    [tracing] Fix TracingCpuProfiler test for Perfetto · 5ab7510e
    Peter Marshall authored
    Update the TracingCpuProfiler test to work properly with perfetto.
    
    Roll perfetto to get fixes for bugs encountered with starting/stopping
    tracing rapidly, which happens in the test for the tracing profiler.
    
    Add a check that the DataSource::Register call was successful to flush
    out any errors there (although they are fixed by the perfetto roll).
    
    Emit a fake trace event when stopping tracing in order to avoid
    losing the final trace event that the user provided. Remove the ad-hoc
    fake final trace events that the cctests for perfetto added.
    
    Add a test StartAndStopRepeated which flushes out the issues fixed by
    the perfetto roll.
