[Wikitech-l] Diff hell

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 We've been getting a *lot* more complaints about bad diff renderings in the last couple days, which may be related to the recent upgrade of the wikidiff2 extension (triggered by PHP upgrades on the Fedora servers). Some notes on my quest to track it down: https://wikitech.leuksman.com/view/Diff_hell I don't have a lot of data points, but: * 1000 test hits total * all hits used wikidiff2 extension * 515 hits were to Fedora machines * 8 Fedora hits gave bogus results * quick command-line-based tests didn't have any failures The Ubuntu boxes are running a slightly older version of wikidiff2 which doesn't add the inline classes, but that shouldn't make any difference. - -- brion vibber (brion @ wikimedia.org)
