…erywhere **except when libc++ is in use** (#4319) * Try using `std::hash<std::type_index>`, `std::equal_to<std::type_index>` everywhere. From PR #4316 we know that types in the unnamed namespace in different translation units do not compare equal, as desired. But do types in named namespaces compare equal, as desired? * Revert "Try using `std::hash<std::type_index>`, `std::equal_to<std::type_index>` everywhere." This reverts commit a06949a. * Use "our own name-based hash and equality functions" for `std::type_index` only under macOS, based on results shown under #4316 (comment) * Patch in PR #4313: Minimal reproducer for clash when binding types defined in the unnamed namespace. * test_unnamed_namespace_b xfail for clang * `PYBIND11_INTERNALS_VERSION 5` * Add a note to docs/classes.rst * For compatibility with Google-internal testing, test_unnamed_namespace_a & test_unnamed_namespace_b need to work when imported in any order. * Trying "__GLIBCXX__ or Windows", based on observations from Google-internal testing. * Try _LIBCPP_VERSION * Account for libc++ behavior in tests and documentation. * Adjust expectations for Windows Clang (and make code less redundant). * Add WindowsClang to ci.yml Added block transferred from PR #4321 * Add clang-latest to name that appears in the GitHub Actions web view. * Tweak the note in classes.rst again. * Add `pip install --upgrade pip`, Show env, cosmetic changes Already tested under PR #4321 * Add macos_brew_install_llvm to ci.yml Added block transferred from PR #4324 * `test_cross_module_exception_translator` xfail 'Homebrew Clang' * Revert back to base version of .github/workflows/ci.yml (the ci.yml changes were merged under #4323 and #4326) * Fixes for ruff * Make updated condition in internals.h dependent on ABI version. * Remove PYBIND11_TEST_OVERRIDE when testing with PYBIND11_INTERNALS_VERSION=10000000 * Selectively exercise cmake `-DPYBIND11_TEST_OVERRIDE`: ubuntu, macos, windows Extra work added to quick jobs, based on timings below, to not increase the GHA start-to-last-job-finished time. ``` Duration ^ Number of pytest runs ^ ^ Job identifier ^ ^ ^ 0:03:48.024227 1 1___3___Clang_3.6___C++11___x64.txt
