Bug #: 30825
Summary: IE7 AJAX breaks with protocol-relative URLs on commons
Product: MediaWiki
Version: unspecified
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: Javascript
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected]
Classification: Unclassified
IE7 generates "access is denied" errors when attempting to load a URL of the
form "//commons.wikimedia.org/w/api.php?foo" using xhr.open within jQuery.
This means two things:
1. The AJAX call never returns useful information, so the features dependent on
it break.
2. JS-heavy pages break when JS execution stops on the error. Currently, this
is preventing UploadWizard from working in IE7 on live commons. It does work
IE6 and IE8 (even in IE7 compatibility mode).
You can see the error by visiting
http://commons.wikimedia.org/wiki/Main_Page?debug=true with IE7 while not
logged in. You can also try visiting UploadWizard while logged in, but some
confluence of IE bugs prevents the errors from appearing there when debugging
with MS Script Debugger is enabled.
If you need to see the problem in UW specifically, I can provide the convoluted
recipe for making the debugger work there too, but most likely fixing the
errors on Main_Page will fix it as well.
What seems to happen, AFAICT, is that scripts are included from
MediaWiki:Common.js using importScript(). This appends a new <script> tag to
the page, but because of how .append() is implemented in jQuery, also triggers
loading and executing of the script via AJAX. This is the point where it breaks
in IE7, although other browsers don't have a problem.
It's possible that the loading of many JS assets from bits.wikimedia.org is
part of the problem, since the AJAX requests then break the same-origin policy.
However, it works fine in Chrome and Firefox (and, oddly, IE6).
