Deadlock(?) when saving state while on about:performance


(GeckoView :: General, defect, P2)



(Not tracked)


(Reporter: sebastian, Unassigned)



In the reference browser whenever we save the state of a GeckoSession while we are on "about:performance" this save operation blocks indefinitely.

In the current version of the reference browser this blocks our UI thread. After removing this and only saving on the background thread this unblocked the UI thread - but the save operation still freezes up and never completes.

Reference Browser issue:

This pretty much kills our session saving since all later save requests get cancelled since one is already ongoing.

Dylan thinks the synchronous saveState API in bug 1475648 will fix this about:performance hang.

P2 for now if this hang only affects about:performance.

I think you meant bug 1463878.

Depends on: 1463878
No longer depends on: arm64-baseline-tests
Hardware: Unspecified → All

I think this doesn't only affect about:performance. But this is a reliable way for us to reproduce this.
