* Add Python 3.12 support tag
* Bump nanobind to latest stable v1.6.2 tag
* Add PyPI trusted publishing to GitHub workflow, add Python 3.12 wheel builds
Trusted publishing has been available since v1.8.0 of the pypa-publish
action. It enables password-less authentication and wheel uploads from
the wheel upload job.
`cibuildwheel` was bumped to v2.16.2 to allow Python 3.12 wheel builds.
More info on trusted publishing:
https://github.com/marketplace/actions/pypi-publish#trusted-publishing
The Windows distribution was reverted to `latest` in the OS matrix,
since the discovery problem of MSVC was fixed in a Bazel patch release.
* Bump nanobind to stable v1.7.0 tag
Bumps nanobind to v0.2.0, the latest stable version to include all
features needed to create the GBM bindings. Deprecated names in v0.2.0
were migrated to their new counterparts.
Linkopts for macOS were changed to mirror the "endorsed" linker options
used in nanobind's CMake config, which were changed since the last
commit.
* End support for Python 3.7, update cibuildwheel and publish actions
Removes Python 3.7 from the support matrix, since it does not support
PEP590 vectorcalls.
Bumps the `cibuildwheel` and `pypa-publish` actions to their latest
available versions respectively.
* Add nanobind to the Bazel dependencies, add a BUILD file
The build file builds nanobind as a static `cc_library`. Currently,
the git SHA points to HEAD, since some necessary features have not
been included in a release yet.
* Delete pybind11 BUILD file
* Switch bindings implementation to nanobind
Switches over the binding tool to `nanobind` from `pybind11`. Most
changes in the build setup itself were drop-in replacements of existing
code changed to nanobind names, no new concepts needed to be
implemented.
Sets the minimum required macOS to 10.14 for full C++17 support. Also,
to avoid ambiguities in Bazel, build for macOS 11 on Mac ARM64.
* Use Bazel select for linker options
Guards against unknown linker option errors by selecting required
linker options for nanobind only on macOS, where they are relevant.
Other changes:
* Bump cibuildwheel action to v2.12.0
* Bump Bazel for aarch64 linux wheels to 6.0.0
* Remove C++17 flag from build files since it is present in setup.py `bazel build` command
* Bump nanobind commit to current HEAD (TBD: Bump to next stable release)
* Unbreak Windows builds of nanobind-based bindings
Guards compiler options behind a new `select` macro choosing between
MSVC and not MSVC.
Other changes:
* Inject the proper C++17 standard cxxopt in the `setup.py` build
command.
* Bump nanobind to current HEAD.
* Make `macos` a benchmark-wide condition, with public visibility to
allow its use in the nanobind BUILD file.
* Fall back to `nb::implicitly_convertible` for Counter construction
Since `benchmark::Counter` only has a constructor for `double`,
the nanobind `nb::init_implicit` template cannot be used. Therefore,
to support implicit construction from ints, we fall back to the
`nb::implicitly_convertible` template instead.
* Add `benchmark_workspace.bzl` function
This commit adds a `benchmark_workspace.bzl` function to Google
Benchmark. It is intended to be used as a means to pull in Google
Benchmark's build dependencies in its own Bazel workspace, as well
as in workspaces of downstream projects.
* Migrate WORKSPACE to use the newly created benchmark_deps.bzl
This commit changes Google Benchmark's own WORKSPACE to use the newly
created `benchmark_deps.bzl` function.
Having the copts set on a per-target level can lead to ODR violations
in some cases. Avoid this by ensuring the regex engine is picked
through compiler intrinsics in the header directly.
* Add myself to CONTRIBUTORS under the corp CLA for Stripe, Inc.
* Add support for building with Bazel.
Limitations compared to existing CMake rules:
* Defaults to using C++11 `<regex>`, with an override via Bazel flag
`--define` of `google_benchmark.have_regex`. The TravisCI config sets
the regex implementation to `posix` because it uses ancient compilers.
* Debug vs Opt mode can't be set per test. TravisCI runs all the tests
in debug mode to satisfy `diagnostics_test`, which depends on `CHECK`
being live.
* Set Bazel workspace name so other repos can refer to it by stable name.
This is recommended by the Bazel style guide to avoid each dependent
workspace defining its own name for the dependency.
