This one is weird. After 10 hours running, marionette server suddenly disconnected and client raised a IOError: Broken pipe.  When I tried to start a session, it worked like nothing happened.
From marionette_test.py, we catch IOError but only socket.error, if this sort of behavior is expected, do we need to catch this exception as well?

Comment 4

[Malini Das [:mdas] - Away, not checking bugmail]

Yes, we should catch both socket.error and IOError. Do you mean here: https://mxr.mozilla.org/mozilla-central/source/testing/marionette/client/marionette/marionette_test.py#297 or is there another place we're missing this exception?

I noticed that the logcat that's attached doesn't have any Marionette output. Is this because the logcat was generated long after the test was over, or is there just no output from marionette? If it is the latter, do you see any output if you have a session and using marionette actively?

Comment 5

[Paul Yang [:pyang] (away)]

Yes, #297 should be the right place.
We didn't attach logcat during whole test run.  Will try to add and run again, see if we can gather more information.

Comment 6

[Bobby Chien]

Paul, exceptions are still exist? If not, could we close bug?

Comment 7

[Paul Yang [:pyang] (away)]

Not seeing similar ones.  If we consider latest marionette server lost, I guess this bug can be dupped.

Comment 8

[Paul Yang [:pyang] (away)]

We have a new bug to track for all relative issues.
