Once we get that sync'd, I consider it a non-issue. The wider question of caching parser output of older revs like we discussed the other day is way beyond the scope of this bug.

It didn't "melt the servers" :) As explained on bug 24124, when viewing a diff, the preview of content under the diff was being parsed on every diff view and not using the parser cache. When viewing a diff to the current rev, which is a very common scenario, I changed it in r69191 to use the parser cache. It's only a fix for a single scenario (diffing to cur), but it's a fairly common scenario in the enwp setup for FlaggedRevs so it should provide a noticeable difference. And it'll be generally useful whenever someone diffs to cur. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ Wikibugs-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikibugs-l
