[issue45464] TypeError when inheriting from both OSError and AttributeError
New submission from Marek Marczykowski-Górecki : In Python 3.10 it is no longer possible to create an exception type that inherits from both OSError and AttributeError. This has worked in Python 3.9. I don't see anything in changelog/release notes that would suggest it being intentional.

[issue39744] asyncio.subprocess's communicate(None) does not close stdin
New submission from Marek Marczykowski-Górecki : Standard subprocess's communicate() called with None input (or no argument at all closes process stdin. The asyncio variant does not. This leads to issue with various processes that wait for EOF on stdin before terminating.

[issue16472] Distutils+mingw links agains msvcr90, while python27.dll is linked agains msvcrt
Marek Marczykowski-Górecki added the comment: I can confirm that when a module is linked against msvcr90, it crashes with invalid access to memory. When removed that library from the linker options (that is - no explicit msvcr, in any version) - module worked perfectly. Note that comment on http://hg.python.org/cpython/file/6e1dd1ce95b8/Lib/distutils/cygwinccompiler.py#l333 (Minge32CComiler class) already says no additional libraries needed, but 3 lines later it sets dll_libraries to msvcr90 (via get_msvcr). So just removing lines 336:338 works great. Patch attached. Any chances to get this fixed in the next python 2.7.x release? My system is Windows 7 64bit, Python 2.7.5 64bit (from official msi installer) -- keywords: +patch nosy: +marmarek Added file: http://bugs.python.org/file31094/python-distutils-mingw32.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16472 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
