2. Debian 9
3. Caddy

Database Hacking

We need to upgrade a really old version of mediawiki and will likely need to futz with the database.

1. Migrate to postgresql?
   1. make a git repo to store migration sql and other sql used for massaging the database contents
2. Delete old passwords (md5 with no salt) and expire all user passwords?
   1. Write/publish public sql script to clean up the production database for public publishing
3. Clean the database of spam/cruft?
   1. publish these scripts to the same sql script repo

MediaWiki-Vagrant

This potentially is a good environment for testing and migrating the database: https://www.mediawiki.org/wiki/MediaWiki-Vagrant

(more OpenStack Semantic MediaWiki images: https://wikitech.wikimedia.org/wiki/Portal:Cloud_VPS)

You'll need to follow this guide to get a dump of our database up and running: https://www.mediawiki.org/wiki/Manual:Moving_a_wiki

Password Rollover

We need to delete the password column and expire everyone's password. The old mediawiki only stores md5 hashed passwords with no salts, so we'll have to delete the whole thing

user_password_expires

MediaWiki version: ≥ 1.23

Date when user's password expires; null for no expiration date. Can also be set manually by calling User->expirePassword().
