Support all CPython ABI tag suffixes properly by konstin · Pull Request #17817 · astral-sh/uv

konstin · 2026-02-02T15:02:34Z

Previously, we'd emit false wheel names in (error) messages, e.g. cp314-cp314td-macosx_26_0_arm64 would become cp314-cp314-macosx_26_0_arm64 (#17635). To fix that, we need to properly track CPython ABI tag suffixes.

I've implemented tracking for all four CPython 3 ABI tag suffixes, dubbing them modifiers. Only freethreading actually changes the ABI, debug exists but is ABI compatible nowadays, the rest exists to avoid falsifying wheel we rejected. The bitflags are able to track future ABI additions.

We need to take care here that we bump the right cache buckets.

I ran this through the ecosystem check and it came back clean, these updates happened while the tests were running:

I highlighted a couple of questions where I am a bit confused.

+        }


I'm not sure I completely understand this.
If the m marker was dropped from 3.8 onwards because it was no longer meaningful, and the other link in the other comment says it was still meaningful prior to 3.4, doesn't it make more sense to preserve it for versions before 3.7 or maybe even just 3.4 rather than forcing it set?

Usually, the 3.7 wheels will look like cp37-cp37m-.... main also adds the m for those versions, I've preserved that here.

Hmm, I still don't understand how what the comment says justifies the code, but you are right that it seems that existing tests fail if this isn't forced set here...

This test is missing the error cases.

This seems like it should still be creating a tag using AbiTag::CPython { ... } otherwise the test case on the very next line doesn't make sense.

Removed the duplicate cases.

Previously we weren't printing the tags as part of the version, we were relying on AbiTag's display implementation. And we still are. Does this formatting need to actually change?

This was previously specifically matching on gil_disabled == false, we are dropping that?

Ditto the comments from uv-installer/src/plan.rs.

We can remove that branch, it's covered by the pretty tag.

Can we call them "Variants" just for consistency with the way debug and free-threading are used elsewhere.

I think I'd say

Unknown suffix {suffix} for CPython ABI tag: {tag}

Maybe "in" instead of "for" still?

Follow-up to #17817 (comment)

This MR contains the following updates: | Package | Update | Change | |---|---|---| | [astral-sh/uv](https://github.com/astral-sh/uv) | minor | `0.9.28` → `0.10.0` | MR created with the help of [el-capitano/tools/renovate-bot](https://gitlab.com/el-capitano/tools/renovate-bot). **Proposed changes to behavior should be submitted there as MRs.** --- ### Release Notes <details> <summary>astral-sh/uv (astral-sh/uv)</summary> ### [`v0.10.0`](https://github.com/astral-sh/uv/blob/HEAD/CHANGELOG.md#0100) [Compare Source](astral-sh/uv@0.9.30...0.10.0) Since we released uv [0.9.0](https://github.com/astral-sh/uv/releases/tag/0.9.0) in October of 2025, we've accumulated various changes that improve correctness and user experience, but could break some workflows. This release contains those changes; many have been marked as breaking out of an abundance of caution. We expect most users to be able to upgrade without making changes. This release also includes the stabilization of preview features. Python upgrades are now stable, including the `uv python upgrade` command, `uv python install --upgrade`, and automatically upgrading Python patch versions in virtual environments when a new version is installed. The `add-bounds` and `extra-build-dependencies` settings are now stable. Finally, the `uv workspace dir` and `uv workspace list` utilities for writing scripts against workspace members are now stable. ##### Breaking changes - **Require `--clear` to remove existing virtual environments in `uv venv`** ([#17757](astral-sh/uv#17757)) Previously, `uv venv` would prompt for confirmation before removing an existing virtual environment in interactive contexts, and remove it without confirmation in non-interactive contexts. Now, `uv venv` requires the `--clear` flag to remove an existing virtual environment. A warning for this change was added in [uv 0.8](https://github.com/astral-sh/uv/blob/main/changelogs/0.8.x.md#breaking-changes). You can opt out of this behavior by passing the `--clear` flag or setting `UV_VENV_CLEAR=1`. - **Error if multiple indexes include `default = true`** ([#17011](astral-sh/uv#17011)) Previously, uv would silently accept multiple indexes with `default = true` and use the first one. Now, uv will error if multiple indexes are marked as the default. You cannot opt out of this behavior. Remove `default = true` from all but one index. - **Error when an `explicit` index is unnamed** ([#17777](astral-sh/uv#17777)) Explicit indexes can only be used via the `[tool.uv.sources]` table, which requires referencing the index by name. Previously, uv would silently accept unnamed explicit indexes, which could never be referenced. Now, uv will error if an explicit index does not have a name. You cannot opt out of this behavior. Add a `name` to the explicit index or remove the entry. - **Install alternative Python executables using their implementation name** ([#17756](astral-sh/uv#17756), [#17760](astral-sh/uv#17760)) Previously, `uv python install` would install PyPy, GraalPy, and Pyodide executables with names like `python3.10` into the bin directory. Now, these executables will be named using their implementation name, e.g., `pypy3.10`, `graalpy3.10`, and `pyodide3.12`, to avoid conflicting with CPython installations. You cannot opt out of this behavior. - **Respect global Python version pins in `uv tool run` and `uv tool install`** ([#14112](astral-sh/uv#14112)) Previously, `uv tool run` and `uv tool install` did not respect the global Python version pin (set via `uv python pin --global`). Now, these commands will use the global Python version when no explicit version is requested. For `uv tool install`, if the tool is already installed, the Python version will not change unless `--reinstall` or `--python` is provided. If the tool was previously installed with an explicit `--python` flag, the global pin will not override it. You can opt out of this behavior by providing an explicit `--python` flag. - **Remove Debian Bookworm, Alpine 3.21, and Python 3.8 Docker images** ([#17755](astral-sh/uv#17755)) The Debian Bookworm and Alpine 3.21 images were replaced by Debian Trixie and Alpine 3.22 as defaults in [uv 0.9](astral-sh/uv#15352). These older images are now removed. Python 3.8 images are also removed, as Python 3.8 is no longer supported in the Trixie or Alpine base images. The following image tags are no longer published: - `uv:bookworm`, `uv:bookworm-slim` - `uv:alpine3.21` - `uv:python3.8-*` Use `uv:debian` or `uv:trixie` instead of `uv:bookworm`, `uv:alpine` or `uv:alpine3.22` instead of `uv:alpine3.21`, and a newer Python version instead of `uv:python3.8-*`. - **Drop PPC64 (big endian) builds** ([#17626](astral-sh/uv#17626)) uv no longer provides pre-built binaries for PPC64 (big endian). This platform appears to be largely unused and is only supported on a single manylinux version. PPC64LE (little endian) builds are unaffected. Building uv from source is still supported for this platform. - **Skip generating `activate.csh` for relocatable virtual environments** ([#17759](astral-sh/uv#17759)) Previously, `uv venv --relocatable` would generate an `activate.csh` script that contained hardcoded paths, making it incompatible with relocation. Now, the `activate.csh` script is not generated for relocatable virtual environments. You cannot opt out of this behavior. - **Require username when multiple credentials match a URL** ([#16983](astral-sh/uv#16983)) When using `uv auth login` to store credentials, you can register multiple username and password combinations for the same host. Previously, when uv needed to authenticate and multiple credentials matched the URL (e.g., when retrieving a token with `uv auth token`), uv would pick the first match. Now, uv will error instead. You cannot opt out of this behavior. Include the username in the request, e.g., `uv auth token --username foo example.com`. - **Avoid invalidating the lockfile versions after an `exclude-newer` change** ([#17721](astral-sh/uv#17721)) Previously, changing the `exclude-newer` setting would cause package versions to be upgraded, ignoring the lockfile entirely. Now, uv will only change package versions if they are no longer within the `exclude-newer` range. You can restore the previous behavior by using `--upgrade` or `--upgrade-package` to opt-in to package version changes. - **Upgrade `uv format` to Ruff 0.15.0** ([#17838](astral-sh/uv#17838)) `uv format` now uses [Ruff 0.15.0](https://github.com/astral-sh/ruff/releases/tag/0.15.0), which uses the [2026 style guide](https://astral.sh/blog/ruff-v0.15.0#the-ruff-2026-style-guide). See the blog post for details. The formatting of code is likely to change. You can opt out of this behavior by requesting an older Ruff version, e.g., `uv format --version 0.14.14`. - **Update uv crate test features to use `test-` as a prefix** ([#17860](astral-sh/uv#17860)) This change only affects redistributors of uv. The Cargo features used to gate test dependencies, e.g., `pypi`, have been renamed with a `test-` prefix for clarity, e.g., `test-pypi`. ##### Stabilizations - **`uv python upgrade` and `uv python install --upgrade`** ([#17766](astral-sh/uv#17766)) When installing Python versions, an [intermediary directory](https://docs.astral.sh/uv/concepts/python-versions/#minor-version-directories) without the patch version attached will be created, and virtual environments will be transparently upgraded to new patch versions. See the [Python version documentation](https://docs.astral.sh/uv/concepts/python-versions/#upgrading-python-versions) for more details. - **`uv add --bounds` and the `add-bounds` configuration option** ([#17660](astral-sh/uv#17660)) This does not come with any behavior changes. You will no longer see an experimental warning when using `uv add --bounds` or `add-bounds` in configuration. - **`uv workspace list` and `uv workspace dir`** ([#17768](astral-sh/uv#17768)) This does not come with any behavior changes. You will no longer see an experimental warning when using these commands. - **`extra-build-dependencies`** ([#17767](astral-sh/uv#17767)) This does not come with any behavior changes. You will no longer see an experimental warning when using `extra-build-dependencies` in configuration. ##### Enhancements - Improve ABI tag error message phrasing ([#17878](astral-sh/uv#17878)) - Introduce a 10s connect timeout ([#17733](astral-sh/uv#17733)) - Allow using `pyx.dev` as a target in `uv auth` commands despite `PYX_API_URL` differing ([#17856](astral-sh/uv#17856)) ##### Bug fixes - Support all CPython ABI tag suffixes properly ([#17817](astral-sh/uv#17817)) - Add support for detecting PowerShell on Linux and macOS ([#17870](astral-sh/uv#17870)) - Retry timeout errors for streams ([#17875](astral-sh/uv#17875)) ### [`v0.9.30`](https://github.com/astral-sh/uv/releases/tag/0.9.30) [Compare Source](astral-sh/uv@0.9.29...0.9.30) #### Release Notes Released on 2026-02-04. ##### Python - Add CPython 3.14.3 and 3.13.12 ([#17849](astral-sh/uv#17849)) ##### Enhancements - Allow comma-separated values for `--extra` option ([#17525](astral-sh/uv#17525)) - Check all files during a dry-run publish instead of stopping at the first failure ([#17785](astral-sh/uv#17785)) - Clarify `UV_HTTP_TIMEOUT` error message ([#17493](astral-sh/uv#17493)) ##### Preview features - Use relocatable virtual environments by default ([#17770](astral-sh/uv#17770)) ##### Bug fixes - Fix deadlock on token refresh in `uv publish` when using pyx ([#17832](astral-sh/uv#17832)) - Ignore global Python pins when incompatible with project ([#15473](astral-sh/uv#15473)) #### Install uv 0.9.30 #####
