Release Notes

bazelbuild/rules_python (rules_python)

v0.27.0

Compare Source

Changed

• Make //python/pip_install:pip_repository_bzl bzl_library target internal
  as all of the publicly available symbols (etc. package_annotation) are
  re-exported via //python:pip_bzl bzl_library.

• (gazelle) Gazelle Python extension no longer has runtime dependencies. Using
  GAZELLE_PYTHON_RUNTIME_DEPS from @rules_python_gazelle_plugin//:def.bzl is
  no longer necessary.

• (pip_parse) The installation of pip_parse repository rule toolchain
  dependencies is now done as part of py_repositories call.

• (pip_parse) The generated requirements.bzl file now has an additional symbol
  all_whl_requirements_by_package which provides a map from the normalized
  PyPI package name to the target that provides the built wheel file. Use
  pip_utils.normalize_name function from @rules_python//python:pip.bzl to
  convert a PyPI package name to a key in the all_whl_requirements_by_package
  map.

• (pip_parse) The flag incompatible_generate_aliases has been flipped to
  True by default on non-bzlmod setups allowing users to use the same label
  strings during the transition period. For example, instead of
  @pypi_foo//:pkg, you can now use @pypi//foo or @pypi//foo:pkg. Other
  labels that are present in the foo package are dist_info, whl and
  data. Note, that the @pypi_foo//:pkg labels are still present for
  backwards compatibility.

• (gazelle) The flag use_pip_repository_aliases is now set to True by
  default, which will cause gazelle to change third-party dependency labels
  from @pip_foo//:pkg to @pip//foo by default.

• The compile_pip_requirements now defaults to pyproject.toml if the src
  or requirements_in attributes are unspecified, matching the upstream
  pip-compile behaviour more closely.

• (gazelle) Use relative paths if possible for dependencies added through
  the use of the resolve directive.

• (gazelle) When using python_generation_mode file, one py_test target is
  made per test file even if a target named __test__ or a file named
  __test__.py exists in the same package. Previously in these cases there
  would only be one test target made.

Breaking changes:

• (pip) pip_install repository rule in this release has been disabled and
  will fail by default. The API symbol is going to be removed in the next
  version, please migrate to pip_parse as a replacement. The pip_parse
  rule no longer supports requirements attribute, please use
  requirements_lock instead.

• (py_wheel) switch incompatible_normalize_name and
  incompatible_normalize_version to True by default to enforce PEP440
  for wheel names built by rules_python.

• (tools/wheelmaker.py) drop support for Python 2 as only Python 3 is tested.

Fixed

• Skip aliases for unloaded toolchains. Some Python versions that don't have full
  platform support, and referencing their undefined repositories can break operations
  like bazel query rdeps(...).

• Python code generated from proto_library with strip_import_prefix can be imported now.

• (py_wheel) Produce deterministic wheel files and make RECORD file entries
  follow the order of files written to the .whl archive.

• (gazelle) Generate a single py_test target when gazelle:python_generation_mode project
  is used.

• (gazelle) Move waiting for the Python interpreter process to exit to the shutdown hook
  to make the usage of the exec.Command more idiomatic.

• (toolchains) Keep tcl subdirectory in Windows build of hermetic interpreter.

• (bzlmod) sub-modules now don't have the //conditions:default clause in the
  hub repos created by pip.parse. This should fix confusing error messages
  in case there is a misconfiguration of toolchains or a bug in rules_python.

Added

• (bzlmod) Added .whl patching support via patches and patch_strip
  arguments to the new pip.override tag class.

• (pip) Support for using PEP621 compliant
  pyproject.toml for creating a resolved requirements.txt file.

• (utils) Added a pip_utils struct with a normalize_name function to allow users
  to find out how rules_python would normalize a PyPI distribution name.
