* clang-tidy fixes
* Workaround for PYPY WIN exitcode None
* Revert "Temporarily pull in snapshot of PR #4246"
This reverts commit 23ac16e859150f27fda25ca865cabcb4444e0770.
* Another workaround for PYPY WIN exitcode None
* Clean up how the tests are run "run in process" Part 1: uniformity
* 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).

* bugfix: contains now throws an exception if the key is not hashable
* Fix tests and improve robustness
* Remove todo
* Workaround PyPy corner case
* PyPy xfail
* Fix typo
* fix xfail
* Make clang-tidy happy
* Remove redundant exc checking
* 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.

* Add comment pointing to PR, for easy reference.
* Add debug fprintf to test_interpreter.cpp
* Update `sys.path` from `PYTHONPATH` in Python >= 3.11 branch of `initialize_interpreter()`
* Use `config.isolated = 0; config.use_environment = 1;`
As suggsted by @vstinner here: https://github.com/pybind/pybind11/pull/4119#issuecomment-1219442853

* Fix clang-tidy error.
* Use `_putenv_s()` under Windows.
* Fix clang-tidy error: argument name ... in comment does not match parameter name
* Remove slash from PYTHONPATH addition, to work around Windows slash-vs-backslash issue.
* Use `py::str(...)` instead of `.attr("__str__")` as suggested by @skylion007

* Remove all `:BOOL` as suggested by @henryiii
* For PyPy only, re-enable old behavior (likely to mask bugs), to avoid segfault with unknown root cause.
Change prompted by https://github.com/pybind/pybind11/issues/4075

* Add test_pypy_oserror_normalization
* Disable new `PYPY_VERSION` `#if`, to verify that the new test actually fails.
* Restore PYPY_VERSION workaround and update comment to reflect what was learned.
* [ci skip] Fix trivial oversight in comment.
* Disable implicit conversion from `0` to `pybind11::handle`.
* Reverse or-ed condition in an attempt to resolve GCC 8.3.0 errors (i386/debian:buster).
* Trying the simpler `std::is_same<T, PyObject *>`
* Add implicit_conversion_from_pytorch_THPObjectPtr_to_handle test.
* Accommodate types with implicit conversions to `PyObject *`, other than `handle` & `handle` subclasses, or integral types.
* 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`.

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.
* Fixed PyPy build
* Moved normalization to error_already_set ctor
* Fix merge bugs
* Fix more merge errors
* Improve formatting
* Improve error message in rare case
* Revert back if statements
* Fix clang-tidy
* Try removing mutable

* See if we still need debug
* Remove unnecessary mutable
* Report "FATAL failure building pybind11::error_already_set error_string" and terminate process.
* Try specifying noexcept again
* Try explicit ctor
* default ctor is noexcept too
* 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.

* 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.

* 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.
* Add test case for failing to create weakref
* Add Debug asserts for pybind11 fail
* Make error handling more pythonic
* Does this fix PyPy?
* Adapt test to PyPy differences
* Simplify test to remove redundancy

* Expand string_view support to str, bytes, memoryview
1. Allows constructing a str or bytes implicitly from a string_view;
this is essentially a small shortcut allowing a caller to write
`py::bytes{sv}` rather than `py::bytes{sv.data(), sv.size()}`.
2. Allows implicit conversion *to* string_view from py::bytes -- this
saves a fair bit more as currently there is no simple way to get such
a view of the bytes without copying it (or resorting to Python API
calls).
(This is not done for `str` because when the str contains unicode we
have to allocate to a temporary and so there might not be some string
data we can properly view without owning.)
3. Allows `memoryview::from_memory` to accept a string_view. As with
the other from_memory calls, it's entirely your responsibility to
keep it alive.
This also required moving the string_view availability detection into
detail/common.h because this PR needs it in pytypes.h, which is higher
up the include chain than cast.h where it was being detected currently.
* Move string_view include to pytypes.h
* CI-testing a fix for the "ambiguous conversion" issue.

* Fix py::kw_only when used before the first arg of a method
The implicit space for the `self` argument isn't added until we hit the
first argument, but this wasn't being done for kw_only or pos_only, and
so a kw_only before the first argument would break.
This fixes it by properly checking whether we need to add the self arg.
(The pos_only issue here was extremely mild -- you didn't get the `/` in
the docstring, but AFAICT it has no other effect since there are no
meaningful arguments before it anyway).
* Style changes
- rename check_have_self_arg -> append_self_arg_if_needed
- move the argument name inline comments before the args instead of
after

* override: Fix wrong caching of the overrides
There was a problem when the python type, which was stored in override
cache for C++ functions, was destroyed and the record wasn't removed from the
override cache. Therefor, dangling pointer was stored there. Then when the
memory was reused and new type was allocated at the given address and the
method with the same name (as previously stored in the cache) was actually
overridden in python, it would wrongly find it in the override cache for C++
functions and therefor override from python wouldn't be called.
The fix is to erase the type from the override cache when the type is destroyed.
* test: Pass by const ref instead of by value (clang-tidy)
* test: Rename classes and move to different files
Rename the classes and files so they're no too generic. Also, better place to
test the stuff is in test_virtual_functions.cpp/.py as we're basically testing
the virtual functions/trampolines.
* Add TODO for erasure code

On Unix, setuptools prepends $CFLAGS and $CPPFLAGS to the compiler flags
(they always come before extra_compile_args and anything else; see
distutils.sysconfig.customize_compiler). In practice, the environment
variables are useful e.g. to quickly generate a debug build (e.g. by
setting CFLAGS=-g), but Pybind11Extension currently unconditionally
overwrites this with -g0.
Instead, check the environment variables and only insert -g0 if not
overridden by them.
* fix: add missing std::forward calls
Two of the four cpp_function overloads are missing std::forward calls, which seems like a simple oversight.

* Simply has_kw_only_args handling
This simplifies tracking the number of kw-only args by instead tracking
the number of positional arguments (which is really what we care about
everywhere this is used).
* Allow keyword-only arguments to follow py::args
This removes the constraint that py::args has to be last (or
second-last, with py::kwargs) and instead makes py::args imply
py::kw_only for any remaining arguments, allowing you to bind a function
that works the same way as a Python function such as:
def f(a, *args, b):
return a * b + sum(args)
f(10, 1, 2, 3, b=20) # == 206
With this change, you can bind such a function using:
m.def("f", [](int a, py::args args, int b) { /* ... */ },
"a"_a, "b"_a);
Or, to be more explicit about the keyword-only arguments:
m.def("g", [](int a, py::args args, int b) { /* ... */ },
"a"_a, py::kw_only{}, "b"_a);
(The only difference between the two is that the latter will fail at
binding time if the `kw_only{}` doesn't match the `py::args` position).
This doesn't affect backwards compatibility at all because, currently,
you can't have a py::args anywhere except the end/2nd-last.

* fix: the types for return_value_policy_override in optional_caster
`return_value_policy_override` was not being applied correctly in
`optional_caster` in two ways:
- The `is_lvalue_reference` condition referenced `T`, which was the
`optional<T>` type parameter from the class, when it should have used `T_`,
which was the parameter to the `cast` function. `T_` can potentially be a
reference type, but `T` will never be.
- The type parameter passed to `return_value_policy_override` should be
`T::value_type`, not `T`. This matches the way that the other STL container
type casters work.
The result of these issues was that a method/property definition which used a
`reference` or `reference_internal` return value policy would create a Python
value that's bound by reference to a temporary C++ object, resulting in
undefined behavior. For reasons that I was not able to figure out fully, it
seems like this causes problems when using old versions of `boost::optional`,
but not with recent versions of `boost::optional` or the `libstdc++`
implementation of `std::optional`. The issue (that the override to
`return_value_policy::move` is never being applied) is present for all
implementations, it just seems like that somehow doesn't result in problems for
the some implementation of `optional`. This change includes a regression type
with a custom optional-like type which was able to reproduce the issue.
Part of the issue with using the wrong types may have stemmed from the type
variables `T` and `T_` having very similar names. This also changes the type
variables in `optional_caster` to use slightly more descriptive names, which
also more closely follow the naming convention used by the other STL casters.
