UESPWiki:Upgrade 1.19 to 1.19.3

This article documents the upgrade procedure for MediaWiki 1.19.0 to 1.19.3.

Customized Files

Note that the following does not include extensions other than the ones included in a standard MediaWiki installation.

File	Changed in 1.19.3	Notes
includes/OutputPage.php	No	Modified to include advertising code
skins/monobook.main.css	No	Minor display tweaks (may not be needed)
skins/MonoBook.php	No	Modified to include advertising code
includes/logging/PatrolLog.php	No	Minor bug fix?

Note that since all customized files remain unchanged in 1.19.3 then we can just overwrite them (no manual merging of changes is needed).

Test Upgrade

• Backup current uesp_net_wiki5 database on content3 (exclude the objectcache table which seems to be causing the backup issues).
• Copy backup to new database uesp_net_wikitest.
• Copy just the structure of uesp_net_wiki5.objectcache to the test database;
• Copy current MediaWiki code to new folder, change to use new db and ensure it works (content3.uesp.net/w193).
• Upgrade files to 1.19.3.
• Run upgrade script (runtime = 23 sec on content3).
• Test to ensure it works.
• Issues Noted

• Write's don't work (edit and save doesn't work, no error message). Note that this appeared to be due to a misconfiguration of the test wiki (writes were going to the original database instead of the test database). A complete re-dump of the wiki db with a corrected LocalSettings.php worked fine.
