New submission from Jason R. Coombs: Today I encountered a bug where I was using a Distutils.Command subclass, which uses getopt for option parsing. The implementation is here: https://bitbucket.org/jaraco/jaraco.packaging/src/2.2/jaraco/packaging/depends.py?at=default
Around line 59, the options are defined, but because the syntax is Python 3 style with unicode literals, under Python 2.7, those get created as unicode objects. When I invoke that Command under Python 2.7, I get this error: Traceback (most recent call last): File "setup.py", line 160, in <module> setup(**setup_params) File "/usr/lib/python2.7/distutils/core.py", line 138, in setup ok = dist.parse_command_line() File "build/bdist.linux-x86_64/egg/setuptools/dist.py", line 250, in parse_command_line File "/usr/lib/python2.7/distutils/dist.py", line 467, in parse_command_line args = self._parse_command_opts(parser, args) File "build/bdist.linux-x86_64/egg/setuptools/dist.py", line 533, in _parse_command_opts File "/usr/lib/python2.7/distutils/dist.py", line 564, in _parse_command_opts (args, opts) = parser.getopt(args[1:]) File "/usr/lib/python2.7/distutils/fancy_getopt.py", line 253, in getopt self._grok_option_table() File "/usr/lib/python2.7/distutils/fancy_getopt.py", line 171, in _grok_option_table "must be a string of length >= 2") % long distutils.errors.DistutilsGetoptError: invalid long option 'requirement=': must be a string of length >= 2 That error is raised because 'requirement=' is a Unicode, but the test in fancy_getopt is isinstance(opt, str). I can work around the issue by wrapping all of the options in str() calls, which leaves them unchanged on Python 3 and downcasts them to strings on Python 2, but that's not pretty. I suggest that fancy_getopt should either include 'unicode' in the isinstance test or (if unicode values really aren't supported), encode unicode values first. ---------- components: Library (Lib) messages: 197020 nosy: jason.coombs priority: low severity: normal status: open title: getopt chokes on unicode option names versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18936> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
