Reproducible uv build backend across operating systems #13171

konstin · 2025-04-28T08:46:21Z

The goal of this PR is to support reproducible builds and best-effort platform-independent builds. Previously, while the build backend would build the same source dist and wheel on the same machine, they would look different across different operating systems. This PR fixes the platform-dependent walk dir order by sorting and removes platform-specific permissions from the source dist that had caused those differences.

The reproducibility goal does not extend to platform-dependent filesystem features, such as permissions and links, especially in interaction with Git. Since most users share code across platforms through Git, we're focusing on cross-platform behavior under Git. One of those caveats is intentional: If a file, such as a bash script, has an executable bit, we preserve it. This means that E.g. builds of Git checkout of a repository with an executable shell script in the sources will have different archives on Unix and Windows. Another relevant case are symlinks: By default, Git on Windows replaces symlinks with a file that contains the path to the target file (https://stackoverflow.com/q/5917249/3549270). (This example comes from Cargo, where it means that the package archive is different on Windows when symlinking license from the repository root to a workspace package)

We want to ensure that the uv build backend source dists and wheels are the same across machines, so we check that the hash of the resulting wheel is constant between developer machines and Windows/Linux/macOS CI.

Now that the walk dir order is deterministic, the snapshot doesn't need sorting anymore.

Makes sense to me! Thanks for the commit-by-commit PR. :-)

We expect most users to be able to upgrade without making changes. ##### Breaking changes - **Update `uv version` to display and update project versions ([#12349](astral-sh/uv#12349 Previously, `uv version` displayed uv's version. Now, `uv version` will display or update the project's version. This interface was [heavily requested](astral-sh/uv#6298) and, after much consideration, we decided that transitioning the top-level command was the best option. Here's a brief example: ```console $ uv init example Initialized project `example` at `./example` $ cd example $ uv version example 0.1.0 $ uv version --bump major example 0.1.0 => 1.0.0 $ uv version --short 1.0.0 ``` If used outside of a project, uv will fallback to showing its own version still: ```console $ uv version warning: failed to read project: No `pyproject.toml` found in current directory or any parent directory running `uv self version` for compatibility with old `uv version` command. this fallback will be removed soon, pass `--preview` to make this an error. uv 0.7.0 (4433f41c9 2025-04-29) ``` As described in the warning, `--preview` can be used to error instead: ```console $ uv version --preview error: No `pyproject.toml` found in current directory or any parent directory ``` The previous functionality of `uv version` was moved to `uv self version`. - **Avoid fallback to subsequent indexes on authentication failure ([#12805](astral-sh/uv#12805 When using the `first-index` strategy (the default), uv will stop searching indexes for a package once it is found on a single index. Previously, uv considered a package as "missing" from an index during authentication failures, such as an HTTP 401 or HTTP 403 (normally, missing packages are represented by an HTTP 404). This behavior was motivated by unusual responses from some package indexes, but reduces the safety of uv's index strategy when authentication fails. Now, uv will consider an authentication failure as a stop-point when searching for a package across indexes. The `index.ignore-error-codes` option can be used to recover the existing behavior, e.g.: ```toml [[tool.uv.index]] name = "pytorch" url = "https://download.pytorch.org/whl/cpu" ignore-error-codes = [401, 403] ``` Since PyTorch's indexes always return a HTTP 403 for missing packages, uv special-cases indexes on the `pytorch.org` domain to ignore that error code by default. - **Require the command in `uvx <name>` to be available in the Python environment ([#11603](astral-sh/uv#11603 Previously, `uvx` would attempt to execute a command even if it was not provided by a Python package. For example, if we presume `foo` is an empty Python package which provides no command, `uvx foo` would invoke the `foo` command on the `PATH` (if present). Now, uv will error early if the `foo` executable is not provided by the requested Python package. This check is not enforced when `--from` is used, so patterns like `uvx --from foo bash -c "..."` are still valid. uv also still allows `uvx foo` where the `foo` executable is provided by a dependency of `foo` instead of `foo` itself, as this is fairly common for packages which depend on a dedicated package for their command-line interface. - **Use index URL instead of package URL for keyring credential lookups ([#12651](astral-sh/uv#12651 When determining credentials for querying a package URL, uv previously sent the full URL to the `keyring` command. However, some keyring plugins expect to receive the *index URL* (which is usually a parent of the package URL). Now, uv requests credentials for the index URL instead. This behavior matches `pip`. - **Remove `--version` from subcommands ([#13108](astral-sh/uv#13108 Previously, uv allowed the `--version` flag on arbitrary subcommands, e.g., `uv run --version`. However, the `--version` flag is useful for other operations since uv is a package manager. Consequently, we've removed the `--version` flag from subcommands — it is only available as `uv --version`. - **Omit Python 3.7 downloads from managed versions ([#13022](astral-sh/uv#13022 Python 3.7 is EOL and not formally supported by uv; however, Python 3.7 was previously available for download on a subset of platforms. - **Reject non-PEP 751 TOML files in install, compile, and export commands ([#13120](astral-sh/uv#13120), [#13119](astral-sh/uv#13119 Previously, uv treated arbitrary `.toml` files passed to commands (e.g., `uv pip install -r foo.toml` or `uv pip compile -o foo.toml`) as `requirements.txt`-formatted files. Now, uv will error instead. If using PEP 751 lockfiles, use the standardized format for custom names instead, e.g., `pylock.foo.toml`. - **Ignore arbitrary Python requests in version files ([#12909](astral-sh/uv#12909 uv allows arbitrary strings to be used for Python version requests, in which they are treated as an executable name to search for in the `PATH`. However, using this form of request in `.python-version` files is non-standard and conflicts with `pyenv-virtualenv` which writes environment names to `.python-version` files. In this release, uv will now ignore requests that are arbitrary strings when found in `.python-version` files. - **Error on unknown dependency object specifiers ([12811](astral-sh/uv#12811 The `[dependency-groups]` entries can include "object specifiers", e.g. `set-phasers-to = ...` in: ```toml [dependency-groups] foo = ["pyparsing"] bar = [{set-phasers-to = "stun"}] ``` However, the only current spec-compliant object specifier is `include-group`. Previously, uv would ignore unknown object specifiers. Now, uv will error. - **Make `--frozen` and `--no-sources` conflicting options ([#12671](astral-sh/uv#12671 Using `--no-sources` always requires a new resolution and `--frozen` will always fail when used with it. Now, this conflict is encoded in the CLI options for clarity. - **Treat empty `UV_PYTHON_INSTALL_DIR` and `UV_TOOL_DIR` as unset ([#12907](astral-sh/uv#12907), [#12905](astral-sh/uv#12905 Previously, these variables were treated as set to the current working directory when set to an empty string. Now, uv will ignore these variables when empty. This matches uv's behavior for other environment variables which configure directories. ##### Enhancements - Disallow mixing requirements across PyTorch indexes ([#13179](astral-sh/uv#13179)) - Add optional managed Python archive download cache ([#12175](astral-sh/uv#12175)) - Add `poetry-core` as a `uv init` build backend option ([#12781](astral-sh/uv#12781)) - Show tag hints when failing to

Test build backend reproducibility across machines

519c464

We want to ensure that the uv build backend source dists and wheels are the same across machines, so we check that the hash of the resulting wheel is constant between developer machines and Windows/Linux/macOS CI.

Sort walkdir by name for determinism
