1509143 - Consider making IProtocol implement nsISupports

Status: NEW

(Core :: IPC, enhancement, P3)

Description

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

In reality, the majority of our actors are already reference counter, and implemented using hacky workarounds on top of the custom lifecycle system in IPDL. It would make implementing new actors easier & less error prone if we could move this understanding of actor lifetimes into IPDL itself, which would probably involve making IProtocol objects implement nsISupports (for AddRef and Release virtual methods).

Alternatively, we could add AddRef and Release virtual methods directly on IProtocol, but it seems like it'd be cleaner to just use nsISupports for that purpose.
