* 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.

* 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).

* Make clang-tidy happy

* 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.

* Mark tu_local_no_data_always_false operator bool as explicit (clang-tidy). See also: https://stackoverflow.com/questions/39995573/when-can-i-use-explicit-operator-bool-without-a-cast
* New PYBIND11_TYPE_CASTER_ODR_GUARD_STRICT option (current on by default).
* Add test_type_caster_odr_registry_values(), test_type_caster_odr_violation_detected_counter()
* Report UNEXPECTED: test_type_caster_odr_guard_2.cpp prevailed (but do not fail).
* Apply clang-tidy suggestion.
* Attempt to handle valgrind behavior.
* Another attempt to handle valgrind behavior.
* Yet another attempt to handle valgrind behavior.
* Trying a new direction: show compiler info & std for UNEXPECTED: type_caster_odr_violation_detected_count() == 0
* compiler_info MSVC fix. num_violations == 0 condition.
* assert pybind11_tests.compiler_info is not None
* Introduce `make_caster_intrinsic<T>`, to be able to undo the 2 changes from `load_type` to `load_type<T>`. This is to avoid breaking 2 `pybind11::detail::load_type()` calls found in the wild (Google global testing).
One of the breakages in the wild was: 0f0f600767/python/tensorstore/subscript_method.h (L61)
* Add test for stl.h / stl_bind.h mix.
Manually verified that the ODR guard detects the ODR violation:

* Remove PYBIND11_DETAIL_TYPE_CASTER_ACCESS_TRANSLATION_UNIT_LOCAL macro completely.
* Remove PYBIND11_TYPE_CASTER_SOURCE_FILE_LINE macro completely. Some small extra cleanup.
* Minor tweaks looking at the PR with a fresh eye.

* Fully document the ODR violations in the ODR guard itself and introduce `PYBIND11_TYPE_CASTER_ODR_GUARD_ON_IF_AVAILABLE`
* Update comment (incl. mention of deadsnakes known to not work as intended).
* Use no-destructor idiom for type_caster_odr_guard_registry, as suggested by @laramiel
* Fix clang-tidy error: 'auto reg' can be declared as 'auto *reg' [readability-qualified-auto,-warnings-as-errors]
* WIP
* Revert "WIP" (tu_local_no_data_always_false_base experiment).
This reverts commit 31e8ac562f.
* Change `PYBIND11_TYPE_CASTER_ODR_GUARD_ON` to `PYBIND11_ENABLE_TYPE_CASTER_ODR_GUARD`, based on a suggestion by @rainwoodman
* Improved `#if` determining `PYBIND11_ENABLE_TYPE_CASTER_ODR_GUARD`, based on suggestion by @laramiel

* Rename macro to `PYBIND11_DETAIL_TYPE_CASTER_ODR_GUARD_IMPL_DEBUG`, as suggested by @laramiel
* Tweak comments some more (add "white hat hacker" analogy).
* Bring back `PYBIND11_CPP17` in determining `PYBIND11_ENABLE_TYPE_CASTER_ODR_GUARD`, to hopefully resolve most if not all of the many CI failures (89 failing, 32 successful: https://github.com/pybind/pybind11/runs/7430295771).
* Try another workaround for `__has_builtin`-related breakages (https://github.com/pybind/pybind11/runs/7430720321).
* Remove `defined(__has_builtin)` and subconditions.
* Update "known to not work" expectation in test and comment.
* `pytest.skip` `num_violations == 0` only `#ifdef __NO_INLINE__` (irrespective of the compiler)
* Systematically change all new `#ifdef` to `#if defined` (review suggestion).
* Bring back MSVC comment that got lost while experimenting.
* 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
* Undo the change in tests/test_exceptions.py
I turns out (I forgot) that PyPy segfaults in `test_flaky_exception_failure_point_init` already before the `MISMATCH` code path is reached:

* 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`.
* Add test_namespace_visibility
To probe environment/toolchain/platform-specific behavior under the exact same conditions as normal tests.
(An earlier version of this code was used to inform PR #4043.)
* Disable flake8 in ubench/holder_comparison_*.py, to suppress new & useless diagnostics.
* Disable namespace_visibility_1s.cpp (tosee if that resolves the MSVC and CUDA `test_cross_module_exception_translator` failures).
* Turn off flake8 completely for ubench (the Strip unnecessary `# noqa`s action un-helpfully removed the added noqa).
* Disable test_namespace_visibility completely. Just keep the two .cpp files, only setting the module docstring and doing nothing else.
* Rename test_namespace_visibility.py to test_exc_namespace_visibility.py, so that it is imported by pytest before test_exceptions.py
* Add `set_property(SOURCE namespace_visibility_1s.cpp PROPERTY LANGUAGE CUDA)`
* Add reference to PR #4054
* Complete the documentation (comments in test_exc_namespace_visibility.py).
* Rename namespace_visibility.h to namespace_visibility.inl, as suggested by @charlesbeattie

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

* Optimize error_string creation
* Fix typo

* Fix merge conflict error
* Abuse assignment operator
* Revert operator abuse
* 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.

Debian clang version 13.0.1-3+build2
Target: x86_64-pc-linux-gnu
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.

* 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.

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.

* 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.

* Copying original change from PR #3343, with extra line breaks to not run past 99 columns (our desired but currently not enforced limit).
* Add a test showing a flaw in make_key_iterator/make_value_iterator
If the iterator dereference operator returns a value rather than a
reference (and that pair also does not *contain* references),
make_key_iterator and make_value_iterator will return a reference to a
temporary, causing a segfault.
* Fix make_key_iterator/make_value_iterator for prvalue iterators
If an iterator returns a pair<T1, T2> rather than a reference to a pair
or a pair of references, make_key_iterator and make_value_iterator would
return a reference to a temporary, typically leading to a segfault. This
is because the value category of member access to a prvalue is an
xvalue, not a prvalue, so decltype produces an rvalue reference type.
Fix the type calculation to handle this case.
I also removed some decltype parentheses that weren't needed, either
because the expression isn't one of the special cases for decltype or
because decltype was only used for SFINAE. Hopefully that makes the code
a bit more readable.
Closes#3347
* Attempt a workaround for nvcc
* Add `.keys` and `.values` to bind_map
Both of these implement views (rather than just iterators), and `.items`
is also upgraded to a view. In practical terms, this allows a view to be
iterated multiple times and have its size taken, neither of which works
with an iterator.
The views implement `__len__`, `__iter__`, and the keys view implements
`__contains__`. Testing membership also works in item and value views
because Python falls back to iteration. This won't be optimal
for item values since it's linear rather than O(log n) or O(1), but I
didn't fancy trying to get all the corner cases to match Python
behaviour (tuple of wrong types, wrong length tuple, not a tuple etc).
Missing relative to Python dictionary views is `__reversed__` (only
added to Python in 3.8). Implementing that could break code that binds
custom map classes which don't provide `rbegin`/`rend` (at least without
doing clever things with SFINAE), so I've not tried.
The size increase on my system is 131072 bytes, which is rather large
(5%) but also suspiciously round (2^17) and makes me suspect some
quantisation effect.
* bind_map: support any object in __contains__
Add extra overload of `__contains__` (for both the map itself and
KeysView) which takes an arbitrary object and returns false.
* Take py::object by const reference in __contains__
To keep clang-tidy happy.
* Removing stray `py::` (detected via interactive testing in Google environment).

* Fix `pybind11::object::operator=` to be safe if `*this` is accessible from Python
* Add `custom_type_setup` attribute
This allows for custom modifications to the PyHeapTypeObject prior to
calling `PyType_Ready`. This may be used, for example, to define
`tp_traverse` and `tp_clear` functions.
* Add make_value_iterator (#3271)
* Add make_value_iterator
This is the counterpart to make_key_iterator, and will allow
implementing a `value` method in `bind_map` (although doing so is left
for a subsequent PR).
I made a few design changes to reduce copy-and-paste boilerplate.
Previously detail::iterator_state had a boolean template parameter to
indicate whether it was being used for make_iterator or
make_key_iterator. I replaced the boolean with a class that determines
how to dereference the iterator. This allows for a generic
implementation of `__next__`.
I also added the ValueType and Extra... parameters to the iterator_state
template args, because I think it was a bug that they were missing: if
make_iterator is called twice with different values of these, only the
first set has effect (because the state class is only registered once).
There is still a potential issue in that the *values* of the extra
arguments are latched on the first call, but since most policies are
empty classes this should be even less common.
* Add some remove_cv_t to appease clang-tidy
* Make iterator_access and friends take reference
For some reason I'd accidentally made it take a const value, which
caused some issues with third-party packages.
* Another attempt to remove remove_cv_t from iterators
Some of the return types were const (non-reference) types because of the
pecularities of decltype: `decltype((*it).first)` is the *declared* type
of the member of the pair, rather than the type of the expression. So if
the reference type of the iterator is `pair<const int, int> &`, then the
decltype is `const int`. Wrapping an extra set of parentheses to form
`decltype(((*it).first))` would instead give `const int &`.
This means that the existing make_key_iterator actually returns by value
from `__next__`, rather than by reference. Since for mapping types, keys
are always const, this probably hasn't been noticed, but it will affect
make_value_iterator if the Python code tries to mutate the returned
objects. I've changed things to use double parentheses so that
make_iterator, make_key_iterator and make_value_iterator should now all
return the reference type of the iterator. I'll still need to add a test
for that; for now I'm just checking whether I can keep Clang-Tidy happy.
* Add back some NOLINTNEXTLINE to appease Clang-Tidy
This is favoured over using remove_cv_t because in some cases a const
value return type is deliberate (particularly for Eigen).
* Add a unit test for iterator referencing
Ensure that make_iterator, make_key_iterator and make_value_iterator
return references to the container elements, rather than copies. The
test for make_key_iterator fails to compile on master, which gives me
confidence that this branch has fixed it.
* Make the iterator_access etc operator() const
I'm actually a little surprised it compiled at all given that the
operator() is called on a temporary, but I don't claim to fully
understand all the different value types in C++11.
* Attempt to work around compiler bugs
https://godbolt.org/ shows an example where ICC gets the wrong result
for a decltype used as the default for a template argument, and CI also
showed problems with PGI. This is a shot in the dark to see if it fixes
things.
* Make a test constructor explicit (Clang-Tidy)
* Fix unit test on GCC 4.8.5
It seems to require the arguments to the std::pair constructor to be
implicitly convertible to the types in the pair, rather than just
requiring is_constructible.
* Remove DOXYGEN_SHOULD_SKIP_THIS guards
Now that a complex decltype expression has been replaced by a simpler
nested type, I'm hoping Doxygen will be able to build it without issues.

* Eliminate duplicate TLS keys for loader_life_support stack
This revises the existing fix for
https://github.com/pybind/pybind11/issues/2765 in
https://github.com/pybind/pybind11/pull/3237 to reduce the amount of
TLS storage used.
The shared TLS key is stored in two different ways, depending on
`PYBIND11_INTERNALS_VERSION`. If `PYBIND11_INTERNALS_VERSION ==
4` (as is currently set), the TLS key is stored in the
`internal::shared_data` map to avoid breaking ABI compatibility. If
`PYBIND11_INTERNALS_VERSION > 4`, the TLS key is stored directly in
the `internals` struct.

* Fix thread safety for pybind11 loader_life_support
Fixes issue: https://github.com/pybind/pybind11/issues/2765
This converts the vector of PyObjects to either a single void* or
a per-thread void* depending on the WITH_THREAD define.
The new field is used by each thread to construct a stack
of loader_life_support frames that can extend the life of python
objects.
The pointer is updated when the loader_life_support object is allocated
(which happens before a call) as well as on release.
Each loader_life_support maintains a set of PyObject references
that need to be lifetime extended; this is done by storing them
in a c++ std::unordered_set and clearing the references when the
method completes.
