Pymol stopped working

[mtiberti (Matteo Tiberti)]

Hello, I'm trying to use PyMOL 1.6.0 on Mac OSX Mavericks, installed through MacPorts, but the same happens with pymol 1.7.1 as well (see ticket #42860). Up to a couple of days ago everything was working perfectly fine. At a certain point I have probably upgraded the installed base (selfupdate + upgrade outdated), and now when I run pymol I get an error (log file attached) and then PyMOL crashes.

I have then tried the following:

• reinstalled PyMOL 1.6.0
• removed PyMOL 1.6.0 and installed 1.7.1
• updated the XQuartz X server to the latest version
• reinstalled the XQuartz X server to an older version
• wiped MacPorts clean and reinstalled PyMOL and its prerequisites from scratch
• installed the gfxCardStatus program and tried both using the integrated gpu and the discrete one
• searched on the internet (of course :) )

I have then asked for assistance in the PyMOL mailing list, and Thomas Holder, a PyMOL developer from Schrodinger, confirmed that he was experiencing the same. It looks like the issue only happens when PyMOL is built in the macports environment, and it's not related to any recent changes to PyMOL. This means that most likely something in macports got broken in the meanwhile.

Thanks for your attention

crash log

[howarthjw@…]

I would suspect that the MacPorts glew package is the obvious candidate for the offender as the errors are related to shaders which is part of glew and the package has been changed several times in the last two weeks. Can you try reverting back through the earlier revisions glew to confirm which release and revision was last work for you? I don't see any problems with the pymol package that I maintain on fink against the fink 1.10.0 glew so the breakage is specific to the MacPorts build of glew. On fink, we are building glew with clang on 10.6 and later (and with gcc-4.2 on 10.5 and earlier). The build is done as…

make GLEW_DEST=%p GLEW_APPLE_GLX=1 CC=$CC LD=$CC

without any additional patches and the resulting package works fine with fink pymol 1.7.1.1.

[howarth.at.macports@…]

I really doubt this is breakage in pymol itself but some other MacPorts package is at fault.

[howarth.at.macports@…]

Is there a way to ask port to install a particular previous archived version and revision of some package from binary archives? I really don't want to have to do a regression hunt through the supporting packages using manual builds.

[howarth.at.macports@…]

Actually, the recent update of the mesa package from version 7.2 to 8.0.5 seems like the most likely candidate. Few programs exercise the GL/GLX support as much as pymol.

[jeremyhu (Jeremy Huddleston Sequoia)]

I assume you mean from 8.0.4 to 8.0.5 ... It hasn't been at 7.2 since around 2009 ...

[jeremyhu (Jeremy Huddleston Sequoia)]

Along with that abort, a message should be printed to stderr. What is the message?

Thanks for your help! Actually pymol installs on MacPorts 2.2.1 which I am using right now (or at least it did yesterday). I have tried installing glew revision 114325 (6 months ago) but nothing changed. I'll try with the mesa package then.

[mtiberti (Matteo Tiberti)]

might be related to #43810

[jeremyhu (Jeremy Huddleston Sequoia)]

I suspect that maybe there's an issue with the 0013-darwin-Fix-test-for-kCGLPFAOpenGLProfile-support-at-.patch ... I wonder if you're getting an error other than kCGLBadAttribute for some reason.

[mtiberti (Matteo Tiberti)]

I can confirm that it works with mesa @8.0.4+py27. However, the command window doesn't show up, but I think it's unrelated

EDIT: installed tcl +threads-corefoundation as in #37062 but it still doesn't work as expected

[howarth.at.macports@…]

I get…

error: invalid pixel format attribute Abort

in the command line when I execute pymol under the current mesa.

[mtiberti (Matteo Tiberti)]

one moment... I will just upgrade outdated and see if I get it as well. I'm on 2.2.1 right now

[howarth.at.macports@…]

FYI, the top command window can take several minutes to open on the first launch. I've never gotten an explanation for that from upstream but assume that it is related to the code probing the video card. As long as you don't logout, the next time pymol is executed the top window opens immediately. Weird bug.

Solved it by installing tk -quartz. I can confirm everything works with mesa@8.0.4+py27

replacement setup_py.diff for pymol 1.7.1.1

[howarth.at.macports@…]

replacement pymol-clang.diff for pymol 1.7.1.1

[howarth.at.macports@…]

You can also use the replacement setup_py.diff and pymol-clang.diff with the Portfile.diff to update pymol to the latest stable release of 1.7.1.1. None of the more recent svn commits are related to display graphics. This is the same version that we are using in fink without issues.

[howarth.at.macports@…]

Same error…

error: invalid pixel format attribute Abort

occurs under pymol-1.7.1.1.

[jeremyhu (Jeremy Huddleston Sequoia)]

Thanks, FWIW, r120370 has better error reporting in the crash log.

error: invalid pixel format attribute Abort

That indicates that you're getting kCGLBadAttribute. I suspect the kCGLBadAttribute is because kCGLPFAOpenGLProfile is still in the list for some reason.

Someone who is reproducing this will need to provide more information or an update to 0013-darwin-Fix-test-for-kCGLPFAOpenGLProfile-support-at-.patch to address the issue.

I suggest you start by figuring out what error is when we test for the kCGLPFAOpenGLProfile support here:

   /* Request an OpenGL 3.2 profile if one is available and supported */
   attr[numattr++] = kCGLPFAOpenGLProfile;
   attr[numattr++] = kCGLOGLPVersion_3_2_Core;

   /* Test for kCGLPFAOpenGLProfile support at runtime and roll it out if not supported */
   attr[numattr] = 0;
   error = apple_cgl.choose_pixel_format(attr, pfobj, &vsref);
   apple_cgl.destroy_pixel_format(pfobj);
   if (error == kCGLBadAttribute)
      numattr -= 2;

[jeremyhu (Jeremy Huddleston Sequoia)]

Also, I assume everyone seeing this issue is on Snow Leopard.

[jeremyhu (Jeremy Huddleston Sequoia)]

Try running this and tell me what it prints:

$ clang testgl.c -framework OpenGL -o testgl && ./testgl

Where testgl.c is:

#include <stdio.h>
#include <OpenGL/OpenGL.h>

#ifndef kCGLPFAOpenGLProfile
#define kCGLPFAOpenGLProfile 99
#endif

#ifndef kCGLOGLPVersion_3_2_Core
#define kCGLOGLPVersion_3_2_Core 0x3200
#endif

int main() {
    CGLPixelFormatAttribute attr[3];
    CGLPixelFormatObj pfobj;
    GLint vsref = 0;
    CGLError error = 0;

    /* Request an OpenGL 3.2 profile if one is available and supported */
    attr[0] = kCGLPFAOpenGLProfile;
    attr[1] = kCGLOGLPVersion_3_2_Core;
    attr[2] = 0;

    error = CGLChoosePixelFormat(attr, &pfobj, &vsref);
    CGLDestroyPixelFormat(pfobj);

    printf("%ld: %s\n", (long)error, CGLErrorString(error));

    return 0;
}

[howarth.at.macports@…]

The new mesa causes pymol to emit …

CGLChoosePixelFormat error: invalid pixel format attribute Abort

What OS version?

[jeremyhu (Jeremy Huddleston Sequoia)]

Ok, at least one case here is with 10.7, so that's odd... 10.7 knows about kCGLPFAOpenGLProfile.

I'm on 10.7 as well

This has nothing to do with your X11 server version. This is an issue inside of mesa.

Can you please break on apple_visual_create_pfobj and figure out what attributes are being requested?

[howarth.at.macports@…]

You're missing debug symbols. You need to build with debug symbols.

In any event, r120374 reverts the change that is causing this while we further triage.

[howarth.at.macports@…]

Okay. I rebuild pymol with…

reinplace "s|\"-O3\",|\"-O3\", \"-g\",|g" ${worksrcpath}/setup.py

added to the post-patch for -g in the compiles but I get the same debug results as above.

[howarth.at.macports@…]

Portfile diff for pymol 1.7.1.1

[howarth.at.macports@…]

Can some please check in the changes in the attached Portfile.diff for pymol and the replacement setup_py.diff and pymol-clang.diff files for me? These changes will update the pymol package to the latest stable release and compile it with -g for further debugging of this problem with the reverted mesa patches. Thanks in advance.

[mf2k (Frank Schima)]

It was applied in r120407.

[mtiberti (Matteo Tiberti)]

I have installed the new version now.. everything works fine for me, with the new mesa package.
