Update jQuery

[Rob Hudson]

A new jQuery has been released with some nice performance improvements:

[Rob Hudson]

Trac wouldn't accept my patch because of the file size (278k?). You can find a diff on my github repo:
​http://github.com/robhudson/django/tree/jquery-1.4.3

Maybe better use CDN hosted copy of jquery instead of including it in distribution?

[Jannis Leidel]

Using a hosted version seems not like a good idea given potential uses of Django in intranets etc. Updating jQuery seems reasonable though.

[Rob Hudson]

Agreed that a hosted version would be bad for offline scenarios.

Attaching a patch for 1.4.4 which just came out...

[Rob Hudson]

Oh right... diff is too big. See github: ​https://github.com/robhudson/django/tree/jquery-1.4.4

Careful, there is one "Backwards-incompatible changes in jQuery 1.4.4": ​http://blog.jquery.com/2010/11/11/jquery-1-4-4-release-notes/

width() & height() no longer return 0 for hidden elements.

​http://ejohn.org/blog/learning-from-twitter/ describes another funny side effect that we should test thoroughly before upgrading

jQuery 1.5 was released yesterday :)
​http://blog.jquery.com/2011/01/31/jquery-15-released/

This is not critical for 1.3 but certainly worthwhile for 1.4.

[Jannis Leidel]

jQuery 1.6 was released: ​http://blog.jquery.com/2011/05/03/jquery-16-released/

as the attachment file size limit applies for the patch, find it here: ​http://dl.dropbox.com/u/9067878/Django/14571-r16351.diff
it has jQuery 1.6.1 now included and the deprecated/changes functions adjusted

[Julien Phalip]

I've just talked to jezdez on IRC and we agree that it is too risky to upgrade jQuery at this stage, now that we're approaching the end of the 1.4 release cycle. Where it may bring negligible performance improvements, it may also break existing code. In the absence of a proper JS testing framework we're not willing to take that risk for the moment. The situation can be reassessed after 1.4 ships.

[Claude Paroz]

Now would be a good time to update jQuery. What about the version? Either the latest 1.6 (1.6.4) or the latest 1.7.2.

[Claude Paroz]

Unless someone opposes, I will update the patch to current 1.9.1 version of jQuery and commit it (as long as all current Selenium tests pass). The forthcoming sprint might also be a good opportunity to test/fix JS issues.

Fixed #14571 -- Updated embedded jQuery from 1.4.2 to 1.9.1

Thanks dArignac for the initial patch.

[Tim Graham]

I think this should be mentioned in the release notes as well as ​https://docs.djangoproject.com/en/dev/ref/contrib/admin/#jquery

[Claude Paroz]

Agreed for updating the linked docs. I grepped the release notes, and found no mention of jQuery at all, that's why I didn't touch them. But if you think it's worth noting, I can do it.
