This hardens the implementation against ODR violations where info pointers are crossing dynamic library boundaries which are privately loaded. PiperOrigin-RevId: 370673045 -- 712dba768e66ee2ba85d6010829c617cd2af6ba7 by Martijn Vels <mvels@google.com>: Intrument Cord::operator= for Cordz PiperOrigin-RevId: 370659149 -- c0b347a2289e151b72680269332e264b8fa989c0 by Matt Kulukundis <kfm@google.com>: Fix test guards for ABSL_ATTRIBUTE_RETURNS_NONNULL PiperOrigin-RevId: 370594807 -- c2bedaa3472ef223f907de2604f9b9b58852ec5f by Martijn Vels <mvels@google.com>: Add new Cordz instrumentation on GetAppendRegion.

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. Add further ABSL_NAMESPACE_BEGIN and _END annotation macros to files in Abseil.

PiperOrigin-RevId: 264430409 -- 292e6b9e08fa689e8400d7f2db94cbcab29d5889 by CJ Johnson <johnsoncj@google.com>: Removes use of aligned_storage in FixedArray and InlinedVector in favor of aligned char buffers. PiperOrigin-RevId: 264385559 -- aa0b19ad11ae5702022feee0e2e6434cfb28c9e9 by Derek Mauro <dmauro@google.com>: Make the unit tests for absl::any, absl::optional, and absl::variant no-ops when these types are just aliases for the corresponding std:: types. We have no way to fix standard library implementation bugs, so don't bother working around them. Also disable the corresponding exception-safety tests as well when exceptions are not enabled.

PiperOrigin-RevId: 221145354 -- afd4d7c106919708004e06aeea068a57c28aec44 by Derek Mauro <dmauro@google.com>: Update the debugging log message in CallOnceImpl() PiperOrigin-RevId: 221103254 -- 0b9dace8b88113777bf26a6d38f9bc0bcaf053a1 by Abseil Team <absl-team@google.com>: Workaround an MSVC 2015 bug in compile-time initialization. PiperOrigin-RevId: 220871483 -- ea0a3854511ed26beab827e5a5113766b334db86 by Marek Gilbert <mcg@google.com>: Fix ABSL_HAVE_THREAD_LOCAL when compiling for iOS 8 with Xcode 10. Xcode 10 has moved the check for thread_local to a link time, so clang reports __has_feature(cxx_thread_local) but then linking fails with messages like this: ld: targeted OS version does not support use of thread local variables PiperOrigin-RevId: 220815885 -- 485b6876c158c3dcf37eb32d7e512242d5d4ecc6 by Greg Falcon <gfalcon@google.com>: Make the absl::c_set_xxxx() algorithms refuse to compile when passed an unordered collection from std:: or absl::. These algorithms operate on sorted sequences; passing an unordered container to them is nearly certainly a bug. This change is technically an API break, but it only breaks incorrect code. We could try to be more clever and detect unordered collections from other libraries, but false positives will break legal code, and this would constitute an API break Abseil cannot afford. PiperOrigin-RevId: 220794190 -- c47cff7f9cc70a4c1604eee0131af552f40e46d6 by Jon Cohen <cohenjon@google.com>: MSVC 2017's STL throws a Structured Exception (not a C++ exception, essentially equivalent to SIGSEGV) when variant::emplace calls a throwing constructor when using the debug multithreaded MSVC runtime DLL. This manifests in dbg mode in Bazel builds. Disable tests which trigger this bug. 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. See https://msdn.microsoft.com/en-us/library/b0084kay.aspx ctrl-f "_DEBUG" PiperOrigin-RevId: 220706161 -- 43993d4af309d92f4ebff38391dcc245f154ecc7 by Shaindel Schwartz <shaindel@google.com>: Internal change PiperOrigin-RevId: 220688429 -- 2448802972dcc261af153af464f2b022ef54a2a9 by Abseil Team <absl-team@google.com>: Speed up operator* for uint128 in WIN64.
