Abseil Team	eab2078b53	Export of internal Abseil changes. -- 8b7c3bc2fb69608e9b2389b1be0b0de840a4c59d by Derek Mauro <dmauro@google.com>: Set correct flags for clang-cl. https://github.com/abseil/abseil-cpp/pull/278 clang-cl produce binaries with MSVC ABI and wants to be as flag-compatible with pure MSVC as possible, so this leads to all sorts of weird cases. clang-cl alias /Wall as clang's -Weverything which is way too verbose, so it needs /W3 like pure MSVC. clang-cl only understand GCC style warning flags (-W[no]blah) and just silent drop MSVC style warning flags (/wd[num]). clang-cl needs MSVC define flags since it is consuming the same header files as pure MSVC. CMake set CMAKE_CXX_COMPILER_ID as Clang when clang-cl is detected, so need extra if (MSVC) to differentiate it. We are not doing clang-cl specialization in Bazel as currently there is no reliable way to detect clang-cl in Bazel.. Other changes: Add ABSL_ prefix to variable names to avoid name collision in CMake. PiperOrigin-RevId: 239841297 -- add96c3fc067d5c7b6f016d2ba74725a443a185e by CJ Johnson <johnsoncj@google.com>: Eventually Storage will need to refer to the type `absl::InlinedVector<...>*`. This can be done via a forward declaration. However, doing so would move the defaulted allocator template parameter to the forward declaration and thus inside an internal file. Instead of doing that, this change gives Storage access to the template and it's parameters so the complete type can be formed without including it.

PiperOrigin-RevId: 239622024 -- d1cb234dc5706f033ad56f4eb16d94ac5da80d52 by Abseil Team <absl-team@google.com>: Mutex: fix tsan annotations This fixes 2 bugs: 1. We call cond directly in Mutex::AwaitCommon without using EvalConditionAnnotated. As the result we call into user code ignoring synchronization, miss synchronization and report false positives later. Use EvalConditionAnnotated to call cond as we should. 2. We call Mutex invariant ignoring synchronization. Result is the same: we miss synchronization and report false positive races later. Reuse EvalConditionAnnotated to call mutex invariant too.

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. This can be added in a follow-up patch.

Abseil Team	7c7754fb3e	Export of internal Abseil changes. -- 89b5e681db1d4f0b039daebb86c49bda77c8931b by Tom Manshreck <shreck@google.com>: Add clarification that absl::Hash does not produce stable values across instances. PiperOrigin-RevId: 238316564 -- 56dec1d1e37fb2a02aa10d7c81bcd78f8486c093 by Eric Fiselier <ericwf@google.com>: Add SFINAE to absl::optional::optional(in_place_t, Args...) This constructor previously didn't have SFINAE because the SFINAE acted badly when Clang was trying to figure out what special members to declare. Specifically, while considering copy constructors it would attempt to call `optional(in_place_t) [ with Args = <> ]`, which evaluated `is_constructible<T>`, which shouldn't have been evaluated. This patch avoids the eager SFINAE bug by deducing the in_place_t tag and short-circuting the SFINAE if the argument passed is not exactly in_place_t. I fixed the same bug in libc++ in the same way. PiperOrigin-RevId: 238290810 -- ffe6d087df495f7f990c89b0a4e1f1664c2c4f9d by Jon Cohen <cohenjon@google.com>: Remove absl_internal_blah names form CMake.

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.

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.

The single source of truth is now absl/copts/copts.py The way this works goes something like this: copts.py acts as the configuration file. We use python because unlike JSON it allows comments. It has two maps in it: one from names to external flags, and one from names to internal flags. generate_copts.py imports the maps and loops through them to write GENERATED_copts.bzl and GENERATED_AbseilCopts.cmake AbseilConfigureCopts.cmake and configure_copts.bzl import their respective copts args and set the platform-appropriate copts into ABSL_DEFAULT_COPTS, ABSL_TEST_COPTS, ABSL_EXCEPTIONS_FLAG, and ABSL_EXCEPTIONS_LINKOPTS For Bazel, each BUILD file load()s configure_copts.bzl For CMake, AbseilHelpers.cmake include()s AbseilConfigureCopts.cmake to get the final copts and both inserts them as needed into legacy target rules and also makes them available to the rest of our CMakeLists.txt file. 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. That's also not as idiomatic -- CMake tends to use directory scope where globals set at a higher level CMakeLists.txt file are used in the subdirectory CMakeLists.txt files.

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.

It's impossible to specifically pull out MSVC 2017 -dbg modes because there's no way for Bazel to know when version of MSVC is being used -- you tell Bazel the directory where the MSVC tools live, not which version of MSVC tools to use. Thus the best we can do is switch on _DEBUG, which is set whenever the debug runtime is selected with the /MDd build flag, as in Bazel -dbg modes.

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.
