gaffer crashes after creating an arbitary node #1245

Closed leonard7e closed 6 years ago

leonard7e commented 9 years ago

Hi.

I have problems to create a node in gaffer.

My system.

Using Fedora 21 linux.

$ cat /proc/version Linux version 3.17.7-300.fc21.x86_64 (mockbuild@bkernel01.phx2.fedoraproject.org) (gcc version 4.9.2 20141101 (Red Hat 4.9.2-1) (GCC) ) #1 SMP Wed Dec 17 03:08:44 UTC 2014

Running Gaffer.

I get these errors on startup.

ERROR : IECore.loadConfig : Error executing file "/home/lsiebeneicher/opt/pkg/gaffer_precompiled/gaffer-0.10.0.0-linux/startup/gui/ocio.py" - "The specified transform file '/home/lsiebeneicher/opt/pkg/gaffer_precompiled/gaffer-0.10.0.0-linux/openColorIO/luts/srgb.spi1d' could not be loaded. Invalid 'From' Tag". Traceback (most recent call last): File "/home/lsiebeneicher/opt/pkg/gaffer_precompiled/gaffer-0.10.0.0-linux/python/IECore/ConfigLoader.py", line 68, in loadConfig execfile( fullFileName, contextDict, contextDict ) File "/home/lsiebeneicher/opt/pkg/gaffer_precompiled/gaffer-0.10.0.0-linux/startup/gui/ocio.py", line 82, in __setDisplayTransform() File "/home/lsiebeneicher/opt/pkg/gaffer_precompiled/gaffer-0.10.0.0-linux/startup/gui/ocio.py", line 73, in __setDisplayTransform processor = config.getProcessor( OCIO.Constants.ROLE_SCENE_LINEAR, colorSpace )

Now I try to create an arbitary node. Gaffer crashes immediately. Message:

terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc

Tried these versions

0.8.2.0 || 0.9.0.0 || 0.10.0.0 (downloaded, precompiled)

Compiled and tried 0.11.0.0 same issue, gaffer crashes if I create a node.

A bit of googling seems to suggest that the startup error may come from a bug in OpenColorIO :

https://github.com/imageworks/OpenColorIO/issues/297 https://github.com/imageworks/OpenColorIO/issues/379

Is it possible you might be hitting that, or are you running with an english locale (which would suggest there is another problem).

As for the crash, I wonder if you could provide us with a stack trace to help us track it down? If you run Gaffer with env GAFFER_DEBUG=1 gaffer, that'll load Gaffer in the gdb debugger. You can then enter r to run it, and when it crashes, enter bt to get a stack trace. If you could post that here we will hopefully be able to get to the root of the problem…

Cheers… John

Hi John,

I had German locales. Changed to english locales.

Now localectl gives

System Locale: LANG=en_US.utf8 VC Keymap: us-euro X11 Layout: en,en

Same issues with ocio.

I edited some files , removed line with FROM manually. All errors relating to OpenColorIO disappeared.

But gaffer still crashes if I create a node

terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc

Regards, Leonard

gdb log ( llines with FROM removed from ocio data files )

Are you running Gaffer in a laptop that has Nvidia optimus? Or maybe a VM?

leonard7e commented 9 years ago

Hi Esteban

Gaffer runs on a desktop pc. But my computer uses a nvidia quadro 600. Have troubles to get hardware acceleration drivers working on fedora.

Some time ago I tried to get bumblebee working. But I deinstalled it again.

$ glxinfo | grep -i vendor gives

server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: nouveau

est77 commented 9 years ago

It's unlikely that gaffer runs ok with the noveau drivers. I know for sure that it does not work correctly when using the intel graphics. In my case, it runs but I cannot select nodes when I use the intel gpu.

Try to install the nvidia drivers without using bumblebee.

ghost commented 9 years ago

I get the same thing in VirtualBox. I have been on an epic mission to compile all the dependencies and then build cortex/OSL/appleseed/GafferSeed - but it seems to crash as soon as it tries to draw anything with OpenGL.

As a really crappy workaround if you wish to test out other (non-visual) aspects of gaffer, you can add a 'Display' or an 'Image Read' node, and pin the viewer window to it, this way you can build gaffer graphs, without running into the crash. Not sure how practically helpful that is for actual use.

leonard7e commented 9 years ago

Hi marchingcubes. Trying to create node Image~Source~Display. Crashes immediately.

~~ Sorry, using nvidia proprietary driver is not an option here.

danieldresser commented 9 years ago

I think it's fairly expected behaviour that 3d software won't work with the Nouveau drivers? I accidentally tried Houdini on a system using Nouveau a month back, and it was unusable. There's probably not much we can do about this, without putting large amounts of work into getting things half-working. If you want to run 3d software, you're probably going to have to get the binary nvidia driver working.

ghost commented 9 years ago

Refuse to start if required OpenGL functions not available in the driver, with a clear error message stating that? Sure.

Exiting gracefully with a clear error message if OpenGL rendering fails, OK.

Displaying a 'could not render node with OpenGL' message but continuing to process - best solution.

Appearing to start up and work fine but then segfaulting upon user action leaving no clue to what the problem is? Could be handled better.

Obviously gaffer isn't at '1.0' yet so no big deal, but little things like this (clear error messages, no 'just crash and leave the user to run gdb to ascertain what the problem was') make life much easier

johnhaddon commented 9 years ago

Related to #901 - both are GL compatibility issues.

boberfly commented 9 years ago

Are the nodes being drawn using IECoreGL or does that code live in Gaffer? I remember skimming through and seeing lots of fixed-function immediate API mixed with GL 3.x stuff, which is problematic for anything that doesn't support a compatibility context (I'm surprised it's working on OSX which has been known to be the most strict and without a compatibility context). The open drivers under mesa are quite good these days, so this looks like it can be fixed with more modern approaches to GL (oldschool GL selection picking is gone, if Gaffer relies on this). But yeah, god knows how old CentOS is with mesa+the kernel, recent Ubuntus/Fedoras should have a decent enough driver stack though.

johnhaddon commented 9 years ago

The node drawing code lives mostly in Gaffer, although we do use IECoreGL too. And we do use a nasty mix of old-skool OpenGL and more modern stuff in both Gaffer and IECoreGL. We actually target OpenGL 2.1 but using a lot of extensions which give us most of what we need from OpenGL 3 - that's how we manage to get things to work on OSX, where there is absolutely no compatibility context. At some point we need to bite the bullet and move everything over to pure OpenGL 3+, but as always, it's about finding time...

johnhaddon commented 6 years ago

We've just released Gaffer 0.45, which includes a bugfix for an LLVM conflict that I believe is the most likely cause of this issue. Closing somewhat speculatively - please reopen if testing in 0.45.0.0 reveals the problem persists.

leonard7e commented 6 years ago

Trying, Gaffer did not crash after creating several nodes. Thank you for your effort.
