[issue4762] PyFile_FromFd() doesn't set the file name
STINNER Victor victor.stin...@haypocalc.com added the comment:
In py3k, standard streams' names are now correct (since the io-c
merge):
Python 3.1a1+ (py3k:70589M, Mar 25 2009, 01:01:13)
import sys
sys.stdin.name, sys.stdout.name, sys.stderr.name
('stdin', 'stdout', 'stderr')
The last problem occurs with imp.find_module(). But imp.find_module()
also returns a filename argument, so I don't think that the issue
really matters. Let's close it ;-)

[issue4762] PyFile_FromFd() doesn't set the file name
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
[issue4762] PyFile_FromFd() doesn't set the file name
STINNER Victor victor.stin...@haypocalc.com added the comment: In my last patch to fix the issue #4705, I replaced PyFile_FromFd() by custom code which set correctly the file name. PyFile_FromFd() is also used in: - _Py_DisplaySourceLine(): name is not used, only PyFile_GetLine(file) - call_find_module() (imp.find_module()): return the file object with the wrong name Example with imp: file, filename, extra = imp.find_module(os) file io.TextIOWrapper object at 0xb7b6ea6c file.name 4 filename '/home/SHARE/SVN/py3k/Lib/os.py' ___ 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
