New submission from Mark Dickinson <dicki...@gmail.com>:
test_issue5604 from test_imp is currently failing on OS X !0.6 (py3k branch),
with the following output:
======================================================================
ERROR: test_issue5604 (__main__.ImportTests)
----------------------------------------------------------------------
Traceback (most recent call last):
File "Lib/test/test_imp.py", line 121, in test_issue5604
file, filename, info = imp.find_module(temp_mod_name)
ImportError: No module named test_imp_helper_ä
----------------------------------------------------------------------
I think this has something to do with the platform automatically
using NFD normalization for filenames. Here's an interactive session:
Python 3.2a0 (py3k:78936, Mar 13 2010, 19:42:52)
[GCC 4.2.1 (Apple Inc. build 5646) (dot 1)] on darwin

>>> import imp, unicodedata
>>> fname = 'test' + b'\xc3\xa4'.decode('utf-8')
>>> with open(fname+'.py', 'w') as file: file.write('a = 1\n')
...

>>> imp.find_module(fname) # expected this to succeed
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named testä
>>> imp.find_module(unicodedata.normalize('NFD', fname))
(<_io.TextIOWrapper name=4 encoding='utf-8'>, 'testä.py', ('.py', 'U', 1))
In contrast, a simple 'open' doesn't seem to care about normalization:
>>> open(fname+'.py')
<_io.TextIOWrapper name='testä.py' encoding='UTF-8'>
[50305 refs]
>>> open(unicodedata.normalize('NFD', fname)+'.py')
<_io.TextIOWrapper name='testä.py' encoding='UTF-8'>
[50305 refs]
