The offset is computed based on the assumption that the `value_` data member is placed directly after the impl_ data member in Flag<T>.

2020-03-09 UWP doesn't allow reading regkeys (#594)Augusto Righetto1-0/+7
* UWP doesn't allow reading regkeys. Unfortunately, UWP also doesn't offer an API for returning nominal processor frequency at this moment. Other options would require apps depending on abseil-cpp to be packaged with extra manifest data or libraries for bridging platforms. This change pushes the unsupported APIs accessing the registry behind a define guard. This define guard makes GetNominalCPUFrequency to compile and run as usual on desktop, but it will return the value 1.0 on UWP Apps (Store). * Using WINAPI_FAMILY_PARTITION family of macros for detecting when building for UWP or Desktop. * Simplifying comment to please the lint tool.

This is currently experimental and unsupported. This CL does a few things: 1. Adds the ABSL_DLL macro to any class holding a static data member, or to global constants in headers. 2. Adds a whitelist of all files in the DLL and all the build targets that are conglomerated into the DLL. 3. When BUILD_SHARED_LIBS is specified, any build target that would be in the DLL still exists, but we swap out all of it's dependencies so it just depends on abseil_dll PiperOrigin-RevId: 291192055 -- 5e888cd6f2a7722805d41f872108a03a84e421c7 by Mark Barolak <mbar@google.com>: Move absl/strings/internal/escaping.{cc,h} into internal build targets.

Static initializers are problematic for a number of reasons. Not only are they responsible for the static initialization order fiasco, but they are in the critical path during program startup. For these reasons, the Google C++ style guide strongly discourages them (and forbids them when they are not trivially destructible), and Chromium even has a test forbidding them. https://google.github.io/styleguide/cppguide.html#Static_and_Global_Variables https://chromium.googlesource.com/chromium/src.git/+/master/docs/static_initializers.md http://neugierig.org/software/chromium/notes/2011/08/static-initializers.html PiperOrigin-RevId: 289458677 -- c869362f6bb7a872314f74750d38d81bdaa73f95 by Greg Falcon <gfalcon@google.com>: Step 2 of 2 to fix our CCTZ fork to respect inline namespaces.

PiperOrigin-RevId: 289454407 -- fdb3474d76c2ee0371ccdf7593a78137c03a3f58 by Greg Falcon <gfalcon@google.com>: Step 1 of 2 to fix our CCTZ fork to respect inline namespaces. CCTZ uses a linker flag to simulate weak symbol support in MSVC. This takes the form of a #pragma that includes the mangled names of two types: the symbol to treat as weak, and the symbol to use as its default value if no override is provided. When Abseil is configured to use inline namespaces, the mangled names of these symbols change, and the pragma should change to reflect that. Fortunately for us, MSVC name mangling is simple enough that we can generate the needed string literals in the preprocessor. This CL introduces the new macros; the uses will be introduced in a follow-up CL.

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.

The atomic load of 'control' in the #ifndef NDEBUG block does not need std::memory_order_acquire. It can use std::memory_order_relaxed. The atomic compare_exchange_strong of 'control' does not need std::memory_order_acquire in the success case. It can use std::memory_order_relaxed.

ResetThreadIdentity is only called by NewThreadIdentity. NewThreadIdentity is only called by CreateThreadIdentity. CreateThreadIdentity calls PerThreadSem::Init, which initializes identity->waiter_state, immediately after calling NewThreadIdentity.

The f->header.magic check in LowLevelAlloc::Free() is redundant, because AddToFreeList() will immediately perform the same check. Also fix a typo in the comment that documents the lock requirements for Next(). The comment should say "L >= arena->mu", which is equivalent to EXCLUSIVE_LOCKS_REQUIRED(arena->mu).

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.

Immediately after waking up (when futex wait returns), the current thread tries to become idle doing bunch of memory loads and a branch. Problem is that there is a good chance that we woke up due to a wakeup, especially for actively used threads. For such wakeups, calling MaybeBecomeIdle() would be a waste of cycles. Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup. For idle threads the net effect should be the same. For active, threads this will be more efficient. Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the current thread will try to become idle before sleeping. This should result in more accurate idleness and more efficient release of thread resources.

On this platform, constexpr static init sometimes happens after dynamic init =/. When it does, we should not zero hook_ (overwriting the value written there by dynamic init); instead we should leave it alone.
