bugs in Git tree

[piledriver]

Issue with the latest git pull (about 10 minutes ago) seeing same with tarball under Ubuntu 10.04 or Mandriva 2010.0 or 2010.1, only installed/setup Ubuntu to test Megatunix (fresh install) in case of some Debianism issues, but the problem appears identical.

root@gobook:~# megatunix
The program 'megatunix' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadIDChoice (invalid resource ID chosen for this connection)'.
(Details: serial 1265 error_code 14 request_code 1 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)

This IIRC means it crashed, and that's about it.

Now the weird thing--- It works FINE... occasionally.
... seems to possibly be bombing out on ECU interrogation.
(no issues with TunerStudio/Megatune in windows or TS in Linux)

Your "Ubuntu how-to" works as well under Mandriva as it does under 10.04, with the exception of glade naming IIRC.
(it's just called "glade' under Mandriva and 10.04)

Latest git has several bugs in it that are being worked upon, so errors are to be expected. You'd need to recompile it with debugging enabled and run it under GDB to get a meaningful trace that may help with debugging.
i.e.
./configure --enable-debug ; make clean ; make ; sudo make install
cd src
gdb ./megatunix
gdb> run
when it crashes
type "bt" and send me the result.

For comparison, I installed the Win version, it also had serious issues connecting:
It also crashed once trying. (below is only one of many attempts, this one worked eventually)

Loading Settings from: "C:\Program Files\MegaTuni...........

FWIW, The interrogation under (for example) TS also appears to initially fail,(it doesn't load up like it connected, but it also doesn't error out)... once you load a saved project it immediately communicates and loads up. The loading of an existing project (eliminating the need to autodetect) is not an option with megatunix, might be something to consider.

...Or it might be due to me running 303u...

If it's of any help, this is where it bombs out under Ubuntu or Mandriva.

I set it up with debugging and send you a backtrace ASAP.
(EDIT--bt gives no debug info, it's bombing in an external lib, loading up the debug repos/pkgs and trying again)

Also note--- FWIW the latest GTK runtime (2.16) is apparently missing libgdkglext, the 2.12 version you recommend works (of course).

Stepping through the code in ddd, it's not actually crashing per se...
It appears to be failing to interrogate and then shutting itself down, possibly returning an error.

It actually works fine about 1 in 10 tries, and once loaded has no issues.

Since this is git code, is there another more appropriate thread?

I split off the thread. That sort of behavior, where it fails during interrogation a large part of the time but mtx works stably afterwards indicates a threading issue, where the interrogation routine is calling a GTK+ call when it should not (the interrogation runs sa thread. In almost every gui toolkit only one thread can make GUI calls, so mtx uses tricks to allow other threads to do it (message passing), but its possible to make gui calls from a thread and not have an immediate direct failure, which makes it very difficult to find the bug.

Using the latest checked out using Git on the master branch I have the same start up crash as described previously.
And it also regularly crashes when using the program even if it manages to start up.

Any recommendations of a different branch to check out that does not have this bug?

be helpful and compile it with debugging symbols (./configure --enable-debug ; make clean ; make ; sudo make install )
and run it under GDB and get a trace of the failure.
cd src
gdb ./megatunix
gdb> run

when it crashes, type "bt" to a get a trace, and copy/paste the information here. Please do it MULITPLE times to see if it crashes in the same place or not.

Here are the results of compiling Megatunix with --enable-debug and recording back traces.
The problem described in this thread (X bad window) only happened once but it crashed in various other situations.

The context of the crashes look consistent but I am not very familiar with Gtk.

Hope this helps.

those are pretty good traces.. I'll look into them this evening if possible.

I am running Debian unstable with the nvidia drivers (nvidia-glx 195.36.24-4).

I committed a fix for the logviewer fault. it wasn't just one variable it was lots of them. The limits weren't being properly setup.

As for the hang on startup, the badwindow and the GL crash I'm not sure. 2 of those three could be due to a bug in the nvidia driver or a bug in GtkGLext. The badwindow one is likely a threading issue I'm missing somewhere. As several other users have noted a tendancy to crash in the first 5 seconds, and if it gets past that point usually things are fine, its just during that period when things go awry.

[mahler]

That fixed the rpmdot crash bug, awesome!

I did some more digging on the 3d view crash problem...
It looks like it is a problem when using gdk_gl_get_proc_address("glPolygonOffset");
There is a bug report that looks similar [Debian BUG#337022].
And I was able to compile a small program consisting of just that call and it segfaults every time.
The Debian version is up to date so it looks like the next step would be examining the source of gtkglext.

Code: Select all

// get_proc_address.c
// libgtkglext1-dev
#include <gdk/gdkglquery.h>

int main() {
    GdkGLProc proc = NULL;
    
    proc = gdk_gl_get_proc_address("glPolygonOffset");
}

	gcc -g $(INCLUDE) $(LIB) get_proc_address.c


clean:
	-rm -f a.out

The rest of the bugs are tolerable for now.

I have nvidia, however my system is much older (ubuntu 8.04), running the nvidia driver 169.12+2.6.24.18-28.6 for a GeForce 7600 GS

My guess is that there is either a bug in the nvidia driver itself, or in the GTKglext version you have on your debian unstable system
my version is :

dpkg -l |grep gtkglext
ii libgtkglext1 1.2.0-0ubuntu1 OpenGL Extension to GTK (shared libraries)
ii libgtkglext1-dev 1.2.0-0ubuntu1 OpenGL Extension to GTK (development files)

I think you are right about it being a bug in either GTKglext or the nvidia driver.
The versions I have installed are similar to the ones you have installed.

That did not change much. If anything it seems to crash more. And it still sporadically hangs on startup and crashes when trying to use '3d view'.

Code: Select all

jeri@bishop MegaTunix-work$ megatunix 
The program 'megatunix' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
  (Details: serial 25452 error_code 16 request_code 38 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

I believe i solved the other major crashing problem. There was a VERY BAD bug in megatunix due to my inability to follow instructions properly. MegaTunix wasn't properly handling threads and gui interaction like it was supposed to. I have since fixed this and checked in the changes. Testing by others seems to indicate it has solved the major crashes on startup or within the first few minutes of use.

Please pull, recompile, try and report back.

Those changes definitely made an improvement . Not once did it hang during start up in either on or off line mode.
And I did not get any x-window errors.

I am not sure if this anything to do with your recent changes but it seems like the latency when moving between items
is quite high (several seconds). If I turn off "RT Data" latency is much lower and more normal. But this makes it difficult to edit maps when the current value is not highlighted. Interestingly, if you edit a map (spark, VE) and change the cell value it will take several seconds for the cell to show the change but the gauge at the bottom will show the change immediately.

What speed is your computer, and does it have more than 1 core or not?

Turn down the polling and update rates on the comms tab, which should improve responsiveness.
i.e. INCREASE the delay between reads and/or decrease the FPS rates for the sliders/ttext/dash or 3D display(s)

[piledriver]

git pull... Ahhhh....
____Much____ mo betta, no more crashes, but ditto on the update issues, much slower than before (when it connected before)
MTX was frozen almost solid on the old refresh settings, took a minute or 2 to swicth tabs so I could drop it to 5 fps from the defaults.
(once I figured out it wasn't just hung)

Updates were quite speedy before, now... not so much.
Comm seems much more reliable, getting the right strings in the id fields, always.

PentiumM @ a scorching 1.8 GHz, 2G RAM, in a Gobook3 (with a real live serial port, main selection criteria for the machine)
Mandriva 2010.1. (also works under 2010.0)

Screen is 1024x768, 9250M ATI chip for graphics, so it can do OpenGL in hardware if you don't do more than Q3 or Alien Arena on low settings.
(Hey---CPU, resolution and 12" screen bigger than the disposable Netbooks folks use for MS tuning, and I can drop it on concrete from 4', repeatedly. I tested that spec once unintentionally... While running. No damage other than a paint chip on the concrete and to my shorts.)

Now I just have to look for your instructions how to manually reduce the GTK fonts, it doesn't obey the KDE settings like GTK apps are supposed to...
(everything else GTK that ships with the system does, there must be a missing hook)
