// flag data, and abstractions to create, get and set such flag data.
//
// It is important to note that this type is **unspecified** (an implementation
// detail) and you do not construct or manipulate actual `absl::Flag<T>`
// instances. Instead, you define and declare flags using the
// `ABSL_FLAG()` and `ABSL_DECLARE_FLAG()` macros, and get and set flag values
// using the `absl::GetFlag()` and `absl::SetFlag()` functions.

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.

// Flag
//
// An `absl::Flag` holds a command-line flag value, providing a runtime
// parameter to a binary. Such flags should be defined in the global namespace
// and (preferably) in the module containing the binary's `main()` function.
//
// You should not construct and cannot use the `absl::Flag` type directly;
// instead, you should declare flags using the `ABSL_DECLARE_FLAG()` macro
// within a header file, and define your flag using `ABSL_FLAG()` within your
// header's associated `.cc` file. Such flags will be named `FLAGS_name`.
//
// Example:
//
// .h file
//
// // Declares usage of a flag named "FLAGS_count"
// ABSL_DECLARE_FLAG(int, count);
//
// .cc file
//
// // Defines a flag named "FLAGS_count" with a default `int` value of 0.
// ABSL_FLAG(int, count, 0, "Count of items to process");
//
// No public methods of `absl::Flag<T>` are part of the Abseil Flags API.

// MSVC debug builds do not implement initialization with constexpr constructors
// correctly. To work around this we add a level of indirection, so that the
// class `absl::Flag` contains an `internal::Flag*` (instead of being an alias
// to that class) and dynamically allocates an instance when necessary. We also
// forward all calls to internal::Flag methods via trampoline methods. In this
// setup the `absl::Flag` class does not have constructor and virtual methods,
// all the data members are public and thus MSVC is able to initialize it at
// link time. To deal with multiple threads accessing the flag for the first
// time concurrently we use an atomic boolean indicating if flag object is
// initialized. We also employ the double-checked locking pattern where the
// second level of protection is a global Mutex, so if two threads attempt to
// construct the flag concurrently only one wins.
// This solution is based on a recomendation here:

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.

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.

This change separates static flag value type identification from the type specific "vtable" with all the operations specific to value type. This change allows us to do the following: * We can move most of "vtable" implementation from handle header, which will become public soon, into implementation details of Abseil Flag. * We can combine back marshalling ops and general ops into a single vtable routine. They were split previously to facilitate type identification without requiring marshalling routines to be exposed in header. * We do not need to store two vtable pointers. We can now store only one. The static type id can be deduced on request. Overall we are saving 24 bytes per flag according to size_tester run.

// GetFlag()
//
// Returns the value (of type `T`) of an `absl::Flag<T>` instance, by value. Do
// not construct an `absl::Flag<T>` directly and call `absl::GetFlag()`;
// instead, refer to flag's constructed variable name (e.g. `FLAGS_name`).
// Because this function returns by value and not by reference, it is
// thread-safe, but note that the operation may be expensive; as a result, avoid
// `absl::GetFlag()` within any tight loops.
//
// Example:
//
// // FLAGS_count is a Flag of type `int`
// int my_count = absl::GetFlag(FLAGS_count);
//
// // FLAGS_firstname is a Flag of type `std::string`
// std::string first_name = absl::GetFlag(FLAGS_firstname);

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.

// ABSL_RETIRED_FLAG
//
// Designates the flag (which is usually pre-existing) as "retired." A retired
// flag is a flag that is now unused by the program, but may still be passed on
// the command line, usually by production scripts. A retired flag is ignored
// and code can't access it at runtime.
//
// This macro registers a retired flag with given name and type, with a name
// identical to the name of the original flag you are retiring. The retired
// flag's type can change over time, so that you can retire code to support a
// custom flag type.
//
// This macro has the same signature as `ABSL_FLAG`. To retire a flag, simply
// replace an `ABSL_FLAG` definition with `ABSL_RETIRED_FLAG`, leaving the
// arguments unchanged (unless of course you actually want to retire the flag
// type at this time as well).
//
// `default_value` is only used as a double check on the type. `explanation` is
// unused.
// TODO(rogeeff): Return an anonymous struct instead of bool, and place it into
// the unnamed namespace.
#define ABSL_RETIRED_FLAG(type, flagname, default_value, explanation) \

PiperOrigin-RevId: 287997504 -- 35fb1a893e708031ba4fc0db460875eb0d31820e by Abseil Team <absl-team@google.com>: Enable compile-time enforcement that absl::Substitute patterns to not contain unescaped $ symbols. absl::Substitute already considers unescaped $ symbols undefined behavior and crashes when it's passed them in debug builds. Some code isn't ever built in debug mode, though, and inadvertently used some unescaped $ symbols, which led to surprising results. This change will prevent that problem from happening in the future. PiperOrigin-RevId: 287906643 -- c5762833ebde6d7110bf68041a823b571c238e9e by Gennadiy Rozental <rogeeff@google.com>: Move all the flag data into a single place instead of being split between handle and flag object. After this change CommandLineFlag will not hold any data anymore. And we also do not need to pass the CommandLineFlag around in Abseil Flag implementation to report flag name and location.

Before the change: ABSL_RETIRED_FLAG does not compile when there are competing ctors in the type, even when ABSL_FLAG does. After the change: ABSL_RETIRED_FLAG compiles when ABSL_FLAG does.
