Registering PHPUnit tests from third party libraries
by Jeroen De Dauw 05 Apr '13

05 Apr '13

Hey, I have some extensions that make use of non-MW dependent PHP libraries. These libraries come with PHPUnit tests that can be run as standalone. I'd like them to be run together with the tests for my extensions making use of them whenever I run them using phase3/tests/phpunit/phpunit.php. So far I have been doing this by registering the tests via the UnitTestsList hook as if they where regular extension tests. This is not ideal though since then I need to maintain this list of tests and make sure I update it whenever the third party library changes. The library itself does not provide a list of test files, as it's runner just runs everything in the relevant test directory, much like as MW does for core tests. Clearly that is not ideal, so I am looking for a way to not have to maintain such lists. Is there a way to register a whole directory so that the MW phpunit.php script runs all the tests in it? Cheers -- Jeroen De Dauw http://www.bn2vs.com Don't panic. Don't be evil. --

Taking out the garbage
by Chad 05 Apr '13

05 Apr '13

Hi all, tl;dr: I've cleaned up the mediawiki/core repo, and performance for fetch/clone operations should be noticeably faster. So, due to some recent upgrades in Gerrit, we've now got GC support in JGit as a result. Gerrit supports this functionality, which will greatly reduce the size of our repositories on-disk. It also makes use of an improved bitmap algorithm for fetches & clones, making them wayyy faster. I've now run this on mediawiki/ core, and the repo went from 3.0G down to ~620M on disk. You should now notice all read actions (over https & ssh) to be way faster--a fresh clone should now only be limited by your bandwidth, not how fast Gerrit can serve the repo from disk. If you notice *any* problems with mediawiki/core, please let me know immediately. If everything looks good, we'll set this up as a cron to run weekly or something for all repositories. -Chad

User signature time wrapped in a span
by Cyril 04 Apr '13

04 Apr '13

I recently tried to create a small javascript to parse user signature times on talk pages [1]. With it the readers would have been able to see the signature's timestamp in their preferred timezone (and as a side effect it would be consistent with the revision history) without breaking caching. The main problem I had was that MediaWiki didn't provide a class attribute wrapping the date nor the whole signature. There is a bug report on that topic: https://bugzilla.wikimedia.org/show_bug.cgi?id=25141 After some time spent looking for a system message it seems the only solution is to edit includes/parser/Parser.php. I added a span with a class at this line: https://gerrit.wikimedia.org/r/gitweb?p=mediawiki/core.git;a=blob;f=include… It works fine (at least in my own - limited - case). Some questions related to what I've done: - Would it be possible to wrap dates, or at least signatures in a class, as suggested in bug #25141? it may be useful for others too -- or perhaps to have a system message for dates (I'm not sure it's a good idea) - Is Parser.php the good place for that? - Would a similar solution see its way into MediaWiki some day? or are there problems I'm not seeing? (I'm not suggesting my script would be it, it's a quick and dirty hack created with very limited knowledge.) [1] using Moment.js <http://momentjs.com/>

They will be 'eventually consistent' - the categories aren't saved immediately as you hit the 'save' button but will be saved on next sync, whenever Android decides that is. We're getting closer to a full v1.0 release - user account creation and a bit more polish ought to do it.

Mobile caching improvements are coming
by Max Semenik 02 Apr '13

02 Apr '13

Hi, we at the mobile team are currently working on improving our current hit rate, publishing the half-implemented plan here for review: == Current status == * X-Device header is generated by frontend Varnish from user-agent. * There are currently 21 possible X-Device values, which we decreased to 20 this week. * X-Device is used for HTML variance (roughly, Vary: X-Device). * Depending on X-Device, we alter skin HTML, serve it full or limited resources. * Because some phones need CSS tweaks and don't support media queries, we have to serve them device-specific CSS. * Device-specific CSS is served via separate ResourceLoader modules e.g. mobile.device.android. == What's bad about it? == Cache fragmentation is very high, resulting in ~55% hit rate. == Proposed strategy == * We don't vary pages on X-Device anymore. * Because we still need to give really ancient WAP phones WML output, we create a new header, X-WAP, with just two values, yes or not[1] * And we vary our output on X-WAP instead of X-Device[2] * Because we still need to serve device-specific CSS but can't use device name in page HTML, we create a single ResourceLoader module, mobile.device.detect, which outputs styles depending on X-Device.[2] This does not affect bits cache fragmentation because it simply changes the way the same data is varied, but not adds the new fragmentation factors. Bits hit rate currently is very high, by the way. * And because we need X-Device, we will need to direct mobile load.php requests to the mobile site itself instead of bits. Not a problem because mobile domains are served by Varnish just like bits. * Since now we will be serving ResourceLoader to all devices, we will blacklist all the incompatible devices in the startup module to prevent them from choking on the loads of JS they can't handle (and even if they degrade gracefully, still no need to force them to download tens of kilobytes needlessly)[3] == Commits == [1] https://gerrit.wikimedia.org/r/#/c/32866/ - adds X-WAP to Varnish [2] https://gerrit.wikimedia.org/r/55226 - main MobileFrontend change [3] https://gerrit.wikimedia.org/r/#/c/55446/ - ResourceLoader change, just a sketch of a real solution as of the moment I'm writing this Your comments are highly appreciated! :) -- Best regards, Max Semenik ([[User:MaxSem]])

Bugday today (16:30 - 20:30UTC) on Skin and page rendering issues
by Andre Klapper 02 Apr '13

Hi, a quick reminder that today is a Wikimedia Bugday: Tuesday, April 02, 16:30-20:30UTC [1] in #wikimedia-office on Freenode IRC [2] This time we're in #wikimedia-office instead of #wikimedia-dev. Everyone is welcome to join, and no technical knowledge needed! It's an easy way to get involved in the community or to give something back. This even is part of a weekly QA activity [3], so we encourage you to triage throughout the week and record your activity on the bug day etherpad [4]. This information and more can be found here: https://www.mediawiki.org/wiki/Bug_management/Triage/20130402 For more information on Triaging in general, check out https://www.mediawiki.org/wiki/Bug_management/Triage Looking forward to seeing you there! andre [1] Timezone converter: http://www.timeanddate.com/worldclock/converter.html [2] See http://meta.wikimedia.org/wiki/IRC for more info on IRC chat [3] https://www.mediawiki.org/wiki/QA/Weekly_goals [4] http://etherpad.wmflabs.org/pad/p/BugTriage -- Andre Klapper | Wikimedia Bugwrangler http://blogs.gnome.org/aklapper/

Observations from putting together the RC
by Mark A. Hershberger 01 Apr '13

01 Apr '13

I put together the 1.21.0rc1 this afternoon. I'll announce it shortly, but, first, some observations. * When you add or remove a configuration variable, it should have release notes. When you update the release notes, please make sure that you also update MW.o. A number of variables are mentioned in the release notes that don't have a corresponding page on MW.o. The following configuration variables are the currently redlinked on <https://www.mediawiki.org/wiki/Release_notes/1.21>. If you can update their on-wiki documentation, I (and I'm sure others) would appreciate it. ** $wgBug34832TransitionalRollback ** $wgEnableCanonicalServerLink ** $wgPageInfoTransclusionLimit ** $wgMaxShellWallClockTime ** $wgShellCgroup ** $wgSquidPurgeUseHostHeader ** $wgDebugAPI ** $wgAPIGeneratorModules * Should the breaking changes be consolidated to a single section of the release notes? Right now, they are in three different sections. I think they should be moved to the top of their section at the very least (I did this on-wiki). * There remains one pending change that is not in the 1.21 release candidate -- "Password Recovery system uses Tokens" -- because it hasn't been merged into core yet. This change will probably have to wait until 1.22, but I'll leave it on https://www.mediawiki.org/wiki/MediaWiki_1.21 for now. -- http://hexmode.com/ [We are] immortal ... because [we have] a soul, a spirit capable of compassion and sacrifice and endurance. -- William Faulker, Nobel Prize acceptance speech
