Jens Reidel added the comment:
Just to show the types are inequal:
Without patch file:
>>> inspect.signature(lambda x: None).parameters
mappingproxy({'x': })
With patch file:
>>> inspect.signature(lambda x: None).parameters
mappingproxy(OrderedDict([('x', )]))

[issue39957] bpo39775 not fixed - inspect.Signature.parameters still dict/mappingproxy
New submission from Jens Reidel : Hi guys, compiling CPython from the master branch will result in a git history with the commit https://github.com/python/cpython/commit/211055176157545ce98e6c02b09d624719e6dd30 included and in Lib/inspect.py, however the return type is still like before and behaviour has not changed. Python 3.9.0a4+ (heads/master:be79373a78, Mar 11 2020, 16:36:27) [GCC 9.2.1 20190827 (Red Hat 9.2.1-1)] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import inspect >>> inspect.signature(lambda x, y: None).parameters == inspect.signature(lambda y, x: None).parameters True >>> I have been able to confirm this on all builds I've done. To get it to do expected behaviour and return False on above code, I need to patch back the commit that changed OrderedDict to dict (https://raw.githubusercontent.com/Gelbpunkt/python-image/master/inspect.patch is the file I am using to patch). I have compiled against the codebase of https://github.com/python/cpython/commit/be79373a78c0d75fc715ab64253c9b757987a848 and believe this is some issue with the Lib/inspect.py code internally if the patch file can fix it. -- components: Library (Lib) messages: 364118 nosy: gelbpunkt priority: normal severity: normal status: open title: bpo39775 not fixed - inspect.Signature.parameters still dict/mappingproxy type: behavior versions: Python 3.9 ___ Python tracker <https://bugs.python.org/issue39957> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
