Well... testing distutils2 on Windows has been quite an adventure. When
I ran the test suite before applying the patch, I got a bunch of failures
on all of the Python versions I tested (except the ones that had issues
preventing me from running the tests at all). Only one of the failures
appears to be due to the current issue.
A summary of the problems, broken down by Python version:
[python3 branch]
- 3.3/3.2: Two failures:
 * One in test_command_build_ext..test_finalize_options where the
 library search path erroneously includes some additional directories
 under the Python installation directory. This failure is not fixed
 by the patch; it continues to fail after the patch is applied.
 * One in test_manifest that looks like this:
 FAIL: test_process_template (distutils2.tests.test_manifest.ManifestTestCase)
 ----------------------------------------------------------------------
 Traceback (most recent call last):
 File "C:\Users\Nadeem\Code\distutils2\distutils2\tests\test_manifest.py", line 215, in test_process_template
 self.assertEqual(manifest.files, ['d/b.py', 'd/d/e.py'])
 AssertionError: Lists differ: [] != ['d/b.py', 'd/d/e.py']
 This one is clearly caused by the whole directory separator regex
 snafu we're trying to fix. Applying the patch fixes it, and doesn't
 introduce any new failures.
- 3.1: Same as above, plus a failure in test_util:
 FAIL: test_generate_setup_py (distutils2.tests.test_util.UtilTestCase)
 ----------------------------------------------------------------------
 Traceback (most recent call last):
 File "C:\Users\Nadeem\Code\distutils2\distutils2\tests\test_util.py", line 557, in test_generate_setup_py
 self.assertEqual(out, b'SPAM\n')
 AssertionError: b'SPAM\r\n' != b'SPAM\n'
 Like the test_finalize_options failure, this isn't fixed by the patch.
[default branch]
- 2.7: Before the tests start running, runtests.py crashes with an
 ImportError complaining that it can't find the winreg module.
 AFAIK the registry-handling module in the stdlib is called _winreg
 in 2.x, and was only renamed to winreg in 3.x.
- 2.6: Same as 2.7.
- 2.5: Twenty (20) failures, including the three I get on 3.1, some
 miscellaneous stuff that looks registry-related, and around a
 dozen errors complaining about non-ASCII characters in
 bdist_msi.py's copyright notice. As above, your patch fixes
 the one failure in test_manifest, but none of the others.
- 2.4: Can't run the tests; needs Visual C++ 2003, which (AFAICT) isn't
 freely available.
TL;DR summary: The patch itself looks good, but D2 and Windows currently
don't get along at all.
I'd like to file a separate bug for the unrelated failures - do I do that
here, or does distutils2 have a separate bugtracker/mailing list?
