The test is: do_check_neq(aResponse.profile.threads.samples.length, 0); So this means that despite the profiler running for 200ms, there was no sample. Benoit, any idea?
Component: Developer Tools: Debugger → Gecko Profiler
Product: Firefox → Core
Would increasing the timeout help? Do we expect to get hundreds of samples in 200ms?
(In reply to Panos Astithas [:past] from comment #2) > Would increasing the timeout help? Do we expect to get hundreds of samples > in 200ms? we should be getting around 200. I'm getting 198 on my machine.
My gut feeling for that bug is that the profiler isn't fully started. We spawn a different thread to do the signalling, I wonder if that thread is not up and running by then. We could solve the bug by blocking startProfiler on the first sample firing. Right now you start the profiler and the sampling thread will be up and running at some unknown point in the future. With this change we have the nice property that it's ready when we return from StartProfiler. Also I don't think this test should busy wait either. It should call setTimeout 0 or 5ms and poll the profile for data.
The point of the busy wait was to be sure we can identify something in the profile samples, and check that the right info is available in the frames data.
Ohh the test is actually checking the results is in this frame instead of just checking that we have random samples. That's lovely.
Comment 20 to comment 28 are a different failure mode and different platform (and appear to have come across in the latest fx-team merge), so I've broken them out to bug 847314. Marking this bug as WFM for now, since whilst it's likely to be reopened in another few weeks, at least it will reduce the chance of mis-starring until bug 847314 is resolved.
