1878958 - IPC should expose method to determine if message type is sync

Status: RESOLVED FIXED

(Core :: IPC, enhancement)

Description

[Christian Holler (:decoder)]

Currently, we have no way to know if a particular IPC message type is supposed to be sync or not. The IPCFuzzController therefore currently does not create sync messages at all because guessing the sync flag would lead to a high amount of discarded messages.

This can be solved by exposing the sync status through a function similar to the IPC::StringFromIPCMessageType function generated by IPDL.
