* 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:

Open question, with respect to the original code:
76a160070b/include/pybind11/pybind11.h (L1510)
To me it looks like the exact situation marked as `std::shared_ptr<Good> gp1 = not_so_good.getptr();` here: https://en.cppreference.com/w/cpp/memory/enable_shared_from_this
The comment there is: `// undefined behavior (until C++17) and std::bad_weak_ptr thrown (since C++17)`
Does the existing code have UB pre C++17?
I'll leave handling of enable_shared_from_this for later, as the need arises.
* Cosmetical change around helper functions.
* Using type_caster_base<mpty>::src_and_type directly, removing copy. Also renaming one cast to cast_const_raw_ptr, for clarity.
* Fixing clang-format oversight.
* Using factored-out make_constructor (PR #2798), removing duplicate code.
* Inserting additional assert to ensure a returned unique_ptr is always a new Python instance.
* Adding minor comment (change to internals needed to distinguish uninitialized/disowned in error message).
* Factoring out find_existing_python_instance().
* Moving factored-out make_constructor to test_classh_wip.cpp, restoring previous version of cast.h. This is currently the most practical approach. See PR #2798 for background.
* Copying classh type_casters from test_classh_wip.cpp UNMODIFIED, as a baseline for generalizing the code.
* Using pybind11/detail/classh_type_casters.h from test_classh_wip.cpp.
* Adding & using PYBIND11_CLASSH_TYPE_CASTERS define.
* Adding test_classh_inheritance, currently failing (passes with class_).
* Removing .clang-format before git rebase master (where the file was added).
* Bringing back .clang-format, the previous rm was a bad idea.
* Folding in modified_type_caster_generic_load_impl, just enough to pass test_class_wip. test_classh_inheritance is still failing, but with a different error: [RuntimeError: Incompatible type (as_raw_ptr_unowned).]
* Minimal changes needed to pass test_classh_inheritance.
* First pass adjusting try_implicit_casts and try_load_foreign_module_local to capture loaded_v_h, but untested and guarded with pybind11_failure("Untested"). This was done mainly to determine general feasibility. Note the TODO in pybind11.h, where type_caster_generic::local_load is currently hard-coded. test_classh_wip and test_classh_inheritance still pass, as before.
* Decoupling generic_type from type_caster_generic.
* Changes and tests covering classh_type_casters try_implicit_casts.
* Minimal test covering classh_type_casters load_impl Case 2b.
* Removing stray isinstance<T>(src): it interferes with the py::module_local feature. Adding missing #includes.
* Tests for classh py::module_local() feature.
* Pure renaming of function names in test_classh_inheritance, similar to the systematic approach used in test_class_wip. NO functional changes.
* Pure renaming of function and variable names, for better generalization when convoluting with inheritance. NO functional changes.
* Adopting systematic naming scheme from test_classh_wip. NO functional changes.
* Moving const after type name, for functions that cover a systematic scheme. NO functional changes.
* Adding smart_holder_type_caster_load::loaded_as_shared_ptr, currently bypassing smart_holder shared_ptr tracking completely, but the tests pass and are sanitizer clean.
* Removing rtti_held from smart_holder. See updated comment.
* Cleaning up loaded_as_raw_ptr_unowned, loaded_as_shared_ptr.
* Factoring out convert_type and folding into loaded_as_unique_ptr.
* Folding convert_type into lvalue_ref and rvalue_ref paths. Some smart_holder_type_caster_load cleanup.
* Using unique_ptr in local_load to replace static variable. Also adding local_load_safety_guard.
* Converting test_unique_ptr_member to using classh: fully working, ASAN, MSAN, UBSAN clean.
* Removing debugging comments (GET_STACK, GET_INT_STACK). cast.h is identical to current master again, pybind11.h only has the generic_type::initialize(..., &type_caster_generic::local_load) change.
* Purging obsolete pybind11/vptr_holder.h and associated test.
* Moving several tests to github.com/rwgk/rwgk_tbx/tree/main/pybind11_tests
a2c2f88174
These tests are from experimenting, and for demonstrating UB in pybind11 multiple inheritance handling ("first_base"), to be fixed later.
* Adding py::smart_holder support to py::class_, purging py::classh completely.
* Renaming files in include directory, creating pybind11/smart_holder.h.
* Renaming all "classh" to "smart_holder" in pybind11/detail/smart_holder_type_casters.h.
The user-facing macro is now PYBIND11_SMART_HOLDER_TYPE_CASTERS.
* Systematically renaming tests to use "class_sh" in the name.
* Renaming test_type_caster_bare_interface_demo to test_type_caster_bare_interface.
* Renaming new tests/core subdirectory to tests/pure_cpp.
* Adding new tests to CMake config, resetting CI config.
* Changing CMake file so that test_class_sh_module_local.py actually runs.
* clang-tidy fixes.
* 32-bit compatibility.
* Reusing type_caster_base make_copy_constructor, make_move_constructor with a trick.
* CMake COMPARE NATURAL is not available with older versions.
* Adding copyright notices to new header files.
* Explicitly define copy/move constructors/assignments.
* Adding new header files to tests/extra_python_package/test_files.py.
* Adding tests/pure_cpp/CMakeLists.txt.
* Making use of the new find_existing_python_instance() function factored out with PR #2822.
* Moving define PYBIND11_SMART_HOLDER_TYPE_CASTERS(T) down in the file. NO functional changes. Preparation for follow-up work (to keep that diff smaller).
* Reintroducing py::classh, this time as a simple alias for py::class_<U, py::smart_holder>.
* Replacing detail::is_smart_holder<H> in cast.h with detail::is_smart_holder_type_caster<T>.
Moving get_local_load_function_ptr, init_instance_for_type to smart_holder_type_caster_class_hooks.
Expanding static_assert in py::type::handle_of<> to accommodate smart_holder_type_casters.
* Fixing oversight.
* Adding classu alias for class_<U, std::unique_ptr<U>>.
* Giving up on idea to use legacy init_instance only if is_base_of<type_caster_generic, type_caster<T>. There are use cases in the wild that define both a custom type_caster and class_.
* Removing test_type_caster_bare_interface, which was moved to the separate PR #2834.
* Moving up is_smart_holder_type_caster, to also use in cast_is_temporary_value_reference.
* Adding smart_holder_type_casters for unique_ptr with custom deleter. SEVERE CODE DUPLICATION. This commit is to establish a baseline for consolidating the unique_ptr code.
* Unification of unique_ptr, unique_ptr_with_deleter code in smart_holder_poc.h. Leads to more fitting error messages. Enables use of unique_ptr<T, D> smart_holder_type_casters also for unique_ptr<T>.
* Copying files as-is from branch test_unique_ptr_member (PR #2672).
* Adding comment, simplifying naming, cmake addition.
* Introducing PYBIND11_USE_SMART_HOLDER_AS_DEFAULT macro (tested only undefined; there are many errors with the macro defined).
* Removing test_type_caster_bare_interface, which was moved to the separate PR #2834.
* Fixing oversight introduced with commit 95425f13d6.
* Setting record.default_holder correctly for PYBIND11_USE_SMART_HOLDER_AS_DEFAULT.
With this test_class.cpp builds and even mostly runs, except
`test_multiple_instances_with_same_pointer`, which segfaults because it is
using a `unique_ptr` holder but `smart_holder` `type_caster`.
Also adding `static_assert`s to generate build errors for such situations,
but guarding with `#if 0` to first pivot to test_factory_constructors.cpp.
* Fixing up cast.h and smart_holder.h after rebase.
* Removing detail/smart_holder_type_casters.h in separate commit.
* Commenting out const in def_buffer(... const). With this, test_buffers builds and runs with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT. Explanation why the const needs to be removed, or fix elsewhere, is still needed, but left for later.
* Adding test_class_sh_factory_constructors, reproducing test_factory_constructors failure. Using py::class_ in this commit, to be changed to py::classh for debugging.
* Removing include/pybind11/detail/smart_holder_type_casters.h from CMakeLists.txt, test_files.py (since it does not exist in this branch).
* Adding // DANGER ZONE reminders.
* Converting as many py::class_ to py::classh as possible, not breaking tests.
* Adding initimpl::construct() overloads, resulting in test_class_sh_factory_constructors feature parity for py::class_ and py::classh.
* Adding enable_if !is_smart_holder_type_caster to existing initimpl::construct(). With this test_factory_constructors.cpp builds with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT.
* Disabling shared_ptr&, shared_ptr* tests when building with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT for now, pending work on smart_holder_type_caster<shared_ptr>.
* Factoring out struct and class definitions into anonymous namespace. Preparation for building with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT.
* Simplifying from_unique_ptr(): typename D = std::default_delete<T> is not needed. Factoring out is_std_default_delete<T>() for consistentcy between ensure_compatible_rtti_uqp_del() and from_unique_ptr().
* Introducing PYBIND11_SMART_POINTER_HOLDER_TYPE_CASTERS. Using it in test_smart_ptr.cpp. With this test_smart_ptr builds with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT and all but one test run successfully.
* Introducing 1. type_caster_for_class_, used in PYBIND11_MAKE_OPAQUE, and 2. default_holder_type, used in stl_bind.h.
* Using __VA_ARGS__ in PYBIND11_SMART_POINTER_HOLDER_TYPE_CASTERS.
* Replacing condense_for_macro with much simpler approach.
* Softening static_assert, to only check specifically that smart_holder is not mixed with type_caster_base, and unique_ptr/shared_ptr holders are not mixed with smart_holder_type_casters.
* Adding PYBIND11_SMART_POINTER_HOLDER_TYPE_CASTERS in test_class.cpp (with this all but one test succeed with PYBIND11_USE_SMART_HOLDER_AS_DEFAULT).
* Adding remaining PYBIND11_SMART_POINTER_HOLDER_TYPE_CASTERS. static_assert for "necessary conditions" for both types of default holder, static_assert for "strict conditions" guarded by new PYBIND11_STRICT_ASSERTS_CLASS_HOLDER_VS_TYPE_CASTER_MIX. All tests build & run as before with unique_ptr as the default holder, all tests build for smart_holder as the default holder, even with the strict static_assert.
* Introducing check_is_smart_holder_type_caster() function for runtime check, and reinterpreting record.default_holder as "uses_unique_ptr_holder". With this test_smart_ptr succeeds. (All 42 tests build, 35 tests succeed, 5 run but have some failures, 2 segfault.)
* Bug fix: Adding have_value() to smart_holder_type_caster_load. With this test_builtin_casters succeeds. (All 42 tests build, 36 tests succeed, 5 run but have some failures, 1 segfault.)
* Adding unowned_void_ptr_from_direct_conversion to modified_type_caster_generic_load_impl. This fixes the last remaining segfault (test_numpy_dtypes). New stats for all tests combined: 12 failed, 458 passed.
* Adding "Lazy allocation for unallocated values" (for old-style __init__) into load_value_and_holder. Deferring destruction of disowned holder until clear_instance, to remain inspectable for "uninitialized" or "disowned" detection. New stats for all tests combined: 5 failed, 465 passed.
* Changing std::shared_ptr pointer/reference to const pointer/reference. New stats for all tests combined: 4 failed, 466 passed.
* Adding return_value_policy::move to permissible policies for unique_ptr returns. New stats for all tests combined: 3 failed, 467 passed.
* Overlooked flake8 fixes.
* Manipulating failing ConstructorStats test to pass, to be able to run all tests with ASAN.
This version of the code is ASAN clean with unique_ptr or smart_holder as the default.
This change needs to be reverted after adopting the existing move-only-if-refcount-is-1
logic used by type_caster_base.
* Adding copy constructor and move constructor tracking to atyp. Preparation for a follow-up change in smart_holder_type_caster, to make this test sensitive to the changing behavior.
[skip ci]
* Removing `operator T&&() &&` from smart_holder_type_caster, for compatibility with the behavior of type_caster_base. Enables reverting 2 of 3 test manipulations applied under commit 249df7cbdb. The manipulation in test_factory_constructors.py is NOT reverted in this commit.
[skip ci]
* Fixing unfortunate editing mishap. This reverts the last remaining test manipulation in commit 249df7cbdb and makes all existing unit tests pass with smart_holder as default holder.
* GitHub CI clang-tidy fixes.
* Adding messages to terse `static_assert`s, for pre-C++17 compatibility.
* Using @pytest.mark.parametrize to run each assert separately (to see all errors, not just the first).
* Systematically removing _atyp from function names, to make the test code simpler.
* Using re.match to accommodate variable number of intermediate MvCtor.
* Also removing `operator T()` from smart_holder_type_caster, to fix gcc compilation errors. The only loss is pass_rref in test_class_sh_basic.
* Systematically replacing `detail::enable_if_t<...smart_holder...>` with `typename std::enable_if<...smart_holder...>::type`. Attempt to work around MSVC 2015 issues, to be tested via GitHub CI. The idea for this change originates from this comment: https://github.com/pybind/pybind11/issues/1616#issuecomment-444536813
* Importing re before pytest after observing a PyPy CI flake when importing pytest first.
* Copying MSVC 2015 compatibility change from branch pr2672_use_smart_holder_as_default.
* Introducing is_smart_holder_type_caster_base_tag, to keep smart_holder code more disconnected.
* Working around MSVC 2015 bug.
* Expanding comment for MSVC 2015 workaround.
* Systematically changing std::enable_if back to detail::enable_if_t, effectively reverting commit 5d4b6890a3.
* Removing unused smart_holder_type_caster_load::loaded_as_rvalue_ref (it was an oversight that it was not removed with commit 23036a45eb).
* Removing py::classu, because it does not seem useful enough.
* Reverting commit 6349531306 by un-commenting `const` in `def_buffer(...)`. To make this possible, `operator T const&` and `operator T const*` in `smart_holder_type_caster` need to be marked as `const` member functions.
* Adding construct() overloads for constructing smart_holder from alias unique_ptr, shared_ptr returns.
* Adding test_class_sh_factory_constructors.cpp to tests/CMakeLists.txt (fixes oversight, this should have been added long before).
* Compatibility with old clang versions (clang 3.6, 3.7 C++11).
* Cleaning up changes to existing unit tests.
* Systematically adding SMART_HOLDER_WIP tag. Removing minor UNTESTED tags (only the throw are not actually exercised, investing time there has a high cost but very little benefit).
* Splitting out smart_holder_type_casters again, into new detail/smart_holder_type_casters_inline_include.h.
* Splitting out smart_holder_init_inline_include.h.
* Adding additional new include files to CMakeLists.txt, tests/extra_python_package/test_files.py.
* clang-format cleanup of most smart_holder code.
* Adding source code comments in response to review.
* Simple micro-benchmark ("ubench") comparing runtime performance for several holders.
Tested using github.com/rwgk/pybind11_scons and Google-internal build system.
Sorry, no cmake support at the moment.

CI: Intel ICC with C++17
docs: pybind11/numpy.h does not require numpy at build time. (#2720)
This is nice enough to be mentioned explicitly in the docs.
docs: Update warning about Python 3.9.0 UB, now that 3.9.1 has been released (#2719)
Adjusting `type_caster<std::reference_wrapper<T>>` to support const/non-const propagation in `cast_op`. (#2705)
* Allow type_caster of std::reference_wrapper<T> to be the same as a native reference.
Before, both std::reference_wrapper<T> and std::reference_wrapper<const T> would
invoke cast_op<type>. This doesn't allow the type_caster<> specialization for T
to distinguish reference_wrapper types from value types.
After, the type_caster<> specialization invokes cast_op<type&>, which allows
reference_wrapper to behave in the same way as a native reference type.
* Add tests/examples for std::reference_wrapper<const T>
* Add tests which use mutable/immutable variants
This test is a chimera; it blends the pybind11 casters with a custom
pytype implementation that supports immutable and mutable calls.
In order to detect the immutable/mutable state, the cast_op needs
to propagate it, even through e.g. std::reference<const T>
Note: This is still a work in progress; some things are crashing,
which likely means that I have a refcounting bug or something else
missing.
* Add/finish tests that distinguish const& from &
Fixes the bugs in my custom python type implementation,
demonstrate test that requires const& and reference_wrapper<const T>
being treated differently from Non-const.
* Add passing a const to non-const method.
* Demonstrate non-const conversion of reference_wrapper in tests.
Apply formatting presubmit check.
* Fix build errors from presubmit checks.
* Try and fix a few more CI errors
* More CI fixes.
* More CI fixups.
* Try and get PyPy to work.
* Additional minor fixups. Getting close to CI green.
* More ci fixes?
* fix clang-tidy warnings from presubmit
* fix more clang-tidy warnings
* minor comment and consistency cleanups
* PyDECREF -> Py_DECREF
* copy/move constructors
* Resolve codereview comments
* more review comment fixes
* review comments: remove spurious &
* Make the test fail even when the static_assert is commented out.
This expands the test_freezable_type_caster a bit by:
1/ adding accessors .is_immutable and .addr to compare identity
from python.
2/ Changing the default cast_op of the type_caster<> specialization
to return a non-const value. In normal codepaths this is a reasonable
default.
3/ adding roundtrip variants to exercise the by reference, by pointer
and by reference_wrapper in all call paths. In conjunction with 2/, this
demonstrates the failure case of the existing std::reference_wrpper conversion,
which now loses const in a similar way that happens when using the default cast_op_type<>.
* apply presubmit formatting
* Revert inclusion of test_freezable_type_caster
There's some concern that this test is a bit unwieldly because of the use
of the raw <Python.h> functions. Removing for now.
* Add a test that validates const references propagation.
This test verifies that cast_op may be used to correctly detect
const reference types when used with std::reference_wrapper.
* mend
* Review comments based changes.
1. std::add_lvalue_reference<type> -> type&
2. Simplify the test a little more; we're never returning the ConstRefCaster
type so the class_ definition can be removed.
* formatted files again.
* Move const_ref_caster test to builtin_casters
* Review comments: use cast_op and adjust some comments.
* Simplify ConstRefCasted test
I like this version better as it moves the assertion that matters
back into python.

ICC CI: Downgrade pytest
pytest 6 does not capture the `discard_as_unraisable` stderr and
just writes a warning with its content instead.
