Convert Hermes Events to events the Chrome Profiler understands about hermes-profile-transformer HOT 4 CLOSED

I went through the files, and I believe one helpful file is android_events.

• It constructs an Android Tracing Agent (here).
• Methods that collect and preprocess trace data: here and here
  I think this would help us understand how each event is traced on Android.

However, I didn't find where they label the phases of these events. I just found they list the categories of the events, which are not the same as phases (here).
Also we need to research how they generate the stackFrames of events.

I went through how the Chrome Profiles do this and came across the Catapult Project which basically implements the trace-viewer for Chrome. I believe we can find the way to make sense of our code by digging deep through this repository

On some research I found this systrace/profile_chrome/main.py file to be relevant to what we want to achieve. My reasons for believing so are simply based on this line in the code. This leads us to this systrace/profile_chrome/profiler.py file where a CaptureProfile Method has been implemented, now the relevant line in this method is probably the tracing_controller, which leads us to the systrace/systrace/tracing_controller.py file containing tracing code, however such tracing code is also available at other locations, for example: ftrace_events, android_events. From what I understand, the tracing_controller mentioned earlier, aggregates the events generated by these events. For the purposes for this project, I think we should pay particular emphasis on the Android Agent. However, this does require an extremely deep dive into the code. I think we should confirm with @jevakallio if we are on the right path, or if I am mistaken here.

I think the categories are input as args via the command line or something, because they say "--list-categories". Looks like a command line thing, right?

The Hermes Profile can be converted to a format that Lighthouse parser can understand, which can convert the profile into B/E type events.

This finding makes this issue redundant.
