PHP time limits
by Tim Starling 09 Sep '18

09 Sep '18

I noticed that WMF production accidentally had no PHP time limits. Possibly it has been like that for as long as three years. The HHVM configuration purportedly set the time limit to 60 seconds, but that did not take effect. I've deployed a change to set PHP time limits as follows: * 60 seconds for GET requests * 200 seconds for POST requests * 20 minutes for ordinary job queue jobs * 1 day for video scaler jobs If it really has been three years of no time limits, this change may break some accumulated assumptions. But note that Varnish times out waiting for Apache after 120 seconds, so for most requests longer than this, it would not have been obvious that HHVM continued to run, an error was delivered anyway. The logs so far show a trickle of timeouts from the parser, which is normal by historical standards. https://phabricator.wikimedia.org/T97192 -- Tim Starling

Google Code-in 2018: Mentor some smaller tasks for young contributors!
by Andre Klapper 07 Sep '18

07 Sep '18

<tl;dr>: Read https://www.mediawiki.org/wiki/Google_Code-in/Mentors and add your name to the mentors table and start tagging #GCI-2018 tasks. We'll need MANY mentors and MANY tasks, otherwise we cannot make it. Google Code-in is an annual contest for 13-17 year old students. It will take place from Oct23 to Dec13. It's not only about coding: we also need tasks about design, docs, outreach/research, QA. Last year, 300 students worked on 760 tasks supported by 51 mentors. For some achievements from last round, see https://blog.wikimedia.org/2018/03/20/wikimedia-google-code-in-2017/ While we wait whether Wikimedia will get accepted: * You have small, self-contained bugs you'd like to see fixed? * Your documentation needs specific improvements? * Your user interface has some smaller design issues? * Your Outreachy/Summer of Code project welcomes small tweaks? * You'd enjoy helping someone port your template to Lua? * Your gadget code uses some deprecated API calls? * You have tasks in mind that welcome some research? Note that "beginner tasks" (e.g. "Set up Vagrant") and generic tasks are very welcome (like "Choose and fix 2 PHP7 issues from the list in https://phabricator.wikimedia.org/T120336" style). We also have more than 400 unassigned open #easy tasks listed: https://phabricator.wikimedia.org/maniphest/query/HCyOonSbFn.z/#R Can you mentor some of those tasks in your area? Please take a moment to find / update [Phabricator etc.] tasks in your project(s) which would take an experienced contributor 2-3 hours. Read https://www.mediawiki.org/wiki/Google_Code-in/Mentors , ask if you have any questions, and add your name to https://www.mediawiki.org/wiki/Google_Code-in/2018#List_of_Wikimedia_mentors (If you have mentored before and have a good overview of our infrastructure: We also need more organization admins! See https://www.mediawiki.org/wiki/Google_Code-in/Admins ) Thanks (as we cannot run this without your help), andre -- Andre Klapper | Bugwrangler / Developer Advocate https://blogs.gnome.org/aklapper/

Change tag reading from the new column in the beta cluster
by Amir Sarabadani 06 Sep '18

06 Sep '18

Hello, As part of normalizing change tag schema [1] I just switched on reading from the new column (ct_tag_id in change_tag table, a foreign key to ctd_id from change_tag_def table) in beta cluster [2] which means new rows will have empty string as their value of ct_tag. [3] We are not rushing to flip the switch in production but I just wanted to send this email asking people who test in beta cluster to file a phabricator ticket if they see anything unexpected in there that might be related change tags. This table is being read if someone checks history, recent changes, watchlist, user contributions, or whole lot of other special pages plus lots of API queries. I checked anything I could think of but I might have missed something. Any extra pair of eyes would be extremely appreciated. [1]: https://phabricator.wikimedia.org/T185355 [2]: https://phabricator.wikimedia.org/T196671 [3]: For example: MariaDB [enwiki]> select ct_id, ct_rc_id, ct_rev_id, ct_tag, ct_tag_id from change_tag order by ct_id desc limit 10; +--------+----------+-----------+-----------------------+-----------+ | ct_id | ct_rc_id | ct_rev_id | ct_tag | ct_tag_id | +--------+----------+-----------+-----------------------+-----------+ | 217824 | 633991 | 384018 | | 3 | | 217823 | 633990 | 384017 | | 3 | | 217822 | 633989 | 384016 | | 3 | | 217821 | 633988 | 384015 | | 3 | | 217820 | 633987 | 384014 | | 3 | | 217819 | 633986 | 384013 | mw-undo | 2 | | 217818 | 633985 | 384012 | mw-undo | 2 | | 217817 | 633984 | 384011 | visualeditor-wikitext | 29 | | 217816 | 633983 | 384010 | mobile web edit | 16 | | 217815 | 633983 | 384010 | mobile edit | 15 | +--------+----------+-----------+-----------------------+-----------+ 10 rows in set (0.00 sec) Thank you!

Overriding MW core messages via extension
by James Montalvo 06 Sep '18

06 Sep '18

Is it possible to override messages part of MediaWiki core via an extension. I tried adding to an extension's en.json file and that didn't seem to work, but am wondering if there's another way. Is it possible for an extension to add a language? If so, then the extension's mylang.json file could only define those that need overriding and fallback on another language for everything else. Thanks, James
