* First draft a subinterpreter embedding API
* Move subinterpreter tests to their own file
* Migrate subinterpreter tests to use the new embedded class.
* Add a test for moving subinterpreters across threads for destruction
And find a better way to make that work.
* Code organization
* Add a test which shows demostrates how gil_scoped interacts with sub-interpreters
* Add documentation for embeded sub-interpreters
* Some additional docs work
* Add some convenience accessors
* Add some docs cross references
* Sync some things that were split out into #5665
* Update subinterpreter docs example to not use the CPython api
* Fix pip test
* style: pre-commit fixes
* Fix MSVC warnings
I am surprised other compilers allowed this code with a deleted move ctor.
* Add some sub-headings to the docs
* Oops, make_unique is C++14 so remove it from the tests.
* I think this fixes the EndInterpreter issues on all versions.
It just has to be ifdef'd because it is slightly broken on 3.12, working well on 3.13, and kind of crashy on 3.14beta. These two verion ifdefs solve all the issues.
* Add a note about exceptions.
They contain Python object references and acquire the GIL, that means they are a danger with subinterpreters!
* style: pre-commit fixes
* Add try/catch to docs examples to match the tips
* Python 3.12 is very picky about this first PyThreadState
Try special casing the destruction on the same thread.
* style: pre-commit fixes
* Missed a rename in a ifdef block
* I think this test is causing problems in 3.12, so try ifdefing it to see if the problems go away.
* style: pre-commit fixes
* Document the 3.12 constraints with a warning
* Apply suggestions from code review

* Remove sentence: Using self._pybind11_conduit_v1_() ... should keep extension compatibility.
This isn't true, because we also modernized `PYBIND11_PLATFORM_ABI_ID`
(which I believe was absolutely necessary). I think it'll be too complicated
to explain that here, and there is a mention in the Upgrade guide.

* Fix this embedded GIL test for free-threading
* Oops, need to use ptr() here
* This test created a subinterpreter when PYBIND11_SUBINTERPRETER_SUPPORT was off

The hang was a GIL issue between the subinterpreters during pybind11::exception::what().

Since we can avoid them by checking this atomic, the cmake config conditional shouldn't be necessary.
The slower path (with thread_locals and extra checks) only comes in when a second interpreter is actually instanciated.

* Replace `classh : class_` inhertance with `using`, as suggested by @henryiii
https://github.com/pybind/pybind11/pull/5542#issuecomment-2689034104
* Revert "Systematically change most py::class_ to py::classh under docs/"
This reverts commit ac9d31e13f.
* 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

* Sync `Py_TPFLAGS_MANAGED_DICT` for PyPy3.11 across the codebase
Adjust the `Py_TPFLAGS_MANAGED_DICT` logic in `include/pybind11/attr.h`
to match the one used in `include/pybind11/detail/class.h`.
This is a followup to #5508.
* Use a common `#define` for pre-`Py_TPFLAGS_MANAGED_DICT` Pythons
* style: pre-commit fixes

* Start pybind11v3
* Remove all code for PYBIND11_INTERNALS_VERSION 4 and 5
* Fix oversight: pybind11/_version.py needs to be updated as well.
* Add @pytest.mark.skipif("env.GRAALPY", reason="TODO debug segfault")
* 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.

* Remove some maybe-uninitialized warnings
In the Eigen matrix type_caster, resize the matrix instead of assigning with a new one when the matrix size needs to be adjusted.
This can remove lots of compiling warnings about "maybe-uninitialized".
* Revert "Remove some maybe-uninitialized warnings"
This reverts commit 7d5a9b41aa.
* Suppress `-Wmaybe-uninitialized` warning
