1029550 - Generate ANR report when we fail due to timeout

Status: RESOLVED DUPLICATE of bug 1027802

(Testing :: General, defect)

Description

[James Willcox (:snorp) ([e-mail]) (he/him)]

In mochitest/reftest/whatever, we sometimes hang, which manifests as a timeout failure. It would be very useful if we sent the process a SIGQUIT in these instances, which causes an ANR report to be generated. I am not sure about 4.0, but on recent Android versions these contain both native and managed stack traces, so it would be very helpful in finding out what caused the hang.

gbrown just literally filed a bug about this. SIGQUIT is what you want? On desktop we SIGABRT which triggers Breakpad. (Either way should be simple.)

Yeah, SIGQUIT triggers the Android ANR machinery. It sounds like following that with a SIBABRT is not a bad idea either.
