I don't often write #python but when I do I can apparently write python inefficient enough to start the fans spinning on my workstation for half an hour. It looks like Path's match involves a glob compile for every invocation and I have a lot of files (14k) to check against a lot of patterns (2314).

I got some Python code working yesterday after being convinced I could not figure it out… but figured it out!
Realized I needed extra code today, thought it would be a pain but figured it out in no time.
Maybe I can write Python okay…

Also, zero days (well, minus a lot of days because I've been slacking) since a random #Python package got a new #NIH dependency on another Python package which is actually a "fastest" #RustLang package which cannot be built because the author thinks it a great idea to require a nightly Rust compiler.
…and of course it's full of "unsafe" calls. Because Rust is obviously such a great language for making secure code.

Good morning! Since it's become a drag to support in mainline, I've extracted svcs's Pyramid support into an own package svcs-pyramid.
That means, the next svcs version will ship WITHOUT a `svcs.pyramid` module.
You can start using svcs-pyramid TODAY to avoid breakage the moment 26.2.0 drops – there are no code changes, just adjust the import statement:

Zero days since I've discovered a random #CPython bug that triggers in very specific circumstances and I don't really have time to report it, nor can expect anyone to do it for me.
This time it's a test failure and refcounts being broken while running fastjsonschema's test suite on #Python 3.15 freethreading with pytest's --junit-xml option enabled 😱. And of course removing --junit-xml makes all tests pass.
EDIT: and of course I cannot reproduce outside Portage. Yet inside, it reliably crashes every single time.

A cool recent #Python change is PEP 783 <#pyodide

It's kind of crazy that both GPT and Claude really love to manipulate files by writing Python scripts that do text search-and-replace. First of all, why isn't this a dedicated tool? Second, the generated scripts usually don't check that the search-and-replace was successful. Are they just good enough at regurgitating text that they never make mistakes? What if the file was modified in the mean time?

2. Everyone starts depending on third-party TOML libraries.
3. TOML library is finally added to the standard library, so people are moving to conditionally using it.
4. As old versions of Python become irrelevant, people are finally dropping fallbacks to the third-party library.
5. TOML 1.1 is introduced, and everyone has to start using a third-party library again… (at least until Python 3.15)
That's in case anyone is wondering why dev-python/tomli is suddenly getting installed on #Gentoo systems again.

There is only a handful of human projects left (Flask being one bright example). And they're being killed. They're being killed by the neverending slew of slop pull requests. They're being killed by all their dependencies becoming slop. They're being killed because this whole ecosystem has became such a complete cesspit that you have zero motivation to do anything.
EDIT: and honestly, this is only going to get worse. When you kill the incentive to work on projects, you only get more slop. Maintainers give in, and more projects become slop. Or they give up, and projects get forked unto slop.

#Python Hypothesis package now requires #RustLang. This is a scale of reverse dependencies I can't handle. I guess this means it's the end of WD40 profiles on #Gentoo, and therefore the end of support for Alpha, ARM<v6, HPPA, M68k, i486 and some other random subsets of architectures and profiles. Thanks for all the fish, etc.
https://github.com/HypothesisWorks/hypothesis/issues/4740

And the next big blocker for #Python 3.15 in #Gentoo is time-machine. Which is obviously broken. There's a patch but it's #slop and complex, and it's sitting for 3 months already with no reply. Because obviously patching CPython internals is so much a better idea than freezegun ever were. All these time-based tests need all the ricing you can get; portability doesn't matter.
https://github.com/adamchainz/time-machine/pull/618

Challenge: have a #Python package use the same environment variable to disable building extension and to make tests not expect extension.
Difficulty: impossible.

So now that #awscli 1.x is pretty much dead, I've finally gotten around to packaging 2.x properly for #Gentoo. You know, the one where other developers claimed it was impossible to build from source because (checks notes) upstream said so. So we instead must use their horrible 70M binary package that bundles its own Python interpreter along with all the random libraries and dependencies.
And guess what? Sure, they don't publish it to PyPI anymore, but it still is a regular #Python package branched out from 1.x. It has regular Python package dependencies, a regular Python build backend and when you build it with it, you get a regular Python wheel that can be installed and just works with the system Python and system dependencies.
Sure, it's crap, but it's no worse than the 1.x crap. It bundles a modified fork of the unreleased 2.x branch of botocore (now dead for 5 years, apparently) and a fork of s3transfer. It has some random meaningless dependency pins that we patch out. It has a horrible test suite that can eat tons of memory if run via xdist, but with some hackery, I've gotten it to work reasonably.
Honestly, I feel like Gentoo developers these days just don't care to even try.
