1650837 - JSProcessActor filtering doesn't work correctly

Status: RESOLVED FIXED

(Core :: DOM: Content Processes, defect, P2)

Description

[Nika Layzell [:nika] (ni? for response)]

The current JSProcessActor test suite doesn't actually test the remoteTypes filtering, and after adding tests, the filtering doesn't work correctly. This patch is to track fixing these issues.

Attachment: Bug 1650837 - Part 1: Fix broken JSProcessActor remoteType filtering,

Previously this option wasn't correctly copied from the WebIDL configuration
object, meaning that it was always ignored.

Attachment: Bug 1650837 - Part 2: Add an includeParent JSProcessActor config option,

This is similar to JSWindowActor's includeChrome option, and defaults to
'false'. If users want to also instantiate the actor in-process, they can set
this option to 'true'.

Attachment: Bug 1650837 - Part 3: Destroy active actors when they are unregistered,

This is needed specifically for tests, which need to be able to unregister &
re-register the same actor with different configuration options. With
JSWindowActors, we can create new windows after each actor is unregistered, but
we can't do this with in-process JSProcessActors.

Attachment: Bug 1650837 - Part 5: Avoid creating new windows for every JSActor test,

This is no longer necessary, as we now tear down the previously registered
window actors when they're unregistered.

Attachment: Bug 1650837 - Part 6: Hack around SpecialPowers being disabled,

The pref is automatically disabled when disabling unsigned extensions, which can
cause issues. This hacks around that issue in the one place which I noticed
doing that.

Attachment: Bug 1650837 - Part 7: Include message name in error when pending queries are rejected,

This improves the usability of the exceptions produced in this situation.

Comment 8

[Nika Layzell [:nika] (ni? for response)]

Attachment: Bug 1650837 - Part 8: Avoid unnecessary sendQuery for DevToolsFrameParent:packet,

The reply was never used, and due to other changes in this bug, was causing
ignored exceptions to be thrown occasionally when a query was sent immediately
before unregistering the actor.
