Category: Build Group: Python 2.3 Status: Open Resolution: None Priority: 5 Submitted By: Datranet (richardjmason) Assigned to: Nobody/Anonymous (nobody) Summary: MemoryError on AIX52 Initial Comment: I found the orginal problem when trying to send large email attachments on AIX 5.2. I tracked the issue down to the fact that a string can only grow to a very restricted size on AIX 5.2. bin2ascii fails at the pint the function tries to join the list togther to form 1 string. I wrote the following test program to prove the issue: a = '' cnt = 0 while cnt < 1024: a = a + 'x' cnt += 1 c = '' cnt = 0 while cnt < 1024: c = c + a cnt += 1 b = '' cnt2 = 0 while 1: b = b + c cnt2 += 1 print cnt2 On AIX 5.2 you get a MemoryError with a cnt2 value of 42. I can run the test program on all other platforms and get a cnt2 value over 150 before stopping to program myself. I have tried the binary python 2.2 from the IBM site and building python 2.3.4 myself using the gcc from the IBM site. Both fail with a cnt2 value of 42. Can anyone please advise on how to get AIX 5.2 to allow single objects to have more memory allocated. ---------------------------------------------------------------------- >Comment By: Neal Norwitz (nnorwitz) Date: 2005-10-02 22:23 Message: Logged In: YES user_id=33168 richardjmason, are you still having this problem? ---------------------------------------------------------------------- Comment By: Michael Hudson (mwh) Date: 2004-08-05 04:59 Message: Logged In: YES user_id=6656 A way this has happened in the past is calling "malloc(0)", which is entitled to return NULL and Python then thinks this is a memory error. This doesn't seeme especially likely here, though. Agree with Martin that you're probably going to need to use a debugger. ---------------------------------------------------------------------- Comment By: Martin v. Löwis (loewis) Date: 2004-08-04 11:09 Message: Logged In: YES user_id=21627 You need to use a debugger to find the cause of the problem. What is the string parameter of the MemoryError? This might give a clue where precisely it is raised. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1002465&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
