Use `PyCapsule_Destructor` (part of the stable Python ABI) instead of spelling out the C `typedef`.
The deprecation message is misleading. Replace with a message pointing to another existing ctor.
Background: According to @wjakob the original motivation for deprecating the ctor (in PR #752) was to hide Python C API details, but PR #902 brought those back with a new ctor, it cannot be avoided. Having a `PyCapsule_Destructor` or a `void (*destructor)(void *)` are two separate and valid use cases.
* Reproducer for issue encountered in smart_holder update.
* clang-tidy compatibility (untested).
* Add `enable_if_t` to workaround.
* Bug fix: Move `PYBIND11_USING_WORKAROUND_FOR_CUDA_11_4_THROUGH_8` determination to detail/common.h
So that it actually is defined in pybind11.h
* Try using the workaround (which is nicer than the original code) universally.
* Reduce reproducer for CUDA 11.7 issue encountered in smart_holder update.
This commit tested in isolation on top of current master + first version of reproducer (62311eb431).
Succeeds with Debian Clang 14.0.6 C++17 (and probably all other compilers).
Fails for CUDA 11.7:

```
* fix: PyCapsule_GetDestructor is allowed to return a nullptr destructor
Previously, this code would error out if the destructor happened to be
a nullptr. This is incorrect. nullptrs are allowed for capsule
destructors.
"It is legal for a capsule to have a NULL destructor. This makes a
NULL return code somewhat ambiguous; use PyCapsule_IsValid() or
PyErr_Occurred() to disambiguate."
See:
https://docs.python.org/3/c-api/capsule.html#c.PyCapsule_GetDestructor
I noticed this while working on a type caster related to #3858 DLPack
happens to allow the destructor not to be defined on a capsule, and I
encountered such a case. See:
e2bdd3bee8/include/dlpack/dlpack.h (L219)
* Add test for the fix.
* Update tests/test_pytypes.cpp
I tried this locally and it works!
I never knew that there are cases where `reinterpret_cast` does not work but `static_cast` does. Let's see if all compilers are happy with this.

* Fix copy-paste mishap (picked wrong name).
* Revamp SFINAE construct to actually fix the pytorch issue (already validated against pytorch proper).
The first version of the reduced pytorch code was critically missing the move ctor. The first version of the accompanying test was meaningless.
Note: It turns out the `!std::is_arithmetic<T>` condition is not needed: `int` is not in general implicitly convertible to `PyObject *`, only the literal `0` is.
* Use `NOLINT(performance-noexcept-move-constructor)` for reduced code from the wild (rather than changing the code).
* Use any_of, all_of, negation. It turns out to clang-format nicer.
* Clean up comments for changed code.
* Reduce pytorch situation further, add test for operator ... const.
* Use `none_of` as suggested by @skylion007
* Add `pure_compile_tests_for_handle_from_PyObject_pointers()`
* Fix inconsequential oversight (retested).
* Factor our `is_pyobj_ptr_or_nullptr_t` to make the SFINAE conditions more readable.
* Remove stray line (oversight).
* Make the `pure_compile_tests_for_handle_from_PyObject_pointers()` "rhs-const-complete", too.
* Remove the temporary PYBIND11_UNDO_PR4008 `#ifdef`.
Very minor refactoring to ease development and debugging.
Having to declare a local `std::string` has bugged me many times. Nice to get this little nuisance out of the way.

When converting an array to an Eigen matrix, ignore the strides if any
dimension size is 0. If the array is empty, the strides aren't relevant,
and especially numpy ≥ 1.23 explicitly sets the strides to 0 in this
case. (See numpy commit dd5ab7b11520.)
Update tests to verify that this works, and continues to work.
* emplace field descriptors
* reserve sufficient capacity
* remove std::move
* properly iterate through dict
* make handle casting more explicit
* Revert to old dict api
* error_already_set::what() is now constructed lazily
Prior to this commit throwing error_already_set was expensive due to the
eager construction of the error string (which required traversing the
Python stack). See #1853 for more context and an alternative take on the
issue.
Note that error_already_set no longer inherits from std::runtime_error
because the latter has no default constructor.
* Do not attempt to normalize if no exception occurred
This is not supported on PyPy-2.7 5.8.0.
* Extract exception name via tp_name
This is faster than dynamically looking up __name__ via GetAttrString.
Note though that the runtime of the code throwing an error_already_set
will be dominated by stack unwinding so the improvement will not be
noticeable.
Before:
396 ns ± 0.913 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
After:
277 ns ± 0.549 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
Benchmark:
const std::string foo() {
PyErr_SetString(PyExc_KeyError, "");
const std::string &s = py::detail::error_string();
PyErr_Clear();
return s;
}
PYBIND11_MODULE(foo, m) {
m.def("foo", &::foo);
}
* Reverted error_already_set to subclass std::runtime_error
* Revert "Extract exception name via tp_name"
The implementation of __name__ is slightly more complex than that.
It handles the module name prefix, and heap-allocated types. We could
port it to pybind11 later on but for now it seems like an overkill.
This reverts commit f1435c7e6b.
* Cosmit following @YannickJadoul's comments
Note that detail::error_string() no longer calls PyException_SetTraceback
as it is unncessary for pretty-printing the exception.
* Fixed PyPy build
* Moved normalization to error_already_set ctor
* Fix merge bugs
* Fix more merge errors

* Apply reviewer suggestions, simplify code, and make helper method private
* Remove unnecessary include
* Clang-Tidy fix
* detail::obj_class_name(), fprintf with [STDERR], [STDOUT] tags, polish comments
* consistently check m_lazy_what.empty() also in production builds
* Make a comment slightly less ambiguous.
* Bug fix: Remove `what();` from `restore()`.
It sure would need to be guarded by `if (m_type)`, otherwise `what()` fails and masks that no error was set (see update unit test). But since `error_already_set` is copyable, there is no point in releasing m_type, m_value, m_trace, therefore we can just as well avoid the runtime overhead of force-building `m_lazy_what`, it may never be used.
* Replace extremely opaque (unhelpful) error message with a truthful reflection of what we know.
* Fix clang-tidy error [performance-move-constructor-init].
* Make expected error message less specific.
* Various changes.
* bug fix: error_string(PyObject **, ...)
* Putting back the two eager PyErr_NormalizeException() calls.
* Change error_already_set() to call pybind11_fail() if the Python error indicator not set. The net result is that a std::runtime_error is thrown instead of error_already_set, but all tests pass as is.
* Remove mutable (fixes oversight in the previous commit).
* Normalize the exception only locally in error_string(). Python 3.6 & 3.7 test failures expected. This is meant for benchmarking, to determine if it is worth the trouble looking into the failures.
* clang-tidy: use auto
* Use `gil_scoped_acquire_local` in `error_already_set` destructor. See long comment.
* For Python < 3.8: `PyErr_NormalizeException` before `PyErr_WriteUnraisable`
* Go back to replacing the held Python exception with then normalized exception, if & when needed. Consistently document the side-effect.
* Slightly rewording comment. (There were also other failures.)
* Add 1-line comment for obj_class_name()
* Benchmark code, with results in this commit message.

* Removing test_perf_error_already_set (copies are under 7765113fbb).
* Avoid gil and scope overhead if there is nothing to release.
* Restore default move ctor. "member function" instead of "function" (note that "method" is Python terminology).
* Delete error_already_set copy ctor.
* Make restore() non-const again to resolve clang-tidy failure (still experimenting).
* Bring back error_already_set copy ctor, to see if that resolves the 4 MSVC test failures.
* Add noexcept to error_already_set copy & move ctors (as suggested by @skylion007 IIUC).
* Trying one-by-one noexcept copy ctor for old compilers.
* Add back test covering copy ctor. Add another simple test that exercises the copy ctor.
* Exclude more older compilers from using the noexcept = default ctors. (The tests in the previous commit exposed that those are broken.)
* Factor out & reuse gil_scoped_acquire_local as gil_scoped_acquire_simple
* Guard gil_scoped_acquire_simple by _Py_IsFinalizing() check.
* what() GIL safety
* clang-tidy & Python 3.6 fixes
* Use `gil_scoped_acquire` in dtor, copy ctor, `what()`. Remove `_Py_IsFinalizing()` checks (they are racy: https://github.com/python/cpython/pull/28525).
* Remove error_scope from copy ctor.
* Add `error_scope` to `get_internals()`, to cover the situation that `get_internals()` is called from the `error_already_set` dtor while a new Python error is in flight already. Also backing out `gil_scoped_acquire_simple` change.
* Add `FlakyException` tests with failure triggers in `__init__` and `__str__`
THIS IS STILL A WORK IN PROGRESS. This commit is only an important resting point.
This commit is a first attempt at addressing the observation that `PyErr_NormalizeException()` completely replaces the original exception if `__init__` fails. This can be very confusing even in small applications, and extremely confusing in large ones.
* Tweaks to resolve Py 3.6 and PyPy CI failures.
* Normalize Python exception immediately in error_already_set ctor.
For background see: https://github.com/pybind/pybind11/pull/1895#issuecomment-1135304081
* Fix oversights based on CI failures (copy & move ctor initialization).
* Move @pytest.mark.xfail("env.PYPY") after @pytest.mark.parametrize(...)
* Use @pytest.mark.skipif (xfail does not work for segfaults, of course).
* Remove unused obj_class_name_or() function (it was added only under this PR).
* Remove already obsolete C++ comments and code that were added only under this PR.
* Slightly better (newly added) comments.
* Factor out detail::error_fetch_and_normalize. Preparation for producing identical results from error_already_set::what() and detail::error_string(). Note that this is a very conservative refactoring. It would be much better to first move detail::error_string into detail/error_string.h
* Copy most of error_string() code to new error_fetch_and_normalize::complete_lazy_error_string()
* Remove all error_string() code from detail/type_caster_base.h. Note that this commit includes a subtle bug fix: previously error_string() restored the Python error, which will upset pybind11_fail(). This never was a problem in practice because the two PyType_Ready() calls in detail/class.h do not usually fail.
* Return const std::string& instead of const char * and move error_string() to pytypes.h
* Remove gil_scope_acquire from error_fetch_and_normalize, add back to error_already_set
* Better handling of FlakyException __str__ failure.
* Move error_fetch_and_normalize::complete_lazy_error_string() implementation from pybind11.h to pytypes.h
* Add error_fetch_and_normalize::release_py_object_references() and use from error_already_set dtor.
* Use shared_ptr for m_fetched_error => 1. non-racy, copy ctor that does not need the GIL; 2. enables guard against duplicate restore() calls.
* Add comments.
* Trivial renaming of a newly introduced member function.
* Workaround for PyPy
* Bug fix (oversight). Only valgrind got this one.
* Use shared_ptr custom deleter for m_fetched_error in error_already_set. This enables removing the dtor, copy ctor, move ctor completely.
* Further small simplification. With the GIL held, simply deleting the raw_ptr takes care of everything.
* IWYU cleanup
```
iwyu version: include-what-you-use 0.17 based on Debian clang version 13.0.1-3+build2
```
Command used:
```
iwyu -c -std=c++17 -DPYBIND11_TEST_BOOST -Iinclude/pybind11 -I/usr/include/python3.9 -I/usr/include/eigen3 include/pybind11/pytypes.cpp
```
pytypes.cpp is a temporary file: `#include "pytypes.h"`
The raw output is very long and noisy.
I decided to use `#include <cstddef>` instead of `#include <cstdio>` for `std::size_t` (iwyu sticks to the manual choice).
I ignored all iwyu suggestions that are indirectly covered by `#include <Python.h>`.
I manually verified that all added includes are actually needed.

* Add frozenset, and allow it cast to std::set
For the reverse direction, std::set still casts to set. This is in concordance with the behavior for sequence containers, where e.g. tuple casts to std::vector but std::vector casts to list.
Extracted from #3886.
* Rename set_base to any_set to match Python C API
since this will be part of pybind11 public API
* PR: static_cast, anyset
* Add tests for frozenset
and rename anyset methods
* Remove frozenset default ctor, add tests
Making frozenset non-default constructible means that we need to adjust pyobject_caster to not require that its value is default constructible, by initializing value to a nil handle. This also allows writing C++ functions taking anyset, and is arguably a performance improvement, since there is no need to allocate an object that will just be replaced by load.
Add some more tests, including anyset::empty, anyset::size, set::add and set::clear.

* Clear Python error state if pybind11::weakref() fails.
The weakref() constructor calls pybind11_fail() without clearing any
Python interpreter error state. If a client catches the C++ exception
thrown by pybind11_fail(), the Python interpreter will be left in an
error state.
