The Windows toolchain detection fix made it into Bazel 6.3.0, so the CI
should work again with the re-enabled `windows-latest` marker.
Require Bazel 6.3.0 in the Linux container setup in `cibuildwheel`.
The dependencies are contained in the `pyproject.toml` since it was added.
Switches to header and source file globbing instead of manually listing
the files. The selects for different platforms are removed, as a tradeoff,
we take a single- to low double-digit hit in wheel sizes (between 5 percent
zipped and 12% installed on MacOS 13.4).
The newly created `pyproject.toml` contains all static metadata as well
as the readme and version as dynamic arguments, to be read by setuptools
during the build.
What is left in the `setup.py` for now is the custom Bazel extension
class, since that is not properly supported yet.
* Add pfm CI actions for bazel
* Fix problems in unit test.
* Undo enabling the CI tests for pfm - github CI machines seemingly do not support performance counters.
* Remove commented code - can be revisited in github history when needed, and there's a comment explaining the rationale behind the new test code.

* 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

BENCHMARK_HAVE_STD_REGEX is not used but HAVE_STD_REGEX like the other two choices, i.e. HAVE_GNU_POSIX_REGEX and HAVE_POSIX_REGEX.

* Address warnings on NVIDIA nvc++
Types of warnings were being generated:
1. Deprecated warnings - solved by defining the relevant BENCHMARK_*
macros for nvc++ and adding pragma suppress on a couple of .cc files
2. Setup/TearDown const vs non-const partial override - solved by
adding non-const version
3. Static but not referenced - added diagnostic suppress for that file
* Modified manually to comply with CD/CI
* Revert partial override
* Suppress warnings from tests if compiler is NVHPC

* [FR] Provide public accessors to benchmark name and arguments #1551
* Update AUTHORS and CONTRIBUTORS
* Update benchmark_register.cc
* Fix lint formatting
Build breaks when -Werror is turned on because of unhandled cases of
inocuous/pedantic warnings. Adopted the same solution as for Intel PGI
compiler - just disable -Werror manually, unless BENCHMARK_FORCE_WERROR
is enabled. Fixes#1556.
* Update AUTHORS/CONTRIBUTORS
* Fix examples with deprecated DoNotOptimize API
The const-reference API to DoNotOptimize was deprecated with #1493. Some
examples in the user guide are using exactly that deprecated interface.
This fixes that by passing non-const lvalues instead. Fixes#1566
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.
* Refactoring of PerfCounters infrastructure
The main feature in this pull request is the removal of the static
sharing of PerfCounters and instead creating them at the top
`RunBenchmarks()` function where all benchmark runners are created. A
single PerfCountersMeasurement object is created and then shared with
all the new BenchmarkRunners objects, one per existing benchmark.
Other features conflated here in this PR are:
- Added BENCHMARK_DONT_OPTIMIZE macro in global scope
- Removal of the `IsValid()` query, being replaced by checking the
number of remaining counters after validity tests
- Refactoring of all GTests to reflect the changes and new semantics
- extra comments throughout the new code to clarify intent
It was extremely hard to separate all those features in different PRs
as requested since they are so interdependent on each other so I'm just
pushing them altogether and asking for forgiveness.
This PR comes replacing PRs 1555 and 1558 which have been closed.
* Fixed whitespace issue with clang-format
My clang-format insists in deleting this single white space on line 601
while Github's clang format breaks when it is added. I had to disable
format-on-save to check-in this revert change.
I'm using clang 14.0.6.
* Filter performance counter names, not invalidate all
Currently, the performance counters are validated while they
are being created and one failure returns NoCounters(), ie it
effecitvely invalidates all the counters.
I would like to propose a new behavior: filter instead. If an
invalid name is added to the counter list, or if that particular
counter is not supported on this platform, that counter is dropped
from the list and an error messages is created, while all the
other counters remain active.
This will give testers a peace of mind that if one mistake is made
or if something is changed or removed from libpfm, their entire
test will not be invalidated. This feature gives more tolerance
with respect to versioning.
Another positive is that testers can now input a superset of all
desired counters for all platforms they support and just let
Benchmark drop all those that are not supported, although it will
create quite a lot of noise down the line, in which case perhaps
we should drop silently or make a consolidated, single error line
but this was not implemented in this change set.
* Removed unused helper type.
