Fix panic on malformed Python sysconfig prefixes by konstin · Pull Request #22036 · astral-sh/uv

konstin · 2026-09-28T08:34:00Z

Relocate /install only when it is a complete path prefix. A value such as /installé previously caused a UTF-8 boundary panic, and similarly named paths such as /installation were incorrectly rewritten.

This PR contains the following updates: | Package | Type | Update | Change | |---|---|---|---| | [uv](https://github.com/astral-sh/uv) | tools | minor | `0.12.19` → `0.13.0` | --- ### Release Notes <details> <summary>astral-sh/uv (uv)</summary> ### [`v0.13.0`](https://github.com/astral-sh/uv/blob/HEAD/CHANGELOG.md#0130) [Compare Source](https://github.com/astral-sh/uv/compare/0.12.24...0.13.0) Released on 2026-10-09. uv 0.13.0 makes Python 3.15 the default stable Python version. We've also included several breaking changes to improve correctness, performance, and compatibility, described below. **We expect most users to be able to upgrade without making changes.** While not a breaking change, this release also updates the format of many of uv's cache entries to improve performance. **uv may download or rebuild dependencies after upgrading**, because some cached entries from earlier versions cannot be reused. Multiple versions of uv can still safely share the same cache directory. There are no breaking changes to the configuration of the [uv build backend](https://docs.astral.sh/uv/concepts/build-backend/). If your `[build-system]` table includes an upper bound on `uv_build`, update it to allow `uv_build` 0.13, e.g., `uv_build>=0.13.0,<0.14`. ##### Breaking changes - **Use Python 3.15 as the default stable version** The default stable Python version has changed from 3.14 to 3.15. This affects Python downloads when no version is requested or pinned, e.g., when running `uv python install`. uv continues to use compatible Python installations that are already present. For example, `uv venv` can still use an installed Python 3.14. If no suitable interpreter is installed and automatic downloads are enabled, commands such as `uv venv` and `uvx python` can now download Python 3.15. You can opt out of this behavior by requesting Python 3.14 explicitly, e.g., `uv venv --python 3.14`. For projects, use `uv python pin 3.14` to record the version in `.python-version`. - **Honor `--require-hashes` in included constraints files** ([#22275](https://github.com/astral-sh/uv/pull/22275)) Previously, uv ignored `--require-hashes` in constraints files included with `-c` from a requirements file. Now, uv honors the directive and requires hashes for all requirements in the installation. Installs that previously succeeded can now fail if a requirement is missing a hash. You cannot opt out while the directive is present. Add the missing hashes to your requirements, or remove the `--require-hashes` directive from the included constraints file if hash checking is not intended. - **Prefer native Python on Windows ARM64** ([#22100](https://github.com/astral-sh/uv/pull/22100)) Previously, ARM64 builds of uv preferred emulated `x86_64` Python installations because native wheel support was limited. Now, uv prefers native ARM64 (`aarch64`) interpreters across Python versions. This follows similar changes in [CPython](https://discuss.python.org/t/python-on-windows-arm64/104524), the official Windows [Python install manager](https://discuss.python.org/t/python-install-manager-26-4/108846), and GitHub's [actions/setup-python](https://github.com/actions/setup-python#supported-architectures). When a native interpreter is unavailable, uv continues to fall back to `x86_64`, then 32-bit `x86`. You can opt out of this behavior by setting `UV_PYTHON_ARCH=x86_64` or requesting an explicit architecture, e.g., `cpython-3.14-windows-x86_64`. If you are using `setup-uv`, you can set [`python-arch: x86_64`](https://github.com/astral-sh/setup-uv#python-architecture) instead. - **Reject editable requirements in included constraints files** ([#22282](https://github.com/astral-sh/uv/pull/22282)) Previously, uv silently ignored editable (`-e`) requirements in constraints files included with `-c` from a requirements file. Now, uv rejects these requirements with an error, matching [pip's behavior](https://pip.pypa.io/en/stable/user_guide/#constraints-files). You cannot opt out of this behavior. Move editable requirements to a requirements file passed with `-r`, or pass them directly with `--editable`, instead of including them in a constraints file. - **Omit the distutils startup patch on Python 3.10 and later** ([#22096](https://github.com/astral-sh/uv/pull/22096)) Previously, uv installed `_virtualenv.py` and `_virtualenv.pth` into every new virtual environment to prevent distutils configuration from changing installation paths. Now, like [`virtualenv` 21.6.0](https://github.com/pypa/virtualenv/releases/tag/21.6.0), uv omits these files on Python 3.10 and later, which already ignore the affected configuration keys. This reduces Python startup overhead. Python 3.9 and earlier retain the patch. You cannot opt out of this behavior. Existing virtual environments are not modified automatically. Recreate an environment with Python 3.10 or later to remove the patch. This stabilizes the `no-distutils-patch` preview feature. - **Treat requirement-file option values as single paths** ([#22290](https://github.com/astral-sh/uv/pull/22290)) Previously, uv split values passed to `--constraint`, `--override`, `--exclude`, and `--build-constraint` on spaces, even when quoted. Now, each value is treated as a single path, allowing file paths containing spaces. You cannot opt out of this behavior. Repeat the option to provide multiple files. For example, replace `-c "a.txt b.txt"` with `-c a.txt -c b.txt`. Space-separated lists in `UV_CONSTRAINT`, `UV_OVERRIDE`, `UV_EXCLUDE`, and `UV_BUILD_CONSTRAINT` remain supported. - **Use `tar-codec` for tar archives by default** ([#22094](https://github.com/astral-sh/uv/pull/22094)) Previously, uv used `astral-tokio-tar` to extract tar archives, build source distributions with `uv_build`, and read their metadata for `uv publish`. Now, uv uses `tar-codec`, which applies stricter validation when reading archives. uv may now reject archives containing hard links or unsupported tar extensions that previous versions accepted. Source distributions created by `uv_build` can also have different archive bytes and hashes. You can opt out of this behavior by setting `UV_LEGACY_TAR_BACKEND=1`. This stabilizes the `tar-codec` preview feature. - **Reject `uv build --clear` output directories that contain a build source** ([#22276](https://github.com/astral-sh/uv/pull/22276)) Previously, `uv build --clear` could delete a project or input source distribution when the output directory contained the source. Now, uv rejects these output directories, including equivalent paths reached through symlinks, before clearing any build output. Select an output directory that does not contain any build sources, or omit `--clear`. ##### Python - Add CPython 3.15.0 ([#22400](https://github.com/astral-sh/uv/pull/22400)) ##### Preview features -

have attestations generated with GitHub Artifact Attestations. These can be verified by using the [GitHub CLI](https://cli.github.com/manual/gh_attestation_verify): ```sh gh attestation verify <file-path of downloaded artifact> --repo astral-sh/uv ``` You can also download the attestation from [GitHub](https://github.com/astral-sh/uv/attestations) and verify against that directly: ```sh gh attestation verify <file-path of downloaded artifact> --bundle <file-path of downloaded attestation> ``` ### [`v0.12.20`](https://github.com/astral-sh/uv/releases/tag/0.12.20) [Compare Source](https://github.com/astral-sh/uv/compare/0.12.19...0.12.20) #### Release Notes Released on 2026-09-28. ##### Enhancements - Reuse lockfiles when dependency declarations are semantically equivalent ([#21951](https://github.com/astral-sh/uv/pull/21951)) - Preserve second-line encoding declarations when installing wheel scripts with CRLF shebangs ([#21990](https://github.com/astral-sh/uv/pull/21990)) ##### Preview features - Write normalized requirement declarations with the `lockfile-normalization` preview feature ([#21951](https://github.com/astral-sh/uv/pull/21951)) - Honor synthetic default groups when installing or syncing from `pylock.toml` ([#22003](https://github.com/astral-sh/uv/pull/22003)) - Resolve local paths in exported `pylock.toml` files relative to the output file ([#22042](https://github.com/astral-sh/uv/pull/22042)) - Install each package only once when repeated `tool-install-locks` requirements resolve to the same package ([#22000](https://github.com/astral-sh/uv/pull/22000)) - Reuse `lock-without-metadata` lockfiles for conflicting groups with distinct base and extra requirement specifiers ([#22055](https://github.com/astral-sh/uv/pull/22055)) - Use consistent root-package paths in `uv workspace metadata` and `uv tree --format json` output ([#22050](https://github.com/astral-sh/uv/pull/22050)) ##### Configuration - Continue searching `XDG_CONFIG_DIRS` after empty entries ([#21987](https://github.com/astral-sh/uv/pull/21987)) ##### Performance - Restore the previous HTTP cache-write scheduling while investigating severe cache-revalidation stalls on ext4 filesystems ([#22051](https://github.com/astral-sh/uv/pull/22051)) ##### Bug fixes - Apply hash constraints to every repeated requirement under `--require-hashes` and `--verify-hashes` ([#21996](https://github.com/astral-sh/uv/pull/21996)) - Allow metadata builds for first-party workspace projects under `--no-build` ([#21988](https://github.com/astral-sh/uv/pull/21988)) - Honor project exclusion flags with `--all-packages`, including `--no-install-project` and `--no-emit-project` ([#21994](https://github.com/astral-sh/uv/pull/21994)) - Restore `pyproject.toml` if `uv upgrade` fails or is interrupted ([#21983](https://github.com/astral-sh/uv/pull/21983)) - Generate working Nushell activation scripts for relocatable virtual environments ([#21979](https://github.com/astral-sh/uv/pull/21979)) - Prevent commands from running and changing state after displaying `--show-settings` ([#21989](https://github.com/astral-sh/uv/pull/21989)) - Treat UTF-16 requirements files containing only a byte-order mark as empty ([#21991](https://github.com/astral-sh/uv/pull/21991)) - Ignore unrecognized managed-Python implementation directories during `uv python list` and `uv python upgrade` instead of panicking ([#22033](https://github.com/astral-sh/uv/pull/22033)) - Avoid panics and incorrect rewriting when managed Python sysconfig paths merely start with `/install` ([#22036](https://github.com/astral-sh/uv/pull/22036)) - Report whitespace-only non-ASCII requirements as invalid instead of panicking ([#22035](https://github.com/astral-sh/uv/pull/22035)) - Avoid a resolver panic when trace logging an always-false constraint ([#22034](https://github.com/astral-sh/uv/pull/22034)) #### Install uv 0.12.20 ##### Install prebuilt binaries via shell script ```sh curl --proto '=https' --tlsv1.2 -LsSf https://releases.astral.sh/github/uv/releases/download/0.12.20/uv-installer.sh | sh ``` #####
