* Copy clang 17 compatibility fixes from PR #4762 to a separate PR. * static py::exception<> -> static py::handle * Add `py::set_error()` but also try the suggestion of @malfet (https://github.com/pytorch/pytorch/pull/106401#pullrequestreview-1559961407). * clang 17 compatibility fixes (#4767) * Copy clang 17 compatibility fixes from PR #4762 to a separate PR. * Add gcc:13 C++20 * Add silkeh/clang:16-bullseye C++20 * chore(deps): update pre-commit hooks (#4770) updates: - [github.com/psf/black: 23.3.0 → 23.7.0](https://github.com/psf/black/compare/23.3.0...23.7.0) - [github.com/astral-sh/ruff-pre-commit: v0.0.276 → v0.0.281](https://github.com/astral-sh/ruff-pre-commit/compare/v0.0.276...v0.0.281) - [github.com/asottile/blacken-docs: 1.14.0 → 1.15.0](https://github.com/asottile/blacken-docs/compare/1.14.0...1.15.0) Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> * docs: Remove upper bound on pybind11 in example pyproject.toml for setuptools (#4774) * docs: Remove upper bound on pybind11 in example pyproject.toml for setuptools * Update docs/compiling.rst --------- Co-authored-by: Henry Schreiner <HenrySchreinerIII@gmail.com> * Provide better type hints for a variety of generic types (#4259) * Provide better type hints for a variety of generic types * Makes better documentation * tuple, dict, list, set, function * Move to py::typing * style: pre-commit fixes * Update copyright line with correct year and actual author.

Grosse-Kunstleve <rwgk@google.com> Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> * Use `py::set_error()` everywhere possible (only one special case, in common.h). Overload `py::set_error(py::handle, py::handle)`. Change back to `static py::handle exc = ... .release();` Deprecate `py::exception<>::operator()` * Add `PYBIND11_WARNING_DISABLE` for INTEL and MSVC (and sort alphabetically). * `PYBIND11_WARNING_DISABLE_INTEL(10441)` does not work. For ICC only, falling back to the recommended `py::set_error()` to keep the testing simple. It is troublesome to add `--diag-disable=10441` specifically for test_exceptions.cpp, even that is non-ideal because it covers the entire file, not just the one line we need it for, and the value of exercising the trivial deprecated `operator()` on this one extra platform is practically zero. * Fix silly oversight. * NVHPC 23.5.0 generates deprecation warnings. They are currently not treated as errors, but falling back to using `py::set_error()` to not have to deal with that distraction. --------- Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Keto D.
