bazel-contrib/rules_python (rules_python)

v1.9.0

Compare Source

{#v1-9-0-removed}

Removed

• Nothing removed.

{#v1-9-0-changed}

Changed

• DEPRECATED: implicit zipapp support
  • Implicit zipapp output of py_binary/py_test has been deprecated and
    replaced by separate {obj}py_zipapp_binary and {obj}py_zipapp_test
    rules. See
    #​3567
    for a detailed migration guide.
• (toolchains) stop exposing config settings in python toolchain alias repos.
  Please consider depending on the flags defined in
  //python/config_setting/... and the @platforms package instead.
• (binaries/tests) The PYTHONBREAKPOINT environment variable is automatically inherited
• (binaries/tests) The {obj}stamp attribute now transitions the Bazel builtin
  {flag}--stamp flag.
• (pypi) Now the RECORD file patches will follow the quoted or unquoted filenames convention
  in order to make pytorch and friends easier to patch.
• (wheel) py_wheel no longer expands the input depset during analysis,
  improving analysis performance for targets with large dependency trees.
• (binaries/tests) (Windows) --enable_runfiles=true is the default for
  py_binary/py_test. Prior behavior can be restored by adding
  @rules_python//command_line_option:enable_runfiles=false or
  @rules_python//command_line_option:enable_runfiles=INHERIT to the
  config_settings attribute. NOTE: enable_runfiles=true will
  soon become required for Windows.

{#v1-9-0-fixed}

Fixed

• (tests) No more coverage warnings are being printed if there are no sources.
  (#​2762)
• (gazelle) Ancestor conftest.py files are added in addition to sibling conftest.py.
  (#​3497) Note
  that this behavior can be reverted to the pre-1.9.0 behavior by setting the new
  python_include_ancestor_conftest directive to false.
• (binaries/tests) Stamped build data generated by Windows actions is readable

{#v1-9-0-added}

Added

• (binaries/tests) {obj}--debugger: allows specifying an extra dependency
  to add to binaries/tests for custom debuggers.
• (binaries/tests) Build information is now included in binaries and tests.
  Use the bazel_binary_info module to access it. The {flag}--stamp flag will
  add {obj}--workspace_status_command information.
• (gazelle) A new directive python_generate_pyi_srcs has been added. When
  true, a py_* target's pyi_srcs attribute will be set if any .pyi files
  that are associated with the target's srcs are present.
  (#​3354).
• (zipapp) {obj}py_zipapp_binary and {obj}py_zipapp_test rules added. These
  will replace --build_python_zip and the zip output group of
  py_binary/py_test. The zipapp rules support more functionality, correctness,
  and have better build performance.
• (toolchains) Added {obj}PyExecToolsInfo.exec_runtime for more easily
  getting an RBE-compatible runtime to use for build actions.
• (providers) {obj}PyExecutableInfo has several new fields to aid packaging
  of binaries: {obj}PyExecutableInfo.app_runfiles,
  {obj}PyExecutableInfo.interpreter_args,
  {obj}PyExecutableInfo.stage2_bootstrap, and
  {obj}PyExecutableInfo.venv_python_exe.
• (tools/wheelmaker.py) Added support for URL requirements according to PEP 508
  in Requires-Dist metadata. (#​3569)
• (gazelle) A new directive python_include_ancestor_conftest has been added.
  When false, ancestor conftest targets are not automatically added to
  {bzl:obj}py_test target dependencies. This false behavior is how things
  were in rules_python before 1.9.0. The default is true, as the prior behavior
  was technically incorrect.
  (#​3596)

{#v1-8-5}

v1.8.5

Compare Source

{#v1-8-5-fixed}

Fixed

• (runfiles) Fixed CurrentRepository() raising ValueError on Windows.
  (#​3579)
• (pypi) pip_parse no longer silently drops PEP 508 URL-based requirements
  (pkg @​ https://...) when extract_url_srcs=False (the default for
  pip_repository).
• (pypi) Extras in requirement strings are now normalized per PEP 685,
  fixing missing transitive dependencies when extras contain hyphens
  (e.g., sqlalchemy[postgresql-psycopg2binary]).
  (#​3587)

{#v1-8-4}

v1.8.4

Compare Source

{#v1-8-4-fixed}

Fixed

• (pipstar): A corner case of evaluation of version specifiers ("1.2" ~= "1.2.0")
  has been fixed improving compatibility with the PEP440 standard.
  Fixes #​3580.
• (pipstar): We now add read permissions after extracting wheels for the cases
  where the whl file is missing them.
  Fixes #​3554.

{#v1-8-3}

v1.8.3

Compare Source

{#v1-8-3-fixed}

Fixed

• (pipstar) Fix whl extraction on Windows when bazelrc has XX flags.
  Fixes #​3543.

{#v1-8-2}

v1.8.2

Compare Source

{#v1-8-2-fixed}

Fixed

• (venvs) relax the C library filename check to make tensorflow work
  Fixes #​3524.

{#v1-8-1}

v1.8.1

Compare Source

{#v1-8-1-fixed}

Fixed

• (pipstar) Extra resolution that refers back to the package being resolved works again.
  Fixes #​3524.

{#v1-8-0}

v1.8.0

Compare Source

{#v1-8-0-known-issues}

Known Issues

• (gazelle) Windows support for the Gazelle plugin may be broken. See
  #​3416 for
  details and possible workarounds.

{#v1-8-0-removed}

Removed

• (toolchain) Remove all of the python 3.8 toolchain support out of the box. Users need
  to pass the TOOL_VERSIONS that include 3.8 toolchains or use the bzlmod APIs to add
  them back. This means any hub pip.parse calls that target 3.8 will be ignored from
  now on. (#​2704)
  {bzl:obj}python.single_version_override, like:

  python = use_extension("@​rules_python//python/extensions:python.bzl", "python")

  )

• (toolchain) Remove all of the python 3.9 toolchain versions except for the 3.9.25.
  This version has reached EOL and will no longer receive any security fixes, please update to
  3.10 or above. (#​2704)

• (toolchain) ignore_root_user_error has now been flipped to be always enabled and
  the chmod of the python toolchain directories have been removed. From now on rules_python
  always adds the pyc files to the glob excludes and in order to avoid any problems when using
  the toolchains in the repository phase, ensure that you pass -B to the python interpreter.
  (#​2016)

{#v1-8-0-changed}

Changed

• (toolchains) Use toolchains from the 20251031 release.
• (gazelle) Internally split modules mapping generation to be per-wheel for concurrency and caching.
• (pip) pipstar has been enabled for all whl_library instances where the whl
  is passed through a label or downloaded using the bazel downloader
  (#​2949).
• (pypi) pipstar flag default has been flipped to be on by default.
  It can be disabled through RULES_PYTHON_ENABLE_PIPSTAR=0 environment variable.
  If you do need to disable it, please add a comment to
  #​2949.
• (gazelle deps) rules_go bumped from 0.55.1 to 0.59.0
• (gazelle deps) gazelle bumped from 0.36.0 to 0.47.0

{#v1-8-0-fixed}

Fixed

• (gazelle) Remove {obj}py_binary targets with invalid srcs. This includes files
  that are not generated or regular files.
  #​3046
• (runfiles) Fix incorrect Python runfiles path assumption - the existing
  implementation assumes that it is always four levels below the runfiles
  directory, leading to incorrect path checks
  (#​3085).
• (toolchains) local toolchains now tell the sys.abiflags value of the
  underlying runtime.
• (toolchains) various local toolchain fixes: add abi3 header targets,
  fixes to linking, Windows DLL detection, and defines for free threaded
  runtimes.
• (toolchains) The python_headers target is now compatible with
  layering_check.
• (performance) 90% reduction in py_binary/py_test analysis phase cost.
  (#​3381).
• (gazelle) Fix gazelle_python_manifest.test so that it accesses manifest files via runfile path handling rather than directly (#​3397).
• (core rules) For the system_python bootstrap, the runfiles root is added to
  sys.path.
• (sphinxdocs) The sphinxdocs .serve target is now compatible with Bazel's --symlink_prefix
  flag (#​3410).

{#v1-8-0-added}

Added

• (toolchains) 3.9.25 Python toolchain from 20251031 release.
• (toolchains) 3.13.10, 3.14.1 Python toolchain from 20251202 release.
• (toolchains) 3.13.11, 3.14.2, 3.15.0a2 Python toolchains from 20251209 release.
• (pypi) API to tell pip.parse which platforms users care about. This is very useful to ensure
  that when users do bazel query for their deps, they don't have to download all of the
  dependencies for all of the available wheels. Torch wheels can be up of 1GB and it takes a lot
  of time to download those, which is unnecessary if only the host platform builds are necessary
  to be performed. This is mainly for backwards/forwards compatibility whilst rolling out
  RULES_PYTHON_ENABLE_PIPSTAR=1 by default. Users of experimental_index_url that perform
  cross-builds should add {obj}target_platforms to their pip.parse invocations, which will
  become mandatory if any cross-builds are required from the next release.
• (py_library) Attribute {obj}namespace_package_files added. It is a hint for
  optimizing venv creation.

{#v1-7-0}

v1.7.0

Compare Source

{#v1-7-0-removed}

Removed

• (core rules) Support for Bazel's long deprecated "extra actions" has been
  removed
  (#​3215).

{#v1-7-0-changed}

Changed

• (deps) bumped rules_cc dependency to 0.1.5.
• (bootstrap) For {obj}--bootstrap_impl=system_python, PYTHONPATH is no
  longer used to add import paths. The sys.path order has changed from
  [app paths, stdlib, runtime site-packages] to [stdlib, app paths, runtime site-packages].
• (bootstrap) For {obj}--bootstrap_impl=system_python, the sys.path order has
  changed from [app paths, stdlib, runtime site-packages] to [stdlib, app paths, runtime site-packages].
• (pip) Publishing deps are no longer pulled via experimental_index_url.
  (#​2937).
• (toolchains) py_runtime and PyRuntimeInfo reject Python 2 settings.
  Setting py_runtime.python_version = "PY2" or non-None
  PyRuntimeInfo.py2_runtime is an error.
• (pypi) pipstar flag has been implemented for WORKSPACE and can be flipped to be enabled using RULES_PYTHON_ENABLE_PIPSTAR=1 environment variable. If you do, please
  add a comment to
  #​2949 if you run into any
  problems.
  With this release we are deprecating {obj}pip.parse.experimental_target_platforms and
  pip_repository.experimental_target_platforms. For users using WORKSPACE and
  vendoring the requirements.bzl file, please re-vendor so that downstream is unaffected
  when the APIs get removed. If you need to customize the way the dependencies get
  evaluated, see our docs on customizing Requires-Dist resolution.
• (toolchains) Added Python versions 3.15.0a1, 3.14.0, 3.13.9, 3.12.12, 3.11.14, 3.10.19, and 3.9.24
  from the 20251014 release.
• (deps) (bzlmod) Upgraded to bazel-skylib version
  1.8.2

{#v1-7-0-fixed}

Fixed

• (rules) The PyInfo constructor was setting the wrong value for
  has_py3_only_sources - this is now fixed.
• (bootstrap) The stage1 bootstrap script now correctly handles nested RUNFILES_DIR
  environments, fixing issues where a py_binary calls another py_binary
  (#​3187).
• (bootstrap) For Windows, having many dependencies no longer results in max
  length errors due to too long environment variables.
• (bootstrap) {obj}--bootstrap_impl=script now supports the -S interpreter
  setting.
• (venvs) {obj}--venvs_site_packages=yes no longer errors when packages with
  overlapping files or directories are used together.
  (#​3204).
• (venvs) {obj}--venvs_site_packages=yes works for packages that dynamically
  link to shared libraries
  (#​3228).
• (venvs) {obj}--venvs_site_packages=yes includes pth files at the root of the
  site-packages folder
  (#​3339).
• (uv) {obj}//python/uv:lock.bzl%lock now works with a local platform
  runtime.
• (pypi) linux_riscv64 is added to the platforms list in _pip_repository_impl,
  which fixes a build issue for tensorflow on riscv64.
• (toolchains) WORKSPACE builds now correctly register musl and freethreaded
  variants. Setting {obj}--py_linux_libc=musl and --py_freethreaded=yes now
  activate them, respectively.
  (#​3262).
• (rules) {obj}py_console_script_binary is now compatible with symbolic macros
  (#​3195).

{#v1-7-0-added}

Added

• (runfiles) The Python runfiles library now supports Bazel's
  --incompatible_compact_repo_mapping_manifest flag.
• (bootstrap) {obj}--bootstrap_impl=system_python now supports the
  {obj}main_module attribute.
• (bootstrap) {obj}--bootstrap_impl=system_python now supports the
  {any}RULES_PYTHON_ADDITIONAL_INTERPRETER_ARGS environment variable.
• (rules) The py_binary, py_test, and py_wheel rules now have a
  {obj}config_settings attribute to control build flags within the build graph.
  Custom settings can be added using {obj}config.add_transition_setting in
  MODULE.bazel files, or {obj}py_repositories(transition_settings=...) in
  WORKSPACE files. See the
  {ref}common-deps-with-multiple-pypi-versions guide on using common
  dependencies with multiple PyPI versions` for an example.
• (toolchains) Stable ABI headers support added. To use, depend on
  {obj}//python/cc:current_py_cc_headers_abi3. This allows Windows builds
  a way to depend on headers without the potentially Python unstable ABI
  objects from the regular {obj}//python/cc:current_py_cc_headers target
  being included.
  • Adds {obj}//python/cc:current_py_cc_headers_abi3,
    {obj}py_cc_toolchain.headers_abi3, and {obj}PyCcToolchainInfo.headers_abi3.
  • {obj}//python:features.bzl%features.headers_abi3 can be used to
    feature-detect the presense of the above.
• (toolchains) Local toolchains can use a label for the interpreter to use.
• (pypi) Support for environment marker handling and experimental_index_url handling for
  Windows ARM64 for Python 3.11 and later
  (#​2276).
