This class doesn't strictly follow rtc::TaskQueue semantics, which makes it surprising and hard to use correctly. Please use TaskQueueForTest instead. This CL follows usual deprecation process: 1/ Rename. % for i in `git ls-files` ; sed -i "s:SingleThreadedTaskQueueForTesting:DEPRECATED_SingleThreadedTaskQueueForTesting:" $i 2/ Annotate old name for downstream users and accidental new uses.
