* Equivalent of 5718e4d080
* Resolve clang-tidy errors.
* Moving test_PPCCInit() first changes the behavior!
* Resolve new Clang dev C++11 errors:
```

This reverts commit d37b5409d4.
* One way to deal with the order dependency issue. This is not the best way, more like a proof of concept.
* Move test_PC() first again.
* Add `all_type_info_add_base_most_derived_first()`, use in `all_type_info_populate()`
* Revert "One way to deal with the order dependency issue. This is not the best way, more like a proof of concept."
This reverts commit eb09c6c1b9.
* clang-tidy fixes (automatic)
* Add `is_redundant_value_and_holder()` and use to avoid forcing `__init__` overrides when they are not needed.
* Streamline implementation and avoid unsafe `reinterpret_cast<instance *>()` introduced with PR #2152
The `reinterpret_cast<instance *>(self)` is unsafe if `__new__` is mocked,
which was actually found in the wild: the mock returned `None` for `self`.
This was inconsequential because `inst` is currently cast straight back to
`PyObject *` to compute `all_type_info()`, which is empty if `self` is not
a pybind11 `instance`, and then `inst` is never dereferenced. However, the
unsafe detour through `instance *` is easily avoided and the updated
implementation is less prone to accidents while debugging or refactoring.
* Fix actual undefined behavior exposed by previous changes.
It turns out the previous commit message is incorrect, the `inst` pointer is actually dereferenced, in the `value_and_holder` ctor here:
f3e0602802/include/pybind11/detail/type_caster_base.h (L262-L263)
```
259 // Main constructor for a found value/holder:

* Roundtrip through unique pointer with custom deleter.
Currently failing.
* Ensure the custom deleter is copied back to the unique pointer.
Feels like there's still a gap around the raw pointer flavour, but this at least
makes the unit test of the previous commit succeed.
* Add deleter roundtrip for const atyp.
Currently failing, custom deleter is lost.
* Fix storing deleter for const unique ptr.
Unit test from the previous commit passes.
* Remove SFINEA deleter assignment.
At the construction of the smart holder, it is either a del_fun, or a default constructed deleter, so this complexity is unnecessary.
* Clang format.
* Fixes for ci.
Clang 3.6 requires the extra constructors in the custom_deleter.
* fix(smart_holder): Loosen requirement on deleter to be default constructible.
And some other PR feedback.
* fix(smart_holder): Custom deleter in unit tests traces constructions.
* fix(smart_holder): Use pybind11_fail instead of assert.
* fix(smart_holder): Add unit tests for the default constructible deleter.
* fix(smart_holder): Use regex matching for deleter constructors in unit tests.
* Store `std::function<void (void *)>` del_fun; in `guarded_delete`
* Specialize the simple common case.
Using a `union` is complicated: https://en.cppreference.com/w/cpp/language/union
> If members of a union are classes with user-defined constructors and destructors, to switch the active member, explicit destructor and placement new are generally needed:
Using `std::variant` increases compile-time overhead.
It is currently unclear how much these effects matter in practice: optimization left for later.
* Add one test case (more later).
* Add `const` to resolve clang-tidy error.

* Update pytest (which removes their dependency on py)
The py library through 1.11.0 for Python allows remote attackers to conduct a ReDoS (Regular expression Denial of Service) attack via a Subversion repository with crafted info data, because the InfoSvnCommand argument is mishandled.
The particular codepath in question is the regular expression at py._path.svnurl.InfoSvnCommand.lspattern and is only relevant when dealing with subversion (svn) projects. Notably the codepath is not used in the popular pytest project. The developers of the pytest package have released version 7.2.0 which removes their dependency on py. Users of pytest seeing alerts relating to this advisory may update to version 7.2.0 of pytest to resolve this issue. See https://github.com/pytest-dev/py/issues/287#issuecomment-1290407715 for additional context.

* 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.

* Add `npy_format_descriptor<PyObject *>` to enable `py::array_t<PyObject *>` to/from-python conversions.
* resolve clang-tidy warning
* Use existing constructor instead of adding a static method. Thanks @Skylion007 for pointing out.
* Add `format_descriptor<PyObject *>`
Trivial addition, but still in search for a meaningful test.
* Add test_format_descriptor_format
* Ensure the Eigen `type_caster`s do not segfault when loading arrays with dtype=object
* Use `static_assert()` `!std::is_pointer<>` to replace runtime guards.
* Add comments to explain how to check for ref-count bugs. (NO code changes.)
* Make the "Pointer types ... are not supported" message Eigen-specific, as suggested by @Lalaland. Move to new pybind11/eigen/common.h header.
* Change "format_descriptor_format" implementation as suggested by @Lalaland. Additional tests meant to ensure consistency between py::format_descriptor<>, np.array, np.format_parser turn out to be useful only to highlight long-standing inconsistencies.
* resolve clang-tidy warning
* Account for np.float128, np.complex256 not being available on Windows, in a future-proof way.
* Fully address i|q|l ambiguity (hopefully).
* Remove the new `np.format_parser()`-based test, it's much more distracting than useful.
* Use bi.itemsize to disambiguate "l" or "L"
* Use `py::detail::compare_buffer_info<T>::compare()` to validate the `format_descriptor<T>::format()` strings.
* Add `buffer_info::compare<T>` to make `detail::compare_buffer_info<T>::compare` more visible & accessible.
* silence clang-tidy warning
* pytest-compatible access to np.float128, np.complex256
* Revert "pytest-compatible access to np.float128, np.complex256"
This reverts commit e9a289c50f.
* Use `sizeof(long double) == sizeof(double)` instead of `std::is_same<>`
* Report skipped `long double` tests.
* Change the name of the new `buffer_info` member function to `item_type_is_equivalent_to`. Add comment defining "equivalent" by example.
* Change `item_type_is_equivalent_to<>()` from `static` function to member function, as suggested by @Lalaland
* First version adding `__notes__` to `error_already_set::what()` output.
* Fix trivial oversight (missing adjustment in existing test).
* Minor enhancements of new code.
* Re-enable `cmake --target cpptest -j 2`
* Revert "Re-enable `cmake --target cpptest -j 2`"
This reverts commit 60816285e9.
* Add general comment explaining why the `error_fetch_and_normalize` code is so unusual.
* Reproducer for property setter with return type that is not wrapped.
* Use `py::class_<OptionsBase>()` to work around the return value conversion issue.
* WIP drop_return_value
* Remove struct drop_return_value
* Introduce `return_value_policy::return_none` for use by setters.
* Add `is_setter` to attr.h and use from `.def_property()`
* Merge the new test into test_methods_and_attributes
* Remove return_none return_value_policy again.
* Fix oversight (NOLINTNEXTLINE placement).
* Simplification (for the better) found while searching for a way to resolve GCC build failures.

* Bug fix: obvious in hindsight. I thought the original version was incrementing the reference count for None, but no.
Discovered via many failing tests in the wild (10s of thousands).
It is very tricky to construct a meaningful unit test for this bug specifically. It's unlikely to come back, because 10s of thousands of tests will fail again.
* Add `type_caster<PyObject>` (tests are still incomplete).
* Fix oversight (`const PyObject *`).
* Ensure `type_caster<PyObject>` only works for `PyObject *`
* Move `is_same_ignoring_cvref` into `detail` namespace.
* Add test_cast_nullptr
* Change is_same_ignoring_cvref from variable template to using.
```

```
* Remove `return_value_policy::reference_internal` `keep_alive` feature (because of doubts about it actually being useful).
* Add missing test, fix bug (missing `throw error_already_set();`), various cosmetic changes.
* Move `type_caster<PyObject>` from test to new include (pybind11/type_caster_pyobject_ptr.h)
* Add new header file to CMakeLists.txt and tests/extra_python_package/test_files.py
* Backport changes from https://github.com/google/pywrapcc/pull/30021 to https://github.com/pybind/pybind11/pull/4601
* Fix oversight in test (to resolve a valgrind leak detection error) and add a related comment in cast.h.
No production code changes.
Make tests more sensitive by using `ValueHolder` instead of empty tuples and dicts.
Manual leak checks with `while True:` & top command repeated for all tests.
* Add tests for interop with stl.h `list_caster`
(No production code changes.)
* Bug fix in test. Minor comment enhancements.
* Change `type_caster<PyObject>::name` to `object`, as suggested by @Skylion007
* Expand comment for the new `T cast(const handle &handle)` [`T` = `PyObject *`]
* Add `T cast(object &&obj)` overload as suggested by @Skylion007
The original suggestion leads to `error: call to 'cast' is ambiguous` (full error message below), therefore SFINAE guarding is needed.

* Testing
* Similar fix for std::vector
* Fix infinite recursion check:
1) Apply to is_copy_assignable additionally
2) Check infinite recursion for map-like types
* style: pre-commit fixes
* Optional commit that demonstrates the limitations of this PR
* Fix positioning of container bindings
The bindings were previously in a block that was only activated if numpy
was available.
* Suggestions from code review: API side
* Suggestions from code review: Test side
* Suggestions from code review
1) Renaming: is_recursive_container and
MutuallyRecursiveContainerPair(MV|VM)
2) Avoid ambiguous specializations of is_recursive_container
* Some little fixes
* Reordering of structs
* Add recursive checks for is_move_constructible
* Static testing for pybind11 type traits
* More precise checking of recursive types
Instead of a trait `is_recursive_container`, use a trait
`recursive_container_traits` with dependent type
`recursive_container_traits::type_to_check_recursively`.
So, instead of just checking if a type is recursive and then trying to
somehow deal with it, recursively-defined traits such as
is_move_constructible can now directly ask this trait where the
recursion should proceed.
* Review suggestions
1. Use std::conditional
2. Fix typo
* Remove leftover include from test

* Try using `std::hash<std::type_index>`, `std::equal_to<std::type_index>` everywhere.
From PR #4316 we know that types in the unnamed namespace in different translation units do not compare equal, as desired.
But do types in named namespaces compare equal, as desired?
* Revert "Try using `std::hash<std::type_index>`, `std::equal_to<std::type_index>` everywhere."
This reverts commit a06949a926.
* Use "our own name-based hash and equality functions" for `std::type_index` only under macOS, based on results shown under https://github.com/pybind/pybind11/pull/4316#issuecomment-1305097879
* Patch in PR #4313: Minimal reproducer for clash when binding types defined in the unnamed namespace.
* test_unnamed_namespace_b xfail for clang
* `PYBIND11_INTERNALS_VERSION 5`
* Add a note to docs/classes.rst
* For compatibility with Google-internal testing, test_unnamed_namespace_a & test_unnamed_namespace_b need to work when imported in any order.
* Trying "__GLIBCXX__ or Windows", based on observations from Google-internal testing.
* Try _LIBCPP_VERSION
* Account for libc++ behavior in tests and documentation.
* Adjust expectations for Windows Clang (and make code less redundant).
* Add WindowsClang to ci.yml
Added block transferred from PR #4321
* Add clang-latest to name that appears in the GitHub Actions web view.
* Tweak the note in classes.rst again.
* Add `pip install --upgrade pip`, Show env, cosmetic changes
Already tested under PR #4321
* Add macos_brew_install_llvm to ci.yml
Added block transferred from PR #4324
* `test_cross_module_exception_translator` xfail 'Homebrew Clang'
* Revert back to base version of .github/workflows/ci.yml (the ci.yml changes were merged under #4323 and #4326)
* Fixes for ruff
* Make updated condition in internals.h dependent on ABI version.
* Remove PYBIND11_TEST_OVERRIDE when testing with PYBIND11_INTERNALS_VERSION=10000000
* Selectively exercise cmake `-DPYBIND11_TEST_OVERRIDE`: ubuntu, macos, windows
Extra work added to quick jobs, based on timings below, to not increase the GHA start-to-last-job-finished time.

* Special handling of pybind11 objects to side-step try_as_void_ptr_capsule_get_pointer __getattr__ issues.
* Inspect `internals.registered_types_py` in `type_is_pybind11_class_()`
* Remove debug code in tests subdir.
* Clean up the modified `try_as_void_ptr_capsule_get_pointer()` implementation and new helper functions.
* Introduce `get_python_state_dict()`
* Conditional version bump for Python 3.12+
* Shuffle subexpressions to make the condition easier to understand (no change to logic).
* Make pybind11 ABI version 5 the minimum for Python 3.12+ (as suggested by @Lalaland)
* Add back condition for PYPY_VERSION, but keep it open for future PyPy versions.
* Fall back to simple `|| defined(PYPY_VERSION)`. `PY_VERSION_HEX` does not appear to be meaningful with PyPy.
* use C++17 syntax to get rid of recursive template instantiations for concatenating type signatures (#4587)
* Apply descr.h `src_loc` change (smart_holder PR #4022) to code added with master PR #4587
* Add test_class_sh_property_non_owning to CMakeLists.txt (fixes oversight in PR #4586)

* Create templated abstract classes KeysView, ValuesView and ItemsView, and implement them on-the-fly when wrapping any specific map type
* We don't want to wrap different ValuesView objects for double values and const double, for example, as both wrappers will be named ValuesView[float]
* Fallback to C++ names if key or values types are not wrapped
* Added a test for .keys(), .values() and .items() returning the same types for similarly-typed maps
* Fixed wrong use of auto in a declarator list: the two descriptions might have different types
* Fixes for clang-tidy issues: explicit single-argument constructor, using the 'override' keyword when overriding functions
* Bugfix for old versions of clang++, which seem to have trouble with the struct being defined inside a module, which was also needlessly ugly anyway
* Bugfix for clang++, which doesn't have some of the names in runtime uness they are specified to be static
* A fix for clang-tidy performance-inefficient-string-concatenation issues - I personally think this looks uglier, but it's probably worth it for clang-tidy to be happy
* Possible fix for clang++ linking issues - make the descriptions static constexpr to make sure they are known before linking
* Correct names for previously-wrapped types as keys/values of maps
* Bugfix - typo in type info names which caused things to segfault
* Apply suggestions from code review

* Use detail::remove_cvref_t instead of doing remove_cv and remove_reference separately
* Avoid names with double underscore, as they are reserved
* Improved testing for KeysView, ValuesView and ItemsView: check type names + stricter asserts
* Moved description logic to helper function in type_caster_base.h
* style: pre-commit fixes
* Fix a clang-tidy issue: do not use 'else' after 'return'
* Apply suggestion by @Skylion007, with additional trivial simplification.
