Private function glob.glob1() used in Lib/msilib and Tools/msi to prevent unexpected globbing in parent directory name. ``glob.glob1(dirname, pattern)`` should be replaced by ``glob.glob(os.path.join(fnmatch.escape(dirname), pattern)`` in external code.

I have added some comments on Rietveld.

Note that glob.glob() and glob.glob1() returns different filenames. The first returns full paths and the second returns bare filenames without a directory path. Workarounding this may require more in-depth changes to the code.

Actually this is a low priority issue. It is no so bad to use private functions from other modules inside Python stdlib. But it can be a bad example for a third party code.

Just a reminder that there are comments on Rietveld.

Martin, this patch touches some of your code.  Do you care to take a look at it?

For now there is only one place left that uses glob1(). Here is a patch that inlines glob1() in that place.

The patch for issue25596 removes glob1(), so we should get rid of its usage.

It looks to me that the glob() method of msilib.Directory is broken from the born. It uses the function from the glob module, but the glob module is not imported in this source file.

Even if add missed import, returned value is incorrect in Python 3. In Python 2 glob.glob1() always returned a list, but in in Python 3 it can return an empty list or an iterator. After iterating on it msilib.Directory returns an empty list or exhausted iterator.
