When trying to run one of the pict3d examples from the command line (the same from DrRacket) the process crashes and I get the output. below.

I am running racket 6.1.1 on SuSE Linux SLED11SP3.

./racket ~/.racket/6.1.1/pkgs/pict3d/pict3d/tests/spheres-on-canvas.rkt cpu time: 2672 real time: 2678 gc time: 856 The program 'spheres-on-canvas.rkt' received an X Window System error. This probably reflects a bug in the program. The error was 'GLXBadContext'. (Details: serial 265 error_code 144 request_code 135 minor_code 5) (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.) libxcb: WARNING! Program tries to lock an already locked connection, which indicates a programming error. There will be no further warnings about this issue.

What happens when you run this instead?

./gracket -synchronous ~/.racket/6.1.1/pkgs/pict3d/pict3d/tests/spheres-on-canvas.rkt

I tried and get the same error:

Believe it or not, that's a good thing. It means that if we have to, we can get a stack trace that leads from the actual error.

A few questions. First, do you have Xinerama? If you do, what happens when you disable it?

Second, what does running this program do?

#lang racket

(require racket/gui
         sgl/gl)

(define frame (new frame% [label "Test"] [width 400] [height 400]))
(define canvas (new canvas% [parent frame] [style '(gl no-autoclear)]))
(send frame show #t)

(define ctxt (send (send canvas get-dc) get-gl-context))
(send ctxt call-as-current
      (λ () (with-handlers ([exn?  (λ (e) e)])
              (glGetString GL_VERSION))))

(send frame show #f)

Also, not a solution, but possibly a workaround or a way to tell whether locking is the only problem:

LIBXCB_ALLOW_SLOPPY_LOCK=1 ./racket ~/.racket/6.1.1/pkgs/pict3d/pict3d/tests/spheres-on-canvas.rkt

Xinerama is disabled.

Second, what does running this program do?

Shortly shows a window and writes the version string on the console: "3.3.0 NVIDIA 319.60"

(define frame (new frame% [label "Test"] [width 400] [height 400])) (define canvas (new canvas% [parent frame] [style '(gl no-autoclear)])) (send frame show #t)

(define ctxt (send (send canvas get-dc) get-gl-context)) (send ctxt call-as-current (λ () (with-handlers ([exn? (λ (e) e)]) (glGetString GL_VERSION))))

Does not make a difference ...

A couple more questions.

Can you run glxgears and glxinfo? What kind of NVIDIA card do you have?

Now we're getting somewhere! Can you reply with the output of glxinfo please? This will help me determine whether it's a driver issue.

Also, a new program for you to try:

lang racket

(require racket/gui)

(define config (new gl-config%)) (send config set-legacy? #f)

(define frame (new frame% [label "Test"] [width 400] [height 400])) (define canvas (new canvas% [parent frame] [style '(gl no-autoclear)] [gl-config config])) (send frame show #t)

Basically, it's the program you just ran, but without the call to glGetString.

Reply to this email directly or view it on GitHubhttps://github.com/ntoronto/pict3d/issues/8#issuecomment-74234397.

Thanks for pasting the glxinfo output again. :)

I think I can fix this, but possibly not by changing Pict3D. Fortunately, there's a workaround. Start your programs like this:

#lang racket
(require pict3d)
(pict3d-legacy-contexts? #t)  ; don't request a core profile

They shouldn't crash if you do that. (Do try it and let me know.)

The root of the problem starts with the fact that your graphics driver won't return OpenGL contexts with core profiles, which Pict3D requests by default. I can tell from the glxinfo output, which contains nothing like the following, which my graphics driver returns:

[...]
OpenGL vendor string: Intel Open Source Technology Center

There's nothing wrong with the driver not returning core profiles when requested. Racket is supposed to request a non-core profile when that happens. Apparently, though, something like one of these things is happening:

Racket isn't falling back to requesting non-core profiles correctly on Linux
The graphics driver is failing to signal an error when it doesn't return a core profile

If I can work around it in Pict3D, I'll do it, and then dive back into Racket's GLX code and try to do the same there.

I think I've worked around the driver problem. Can you try the latest Pict3D when you next get a chance? In particular, try this program:

#lang racket

(require racket/gui
         pict3d)

(pict3d-legacy-contexts? #f)

(define frame (new frame% [label "Test"] [width 400] [height 400]))
(define canvas (new pict3d-canvas% [parent frame]))
(send frame show #t)

(send canvas set-pict3d
      (combine (basis 'camera (point-at '(1 1 1) '(-1 -1 -1)))
               (light '(1/2 1/2 2) "azure" 1)
               (sphere '(0 0 0) 3/4)))

I have updated the pict3d package and now this program runs and displays a window with a gray sphere in it.

I also tested some of the package's example programs but they only work when I add the (pict3d-legacy-contexts? #t) Otherwise they run only for a short time and then crash.

We're making progress!

Can you please run PLTSTDERR="info@pict3d" ./racket ~/.racket/6.1.1/pkgs/pict3d/pict3d/tests/nuclear-sausage-plant.rkt and post the output? It should look something like this:

pict3d: <engine> running X11 version test
pict3d: <engine> obtained canvas OpenGL 33 core context (legacy? = #f)
pict3d: <canvas> obtained canvas OpenGL 33 core context (legacy? = #f)
pict3d: <engine> creating draw-passes vector for 512 shapes
pict3d: <engine> creating sphere opaque color pass program
[...]

Except it should have something about an exception querying the OpenGL context version, followed by lines that indicate it has switched to trying legacy? = #t.

It looks like the segfault is happening when Racket tries to clean up the original OpenGL context. The GLXBadContext crash had been keeping the segfault from happening.

It looks like this is something I have to try to fix in Racket instead of hacking around in Pict3D.

nodrygo commented 9 years ago

don't know if that help but

Same error on my Mint17 (Ubuntu) since I have re installed racket with last snapshot (2015-03-15) 64-bit x86_64 natipkg and updated pict3d

a previous install of racket(version 6.1.1.8--2015-03-11(33d6531/a) [3m].) and pict3d at same time was working fine. when reverting to that 2 releases (racket and pict3d) it work again

NB: plt-game 3D jewel still work glxgears also

~/racket/bin/gracket -synchronous ~/.racket/snapshot/pkgs/pict3d/pict3d/tests/spheres-on-canvas.rkt cpu time: 2628 real time: 2625 gc time: 734 The program 'spheres-on-canvas.rkt' received an X Window System error. This probably reflects a bug in the program. The error was 'GLXBadFBConfig'. (Details: serial 422 error_code 178 request_code 155 minor_code 34) (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.)

ntoronto commented 9 years ago

The reason Racket versions previous to 6.1.1 work is that those versions never asked for core profiles (i.e. they disregarded the legacy? flag in gl-config%).

Can you please paste in the output of glxinfo? I have a couple of hunches I'd like to verify.

ntoronto commented 9 years ago

@nodrygo, @bbaeuml: I've just pushed a possible fix to Racket. It should be in the next snapshot build.

thank's will test on next snapshot

@nodrygo: Thanks! When you do try it, can you please run DrRacket from the command line like this?

PLTSTDERR=info <bin-path>/drracket

I've added some info-level logging whose output will be useful whether the fix works or not - but especially if the fix doesn't work.

ntoronto commented 9 years ago

Oh, and please reply with the logging lines that start with gl-context: or pict3d:.

EDIT: Duh. Instead of manually filtering, use grep:

PLTSTDERR=info <bin-path>/drracket 2>&1 | grep "^pict3d:\|^gl-context:"

Hello, hope that may help (and congrat for this impressive work)

Run with nativepkg

last lines without the grep cm-accomplice: file dependency: #<path:/home/ygo/.racket/snapshot/pkgs/pict3d/pict3d/private/gui/invisible-context.rkt> The program 'drracket' received an X Window System error. This probably reflects a bug in the program. The error was 'GLXBadFBConfig'. (Details: serial 9113 error_code 178 request_code 155 minor_code 34) (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.)

By he way I had another error running tests spaceship and nuclear sausage in dialog box

note

for spaceship the error is at start
for nuclear sauge work (slow lot af GC pause) and the error appear when clossing the window

ntoronto commented 9 years ago

I think I know how to work around the "spaceship" and "nuclear-sausage-plant" problem: copy them into a new file, close them, and run the new file. Either that, or uncheck "Populate compiled directories" in the language dialog.

DrRacket um, helpfully recompiles all of Pict3D when "Populate compiled directories" is checked and one of Pict3D's test files is open. This isn't usually a problem, but it started doing so badly a little while ago. I think I know why, but I don't know how to make it behave.

nodrygo commented 9 years ago

oh yes this work around work thanks

From looking at the program output, it looks like the snapshot with my changes to how Linux gets OpenGL contexts hasn't been built yet. It should look like this:

gl-context: glXCreateContextAttribsARB returned NULL for version 4.5
gl-context: glXCreateContextAttribsARB returned NULL for version 4.4
gl-context: glXCreateContextAttribsARB returned NULL for version 4.3
gl-context: glXCreateContextAttribsARB returned NULL for version 4.2
gl-context: glXCreateContextAttribsARB returned NULL for version 4.1
gl-context: glXCreateContextAttribsARB returned NULL for version 4.0
pict3d: <engine> got canvas OpenGL 33 context (legacy? = #f)
...

At least, there should be 6 lines starting with gl-context: before Pict3D reports that it got an OpenGL context. (They may say something different on your machine.) So we'll have to wait for a snapshot that starts with "20150317". I don't know when it'll be ready, but I assume within a couple of hours.

ntoronto commented 9 years ago

Good! I'm glad the weird problem you had was the same as my weird problem. :D

ntoronto commented 9 years ago

The new snapshots are up at http://pre.racket-lang.org/installers/.

bbaeuml commented 9 years ago

I tested and the examples seem to work. But I get the following messages when, e.g., running the snowman:

Awesome!

Your graphics driver is indeed behaving contrary to standards. It should return NULL and raise an X error when glXCreateContextAttribsARB is called requesting an OpenGL version the driver doesn't support. But it only raises an error, and returns a garbage context. Previously, Racket would check only the return value and ignore the errors, which it should have been able to do, but the garbage context was eventually resulting in segfaults.

In the future, I might change the log level for that message from error to warning so your command line doesn't get spammed with it when you use Pict3D.

Can you run DrRacket using

PLTSTDERR=info <bin-path>/drracket 2>&1 | grep "^pict3d:\|^gl-context:"

and reply with the results up until Pict3D reports that it got an OpenGL context? I want to make sure it's either getting a core profile or correctly falling back to requesting a compatibility profile.

nodrygo commented 9 years ago

just for information on last release 6.1.1.8--2015-03-17(e6ffbf2/a) work fine with: 64-bit x86_64 still hard fail with: 64-bit x8664 natipkg so there is a problem with native pkg .. (not a problem for me because don't really need it ;-) )_

@bbaeuml: Interesting! From the output of glxinfo, I had assumed that your driver wouldn't return a core profile. Knowing NVIDIA, it's probably a compatibility profile that they claim is core. That's OK, though, because Pict3D won't use any of the extra non-core features. :)

@nodrygo: Good to know about the native library build. Even though you don't need it, I'd still like to fix it. I've asked Matthew Flatt about the libraries in it.

ntoronto commented 9 years ago

OK, I've decided to not descend into library dependency hell. Closing this issue. Thanks for your help, guys!
