944832 - Collect and report output from Android x86 emulator

Status: RESOLVED FIXED

(Infrastructure & Operations Graveyard :: CIDuty, task)

Description

[Geoff Brown [:gbrown]]

android_emulator_unittest.py launches the emulator with -debug all, but does not collect or report the emulator output. Let's report the emulator output in case there is something useful in there.

Attachment: report emulator output

This works for me on the loaner.

I reduced the logging from "-debug all" to "-debug <some useful tags>" because -all produces tens of thousands of lines of output and most of it looks not useful. (emulator -help-debug-tags gives a list of possible options.)

The change in logging level has a curious effect on test failures. Currently mochitest-gl often crashes the emulator. With this patch, mochitest-gl usually does not crash the emulator...but mochitest-1 and mochitest-2 intermittently crash the emulator. Overall, I think the change has a positive effect.
