Bugs, Repairs, and Internal Operational News

Software updates

This week saw a major code update, including changes for how MediaWiki handles file uploads and new Upload API capabilities that work with the Firefogg extension for Mozilla Firefox. As part of the updates, the cite features have been updated to allow list-defined references.

Bugs resulting

The software changes resulted in a number of bugs, and caused the pywikipedia Python library used by bots to break. [1] As a result, bots stopped working for a few days.

According to Kozuch [2], major bugs resulting from the updates have been:

Uploading new version of file fails (bugzilla:20677)
Commonist upload tool stopped working – errors at upload
AWB experiencing ongoing problems (WP:AWB/B). Due to changes in the MediaWiki Software, the current release (4.6) has been broken, and due to some other discovered bugs, a fix cannot be implemented and rolled out as of yet. ApiEdit (4.9) versions work fine.

Compatibility problems were discovered in the Usability Initiative's new edit toolbar, when it was used with Internet Explorer. Due to the bug, developers disabled the new edit toolbar for a few days while the bug was resolved.

Bots approved

Two bots were approved this week: HerculeBot 2, for the transfer of interwiki links from redirects to redirect targets, and Yobot 8 to assist with a previously approved task. There are a number of outstanding requests for bots, which anyone is free to comment on.

New features

File renaming has been enabled for admins. [3]

Other

The tech team is to add full TIFF support in the near future. This support will help MediaWiki render TIFF images (an image format widely used by museums, archives and in scientific research) so that users can view them in their browsers with a reasonable load time. [4]

==Technical issues and file renaming== According to the Techblog, several of the Commons issues resulting from the recent upgrade have been resolved, and there is now a call to check and make sure everything is working properly again. In addition, File renaming for admins has been re enabled after being disabled for several months (there was some sort of issue with it here on en.WP after enabling, but that has been resolved). One last note, a feature and extension deployment list is now being maintained on the Wikitech wiki[5].
