[Compare Source](https://togithub.com/bazelbuild/rules_python/compare/0.34.0...0.35.0)
[0.35.0]: https://togithub.com/bazelbuild/rules_python/releases/tag/0.35.0
##### 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](https://togithub.com/bazelbuild/rules_python/issues/2060)).
##### 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](https://togithub.com/bazelbuild/rules_python/issues/2043))
- (rules) Fixes Python builds when the `--build_python_zip` is set to `false` on
Windows. See [#1840](https://togithub.com/bazelbuild/rules_python/issues/1840).
- (rules) Fixes Mac + `--build_python_zip` + {obj}`--bootstrap_impl=script`
([#2030](https://togithub.com/bazelbuild/rules_python/issues/2030)).
- (rules) User dependencies come before runtime site-packages when using
{obj}`--bootstrap_impl=script`.
([#2064](https://togithub.com/bazelbuild/rules_python/issues/2064)).
- (rules) Version-aware rules now return both `@_builtins` and `@rules_python`
providers instead of only one.
([#2114](https://togithub.com/bazelbuild/rules_python/issues/2114)).
- (pip) Fixed pypi parse_simpleapi_html function for feeds with package metadata
containing ">" sign
- (toolchains) Added missing executable permission to
`//python/runtime_env_toolchains` interpreter script so that it is runnable.
([#2085](https://togithub.com/bazelbuild/rules_python/issues/2085)).
- (pip) Correctly use the `sdist` downloaded by the bazel downloader when using
`experimental_index_url` feature. Fixes
[#2091](https://togithub.com/bazelbuild/rules_python/issues/2090).
- (gazelle) Make `gazelle_python_manifest.update` manual to avoid unnecessary
network behavior.
- (bzlmod): The conflicting toolchains during `python` extension will no longer
cause warnings by default. In order to see the warnings for diagnostic purposes
set the env var `RULES_PYTHON_REPO_DEBUG_VERBOSITY` to one of `INFO`, `DEBUG` or `TRACE`.
Fixes [#1818](https://togithub.com/bazelbuild/rules_python/issues/1818).
- (runfiles) Make runfiles lookups work for the situation of Bazel 7,
Python 3.9 (or earlier, where safepath isn't present), and the Rlocation call
in the same directory as the main file.
Fixes [#1631](https://togithub.com/bazelbuild/rules_python/issues/1631).
##### Added
- (rules) `compile_pip_requirements` supports multiple requirements input files as `srcs`.
- (rules) `PYTHONSAFEPATH` is inherited from the calling environment to allow
disabling it (Requires {obj}`--bootstrap_impl=script`)
([#2060](https://togithub.com/bazelbuild/rules_python/issues/2060)).
- (gazelle) Added `python_generation_mode_per_package_require_test_entry_point`
in order to better accommodate users who use a custom macro,
[`pytest-bazel`][pytest_bazel], [rules_python_pytest] or `rules_py`
[py_test_main] in order to integrate with `pytest`. Currently the default
flag value is set to `true` for backwards compatible behaviour, but in the
future the flag will be flipped be `false` by default.
- (toolchains) New Python versions available: `3.12.4` using the [20240726] release.
- (pypi) Support env markers in requirements files. Note, that this means that
if your requirements files contain env markers, the Python interpreter will
need to be run during bzlmod phase to evaluate them. This may incur
downloading an interpreter (for hermetic-based builds) or cause non-hermetic
behavior (if using a system Python).

### [`v0.34.0`](https://togithub.com/bazelbuild/rules_python/blob/HEAD/CHANGELOG.md#0340---2024-07-04)
[Compare Source](https://togithub.com/bazelbuild/rules_python/compare/0.33.2...0.34.0)
[0.34.0]: https://togithub.com/bazelbuild/rules_python/releases/tag/0.34.0
##### Changed
- `protobuf`/`com_google_protobuf` dependency bumped to `v24.4`
- (bzlmod): optimize the creation of config settings used in pip to
reduce the total number of targets in the hub repo.
- (toolchains) The exec tools toolchain now finds its interpreter by reusing
the regular interpreter toolchain. This avoids having to duplicate specifying
where the runtime for the exec tools toolchain is.
- (toolchains) ({obj}`//python:autodetecting_toolchain`) is deprecated. It is
replaced by {obj}`//python/runtime_env_toolchains:all`. The old target will be
removed in a future release.
##### Fixed
- (bzlmod): When using `experimental_index_url` the `all_requirements`,
`all_whl_requirements` and `all_data_requirements` will now only include
common packages that are available on all target platforms. This is to ensure
that packages that are only present for some platforms are pulled only via
the `deps` of the materialized `py_library`. If you would like to include
platform specific packages, using a `select` statement with references to the
specific package will still work (e.g.
my_attr = all_requirements + select(
{
"@platforms//os:linux": ["@pypi//foo_available_only_on_linux"],
"//conditions:default": [],
}
)
- (bzlmod): Targets in `all_requirements` now use the same form as targets returned by the `requirement` macro.
- (rules) Auto exec groups are enabled. This allows actions run by the rules,
such as precompiling, to pick an execution platform separately from what
other toolchains support.
- (providers) {obj}`PyRuntimeInfo` doesn't require passing the
`interpreter_version_info` arg.
- (bzlmod) Correctly pass `isolated`, `quiet` and `timeout` values to `whl_library`
and drop the defaults from the lock file.
- (whl_library) Correctly handle arch-specific dependencies when we encounter a
platform specific wheel and use `experimental_target_platforms`.
Fixes [#1996](https://togithub.com/bazelbuild/rules_python/issues/1996).
- (rules) The first element of the default outputs is now the executable again.
- (pip) Fixed crash when pypi packages lacked a sha (e.g. yanked packages)
##### Added
- (toolchains) {obj}`//python/runtime_env_toolchains:all`, which is a drop-in
replacement for the "autodetecting" toolchain.
- (gazelle) Added new `python_label_convention` and `python_label_normalization` directives. These directive
allows altering default Gazelle label format to third-party dependencies useful for re-using Gazelle plugin
with other rules, including `rules_pycross`. See [#1939](https://togithub.com/bazelbuild/rules_python/issues/1939).
##### Removed
- (pip): Removes the `entrypoint` macro that was replaced by `py_console_script_binary` in 0.26.0.
### [`v0.33.2`](https://togithub.com/bazelbuild/rules_python/blob/HEAD/CHANGELOG.md#0332---2024-06-13)
[Compare Source](https://togithub.com/bazelbuild/rules_python/compare/0.33.1...0.33.2)
[0.33.2]: https://togithub.com/bazelbuild/rules_python/releases/tag/0.33.2
##### Fixed
- (toolchains) The {obj}`exec_tools_toolchain_type` is disabled by default.
To enable it, set {obj}`--//python/config_settings:exec_tools_toolchain=enabled`.
This toolchain must be enabled for precompilation to work. This toolchain will
be enabled by default in a future release.
Fixes [#1967](https://togithub.com/bazelbuild/rules_python/issues/1967).
### [`v0.33.1`](https://togithub.com/bazelbuild/rules_python/blob/HEAD/CHANGELOG.md#0331---2024-06-13)
[Compare Source](https://togithub.com/bazelbuild/rules_python/compare/0.33.0...0.33.1)
[0.33.1]: https://togithub.com/bazelbuild/rules_python/releases/tag/0.33.1
##### Fixed
- (py_binary) Fix building of zip file when using `--build_python_zip`
argument. Fixes [#1954](https://togithub.com/bazelbuild/rules_python/issues/1954).
### [`v0.33.0`](https://togithub.com/bazelbuild/rules_python/blob/HEAD/CHANGELOG.md#0330---2024-06-12)
[Compare Source](https://togithub.com/bazelbuild/rules_python/compare/0.32.2...0.33.0)
[0.33.0]: https://togithub.com/bazelbuild/rules_python/releases/tag/0.33.0
##### Changed
- (deps) Upgrade the `pip_install` dependencies to pick up a new version of pip.
- (toolchains) Optional toolchain dependency: `py_binary`, `py_test`, and
`py_library` now depend on the `//python:exec_tools_toolchain_type` for build
tools.
- (deps): Bumped `bazel_skylib` to 1.6.1.
- (bzlmod): The `python` and internal `rules_python` extensions have been
marked as `reproducible` and will not include any lock file entries from now
on.
- (gazelle): Remove gazelle plugin's python deps and make it hermetic.
Introduced a new Go-based helper leveraging tree-sitter for syntax analysis.
Implemented the use of `pypi/stdlib-list` for standard library module verification.
- (pip.parse): Do not ignore yanked packages when using `experimental_index_url`.
This is to mimic what `uv` is doing. We will print a warning instead.
- (pip.parse): Add references to all supported wheels when using `experimental_index_url`
to allowing to correctly fetch the wheels for the right platform. See the
updated docs on how to use the feature. This is work towards addressing
[#735](https://togithub.com/bazelbuild/rules_python/issues/735) and
[#260](https://togithub.com/bazelbuild/rules_python/issues/260). The spoke
repository names when using this flag will have a structure of
`{pip_hub_prefix}_{wheel_name}_{py_tag}_{abi_tag}_{platform_tag}_{sha256}`,
which is an implementation detail which should not be relied on and is there
purely for better debugging experience.
- (bzlmod) The `pythons_hub//:interpreters.bzl` no longer has platform-specific
labels which where left there for compatibility reasons. Move to
`python_{version}_host` keys if you would like to have access to a Python
interpreter that can be used in a repository rule context.
##### Fixed
- (gazelle) Remove `visibility` from `NonEmptyAttr`.
Now empty(have no `deps/main/srcs/imports` attr) `py_library/test/binary` rules will
be automatically deleted correctly. For example, if `python_generation_mode`
is set to package, when `__init__.py` is deleted, the `py_library` generated
for this package before will be deleted automatically.
- (whl_library): Use `is_python_config_setting` to correctly handle multi-python
version dependency select statements when the `experimental_target_platforms`
includes the Python ABI. The default python version case within the select is
also now handled correctly, stabilizing the implementation.
- (gazelle) Fix Gazelle failing on Windows with
"panic: runtime error: invalid memory address or nil pointer dereference"
- (bzlmod) remove `pip.parse(annotations)` attribute as it is unused and has been
replaced by whl_modifications.
- (pip) Correctly select wheels when the python tag includes minor versions.
See ([#1930](https://togithub.com/bazelbuild/rules_python/issues/1930))
- (pip.parse): The lock file is now reproducible on any host platform if the
`experimental_index_url` is not used by any of the modules in the dependency
chain. To make the lock file identical on each `os` and `arch`, please use
the `experimental_index_url` feature which will fetch metadata from PyPI or a
different private index and write the contents to the lock file. Fixes
[#1643](https://togithub.com/bazelbuild/rules_python/issues/1643).
- (pip.parse): Install `yanked` packages and print a warning instead of
ignoring them. This better matches the behaviour of `uv pip install`.
- (toolchains): Now matching of the default hermetic toolchain is more robust
and explicit and should fix rare edge-cases where the host toolchain
autodetection would match a different toolchain than expected. This may yield
to toolchain selection failures when the python toolchain is not registered,
but is requested via `//python/config_settings:python_version` flag setting.
- (doc) Fix the `WORKSPACE` requirement vendoring example. Fixes
[#1918](https://togithub.com/bazelbuild/rules_python/issues/1918).
##### Added
- (rules) Precompiling Python source at build time is available. but is
disabled by default, for now. Set
`@rules_python//python/config_settings:precompile=enabled` to enable it
by default. A subsequent release will enable it by default. See the
[Precompiling docs][precompile-docs] and API reference docs for more
information on precompiling. Note this requires Bazel 7+ and the Pystar rule
implementation enabled.
([#1761](https://togithub.com/bazelbuild/rules_python/issues/1761))
- (rules) Attributes and flags to control precompile behavior: `precompile`,
`precompile_optimize_level`, `precompile_source_retention`,
`precompile_invalidation_mode`, and `pyc_collection`
- (toolchains) The target runtime toolchain (`//python:toolchain_type`) has
two new optional attributes: `pyc_tag` (tells the pyc filename infix to use) and
`implementation_name` (tells the Python implementation name).
- (toolchains) A toolchain type for build tools has been added:
`//python:exec_tools_toolchain_type`.
- (providers) `PyInfo` has two new attributes: `direct_pyc_files` and
`transitive_pyc_files`, which tell the pyc files a target makes available
directly and transitively, respectively.
- `//python:features.bzl` added to allow easy feature-detection in the future.
- (pip) Allow specifying the requirements by (os, arch) and add extra
validations when parsing the inputs. This is a non-breaking change for most
users unless they have been passing multiple `requirements_*` files together
with `extra_pip_args = ["--platform=manylinux_2_4_x86_64"]`, that was an
invalid usage previously but we were not failing the build. From now on this
is explicitly disallowed.
- (toolchains) Added riscv64 platform definition for python toolchains.
- (gazelle) The `python_visibility` directive now supports the `$python_root$`
placeholder, just like the `python_default_visibility` directive does.
- (rules) A new bootstrap implementation that doesn't require a system Python
is available. It can be enabled by setting
{obj}`--@rules_python//python/config_settings:bootstrap_impl=script`. It
will become the default in a subsequent release.
([#691](https://togithub.com/bazelbuild/rules_python/issues/691))
- (providers) `PyRuntimeInfo` has two new attributes:
{obj}`PyRuntimeInfo.stage2_bootstrap_template` and
{obj}`PyRuntimeInfo.zip_main_template`.
- (toolchains) A replacement for the Bazel-builtn autodetecting toolchain is
available. The `//python:autodetecting_toolchain` alias now uses it.
- (pip): Support fetching and using the wheels for other platforms. This
supports customizing whether the linux wheels are pulled for `musl` or
`glibc`, whether `universal2` or arch-specific MacOS wheels are preferred and
it also allows to select a particular `libc` version. All of this is done via
the `string_flags` in `@rules_python//python/config_settings`. If there are
no wheels that are supported for the target platform, `rules_python` will
fallback onto building the `sdist` from source. This behaviour can be
disabled if desired using one of the available string flags as well.
- (whl_filegroup) Added a new `whl_filegroup` rule to extract files from a wheel file.
This is useful to extract headers for use in a `cc_library`.

Fixes [#1954](https://togithub.com/bazelbuild/rules_python/issues/1954). ### [`v0.33.0`](https://togithub.com/bazelbuild/rules_python/blob/HEAD/CHANGELOG.md#0330---2024-06-12) [Compare Source](https://togithub.com/bazelbuild/rules_python/compare/0.32.2...0.33.0) [0.33.0]: https://togithub.com/bazelbuild/rules_python/releases/tag/0.33.0 ##### Changed - (deps) Upgrade the `pip_install` dependencies to pick up a new version of pip. - (toolchains) Optional toolchain dependency: `py_binary`, `py_test`, and `py_library` now depend on the `//python:exec_tools_toolchain_type` for build tools. - (deps): Bumped `bazel_skylib` to 1.6.1. - (bzlmod): The `python` and internal `rules_python` extensions have been marked as `reproducible` and will not include any lock file entries from now on. - (gazelle): Remove gazelle plugin's python deps and make it hermetic. Introduced a new Go-based helper leveraging tree-sitter for syntax analysis. Implemented the use of `pypi/stdlib-list` for standard library module verification. - (pip.parse): Do not ignore yanked packages when using `experimental_index_url`. This is to mimic what `uv` is doing. We will print a warning instead. - (pip.parse): Add references to all supported wheels when using `experimental_index_url` to allowing to correctly fetch the wheels for the right platform. See the updated docs on how to use the feature. This is work towards addressing [#735](https://togithub.com/bazelbuild/rules_python/issues/735) and [#260](https://togithub.com/bazelbuild/rules_python/issues/260). The spoke repository names when using this flag will have a structure of `{pip_hub_prefix}_{wheel_name}_{py_tag}_{abi_tag}_{platform_tag}_{sha256}`, which is an implementation detail which should not be relied on and is there purely for better debugging experience. - (bzlmod) The `pythons_hub//:interpreters.bzl` no longer has platform-specific labels which where left there for compatibility reasons. Move to `python_{version}_host` keys if you would like to have access to a Python interpreter that can be used in a repository rule context. ##### Fixed - (gazelle) Remove `visibility` from `NonEmptyAttr`. Now empty(have no `deps/main/srcs/imports` attr) `py_library/test/binary` rules will be automatically deleted correctly. For example, if `python_generation_mode` is set to package, when `__init__.py` is deleted, the `py_library` generated for this package before will be deleted automatically. - (whl_library): Use `is_python_config_setting` to correctly handle multi-python version dependency select statements when the `experimental_target_platforms` includes the Python ABI. The default python version case within the select is also now handled correctly, stabilizing the implementation. - (gazelle) Fix Gazelle failing on Windows with "panic: runtime error: invalid memory address or nil pointer dereference" - (bzlmod) remove `pip.parse(annotations)` attribute as it is unused and has been replaced by whl_modifications. - (pip) Correctly select wheels when the python tag includes minor versions. See ([#1930](https://togithub.com/bazelbuild/rules_python/issues/1930)) - (pip.parse): The lock file is now reproducible on any host platform if the `experimental_index_url` is not used by any of the modules in the dependency chain. To make the lock file identical on each `os` and `arch`, please use the `experimental_index_url` feature which will fetch metadata from PyPI or a different private index and write the contents to the lock file. Fixes [#1643](https://togithub.com/bazelbuild/rules_python/issues/1643). - (pip.parse): Install `yanked` packages and print a warning instead of ignoring them. This better matches the behaviour of `uv pip install`. - (toolchains): Now matching of the default hermetic toolchain is more robust and explicit and should fix rare edge-cases where the host toolchain autodetection would match a different toolchain than expected. This may yield to toolchain selection failures when the python toolchain is not registered, but is requested via `//python/config_settings:python_version` flag setting. - (doc) Fix the `WORKSPACE` requirement vendoring example. Fixes [#1918](https://togithub.com/bazelbuild/rules_python/issues/1918). ##### Added - (rules) Precompiling Python source at build time is available. but is disabled by default, for now. Set `@rules_python//python/config_settings:precompile=enabled` to enable it by default. A subsequent release will enable it by default. See the [Precompiling docs][precompile-docs] and API reference docs for more information on precompiling. Note this requires Bazel 7+ and the Pystar rule implementation enabled. ([#1761](https://togithub.com/bazelbuild/rules_python/issues/1761)) - (rules) Attributes and flags to control precompile behavior: `precompile`, `precompile_optimize_level`, `precompile_source_retention`, `precompile_invalidation_mode`, and `pyc_collection` - (toolchains) The target runtime toolchain (`//python:toolchain_type`) has two new optional attributes: `pyc_tag` (tells the pyc filename infix to use) and `implementation_name` (tells the Python implementation name). - (toolchains) A toolchain type for build tools has been added: `//python:exec_tools_toolchain_type`. - (providers) `PyInfo` has two new attributes: `direct_pyc_files` and `transitive_pyc_files`, which tell the pyc files a target makes available directly and transitively, respectively. - `//python:features.bzl` added to allow easy feature-detection in the future. - (pip) Allow specifying the requirements by (os, arch) and add extra validations when parsing the inputs. This is a non-breaking change for most users unless they have been passing multiple `requirements_*` files together with `extra_pip_args = ["--platform=manylinux_2_4_x86_64"]`, that was an invalid usage previously but we were not failing the build. From now on this is explicitly disallowed. - (toolchains) Added riscv64 platform definition for python toolchains. - (gazelle) The `python_visibility` directive now supports the `$python_root$` placeholder, just like the `python_default_visibility` directive does. - (rules) A new bootstrap implementation that doesn't require a system Python is available. It can be enabled by setting {obj}`--@rules_python//python/config_settings:bootstrap_impl=script`. It will become the default in a subsequent release. ([#691](https://togithub.com/bazelbuild/rules_python/issues/691)) - (providers) `PyRuntimeInfo` has two new attributes: {obj}`PyRuntimeInfo.stage2_bootstrap_template` and {obj}`PyRuntimeInfo.zip_main_template`. - (toolchains) A replacement for the Bazel-builtn autodetecting toolchain is available. The `//python:autodetecting_toolchain` alias now uses it. - (pip): Support fetching and using the wheels for other platforms. This supports customizing whether the linux wheels are pulled for `musl` or `glibc`, whether `universal2` or arch-specific MacOS wheels are preferred and it also allows to select a particular `libc` version. All of this is done via the `string_flags` in `@rules_python//python/config_settings`. If there are no wheels that are supported for the target platform, `rules_python` will fallback onto building the `sdist` from source. This behaviour can be disabled if desired using one of the available string flags as well. - (whl_filegroup) Added a new `whl_filegroup` rule to extract files from a wheel file. This is useful to extract headers for use in a `cc_library`. [precompile-docs]: /precompilingConfiguration
