Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Python Library Group: Python 2.4 Status: Open Resolution: None Priority: 5 Submitted By: Keith Dart (kdart) Assigned to: Nobody/Anonymous (nobody) Summary: The mmap module does unnecessary dup() Initial Comment: The following no longer works in Python 2.4: _buf = mmap.mmap(-1, 8192, flags=mmap.MAP_PRIVATE|mmap.MAP_ANONYMOUS, prot=mmap.PROT_READ|mmap.PROT_WRITE ) This is because the fd value of -1 raises an exception because it is being dup-ed inside the mmap module. But the fd is ignored in anonymous mmaps and does not need to be dup-ed. This worked in older Python (2.3). Is the dup() call really necessary? My current workaround is to open /dev/null. But this causes "invisible" consumption of file descriptors for the process. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1424041&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
