[issue28801] configparser: before_get() method of class Interpolation has positional 'parser' parameter that is not used.
Richard Prosser added the comment: Ah. Something like self._interpolation.before_get(self, section, option, value, d) could be better written as self._interpolation.before_get(parser=self, ...) - but that would require keyword arguments to be used throughout. I still don't grock the apparent 'get()' signature mis-match however. -- ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28801> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue28801] configparser: before_get() method of class Interpolation has positional 'parser' parameter that is not used.
Richard Prosser added the comment: Thanks for the prompt reply. I still don't fully understand yet but there aren't any errors reported so I presume that it is OK. There is another related matter however: PyCharm (2016.2.3) indicates that a get() method signature does not match that of the Mapping class one ... 557 558class RawConfigParser(MutableMapping): 761 762def get(self, section, option, *, raw=False, vars=None, fallback=_UNSET): There are other similar cases I believe. So I am not sure what to make of that, either. -- hgrepos: +363 ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28801> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue28801] configparser: before_get() method of class Interpolation has positional 'parser' parameter that is not used.
New submission from Richard Prosser: >From https://hg.python.org/cpython/file/3.5/Lib/configparser.py (for example): 358class Interpolation: 359"""Dummy interpolation that passes the value through with no changes.""" 360 361def before_get(self, parser, section, option, value, defaults): 362return value but a typical invocation misses out the 'parser' parameter: 796return self._interpolation.before_get(self, section, option, value, 797 d) As far as I can see, this is not a keyword-only parameter, yet PyCharm seems to treat it as one. So maybe this is some new behaviour that I don't understand yet but there seems to be a fault here, IMO. I am using Python 3.5.2 on Windows 7, after using the 'futurize' tool on some legacy 2.7 code that extended self._interpolate (which no longer exists in 3+). -- hgrepos: 362 messages: 281697 nosy: rprosser priority: normal severity: normal status: open title: configparser: before_get() method of class Interpolation has positional 'parser' parameter that is not used. type: compile error versions: Python 3.5 ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28801> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
