e3257cf: Game freezes during initialization

[tomreyn]

While initializing a game on this system (see below) the initialization screen freezes and I need to SSH in (due to full screen) to kill -9 (kill -1 is not enough) the glestadv process. The terminal window where I invoked the process outputs this message:

Code: [Select]

glestadv: main/formats.c:1890: _mesa_format_image_size64: Assertion `depth == 1' failed.

[Yggdrasil]

First of all your mesa is unstable. 7.12 isn't out yet. I doubt that's the problem though.

If you can reproduce this problem, can you try to get a backtrace. Set the breakpoint at raise ('b raise', pending as it is in libc).

[tomreyn]

True, I'm using a mesa development version - which works well with other OpenGL games.

The issue I reported is fully reproducible, I cannot start any game, it will always freeze at the same point. I'll happily do the backtrace but I'll need you to provide verbose instructions on how to set the breakpoint and get the trace.

[Yggdrasil]

Oh, sorry. Make sure you built with debug information enabled (CMAKE_BUILD_TYPE = Debug or RelWithDebInfo). Change into the build directory.

Start the debugger and set the breakpoint:

Code: [Select]

$ gdb ./source/game/glestadv
(gdb) break raise
Say yes to pending. Then run the program:

Code: [Select]

(gdb) run
Make a backtrace when you hit the breakpoint:

Code: [Select]

(gdb) backtrace
Quit debugger:

Code: [Select]

(gdb) quit
Answer with yes to close everything. Please post the whole session.

EDIT: Could you also post the content of ~/.glestadv/gae-crash.txt, if it exists. It should have logged a backtrace from the previous run without debugger.

[tomreyn]

Thanks for the instructions.

EDIT: Could you also post the content of ~/.glestadv/gae-crash.txt, if it exists. It should have logged a backtrace from the previous run without debugger.

This file wasn't written to (after all the game fresszes, too, it doesn't just crash).

Cmake tells me this:

[Yggdrasil]

Sorry for the very late reply. Too busy lately.

Thanks for the backtrace. Sadly, i still can't find the cause of all this... I changed some parts of our error handling on linux, so it should create a log now in ~/.glestadv/gae-crash.txt and a core dump in ~/.glestadv/core. Could you please pull in the latest changes and get it crash again? Then please upload the core dump somewhere, compress it with xz or so.

If no core dump is created automatically, enable it manually with 'ulimit -c unlimited'. After that run GAE again. The core dump is then in your current working directory.

Cmake tells me this:

Code: [Select]

CMake Warning:
  Manually-specified variables were not used by the project:

    GAE_USE_PHYSFS

Is -DGAE_USE_PHYSFS=ON deprecated? I've been told to use this in the past.

This option got removed. physfs is always enabled now.

[tomreyn]

It still freezes and thus doesn't get to the point where a core file would get created (I have to kill -9 it in the end), and I double-checked in both possible locations and it's not there. With your new changes, the game does, however, create the ~/.glestadv/gae-crash.txt file:

For what it's worth (may not be much), 606c86a doesn't allow me to run a game either.

It still freezes during game initialization saying
glestadv: main/formats.c:1890: _mesa_format_image_size64: Assertion `depth == 1' failed.

I'd appreciate further instructions if you need more info.

[tomreyn]

I finally got around to try this on another system, unfortunately the exact same thing happens there: the game freezes, and prints
glestadv: main/formats.c:1890: _mesa_format_image_size64: Assertion `depth == 1' failed.
on the terminal.

gae-crash.txt is also written and contains this:

=======================

 My initial tests were on an Intel 4-Core desktop with 8 GB RAM (much of which was unallocated) and a dedicated ATI video card.
This time I've tested on an Intel 2-Core laptop with 4 GB RAM and integrated Intel GPU.

So these are somewhat different, What they have in common, however, is that they both run Ubuntu 11.10 and that they use both use open source graphics driver stacks based on mesa + gallium for 3D. So, since I assume the game still works for some Linux users (?) it may be a safe bet that in the current state it does not work for some or several. It's now two more months until the next Ubuntu release, we'll see whether this version will make GAE run again.

Again, if you have any suggestions what else to try please don't hold back.

[Yggdrasil]

I still have no clue why this is happening. Mesa 7.12 got released in the meantime as 8.0. I should get it in the next days. Let's see if this changes anything for me.

Btw, do you have libtxc_dxtn installed?

I'm still interested in the core dump. GDB can do that too:
(inside build directory)

Code: [Select]

$ gdb ./source/game/glestadv
(gdb) r
Make it crash. You should get a SIGABRT like before.

Code: [Select]

(gdb) gcore
(gdb) q
compress the core dump, e.g.:

Code: [Select]

$ xz core.<pid>
Please upload and post the hash of revision you tried this on. The whole gdb session would be interesting too.

Wow, pretty good guess. Yes, I had it installed on the ATI system (I have not checked the other system, but my guess is it's installed there, too). And after purging the libtxc_dxtn0 package the game runs fine on this system. So the incomplete texture compression implementation in the open source drivers seems to be the problem. I guess I could have thought of this myself, since (to my knowledge) this package is not installed by default. Now what's lacking is a way for the game to detect this situation and to handle it a little more gracefully.

I'm still interested in the core dump.

This is git revision 5de8487 (5de84873130ed12952197ffeaf86cc8feec4fed1).

I've uploaded the core file and sent you the URL in a private (forum) message.

Quit anyway? (y or n) y

I'm unsure why the memory reads fail here. I should not need to run it as root. My guess is these are protected memory areas used by the video driver and other parts of the kernel, so they are probably not of interest anyways.

Btw, do you have libtxc_dxtn installed?

Wow, pretty good guess. Yes, I had it installed on the ATI system (I have not checked the other system, but my guess is it's installed there, too). And after purging the libtxc_dxtn0 package the game runs fine on this system. So the incomplete texture compression implementation in the open source drivers seems to be the problem. I guess I could have thought of this myself, since (to my knowledge) this package is not installed by default. Now what's lacking is a way for the game to detect this situation and to handle it a little more gracefully.

Mhmm, i use mesa 7.11.2 with libtxc_dxtn 1.0.1 on my laptop with ati r300 driver and it works fine, slow but fine. Maybe the new mesa is really the cause of this. Let's see.

I've uploaded the core file and sent you the URL in a private (forum) message.

Thanks for the core dump. I have a look at it later today.

Something I didn't tell you so far is that I'm using the xorg-edgers PPA, which means that I have more recent versions of all graphics stuff installed than there is in Oneiric (Ubuntu 11.10). Plus I'm using oneiric-proposed and oneiric-backports.

Here's an incomplete (I've edited out repositories which only contain single packages and are irrelevant here) list of the repositories I use:

Sorry, I should have told you about this earlier. Still, it's a rock stable configuration, I'm not running into any trouble with MegaGlest or any other GL games (well Braid is troublesome, but that's more because Icculus doesn't have enough time and doesn't get paid enough to make it work properly, and because he favors proprietary drivers over the open source ones :-/ ).

As an update on this, the texture compression library seems to have been renamed in Ubuntu 12.04 and is now called libtxc-dxtn-s2tc0 (probably the same on Debian Wheezy then) . So, to play GAE, one needs to sudo apt-get purge libtxc-dxtn-s2tc0.
