Hi, thanks for raising the the issue.

The missing blocked function issue seems like a bug and I can repro it on my side.

The process name cannot be preserved in the systrace format, so that's not something we can fix. That's one of the reasons the Perfetto trace format was invented in the first place!

I'll try to find some time to take a look at the blocked function issue at some point in the next few weeks.

Ok, please fix the missing blocked function as much as you can, thank you

I've just landed a fix in https://android-review.googlesource.com/c/platform/external/perfetto/+/3556923

Note: It turns out this was a bug in traceconv, so any traces you have converted will need to be converted again.

ok, So which release version will have this modified result？

[stevegolton]

I'll be in the next SDK release, which I don't have a timescale for. For now you'll have to build from source if you want to use it.
