Some hacky UI for sending plugin-process crash reports

Until the real UI for plugin crash reports is done, I want to get some really hacky UI up, so that we can enable them in mozilla-central. This will unlocalized and will pop up a non-modal dialog for the user to hit send/cancel.
This is hacky temporary UI for submitting plugin-process crashes.

This is just leftover cruft from cjones' patch queue, right?

You want to make these dump() or something, or remove them.

You need to removeEventListener here (you removed the .onload = null), otherwise this handler will fire again after the form submits and the response loads.

Can we put a TODO comment at the top of this file listing the bug that's going to replace it with a better solution?

This really feels like it ought to be in nsExceptionHandler.cpp where we do this for the chrome process, but I guess we can fix that later... Ideally we'd be able to just share a hashtable of values that are common to both types of processes, and perhaps have a separate one for the chrome-only bits, and then separate per-process info for the child bits.

Data we're not submitting here:
1) the stuff from bug 535829--we should at least hardcode ProcessType=plugin, file a followup for the rest
2) time since last crash--we probably want "time since last crash of this particular plugin", which will require some extra work, can be a followup
3) StartupTime - we want the startup time of the plugin process, lump this in with the followup from #2
3) InstallTime - we can just take the value that the chrome process uses, but it's only available in the C++. Should get filed somewhere

We should also file a followup to find out if we can associate a URL with the plugin process for when we crash. I'm not sure how this would work exactly, but we know the document each plugin instance is loaded from, so perhaps if we crash while doing something from that document we can send the URL? Reproducing crashes without any URLs is going to get hard.

Can you file a followup on making crashes.js more readily usable from elsewhere? We're going to want to share that code when we get the right UI hooked up here.

It would probably be good to have some sort of indicator that the crash submitted successfully or not. crashes.js is not very good about that, I know.

>diff --git a/toolkit/crashreporter/content/oopcrashdialog.xul b/toolkit/crashreporter/content/oopcrashdialog.xul

It would probably be good to stick a throbber or something in this dialog, even if it is placeholder UI.

The changes in this file look unintentional or unnecessary.

I'd call this "dumpFile" instead of "f".

Same here, "mDumpFile".

This should be fixed by cjones' latest patch, I think.

Presumably this is an unnecessary change (and fixed by the patches in your other bug).

r+ with those changes as long as we make it clear that the XUL+JS here is not going to ship in anything but an alpha, and the bug about the final UI is blocking.

Followups are filed for everything except "make crashes.js more usable", since I think that's subsumed into bug 525849.
