Content
The commit from 2.49 to 2.50 in Modules/mmapmodule.c has made mmap under UNIX leak a file descriptor: - m_obj->fd = fd; + m_obj->fd = dup(fd); The FD given is dup'ed in order to allow ftruncation later, but no close of it is done in dealloc/close. A test case attached, using lsof after some mmaps/unmaps to show leak. Version: Python 2.4.2 (#2, Sep 29 2005, 00:23:59) [GCC 4.0.2 (Debian 4.0.1-9)] on linux2
