Tim Graham <timogra...@gmail.com> added the comment: It might be worth adding part of the problematic regex to the warning message. For Django's tests, I see an error like "FutureWarning: Possible nested set at position 17 return re.compile(res).match". It took some effort to track down the source.
A partial traceback is: File "/home/tim/code/django/django/core/management/commands/loaddata.py", line 247, in find_fixtures for candidate in glob.iglob(glob.escape(path) + '*'): File "/home/tim/code/cpython/Lib/glob.py", line 72, in _iglob for name in glob_in_dir(dirname, basename, dironly): File "/home/tim/code/cpython/Lib/glob.py", line 83, in _glob1 return fnmatch.filter(names, pattern) File "/home/tim/code/cpython/Lib/fnmatch.py", line 52, in filter match = _compile_pattern(pat) File "/home/tim/code/cpython/Lib/fnmatch.py", line 46, in _compile_pattern return re.compile(res).match File "/home/tim/code/cpython/Lib/re.py", line 240, in compile return _compile(pattern, flags) File "/home/tim/code/cpython/Lib/re.py", line 292, in _compile p = sre_compile.compile(pattern, flags) File "/home/tim/code/cpython/Lib/sre_compile.py", line 764, in compile p = sre_parse.parse(p, flags) File "/home/tim/code/cpython/Lib/sre_parse.py", line 930, in parse p = _parse_sub(source, pattern, flags & SRE_FLAG_VERBOSE, 0) File "/home/tim/code/cpython/Lib/sre_parse.py", line 426, in _parse_sub not nested and not items)) File "/home/tim/code/cpython/Lib/sre_parse.py", line 816, in _parse p = _parse_sub(source, state, sub_verbose, nested + 1) File "/home/tim/code/cpython/Lib/sre_parse.py", line 426, in _parse_sub not nested and not items)) File "/home/tim/code/cpython/Lib/sre_parse.py", line 524, in _parse FutureWarning, stacklevel=nested + 6 FutureWarning: Possible nested set at position 17 As an aside, I'm not sure how to fix the warning in Django. It comes from the test added in https://github.com/django/django/commit/98df288ddaba9787e4a370f12aba51c2b9133142 where a path like 'tests/fixtures/fixtures/fixture_with[special]chars' is run through glob.escape() which creates 'tests/fixtures/fixtures/fixture_with[[]special]chars'. ---------- nosy: +Tim.Graham _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue30349> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
