{#v1-6-0-changed}

Changed

• (gazelle) update minimum gazelle version to 0.36.0 - may cause BUILD file changes
• (gazelle) update minimum rules_go version to 0.55.1
• (gazelle) remove custom go-tree-sitter module BUILD file
• (gazelle) For package mode, resolve dependencies when imports are relative
  to the package path. This is enabled via the
  # gazelle:python_experimental_allow_relative_imports true directive ({gh-issue}2203).
• (gazelle) Types for exposed members of python.ParserOutput are now all public.
• (gazelle) Removed the requirement for __init__.py, __main__.py, or __test__.py files to be
  present in a directory to generate a BUILD.bazel file.
• (toolchain) Updated the following toolchains to build 20250808 to patch CVE-2025-47273:
  • 3.9.23
  • 3.10.18
  • 3.11.13
  • 3.12.11
  • 3.14.0rc1
• (toolchain) Python 3.13 now references 3.13.6
• (gazelle) Switched back to smacker/go-tree-sitter, fixing
  #​2630
• (pypi) From now on the list of default platforms only includes linux_x86_64, linux_aarch64,
  osx_x86_64, osx_aarch64 and windows_x86_64. If you are on other platforms, you need to
  use the pip.default to configure it yourself. If you are interested in graduating the
  platform, consider helping set us up CI for them and update the documentation.
• (ci) We are now testing on Ubuntu 22.04 for RBE and non-RBE configurations.
• (core) #!/usr/bin/env bash is now used as a shebang in the stage1 bootstrap template.
• (gazelle:docs) The Gazelle docs have been migrated from {gh-path}gazelle/README.md to
  {gh-path}gazelle/docs and are now available on the primary documentation site
  at https://rules-python.readthedocs.io/en/latest/gazelle/docs/index.html

{#v1-6-0-fixed}

Fixed

• (toolchains) local_runtime_repo now respects changes to the DEVELOPER_DIR and XCODE_VERSION
  repo env vars, fixing stale cache issues on macOS with system (i.e. Xcode-supplied) Python
  (#​3123).
• (pypi) Fixes an issue where builds using a bazel vendor vendor directory
  would fail if the constraints file contained environment markers. Fixes
  #​2996.
• (pypi) Wheels with BUILD.bazel (or other special Bazel files) no longer
  result in missing files at runtime
  (#​2782).
• (runfiles) The pypi runfiles package now includes py.typed to indicate it
  supports type checking
  (#​2503).
• (pypi) The pipstar defaults configuration now supports any custom platform
  name.
• (pypi) The selection of the whls has been changed and should no longer result
  in ambiguous select matches ({gh-issue}2759) and should be much more efficient
  when running bazel query due to fewer repositories being included
  ({gh-issue}2849).
• Multi-line python imports (e.g. with escaped newlines) are now correctly processed by Gazelle.
• (toolchains) local_runtime_repo works with multiarch Debian with Python 3.8
  (#​3099).
• (pypi) Expose pypi packages only common to all Python versions in all_requirements
  (#​2921).
• (repl) Normalize the path for the REPL stub to make it possible to use the
  default stub template from outside rules_python ({gh-issue}3101).
• (gazelle) Fixes gazelle adding sibling module dependencies to resolve
  absolute imports (Python 2's behavior without absolute_import). Previous
  behavior can be restored using the directive
  # gazelle:python_resolve_sibling_imports true
• (pypi) Show overridden index URL of packages when downloading metadata have failed.
  (#​2985).
• (toolchains) use "command -v" to find interpreter in $PATH
  (#​3150).
• (pypi) bazel vendor now works in bzlmod ({gh-issue}3079).
• (toolchains) local_runtime_repo now works on Windows
  (#​3055).
• (toolchains) local_runtime_repo supports more types of Python
  installations (Mac frameworks, missing dynamic libraries, and other
  esoteric cases, see
  #​3148 for details).
• (pypi) Support requirements.txt files that use different versions of the same
  package targeting different target platforms.
  (#​2797).
• (py_wheel) Add directories in deterministic order.

{#v1-6-0-added}

Added

• (repl) Default stub now has tab completion, where readline support is available,
  see (#​3114).
  (#​3114).
• (pypi) To configure the environment for requirements.txt evaluation, use the newly added
  developer preview of the pip.default tag class. Only rules_python and root modules can use
  this feature. You can also configure custom config_settings using pip.default. It
  can also be used to set the global netrc or auth_patterns variables.
• (pypi) PyPI dependencies now expose an :extracted_whl_files filegroup target
  of all the files extracted from the wheel. This can be used in lieu of
  {obj}whl_filegroup to avoid copying/extracting wheel multiple times to
  get a subset of their files.
• (gazelle) New directive gazelle:python_generate_pyi_deps; when true,
  dependencies added to satisfy type-only imports (if TYPE_CHECKING) and type
  stub packages are added to pyi_deps instead of deps.
• (toolchain) Add toolchains for aarch64 windows for
  • 3.11.13
  • 3.12.11
  • 3.13.6
  • 3.14.0rc1
• (gazelle): New annotation gazelle:include_pytest_conftest. When not set (the
  default) or true, gazelle will inject any conftest.py file found in the same
  directory as a {obj}py_test target to that {obj}py_test target's deps.
  This behavior is unchanged from previous versions. When false, the :conftest
  dep is not added to the {obj}py_test target.
• (gazelle) New directive gazelle:python_generate_proto; when true,
  Gazelle generates py_proto_library rules for proto_library. false by default.
  • Note: Users must manually configure their Gazelle target to support the
    proto language.
• (gazelle) New directive gazelle:python_proto_naming_convention; controls
  naming of py_proto_library rules.

{#v1-5-0-fixed}

Fixed

• (rules) PyInfo provider is now advertised by py_test, py_binary, and py_library;
  this allows aspects using required_providers to function correctly.
  (#​2506).
• Fixes when using {obj}--bootstrap_impl=script:

  multiple times.
• (tools/wheelmaker.py) Extras are now preserved in Requires-Dist metadata when using requires_file
  to specify the requirements.
• (pypi) Use bazel downloader for direct URL references and correctly detect the filenames from

{#v1-4-0-changed}

Changed

• (toolchain) The exec configuration toolchain now has the forwarded
  exec_interpreter now also forwards the ToolchainInfo provider. This is
  for increased compatibility with the RBE setups where access to the exec
  configuration interpreter is needed.
• (toolchains) Use the latest astral-sh toolchain release 20250317 for Python versions:
  • 3.9.21
  • 3.10.16
  • 3.11.11
  • 3.12.9
  • 3.13.2
• (pypi) Use xcrun xcodebuild --showsdks to find XCode root.
• (toolchains) Remove all but 3.8.20 versions of the Python 3.8 interpreter who has
  reached EOL. If users still need other versions of the 3.8 interpreter, please supply
  the URLs manually {bzl:obj}python.toolchain or {bzl:obj}python_register_toolchains calls.
• (toolchains) Previously #​2636
  changed the semantics of ignore_root_user_error from "ignore" to "warning". This is now
  flipped back to ignoring the issue, and will only emit a warning when the attribute is set
  False.
• (pypi) The PyPI extension will no longer write the lock file entries as the
  extension has been marked reproducible.
  Fixes #​2434.
• (gazelle) Lazily load and parse manifest files when running Gazelle. This ensures no
  manifest files are loaded when Gazelle is run over a set of non-python directories
  PR #​2746.
• (rules) {attr}py_binary.srcs and {attr}py_test.srcs is no longer mandatory when
  main_module is specified (for --bootstrap_impl=script)

{#v1-4-0-fixed}

Fixed

• (pypi) Platform specific extras are now correctly handled when using
  universal lock files with environment markers. Fixes #​2690.
• (runfiles) ({obj}--bootstrap_impl=script) Follow symlinks when searching for runfiles.
• (toolchains) Do not try to run chmod when downloading non-windows hermetic toolchain
  repositories on Windows. Fixes
  #​2660.
• (logging) Allow repo rule logging level to be set to FAIL via the RULES_PYTHON_REPO_DEBUG_VERBOSITY environment variable.
• (toolchains) The toolchain matching is has been fixed when writing
  transitions transitioning on the python_version flag.
  Fixes #​2685.
• (toolchains) Run the check on the Python interpreter in isolated mode, to ensure it's not affected by userland environment variables, such as PYTHONPATH.
• (toolchains) Ensure temporary .pyc and .pyo files are also excluded from the interpreters repository files.
• (pypi) Run interpreter version call in isolated mode, to ensure it's not affected by userland environment variables, such as PYTHONPATH.
• (packaging) An empty requires_file is treated as if it were omitted, resulting in a valid METADATA file.
• (rules) py_wheel and sphinxdocs rules now propagate target_compatible_with to all targets they create.
  PR #​2788.
• (pypi) Correctly handle METADATA entries when python_full_version is used in
  the environment marker.
  Fixes #​2319.
• (pypi) Correctly handle python_version parameter and transition the requirement
  locking to the right interpreter version when using
  {obj}compile_pip_requirements rule.
  See #​2819.

{#v1-4-0-added}

Added

• (pypi) From now on sha256 values in the requirements.txt is no longer
  mandatory when enabling {attr}pip.parse.experimental_index_url feature.
  This means that rules_python will attempt to fetch metadata for all
  packages through SimpleAPI unless they are pulled through direct URL
  references. Fixes #​2023.
  In case you see issues with rules_python being too eager to fetch the SimpleAPI
  metadata, you can use the newly added {attr}pip.parse.simpleapi_skip
  to skip metadata fetching for those packages.
• (uv) A {obj}lock rule that is the replacement for the
  {obj}compile_pip_requirements. This may still have rough corners
  so please report issues with it in the
  #​1975.
  Main highlights - the locking can be done within a build action or outside
  it, there is no more automatic test target (but it can be added on the user
  side by using native_test). For customizing the uv version that is used,
  please check the {obj}uv.configure tag class.
• Add support for riscv64 linux platform.
• (toolchains) Add python 3.13.2 and 3.12.9 toolchains
• (providers) (experimental) PyInfo.site_packages_symlinks field added to
  allow specifying links to create within the venv site packages (only
  applicable with {obj}--bootstrap_impl=script)
  (#​2156).
• (toolchains) Local Python installs can be used to create a toolchain
  equivalent to the standard toolchains. See [Local toolchains] docs for how to
  configure them.
• (toolchains) Expose $(PYTHON2_ROOTPATH) and $(PYTHON3_ROOTPATH) which are runfiles
  locations equivalents of $(PYTHON2) and `$(PYTHON3) respectively.

• (py_package) Package py_library.pyi_srcs (.pyi files) in py_package.
• (gazelle) The generated manifest file (default: gazelle_python.yaml) will now include the
  YAML document start --- line. Implemented in
  #​2656.

{#v1-3-0-fixed}

Fixed

• (pypi) The ppc64le is now pointing to the right target in the platforms package.
• (gazelle) No longer incorrectly merge py_binary targets during partial updates in
  file generation mode. Fixed in #​2619.
• (bzlmod) Running as root is no longer an error. ignore_root_user_error=True
  is now the default. Note that running as root may still cause spurious
  Bazel cache invalidation
  (#​1169).
• (gazelle) Don't collapse depsets to a list or into args when generating the modules mapping file.
  Support spilling modules mapping args into a params file.
• (coverage) Fix missing files in the coverage report if they have no tests.
• (pypi) From now on python invocations in repository and module extension
  evaluation contexts will invoke Python interpreter with -B to avoid
  creating .pyc files.
• (deps) doublestar 4.7.1 (required for recent Gazelle versions)

{#v1-3-0-added}

Added

• (python) {obj}python.defaults has been added to allow users to
  set the default python version in the root module by reading the
  default version number from a file or an environment variable.
• {obj}//python/bin:python: convenience target for directly running an
  interpreter. {obj}--//python/bin:python_src can be used to specify a
  binary whose interpreter to use.
• (uv) Now the extension can be fully configured via bzlmod APIs without the
  need to patch rules_python. The documentation has been added to rules_python
  docs but usage of the extension may result in your setup breaking without any
  notice. What is more, the URLs and SHA256 values will be retrieved from the
  GitHub releases page metadata published by the uv project.
• (pypi) An extra argument to add the interpreter lib dir to LDFLAGS when
  building wheels from sdist.
• (pypi) Direct HTTP urls for wheels and sdists are now supported when using
  {obj}experimental_index_url (bazel downloader).
  Partially fixes #​2363.
• (rules) APIs for creating custom rules based on the core py_binary, py_test,
  and py_library rules
  (#​1647)
• (rules) Added env-var to allow additional interpreter args for stage1 bootstrap.
  See {any}RULES_PYTHON_ADDITIONAL_INTERPRETER_ARGS environment variable.
  Only applicable for {obj}--bootstrap_impl=script.
• (rules) Added {obj}interpreter_args attribute to py_binary and py_test,
  which allows pass arguments to the interpreter before the regular args.
• (rules) Added {obj}main_module attribute to py_binary and py_test,
  which allows specifying a module name to run (i.e. python -m <module>).

v1.1.0

Compare Source

{#v1-1-0-changed}

Changed

• (toolchains) 3.13 means 3.13.1 (previously 3.13.0)
• Bazel 6 support is dropped and Bazel 7.4.1 is the minimum supported
  version, per our Bazel support matrix. Earlier versions are not
  tested by CI, so functionality cannot be guaranteed.
• ({bzl:obj}pip.parse) From now we will make fewer calls to indexes when
  fetching the metadata from SimpleAPI. The calls will be done in parallel to
  each index separately, so the extension evaluation time might slow down if
  not using {bzl:obj}pip.parse.experimental_index_url_overrides.
• ({bzl:obj}pip.parse) Only query SimpleAPI for packages that have
  sha values in the requirements.txt file.
• (rules) The version-aware rules have been folded into the base rules and
  the version-aware rules are now simply aliases for the base rules. The
  python_version attribute is still used to specify the Python version.
• (pypi) Updated versions of packages: pip to 24.3.1 and
  packaging to 24.2.

{#v1-1-0-deprecations}

Deprecations

• //python/config_settings:transitions.bzl and its py_binary and py_test
  wrappers are deprecated. Use the regular rules instead.

{#v1-1-0-fixed}

Fixed

• (py_wheel) Use the default shell environment when building wheels to allow
  toolchains that search PATH to be used for the wheel builder tool.
• (pypi) The requirement argument parsed to whl_library will now not have env
  marker information allowing bazel query to work in cases where the whl is
  available for all of the platforms and the sdist can be built. This fix is
  for both WORKSPACE and bzlmod setups.
  Fixes #​2450.
• (gazelle) Gazelle will now correctly parse Python3.12 files that use PEP 695 Type
  Parameter Syntax. (#​2396)
• (pypi) Using {bzl:obj}pip_parse.experimental_requirement_cycles and
  {bzl:obj}pip_parse.use_hub_alias_dependencies together now works when
  using WORKSPACE files.
• (pypi) The error messages when the wheel distributions do not match anything
  are now printing more details and include the currently active flag
  values. Fixes #​2466.
• (py_proto_library) Fix import paths in Bazel 8.
• (whl_library) Now the changes to the dependencies are correctly tracked when
  PyPI packages used in whl_library during the repository rule phase
  change. Fixes #​2468.

• (gazelle) Gazelle no longer ignores setup.py files by default. To restore
  this behavior, apply the # gazelle:python_ignore_files setup.py directive.

• Don't re-fetch whl_library, python_repository, etc. repository rules
  whenever PATH changes. Fixes
  #​2551.

{#v1-1-0-added}

Added

• (gazelle) Added include_stub_packages flag to modules_mapping. When set to True, this
  automatically includes corresponding stub packages for third-party libraries
  that are present and used (e.g., boto3 → boto3-stubs), improving
  type-checking support.
• (pypi) Freethreaded packages are now fully supported in the
  {obj}experimental_index_url usage or the regular pip.parse usage.
  To select the free-threaded interpreter in the repo phase, please use
  the documented env variables.
  Fixes #​2386.
• (toolchains) Use the latest astral-sh toolchain release 20241206 for Python versions:
  • 3.9.21
  • 3.10.16
  • 3.11.11
  • 3.12.8
  • 3.13.1
• (rules) Attributes for type definition files (.pyi files) and type-checking
  only dependencies added. See {obj}py_library.pyi_srcs and
  py_library.pyi_deps (and the same named attributes for py_binary and
  py_test).
• (pypi) pypi-generated targets set pyi_srcs to include *.pyi files.
• (providers) {obj}PyInfo has new fields to aid static analysis tools:
  {obj}direct_original_sources, {obj}direct_pyi_files,
  {obj}transitive_original_sources, {obj}transitive_pyi_files.

Breaking:

• (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.
• (toolchains) consumers who were depending on the MACOS_NAME and the arch
  attribute in the PLATFORMS list, please update your code to respect the new
  values. The values now correspond to the values available in the
  @platforms// package constraint values.
• (toolchains) host_platform and interpreter constants are no longer created
  in the toolchain generated alias .bzl files. If you need to access the
  host interpreter during the repository_rule evaluation, please use the
  @python_{version}_host//:python targets created by
  {bzl:obj}python_register_toolchains and
  {bzl:obj}python_register_multi_toolchains macros or the {bzl:obj}python
  bzlmod extension.
• (bzlmod) pip.parse.parse_all_requirements_files attribute has been removed.
  See notes in the previous versions about what to do.
• (deps) rules_cc 0.1.0 (workspace) and 0.0.16 (bzlmod).
• (deps) protobuf 29.0-rc2 (workspace; bzlmod already specifying that version).

Other changes:

• (python_repository) Start honoring the strip_prefix field for zstd archives.
• (pypi) {bzl:obj}pip_parse.extra_hub_aliases now works in WORKSPACE files.
• (binaries/tests) For {obj}--bootstrap_impl=script, a binary-specific (but
  otherwise empty) virtual env is used to customize sys.path initialization.
• (deps) bazel_skylib 1.7.0 (workspace; bzlmod already specifying that version)
• (deps) bazel_features 1.21.0; necessary for compatibility with Bazel 8 rc3
• (deps) stardoc 0.7.2 to support Bazel 8.

{#v1-0-0-fixed}

Fixed

• (toolchains) stop depending on uname to get the value of the host platform.
• (pypi): Correctly handle multiple versions of the same package in the requirements
  files which is useful when including different PyTorch builds (e.g. <pytorch+cpu> vs <pytorch+cu118> ) for different target platforms.
  Fixes (2337).
• (uv): Correct the sha256sum for the uv binary for aarch64-apple-darwin.
  Fixes (2411).
• (binaries/tests) ({obj}--bootstrap_impl=scipt) Using sys.executable will
  use the same sys.path setup as the calling binary.
  (2169).
• (workspace) Corrected protobuf's name to com_google_protobuf, the name is
  hardcoded in Bazel, WORKSPACE mode.
• (pypi): {bzl:obj}compile_pip_requirements no longer fails on Windows when --enable_runfiles is not enabled.
• (pypi): {bzl:obj}compile_pip_requirements now correctly updates files in the source tree on Windows when --windows_enable_symlinks is not enabled.
• (repositories): Add libs/python3.lib and pythonXY.dll to the libpython target
  defined by a repository template. This enables stable ABI builds of Python extensions
  on Windows (by defining Py_LIMITED_API).
• (rules) py_test and py_binary targets no longer incorrectly remove the
  first sys.path entry when using {obj}--bootstrap_impl=script

{#v1-0-0-added}

Added

• (gazelle): Parser failures will now be logged to the terminal. Additional
  details can be logged by setting RULES_PYTHON_GAZELLE_VERBOSE=1.
• (toolchains) allow users to select which variant of the support host toolchain
  they would like to use through
  RULES_PYTHON_REPO_TOOLCHAIN_{VERSION}_{OS}_{ARCH} env variable setting. For
  example, this allows one to use freethreaded python interpreter in the
  repository_rule to build a wheel from sdist.
• (toolchain) The python interpreters targeting muslc libc have been added
  for the latest toolchain versions for each minor Python version. You can control
  the toolchain selection by using the
  {bzl:obj}//python/config_settings:py_linux_libc build flag.
• (providers) Added {obj}PyRuntimeInfo.site_init_template and
  {obj}PyRuntimeInfo.site_init_template for specifying the template to use to
  initialize the interpreter via venv startup hooks.
• (runfiles) (Bazel 7.4+) Added support for spaces and newlines in runfiles paths

{#v1-0-0-removed}

Removed

• (pypi): Remove pypi_install_dependencies macro that has been included in
  {bzl:obj}py_repositories for a long time.
• (bzlmod): Remove DEFAULT_PYTHON_VERSION from interpreters.bzl file. If
  you need the version, please use it from the versions.bzl file instead.

• (publish) Remove deprecated requirements.txt for the twine dependencies.
  Please use requirements_linux.txt instead.
• (python_repository) Use bazel's built in zstd support and remove attributes
  for customizing the zstd binary to be used for zstd archives in the
  {bzl:obj}python_repository repository_rule. This affects the
  {bzl:obj}python_register_toolchains and
  {bzl:obj}python_register_multi_toolchains callers in the WORKSPACE.

{#v0-39-0}

v0.39.0

Compare Source

{#v0-39-0-changed}

Changed

• (deps) bazel_skylib 1.6.1 -> 1.7.1
• (deps) rules_cc 0.0.9 -> 0.0.14
• (deps) protobuf 24.4 -> 29.0-rc2
• (deps) rules_proto 6.0.0-rc1 -> 6.0.2
• (deps) stardoc 0.6.2 -> 0.7.1
• For bzlmod, Bazel 7.4 is now the minimum Bazel version.
• (toolchains) Use the latest indygreg toolchain release 20241016 for Python versions:
  • 3.9.20
  • 3.10.15
  • 3.11.10
  • 3.12.7
  • 3.13.0
• (pypi) The naming scheme for the bzlmod spoke repositories have changed as
  all of the given requirements.txt files are now parsed by default, to
  temporarily restore the behavior, you can use
  {bzl:obj}pip.parse.extra_hub_aliases, which will be removed or made noop in
  the future.

{#v0-39-0-fixed}

Fixed

• (precompiling) Skip precompiling (instead of erroring) if the legacy
  @bazel_tools//tools/python:autodetecting_toolchain is being used
  (#​2364).

{#v0-39-0-added}

Added

• Bazel 8 is now supported.
• (toolchain) Support for freethreaded Python toolchains is now available. Use
  the config flag //python/config_settings:py_freethreaded to toggle the
  selection of the free-threaded toolchains.
• (toolchain) {obj}py_runtime.abi_flags attribute and
  {obj}PyRuntimeInfo.abi_flags field added.

{#v0-39-0-removed}

Removed

• Support for Bazel 6 using bzlmod has been dropped.

{#v0-38-0}

v0.38.0

Compare Source

{#v0-38-0-changed}

Changed

• (deps) (WORKSPACE only) rules_cc 0.0.13 and protobuf 27.0 is now the default
  version used; this for Bazel 8+ support (previously version was rules_cc 0.0.9
  and no protobuf version specified)
  (2310).
• (publish) The dependencies have been updated to the latest available versions
  for the twine publishing rule.
• (whl_library) Remove --no-build-isolation to allow non-hermetic sdist builds
  by default. Users wishing to keep this argument and to enforce more hermetic
  builds can do so by passing the argument in
  pip.parse#extra_pip_args
• (pip.parse) {attr}pip.parse.whl_modifications now normalizes the given whl names
  and now pyyaml and PyYAML will both work.
• (bzlmod) pip.parse spoke repository naming will be changed in an upcoming
  release in places where the users specify different package versions per
  platform in the same hub repository. The naming of the spoke repos is
  considered an implementation detail and we advise the users to use the hub
  repository directly and make use of {bzl:obj}pip.parse.extra_hub_aliases
  feature added in this release.

{#v0-38-0-fixed}

Fixed

• (pypi) (Bazel 7.4+) Allow spaces in filenames included in whl_librarys
  (617).
• (pypi) When {attr}pip.parse.experimental_index_url is set, we need to still
  pass the extra_pip_args value when building an sdist.
• (pypi) The patched wheel filenames from now on are using local version specifiers
  which fixes usage of the said wheels using standard package managers.
• (bzlmod) The extension evaluation has been adjusted to always generate the
  same lock file irrespective if experimental_index_url is set by any module
  or not. To opt into this behavior, set
  pip.parse.parse_all_requirements_files, which will become the
  default in future releases leading up to 1.0.0. Fixes
  #​2268. A known
  issue is that it may break bazel query and in these use cases it is
  advisable to use cquery or switch to download_only = True

{#v0-38-0-added}

Added

• (publish) The requirements file for the twine publishing rules have been
  updated to have a new convention: requirements_darwin.txt,
  requirements_linux.txt, requirements_windows.txt for each respective OS
  and one extra file requirements_universal.txt if you prefer a single file.
  The requirements.txt file may be removed in the future.
• The rules_python version is now reported in //python/features.bzl#features.version
• (pip.parse) {attr}pip.parse.extra_hub_aliases can now be used to expose extra
  targets created by annotations in whl repositories.
  Fixes #​2187.
• (bzlmod) pip.parse now supports whl-only setup using
  download_only = True where users can specify multiple requirements files
  and use the pip backend to do the downloading. This was only available for
  users setting {bzl:obj}pip.parse.experimental_index_url, but now users have
  more options whilst we continue to work on stabilizing the experimental feature.

{#v0-37-2}

v0.37.2

Compare Source

{#v0-37-2-fixed}

Fixed

• (bzlmod) Generate config_setting values for all available toolchains instead
  of only the registered toolchains, which restores the previous behaviour that
  bzlmod users would have observed.

{#v0-37-1}

v0.37.1

Compare Source

{#v0-37-1-fixed}

Fixed

• (rules) Setting --incompatible_python_disallow_native_rules no longer
  causes rules_python rules to fail
  (#​2326).

{#v0-37-0}

v0.37.0

Compare Source

{#v0-37-0-changed}

Changed

• BREAKING py_library no longer puts its source files or generated pyc
  files in runfiles; it's the responsibility of consumers (e.g. binaries) to
  populate runfiles with the necessary files. Adding source files to runfiles
  can be temporarily restored by setting {obj}--add_srcs_to_runfiles=enabled,
  but this flag will be removed in a subsequent releases.
• {obj}PyInfo.transitive_sources is now added to runfiles. These files are
  .py files that are required to be added to runfiles by downstream binaries
  (or equivalent).
• (toolchains) py_runtime.implementation_name now defaults to cpython
  (previously it defaulted to None).
• (toolchains) The exec tools toolchain is enabled by default. It can be
  disabled by setting
  {obj}--@​rules_python//python/config_settings:exec_tools_toolchain=disabled.
• (deps) stardoc 0.6.2 added as dependency.

{#v0-37-0-fixed}

Fixed

• (bzlmod) The python.override(minor_mapping) now merges the default and the
  overridden versions ensuring that the resultant minor_mapping will always
  have all of the python versions.
• (bzlmod) The default value for the {obj}--python_version flag will now be
  always set to the default python toolchain version value.
• (bzlmod) correctly wire the {attr}pip.parse.extra_pip_args all the
  way to whl_library. What is more we will pass the extra_pip_args to
  whl_library for sdist distributions when using
  {attr}pip.parse.experimental_index_url. See
  #​2239.
• (whl_filegroup): Provide per default also the RECORD file
• (py_wheel): RECORD file entry elements are now quoted if necessary when a
  wheel is created
• (whl_library) truncate progress messages from the repo rule to better handle
  case where a requirement has many --hash=sha256:... flags
• (rules) compile_pip_requirements passes env to the X.update target (and
  not only to the X_test target, a bug introduced in
  #​1067).
• (bzlmod) In hybrid bzlmod with WORKSPACE builds,
  python_register_toolchains(register_toolchains=True) is respected
  (#​1675).
• (precompiling) The {obj}pyc_collection attribute now correctly
  enables (or disables) using pyc files from targets transitively
• (pip) Skip patching wheels not matching pip.override's file
  (#​2294).
• (chore): Add a rules_shell dev dependency and moved a sh_test target
  outside of the //:BUILD.bazel file.
  Fixes #​2299.

{#v0-37-0-added}

Added

• (py_wheel) Now supports compress = (True|False) to allow disabling
  compression to speed up development.
• (toolchains): A public //python/config_settings:python_version_major_minor has
  been exposed for users to be able to match on the X.Y version of a Python
  interpreter.
• (api) Added {obj}merge_py_infos() so user rules can merge and propagate
  PyInfo without losing information.
• (toolchains) New Python versions available: 3.13.0 using the 20241008 release.
• (toolchains): Bump default toolchain versions to:
  • 3.8 -> 3.8.20
  • 3.9 -> 3.9.20
  • 3.10 -> 3.10.15
  • 3.11 -> 3.11.10
  • 3.12 -> 3.12.7
• (coverage) Add support for python 3.13 and bump coverage.py to 7.6.1.
• (bzlmod) Add support for download_only flag to disable usage of sdists
  when {bzl:attr}pip.parse.experimental_index_url is set.
• (api) PyInfo fields: {obj}PyInfo.transitive_implicit_pyc_files,
  {obj}PyInfo.transitive_implicit_pyc_source_files.

{#v0-37-0-removed}

Removed

• (precompiling) --precompile_add_to_runfiles has been removed.
• (precompiling) --pyc_collection has been removed. The pyc_collection
  attribute now bases its default on {obj}--precompile.
• (precompiling) The {obj}precompile=if_generated_source value has been removed.
• (precompiling) The {obj}precompile_source_retention=omit_if_generated_source value has been removed.

{#v0-36-0}

v0.36.0

Compare Source

{#v0-36-0-changed}

Changed

• (gazelle): Update error messages when unable to resolve a dependency to be more human-friendly.
• (flags) The {obj}--python_version flag now also returns
  {obj}config_common.FeatureFlagInfo.
• (toolchain): The toolchain patches now expose the patch_strip attribute
  that one should use when patching toolchains. Please set it if you are
  patching python interpreter. In the next release the default will be set to
  0 which better reflects the defaults used in public bazel APIs.
• (toolchains) When {obj}py_runtime.interpreter_version_info isn't specified,
  the {obj}--python_version flag will determine the value. This allows
  specifying the build-time Python version for the
  {obj}runtime_env_toolchains.
• (toolchains) {obj}py_cc_toolchain.libs and {obj}PyCcToolchainInfo.libs is
  optional. This is to support situations where only the Python headers are
  available.
• (bazel) Minimum bazel 7 version that we test against has been bumped to 7.1.

{#v0-36-0-fixed}

Fixed

• (whl_library): Remove --no-index and add --no-build-isolation to the
  pip install command when installing a wheel from a local file, which happens
  when experimental_index_url flag is used.
• (bzlmod) get the path to the host python interpreter in a way that results in
  platform non-dependent hashes in the lock file when the requirement markers need
  to be evaluated.
• (bzlmod) correctly watch sources used for evaluating requirement markers for
  any changes so that the repository rule or module extensions can be
  re-evaluated when the said files change.
• (gazelle): Fix incorrect use of t.Fatal/t.Fatalf in tests.
• (toolchain) Omit third-party python packages from coverage reports from
  stage2 bootstrap template.
• (bzlmod) Properly handle relative path URLs in parse_simpleapi_html.bzl
• (gazelle) Correctly resolve deps that have top-level module overlap with a gazelle_python.yaml dep module
• (rules) Make RUNFILES_MANIFEST_FILE-based invocations work when used with
  {obj}--bootstrap_impl=script. This fixes invocations using non-sandboxed
  test execution with --enable_runfiles=false --build_runfile_manifests=true.
  (#​2186).
• (py_wheel) Fix incorrectly generated Required-Dist when specifying requirements with markers
  in extra_requires in py_wheel rule.
• (rules) Prevent pytest from trying run the generated stage2
  bootstrap .py file when using {obj}--bootstrap_impl=script
• (toolchain) The gen_python_config_settings has been fixed to include
  the flag_values from the platform definitions.

{#v0-36-0-added}

Added

• (bzlmod): Toolchain overrides can now be done using the new
  {bzl:obj}python.override, {bzl:obj}python.single_version_override and
  {bzl:obj}python.single_version_platform_override tag classes.
  See #​2081.
• (rules) Executables provide {obj}PyExecutableInfo, which contains
  executable-specific information useful for packaging an executable or
  or deriving a new one from the original.
• (py_wheel) Removed use of bash to avoid failures on Windows machines which do not
  have it installed.
• (docs) Automatically generated documentation for {bzl:obj}python_register_toolchains
  and related symbols.
• (toolchains) Added {attr}python_repository.patch_strip attribute for
  allowing values that are other than 1, which has been hard-coded up until
  now. If you are relying on the undocumented patches support in
  TOOL_VERSIONS for registering patched toolchains please consider setting
  the patch_strip explicitly to 1 if you depend on this value - in the
  future the value may change to default to 0.
• (toolchains) Added //python:none, a special target for use with
  {obj}py_exec_tools_toolchain.exec_interpreter to treat the value as None.

{#v0-36-0-removed}

Removed

• (toolchains): Removed accidentally exposed http_archive symbol from
  python/repositories.bzl.
• (toolchains): An internal is_python_config_setting macro has been removed.

{#v0-35-0}

v0.35.0

Compare Source

{#v0-35-0-changed}

Changed

• (whl_library) A better log message when the wheel is built from an sdist or
  when the wheel is downloaded using download_only feature to aid debugging.
• (gazelle): Simplify and make gazelle_python.yaml have only top level package name.
  It would work well in cases to reduce merge conflicts.
• (toolchains): Change some old toochain versions to use [20240726] release to
  include dependency updates 3.8.19, 3.9.19, 3.10.14, 3.11.9
• (toolchains): Bump default toolchain versions to:
  • 3.12 -> 3.12.4
• (rules) PYTHONSAFEPATH is inherited from the calling environment to allow
  disabling it (Requires {obj}--bootstrap_impl=script)
  (#​2060).

{#v0-35-0-fixed}

Fixed

• (rules) compile_pip_requirements now sets the USERPROFILE env variable on
  Windows to work around an issue where setuptools fails to locate the user's
  home directory.
• (rules) correctly handle absolute URLs in parse_simpleapi_html.bzl.
• (rules) Fixes build targets linking against @rules_python//python/cc:current_py_cc_libs
  in host platform builds on macOS, by editing the LC_ID_DYLIB field of the hermetic interpreter's
  libpython3.x.dylib using install_name_tool, setting it to its absolute path under Bazel's
  execroot.
• (rules) Signals are properly received when using {obj}--bootstrap_impl=script
  (for non-zip builds).
  (#​2043)
• (rules) Fixes Python builds when the --build_python_zip is set to false on
  Windows. See #​1840.
• (rules) Fixes Mac + --build_python_zip + {obj}
