New submission from Jakub Kulik <[email protected]>:
Hi,
with the addition of shared memory into Python 3.8, we now have three tests
failing on Solaris, namely `test_multiprocessing_fork`,
`test_multiprocessing_forkserver` and `test_multiprocessing_spawn`. All of them
fail in the same way:
======================================================================
ERROR: test_shared_memory_cleaned_after_process_termination
(test.test_multiprocessing_fork.WithProcessesTestSharedMemory)
----------------------------------------------------------------------
Traceback (most recent call last):
File ".../Python-3.8.0b2/Lib/test/_test_multiprocessing.py", line 4013, in
test_shared_memory_cleaned_after_process_termination
smm = shared_memory.SharedMemory(name, create=False)
File ".../Python-3.8.0b2/Lib/multiprocessing/shared_memory.py", line 100, in
__init__
self._fd = _posixshmem.shm_open(
OSError: [Errno 22] Invalid argument: '//psm_5c1b5800'
The reason for this, in my opinion, is that the test suite is accessing private
`sm._name` instead of the normalized `sm.name`. Returned value already has one
slash prepended, and another one is prepended SharedMemory init is called,
resulting in double slashes, which is incorrect.
Change to `sm.name` fixes this problem.
