-Subject: [PATCH] Bug 1384062 - Make SystemResourceMonitor.stop more resilient
- to errors. r=ahal,gps
-
-The poll() call in SystemResourceMonitor.stop might fail even though
-there is something to read from the pipe, in some corner cases, and
-python won't let us know about it. In that case, an exception is thrown,
-leaving the SystemResourceMonitor (and its callers) in a weird state. In
-practice, this leads BuildMonitor.__exit__ to recall stop, which then
-fails.
-
-So when poll() throws an exception, we pretend there's still something
-to read, and we try to read anyways. If there is something to read,
-recv() will return it, otherwise, it will throw an exception of its own,
-which we catch, pretending we're done.
-
-Furthermore, when there is nothing to read from the pipe, poll() simply
-returns False, and our loop never sets `done` to True, and we then hit
-an assert, which doesn't have its place here, so we remove it.
-
-Finally, the other end of the pipe might have died at any time, making
-sending over the pipe fail, so we also protect against that.
-
-With all these changes, it feels like the reason to backout bug 1239939
-in bug 1272782 should have been dealt with, and we can drop the timeout
-again.
