Category: Python Library Group: Python 2.4 >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Peter Vetere (pav3901) >Assigned to: Peter à strand (astrand) Summary: If MAXFD too high, popen2/subprocess produce MemoryErrors Initial Comment: Both the subprocess and the popen2 modules use the range(...) function to iterate over and close inherited file descriptors when a subprocess is spawned. In the OS environment, it possible (using ulimit -n) to set SC_OPEN_MAX (and thus MAXFD in these modules) to a very high value. This can exhaust the limitations of the range() function, producing a MemoryError. The better thing to do would be to use xrange() instead. In particular, this bug occurs in subprocess._close_fds() and popen2._run_child(). ---------------------------------------------------------------------- >Comment By: Peter à strand (astrand) Date: 2006-06-22 22:32 Message: Logged In: YES user_id=344921 Patch 1506760 has been applied. ---------------------------------------------------------------------- Comment By: Peter Vetere (pav3901) Date: 2006-06-15 21:31 Message: Logged In: YES user_id=652852 I've submitted a patch against release24-maint for this bug: 1506760 ---------------------------------------------------------------------- Comment By: Peter Vetere (pav3901) Date: 2006-06-15 18:15 Message: Logged In: YES user_id=652852 I've submitted a patch against release24-maint for this bug: 1506760 ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1506758&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
