1239288 - Add a test for the startup/shutdown of the JobScheduler

Status: RESOLVED FIXED

(Core :: Graphics, defect)

Description

[Nicolas Silva [:nical]]

A lot of the issues I have encountered while implementing the scheduler are shutdown-related so it's worth having a specific test for that.

Attachment: add a test that just starts up and shuts down the scheduler a few thousand times

Attachment: Don't touch mSection after setting mShutdownEvent

RAII made this a bit too easy to overlook, but once mShutdownEvent is set the queue can get deleted concurrently at any time on the main thread so we have to make sure members like mSection aren't touched past that point.
