Project:Test reports

__NEWSECTIONLINK__ This is the place to report bugs for the beta cluster and track them.

If you find something that doesn't work as expected, make a note of it here. If you're comfortable entering bugs in and you think this is a bug in MediaWiki, then please do that as well. Add   just before the bug report with the bug number. Please sign your problem reports.

If you see that someone has reported a problem, but not filed a corresponding Bugzilla ticket and you think one is needed, then please file one for them and add   just before the problem report here.

If you file a Bugzilla report, it is often very useful to include links to any on-wiki discussion.

Javascript errors with Monobook skin
The error doesn't show up on the JS console with Vector.

Username doesn't stay logged in
I created User:Hexmode-test and when I log in with the user, the "you're logged in" page has "Log out" in the upper right hand corner, but navigating away from that page shows that I'm not logged in: "Log in" appears again in the upper right hand corner. Interestingly it doesn't happen with my current user or on Opera or Chrome. -- MarkAHershberger (talk) 01:54, 12 January 2012 (UTC)

Note that I thought part of this could be a caching problem: When I log out on Opera and the return to the previous page (not by using the "back" button, but by clicking on "Return to Problem reports.") the upper right shows "Log out" instead of "Log in". Reloading does show the correct thing, though. Upon further testing, though, this maybe the length of time to load the log out icon.

Further testing on FF shows that this appears to be a problem of a faulty cookie. Erasing all my cookies and the logging in keeps me logged in. -- Hexmode-test (talk) 03:05, 12 January 2012 (UTC)

mw.util.$content is null
This is about http://commons.wikimedia.beta.wmflabs.org
 * 1) mw.util is undefined when attempting to access from MediaWiki:Common.js without using mw.loader.load
 * 2) despite wrapping all inside   mw.util.$content is null. But it shouldn’t since the code wrapped inside   should be executed after mw.util is initialized. -- Rillke (talk) 22:17, 12 January 2012 (UTC)


 * Fixed. For more details see 33711. Krinkle (talk) 03:53, 14 January 2012 (UTC)
 * Fixed on enwiki too. -- MarkAHershberger (talk) 04:54, 14 January 2012 (UTC)
 * NOT FIXED. Just broke the half common.js . Just did  and got.
 * To reproduce the $content is null - problem, use Firefox 9.0.1 with Firebug, activate the script panel and in the console-panel click "stop/halt on all errors", then go to http://commons.wikimedia.beta.wmflabs.org/wiki/User:Rillke Shift+Reload. Debugger stops at

$.cookie not defined
I get the following Javascript error on http://en.wikipedia.beta.wmflabs.org:


 * Uncaught TypeError: Object function (selector,context){return new jQuery.fn.init(selector,context,rootjQuery);} has no method 'cookie'

Seems like jQuery's cookie plugin isn't initialized properly. NOTE: This seems only apparent when enabling the MenuTabsToggle gadget (which uses cookies). (It does work in the Commons test wiki.) — Edokter  ( talk ) — 14:19, 13 January 2012 (UTC)

More script errors (pointing to legacyWikibits) on enwiki: — Edokter  ( talk ) — 14:44, 13 January 2012 (UTC)
 * Uncaught TypeError: Cannot call method 'getParamValue' of undefined
 * Uncaught TypeError: Cannot call method 'wikiUrlencode' of undefined


 * Fixed. For more details see 33711. Short: Dependencies must be declared. Gadget likely already broke for some people in race conditions / bad luck / slow connection. Modules are loaded a bit faster now, making race conditions more important and lack of dependency declaration more visible. Fixed for that gadget on wmflabs here: http://en.wikipedia.beta.wmflabs.org/w/index.php?title=MediaWiki%3AGadgets-definition&action=historysubmit&diff=54891&oldid=21968 Krinkle (talk) 03:52, 14 January 2012 (UTC)

https does not work
Maybe not a MediaWiki bug, but all testwikis have no https support: https://labs.wikimedia.beta.wmflabs.org It is possible to enable https for the testwikis? Thanks. Umherirrender (talk) 19:21, 14 January 2012 (UTC)
 * Yes, it will be probably enabled during the week, but it's not a bug Petrb (talk) 11:15, 15 January 2012 (UTC)
 * Is there a chance to get it? Thanks. Umherirrender (talk) 20:01, 8 February 2012 (UTC)

Script does not run
Can anyone tell me why this does nothing on the labs Commons version? To be more specific, if I put in an alert in the third parameter, it will trigger the alert. If I use "jQuery.cookie" (note the case), I get "unknown dependency". Yet this code, either wit "jquery.cookie" or "jQuery.cookie", works perfectly on the real Commons. — Edokter  ( talk ) — 20:18, 14 January 2012 (UTC)


 * Hi, I assume because


 * does not work on Testwiki-Commons. This is because mw.util.$content is null and throws an error inside a $. Just try it yourself on the real commons:


 * and in testwikicase the error occurs in the common.js preventing all scripts that execute later from working properly.
 * Krinkle decided to undo commenting out the culprits and did not offer a response to the $content-null-problem. -- Rillke (talk) 22:12, 15 January 2012 (UTC)


 * Just try the following (run from a multiline-console (like firebug, IE developer tools)) and you'll see that jquery.cookie is loaded:


 * -- Rillke (talk) 22:20, 15 January 2012 (UTC)


 * It seesm $.cookie is not the problem; instead, mw.loader.using just fails. Anyway, since it is only a problem on the beta Commons, it should't be much of a problem. I am throwing it on a local config issue. — Edokter  ( talk ) — 00:24, 16 January 2012 (UTC)

css differences
 And in the rotation popup the font is different from the normal UI.      Commons: ".ui-widget {    font-family: sans-serif;"      beta:    ".ui-widget {    font-family: Verdana,Arial,sans-serif;"  And in the rotation popup the corners of the buttons and title bare are rounded - not so in the old Commons. That non-round corners match Monobook much better.  don't know the sources of the font differences - may be bad JS... however, they are there ;)  not sure if the same happens in vector

"Show preview" often only reacts to the second click
While editing, I noticed that clicking the "Show preview" button in the edit window often does not work the first time around, the preview is only shown after clicking the button again. This happened to me several times, but unfortunately I can't reproduce it right now and so can't investigate further. I'm using Firefox 9.0.1 on Ubuntu Oneiric. -- tbleher

ext.wikiEditor.toolbar.hideSig is loaded even when the toolbar is disabled
Seen on de.wikipedia.beta.wmflabs.org To reproduce this disable the WikiEditor toolbar in your preferences. The module ext.wikiEditor.toolbar.hideSig is still loaded, which doesn't hurt but is superfluous.

RL does not update the minified versions in an appropriate time
On http://commons.wikimedia.beta.wmflabs.org/wiki/MediaWiki:Common.js I even tried to delete & restore common.js but is simply does not update (except if you change your skin or language)

Just try it yourself. (e.g. with a new console.log-line)

I don't know whether this is specific to MW 1.19 or just the test-environment.

Old recent changes when not logged in
On this Wiki I don't see recent changes on Special:Recentchanges. I don't see any change after 19 january.
