Platform/JS Compartments Mochitest

This page is a tracking page for getting the JS compartments work to pass xpcshell tests and Mochitests and other automated test suites.

How to get the patch queue

Install hg queues.

Then add to .hg/patches/.hg/hgrc

[paths]

default = http://hg.mozilla.org/users/mrbkap_mozilla.com/brain-transplants

Then go into .hg/patches and hg pull, hg up and then go back to ../../ and do hg qpush -a. Build. Every time we update the queue you have to do qpop -a in the repository, then pull and update the patch queue, and then go back and do qpush -a to get the patches applied again.

Mochitest

Run with python runtests.py --total-chunks=20 --this-chunk=n --autorun --debugger=gdb where n is the chunk you want to examine.

Remaining large-ish items

Post b7:

• document.domain (we currently don't revoke access to the document's original domain, we probably should do that).
• Error hacks?
• XPCSafeJSObjectWrapper::WrapObject() fails
  -> remove XPCSafeJSObjectWrapper
• Fix error messages for property access denied. Old message included two origins, new one doesn't, and it looks like we're not using any of the localization that the old message had. Error console should show both origins, exception message probably (?) shouldn't.
• Confirm that the fix in docshell/test/chrome/test_bug454235.xul is appropriate.
• We no longer support .wrappedJSObject on location and XMLHttpRequest. Confirm that it was ok to remove those from tests/js/src/xpconnect/tests/mochitest/test_bug553407.html.

FIXED issues:

• I allow named frames to be created on xray wrappers so parent[name] works.
• Fix up XrayWrappers
• Make chrome wrappers expose nothing by default
• added scriptOnly check to chrome object and make all XOWs script only
• Location object
• nsJSContext::BindCompiledEventHandler(), target and funobj from
• Components.utils.import() from non-chrome code.
• DocShell navigation tests
• XPCNativeWrapper.unwrap() different compartments
• IndexedDB and DOM worker tests, need cross compartment structured clone (jorendorff/bent)
• XPCNW holder objects vs JS_ClearScope()

• bent: I fixed test_pluginstream_newstream.html so that it will work, but the underlying cause is a change in our access denied exception messages, which needs to get fixed. Followup bug?
