New submission from STINNER Victor <victor.stin...@haypocalc.com>: PyFile_FromFd() never changes the name of new created file object:
$ ./python -c "import sys; print(sys.stdout.buffer.name, sys.stdout.name)" 0 0 Expected result: <stdout> <stdout>. --- Binary mode: - with buffering == 0, the file object is a FileIO. Changing the name can be done with: file._name=new_name - with buffering != 0, the file object is a BufferedXXX() and file.raw is a FileIO. So we have to set: file.raw._name=new_name If text mode, the file object is a TextIOWrapper and file.raw is a BufferedXXX() (buffering=0 is forbidden for text file). So changing the name can be done with: file.raw.raw._name=newname. I'm not sure of the classes/types. Note: PyFile_FromFd() shouldn't use PyErr_Clear() if changing the name fails. ---------- components: None messages: 78419 nosy: haypo severity: normal status: open title: PyFile_FromFd() doesn't set the file name type: behavior versions: Python 3.1 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue4762> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
