* 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.

* Check default holder
-Recognize "std::unique_ptr<T, D>" as a default holder even if "D" doesn't match between base and derived holders
* Add test for unique_ptr<T, D> change
This udpates all the remaining tests to the new test suite code and
comment styles started in #898. For the most part, the test coverage
here is unchanged, with a few minor exceptions as noted below.
- test_constants_and_functions: this adds more overload tests with
overloads with different number of arguments for more comprehensive
overload_cast testing. The test style conversion broke the overload
tests under MSVC 2015, prompting the additional tests while looking
for a workaround.
- test_eigen: this dropped the unused functions `get_cm_corners` and
`get_cm_corners_const`--these same tests were duplicates of the same
things provided (and used) via ReturnTester methods.
- test_opaque_types: this test had a hidden dependence on ExampleMandA
which is now fixed by using the global UserType which suffices for the
relevant test.
- test_methods_and_attributes: this required some additions to UserType
to make it usable as a replacement for the test's previous SimpleType:
UserType gained a value mutator, and the `value` property is not
mutable (it was previously readonly). Some overload tests were also
added to better test overload_cast (as described above).
- test_numpy_array: removed the untemplated mutate_data/mutate_data_t:
the templated versions with an empty parameter pack expand to the same
thing.
- test_stl: this was already mostly in the new style; this just tweaks
things a bit, localizing a class, and adding some missing
`// test_whatever` comments.
- test_virtual_functions: like `test_stl`, this was mostly in the new
test style already, but needed some `// test_whatever` comments.
This commit also moves the inherited virtual example code to the end
of the file, after the main set of tests (since it is less important
than the other tests, and rather length); it also got renamed to
`test_inherited_virtuals` (from `test_inheriting_repeat`) because it
tests both inherited virtual approaches, not just the repeat approach.
This commit allows multiple inheritance of pybind11 classes from
Python, e.g.
class MyType(Base1, Base2):
def __init__(self):
Base1.__init__(self)
Base2.__init__(self)
where Base1 and Base2 are pybind11-exported classes.
This requires collapsing the various builtin base objects
(pybind11_object_56, ...) introduced in 2.1 into a single
pybind11_object of a fixed size; this fixed size object allocates enough
space to contain either a simple object (one base class & small* holder
instance), or a pointer to a new allocation that can contain an
arbitrary number of base classes and holders, with holder size
unrestricted.
* "small" here means having a sizeof() of at most 2 pointers, which is
enough to fit unique_ptr (sizeof is 1 ptr) and shared_ptr (sizeof is 2
ptrs).
To minimize the performance impact, this repurposes
`internals::registered_types_py` to store a vector of pybind-registered
base types. For direct-use pybind types (e.g. the `PyA` for a C++ `A`)
this is simply storing the same thing as before, but now in a vector;
for Python-side inherited types, the map lets us avoid having to do a
base class traversal as long as we've seen the class before. The
change to vector is needed for multiple inheritance: Python types
inheriting from multiple registered bases have one entry per base.
Using a dynamic_cast instead of a static_cast is needed to safely cast
from a base to a derived type. The previous static_pointer_cast isn't
safe, however, when downcasting (and fails to compile when downcasting
with virtual inheritance).
Switching this to always use a dynamic_pointer_cast shouldn't incur any
additional overhead when a static_pointer_cast is safe (i.e. when
upcasting, or self-casting): compilers don't need RTTI checks in those
cases.
Instead of a segfault. Fixes#751.
This covers the case of loading a custom holder from a default-holder
instance. Attempting to load one custom holder from a different custom
holder (i.e. not `std::unique_ptr`) yields undefined behavior, just as
#588 established for inheritance.
* Abstract away some holder functionality (resolve#585)
Custom holder types which don't have `.get()` can select the correct
function to call by specializing `holder_traits`.
* Add support for move-only holders (fix#605)
A flake8 configuration is included in setup.cfg and the checks are
executed automatically on Travis:
* Ensures a consistent PEP8 code style
* Does basic linting to prevent possible bugs
Currently pybind11 only supports std::unique_ptr<T> holders by default
(other holders can, of course, be declared using the macro). PR #368
added a `py::nodelete` that is intended to be used as:
py::class_<Type, std::unique_ptr<Type, py::nodelete>> c("Type");
but this doesn't work out of the box. (You could add an explicit
holder type declaration, but this doesn't appear to have been the
intention of the commit).
This commit fixes it by generalizing the unique_ptr type_caster to take
both the type and deleter as template arguments, so that *any*
unique_ptr instances are now automatically handled by pybind. It also
adds a test to test_smart_ptr, testing both that py::nodelete (now)
works, and that the object is indeed not deleted as intended.
Use simple asserts and pytest's powerful introspection to make testing
simpler. This merges the old .py/.ref file pairs into simple .py files
where the expected values are right next to the code being tested.
This commit does not touch the C++ part of the code and replicates the
Python tests exactly like the old .ref-file-based approach.
