* Bazel: Support layering_check and parse_headersGravatar Derek Mauro2023-10-10
| | | | | | | | | | | | | The layering_check feature ensures that rules that include a header explicitly depend on a rule that exports that header. Compiler support is required, and currently only Clang 16+ supports diagnoses layering_check failures. The parse_headers feature ensures headers are self-contained by compiling them with -fsyntax-only on supported compilers.

* Refactor swisstable copy/move assignment to fix issues with allocator ↵Gravatar Evan Brown2023-10-03
| | | | | | | | | | | | | | | | | propagation and improve performance. Correctness: - We use swap to implement copy assignment and move assignment, which means that allocator propagation in copy/move assignment depends on `propagate_on_container_swap` in addition to `propagate_on_container_copy_assignment`/`propagate_on_container_move_assignment`. - In swap, if `propagate_on_container_swap` is `false` and `get_allocator() != other.get_allocator()`, the behavior is undefined (https://en.cppreference.com/w/cpp/container/unordered_set/swap) - we should assert that this UB case isn't happening. For this reason, we also delete the NoPropagateOn_Swap test case in raw_hash_set_allocator_test. Performance: - Don't rely on swap so we don't have to do unnecessary copying into the moved-from sets. - Don't use temp sets in move assignment. - Default the move constructor of CommonFields. - Avoid using exchange in raw_hash_set move constructor. - In `raw_hash_set(raw_hash_set&& that, const allocator_type& a)` with unequal allocators and in move assignment with non-propagating unequal allocators, move set keys instead of copying them.

* absl: optimize Condition checks in Mutex codeGravatar Dmitry Vyukov2023-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Remove special handling of Condition::kTrue. Condition::kTrue is used very rarely (frequently its uses even indicate confusion and bugs). But we pay few additional branches for kTrue on all Condition operations. Remove that special handling and simplify logic. 2. And remove known_false condition in Mutex code. Checking known_false condition only causes slow down because: 1. We already built skip list with equivalent conditions (and keep improving it on every Skip call). And when we built the skip list, we used more capable GuaranteedEqual function (it does not just check for equality of pointers, but for also for equality of function/arg). 2. Condition pointer are rarely equal even for equivalent conditions becuase temp Condition objects are usually created on the stack. We could call GuaranteedEqual(cond, known_false) instead of cond == known_false, but that slows down things even more (see point 1). So remove the known_false optimization.
