4 tests are still failing and require more investigation (they can be fixed in a separated PR): test_multiprocessing_fork.test_processes
test_wait_result
test_multiprocessing_spawn.test_processes
test_wait_result
test_multiprocessing_fork.test_misc
test_resource_tracker_sigterm
test_multiprocessing_spawn.test_misc
test_resource_tracker_sigterm
The forkserver start method requires multiprocessing.reduction.HAVE_SEND_HANDLE which is False on Cygwin. Maybe we can support forkserver if the _winapi extension becomes available on Cygwin. |
