8f00d1eea0 fix: set __file__ on submodules (#5584) 
* fix: set __file__ on submodules

The docs state ['The caller is responsible for setting a `__file__` attribute'](https://docs.python.org/3/c-api/module.html), but we
were not doing that, which interferes with pickling objects in submodules using cloudpickle. Users previously had to set the `__file__` attributes manually,
such as in 1fbbe1632e/src/boost_histogram/histogram.py (L83-L90).

f365314ec0 Enable Conversions Between Native Python Enum Types and C++ Enums (#5555) 
* Apply smart_holder-branch-based PR #5280 on top of master.

* Add pytest.skip("GraalPy does not raise UnicodeDecodeError")

* Add `parent_scope` as first argument to `py::native_enum` ctor.

* Replace `operator+=` API with `.finalize()` API. The error messages still need cleanup.

* Resolve clang-tidy performance-unnecessary-value-param errors

* Rename (effectively) native_enum_add_to_parent() -> finalize()

* Update error message: pybind11::native_enum<...>("Fake", ...): MISSING .finalize()

* Pass py::module_ by reference to resolve clang-tidy errors (this is entirely inconsequential otherwise for all practical purposes).

* test_native_enum_correct_use_failure -> test_native_enum_missing_finalize_failure

* Add test_native_enum_double_finalize(), test_native_enum_value_after_finalize()

* Clean up public/protected API.

* [ci skip] Update the Enumerations section in classes.rst

* Rename `py::native_enum_kind` → `py::enum_kind` as suggested by gh-henryiii:

https://github.com/pybind/pybind11/pull/5555#issuecomment-2711672335

* Experiment: StrEnum

enum.StrEnum does not map to C++ enum:

* Remove StrEnum code.

* Make enum_kind::Enum the default kind.

* Catch redundant .export_values() calls.

* [ci skip] Add back original documentation for `py::enum_` under new advanced/deprecated.rst

* [ci skip] Add documentation for `py::enum_kind` and `py::detail::type_caster_enum_type_enabled`

* Rename `Type` to `EnumType` for readability.

* Eliminate py::enum_kind, use "enum.Enum", "enum.IntEnum" directly. This is still WIP.

* EXPERIMENTAL StrEnum code. To be removed.

* Remove experimental StrEnum code:

My judgement: Supporting StrEnum is maybe nice, but not very valuable. I don't think it is worth the extra C++ code.

A level of indirection would need to be managed, e.g.

    RED   ↔ Python "r" ↔ C++ 0
    Green ↔ Python "g" ↔ C++ 1

These mappings would need to be stored and processed.

* Add test with enum.IntFlag (no production code changes required).

* First import_or_getattr() implementation (dedicated tests are still missing).

* Fix import_or_getattr() implementation, add tests, fix clang-tidy errors.

* [ci skip] Update classes.rst: replace `py::enum_kind` with `native_type_name`

* For "constructor similar to that of enum.Enum" point to https://docs.python.org/3/howto/enum.html#functional-api, as suggested by gh-timohl (https://github.com/pybind/pybind11/pull/5555#discussion_r2009277507).

* Advertise Enum, IntEnum, Flag, IntFlags are compatible stdlib enum types in the documentation (as suggested by gh-timohl, https://github.com/pybind/pybind11/pull/5555#pullrequestreview-2708832587); add test for enum.Flag to ensure that is actually true.

974eba77a5 Change PYBIND11_MODULE to use multi-phase init (PEP 489) (#5574) 
* Change PYBIND11_MODULE to use multi-phase init

Use slots to specify advanced init options (currently just Py_GIL_NOT_USED).
Adds a new function `initialize_multiphase_module_def` to module_, similar to the existing (unchanged) create_extension_module.

* Avoid dynamic allocation and non-trivial destruction

... by using an std::array for the slots.

* Oops, stray cut and paste character

* Remove assignment from placement new, change size fo slots array

* style: pre-commit fixes

79be5c8316 test: Explicitly mark char as signed in dtype tests (#5545) 
When run on a platform where `char` is unsigned by default — which is
implementation-defined.

This explicitly uses `signed char` in two tests where the sign of the
char is important (though only `test_dtype_normalized_num` fails without
this change).

* Remove ubench/ directory.

* Remove include/pybind11/smart_holder.h

* [ci skip] smart_ptrs.rst updates [WIP/unfinished]

* [ci skip] smart_ptrs.rst updates continued; also updating classes.rst, advanced/classes.rst

* Remove README_smart_holder.rst

* Restore original README.rst from master

* [ci skip] Minimal change to README.rst, to leave a hint that this is pybind11v3

* [ci skip] Work in ChatGPT suggestions.

* Change macro name to PYBIND11_RUN_TESTING_WITH_SMART_HOLDER_AS_DEFAULT_BUT_NEVER_USE_IN_PRODUCTION_PLEASE

* Add a note pointing to the holder reinterpret_cast.

* Incorporate suggestion by @virtuald: https://github.com/pybind/pybind11/pull/5542#discussion_r1967000989

* Systematically change most py::class_ to py::classh under docs/

* Remove references to README_smart_holder.rst

This should have been part of commit eb550d03d3.

* [ci skip] Fix minor oversight (``class_`` -> ``py::class_``) noticed by chance.

* [ci skip] Resolve suggestion by @virtuald

* docs: focus on py::smart_holder instead of py::classh

Signed-off-by: Henry Schreiner <henryschreineriii@gmail.com>

* Restore minor general fixes that got lost when ac9d31e13f was reverted.

* Remove `- smart_holder` from list of branches in all .github/workflows

* Extend classh note to explain whitespace noise motivation.

* Suggest `py::smart_holder` for "most situations for safety"

* Add back PYBIND11_HAS_INTERNALS_WITH_SMART_HOLDER_SUPPORT

This define was
* introduced with https://github.com/pybind/pybind11/pull/5286
* removed with https://github.com/pybind/pybind11/pull/5531

It is has been in use here:
* f02a2b7653/pybind11_protobuf/native_proto_caster.h (L89-L101)

Currently pybind11 unit tests for the two holder caster backwards compatibility traits

* `copyable_holder_caster_shared_ptr_with_smart_holder_support_enabled`
* `move_only_holder_caster_unique_ptr_with_smart_holder_support_enabled`

are missing.

* Add py::trampoline_self_life_support to all trampoline examples under docs/.

Address suggestion by @timohl:

* https://github.com/pybind/pybind11/pull/5542#issuecomment-2686452062

Add to the "please think twice" note: the overhead for safety is likely in the noise.

Also fix a two-fold inconsistency introduced by revert-commit 1e646c91b4:

1.

py::trampoline_self_life_support is mentioned in a note, but is missing in the example right before.

2.

The section starting with

    To enable safely passing a ``std::unique_ptr`` to a trampoline object between

is obsolete.

* Fix whitespace accident (indentation) introduced with 1e646c91b4

Apparently the mis-indentation was introduced when resolving merge conflicts for what became 1e646c91b4

* WHITESPACE CHANGES ONLY in README.rst (list of people that made significant contributions)

* Add Ethan Steinberg to list of people that made significant contributions (for completeness, unrelated to smart_holder work).

* [ci skip] Add to list of people that made significant contributions: major and/or influential contributors to smart_holder branch

34a118fd36 Add release_gil_before_calling_cpp_dtor annotation for class_ (#5522) 
* Backport of https://github.com/google/pybind11clif/pull/30088 (main PR) and https://github.com/google/pybind11clif/pull/30092 (minor fixes).

Note for completeness:

These are identical to the current versions on the pybind11clif main branch (@ commit 4841661df5daf26ecdedaace54e64d0782e63f64):

* test_class_release_gil_before_calling_cpp_dtor.cpp
* test_class_release_gil_before_calling_cpp_dtor.py

* Fix potential data race in test_class_release_gil_before_calling_cpp_dtor.cpp

The original intent was to let the singleton leak, but making that tread-safe is slightly more involved than this solution. It's totally fine in this case if the RegistryType destructor runs on process teardown.
