rules_python Changelog

This is a human-friendly changelog in a keepachangelog.com style format. Because this changelog is for end-user consumption of meaningful changes,only a summary of a release‘s changes is described. This means every commit is not necessarily mentioned, and internal refactors or code cleanups are omitted unless they’re particularly notable.

A brief description of the categories of changes:

  • Changed: Some behavior changed. If the change is expected to break a public API or supported behavior, it will be marked as BREAKING. Note that beta APIs will not have breaking API changes called out.
  • Fixed: A bug, or otherwise incorrect behavior, was fixed.
  • Added: A new feature, API, or behavior was added in a backwards compatible manner.
  • Particular sub-systems are identified using parentheses, e.g. (bzlmod) or (docs).

Unreleased

Changed

  • Python version patch level bumps:

    • 3.8.15 -> 3.8.17
    • 3.9.17 -> 3.9.18
    • 3.10.12 -> 3.10.13
    • 3.11.4 -> 3.11.5

  • (deps) Upgrade rules_go 0.39.1 -> 0.41.0; this is so gazelle integration works with upcoming Bazel versions

  • (multi-version) The distribs attribute is no longer propagated. This attribute has been long deprecated by Bazel and shouldn't be used.

  • Calling //python:repositories.bzl#py_repositories() is required. It has always been documented as necessary, but it was possible to omit it in certain cases. An error about @rules_python_internal means the py_repositories() call is missing in WORKSPACE.

  • (bzlmod) The pip.parse extension will generate os/arch specific lock file entries on bazel>=6.4.

Added

  • (bzlmod, entry_point) Added py_console_script_binary, which allows adding custom dependencies to a package's entry points and customizing the py_binary rule used to build it.
  • New Python versions available: 3.8.17, 3.9.18, 3.10.13, 3.11.5 using https://github.com/indygreg/python-build-standalone/releases/tag/20230826.
  • (gazelle) New # gazelle:python_generation_mode file directive to support generating one py_library per file.
  • (python_repository) Support netrc and auth_patterns attributes to enable authentication against private HTTP hosts serving Python toolchain binaries.
  • //python:packaging_bzl added, a bzl_library for the Starlark files //python:packaging.bzl requires.

Removed

  • (bzlmod) The entry_point macro is no longer supported and has been removed in favour of the py_console_script_binary macro for bzlmod users.

  • (bzlmod) The pip.parse no longer generates {hub_name}_{py_version} hub repos as the entry_point macro has been superseded by py_console_script_binary.

  • (bzlmod) The pip.parse no longer generates {hub_name}_{distribution} hub repos.

Fixed

  • (whl_library) No longer restarts repository rule when fetching external dependencies improving initial build times involving external dependency fetching.

  • (gazelle) Improve runfiles lookup hermeticity.

0.25.0 - 2023-08-22

Changed

  • Python version patch level bumps:
    • 3.9.16 -> 3.9.17
    • 3.10.9 -> 3.10.12
    • 3.11.1 -> 3.11.4
  • (bzlmod) pip.parse can no longer automatically use the default Python version; this was an unreliable and unsafe behavior. The python_version arg must always be explicitly specified.

Fixed

  • (docs) Update docs to use correct bzlmod APIs and clarify how and when to use various APIs.
  • (multi-version) The main arg is now correctly computed and usually optional.
  • (bzlmod) pip.parse no longer requires a call for whatever the configured default Python version is.

Added

  • Created a changelog.
  • (gazelle) Stop generating unnecessary imports.
  • (toolchains) s390x supported for Python 3.9.17, 3.10.12, and 3.11.4.

0.24.0 - 2023-07-11

  • (bzlmod) pip.parse arg incompatible_generate_aliases removed and always true.

Fixed

  • (bzlmod) Fixing Windows Python Interpreter symlink issues
  • (py_wheel) Allow twine tags and args
  • (toolchain, bzlmod) Restrict coverage tool visibility under bzlmod
