[New-bugs-announce] [issue31627] test_mailbox if the hostname is empty

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

On just installed FreeBSD the hostname is empty. This causes a failure of test_mailbox.

======================================================================
FAIL: test_create_tmp (test.test_mailbox.TestMaildir)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/home/serhiy/py/cpython3.7-debug/Lib/test/test_mailbox.py", line 758, in test_create_tmp
    self.assertIsNotNone(match, "Invalid file name: '%s'" % tail)
AssertionError: unexpectedly None : Invalid file name: '1506668827.M125806P21276Q34.'

----------------------------------------------------------------------

Changing the "+" qualifier to the "*" qualifier in the regex pattern fixes the issue.

         pattern = re.compile(r"(?P<time>\d+)\.M(?P<M>\d{1,6})P(?P<P>\d+)"
-                             r"Q(?P<Q>\d+)\.(?P<host>[^:/]+)")
+                             r"Q(?P<Q>\d+)\.(?P<host>[^:/]*)")
