[New-bugs-announce] [issue25004] test_mmap should catch f.close() failure in LargeMmapTests._make_test_file()

[John Beck]

New submission from John Beck:

When running test_mmap on a partition with < 4GB free, it back-traced:

Traceback (most recent call last):
  File "/usr/lib/python3.4/test/test_mmap.py", line 728, in _make_test_file
    f.flush()
OSError: [Errno 28] No space left on device

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3.4/test/test_mmap.py", line 735, in test_large_offset
    with self._make_test_file(0x14FFFFFFF, b" ") as f:
  File "/usr/lib/python3.4/test/test_mmap.py", line 730, in _make_test_file
    f.close()
OSError: [Errno 28] No space left on device

but by wrapping the f.close() inside another try/except block, its failure was caught and the test was able to complete, resulting in a skip for this sub-test and an OK for the overall test.
