1238769 - Add a -xpcshell option to Firefox

Status: RESOLVED FIXED

(Firefox :: General, defect)

Description

[Mike Hommey [:glandium]]

Now that xpcshell is just a (literal) shell around XRE_XPCShellMain, we can actually just make Firefox itself work as the xpcshell.

Big facepalm on my part. Trivial change to make it build on all platforms.

So is this supposed to do something now?

firefox -xpcshell toolkit/components/autocomplete/tests/unit/test_finalCompleteValue_forceComplete.js

It just produces no output and finishes.

It works for me on Linux, but I can reproduce on Windows. Unfortunately, I can't tell why it does that. Following with a debugger says it exists through https://dxr.mozilla.org/mozilla-central/rev/ae7413abfa4d3954a6a4ce7c1613a7100f367f9a/js/xpconnect/src/XPCShellImpl.cpp#1593
Bobby, any ideas? (this should probably be filed as a separate bug)

FWIW, I was testing on linux (though with a nightly, not a local build).

That must means that something in ProcessArgs threw an exception or otherwise caused us to return false. You'll need to step into that function to get to the source.

I was hoping to use this functionality in https://bugzilla.mozilla.org/show_bug.cgi?id=1805919, and found that it is still broken. I filed https://bugzilla.mozilla.org/show_bug.cgi?id=1807043 for it with some extremely rudimentary debugging.
