Oolite Bulletins

Hi,

A week ago or so I saw the anouncement of oolite on freshmeat, what reminded me of the good old times on the commodore. So I downloaded, and installed it.
Good work I have to say, the game has really improved!

I could not resist and made some flights, and noticed at a certain point the screen started to hang for a second at first, what turns out to be a complete hang.
When I look at my system performance, I find oolite is using 90 % of my memory (512 in total) and swapping severely.
The only way out is a SIGKILL. I do not know how to reproduce it, but I have seen it happening after 5 minutes of playing, but sometimes it takes up to an hour.

My system is running Mandriva 2006.

Here is the output of the last game I played:

This is 1.62-2 you're running, not an older release candidate?

After trading and playing with a new commander on my x86 laptop (my AMD64 monster-box is ill ) on the 1.62-2 autopackage install, I also hit this. I'd probably made fifteen planetary trips at the point where it starting swapping and became unresponsive. I took a look at top and it had hit 1.6Gb of memory usage so no surprise my 1Gb laptop was complaining.

I'm guessing this is a nasty memory leak going nuts. As I had to kill it and it left me without a mouse in X windows in 800x600, I wasn't able to check the log. I'll get hold of umouse to recover the mouse after such a crash so I can recover a little more gracefully next time. While I wait for my AMD64 box to be repaired, oolite is probably likely to absorb a fair amount of time as it runs nicely on more limited hardware so I'll report if this crops up again.

Right then.

This problem doesn't occur on the Mac, so... there must be something going on that's different in the GNUstep build to do with releasing objects from memory.

Is there a tool that can track object allocations in GNUstep like ObjectAlloc.app, so we can see what objects are leaking and during which parts of the gameplay?

I'm also puzzled. This problem (for me) went away in 1.61. I've let the game run for several hours and the problem hasn't shown up (with my humble 512MB RAM system). I actively played the game for a good hour straight (on several occasions) with no problems. It used to be the case where this would happen all the time on my system (1.60) but it simply doesn't happen any more. This makes it highly vexatious - if I can't recreate it, I can hardly debug it :/

I think there are plenty of thingies for memory analysis for Linux - just none for Objective-C. However, stuffing something into NSObject's alloc/dealloc to record object creation/deletion might be helpful.

I can confirm that there is a serious memory leak in 1.62. OOlite consumed nearly 1.5 GB of memory on my system after jumping through about three systems and killing two pirates.

I'm running Gentoo. I had previously installed 1.52 and used the oolite-update tool to upgrade to 1.62.

Somehow this thread reminds me to an old bug, from which I thought was fixed in v1.53:
Something out of Control
Are you sure this here is something different?
Not that it would help, I'm just curious...

Actually, what I'm seeing may be something similar. I can usually get it to happen 50% of the time jumping from Diso to Riedquat and engaging pirates on the way into the system. At some point the game starts lagging badly and allocating more and more memory until physical memory is exhausted. This typically only takes 30 seconds or so to allocate all 1GB on this machine once it starts happening. Sometimes it happens when in flight, other times not until I dock.

I've had the FPS/Objs display up, but it doesn't appear to be creating any new objects. Nothing interesting in the console output either. Are there any debug flags I can run?

Well, I'm really frustrated. I've had the game running for 10 hours now with not even the merest hint of a problem. This is a Heisenbug of irritating proportions. There *was* a problem absolutely exactly as described in this thread, but for me, it went away when I merged in Giles's changes to go from 1.60 to 1.61. (The problem originally started occuring for me around the time wormholes were implemented, and went away after a big code merge during the 1.61 time period).

It won't happen this week (I have visitors, so I won't get the time to tinker) but I will rig up some memory reporting tool whereby oolite can dump a list of what objects are allocated on a key press. If you guys can stick around I'll probably look at this next week. :/

Normally I am really lazy with registering into new forums ... i really prefer anonymous reply, not needed to have that for all topics for sure, but it would help in getting more ppl to participate here.

Nevertheless I loved elite, i played first encounter and i look forward for all games bringing those into the new millennia ...


I definetely have this bug, too, on my system. Sometimes i can play for some hours before it arrives, other times i cannot even finish one route before that happens.
I did look into it how this comes, and in my opinion this doesn't seem to be a bug in the oolite code itself, but in the underlying gnustep interface :/

I played around in setting up log messages for all objects who call [super init] after the self initialiation and before the dealloc of these objects.
Funny thing is, now oolite is not even starting anymore but stopping after creating the GL Context and loading the music - it is hanging in the message parsing code of gnustep there. I don't see how i can append any files here in this forum, and the log file is definitely large, i also run the debugging session together with valgrind, a memory leak debugger - which shows some definitely bad areas in gnustep, which may be normal and ok though, i am unsure here.

So I put them onto my router and give links to them:

http://busstation.mine.nu/full_log.oolite.bz2
http://busstation.mine.nu/mydiff_to_svn.bz2

may be the seg fault in my debugging session is caused, because i used NSLog wrong? Some of you obj-c guys could help here - i just start to use obj-c through this game now.

Nevertheless running it inside gdb even crashed the debugger itself, which should not be.

Hope this sheds some light and does not bring too many new questions into this bug ....


By the way, i nearly forgot to describe the system which this was test on:

Pentium-M 1.7ghz, 1 gig ram
base system suse 9.0
gcc-3.3.1-29
gcc-info-3.3.1-29
libgcc-3.3.1-29
gcc-c++-3.3.1-29
gcc-objc-3.3.1-29
gnustep-startup-0.14.0.tar.gz


If something is missing, just tell me[/url]

Despite my bad spelling and the long message before, I forgot some important things:

I use an ATI Radeon Mobility 9600Pro

and
to compile the svn it is nice to have Cocoa/Cocoa.h added to /usr/GNUstep/System/Library/Headers ....

carsten@linux:~/apps/games/oolite/oolite-svn> cat /usr/GNUstep/System/Library/Headers/Cocoa/Cocoa.h
#import <Foundation/Foundation.h>
#import <AppKit/AppKit.h>



This makes compiling the Mac Apps easier on GNUstep ... found it in another forum while trying to get the svn repo to compile ....

Can you try running Oolite-Linux 1.55 and see if you can recreate it? (The old version will be in ftp://ftp.alioth.net/oolite/old). Both 1.55 and 1.62 use the same GNUstep version in the dependency pack - but the thing is, no one ever reported it happening with 1.55 (and there were 4,500 downloads of that version at berlios alone, I reckon there has to be at least 7,000 downloads of 1.55 in the wild).

You may have got an intermediate version where I'd merged on my Mac but not compiled on Linux. Oolite-Linux shouldn't need this file since there is an OOCocoa.h file that does the right thing for the platform you're building on (one of the new files, Geometry.h was for a short while directly trying to include <Cocoa/Cocoa.h>).

If SVN isn't building *without* Cocoa/Cocoa.h, then the SVN repo is broken because it's not supposed to need it. (I suggest when debugging this problem, stick to the tagged 1.62-2 release in the 'tags' directory, the trunk will be a bit of a moving target for a while).

using oolite-1.55 gives no fluid framerate for me (although it is not slow, it is just choppy)


using the gnustep libs from that package together with my binary didn't help either - it looks kind of funny, i should post a screenshot ...



so, no, i can't check with 1.55 if the bug appears, too

i could try running it overnight today though, staying near a station or a witchspace exit should be enough

The 'looking kind of funny' is I think some experimentation that Giles is doing with a new collision detection system. For looking at this problem, I recommend sticking with the code in tags/1.62-2 rather than trunk, as that's what's out in the field. The trunk will be a moving (and possibly unstable in other interesting ways) target because it's being used for development.
