[issue24748] Change of behavior for importlib between 3.4 and 3.5 with DLL loading
Etienne Fortin added the comment: I replaced: import importlib.machinery loader = importlib.machinery.ExtensionFileLoader(name, path) return loader.load_module() With: import importlib.machinery loader = importlib.machinery.ExtensionFileLoader(modname, filename) spec = importlib.machinery.ModuleSpec( name = modname, loader = loader, origin = filename, loader_state = 1234, is_package = False, ) mod = loader.create_module(spec) loader.exec_module(mod) And it now works as advertised. Since load_module() is flagged as Deprecated, I believe no correction is necessary as the preffered way to load a module, with exec_module(), is working. I will do some more tests to be sure it's the case. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24748 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Etienne Fortin added the comment: It is also possible that the root cause is related to Microsoft Windows Update 2999226 and/or 3065987. The behavior was the same between 3.4 and 3.5 on a machine without these updates and is believed to have changed after the install of these updates. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24748 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Etienne Fortin added the comment: No the behavior only changed for 3.5. 3.4 works just fine. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24748 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Etienne Fortin added the comment: I suggest the test should use pywin32. The test script could be only: import pywintypes dir(pywintypes) Testing for an attribute that is defined in the DLL would make it pass or fail. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24748 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Etienne Fortin added the comment: The only dll / pyd files I have are all in pywin32. I don't have a build environment for extensions. Can anyone provide me with a very simple extension DLL with at least one exported attribute? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24748 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Etienne Fortin added the comment: At this point I can't say if it's Windows only or if it affect all platform. I can't even guarantee that it will appear on all Windows platform. On my platform (see following), it doesn't work: Windows 7 64 bits with updates 2999226 and 3065987 installed. I can't confirm the update are related either. I just did a quick analysis and between the time 3.5 was working and wasn't anymore these updates were installed. I will create a quick script to reproduce the behavior. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24748 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Etienne Fortin added the comment: Is it possible that the C runtime introduced with 2999226, which I believe is the universal runtime Microsoft is trying to introduce, modified something that makes importlib break on 3.5??? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue24748 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
