Bugs, Repairs, and Internal Operational News

Considerable editing issues presented themselves to users around the world for more than an hour on December 25 (wikitech-l). Between 18:50 and 20:20 UTC, edits were lost on a number of Wikimedia sites, although the problem was resolved cleanly on most, including the English Wikipedia. Only the Hebrew Wikipedia suffered lasting problems beyond the 90-minutes within which most problems were resolved on almost all sites. The glitch highlights the challenges of maintaining the stability of a website with as many visitors as Wikimedia sites over holiday periods when volunteers are few on the ground.

Another, unrelated issue, also came to light on Christmas Day. Bug #26429 ("Fatal error: PPFrame_DOM::expand") blocked a number of actions on the English Wikipedia, and quickly generated reports from a number of WMF wikis. Fortunately, the error only temporarily blocked editing and was worked around by reloading the page; it was reported as fixed on the afternoon of 26 December (UTC).

Not all fixes may have gone live to WMF sites at the time of writing; some may not be scheduled to go live for many weeks.

• With the resolution of bug #26412, [edit] links are no longer shown alongside the header on search pages, which are not editable by their very nature.
• A new module has been added to the MediaWiki API. QueryPage; it allows users to generate the output of certain "query"-based special pages in a machine-readable format, rather than via HTML screen-scraping (bug #14869).

Although it's not live yet, bugzilla:5899 seems worthy of inclusion as a brief note. guillom 10:27, 27 December 2010 (UTC)[reply]

Hmm... Sounds exciting. Do you know if anything's actually changed with it this week though? Anyway, now it does have a mention - I'm sure everyone reads the comments section :) - Jarry1250 ^{[Who? Discuss.]} 17:59, 27 December 2010 (UTC)[reply]

Right. I always forget the comments are actually the talk page, transcluded :) guillom 15:12, 28 December 2010 (UTC)[reply]

Just as a note, the PPFrame error didn't really block editing since it only intermittently appeared, and was gone if you reloaded the page. Bawolff (talk) 06:29, 29 December 2010 (UTC)[reply]

Only the Hebrew Wikipedia suffered lasting problems beyond the 90-minutes within which most problems were resolved on almost all sites. - depends on what you call "lasting". Problems with the lost edits being cached and messing up page histories persisted for 12 hours at least. --Tgr (talk) 22:21, 1 January 2011 (UTC)[reply]
