bactrace for tracked using 10/29/07 git wine

somewhere between release 0.9.46 and 0.9.47 of wine i started having
problems with applications that use opengl. using git-bisect i found
that commit 00633e37bcc8da1032f34ea2d87814739de07db4 (winex11: Use an
offscreen redirected window for child OpenGL rendering.) was the first
bad commit. this happens both on my thinkpad with an radeon r250 card using the
open source drivers and on my desktop using an nvdia card with the proprietary
nvidia drivers.

in particular i am trying to run tracked part of racer 0.5.0 final
(http://racer.nl/dl_win32.htm).

i am attaching the back traces for the various cases

I'm unable to reproduce the crash on my desktop with an Nvidia card and Nvidia
proprietary drivers.  What steps do you take to produce the crash?

Adjusting keywords and cc'ing author of patch.

run tracked, press i (import track) and when it prompts for filter expression
type * (or just hit return). if you said * the program will start drawing the
track objects and then crash with one of those backtraces.

Thanks.  Confirming, I can reproduce it too.

I've followed those steps, and I can't reproduce it here. Tried with both
virtual desktop, and managed. nVidia Geforce 8600 with the latest drivers.

It appears, though, that it's trying to call glFlush when there isn't a valid
context. Both traces have..

** Warning: Pixel format (1) is of unknown type; may be slow (software
rendering)!

Can you paste a +wgl,+opengl log?

I'm using Xorg 7.2. I notice in the log you're using 16-bit color in X, and the
selected pixel format is marked as slow. Can you try 24-bit color?

The log seems to indicate it's setting a NULL context right before calling
glFlush, which causes the crash (you can't make GL calls like that without a
context set). I can't see anything in the log which would cause the program to
do that, nor can I see why that commit would change it.

The only thing I can think of is that the driver's more forgiving when there
isn't a context, but that doesn't explain why it works for me.

i run 24-bit color on my desktop and i get the same crash. i have this
suspicion the crash is related to using xorg 7.3 (i first noticed it happening
around the time i upgraded xorg to 7.3). i'll try to find a computer still
running xorg 7.2 and see if i can reproduce the crash.

Hello,

Try to download native linux version of game from
http://www.racer.nl/download.htm and see if same problems persist.
Both versions crash in my notebook with ATI IGP 320m video card.

It may be driver issue as well.

Cheers,
Arunas

i don't think the linux version of tracked ever worked. this is why i always
ran it under wine. on the other hand the windows version of tracked used to
work under wine but not any more.

there goes my theory. i ran tracked under the latest git wine on a computer
with xorg 7.2 and it still crashed. i saved the log if anybody is interested
but as far as i can tell it still crashes the same way. this is bizarre.

with this patch applied:

--- a/dlls/winex11.drv/opengl.c
+++ b/dlls/winex11.drv/opengl.c
@@ -2053,7 +2053,8 @@ static void WINAPI X11DRV_wglFlush(void)
     sync_context(ctx);
     pglFlush();
     wine_tsx11_unlock();
-    ExtEscape(ctx->hdc, X11DRV_ESCAPE, sizeof(code), (LPSTR)&code, 0, NULL );
+    if (ctx)
+      ExtEscape(ctx->hdc, X11DRV_ESCAPE, sizeof(code), (LPSTR)&code, 0, NULL
);
 }

tracked runs fine. you seem to believe the context should be set but in this
case it's not.

The program seems to work fine on my Nvidia card. Note a lot has changed in GL
over the last couple of months. Second if the child window patch caused issues,
most of those are not really fixable (without using hacks). The problem is that
not all drivers support the functionality we need properly yet.
