Removing MSVC C4127 from pragma block at the top of pybind11.h (#3152)
* Removing pragma for 4127 (to see what is still broken with the latest code).

* Using new constexpr_bool() to suppress warning C4127.

* One missed case, Python 2 only.

* PYBIND11_SILENCE_MSVC_C4127 (more similar to the approach for C4100).

Moving pragma for MSVC warning C4505 from pybind11.h to existing list in detail/common.h (#3160)
* Moving pragma for C4505 from pybind11.h to existing list in detail/common.h.

* Removing 4 existing suppressions to 1. see what is still needed and 2. capture the MSVC messages.

* It turns out none of the 4 pragmas are needed anymore.

fix: Mingw64 corrected and add a CI job to test it (#3132)
* mingw64 platform string is like mingw_xxx not "mingw"

See https://github.com/msys2/MINGW-packages/blob/master/mingw-w64-python/0099-Change-the-get_platform-method-in-sysconfig-and-dist.patch

* Mingw: Do not dllexport exceptions

This is a fix for errors like:

D:/a/pybind11/pybind11/include/pybind11/detail/common.h:735:23: error: 'dllexport' implies default visibility, but 'class pybind11::builtin_exception' has already been declared with a different visibility
  735 | class PYBIND11_EXPORT builtin_exception : public std::runtime_error {
      |                       ^~~~~~~~~~~~~~~~~

* GHA: Test Mingw64 build

* fix: avoid thin binaries on mingw

* fix: drop lto on MinGW

* Mingw64: disable PYBIND11_DEPRECATED

It trigger many warnings for unknown reasons

Limiting pragma for ignoring GCC 7 -Wnoexcept-type to the scope of pybind11.h. (#3161)
* Moving pragma for ignoring -Wnoexcept-type to the one location where it is needed.

* Trying a second location.

* The previous commit worked (GitHub Actions green), but see the added comment about the dicy nature of -Wnoexcept-type ("if and only if").

* Applying reviewer suggestion.

Feature/local exception translator (#2650)
* 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

* Add back a missing space

* Clean-up some issues in the docs

* Remove the code duplication when translating exceptions

Separated out the exception processing into a standalone function in the
details namespace.

Clean-up some comments as per PR notes as well

* Remove the code duplication in register_exception

* Cleanup some formatting things caught by clang-format

* Remove the templates from exception translators

But I added a using declaration to alias the type.

* Remove the extra local from local_internals variable names

* Add an extra explanatory comment to local_internals

* Fix a typo in the code

Splitting out pybind11/stl/filesystem.h. (#3077)
* 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.

Ralf W. Grosse-Kunstleve 48eb78ae77 Simpler and safe implementation based on new requirement: C++ (outside of the Python object) needs to hold a shared_ptr before shared_from_this is called. This is more similar to the existing implementation on current smart_holder HEAD, but still uses a weak_ptr to always return the same shared_ptr as long as C++ does not let it expire. 2021-06-30 07:04:31 -07:00

Ralf W. Grosse-Kunstleve 20ef96c87d Disabling debugging call of `weak_from_this` for C++ < 17. 2021-06-30 07:04:31 -07:00
Ralf W. Grosse-Kunstleve bf8d6a2900 First fully successful attempt to make `shared_from_this` and trampolines play nicely.
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.

smart_holder fixups (#3012)
* 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"

Fix compilation with gcc < 5 (#2956)
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.

* Demonstration of Undefined Behavior in handling of shared_ptr holder.

Based on https://godbolt.org/z/4fdjaW by jorgbrown@ (thanks Jorg!).

* Additional demonstration of Undefined Behavior in handling of shared_ptr holder.

* fixing up-down mixup in comment

* Demonstration of Undefined Behavior in handling of polymorphic pointers.

(This demo does NOT involve smart pointers at all, unlike the otherwise similar test_smart_ptr_private_first_base.)

* minor test_private_first_base.cpp simplification (after discovering that this can be wrapped with Boost.Python, using boost::noncopyable)

* pybind11 equivalent of Boost.Python test similar to reproducer under #1333

* Snapshot of WIP, TODO: shared_ptr deleter with on/off switch

* Adding vptr_deleter.

* Adding from/as unique_ptr<T> and unique_ptr<T, D>.

* Adding shared_ptr<mpty>, shared_ptr<mpty const> casters.

* Adding unique_ptr<mpty>, unique_ptr<mpty const> casters.

* Pure copy of `class class_` implementation in pybind11.h (master commit 98f1bbb800).

* Pure `clang-format --style=file -i` change, with two `clang-format off` directives.

* Fixing oversight (discovered by flake8).

* flake8 cleanup

* Systematically setting mtxt for all rtrn_mpty_* functions (preparation, the values are not actually used yet).

* 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.

* Copying type_caster_generic::cast into type_caster<mpty> as-is (preparation for handling smart pointers).

* Pure clang-format change (applied to original type_caster_generic::cast).

* Adding comment re potential use_count data race.

* static handle cast implementations for rtrn_uqmp, rtrn_uqcp.

* Bug fix: vptr_deleter_armed_flag_ptr has to live on the heap.

See new bullet point in comment section near the top.

The variable was also renamed to reflect its function more accurately.

* Fixing bugs discovered by ASAN. The code is now ASAN, MSAN, UBSAN clean.

* 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.

First results: https://docs.google.com/spreadsheets/d/1InapCYws2Gt-stmFf_Bwl33eOMo3aLE_gc9adveY7RU/edit#gid=0

* Breaking out number_bucket.h, adding hook for also collecting performance data for PyCLIF.

* Accounting for ubench in MANIFEST.in (simply prune, for now).

* Renaming is_smart_holder_type_caster_base_tag -> smart_holder_type_caster_base_tag for simplicity.

* Adding copyright notices and minor colateral cleanup.

* iwyu cleanup (comprehensive only for cast.h and smart_holder*.h files).

* Fixing `git rebase master` accident.

* Moving large `pragma warning` block from pybind11.h to detail/common.h.

* Fixing another `git rebase master` accident.

Force the builtin module key to be the correct type. (#2814)
* 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.

CI: Intel ICC with C++17

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
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<>.

* apply presubmit formatting

* Revert inclusion of test_freezable_type_caster

There's some concern that this test is a bit unwieldly because of the use
of the raw <Python.h> functions. Removing for now.

* Add a test that validates const references propagation.

This test verifies that cast_op may be used to correctly detect
const reference types when used with std::reference_wrapper.

* mend

* Review comments based changes.

1. std::add_lvalue_reference<type> -> type&
2. Simplify the test a little more; we're never returning the ConstRefCaster
type so the class_ definition can be removed.

* formatted files again.

* Move const_ref_caster test to builtin_casters

* Review comments: use cast_op and adjust some comments.

* Simplify ConstRefCasted test

I like this version better as it moves the assertion that matters
back into python.

Remove friend declaration of py::class_ in py::detail::generic_type (#2613)
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.

&nbsp;

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.

Fix buffer_info for ctypes buffers (pybind#2502) (#2503)
* tests: New test for ctypes buffers (pybind#2502)

* fix: fix buffer_info segfault on views with no stride (pybind11#2502)

* Explicit conversions in buffer_info to make clang happy (pybind#2502)

* Another explicit cast in buffer_info constructor for clang (pybind#2502)

* Simpler implementation of buffer_info constructor from Py_buffer.

* Move test_ctypes_buffer into test_buffers

* Comment on why view->strides may be NULL (and fix some whitespace)

* Use c_strides() instead of zero when view->strides is NULL.

c_strides and f_strides are moved from numpy.h (py::array)
to buffer_info.h (py::detail) so they can be used from the
buffer_info Py_buffer constructor.

* Increase ctypes buffer test coverage in test_buffers.

* Split ctypes tests and skip one which is broken in PyPy2.

Ralf W. Grosse-Kunstleve 3c061f2168 Fixing `pybind11::bytes()` ambiguous conversion issue.
Adding missing `bytes` type to `test_constructors()`, to exercise the code change.

The changes in the PR were cherry-picked from PR #2409 (with a very minor
modification in test_pytypes.py related to flake8). Via PR #2409, these
changes were extensively tested in the Google environment, as summarized here:
https://docs.google.com/document/d/1TPL-J__mph_yHa1quDvsO12E_F5OZnvBaZlW9IIrz8M/
The changes in this PR did not cause an issues at all.

Note that `test_constructors()` before this PR passes for Python 2 only
because `pybind11::str` can hold `PyUnicodeObject` or `PyBytesObject`. As a
side-effect of this PR, `test_constructors()` no longer relies on this
permissive `pybind11::str` behavior. However, the permissive behavior is still
exercised/exposed via the existing `test_pybind11_str_raw_str()`.

The test code change is designed to enable easy removal later, when Python 2
support is dropped.

For completeness: confusingly, the non-test code changes travelled through PR

Example `ambiguous conversion` error fixed by this PR:
```
pybind11/tests/test_pytypes.cpp:214:23: error: ambiguous conversion for functional-style cast from 'pybind11::detail::item_accessor' (aka 'accessor<accessor_policies::generic_item>') to 'py::bytes'

Avoid attr("__repr__") in initialize_generic (#2317)
If the default argument value is a class, and not an instance of a

This change defines a new, portable macro PYBIND11_MAYBE_UNUSED to
mark declarations as unused, and annotates the PYBIND11_MODULE entry
point with this attribute.

The purpose of this annotation is to facilitate dead code detection,
which might otherwise consider the module entry point function dead,
since it isn't otherwise used. (It is only used via FFI.)

This adds support for a `py::args_kw_only()` annotation that can be

arguments are keyword-only.  This allows you to write:

    m.def("f", [](int a, int b) { /* ... */ },
          py::arg("a"), py::args_kw_only(), py::arg("b"));

and have it work like Python 3's:

    def f(a, *, b):
        # ...

with respect to how `a` and `b` arguments are accepted (that is, `a` can
be positional or by keyword; `b` can only be specified by keyword).

Currently user specializations of the form

will fail if itype is also polymorphic, because the existing specialization will also
be enabled, which leads to 2 equally viable candidates. With this change, user provided
specializations have higher priority than the built in specialization for polymorphic types.

Wenzel Jakob bf2b031449 Handle cases where binding code immediately throws py::error_already_set
When binding code immediately throws an exception of type
py::error_already_set (e.g. via py::module::import that fails), the
catch block sets an import error as expected. Unfortunately, following
this, the deconstructor of py::error_already_set decides to call
py::detail::get_internals() and set up various internal data structures
of pybind11, which fails given that the error flag is active. The call
stack of this looks as follows:

Py_init_mymodule() -> __cxa_decrement_exception_refcount ->
error_already_set::~error_already_set() ->
gil_scoped_acquire::gil_scoped_acquire() -> detail::get_internals() ->
... -> pybind11::detail::simple_collector() -> uh oh..

The solution is simple: we call detail::get_internals() once before
running any binding code to make sure that the internal data structures
are ready.

Use C++17 fold expressions when casting tuples and argument lists (#2043)
This commit introduces the use of C++17-style fold expressions when
casting tuples & the argument lists of functions.

This change can improve performance of the resulting bindings: because
fold expressions have short-circuiting semantics, pybind11 e.g. won't
try to cast the second argument of a function if the first one failed.
This is particularly effective when working with functions that have
many overloads with long argument lists.

Sebastian Gsänger a83d69e78f test pair-copyability on C++17 upwards (#1886)
* test pair-copyability on C++17 upwards

The stdlib falsely detects containers like M=std::map<T, U>
as copyable, even when one of T and U is not copyable.
Therefore we cannot rely on the stdlib dismissing std::pair<T, M>
by itself, even on C++17.

* fix is_copy_assignable

bind_map used std::is_copy_assignable which suffers from the same problems
as std::is_copy_constructible, therefore the same fix has been applied.

* created tests for copyability
