| | | | | | | | | | | | | | | | | | TSan misses synchronization around passing PerThreadSynch between threads since it happens inside of the Mutex code (which me mostly ignore), so we need to ignore all accesses to the object.

* | Add a new API for `extract_and_get_next()` in b-tree that returns both the ↵Gravatar Evan Brown2022-11-15
| | | | | | | | | | | | | | | | extracted node and an iterator to the next element in the container. Motivation: it can be useful, when calling `extract` to maintain an iterator next to the location of the extracted element. `std::set`, et al. allow for this because they have iterator stability. `absl::{flat,node}_hash_{set,map}` allow for this because they are guaranteed not to rehash when elements are removed so they also have iterator stability across calls to `extract()`. But b-tree doesn't support this use case without this API because removing elements can cause rebalancing, which invalidates iterators. We can get the next iterator without this API using `lower_bound(node_handle.value())`, but that requires an extra lookup.

However, value-initialized iterators may be compared and shall compare equal to other value-initialized iterators of the same type." - [reference](https://eel.is/c++draft/forward.iterators#2). - Also optimize IsEndIterator a bit.

Another option would have been to use macros to only initialize std::atomic_flag before C++20, but I decided to use one compilation path instead.

* | Force a conservative allocation for pointers to methods in Condition objects.Gravatar Abseil Team2022-11-07
| | | | | | | | | | | | | | | | | | | | | | In order for Condition to work on Microsoft platforms, it has to store pointers to methods that are larger than we usually expect. MSVC pointers to methods from class hierarchies that employ multiple inheritance or virtual inheritance are strictly larger than pointers to methods in class hierarchies that only employ single inheritance. This change introduces an opaque declaration of a class, which is not fulfilled. This declaration is used to calculate the size of the Condition method pointer allocation. Because the declaration is of unspecified inheritance, the compiler is forced to use a conservatively large allocation, which will thereby accommodate all method pointer sizes. Because the `method_` and `function_` callbacks are only populated in mutually exclusive conditions, they can be allowed to take up the same space in the Condition object. This change combines the `method_` and `function_` fields and renames the new field to `callback_`. The constructor logic is updated to reflect the new field.
