836339 - Collect full logcat when running remote tests via sutAgent

Status: RESOLVED DUPLICATE of bug 682129

(Testing :: General, defect)

Description

[Geoff Brown [:gbrown]]

Current logcat support clears the log at the start of a test (logcat -c) and pulls the log at the end of the test. logcat keeps a finite buffer, so long running tests (reftests for example) only report the logcat from the end of the test, frustrating some debugging attempts. 

Running logcat concurrent to the running test would allow us to buffer, collect, and report the log from the entire test run.

I think this is not much of a concern for ad-hoc testing on local devices: adb logcat can be run while testing. The main problem is adding sutAgent support so that additional logcat info is available in tbpl runs.

The increase in log volume is a concern: It may not be feasible to append the entire logcat for a reftest run into the test logs. Even so, collecting it concurrently gives us the flexibility to collect the amount of log data desired, rather than the amount that logcat happens to buffer.
