[New-bugs-announce] [issue23939] test_get_platform_osx failure on Python 3.5.0a0 osx 10.6

[Alex Lord]

New submission from Alex Lord:

On a fresh clone of cpython 3.5.0a0 if you run

$ ./configure --with-pydebug && make -j2
$ ./python.exe -m test.test__osx_support -j3

on osx 10.10.2 (14C109) these two test failures are reported.

    ======================================================================
    FAIL: test_get_platform_osx (__main__.Test_OSXSupport)
    ----------------------------------------------------------------------
    Traceback (most recent call last):
      File "/Users/alexlord/mercurial/cpython/Lib/test/test__osx_support.py", line 272, in test_get_platform_osx

    AssertionError: Tuples differ: ('macosx', '10.6', 'fat') != ('macosx', '10.6', ' ')

    First differing element 2:
    fat


    - ('macosx', '10.6', 'fat')
    ?                     ^^^

    + ('macosx', '10.6', ' ')
    ?                     ^

    Ran 14 tests in 0.354s


Doing a little more digging I found that this if statement is the one failing.

    if ((macrelease + '.') >= '10.4.' and$
                 '-arch' in cflags.strip()):

Specifically this line 

    (macrelease + '.') >= '10.4'

I used distutils.version.StrictVersion to solve this comparison error.

which is failing because

'10.10' >= '10.4' # This fails because the character 4 is greater than 1.
