# Notes on disabled checks
# ------------------------
# modernize-use-equals-default:
#     auto-fix is broken (doesn't insert =default correctly)
# modernize-concat-nested-namespaces:
#     auto-fix is broken (can delete code)
# modernize-use-trailing-return-type:
#     Purely stylistic, no benefit to rewriting everything
# modernize-return-braced-init-list:
#     Stylistically we prefer to see the return type at the return site.
#     See https://github.com/rapidsai/cudf/pull/16956#pullrequestreview-2341891672
#     for more information.
# modernize-use-bool-literals:
#     Our tests use int flags for validity masks extensively and we prefer that
# modernize-use-constraints:
#     New check that requires a C++20 feature
# modernize-use-ranges:
#     New check that requires a C++20 feature
# modernize-use-designated-initializers:
#     New check that requires a C++20 feature
# clang-analyzer-cplusplus.NewDeleteLeaks:
#     This check has numerous bugs, see
#     https://github.com/llvm/llvm-project/issues?q=is%3Aissue+is%3Aopen+newdeleteleaks
#     We encounter at least
#     https://github.com/llvm/llvm-project/issues/60896
#     https://github.com/llvm/llvm-project/issues/69602
# clang-analyzer-optin.core.EnumCastOutOfRange
#     We use enums as flags in multiple cases and this check makes ORing flags invalid
# clang-analyzer-optin.cplusplus.UninitializedObject'
#     There is an error in nanoarrow that none of the clang-tidy filters (i.e.
#     header-filter and exclude-header-filter are able to properly avoid. This
#     merits further investigation
#
# We need to verify that broken checks are still broken
