#Pydantic for Experts: Discriminated Unions in Pydantic V2
https://blog.det.life/pydantic-for-experts-discriminated-unions-in-pydantic-v2-2d9…

These is one of these days when it occurs to you: "hey, packages using #Python and #RustLang, may have *both* Python and Cargo-level tests." And then you spend a lot of time going over all Rust-enabled dev-python/* packages and adding `cargo_src_test` where appropriate.
As it turns out, many of them did. Most of these don't actually link to libpython, so I suppose it's fine to test them once. Pydantic-core does, so I test per-impl (but also can't test on PyPy). Cryptography has Rust-level tests that don't even build (they fail at linking).

Automatic Generation of Python Programs Using Context-Free Grammars
In recent years, data has emerged as the new gold, serving as a powerful tool for creating intelligent systems. However, procuring high-quality data remains challenging, especially for code. To address this, we developed TinyPy Generator, a tool that generates random Python programs using a context-free grammar. The generated programs are guaranteed to be correct by construction. Our system uses custom production rules (in the Backus-Naur Form (BNF) format) to recursively generate code. This al…

Defects are a universal feature of crystalline solids, dictating the key properties and performance of many functional materials. Given their crucial importance yet inherent difficulty in measuring experimentally, computational methods (such as DFT and ML/classical force-fields) are widely used to predict defect behaviour at the atomic level and the resultant impact on macroscopic properties.

Cross-ecosystem categorization: A manual-curation protocol for the categorization of Java Maven libraries along Python PyPI Topics
Context: Software of different functional categories, such as text processing vs. networking, has different profiles in terms of metrics like security and updates. Using popularity to compare e.g. Java vs. Python libraries might give a skewed perspective, as the categories of the most popular software vary from one ecosystem to the next. How can one compare libraries datasets across software ecosystems, when not even the category names are uniform among them? Objective: We study how to generate…

This method is particularly tailored for high redshift studies and thereby relies on the observed high-redshift galaxy luminosity functions and …

Here's my newest optimization idea for #Gentoo #Python: for pure Python packages and packages using the stable #CPython API, let's reuse previously built wheels if they're compatible instead of building them separately for each Python implementation.
This is mostly a major gain for the lot of packages using #setuptools when you're using multiple PYTHON_TARGETS, since calling into that build system has a significant cost. However, it also saves some actual compiling in the packages using the stable API (particularly, Rust packages).

#Python PEP 744 – #JITCompilation
https://peps.python.org/pep-0744/

New on blog: "the story of #distutils build directory in #Gentoo".
"""
The #Python distutils build system, as well as #setuptools (that it was later merged into), used a two-stage build: first, a build command would prepare a built package version (usually just copy the .py files, sometimes compile Python extensions) into a build directory, then an install command would copy them to the live filesystem, or a staging directory. Curious enough, distutils were an early adopter of out-of-source builds — when used right (which often enough wasn’t the case), no writes would occur in the source directory and all modifications would be done directly in the build directory.
Today, in the #PEP517 era, two-stage builds aren't really relevant anymore. Build systems were turned into black boxes that spew wheels. However, setuptools still internally uses the two-stage build and the build directory, and therefore it still remains relevant to Gentoo eclasses. In this post, I'd like to shortly tell how we dealt with it over the years.

I’m very happy to announce build-and-inspect-python-package 2.1.0!
The two highlights are: 1. it’s faster courtesy of uv and 2. it allows you define your strategy matrix based on your trove classifiers!

I've done some benchmarks to demonstrate how different versions of #Gentoo parallel #Python extension builds (using #setuptools) #PEP517 code in distutils-r1.eclass improved over the years. I've even copied the numbers into a gnumeric spreadsheet. Now I just need to find energy to make a nice chart out of that (probably using PGF/Tikz).
Some numbers for a rough idea:
Cython 3.0.9 (package with a few C extensions):
- serial PEP517 build: 46.7 s
- parallel build / build_ext PEP517: 20.8 s 2.7 s
- parallel PEP517 via DIST_EXTRA_CONFIG: 22.8 s
django 5.0.3 (moderate pure .py package):
- PEP517 build: 5.4 s
- unnecessary build PEP517: 3.1 s 5.3 s
- unnecessary build_ext PEP517: 0.6 s 5.4 s

I've added #Python 3.13.0b1 to #Gentoo yesterday, along with the initial eclass support and a few baseline ports (up to PyTest).
It's amd64-only for the time being, since we need to keyword mpdecimal.

Did you notice that the word "backslashes" includes "lashes"? That's precisely how I feel about people using unnecessary backslashes all over the place in #Python or #Bash code.

On 2024-03-19, two vulnerabilities were announced on #Python #security mailing list: "quoted zip-bomb" and "TemporaryDirectory symlink dereference during cleanup". Both were announced to affect all current #CPython releases.
The same day, security releases were made for Python 3.10, 3.9 and 3.8 branches. So far, so good. However, I found it surprising that there were no releases being made for 3.11 or 3.12.
On 2024-04-02, Python 3.11.9 was tagged. Initially, the signature on source tarball didn't verify. Today, it does verify, but the release still doesn't seem to have been announced. However, what I found the most surprising is the lack of fixes for the security issues announced before! Was the release borked?
So I've checked in more detail… and it turned out that both issues were already fixed in 3.11.8 (and 3.12.2), so the security announcement was wrong. Sigh.
That said, #PyPy is still affected.
