command timed out: 1200 seconds without output, attempting to kill
process killed by signal 9
program finished with exit code -1
This is fallout from bug 597064.
Blocks: 597064
I suppose the only way proc can be null is if launchProcess didn't actually complete successfully? I guess we should cancel the timer in the finally block.
So the remote/b2g harnesses don't actually return a process from launchProcess:

Signature has morphed; updating summary (this will also reduce false positives).
Summary: Intermittent B2G xpcshell command timed out: 1200 seconds without output, attempting to kill from "AttributeError: 'NoneType' object has no attribute 'pid'" → Intermittent B2G xpcshell "AttributeError: 'NoneType' object has no attribute 'pid'"

Hoping this might be fixed (or at least the way paved for it), by the Android equivalent, bug 875814.

Summary: Intermittent B2G xpcshell "AttributeError: 'NoneType' object has no attribute 'pid'" → Intermittent B2G/Android xpcshell "AttributeError: 'NoneType' object has no attribute 'pid'"
I'm not sure if it's the same issue or not, but debug b2g xpcshell just went live and they are hitting a constant failure with the same signature in test_ril_worker_sms_gsmpduhelper.js:
https://tbpl.mozilla.org/php/getParsedLog.php?id=31840617&tree=Pine

Note that they were running fine on Tuesday, the regression is somewhere in:
https://hg.mozilla.org/projects/pine/pushloghtml?startID=84&endID=85

I filed a new bug for the debug b2g xpcshell issue because it isn't intermittent. Could still share the same root cause though.
B2G is gone.
