Yes, I abuse f-strings in python because "print(f'" will always make more sense to my C-poisoned brain than "print('".

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.

It's always important to have a consistent #security policy.
For example, a policy of "If somebody filed a CVE, it's an important security issue, and we will fix it as such, no matter how meaningless the fix is. If nobody did, it's just a glorified bug fix, no matter how serious the bug was."
So we've just seen a #pip security release over "installing random packages can overwrite pip's files and pip can lazy-import some of them immediately afterwards", with a fix of "pip will no longer load them until you run it again" (leaving the underlying security issue of "any #Python package can override files installed by any other Python package" as intended behavior). As Eli Schwartz beautifully put it, you are not expected to be using the virtual environment; you should create it, install packages into it (at most once!), and then frame it and put it on the wall to admire.
Now we're seeing a "bug fix" for "malicious entry point names can write outside of virtual environment". If nobody filed a CVE, it's obviously not a security issue at all. At least upstream graced us with fixing it without correcting the spec to forbid that first.

Agent libOS: A Library-OS-Inspired Runtime for Long-Running, Capability-Controlled LLM Agents
Yingqi Zhang
https://arxiv.org/abs/2606.03895 https://arxiv.org/pdf/2606.03895 https://arxiv.org/html/2606.03895
arXiv:2606.03895v1 Announce Type: new
Abstract: Large language model (LLM) agents are evolving from request-response assistants into long-running software actors: they maintain state across model calls, fork subtasks, wait for external events, request human authority, generate tools, and perform side effects that must be resumed and audited. This paper presents Agent libOS, a library-OS-inspired runtime substrate for LLM agents. Agent libOS runs above a conventional host operating system; it does not implement hardware drivers, kernel-mode isolation, or a POSIX-compatible operating system. Instead, it treats an agent as an AgentProcess: a schedulable execution subject with process identity, parent-child lineage, lifecycle state, a tool table derived from an AgentImage, typed Object Memory, explicit capabilities, human queues, checkpoints, events, and audit records. Its central design rule is tools are libc-like wrappers; runtime primitives are the authority boundary. Filesystem access, object access, sleeps, human approval, JIT tool registration, and external side effects are checked at primitive boundaries under explicit capabilities and policy.
We describe the design, threat model, Python prototype, and safety-oriented evaluation. The current prototype implements async scheduling, namespace-local Object Memory, runtime-integrated human approval, one-shot permission grants, per-process working directories, shell and image-registration primitives, Deno/TypeScript JIT tools over a libOS syscall broker, filesystem/object bridge tools, an injectable Resource Provider Substrate, deterministic demos, real-model smoke scripts, and 123 regression tests at the time of writing. Rather than improving planner accuracy, Agent libOS demonstrates a runtime substrate in which long-running LLM agents can be scheduled, authorized, resumed, and audited without treating tool dispatch as the trust boundary.

Joint elastic full waveform inversion of multi-component geophone and distributed acoustic sensing data
Hoang Anh Nguyen, Ali Tura
https://arxiv.org/abs/2607.01649 https://arxiv.org/pdf/2607.01649 https://arxiv.org/html/2607.01649
arXiv:2607.01649v1 Announce Type: new
Abstract: Joint full waveform inversion (FWI) of distributed acoustic sensing (DAS) and ocean-bottom node (OBN) data typically requires converting measured strain to particle velocity, introducing numerical noise and spectral distortion. To eliminate this, we present an elastic multi-parameter FWI framework using a velocity-stress-strain (VSS) formulation that directly models pressure, particle velocity, and gauge-length-averaged DAS strain from a single forward simulation. Data residuals are injected additively into a single backward simulation, making computational cost independent of the active sensor subsets. We benchmark individual and combined datasets on cross-talk and elastic Marmousi models. Our results show that joint inversion recovers elastic parameters more accurately than single deployments when the sensors offer complementary information. Specifically, pairing two-component geophones with a deviated borehole DAS cable yields the most accurate parameter recovery and mitigates inter-parameter cross-talk by providing a distinct physical observable and complementary depth aperture. We release our implementation as xFWI, an open-source, Devito-based Python package for scalable, multi-deployment inversions.

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.

I wish #mypy would slow down with adding new features to mypyc, and instead focused on fixing the train wreck that mypyc is right now (since 2023 at least). Like, if your code crashes hard with assertions enabled, then it's broken, period. Ignoring proper testing and shoving the issue under the carpet doesn't make it right.
#Python

I've been sad about the upcoming removal of #PyPy from #Gentoo, but given how many regressions I've been seeing recently in a variety of #Python packages, I'm eagerly waiting for the day when I'll remove the support and be able to stop having to deal with the test failures somehow. Not that at this point any other way of dealing besides skipping them makes any sense.

I’m somewhat embarrassed to finally announce svcs 26.1.0 – my solution to #Python service location and dependency injection.
It’s been a minute, and the changelog is chuck-full, but the main features are autowiring, which looked like a simple add-on that grew to a four-digit monster diff, and of course, TypeForms that allow registering/getting abstract types!

Highlights In the spirit of "we do these things not because they are easy, but because we thought they were going to be easy" this release brings a great new feature: autowiring! It resolves depend...

Well, we've finally packaged #Valkey (another #Redis fork) in #Gentoo, along with its #Python bindings.
Not that we wanted to, but #FakeRedis now started requiring it for tests so heavily that it was too much effort to patch it out. Just to be clear, it just requires the Python bindings, because its test suite happily runs against either Redis or Valkey, and literally doesn't support testing against both simultaneously. But to add the bindings, we needed the database to test them against. And since I've added the package too, I've put a lot of effort (and swearing) to test FakeRedis against both servers.
Should you be using Valkey? Well, let's put it like this. You shouldn't be using Redis, because it's enterprise quality shit. Valkey is roughly what happens when you fork enterprise quality shit and have no clue what you're doing. Though you are able to mostly get renaming right (one valkey-py test failed over the server calling itself "Valkey" rather than "Redis").
Disclaimer: I've only looked at the Python bindings. Maybe the maintainers are more knowledgeable with the server itself.

If #Python package releases continue at this rate, I'm going to have to start getting up earlier.
Or just stop doing all of them in the morning.

Always appreciate #Python package developers being responsible about API stability, and… [checks notes]… raising the major version number over a "minor API tweak", then delaying the release until a security fix demanded one.

0 days since provenance checks protected us from [checks notes] another project starting to upload distributions via #uv.

Yes, please reinvent more wheels by rewriting #Python logic in #RustLang. What could possibly go wrong?!

Does anyone happen to know if #PSF is processing contributing membership applications? Mine is stuck with no reply for almost 2 months now, and I'm wondering if it's just normal delay or something went wrong.
