v1.9.0

{#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.
