fix(deps): Update dependency rules_python to v1 #84

(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)
{object}python.single_version_override, like:

python = use_extension("@&#8203;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.

(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
{obj}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).

(pypi) We now use the Minimal Version Selection (MVS) algorithm to select
the right wheel when there are multiple wheels for the target platform
(e.g. musllinux_1_1_x86_64 and musllinux_1_2_x86_64). If the user
wants to set the minimum version for the selection algorithm, use the
{attr}pip.defaults.whl_platform_tags attribute to configure that. If
musllinux_*_x86_64 is specified, we will choose the lowest available
wheel version. Fixes #3250.

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

(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.

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.

(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.

(deps) platforms 0.0.4 -> 0.0.11
(py_wheel) Package py_library.pyi_srcs (.pyi files) in the wheel.
(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 {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>).

(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
