Description Jamie Bliss 2005-06-21 21:01:02 UTC

If you are using a form of caching other than DB (memc, Turck, or eAccelerator),
the keys are dependent on the DB name. So if you have 2 wikis using the same DB
(with different prefixes), then their cache keys will overlap.

This isn't a problem when using DB cache because it using the table prefix.

My proposal to fix it would be to add $wgCacheKeyPrefix to DefaultSettings.php,
which defaults to &$wgDBname, then change all current code to use that (Or just
change the BagOStuff classes to prefix it).

Sensible thing would be to combine $wgDBname and $wgDBprefix.

Comment 2 Jamie Bliss 2006-05-27 05:14:00 UTC

Still a problem in ParserCache.php and in LinkCache.php.

Comment 3 Rob Church 2006-11-21 16:47:07 UTC

This was fixed in r16791.
