Category: IDLE Group: Python 2.3 Status: Open Resolution: None Priority: 5 Submitted By: Mark Poolman (mgpoolman) Assigned to: Nobody/Anonymous (nobody) Summary: idle freezes when run over ssh Initial Comment: Python 2.3.4 (#2, Aug 13 2004, 00:36:58) [GCC 3.3.4 (Debian 1:3.3.4-5ubuntu2)] on linux2 IDLE 1.0.3 When running idle over an ssh link, idle freezes after an unpredictable length of time. Over 3 days the longest it has stayed allive for is ~4hrs, but a few minutes before freezing is the norm. Niether idle nor python are consuming cpu time once frozen. I can find no definete recipie to bring about the freeze, although (I think) there has always been at least one editor window open when it happens. There is no output on stderr, or other diagnostics that I can see. ssh server(ubuntu warty): OpenSSH_3.8.1p1 Debian 1:3.8.1p1-11ubuntu3.1, OpenSSL 0.9.7d 17 Mar 2004 ssh client (RH9): OpenSSH_3.5p1, SSH protocols 1.5/2.0, OpenSSL 0x0090701f /best/* Mark ---------------------------------------------------------------------- >Comment By: Mark Poolman (mgpoolman) Date: 2005-04-19 11:05 Message: Logged In: YES user_id=993923 Haven't been using the machine in question for a while. I can't reproduce the problem on an opteron with equivalent set up. (The machine I reported this on is a celeron). I've atatched a stack trace from gdb, having interrupted with ctrl-C at the gdb prompt when idle froze. ---------------------------------------------------------------------- Comment By: Kurt B.

More precisely, IDLE freezes when updating the "Recent Files" menu if an implicit conversion of unicode to ASCII string occurs. The patch fixes it. Sorry if it is irrelevant. ---------------------------------------------------------------------- Comment By: Kurt B. Kaiser (kbk) Date: 2005-03-04 00:28 Message: Logged In: YES user_id=149084 There have been recent reports on idle-dev regarding IDLE freezing on Debian Sid. Since ubuntu is Debian derived, I assume there may be a relationship. ---------------------------------------------------------------------- Comment By: Mark Poolman (mgpoolman) Date: 2005-02-02 18:50 Message: Logged In: YES user_id=993923 >0.8 doesn't have the problem. Are you sure? Can't be certain as haven't used it for extended periods on that box, but I'll look into it. I've used IDLE daily for about 4 years on various RH and Suse, and never seen a problem until now. > What else is the ubuntu box doing? Is the load heavy? Almost nothing, it's there to evaluate ubuntu as a desktop w/s, and my main activity is getting some in-house python s/w ported to it. gdb results to follow. ---------------------------------------------------------------------- Comment By: Kurt B. Kaiser (kbk) Date: 2005-02-02 17:21 Message: Logged In: YES user_id=149084 To keep things simple, please start IDLE with the -n switch directly on your ubuntu box for the purposes of future investigations on this issue. Can you attach to the frozen IDLE with gdb and then use 'bt' to get a backtrace and find out what was going at at the time of the freeze? If so, is it repeatable? It's occasionally reported that IDLE freezes. I've never seen it myself, running IDLE for many days on OpenBSD, Debian, RH, and Arch Linux, WindowsXP, W2K, and W98, over a period of many years, so it's hard for me to figure out what's going on. But it's peculiar that 0.8 doesn't have the problem. Are you sure? What else is the ubuntu box doing? Is the load heavy? ---------------------------------------------------------------------- Comment By: Mark Poolman (mgpoolman) Date: 2005-02-01 13:35 Message: Logged In: YES user_id=993923 > So if I follow correctly, IDLE -n freezes on your ubuntu box without using ssh tunneling. That is correct. The problem appears exactly the same when run over ssh though, which, I guess rules out any gnome/metacity/X wierdness. > I suspect a hardware problem I' sceptical about that. There's nothing in dmesg or /var/log to suggest it, and absolutely no other problems with the machine in question. >Are you starting IDLE from the command line Yes, but no messages are shown. > How much memory 255MB, IDLE uses about 3.5% of that on startup, grew to 5.7% at time of last crash ---------------------------------------------------------------------- Comment By: Kurt B. Kaiser (kbk) Date: 2005-02-01 02:01 Message: Logged In: YES user_id=149084 Right, there is no subprocess when you use the -n switch. It causes IDLE to run like IDLE 0.8. So if I follow correctly, IDLE -n freezes on your ubuntu box without using ssh tunneling. I suspect a hardware problem with that system. Are you starting IDLE on the ubuntu box from the command line? If so, are there any messages left in the command line window? How much memory does the ubuntu box have? Does 'top' show increasing memory requirement for the IDLE -n process? ---------------------------------------------------------------------- Comment By: Mark Poolman (mgpoolman) Date: 2005-01-31 16:46 Message: Logged In: YES user_id=993923 2 - erm forgive me for sounding stupid, but with the -n switch I see no sub-process, only the Idle process. It still freezes though, and killing it just kills it. ---------------------------------------------------------------------- Comment By: Mark Poolman (mgpoolman) Date: 2005-01-31 16:27 Message: Logged In: YES user_id=993923 1 - OK It's not ssh it's ubuntu. 2 - I'll try this with ububtu. ...And by frozen, I assume ... All Idle windows are unresponsive to screen and kbd events. ---------------------------------------------------------------------- Comment By: Kurt B. Kaiser (kbk) Date: 2005-01-31 06:26 Message: Logged In: YES user_id=149084 Please try two things: 1. Run IDLE directly on the ubuntu machine long enough to assure there is no problem standalone. 2. Run IDLE on the xclient but start it with the -n switch so it runs without the subprocess. When IDLE freezes, walk over to the server and kill the subprocess. It should restart itself. Is the system still frozen? And by frozen, I assume you mean all screen and keyboard events are unresponsive. ---------------------------------------------------------------------- Comment By: Mark Poolman (mgpoolman) Date: 2005-01-30 20:06 Message: Logged In: YES user_id=993923 Yes, I've used Idle on that (although only ~ 1 hour) and not seen the problem there. ---------------------------------------------------------------------- Comment By: Josiah Carlson (josiahcarlson) Date: 2005-01-30 19:43 Message: Logged In: YES user_id=341410 Do you have physical access to the ubuntu warty machine, and if so, does Idle run very well locally on that machine, not X forwarded? ---------------------------------------------------------------------- Comment By: Mark Poolman (mgpoolman) Date: 2005-01-30 17:02 Message: Logged In: YES user_id=993923 Yes, exactly. I'm pretty sure it's not an X/ssh/network problem, everything else works fine (including Idle 0.8).

Do you mean that you have an SSH tunnel to a remote machine, which forwards X-Windows sessions, and when running Idle over this, it locks up? ---------------------------------------------------------------------- Comment By: Mark Poolman (mgpoolman) Date: 2005-01-26 09:15 Message: Logged In: YES user_id=993923 PS - You don't need an editor window open to get the freeze.
