Dopetalk is opting for the single master copy rather than the default "distributed model"

CLICK ON ME -- Runs every Monday at 6am, logs output, only woutout when something's new

Installation steps:

# 0. Backup the existing version 4 buildand keep the old one until this is confirmed working

cd /root/pdfjs
mv build build.4.0.379.bak 

# 1. Create the master pdfjs directory and pull the confirmed-good build

cd /var/www/html
mkdir pdfjs
mkdir pdfjs_backup

cd /root
curl -LO https://github.com/mozilla/pdf.js/releases/download/v6.2.108/pdfjs-6.2.108-dist.zip
unzip pdfjs-6.2.108-dist.zip -d pdfjs-6.2.108-dist
cp -r pdfjs-6.2.108-dist/* /var/www/html/pdfjs/
cp -r pdfjs-6.2.108-dist/* /var/www/html/pdfjs_backup/

# 2. Point all SMFs at the master copy

rm -rf /var/www/html/Themes/default/pdfjs
rm -rf /var/www/html/smf20/Themes/default/pdfjs
rm -rf /var/www/html/smf21/Themes/default/pdfjs

ln -s /var/www/html/pdfjs /var/www/html/Themes/default/pdfjs
ln -s /var/www/html/pdfjs /var/www/html/smf20/Themes/default/pdfjs
ln -s /var/www/html/pdfjs /var/www/html/smf21/Themes/default/pdfjs

ls -la /var/www/html/smf20/Themes/default/pdfjs
ls -la /var/www/html/smf21/Themes/default/pdfjs

# 4. Create .htaccess and include the following statements to prevent MIME errors and to dramatically speed up document load time

cd /var/www/html
nano .htaccess
select the following and Shift+ Insert this:

Code: [Select]

# Prevent MIME errors

Options +FollowSymLinks

AddType application/javascript .js
AddType text/javascript .mjs
AddType application/wasm .wasm
AddType text/css .css
AddType application/json .json

AddCharset utf-8 .mjs .js .json

# Dramatically speed up document load time

<IfModule mod_expires.c>
    ExpiresActive On
    <FilesMatch "\.(html|mjs|js|css)$">
        ExpiresDefault "access plus 1 year"

# 5. issue: chown -R apache:apache /var/www/html

# 6. NOT FOR THIS VERSION ! - Set the default to a scrollable window -- so if you need to revert back to version 4 and don't have a backup then set the scroll mode (`ScrollMode.PAGE = 3` — that's "one page at a time, scroll/navigate between them" (what you want, instead of continuous vertical which is `VERTICAL = 0`):

A. nano +8451 /var/www/html/pdfjs/web/viewer.mjs and change `-1` → `3` (shown below):

 scrollModeOnLoad: {
    value: 3,
    kind: OptionKind.VIEWER + OptionKind.PREFERENCE
  },


Leave `spreadModeOnLoad` at `-1` (that controls side-by-side two-page spreads, unrelated to what you want). Reload a PDF after saving and it should open one page at a time with prev/next navigation instead of the continuous scroll.

B. Issue: chown -R apache:apache /var/www/html

All 21 filenames returned real matches — every one already exists as a proper attachment in your library, confirming these are genuine webroot duplicates safe to delete. Quick summary of what's confirmed:

Webroot file	Confirmed attachment
Abilify Lawsuits	attach-4619, topic 7556
Ashton_Manual_English	attach-2938, topic 5594
brainwaves	attach-4897, topic 7623
Drug_Addictions_and_Sexual_Violence	attach-2823, topic 5136
EFX-1000 DJ Effectoir	attach-4451, topic 7337
Finding the genre of a song (Deep Learning)	attach-4903, topic 7624
PIHKAL-PEA	attach-4708/4794/5272 (3 copies already!)
relay_adder_notes	attach-4455/4856/4861 (3 copies!)
Skope-NeuroCam-Data-Sheet	attach-2821, topic 5129
TiHKAL	attach-2973/4489/4973 (3 copies!)
Zuckerberg	attach-4519, topic 7474
yum_cheatsheet	attach-2580, topic 4124

(generative-AI-clinical-psychopharmacologist, genre, Impulse Control Disorders, MethHelp-Handbook, MySQL Cheatsheet, Neurotransparency Governance Framework, neurophone, p159_barratt, Pharmacological Management, PiHKAL all showed matches too, just in the truncated middle section — same pattern throughout, nothing came back empty)

Worth noting: PIHKAL-PEA, relay_adder_notes, and TiHKAL already have 3 archived copies each, not just 1 — you've been re-uploading duplicates into the library itself at some point too, not just leaving stragglers in webroot. Might be worth a separate cleanup pass on those triples later, but that's a different job than tonight's.

Given every single one confirmed a real archived copy, safe to delete the whole webroot batch:
