Conflicting parser tests between extensions
by Antoine Musso 09 Jul '14

09 Jul '14

Hello, Ori and I attempted to run phpunit tests with all extensions deployed on the wmf cluster. With the help of Sam Reed we fixed must of the issues but there is one nasty one remaining. The parser tests expectations can not be meet when one mix extensions together. For example the Cite tests have some images/thumbnails, when one installs the MultimediaViewer extension, the test file because the generated output adds data-file-width="1941" data-file-height="220" to the <img> elements. That is due to MultimediaViewer registering the parser hook ThumbnailBeforeProduceHTML . And that is legit. I am looking for ideas to properly fix extensions altering output and thus breaking other extensions parser tests. A lame idea would be to have the Cite parser tests to unregister any hook altering HTML which are not registered by Cite. We could maybe come up with another repositories that has a different set of parsertests suitable for multiple extensions. There is a few more extensions having a similar issue such as ProofReadpage inserting class="prp-pagequality-1 in title links. Thoughts? == References == A bug for MultimediaViewer / Cite has some more details: https://bugzilla.wikimedia.org/show_bug.cgi?id=67302 We have a tracking bug to get all extensions pass unit tests together: https://bugzilla.wikimedia.org/show_bug.cgi?id=67216 An experimental run is: console: https://integration.wikimedia.org/ci/job/mediawiki-core-extensions-integrat… test report which highlight other issues: https://integration.wikimedia.org/ci/job/mediawiki-core-extensions-integrat… -- Antoine "hashar" Musso

HTML templating progress; Knockout Components & curly brace syntax
by Gabriel Wicke 09 Jul '14

09 Jul '14

Hi all, There are several new & exciting developments in HTML templating land. First of all, Ryan Kaldari kindly tested the Knockoff / TAssembly HTML templating library from a Mobile perspective [1,2], and summarized his findings on the wiki [3]. The main missing feature he identified was the ability to mark up control flow outside of HTML elements. To address this, I just added support for Knockout's comment syntax to the Knockoff compiler [4]. This turned out to be straightforward, and required no changes in the TAssembly runtime. Secondly, Dan spotted two very promising developments in upstream KnockoutJS: == Knockout Components == There's a new version of KnockoutJS coming that might bridge a gap we saw at the architecture summit in January, the one between templating and widget...ing. Knockout components [5,6] could be said bridge, they're basically web components but possible now. == Curly braces == The other thing they're adding is text interpolation so you can do <span>{{name}}</span> and people don't have to be sad about Knockout's HTML attribute syntax. This can simplify the migration for existing handlebars compatible templates as used by Mobile & Flow. The KnockoutJS release is currently in early beta [7], with the release expected later this summer.

Attention: Vagrant XDebug has changed!
by Yuri Astrakhan 08 Jul '14

08 Jul '14

If you have been using remote debugging in Vagrant, make sure you "enable-role zend". Otherwise your debugger will no longer receive any callbacks from Vagrant. This is due to the recent change to HHVM by default. There has been some ideas to allow both zend & hhvm to coexist at the same time on the same vagrant on different ports and be debuggable via the same xdebug interface, but that hasn't been done yet, nor is it known if it's possible. I learnt about it the hard way :(

Re: [Wikitech-l] learning Ops infrastructure (was: Re: 404 errors)

Thanks Sumana, That's good info to have. I'll look through those links. That diagram may make its way into the presentation that I'm drafting. The presentation has balooned to an alarming length already but I'm going to try to complete it in outline form before pruning. If someone else makes presentation slides available about infrastructure under a license that allows reuse I would greatly appreciate it. By the way, I appreciated the overview of UX in your keynote [1].

Forwarding to Wikitech-l. This HR office hour will follow the Language Engineering office hour. Because the new ED has a tech background there might be greater than usual interest in this WMF issue from those on the tech list, and those with lots of free time tomorrow can be present for both meetings.

Removing support for register_globals
by Legoktm 08 Jul '14

08 Jul '14

Hi, tl;dr: <https://gerrit.wikimedia.org/r/144854> stops supporting MediaWiki instances with register_globals enabled. When PHP 5.3 was released, register_globals was officially deprecated, and that was over 5 years ago[1]. It was then removed in PHP 5.4. Since MediaWiki still supports 5.3, we've had a check at the top of WebStart.php and in the installer to recommend disabling register_globals if it's still enabled. When working with configuration database-related things as well as general code review of extensions, I've noticed code that does isset( $wgFoo ) in an unsafe manner. We could fix those individual issues, but I think it would be easier to just stop supporting installs that have register_globals enabled. It's 2014! I've uploaded a patchset[2] that will disable any current installation that has register_globals enabled. It also modifies the command-line installer to prevent installation if it is enabled.

Study on the user base for the Memento MediaWiki Extension
by Shawn Jones 08 Jul '14

08 Jul '14

Hi folks, As we improve the Memento MediaWiki Extension, we also search for information on where and how it can be used. I had written a blog post last December talking about its use in helping users of fan sites avoid spoilers. [1] Recently, we’ve done a study using anonymized logs for the Wayback Machine and discovered that there are a potential 168,000 requests per day at the Wayback Machine that could benefit from use of the Memento MediaWiki Extension, 132,000 of those for Wikipedia alone.
