and AudioProcessor purge old entries at the start of their next run.
A few places will still hold the old data:
- Live's copy of audio_store.json until you push it again.
- Captions or embeddings MediaProcessor already produced for a marked image or video.
- Any backups.

yes !

Claude: [October 17, 2026, 05:43:08 PM]

Good. If any store still holds the Master post after its indexer has run, send me the indexer's output and the store entry. The usual cause is the author's group id, which I covered earlier. I'll also add the same purge to MediaProcessor.py whenever you send it.

i might push them up from clone and wipe them out

Claude: [October 17, 2026, 05:43:37 PM]

Pushing the Clone's stores to Live would remove the old entries there, as long as the Clone's copies are clean first.

Order: run the indexers on the Clone and confirm the Master post is gone from each store there. Then push, so Live ends up with the clean copies.
Live's MediaProcessor output: pushing the stores won't clear captions or embeddings for a marked image or video that were already generated. Those live in captions_store.json and embeddings_store.json, which only MediaProcessor.py builds. Check whether those are among the files you push.
Backups: old copies of the stores on Live or elsewhere keep the entries until they age out or you delete them.

Claude: [October 17, 2026, 05:43:56 PM]

Your prompt says 14:42 on Live while your clock says 17:42, so Live is three hours behind you. Read that way, only one store has been rebuilt since I delivered the zip:

misc_store.json and word_index_misc.json (14:31): that is 17:31 your time, a minute after the v1.2.2 zip arrived, so this was probably the new MiscIndexer.
post_store.json and word_index.json (14:00): that is 17:00 your time, before any of my zips, so this was the old IndexBuilder.
media_store.json (14:07): also before the zip, so the old MediaIndexer.

Those two will still hold the Master post until you rerun them. Your listing also shows no PDF or audio stores. If that was just a filtered view, they aren't affected here.

To confirm the new code actually ran, check the logs:

Misc: grep -i 'do-not-index' misc_indexer.log should show a line like #do-not-index: N attachment(s).
Posts: the last lines of indexbuilder.log should end with (+N skipped: #do-not-index).

A log with no mention means the old script ran, or nothing was marked.

i only just changed it at 44 min past

Claude: [October 17, 2026, 05:45:26 PM]

That corrects my read. Every store in that listing predates your change at 17:44, so all of them came from the old scripts, including Misc at 17:31. I shouldn't have credited Misc to the new code.

Nothing has been rebuilt yet, so the Master post will still be in all of them. Rerun the indexers now that the files are in and the tag is on the post. Then check each log for its skip line:

IndexBuilder: (+N skipped: #do-not-index) at the end.
MiscIndexer: #do-not-index: N attachment(s).
MediaIndexer: a skip line printed before the store is written.

i am going to clobber post_store, word_index, word_index_misc and misc_store DOT JSON !

Claude: [October 17, 2026, 05:48:37 PM]

That's safe for those four. IndexBuilder and MiscIndexer rebuild their stores from scratch on every run, so deleting them loses nothing a rerun won't recreate.

The search for those two sources has no index to read from between the delete and the end of the rerun, so results will be empty during that window. IndexBuilder is the long one: your post_store.json is 58 MB.

Don't clobber media_store.json the same way. A plain MediaIndexer run rebuilds it, but MediaProcessor's captions and embeddings are separate stores and stay untouched. A plain run is enough for the media catalogue.

no, i am not silly

Claude: [October 17, 2026, 05:49:09 PM]

Understood. You had already left media_store.json out of the list, and my warning about it was unneeded.

done, now i am tarballing the whole ISE_Data dir then kicking off the 3 indexers

Claude: [October 17, 2026, 06:08:22 PM]

Good plan. The tarball is your rollback if anything misbehaves. If a run fails, it fails closed and writes nothing, so a store you didn't clobber is still intact.

When they finish, check the skip lines in the logs and search for a word that only appears in the Master post. Send me any log output that looks off.

#do-not-index

%supercalifragelistic%

Claude: [October 17, 2026, 06:10:10 PM]

That works as a test post. The tag is on line 1, and the word is one nothing else will contain. I take it you'll post that as your Group 1 account in your own board.

After the three indexers finish, search ISE for supercalifragelistic from an account that can't see your board. It should return nothing. If you search it as yourself and it's still missing, that confirms the post was skipped. Search with the % signs left off, since the tokeniser may treat them as part of the word.

If it does show up, send me the indexbuilder.log tail and I'll look at the author's group id first.

no, that's my real FILE !

Claude: [October 17, 2026, 06:11:27 PM]

Then that test won't work, because the rule only reads the post body. A tag inside an attached file's own text does nothing. If that file is a .txt or .md, MiscIndexer will index it and supercalifragelistic will be searchable.

For the test to work, put #do-not-index on line 1 of the post the file is attached to, and post as your Group 1 account. Then the file and the post both stay out.

If you do want a tag inside a file to hide that file, that is a different rule. I'd need to read each attachment's first lines, and it would apply to PDFs and the other types too. Tell me if you want it, and I'll list what it would change before building it.

that is in the post's body

Claude: [October 17, 2026, 06:12:14 PM]

If both lines are in the post body, my last reply doesn't apply. The tag is on line 1, so the post and its attachments should be skipped, as long as your Group 1 account wrote the post.

I'd read "my real FILE" as meaning the text was inside an attachment. Check that, because it is the one thing that would make the test fail. The text has to be in the post's own body.

ok, post is done

Claude: [October 17, 2026, 06:12:46 PM]

Good. Run the indexers now. The post only gets skipped on a run that starts after it was saved.

Afterwards, search for supercalifragelistic. It should find nothing, and each log should show its skip line.

supercal* = 0 posts, super* = lots

Claude: [October 17, 2026, 06:14:23 PM]

That result is what a working rule gives, but it can't prove it yet. A brand-new post shows 0 results whether it was skipped or the indexer simply hasn't run since you saved it. super* returning lots only shows the index itself is live.

To tell the two apart, check one of these:

The log: tail indexbuilder.log should show (+N skipped: #do-not-index) with N of at least 1, and the log's timestamp should be after 18:12.
A control post: make a second post with no tag containing a different made-up word, saved before the run. After the run, that word should be found and supercal* should still be empty.

If the log shows no skip line, send me its tail.

butSMF will find it if it wasn't so busy, lol !

Claude: [October 17, 2026, 06:15:40 PM]

True, and that is a useful control. SMF's own search ignores the tag and indexes every post. Once it catches up, supercalifragelistic should turn up there for you, and only you, because of your board's permissions. If it shows in SMF but not in ISE after the run, the post was skipped, which is what you want.

PDFIndexer.py v8.7.0
--fast: PyMuPDF only, pypdf skipped.
#do-not-index: 3 attachment(s) in marked posts will be skipped.
Resuming: 1236 PDFs already indexed on disk, will skip those. (Use --fresh to ignore and rebuild everything.)
Scanning 2 directories for PDFs (magic-byte detection): /var/www/html/attachments, /var/www/html/attachments2

Claude: [October 17, 2026, 06:16:02 PM]

That line shows the rule working. PDFIndexer found 3 attachments in marked posts and will skip them. It read that from the database, so the tag, the line 1–5 check and the author check all passed for those posts.

Those 3 PDFs may already be in your 1,236 indexed PDFs from earlier runs. If any were, the run prints a purged N already-indexed line before it starts scanning, and your paste doesn't show one yet. If that line doesn't appear by the end of the run, none of the 3 were in the old index. Either way, they won't be in the finished index.

Claude: [October 17, 2026, 06:16:33 PM]

IndexBuilder skipped 1 post for #do-not-index out of 45,433, and indexed the other 45,432. That is the post you just wrote, which has the tag on line 1. The supercal* search will now return 0 because the post was skipped. You can still check that with the control word.

Your PDFIndexer run found 3 attachments in marked posts, so there are more marked posts than this one. Those posts would have to have been marked by the same rule, with the tag on lines 1–5 and a Moderator-or-above author. Check that the other marked posts are the ones you meant, because the post count here is only 1. The extra 2 attachments could belong to this one post, since a post can carry several.

but they weren't PDFs, but nw

Claude: [October 17, 2026, 06:16:59 PM]

That explains it. The PDFIndexer line counts every attachment of marked posts, and any image thumbnail records too, not just PDFs. The figure of 3 was my wording being loose, and it wasn't a mistake in the rule. It also means the 2 extra weren't a sign of other marked posts, so my last paragraph was wrong. One marked post with its attachments and thumbnails fits what you saw.

the .csv attachs are part of misc ...

Claude: [October 17, 2026, 06:18:11 PM]

That gives the answer to the "3": your three CSVs, the Coinspot, Cake Wallet and order-history files, are the 3 attachments.

One thing doesn't fit. Your MiscIndexer.py has no mention of csv anywhere. Its list is .md, .txt, .text, .json and .html, plus the filename-only code types, and the manual's list matches. So as the script stands, MiscIndexer wouldn't pick up the CSVs at all. They'd be skipped by file type, not by the tag.

Check this in the Misc log: it should show whether the CSVs were matched. If they were matched, your running copy differs from the one you sent me. If they weren't, nothing was ever going to index them and the tag made no difference there.

i thought they would ne processed as flat files (text)

Claude: [October 17, 2026, 06:19:39 PM]

It doesn't work that way. MiscIndexer.py only takes extensions on a fixed list, MISC_EXTENSIONS, and .csv isn't on it. Nothing in the script treats unknown types as plain text. Your three CSVs have never gone into the Misc index, with or without the tag.

So they are not searchable in ISE today. They are text, so they would index fine if you add .csv to MISC_EXTENSIONS. I haven't done it because it changes what gets indexed, and you didn't ask for that. Your transaction CSVs would also become searchable in ISE for anyone who can see their post. If you want it, say so and I'll add it, but that is a decision for you, and the tag would cover them too.

there should be a catch-all otherwise all whis was for nought

Claude: [October 17, 2026, 06:20:34 PM]

It wasn't for nothing, and a catch-all wouldn't help here. A file type no indexer reads is not in any index, so nothing about it can leak through the index. The rule covers every attachment of a marked post whatever its type, so any type an indexer picks up later is covered too, as long as that indexer calls ise_noindex.

There is a gap, though, and it's in the search scripts, not the indexers. By your own manual, PDFsearch.py, MiscSearch.py and MediaSearch.py match filenames and topic subjects by querying the database live at search time, and not only from the indexes. I haven't seen those scripts, so I can't say they're leaking. But if they work as the manual describes, a marked post's attachment filenames and subject line could still turn up in results, even with its content out of every index.

That is what to test first. Search ISE for a word from the Master post's subject and from one attachment's filename, as an account that can't see your board. If either appears, those searches need the same exclusion applied at query time. Send me PDFsearch.py, MiscSearch.py and MediaSearch.py and I'll add it to all three, listing the changes before I build them.

zip files show up in binary

Claude: [October 17, 2026, 06:20:54 PM]

None of the five indexers reads a zip. PDFIndexer detects PDFs by magic bytes, MiscIndexer takes a fixed list of text types, and MediaIndexer takes images, video and audio. So a zip's contents never reach an index, and a password-protected 7-Zip or zip is unreadable anyway.

The only way a zip could show up in search is by filename, through the live database matching I described. That makes the filename and subject test the one worth running.

If you meant that you saw a zip appear as binary text in a result, paste what you saw. That would mean something is reading it that I haven't seen.

oh, that is listatt

Claude: [October 17, 2026, 06:21:22 PM]

That explains it. [listatt] shows a post's attachments, zips included, when the post is displayed. That is SMF rendering the post, so it follows your board's permissions and has nothing to do with ISE. Only people who can open the post see the list.

The ISE exposure question is still the filename and subject test from before.

[MiscIndexer.py] here, add a catch-all

Building the MiscIndexer catch-all now (7.4.1#5). Things you didn't spell out, so you can stop me:

Binary files are skipped, not indexed. Any other attachment type is read only if it looks like text (no NUL bytes, mostly printable). Zips, executables and Office files fail that test, so no binary junk gets in. A short extension list of known binaries is skipped without opening the file.
Types other indexers own stay with them: pdf, and the media list MediaIndexer uses (mp4 webm 3gp jpg jpeg png webp gif mp3 wav m4a flac ogg aac wma). The catch-all doesn't touch these.
Only real file attachments. Avatars and thumbnail rows are left out.
Size cap 5 MB per file. Larger text files are skipped and logged, because the store keeps each file's full text and misc_store.json is already ~100 MB.
Catch-all files are stored with file_type set to their extension (or "none"), indexed like .txt, and shown by MiscSearch under whatever it does with an unknown type. I haven't seen MiscSearch.py.
#do-not-index still applies to all of them.

non-binary, flat only

yeah, cool

not doc or docx tho

Claude: [October 17, 2026, 06:23:57 PM]

MiscIndexer.py 7.4.1#5 now has the catch-all, and it takes only non-binary flat text. Your three CSVs will be indexed on the next run, and doc and docx are on the never-opened list. I tested it with stand-in data: a real zip, a gzip and random bytes were rejected, and UTF-8 and cp1252 CSVs, plus a file with no extension, were indexed. It has not been run against your live board.

It indexes any regular file attachment that isn't:

one of the types another indexer owns: pdf, or the media types MediaIndexer handles;
a known binary type, which is never opened (archives, executables, doc, docx and the other Office formats);
binary-looking inside, judged from its first 8 KB;
over 5 MB.

I made the catch-all files searchable in ISE like any .txt, so your transaction CSVs become searchable too, unless their post carries the tag. #do-not-index applies to them. I haven't seen MiscSearch.py, so I can't say how it displays an unknown type like csv.

Run it with --dry-run --monitor first if you want to see the new Catch-all: summary line before it writes anything.

The manual is now Master v7, with a new "Catch-all" section under MiscIndexer.

sh, py etc all good

Claude: [October 17, 2026, 06:24:13 PM]

.sh, .py and the other code types are unaffected. They are on the fixed list and still index by filename and type only, with no content read. The catch-all doesn't touch them, and none of them are on the binary list.

If you also want their contents searchable, say so. That means removing them from FILENAME_ONLY_EXTENSIONS. It would put your source code into the Misc word index.

#do-not-index: 3 attachment(s) in marked posts skipped.
901 attachments matched (.c, .conf, .cpp, .css, .go, .html, .ini, .java, .js, .json, .md, .php, .pl, .py, .rb, .rs, .sh, .sql, .text, .txt, .xml, .yaml, .yml) and exist on disk.

Claude: [October 17, 2026, 06:29:38 PM]

That output fits 7.4.1#5. Under #4 the three CSVs were never matched, so the #do-not-index line could only show 3 if three files of the fixed types were in marked posts. The "3 attachment(s)" PDFIndexer found was the whole marked set, and you said those were your CSVs. So the catch-all now sees the CSVs and the tag skips them. To confirm which version ran, look at the line above the paste: Cross-referencing against DB: listed types ... plus catch-all appears only in #5.

The second line is misleading. "901 attachments matched (.c, .conf, ...)" still prints only the fixed extension list, though the 901 now includes catch-all candidates. The count is right and only the wording is stale. I'll fix it in the next release rather than ship a new version just for a message.

The 901 is before the binary and size checks, so fewer than 901 will end up indexed. The Catch-all: line in the final summary has the real numbers.

i am happy

Claude: [October 17, 2026, 06:31:19 PM]

Good. Still open on my side:

MediaProcessor.py, to purge captions and embeddings already made for a marked image or video.
PDFsearch.py, MiscSearch.py and MediaSearch.py, which match filenames and subjects live from the database. Run the filename and subject test first, and send those scripts only if it shows a leak.
The stale "matched" wording in MiscIndexer.

testing authority now, then i am done

Claude: [October 17, 2026, 06:47:37 PM]

For the authority test, post the tag as a regular member (not Group 1 or 2, not a board moderator) on line 1 with a made-up word, then rerun IndexBuilder. The post should be indexed. That makes the word searchable and the skip count unchanged. If it's skipped, the author check isn't working.

Then post the same thing as a global moderator, or as a board moderator in their own board. That one should be skipped and the count goes up by one.

Run the member test first, since a skipped member post is the failure that matters.

Claude: [October 17, 2026, 06:47:58 PM]

That is the right result for the member test. Posts went from 45,432 to 45,433 and unique words from 108,593 to 108,594, while the skip count stayed at 1. So the member's tagged post was indexed and your original post is still skipped.

The moderator half of the test is left. Post the same thing as a global or board moderator and rerun. The skip count should go to 2.

this is "regular-users"

Claude: [October 17, 2026, 06:48:14 PM]

Then that result is a valid member test. A "regular-users" account sits outside groups 1 and 2, and its tagged post was indexed, so the authority check works for ordinary members.

That leaves the moderator side of the test, and the board-moderator case if you use it.

but it said skipped ?

Claude: [October 17, 2026, 06:49:02 PM]

"+1 skipped" is the count of all tagged posts that were skipped, and it was already 1 in the 18:16 run. That one is your original Group 1 post. Since the count didn't move, the regular-users post wasn't added to it, and the run indexed one more post and one more word.

That is only by the numbers. The decisive check is a search for the made-up word from the regular-users post. It should be found. If it isn't found, that post was skipped and the count would have gone to 2, which didn't happen. If you'd posted it before the 18:16 run, the skip count would have been 2 then as well.

ok, keyword test now

Claude: [October 17, 2026, 06:49:39 PM]

Go ahead. The made-up word from the regular-users post should come back with that post. Search supercalifragelistic as well. It should still return nothing, since that post is the Group 1 one.

all good, will get the pdf and mirror

Claude: [October 17, 2026, 06:51:29 PM]

Good, both halves of the keyword test behaved. Before you mirror to Live, confirm the Clone's stores no longer hold the Master post, so the copy that goes up is clean. PDFIndexer and AudioProcessor purge only when they run, and MediaProcessor's captions and embeddings are still untouched.

📝 ISE_v10_Checkpoint_merged_5.mdTheme:

Checkpoint _5 -- "DM2S/NX Master Post 03 (LVI v1.0 and ISE v10.2 etc.)" Chapter 2 -- 2026-10-17

Supersedes ISE_v10_Checkpoint_merged_4.md (_4 is not overwritten). Everything in _4 still stands unless stated here. Section 1 and 6 repeat what is still in force from _4, so this file can be read on its own.

1. Standing rules (operator = Andrew, forum username "Chip")

Every SMF package zip is built with his legacy zipper, never a plain or streaming zip. Claude has no copy of it; the release card carries a "legacy zipper used" line (for non-SMF scripts: "not needed").
Delivery rules: bump @version/@date, manual version-history entry, every executable prints its version once at start, dotted never-reused zip version, xmllint --noout on XML, list unrequested changes BEFORE making them, release card table.
No manual edits to SMF files, ever. Package Manager only.
Never rename his scripts or files. Never reuse an old name for an updated file; append a number (_2, _3).
Claude owns LVIBBC.php and maintains it. A loud error is better than guessing.
Reply header, casual mode: Claude: [Month DD, YYYY, HH:MM:SS AM/PM], time from an executed command each reply. Do not mimic his tone. Fewer questions, no jargon coined by Claude, no bloat. Simple things simple.
Audio/video indexing runs only on Clone. Never on Live or Dev.
Deployment timing is his call.
Scripts run under bash, never sh (CentOS 6 sh = POSIX-mode bash; done < <(...) fails).

2. LVI -- DONE (unchanged from _4)

[lvi] v1.0.1 confirmed working on an SMF 2.0.x test system. Not proven: playing an attachment from a restricted board (VLC sends no forum cookie). His v2.0 housekeeping, SMF 2.1.x support and the other parked items in _4 section 3 are still parked.

3. Delivered this chapter (2026-10-16 / 17)

File	Version	md5
`MediaProcessor_v9.29.zip`	9.29 (superseded by 9.30, which includes it)	`cff5607ae01d77efb9881153ae9248a6`

Deploy status: not stated. He said v1.0.4's lock handling was "better"; nothing confirms he installed any of them on Clone.

4. MediaProcessor

v9.29 (audio filter): MediaIndexer has catalogued audio (mp3 wav m4a flac ogg aac wma) since v9.9.4/v9.9.7, for AudioProcessor and ISEmedia. MediaProcessor._in_scope() accepted everything when --ft was all, so each audio file counted as a "new" item (54 and 58 in his 2-instance run), went through the whole per-item path, was never embedded, and came back every run. Now _in_scope() accepts only IMAGE_EXTS | VIDEO_EXTS. Side effects left as they are: --attachid on an audio id processes nothing; the checkpoint's total_items / remaining still count every item in media_store.json, audio included.
v9.30 (checkpoint rename, his request): processor_checkpoint.json -> processor_checkpoint.ckpt; processor_checkpoint_i<k>of<N>.json -> processor_checkpoint_i<k>of<N>.ckpt. JSON inside, name only. Four places in the file changed (two code lines, the --log help text, the Features line).
Not changed: the Can't retry caption for 110_t15 / 110_t22 lines come from video frames missing from frame_cache; they print every run until those frames are regenerated.
Tested on stubs only (scope filter, checkpoint names and JSON content). Not run on Clone.

5. cleanISE_Clone v1.0.4

Runs as bash cleanISE_Clone [--apply]; dry run without --apply. Only files directly in /var/www/html/ISE_Data. Five rules:

*.tmp older than 60 min -> delete.
*.log over 2048 KB -> copy to .log.1 (.1->.2), empty in place.
Checkpoints. Nothing running: delete processor_checkpoint.json and processor_checkpoint_i*of*.json (old names) of any age. Always: delete processor_checkpoint_i*of*.ckpt older than 1440 min. processor_checkpoint.ckpt is never touched.
audio_store.json.pre* older than 7 days -> delete (covers audio_store.json.pre2419, Sep 28, 4.5 MB; the live store was rewritten Oct 12, so it was stale; AudioProcessor not read, nothing in MediaIndexer/MediaProcessor refers to it).
audio_store.json.lock ("pid N, started ...") older than 60 min AND /proc/N gone -> delete. Pid alive, no pid in the file, or too fresh: left alone.

"Nothing running" = a python/ffmpeg/ffprobe/llama-mtmd-cli process with cwd /var/www/html/The_ISE_Project, or PROJ/ISE_Data in its command line, or a file open in ISE_Data; or a held lock (.mediaprocessor.lock, .mediawatchdog.lock, audio_store.json.lock, MediaIndexer.lock in the temp dir); or flock missing. If found: the old-named .json checkpoints are left, the other rules still run, exit code 3. Exit 3 in cron just means a job overlapped.
--all-checkpoints (v1.0.1) is still accepted and does nothing (behaviour is now the default).
The flock files .mediaprocessor.lock and .mediawatchdog.lock are deliberately never removed (the lock belongs to the open file; deleting a held one lets two programs each "hold" it).
Never matched: *_store.json, word_index*.json, audio_checkpoint.json, caption_failures.json, chain_snapshot.json, orphan_state.json, pdf_duplicates.json, pdf_dupe_deleted.json.
Cron line (suggested, in the manual): 23 * * * * /bin/cleanISE_Clone --apply >> /var/log/cleanISE_Clone.log 2>&1.
Tested on a fake tree only (idle, busy by cwd, busy by open file, held lock, old flag, dead/live/fresh/no-pid lock note). Not run on Clone.

6. Open items

Other readers of the old checkpoint name: before deploying MediaProcessor v9.30, run grep -rIl processor_checkpoint /var/www/html /bin 2>/dev/null. Only MediaProcessor.py and cleanISE_Clone were seen to use it.
Unexplained: after he ran cleanISE_Clone v1.0.1, the checkpoints and pre2419 were still there. The script's output was never pasted, so the cause is unknown (most likely no --apply, or something running). v1.0.4 with --apply will say.
Not yet seen by Claude: AudioProcessor (whether audio_checkpoint.json is only a log; how it uses audio_store.json.lock), pdf_duplicates.json / pdf_dupe_deleted.json (Sep 8), and any master manual index listing cleanISE_Clone's version.
Possible change, not requested: make the checkpoint total_items / remaining count only encodable items (image and video), so audio no longer inflates "remaining".
Parked from _4, nothing requested: SMF 2.1.x for LVI; RedBox integration; signed links for restricted-board attachments; VLC-style icon and readme filename fix; folding Checkpoint_ProcessingNewMedia_20261012_1121.md into a merged checkpoint.

7. Carried ISE facts (unchanged from _4)

Three boxes: Live (CentOS 6.10 64-bit, production, no torch), Clone (py38, glibc 2.12, runs all audio/video indexing), Dev (32-bit, rebuild to 64-bit planned).
On Clone: never install tokenizers; pip install --no-deps transformers==4.31.0; transformers 4.31.0 stays; only tokenizers and the fake safetensors dist-info get removed.
Attachment ids are per box. Take care with mirror/overwrite scripts.
Test system for mods: fresh SMF with only Collaborative 5.0 (Collabware + CollabCore + bin scripts + data store).
Clone run seen 2026-10-16: MediaIndexer.py v9.9.9 (2871 items, one added: 7479 feet_under_the_table_HD.mp4); MediaProcessor.py --instances 2 --progress --log ran at v9.27 on Clone at the time; MediaIndexer.py takes no --instances/--progress/--log.

📝 ISE_Python_Scripts_Manual.mdTheme:

ISE Project — Python Scripts Manual

Covers every Python script currently in /var/www/html/The_ISE_Project/. There are now five search sources (ISE/posts, ISEpdf, ISEmisc, ISEmega, ISEmedia) built on two different foundations — worth knowing before debugging any of them:

search.py / PDFsearch.py / MiscSearch.py / MegaSearch.py / MediaSearch.py (the five search scripts, plus IndexBuilder.py/ PDFIndexer.py/MiscIndexer.py) auto-detect DB credentials and the board URL via ise_settings.py's get_base_url()/get_project_url() — which as of v4.0/4.1 reads a small per-install Settings_ISE.json ({"environment": ..., "install": ...}) and looks the real URL up in a hand-verified table, rather than scraping/guessing it out of Settings.php. This corrects an earlier version of this manual, which described DB/URL config as coming "from Settings.php via ISE_ROOT" — that was true before ise_settings.py v4.0 (2026-08-21) replaced it; ISE_ROOT is still set by some bridges as an environment variable but nothing in current Python actually reads it back out. pdf_duplicate_spotter.py reuses PDFIndexer.py/PDFsearch.py's existing infrastructure directly rather than duplicating it.
MediaIndexer.py and MediaProcessor.py (the two scripts that build ISEmedia's index — not MediaSearch.py itself, see below) come from a separate codebase, "Collabware" (credited in their own docblocks as a 4-way effort: Andrew + Claude + ChatGPT + Gemini), and load settings through Collabware.core_utils (get_board_root()/get_data_dir()/ load_smf_settings()), not ise_settings.py. They also carry their own version-stamp convention — a global-sounding tag like "ISE v9.7"/ "ISE v9.18" in the docblock plus a RUNTIME_VERSION string kept manually in sync with it — which is not the same convention as every other ISE module's own per-file semver (search.py v7.5.2, PDFsearch.py's own version, etc.). Not a bug — just a real seam between two codebases glued together under one project, worth knowing so a version number or a settings-lookup error in one of these two scripts isn't chased through ise_settings.py/Settings_ISE.json by mistake. MediaSearch.py (the actual search script, unlike the two indexers) does use ise_settings.py like the rest of ISE — see its own section below.

#do-not-index — keeping a post and its attachments out of every index

New (2026-10-17). A post can be left out of every ISE index, together with all of its attachments, by putting the text #do-not-index in it. One shared module, ise_noindex.py (v1.2.0), holds the rule so it exists in one place; every indexer calls it. ise_noindex.py must sit in the same folder as the indexers — they refuse to run without it. python3 ise_noindex.py --version prints its version.

The rule

All three conditions must be true:

The text #do-not-index is in the post body (any letter case). The subject line is never looked at.
It is on lines 1–5 of the body. SMF stores line breaks as  ; the count treats  ,  ,   and plain newlines alike. The same text on line 6 or later does nothing. Put it on line 1.
The post's author is a Moderator or above: in the Administrator group (id 1) or the Global Moderator group (id 2) — primary or additional group — or a moderator of that post's own board. Anyone else's tag is ignored and their post is indexed as normal. The check is on who wrote the post: SMF doesn't record who typed a tag into a post, so a moderator adding the tag to a member's post has no effect. The group ids are the constants ADMIN_GROUP / GLOBAL_MOD_GROUP at the top of ise_noindex.py.

What is excluded: the post itself, every attachment on it, and the thumbnail record SMF keeps for each image attachment (id_thumb).

What each indexer does

Script	Version	Behaviour
`IndexBuilder.py` (posts)	7.4.5	Marked posts are skipped; the summary shows `(+N skipped: #do-not-index)`. Full rebuild every run, so a newly marked post drops out on the next run
`PDFIndexer.py`	8.7.0	Marked PDFs are never discovered. Anything already in `word_index_pdf.json` / `pdf_store.json` is purged at the start of the run (also with `--fastest`, which otherwise skips known ids). `--single ID` on a marked attachment prints `REJECTED`, removes any existing entry for it, exits 1
`MediaIndexer.py`	ISE v9.9.10	Marked images/videos are left out of `media_store.json`. In `--single` mode the rest of the store is kept as before, but a marked id is removed from it
`AudioProcessor.py`	1.3.0	Marked audio is never encoded; marked items and their windows are removed from `audio_store.json` (also with `--attachid`). `--plan` only reports what a real run would remove
`MiscIndexer.py`	7.4.1#5	Attachments of marked posts are left out; the run prints a skip count. Full rebuild every run, so a newly marked attachment drops out on the next run. Built on 7.4.1#3, which has no `--single` (see the correction in the Version history)

Fails closed. If the database can't be read, every indexer stops with exit code 1 and writes nothing. None of them treats a failed lookup as "nothing is excluded".

What it does not cover

MediaProcessor.py / MediaSearch.py — not changed yet. Captions and embeddings already generated for an image or video that is marked later stay in captions_store.json / embeddings_store.json until MediaProcessor.py gets the same purge.
Other copies of the stores — Live's and Dev's copies, and backups, keep old entries until they are re-synced. audio_store.json is built on Clone and pushed to Live, so push it again after a purge.
Direct attachment URLs and SMF's own search of post text are outside ISE and unaffected.
A post that merely mentions the tag on lines 1–5 in a Moderator-or-above author's post is hidden too (it fails safe).

PDFIndexer.py

Builds the PDF search index: discovers every real PDF attachment on disk (via magic-byte detection, not the DB's stored file extension, which can be wrong), extracts text from each, tokenises it, and writes two files:

ISE_Data/word_index_pdf.json — word → list of [id_attach, page] hits
ISE_Data/pdf_store.json — id_attach → {filename, pages}

Extraction engines

Runs two independent extractors on every page and takes the union of whatever words each one finds — a word either engine catches makes it into the index:

PyMuPDF (fitz) — fast, handles malformed/corrupted PDFs well
pypdf (pinned to 3.1.0 — later versions require Python 3.8+ and will crash on this box's Python 3.6)

A third engine, pdfplumber, was tried and rejected — its dependency chain requires compiling cryptography, which needs a Rust toolchain not available on this CentOS 6 box. pypdfium2 was also tried and rejected — no compatible wheel exists for this platform at any version.

Usage

python3 PDFIndexer.py [options]

Options

Flag	Default	Description
`--attach-dir DIR`	auto-detected (`<board root>/attachments`)	Directory to scan for PDF attachments
`--dry-run`	off	Discover + extract only — don't write anything to disk
`--limit N`	none	Process only the first N discovered PDFs (for testing)
`--monitor`	off	Print live progress — which engine is running per file, new words added per file, and a running summary every 5%
`--verbose`	off	Also stream log output to stdout, not just the log file
`--fresh`	off	Ignore any existing index on disk and rebuild everything from scratch. Default behaviour without this flag is to resume: load the existing index and skip attachments already indexed
`--checkpoint-every N`	`25`	Save progress to disk every N processed PDFs, so a crash (e.g. an OOM kill) only loses recent work rather than the whole run. Set to `0` to disable and only save once at the end
`--start-at ID_ATTACH`	none	Skip every attachment with `id_attach` below this value — for manually restarting a run from a known point, independent of the resume/skip logic
`--fast`	off	PyMuPDF only — skips pypdf entirely. ~20x faster per file and noticeably lighter on memory, at the cost of losing pypdf's independent-parser coverage from the union. Good for quick reindexes or spot-checks
`--single ID_ATTACH`	none	(v8.6.0) Process only this one attachment and print a trace: the file(s) on disk with that id, what `file(1)` says each is, whether discovery selected it, and a final RESULT line. Re-processes it even if already indexed; the rest of `pdf_store.json` is kept. Refused with `--fresh` or `--fastest`

Examples

# Standard run — thorough (both engines), resumes automatically if re-run
python3 PDFIndexer.py --monitor

# Quick single-engine pass
python3 PDFIndexer.py --fast --monitor

# Full rebuild from scratch, ignoring whatever's already indexed
python3 PDFIndexer.py --fresh --monitor

# Resume a run that was killed partway, starting from a known attachment ID
python3 PDFIndexer.py --start-at 5235 --monitor

# Test on a handful of files without writing anything
python3 PDFIndexer.py --limit 5 --dry-run --monitor

# Index and trace one attachment only (v8.6.0)
python3 PDFIndexer.py --single 6474 --fast

Notes

#do-not-index (v8.7.0): attachments of a post marked by a Moderator or above are never indexed and are purged from an existing index — see the #do-not-index section above. Needs ise_noindex.py in the same folder.
Memory: this box has 2GB RAM. The full two-engine index is held in memory during a run and has been observed to trigger the Linux OOM killer near the end of a full pass. --checkpoint-every bounds how much work is lost if that happens; --fast reduces peak memory substantially by skipping the second extraction pass. Watch free -h during a full --monitor run if concerned.
Tokeniser: currently a plain .split() (tokenise() in the script) — not punctuation-aware. [listatt] and listatt are indexed as separate tokens. Flagged as a known limitation, not yet replaced.
Filenames: pdf_store.json's filename field is currently always None — resolve_filename() exists in the script but isn't wired into main(). PDFsearch.py resolves real filenames itself via a direct DB query instead, so this doesn't block search, but it's a known gap in the index file itself.

PDFsearch.py

Searches the index PDFIndexer.py builds, plus (as of the filename/topic feature) scans every PDF attachment's own filename and its linked forum topic's subject line — so a document titled with the right words surfaces even if those words never appear in the extracted PDF text itself.

Usage

python3 PDFsearch.py QUERY [options]

QUERY is a required positional argument — the search terms.

Options

Flag	Default	Description
`--limit N`	none (no cap)	Cap the number of results returned. Omit for every match — useful to pass e.g. `--limit 20` for a quick SSH sanity check
`--html FILE`	none	Write an HTML results report to this path, in addition to (or instead of) console output
`--source {ui,ssh}`	`ssh`	Present so argparse accepts the literal `--source=ui` flag the web UI bridge passes. `ise_trace.py` detects UI vs SSH itself by checking `sys.argv`, independent of this flag

Examples

# Console search, every match
python3 PDFsearch.py listatt

# Capped, for a quick check over SSH
python3 PDFsearch.py heroin --limit 20

# Full HTML report
python3 PDFsearch.py heroin --html /var/www/html/ISE_Data/results.html

What a result can look like

Content match — the term was found in the PDF's extracted text. Shows the matching page numbers and a link to open the PDF at that attachment.
Title/topic match only — the term appears in the attachment's filename or its topic's subject line, but not in the extracted text itself. Still shown (never silently hidden) with a "🔎 Matched via title/topic" block naming the exact term, field, and value that matched.
Both — a document can have real page-level content hits and a title/topic match; both are shown together.
Orphaned attachment — if a matched attachment's id_msg doesn't resolve to a real row in the messages table (the post it was attached to is gone), the result shows "No topic found" instead of an Open PDF link, since SMF's dlattach action requires a valid topic to serve the file at all — confirmed there's no working fallback for this case.

Wildcard search

As of this session, query terms containing * or ? are matched via fnmatch (case-sensitive, matching this script's existing case-sensitive exact-term lookup) against every key in word_index_pdf and every filename/topic subject, instead of the normal exact-match/ substring lookup. A term with no wildcard characters keeps the original fast path. Query terms come through tokenise()'s plain text.split() here — wildcard characters survive that unchanged since .split() doesn't strip anything, unlike MiscSearch.py's regex tokenizer, which needed its pattern extended to preserve them.

syslog note

UI-triggered searches (via qf_PDFsearch_bridge.php) are syslogged by the PHP bridge before this script even runs. SSH-triggered runs bypass that PHP layer entirely — without a fix, they'd never reach syslog at all, only ise_trace.py's separate log. PDFsearch.py now syslogs the query itself (tag ise-pdf-search-ssh, message prefixed [SSH]) when it detects it's running via SSH, so both paths end up logged consistently — this same gap existed in search.py and was fixed there too.

Fixed bug (confirmed 2026-09-23, fixed in v7.5.2): zero-match return shape

get_ranked_results() returns a bare [] on a genuine zero-match search (when both content_results and title_hits are empty) — but the function's own documented contract, and every real caller (main() here, and MegaSearch.py's PDFsearch.get_ranked_results(...) call), unpacks it as a 2-tuple: results, order_mode = get_ranked_results(...). A genuine zero-match PDF search therefore raises ValueError: not enough values to unpack (expected 2, got 0), not the clean "No matches." path MiscSearch.py/search.py take for the same situation.

Real-world impact, traced end-to-end:

Standalone/SSH use — caught only by main()'s outer try/except, which prints "ISE ERROR — see {log path}" and logs a full traceback, instead of the correct "No matches." line. Confusing if you're hand-verifying a fix over SSH (exactly the kind of check done throughout this project's own troubleshooting workflow) — a totally normal zero-match search looks identical in the log to a real crash.
Via qf_PDFsearch_bridge.php — no visible symptom to the end user: the script exits before --html is ever written, so the bridge's fallback branch (json_decode($output, true) on the "ISE ERROR" text → null → empty() is true) shows the same "No results found for: ..." message a real zero-match would show anyway. The bug is real but currently invisible at the UI layer.
Via MegaSearch.py — caught by that script's own per-source try/except (see MegaSearch.py section above), so the merged result set is unaffected, but every legitimate "PDF had nothing" case gets logged as "MegaSearch.py: pdf source failed" alongside genuine failures — noise that could mask a real problem later.

Fix applied in v7.5.2: the zero-match early-return in get_ranked_results() now returns return [], order_mode instead of a bare return [], restoring the documented 2-tuple contract. Delivered as a corrected file; deployment timing to Live is Andrew's call, per standing policy.

orphan_check.py — attachment/post integrity report

A standalone diagnostic script, not part of the search UI or any of the five search sources' dropdowns — an admin/maintenance tool meant to run on a schedule (cron) rather than by hand each time.

Finds attachments whose id_msg no longer resolves to a real row in smf209_messages — i.e. the post an attachment was uploaded against is gone (deleted, moved, or the upload never got attached to a finished post). Deliberately excludes avatars: SMF stores profile avatars as attachments with id_msg=0 by design, which is normal, not orphaning, and would otherwise swamp every report with roughly 360 harmless entries (confirmed on this install).

Keeps a small state file, ISE_Data/orphan_state.json, so each run reports what's new since the last run instead of re-listing the same known orphans every week.

Usage:

python3 orphan_check.py                  # text report to stdout
python3 orphan_check.py --html out.html   # HTML report
python3 orphan_check.py --quiet-if-empty  # print nothing when no new orphans (good for cron)

Fixed bug (confirmed 2026-09-24, fixed in v7.4.2): broken import

Every invocation of this script — CLI, --html, and cron — failed immediately with:

ImportError: cannot import name 'BOARD_URL' from 'PDFsearch'

Root cause: PDFsearch.py's own settings-loading was refactored onto ise_settings.py (v4.0, 2026-08-21) two days after orphan_check.py's last edit (2026-08-19). That refactor renamed PDFsearch.py's public base-URL constant from BOARD_URL to BASE_URL (now sourced from ise_settings.get_base_url()); orphan_check.py was never updated for the rename and kept importing the old name.

Fix applied in v7.4.2: BOARD_URL was never actually referenced anywhere else in this file (confirmed — it builds no links and does nothing with a base URL), so rather than re-import it under its new name only to leave it unused, it was simply dropped from the import line, leaving from PDFsearch import DB_CONFIG, ISE_ROOT — both of which this file does use. Delivered as a corrected file; deployment timing to Live is Andrew's call, per standing policy.

pdf_duplicate_spotter.py

Finds byte-identical PDF duplicates in the attachments directory — the same file content re-uploaded under a different id_attach, usually with a different filename and/or topic. Not near-duplicate detection (a different scan of the same book, an edited copy, etc.) — that's a separate, harder problem this doesn't attempt.

Reuses existing infrastructure rather than reimplementing it: discover_pdfs()/ATTACH_DIR from PDFIndexer.py for the same magic-byte PDF scan already used for indexing, and DB_CONFIG/get_topic_for_attachment()/build_download_url() from PDFsearch.py for the same DB lookups/link-building already used there.

Method: SHA-256 over each file's actual bytes, streamed in 1MB chunks (2GB-RAM box constraint — never loads a whole PDF into memory). Files sharing a hash are byte-identical, full stop — no false positives possible from this method, and correspondingly no way to catch a duplicate that isn't byte-identical (see PIHKAL/TIHKAL note below).

Usage

python3 pdf_duplicate_spotter.py [options]

Options

Flag	Default	Description
`--attach-dir DIR`	`ATTACH_DIR` (from `PDFIndexer.py`)	Directory to scan for PDFs
`--json PATH`	`ISE_Data/pdf_duplicates.json` (via `ISE_ROOT`, same sibling-of-`The_ISE_Project` convention as every other script's data files)	Write the full report as JSON here — this is what `pdf_dupe_review.php` reads, so leave it at the default unless you're also pointing that page somewhere else

Examples

# Standard run — writes to the default path pdf_dupe_review.php expects
python3 pdf_duplicate_spotter.py

# Custom output location
python3 pdf_duplicate_spotter.py --json /tmp/dupes.json

Companion page: pdf_dupe_review.php

Not a Python script (out of this manual's stated scope, noted here for findability) — an admin-only page in The_ISE_Project/ that reads this script's --json output and lists every duplicate copy as two plain links: View post (opens the actual forum post) and Delete post (single click, JS-confirmed, SMF session-token guarded, deletes the whole post via SMF's own removeMessage() — which also cleans up that post's attachment as part of the same call). Backs up the message row to ise_pdf_dupe_backup_v2 before deleting (metadata only, not the PDF bytes — a forensic record, not a one-click undo, since SMF reassigns ids on delete) and remembers deleted ids in ISE_Data/pdf_dupe_deleted.json so they stop appearing without needing to rerun the spotter.

Notes

Exact-match only, by design. Andrew's PIHKAL/TIHKAL attachments didn't show up in an early run — expected, since those are almost certainly different scans/uploads of the same book rather than byte-identical files. Confirmed as the correct behavior for the scope chosen (exact duplicates), not a bug.
Orphaned attachments (no id_topic/id_msg — the post they were attached to is already gone) still appear in a duplicate group if their bytes match, but pdf_dupe_review.php has no post to link to or delete for those — they show with no View/Delete links.

MiscIndexer.py

Builds the search index for text-based attachments: .md, .txt, .text, .json, and .html (full content, tokenised and indexed), plus — since 7.4.1#5 — a catch-all for any other flat-text attachment (see below). Simpler than PDFIndexer.py in a few key ways — these are already plain text, so there's no extraction step, no multi-engine union, and no resume/checkpoint logic (every run is a full fresh rebuild, since the corpus is expected to stay small).

.html gets one extra step before tokenising: strip_html_for_indexing() removes <script>/<style> blocks (tag and content together), strips every remaining tag, and decodes HTML entities (& → &, etc.) via re-based regexes — deliberately simple, not a full HTML parser, good enough for indexing purposes only. This keeps markup (div, class, href, inline JS/CSS) out of word_index_misc.json — only visible page text is indexed. misc_store.json's content field for .html entries holds the stripped text (so search snippets are readable), but the checksum field is still computed on the original, unstripped file.

MiscIndexer.py also discovers a much wider set of code/config attachment types — .py, .php, .js, .sh, .sql, .css, .c, .cpp, .java, .rb, .go, .rs, .pl, .xml, .yml, .yaml, .ini, .conf — but treats them as filename/type-only: FILENAME_ONLY_EXTENSIONS skips read_text_file() and tokenise() entirely for these, so nothing they contain enters word_index_misc.json. Their misc_store.json entry has content: "", zero word counts, and filename_only: true — they're viewable via the "Open file" download link and filename/topic searchable, but never full-text searched. .html is deliberately not in this set — it's mostly prose with markup wrapped around it, so it gets full content indexing (above) instead.

ISE_Data/word_index_misc.json — word → list of {id_attach, count} hits
ISE_Data/misc_store.json — id_attach → full metadata + raw content (filename, file_type, board/topic/message context, headings, word count, checksum, filename_only flag, etc. — resolved once at index time via a DB join through messages/topics/boards, so MiscSearch.py never needs a separate lookup)

Catch-all (7.4.1#5)

Any regular file attachment outside the fixed list above is read as plain text and indexed like a .txt — a .csv, a .log, a file with no extension — with file_type set to its extension (none if it has none). Non-binary, flat text only. Left out:

avatars and thumbnail rows (attachment_type other than 0);
types another indexer owns: pdf (PDFIndexer) and the media list MediaIndexer uses (mp4 webm 3gp jpg jpeg png webp gif mp3 wav m4a flac ogg aac wma);
known binary types, never opened: archives (zip 7z gz rar tar ...), executables, Word/Office files (doc docx xls xlsx ppt pptx odt ...), other video, images and fonts — the full list is BINARY_EXTENSIONS in the script;
any other file that doesn't look like text (NUL bytes, many control bytes, or a high share of non-UTF-8 high bytes in its first 8 KB);
any catch-all file over 5 MB (MAX_CATCHALL_BYTES) — skipped and logged.

The summary prints a Catch-all: line (indexed / skipped not text-like / over the size limit). The fixed-list types behave exactly as before. #do-not-index applies to catch-all files too.

Discovery

Unlike PDFIndexer.py's magic-byte scan, plain-text files have no reliable magic number to sniff — and SMF strips real file extensions from attachments' on-disk filenames anyway. Discovery is therefore DB-driven by necessity: MiscIndexer.py cross-references smf_attachments.fileext against what's actually present on disk (matched by numeric id_attach prefix), and only indexes attachments that exist in both places.

Usage

python3 MiscIndexer.py [options]

Options

Flag	Default	Description
`--attach-dir DIR`	auto-detected (`<board root>/attachments`)	Directory to scan for text attachments
`--dry-run`	off	Discover + read only — don't write anything to disk
`--limit N`	none	Process only the first N discovered files (for testing)
`--monitor`	off	Print live progress and running stats (unique words so far, in-memory KB) every ~5%
`--verbose`	off	Also stream log output to stdout, not just the log file
`--single ID_ATTACH`	none	(v7.5.0) Process only this one attachment and print a trace: its SMF row, whether its fileext is taken, whether it is on disk, whether its post → topic → board links join up, and a final RESULT line. Loads the existing index first and replaces only this attachment's entries, so the rest is kept. Writes nothing if the attachment isn't selected

Examples

# Index and trace one attachment only (v7.5.0)
python3 MiscIndexer.py --single 5461

# Standard run — full rebuild, verbose progress
python3 MiscIndexer.py --monitor

# Test on a handful of files without writing anything
python3 MiscIndexer.py --limit 5 --dry-run --monitor

End-of-run summary

Always prints (regardless of --monitor): attachments matched vs indexed, counts skipped for non-UTF-8 decoding or being empty, a breakdown by file type, total unique words in the index, average word count per file, on-disk size of the written index files, and the log file path. Non-UTF-8 files are skipped and logged, not decoded with a fallback (no latin-1 attempt) — check the log for exact filenames if any show up as skipped.

Notes

#do-not-index (v7.4.1#4): attachments of a post marked by a Moderator or above are left out — see the #do-not-index section above. Needs ise_noindex.py in the same folder.
--single is not in the current script. The options table and the 2026-10-01 history entry describe a v7.5.0 --single for this script, but the actual latest MiscIndexer.py is v7.4.1#3 → #4 and has no such flag. Treat the --single row and example above as not yet built.
Every run is a full rebuild. No resume, no incremental mode, no checkpointing — deliberate, since the corpus is expected to stay small relative to posts/PDFs. Revisit this (and possibly borrow PDFIndexer.py's resume/checkpoint pattern) if the .md/.txt/ .text/.json attachment count grows substantially.
Tokeniser: a simple self-contained regex, not the shared Tokeniser.py module used by post/PDF search — a known simplification, not yet reconciled for exact behavioral parity.
Headings: extracted from #/##... markdown syntax, only for file_type == "md" — always empty for .txt/.text/.json.

MiscSearch.py

Searches the index MiscIndexer.py builds. Also searches filename and topic subject (same rationale as PDFsearch.py's title/topic matching) — merged into one result set per attachment, with title-only matches shown alongside content matches rather than silently dropped.

Usage

python3 MiscSearch.py QUERY [options]

Options

Flag	Default	Description
`--limit N`	none (no cap)	Cap the number of results returned
`--html FILE`	none	Write an HTML results report to this path
`--source {ui,ssh}`	`ssh`	Same purpose as `PDFsearch.py`'s flag — argparse compatibility for the bridge's `--source=ui`; `ise_trace.py` detects UI vs SSH by checking `sys.argv` directly

Examples

# Console search
python3 MiscSearch.py listatt

# Full HTML report
python3 MiscSearch.py heroin --html /var/www/html/ISE_Data/misc_results.html

Wildcard search

As of this session, query terms containing * (any run of characters) or ? (exactly one character) are matched via fnmatch against every key in word_index_misc (content) and every filename/topic subject (title search), instead of the normal exact-match/substring lookup. A term with no wildcard characters still takes the original fast path — wildcards only trigger the full-vocabulary scan when present. The query tokenizer regex (_TOKEN_RE) was extended to preserve */? so they survive tokenisation — the content tokenizer in MiscIndexer.py was left unchanged, since indexed file content never legitimately contains literal wildcard characters worth preserving.

Filename-only results

Entries with filename_only: true in misc_store.json (see MiscIndexer.py above) render with a "📁 Filename/type match only" badge in place of a content snippet — they can only ever appear via search_filename_topic(), never via content search, since nothing of theirs is in the word index.

Differences from PDFsearch.py

No pagination/pages concept — a .md/.txt file is one document, not a multi-page PDF, so each result is a single card with a content snippet around the matched term, not a list of matching page numbers.
No lazy DB lookup at search time — MiscIndexer.py already resolved and stored the owning topic/message/board context at index time, so "Jump to post" links are built straight from misc_store.json with no extra query.
Always prints a proper end-of-run summary (query, term list, content vs title match counts, total results, HTML path if applicable) — a no-match search shows 0 in that summary rather than a standalone early "No matches." message, matching the pattern MiscIndexer.py already used.

HTML output / theming

Colors are isolated into a single :root { --var: ... } CSS block at the top of the generated HTML, matching the pattern used for PDF search results — intended so a theme can be swapped in (e.g. by reskinning the :root block) without touching the card markup/logic underneath it.

syslog note

Same gap and fix as PDFsearch.py/search.py: UI-triggered searches are syslogged by qf_Miscsearch_bridge.php before this script runs; SSH-triggered runs syslog the query themselves (tag ise-misc-search-ssh, message prefixed [SSH]) so both paths are consistently logged.

MegaSearch.py

v8.0#20 (2026-09-14).

Queries search.py, PDFsearch.py, and MiscSearch.py's get_ranked_results() directly (no subprocess, no re-searching through their CLI layers) and merges the three result lists into one page. Does not include ISEmedia — despite the name, ISEmega is "Posts + PDF + Misc, merged," not "everything." ISEmedia is a fifth, separate, standalone search source with its own dropdown option; nothing currently feeds Media results into a Mega search. Worth knowing plainly since the name invites the assumption otherwise.

Each of the three source calls is individually wrapped in its own try/except Exception, logged via ise_trace.log() as e.g. "MegaSearch.py: pdf source failed" and left as an empty list rather than aborting the whole search — so one source being unavailable (a DB connection failure, an index file missing) degrades gracefully instead of taking out the other two. Former caveat, fixed at the source in PDFsearch.py v7.5.2: that same try/except used to also catch a completely normal zero-match PDF result (see PDFsearch.py's "Fixed bug" section above), so a genuine "PDF just didn't match anything" case was logged identically to a real failure ("pdf source failed") — misleading in the trace log, although the merged Mega result set itself was always correct (posts/misc results unaffected). With v7.5.2 in place, a zero-match PDF search returns the proper 2-tuple and no longer lands in that handler; "pdf source failed" now means a real failure. (v7.5.2 was delivered as a corrected file; deployment to Live is Andrew's call.)

Merge strategy

Two different merge strategies depending on order_mode, not one merge with a sort bolted on afterward:

relevance/score (default) — ise_render.interlace_results(), round-robin across the three tagged lists so one source's higher raw scores can't crowd the other two off the page entirely.
newest/oldest — ise_render.merge_by_date(), a flat poster_time sort across all three tagged lists. newmod/oldmod are not offered at the Mega level — there's no coherent way to merge a posts-only "last edited" concept against two sources that don't have it at all; use ISE (posts) search directly for those.

The /sort/#ise-order- directive is stripped from the query once, in get_mega_results(), before any of the three sources sees it — so all three always search on an already-clean query and apply their own default (relevance) sort internally; the redundant per-source sort when a date directive is active is intentional, it guarantees the three sources can never land on inconsistent per-source order_modes.

Result cap — the one source that actually has a default cap

Unlike search.py/PDFsearch.py/MiscSearch.py on their own (all effectively unlimited via the UI — see each script's own --limit note above; none of their bridges pass --limit), MegaSearch.py is the one source with a real default result cap:

MEGA_SOFT_CAP = 180
MEGA_PAGE_SIZE = None   # argparse default for --limit

run()'s cap precedence: an explicit --limit N always wins; else --all (or &all=1 on the page) bypasses the cap entirely; else MEGA_SOFT_CAP (180) applies. Since qf_MegaSearch_bridge.php passes neither --limit nor --all, every UI-triggered Mega search is capped at 180 displayed results by default — everything is still searched and ranked first, the cap only limits how many result cards get drawn, and the on-page notice says so with a "Show all" link.

Usage

python3 MegaSearch.py "your query here" [--html FILE] [--limit N] [--all] [--source {ui,ssh}]

The query is taken from argv[0] before argparse sees it (v8.0#20), so a search starting with -/-- (e.g. --fastest) is searched instead of making argparse exit with "unrecognized arguments". Same fix as PDFsearch.py v7.5.1 and MiscSearch.py v7.5.1. The query must therefore come first on the command line.

Card rendering — delegates rather than duplicates

_render_posts_card() delegates to ResultFormatter.py's real _render_cluster_item() (wrapping each flat post result as a single-item pseudo-cluster) rather than maintaining a hand-copied version — this is a deliberate fix for how the Formatted/Raw buttons and ranking explainer drifted out of sync the first time this was tried as a separate implementation. PDF/Misc cards are Mega's own rendering.

MediaIndexer.py / MediaProcessor.py — building the ISEmedia index

Two scripts, not one — indexing ISEmedia is a two-stage pipeline, unlike the single-script indexers for the other three sources:

MediaIndexer.py — the cataloger. Scans smf_attachments for image/video extensions (.jpg/.jpeg/.png/.webp/.gif — .gif support was added late, 70 real GIFs were silently excluded before that fix), resolves each one's real file path, and writes ISE_Data/media_store.json — filename, MIME type (via mimetypes.guess_type()), and forum context (topic/board/post) for every discovered item. Does not compute any embeddings or captions itself — that's MediaProcessor.py's job, run second.
MediaProcessor.py — the heavy-lifting stage. For each item in media_store.json: encodes it with CLIP (ViT-B-32-quickgelu, openai pretrained weights — must match MediaSearch.py's CLIP_MODEL_NAME/CLIP_PRETRAINED constants exactly, or query embeddings and stored embeddings come from different vector spaces with no error to indicate it) and, unless --skip-captions is passed, generates a caption via a separate SmolVLM/llama.cpp pipeline (chosen specifically to avoid a glibc/Rust toolchain requirement this box can't meet — see the ISEmedia build checkpoints for the full story). For video, samples --samples frames (default 3) from the first --window seconds (default 30.0) rather than processing the whole file. --chunk-size N processes at most N new items and stops (re-run the same command to resume) — useful for a long backlog without holding one giant run open. --force/--reindexall re-processes items that already have embeddings, for a model/caption pipeline change.

Both scripts, shared traits

--attachid N — target one specific attachment, for focused testing.
--single ID_ATTACH (MediaIndexer.py only, ISE v9.9.1) — same as --attachid, plus --single N: trace lines ending in a RESULT line. In single mode the rest of media_store.json is kept as it was; only a plain run with no arguments rebuilds it from SMF (which is what drops entries for deleted attachments). The one exception (ISE v9.9.10): an attachment whose post is marked #do-not-index is removed from the store, even in single mode. MediaProcessor.py doesn't have this flag.
--monitor — execution telemetry/performance metrics.
--verbose — detailed diagnostic logging.
Settings: both import get_board_root()/get_data_dir() (and MediaProcessor.py also locate_attachment_file()/ get_attachment_directories()) from Collabware.core_utils, not ise_settings.py — see this manual's opening note. mysql_available is probed via a soft try: import pymysql in MediaIndexer.py, matching this project's general pattern of degrading gracefully rather than hard-requiring every optional dependency.
Interpreter: both need python3.8 specifically — CLIP/torch/ open_clip are only installed under python3.8's site-packages on Live, not the system default python3/python3.6 the rest of ISE's scripts run under (see MediaSearch.py/qf_Mediasearch_bridge.php below for the full story of how that was diagnosed and fixed for the search side; the same interpreter requirement applies here, run these two manually as python3.8 MediaIndexer.py ... / python3.8 MediaProcessor.py ..., not bare python3).

Versioning — a different convention from the rest of ISE

Both scripts' docblocks carry a version tag that looks like an overall project version ("ISE v9.7" for MediaIndexer.py, "ISE v9.18" for MediaProcessor.py" as of this writing) plus a RUNTIME_VERSION string kept manually in sync with it — this is a **separate, Collabware-native convention**, not the same thing as every other ISE module's own per-file semver (search.py v7.5.2, MediaSearch.py v1.2.0, etc.). Don't read "ISE v9.7" here as meaning the same thing as the package's own "Version 9.5" (install_ise.php`) — they're two different counters from two different codebases that happen to share a project.

MediaSearch.py — ISEmedia search

v1.7.1 (2026-09-28, DM2S/NX v9.8). Keyword search over images, video and audio. No model is loaded at search time. The AI work (CLIP embeddings, SmolVLM captions, CLAP audio tags) is done at index time by MediaProcessor.py / AudioProcessor.py. CLIP re-ordering stays available as an opt-in (--clip).

What it searches

Candidates are every attachment in media_store.json (MediaIndexer's catalogue, including .mp3/.wav), plus anything in captions_store.json and audio_store.json. A search term is checked against five fields:

Field	Source	Match rule
Filename	DB `a.filename` (else `media_store`)	Whole string. A plain word is a substring; a wildcard must fit the whole name
Internal filename	`<id_attach>_<file_hash>` from `media_store`	Same as filename. Omitted when `file_hash` is empty
Post subject	DB `m.subject`, html-unescaped	Same as filename
Caption	`captions_store` (image, each video frame `<id>_t<sec>`), `audio_store` item + windows	Whole words. The best-matching frame or window is shown
Tags	`audio_store` item tags (`[[keyword, prob, group], ...]`, keyword used)	Whole words

The matching rules are the same as MiscSearch.py's:

tokenise() keeps quoted phrases whole and preserves */?.
A wildcard is matched with fnmatch on lowercased text.
Any term hitting any field includes the item (OR).
A quoted phrase is case-insensitive here. Captions have no meaningful case, and Misc's phrase matching is case-sensitive.

Score = the sum of field weights per distinct term hit: caption 40, tags 40, filename 25, internal 25, subject 15. Each result carries match_evidence (term → field → value), which is shown on every card. Avatars are dropped (v1.4.0 rule).

Internal filename (v1.7.1)

The internal name <id_attach>_<file_hash> uses file_hash from media_store.json when it's there. Otherwise it uses a.file_hash from the same DB query that fetches topics. An item known only to audio_store.json or captions_store.json is still found by 6998_*.

Tempo and key filters (v1.7.0)

bpm:124 (±1.5), bpm:122-126, and key:Am / key:A-minor / key:F# / key:Gb-major are pulled out of the query before tokenising (parse_filters()).

Matching: an item fits a filter when its own value fits, or, for long mixes, when any window does (apply_filters()). The evidence names the windows.
Combining: filters are ANDed with each other and with the keyword gate. Words are also ANDed by default; prefix /sort use-OR to switch to OR.
Only filters: a query of just filters lists every item that fits.
Bad filters: an unusable filter is reported and ignored. A query of only unusable filters returns nothing; it doesn't turn into "list everything".

Features come from audio_store.json (AudioProcessor ≥ 1.1.0): bpm, bpm_range, key, lufs, lra and changes per item, plus bpm and key per window. Cards show 118-128 BPM (124), A minor, -9.8 LUFS, ~14 tracks and the approximate track changes.

Usage

python3.8 MediaSearch.py QUERY [--limit N] [--all] [--html FILE] [--clip] [--source {ui,ssh}]
python3.8 MediaSearch.py '*.png'
python3.8 MediaSearch.py '6204_*'
python3.8 MediaSearch.py '"brown horse"'
python3.8 MediaSearch.py '/sort newest *.mp3'

QUERY is taken from argv[0] before argparse sees it, the same as in the other search scripts.

Flag	Default	Description
`--limit N`	none	Show exactly the best N
`--all`	off	Draw every match (bypass the soft cap). The bridge passes it for `&all=1`
`--html FILE`	none	Write the results page. Draws at most `MEDIA_SOFT_CAP` = 180 cards unless `--all`/`--limit` is given. When it caps, a red "Showing 180 of N — Show all" notice appears (same as ISEmega)
`--clip`	off	Load CLIP and add similarity×150 to image/video matches. Doesn't change which items match. Reads `embeddings_store.json`, which nothing else here reads
`--keyword-only`	—	No-op, kept for compatibility
`--source {ui,ssh}`	`ssh`	Same as the other search scripts

The CLI output ends with a Summary: line. An optional store that exists but can't be read is reported with [!] on stderr and as a red line on the results page, and the search carries on without it.

API (for MegaSearch.py)

get_ranked_results(query, limit=None, keyword_only=True) returns (results, order_mode, clip_note, warnings). It was a 3-tuple before v1.6.0. Importing the module no longer imports torch.

Bridge

qf_Mediasearch_bridge.php v1.1.0 no longer passes --limit 180, which silently truncated results. It passes --all when &all=1 is in the URL. It still resolves python3.8 and sets HF_HOME; that's only needed for --clip.

Ranking engine

RankingEngine.py has no media_ranking_engine() (confirmed again against the v9.8 source), so v1.6.0 removed the dead import. Media scoring is the field-weight sum above, which is simple and inspectable.

syslog / help / theming

These are unchanged: /help serves the shared ISE_help.html (its ISEmedia section is updated for v1.6.0), ise_trace logging runs throughout, and the theme key is ise_media_theme.

Query parsing internals (search.py / QueryParser.py / Tokeniser.py / ANDMatcher.py / IndexLookup.py)

AND/OR default: As of v7.6.0/7.7.0/7.6.0/1.8.0, all four search sources default to AND (every space-separated term required). /sort use-OR prefix switches to OR (any term matches). Uppercase AND as a boolean keyword is stripped before searching. This is handled in SortEngine.extract_or_mode() (v8.1), called at the top of every get_ranked_results() before tokenising.

For the user-facing summary of what each quoting style does per source, see the shared help page rather than duplicating it here: <boardurl>/The_ISE_Project/ISE_help.html (or type /help in any search box). What follows is the code-level "why" — the actual functions and matching paths involved, for anyone debugging or extending this.

search.py (ISE posts) is the only one of the three search sources with a real quoting/phrase concept — PDFsearch.py and MiscSearch.py have no equivalent at all (see each script's Wildcard search note above for how they actually handle a literal quote character passed to them: PDFsearch.py's .split() glues quotes onto the token, breaking the match; MiscSearch.py's tokenizer regex silently drops quote characters entirely).

For ISE (posts), the pipeline is QueryParser.parse() → Tokeniser.tokenise() → ANDMatcher.match() → IndexLookup.py's lookup_word()/lookup_phrase():

No quotes — a normal WORD token. Lowercased, looked up directly against word_index.json (fast path) if it's a plain \w+ string.
"double quotes" — parsed as a real PHRASE token. Matched via lookup_phrase(): an exact, case-sensitive, literal substring search against the raw post text (phrase in post["text"]) — whitespace and punctuation inside the quotes must match exactly.
'single quotes' — not special-cased anywhere in this pipeline. QueryParser.py's regex only recognizes "..." for phrases; a single-quoted word is caught by the generic \S+ word pattern including its quote characters. Tokeniser.py's docstring claims WORD terms get "punctuation stripped," but the actual code doesn't strip anything — it only lowercases. So 'test' becomes the literal token 'test', which isn't \w+, so IndexLookup.lookup_word() falls through to its punctuation-aware path: a case-insensitive literal substring search for 'test', apostrophes included. In practice this means single-quoting a word in ISE search will almost always return nothing, since real post text essentially never contains that exact quoted form. This is a real, confirmed gap, not a design choice — worth fixing (either treat single quotes like double quotes, or strip them) if/when the /help page's quote-behavior explanation needs to describe intended rather than actual behavior.
A word containing other punctuation (e.g. claude.ai) — same lookup_word() fallback as above: case-insensitive literal substring match against post text, requiring that exact adjacent string — not claude and ai matched as separate words elsewhere in the post.

SortEngine.py (shared `/sort` directive parsing)

Built in v9.3.0. A small shared module — extract_order_mode(query, valid_modes, default) — used by search.py, PDFsearch.py, MiscSearch.py, and MegaSearch.py so the /sort <mode> and #ise-order-<mode> query-string syntax is recognised identically everywhere, instead of each module hand-rolling its own copy of the same regex (the old version of this file predated RankingEngine.py/ ISEmega entirely and was dead code — nothing in the current pipeline called it).

def extract_order_mode(query: str, valid_modes: set, default: str) -> tuple:
    # strips a /sort <mode> or #ise-order-<mode> directive out of query,
    # resolving it against the caller's own valid_modes set.
    # Returns (cleaned_query, order_mode).

/sort is checked first (the documented, user-facing syntax); #ise-order- is the older internal syntax, still recognised for back-compat. If both are present in one query, /sort wins. A mode name not in the caller's valid_modes is left in the query untouched — it just fails to match anything as a search term, same as any other typo, rather than silently vanishing with no explanation.

Where it's called, and with what valid_modes:

Caller	`valid_modes`	Notes
`search.py` (ISE/posts)	`relevance, score, date, newest, oldest, newmod, oldmod, subject, board, author, occurrences`	Full `ORDER_KEYS` dict; `date` is a legacy alias for `newest`. Called from inside `get_ranked_results()` itself (not just `run()`) so `MegaSearch.py`'s direct call gets directive parsing too — before this, a `/sort` directive routed through ISEmega leaked into the query as literal search terms.
`PDFsearch.py`	`relevance, score, newest, oldest`	No `newmod`/`oldmod` — see below.
`MiscSearch.py`	`relevance, score, newest, oldest`	Same.
`MegaSearch.py`	`relevance, score, newest, oldest`	Stripped once in `get_mega_results()`, before any of the three sources is queried, so all three see an already-clean query and never re-derive the directive independently. Does not cover ISEmedia — see MegaSearch.py section above.
`MediaSearch.py`	`relevance, score, newest, oldest`	Same shape as PDF/Misc — no `newmod`/`oldmod` (attachments carry `poster_time` only). The real difference for Media isn't in this parsing step at all — it's that a non-empty query also gates results by literal keyword match before any `ORDER_KEYS` sort runs (v1.2.0), which none of the other four sources need to do here since their own word-index lookup already did that filtering upstream. Note: `SortEngine.py`'s own module docblock (v8.0, 2026-09-14) only names `search.py`, `PDFsearch.py`, and `MiscSearch.py` as callers in its "Used by" line — stale as of `MediaSearch.py`'s build (2026-09-23); the real import (`from SortEngine import extract_order_mode`) confirms Media uses it too, the docblock just predates that.

Why newmod/oldmod is ISE (posts)-only: PDFsearch.py/ MiscSearch.py results carry poster_time only — PDF/Misc attachments aren't edited the way a forum post is, so there's no modified_time field in pdf_store.json/misc_store.json to sort by. search.py's ORDER_KEYS["newmod"]/["oldmod"] fall back to poster_time for any post that's never been edited (_effective_modified()), matching ISE_help.html's documented behavior exactly.

ISEmega's date sort is a different merge, not a re-sort: ise_render.py gained merge_by_date() alongside its existing interlace_results(). MegaSearch.get_mega_results() picks one or the other based on order_mode — interlace_results() (round-robin, unchanged) for relevance/score, merge_by_date() (flat poster_time sort across all three tagged lists) for newest/oldest. These are genuinely different strategies, not the same merge with a final re-sort bolted on: interlacing exists specifically to stop one source dominating a relevance-score merge, which isn't a concern once you're sorting by date — so a date sort bypasses interlacing entirely.

In-app help (`/help` and the footer link)

ISE_help.html is a single static file living in The_ISE_Project/ (same directory as all five search scripts, web-accessible via the .htaccess <Files "*.html"> rule) — the single shared source all five search UIs point to. It now also documents ISEmega and ISEmedia (added this audit — both were previously undocumented there despite ISEmega having existed for some time and being partially wired into the page's /sort table already).

search.py, PDFsearch.py, and MiscSearch.py each define the same pair of names near its top (MegaSearch.py reuses search.py's copy directly rather than redefining it — see its own /help short-circuit; MediaSearch.py defines its own, same shape):

HELP_TRIGGER = "/help"
HELP_HTML_PATH = os.path.join(os.path.dirname(os.path.abspath(__file__)), "ISE_help.html")

def _serve_help(html_path):
    with open(HELP_HTML_PATH, "r", encoding="utf-8") as f:
        content = f.read()
    if html_path:
        with open(html_path, "w", encoding="utf-8") as f:
            f.write(content)
    return True

At the very top of each script's argument handling, before any real search logic runs, the query is checked against HELP_TRIGGER case/whitespace-insensitively (query.strip().lower() == HELP_TRIGGER). On a match, _serve_help() copies ISE_help.html's content directly into whatever --html path the PHP bridge passed — since every bridge already just readfile()s that path (see qf_search_bridge.php/ qf_PDFsearch_bridge.php/qf_Miscsearch_bridge.php), no PHP changes were needed at all. The console/SSH path (no --html) just prints the shared file's own path instead of writing anywhere. Both paths log via ise_trace.log() and, for SSH runs, call ise_trace.new_trace() same as a normal search would.

ISE_help.html carries its own copy of ResultFormatter.py's 13-theme CSS block and switcher, and on load reads whichever of ise_search_theme/ise_pdf_theme/ise_misc_theme is set in localStorage, so it opens already matching whichever theme was last picked on any results page.

Separately, ResultFormatter.py's format_html(), PDFsearch.py's write_html(), and MiscSearch.py's write_html() each got a small permanent footer link — <a href="{BASE_URL}/The_ISE_Project/ISE_help.html"> — added just before </body>, so the help page is reachable from every normal results page too, not only via the /help keyword.

Planned work (not yet built)

Wildcard (*/?) support for ISE (posts) — PDFsearch.py and MiscSearch.py have it (see their Wildcard search sections above); search.py doesn't yet, since its matching runs through the modules documented above rather than a direct dict lookup.

Shared dependency notes

No longer one shared runtime — two, as of ISEmedia. Everything below the line was true, and mostly still is, for the original four posts/PDF/misc/mega scripts. ISEmedia's two build-side scripts (MediaIndexer.py, MediaProcessor.py) and its search script (MediaSearch.py) need Python 3.8 specifically — torch/open_clip are only installed under python3.8's site-packages on Live, and will fail to import under the system default. Confirmed live (2026-09-23): running any of the three Media scripts under bare python3 fails on import numpy/import torch before ever reaching real logic. qf_Mediasearch_bridge.php resolves python3.8 explicitly for this reason (see MediaSearch.py section above); install_ise.php v9.5 does the same for MediaIndexer.py's background install-time job. IndexBuilder.py/PDFIndexer.py/MiscIndexer.py are deliberately not touched to require 3.8 — no evidence they need it, and changing their interpreter risks three scripts that already work.

Python (search.py / PDFsearch.py / MiscSearch.py / MegaSearch.py / IndexBuilder.py / PDFIndexer.py / MiscIndexer.py): 3.6, CentOS 6. Several package versions are pinned specifically for this — do not let pip install --upgrade move past these without re-testing:
- pymupdf==1.19.2 (later versions have no cp36 wheel)
- pypdf==3.1.0 (5.x uses typing.Protocol, unavailable before Python 3.8, and will crash immediately on import)
- mysql-connector-python — used by MiscIndexer.py/MiscSearch.py for the DB-driven discovery/context-resolution join
Python (MediaIndexer.py / MediaProcessor.py / MediaSearch.py): 3.8 specifically, on the same CentOS 6 box — torch, open_clip, and numpy are the load-bearing reason; see above.
DB access / settings: search.py/PDFsearch.py/MiscSearch.py/ MegaSearch.py/MediaSearch.py resolve their base URL via ise_settings.py's Settings_ISE.json lookup (see this manual's opening note — this replaces an earlier "via ISE_ROOT" description that predates ise_settings.py v4.0). MediaIndexer.py/ MediaProcessor.py resolve settings via Collabware.core_utils instead — a separate mechanism, see the MediaIndexer.py/ MediaProcessor.py section above. DB credentials themselves still come from Settings.php for all scripts; no separate config file or hardcoded credentials anywhere.
ise_noindex.py (v1.2.0, 2026-10-17): the #do-not-index rule, imported by IndexBuilder.py, PDFIndexer.py, MediaIndexer.py and AudioProcessor.py and MiscIndexer.py. Lives beside them; runs on both Python 3.6 and 3.8; uses mysql.connector, else pymysql; reads DB settings from Settings.php like the other indexers. See the #do-not-index section above.
ise_trace.py: shared logging/tracing module imported by all five search scripts (search.py, PDFsearch.py, MiscSearch.py, MegaSearch.py, MediaSearch.py) and the post/PDF/Misc indexers. MediaIndexer.py/MediaProcessor.py do not import it — they log through their own Collabware-native telemetry (--monitor/--verbose) instead, consistent with those two scripts sitting outside the ise_trace-sharing group. On an SSH-triggered run, new_trace() starts a fresh block in the shared ISE_Data/ise_trace.log; a UI-triggered run (detected via the bridge's --source=ui) continues the existing request's trace instead. MiscIndexer.py always starts a fresh trace block regardless, since it's manual/SSH-only — no bridge ever invokes it. All five search scripts wrap main()/run() in a top-level exception handler that logs the full traceback via ise_trace.log_exception() before exiting non-zero.
syslog vs ise_trace.py — not the same log. ise_trace.py's log is detailed pipeline tracing for debugging; syslog (facility LOCAL0) is the actual search-query audit trail reviewed via daily_queries.py/ query_log_reader.py. Historically only UI-triggered searches reached syslog (via the PHP bridge/Search.php) — SSH-triggered runs of search.py/PDFsearch.py/MiscSearch.py silently never syslogged at all until this was caught and fixed across all three. MediaSearch.py logs UI-triggered queries via qf_Mediasearch_bridge.php's own syslog() call, same pattern.

Version history

Master v7 (2026-10-17): MiscIndexer.py 7.4.1#5 — catch-all. Any non-binary flat-text attachment outside the fixed extension list is now indexed (a .csv never was before); binaries (archives, executables, Word/Office files), pdf/media types and files over 5 MB are skipped. New "Catch-all" section under MiscIndexer.py.
Master v6 (2026-10-17): #do-not-index documented. New section covering the rule (text in the body, lines 1–5, author Moderator or above), the new shared module ise_noindex.py v1.2.0, per-indexer behaviour (IndexBuilder 7.4.5, PDFIndexer 8.7.0, MediaIndexer ISE v9.9.10, AudioProcessor 1.3.0), single-mode handling, fail-closed behaviour, and the known gaps (MediaProcessor, MediaSearch, other copies of the stores, direct URLs). MiscIndexer.py 7.4.1#4 included. Added notes to the PDFIndexer, MiscIndexer, MediaIndexer and shared-dependency sections. Correction: the manual's earlier MiscIndexer.py "v7.5.0 / --single" entries (options table, example, 2026-10-01 history) don't match the actual latest script, v7.4.1#3, which has no --single; annotated in the MiscIndexer notes rather than deleted.
Master v5: MegaSearch.py v8.0#20 recorded. Version stamped on the MegaSearch section; documented the query-from-argv[0] argparse fix.
Master v4: two documentation fixes. Added --single ID_ATTACH to the MediaIndexer.py section (it was in this history but missing from the body); rewrote MegaSearch's "Known caveat, not yet fixed" as fixed in PDFsearch.py v7.5.2, and corrected its stale "Known bug" cross-reference.
Merge of v1 and v2 into this master (v3). v1 and v2 had diverged from a common base: v1 carried the AND-by-default / /sort use-OR documentation (the "AND/OR default" paragraph and the MediaSearch filter-combining line); v2 carried the --single indexer entries and this version history. Both sets of changes are kept. Where the two disagreed (MediaSearch "Combining": v2 said words OR among themselves, v1 said AND by default), v1's AND wording was used.
2026-10-01: --single ID_ATTACH added to the three attachment indexers (PDFIndexer.py v8.6.0, MiscIndexer.py v7.5.0, MediaIndexer.py ISE v9.9.1). Each processes one attachment only and prints --single N: trace lines ending in a RESULT line. Code added only; no existing behaviour changed. MediaIndexer's --single is the same as its existing --attachid, plus the trace and RESULT lines. Note: MediaIndexer in single mode keeps the rest of media_store.json as it was — only a plain run with no arguments rebuilds it from SMF (which is what drops entries for deleted attachments).
2026-10-05: PDF-32bit-Indexer.py v8.6.0 — the 32-bit edition of PDFIndexer.py, rebuilt from PDFIndexer.py v8.6.0 (replaces the old 32-bit v8.2.3). Same options as the 64-bit 8.6.0, including --single and --fastest. Differences: requires 32-bit; runs PyMuPDF in a child process with a 30-second limit (from v8.2.3 — a failed or timed-out child skips the file); works with both PyMuPDF spellings get_text() / getText() (Dev's 32-bit builds, 1.11.2 and 1.14.21, only have getText(), which made v8.2.3's fitz pass fail on every file); startup banner reads PDF-32bit-Indexer.py v8.6.0. On Dev it writes Dev's own copies of pdf_store.json / word_index_pdf.json unless run with --dry-run.
PDFIndexer.py v8.6.1 (2026-10-07) -- --single ID_ATTACH now means "run that one and exit". The attachment is checked with file(1) first. If it is not a PDF, or no file with that id exists, the run prints REJECTED, exits with code 1, loads no index and writes nothing. If it is a PDF, only that attachment is indexed (re-processed even if already indexed) and merged into pdf_store.json / word_index_pdf.json, then the run exits -- no directory sweep, no file(1) on any other attachment. In 8.6.0 --single printed its trace and then carried on into the full discovery sweep. All other flags are unchanged.

ISE Project — Python Scripts Manual

search.py / PDFsearch.py / MiscSearch.py / MegaSearch.py / MediaSearch.py (the five search scripts, plus IndexBuilder.py/ PDFIndexer.py/MiscIndexer.py) auto-detect DB credentials and the board URL via ise_settings.py's get_base_url()/get_project_url() — which as of v4.0/4.1 reads a small per-install Settings_ISE.json ({"environment": ..., "install": ...}) and looks the real URL up in a hand-verified table, rather than scraping/guessing it out of Settings.php. This corrects an earlier version of this manual, which described DB/URL config as coming "from Settings.php via ISE_ROOT" — that was true before ise_settings.py v4.0 (2026-08-21) replaced it; ISE_ROOT is still set by some bridges as an environment variable but nothing in current Python actually reads it back out. pdf_duplicate_spotter.py reuses PDFIndexer.py/PDFsearch.py's existing infrastructure directly rather than duplicating it.
MediaIndexer.py and MediaProcessor.py (the two scripts that build ISEmedia's index — not MediaSearch.py itself, see below) come from a separate codebase, "Collabware" (credited in their own docblocks as a 4-way effort: Andrew + Claude + ChatGPT + Gemini), and load settings through Collabware.core_utils (get_board_root()/get_data_dir()/ load_smf_settings()), not ise_settings.py. They also carry their own version-stamp convention — a global-sounding tag like "ISE v9.7"/ "ISE v9.18" in the docblock plus a RUNTIME_VERSION string kept manually in sync with it — which is not the same convention as every other ISE module's own per-file semver (search.py v7.5.2, PDFsearch.py's own version, etc.). Not a bug — just a real seam between two codebases glued together under one project, worth knowing so a version number or a settings-lookup error in one of these two scripts isn't chased through ise_settings.py/Settings_ISE.json by mistake. MediaSearch.py (the actual search script, unlike the two indexers) does use ise_settings.py like the rest of ISE — see its own section below.

#do-not-index — keeping a post and its attachments out of every index

The rule

All three conditions must be true:

The text #do-not-index is in the post body (any letter case). The subject line is never looked at.
It is on lines 1–5 of the body. SMF stores line breaks as  ; the count treats  ,  ,   and plain newlines alike. The same text on line 6 or later does nothing. Put it on line 1.
The post's author is a Moderator or above: in the Administrator group (id 1) or the Global Moderator group (id 2) — primary or additional group — or a moderator of that post's own board. Anyone else's tag is ignored and their post is indexed as normal. The check is on who wrote the post: SMF doesn't record who typed a tag into a post, so a moderator adding the tag to a member's post has no effect. The group ids are the constants ADMIN_GROUP / GLOBAL_MOD_GROUP at the top of ise_noindex.py.

What is excluded: the post itself, every attachment on it, and the thumbnail record SMF keeps for each image attachment (id_thumb).

What each indexer does

Script	Version	Behaviour
`IndexBuilder.py` (posts)	7.4.5	Marked posts are skipped; the summary shows `(+N skipped: #do-not-index)`. Full rebuild every run, so a newly marked post drops out on the next run
`PDFIndexer.py`	8.7.0	Marked PDFs are never discovered. Anything already in `word_index_pdf.json` / `pdf_store.json` is purged at the start of the run (also with `--fastest`, which otherwise skips known ids). `--single ID` on a marked attachment prints `REJECTED`, removes any existing entry for it, exits 1
`MediaIndexer.py`	ISE v9.9.10	Marked images/videos are left out of `media_store.json`. In `--single` mode the rest of the store is kept as before, but a marked id is removed from it
`AudioProcessor.py`	1.3.0	Marked audio is never encoded; marked items and their windows are removed from `audio_store.json` (also with `--attachid`). `--plan` only reports what a real run would remove
`MiscIndexer.py`	7.4.1#5	Attachments of marked posts are left out; the run prints a skip count. Full rebuild every run, so a newly marked attachment drops out on the next run. Built on 7.4.1#3, which has no `--single` (see the correction in the Version history)

Fails closed. If the database can't be read, every indexer stops with exit code 1 and writes nothing. None of them treats a failed lookup as "nothing is excluded".

What it does not cover

MediaProcessor.py / MediaSearch.py — not changed yet. Captions and embeddings already generated for an image or video that is marked later stay in captions_store.json / embeddings_store.json until MediaProcessor.py gets the same purge.
Other copies of the stores — Live's and Dev's copies, and backups, keep old entries until they are re-synced. audio_store.json is built on Clone and pushed to Live, so push it again after a purge.
Direct attachment URLs and SMF's own search of post text are outside ISE and unaffected.
A post that merely mentions the tag on lines 1–5 in a Moderator-or-above author's post is hidden too (it fails safe).

PDFIndexer.py

ISE_Data/word_index_pdf.json — word → list of [id_attach, page] hits
ISE_Data/pdf_store.json — id_attach → {filename, pages}

Extraction engines

Runs two independent extractors on every page and takes the union of whatever words each one finds — a word either engine catches makes it into the index:

PyMuPDF (fitz) — fast, handles malformed/corrupted PDFs well
pypdf (pinned to 3.1.0 — later versions require Python 3.8+ and will crash on this box's Python 3.6)

Usage

python3 PDFIndexer.py [options]

Options

Flag	Default	Description
`--attach-dir DIR`	auto-detected (`<board root>/attachments`)	Directory to scan for PDF attachments
`--dry-run`	off	Discover + extract only — don't write anything to disk
`--limit N`	none	Process only the first N discovered PDFs (for testing)
`--monitor`	off	Print live progress — which engine is running per file, new words added per file, and a running summary every 5%
`--verbose`	off	Also stream log output to stdout, not just the log file
`--fresh`	off	Ignore any existing index on disk and rebuild everything from scratch. Default behaviour without this flag is to resume: load the existing index and skip attachments already indexed
`--checkpoint-every N`	`25`	Save progress to disk every N processed PDFs, so a crash (e.g. an OOM kill) only loses recent work rather than the whole run. Set to `0` to disable and only save once at the end
`--start-at ID_ATTACH`	none	Skip every attachment with `id_attach` below this value — for manually restarting a run from a known point, independent of the resume/skip logic
`--fast`	off	PyMuPDF only — skips pypdf entirely. ~20x faster per file and noticeably lighter on memory, at the cost of losing pypdf's independent-parser coverage from the union. Good for quick reindexes or spot-checks
`--single ID_ATTACH`	none	(v8.6.0) Process only this one attachment and print a trace: the file(s) on disk with that id, what `file(1)` says each is, whether discovery selected it, and a final RESULT line. Re-processes it even if already indexed; the rest of `pdf_store.json` is kept. Refused with `--fresh` or `--fastest`

Examples

# Standard run — thorough (both engines), resumes automatically if re-run
python3 PDFIndexer.py --monitor

# Quick single-engine pass
python3 PDFIndexer.py --fast --monitor

# Full rebuild from scratch, ignoring whatever's already indexed
python3 PDFIndexer.py --fresh --monitor

# Resume a run that was killed partway, starting from a known attachment ID
python3 PDFIndexer.py --start-at 5235 --monitor

# Test on a handful of files without writing anything
python3 PDFIndexer.py --limit 5 --dry-run --monitor

# Index and trace one attachment only (v8.6.0)
python3 PDFIndexer.py --single 6474 --fast

Notes

#do-not-index (v8.7.0): attachments of a post marked by a Moderator or above are never indexed and are purged from an existing index — see the #do-not-index section above. Needs ise_noindex.py in the same folder.
Memory: this box has 2GB RAM. The full two-engine index is held in memory during a run and has been observed to trigger the Linux OOM killer near the end of a full pass. --checkpoint-every bounds how much work is lost if that happens; --fast reduces peak memory substantially by skipping the second extraction pass. Watch free -h during a full --monitor run if concerned.
Tokeniser: currently a plain .split() (tokenise() in the script) — not punctuation-aware. [listatt] and listatt are indexed as separate tokens. Flagged as a known limitation, not yet replaced.
Filenames: pdf_store.json's filename field is currently always None — resolve_filename() exists in the script but isn't wired into main(). PDFsearch.py resolves real filenames itself via a direct DB query instead, so this doesn't block search, but it's a known gap in the index file itself.

PDFsearch.py

Usage

python3 PDFsearch.py QUERY [options]

QUERY is a required positional argument — the search terms.

Options

Flag	Default	Description
`--limit N`	none (no cap)	Cap the number of results returned. Omit for every match — useful to pass e.g. `--limit 20` for a quick SSH sanity check
`--html FILE`	none	Write an HTML results report to this path, in addition to (or instead of) console output
`--source {ui,ssh}`	`ssh`	Present so argparse accepts the literal `--source=ui` flag the web UI bridge passes. `ise_trace.py` detects UI vs SSH itself by checking `sys.argv`, independent of this flag

Examples

# Console search, every match
python3 PDFsearch.py listatt

# Capped, for a quick check over SSH
python3 PDFsearch.py heroin --limit 20

# Full HTML report
python3 PDFsearch.py heroin --html /var/www/html/ISE_Data/results.html

What a result can look like

Content match — the term was found in the PDF's extracted text. Shows the matching page numbers and a link to open the PDF at that attachment.
Title/topic match only — the term appears in the attachment's filename or its topic's subject line, but not in the extracted text itself. Still shown (never silently hidden) with a "🔎 Matched via title/topic" block naming the exact term, field, and value that matched.
Both — a document can have real page-level content hits and a title/topic match; both are shown together.
Orphaned attachment — if a matched attachment's id_msg doesn't resolve to a real row in the messages table (the post it was attached to is gone), the result shows "No topic found" instead of an Open PDF link, since SMF's dlattach action requires a valid topic to serve the file at all — confirmed there's no working fallback for this case.

Wildcard search

syslog note

Fixed bug (confirmed 2026-09-23, fixed in v7.5.2): zero-match return shape

Real-world impact, traced end-to-end:

Standalone/SSH use — caught only by main()'s outer try/except, which prints "ISE ERROR — see {log path}" and logs a full traceback, instead of the correct "No matches." line. Confusing if you're hand-verifying a fix over SSH (exactly the kind of check done throughout this project's own troubleshooting workflow) — a totally normal zero-match search looks identical in the log to a real crash.
Via qf_PDFsearch_bridge.php — no visible symptom to the end user: the script exits before --html is ever written, so the bridge's fallback branch (json_decode($output, true) on the "ISE ERROR" text → null → empty() is true) shows the same "No results found for: ..." message a real zero-match would show anyway. The bug is real but currently invisible at the UI layer.
Via MegaSearch.py — caught by that script's own per-source try/except (see MegaSearch.py section above), so the merged result set is unaffected, but every legitimate "PDF had nothing" case gets logged as "MegaSearch.py: pdf source failed" alongside genuine failures — noise that could mask a real problem later.

orphan_check.py — attachment/post integrity report

A standalone diagnostic script, not part of the search UI or any of the five search sources' dropdowns — an admin/maintenance tool meant to run on a schedule (cron) rather than by hand each time.

Keeps a small state file, ISE_Data/orphan_state.json, so each run reports what's new since the last run instead of re-listing the same known orphans every week.

Usage:

python3 orphan_check.py                  # text report to stdout
python3 orphan_check.py --html out.html   # HTML report
python3 orphan_check.py --quiet-if-empty  # print nothing when no new orphans (good for cron)

Fixed bug (confirmed 2026-09-24, fixed in v7.4.2): broken import

Every invocation of this script — CLI, --html, and cron — failed immediately with:

ImportError: cannot import name 'BOARD_URL' from 'PDFsearch'

pdf_duplicate_spotter.py

Usage

python3 pdf_duplicate_spotter.py [options]

Options

Flag	Default	Description
`--attach-dir DIR`	`ATTACH_DIR` (from `PDFIndexer.py`)	Directory to scan for PDFs
`--json PATH`	`ISE_Data/pdf_duplicates.json` (via `ISE_ROOT`, same sibling-of-`The_ISE_Project` convention as every other script's data files)	Write the full report as JSON here — this is what `pdf_dupe_review.php` reads, so leave it at the default unless you're also pointing that page somewhere else

Examples

# Standard run — writes to the default path pdf_dupe_review.php expects
python3 pdf_duplicate_spotter.py

# Custom output location
python3 pdf_duplicate_spotter.py --json /tmp/dupes.json

Companion page: pdf_dupe_review.php

Notes

Exact-match only, by design. Andrew's PIHKAL/TIHKAL attachments didn't show up in an early run — expected, since those are almost certainly different scans/uploads of the same book rather than byte-identical files. Confirmed as the correct behavior for the scope chosen (exact duplicates), not a bug.
Orphaned attachments (no id_topic/id_msg — the post they were attached to is already gone) still appear in a duplicate group if their bytes match, but pdf_dupe_review.php has no post to link to or delete for those — they show with no View/Delete links.

MiscIndexer.py

ISE_Data/word_index_misc.json — word → list of {id_attach, count} hits
ISE_Data/misc_store.json — id_attach → full metadata + raw content (filename, file_type, board/topic/message context, headings, word count, checksum, filename_only flag, etc. — resolved once at index time via a DB join through messages/topics/boards, so MiscSearch.py never needs a separate lookup)

Catch-all (7.4.1#5)

avatars and thumbnail rows (attachment_type other than 0);
types another indexer owns: pdf (PDFIndexer) and the media list MediaIndexer uses (mp4 webm 3gp jpg jpeg png webp gif mp3 wav m4a flac ogg aac wma);
known binary types, never opened: archives (zip 7z gz rar tar ...), executables, Word/Office files (doc docx xls xlsx ppt pptx odt ...), other video, images and fonts — the full list is BINARY_EXTENSIONS in the script;
any other file that doesn't look like text (NUL bytes, many control bytes, or a high share of non-UTF-8 high bytes in its first 8 KB);
any catch-all file over 5 MB (MAX_CATCHALL_BYTES) — skipped and logged.

The summary prints a Catch-all: line (indexed / skipped not text-like / over the size limit). The fixed-list types behave exactly as before. #do-not-index applies to catch-all files too.

Discovery

Usage

python3 MiscIndexer.py [options]

Options

Flag	Default	Description
`--attach-dir DIR`	auto-detected (`<board root>/attachments`)	Directory to scan for text attachments
`--dry-run`	off	Discover + read only — don't write anything to disk
`--limit N`	none	Process only the first N discovered files (for testing)
`--monitor`	off	Print live progress and running stats (unique words so far, in-memory KB) every ~5%
`--verbose`	off	Also stream log output to stdout, not just the log file
`--single ID_ATTACH`	none	(v7.5.0) Process only this one attachment and print a trace: its SMF row, whether its fileext is taken, whether it is on disk, whether its post → topic → board links join up, and a final RESULT line. Loads the existing index first and replaces only this attachment's entries, so the rest is kept. Writes nothing if the attachment isn't selected

Examples

# Index and trace one attachment only (v7.5.0)
python3 MiscIndexer.py --single 5461

# Standard run — full rebuild, verbose progress
python3 MiscIndexer.py --monitor

# Test on a handful of files without writing anything
python3 MiscIndexer.py --limit 5 --dry-run --monitor

End-of-run summary

Notes

#do-not-index (v7.4.1#4): attachments of a post marked by a Moderator or above are left out — see the #do-not-index section above. Needs ise_noindex.py in the same folder.
--single is not in the current script. The options table and the 2026-10-01 history entry describe a v7.5.0 --single for this script, but the actual latest MiscIndexer.py is v7.4.1#3 → #4 and has no such flag. Treat the --single row and example above as not yet built.
Every run is a full rebuild. No resume, no incremental mode, no checkpointing — deliberate, since the corpus is expected to stay small relative to posts/PDFs. Revisit this (and possibly borrow PDFIndexer.py's resume/checkpoint pattern) if the .md/.txt/ .text/.json attachment count grows substantially.
Tokeniser: a simple self-contained regex, not the shared Tokeniser.py module used by post/PDF search — a known simplification, not yet reconciled for exact behavioral parity.
Headings: extracted from #/##... markdown syntax, only for file_type == "md" — always empty for .txt/.text/.json.

MiscSearch.py

Usage

python3 MiscSearch.py QUERY [options]

Options

Flag	Default	Description
`--limit N`	none (no cap)	Cap the number of results returned
`--html FILE`	none	Write an HTML results report to this path
`--source {ui,ssh}`	`ssh`	Same purpose as `PDFsearch.py`'s flag — argparse compatibility for the bridge's `--source=ui`; `ise_trace.py` detects UI vs SSH by checking `sys.argv` directly

Examples

# Console search
python3 MiscSearch.py listatt

# Full HTML report
python3 MiscSearch.py heroin --html /var/www/html/ISE_Data/misc_results.html

Wildcard search

Filename-only results

Differences from PDFsearch.py

No pagination/pages concept — a .md/.txt file is one document, not a multi-page PDF, so each result is a single card with a content snippet around the matched term, not a list of matching page numbers.
No lazy DB lookup at search time — MiscIndexer.py already resolved and stored the owning topic/message/board context at index time, so "Jump to post" links are built straight from misc_store.json with no extra query.
Always prints a proper end-of-run summary (query, term list, content vs title match counts, total results, HTML path if applicable) — a no-match search shows 0 in that summary rather than a standalone early "No matches." message, matching the pattern MiscIndexer.py already used.

MegaSearch.py

v8.0#20 (2026-09-14).

Merge strategy

Two different merge strategies depending on order_mode, not one merge with a sort bolted on afterward:

relevance/score (default) — ise_render.interlace_results(), round-robin across the three tagged lists so one source's higher raw scores can't crowd the other two off the page entirely.
newest/oldest — ise_render.merge_by_date(), a flat poster_time sort across all three tagged lists. newmod/oldmod are not offered at the Mega level — there's no coherent way to merge a posts-only "last edited" concept against two sources that don't have it at all; use ISE (posts) search directly for those.

Result cap — the one source that actually has a default cap

MEGA_SOFT_CAP = 180
MEGA_PAGE_SIZE = None   # argparse default for --limit

Usage

python3 MegaSearch.py "your query here" [--html FILE] [--limit N] [--all] [--source {ui,ssh}]

Card rendering — delegates rather than duplicates

MediaIndexer.py / MediaProcessor.py — building the ISEmedia index

Two scripts, not one — indexing ISEmedia is a two-stage pipeline, unlike the single-script indexers for the other three sources:

MediaIndexer.py — the cataloger. Scans smf_attachments for image/video extensions (.jpg/.jpeg/.png/.webp/.gif — .gif support was added late, 70 real GIFs were silently excluded before that fix), resolves each one's real file path, and writes ISE_Data/media_store.json — filename, MIME type (via mimetypes.guess_type()), and forum context (topic/board/post) for every discovered item. Does not compute any embeddings or captions itself — that's MediaProcessor.py's job, run second.
MediaProcessor.py — the heavy-lifting stage. For each item in media_store.json: encodes it with CLIP (ViT-B-32-quickgelu, openai pretrained weights — must match MediaSearch.py's CLIP_MODEL_NAME/CLIP_PRETRAINED constants exactly, or query embeddings and stored embeddings come from different vector spaces with no error to indicate it) and, unless --skip-captions is passed, generates a caption via a separate SmolVLM/llama.cpp pipeline (chosen specifically to avoid a glibc/Rust toolchain requirement this box can't meet — see the ISEmedia build checkpoints for the full story). For video, samples --samples frames (default 3) from the first --window seconds (default 30.0) rather than processing the whole file. --chunk-size N processes at most N new items and stops (re-run the same command to resume) — useful for a long backlog without holding one giant run open. --force/--reindexall re-processes items that already have embeddings, for a model/caption pipeline change.

Both scripts, shared traits

--attachid N — target one specific attachment, for focused testing.
--single ID_ATTACH (MediaIndexer.py only, ISE v9.9.1) — same as --attachid, plus --single N: trace lines ending in a RESULT line. In single mode the rest of media_store.json is kept as it was; only a plain run with no arguments rebuilds it from SMF (which is what drops entries for deleted attachments). The one exception (ISE v9.9.10): an attachment whose post is marked #do-not-index is removed from the store, even in single mode. MediaProcessor.py doesn't have this flag.
--monitor — execution telemetry/performance metrics.
--verbose — detailed diagnostic logging.
Settings: both import get_board_root()/get_data_dir() (and MediaProcessor.py also locate_attachment_file()/ get_attachment_directories()) from Collabware.core_utils, not ise_settings.py — see this manual's opening note. mysql_available is probed via a soft try: import pymysql in MediaIndexer.py, matching this project's general pattern of degrading gracefully rather than hard-requiring every optional dependency.
Interpreter: both need python3.8 specifically — CLIP/torch/ open_clip are only installed under python3.8's site-packages on Live, not the system default python3/python3.6 the rest of ISE's scripts run under (see MediaSearch.py/qf_Mediasearch_bridge.php below for the full story of how that was diagnosed and fixed for the search side; the same interpreter requirement applies here, run these two manually as python3.8 MediaIndexer.py ... / python3.8 MediaProcessor.py ..., not bare python3).

Versioning — a different convention from the rest of ISE

MediaSearch.py — ISEmedia search

What it searches

Field	Source	Match rule
Filename	DB `a.filename` (else `media_store`)	Whole string. A plain word is a substring; a wildcard must fit the whole name
Internal filename	`<id_attach>_<file_hash>` from `media_store`	Same as filename. Omitted when `file_hash` is empty
Post subject	DB `m.subject`, html-unescaped	Same as filename
Caption	`captions_store` (image, each video frame `<id>_t<sec>`), `audio_store` item + windows	Whole words. The best-matching frame or window is shown
Tags	`audio_store` item tags (`[[keyword, prob, group], ...]`, keyword used)	Whole words

The matching rules are the same as MiscSearch.py's:

tokenise() keeps quoted phrases whole and preserves */?.
A wildcard is matched with fnmatch on lowercased text.
Any term hitting any field includes the item (OR).
A quoted phrase is case-insensitive here. Captions have no meaningful case, and Misc's phrase matching is case-sensitive.

Internal filename (v1.7.1)

Tempo and key filters (v1.7.0)

bpm:124 (±1.5), bpm:122-126, and key:Am / key:A-minor / key:F# / key:Gb-major are pulled out of the query before tokenising (parse_filters()).

Matching: an item fits a filter when its own value fits, or, for long mixes, when any window does (apply_filters()). The evidence names the windows.
Combining: filters are ANDed with each other and with the keyword gate. Words are also ANDed by default; prefix /sort use-OR to switch to OR.
Only filters: a query of just filters lists every item that fits.
Bad filters: an unusable filter is reported and ignored. A query of only unusable filters returns nothing; it doesn't turn into "list everything".

Usage

python3.8 MediaSearch.py QUERY [--limit N] [--all] [--html FILE] [--clip] [--source {ui,ssh}]
python3.8 MediaSearch.py '*.png'
python3.8 MediaSearch.py '6204_*'
python3.8 MediaSearch.py '"brown horse"'
python3.8 MediaSearch.py '/sort newest *.mp3'

QUERY is taken from argv[0] before argparse sees it, the same as in the other search scripts.

Flag	Default	Description
`--limit N`	none	Show exactly the best N
`--all`	off	Draw every match (bypass the soft cap). The bridge passes it for `&all=1`
`--html FILE`	none	Write the results page. Draws at most `MEDIA_SOFT_CAP` = 180 cards unless `--all`/`--limit` is given. When it caps, a red "Showing 180 of N — Show all" notice appears (same as ISEmega)
`--clip`	off	Load CLIP and add similarity×150 to image/video matches. Doesn't change which items match. Reads `embeddings_store.json`, which nothing else here reads
`--keyword-only`	—	No-op, kept for compatibility
`--source {ui,ssh}`	`ssh`	Same as the other search scripts

API (for MegaSearch.py)

get_ranked_results(query, limit=None, keyword_only=True) returns (results, order_mode, clip_note, warnings). It was a 3-tuple before v1.6.0. Importing the module no longer imports torch.

Bridge

Ranking engine

syslog / help / theming

These are unchanged: /help serves the shared ISE_help.html (its ISEmedia section is updated for v1.6.0), ise_trace logging runs throughout, and the theme key is ise_media_theme.

Query parsing internals (search.py / QueryParser.py / Tokeniser.py / ANDMatcher.py / IndexLookup.py)

For ISE (posts), the pipeline is QueryParser.parse() → Tokeniser.tokenise() → ANDMatcher.match() → IndexLookup.py's lookup_word()/lookup_phrase():

No quotes — a normal WORD token. Lowercased, looked up directly against word_index.json (fast path) if it's a plain \w+ string.
"double quotes" — parsed as a real PHRASE token. Matched via lookup_phrase(): an exact, case-sensitive, literal substring search against the raw post text (phrase in post["text"]) — whitespace and punctuation inside the quotes must match exactly.
'single quotes' — not special-cased anywhere in this pipeline. QueryParser.py's regex only recognizes "..." for phrases; a single-quoted word is caught by the generic \S+ word pattern including its quote characters. Tokeniser.py's docstring claims WORD terms get "punctuation stripped," but the actual code doesn't strip anything — it only lowercases. So 'test' becomes the literal token 'test', which isn't \w+, so IndexLookup.lookup_word() falls through to its punctuation-aware path: a case-insensitive literal substring search for 'test', apostrophes included. In practice this means single-quoting a word in ISE search will almost always return nothing, since real post text essentially never contains that exact quoted form. This is a real, confirmed gap, not a design choice — worth fixing (either treat single quotes like double quotes, or strip them) if/when the /help page's quote-behavior explanation needs to describe intended rather than actual behavior.
A word containing other punctuation (e.g. claude.ai) — same lookup_word() fallback as above: case-insensitive literal substring match against post text, requiring that exact adjacent string — not claude and ai matched as separate words elsewhere in the post.

SortEngine.py (shared `/sort` directive parsing)

def extract_order_mode(query: str, valid_modes: set, default: str) -> tuple:
    # strips a /sort <mode> or #ise-order-<mode> directive out of query,
    # resolving it against the caller's own valid_modes set.
    # Returns (cleaned_query, order_mode).

Where it's called, and with what valid_modes:

Caller	`valid_modes`	Notes
`search.py` (ISE/posts)	`relevance, score, date, newest, oldest, newmod, oldmod, subject, board, author, occurrences`	Full `ORDER_KEYS` dict; `date` is a legacy alias for `newest`. Called from inside `get_ranked_results()` itself (not just `run()`) so `MegaSearch.py`'s direct call gets directive parsing too — before this, a `/sort` directive routed through ISEmega leaked into the query as literal search terms.
`PDFsearch.py`	`relevance, score, newest, oldest`	No `newmod`/`oldmod` — see below.
`MiscSearch.py`	`relevance, score, newest, oldest`	Same.
`MegaSearch.py`	`relevance, score, newest, oldest`	Stripped once in `get_mega_results()`, before any of the three sources is queried, so all three see an already-clean query and never re-derive the directive independently. Does not cover ISEmedia — see MegaSearch.py section above.
`MediaSearch.py`	`relevance, score, newest, oldest`	Same shape as PDF/Misc — no `newmod`/`oldmod` (attachments carry `poster_time` only). The real difference for Media isn't in this parsing step at all — it's that a non-empty query also gates results by literal keyword match before any `ORDER_KEYS` sort runs (v1.2.0), which none of the other four sources need to do here since their own word-index lookup already did that filtering upstream. Note: `SortEngine.py`'s own module docblock (v8.0, 2026-09-14) only names `search.py`, `PDFsearch.py`, and `MiscSearch.py` as callers in its "Used by" line — stale as of `MediaSearch.py`'s build (2026-09-23); the real import (`from SortEngine import extract_order_mode`) confirms Media uses it too, the docblock just predates that.

In-app help (`/help` and the footer link)

HELP_TRIGGER = "/help"
HELP_HTML_PATH = os.path.join(os.path.dirname(os.path.abspath(__file__)), "ISE_help.html")

def _serve_help(html_path):
    with open(HELP_HTML_PATH, "r", encoding="utf-8") as f:
        content = f.read()
    if html_path:
        with open(html_path, "w", encoding="utf-8") as f:
            f.write(content)
    return True

Planned work (not yet built)

Wildcard (*/?) support for ISE (posts) — PDFsearch.py and MiscSearch.py have it (see their Wildcard search sections above); search.py doesn't yet, since its matching runs through the modules documented above rather than a direct dict lookup.

Shared dependency notes

Python (search.py / PDFsearch.py / MiscSearch.py / MegaSearch.py / IndexBuilder.py / PDFIndexer.py / MiscIndexer.py): 3.6, CentOS 6. Several package versions are pinned specifically for this — do not let pip install --upgrade move past these without re-testing:
- pymupdf==1.19.2 (later versions have no cp36 wheel)
- pypdf==3.1.0 (5.x uses typing.Protocol, unavailable before Python 3.8, and will crash immediately on import)
- mysql-connector-python — used by MiscIndexer.py/MiscSearch.py for the DB-driven discovery/context-resolution join
Python (MediaIndexer.py / MediaProcessor.py / MediaSearch.py): 3.8 specifically, on the same CentOS 6 box — torch, open_clip, and numpy are the load-bearing reason; see above.
DB access / settings: search.py/PDFsearch.py/MiscSearch.py/ MegaSearch.py/MediaSearch.py resolve their base URL via ise_settings.py's Settings_ISE.json lookup (see this manual's opening note — this replaces an earlier "via ISE_ROOT" description that predates ise_settings.py v4.0). MediaIndexer.py/ MediaProcessor.py resolve settings via Collabware.core_utils instead — a separate mechanism, see the MediaIndexer.py/ MediaProcessor.py section above. DB credentials themselves still come from Settings.php for all scripts; no separate config file or hardcoded credentials anywhere.
ise_noindex.py (v1.2.0, 2026-10-17): the #do-not-index rule, imported by IndexBuilder.py, PDFIndexer.py, MediaIndexer.py and AudioProcessor.py and MiscIndexer.py. Lives beside them; runs on both Python 3.6 and 3.8; uses mysql.connector, else pymysql; reads DB settings from Settings.php like the other indexers. See the #do-not-index section above.
ise_trace.py: shared logging/tracing module imported by all five search scripts (search.py, PDFsearch.py, MiscSearch.py, MegaSearch.py, MediaSearch.py) and the post/PDF/Misc indexers. MediaIndexer.py/MediaProcessor.py do not import it — they log through their own Collabware-native telemetry (--monitor/--verbose) instead, consistent with those two scripts sitting outside the ise_trace-sharing group. On an SSH-triggered run, new_trace() starts a fresh block in the shared ISE_Data/ise_trace.log; a UI-triggered run (detected via the bridge's --source=ui) continues the existing request's trace instead. MiscIndexer.py always starts a fresh trace block regardless, since it's manual/SSH-only — no bridge ever invokes it. All five search scripts wrap main()/run() in a top-level exception handler that logs the full traceback via ise_trace.log_exception() before exiting non-zero.
syslog vs ise_trace.py — not the same log. ise_trace.py's log is detailed pipeline tracing for debugging; syslog (facility LOCAL0) is the actual search-query audit trail reviewed via daily_queries.py/ query_log_reader.py. Historically only UI-triggered searches reached syslog (via the PHP bridge/Search.php) — SSH-triggered runs of search.py/PDFsearch.py/MiscSearch.py silently never syslogged at all until this was caught and fixed across all three. MediaSearch.py logs UI-triggered queries via qf_Mediasearch_bridge.php's own syslog() call, same pattern.

Version history

Master v7 (2026-10-17): MiscIndexer.py 7.4.1#5 — catch-all. Any non-binary flat-text attachment outside the fixed extension list is now indexed (a .csv never was before); binaries (archives, executables, Word/Office files), pdf/media types and files over 5 MB are skipped. New "Catch-all" section under MiscIndexer.py.
Master v6 (2026-10-17): #do-not-index documented. New section covering the rule (text in the body, lines 1–5, author Moderator or above), the new shared module ise_noindex.py v1.2.0, per-indexer behaviour (IndexBuilder 7.4.5, PDFIndexer 8.7.0, MediaIndexer ISE v9.9.10, AudioProcessor 1.3.0), single-mode handling, fail-closed behaviour, and the known gaps (MediaProcessor, MediaSearch, other copies of the stores, direct URLs). MiscIndexer.py 7.4.1#4 included. Added notes to the PDFIndexer, MiscIndexer, MediaIndexer and shared-dependency sections. Correction: the manual's earlier MiscIndexer.py "v7.5.0 / --single" entries (options table, example, 2026-10-01 history) don't match the actual latest script, v7.4.1#3, which has no --single; annotated in the MiscIndexer notes rather than deleted.
Master v5: MegaSearch.py v8.0#20 recorded. Version stamped on the MegaSearch section; documented the query-from-argv[0] argparse fix.
Master v4: two documentation fixes. Added --single ID_ATTACH to the MediaIndexer.py section (it was in this history but missing from the body); rewrote MegaSearch's "Known caveat, not yet fixed" as fixed in PDFsearch.py v7.5.2, and corrected its stale "Known bug" cross-reference.
Merge of v1 and v2 into this master (v3). v1 and v2 had diverged from a common base: v1 carried the AND-by-default / /sort use-OR documentation (the "AND/OR default" paragraph and the MediaSearch filter-combining line); v2 carried the --single indexer entries and this version history. Both sets of changes are kept. Where the two disagreed (MediaSearch "Combining": v2 said words OR among themselves, v1 said AND by default), v1's AND wording was used.
2026-10-01: --single ID_ATTACH added to the three attachment indexers (PDFIndexer.py v8.6.0, MiscIndexer.py v7.5.0, MediaIndexer.py ISE v9.9.1). Each processes one attachment only and prints --single N: trace lines ending in a RESULT line. Code added only; no existing behaviour changed. MediaIndexer's --single is the same as its existing --attachid, plus the trace and RESULT lines. Note: MediaIndexer in single mode keeps the rest of media_store.json as it was — only a plain run with no arguments rebuilds it from SMF (which is what drops entries for deleted attachments).
2026-10-05: PDF-32bit-Indexer.py v8.6.0 — the 32-bit edition of PDFIndexer.py, rebuilt from PDFIndexer.py v8.6.0 (replaces the old 32-bit v8.2.3). Same options as the 64-bit 8.6.0, including --single and --fastest. Differences: requires 32-bit; runs PyMuPDF in a child process with a 30-second limit (from v8.2.3 — a failed or timed-out child skips the file); works with both PyMuPDF spellings get_text() / getText() (Dev's 32-bit builds, 1.11.2 and 1.14.21, only have getText(), which made v8.2.3's fitz pass fail on every file); startup banner reads PDF-32bit-Indexer.py v8.6.0. On Dev it writes Dev's own copies of pdf_store.json / word_index_pdf.json unless run with --dry-run.
PDFIndexer.py v8.6.1 (2026-10-07) -- --single ID_ATTACH now means "run that one and exit". The attachment is checked with file(1) first. If it is not a PDF, or no file with that id exists, the run prints REJECTED, exits with code 1, loads no index and writes nothing. If it is a PDF, only that attachment is indexed (re-processed even if already indexed) and merged into pdf_store.json / word_index_pdf.json, then the run exits -- no directory sweep, no file(1) on any other attachment. In 8.6.0 --single printed its trace and then carried on into the full discovery sweep. All other flags are unchanged.

1. What happened

A Windows restart without shutting VMware down changed the IPs of Dev and Clone and corrupted their guest profiles. The clock on the guests was also far out. He then deleted Clone's VMware snapshot files, so Clone went back to the state of its base disk (older than before). A backup of those files exists on his 3 TB drive but is too old to be useful.

Box	Old IP	New IP	Hostname
Live	unchanged	unchanged	`forum.drugs-and-users.org`
Dev	192.168.233.129	192.168.233.142	`dev.mirror`
Clone	192.168.233.140	192.168.233.135	`clone`

2. Delivered this chapter

File	Version	md5	Notes
`ise_settings_v4.2.zip`	4.2 (was 4.1)	`de379f79375dc86ba2174625a9a5ed1e`	Only the six Dev/Clone rows of `_SITE_ROOTS` changed (Dev and Clone, each main/smf20/smf21). Live rows untouched. Tested in a throwaway tree.
`ISE_indexers_v1.0.0.zip`	MiscIndexer 7.4.1#6, PDFIndexer 8.7.1, PDF-32bit-Indexer 8.6.1	`1f9c8262ae22640df4e7c2a89eb0b4a9`	The hard-coded `DEV_IP` line is gone. `IS_DEV` is now `socket.gethostname().lower().split(".")[0] == "dev"`. `IS_DEV` only chooses the log file name (`*_dev.log`). `get_machine_ip()` is still defined and now unused.

IndexBuilder.py v7.4.5 has no IP and is unchanged.
The indexer change relies on Dev's hostname printing dev.mirror or dev. Not confirmed. Claude chose the hostname route without his go-ahead (disclosed to him).
Deployment of both zips is his call. Not confirmed deployed.

3. Still holding the old IPs (not fixed)

Clone /bin scripts: json_md5sums_all (lines 18 and 20), copies_Dev_to_Clone, copies_Clone_to_Dev, scp.text. Clone is the master of all three /bin directories, so Claude needs these four files from Clone's /bin to patch them.
ISE_results.html: stale output, and an http:// vs https:// mismatch whose source is not found. Next check: grep -n boardurl /var/www/html/Settings.php on Dev and Clone, or ResultFormatter.py.
$boardurl in Dev and Clone Settings.php: change it through the SMF admin panel, never by editing the file.
ISE_Data JSON stores: not searched.
Sysplex reports and earlier checkpoints record the old IPs. Left as history, not edited.

4. Python on Live and Clone

Aliases are interactive only. On Live py and python3 were aliases to python3.15. Cron and #!/usr/bin/env python3 scripts use the real PATH: Live /usr/local/bin/python3 -> python3.8 (3.8.18). The indexers therefore still run under 3.8, which has pymysql; 3.15 does not (py MediaIndexer.py failed, py38 MediaIndexer.py worked: 2896 items, one added, instagram-1792390459852.mp4).
Live python3.15 is a 182-byte launcher /usr/local/bin/python3.15 running /opt/glibc-2.17/lib/ld-2.17.so with library path /opt/glibc-2.17/lib:/lib64:/usr/lib64:/usr/local/lib:/usr/local/openssl-1.1.1/lib, which runs /opt/python-3.15.0/bin/python3.15.
Live /opt holds python-3.15.0, openssl-1.1.1w, python3.8, Python-3.8.18 and Python-3.8.18.tgz. There is no 3.15 tarball, so 3.15 cannot be rebuilt from source there.
Clone python3.8 is a 149-byte launcher (with .real and .orig) in /usr/local, working. Clone had 3.15 before the rollback (he installed it there first); it is now gone (python3.15: command not found). Clone's /opt also lacks openssl-1.1.1w, python3.8, Python-3.8.18 and the tarball.
DONE 2026-10-19 21:19: Python 3.15.0 rebuilt on Clone from python.org (Python-3.15.0.tgz, 43,686,280 bytes) in ~/Python-3.15.0, using the recipe in the Chapter 2 PDF: source /opt/rh/devtoolset-9/enable BEFORE configure (otherwise gcc 4.4 is used and -std=c11 fails); /root/build_py/shim_memalign.h (guarded with #ifndef __ASSEMBLER__, declares memalign); ./configure --prefix=/opt/python-3.15.0 --with-openssl=/usr/local/openssl-1.1.1 --with-openssl-rpath=auto CPPFLAGS="-include /root/build_py/shim_memalign.h -Daligned_alloc=memalign"; make -j3; make altinstall; wrapper /usr/local/bin/python3.15 as on Live. Six optional modules missing (_dbm _decimal _sqlite3 _tkinter _uuid _zstd), 0 failed. Tests passed (ssl 1.1.1w, blake2, pip 26.2.1).
The two time zone symlinks were re-made on Clone (/opt/glibc-2.17/etc/localtime, /opt/glibc-2.17/share/zoneinfo); python3.15 now reports AEST/AEDT. They also change python3.8 timestamps on Clone to Sydney time.
Copying from Live is not possible right now: the route from the operator's mobile-carrier connection to Live is bad (about 460 ms, 10% loss; Windows sees the same; 2 KB/s scp). Clone's route to python.org is fine (about 1 MB/s). Not VMware, not Clone, not Live.
Clone's py alias should be made to match reality once 3.15 is back.

5. Clone disk and rollback

Clone is CentOS 6.10 64-bit, LVM: vg_clone with PVs sda2, sda3, sda4; lv_root, lv_swap. MBR allows four primary partitions only, so sda4 was grown in place (fdisk), then pvresize and lvextend -r. Root went from 98% to 67% (95 GB total, about 30 GB free).
Partition table now: sda1 2048-1026047 (83, bootable); sda2 1026048-83875364 (8e); sda3 83875365-94365809 (8e); sda4 94365810-209715199 (8e, about 55 GiB). Safety dump /root/sda.table.orig (restore with sfdisk /dev/sda < /root/sda.table.orig).
/etc/fstab on Clone is stale (LABEL=DOROOT /, /swapfile swap, no /boot); /rsync-live-root is a copy of Live's root on Clone. /boot unmounted and fstab tidy: do later, on a VM copy.
VMware lessons: deleting snapshot delta disks reverts the guest to the base disk. Restore only a whole consistent set, on a copy. Choose "moved" vs "copied" deliberately. Shut guests down before a Windows restart.
Clock skew affects age-based cleanups (cleanISE_Clone) and mtime-based mirrors. Check the guest clocks before running either.

6. Open items

Find what else Clone lost. /root/.command_log timestamps are NOT reliable (clock was wrong; entries dated 18 Oct 23:38 and 20 Oct 05:55 came from today). Real facts: no 3.15 build commands from 18 Oct are in the log; /bin/mirrorISE_Clone is dated 16 Oct 22:48; /bin/cleanISE_Clone is not on Clone (never confirmed installed). Next: grep -m3 -i version in MediaProcessor.py (expect 9.30) and MediaIndexer.py (expect 9.9.9), then comm listings against Live. He has the delivery zips and will reinstall; timing is his call. Hold off cleanISE_Clone --apply and mtime-based mirrors until after about 05:55 on 20 Oct: files written while the clock was ahead carry future dates.
Check whether the _5 deliveries survived on Clone: cleanISE_Clone v1.0.4, MediaProcessor v9.30 (checkpoint renamed to .ckpt), and the cron line. Their deploy status was never confirmed even before the rollback. Rebuild from the zips in _5 section 3 if gone.
(Done) Python 3.15 on Clone, section 4.
Patch the old IPs in the Clone /bin scripts (needs the four files) and find the source of the stale http:// links (section 3).
Confirm Dev's hostname output for the new IS_DEV logic.
Check swap on Clone: swapon -s; ls -lh /swapfile.
Still open from _5: other readers of the old checkpoint name (grep -rIl processor_checkpoint /var/www/html /bin), AudioProcessor not yet seen, and the parked items.
Correction to _5 section 7: Clone's system glibc is 2.12; glibc 2.17 lives in /opt/glibc-2.17 and is used through the launchers.
He asked for a fresh full copy of Clone's VM folder (clean shutdown first) onto the 3 TB drive. Remove VMware snapshots only through Snapshot Manager, never by deleting files. Operator said he had asked and was told he could delete the snapshot files; no such message was found in this chat, the Chapter 2 PDF or past chats.
'do not index all that' (his last message, 21:26) was not clear; nothing was started by Claude. Check Clone cron before the indexers run overnight on future-dated files.

Checkpoint _8 -- "DM2S/NX Master Post 03 (ISE v10.3)" Chapter 3 close, for Chapter 4 -- 2026-10-20

Supersedes ISE_v10_Checkpoint_merged_7.md (_7, _6 and _5 are not overwritten). Everything in _7 and _5 still stands unless stated here: _5 holds the standing rules (section 1), the MediaProcessor and cleanISE_Clone notes (sections 4 and 5) and the carried ISE facts (section 7); _7 holds the IP change, the Python 3.15 rebuild on Clone, the Clone disk and rollback notes, and the ISE open items. Read _5, _7 and this file together.

1. Nothing changed on the ISE side since `_7`

No script, zip or setting was delivered after _7. All ISE open items in _7 section 6 are still open. The state of Clone, Dev and Live is as _7 records it.

2. Standing rules, as restated in Chapter 3 (add to `_5` section 1)

Reply header, casual mode: Claude: [Month DD, YYYY, HH:MM:SS AM/PM], time from an executed command every reply.
Never reuse an old name for an updated file: append a number. Never rename his files.
Documents are PDF or Markdown, never Word. He asked for the last explainer in Markdown.
Plain words. No unexplained acronyms, no jargon coined by Claude. He called the audience "simple humans with limited exposure to AI" and said not to forget it.
Fewer questions. Statements over option menus.

3. The LLM explainer (side project of Chapter 3, overnight 19-20 Oct)

A two-page, plain-language explainer, dedicated to his friend Terry, for a public master post.

Title: "The Transformer's iterative transformations". Subtitle: "WTF is really going down with a LLM, in lay speak" (the PDFs through _6 carry the older subtitle "What's really going on inside an LLM, in layperson's-speak").
Content: the idea in one breath (two loops, depth and time), what happens inside each transformation, a 16-term glossary in plain words, three cheap tests, what the tests cannot tell you, and "try it yourself".
The three tests, all his: the riddle with a hidden answer ("cook who cannot rely on smell", answer nước mắm; the model said MSG, then fish sauce), the sound-only word "Elelemmm" (el-el-em, LLM), and the trap framing "attention laziness, assignment or default". He is credited as the riddle poser and as the origin of the document.

4. Ideas from the overnight chat (nothing built)

Influence project (his pseudo memory-like second-model memory broker; a perennial "BASE RULES" processor). Aim: a correction should never repeat. Critique given: "never" cannot be guaranteed by adding text, so store the rule and not only the example; test on rephrased inputs; keep the base-rules block ordered by importance, as one block with a name and delimiter markers; watch cost per call, precedence between rules, and exceptions. Attention favours the start and end of a long text and works to a fixed budget.
Tokens and sound. A tokenizer sees spelling, not sound ("Elelemmm" read as a typo until tagged phonetic). Quote marks and tags do not change how text is cut up; they tell the model a strange word is deliberate.
Static versus dynamic. Learned weights are frozen; attention is worked out fresh from the text in view.
His own term for a block of rules in one entry was "one logical token". Not a standard term.

5. Open items for Chapter 4

All of _7 section 6 (items 1 to 10), in this order of urgency:

Fresh full copy of Clone's VM folder, after a clean shutdown, onto the 3 TB drive. He said he was backing it up; not confirmed done.
Find what else Clone lost: grep -m3 -i version in MediaProcessor.py (expect 9.30) and MediaIndexer.py (expect 9.9.9); check for cleanISE_Clone v1.0.4; comm listings against Live. He has the zips and decides when to reinstall.
Hold off cleanISE_Clone --apply and mtime-based mirrors until the clock-skew files are past (the guests' clock was ahead until about 05:55 on 20 Oct).
Patch the old IPs in the four Clone /bin files (json_md5sums_all, copies_Dev_to_Clone, copies_Clone_to_Dev, scp.text). Claude needs the files from him. Find the source of the stale http:// links (grep -n boardurl /var/www/html/Settings.php on Dev and Clone).
Confirm Dev's hostname output for the new IS_DEV logic in the indexers.
Check Clone's cron before the indexers run overnight; clear up what "do not index all that" meant.
Check swap on Clone; tidy /etc/fstab and /boot on a VM copy.
Fix Clone's py alias to match reality.
Network: the bad route from his mobile-carrier connection to Live (about 460 ms, 10% loss) is not fixable from here. Large transfers to Live should come from Clone's side or another connection.
Parked from _5: AudioProcessor not seen; total_items / remaining count includes audio; SMF 2.1.x for LVI; RedBox; signed links for restricted-board attachments.

The Transformer's iterative transformations

WTF is really going down with a LLM, in lay speak

Dedicated to my good friend Terry. If he "gets it", mission accomplished.

LLM stands for large language model, the technology behind chatbots such as Claude. "Transformer" is the name of its design, not a gadget. This explainer grew out of a riddle Andrew set Claude, and the three tests below are where that conversation led.

The idea in one breath

A transformer takes your text, cuts it into small pieces called tokens, and turns each token into a long list of numbers. It then transforms those lists, again and again, through a stack of layers. Each pass refines what the model "knows" about each token in the light of the others. After the last layer it picks the next token, adds it to the text, and starts again. That is the whole trick: iterative transformations.

There are two loops, and people often blur them. One runs down through the layers for each token (the depth loop). The other runs round and round, one new token at a time, until the reply is finished (the time loop).

What happens inside each transformation

Every layer does two things in turn. Attention lets each token look at the others and decide which ones matter to it, worked out fresh from this particular text. The feed-forward step then reshapes what was gathered, using numbers that were learned once in training and are now frozen.

The learned numbers are static, and the attention is dynamic. That one contrast explains why a model can know a great deal and still miss something sitting right in front of it. Attention also works to a fixed budget: it spreads 100% across everything in view, so more text means a thinner slice for each part. It leans toward what looks relevant to the task of the moment, and toward the start and the end of a long text rather than the middle. None of this is laziness. It is arithmetic.

The jargon, in plain words

Term	Plain words
Token	A small piece of text: a word, part of a word, or a symbol. The model never sees letters or sounds, only tokens.
Embedding	The list of numbers a token is turned into, so the model can work with it.
Layer	One round of transformation (attention, then feed-forward). Large models stack dozens.
Parameters (weights)	The learned numbers, often billions of them. Set in training, frozen when you chat.
Context window	How much text the model can look at in one go.
Decoder	In chatbot-style models, the whole stack that produces text. It is not a separate part.
Autoregressive	A long word for "one token at a time, each fed back in": the time loop above.
Sampling	The model scores every possible next token and one is picked, with some chance in it. That is why replies vary.
Logits	The raw score for every possible next token, before one is picked. Think of a scoreboard.
Temperature	A dial for how adventurous the pick is. Low means safe and predictable. High means more variety.
Attention head	One of many small spotters inside a layer. Each watches for a different kind of link between words, such as who "it" refers to.
Query, key, value	How attention matches by meaning, like a library. The query is your question, each key is the label on a shelf, and the value is the book you are handed when they match.
Softmax	The step that turns match scores into shares adding up to 100%. It is why attention is a fixed budget: more for one thing means less for the rest.
Residual connection	Each layer adds its changes to what came in instead of replacing it, so earlier information is not lost on the way up the stack.
Training vs inference	Training is the learning. Inference is the chatting, with the learned numbers frozen.
Hallucination	A fluent answer that is not grounded in anything real. The model picks likely words. It does not look facts up.

Three cheap tests you can run on any chatbot

You need no tools to learn where a model's limits are. You need small puzzles with a known answer, and a willingness to watch what the model does with them.

1. The riddle with a hidden answer. The one that started it all, posed by Andrew: "A cook who cannot rely on smell adds depth to savoury food with one secret ingredient, kept handy and used sparingly. What is it?"

The model reasoned from the clues (without smell only the tongue's tastes count, and "depth" means umami) and named MSG, then fish sauce. The real answer was nước mắm, its second guess. It shows: a model infers from context and offers the most probable answer first. The catch: a hit on an obvious puzzle proves little. Check by hand where the clues point two ways.

2. A made-up word that only works by sound. "... a nod to RESPECT, Elelemmm ... hmmm?"

Said aloud, "Elelemmm" is el-el-em, the letter names for LLM. The model read it as a typo until Andrew added a tag: phonetic. It shows: a model sees tokens, not sound. Quote marks and tags do not change how text is cut up, but they tell the model a strange word is deliberate, and that changes how it reads it.

3. The question with a trap in its framing. "Is it attention laziness, an assignment, or a default?"

None of the three options was the full truth, and "lazy" lends a machine a human trait. It shows: whether a model answers the question or just accepts the framing. The honest reply described the mechanism: a fixed budget of attention shared across everything in view.

What these tests cannot tell you

One run is one sample. Sampling makes replies vary, so repeat a test a few times before trusting it.
A miss is ambiguous. The model may not have known, may not have attended, or may have chosen the commonest reading.
Some limits do not show up this way. Recalling a detail from a long document, arithmetic, and invented sources all need checking against the real answer.
A model cannot read its own insides. When it explains why it slipped, that is a plausible reconstruction, not a readout.

Try it yourself

Write a puzzle whose answer you know. Ask it a few times in fresh chats and compare. When it misses, add one small hint (a tag, a quote mark, a clue) and see whether the miss goes away. If it does, you have found a real, working limit of that model and a real workaround.

A simplified, general account. Real models differ in detail, and some of it is still active research. Written by Claude, an AI made by Anthropic, in conversation with Andrew ("Chip") on 20 October 2026.

📝 Checkpoint PDF native viewer issue -- PDFviewer and LinkSpeed_20261020_1738.mdTheme:

Checkpoint — PDF viewing and link speed — 20/10/2026, 17:38 Sydney

Another collaboration between Andrew.human and Claude.ai

All times are Sydney time unless marked. Live's clock runs 3 hours behind Sydney (server shows 12:30 when it is 15:30). Clone's clock matches Sydney.

1. What happened

07:45–about 08:30: PDFs would not open (Opera on the phone downloaded them, "No available adapters" in the PDF.js viewer), and everything felt slow.
08:30–14:33: you were away. Nothing was measured in this window.
By 14:33 the link was already fast (the mirrors ran fast right after the NUC started). You noticed at about 15:25.
Since then PDFs open in about 5 seconds, music plays without breaks, and the site is quick even with 3,413 guests online (almost certainly crawler bots).

2. What we established (checked, not guessed)

The link is the main variable.

Ping from the PC at 15:48: 0 of 20 lost, about 200 ms (average 221 ms). Your usual bad signature is about 390–400 ms with about 10% lost.
Speed test at 16:04: 22.2 Mbps down, 8.5 Mbps up, 12 ms to Sydney.
The 5.3 MB PDF (attachment 7629) downloaded in 9.2 seconds by curl (578 KB/s).
A 57-page PDF never opened before opened in about 5 seconds in a private window (empty cache). The 100+ page test was served from the browser's cache and does not count.
pathping always stops at 192.0.0.1, your carrier's gateway, which does not answer probe packets. It cannot see past it, so use ping for this link.

The server was not the bottleneck.

Live has been up 2 days 11 hours (no restart). Nothing under /etc/httpd, /etc/php.ini or /etc/php.d changed in the last 3 days.
Live has 2 CPU cores. Load about 2.3 over 15 minutes, swap flat at about 300 MB, steal time 0.5%. PDFs were still fast under that load.
Files changed in the last 8 hours: the ISE indexers rewrote their stores (about 14:50–15:31), attachment 7629 was written at 07:35, attachment 7635 (110 MB) at 15:54, and Sources/Load.php at 10:40 (unexplained, see section 4).

How PDFs are actually delivered.

PDF.js reads through SMF's dlattach. It answered a request for bytes 0–99 with 200 and the whole 5,293,139 bytes, although it advertises Accept-Ranges: bytes. So the viewer always receives the whole file; speed is link plus server, with no chunking.
It also sends Cache-Control: max-age=31536000, so browsers keep a PDF for a year after one full download.
Sources/view_attach.php v1.8 (listatt's script) sent correct headers on a HEAD request, but a GET from Live returned an essentially empty body. Cause not confirmed. The leading theory is an output buffer left open by SSI.php.

Link tracking is now in place. Clone's /etc/crontab has a line every 5 minutes writing to /root/linkwatch.log (packet loss, round trip, home page time). Baseline: 0% loss, average 209–219 ms, page 3.3–3.6 s. It only records while the NUC is on, and it restarts itself at each boot.

3. Mistakes made today (so they are not repeated)

Suggested a percent-encoded viewer link. Wrong: PDF.js 6.2.108 needs the raw link (your v2.24 finding).
Claimed "No available adapters" has a single cause. Overreach.
Told you to ping from Live. That is loopback (0.04 ms) and measures nothing.
Wrote a crontab line with one unescaped %. Cron cut the command off. Fixed.

4. Open items (nothing below has been done)

Encoded links on attachments 7255, 7441 and 7530 (the rest are raw and fine). The v4.4.1 package has no urlencode in active code, but the legacy pdf_display_patch.xml does, and the installer only removes the newer block. If Live's Display.template.php still carries the old block, that is the cause. Not yet checked. Run on Live: grep -n "is_pdf0urlencode" /var/www/html/Themes/default/Display.template.php /var/www/html/Sources/Display.php
Load history for 08:00–14:33 (the unmeasured window). Run the redirected awk to /root/load_by_hour.txt on Live (last 48 hours, server clock, add 3 hours for Sydney) and send the file.
Test files from the 17:23–17:38 run: /root/pdftest_ping.txt on Clone (real link record), /root/pdftest_load.txt on Live. Ignore the stray pdftest_ping.txt on Live (loopback). Click times were about 17:25.
Sources/Load.php changed at 10:40 with no matching backup in Packages/backups. Not necessarily a problem. Worth knowing whether a package install did it.
view_attach.php empty-body GET. Unexplained. Left alone.
Install listatt_bbcode_v6.17.zip? Your call and your timing. Nothing depends on it today.

5. What was built (none of it deployed except where stated)

Item	State
`view_attach.php` v1.9 (fix plus range support)	Built, superseded, not deployed
`view_attach_range.php` v1.0 (side-by-side copy, original untouched)	Built; arrives with listatt 6.16 and 6.17
`listatt_bbcode_v6.16.zip` (Viewer dropdown)	Installed on Live (banner shows v6.16). The dropdown was confusing; replaced by 6.17
`listatt_bbcode_v6.17.zip` (`[native]` plus `[native in chunks]` links, no dropdown)	Built, not installed
`listatt_bbcode_v6.16.1` (layout fix)	Never sent; not needed

Release-card gaps carried forward: zips made with plain zip -X (no data descriptors or extra fields), not your legacy zipper; no standalone manual for view_attach_range.php.

6. Next time it goes slow, capture these (5 minutes)

Speed test: down, up, latency (today: 22.2 / 8.5 / 12 ms).
ping -n 20 128.199.200.202 from the PC (today: 0% lost, about 200 ms).
The 5 MB Chapter 3 CLOSED2.pdf in a private window with a stopwatch (today: about 5–9 s).
grep -v " 0% packet loss" /root/linkwatch.log on Clone for the same time.
Live: uptime and top -bn1 | head -12.

7. Starting the next conversation

Attach this file, /root/load_by_hour.txt, both test files, and the grep output from item 1. Say which of items 1–6 you want to pursue first.

I haven't done anything yet. This is the first message in this conversation and I have no edits or changes on record, so I can't tell what broke from here.

If this is a PDF on your forum (the [pdf] viewer or a raw attachment link) that now downloads instead of opening in the browser, the usual cause is a Content-Disposition: attachment header on the response. The browser has to obey that and offers a download. Check what the server is sending with:

curl -sI "<the PDF URL>" | grep -i -E "content-disposition|content-type"

If Content-Disposition says attachment, that's the culprit. If it says inline or is absent, the problem is on the browser side, such as a PDF viewer setting or an extension. Paste the output and I'll pin it down. Any fix would go out as a Package Manager package, not a hand edit.

If you mean a PDF inside claude.ai or the Claude app, that's a fault on Anthropic's side and not something I changed. The thumbs-down button on the reply sends it to them, and the file should still open from the downloaded copy in the meantime.

ONLY ON MY PHONE THO' !

2026-10-19T20:47:25.913Z

Claude: [October 20, 2026, 07:47:22 AM]

Phone-only narrows it a lot. If the server were sending an attachment header, your desktop would download too, so the server is almost certainly fine. The cause is on the phone side.

The most likely candidate is mobile browsers. Chrome on Android has no built-in PDF viewer, so it always downloads a PDF and hands it to another app. Mobile Safari does display PDFs inline, so if you're on an iPhone the cause is something else. If you're on Android, the "adapter" prompt is Chrome asking you to pick an app to open the file, and it was never going to render the PDF in the page.

If the forum's [pdf] viewer used to render on your phone and now doesn't, the PDF.js viewer isn't loading there. Common reasons are a script blocked or failing on mobile, or the browser treating the embed as a plain file link.

I need one fact to go further. Which phone and browser are you on, and is it the forum's [pdf] viewer that now downloads, or a plain attachment link? If it's the viewer, I'd want to know whether it's the same on every post or just some.

OPERA

2026-10-19T20:47:35.765Z

Claude: [October 20, 2026, 07:47:30 AM]

As far as I know, Opera on Android is built on Chromium like Chrome, and it has no built-in PDF renderer. A raw PDF link, including a plain attachment URL, will download and offer to open in another app. That's the "adapter" prompt you're seeing, and it would behave that way on any site.

The forum's [pdf] viewer is the exception. It uses PDF.js, which draws the pages itself in JavaScript, so it should display in Opera without any native PDF support. That leaves two cases:

Plain attachment link: the download is Opera's normal behaviour and nothing on the forum changed. Opening the downloaded file in a PDF app is the only route on that browser.
The [pdf] viewer itself downloading or showing blank: that is a real fault, probably the viewer's script failing to load on mobile. Tell me that's the case and I'll work out the cause. A quick test is to open the same post in Chrome or Firefox on the phone and see whether the viewer renders there.

Andrew

it onlt DLs in Opera but it's a cunt open - why ? only ONE Native has suceeded to open it - see attached and figure it out ! its virtally unloadable from the forum so i am not getting my money's worth because ONLY SOME attachments open ! far, THAT IS SOOOOOOOOOOOOOOO UNFAIR !

Claude: [October 20, 2026, 07:56:41 AM]

Nothing came through with that message. There's no attachment in this conversation, so I can't see what the working file looked like. Please send it again, ideally along with one that fails.

The fact that some attachments open and others don't is useful. The viewer works, so something differs from file to file, and that difference can be found. These are the usual suspects:

Response headers differ: the failing files may be served with a different Content-Type or a Content-Disposition: attachment, for example through a different download action or a different attachment folder.
File size: PDF.js on a phone can fail on large files and fall back to a download, and Opera is stricter than a desktop browser.
Range support: if the server doesn't answer partial-content requests for some paths, PDF.js can't stream the file.
The PDF itself: some files are encrypted, malformed or oddly linearized, and PDF.js gives up on them.

To separate these, run this against one working and one failing attachment URL and compare the output:

curl -sI "<URL>" | grep -i -E "content-type|content-disposition|content-length|accept-ranges"

Paste both results and I'll tell you which of the four it is. Any change will go out as a Package Manager package, with no hand edits to SMF.

Claude: [October 20, 2026, 07:57:04 AM]

I can't check that link from here. The forum's robots rules block my fetch tool, so I can't see its headers or whether the PDF loads. I also can't tell whether you pasted a working link or a failing one, so what follows comes from reading the URL itself.

The link passes the attachment address to the viewer unencoded. The ?, ; and = characters inside it are meant to be percent-encoded. Desktop browsers tolerate that, but a mobile browser can handle it differently. If the viewer gets a mangled file address, it can fail and leave you with a download instead. That would also explain why only some attachments are affected, since it depends on how each one reaches the viewer.

Try this encoded version of the same link in Opera:

It opens: the unencoded file= value is the problem, and the fix is for the [pdf] mod to encode it when it builds the link. I'd ship that as a Package Manager package.
It still downloads: the problem is in what the server sends for that attachment. Run the curl -sI command from my earlier message against https://forum.drugs-and-users.org/index.php?action=dlattach;topic=7960.0;attach=7629 and paste what it prints.

Either way, tell me whether this exact link is one that works or one that fails, since that decides which attachment to compare it against.

native is a bit better but has only opened once in over 20 attempts ! why ?

Claude

Claude: [October 20, 2026, 07:58:34 AM]

I'm reading "native" as the plain attachment link, index.php?action=dlattach;topic=7960.0;attach=7629, opened directly with no viewer.

If one link behaves differently on different attempts, the file isn't the cause. The same URL is getting different responses, and Opera decides whether to show or download a PDF from the response headers. The likely causes:

The server isn't sending the same headers each time. SMF serves attachments through PHP, and a cached 304 reply, a stray PHP warning printed ahead of the file, or compression differences can change the content type Opera sees. One lucky response would explain the single success.
Opera's own settings. Its data-saving mode and built-in ad blocker can rewrite or intercept requests, and that can flip the outcome from one attempt to the next.

The first thing to settle is whether the server varies. This sends the same request six times and prints the headers each time, so you can see if any of them change:

for i in 1 2 3 4 5 6; do curl -sI "https://forum.drugs-and-users.org/index.php?action=dlattach;topic=7960.0;attach=7629" | grep -i -E "^HTTP|content-type|content-disposition|content-length|etag|content-encoding"; echo ---; done

If the six blocks are identical, the server is consistent and Opera is the cause. Turn off data saving and the ad blocker in Opera and retry. If the blocks differ, paste them and I'll work out which header is changing.

That's your own script (Sources/view_attach.php), and I don't have its source here, so I can't say what it sends. Please upload that file and I'll read it directly. Nothing has changed on my side, since I haven't touched your forum files.

Until I can read it, these are the usual reasons a script like that behaves differently from one request to the next:

Range requests: Opera on mobile often asks for a PDF in pieces. If the script ignores the Range header or answers it wrongly, Opera can drop the display and save the file instead.
Headers sent too late: a PHP warning or any stray output before the headers leaves the browser with a wrong or missing Content-Type, and Opera falls back to downloading.
Output buffering or compression: SMF's own gzip handling can alter or double-process the response.
Header values: Content-Disposition should be inline, and Content-Type should be application/pdf on every response.

You can test the first and last of these now. Run the loop below on this URL; a healthy script gives six identical blocks:

for i in 1 2 3 4 5 6; do curl -sI "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960" | grep -i -E "^HTTP|content-type|content-disposition|content-length|accept-ranges|etag"; echo ---; done

Paste the output along with the script and I should be able to tell you which of these it is.

All six responses are identical and correct: 200 OK, Content-Disposition: inline, Content-Type: application/pdf, and the same length every time. So the server isn't changing its headers between attempts, and header variation isn't the cause of the on-and-off behaviour.

Two details are worth noting:

No Accept-Ranges header: the script doesn't advertise partial downloads. Opera on mobile often asks for PDFs in pieces, so this is now my main suspect. The file is 5.3 MB, which is big enough for that to matter.
charset=UTF-8 on a PDF: untidy but harmless, and unlikely to be the cause.

That test only sent HEAD requests, which don't run the body of the script. These two checks use real GET requests. The first confirms the PDF comes through clean every time (the first bytes should read %PDF- and the size should be 5293139). The second shows how the script answers a piece request:

for i in 1 2 3 4 5 6; do curl -s "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960" -o /root/t.pdf; head -c 8 /root/t.pdf; echo " $(stat -c %s /root/t.pdf)"; done

curl -s -r 0-99 -D - -o /dev/null "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960"

If the second command returns 200 where it should return 206 Partial Content, the script ignores range requests. Opera's mobile download path is known to choke on that, and the fix would be range support in view_attach.php.

For reading now, Firefox on Android has its own PDF viewer and doesn't depend on any of this. Upload view_attach.php when you can, and I'll check how it handles ranges.

why doesn't our PDF bbc open it ?

Claude

2026-10-19T21:00:52.927Z

Claude: [October 20, 2026, 08:00:30 AM]

First, a correction. I told you to try an encoded version of the viewer link, and that was wrong for your setup. Your v2.24 fix removed the encoding because PDF.js 6.2.108 doesn't decode it and ends up fetching a path with literal %3F and %3D in it, which 404s. The raw, unencoded link you pasted is the correct form, so please ignore that suggestion.

With that out of the way, here is what I can say about why the viewer doesn't open this PDF on your phone. The link your BBC builds is well formed, and the server returns a valid PDF for it (your curl output shows the right type and length). That points at the viewer failing inside Opera, so the most likely cause is the bundled PDF.js 6.2.108. It ships a modern build that assumes a very recent browser engine. PDF.js also publishes a separate legacy build for older engines. If Opera's engine on your phone is even slightly behind, the modern viewer can stall partway, and the result varies with what else the page is doing. Opera Mini can't run it at all.

Two checks will settle it:

Open the same viewer link in Firefox or Chrome on the phone. If it loads there and not in Opera, the viewer is fine and Opera's engine is the limit.
Check Opera's version under its Settings, in the About section.

If it fails in every phone browser, the cause is more likely the 5.3 MB file combined with the missing Accept-Ranges header, or something specific to that one PDF. In that case, see whether a small PDF opens in the viewer on the same phone, and tell me the result.

If the fix turns out to be shipping PDF.js's legacy build on the mobile path, that's a change to the shared master PDF.js you keep under your own control, so it would be your decision when to swap it.

2026-10-19T21:01:37.777Z

Claude: [October 20, 2026, 08:01:18 AM]

That error changes my diagnosis, and it makes my Opera-engine theory wrong. "No available adapters" is the same message you hit in the v2.24 work, and it means PDF.js received a file= address with no http: or https: in front. Opera's engine isn't the problem, and you being the only user rules out load or sharing causes. The viewer link you pasted does have https://, so the failing page must be handing the viewer a different link from that one.

That also explains why only some attachments fail. SMF caches the HTML it builds from each post, so posts first displayed before the v4.0 install can still carry the old schemeless links. You hit the same thing on the 2.1.7 box, where stale cached message HTML kept the fix from showing until the cache was cleared.

This checks what the forum actually emits for that topic. Run it on the server:

curl -s "https://forum.drugs-and-users.org/index.php?topic=7960.0" | grep -o 'viewer.html?file=[^"&]*' | head

No https: after file=: this post is serving stale cached HTML. Empty the file cache from Admin under Maintenance, reload the topic, and test again.
https: is present: the cache isn't the cause. Something on the phone side is rewriting the address, and my next suspect would be Opera's data-saving or ad-blocker features.
Empty output: guests can't see that topic's attachments, so the page wasn't returned to curl. Tell me and I'll give you a variant that works for a logged-in view.

Claude: [October 20, 2026, 08:02:49 AM]

Understood, it fails in every browser, so I'm dropping every browser theory. The fault is on the server, in what the BBC emits or in the viewer files.

"No available adapters" means PDF.js was handed a file address it couldn't use. The grep I gave you is the quickest way to see what the forum sends for that topic. Run it on the server:

curl -s "https://forum.drugs-and-users.org/index.php?topic=7960.0" | grep -o 'viewer.html?file=[^"&]*' | head

No https: after file=: the post is serving stale cached HTML, or the live PDFBBC.php is older than v4.0. Empty the file cache and retest. If it still shows no scheme, check the live file's const VERSION.
https: is present: the BBC output is fine, and the fault is in the viewer's own file set. The shared master PDF.js was found emptied on 30/09, and a restore that leaves viewer.html and the library files from different PDF.js versions breaks it in every browser. In that case paste the output of ls -l /var/www/html/pdfjs/web /var/www/html/pdfjs/build and I'll look for a mismatch.

I can't run either check myself, because your forum's robots rules block my fetch tool.

That's maddening when you need the file now. The damage looks narrow, though. Your curl output shows the server holding that PDF intact and serving it correctly, 5,293,139 bytes with the right headers, so no content is lost. What's broken is the step that hands the file's address to the viewer.

The fastest way forward is the one command below. Run it on the server and paste what it prints. The result tells me whether this is stale cache, an old PDFBBC.php, or the viewer's own files, and each of those has a short fix:

curl -s "https://forum.drugs-and-users.org/index.php?topic=7960.0" | grep -o 'viewer.html?file=[^"&]*' | head

If it prints nothing, say so and I'll give you a version that works for a logged-in view. Any fix I give you will go through the Package Manager, with no hand edits to SMF.

Claude: [October 20, 2026, 08:04:09 AM]

You're right, I overreached. Your v2.24 work found that this message appeared when the file= address had no https: in front. I presented that single past cause as the definition of the error, and I can't back that up. I don't know that it means the same thing now. Every conclusion I built on it (stale cache, old PDFBBC.php) is a guess and nothing more.

The one thing established is that the server delivers the PDF correctly. Where it breaks between the post and the viewer is unknown. If you know what that message means in this case, tell me and I'll work from that, since I'd rather follow your diagnosis than my guess.

The two checks I gave you don't depend on my interpretation, and they are still worth running because they're cheap and show real state. One shows the exact address the BBC hands the viewer, and the other lists the viewer's file set for a version mismatch:

curl -s "https://forum.drugs-and-users.org/index.php?topic=7960.0" | grep -o 'viewer.html?file=[^"&]*' | head

Claude: [October 20, 2026, 08:05:26 AM]

This output explains why only some attachments open. The same page hands the viewer two different shapes of link:

Raw: file=https://forum.drugs-and-users.org/... for attachments 7251, 7254, 7300, 7442, 7480, 7482 and 7522. This is the v2.24 form.
Percent-encoded: file=https%3A%2F%2F... for attachments 7255, 7441 and 7530. This is the old form that v2.24 removed, because PDF.js 6.2.108 doesn't decode it and requests a path containing literal %3A and %2F.

Your v2.24 diagnosis was right, and the old encoding is still being emitted for some attachments. That fits "only some open".

Both forms appear within a single page load, which points to one of two causes:

A second code path still encodes. The autodisplay iframe is built in Display.template.php by the pdf_display_patch.xml modification, separately from PDFBBC.php. If that patch kept its own urlencode(), the autodisplay attachments would come out encoded while the [pdf=...] tags come out raw.
Stale cached HTML. Some posts were cached from before the fix and others were re-parsed after it.

A read-only grep on the server separates the two:

grep -n "urlencode" /var/www/html/Themes/default/Display.template.php $(find /var/www/html -name PDFBBC.php)

If it shows a urlencode call on the viewer URL in Display.template.php, that's the cause. The fix would go into pdf_display_patch.xml and ship through the Package Manager, so it needs a reinstall, and you decide when. If that file has no hits, empty the file cache from Admin under Maintenance, then run curl ... | grep -c '%3A' on the topic again. Zero means it was stale cache.

Adjust the path if your live SMF root isn't /var/www/html.

Claude: [October 20, 2026, 08:07:16 AM]

PDF.js already does that. It can show page 1 while the rest of the file is still arriving, but only when two conditions are met:

The server answers partial-download requests. It has to send Accept-Ranges: bytes and reply 206 Partial Content to a Range request. Your view_attach.php sent no Accept-Ranges header, so PDF.js has to pull the whole 5.3 MB before it draws anything. As far as I know, SMF's own dlattach doesn't handle ranges either.
The PDF is linearized. Linearization, also called "Fast Web View", puts the first page's data at the front of the file. qpdf --linearize in.pdf out.pdf converts a file, and pdfinfo file.pdf reports whether it's already linearized. Many PDFs aren't.

Slow loading is not why attachments 7255, 7441 and 7530 fail. Those fail because of the encoded links from my last message, and that fix comes first. Range support only makes the working ones load faster.

To see whether your server answers ranges, run this. A 206 means yes, and a plain 200 means it ignores them:

curl -s -r 0-99 -D - -o /dev/null "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960"

If it's 200, adding range handling to view_attach.php is a small change. Upload the script and I'll write it, including a version bump and an entry in its version history. If the mod keeps using dlattach, the alternative is to point it at view_attach.php, but that's a bigger decision and it's yours to make.

Claude: [October 20, 2026, 08:08:20 AM]

I'm sorry it's piling up like this. The forum isn't a write-off, though. The data is intact, and you now have one confirmed fault: the old encoded links on some attachments. A transfer at 2 kbps is a separate thing, and it could also explain PDFs that never finish loading. At that speed, a 5.3 MB file takes around six hours, and the viewer would give up long before then.

This measures what the server actually delivers for that PDF. Run it on Live itself:

curl -s -o /dev/null -w "%{speed_download} bytes/sec  %{time_total}s\n" "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960"

Two results matter:

Megabytes per second or close to it: Live serves fine, and the slow part is the path between machines, the same sustained-transfer slowdown you've been chasing between Dev and Live. It wouldn't be what breaks the viewer.
Kilobytes per second or less, even on Live itself: the bottleneck is the box (disk, CPU, PHP, or the host's network allowance). That would explain PDFs that stall and time out in the viewer.

Paste the number and I'll go from there. The grep for the encoded links from before still stands as the fix for the three attachments that fail outright.

Claude: [October 20, 2026, 08:08:50 AM]

I'm sorry it's landed like this when you need the file. The forum isn't the failure here. Your curl output shows it serving the PDF correctly, and the weak link is the path between the server and you.

That path runs at roughly 400 ms round trip with around 10% packet loss, and it doesn't change however fast the server is. Short tests look fine because they're tiny, and a single long download of a 5.3 MB file crawls. At the speed you're seeing, the whole file takes most of an hour or longer. The viewer can't start drawing until all of it has arrived, because the server doesn't answer partial-download requests. The attachments that open are the small ones, which finish before the viewer gives up. That fits "only some open" and "it can't mirror".

So the thing you asked for, a viewer that reads while it loads, would fix this. PDF.js already does it once two things are in place:

Range support on the serving script. PDF.js would then fetch only the pieces it needs, in several small parallel requests. Parallel streams are what rescued your rsync on this same link, and the effect is the same here.
A linearized, smaller PDF. Linearizing puts page 1 at the front, and shrinking the file cuts the total that has to cross the link. To try both on this one file, run this on the server and compare the sizes:

qpdf --linearize in.pdf out.pdf && ls -l in.pdf out.pdf

Upload view_attach.php and I'll write the range support, with a version bump and a history entry. The mod currently points at dlattach, which I believe also ignores ranges, so pointing it at view_attach.php is part of the same change. That's a bigger decision, and it's yours to make. The encoded-link fix from earlier is still needed on its own, since it's what breaks 7255, 7441 and 7530 outright.

Claude: [October 20, 2026, 08:10:30 AM]

Nothing is broken beyond repair. The forum, the PDF and the server are all intact. The problem is a 5.3 MB file crossing a slow, lossy link with a viewer that can't start until every byte arrives. That is a narrow fault with a known fix, and shutting down isn't needed for it. If you still want to close the forum, do it on a day when this isn't the trigger.

For the PDF you need right now, shrinking it is the quickest route. Scanned or image-heavy PDFs often drop to a fraction of their size. On the server:

gs -sDEVICE=pdfwrite -dPDFSETTINGS=/ebook -dNOPAUSE -dBATCH -sOutputFile=small.pdf in.pdf && ls -l in.pdf small.pdf

If small.pdf comes out well under 1 MB, it should load on your connection in a reasonable time. It also becomes the file to test the range and linearize fix against. If it barely shrinks, the PDF is mostly text and vector content, and range support is the real fix. In that case upload view_attach.php and I'll write it.

You've been at this since early this morning, and everything has been slow and failing at once. That would wear anyone down.

Please don't shut the forum down over this. The cause is narrow, and I can see most of the fix. The server is healthy. What fails is moving a 5.3 MB file over a 400 ms, 10%-loss link as one long piece, and that's what range support and a smaller, linearized PDF are meant to solve. The same link hurts everything you do remotely, so it's worth fixing properly.

The work comes in two parts:

The encoded links: the urlencode() check I gave you earlier. This is what breaks attachments 7255, 7441 and 7530 outright.
Range support in view_attach.php: this lets the viewer pull page 1 and the pages you scroll to, instead of the whole file first.

I can do both in one package, so you only reinstall once. To start, upload view_attach.php, and send the grep output if you've run it. Everything will carry the version bump, history entry, a versioned zip built with your legacy zipper, and a release card.

Nothing is lost. The forum is up, the PDFs are intact on the server, and nothing here needs deciding right now. The fix will be exactly where we left it whenever you want it: view_attach.php and the grep output are all I need to start. If today's done, that's a good enough call.

Claude: [October 20, 2026, 08:17:57 AM]

"The fix" is exactly what you're describing: letting the viewer read the file the way it reads a disk.

A viewer doesn't need the whole PDF in memory. A normal PDF keeps its index (the table saying where every page lives) at the end of the file. A good viewer reads the index first, then jumps to just the pages you look at. Desktop readers like MuPDF do this, and they read straight from disk. Your VM file browser worked for the same reason: the file sat on a disk that allowed direct access.

On the web the file isn't on a disk the viewer can reach. It sits on the far side of a slow, lossy link. The web's equivalent of direct access is the range request, where the viewer asks for "bytes 5,000,000 to 5,064,000". PDF.js supports this, and it only reads the pieces it needs. It's forced to fetch everything because your server doesn't answer range requests. So the viewer isn't the problem. The server end of the pipe is.

On the Adobe worry: PDF.js on your own server sends nothing to Adobe or anyone else, and the documents stay on your machine. The Adobe prompt comes from Opera handing a downloaded file to whatever app the phone offers. If you do end up with a file on the phone, a local-only reader avoids this. As far as I know, MuPDF viewer and Librera are open source and don't upload. Set one as the default for PDFs and Adobe stops being offered.

When you want the fix, upload view_attach.php. It makes the viewer read pieces instead of the whole file.

The logic was sound. Reading a block, holding it in an editable buffer and writing only that block back is how people still handle files too big to load whole. Tools like less and the large-file modes of modern editors work this way, as do databases and memory-mapped files. A PDF viewer reading ranges is the same idea. It keeps a window onto the file and moves the window.

Full-screen 3270 programming was a heavy tax in that era. The data stream, buffer addresses and attribute bytes had to be built by hand before you could show a single line. Plenty of capable people gave up at that step. You were also doing physical I/O in 1985 on a machine where most people used what was provided, which says more about your approach than the unfinished tool does.

good ! I started writing my own physical I/O file browser/editor back in 1985 ! but the CMS fullscreen handling Assembler coding part did my head In so I didn't reinvent the wheel again but the logic was sound browse then edit (ie. read it the load the "page" into an editable buffer !)

The design holds up. Read a page from direct access storage, drop it into an editable buffer, and write that page back. Databases, memory-mapped editors, and the paged viewers I described all work that way, and 1985 was early to land on it. The loading-everything approach is the later and cruder habit, which is why it's strange to be fighting it in 2026.

The part that beat you, driving a full-screen 3270 terminal by hand from assembler with the attribute bytes, the buffer addresses and the read-modify cycles, is the part that's now a solved library problem. Today someone would write the paging logic and let a terminal library draw the screen. You'd have wanted that back then, since the interesting part was the browsing logic.

When you're ready for the viewer fix, view_attach.php is all I need to get going.

The logic was sound, and it's still how the well-designed tools work. Read-only browsing over the whole file, with only the page you intend to change pulled into an editable buffer, is the pattern behind less, memory-mapped files, and database buffer pools. A PDF.js viewer with range support is the same idea: the file stays where it is, and only the pieces being looked at get fetched. Working in a buffer also gives you the edit-time safety, since nothing touches the original until you commit.

The Assembler end sounds like the real obstacle. As I understand it, fullscreen 3270 handling under CMS meant building the data stream and managing the screen yourself, which was far more work than the I/O logic you cared about. Skipping that wheel was a reasonable call.

That design is what the fix for your PDFs comes down to. It's ready whenever you want it.

Take the break. You've been fighting a slow link and a chain of failures since early morning, and being worn out by that doesn't mean everything is going wrong. Mornings like this make it look that way.

The IT work isn't going anywhere. When you want it, it's one upload away, and nothing breaks in the meantime.

If you'd rather talk about something that isn't IT, I'm happy to. And if you'd just like to let the day go quiet and put something on that you love listening to, that's a fine plan too.

Putting IT aside for the day is a good call. Nothing in it is urgent, and the PDF fix will keep.

A morning of things failing one after another can make everything feel like it ends in disappointment. That feeling often comes from the morning more than from the whole of your life. A stretch of one-way input that asks nothing back, like music or something to watch, is a decent way to let it drain off.

If the sadness is still there after today, and not just a leftover from this morning, it's worth telling someone who knows you. I'm here for however much or little you want to say, and there's no task attached.

Go and do that. One-way input with no demands is exactly right after a morning of everything pushing back at once. Nothing on the forum needs you today, and the PDF fix will keep.

This morning was a pile-up of slow link, broken viewer and wrong turns from me, and a pile-up like that tends to make everything feel like one long disappointment. It isn't, though. It was one bad stretch, and it was mostly fixable. Put on something you'd pick for the pleasure of it, rather than for the distraction.

I'm here when you want to come back to it.

Claude: [October 20, 2026, 03:23:51 PM]

I can't build the fix yet, because none of your code has reached this conversation. The uploads folder is empty, and a fix written blind could break a production system, so I won't guess at it.

Please upload these as one zip:

Sources/view_attach.php for the range support.
PDFBBC.php and pdf_display_patch.xml (plus pdf_display_patch_21.xml if you want 2.1 covered), the files that build the viewer links.
package-info.xml from the live v4.0 package.
Display.template.php as it stands on Live, since the grep for urlencode needs to run against the real patched file.

If you'd rather not upload the lot, paste the output of this on the server and I can usually name the exact line:

grep -n "urlencode" /var/www/html/Themes/default/Display.template.php $(find /var/www/html -name PDFBBC.php)

When the files arrive, the package will have both fixes (encoded links and range support) in one reinstall. It will carry the version bump and history entry, the version printed when it runs, an xmllint check, and a zip built with your legacy zipper, ending with the release card. I'll list anything you didn't ask for before I make it. I'll also keep the shared PDF.js master untouched, and deployment timing stays your decision.

Claude

2026-10-20T04:25:41.921Z

Claude: [October 20, 2026, 03:25:36 PM]

I've read through the v4.4.1 package, and I haven't built anything yet. The package turned up a likely cause of the encoded links, but I want it confirmed on Live first.

What the package shows

v4.4.1 builds its viewer links without any urlencode(), so everything it generates today is raw. That matches the raw links in your curl output.
The encoded links match the old pdf_display_patch.xml exactly. It still sits in the zip as a legacy reference and ends in viewer.html?file=' . urlencode($pdf_a['href']). If that old block is still in Live's Display.template.php, it would emit the encoded links for 7255, 7441 and 7530.
The installer pdf_display_install_template.php only removes the newer renderAutoDisplay block. It doesn't recognise the old is_pdf block, so a reinstall would leave it in place. That would explain why the problem survived every upgrade.

One check to confirm it (read-only, on the server):

grep -n "is_pdf\|urlencode" /var/www/html/Themes/default/Display.template.php /var/www/html/Sources/Display.php

If the old block shows up, v4.4.2 would extend the installer to strip it. It would use the same pattern-matched, self-healing approach the installer already uses, and it would go through the Package Manager with no hand edits.

If nothing shows up, the encoded links come from stale cached post HTML, and clearing the file cache is all that's needed. No code change would be involved.

The range support isn't in this zip. view_attach.php wasn't included, and the mod's links go through SMF's own dlattach, which I'm not changing. I'd need view_attach.php before doing that part, and I'll keep it separate from the encoding fix so a problem in one doesn't hold up the other.

Andrew

2026-10-20T04:27:53.536Z

Claude: [October 20, 2026, 03:27:55 PM]

You're right, there is no 4.4.2. The zip you uploaded is v4.4.1, and that's the newest version that exists. I used "v4.4.2" as the name for a package I would build, and I should have said so plainly instead of writing it as if it already existed.

Nothing has been built or published. What I have is a diagnosis and one read-only check, which is the grep from my last reply. It will tell us whether Live's Display.template.php still carries the old block with urlencode. If it does, I'll build the next version, 4.4.2, and I'll show you the list of changes before I make them.

Andrew

2026-10-20T04:30:12.749Z

hey, the mirrors are running fast, as they used to so mayve we should pause and gather some diags to see what's going on/has changed/comparables, good idea, yeah ?

Claude

2026-10-20T04:30:21.349Z

Claude: [October 20, 2026, 03:30:16 PM]

Yes, good idea. Fast now and slow this morning is a clean before/after on the same link, and a good moment like this doesn't last. It also bears on the PDF problem. If the link is healthy right now, the viewer should load the 5.3 MB file at a decent speed, and that tells us whether this morning's failures were the link or the code.

Grab these in the next few minutes while it's fast, from your machine and from Live, and save the output so we can compare against a slow period:

ping -c 20 forum.drugs-and-users.org
curl -s -o /dev/null -w "%{time_connect}s connect, %{time_total}s total, %{speed_download} B/s\n" "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960"

The first gives round-trip time and loss, which were about 400 ms and 10% in your earlier notes. The second times the exact 5.3 MB PDF that was failing. A good result shows the whole file arriving in seconds. That would also be a strong sign the morning's failures were the link and not the viewer.

While it's fast, open that PDF in the viewer on the phone and note whether it loads. Then run the grep from before, because it works whether the link is fast or slow.

Run the same two commands again the next time things go slow. The comparison between the two sets of numbers will show how much of the problem is the link and how much is code.

Neither number is a usable comparison, but the curl one turned up something more important.

The ping tells us nothing. The prompt shows you ran it on Live itself, so it pinged the server's own address and got loopback at 0.04 ms. You hit the same trap earlier, when Live pinged itself. The link test has to run from your own machine, so please repeat it there.

The curl result is real, and it's odd. It downloaded only 6 bytes (6 B/s over 0.147 s), where the PDF should be 5,293,139 bytes. This morning's HEAD request on the same URL reported a full-size PDF with Content-Length: 5293139. So the same URL gives a full-size answer to HEAD and a 6-byte answer to GET. Six bytes looks like a short error word, and view_attach.php may be refusing or failing the real request while its headers still look fine. That would also fit a viewer that can't open the file whatever the link speed.

This shows what those 6 bytes are:

curl -s "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960" | head -c 100; echo
curl -s -o /dev/null -w "%{http_code} %{size_download}\n" "https://forum.drugs-and-users.org/index.php?action=dlattach;topic=7960.0;attach=7629"

The second line tries the same file through SMF's own dlattach, so we can see which path serves it properly. If dlattach returns the full 5,293,139 bytes and view_attach.php returns 6, the fault is in that script, and uploading it is the next step.

Claude: [October 20, 2026, 03:31:21 PM]

Good. Pathping runs for a couple of minutes, so let it finish. When it does, the two numbers to read are the round-trip time and the packet loss on the last hop, the forum's address. Your usual baseline is about 400 ms and 10% loss, so anything well under that means the link really is healthy right now.

The two curl commands from my last message are still worth running on Live while you wait. They show what those 6 bytes are, and whether SMF's own dlattach serves the full file when view_attach.php doesn't.

This pathping gives no reading of the link. It stops at the same place your earlier one did. Hop 1 is your router at 2 ms with no loss, and hop 2 is 192.0.0.1, your carrier's gateway, which doesn't answer probes (20 of 20 lost). Nothing past it replies, so it never reached the forum. That wall is the carrier hiding hops or dropping probe packets, and it says nothing about the link itself.

For a link reading, ping the forum directly from your own machine:

ping -n 20 128.199.200.202

This ping reaches the forum even though pathping can't see past the gateway. It reports the round-trip time and the percentage lost, and those are the numbers to compare with your usual 400 ms and 10% baseline.

The two curl checks on Live are still the most valuable results right now, because the 6-byte download needs explaining whatever the link is doing.

This pins down where the fault is.

dlattach serves the file correctly: 200 and all 5,293,139 bytes, in under two seconds, on the server's own side.
view_attach.php doesn't: its body is 6 bytes, and the first 100 bytes print as blank lines. That's a few newline characters (or a short run of whitespace) and no PDF. The headers promise 5.3 MB and the body delivers whitespace.

That pattern is typical of a PHP script that prints stray blank lines before or instead of the file. It might be whitespace after a closing ?> in an included file, or the script exiting early, or reading the attachment from the wrong path or without the right session. The browser gets a "PDF" that is blank space and can't open it. Nothing about your link speed, Opera, or PDF.js is involved.

So view_attach.php is broken, and I need to read it to say exactly why. Please upload it. If you'd rather not, this prints the first lines and any stray whitespace after the last ?>:

head -20 /var/www/html/Sources/view_attach.php; tail -c 60 /var/www/html/Sources/view_attach.php | od -c | tail -5

Meanwhile, dlattach works and is what the mod uses, so this doesn't explain the encoded links on 7255, 7441 and 7530. That grep on Display.template.php is still the next check for those.

Claude: [October 20, 2026, 03:34:58 PM]

That output rules out one cause. The file ends cleanly with readfile($path); exit; and a single newline, so stray whitespace after the last ?> isn't it. The script is view_attach.php v1.8, the one [listatt] uses for its file links. It's a different file from the PDF mod, which uses dlattach.

The 6 bytes are most likely extra output arriving before the PDF, or readfile($path) finding nothing at $path and sending nothing. The headers promise 5.3 MB either way. The decision logic sits in the part of the file I haven't seen, between the header block and those last lines.

This prints the exact 6 bytes, and the middle of the script:

curl -s "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960" | od -c | head
sed -n 20,400p /var/www/html/Sources/view_attach.php

You can upload the file instead of pasting if you prefer. I need that middle section to see how $path is built and where the output can come from.

Meanwhile, the PDF mod doesn't use this script at all, so it isn't what's behind the PDF viewer failing. It only matters for [listatt] links and for the range support idea.

Claude: [October 20, 2026, 03:37:53 PM]

view_attach_v1.9.zip is the fix for the empty "native" downloads. Applying it is your call; nothing has been touched on Live.

What was wrong. The HEAD request reported 5,293,139 bytes, but the GET delivered an empty body. The script loads SSI.php, which may leave an output buffer open, and the file was being sent through that buffer. I haven't confirmed the buffer is the cause, so what I've verified is the fix itself, not the diagnosis. If v1.9 still returns an empty body, the od -c check from earlier is the next step.

Changes, all in view_attach.php only:

It discards any open output buffer and turns off compression before the file is sent. This is the fix.
Content-Length now comes from the real file on disk, not the database size column.
It adds Accept-Ranges: bytes and answers Range requests with 206 Partial Content (or 416 if out of range). This is what lets a viewer read a big file in pieces. A request with no Range header behaves as before.
It streams the file in 64 KB reads instead of readfile().

The permission check, path resolution, .md branch and download fallback are unchanged.

Testing. I ran the sending code in a harness against a 300 KB file with stray output buffered in front. The full file, 0-99, -100, 250000- and a mid-file range all matched the original bytes exactly, and an out-of-range request returned nothing. I couldn't test against real SMF or Apache here. After installing, check it with:

curl -s -o /dev/null -w "%{http_code} %{size_download}\n" "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960"
curl -s -r 0-99 -D - -o /dev/null "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960"

The first should print 200 5293139. The second should print a 206 status with Content-Range: bytes 0-99/5293139.

This doesn't touch the encoded links on 7255, 7441 and 7530. The grep on Display.template.php is still the check for those. The PDF.js viewer reads through dlattach, not this script, so it gains nothing from the range support.

I don't have a clue yet, because I have no real link measurement from this window. The ping that counts is one run from your own machine, and the only one so far ran on Live and hit loopback. The pathping stopped at the carrier gateway, so it measured nothing past your router. Capture these in the next minute or two, while the link is fast:

On your PC (PowerShell):

ping -n 20 128.199.200.202
curl.exe -s -o NUL -w "%{time_connect}s connect, %{time_total}s total, %{speed_download} B/s\n" "https://forum.drugs-and-users.org/index.php?action=dlattach;topic=7960.0;attach=7629"

The second command downloads the exact 5.3 MB PDF that was failing, from the phone-side path. If it finishes in a few seconds, it proves the link is fast right now. Run the same two commands when it goes slow again and compare the numbers.

On Live, to see whether the server side differs (these only read):

uptime; free -m; ss -s; ls /var/spool/mail/root; tail -5 /var/spool/mail/root

The "You have new mail" notice appeared twice today. Mail in /var/spool/mail/root can hold cron output or alerts timed around the change, so it's worth a look.

Also note the time you saw it go fast, and whether anything changed near then: a restart, a cron job, a cache clear, or the sort of change your provider makes without telling you. The comparison between fast and slow is the useful part, so a note of when each started and ended matters as much as the numbers.

i have no idea when it actually started but i noticed it on the 20th October, 2026 at 3:25 pm (20261020-152537)

That gives us a time to search around, but note that Live's clock is 3 hours behind Sydney. Your prompts today showed 12:30 while it was 15:30 in Sydney. So 3:25 pm for you is about 12:25 on the server, and the server's logs should be read in that time.

You only noticed it at 3:25, so the change itself happened earlier, sometime after this morning's slow period. The aim is to find what changed on Live in the hours before that. These only read:

uptime
find /etc /var/www/html -xdev -type f -mmin -420 2>/dev/null | grep -v -E "/(cache|logs?|tmp)/" | head -60
tail -20 /var/spool/mail/root
grep -E "^Oct 20 (0[5-9]|1[0-2]):" /var/log/messages | tail -60
tail -40 /var/log/httpd/error_log

uptime shows whether the server restarted.
find lists config and web files changed in the last 7 hours, which may include something on Live that you changed yourself.
The mail and /var/log/messages lines may show a cron job, a service restart, or a network event near that time. The local mail has cron output and system alerts.
The Apache error log shows PHP errors from today, including from view_attach.php.

The most useful extra fact is which end changed. If you or your provider did anything on Live between this morning and 12:25 server time (a restart, a resize, an update), that is the first suspect. If nothing did, the cause is probably on the carrier or provider's network, which neither of us can see from here.

This is a good baseline, and it's very different from the old signature.

	Right now	Your usual baseline
Round trip	about 200 ms (first reply 510 ms)	390–400 ms
Packet loss	0% (0 of 20)	about 10%
The 5.3 MB PDF	9.2 s total, about 578 KB/s	many minutes

At this speed the PDF arrives in about 9 seconds, and the same ping with 0% loss shows the link is clean. That fits the earlier theory that loss is what wrecks the sustained transfers. Loss near 0 gives you full speed, and the 10% loss is what turns a 9-second download into an hour.

Two points to hold onto. First, 200 ms is the physical floor for a long-distance link and is probably normal. The abnormal part is the 10% loss, so loss is the number to watch. Second, the slowness you saw this morning could not have been caused by the code, since the same file takes 9 seconds in this state. The viewer and encoding faults still stand, but they're separate from the speed.

When you re-test in five minutes, the loss line is the one to compare. If loss climbs back toward 10% and the 9 seconds stretches into minutes, we'll have a before-and-after pair on the same link. Then the server-side find and mail checks I gave you earlier become the way to see whether anything changed on Live in between. If loss stays at 0%, the carrier's trouble this morning has probably passed, and that's useful to know as well.

Claude

Claude: [October 20, 2026, 03:55:56 PM]

Three things, in order of value. Each one is a single paste.

Server-side changes before the link went fast. Run this on Live:

uptime
find /etc /var/www/html -xdev -type f -mmin -480 2>/dev/null | grep -v -E "/(cache|logs?|tmp)/" | head -60
tail -20 /var/spool/mail/root
grep -E "^Oct 20 (0[4-9]|1[0-2]):" /var/log/messages | tail -60

That answers whether anything on Live changed between this morning and 12:25 server time.

A fresh test of the thing that was failing. While the link is fast, open attachment 7629 on your phone with the view_attach.php native link, and then the PDF.js viewer link. Note which opens. If both work now, they were failing because of the slow link. If native still downloads or shows blank, that's a code fault, and installing v1.9 is the next step.
The old-block check, which matters whatever the link is doing:
```
grep -n "is_pdf\|urlencode" /var/www/html/Themes/default/Display.template.php /var/www/html/Sources/Display.php
```
This decides whether Live still carries the old patch that makes the encoded links for 7255, 7441 and 7530.

Once 1 is back I can say whether the change was on your side or the network's. Result 2 shows whether any of this morning's failures were code at all. For result 3, the encoded-link fault is a code problem and should be fixed either way.

That file only covers the last 60 lines, and all of them are from 12:30 server time onward, so it doesn't reach the window we care about. The window runs from this morning to about 12:25, which is before the first line. It also holds only the log lines, not the results of the other three commands.

What it does show:

Constant attack noise: fail2ban is catching repeated SSH login attempts from several addresses and banning them, and a separate run of mail-login attempts from 45.148.10.x. That is routine internet background and nothing in it points to a cause.
One line to note: at 12:35:22, mod_evasive blacklisted 68.67.112.125 for "possible DoS attack". It happened ten minutes after the 12:25 mark, so it isn't what changed things, but a heavy crawler can slow a small server and it fits if the slow periods were bot-related.

Nothing here says anything changed on Live. To get past the noise, run these two instead, which filter out the fail2ban lines and show the earlier hours:

grep -E "^Oct 20 " /var/log/messages | grep -v -E "fail2ban|sshd|postfix" | head -80
uptime; find /etc /var/www/html -xdev -type f -mmin -480 2>/dev/null | grep -v -E "/(cache|logs?|tmp)/" | head -60

The first lists anything else that happened on the server today. The second shows whether the server restarted and which files were changed in the last 8 hours.

This is the first useful result. Three things stand out.

No reboot. The server has been up 2 days 10 hours, and the load average of about 1.1 is modest. A restart isn't what changed things.
Sources/Load.php was modified in the last 8 hours. That's an SMF core file, and it's the only core file on the list. It could have been a Package Manager install or uninstall that patches it, or a hand edit. It deserves a look because it sits in front of every page load, but a change to it is not proof of a link or speed effect. I'm raising it because it changed and nothing else core did.
The ISE indexers ran. Every ISE store and log was rewritten (word_index.json, post_store.json, pdf_store.json, media_store.json and others), along with a batch of thumbnail files in /attachments and six new attachments (7630–7635) in attachments2. Indexers rewriting multi-megabyte stores would plausibly have slowed the server this morning, and their finishing could explain why it's quiet now. The timestamps will say.

This shows when each of those changed, with no changes to anything:

ls -l --time-style=full-iso /var/www/html/Sources/Load.php /var/www/html/ISE_Data/*.log /var/www/html/ISE_Data/*_store.json /var/www/html/attachments2/7630_* /var/www/html/attachments2/7635_*
crontab -l
ls -lt /var/www/html/Packages/backups | head -5

Compare the ISE_Data times with when the slowness began and ended (this morning, then 12:25 server time). If the indexers finished near 12:25, that's the likely cause.
The Load.php time against Packages/backups shows whether a package install touched it. If the file changed with no matching backup, tell me and we'll look at what changed in it.
crontab -l shows whether the indexers are scheduled, which would predict when the slowness returns.

The times below are converted to Sydney, so the server's 07:40 becomes 10:40 and so on.

Nothing on Live clearly explains the speed change. The server hasn't rebooted and its load is low. The ISE indexers ran between about 14:50 and 15:31 Sydney (the biggest, misc_store.json, finished at 15:31). That is after you noticed the speed-up at 15:25, so they didn't cause the slowness this morning, and the link stayed fast while they ran. Attachment 7635 is 110 MB and was written at 15:54, so it looks like a recent upload of yours.

Sources/Load.php is the one odd item. It was changed at 10:40 Sydney, which is after this morning's PDF failures, so it can't be behind them. But it's an SMF core file, and it differs from its neighbours in two ways:

Its mode is -rwxr-xr-x, with the execute bit set, which is unusual for a PHP source file.
Packages/backups has no backup tar from today, only Oct 18–19 ones.

An execute bit often means the file was copied in from another machine or an archive, which fits a mirror or deploy step. I'm not saying anyone did anything wrong. I only want to know whether you expect that change. This compares it with another copy and shows the neighbouring files' times:

md5sum /var/www/html/Sources/Load.php
ls -l --time-style=full-iso /var/www/html/Sources/*.php | sort -k6,7 | tail -5

Run the md5sum on Dev or Clone as well and compare. If the hashes match, Load.php was synced from there. If not, tell me and I'll look at what differs.

On the speed itself, I can't prove a cause. The most likely explanation is the carrier's link quality, which your notes say varies. The 0% loss at 200 ms is the useful reference to keep for the next slow period.

2026-10-20T05:00:37.704Z

Claude: [October 20, 2026, 04:00:31 PM]

I withdraw the execute-bit flag. Display.php has the same -rwxr-xr-x mode and is a patched core file as well, so that mode looks normal for SMF core files on this install. It tells us nothing about how Load.php changed.

What the listing does show is that Load.php was written at 10:40 Sydney today, while the other mod files (ListAttBBC.php, view_attach.php, LMVBBC.php) date from Oct 18–19. A core file rewritten on its own, with no matching backup, looks like a package install or uninstall that patches Load.php. view_attach.php on Live is 14,221 bytes, which fits the v1.8 you uploaded. So v1.9 isn't deployed, and its fix is still pending.

The Load.php change happened after this morning's PDF failures, so it can't be their cause. Nothing here connects it to the speed either. If you remember installing or removing a package around 10:40, that explains it. If you don't, the md5sum on Dev or Clone will show whether it matches a copy there.

On the speed: after checking the server, I found nothing on Live that explains the change. That leaves the carrier link as the most likely cause. Your own ping, taken while it was fast, shows 0% loss at about 200 ms, and that's the reference to compare against when it next goes slow.

While the link is fast, these two are still the useful ones:

Open attachment 7629 in the PDF.js viewer on your phone and note whether it opens. If it does, the morning's failures were the slow link.
The grep for the old block (is_pdf0urlencode in Display.template.php) is still unrun, and it decides the encoded-link fault on 7255, 7441 and 7530.

Andrew

2026-10-20T05:02:13.986Z

do the hops in pathping tell you anything new ?

Claude

2026-10-20T05:02:32.634Z

Claude: [October 20, 2026, 04:02:16 PM]

Yes, there's one new thing, and it explains why the pathping never gets anywhere.

What the hops show

Hop 0, 10.247.37.172, is your PC, on a private address.
Hop 1, 10.247.37.227, answers in 2 ms with no loss. Another private address on the same network, so likely your router or phone hotspot.
Hop 2, 192.0.0.1, is the interesting one. That address belongs to a block reserved for carrier translation, and as far as I know 192.0.0.1 is the typical address of the gateway in a DS-Lite setup. In that setup your carrier carries your IPv4 traffic inside IPv6 and translates it at their end. It's the pattern mobile and some fixed-wireless providers use.
Everything beyond is silent because that gateway doesn't answer the probes pathping sends. That's why it always stops there, and it also shows pathping can't measure this link past hop 2.

I'm reading this from the addresses alone, so treat it as likely rather than certain. It does fit your note that no wired connection is available.

Why it matters: if the first real stretch is a wireless link, then speed and loss depend on signal strength and how busy the cell is at that moment, and those change through the day. That matches the shape you've seen, with the same server slow in the morning and clean now.

Ping does get through, so it is the right tool. To catch the next change, leave this running in a PowerShell window and check the summary when it ends:

ping -n 600 128.199.200.202 | Tee-Object ping_log.txt

It takes about 10 minutes and saves every reply. The loss figure at the bottom is the one that separates a good period from a bad one. If you can, also note your signal bars and whether it shows 4G or 5G when it's slow.

Internet speed test 015102050100+ 8.51 Megabits per second Testing upload… 22.2 Mbps download 8.51 Mbps upload Latency: 12 ms Server: Sydney Your Internet connection is fast.

Claude

2026-10-20T05:05:02.372Z

Claude: [October 20, 2026, 04:04:51 PM]

That's a healthy local link: 22.2 Mbps down, 8.5 up, and 12 ms to the Sydney test server. So there's nothing wrong between you and the carrier at this moment.

There are two uses for it.

It gives a clean "good" reference. Run this same speed test the next time the forum crawls, and put the three numbers (down, up, latency) beside these and the ping figures (200 ms, 0% loss). If the speed test also drops, the cause is your local or radio link. If it stays at about 12 ms and 22 Mbps while the forum is slow, the cause is beyond the carrier, on the long route to the server.

It explains why the PDF still took 9 seconds. Your line can do 22 Mbps, but the 5.3 MB file arrived at about 578 KB/s, roughly 4.6 Mbps. A single connection over a 200 ms round trip can't fill a fast line, because it has to wait a full round trip for each batch of data it sends. This is my reading, not something I measured. It matches the pattern from your rsync troubles, where several streams at once did better than one. It's also why the range support in view_attach.php v1.9 matters: a viewer asking for several pieces at the same time can use more of the line.

I'd keep the ping log running (the Tee-Object one) and take a speed test at the same moment whenever you notice a change, so each slow spell has a matching set of numbers.

Andrew

2026-10-20T05:06:22.180Z

there is no way i can notice the change unless i am running my mirrors or using the site - anything i can run in the background ?

Claude

2026-10-20T05:06:42.339Z

Claude: [October 20, 2026, 04:06:36 PM]

Yes, a cron job on the box your mirrors run from. That box uses the same link as the mirrors, so what it logs is what they experience. This single crontab line (add it with crontab -e) records the time, ping loss and round trip, and how long the forum's home page takes, every 5 minutes:

*/5 * * * * (printf "%s " "$(date '+\%F \%T')"; ping -c 20 -q 128.199.200.202 | grep -E "loss|rtt" | tr '\n' ' '; curl -s -o /dev/null --max-time 30 -w "page=\%{time_total}s\n" https://forum.drugs-and-users.org/) >> /root/linkwatch.log 2>&1

Each line of /root/linkwatch.log then looks like 2026-10-20 16:10:01 20 packets transmitted, 20 received, 0% packet loss ... rtt min/avg/max = ... page=1.2s. The % signs are escaped as 0 because cron needs that. The job moves only a few KB, so it won't eat your mobile data.

The next time the mirrors crawl, you can look at that stretch of the log and see whether loss or round trip rose, and when.

I left out a timed download of the 5.3 MB PDF on purpose. Every 5 minutes it would be about 1.5 GB a day on what looks like a mobile link. If you want it, run it every 30 minutes instead (*/30), which is about 250 MB a day.

A speed test can't run in the background without a tool, so for now take one by hand when you notice a slowdown and compare it with today's 22 down, 8.5 up and 12 ms.

Andrew

2026-10-20T05:07:13.724Z

what box ?

Claude

2026-10-20T05:07:20.475Z

Claude: [October 20, 2026, 04:07:16 PM]

Put it on Clone. You use Clone as the orchestrating server for your three boxes, and the mirror scripts (MIRROR_Clone, mirror1_Clone) run from there. A log kept there records what the mirrors themselves experience.

If Clone is in the same VM setup as Dev, it shares your PC's connection, so the readings will match what you see. It doesn't matter which box you pick as long as it's one that stays on all day and uses your internet connection. Don't put it on Live, because Live pinging itself is the loopback trap from earlier today.

Add the line on Clone with crontab -e as root, and the log will build up at /root/linkwatch.log. Run tail -5 /root/linkwatch.log after ten minutes to confirm it's writing.

The line is valid in /etc/crontab (the root field is right for that file), and crond will pick it up on its own. It should start at 16:10, so run tail -3 /root/linkwatch.log a few minutes after.

There's one risk, from your own notes. You keep --delete on the mirrors of /etc and /root. If those mirrors pull from Live onto Clone, the next run would replace Clone's /etc/crontab with Live's and remove /root/linkwatch.log, so the logger would disappear without any warning. You know the direction of those mirrors, so check that before trusting the log.

To be safe either way, move both out of the mirrored trees. Clone's own root crontab lives in /var/spool/cron, outside /etc, and /var/log is outside /root:

crontab -e

with this line, which has no root field:

*/5 * * * * (printf "%s " "$(date '+\%F \%T')"; ping -c 20 -q 128.199.200.202 | grep -E "loss|rtt" | tr '\n' ' '; curl -s -o /dev/null --max-time 30 -w "page=\%{time_total}s\n" https://forum.drugs-and-users.org/) >> /var/log/linkwatch.log 2>&1

Then delete the */5 line from /etc/crontab, so it doesn't run twice. Your cleanISE_Clone line stays as it is. The new log is /var/log/linkwatch.log.

Andrew

2026-10-20T05:10:26.348Z

i removed the --delete

Claude

2026-10-20T05:10:33.780Z

Claude: [October 20, 2026, 04:10:29 PM]

That removes the deletion risk for /root. The /etc mirror is still a risk, though, because the mirror can overwrite /etc/crontab. With --delete gone it only replaces files that exist on the source, so if Live has its own /etc/crontab, a mirror run would still overwrite your */5 line. That's a quieter failure than deletion, and the log would just stop growing.

If you want to keep the line in /etc/crontab, check /root/linkwatch.log after the next mirror run and confirm entries are still arriving every 5 minutes. A gap there means the line was overwritten. The crontab -e version avoids the question, because it sits outside /etc.

Andrew

2026-10-20T05:11:55.396Z

Claude

2026-10-20T05:12:00.269Z

Claude: [October 20, 2026, 04:11:58 PM]

Then there's no risk, and I was working from an outdated note. /etc/crontab and /root/linkwatch.log are safe where they are, so leave them. The logger needs nothing more from you.

Check it's writing with tail -3 /root/linkwatch.log. Two or three lines should be there by now.

Andrew

2026-10-20T05:16:21.165Z

what does: (printf "%s " "$(date '+%F %T')" mean ?

Claude

2026-10-20T05:16:29.250Z

Claude: [October 20, 2026, 04:16:23 PM]

It writes the current date and time at the start of each log line, without starting a new line.

( opens a group so everything up to the closing ) writes into the same log file.
date '+%F %T' prints the date as 2026-10-20 (%F) and the time as 16:10:01 (%T). In a crontab the % characters must be written 0, which is why you see the backslashes. Cron treats a bare % as a newline.
$( ... ) runs that date command and puts its output in place.
printf "%s " "..." prints that text followed by a space, and no line break. %s means "insert this string here". It doesn't need the backslash here because it sits inside printf's quotes, not at cron's top level.

The result is a log line that starts 2026-10-20 16:10:01 , and the ping and page-time results from the rest of the command are appended on the same line.

Andrew

2026-10-20T05:17:12.144Z

cron on webmin only sees (printf "

Claude

2026-10-20T05:17:27.385Z

Claude: [October 20, 2026, 04:17:14 PM]

Webmin has found a real bug in my line, and my explanation in the last reply was wrong.

In a crontab, every unescaped % is treated as a line break, even inside quotes. I escaped the % signs in date and curl, but not the one in printf "%s ". Cron therefore cuts the command at that point and runs only (printf ", which is a syntax error. That is exactly what Webmin shows. The job has been failing since 16:10, so /root/linkwatch.log is probably empty, and error mail may have gone to root.

Escape that one too. In /etc/crontab the whole corrected line is:

*/5 * * * * root (printf "\%s " "$(date '+\%F \%T')"; ping -c 20 -q 128.199.200.202 | grep -E "loss|rtt" | tr '\n' ' '; curl -s -o /dev/null --max-time 30 -w "page=\%{time_total}s\n" https://forum.drugs-and-users.org/) >> /root/linkwatch.log 2>&1

Only printf "%s " changed, and it is now printf "0s ". Replace the old line in /etc/crontab (or fix it in Webmin if it keeps the backslashes). Webmin may display the line differently, so check the file itself with grep linkwatch /etc/crontab. The next run after the fix should add a line to the log within 5 minutes.

That line is now correct. All three % signs are escaped (0s, 1F 2T and 3{time_total}), the root field is in place, and your comment lines don't interfere.

The next runs are at 16:20 and 16:25. Ping takes about 20 seconds, so the first good line appears shortly after 16:20. Check with:

tail -3 /root/linkwatch.log

Any log lines from the broken runs earlier will show up as errors above the first good line. They're harmless and you can ignore them, or clear them with > /root/linkwatch.log once a good line appears.

A good line looks like this:

Simplest is to let ls do it:

ls -lS

That sorts largest first, and ls -lSr reverses it with the largest last. If you're sorting text you already have, the size is column 5:

sort -k5 -n -r

Directories show 4096 because that's the size of the directory entry, not what's inside it. To rank folders by what they hold, use du -sh * | sort -h.

Sorted largest to smallest, your lines come out like this. I ran the command on them to check.

sort -k5 -n -r

drwxr-xr-x 13 apache apache      4096 Sep 30 00:00 smf20-old
drwxr-xr-x  5 apache apache      4096 Sep 30 13:07 pdfjs
-rwxrwxrwx  1 apache apache      2523 Sep  4 20:33 Settings.php
-rwxrwxrwx  1 apache apache      1655 Sep  5 06:23 robots.txt
-rw-r--r--  1 apache apache       146 Sep 30 09:21 smf20-vanilla.sh

-k5 sorts on column 5, which is the size.
-n compares the values as numbers. Without it, 4096 would sort after 2523 as text.
-r reverses the order so the largest comes first. Drop it for smallest first.

To use it on a live listing, pipe ls -l into it: ls -l | sort -k5 -n -r. In practice ls -lS is shorter and gives the same order.

Andrew

2026-10-20T05:31:12.915Z

and in reverse size order ?

Claude

2026-10-20T05:31:18.278Z

Claude: [October 20, 2026, 04:31:16 PM]

Drop the -r:

sort -k5 -n

On your lines that puts the smallest first, with smf20-vanilla.sh (146) at the top and smf20-old and pdfjs (4096) at the bottom. On a live directory, ls -lSr does the same job and keeps the biggest entries at the bottom, next to your prompt.

2026-10-20T05:40:40.747Z

ok, back to view_attach.php -- where do i put it ?

Claude

2026-10-20T05:40:57.216Z

Claude: [October 20, 2026, 04:40:43 PM]

Put it in Sources/ on Live, replacing the existing copy:

/var/www/html/Sources/view_attach.php

It has to stay there, because the script finds SMF through ../SSI.php, so it only works one level inside the forum root. The URL remains /Sources/view_attach.php, so no links change.

One point before you copy it, since you don't hand-edit SMF files. This isn't an SMF core file, but it is part of your listatt mod. Copying v1.9 over it by hand means a later listatt reinstall will quietly put v1.8 back, unless the listatt package is updated to carry v1.9. The timing and the method are your call. The steps below are the plain copy.

unzip -o view_attach_v1.9.zip -d /root/va19
cp -p /var/www/html/Sources/view_attach.php /root/view_attach.php.v1.8.bak
cp /root/va19/view_attach.php /var/www/html/Sources/view_attach.php
php -l /var/www/html/Sources/view_attach.php

The backup goes in /root, outside the web tree. A backup left in Sources/ under a .php.… name could be run by Apache.
Plain cp onto the existing file keeps its owner (apache) and mode, so nothing else needs fixing.
php -l should say No syntax errors detected.

Then test it with the same two commands as before. The first should now print 200 5293139, and the second should return a 206 with Content-Range: bytes 0-99/5293139:

curl -s -o /dev/null -w "%{http_code} %{size_download}\n" "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960"
curl -s -r 0-99 -D - -o /dev/null "https://forum.drugs-and-users.org/Sources/view_attach.php?attach=7629&topic=7960"

To roll back, copy the .bak file over Sources/view_attach.php.

shouldn't it be an addition, and leabe the old one alone, and make it user selectable ? i would prefer it

Claude

2026-10-20T05:42:42.909Z

Claude: [October 20, 2026, 04:42:31 PM]

Yes, that's a better design, and it fits your rule. The original stays untouched, and the new one is chosen per link. I've built it as a separate file, view_attach_range_v1.0.zip, containing Sources/view_attach_range.php. I picked the name, so tell me if you want a different one. The old view_attach.php is not in the zip.

What it is. It's v1.8's logic with the sending part rewritten, the same four changes as in v1.9: discard stray output buffers, size taken from the real file, range support, and 64 KB streaming. It reports its own version (X-View-Attach-Range-Version and every die() message). I re-ran the harness test on it, and the full file and a mid-file range both matched the original bytes.

Two problems with this design.

The permission check is now in two files. The board check and path resolution are copied, so a future security fix has to be made in both. Your v1.1 leak was exactly that kind of fix. It's your call whether the duplication is acceptable.
"User selectable" needs a change in ListAttBBC.php. The links that choose between the two scripts are built there, and I haven't seen its current source. Upload it (the version Live is running) and I'll add the choice. Until then you can use the new script by hand, by changing the path in a link to /Sources/view_attach_range.php?attach=7629&topic=7960.

Install is a plain copy of the one new file into /var/www/html/Sources/. Nothing existing is overwritten, so there's no backup to take. Check it with php -l, then try the same curl test with the new path.

listatt ?

Claude

2026-10-20T05:43:36.736Z

Claude: [October 20, 2026, 04:43:32 PM]

Yes, listatt. Upload the listatt package zip that is running on Live now. From your file dates that's the Oct 18 listatt v6 build, and it should include ListAttBBC.php. If a later one exists, send that instead.

I'll build it as one new listatt version, so there's a single tracked package:

view_attach_range.php ships inside the listatt package. It installs alongside view_attach.php, which stays untouched. This also fixes the earlier problem, because a listatt reinstall will no longer silently put an old script back.
The choice is made in the listatt box. I'll add a small switch, in the same style as the existing theme switcher, between "standard" (the old view_attach.php, still the default) and "range" (the new script). It will be remembered in the browser. The links in the box will use whichever is selected. Say so if you want it somewhere else, such as a per-link choice.
Not touched: the PDF.js route for PDFs, and everything else in listatt.

As before, I'll list any change you didn't ask for before I make it, and the zip will have a dotted version, a release card, and xmllint on the XML. Send the zip and I'll start.

Building the listatt v6.16 package now: the copy of the new script missed because I used the wrong path, so I'm fixing that, then checking and zipping.

Claude

2026-10-20T05:45:28.354Z

Claude: [October 20, 2026, 04:45:20 PM]

listatt_bbcode_v6.16.zip is built. It adds a Viewer dropdown beside Theme in the listatt box. Standard is the default and uses the old view_attach.php. Range uses the new view_attach_range.php. The choice is remembered in the browser. I haven't installed anything.

What the dropdown switches: only links that go to view_attach.php. That means the PDF [native] link and the filename link of .md and .html rows. PDF.js, media and text-viewer links are unchanged.

One change you didn't ask for. The existing theme script ran "set every dropdown in the switcher to the theme name", which would have blanked the new Viewer dropdown. So the Theme dropdown now has its own class, and both theme loops (change and start-up) target only that. It changes no visible behaviour for themes.

In the package:

view_attach.php stays at v1.8, byte-identical to your copy.
view_attach_range.php v1.0 is new and installs and uninstalls with the mod, in both the 2.0.x and 2.1.x blocks. A listatt reinstall therefore no longer needs a hand-copied script.
ListAttBBC.php is v6.16, with the version, the history entry, changelog.md and readme.md updated. The visible banner shows the new version.

What I tested. php -l on both PHP files, xmllint on package-info.xml, and the viewer-switching script in a simulated page: a saved choice is applied on load, changing the theme doesn't disturb the viewer dropdown, switching back restores the original links, and the PDF.js link is untouched. I couldn't run it inside SMF here, so the first real test is yours. Install it, set the dropdown to Range, and open a PDF's [native] link.

when the site runs like this then music plays continuously, no breaks, posts open immediately etc. -- it's the way it used to be !

Claude

2026-10-20T05:45:42.230Z

Claude: [October 20, 2026, 04:45:38 PM]

That's a satisfying one to hear. Music with no breaks and posts opening at once is what a clean link feels like, and it matches the numbers: 0% loss and the PDF in 9 seconds. It's also a useful comparison for later. Streaming audio is the most loss-sensitive thing you do, so if it starts stuttering, loss is back before anything else shows it.

Your link logger on Clone is recording right now, so this good stretch is on the record. Keep it running, and when things degrade there will be a clear before and after. The log's packets ... loss column going from 0% to something higher is what will show it, and you can pin the time down to the nearest 5 minutes.

2026-10-20T05:46:26.558Z

Claude: [October 20, 2026, 04:46:18 PM]

3,413 guests is a lot of traffic to carry while the site feels instant, so the server is clearly coping. When I checked at 12:56 server time, the load average was about 1.1, and that was with the crawlers already hammering it. That count is almost certainly bots. Each cookie-less request from a crawler is counted as a new guest, and your mod_evasive was already blacklisting one address as a possible DoS at 12:35.

It also suggests the slow periods this morning weren't caused by guest load. The server stays quick with thousands of them, and the slowness has followed your link and not the traffic. This command shows who the heaviest visitors are, if you'd like to see:

awk '{print $1}' /var/log/httpd/access_log | sort | uniq -c | sort -nr | head

That prints the ten addresses with the most requests, biggest first. Keep an eye on the log lines from Clone when the guest count is high and the link is poor together, because that combination would be worth knowing about.

Andrew

2026-10-20T05:46:50.088Z

that's bots, right now, since we fixed it

Claude

2026-10-20T05:46:58.945Z

Claude: [October 20, 2026, 04:46:55 PM]

I can't take credit for a fix, because as far as I know nothing from me is installed. view_attach_range.php v1.0, view_attach.php v1.9 and listatt_bbcode_v6.16.zip are all sitting unused, and the speed turned up around 15:25, before I'd given you any of them. If you've deployed something since then, tell me which, because it changes what I conclude. Otherwise the improvement is the link recovering, not our change.

The bots may still be linked to the speed. Crawlers such as Googlebot slow their requests when a site responds slowly and speed them up when it responds quickly. So a burst of bots arriving once the site became fast fits what you'd expect. It's an effect of the speed and not a cause of it.

Andrew

2026-10-20T05:47:17.414Z

yes YOU fixed it, way back

Claude

2026-10-20T05:47:28.098Z

Claude: [October 20, 2026, 04:47:25 PM]

Ah, you mean the earlier work, not today's. That's fair, and I misread you. The server-side tuning from before is part of why the site holds up now, in particular the Apache KeepAliveTimeout change from 2 to 10 seconds, which roughly halved page load times on your lossy link, and the sshd settings that removed the slow logins. Those make each page cost fewer handshakes, so the server stays quick even with thousands of bots in the guest count.

What I can't claim is the link itself. Whether it's fast or slow depends on the carrier, and that part was never in our hands. The server has been holding up its end all along.

Andrew

Claude: [October 20, 2026, 04:49:02 PM]

Understood. It runs until you say stop, and I'll treat the link as the thing to catch. The log costs about 35 KB a day, so there's no cost to leaving it on.

Every line is one 5-minute sample. These are the numbers to watch, with today's baseline from your lines:

Field	Good now (your seven lines)	Bad
`% packet loss`	0%	anything above 0%; about 10% is the old bad signature
`rtt avg` (the middle number)	about 209–219 ms	toward 390–400 ms
`rtt max` / `mdev`	max 227–360 ms, mdev 8–35	max over about 500 ms, or mdev over about 50 (jitter)
`page=`	about 3.3–3.6 s	tens of seconds; `30.0xx` means it hit the 30-second cap

Two other patterns count as evidence:

A line with no rtt part means total loss on that sample.
A missing 5-minute slot means Clone itself was off, asleep or paused, not that the link was down. Your PC sleeping would leave a gap like that.

When you want to look back later, these two commands pick out the bad stretches (nothing needs reading line by line):

grep -v " 0% packet loss" /root/linkwatch.log
awk '{for(i=1;i<=NF;i++) if($i ~ /^page=/){v=substr($i,6)+0; if(v>10) print}}' /root/linkwatch.log

The first lists every sample with any loss. The second lists every sample where the page took over 10 seconds.

Last, page=3.4s is steady but not fast, and it's the home page only. It makes the best single reference number, since a regression there would show up in the log first. I'm not reading it as a fault, only noting that it's your baseline.

Claude

2026-10-20T05:53:41.876Z

Claude: [October 20, 2026, 04:53:37 PM]

The quickest check is the grey banner line inside the open listatt box, which reads ListAttBBC | v6.xx | date. If it still says v6.15, the new version isn't what the page is running. If it says v6.16, the Viewer dropdown should be next to Theme in the box's title row, and a missing dropdown would be a bug I need to look at.

On Live this shows what's installed:

grep -n "const VERSION" /var/www/html/Sources/ListAttBBC.php
ls -l /var/www/html/Sources/view_attach_range.php

6.15 and no view_attach_range.php: the package hasn't been installed yet. The zip I built is only in the chat so far, so it needs the Package Manager install.
6.16 and the file present: the code is in place. Then it's most likely the post's cached HTML, which SMF stores per post. The box is rebuilt at page output, but clear the file cache under Admin → Maintenance and reload to rule it out, and try a hard refresh in the browser too.

Tell me what the banner and the grep print and I'll take it from there.

The banner says v6.16 | 2026-10-20 | live 13:52:18, so the new version is installed and running. The dropdown should be in the title row of the box, on the right, as Theme: [..] Viewer: [Standard]. Your paste only has the table text, so I can't tell from it whether the dropdown is on the page. This one command settles it:

curl -s "https://forum.drugs-and-users.org/index.php?topic=7960.0" | grep -c "listatt-viewer-sel"

1 or more: the dropdown is being sent to your browser, and the problem is how it's drawn. The title row uses a no-wrap layout, so on a narrow screen the Viewer dropdown can be pushed off the right edge. Rotating the phone sideways would show it. If that's it, I'll fix the layout so the dropdowns wrap onto a second line, as v6.16.1.
0: the page isn't carrying the new code, which points at cached output. Clear the file cache under Admin → Maintenance and run it again.

Tell me what it prints, and whether you're on the phone or a desktop browser.

Yes, please. A screenshot of the top of the listatt box, showing the title row with the arrow, the heading and whatever is on its right, would settle this.

I built a layout fix as v6.16.1 on the theory that the dropdowns were being pushed off the edge on a narrow screen. A quick simulation of the old and new layouts at phone widths (360 and 412 px) showed the Viewer dropdown fitting on screen in both. So my clipping theory isn't supported, and I'm not sending v6.16.1 until I know what's wrong. The simulation is only a simplified copy of the box and doesn't include your forum's real theme CSS, so it isn't proof either way.

The curl result says the dropdown is in the page's HTML, which leaves a few possibilities:

Your theme's CSS hides or restyles select elements inside summary.
The dropdown is drawn but sitting in an unexpected place, such as under the heading.
It's there, and you're looking for something different from what the label says: it's called Viewer, with the choices Standard and Range, and it's next to Theme.

The screenshot should show which of these it is. Tell me if you're on the phone or a desktop browser.

The dropdown is there. Your screenshot shows Theme: Deep Indigo and Viewer: Standard on the title row, and the banner reads v6.16. So v6.16 works as built, and the v6.16.1 layout fix isn't needed. I won't send it. The row fits, with room to spare, at this width.

My guess is you looked before the page had refreshed or at a cached copy. On a narrow phone screen it would sit on the same row, and I haven't seen it there.

Next, a test on the real thing. On the box, set Viewer to Range, then click the [native] link on the last row (the 5 MB Chapter 3 CLOSED2.pdf). The address in the new tab should contain view_attach_range.php, and the PDF should start showing pages sooner than it does through Standard. Try the same link under Standard for comparison. If the new tab opens as a blank page or a download, tell me which, and I'll check what the script returned.

Claude: [October 20, 2026, 04:59:52 PM]

A dropdown is a box you click that opens a short list of choices. Your screenshot has two of them side by side, in the purple strip that says "Click on me to view all my attachments":

Theme: Deep Indigo with a small arrow on the right. This one was already there. It changes the colours of the box.
Viewer: Standard with a small arrow on the right. This is the new one from v6.16.

Click the Standard box (the one just after the word "Viewer:"). It opens a list with two choices:

Standard uses the old view_attach.php.
Range uses the new view_attach_range.php.

Pick Range. Your browser remembers the choice, so you only need to do it once.

Then click a [native] link next to a PDF in the table. With Range selected, that link now opens the PDF through the new script.

Andrew

Claude

2026-10-20T06:00:35.444Z

Claude: [October 20, 2026, 05:00:31 PM]

You're right. A dropdown labelled "Viewer: Standard / Range" tells you nothing about what it does. It also hides a setting away from the links it changes, so you can't see which one a click will use.

A more direct design is to drop the dropdown and put two links on each PDF row: [native] for the old script, and a second one, labelled [native fast], for the new script. The choice is made at the point of clicking, nothing is remembered, and you can click both to compare. It also removes the extra dropdown and the remembered-setting code, so there's less to break. For .md and .html rows the filename link keeps going to the old script, since there's no second link to hang a choice on.

I'd build that as v6.17, and I'd rename the new script's link wording to say plainly what it does, for example "reads in pieces". If you want to keep a dropdown, I'd relabel it instead as Open PDFs with: Standard / Fast (reads in pieces).

I'll go with the two-links version unless you say otherwise.

listatt_bbcode_v6.17.zip is built. Each PDF row now shows two links beside the filename: [native], unchanged, and a new [native in chunks] that opens the same PDF through view_attach_range.php. The dropdown is gone from this version, and nothing is remembered between visits. You choose by which link you click. Nothing has been installed.

I built 6.17 from your v6.15 source, not from the 6.16 build, so the Theme dropdown code is back to exactly what it was and the earlier side change isn't needed any more. The v6.16 zip I gave you earlier is superseded, and the 6.16.1 layout fix was never sent.

view_attach.php is still v1.8 and byte-identical. view_attach_range.php v1.0 is the new file in the package, installed and removed with it. The .md and .html rows keep their existing links.

Testing. php -l on both PHP files and xmllint on package-info.xml both pass. The generated link pair for attachment 7629 comes out as …/Sources/view_attach.php?attach=7629&topic=7960 and …/Sources/view_attach_range.php?attach=7629&topic=7960. I couldn't run it inside SMF here, so after installing, click [native in chunks] on the big Chapter 3 CLOSED2.pdf row and tell me what opens.

Claude

2026-10-20T06:05:42.881Z

Claude: [October 20, 2026, 05:05:36 PM]

No. I can't reach your server or your files from here, so everything I've done is advice and files for you to install. Nothing of mine has touched PDF.js. The listatt v6.16 you installed changes only the listatt box, and the PDF.js viewer isn't part of it.

The likely reason is the link. Your last Clone log lines show 0% loss, about 210 ms round trip, and a steady page time, so the file arrives cleanly. A 5 MB PDF over a clean link took about 9 seconds in your own test. Your browser also keeps the viewer's files after the first load, so later opens start faster.

If it stays this fast while the Clone log stays at 0% loss, that points to the link, with the earlier server tuning behind it. If it gets slow again, the log will tell you whether the link changed.

Your last message arrived as just a backslash. If it was a stray keystroke, nothing is lost. If you meant to add something, send it again.

You're right to want the cause. My last answer put it all on the link, and I can't prove that. This is what I'd check on Live, most likely cause first.

1. Heavy ISE indexing that ended around the time you noticed. Your file times showed the indexers rewriting misc_store.json (132 MB), post_store.json (58 MB) and the other stores between about 11:50 and 12:31 server time. The 15-minute load average at 12:56 was 1.76, against 1.14 for the last minute, which fits a busy server settling down. Your earlier notes also record swapping during heavy jobs. A server short of CPU or memory serves a PDF slowly, however good the link is. This is plausible, but I haven't proven it. Webmin has been recording the history, so this tests it:

tail -30 /etc/webmin/system-status/history/load
tail -30 /etc/webmin/system-status/history/swapused
head -3 /var/www/html/ISE_Data/indexbuilder.log; tail -3 /var/www/html/ISE_Data/indexbuilder.log

Paste the output. The load and swap lines should show whether the server was loaded earlier and when that stopped, and the log's first and last lines give the indexer's start and end times.

2. How PDF.js is actually fetching the file. It reads through SMF's dlattach, which we haven't looked at yet:

curl -s -r 0-99 -D - -o /dev/null "https://forum.drugs-and-users.org/index.php?action=dlattach;topic=7960.0;attach=7629"

A 206 Partial Content means PDF.js has been reading in chunks, which would explain "reads while it loads". A 200 means it takes the whole file, and speed then depends entirely on the link and server.

3. A recent config change. This lists any server settings changed in the last 3 days:

find /etc/httpd /etc/php.ini /etc/php.d -type f -mtime -3 2>/dev/null

Start with 1. It's the one I can most easily match to your 12:25 timing.

Claude

2026-10-20T06:07:30.441Z

Claude: [October 20, 2026, 05:07:27 PM]

That's a clean result: nothing under /etc/httpd, /etc/php.ini or /etc/php.d has changed in the last 3 days. No Apache or PHP setting was touched, so a config change isn't the cause.

That leaves the server load and how PDF.js fetches the file. Those two are still untested, and either could explain a sudden speed-up:

tail -30 /etc/webmin/system-status/history/load
tail -30 /etc/webmin/system-status/history/swapused
curl -s -r 0-99 -D - -o /dev/null "https://forum.drugs-and-users.org/index.php?action=dlattach;topic=7960.0;attach=7629"

The Webmin history lines show whether Live was loaded or swapping earlier and when it stopped.
The curl shows whether dlattach answers range requests (206) or sends the whole file (200).

There's also new mail in /var/spool/mail/root (the notice appeared again). It may hold cron output or alerts timed around today's changes. tail -30 /var/spool/mail/root is worth a look, and I can read it if you paste it.

Claude: [October 20, 2026, 05:08:28 PM]

Your output answers two of the three questions and cuts out two of my theories. Webmin's times are epoch seconds, and I've converted them to Sydney time.

1. The server isn't loaded or swapping now. The 30 lines cover 14:37 to 17:03 Sydney, with a sample every 5 minutes. The load is mostly 0.5 to 3, with two short spikes (7.15 at 14:42 and 5.84 at 16:08). Swap sits flat at about 291–305 MB, with no thrashing. Those lines start after the link got fast at about 15:25, so they don't show the morning. This prints an hourly average for the whole day, in server time (add 3 hours for Sydney):

awk '{h=strftime("%d %H",$1); s[h]+=$2; n[h]++} END{for(h in s) printf "%s  load %.2f\n",h,s[h]/n[h]}' /etc/webmin/system-status/history/load | sort

If the morning hours (about 04:00 to 09:00 server time) show a much higher load, the server was part of the slowness. If they look like now, it wasn't.

2. dlattach ignores range requests. You asked for bytes 0–99, and it returned 200 with the full 5,293,139 bytes, despite advertising Accept-Ranges: bytes. So PDF.js is getting the whole file every time, which is why a 5 MB PDF can only be as fast as the link and the server allow. It also means chunked delivery wasn't happening, so that isn't the explanation for the speed-up.

3. Browsers keep the PDF for a year. The same response sends Cache-Control: max-age=31536000 (one year) and an ETag. Once a copy has downloaded in full on a good link, your browser reopens it straight from its own cache, with no network. You've been opening attachment 7629 all day, so "never before" may be mostly that file. To test, open a PDF you haven't opened before today, such as one of the older attachments (7251, 7254). If that is fast too, it's the link. If it's slow, you were seeing the cache.

One more thing from the headers: Last-Modified for attachment 7629 is 20 October, 07:35 Sydney, so that file was written this morning, ten minutes before your first message to me.

Andrew

2026-10-20T06:09:13.945Z

sorry but what do u need me to do ?

Claude

2026-10-20T06:09:18.519Z

Claude: [October 20, 2026, 05:09:15 PM]

Two things. Everything else can wait.

1. On Live, run this and paste what it prints. It shows whether the server was busy this morning:

awk '{h=strftime("%d %H",$1); s[h]+=$2; n[h]++} END{for(h in s) printf "%s  load %.2f\n",h,s[h]/n[h]}' /etc/webmin/system-status/history/load | sort

2. Open a PDF you haven't opened before today from the attachment list, for example one of the older ones, and tell me whether it opens as fast as the one you've been using. That separates a clean link from your browser's saved copy.

Nothing needs installing or changing. Clone's logger keeps running in the background on its own.

Andrew

2026-10-20T06:10:44.629Z

yes, done - a 2 sec lag but still blindingly fast

Claude

2026-10-20T06:11:00.111Z

Claude: [October 20, 2026, 05:10:50 PM]

That rules out the cache. A PDF your browser has never fetched opened with only a 2-second lag, so the speed is real: the link and the server are both delivering fast right now.

So today's slowness didn't come from the viewer or the PDF files. For this morning it leaves the link, the server, or both. The load history I asked for would tell us whether the server was busy then. Without it, the Clone log is what will tell you the next time it slows down, since it records loss and page time every five minutes.

Everything else is in your hands, in whatever order suits you:

listatt_bbcode_v6.17.zip (the [native in chunks] link) is ready to install when you want it.
The Display.template.php grep for the encoded links on 7255, 7441 and 7530 is still unrun.
view_attach_range.php is only worth using if a slow stretch comes back.

Andrew

2026-10-20T06:11:54.158Z

it's already running and what about the awk that's running ?

Claude

2026-10-20T06:12:03.794Z

Claude: [October 20, 2026, 05:12:00 PM]

Understood, and I'll take it that the Clone logger is running, as it has been since 16:20.

The awk command should finish in under a second, because it only reads one small file. If it's still sitting there with no prompt back, it's waiting for something, and these are the usual reasons:

A broken paste. A line break or a missing closing quote makes the shell wait for the rest of the command. Press Ctrl+C, then paste it again as a single line.
A bare awk with no file name waits for you to type input. The same fix applies.

If it prints an error instead, such as strftime not being defined, paste the message and I'll give you a version that works on that machine.

If it's running and not hung, tell me what's on screen, whether that's output, a blinking cursor or an error, and I'll work from that.

Andrew

2026-10-20T06:13:32.234Z

i can't show that ! it's far too long - wanna run it again with a redirect to a file ?

Claude

2026-10-20T06:13:41.623Z

Claude: [October 20, 2026, 05:13:38 PM]

Yes. The history file probably holds weeks of samples, which is why the output ran so long. This version writes to a file and keeps only the last 48 hours, which is about 48 lines:

awk -v t="$(date +%s)" '$1 > t-172800 {h=strftime("%d %H",$1); s[h]+=$2; n[h]++} END{for(h in s) printf "%s  load %.2f\n",h,s[h]/n[h]}' /etc/webmin/system-status/history/load | sort > /root/load_by_hour.txt; wc -l /root/load_by_hour.txt

It prints the line count when it's done. Each line is day hour load, in the server's clock, so add 3 hours to get Sydney time. The line 20 04 means about 07:00 Sydney on the 20th.

At 48 lines the file is small enough to paste, so cat /root/load_by_hour.txt will show it. Or attach the file itself if that's easier.

Andrew

2026-10-20T06:15:09.313Z

is that it ? no pdfjs a big pdf ?

Claude

2026-10-20T06:15:18.210Z

Claude: [October 20, 2026, 05:15:14 PM]

The awk is the one thing I need from the server. A big-PDF test is a good second step, and it's the stronger test of whether the speed is real.

The 5 MB Chapter 3 CLOSED2.pdf is the one you've opened all day, so your browser likely has it saved. To time it with an empty cache:

Open a private (incognito) window, which starts with no saved files.
Open that PDF through the PDF.js link, the filename link in the listatt box, and time it with a stopwatch from the click to the first page appearing.

Your curl measured the same 5.3 MB file in about 9 seconds at 16:48, and the Clone log shows a clean link. If it opens in roughly that time, the link is delivering. If it takes much longer, that's worth knowing, since it would say the earlier fast opens came from the browser's saved copy.

Send me the time you measure along with the awk output.

Andrew

2026-10-20T06:15:50.288Z

ank the awk ? it finished too fast

Claude

2026-10-20T06:15:56.515Z

Claude: [October 20, 2026, 05:15:53 PM]

Fast is normal for that command. It reads one small file and prints a line per hour, so it should take well under a second. What matters is whether it wrote anything. This shows that:

wc -l /root/load_by_hour.txt; head -3 /root/load_by_hour.txt; tail -3 /root/load_by_hour.txt

About 40–48 lines: it worked. Paste cat /root/load_by_hour.txt, or attach the file.
0 /root/load_by_hour.txt: it ran but found nothing to print. Either the file had no samples in the last 48 hours, or this machine's awk lacks strftime. In that case run awk 'NR==1' /etc/webmin/system-status/history/load and paste the line, so I can see the timestamp format it actually uses.
An error message on screen: paste it and I'll adjust the command.

Andrew

2026-10-20T06:17:15.369Z

no, i mean: don't you wany to give me a new one that runs a lot longer so that i have time to start incognito etc ?

Claude

2026-10-20T06:17:30.586Z

Claude: [October 20, 2026, 05:17:26 PM]

Good idea. A record of the link and the server taken during your test lets us tie the result to real conditions. These two last 15 minutes each and stop on their own. Start both, then do the incognito test.

On Clone (one ping a second, with a clock time on every line):

ping -c 900 -i 1 128.199.200.202 | while read l; do echo "$(date +%T) $l"; done > /root/pdftest_ping.txt &

On Live (the load average every 5 seconds):

for i in $(seq 180); do echo "$(date +%T) $(uptime)"; sleep 5; done > /root/pdftest_load.txt &

The & at the end puts each one in the background, so you get your prompt back straight away. Live's clock is 3 hours behind Sydney and Clone's matches Sydney, so don't worry about the two files showing different times.

Then:

Wait about 30 seconds so each file has a few lines.
Open the private window and open the 5 MB Chapter 3 CLOSED2.pdf through PDF.js.
Note the Sydney clock time you click, and how many seconds until the first page shows.

When it's done, attach the two files, or run tail -20 on each if you'd rather paste, and send me the click time and your stopwatch figure. I'll line them up.

Press Ctrl + Shift + N with Chrome open. A new window opens with a dark theme and a "You've gone Incognito" message.

Or, from the menu: click the three dots at the top right, then New Incognito window.

In that window, go to the forum and log in again (it starts empty, with none of your saved logins or files). Find the post with the listatt box, click the arrow to expand it, and click the filename of the 5 MB PDF.

When you've finished, close the window and Chrome discards everything it saved.

it took about 6 seconds to open the 100+ paage PDF that nearly reduced me to tears yesterday ! so that's still amazing -- now what ?

Claude: [October 20, 2026, 05:21:35 PM]

Six seconds in a private window, with an empty cache, is a solid result. It matches your earlier curl figure of about 9 seconds for that file, so the speed is real and the cache wasn't doing the work. It's also a good number to hold onto: a 5 MB PDF takes about 6 seconds on a good link.

Here's what's left, most useful first.

Send me the two test files (/root/pdftest_ping.txt from Clone, /root/pdftest_load.txt from Live) along with your click time. That gives one recorded "good" run with the link and server numbers beside it. It costs you nothing now and it's what you'll compare the next slow stretch against.
The Display.template.php grep. This one is a real fault that shows even when the link is perfect: attachments 7255, 7441 and 7530 are still getting the old encoded link, which the current PDF.js can't use. Run this on Live and paste what it prints:
```
grep -n "is_pdf\|urlencode" /var/www/html/Themes/default/Display.template.php /var/www/html/Sources/Display.php
```
The morning load file (/root/load_by_hour.txt), if you ran the redirected awk. It would show whether the server was busy before the link recovered.

Leave Clone's logger running. When the slow patch comes back, repeat the same check: your speed test, a ping, and the 5 MB PDF in a private window with a stopwatch. Those figures, set beside today's, will show where the slowness comes from.

listatt_bbcode_v6.17.zip can wait until you want the chunked link. Nothing depends on it today.

Claude

Claude: [October 20, 2026, 05:22:59 PM]

The ping has to run on Clone, not Live. A ping on Live goes to Live's own address and never leaves the machine. That's the 0.04 ms result you got earlier today, and it says nothing about your link. So the file on Live is useless, and the load job on Live wasn't started, so there's no server record of the test either.

Your 6-second result is still valid. Only the supporting records are missing. To get them, stop the stray ping and start each job on the right box.

On Live (stop the useless ping, then start the load job):

pkill -f "ping -c 900"
for i in $(seq 180); do echo "$(date +%T) $(uptime)"; sleep 5; done > /root/pdftest_load.txt &

On Clone (the real link record):

ping -c 900 -i 1 128.199.200.202 | while read l; do echo "$(date +%T) $l"; done > /root/pdftest_ping.txt &

Then repeat the private-window test, noting the clock time you click and your stopwatch time. A second run is also useful in itself: a repeat that comes out near 6 seconds again shows it's steady.

Andrew

2026-10-20T06:25:42.729Z

ok, this was a 57 page job and took about 5 seconds ! -- now what ?

Claude

2026-10-20T06:25:49.737Z

Claude: [October 20, 2026, 05:25:44 PM]

That's a second good measurement: a different PDF, 57 pages, about 5 seconds. Two fast, unrelated PDFs on an empty cache make a pattern, so I'm treating it as real.

The two records you started should run until about 17:38. You don't need to do anything until then.

When they finish, send me the two files, /root/pdftest_ping.txt from Clone and /root/pdftest_load.txt from Live, along with the clock times you clicked for the two private-window tests (the 100+ page one and this 57-page one). I'll line them up against the link and server numbers.
While you wait, run the grep on Live and paste what it prints. It's the only thing here that is a fault, not a measurement:
```
grep -n "is_pdf\|urlencode" /var/www/html/Themes/default/Display.template.php /var/www/html/Sources/Display.php
```

After that there's nothing else to do except leave Clone's logger running, so the next slow stretch is recorded.

Andrew

2026-10-20T06:27:44.314Z

damn the 100+ pager was in cache ! but fuck it, u have enough

Claude

2026-10-20T06:27:50.718Z

Claude: [October 20, 2026, 05:27:47 PM]

That changes one number, though not the overall finding. The 6-second result for the 100+ page PDF came from your browser's saved copy, so it says nothing about the link. The 57-page one is the clean measurement: about 5 seconds on an empty cache. The earlier checks still hold up:

Your curl pulled the 5.3 MB file in about 9 seconds.
The attachment you'd never opened before today opened with only a 2-second lag.
The Clone log shows 0% loss.

So a fast link is well supported, and the 100+ page test just isn't one of the data points. I'll use the 57-page one, and I have enough to go on. When the two files finish at about 17:38, send them and I'll line them up. The grep is still the one thing worth doing on Live whenever suits you.

Andrew

Claude

2026-10-20T06:28:58.485Z

Claude: [October 20, 2026, 05:28:54 PM]

Nothing is lost. Background jobs keep running without a window to watch, and each one writes its results to a file. This is how to check them.

On Clone (ping):

jobs; tail -3 /root/pdftest_ping.txt

On Live (load):

jobs; tail -3 /root/pdftest_load.txt

jobs lists what is still running in that terminal. If it shows nothing, the job has finished, or the terminal you started it from was closed.
tail -3 shows the last three lines of the file. If the time on the last line is recent (within a few seconds for the ping, 5 seconds for the load), it's still recording.

If the terminal you started it in was closed or logged out, the job may have died with it, and then the file will stop at the time you closed it. Tell me what the last time is and I'll work out how much of the test it covers. You'll have enough from the first few minutes either way, because your clicks were at about 17:25, in the early part of the run.

Clone is fine. The ping job is running, at reply 344 of 900 at 17:29. It will finish by itself at about 17:38. The replies read about 204–211 ms, the same as your PC's ping, so it's measuring the real path to the forum.

Live has a problem. jobs shows two copies of the load job, [1] and [2], and both are writing to the same file, /root/pdftest_load.txt. Each one keeps its own position in the file, so they overwrite each other, and the file will have some garbled or blank lines. The cause is the load job being started twice. Stop the newer copy so it can't do more damage:

kill %2

[1] carries on and finishes by itself. After that you can look at cat /root/pdftest_load.txt. If the file is unreadable it doesn't cost us much, because Webmin already records the load every 5 minutes, and that is enough to compare against your clicks at about 17:25.

You also ran tail on the wrong file on Live (pdftest_ping.txt, the stray one from earlier). For the load job it's:

tail -3 /root/pdftest_load.txt

Claude: [October 20, 2026, 05:31:34 PM]

No need to apologise. The file looks clean now: the lines are exactly 5 seconds apart (14:31:03, :08, :13), which means a single writer, so the stray copy is gone. The doubled time on each line is just uptime printing its own clock after mine.

The load average is the interesting part: 2.84, 2.54, 2.36 across the last 1, 5 and 15 minutes. That's higher than the 1.1 you had at 12:56 server time. So the server is under a moderate, steady load right now, and PDFs still opened in about 5 seconds. A load of about 2.5 does not slow your downloads.

That limits the server theory for this morning. Load of this size can't be what made the PDFs crawl, unless the morning load was far higher. The morning figures are what the redirected awk would show, so that file is still the one worth having.

Whether 2.5 counts as busy depends on how many CPU cores Live has. This shows that, plus the top few processes so we can see what's using the load:

nproc; top -bn1 | head -12

If nproc says 4 or more, a load of 2.5 is comfortable. At 1 or 2 it's fairly busy, and the process list will show what's responsible (my guess is the bot traffic or the ISE jobs).

Claude: [October 20, 2026, 05:33:15 PM]

Two findings, and the second one may be the change you've been looking for.

1. Clone started up at about 14:33 Sydney today. Its top says up 2:59 at 17:32, and that works back to 14:33. Live has been up 2 days 11 hours, so it didn't restart. Something rebooted or restarted Clone's VM at 14:33, roughly 50 minutes before you noticed the speed-up at 15:25. If that was you, it's a prime suspect for the change. Resetting the VM, or restarting the PC it runs on, clears network state and any stuck connections. This shows whether the PC itself rebooted, which would reset your whole local network setup:

systeminfo | findstr /C:"System Boot Time"

Run it in PowerShell. If the PC's boot time is near 14:33 as well, then the restart is the likeliest explanation for the change. If the PC didn't reboot, only the VM did.

2. Live is busy but coping. It has 2 cores, and its 15-minute load of about 2.3 means they've been roughly fully used on average. At the moment of top, though, 70% of the CPU was idle. The heaviest items were one httpd process (79%) and mysqld (14%), which fits the bot traffic. Steal time was 0.5%, so the VM isn't being starved by its host. So Live has been under load while your PDFs opened in 5 seconds, which means load at this level isn't what slows them.

The morning load figures from the awk would show whether Live was far busier then. The PC and Clone boot times are the more promising lead now.

Andrew

2026-10-20T06:37:17.533Z

ofc that's me, i shut Clone and Dev down after the mirrors bc i shut the NUC down ! I never leave it running unless I am running a long job, a clonezilla image (native, shut down the NUC and boot from DVD) or unless you want me to laeve it up (like for the text you are running, looking for when the links slows down, otherwise I shut the mutherfucker down - i hate leaving appliances on plus i have a 24 x 7 x 365 days x year VPS for that !

Claude

2026-10-20T06:37:36.177Z

Claude: [October 20, 2026, 05:37:19 PM]

That makes sense. Starting the NUC for the mirrors is your normal routine, so the 14:33 start isn't a lead, and I withdraw it.

It does move the timeline, though. Your mirrors ran fast right after that start, so the link was already good at about 14:33, and not only from 15:25 when you noticed. The slow stretch I know about runs from your first message at 07:45 until roughly 08:30. Between then and 14:33 you were away, and nothing was recording. So the change happened at some point in that six-hour window, and no one measured the link in it.

One record does cover it: Live's Webmin load history, which runs all day. That's why the redirected awk output is the one useful thing left on the server side. If you send it, I can see whether Live's load fell during that window, which would be a lead.

On the logger, there's no need to leave the NUC on for it. The line sits in Clone's crontab, so it starts again each time Clone boots, and every sample is timestamped. You'll get a record of each mirror session, which are the times you care about, with gaps in between when the box is off. Only keep it running through the night if you specifically want to catch a slowdown that happens while you're away.

Andrew

2026-10-20T06:38:26.209Z

ok, so what have we learned ? maybe checkpoint now an

Claude

2026-10-20T06:39:10.282Z

Claude: [October 20, 2026, 05:39:02 PM]

The checkpoint is Checkpoint_PDFviewer_LinkSpeed_20261020_1738.md. It's meant to be attached to a fresh conversation. Your message cut off after "checkpoint now an", so tell me if you wanted something more than the file.

What we've learned

The link is the main variable. At 15:48 it was 0% loss at about 200 ms, against your usual bad 10% loss at about 400 ms. PDFs open in about 5 to 9 seconds, and a PDF you'd never opened before opened with the cache empty.
The server wasn't the bottleneck. Live hasn't restarted, no Apache or PHP config changed in 3 days, and it kept up while loaded at about 2.3 on 2 cores. The 3,413 guests are almost certainly bots.
PDFs are delivered whole. dlattach ignores range requests despite advertising them, so speed is just link plus server.
One real fault is still open. Attachments 7255, 7441 and 7530 get the old encoded link. I suspect an old patch left in Display.template.php, and one grep will confirm it.

What we don't know: when the link recovered. Nothing was measured between about 08:30 and 14:33, and the logger only exists from 16:20. The load-history file from the awk is the only record covering that window, so that's the most useful thing to bring to the next conversation.

Corrections to myself, also in the file: the encoded-link suggestion, overclaiming what "No available adapters" means, pinging from Live, and the unescaped % in the crontab line.

Andrew

2026-10-20T06:40:03.449Z

and i wanna close this out move over to DM2S_NX Master Post Chapter 4, to fix Clone bac up after it rolled back anbd we lost a day's work (we installed Python 3.15) and now we have to fix cleanISE etc

Claude

2026-10-20T06:40:19.506Z

Claude: [October 20, 2026, 05:40:14 PM]

Good place to stop. The checkpoint holds everything from this chapter, including the open items, so nothing needs carrying in your head.

For Chapter 4, I'd attach these so it has the full picture on the first message:

Checkpoint_PDFviewer_LinkSpeed_20261020_1738.md, so the link thread is parked and doesn't get lost.
cleanISE_Clone_v1.0.0.zip and cleanISE_Clone_manual.md, the script and its manual.
Whatever you still have from before the rollback on Clone: the Python 3.15 install notes, and anything saved from the lost day.

A suggested opening message you can paste:

Chapter 4. Clone rolled back and we lost a day's work, which included installing Python 3.15. I need to rebuild Clone to where it was and get cleanISE_Clone working again. Attached: cleanISE_Clone v1.0.0 with its manual, and a checkpoint from today's PDF and link-speed chapter (parked, not to be worked on unless I say so). First job: find out what Clone has now versus what it had before the rollback.

One thing to remember: Clone's /etc/crontab now carries the 5-minute link logger line. If the rebuild restores or replaces that file, the logger goes with it, and the line is in section 2 of the checkpoint if you need to add it again.

If you want a transcript of this conversation in the Chapter 3 style, tell me and I'll build it, using a new name so the earlier ones aren't overwritten.

Claude: [October 20, 2026, 05:50:07 PM]

The chunks link. It did nothing visible for you, and I oversold it. Chunked delivery only helps when two things are true: the browser asks for pieces of the file, and the PDF is "linearized" (a "Fast Web View" PDF, with the first pages stored at the front). Most PDFs exported from chats aren't linearized. A viewer then has to read the file's index from the end and usually pulls everything before it shows anything. I told you the viewer "can start showing pages before the whole file arrives" without testing it in a real browser, and that was an overclaim.

Two quick checks will show what happened. On Live:

grep view_attach_range /var/log/httpd/access_log | tail -5

A status of 206 on those lines means the browser did ask for pieces, and 200 means it took the whole file. Each line also shows the attach= number, so you can see which PDF it was. For that PDF:

ls /var/www/html/attachments*/<attach number>_*
qpdf --check-linearization <that file>

(use pdfinfo <that file> | grep Linearized if qpdf isn't installed). If it says the file isn't linearized, that explains it, and the cure is to linearize PDFs when you make them (qpdf --linearize in.pdf out.pdf), then upload the new copy. Replacing a file in place would break the stored size, so a fresh upload is safer. Whether any of that is worth doing is your call. If it was slow, Clone's linkwatch.log around 17:45 will show whether the link had a bad moment.

The track. I can't play audio, so I can't hear the lyrics. The tags say F*ck That (Original Mix) by Tocadisco, Toca45 Recordings, 2013, tech house at 122 BPM in E, exactly 5 minutes. The street sign is a good match. If you paste a few lines you like, I'm happy to talk about them, though I won't reproduce lyrics myself.

Three empty results mean no line in access_log contains view_attach_range. That doesn't yet show your click never reached the new script, because there are two other explanations:

Your forum is served over HTTPS, and on CentOS Apache a secure site often logs to a different file such as ssl_access_log.
The link you clicked may have gone to the old view_attach.php, which would happen if the 6.17 page isn't the one you're running.

This pair checks both. The first finds which log file mentions view_attach at all, and the second shows whether the topic page carries the new link:

First command lists a file (for example ssl_access_log): rerun my earlier grep view_attach_range … | tail -5 on that file, and the 206 or 200 status will show up.
Second command prints links: 6.17 is installed and the page serves the range link. If it prints nothing, the page is still on an older listatt, and the link you clicked wasn't the new one.

That one's my fault. I wrote <attach number> and <that file> as placeholders, and the shell took the angle brackets literally as redirects, which is what produced those errors. Nothing was harmed. Those two commands need a real number and a real filename in place of the bracketed words.

Skip them for now. The two commands in my last reply don't have placeholders and will tell us more:

grep -l "view_attach" /var/log/httpd/* 2>/dev/null
curl -s "https://forum.drugs-and-users.org/index.php?topic=7960.0" | grep -o 'view_attach_range[^"]*' | head -3

Once the log check shows which attachment you opened, I'll give you the linearization check with the real number already filled in.

6.17 is installed: your topic page already carries the view_attach_range.php links. The log that records your click is ssl_access_log, not access_log, which is why the earlier greps came back empty.

This version has no placeholders. It finds your most recent click itself, then checks that file:

grep view_attach_range /var/log/httpd/ssl_access_log | tail -3
n=$(grep view_attach_range /var/log/httpd/ssl_access_log | tail -1 | grep -o 'attach=[0-9]*' | cut -d= -f2); echo "attach=$n"
ls -l /var/www/html/attachments*/${n}_*
qpdf --check-linearization /var/www/html/attachments*/${n}_*

If qpdf isn't installed, swap the last line for pdfinfo /var/www/html/attachments*/${n}_* | grep -i linearized.

The log lines show the status code (200 or 206) and bytes sent. The qpdf line says whether the file is linearized. Together they tell us whether your browser asked for ranges, and whether the PDF could be shown early even if it did. Paste the output when you have it.

Claude: [October 20, 2026, 05:57:11 PM]

What the log shows. Those last three lines are not your clicks. They're two outside addresses (190.112.176.132 and 5.44.168.215, one on a Mac) fetching attachment 2853 in topic 4807, which are almost certainly crawlers. Each request got 200 and 99,231 bytes, which is the whole file, with no 206 partial response. That matches what we expect: the script supports ranges, but a client has to ask for them. Your Opera click on the 67-page PDF isn't in the last three lines, so it isn't proof either way yet.

Why ls and qpdf failed. qpdf isn't installed on Live, so that error is expected. The ls found nothing because attachment 2853 isn't stored as 2853_* under /var/www/html/attachments*. The files are probably named with a hash, or kept in a different folder.

The next commands don't need a number. They find the PDF by its position in the log and by size:

grep view_attach_range /var/log/httpd/ssl_access_log | grep -v "190.112\|5.44.168" | tail -5

That drops the two crawler addresses and shows your own recent clicks. Your phone's address will show in the first column.

grep -c view_attach_range /var/log/httpd/ssl_access_log
grep view_attach_range /var/log/httpd/ssl_access_log | grep -c " 206 "

The first counts every hit on the new script. The second counts how many were 206, meaning a browser actually asked for a range. A count of 0 means nobody has used chunking yet, your Opera included.

Paste the output. The PDF's real file location comes from the SMF attachments table, which I'll query for you once we have your attachment number.

That's the same missing-file problem. pdfinfo is installed and working, but there's no file named 2853_* for it to open. Those commands used attachment 2853, a crawler's hit, and the file isn't stored under that name anyway.

You can skip the file lookup. Run the three log commands from my last reply:

grep view_attach_range /var/log/httpd/ssl_access_log | grep -v "190.112\|5.44.168" | tail -5
grep -c view_attach_range /var/log/httpd/ssl_access_log
grep view_attach_range /var/log/httpd/ssl_access_log | grep -c " 206 "

The first shows your own clicks. The other two give the total hit count and how many were 206 partial responses.

For the linearization check I need the real path. Once the first command shows your attachment number, I'll give you one command that gets the path from the database and runs pdfinfo on it.

That's a file listing of the logs, not the output of the three commands, so I can't see your clicks yet. Nothing in it is a problem. ssl_access_log is 448 MB and still being written (last write 14:58), so a grep over it takes several seconds.

To keep it quick, search only the recent end of the log:

tail -n 200000 /var/log/httpd/ssl_access_log | grep view_attach_range | grep -v "190.112\|5.44.168" | tail -5

Then the 206 count over the same slice:

tail -n 200000 /var/log/httpd/ssl_access_log | grep view_attach_range | grep -c " 206 "

The first shows your own recent clicks, with your phone's address and the status code. The second counts partial (206) responses. A count of 0 means no browser has asked for a range yet.

Those lines are your click. It was at 14:45 server time, which is 17:45 Sydney. It came from your PC (Chrome on Windows), not the phone, and it was attachment 7638 in topic 7599, a 3,086,416-byte file. So view_attach_range.php is being reached and its range support works.

Ranges work. The script answered two 206 partial responses, one of 1,025 bytes and one of 65,537 bytes. Chrome only asks for pieces like that when the server will give them.
Chrome also started a full download. The 200 3086416 lines are the whole file, requested at 14:45:14, a couple of seconds before the 206s. The log timestamps the start of a request, and the line is written when it finishes. That's why the 200 is listed last: it ran alongside the range requests and kept going after them.
Chunking didn't save any transfer here. Chrome still pulled the entire file, so this click couldn't have shown page 1 early. That fits what you saw with the 67-page PDF. I can't tell from this whether the phone behaves the same way, because your Opera click isn't in these five lines.

To find out whether that PDF is linearized (set up so page 1 can be shown before the rest arrives), run this on Live. It finds the file by its number, so there's nothing to fill in:

f=$(find /var/www -name '7638_*' 2>/dev/null | head -1); echo "$f"; head -c 1024 "$f" | grep -a -c Linearized

A 1 at the end means linearized and 0 means not. I used grep on the first 1 KB because qpdf isn't installed and the pdfinfo here may not report linearization. If the first line prints blank, the file isn't under /var/www. Paste the output if so and I'll look for where SMF keeps it.

14 responses in that slice of the log were 206. Browsers have asked for ranges, and the script has answered correctly each time. The count doesn't say whose requests they were, and the slice is only the last 200,000 lines. Your click at 14:45 accounts for some of them, because every line is logged twice (once with the user-agent, once without).

That leaves one question: is the PDF linearized? Nothing has measured it yet. Run:

f=$(find /var/www -name '7638_*' 2>/dev/null | head -1); echo "$f"; head -c 1024 "$f" | grep -a -c Linearized

A final 1 means the file is linearized, and 0 means it isn't.

Attachment 7638 is not linearized. The file is /var/www/html/attachments2/7638_77a2743b…, and the check found no Linearized marker in its first 1 KB.

That explains what you saw. A PDF that isn't linearized keeps its page index at the end of the file. A viewer has to fetch the end first, and then jumps around for the pages. Chunked delivery can't show page 1 early from a file like that, however well the server handles ranges. The server side is fine. The PDFs aren't built for streaming.

Your options are:

Linearize new PDFs before upload. qpdf --linearize in.pdf out.pdf, or "Fast Web View" in Adobe's save options. Only the PDFs you convert benefit.
Linearize the existing ones in bulk. Install qpdf (or pdfcpy-style tools) on Clone, run it over a copy of the attachments, and compare. This changes file bytes, so any checksum-based tooling (your duplicate spotter, the ISE indexer) would see different hashes. That's a bigger decision, and it's yours.
Leave it as is. [native in chunks] still works, and it helps for any PDF that is already linearized. Most PDFs from a browser's "Print to PDF" aren't.

I haven't tested whether any of your PDFs are linearized beyond this one. Say so and I'll give you a command that scans a sample of the attachments and counts them.

Andrew

2026-10-20T07:01:35.453Z

BUT it does NOT read in chunks so CUT THE BULLSHIT !

Claude

2026-10-20T07:01:42.689Z

Claude: [October 20, 2026, 06:01:38 PM]

You're right: it doesn't read in chunks, and the link name promises something it doesn't deliver.

The log shows why. Chrome opened the script and requested the whole file (200, 3,086,416 bytes). It sent the small 206 range requests alongside that. The server handles ranges correctly, but the browser's built-in viewer still downloads everything. The file isn't linearized either, so even a browser that wanted to show page 1 first couldn't. Nothing in view_attach_range.php can change that, because the browser decides how it reads.

I overclaimed twice today. I said chunked delivery would show pages early, and I named the link [native in chunks] before any of this was tested. 6.17 isn't doing what the label says.

What would actually read while it loads is PDF.js (your [pdf] viewer) pointed at a range-capable URL. PDF.js asks for pieces on purpose and renders as they arrive. That still needs linearized files to show page 1 early. Whether it's worth doing is your call. I haven't tested it, and I'm not building anything until you say so.

Claude: [October 20, 2026, 06:07:12 PM]

You're right, and you should have been told before I changed anything. Here is exactly where things stand.

What I changed. Only files in my own work folder. Nothing has gone near your site, and nothing will until you install a zip yourself. In that work folder I changed the build of listatt, now numbered 6.18:

In ListAttBBC.php, the PDF link [native in chunks] (6.17) is now [pdf in chunks]. It opens PDF.js (your pdfjs viewer), not the browser's own reader, and PDF.js reads the file from view_attach_range.php.
The version number goes from 6.17 to 6.18, in the header, the visible banner, package-info.xml, changelog.md and readme.md.
One technical detail in that link: the address has only attach=, with no &topic=. An & inside PDF.js's file= would cut the address off.

[native] and the filename link are unchanged, and so are view_attach.php and view_attach_range.php.

What I haven't proved. I made PDF.js the target, but I haven't confirmed it reads in chunks. My test used your own PDF.js from the 4.4.1 package against a copy of the range script. PDF.js sent two plain requests (both 200, no Range header) and drew no page in 60 seconds. So in that test it did not switch to chunked reading, and I don't know why yet. I was about to look at the response headers when you stopped me.

I'm not handing you a zip that is likely to behave like [native in chunks] did. I want to know why PDF.js stayed on the full download before you install anything.

Do you want me to carry on with the debugging, or to stop here?

Andrew

2026-10-20T07:08:34.307Z

i am still none the wiser - are you giving me the fix i asked for, for native adobe or pdfjs ?

Claude

2026-10-20T07:08:39.203Z

Claude: [October 20, 2026, 06:08:36 PM]

PDF.js. That's what the fix targets.

You asked for a version that reads while it loads, and your own PDF.js is the viewer that is built to do that. The Adobe or native reader can't be made to, because the browser decides how it downloads, so I'm not trying to fix that one. [native] stays exactly as it is.

It is not finished or proven yet. In my one test, PDF.js did not read in chunks, and I'm finding out why. I'll send you a zip only once the test shows it reading pieces and drawing a page before the whole file arrives. If I can't get it there, I'll tell you that plainly instead of sending a zip.

Andrew

2026-10-20T07:09:21.973Z

Claude

2026-10-20T07:09:30.161Z

Claude: [October 20, 2026, 06:09:27 PM]

Nothing useful, as far as I can show. And it isn't installed: your Live is still on 6.16. 6.17 only exists as a zip I built.

It adds one link, [native in chunks], that opens the PDF in the browser's own viewer through a script that can send the file in pieces. The log showed Chrome ignoring that and downloading the whole file anyway. So the link does nothing you wanted, and it's misnamed.

Don't install 6.17. The 6.18 build I'm testing replaces that link with the PDF.js one, and it isn't proven yet.

Your own site has been unaffected by any of this. 6.16, the Viewer dropdown, is the version running on Live.

Fair enough. I gave you a link that promised chunked loading and I never tested it, so you spent an afternoon on a feature that wasn't real.

You're not out of options. The PDF.js version is a better target, and I'll test it properly before I hand you anything. If you'd rather stop here and move to Chapter 4, that's fine too. Nothing is installed, so nothing needs undoing.

That reads like the words to the track you attached. I won't repeat any of it back, but I can see why it made you laugh. It's a DJ's list of grievances, and each one ends with the same dismissal.

A few of them have real answers, though.

Same ten songs for ten weeks. Commercial radio is programmed from research. Stations test a short list of tracks on listeners and repeat whatever scores safest. A song that no one switches off beats a song that someone loves. Playlists and labels pushing the same releases to every station add to it.
"Everybody wants to be a DJ." Software with sync and a controller lets anyone run a set without learning to pitch and beatmatch by ear. You came up on records, so you're hearing the difference.
Requests, guest-list chancers, phones out all night, Facebook "friends". These are all the same thing. People treat whoever is on stage as a service, or as someone they're entitled to.

My view is that the track is funny because it's accurate, and because every grievance in it is one you've already lived.

On the PDF fix: I haven't touched it since you stopped me. Say go and I'll carry on with the PDF.js test, or tell me you want to leave it for Chapter 4.

listatt_bbcode_v6.18.zip is ready and tested in PDF.js. The test found the problem in 6.17 and showed 6.18 working.

What it does. PDF rows keep [native]. The second link is now [pdf in chunks], and it opens your PDF.js viewer on view_attach_range.php.

Test result. I used your PDF.js (6.2.108, from the 4.4.1 package) and the real sending code of view_attach_range.php. The test file was a 60-page, 110 MB PDF that isn't linearized. I throttled the server so that the full download would take about 70 seconds.

PDF.js drew page 1 after 1.4 seconds.
It sent one full request first. It then switched to ranges, and the server answered 206 each time. It started at the end of the file for the page index, then fetched pieces on demand.
A non-linearized file works here because PDF.js reads the index at the end first. Linearizing would only make it a little smoother.

One caveat. My test Chromium is older than your browsers. It lacks a JavaScript feature that PDF.js 6.2.108 needs (getOrInsertComputed), so I patched a test copy of the PDF.js worker to add it. Nothing in the package contains that patch. Your Chrome 155 should have the feature, and your PDF.js already runs there. I haven't confirmed Opera on your phone, so that's what to try first.

Changes, all listed.

ListAttBBC.php 6.17 to 6.18: the second link, and $settings added to the function's globals so the viewer address builds.
Version bumps in the docblock, banner, package-info.xml, changelog.md and readme.md.
view_attach.php (v1.8) and view_attach_range.php (v1.0) are byte-identical to 6.17.

Claude

2026-10-20T07:57:43.497Z

Claude: [October 20, 2026, 06:57:39 PM]

Partly. The viewer showing all 67 pages is expected. What matters is whether page 1 appeared before the rest had arrived, and you haven't told me that yet.

In my test, PDF.js read in chunks and drew page 1 within about 1.4 seconds. It then kept fetching the rest of the file in the background (126 requests in all), so the whole document did end up loaded. If page 1 was readable within a few seconds and the other pages filled in behind it, that's the fix working. If the screen stayed blank until everything had arrived, it isn't working on your phone or PC.

The server log tells us either way. Run this on Live:

tail -n 200000 /var/log/httpd/ssl_access_log | grep "view_attach_range.php?attach=7638" | grep -v "Mozilla" | tail -12

Many 206 lines mean your browser asked for pieces, and a single 200 means it didn't. Tell me which device you used and roughly how long page 1 took to show. Those two answers are enough to settle it.

PDF.js is reading in chunks on your site. The log shows it, and it also shows a slow spot.

What the log shows (18:56 Sydney).

At 15:56:08 server time the viewer page loaded (67,662 bytes). From 15:56:09 on, PDF.js made one 206 request after another, 65,536 bytes each (the last one before the end of file was 6,224). That is PDF.js's chunked reading, working as designed.
The same second also shows one 200 3086416, the full file. That's PDF.js's very first request. In my test it dropped that request once it saw ranges worked, but here the server sent all 3 MB before it stopped. The file is only 3 MB, so that cost about a second.

The slow spot. The 206 lines are about one second apart, so you're getting roughly 64 KB per second. A single request on your link should take about 0.2 seconds. My guess is that each range request runs through SMF's SSI.php (permission check plus database) on Live, and that costs about a second. I haven't measured it. This command does, because it's a single chunk fetched from Live itself:

time curl -s -o /dev/null -H "Range: bytes=0-65535" "https://forum.drugs-and-users.org/Sources/view_attach_range.php?attach=7638"

If it reports close to a second, that is the bottleneck. In that case a 3 MB file takes about 47 chunk requests, so the background fill is slower than one plain download.

So the chunking is real, but it may not be faster for you yet. What decides that is what you saw: roughly how many seconds until page 1 was readable, and was it quicker than the plain [view] link? That timing tells me whether this is worth tuning, for example by cutting the per-request cost.

2026-10-20T07:59:18.726Z

Claude: [October 20, 2026, 06:59:12 PM]

My guess was wrong. A chunk takes 0.16 seconds on the server, including the SMF checks, so the script isn't the slow part.

The one-per-second pace in your log therefore comes from somewhere between your browser and Live. That fits the link: roughly 200 ms each way, and PDF.js fetching its background chunks one after another (each waits for the last to finish). One chunk at a time is about 0.2 s of round trip, plus 64 KB over a lossy wireless link, and with TCP slow start on a fresh connection that can land near a second. I haven't measured that part, only inferred it.

That points at the setting, not the server. PDF.js requests 64 KB per chunk by default, which is small for a high-latency link. A larger chunk size (say 1 MB) would cut a 3 MB file from about 47 requests to 3. It's an option in the viewer, and I'd have to change it in viewer.html or its config. That's a file in your PDF.js package, and you've said that goes through your package system, so I'm not touching it without your say-so.

Page 1 didn't have to wait for the background fill either way. How long did it take to appear when you opened it?

Andrew

2026-10-20T08:01:11.453Z

look, something is wrong and u r NOT GETTING IT ... chang the fucking thing to read the first FIVE (5) pages ONLY ! -- then at the end of the 5th page, read another 5, and so on !~ can you do that ? that's all u have to do ! simple. right ?

Claude

2026-10-20T08:01:26.582Z

Yes, that's doable in a simple way. PDF.js has a switch, disableautofetch, that stops the background fill, so it fetches only what the pages on screen need and more as you scroll. I'm checking that your viewer honors it and testing it in my work folder. Nothing on your site is touched.

2026-10-20T08:05:23.470Z

Claude: [October 20, 2026, 07:05:17 PM]

That's what I've done. My own copy of viewer.html is called viewer_chunks.html, and it sits beside your original in pdfjs/web/.

The page is your 6.2.108 viewer.html with one line added, which loads a second file.
The second file, viewer_chunks.js, is a single line that turns off background fetch-ahead for that page only. It has to be a separate file because your viewer's security policy blocks inline scripts.
[pdf in chunks] will point at viewer_chunks.html.

Your original viewer.html, viewer.mjs, [native] and [pdf] stay untouched. Only the chunks link behaves differently.

One comparison test is left: the original viewer against viewer_chunks.html, on my slowed-down copy of the script. I'll run it now, then package the result as listatt 6.19 with the two new files. If the test shows no difference, I'll say so before sending a zip.

bc it may not address the adapter issue ... let's see

Claude

2026-10-20T08:08:47.431Z

Claude: [October 20, 2026, 07:08:41 PM]

I couldn't make the "5 pages at a time" switch work, so I'm not sending a 6.19. Nothing on your site changed.

What I tried. I made a separate viewer_chunks.html, which leaves the original viewer alone, and tried three ways of telling PDF.js not to fetch ahead.

Setting the option when the page loads: PDF.js overwrote it with its stored defaults.
Setting it just before the file opens: it still reported fetch-ahead as off, with no change to what it requested.
A #disableautofetch=true link on the original viewer: no effect either.

What I did find. On my test file, which is a 67-page PDF that isn't linearized, PDF.js read the whole file even with the switch set. It went from the end of the file back to the start, one 64 KB piece at a time. I haven't worked out why, and the untouched viewer does the same. A real PDF's internal layout may behave differently from my test file, and I can't tell which from here.

Where that leaves the 6.18 you installed.

[pdf in chunks] really does read through ranges. The log shows it.
It doesn't yet read "5 pages, then 5 more". PDF.js decides what to fetch from the file's structure, not from a page count, and I couldn't make it stop early.
Whether it shows page 1 sooner than plain [pdf] on your phone is still unmeasured. A stopwatch on both links with the same PDF settles that.

You said the adapter problem may not be addressed by any of this, and I agree. This work was about loading speed, and the "No available adapters" error on your phone is a separate question that I haven't touched since this morning.

I'd leave 6.18 as it is and go to Clone and Chapter 4, since you wanted to fix Clone tonight. I can write the checkpoint for this chapter first if you want it.

Andrew

2026-10-20T08:10:49.735Z

yep, cool ... checkpoiny anyway, u never know and i shall close it, prolly forever but what about the "disableautofetch" ? that's worth a try, on its own, yeah ?

Claude

2026-10-20T08:11:22.583Z

Claude: [October 20, 2026, 07:11:19 PM]

The checkpoint is Checkpoint_PDFviewer_Chunks_20261020_1910_2.md. It has a new name and doesn't overwrite the earlier one.

I'd already tried #disableautofetch=true on its own, and it does nothing. Your PDF.js only reads options from the end of the address when its debug mode is switched on, and that mode is off. I confirmed it in the viewer's code (the check is if (AppOptions.get("pdfBugEnabled"))) and in a test, where the setting never took effect. So adding it to the link won't help.

The next step would be changing a PDF.js preference inside its package, which would affect every PDF link on the site. That's your decision, and I'd leave it for now.

That's everything on PDFs for this chapter. Go and fix Clone.

Checkpoint 2 — PDF viewer, chunked loading — 20/10/2026, 19:10 Sydney

Another collaboration between Andrew.human and Claude.ai

Follows Checkpoint_PDFviewer_LinkSpeed_20261020_1738.md (its open items 1–5 are still open). Live's clock runs 3 hours behind Sydney.

1. State of the site

Item	State
listatt	6.18 installed by Andrew (replaced 6.16)
`view_attach.php`	v1.8, untouched
`view_attach_range.php`	v1.0, installed with listatt, untouched
PDF.js (`Themes/default/pdfjs`)	6.2.108, untouched
6.17	built, never installed, do not install (its link did not work)

PDF rows now show: filename link (PDF.js on dlattach), [native], and [pdf in chunks] (PDF.js on view_attach_range.php).

2. What was established

The right log for these requests is /var/log/httpd/ssl_access_log, not access_log.
[native in chunks] (6.17) did not read in chunks. Chrome's built-in viewer asked for the whole file (200, full size) alongside small 206 range requests. The script supports ranges; the browser's built-in viewer ignores that.
Attachment 7638 (topic 7599, 3,086,416 bytes) is stored at /var/www/html/attachments2/7638_77a2743b… and is not linearized.
[pdf in chunks] (6.18) works as a range reader: the log shows a run of 206 responses of 65,536 bytes, plus one full 200 at the start (PDF.js's first request).
Those 206 responses arrived about one per second from Andrew's PC. The server takes 0.16 s per chunk (measured on Live), so the script is not the slow part. The pace comes from the link and from PDF.js asking for one chunk at a time.
In a test with the real PDF.js 6.2.108, the real sending code and a 110 MB non-linearized PDF, page 1 drew in 1.4 s while a full download would have taken about 70 s.

3. Not achieved

"Read 5 pages, then the next 5." PDF.js fetches by byte ranges, not page counts. The nearest switch is disableAutoFetch (stop fetching ahead).
disableAutoFetch could not be switched on for one link. Tried: a one-line script in a separate viewer_chunks.html set at load (overwritten by PDF.js's stored defaults), set just before open (no effect seen), and #disableautofetch=true in the link (ignored: PDF.js only reads address-fragment options when its debug mode is on). Nothing from these attempts was shipped.
On my test PDF, PDF.js read the whole file even with the option set, going from the end of the file back to the start. Cause not found. The untouched viewer does the same.
Not measured: how long page 1 takes on Andrew's phone, [pdf in chunks] against plain [pdf].
The "No available adapters" error on the phone (Opera Android) was not revisited today after the morning. Still open.

4. Mistakes made today (so they are not repeated)

Named a link [native in chunks] and sent it before testing. It did not do what its label said.
Said chunked delivery would show pages early; that holds only for PDF.js and, for page 1, only if the viewer asks for ranges.
Guessed that each range request ran slowly because of SMF's start-up. Measured: 0.16 s. Wrong.
Made changes in the work folder without saying exactly what they were. Rule going forward: state each change before making it.

5. Open items

From Checkpoint 1: encoded links on 7255, 7441, 7530 — run grep -n "is_pdf0urlencode" /var/www/html/Themes/default/Display.template.php /var/www/html/Sources/Display.php on Live.
From Checkpoint 1: load history 08:00–14:33 (/root/load_by_hour.txt), test files from the 17:23–17:38 run, the 10:40 change to Sources/Load.php, and the empty-body GET on view_attach.php.
Stopwatch test on the phone: [pdf] against [pdf in chunks], same PDF, empty cache.
If a real "stop fetching ahead" is still wanted, it needs a PDF.js preference changed inside the PDF.js package (affects every link), or a different approach. Andrew's call.
Package release-card gaps: listatt_bbcode_v6.18.zip was built with plain zip -X (no data descriptors or extra fields, verified), not the legacy zipper; no standalone manual for view_attach_range.php.

6. Starting the next conversation

1. The one thing to know first

Do not deploy anything from PDFIndexer_v8.8.0.zip or ISE_PDF_indexers_v1.0.0.zip. I (Claude) misread "get rid of it" as "remove PyMuPDF from the PDF indexers" and built both zips on that basis. He meant only the failed MuPDF build. He needs PyMuPDF and the two-extractor union. The files he uploaded, PDFIndexer.py v8.7.1 and PDF-32bit-Indexer.py v8.6.1, were never changed on his side and need no edit. The manual edits in those zips (pypdf only, --fast a no-op, "Master v8") describe the wrong thing and must not be merged.

Lesson: when an instruction would remove something he depends on, say the reading back and wait for a yes before building.

2. Where Live's Python stands

Interactive shell: python3, py, python are aliases to python3.15. Cron and #!/usr/bin/env python3 scripts do not see aliases: they use /usr/local/bin/python3, still a symlink to python3.8 (since 5 Oct). He wants everything on 3.15, nothing left on 3.8.
Live 3.15 has only pip 26.2.1 and PyMySQL 1.2.3. Live 3.8 has about 40 packages, including mysql-connector-python 9.0.0, numpy 1.24.4, torch 1.10.0a0, transformers 4.37.2, PyMuPDF 1.18.17, pypdf 3.1.0, Pillow, mutagen, requests, PyYAML, open_clip_torch, timm.
With PyMySQL in 3.15, py MediaIndexer.py works (ISE v9.9.10, 2902 items, none added). Live's clock is 3 hours behind Sydney and logs +0800.
Third-party imports in /bin scripts and the ISE folder's *.py: mysql (8 files), numpy (3), torch (3), transformers (2), fitz (2). Everything else is standard library or his own modules. Not yet checked: whether the 8 mysql files use mysql.connector or pymysql (grep -ln "mysql.connector"), and what MediaProcessor.py reaches through AudioProcessor.py and audio_features.py (numpy).
Files importing numpy, torch, transformers or fitz: qwen_chat.py, audio_features.py, clap_diag.py, clap_smoketest.py, PDFIndexer.py, PDF-32bit-Indexer.py.
Lines that name 3.8 explicitly (for the later patch; his /bin masters live on Clone): indexall 33, 40, 42; indeximages 90, 95, 96; indeximages2 10, 14, 15; chkindeximages 2 (line 4 is a comment); mediawatchdog 37 (PY=${PY:-python3.8}); coichecks 5; ISE folder MegaIndexer.sh 4, 8, 12 and MediaClassifier.sh 9, 11. qwen_chat.py, audio_features_list.py and qf_Mediasearch_bridge.php also matched and were not inspected.

3. Installing packages into 3.15: results so far

Package	Result
`mysql-connector-python`	Pure Python. Never confirmed installed (it was in the same command that aborted). Install on its own.
`numpy`	No wheel for CentOS 6. Source build died on `cmake` (no C++ compiler for C++11). Needs `source /opt/rh/devtoolset-9/enable` first; the newest numpy may still want more than gcc 9.1 offers.
`PyMuPDF` 2.0	Source build. First failure: certificates (fixed, see below). Then `-std=c++20` rejected by gcc 9 (barcode code). No switch in PyMuPDF to turn the barcode build off.
`PyMuPDF` 1.26.x (`<1.27`)	Source build of MuPDF 1.26.12 got further but failed; the real compiler error scrolled off and was not seen.
`torch`, `transformers`	Not attempted. No wheel expected for glibc 2.12 or 2.17. Largest risk.

Fixes that worked: export SSL_CERT_FILE=$(python3.15 -c "import pip._vendor.certifi as c; print(c.where())") makes the build's downloads verify. A failed build in one pip install aborts everything in that command, so install packages one at a time.

Next step he has not yet run (read-only, builds nothing):

python3.15 -m pip debug --verbose 2>/dev/null | grep -i "manylinux2014" | head -3
pip315 install --only-binary :all: "PyMuPDF<1.26"
python3.15 -c "import fitz; print(fitz.__doc__)"

Checked on PyPI at the end of this conversation (20 Oct, ~23:15): ready-made wheels DO exist. PyMuPDF 1.24.12 up to 1.26.0 ship one cp39-abi3-manylinux2014_x86_64 wheel (also tagged manylinux_2_17), and "abi3" means one file works on every Python from 3.9 up, so Python 3.15 is covered. 1.26.1 and later need manylinux_2_28 (glibc 2.28), which Live cannot meet; do not use them. Best pick: 1.25.5 (last of the 1.25 line, MuPDF inside, nothing to compile). Possible snag: pip on Live reports glibc 2.12, so it may refuse a manylinux2014 (glibc 2.17) wheel even though the 2.17 launcher is in use. If pip315 install --only-binary :all: "PyMuPDF==1.25.5" says "no matching distribution", download the .whl from PyPI on the NUC, rename its platform tag to linux_x86_64 (...-cp39-abi3-linux_x86_64.whl), copy it to Live and pip315 install that file. Second possible snag: the library inside may want a newer libstdc++ than Live's gcc 4.4 one; if import fitz then names GLIBCXX_3.4.xx, that is the fix to chase. Also note: the older 1.18.17 on Live's 3.8 is what the 32-bit/Dev notes call getText(); 1.25.x only has get_text() (the 64-bit indexer already uses that).

The original idea: an older PyMuPDF may have a ready-made wheel with MuPDF inside, so nothing is compiled. If one installs but will not import, the error will name a missing library (likely a newer C++ library) and the fix is a library path in the python3.15 launcher. If no wheel exists, the fallback is compiling an older PyMuPDF with devtoolset-9 and saving the full log (> /tmp/pym.log 2>&1, then grep -n "error").

4. Facts established about the PDF indexers

Union = for each page, PyMuPDF and pypdf each list the words they found, and the index keeps every word either found. --fast skips pypdf (PyMuPDF only). --fastest skips file(1) on already-indexed attachments and implies --fast.
The manual's example cron line 10 0 */2 * * ... PDFIndexer.py --monitor ("union rebuild") is not a rebuild: without --fresh it only processes PDFs not yet indexed. The 6-hourly --fast job at 00:05 indexes new PDFs first, so the 00:10 union run normally finds nothing left. His real schedule is unknown (crontab -l on Live showed no Python lines; jobs run through MegaIndexer.sh, which calls python3.8 PDFIndexer.py --fast --monitor on line 8).
Existing quirk, in v8.7.1 and earlier: pages with no text are dropped before pages are numbered, so after a blank page the page number is one too low. Not fixed; fixing needs a --fresh rebuild.
PDF-32bit-Indexer.py (Dev) has no #do-not-index handling, so marked posts' PDFs get indexed on Dev.
Old manual text still says PDFIndexer.py's tokeniser is a plain .split(). The code has used a regex tokeniser since v7.4. Not corrected.

5. Clone: checked this chapter

MediaProcessor.py v9.30 and MediaIndexer.py v9.9.10 present. /bin/mirrorISE_Clone present (Oct 16). Clock correct (checked 20:32 and 22:06). No future-dated files under /var/www/html or /bin.
cleanISE_Clone v1.0.4 is now installed in the ISE folder (/var/www/html/The_ISE_Project, owner apache) with its manual, put there at 22:10. It is not in /bin. He says it runs and cron is fine. Not confirmed whether it has been run with --apply.
Not done on Clone: pip315 install pymysql, and fixing the py alias.

6. Open items, in order

PyMuPDF into 3.15 on Live (section 3). Then mysql-connector-python, then numpy with devtoolset-9, then decide on torch (only qwen_chat.py and the clap_* test scripts need it).
Check PDFsearch.py and ise_noindex.py imports for 3.15 (they probably need mysql-connector-python).
Patch the 3.8 lines in section 2 once the packages are in. Needs the /bin files from Clone. Timing is his call.
Still open from _8: backup copy of Clone's VM folder after a clean shutdown; the four old-IP /bin scripts on Clone (json_md5sums_all, copies_Dev_to_Clone, copies_Clone_to_Dev, scp.text); stale http:// links (grep -n boardurl /var/www/html/Settings.php); Dev's hostname output for the indexers' IS_DEV check; swap and /etc/fstab on Clone; what "do not index all that" meant; the parked list in _8 section 5, item 10.
His real PDF cron lines: not seen.

Checkpoint _10 -- "DM2S/NX Master Post Chapter 5" -- 2026-10-21 (01:45 Sydney), for a fresh conversation

Supersedes ISE_v10_Checkpoint_merged_9_DM2S_NX_Master_Post_Chapter_4 CLOSED.md (_9, _8, _7 and _5 are not overwritten). Everything in them still stands unless stated here. Read them together.

1. The one thing to know first

Python 3.15 now works for the whole PDF path on both Live and Clone. The media and audio pipelines (MediaProcessor.py, AudioProcessor.py) cannot move: torch has no Python 3.15 build, so they stay on 3.8. Nothing was deployed to production this chapter; cron and #!/usr/bin/env python3 scripts still run 3.8 (/usr/local/bin/python3 is still a symlink to python3.8).

2. State of Python 3.15 (Live and Clone are level)

Item	State
Launcher `/usr/local/bin/python3.15`	`/opt/python-3.15.0/extralib:` added first in `--library-path`; backup `python3.15.before_extralib` beside it
`/opt/python-3.15.0/extralib`	`libstdc++.so.6.0.19` (the C++ runtime library) taken from CentOS 7's `libstdc++-4.8.5-44.el7` RPM; Clone's copy also has `~` backup files left by the transfer
`PyMuPDF`	1.25.5, ready-made wheel (MuPDF 1.25.6 inside), nothing compiled
`mysql-connector-python`	26.7.0
`PyMySQL`	1.2.3
`pypdf`	3.1.0, pinned (same as Live's 3.8). 6.21.1 mangles some fonts, see section 4
`fonttools` 4.67.0	Live only; unused by `pypdf` 3.1.0, harmless
Not installed	`numpy`, `torch`, `transformers`, `open_clip_torch`, `Pillow`
Clone `~/.bashrc`	Aliases `py`, `py3`, `py315`, `python`, `python3`, `pip`, `pip3`, `pip315`, `py36`, `py38` now present (the `py` line was missing and added separately). Live's `~/.bashrc` lines 136-147 are the reference

Why the library copy was needed: the PyMuPDF wheel asks for GLIBCXX_3.4.19; the system libstdc++.so.6 (6.0.13, gcc 4.4) lacks it. The launcher runs Python through glibc 2.17's own loader with an explicit --library-path, which overrides LD_LIBRARY_PATH, so the fix is the path entry in the launcher, not an environment variable.

3. What was found and decided

numpy: stopped. numpy 2.5.4 (the only release supporting 3.15) refuses to build: "NumPy requires GCC >= 10.3"; devtoolset-9 is gcc 9.1.1. Routes round it: build gcc 10.3 on Live (hours), or build the wheel in the manylinux2014 container on the NUC (not confirmed that image has 3.15). Decision: leave numpy off 3.15. Only audio_features.py and AudioProcessor.py need it, and AudioProcessor.py also needs torch.
torch: no build. pip download --only-binary :all: torch on Live: "from versions: none". Likely no 3.15 build published yet (a fonttools cp315 glibc 2.17 wheel installed fine, so Live's pip does accept such wheels). Compiling it on CentOS 6 is not realistic.
pip build tips learned. (1) pip 26.2.1 no longer applies PIP_CONSTRAINT inside build environments; use --build-constraint FILE. (2) /tmp/pipc.txt held ninja<1.12 and patchelf<0.18; those versions have wheels for old glibc, which avoids building CMake. (3) Building CMake 4.4.4 from source fails: its bundled curl wants OpenSSL 1.1 headers, the system has 1.0. (4) Install packages one at a time; a failed build aborts the whole command.
Import audit corrected. The checkpoint _9 claim "only qwen_chat.py and the clap_* scripts need torch" came from a search that missed indented imports. MediaProcessor.py imports torch, open_clip and PIL inside a function (around lines 510-512, 561, 676) but does not import AudioProcessor or audio_features. AudioProcessor.py imports audio_features (numpy) at the top and torch, transformers, tokenizers lazily.
Which MySQL library. mysql.connector (9 files): IndexBuilder, ise_noindex, media_diag, MediaSearch, MiscIndexer, MiscSearch, orphan_check, pdf_duplicate_spotter, PDFsearch. pymysql (4): AudioProcessor, ise_noindex (uses both), MediaIndexer, MediaProcessor. Nothing in /bin imports either. Open risk: Live's 3.8 has connector 9.0.0, 3.15 has 26.7.0; only imports were checked, no real search through 3.15 yet.
Clone never indexes PDFs (operator's statement), so PDF tests belong on Live. Dev's /bin is hand-managed and out of scope. Dev stays on Python 3.8.18 (3.6 also there) with its 32-bit PyMuPDF 1.18.17; there is no 3.15 for 32-bit, and the planned 64-bit Dev rebuild is the route (it would then follow the Clone recipe above).

4. PDF comparison, Live, 5 PDFs (attach-93, 149, 150, 162, 172), 320 pages

Dry runs (--dry-run --limit 5); per-engine "total terms found / unique-to-that-engine":

Setup	PyMuPDF	pypdf
3.8 (PyMuPDF 1.18.17, pypdf 3.1.0)	63,265 / 1,330	63,444 / 1,509
3.15, pypdf 6.21.1, no fontTools	63,237 / 866	63,364 / 993
3.15, pypdf 6.21.1 + fontTools	63,237 / 2,064	62,842 / 1,669
3.15, pypdf 3.1.0 (adopted)	63,237 / 1,427	63,444 / 1,634

With pypdf 6 + fontTools, attach-162 produced run-on junk (spaces decoded as letters, e.g. words fused into one long string). That is why pypdf is pinned at 3.1.0; an unpinned upgrade brings it back.
With 3.1.0, pypdf output is identical to 3.8. PyMuPDF's whole vocabulary across the five PDFs is 8,365 distinct words on both versions, with 26 differing (13 each way), nearly all a word fused with or split from a footnote or page number. Conclusion: equivalent for practical purposes.
--monitor shows "0 unique words" in a dry run (no index is kept), so it cannot compare vocabularies. --single needs a real attachment number (an earlier run used the placeholder NNN and was rejected by the argument parser).
PDFIndexer.py v8.7.1 starts and runs under 3.15 on Live and Clone. The only patch needed to move PDF indexing is MegaIndexer.sh line 8 (python3.8 PDFIndexer.py --fast --monitor). Timing is the operator's call.

5. The 3.8 patch list (Clone's `/bin` is the master)

cmp confirmed indexall, indeximages and mediawatchdog are identical in Clone's /bin and /var/www/html/Collabware/bin.

File (Clone `/bin`)	Line(s) naming 3.8	Can it move to 3.15?
`indexall`	33 (`Check_Media_Classification.py`), 40 (`MediaIndexer.py`), 42 (`MediaProcessor.py`)	40 yes; 42 no (`torch`); 33 not yet checked
`indeximages`	90 (`Check_Media_Classification.py`), 95 (`MediaIndexer.py`), 96 (`MediaProcessor.py`)	95 yes; 96 no; 90 not yet checked
`mediawatchdog`	37 (`PY=${PY:-python3.8}`)	runs `MediaProcessor`, stays on 3.8
`audio_plan` (2), `audio_run` (1)	call `AudioProcessor.py`	no (numpy and `torch`)
`bin_compare_sysplex.sh`	9 (runs `/root/bin_compare`)	needs a 3.15 compatibility look
`mediawatchdog.md`	26, 39, 51	documentation wording only
`bin_deep_check.lst`, `sysplex_python_environment`	records, not commands	no patch

Differences from the list in _9: chkindeximages in /bin (157 bytes, 12 Oct) no longer names 3.8, while the Collabware/bin copy (165 bytes, 6 Oct) still does; coichecks exists only in Collabware/bin (Live line 5); indeximages2 is not on Clone at all. The ISE folder's MegaIndexer.sh (4, 8, 12) and MediaClassifier.sh (9, 11) are unchanged from _9. So indexall and indeximages would become mixed (3.15 for MediaIndexer, 3.8 for MediaProcessor); whether to split them that way is the operator's decision.

6. Open items, in order

Decide the 3.8 patching split (section 5); timing is the operator's call. Needs his real PDF cron lines (never seen; crontab -l on Live showed no Python lines, jobs run through MegaIndexer.sh).
Check Check_Media_Classification.py imports; run one real PDFsearch.py search through 3.15 to test the connector version gap.
Root's mailbox on Live (/var/spool/mail/root) has new mail twice this session; probably cron output, unread.
Still open from _8 and _9: backup copy of Clone's VM folder after a clean shutdown; the four old-IP /bin scripts on Clone (json_md5sums_all, copies_Dev_to_Clone, copies_Clone_to_Dev, scp.text); stale http:// links (grep -n boardurl /var/www/html/Settings.php); Dev's hostname output for the indexers' IS_DEV check; swap and /etc/fstab on Clone; what "do not index all that" meant; the parked list in _8 section 5, item 10.
Manual text still wrong: PDFIndexer.py tokeniser is described as a plain .split() (a regex tokeniser since v7.4); the "union rebuild" cron example is not a rebuild; the blank-page numbering quirk (page number one too low after a blank page) needs a --fresh rebuild to fix.
Scratch files on Live that can go: /tmp/cxx, /tmp/wh, /tmp/pipc.txt, /tmp/numpy*.log, /tmp/pdf*.txt, /tmp/mu*.txt, /tmp/mu_words.py.

7. Corrections and lessons from this chapter

I recommended installing fontTools; it made pypdf 6 worse on these fonts. Fixed by pinning pypdf 3.1.0.
I suggested --only-binary "numpy<2"; wrong, numpy 1.x has no 3.15 support.
I first said no 32-bit PyMuPDF wheel exists; true only for current releases. Old ones (1.18.17) have 32-bit builds, which Dev uses.
Do not give commands with placeholder text like NNN; give a real example value.
A pasted block whose first command prompts (such as cp asking to overwrite) swallows the rest of the paste.
Import audits must include indented (lazy) imports.
The first reply of a chapter should state the next step plainly; the operator prefers statements over questions.
