Export of internal Abseil changes -- 2ba0e41a21fbdab36b2f4f3b0dd4b112bd788604 by Derek Mauro <dmauro@google.com>: Remove the include of <intsafe.h>, which is missing on some versions of MinGW. DWORD is easily replaced by uint32_t. PiperOrigin-RevId: 282576177 -- 238fd41114b3e83fcb91d2afe1e6dcce7cfd53b0 by Samuel Benzaquen <sbenza@google.com>: Remove assertion in erase(iterator) that tries to use the comparator. Add missing this-> qualifier. Fix bug where node elements are not being destroyed properly. PiperOrigin-RevId: 282427096 -- 6b9446e3b38ed97451c010933e86a572ab659ab2 by Derek Mauro <dmauro@google.com>: Improves/fixes feature detection in thread_identity Only use ABSL_PER_THREAD_TLS_KEYWORD when it is supported (previously on some platforms it evaluated to nothing, which completely breaks everything), but prefer it to thread_local since benchmarks indicate it is slightly faster in this critical code path. Disable the calls to pthread_sigmask on MinGW where it is not supported.

The repository contains the Abseil C++ library code. Abseil is an open-source collection of C++ code (compliant to C++11) designed to augment the C++ standard library.
Abseil is an open-source collection of C++ library code designed to augment the C++ standard library. The Abseil library code is collected from Google's own C++ code base, has been extensively tested and used in production, and is the same code we depend on in our daily coding lives.
In some cases, Abseil provides pieces missing from the C++ standard; in others, Abseil provides alternatives to the standard for special needs we've found through usage in the Google code base. We denote those cases clearly within the library code we provide you.
Abseil is not meant to be a competitor to the standard library; we've just found that many of these utilities serve a purpose within our code base, and we now want to provide those resources to the C++ community as a whole.
If you want to just get started, make sure you at least run through the Abseil Quickstart. The Quickstart contains information about setting up your development environment, downloading the Abseil code, running tests, and getting a simple binary working.
Bazel is the official build system for Abseil, which is supported on most major platforms (Linux, Windows, macOS, for example) and compilers. See the quickstart for more information on building Abseil using the Bazel build system.
If you require CMake support, please check the CMake build instructions.
Abseil contains the following C++ library components:
base Abseil Fundamentals base library contains initialization code and other code which all other Abseil code depends on. Code within base may not depend on any other code (other than the C++ standard library).algorithm algorithm library contains additions to the C++ <algorithm> library and container-based versions of such algorithms.container container library contains additional STL-style containers, including Abseil's unordered “Swiss table” containers.debugging debugging library contains code useful for enabling leak checks, and stacktrace and symbolization utilities.hash hash library contains the hashing framework and default hash functor implementations for hashable types in Abseil.memory memory library contains C++11-compatible versions of std::make_unique() and related memory management facilities.meta meta library contains C++11-compatible versions of type checks available within C++14 and C++17 versions of the C++ <type_traits> library.numeric numeric library contains C++11-compatible 128-bit integers.strings strings library contains a variety of strings routines and utilities, including a C++11-compatible version of the C++17 std::string_view type.synchronization synchronization library contains concurrency primitives (Abseil's absl::Mutex class, an alternative to std::mutex) and a variety of synchronization abstractions.time time library contains abstractions for computing with absolute points in time, durations of time, and formatting and parsing time within time zones.types types library contains non-container utility types, like a C++11-compatible version of the C++17 std::optional type.utility utility library contains utility and helper code.The Abseil C++ library is licensed under the terms of the Apache license. See LICENSE for more information.
