* Equivalent of5718e4d080* Resolve clang-tidy errors. * Moving test_PPCCInit() first changes the behavior! * Resolve new Clang dev C++11 errors: ``` The CXX compiler identification is Clang 17.0.0 ``` ``` pytypes.h:1615:23: error: identifier '_s' preceded by whitespace in a literal operator declaration is deprecated [-Werror,-Wdeprecated-literal-operator] ``` ``` cast.h:1380:26: error: identifier '_a' preceded by whitespace in a literal operator declaration is deprecated [-Werror,-Wdeprecated-literal-operator] ``` * Resolve gcc 4.8.5 error: ``` pytypes.h:1615:12: error: missing space between '""' and suffix identifier ``` * Specifically exclude `__clang__` * Snapshot of debugging code (does NOT pass pre-commit checks). * Revert "Snapshot of debugging code (does NOT pass pre-commit checks)." This reverts commit1d4f9ff263. * [ci skip] Order Dependence Demo * Revert "[ci skip] Order Dependence Demo" This reverts commitd37b5409d4. * One way to deal with the order dependency issue. This is not the best way, more like a proof of concept. * Move test_PC() first again. * Add `all_type_info_add_base_most_derived_first()`, use in `all_type_info_populate()` * Revert "One way to deal with the order dependency issue. This is not the best way, more like a proof of concept." This reverts commiteb09c6c1b9. * clang-tidy fixes (automatic) * Add `is_redundant_value_and_holder()` and use to avoid forcing `__init__` overrides when they are not needed. * Streamline implementation and avoid unsafe `reinterpret_cast<instance *>()` introduced with PR #2152 The `reinterpret_cast<instance *>(self)` is unsafe if `__new__` is mocked, which was actually found in the wild: the mock returned `None` for `self`. This was inconsequential because `inst` is currently cast straight back to `PyObject *` to compute `all_type_info()`, which is empty if `self` is not a pybind11 `instance`, and then `inst` is never dereferenced. However, the unsafe detour through `instance *` is easily avoided and the updated implementation is less prone to accidents while debugging or refactoring. * Fix actual undefined behavior exposed by previous changes. It turns out the previous commit message is incorrect, the `inst` pointer is actually dereferenced, in the `value_and_holder` ctor here:f3e0602802/include/pybind11/detail/type_caster_base.h (L262-L263)``` 259 // Main constructor for a found value/holder: 260 value_and_holder(instance *i, const detail::type_info *type, size_t vpos, size_t index) 261 : inst{i}, index{index}, type{type}, 262 vh{inst->simple_layout ? inst->simple_value_holder 263 : &inst->nonsimple.values_and_holders[vpos]} {} ``` * Add test_mock_new() * Experiment: specify indirect bases * Revert "Experiment: specify indirect bases" This reverts commit4f90d85f9f. * Add `all_type_info_check_for_divergence()` and some tests. * Call `all_type_info_check_for_divergence()` also from `type_caster_generic::load_impl<>` * Resolve clang-tidy error: ``` include/pybind11/detail/type_caster_base.h:795:21: error: the 'empty' method should be used to check for emptiness instead of 'size' [readability-container-size-empty,-warnings-as-errors] if (matching_bases.size() != 0) { ^~~~~~~~~~~~~~~~~~~~~~~~~~ !matching_bases.empty() ``` * Revert "Resolve clang-tidy error:" This reverts commitdf27188dc6. * Revert "Call `all_type_info_check_for_divergence()` also from `type_caster_generic::load_impl<>`" This reverts commit5f5fd6a68e. * Revert "Add `all_type_info_check_for_divergence()` and some tests." This reverts commit0a9599f775.
