about issue #51 pyglet.gl.ContextException: Could not create GL context

[Jason Spashett]

I've been getting this issue regualrly on all linux installations while playing with pyglet. I see it's fixed now in the repository but it's not in pypi yet. I have a few miscellanous questions:

presumably it will get a pypi update for this at some point

The issue has been present since 2008, the first commit, how come it's only surfaced now? Is it  the result of glx or other changes?

I ask these questions as I am thinking of using pyglet for a comercial project for a client, and of course I am a little aprehensive in case i run into trouble with pyglet.

However, pyglet seems to be exactly what I need, unless I waste effort going the DIY route.

I saw some rumors of pyglets demise, but perhaps the project just needs more contributors.

Thanks,

Jason

Hi,

I will probably create a new 1.2.x bugfix version with some of the latest fixes as it will probably take some time to stabilize 1.3.

Issue #51 was caused by in incorrect interpretation of the GLX api. It probably surfaced due to changes in GLX. Pyglet was incorrectly using some value inside an opaque struct. The contents of this struct are for GLX internal only, so they can change without warning. Probably the value read by pyglet did change, causing the issues. I must say when I read the API docs I was also confused by the description and at first thought pyglet was right.

Pyglet did hit a rough patch some time ago, because simply nobody had time to maintain it. Recently I started maintaining it and released the 1.2.x versions. For 1.3 I am focussing on improving the quality and test coverage and making it easier to maintain Py2 and Py3 compatibility using python future. 

But currently I am still mostly on my own, so more contributors are definitely welcome. Don't hesitate to create pull requests, I will evaluate them and pull them in. Until now I was only able to support Linux and Windows, but as of this week I also have Mac hardware to test and develop on (for my day job I have to support Linux, Windows, Android and since recently OSX  and iOS).

I hope we can make pyglet the best Python OpenGL framework out there ;-)

Hello Rob,

Thanks for your reply. A lot of people seem to like pyglet, and I think it somehow needs more visibility. Perhaps publishing a new 1.2 release and announcing this around on reddit or hacker news might help a bit to get more people interested.

I will have a look at the bug tracker and see what I could fix. I don't know yet if I will be using pyglet for the upcoming project though. It's menuing with some 2d graphics for an appliance and they want it asap (as usual). :-)
