1654379 - Allow filtering the IPC log by multiple toplevel protocol names

Status: RESOLVED FIXED

(Core :: IPC, enhancement)

Description

[Jon Bauman [:jbauman:]]

In the context of analyzing GMP code, it's useful to log a variety of IPC messages for protocols such as PGMPContentChild and PGMPContentParent while excluding much noisier protocols such as PContentChild and PContentParent. To facilitate this, we can extend the implementation in mozilla::ipc::LoggingEnabledFor which currently reads the MOZ_IPC_MESSAGE_LOG environment variable and either logs all protocol messages when it is set to 1 or only the specific protocol name matching its value.

Similar to the behavior of MOZ_LOG, multiple protocol names should be allowed in the value of MOZ_IPC_MESSAGE_LOG delimited by commas (,) or spaces ( ).
