* Commenting out pragmas as an experiment to reproduce previous observation.
* Removing all (newly added, but already commented-out) pragma code, adding HINT use -isystem (as cmake does).

* Extra parentheses (almost all compilers failed without these).
* Removing MSVC C4996 from pragma block at the top of pybind11.h
* localtime_thread_safe, PYBIND11_COMPAT_STRDUP
* Adding #include <ctime> (attempt to fix MSVC 2015, 2017 errors).
* Create a module_internals struct
Since we now have two things that are going to be module local, it felt
correct to add a struct to manage them.
* Add local exception translators
These are added via the register_local_exception_translator function
and are then applied before the global translators
* Add unit tests to show the local exception translator works
* Fix a bug in the unit test with the string value of KeyError
* Fix a formatting issue
* Rename registered_local_types_cpp()
Rename it to get_registered_local_types_cpp() to disambiguate from the
new member of module_internals
* Add additional comments to new local exception code path
* Add a register_local_exception function
* Add additional unit tests for register_local_exception
* Use get_local_internals like get_internals
* Update documentation for new local exception feature

* Manually moving `// NOLINT` comments so that clang-format does not move them to the wrong places.

* 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.
* Unify cast_error message thrown by [simple|unpacking]_collector
simple_collector and unpacking_collector throw different error messages
when the casting of an argument failed: While the former mentions make_tuple(),
the latter emphasises the call argument (and its name/position).
* Consolidating "Unable to convert call argument" error reporting code to guarantee uniformity.

CAVEAT: The fix is NOT covered by pybind11 unit tests.
Now also passes the open_spiel iterated_prisoners_dilemma_test ASAN clean, in addition to all pybind11 and PyCLIF unit tests.
The problem was that calling `std::shared_ptr<void>::reset()` with a `void` pointer cannot possibly update the `shared_from_this` `weak_ptr`.
The solution is to store a `shd_ptr_reset` function pointer in `guarded_deleter` (similar in idea to the stored function pointer for calling `delete`).
This commit still includes all debugging code, i.e. is "dirty". The code will be cleaned up after the GitHub CI is fully successful.
* Add const T to docstring generation.
* Change order.
* See if existing test triggers for a const type.
* Add tests.
* Fix test.
* Remove experiment.
* Reformat.
* More tests, checks run.
* Adding `test_fmt_desc_` prefix to new test functions.
* Using pytest.mark.parametrize to 1. condense test; 2. exercise all functions even if one fails; 3. be less platform-specific (e.g. C++ float is not necessarily float32).

* Drop constraints on casting of std::shared_ptr
std::shared_ptrs can be shared across python and C++ by design.
* Correctly report casting error
It is important to return an empty handle.
Simply returning None, would skip the error handling in
simple_collector / unpacking_collector, although a python exception is set.
A function call would then be processed with a (wrong) None argument!
* Return None for nullptr
* Revert "Drop constraints on casting of std::shared_ptr"
This reverts commit 7cf53ae8b4.
* Crash when printing Unicode to redirected cout
Add failing tests
* Fix Unicode crashes redirected cout
* pythonbuf::utf8_remainder check end iterator
* Remove trailing whitespace and formatting iostream
* Avoid buffer overflow if ostream redirect races
This doesn't solve the actual race, but at least it now has a much lower
probability of reading past the end of the buffer even when data races
do occur.
* Bug fix: adding back `!is_alias<Class>(ptr)` that were accidentally omitted.
* Introducing PYBIND11_SH_AVL, PYBIND11_SH_DEF macros. Applying PYBIND11_SH_DEF to test_factory_constructors.py to complete test coverage.
* Using PYBIND11_SH_DEF in test_methods_and_attributes.cpp, for more complete test coverage.
* Using PYBIND11_SH_DEF in test_multiple_inheritance.cpp, for more complete test coverage.
* Cleaning up test_classh_mock.cpp.
* Better explanations for PYBIND11_SH_AVL, PYBIND11_SH_DEF.
* Disabling 3.10-dev builds.
When the user defines _GLIBCXX_USE_CXX11_ABI=0 to force the pre-c++11 ABI, numpy.h assumes that is_trivially_copyable is available.
It is not necessarily the case. This patch uses clang's feature detection instead.
The workaround is for certain libstdc++ versions, so the test should target these particular versions.
* 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.
* Porting subset of absltest code from reproducer provided by @elkhrt. Baseline for debugging ASAN heap-use-after-free.
* Moving Py_DECREF to resolve ASAN heap-use-after-free failure.
* Fixing trivial formatting issue.
* Workaround for clang 3.6 and 3.7.
* Adding PyGILState_Check() in object_api<>::operator().
* Enabling PyGILState_Check() for Python >= 3.6 only.
Possibly, this explains why PyGILState_Check() cannot safely be used with Python 3.4 and 3.5:
https://github.com/python/cpython/pull/10267#issuecomment-434881587
* Adding simple micro benchmark.
* Reducing test time to minimum (purely for coverage, not for accurate results).
* Fixing silly oversight.
* Minor code organization improvement in test.
* Adding example runtimes.
* Removing capsys (just run with `-k test_callback_num_times -s` and using `.format()`.
* 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.
* Initial version of virtual_overrider_self_life_support (enables safely passing unique_ptr to C++).
* Clang 3.6, 3.7 compatibility.
* Adding missing default constructor.
* Restoring test for exception for the case that virtual_overrider_self_life_support is not used.
* Fixing oversight: Adding missing holder().ensure_was_not_disowned().
* Adding unit tests for new `struct smart_holder` member functions.
* Moving virtual_overrider_self_life_support to separate include file, with iwyu cleanup.
* Use correct duration representation when casting from datetime.timdelta to std::chrono::duration
* When asserting datetime/timedelta/date/time we can equality-compare whole objects
* shared_ptr<bool> vptr_deleter_armed_flag_ptr (instead of unique_ptr), to fix heap-use-after-free bug.
* Fixing generated by some compilers in the pybind11 CI suite.
* Adding test_unique_ptr_member (for desired PyCLIF behavior).

* Adding unique_ptr<mpty>, unique_ptr<mpty const> casters.
* Pure copy of `class class_` implementation in pybind11.h (master commit 98f1bbb800).

* Fixing oversight (discovered by flake8).
* flake8 cleanup

* static cast handle for rtrn_cptr works by simply dropping in code from type_caster_base (marked with comments).
* static cast handle for rtrn_cref works by simply dropping in code from type_caster_base (marked with comments). rtrn_mref and rtrn_mptr work via const_cast (to add const).
* static cast handle for rtrn_valu works by simply dropping in code from type_caster_base (marked with comments). rtrn_rref raises a RuntimeError, to be investigated.

* Making test_type_caster_bare_interface_demo.cpp slightly more realistic, ASAN, MSAN, UBSAN clean.
* Calling deregister_instance after disowning via unique_ptr.
* Removing enable_shared_from_this stub, simplifying existing code, clang-format.
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.

* Always call PyNumber_Index when casting from Python to a C++ integral type, also pre-3.8
* Fixed on PyPy
* Simplify use of PyNumber_Index, following @rwgk's idea, and ignore warnings in >=3.8
* Reproduce mismatch between pre-3.8 and post-3.8 behavior on __index__ throwing TypeError
* Fix tests on 3.6 <= Python < 3.8
* No, I don't have an uninitialized variable
* Fix use of __index__ on Python 2
* Make types in test_int_convert more ~boring~ descriptive
* Force the builtin module key to be the correct type.
Previously it was always going to be a std::string which converted into
unicode. Python 2 appears to want module keys to be normal str types, so
this was breaking code that expected plain string types in the
builtins.keys() data structure
* Add a simple unit test to ensure all built-in keys are str
* Update the unit test so it will also run on pypy
* Run pre-commit.

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

3/ adding roundtrip variants to exercise the by reference, by pointer

* 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.

* PyDECREF -> Py_DECREF
* copy/move constructors
* Resolve codereview comments
* more review comment fixes

* 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<>.

I like this version better as it moves the assertion that matters
back into python.
This line had two bugs:
1. It declares `py::detail::class_` as `friend`.
2. After fixing that, we would have to change it to
`template <typename, typename...>`
The first one was introduced ~5 years ago, when a large refactoring was
made, probably as an intermediate step during refactoring.
The second was made when `generic_type` was made to be agnostic with
respect to the order of `py::class_` template parameters.
We're removing the declaration altogether, because it was never relied
on. This is what makes me think that it was an intermediate step in
refactoring that shouldn't have ended up in commit history.

* Initializing PyModuleDef object with PyModuleDef_HEAD_INIT.
Python 3.8 documentation: m_base - Always initialize this member to PyModuleDef_HEAD_INIT.
Long-standing (since first github commit in 2015), inconsequential bug.
Also removing inconsequential Py_INCREF(def): PyModule_Create() resets the reference count to 1.
* git rebase master
* moving static PyModuleDef declaration to global scope, as requested by @wjakob
* renaming the two new macros, to start with PYBIND11_DETAIL_MODULE
This changes enum reprs to look like `<Enum.name: value>` similarly to
the Python enum module.
This keeps the str of enums as `Enum.name`, like the Python enum module.
Support C++20. For backwards compatibility, we provide an alias for the old name.
This change is necessary to easily avoid errors when a compiler thinks
`module` is used as a keyword.
