SourceMap on Google is broken

Description

http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.map

That file is incorrect for the url it's at. It's referencing the source, http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery-2.0.0.js, which is a 404.

This soucemap looks like it was built for http://code.jquery.com/jquery-2.0.0.js.

See: http://sourcemap-validator.herokuapp.com/validate?url=http%3A%2F%2Fajax.googleapis.com%2Fajax%2Flibs%2Fjquery%2F2.0.0%2Fjquery.min.js

I provided the file to Google as jquery-2.0.0.*, the sourcemap would need to be edited manually by Google to retarget the file name. Paul, did you guys do that last time? Or did I provide you one? The ASP.NET CDN uses the name name as we do with the embedded version so it doesn't affect them.

Looks like I did the job manually for 1.9.1 and sent them both (with and without version) but it didn't get into the build process; I wasn't sure which one they were using. So as I understand it from Google this can't be fixed, you'll need to use a local copy if you need the sourcemap.

So just in case it's not clear, this will be fixed by us in 2.0.1, but the current Google CDN version cannot be changed.

Whoops, just heard from them. They *are* changing the map, but whether you get it or not will depend on whether you or any intervening proxy has cached the old one forever.

FWIW, it seems my validator is able to fetch the right map from Google, but it appears 100% wrong. No idea how it's mapping every token up incorrectly. It's almost like it was built before the comment at the top of jquery.js was added.

Hah, I've noticed the map file generated points to jquery.pre-min.js instead of jquery.js...

I'll look into it.

milestone: 2.0.1 → 1.10/2.0

Also, the spec changed so we should change the pragma accordingly to //# sourceMappingUrl

Hmm, I see the spec was updated May 16th. Is there a discussion around that I can follow?

Nice, thank you.

Yes, the -git versions need to have working map files so thanks m_gol. I think it's too early to change from //@ to //# but let's do that for 1.11/2.1 time frame. If Chrome hasn't changed to accept the new format by then, our change will be a motivator for it.

Changed May 22, 2013 01:19PM UTC by m_gol comment:12

Seems reasonable to wait for a pragma change until 1.11/2.1.

I submitted a pull request: https://github.com/jquery/jquery/pull/1275

I really need people to test it before we ship 1.10, this all is way too fragile.
