This is a reland of commit4cd9c9c666
This will be relanded without changes because we discussed the .proto definition package name clashing problem with the Dart in google3 team, and we have decided that the best solution is to ignore the checked in .proto files in google3 builds. TEST=Recorded traces with the Perfetto file recorder and explored them in Perfetto's trace viewer, CI Original change's description: > Reland "[VM] Begin supporting Perfetto file recorder" > > This is a reland of commit7424295ce9
> > The differences between this reland and the original CL are: now the > Perfetto file recorder does not get built in PRODUCT builds, and it does > not get built unless the SUPPORT_PERFETTO macro is defined. > > TEST=Recorded traces with the Perfetto file recorder and explored them > in Perfetto's trace viewer, CI > > Original change's description: > > [VM] Begin supporting Perfetto file recorder > > > > This CL adds the `TimelineEventPerfettoFileRecorder` class, which is a > > timeline recorder that writes a trace to file in Perfetto's proto > > format. This CL supports the recording of all types of timeline events > > except flow events. Support for flow events will be added in a future > > CL. > > > > TEST=Recorded traces with the Perfetto file recorder and explored them > > in Perfetto's trace viewer, CI > > > > Change-Id: Iaa2051e536589a473c5e15f9de9bb9c251f13d38 > > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/278942 > > Reviewed-by: Ben Konyi <bkonyi@google.com> > > Commit-Queue: Derek Xu <derekx@google.com> > > Change-Id: I8713f704b5fbeed5f1231012bce8a32aaf566ae4 > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/286020 > Reviewed-by: Ben Konyi <bkonyi@google.com> > Commit-Queue: Derek Xu <derekx@google.com> Change-Id: Ia97ef1f0fe73e76c7022623b9ae7e21a4ea73a46 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/295804 Commit-Queue: Derek Xu <derekx@google.com> Reviewed-by: Ben Konyi <bkonyi@google.com>
