So I'm currently trying to figure out why the PyOpenGL 3.12 test suite is failing. There's a particular test that looks for VBO memory leakage and it looks loosely like this:

for i in range(100):
    create_a_vbo_and_delete_it()
    calculate_total_process_memory()
    assert_no_leak()

It seems that we've removed an entry point that pip 22.0 uses from Python 3.12. That means that you need to install pip from get-pip.py on Ubuntu LTS python3.12.

However even with that done and tox supposedly configured to use pip 23.2.1 in its virtualenvs, I still wind up with pip 22.0 in the ...

So starting to think about a PyOpenGL 4.x release, which would be first to drop Python 2.7 support, so the first one where type-hints can be used to declare metadata for type-coercion (vs the current nonstandard type declarations). The first big question that comes up is:

Given an open collection of types {A,B,C,...}
And a ...

So I spent some of the Victoria Day weekend on PyOpenGL. Biggest changes are:

* got cibuildwheel running on github actions so that we can get a matrix of (manylinux) wheels built for accelerate
* automated upload from github actions to pypi
* investigate the egl regressions; so far all of them seem to be ...

So trying to spend a bit of my vacation going through PyOpenGL issues. So far the biggest issues are all EGL related, with the one currently stumping me is that we do not seem to be able to do an eglMakeCurrent (getting an EGL_BAD_ACCESS) even though the context/view is only ever accessed from the pygame ...

In Pycraft, I figured out the Potions-with-custom-effects, the problem being that Bukkit's PotionEffectType doesn't actually implement the keyed interface, but instead has its own .values() call, so needs a whole special handler. The code for creating potion with custom effects looks like:

    await potion_of(
            'night_vision',
            "Gopher's Gruel",
            {
                'type': 'fast_digging',
                'duration': 20 * 60 * ...

So one of the long-standing requests from the boys has been that we have the ability to create potions from Pycraft's in-game REPL. Today I finally got that working, mostly because I finally decided that there was room for a reference pattern to make the whole thing easier.

By way of background, Pycraft was previously ...

Pycraft has remained relatively obscure. It lets you write (very close to) Python code in the minecraft chat window to perform magic that's written in Python code on the backend. I thought maybe a few demos showing what you can do with the code might serve to interest a few others in playing with it. ...

As a general rule, I don't like to just stop supporting Python releases just for the sake of deprecation. I try to be relatively wide in the set of Python's I'll support for my libraries, with my current general rule being 2.7, 3.6+ .

Why those? Well, 2.7 is still on RHEL/Centos for another year ...

Spent a bit of my second-last-day-of-vacation cleaning up the PyOpenGL Demos so that they run with current Python 3.10, PyOpenGL, numpy and PIL and can be installed as a package rather than only being usable via a git checkout.

There were a few bits of bit-rot, mostly around ctypes no longer allowing you to raise ...
