* stl.h: Use C++11 range-loops with const reference
This saves copy-ctor and dtor for non-trivial types by value
Found by clazy (range-loop-reference)
* test_smart_ptr.cpp cleanup
Introduce `pointer_set<T>`

* Equivalent of 5718e4d080

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:

* 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

* Update skipif for Python 3.12a7 (the WIP needs to be handled in a separate PR).
* 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 PyConfig_InitPythonConfig instead of PyConfig_InitIsolatedConfig
* add unit test for default python configuration

* Resolve flake8 error by replacing `pytest.raises(Exception)` with `SystemError`
* Also remove the obsolete comment.
* Tweak comment instead of removing it.
* 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.

* Clean up how the tests are run "run in process" Part 2: use `@pytest.mark.parametrize` and clean up the naming.
* Skip some tests `#if defined(THREAD_SANITIZER)` (tested with TSAN using the Google-internal toolchain).
* Run all tests again but ignore ThreadSanitizer exitcode 66 (this is less likely to mask unrelated ThreadSanitizer issues in the future).
* bug fix: missing common.h include before using `PYBIND11_SIMPLE_GIL_MANAGEMENT`
For the tests in the github CI this does not matter, because
`PYBIND11_SIMPLE_GIL_MANAGEMENT` is always defined from the command line,
but when monkey-patching common.h locally, it matters.
* if process.exitcode is None: assert t_delta > 9.9
* More sophisiticated `_run_in_process()` implementation, clearly reporting `DEADLOCK`, additionally exercised via added `intentional_deadlock()`
* Wrap m.intentional_deadlock in a Python function, for `ForkingPickler` compatibility.
```
> ForkingPickler(file, protocol).dump(obj)
E TypeError: cannot pickle 'PyCapsule' object
```
Observed with all Windows builds including mingw but not PyPy, and macos-latest with Python 3.9, 3.10, 3.11 but not 3.6.
* Add link to potential solution for WOULD-BE-NICE-TO-HAVE feature.
* Add `SKIP_IF_DEADLOCK = True` option, to not pollute the CI results with expected `DEADLOCK` failures while we figure out what to do about them.
* Add COPY-PASTE-THIS: gdb ... command (to be used for debugging the detected deadlock)
* style: pre-commit fixes
* Do better than automatic pre-commit fixes.
* Add `PYBIND11_SIMPLE_GIL_MANAGEMENT` to `pytest_report_header()` (so that we can easily know when harvesting deadlock information from the CI logs).

* 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).

* 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.

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.
* 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.

* 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.

Thread model: posix
* Changing call_repetitions_target_elapsed_secs to 0.1 for regular unit testing.
* Adding in `recursion_depth`
* Optimized ctor
* Fix silly bug in recurse_first_then_call()
* Add tests that have equivalent PyErr_Fetch(), PyErr_Restore() but no try-catch.
* Add call_error_string to tests. Sample only recursion_depth 0, 100.
* Show lazy-what speed-up in percent.
* Include real_work in benchmarks.
* Replace all PyErr_SetString() with generate_python_exception_with_traceback()
* Better organization of test loops.
* Add test_error_already_set_copy_move
* Fix bug in newly added test (discovered by clang-tidy): actually use move ctor
* MSVC detects the unreachable return
* change test_perf_error_already_set.py back to quick mode
* Inherit from std::exception (instead of std::runtime_error, which does not make sense anymore with the lazy what)
* Special handling under Windows.
* print with leading newline
* 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.
