[issue28935] distutils use ConfigParser in Python 3.x and fails to parse setup.cfg with percent sign
New submission from Axel Haustant: Because of the Python 3.2 configparser renaming/refactoring, string interpolation has been enabled into distutils config parsing and so fails to read any setup.cfg with percent signs (try to perform string interpolation and fails). To reproduce: create a project with a percent sign anywhere in the setup.cfg file and execute python setup.py egg_info. It will pass on Python 2.x and fails on Python 3.x. The attached patch suimply disable string interpolation in distutils config parsing. That would be awesome to have this applied on any 3.x version (because project using tox to test against different Python versions also fails with the same issue Python 3.x and PyPI 3.x) -- components: Distutils files: disable-distutils-string-interpolation.patch keywords: patch messages: 282865 nosy: Axel Haustant, dstufft, eric.araujo priority: normal severity: normal status: open title: distutils use ConfigParser in Python 3.x and fails to parse setup.cfg with percent sign type: crash versions: Python 3.3, Python 3.4, Python 3.5, Python 3.6, Python 3.7 Added file: http://bugs.python.org/file45839/disable-distutils-string-interpolation.patch ___ Python tracker <http://bugs.python.org/issue28935> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue28935] distutils use ConfigParser in Python 3.x and fails to parse setup.cfg with percent sign
Axel Haustant added the comment: You're welcome. I understand the backward compatibility point. But I think that the current state is breaking existing code as it's not documented anywhere and it's a side-effect of another change, not something intentionnal. (this is why I submitted this issue because I'm developing a tool which use the setup.cfg file to store data and it is broken in Python 3. I saw a lot of bug reports on different tools with the same issue (ex: nosetest configuration) I cannot use %% for many reason: - it will not work with Python 2.x (problematic for 2/3 cross compatibility) - it needs every tools to know that in Python 3, they have to change their parser Right now, I'm supporting configuration into an external file for Python 3.x Thanks for your response ! I hope that it can be integrated into future releases (noted the point on 3.3/3.4). -- ___ Python tracker <http://bugs.python.org/issue28935> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue28935] distutils use ConfigParser in Python 3.x and fails to parse setup.cfg with percent sign
Axel Haustant added the comment: No it's not. Same problem but on a different part: the two cited issues are about the .pypirc file not the setup.cfg. The parsing does not occurs at the same place and the fix does not works for setup.cfg (I tried before submitting this issue). In this specific case, setuptools calls distutils to parse the file so the fix has to be in distutils not setuptools (whereas for .pypirc, this is setuptools which is parsing the file) -- ___ Python tracker <http://bugs.python.org/issue28935> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Axel Haustant added the comment: Sorry, it is effectively a duplicate of the second one. But I submitted a patch which is not present in the other. What should I do ?

[issue20754] Distribution.parse_config_files uses interpolation since Python 3
Axel Haustant added the comment: I just attached the patch submitted on issue28935. The fix is to simply give interpolation=None as ConfigParser parameter (as documented in the official Python 3.x ConfigParser documentation) -- keywords: +patch nosy: +noirbizarre Added file: http://bugs.python.org/file45859/disable-distutils-string-interpolation.patch ___ Python tracker <http://bugs.python.org/issue20754> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
