Test preferences persist across application restarts.

Using controller.restartApplication currently appears to reset preferences between restarts. I have attached a failing test to demonstrate this.
It's blocking nearly any of our restart tests to work with Mozmill 2. So it should block.

Tested on windows linux and mac - looks like it is already fixed! \o/

It looks like this started working with Firefox 13, but fails for Firefox 10, 11, 12.

Here's the pushlog:
Dave, would you be able to do a hg bisect to identify the real bug?

I suspect the patch from bug 294260, which deals with restarts and resetting user preferences. I won't be able to do a bisect today.
Given that we do not have an issue with it in Mozmill 1.5 we should figure out when it has been regressed in Mozmill or Mozbase.

Git bisect has shown that this has been regressed with the landing of the patch on bug 640435. Not sure why but before this changeset I get:

"message": "'test' should equal 'test'"

Result of git bisect:

This has not been fixed. The attached testcase still fails in Firefox 10, 11, and 12.

working testcase

It seems to work fine when using the Services module. Could be an issue with our preferences implementation. I will have to check that.

Test preferences persist across application restarts.

I was wrong. Missed to test against the esr10 branch. :( My new testcase demonstrates this failure as expected. Lets see what it is.
Attachment #626417 - Attachment is obsolete: true
I have isolated those two test methods into two modules. When I run those tests against an existing profile the same problem occurs. But when I only run test1 the pref is still present in the profile after mozmill has been finished. Running test2 alone also passes. So this is indeed a change in the restart code.

Btw. this also happens with the --restart flag.
This problem doesn't happen if you create a profile manually and make use of it during the Mozmill testrun. That keeps me thinking that something is wrong with mozprofile here.
So the problem with --restart seems to be different. Given that this should run tests in isolation mode we reset the profile:

Given that the preference is gone. Not sure what's the right behavior here would be. Shall we keep the profile and just restart the runner? That would leave everything behind and would fix the problem from above. I would say we should do that. Otherwise there will be no option for us to run our tests successfully in isolation mode.

In case of restartApplication() I would assume we behave similar. But that's something I have to figure out now.
The problem goes away if you call usershutdown() instead of restartApplication() first. After the restart the pref still exists and another restartApplication() will also succeed. So something is broken with restartApplication() when the test is in the first session. I will further investigate tomorrow and hopefully be able to fix it soon. It's blocking my update testrun patch.

Let's investigate the possible work around in comment 15. We might just be able to close this as WFM if that works.
Whiteboard: [mozmill-2.0+] → [mozmill-2.1?][investigate work around comment: 15]
Tested both testcases attached here (that use restartApplication()) with all current branches (nightly, aurora, beta, release and esr17) and we have no failures.
Dave confirmed that we have no interest anymore for older versions, so I think it's save to close it now.

Yeah, got fixed in the Firefox 13.0 timeline which we do not support anymore.
