This isn't testing behavior related to the library, and MSVC warns about it in opt mode. PiperOrigin-RevId: 285220804 -- 68b015491f0dbf1ab547994673281abd1f34cd4b by Gennadiy Rozental <rogeeff@google.com>: This CL introduces following changes to the class FlagImpl: * We eliminate the CommandLineFlagLocks struct. Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately. * CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now. * Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call. * We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced. PiperOrigin-RevId: 285132636 -- ed45d118fb818969eb13094cf7827c885dfc562c by Tom Manshreck <shreck@google.com>: Change null-term* (and nul-term*) to NUL-term* in comments PiperOrigin-RevId: 285036610 -- 729619017944db895ce8d6d29c1995aa2e5628a5 by Derek Mauro <dmauro@google.com>: Use the Posix implementation of thread identity on MinGW. Some versions of MinGW suffer from thread_local bugs. PiperOrigin-RevId: 285022920 -- 39a25493503c76885bc3254c28f66a251c5b5bb0 by Greg Falcon <gfalcon@google.com>: Implementation detail change.

We should ideally use the std forms in more cases, but branching when our workarounds fail is simpler to maintain.

PiperOrigin-RevId: 277498394 -- b23757b0747c64634d2d701433782c969effef19 by Abseil Team <absl-team@google.com>: Fix https://github.com/abseil/abseil-cpp/issues/394. PiperOrigin-RevId: 277491405 -- 54c75b8b29813531c52d67cf0ba7063baae4a4f3 by Abseil Team <absl-team@google.com>: Fix comment typos: waker => waiter. PiperOrigin-RevId: 277376952 -- 874eeaa3b3af808fc88b6355245f643674f5e36e by Abseil Team <absl-team@google.com>: Don't use atomic ops on waiter and wakeup counts in CONDVAR waiter mode. Just guard the waiter and wakeup counts with the mutex. This eliminates the race. Also fix a typo in the error message for pthread_cond_timedwait. PiperOrigin-RevId: 277366017 -- ce8c9a63109214519b5a7eaecef2c663c4d566df by Greg Falcon <gfalcon@google.com>: Implement the config options for our four main C++ forward compatibility types. These options control whether the names `any`, `optional`, `string_view`, and `variant` in namespace `absl` are aliases to the corresponding C++17 types in namespace `std`. By default, we continue to auto-detect the configuration of the compiler being run. These options are not intended to be modified on the command line (as -D flags, say). Instead, the options.h file can be modified by distributors of Abseil (e.g., binary packagers, maintainers of local copies of Abseil, etc.) Changing options will change Abseil in an ODR sense. Any program must only link in a single version of Abseil. Linking libraries that use Abseil configured with different options is an error: there is no ABI compatibility guarantee when linking different configurations, even if the Abseil versions used are otherwise exactly identical. PiperOrigin-RevId: 277364298 -- 5ed3ad42ae43a05862070f92f9ffd07f5c1f2b81 by Chris Kennelly <ckennelly@google.com>: Suppress -Wimplicit-int-float-conversion. On recent builds of Clang, this is an error/warning. PiperOrigin-RevId: 277346168 -- 9b9b0055243c705189bb27d912e6d45a7789cdee by Eric Fiselier <ericwf@google.com>: Allow building Abseil as a shared library with CMake. By default CMake's `add_library` creates the target as a static library. However, users can override the default using the builtin CMake option -DBUILD_SHARED_LIBS=ON. This changes Abseil's CMake to respect this configuration option by removing the explicit `STATIC` in our usages of `add_library`. PiperOrigin-RevId: 277337753 -- 63a8b7b8ede3a9d851916929d6b8537f4f2508ca by Abseil Team <absl-team@google.com>: Improve AlphaNum Hex performance by using absl::numbers_internal::FastHexToBufferZeroPad16.

PiperOrigin-RevId: 277301500 -- 5373f3737894ba9b8481e95e5f58c7957c00d26a by Chris Kennelly <ckennelly@google.com>: For internal reasons, loosen visibility restrictions of `//absl/base:malloc_internal`. As an internal-namespace interface, this module remains unsupported. We reserve the right to change, delete, or re-restrict visibility to this target at any time. PiperOrigin-RevId: 277118689 -- 44e4f6655e05393a375d09b3625c192b1fde5909 by Abseil Team <absl-team@google.com>: Fix error in example civil day comment. PiperOrigin-RevId: 277103315 -- 7657392b4ce48469106f11cdb952a0bc76a28df3 by Abseil Team <absl-team@google.com>: Internal change PiperOrigin-RevId: 277056076 -- c75bda76f40b01fa249b75b5a70c1f5907e56c76 by Abseil Team <absl-team@google.com>: Suppress lifetime constant-initialization tests when building with MSVC versions > 19.0. These are broken due to non-compliant initialization order in these versions: https://developercommunity.visualstudio.com/content/problem/336946/class-with-constexpr-constructor-not-using-static.html We don't know when Microsoft will fix this bug.

PiperOrigin-RevId: 276694032 -- a9426af8cbd4c3a8f9053e7446c821852e41ff61 by Jorg Brown <jorg@google.com>: Stop including kern/OSByteOrder.h in order to support __APPLE__ Apple compiles with clang now anyway, and clang has support for the built-in compiler swap functions that are much faster than any function call to the OS. PiperOrigin-RevId: 276625231 -- df974be5aa5b4dc1b09c356cb8816edfc7867e63 by Jorg Brown <jorg@google.com>: Fix the build for Android x86-64 builds, where __SSE4_2__ is defined but _bswap64 is not. PiperOrigin-RevId: 276542642 -- d99dc092b3a5ad17643005e55f3b3cb6b9187ccc by Jorg Brown <jorg@google.com>: Remove a byteswap from the non-SSE path of FastHexToBufferZeroPad16 Remove the need for including absl/base/internal/endian.h from the SSE case (since if we have the Intel SSE intrinsics, then clearly we also have the Intel Byte-Swap intrinsics.) PiperOrigin-RevId: 276532608 -- d67b106dc930d8558810ae3983613bb2ab1e0d36 by Abseil Team <absl-team@google.com>: Use explicit static_cast<double> for int64_t to double conversion This uses an explicit static_cast<double>() in the int64_t to double comparisons in duration.cc's SafeAddRepHi. This satisfies clang's -Wimplicit-int-to-float-conversion warning (with https://reviews.llvm.org/D64666). This may also make it easier for humans to realize that the comparison is happening between two floating point double precision values. It should have no impact on the behavior or generated code. Tested: No behavior change PiperOrigin-RevId: 276529211 GitOrigin-RevId: 2f49cb9009386bc67bf54a2908c8720b749c8b7f Change-Id: I71e0781893ce219960b8290d54b20532779cb0ff

PiperOrigin-RevId: 263774164 -- 19e09a7ce8a0aac0a7d534e1799e4d73b63a1bb5 by Abseil Team <absl-team@google.com>: Update iter.position when moving up the tree in rebalance_after_delete. This field isn't read after the first iteration in rebalance_after_delete, and I think it's not a correctness issue, but it is read in try_merge_or_rebalance and potentially affects rebalancing decisions so it can affect performance. There's also an extremely unlikely potential for undefined behavior due to signed integer overflow since this field is only ever incremented in try_merge_or_rebalance (and position is an int). Basically though, I just don't think it makes sense to have this invalid iterator floating around here.
