Ralf W. Grosse-Kunstleve	bc3cd8a8a8	Splitting out include/pybind11/detail/pragma_warning_block.h (#2988) ... * Splitting out include/pybind11/detail/pragma_warning_block.h * Always including pragma_warning_block.h before common.h (resolved 8 CI failures).	2021-05-03 22:08:04 -07:00
Ralf W. Grosse-Kunstleve	6c922614ed	Adding reclaim_disowned logic & miscellaneous naming and documentation improvements. (#2943) ... * 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.	2021-04-09 23:08:44 -07:00
Ralf W. Grosse-Kunstleve	0b63dd0eb2	Adding initial README_smart_holder.rst. (#2936) ... * Adding initial README_smart_holder.rst. * Adding README_smart_holder.rst to MANIFEST.in and test_files.py.	2021-04-05 13:47:48 -07:00
Ralf W. Grosse-Kunstleve	5319ca3817	Using dynamic_cast<AliasType> to determine pointee_depends_on_holder_owner. (#2910) ... * 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.	2021-03-19 12:18:39 -07:00
Ralf W. Grosse-Kunstleve	469792032a	Adding virtual_overrider_self_life_support. (#2902) ... * 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.	2021-03-16 06:31:24 -07:00
Ralf W. Grosse-Kunstleve	1bafd5db5f	Adding py::smart_holder (for smart-pointer interoperability). (#2672) ... * Adding test_unique_ptr_member (for desired PyCLIF behavior).

Some polishing. * New tests/core/smart_holder_poc_test.cpp, using Catch2. * Adding in vptr_deleter_guard_flag. * Improved labeling of TEST_CASEs. * Shuffling existing TEST_CASEs into systematic matrix. * Implementing all [S]uccess tests. * Implementing all [E]xception tests. * Testing of exceptions not covered by the from-as matrix. * Adding top-level comment. * Converting from methods to factory functions (no functional change). * Removing obsolete and very incomplete test (replaced by Catch2-based test). * Removing stray file. * Adding type_caster_bare_interface_demo. * 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). * classh.h: renaming of class_ to classh + namespace; forking test_classh_wip from test_type_caster_bare_interface_demo. * Hard-coding smart_holder into classh. * Adding mpty::mtxt string member. * Adding isinstance<mpty> in type_caster::load functions. * Adding rvalue_ref, renaming const_value_ref to lvalue_ref & removing const. * Retrieving smart_holder pointer in type_caster<mpty>::load, and using it cast_op operators. * Factoring out smart_holder_type_caster_load. * Retrieving smart_holder pointer in type_caster<std::shared_ptr<mpty[ const]>>::load, and using it cast_op operators. * Improved error messaging: Cannot disown nullptr (as_unique_ptr). * Retrieving smart_holder pointer in type_caster<std::unique_ptr<mpty[ const]>>::load, and using it cast_op operators. * Pure `clang-format --style=file -i` change. * 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_shmp, rtrn_shcp. * Adding MISSING comments in operator std::unique_ptr<mpty[ const]>. * 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). * Smarter determination of call_repetitions. [skip ci] * Also scaling performance data to PyCLIF. [skip ci] * Adding ubench/python/number_bucket.clif here for general visibility. * Fix after rebase * Merging detail/smart_holder_init_inline_include.h into detail/init.h. * Renaming detail/is_smart_holder_type_caster.h -> detail/smart_holder_sfinae_hooks_only.h. * Renaming is_smart_holder_type_caster -> type_uses_smart_holder_type_caster for clarity. * Renaming type_caster_type_is_smart_holder_type_caster -> wrapped_type_uses_smart_holder_type_caster for clarity. * 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.	2021-02-23 21:50:42 -08:00
