* Put bakein branch @ 18b72c0ffa on top of smart_holder branch:
Commands used:
```
git checkout bakein
git diff smart_holder > ~/zd
git checkout smart_holder
git checkout -b bakein_sh
patch -p 1 < ~/zd
git checkout smart_holder \
MANIFEST.in \
README.rst \
README_smart_holder.rst \
docs/advanced/smart_ptrs.rst \
ubench/holder_comparison.cpp \
ubench/holder_comparison.py \
ubench/holder_comparison_extract_sheet_data.py \
ubench/number_bucket.h \
ubench/python/number_bucket.clif
git add -A
```
* Add back README_smart_holder.rst in tests/extra_python_package/test_files.py
* Restore smart_holder_poc.h as-is on smart_holder branch (i.e. undo `PYBIND11_SMART_HOLDER_PADDING`, which was meant for stress-testing only).
* Insert `std::move()` as suggested by @laramiel
* `property_cpp_function_sh_*` named specializations, as suggested by @laramiel (https://github.com/pybind/pybind11/pull/5257#discussion_r1688346807)
* Call `property_cpp_function_classic` member functions, rather than inlining the implementations.
* Use `PYBIND11_HAVE_INTERNALS_WITH_SMART_HOLDER_SUPPORT` in holder_comparison.cpp (holder_comparison.py is NOT changed accordingly in this commit, i.e. can still only be run if the smart_holder functionality is available).
* Systematically rename `loaded_as` to `load_as` (`shared_ptr`, `unique_ptr`) as suggested by @laramiel
* Make change as suggested by @laramiel. This makes it much more obvious that the latest implementation of `smart_holder_from_unique_ptr()` accepts all existing `return_value_policy` enum values except `copy`.
* Resolve `BAKEIN_WIP: Rewrite comment.` for `property_cpp_function_*` specializations.
* Resolve `BAKEIN_WIP: Add comment to explain: This is meant for stress-testing only.`
* Resolve all remaining BAKEIN_WIP (in pybind11/cast.h).
Leave only two pairs of SMART_HOLDER_BAKEIN_FOLLOW_ON comments: refactoring of copyable_holder_caster, move_only_holder_caster. This is best left until after the smart_holder branch is merged into the master branch.
* Remove obsolete `using holder_type = smart_holder;` in `load_helper`
* Add SMART_HOLDER_BAKEIN_FOLLOW_ON comment for `internals::default_holder`
* README_smart_holder.rst update (line count reduced from 356 to 123).
* Factor out detail/value_and_holder.h (from detail/type_caster_base.h)
This is in support of PR #5213:
* trampoline_self_life_support.h depends on value_and_holder.h
* type_caster_base.h depends on trampoline_self_life_support.h
* Fix a minor and inconsequential inconsistency in `copyable_holder_caster`: the correct `load_value()` return type is `void` (as defined in `type_caster_generic`)
For easy future reference, this is the long-standing inconsistency:
* dbf848aff7/include/pybind11/detail/type_caster_base.h (L634)
* dbf848aff7/include/pybind11/cast.h (L797)
Noticed in passing while working on PR #5213.
* Add `DANGER ZONE` comment in detail/init.h, similar to a comment added on the smart_holder branch (all the way back in 2021).
* fix(cmake): do not use Python::Interpreter when cross-compiling
* chore: apply cmake-format to pybind11NewTools.cmake
* fix(cmake): do not look for Python Interpreter component when cross-compiling
* feat(cmake): guess Python extension suffix
* fix: add pybind11GuessPythonExtSuffix.cmake to packaging test
* Use PYBIND11_CROSSCOMPILING instead of CMAKE_CROSSCOMPILING
* refactor: require PYBIND11_USE_CROSSCOMPILING

* 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
* 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.
```
test_type_caster_pyobject_ptr.cpp:8:23: error: variable templates only available with ‘-std=c++14’ or ‘-std=gnu++14’ [-Werror]
8 | static constexpr bool is_same_ignoring_cvref = std::is_same<detail::remove_cvref_t<T>, U>::value;
| ^~~~~~~~~~~~~~~~~~~~~~
```
* 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.

* Replace C++17 syntax. Compiles with Debian clang 13 C++11 mode, but fails to link. Trying GitHub Actions anyway to see if there are any platforms that support https://en.cppreference.com/w/cpp/language/tu_local before C++20. Note that Debian clang 13 C++17 works locally.
* Show C++ version along with ODR VIOLATION DETECTED message.
* Add source_file_line_basename()
* Introduce PYBIND11_TYPE_CASTER_ODR_GUARD_ON (but not set automatically).
* Minor cleanup.
* Set PYBIND11_TYPE_CASTER_ODR_GUARD_ON automatically.
* Resolve clang-tidy error.
* Compatibility with old compilers.
* Fix off-by-one in source_file_line_basename()
* Report PYBIND11_INTERNALS_ID & C++ Version from pytest_configure()
* Restore use of PYBIND11_WERROR
* Move cpp_version_in_use() from cast.h to pybind11_tests.cpp
* define PYBIND11_DETAIL_ODR_GUARD_IMPL_THROW_DISABLED true in test_odr_guard_1,2.cpp
* IWYU cleanup of detail/type_caster_odr_guard.h
* Replace `throw err;` to resolve clang-tidy error.
* Add new header filename to CMakeLists.txt, test_files.py
* Experiment: Try any C++17 compiler.
* Fix ifdef for pragma GCC diagnostic.
* type_caster_odr_guard_impl() cleanup
* Move type_caster_odr_guard to type_caster_odr_guard.h
* Rename test_odr_guard* to test_type_caster_odr_guard*
* Remove comments that are (now) more distracting than helpful.
* 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:

* Eliminate need for `PYBIND11_DETAIL_TYPE_CASTER_ACCESS_TRANSLATION_UNIT_LOCAL` macro.
Copying code first developed by @amauryfa. I tried this at an earlier stage, but by itself this was insufficient. In the meantime I added in the TU-local mechanisms: trying again.

* Add new test_descr_src_loc & and fix descr.h `concat()` `src_loc` bug discovered while working on the test.
* Some more work on source code comments.
* 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

* 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.

* Splitting out pybind11/stl/filesystem.h.
To solve breakages like: https://github.com/deepmind/open_spiel/runs/2999582108
Mostly following the suggestion here: https://github.com/pybind/pybind11/pull/2730#issuecomment-750507575
Except using pybind11/stl/filesystem.h instead of pybind11/stlfs.h, as decided via chat.
stl.h restored to the exact state before merging PR #2730 via:
```
git checkout 733f8de24f stl.h
```
* Properly including new stl subdirectory in pip wheel config.
This now passes interactively:
```
pytest tests/extra_python_package/
```
* iwyu cleanup.
iwyuh.py -c -std=c++17 -DPYBIND11_TEST_BOOST -Ipybind11/include -I/usr/include/python3.9 -I/usr/include/eigen3 include/pybind11/stl/filesystem.h
* Adding PYBIND11_HAS_FILESYSTEM_IS_OPTIONAL.
* Eliminating else after return.
* Using new smart_holder::reclaim_disowned in smart_holder_type_caster for unique_ptr.
* Systematically renaming was_disowned to is_disowned (because disowning is now reversible: reclaim_disowned).
* Systematically renaming virtual_overrider_self_life_support to trampoline_self_life_support (to reuse existing terminology instead of introducing new one).
* Systematically renaming test_class_sh_with_alias to test_class_sh_trampoline_basic.
* Adding a Trampolines and std::unique_ptr section to README_smart_holder.rst.
* MSVC compatibility.
* Adaption of PyCLIF virtual_py_cpp_mix test.
* Removing ValueError: Ownership of instance with virtual overrides in Python cannot be transferred to C++. TODO: static_assert alias class needs to inherit from virtual_overrider_self_life_support.
* Bringing back ValueError: "... instance cannot safely be transferred to C++.", but based on dynamic_cast<AliasType>.
* Fixing oversight: adding test_class_sh_virtual_py_cpp_mix.cpp to cmake file.
* clang <= 3.6 compatibility.
* Fixing oversight: dynamic_raw_ptr_cast_if_possible needs special handling for To = void. Adding corresponding missing test in test_class_sh_virtual_py_cpp_mix. Moving dynamic_raw_ptr_cast_if_possible to separate header.
* Changing py::detail::virtual_overrider_self_life_support to py::virtual_overrider_self_life_support.
