Currently all this does is add -ignore:4221 to Abseil msvc builds, but the structure is all in place to add more link options when necessary Fix #277 Note: This CL changes tact for us in that it puts the default options in the helper function as opposed to the invocations of absl_cc_blah. The original intent of keeping these out of the helper functions was to make generating the CMakeLists.txt files have a smaller diff, but looking now that is a problem for the future, and small compared to making maintenance and use of our CMake buildsystem easier PiperOrigin-RevId: 240409463 -- 4aa120e9dcf76d29e9ca0008d0f6d4d9fa8abe8c by Matt Kulukundis <kfm@google.com>: Reduce flake rate for non-determistic test to < 1/10,000 PiperOrigin-RevId: 240370938 -- bc30e219531827bfbf90915b2067c7fb8160bb6d by Derek Mauro <dmauro@google.com>: Add Bazel caching on Kokoro for new linux targets.

These are attempted to be limited to in-project installation. This serves two purposes -- first it's morally the same as using Abseil in-source, except you don't have to rebuild us every time. Second, the presence of an install rule makes life massively simpler for package manager maintainers. Currently this doesn't install absl tests or testonly libraries.

Previously there were two different ways to probe for std::hash. One in hash.h and another in type_traits.h, and they were both implemented differently, and neither correctly worked around bad STL implementations. This patch unifies the implementations into a single IsHashable trait. It also: * Correctly checks for old libc++ versions where this won't work. * Avoids undefined behavior which resulted from calling std::is_constructible incomplete types. * Unifies the feature test macro used in the headers and the tests. Additionally it also slightly changes the behavior of when absl::variant is hashable. Previously we disable hashing when std::hash<T>()(key) was formed but when std::hash<T> couldn't be destructed. This seems wrong. If a user provides a evil specialization of std::hash, then it's OK for variant's hash to blow up.

It can produce too high values (up to 256ms), which can negatively affect tail latency. The value was chosen long time ago and now it's a good idea to reconsider it. 2. It does not have low bound, so on any iteration it can produce a very small value that will lead to unnecessary cpu consumption. 3. It does not increase low bound with the number of iterations. So if the SpinLock is actually somehow locked for a very prolonged time, a waiter can still wake periodically. Rework the logic to solve these problems. Add lower bound of 128us, no code should rely on absence of episodic delays in this range as they can occur everywhere. Lower upper bound to 4ms. A thread sleeping for 4ms does not consume significant cpu time (see below). Grow lower bound with the number of iterations. This is cpu consumption of a process doing usleep(x) in a loop (sampled with ps): 64us -> 4.0% 128us -> 2.7% 256us -> 3.5% 512us -> 2.8% 1024us -> 1.6% 2048us -> 0.6% 4096us -> 0.3% 8192us -> 0.0% Few millisecond sleeps do not consume significant time.

This adds a new constexpr constructor to absl::Mutex, invoked with the absl::kConstInit tag value, which is intended to be used to construct Mutex instances with static storage duration. What's tricky about is absl::Mutex (like std::mutex) is not a trivially destructible class, so by the letter of the law, accessing a global Mutex instance after it is destroyed results in undefined behavior. Despite this, we take care in the destructor to not invalidate the memory layout of the Mutex. Using a kConstInit-constructed global Mutex after it is destroyed happens to work on the toolchains we use. Google relies heavily on this behavior internally. Code sanitizers that detect undefined behavior are able to notice use-after-free of globals, and might complain about this pattern.

On ancient versions of msvc and with some compatibility flags on wchar_t is a typedef for unsigned short, whereas on standards-conforming versions wchar_t is a typedef for __wchar_t. The first situation causes int128 to not compile as you can't define both `operator wchar_t()` and `operator unsigned short()` because they are the same type. This CL introduces a wrapper #define in order to abstract over the different typedefs for wchar_t. We do a define instead of a typedef so that we can #undef at the end and not leak the symbol, since we need it in a header. https://docs.microsoft.com/en-us/previous-versions/dh8che7s(v=vs.140) has more detail about the underlying problem.

We may instead want to include() AbseilConfigureCopts.cmake directly into each CMakeLists.txt file for consistency, but I'm not sure what the deal is with cmake and include guards, or if they are even needed.

It can produce too high values (up to 256ms), which can negatively affect tail latency. The value was chosen long time ago and now it's a good idea to reconsider it. 2. It does not have low bound, so on any iteration it can produce a very small value that will lead to unnecessary cpu consumption. 3. It does not increase low bound with the number of iterations. So if the SpinLock is actually somehow locked for a very prolonged time, a waiter can still wake periodically. Rework the logic to solve these problems. Add lower bound of 128us, no code should rely on absence of episodic delays in this range as they can occur everywhere. Lower upper bound to 4ms. A thread sleeping for 4ms does not consume significant cpu time (see below). Grow lower bound with the number of iterations. This is cpu consumption of a process doing usleep(x) in a loop (sampled with ps): 64us -> 4.0% 128us -> 2.7% 256us -> 3.5% 512us -> 2.8% 1024us -> 1.6% 2048us -> 0.6% 4096us -> 0.3% 8192us -> 0.0% Few millisecond sleeps do not consume significant time.

Current calculations in EncodeWaitCycles can result in 0 in kWaitTimeMask and lead to missed wakeups. This is mostly theoretical today, because the futex call needs to finish within 128 cycles (futex can return immediately without waiting, but 128 cycles still look too low for this). But this can well fire in future if we bump granularity and/or threshold for recording contention. Use kSpinLockSleeper instead of 0. PiperOrigin-RevId: 220463123 -- def9b7e3d45c99d68cc52a4429256116d7f421f2 by Abseil Team <absl-team@google.com>: absl: optimize SpinLock::SlowLock Currently we record contention even after the first initial spin. This leads to several performance issues: 1. If we succeed in acquiring the lock after the initial spin, overall wait time can be within tens/hundreds of nanoseconds. Recording such low wait time looks completely unnecessary and excessive. From some point of view this is not even a wait, because we did not sleep. And, for example, Mutex does not record contention in this case. In majority of cases the lock should be acquired exactly during the initial spin, yet we still go through full overhead of submitting contention. 2. Whenever a thread submits contention it also calls FUTEX_WAKE (there is no way to understand if it's necessary or not when wait value is stored in the lock). So if there are just 2 threads and a brief contention, the second thread will still call FUTEX_WAKE which is completely unnecessary overhead. Don't record contention after the initial spin wait. FWIW this also removes 2 CycleClock::Now calls and EncodeWaitCycles from the common hot path.

-- ba4dd47492748bd630462eb68b7959037fc6a11a by Abseil Team <absl-team@google.com>: Work around nvcc 9.0 compiler bug for open-source Tensorflow build. With the current implementation, when I (unintentionally and transitively) include absl/types/optional.h in a CUDA compilation unit, I get the following nvcc error message: INFO: From Compiling tensorflow/core/kernels/crop_and_resize_op_gpu.cu.cc: external/com_google_absl/absl/types/optional.h: In member function 'void absl::optional_internal::optional_data_dtor_base<T, <anonymous> >::destruct()': external/com_google_absl/absl/types/optional.h:185:50: error: '__T0' was not declared in this scope data_.~T(); I've also seen similar compilation failures online, for flat_hash_map: https://devtalk.nvidia.com/default/topic/1042599/nvcc-preprocessor-bug-causes-compilation-failure/ The bug is always around unnamed template parameters. Therefore, the workaround is to make them named.
