  "message": "Move ChromeProcessDescriptor to an extension (#2256)\n\nAdds an extension range for Chrome to TrackDescriptor, and a\nChromeTrackDescriptor extension proto in protos/third_party/chromium.\nThis causes protos/third_party/chromium to diverge from Chrome\u0027s\nbase/tracing/protos, due to a dependency cycle between Perfetto and\nChrome. Chrome will need to import the changes to\nprotos/perfetto/trace/track_event and update base/tracing/protos in one\ncommit before the next sync from Chrome -\u003e Perfetto.\n\nAlso adds an ExtensionsWireCompatibility test to make sure that\nconverting an inline field to an extension field like this is safe.\n\nNow that ChromeProcessDescriptor is part of an extension, it\u0027s moved to\na different descriptor file which needs to be included when calling\n`serialize_python_trace` for diff_tests. Every other `serialize_*_trace`\nvariant already takes a list of extension descriptors so this brings\nPython in line with other functions.",
