Mike FiedlerProject Lifecycle Status - Quarantine in his "Safety & Security Engineer: First Year in Review postâ Some more info now in Project QuarantineReports of malware in a project kick things offAdmins can now place a project in quarantine, allowing it to be unavailable for install, but still around for analysis.New process allows for packages to go back to normal if the report is false.HoweverSince August, the Quarantine feature has been in use, with PyPI Admins marking ~140 reported projects as Quarantined.Of these, only a single project has exited Quarantine, others have been removed.Michael #3: RESPX
Mock HTTPX with awesome request patterns and response side effects A simple, yet powerful, utility for mocking out the HTTPX, and HTTP Core, libraries.Start by patching HTTPX, using respx.mock, then add request routes to mock responses.For a neater pytest experience, RESPX includes a respx_mock fixtureBrian #4: Unpacking kwargs with custom objects

A surprising thing about PyPI's BigQuery data - HugovkTop PyPI Packages (and therefore also Top pytest Plugins) uses a BigQuery datasetHas grabbed 30-day data of 4,000, then 5,000, then 8,000 packages.Turns out 531,022 packages (amount returned when limit set to a million) is the same cost.SoâŠ. hoping future updates to these âTop âŠâ pages will have way more data. Also, was planning on recording a Test & Code episode on pytest-cov today, but havenât yet. Hopefully at least a couple of new episodes this week.Finally updated pythontest.com with BlueSky links on home page and contact page.Michael:
Follow up from Owen (uv-secure):Thanks for the multiple shout outs! uv-secure just uses the PyPi json API at present to query package vulnerabilities (same as default source for pip audit). I do smash it asynchronously for all dependencies at once... but it still takes a few seconds.Joke: Bugs hide from the light!

Brian #1: Terminals & Shells
Ghostty is outStarted by Mitchel Hashimoto, one of the co-founders of HashicorpâGhostty is a terminal emulator that differentiates itself by being fast, feature-rich, and native. While there are many excellent terminal emulators available, they all force you to choose between speed, features, or native UIs. Ghostty provides all three.âCurrently for macOS & Linux (Windows planned)Version 1.0.1 released Dec 31, announced in OctFeatures: cross-platform, windows, tabs, and splits, Themes, Ligatures, âŠShell Integration: Some Ghostty features require integrating with your shell. Ghostty can automatically inject shell integration for bash, zsh, fish, and elvish.Fish is moving to Rustâfish is a smart and user-friendly command line shell with clever features that just work, without needing an advanced degree in bash scriptology.ââfish 4.0 is a big upgrade. Itâs got lots of new features to make using the command line easier and more enjoyable, such as more natural key binding and expanded history search. And under the hood, weâve rebuilt the foundation in Rust.âMichael #2: Winloop: An Alternative library for uvloop compatibility with windows
via Owen LamontAn alternative library for uvloop compatibility with windows .It always felt disappointing when libuv is available for windows but windows was never compatible with uvloop.Brian #3: Ruff & uv
Ruff 0.9.0 has a new 2025 style guide f-string formatting improvementsNow formats expressions interpolated inside f-string curly bracesQuotes normalized according to project configUnnecessary escapes removedExamines interpolated expressions to see if splitting the string over multiple lines is okOther changes to, but itâs the f-string improvements Iâm excited about.Python 3.14.0a3 is out, and available with uvuv python install 3.14 --previewMichael #4: uv-secure
by Owen Lamont (yes again :) )This tool will scan PyPi dependencies listed in your uv.lock files (or uv generated requirements.txt files) and check for known vulnerabilities listed against those packages and versions in the PyPi json API.I don't intend uv-secure to ever create virtual environments or do dependency resolution - the plan is to leave that all to uv since it does that so well and just target lock files and fully pinned and dependency resolved requirements.txt files).Works âout of the boxâ with a requirements.txt from uv pip compile.Extras

Michael #1: dbos-transact-py
DBOS Transact is a Python library providing ultra-lightweight durable execution.Durable execution means your program is resilient to any failure.If it is ever interrupted or crashes, all your workflows will automatically resume from the last completed step.Under the hood, DBOS Transact works by storing your program's execution state (which workflows are currently executing and which steps they've completed) in a Postgres database.Incredibly fast, for example 25x faster than AWS Step Functions.Brian #2: Typed Python in 2024: Well adopted, yet usability challenges persist

Brian #1: New project to shorten django-admin to django because we are not monsters
Jeff Tripplet has created django-cli-no-admin to shorten django-admin to just django.âOne of the biggest mysteries in Django is why I have to run django-admin from my terminal instead of just running django. Confusingly, django-admin has nothing to do with Djangoâs admin app.âInstead of typing things like: django-admin startproject mysite projectnameWe can type the shorter: django startproject mysite projectnameI love this kind of developer speedup / comfort improvementsAnd yes, Jeff wants Django to eventually include this as the default way to run the command line utilities.Michael #2: django-unicorn: The magical reactive component framework for Django
Add modern site functionality: Quickly add in simple interactions to regular Django templates without learning a new templating language.Skip the JavaScript build toolsNo API required: Skip creating a bunch of serializers and just use Django.Brian #3: Testing some tidbits

Brian #1: Loop targets
Ned BatchelderI donât think I would have covered this had it not been the surprising opposition to Nedâs code.Hereâs the snippet:
params = { "query": QUERY, "page_size": 100,}*# Get page=0, page=1, page=2, ...***for** params["page"] in itertools.count(): data = requests.get(SEARCH_URL, params).json() **if** not data["results"]: **break** ...Ned is utilizing the assignment in the for loop to use the value of count() and store it into the params["page"].
The article includes another version with a temp variable page_num, which I think the naysayers would prefer.But frankly, I think both are fine. Why not put the value right where you want it?Michael #2: asyncstdlib
The asyncstdlib library re-implements functions and classes of the Python standard library to make them compatible with async callables, iterables and context managers. It is fully agnostic to async event loops and seamlessly works with asyncio, third-party libraries such as trio, as well as any custom async event loop.Full set of async versions of advantageous standard library helpers, such as zip, map, enumerate, functools.reduce, itertools.tee, itertools.groupby and many others.Safe handling of async iterators to ensure prompt cleanup, as well as various helpers to simplify safely using custom async iterators.Small but powerful toolset to seamlessly integrate existing sync code into async programs and libraries.Brian #3: Bagels: TUI Expense Tracker
Jax TamâBagels expense tracker is a TUI application where you can track and analyse your money flow, with convenience oriented features and a complete interface.
Why an expense tracker in the terminal? I found it easier to build a habit and keep an accurate track of my expenses if I do it at the end of the day, instead of on the go. So why not in the terminal where it's fast, and I can keep all my data locally?â

Dustin IngramâAttestations provide a verifiable link to an upstream source repository: By signing with the identity of the upstream source repository, such as in the case of an upload of a project built with GitHub Actions, PyPI's support for digital attestations defines a strong and verifiable association between a file on PyPI and the source repository, workflow, and even the commit hash that produced and uploaded the file. Additionally, publishing attestations to a transparency log helps mitigate against both compromise of PyPI and compromise of the projects themselves.âFor maintainersIf using GH Actions and Trusted Publishingmake sure you use pypa/gh-action-pypi-publish, version v1.11.0 or newerthatâs itIf notâSupport for automatic attestation generation and publication from other Trusted Publisher environments is planned.ââWhile not recommended, maintainers can also manually generate and publish attestations.âSee also PyPI Introduces Digital Attestations to Strengthen Python Package Security by Sarah GoodingAre we PEP 740 yet?Michael #3: Django Rusty Templates

Brian #1: Thoughts on Djangoâs Core
Carlton GibsonGreat discussion on Django and Core vs PluginsSustainability with limited peopleKeeping core smallThe release cycleeembrace plugins vs endorsing plugins.Michael #2: futurepool
via Pat DeckerTakes the concept of multiprocessing Pool to the async/await world.Create a pool then delegate the work:
async with FuturePool(2) as fp: result = await fp.map(async_pool_fn, range(10))I would LOVE to see something like this in a broader background asyncio worker pool concept.
But that concept doesnât exist in asyncio in Python and thatâs a failing of the framework IMO.Brian #3: Don't return named tuples in new APIs
Brett CannonFirst off, Iâm grateful for any post that talks about APIs and the API is a module, class, or package API and not a Web/REST API. The term API existed long before the internet.âe.g., get_mouse_position() very likely has a two-item tuple of X and Y coordinates of the screenââit actually makes your API more complex for both you and your users to use. For you, it doubles the data access API surface for your return type as you have to now support index-based and attribute-based data access forever (or until you choose to break your users and change your return type so it doesn't support both approaches)ââ⊠you probably don't want people doing with your return type, like slicing, iterating over all the items âŠâAlternativesclassdataclassdictionaryTypedDictSimpleNamespaceâMy key point in all of this is to prefer readability and ergonomics over brevity in your code. That means avoiding named tuples except where you are expanding to tweaking an existing API where the named tuple improves over the plain tuple that's already being used.âMichael #4: Ziglang: Migrating from AWS to Self-Hosting

Thanks to Pat Decker for the heads up.A rapidly growing number of developers worldwideThis suggests AI isnât just helping more people learn to write code or build software fasterâitâs also attracting and helping more people become developers. First-time open source contributors continue to show wide-scale interest in AI projects. But we arenât seeing signs that AI has hurt open source with low-quality contributions.Python is now the most used language on GitHub as global open source activity continues to extend beyond traditional software development.The rise in Python usage correlates with large communities of people joining the open source community from across the STEM world rather than the traditional community of software developers.Thereâs a continued increase in first-time contributors to open source projects. 1.4 million new developers globally joined open source with a majority contributing to commercially backed and generative AI projects.

Michael #1: Python 3.14.0 alpha 1 is now available
First of seven planned alpha releases.Many new features for Python 3.14 are still being planned and written. Among the new major new features and changes so far:PEP 649: deferred evaluation of annotationsImproved error messagesBrian #2: uv supports dependency groups
we covered dependency groups in episode 406as of 0.4.27, uv supports dependency groupsdocs show how to add dependencies with uv add --groupalso âThe --dev, --only-dev, and --no-dev flags are equivalent to --group dev, --only-group dev, and --no-group dev respectively.âTo install a group, uv pip install --group doesnât work yet. Itâs waiting for PyPA to decide on an interface for pip, and uv pip will use that interface.But sync works.$ uv init # create a pyproject.toml$ uv add --group foo pytest$ uv venv # create venv$ uv sync --group foo # will install all dependencies, including group "foo"Michael #3: dive: A tool for exploring each layer in a docker image
via Mike FiedlerFeatures:Show Docker image contents broken down by layerIndicate what's changed in each layerEstimate "image efficiency"Quick build/analysis cyclesCI IntegrationBrian #4: pytest-metadata
An incredibly useful plugin for adding, you guessed it, metadata, to your pytest results.Required for pytest-html but also useful on itâs ownAdds metadata totext output with --verbosexml output when using --junit-xml, handy for CI systems that support junit.xmlOther plugins depend on this and report in other ways, such as pytest-htmlBy default, already grabsPython versionPlatform infoList of installed packagesList of installed pytest pluginsYou can add your own metadataYou can access all metadata (and add to it) from tests, fixtures, and hook functions via a metadata fixture.This is in the Top pytest Plugins list, currently #5.Extras
Brian:
Iâve started filtering deprecated plugins from the pytest plugin list.Iâm also going to start reviewing the list and pulling out interesting plugins as the topic of the next season of Test & Code.Michael:
