Enable type-safe interoperability between different independent Python/C++ bindings systems. (#5296)
* `self.__cpp_transporter__()` proof of concept: Enable passing C++ pointers across extensions even if the `PYBIND11_INTERNALS_VERSION`s do not match.

* Include cleanup (mainly to resolve PyPy build failures).

* Fix clang-tidy errors.

* Resolve `error: extra

* factor out platform_abi_id.h from internals.h (no functional changes)

* factor out internals_version.h from internals.h (no functional changes)

* Update CMakeLists.txt, tests/extra_python_package/test_files.py

* Revert "factor out internals_version.h from internals.h (no functional changes)"

This reverts commit 3ccea8cd43.

* Remove internals_version.h from CMakeLists.txt, tests/extra_python_package/test_files.py

* `.__cpp_transporter__()` implementation: compare `pybind11_platform_abi_id`, `cpp_typeid_name`

* Add PremiumTraveler

* Rename test_cpp_transporter_traveler_type.h -> test_cpp_transporter_traveler_types.h

* Expand tests: `PremiumTraveler`, `get_points()`

* Shuffle order of tests (no real changes).

* Move `__cpp_transporter__` lambda to `py::cpp_transporter()` regular function.

* Use `type_caster_generic::load(self)` instead of `cast<T *>(self)`

* Pass `const std::type_info *` via `py::capsule` (instead of `cpp_typeid_name`).

* Make platform_abi_id.h completely stand-alone.

* rename exo_planet.cpp -> exo_planet_pybind11.cpp

* Add exo_planet_c_api.cpp (incomplete).

* Fix silly oversight (wrong filename in `#include`).

* Resolve clang-tidy errors:

```

```

* Implement exo_planet_c_api GetLuggage(), GetPoints()

* Move new code from test_cpp_transporter_traveler_bindings.h to pybind11/detail/type_caster_base.h, under the name `class_dunder_cpp_transporter()`

* Fix oversight.

* Unconditionally add `__cpp_transporter__` method to all `py::class_` objects, but do not include that magic method in docstring signatures.

* Back out pybind11/detail/platform_abi_id.h for now. Maximizing reusability can be handled separately, later.

* Small cleanup.

* Restore and add to `test_call_cpp_transporter_*()`

* Ensure https://github.com/pybind/pybind11/issues/3788 does not bite again.

* `class_dunder_cpp_transporter()`: replace `obj.cast<std::string>()` with `std::string(obj)`

* Add (simple) copyright notices in all newly added files.

* Globally replace cpp_transporter with cpp_conduit

* style: pre-commit fixes

* IWYU fixes

* Rename `class_dunder_cpp_conduit()` -> `cpp_conduit_method()`

* Change `pybind11_platform_abi_id`, `pointer_kind` argument types from `str` to `bytes`.

This avoids the unicode decode/encode roundtrips:

* More robust (no decode/encode errors).

* Minor runtime optimization.

* Systematically rename `cap_cpp_type_info` -> `cpp_type_info_capsule` (no functional changes).

* Systematically replace `cpp_type_info_capsule` `name`: `"const std::type_info *"` -> `typeid(std::type_info).name()` (this IS a functional change).

This provides an extra layer of protection against C++ ABI mismatches:

* The first and most important layer is that the `PYBIND11_PLATFORM_ABI_ID`s must match between extensions.

* The second layer is that the `typeid(std::type_info).name()`s must match between extensions.

* Fix sort order accident in tests/CMakeLists.txt

* Apply suggestions from code review

[smart_holder] Introduce PYBIND11_SMART_HOLDER_DISABLE option. (#5348)
* Step 1: Establish new `PYBIND11_SMART_HOLDER_ENABLED` macro, but only under include/pybind11/

At the stage `PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT` and `PYBIND11_SMART_HOLDER_ENABLED` are still equivalent.

* Systematically replace all `PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT` with `PYBIND11_SMART_HOLDER_ENABLED` under tests/ and ubench/

As at the previous stage, `PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT` and `PYBIND11_SMART_HOLDER_ENABLED` are still equivalent.

* Introduce `PYBIND11_SMART_HOLDER_DISABLE` option.

* `#ifdef` out entire `wrap()` function to avoid `unused-parameter` warning-as-error under macos-13

Replace all SMART_HOLDER_WIP comments with reminders, notes, or pointers. (#5336)
The SMART_HOLDER_WIP comments are mostly from 2021. In the meantime, the
smart_holder code was extremely thoroughly tested in the Google codebase
(production code). Additionally, testing via PyCLIF-pybind11 provided
thousands of diverse use cases that needed to satisfy many million unit tests
(the success rate was about 99.999%).

[smart_holder] Fix handling of const unique_ptr<T, D> & (do not disown). (#5332)
* Replace `unique_ptr_cref_roundtrip()` with `pass_unique_ptr_cref()`, `rtrn_unique_ptr_cref()` to make the current behavior obvious.

Make stl.h list|set|map_caster more user friendly. (#4686)
* Add `test_pass_std_vector_int()`, `test_pass_std_set_int()` in test_stl

* Change `list_caster` to also accept generator objects (`PyGen_Check(src.ptr()`).

Note for completeness: This is a more conservative change than https://github.com/google/pywrapcc/pull/30042

* Drop in (currently unpublished) PyCLIF code, use in `list_caster`, adjust tests.

* Use `PyObjectTypeIsConvertibleToStdSet()` in `set_caster`, adjust tests.

* Use `PyObjectTypeIsConvertibleToStdMap()` in `map_caster`, add tests.

* Simplify `list_caster` `load()` implementation, push str/bytes check into `PyObjectTypeIsConvertibleToStdVector()`.

* clang-tidy cleanup with a few extra `(... != 0)` to be more consistent.

* Also use `PyObjectTypeIsConvertibleToStdVector()` in `array_caster`.

* Update comment pointing to clif/python/runtime.cc (code is unchanged).

* Comprehensive test coverage, enhanced set_caster load implementation.

* Resolve clang-tidy eror.

* Add a long C++ comment explaining what led to the `PyObjectTypeIsConvertibleTo*()` implementations.

* Minor function name change in test.

* strcmp -> std::strcmp (thanks @Skylion007 for catching this)

* Add `PyCallable_Check(items)` in `PyObjectTypeIsConvertibleToStdMap()`

* Resolve clang-tidy error

[smart_holder] Bake smart_holder functionality into class_ and type_caster_base (#5257)
* 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).

feat: remove Python 3.7 support (#5191)
* First pass updating misc files, informed by https://github.com/pybind/pybind11/pull/5177/commits

* Remove jobs using silkeh/clang and gcc docker containers that come with Python 3.7

* Add silkeh/clang:17-bookworm

* Add job using GCC 7

* Revert "Add job using GCC 7"

This reverts commit 518515a761.

* Try running in ubuntu-18.04 container under ubuntu-latest (to get GCC 7)

* Fix `-` vs `:` mixup.

* This reverts commit b1c4304475.

Revert "Try running in ubuntu:18.04 container under ubuntu-latest (to get GCC 7)"

This reverts commit b203a294bb.

* `git grep 0x03080000` cleanup.

* `git grep -I -E '3\.7'` cleanup.

Removes two changes made under pybind/pybind11#3702

* Revert "`git grep -I -E '3\.7'` cleanup."

This reverts commit bb5b9d187b.

* Remove comments that are evidently incorrect:

```

* .github/workflows/configure.yml: Change from Python 3.7 to 3.8

* Misc cleanup pass

* Miscellaneous changes based on manual review of the `git grep` matches below:

```
git_grep_37_38.sh |& sort | uniq -c
```

With git_grep_37_38.sh:

```
set -x
git grep 0x0307
git grep 0x0308
git grep PY_MINOR_VERSION
git grep PYPY_VERSION
git grep -I -E '3\.7'
git grep -I -E '3\.8'

git grep -I -E '\(3, 8'
git grep -I -E '3[^A-Za-z0-9.]+7'

79fd12b8cc Add NOLINTNEXTLINE(bugprone-unused-return-value) in smart_holder_poc_test.cpp
Follow-on to https://github.com/pybind/pybind11/pull/5272 — clang-tidy upgrade (to version 18)

Fixes this error:

```
/__w/pybind11/pybind11/tests/pure_cpp/smart_holder_poc_test.cpp:167:12: error: the value returned by this function should not be disregarded; neglecting it may lead to errors [bugprone-unused-return-value,-warnings-as-errors]
  167 |     (void) new_owner.release(); // Manually verified: without this, clang++ -fsanitize=address
      |            ^~~~~~~~~~~~~~~~~~~
```

See also: https://clang.llvm.org/extra/clang-tidy/checks/bugprone/unused-return-value.html

Specifically there:

> std::unique_ptr::release(). Not using the return value can lead to resource leaks if the same pointer isn’t stored anywhere else. Often, ignoring the release() return value indicates that the programmer confused the function with reset().

I.e. the only way to tell clang-tidy that the smart_holder_poc_test.cpp is correct is to add the `NOLINT`.

clang-tidy upgrade (to version 18) (#5272)
* `container: silkeh/clang:18-bookworm` in .github/workflows/format.yml

* clang-tidy auto-fix (trivial, in test only)

* Disable `performance-enum-size` (noisy, low value)

* Temporarily turn off 3 diagnostics (to be tackled one-by-one).

* Add explicit `switch` `default` to resolve clang-tidy `bugprone-switch-missing-default-case`

Debian clang version 18.1.8 (++20240718080534+3b5b5c1ec4a3-1~exp1~20240718200641.143)
Target: x86_64-pc-linux-gnu

tests/test_numpy_dtypes.cpp:212:5: warning: switching on non-enum value without default case may not cover all cases [bugprone-switch-missing-default-case]

* Add clang-17 and clang-18 testing.

* Add `NOLINTNEXTLINE(clang-analyzer-optin.core.EnumCastOutOfRange)` in test_tagbased_polymorphic.cpp

Debian clang version 18.1.8 (++20240718080534+3b5b5c1ec4a3-1~exp1~20240718200641.143)

tests/test_tagbased_polymorphic.cpp:77:40: warning: The value '150' provided to the cast expression is not in the valid range of values for 'Kind' [clang-analyzer-optin.core.EnumCastOutOfRange]

* Fix inconsistent pybind11/eigen/tensor.h behavior:

This existing comment in pybind11/eigen/tensor.h

```
                // move, take_ownership don't make any sense for a ref/map:
```

is at odds with the `delete src;` three lines up.

In real-world client code `take_ownership` will not exist (unless the client code is untested and unused). I.e. the `delete` is essentially only useful to avoid leaks in the pybind11 unit tests.

While upgrading to clang-tidy 18, the warning below appeared. Apparently it is produced during LTO, and it appears difficult to suppress. Regardless, the best way to resolve this is to remove the `delete` and to simply make the test objects `static` in the unit test code.

Import additional test code originally added under PR #5213 (test_class_sh_property_bakein) (#5256)
Corresponding to PR #5213 commit 3406be6877

Reduced from use cases in the wild:

* `test_readonly_char6_member()`: 4410c44ae6/torch/csrc/cuda/Module.cpp (L961)

* `test_readonly_const_char_ptr_member()`: 862a439a84/include/permonst.h (L43)

Small cleanup/refactoring in support of PR #5213 (#5251)
* 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).
