WanXing Wang	72bd2d7e09	[Core] Support back pressure for actor tasks. (#20894) ... Resubmit the PR https://github.com/ray-project/ray/pull/19936 I've figure out that the test case `//rllib:tests/test_gpus::test_gpus_in_local_mode` failed due to deadlock in local mode. In local mode, if the user code submits another task during the executing of current task, the `CoreWorker::actor_task_mutex_` may cause deadlock. The solution is quite simple, release the lock before executing task in local mode. In the commit 7c2f61c76c: 1. Release the lock in local mode to fix the bug. @scv119 2. `test_local_mode_deadlock` added to cover the case. @rkooo567 3. Left a trivial change in `rllib/tests/test_gpus.py` to make the `RAY_CI_RLLIB_DIRECTLY_AFFECTED ` to take effect.	2021-12-13 23:56:07 -08:00
