1329980 - GPU process crash Telemetry is recorded in the child process

Status: RESOLVED INVALID

(Core :: Graphics, defect)

Description

Comparing crash Telemetry for processes, i see that all except GPU do the instrumentation in the parent:

It seems that recording this in the gpu process couldn't record every abort or crash scenario.
I wonder if that shouldn't be recorded in the parent process.

David, do you know who would know if this is intentional or should be changed?

[David Anderson [:dvander] - inactive, e-mail if emergency]

In the GPU model, GPUChild is in the browser/UI/parent process and GPUParent is in the subprocess. The mismatch is because Child/Parent are a sync/async relationship in IPDL, and to render we need to synchronously wait on the compositor sometimes.

So this should be working as-is.

Ah, i see, thanks.
