PiperOrigin-RevId: 416370158 -- 6bc7b1348fd27fe53f100c9eabd47f4f2cb9c19c by Abseil Team <absl-team@google.com>: Support scoped enum in absl::Substitute. PiperOrigin-RevId: 416345422 -- 6399f4f6ae05ebcd67664ebd844902f699ab8ec7 by Abseil Team <absl-team@google.com>: Correct the computation of contention cycles Currently, we record contention cycles from the first time a thread started waiting on a mutex. Consider a situation in which two threads, T1 and T2, run a loop at the top of which they acquire a common mutex and release it at the end of the loop body. Further assume that T2 is never able to acquire the mutex as T1 repeatedly acquires and then releases the mutex. In this case, we would expect that the reported contention cycles would be increase linearly over time. But currently we observe a quadratic behavior in the reported waiting time as mentioned in b/14684244#comment10. To fix the issue, this CL records the contention cycles experienced by all the threads woken up when the mutex is released. Further, contention_start_cycles is set to the current time since the contention cycles for the time already passed has been taken into account. With this CL, we get a linear increase in the waiting time, the expected behavior.

PiperOrigin-RevId: 387446657 -- 2ca15c6361bb758be7fb88cae82bf8489b4d3364 by Abseil Team <absl-team@google.com>: Change BadStatusOrAccess::what() to contain status_.ToString() This ensures that on uncaught exception propagation that would cause program termination, the message contains information on the error which caused the failure. Lazy initialization of what_ is a value judgement: if most callers are expected to call status() not what(), lazy initialization is correct. If most callers are expected to call what(), it should be initialized on construction to avoid atomic operation overhead.

It’s thus potentially faster, since it doesn’t have to save and restore FPU state. It also is more reflective of developer intent – most developers expect all FPU operations to use the current rounding mode, and having exponential_biased follow that rule seems ideal.

Before this change, we had two classes named HashState: absl::HashState, the public API used for type erasure, and absl::hash_internal::HashState, the internal concrete implementation ordinarily used. The internal class used to be named `CityHashState`, but we renamed it to `HashState` it when we changed underlying hash implementation to wyhash. This inadvertent naming conflict made the code much harder to read, and this change intends to undo that.

PiperOrigin-RevId: 373461406 -- 86b5fd8db50bbc8bd0aa9258523527381fe0445d by Abseil Team <absl-team@google.com>: Improve speed of BlockingCounter by making its most common path lock free. With the new implementation, the fast path of BlockingCounter::DecrementCount() is only a fetch_sub operation. This is most times much more efficient than the previous implementation (full mutex lock/unlock). As a matter of fact, in most actual usecases in practice, the waiter thread is already waiting on the Wait() call when DecrementCount() is called, which makes Mutex::Unlock() take the slow path as there's a waiter thread that it might need to wake up.

Further, bring the implementation on par with libiberty's demangler grammar.

The suffix was designed to work with existing demanglers which do recognize a "_" along with the alphanumeric string. This change enhances the demangler to allow "_" with the alphanumeric string. Please refer to libiberty's cp-demangle.c where function d_clone_suffix implements the demangling of clone suffixes : 1. '_' is accepted as a valid character with the alphanumeric sequence. 2. The alphanumberic sequence is optional. 3. The digit sequence is optional.

The main purpose is to make upcoming ring buffer changes easier to isolate from existing cord.cc code. Notice that this removes the nullptr check from Unref() and now requires it to be non null (which held true most times). We may need to rethink if the 'unref unlikely one' is the common case: are cordreps most likely shared? This may be something between 'root' and non root nodes, i.e., is it more likely for leaf / flat nodes in large cords to be shared than top level cordreps being shared? Vice versa? Benchmarks say that we mostly shouldn't care, the caveat being that atomic ops seem more expensive on upcoming archs (arcadia) so we should error on the side of an extra IsOne() branch saving us single owned atomic ops.

Starting in C++17, when invoke'ing a pointer-to-member, if the object representing the class is a reference_wrapper, that wrapper is unpacked. Because we implement a number of functional APIs that closely match C++ standard proposals, it is better if we follow the standard's notion of what "invoking" means. This also makes `absl::base_internal::Invoke()` match `std::invoke()` in C++17. I intend to make this an alias in a follow-up CL.

* Use base_internal::AtomicHook instead of std::atomic (#661)Gravatar Pavel Samolysov2020-04-14
| | | | | | | | | | | | | | | | | | | * Use base_internal::AtomicHook instead of std::atomic std::atomic has a broken implementation on the Windows platform and it is not conform to the ABSL_CONST_INIT macro when clang-cl is used as a compiler: the macro is expanded to the [[clang::require_constant_initialization]] attribute and the attribute cannot be applied to the broken std::atomic. Therefore, std::atomic has been replaced with absl::base_internal::AtomicHook to fix the compilation error (thank Derek Mauro for the suggestion).
