* Change the macro ABSL_IS_TRIVIALLY_RELOCATABLE into a type trait - ↵Gravatar Evan Brown2022-09-20
| | | | | | | | | | | | | | | | | | | | | | absl::is_trivially_relocatable - and move it from optimization.h to type_traits.h. Example of how to change to the new type trait: ``` #include "absl/base/attributes.h" if (ABSL_IS_TRIVIALLY_RELOCATABLE(T)) { DoSomething(); } ``` to ``` #include "absl/meta/type_traits.h" if (absl::is_trivially_relocatable<T>::value) { DoSomething(); } ``` Note that optimization.h is also built in C mode so we can't put a type trait there.

* Make BTrees work with custom allocators that recycle memory.Gravatar Abseil Team2022-09-19
| | | | | | | | | | | | The btree data structure poisons regions of memory it's not using. It leaves these regions poisoned when it frees memory. This means that a custom memory allocator that tries to reuse freed memory will trigger an ASAN use-after-poison error. The fix is to unpoison each memory region right before freeing it.
