1533018 - Shutdown profiles don't have correct metadata information

Status: NEW

(Core :: Gecko Profiler, enhancement, P2)

Description

[Florian Quèze [:florian]]

https://perfht.ml/2EDLDM5 is an example of shutdown profile.

https://perfht.ml/2EDFQWX is another profile (a startup profile in this case) capture on the same machine.

I understand that some information like the list of installed add-ons might not be available anymore during shutdown (although we could cache it earlier if we really wanted to include it), but basic things like the platform and Firefox version/build id should be included.

I think the solution will be something similar to bug 1527564, i.e., (as you hinted) we need to record this information in advance, not just when serializing profiles at shutdown time, when this information may not be available anymore.
