mediawiki-1.16-to-2.24.2 upgrade

16 may 2015

mediawiki, php

today my wiki at [1] went south because the 1.16 version didn’t work with the very recent PCRE library used in php.

the error was something like:

Warning: preg_replace(): Compilation failed: group name must start with a non-digit at offset 4 in /home/patjk/public_html/speedsolving/wiki/includes/MagicWord.php on line 851

so as i’m on nixos, let’s see what pcre version is used by php:

as it turns out it was 8.37 and the version is supposed to be starting from pcre 8.34 onwards.

anyway, the update took 2 hours since i also had to fix my custom mediawiki theme called clean.

thanks to #mediawiki folks on irc.freenode.net for their support!
