It is now possible to build Mac wheels on native machines in Github
Actions, so ARM64 Mac wheels are now built and tested on M1 machines.
Also, the artifact up-/download was migrated to v4, which made it
necessary to upload wheels to unique artifact names, and then later
stitch them together again in a subsequent job.
The cross-platform Mac build injection in setup.py was removed,
since it is no longer necessary.
I relanded a monkey-patching of Bazel build files, this time for
MODULE.bazel. This is because `rules_python` does not allow running
as the root user, which is the case in cibuildwheel+Linux (happens
in a Docker container). Since I did not see a quick way of switching
to rootless containers, and did not want to hardcode the config change
(it can apparently cause cache misses and build failures), I inject the
"ignore_root_user_error" flag into the MODULE.bazel file when running
in cibuildwheel on Linux.
This comes following the first BCR release of nanobind_bazel.
Feature-wise, nothing substantial has changed, except that the extensions
are stripped of debug info when built in release mode, which reduces
clutter in the symbol tables.
No stubgen yet, since nanobind v2 has not been released yet.
* Add a bzlmod Python bindings build
Uses the newly started `@nanobind_bazel` project to build nanobind
extensions. This means that we can drop all in-tree custom build defs
and build files for nanobind and the C++ Python headers.
Additionally, the temporary WORKSPACE overwrite hack naturally goes away
due to the WORKSPACE system being obsolete.
* Bump ruff -> v0.3.1, change ruff settings
The latest minor releases incurred some formatting and configuration
changes, this commit rolls them out.

Bumps `rules_foreign_cc` to v0.10.1 (October 2023), `bazel_skylib` to
v1.5.0 (November 2023), `rules_python` to v0.27.1 (December 2023).
Also syncs GoogleTest to v1.12.1 (the last C++11 supporting version) to
be the same as in MODULE.bazel.
Since the latest `rules_python` changed its setup calling convention,
that is updated also in the WORKSPACE file.
* Add pre-commit config and GitHub Actions job
Contains the following hooks:
* buildifier - for formatting and linting Bazel files.
* mypy, ruff, isort, black - for Python typechecking, import hygiene,
static analysis, and formatting.
The pylint CI job was changed to be a pre-commit CI job, where pre-commit
is bootstrapped via Python.
Pylint is currently no longer part of the
code checks, but can be re-added if requested. The reason to drop was
that it does not play nicely with pre-commit, and lots of its
functionality and responsibilities are actually covered in ruff.
* Add dev extra to pyproject.toml for development installs
* Clarify that pre-commit contains only Python and Bazel hooks
* Add one-line docstrings to Bazel modules
* Apply buildifier pre-commit fixes to Bazel files
* Apply pre-commit fixes to Python files
* Supply --profile=black to isort to prevent conflicts
* Fix nanobind build file formatting
* Add tooling configs to `pyproject.toml`
In particular, set line length 80 for all Python files.
* Reformat all Python files to line length 80, fix return type annotations
Also ignores the `tools/compare.py` and `tools/gbench/report.py` files
for mypy, since they emit a barrage of errors which we can deal with
later. The errors are mostly related to dynamic classmethod definition.
* Change nanobind linkage to response file approach
This change needs https://github.com/bazelbuild/bazel/pull/18952 to be
merged first. Fixes macOS linkage of GBM's nanobind bindings on macOS by
supplying a linker response file instead of `-undefined dynamic_lookup`.
The latter has since been deprecated on macOS.
* Fix bazel_skylib checksum, bump skylib version in MODULE.bazel
* Bump Bazel to version 6.4.0 for linker response file support
* Migrate to bzlmod
* Update Python version to PY3, as indicated by the actual source file.
* Migrate more libraries & first draft of direct pywheel rule usage in Bazel
* Integrate with nanobind and libpfm
* Make Python toolchain a dev dependency
* Undo py_wheel usage until later
* Added support for bzlmod for C++ parts of google_benchmark.
* Make //tools:all buildable with --enable_bzlmod
