Hi,

This adds a "--yui-cdn" option to serve-branches that will make Loggerhead serve the YUI files from Yahoo's CDN on http://yui.yahooapis.com/ instead of its local copy.

I added a yui_url method to BranchWSGIApp, similar to static_url, only...for the YUI files.

I tried it and it works, but that's about it.

Potential issues:

* Where should I have added the argument to BranchWSGIApp.__init__? I put it at the end. Should I have done that at all? Should I have used the 'config' argument or something instead?

* Whenever Loggerhead's copy of YUI is updated to a new version, the URL in BranchWSGIApp.yui_url will also need to be updated. Is anybody going to remember? :P

* I didn't add it to start-loggerhead. Do we care about that anymore?

* I didn't add any tests. To tell the truth, I lost interest while figuring out the config stuff. :P

* When Google's CDN gets a copy of YUI 3, I'll want to add support for that. I'd probably do it by changing the "--yui-cdn" argument to "--yui-cdn={google,yahoo,none}", which would break backwards compatibility. Do you want me to change it to "--yui-cdn={yahoo,none}" now so that won't be an issue?

* It still loads the individual files when using Yahoo!'s CDN. It would be more efficient to load the combined file, but, well, that would take more code. :P

Hmm, I think that's like 2 issues for every line of code I added. Maybe it's not worth it. :P

I actually really like this idea.
The only weird thing is that we're hard-coding the URL for yahoo in python itself. I can't really think of a much better way though, so I'm inclined to approve this.
Let's see if Michael es as crazy as I am :)

(I sent this via email 20 minutes ago, but LP seems to have ignored it, so I'll add it via the web now. Sorry if it results in a duplicate.)

There's a new version up (though LP hasn't mirrored it yet):

<http://bzr.mattnordhoff.com/bzr/loggerhead/yui-cdn>
<http://bzr.mattnordhoff.com/loggerhead/loggerhead/yui-cdn/changes>
<http://bzr.mattnordhoff.com/loggerhead/loggerhead/yui-cdn/revision/323>
<http://bzr.mattnordhoff.com/loggerhead/loggerhead/yui-cdn/revision/324>

Upside:

* When using the YUI CDN, it'll load one combined script instead of N individual ones.

* The BranchWSGIApp.yui_url function is gone.

Downside:

* It's evil and depraved.

And I meant to add:

You can really pick any of the 3 different versions. They all work; they're just varying levels of different kinds of evil. :)

Get rid of BranchWSGIApp.yui_url. Use YUI's combined JS file when using the CDN.

This is uglier, but it's better to use the single file (probably).

324. By Matt Nordhoff

Disgusting, evil template code to avoid repeating the list of YUI modules.

325. By Matt Nordhoff

Simplify the markup slightly

326. By Matt Nordhoff

Revert back to the simpler version with the yui_url method

327. By Matt Nordhoff

Rename --yui-cdn and use_yui_cdn to --use-cdn and use_cdn, respectively

328. By Matt Nordhoff

Badly-written NEWS entry. :D
