[smart_holder] `type_caster` ODR guard (#4022) * Insert type_caster_odr_guard<> (an empty struct to start with). * Add odr_guard_registry() used in type_caster_odr_guard() default constructor. * Add minimal_real_caster (from PR #3862) to test_async, test_buffers * VERY MESSY SNAPSHOT of WIP, this was the starting point for cl/454658864, which has more changes on top. * Restore original test_async, test_buffers from current smart_holder HEAD * Copy from cl/454991845 snapshot Jun 14, 5:08 PM * Cleanup of tests. Systematically insert `if (make_caster<T>::translation_unit_local) {` * Small simplification of odr_guard_impl() * WIP * Add PYBIND11_SOURCE_FILE_LINE macro. * Replace PYBIND11_TYPE_CASTER_UNIQUE_IDENTIFIER with PYBIND11_TYPE_CASTER_SOURCE_FILE_LINE, baked into PYBIND11_TYPE_CASTER macro. * Add more PYBIND11_DETAIL_TYPE_CASTER_ACCESS_TRANSLATION_UNIT_LOCAL; resolves "unused" warning when compiling test_custom_type_casters.cpp * load_type fixes & follow-on cleanup * Strip ./ from source_file_line * Add new tests to CMakeLists.txt, disable PYBIND11_WERROR * Replace C++17 syntax. Compiles with Debian clang 13 C++11 mode, but fails to link. Trying GitHub Actions anyway to see if there are any platforms that support https://en.cppreference.com/w/cpp/language/tu_local before C++20. Note that Debian clang 13 C++17 works locally. * Show C++ version along with ODR VIOLATION DETECTED message. * Add source_file_line_basename() * Introduce PYBIND11_TYPE_CASTER_ODR_GUARD_ON (but not set automatically). * Minor cleanup. * Set PYBIND11_TYPE_CASTER_ODR_GUARD_ON automatically. * Resolve clang-tidy error. * Compatibility with old compilers. * Fix off-by-one in source_file_line_basename() * Report PYBIND11_INTERNALS_ID & C++ Version from pytest_configure() * Restore use of PYBIND11_WERROR * Move cpp_version_in_use() from cast.h to pybind11_tests.cpp * define PYBIND11_DETAIL_ODR_GUARD_IMPL_THROW_DISABLED true in test_odr_guard_1,2.cpp * IWYU cleanup of detail/type_caster_odr_guard.h * Replace `throw err;` to resolve clang-tidy error. * Add new header filename to CMakeLists.txt, test_files.py * Experiment: Try any C++17 compiler. * Fix ifdef for pragma GCC diagnostic. * type_caster_odr_guard_impl() cleanup * Move type_caster_odr_guard to type_caster_odr_guard.h * Rename test_odr_guard* to test_type_caster_odr_guard* * Remove comments that are (now) more distracting than helpful. * Mark tu_local_no_data_always_false operator bool as explicit (clang-tidy). See also: https://stackoverflow.com/questions/39995573/when-can-i-use-explicit-operator-bool-without-a-cast * New PYBIND11_TYPE_CASTER_ODR_GUARD_STRICT option (current on by default). * Add test_type_caster_odr_registry_values(), test_type_caster_odr_violation_detected_counter() * Report UNEXPECTED: test_type_caster_odr_guard_2.cpp prevailed (but do not fail). * Apply clang-tidy suggestion. * Attempt to handle valgrind behavior. * Another attempt to handle valgrind behavior. * Yet another attempt to handle valgrind behavior. * Trying a new direction: show compiler info & std for UNEXPECTED: type_caster_odr_violation_detected_count() == 0 * compiler_info MSVC fix. num_violations == 0 condition. * assert pybind11_tests.compiler_info is not None * Introduce `make_caster_intrinsic<T>`, to be able to undo the 2 changes from `load_type` to `load_type<T>`. This is to avoid breaking 2 `pybind11::detail::load_type()` calls found in the wild (Google global testing). One of the breakages in the wild was: https://github.com/google/tensorstore/blob/0f0f6007670a3588093acd9df77cce423e0de805/python/tensorstore/subscript_method.h#L61 * Add test for stl.h / stl_bind.h mix.
