From what I know, we've never observed any similar crash and we trace a lot. Maybe @ddiproietto would have ideas. |
Thanks, no I've never observed a crash like this. Can I ask you to share more?

I've forwarded to ddiproietto. |

hi, @ddiproietto any new message? |
You mentioned that you're using v30.0, which is quite old at this point Can you try with a more recent version? I suspect https://r.android.com/2406614 could be related. Otherwise, with the info we have it's hard to understand what the problem could be. |
many teams in company use this sdk together, i write a simple perfetto write demo with asan, and i will try to review the code. |
i tried this method , still crashed at same point. any article help me to know how |
https://perfetto.dev/docs/concepts/service-model is probably what you are looking for. |
please tell me, is there any diff between i send sigterm and sigint to perfetto process by python? os.kill(perfetto_pid, signal.SIGINT)
os.kill(perfetto_pid, signal.SIGTERM) something i can not understand. |
There is no difference between INT and TERM for Perfetto. The important thing is that you wait for perfetto exiting by polling /prod/pid/status before you try and read the trace file. |
