[regression] page loaded via file:// uses XHR for dojo.require() to CDN, should use script-io

[Ruth Lang]

When starting a html file locally which includes PraseOnLoad?=true then Firefox brings an error "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE)". The same file works fine with IE9 and Opera. and when using Dojo 1.6 it works well with Firefox too. I have attached two html files test_16.html and test_17.html.

When I change "dojo.js" to "dojo.js.uncompressed.js" I can see that it's trying to do a XHR to get TitlePane.js... so that's a bug, it should be trying to get it via script-io, since it's going to CDN, right?

A weird thing the test case is doing though is to pull in the file with the dojo.require() calls via a <script> tag. IIRC that's something that we've fixed since the 1.7.0 release, and will be in the 1.7.1 release.

According to Rawld, this should be fixed with the recent changes for other bugs such as #14394 or #13183.

I'll test this on a 1.7 branch build, but expect to not be able to reproduce it at this point.

[Kenneth G. Franqueiro]

I am actually unable to reproduce this with the attached files, even as-is against Google CDN 1.7.0. Even tried FF 3.6 for good measure.

Rawld, were you able to reproduce this with the attached files? If so, on what browser version?

[bill]

This reproduced for me. Simply:

1. download test.zip and unzip
2. load ​file:///Users/bill/Downloads/test/test_17.html in firefox. Your path may vary but be sure to use ​file://
3. check firebug console

I reproduced on mac.

[Kenneth G. Franqueiro]

Oops, I should have interpreted this as meaning using file URL. Yes, I can reproduce it against Google CDN, and can still reproduce it against a build with the latest 1.7 branch files. Looks like this is not resolved with the other fixes that have gone in.

Rawld, I guess this is still hitting the sync code path for some reason. Given that we generally discourage people from running scripts from file:// URLs anyway, I'm not sure how high-priority this should be, but the test case makes it evident that it worked with 1.6 and doesn't with 1.7. Any idea how tough this would be to track down?

simplified (single file) test case

These didn't make it into the 1.7.1RC, so bumping them to 1.7.2 (as stated in the email I sent yesterday).

[Rawld Gill]

This problem has the same root cause as indicated in #14459 and was repaired in [27763]; see ​http://trac.dojotoolkit.org/ticket/14459#comment:7 for details.

test_17.html works against a dojo built with cdnBuild.sh and simulating xdomain (after 27763).

Thanks for the test bill!

[Ruth Lang]

Problem still exists with 1.7.2 and CDN

test for Dojo 1.7.2

[bill]

I tried file:///Users/bill/Downloads/test_172..html (your path may vary but use file://), and it's grabbing TitlePane.html via XHR, so still seems broken to me too.
