Stage 4: Development
9. Implementation
The Hang Reporter is a new feature that reports transient main thread hangs to Telemetry. It is only useful on Windows builds from the Profiling branch because it relies on having Firefox compiled with frame pointers to unwind call stacks. The Hang Reporter functionality is #ifdef'd out on regular release builds. The expected users of this feature are developers running profiling builds. Some of the functionality is also used by the SPS profiler.
The about:telemetry extension will be updated to make it possible to inspect the hang stacks locally. The about:telemetry extension will send the raw stacks to the Symbolication Server for server-side symbolication (using Socorro symbols) and then display the results within the about:telemetry page.
