@chrysn@chaos.socialA feature which I'm really looking forward to is brewing in #Python packaging: Specifying default extras.
The aiocoap library I maintain can (and is tested to) work with no other dependencies than Python, but most users will like the additional features such as pretty-printing support, or more security options than just TLS. So far, they have to `pip run --spec "aiocoap[all]" aio…
@mgorny@social.treehouse.systemsBREAKING: #CPython 3.13.10 and 3.14.1 changed the multiprocessing message format in patch release. As a result, programs using multiprocessing may break randomly if they are running while #Python is upgraded (i.e. need restarting).
But apparently it's not a big deal, since all the cool kids are running Python in containers, and nobody is using Python for system tools anymore. Everything has been RIIR-ed and Python is only omnipresent in some backwaters like #Gentoo.

Would you have a specific online tutorial to recommend for someone who wants to learn Python without any prior programming experience? One that also explains how to install it ?

@mgorny@social.treehouse.systemsYeah, why not neglect all the good recommendations in the #Python ecosystem, and instead fork your own C extension package, force people to build it with #ZigLang (it's still C), add unconditional dependency on that, and on top of that, refuse to publish wheels, "allowing for optimised compilation according to your machine's specific architecture and capabilities, instead of some (low performance) common denominator."
Fortunately, looks like #Gentoo can just ignore all the fancy crap and compile it with GCC.

@gedankenstuecke@scholar.socialAs someone who so far just used pipenv for his #Python dependency management (as most of my stuff is web dev that isn't packaged but rather deployed):
If I'd want to write a library that I wanna properly package/release, which dependency manager would you recommend when starting a project from scratch in (the last days of) 2025?

@rasterweb@mastodon.socialYears ago I had this Processing app that I used to create time stamped images from a webcam. It no longer works. (It’s been years since I used it.)
I was able to rewrite what I need in Python fairly easily, so that’s pretty awesome.
I used to really love Processing but I guess I love Python now.

@peter_mcmahan@mas.toI rewrote a data analysis pipeline, moving it from #python to #julialang . I am now in love with the threading support in Julia.
The task is very parallelizable but each thread needs random read access to a tens-of-GB dataset. In Python (with multiprocessing, shared stores, etc) data bookkeeping was a nightmar…

@frankel@mastodon.top @elduvelle@neuromatch.social @hynek@mastodon.socialI’m somewhat exhausted to announce attrs 25.4.0!
The main reason for this release (and why it's published today) is that it ships the first pieces of work for Python 3.14 and PEP 749. There will be more work required and there's going to be a lot more churn once everyone starts testing 3.14 earnestly. We hope to receive more feedback before spending more time on this. #Python

#packaging
@mgorny@social.treehouse.systems#Sphinx joined the list of packages dropping #Python 3.11 (and therefore #PyPy) support. Of course, we could just go through the effort of dropping it from respective packages in #Gentoo, given it's not technically that common… but honestly, at this point I have zero motivation to put the extra effort for this, just to learn that next month some core package starts requiring Python 3.12.
So, would anyone really mind if I removed Python 3.11 and PyPy support completely from Gentoo packages?
@mgorny@social.treehouse.systemsRemember the package that recently had some trailing junk in the .tar.gz that broke GNU tar, and replied to my bug report with a comprehensive #LLM analysis and a slightly sloppy release checking workflow?
They've made a new release and this time the source distribution is completely broken gzip stream.
Honestly, bumping #Python packages for #Gentoo all these years, I don't recall ever seeing a problem with gzip streams. And then, #autobahn starts using #ClaudeCode heavily, and two bad releases in a row. I can't help but consider the project compromised at this point.
#NoAI #AI
@mgorny@social.treehouse.systems @mgorny@social.treehouse.systems @mgorny@social.treehouse.systemsTotally normal #Python upstream attitude:
1. Ignore a reply on a bug report for 3 years.
2. Install a #StaleBot in the middle of the night.
3. 7 minutes after the bug is marked stale, claim that you "never heard back on this" and that "the issue was somewhere downstream", without even checking another linked issue.

@mgorny@social.treehouse.systems🤚 Free Saturday
👉 Saturday spent working on Free Software
Highlights from #Gentoo:
• #Gemato is now compatible with #FreePG and mostly compatible with #SequoiaPGP chameleon.
• Prepared patches to support FreePG and SequoiaPGP chameleon as "gpg" symlink providers.
• #FlexiBLAS is now enabled by default on ~arch.
• Finally finished working on #PkgCheck check for missing #PyPI provenance checks.
• gpy-list-pkg-impls now includes "does this package have tests?" state, can optionally include PythonCompatUpdate results from PkgCheck and output mIRC colors. In other words, our IRC bot will now tell us when dependencies let us port new packages to #Python 3.14, and whether these packages have tests.
@mgorny@social.treehouse.systemsI've filed a report about a minor problem with a #Python package, namely that the source distribution contained some trailing junk that breaks GNU #tar. On one hand, I'm happy that upstream took the issue seriously. On the other hand, I'm terrified of how much #AI slop was involved in the response.
I mean, my short bug report yielded a few walls of text of #LLM analysis of what the cause of the problem might be, of suggested solutions… and praise of the author's fix. These are interspersed with short comments from the author, all pasted under their own personal account. And the linked pull request is also huge, with "verification code" that's quite sloppy (bits that don't do anything, conditions that will never be true… but at least it seems to do what it was supposed to do).
Honestly, I don't know what to do. Not that I ever planned using this package, but at this point I will definitely stay away from it. It's in #Gentoo, and I'll have to continue maintaining it for the sake of reverse dependencies, but I feel like it's unfair to expose our users to packages that have clearly proven to accept AI slop without reviewing it properly. Or rather, AI slop that's being reviewed… by AI. How can anyone think this a good idea?!
There were multiple times in my life when I've considered retiring from Gentoo, for variety of reasons. There were also multiple times when I wanted to get away from computers altogether. Unfortunately, we're living in a truly fucked up world, and there is no escape. The best you can do is put an ever increasing effort to keep fixing all that crap that will just keep piling on faster and faster.
