-// Each unique combination of (arity, function_type, num_prebound) where

-// one specialization.  We eventually have to do a similar number of
-// specializations anyways in the implementation (see the Invoker<>,

-// This defines a set of argument wrappers and related factory methods that
-// can be used specify the refcounting and reference semantics of arguments
-// that are bound by the Bind() function in base/bind.h.
-//
-// It also defines a set of simple functions and utilities that people want
-// when using Callback<> and Bind().
-//
-//
-// ARGUMENT BINDING WRAPPERS
-//
-// The wrapper functions are base::Unretained(), base::Owned(), base::Passed(),
-// base::ConstRef(), and base::IgnoreResult().
-//
-// Unretained() allows Bind() to bind a non-refcounted class, and to disable
-// refcounting on arguments that are refcounted objects.
-//
-// Owned() transfers ownership of an object to the Callback resulting from
-// bind; the object will be deleted when the Callback is deleted.
-//
-// Passed() is for transferring movable-but-not-copyable types (eg. scoped_ptr)
-// through a Callback. Logically, this signifies a destructive transfer of
-// the state of the argument into the target function.  Invoking
-// Callback::Run() twice on a Callback that was created with a Passed()
-// argument will CHECK() because the first invocation would have already

-//
-// ConstRef() allows binding a constant reference to an argument rather
-// than a copy.
-//
-// IgnoreResult() is used to adapt a function or Callback with a return type to
-// one with a void return. This is most useful if you have a function with,
-// say, a pesky ignorable bool return that you want to use with PostTask or
-// something else that expect a Callback with a void return.
-//
-// EXAMPLE OF Unretained():
-//
-//   class Foo {
-//    public:
-//     void func() { cout << "Foo:f" << endl; }
-//   };
-//
-//   // In some function somewhere.
-//   Foo foo;
-//   Closure foo_callback =
-//       Bind(&Foo::func, Unretained(&foo));
-//   foo_callback.Run();  // Prints "Foo:f".
-//
-// Without the Unretained() wrapper on |&foo|, the above call would fail
-// to compile because Foo does not support the AddRef() and Release() methods.
-//
-//
-// EXAMPLE OF Owned():
-//
-//   void foo(int* arg) { cout << *arg << endl }
-//
-//   int* pn = new int(1);
-//   Closure foo_callback = Bind(&foo, Owned(pn));
-//
-//   foo_callback.Run();  // Prints "1"
-//   foo_callback.Run();  // Prints "1"
-//   *n = 2;
-//   foo_callback.Run();  // Prints "2"
-//
-//   foo_callback.Reset();  // |pn| is deleted.  Also will happen when

-//
-// Without Owned(), someone would have to know to delete |pn| when the last
-// reference to the Callback is deleted.
-//
-//
-// EXAMPLE OF ConstRef():
-//
-//   void foo(int arg) { cout << arg << endl }
-//
-//   int n = 1;
-//   Closure no_ref = Bind(&foo, n);
-//   Closure has_ref = Bind(&foo, ConstRef(n));
-//
-//   no_ref.Run();  // Prints "1"
-//   has_ref.Run();  // Prints "1"
-//
-//   n = 2;
-//   no_ref.Run();  // Prints "1"
-//   has_ref.Run();  // Prints "2"
-//
-// Note that because ConstRef() takes a reference on |n|, |n| must outlive all
-// its bound callbacks.
-//
-//
-// EXAMPLE OF IgnoreResult():
-//
-//   int DoSomething(int arg) { cout << arg << endl; }
-//
-//   // Assign to a Callback with a void return type.
-//   Callback<void(int)> cb = Bind(IgnoreResult(&DoSomething));
-//   cb->Run(1);  // Prints "1".
-//
-//   // Prints "1" on |ml|.
-//   ml->PostTask(FROM_HERE, Bind(IgnoreResult(&DoSomething), 1);
-//
-//
-// EXAMPLE OF Passed():
-//
-//   void TakesOwnership(scoped_ptr<Foo> arg) { }
-//   scoped_ptr<Foo> CreateFoo() { return scoped_ptr<Foo>(new Foo()); }
-//
-//   scoped_ptr<Foo> f(new Foo());
-//
-//   // |cb| is given ownership of Foo(). |f| is now NULL.

-//   cb.Run();  // This CHECK()s since Foo() already been used once.
-//
-// Passed() is particularly useful with PostTask() when you are transferring

-// http://stackoverflow.com/questions/1966362/sfinae-to-check-for-inherited-member-functions
-//
-// The last link in particular show the method used below.
-//
-// For SFINAE to work with inherited methods, we need to pull some extra tricks
-// with multiple inheritance.  In the more standard formulation, the overloads
-// of Check would be:
-//
-//   template <typename C>
-//   Yes NotTheCheckWeWant(Helper<&C::TargetFunc>*);
-//
-//   template <typename C>
-//   No NotTheCheckWeWant(...);
-//
-//   static const bool value = sizeof(NotTheCheckWeWant<T>(0)) == sizeof(Yes);
-//
-// The problem here is that template resolution will not match
-// C::TargetFunc if TargetFunc does not exist directly in C.  That is, if
-// TargetFunc in inherited from an ancestor, &C::TargetFunc will not match,
-// |value| will be false.  This formulation only checks for whether or
-// not TargetFunc exist directly in the class being introspected.
-//
-// To get around this, we play a dirty trick with multiple inheritance.
-// First, We create a class BaseMixin that declares each function that we
-// want to probe for.  Then we create a class Base that inherits from both T
-// (the class we wish to probe) and BaseMixin.  Note that the function
-// signature in BaseMixin does not need to match the signature of the function
-// we are probing for; thus it's easiest to just use void(void).
-//
-// Now, if TargetFunc exists somewhere in T, then &Base::TargetFunc has an
-// ambiguous resolution between BaseMixin and T.  This lets us write the
-// following:
-//
-//   template <typename C>
-//   No GoodCheck(Helper<&C::TargetFunc>*);
-//
-//   template <typename C>
-//   Yes GoodCheck(...);
-//
-//   static const bool value = sizeof(GoodCheck<Base>(0)) == sizeof(Yes);
-//
-// Notice here that the variadic version of GoodCheck() returns Yes here
-// instead of No like the previous one. Also notice that we calculate |value|
-// by specializing GoodCheck() on Base instead of T.
-//
-// We've reversed the roles of the variadic, and Helper overloads.
-// GoodCheck(Helper<&C::TargetFunc>*), when C = Base, fails to be a valid
-// substitution if T::TargetFunc exists. Thus GoodCheck<Base>(0) will resolve
-// to the variadic version if T has TargetFunc.  If T::TargetFunc does not
-// exist, then &C::TargetFunc is not ambiguous, and the overload resolution
-// will prefer GoodCheck(Helper<&C::TargetFunc>*).
-//
-// This method of SFINAE will correctly probe for inherited names, but it cannot
-// typecheck those names.  It's still a good enough sanity check though.
-//
-// Works on gcc-4.2, gcc-4.4, and Visual Studio 2008.
-//
-// TODO(ajwong): Move to ref_counted.h or template_util.h when we've vetted
-// this works well.

-// PassedWrapper is a copyable adapter for a scoper that ignores const.

-// It is needed to get around the fact that Bind() takes a const reference to
-// all its arguments.  Because Bind() takes a const reference to avoid
-// unnecessary copies, it is incompatible with movable-but-not-copyable
-// types; doing a destructive "move" of the type into Bind() would violate
-// the const correctness.
-//
-// This conundrum cannot be solved without either C++11 rvalue references or
-// a O(2^n) blowup of Bind() templates to handle each combination of regular
-// types and movable-but-not-copyable types.  Thus we introduce a wrapper type
-// that is copyable to transmit the correct type information down into
-// BindState<>. Ignoring const in this type makes sense because it is only
-// created when we are explicitly trying to do a destructive move.
-//
-// Two notes:
-//  1) PassedWrapper supports any type that has a "Pass()" function.
-//     This is intentional. The whitelisting of which specific types we
-//     support is maintained by CallbackParamTraits<>.

-// Introduction
-// -----------------------------------------------------------------------------
-//
-// The templated Callback class is a generalized function object. Together
-// with the Bind() function in bind.h, they provide a type-safe method for
-// performing partial application of functions.
-//
-// Partial application (or "currying") is the process of binding a subset of
-// a function's arguments to produce another function that takes fewer
-// arguments. This can be used to pass around a unit of delayed execution,
-// much like lexical closures are used in other languages. For example, it
-// is used in Chromium code to schedule tasks on different MessageLoops.
-//
-// A callback with no unbound input parameters (base::Callback<void(void)>)
-// is called a base::Closure. Note that this is NOT the same as what other
-// languages refer to as a closure -- it does not retain a reference to its
-// enclosing environment.
-//
-// MEMORY MANAGEMENT AND PASSING
-//
-// The Callback objects themselves should be passed by const-reference, and
-// stored by copy. They internally store their state via a refcounted class
-// and thus do not need to be deleted.
-//
-// The reason to pass via a const-reference is to avoid unnecessary
-// AddRef/Release pairs to the internal state.
-//
-//
-// -----------------------------------------------------------------------------
-// Quick reference for basic stuff
-// -----------------------------------------------------------------------------
-//
-// BINDING A BARE FUNCTION
-//
-//   int Return5() { return 5; }
-//   base::Callback<int(void)> func_cb = base::Bind(&Return5);
-//   LOG(INFO) << func_cb.Run();  // Prints 5.
-//
-// BINDING A CLASS METHOD
-//
-//   The first argument to bind is the member function to call, the second is
-//   the object on which to call it.
-//
-//   class Ref : public base::RefCountedThreadSafe<Ref> {
-//    public:
-//     int Foo() { return 3; }
-//     void PrintBye() { LOG(INFO) << "bye."; }
-//   };
-//   scoped_refptr<Ref> ref = new Ref();
-//   base::Callback<void(void)> ref_cb = base::Bind(&Ref::Foo, ref);
-//   LOG(INFO) << ref_cb.Run();  // Prints out 3.
-//
-//   By default the object must support RefCounted or you will get a compiler
-//   error. If you're passing between threads, be sure it's
-//   RefCountedThreadSafe! See "Advanced binding of member functions" below if
-//   you don't want to use reference counting.
-//
-// RUNNING A CALLBACK
-//
-//   Callbacks can be run with their "Run" method, which has the same
-//   signature as the template argument to the callback.
-//
-//   void DoSomething(const base::Callback<void(int, std::string)>& callback) {
-//     callback.Run(5, "hello");
-//   }
-//
-//   Callbacks can be run more than once (they don't get deleted or marked when
-//   run). However, this precludes using base::Passed (see below).
-//
-//   void DoSomething(const base::Callback<double(double)>& callback) {
-//     double myresult = callback.Run(3.14159);
-//     myresult += callback.Run(2.71828);
-//   }
-//
-// PASSING UNBOUND INPUT PARAMETERS
-//
-//   Unbound parameters are specified at the time a callback is Run(). They are
-//   specified in the Callback template type:
-//
-//   void MyFunc(int i, const std::string& str) {}
-//   base::Callback<void(int, const std::string&)> cb = base::Bind(&MyFunc);
-//   cb.Run(23, "hello, world");
-//
-// PASSING BOUND INPUT PARAMETERS
-//
-//   Bound parameters are specified when you create thee callback as arguments
-//   to Bind(). They will be passed to the function and the Run()ner of the
-//   callback doesn't see those values or even know that the function it's
-//   calling.
-//
-//   void MyFunc(int i, const std::string& str) {}
-//   base::Callback<void(void)> cb = base::Bind(&MyFunc, 23, "hello world");
-//   cb.Run();
-//
-//   A callback with no unbound input parameters (base::Callback<void(void)>)
-//   is called a base::Closure. So we could have also written:
-//
-//   base::Closure cb = base::Bind(&MyFunc, 23, "hello world");
-//
-//   When calling member functions, bound parameters just go after the object
-//   pointer.
-//
-//   base::Closure cb = base::Bind(&MyClass::MyFunc, this, 23, "hello world");
-//
-// PARTIAL BINDING OF PARAMETERS
-//
-//   You can specify some parameters when you create the callback, and specify
-//   the rest when you execute the callback.
-//
-//   void MyFunc(int i, const std::string& str) {}
-//   base::Callback<void(const std::string&)> cb = base::Bind(&MyFunc, 23);
-//   cb.Run("hello world");
-//
-//   When calling a function bound parameters are first, followed by unbound
-//   parameters.
-//
-//
-// -----------------------------------------------------------------------------
-// Quick reference for advanced binding
-// -----------------------------------------------------------------------------
-//
-// BINDING A CLASS METHOD WITH WEAK POINTERS
-//
-//   base::Bind(&MyClass::Foo, GetWeakPtr());
-//
-//   The callback will not be run if the object has already been destroyed.
-//   DANGER: weak pointers are not threadsafe, so don't use this
-//   when passing between threads!
-//
-// BINDING A CLASS METHOD WITH MANUAL LIFETIME MANAGEMENT
-//
-//   base::Bind(&MyClass::Foo, base::Unretained(this));
-//
-//   This disables all lifetime management on the object. You're responsible
-//   for making sure the object is alive at the time of the call. You break it,
-//   you own it!
-//
-// BINDING A CLASS METHOD AND HAVING THE CALLBACK OWN THE CLASS
-//
-//   MyClass* myclass = new MyClass;
-//   base::Bind(&MyClass::Foo, base::Owned(myclass));
-//
-//   The object will be deleted when the callback is destroyed, even if it's
-//   not run (like if you post a task during shutdown). Potentially useful for
-//   "fire and forget" cases.
-//
-// IGNORING RETURN VALUES
-//
-//   Sometimes you want to call a function that returns a value in a callback
-//   that doesn't expect a return value.
-//
-//   int DoSomething(int arg) { cout << arg << endl; }
-//   base::Callback<void<int>) cb =
-//       base::Bind(base::IgnoreResult(&DoSomething));
-//
-//
-// -----------------------------------------------------------------------------
-// Quick reference for binding parameters to Bind()
-// -----------------------------------------------------------------------------
-//
-// Bound parameters are specified as arguments to Bind() and are passed to the
-// function. A callback with no parameters or no unbound parameters is called a
-// Closure (base::Callback<void(void)> and base::Closure are the same thing).
-//
-// PASSING PARAMETERS OWNED BY THE CALLBACK
-//
-//   void Foo(int* arg) { cout << *arg << endl; }
-//   int* pn = new int(1);
-//   base::Closure foo_callback = base::Bind(&foo, base::Owned(pn));
-//
-//   The parameter will be deleted when the callback is destroyed, even if it's
-//   not run (like if you post a task during shutdown).
-//
-// PASSING PARAMETERS AS A scoped_ptr
-//
-//   void TakesOwnership(scoped_ptr<Foo> arg) {}
-//   scoped_ptr<Foo> f(new Foo);
-//   // f becomes null during the following call.
-//   base::Closure cb = base::Bind(&TakesOwnership, base::Passed(&f));
-//
-//   Ownership of the parameter will be with the callback until the it is run,
-//   when ownership is passed to the callback function. This means the callback
-//   can only be run once. If the callback is never run, it will delete the
-//   object when it's destroyed.
-//
-// PASSING PARAMETERS AS A scoped_refptr
-//
-//   void TakesOneRef(scoped_refptr<Foo> arg) {}
-//   scoped_refptr<Foo> f(new Foo)
-//   base::Closure cb = base::Bind(&TakesOneRef, f);
-//
-//   This should "just work." The closure will take a reference as long as it
-//   is alive, and another reference will be taken for the called function.
-//
-// PASSING PARAMETERS BY REFERENCE
-//
-//   Const references are *copied* unless ConstRef is used. Example:
-//
-//   void foo(const int& arg) { printf("%d %p\n", arg, &arg); }
-//   int n = 1;
-//   base::Closure has_copy = base::Bind(&foo, n);
-//   base::Closure has_ref = base::Bind(&foo, base::ConstRef(n));
-//   n = 2;
-//   foo(n);                        // Prints "2 0xaaaaaaaaaaaa"
-//   has_copy.Run();                // Prints "1 0xbbbbbbbbbbbb"
-//   has_ref.Run();                 // Prints "2 0xaaaaaaaaaaaa"
-//
-//   Normally parameters are copied in the closure. DANGER: ConstRef stores a
-//   const reference instead, referencing the original parameter. This means
-//   that you must ensure the object outlives the callback!
-//
-//
-// -----------------------------------------------------------------------------
-// Implementation notes
-// -----------------------------------------------------------------------------
-//
-// WHERE IS THIS DESIGN FROM:
-//
-// The design Callback and Bind is heavily influenced by C++'s
-// tr1::function/tr1::bind, and by the "Google Callback" system used inside
-// Google.
-//
-//
-// HOW THE IMPLEMENTATION WORKS:
-//
-// There are three main components to the system:
-//   1) The Callback classes.
-//   2) The Bind() functions.
-//   3) The arguments wrappers (e.g., Unretained() and ConstRef()).
-//
-// The Callback classes represent a generic function pointer. Internally,
-// it stores a refcounted piece of state that represents the target function
-// and all its bound parameters.  Each Callback specialization has a templated
-// constructor that takes an BindState<>*.  In the context of the constructor,
-// the static type of this BindState<> pointer uniquely identifies the
-// function it is representing, all its bound parameters, and a Run() method
-// that is capable of invoking the target.
-//
-// Callback's constructor takes the BindState<>* that has the full static type
-// and erases the target function type as well as the types of the bound
-// parameters.  It does this by storing a pointer to the specific Run()
-// function, and upcasting the state of BindState<>* to a
-// BindStateBase*. This is safe as long as this BindStateBase pointer
-// is only used with the stored Run() pointer.
-//
-// To BindState<> objects are created inside the Bind() functions.
-// These functions, along with a set of internal templates, are responsible for
-//
-//  - Unwrapping the function signature into return type, and parameters
-//  - Determining the number of parameters that are bound
-//  - Creating the BindState storing the bound parameters
-//  - Performing compile-time asserts to avoid error-prone behavior
-//  - Returning an Callback<> with an arity matching the number of unbound
-//    parameters and that knows the correct refcounting semantics for the
-//    target object if we are binding a method.
-//
-// The Bind functions do the above using type-inference, and template
-// specializations.
-//
-// By default Bind() will store copies of all bound parameters, and attempt
-// to refcount a target object if the function being bound is a class method.
-// These copies are created even if the function takes parameters as const
-// references. (Binding to non-const references is forbidden, see bind.h.)
-//
-// To change this behavior, we introduce a set of argument wrappers
-// (e.g., Unretained(), and ConstRef()).  These are simple container templates
-// that are passed by value, and wrap a pointer to argument.  See the
-// file-level comment in base/bind_helpers.h for more info.
-//
-// These types are passed to the Unwrap() functions, and the MaybeRefcount()
-// functions respectively to modify the behavior of Bind().  The Unwrap()
-// and MaybeRefcount() functions change behavior by doing partial
-// specialization based on whether or not a parameter is a wrapper type.
-//
-// ConstRef() is similar to tr1::cref.  Unretained() is specific to Chromium.
-//
-//
-// WHY NOT TR1 FUNCTION/BIND?
-//
-// Direct use of tr1::function and tr1::bind was considered, but ultimately
-// rejected because of the number of copy constructors invocations involved
-// in the binding of arguments during construction, and the forwarding of
-// arguments during invocation.  These copies will no longer be an issue in
-// C++0x because C++0x will support rvalue reference allowing for the compiler
-// to avoid these copies.  However, waiting for C++0x is not an option.
-//
-// Measured with valgrind on gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5), the
-// tr1::bind call itself will invoke a non-trivial copy constructor three times
-// for each bound parameter.  Also, each when passing a tr1::function, each
-// bound argument will be copied again.
-//
-// In addition to the copies taken at binding and invocation, copying a
-// tr1::function causes a copy to be made of all the bound parameters and
-// state.
-//
-// Furthermore, in Chromium, it is desirable for the Callback to take a
-// reference on a target object when representing a class method call.  This
-// is not supported by tr1.
-//
-// Lastly, tr1::function and tr1::bind has a more general and flexible API.
-// This includes things like argument reordering by use of
-// tr1::bind::placeholder, support for non-const reference parameters, and some
-// limited amount of subtyping of the tr1::function object (e.g.,
-// tr1::function<int(int)> is convertible to tr1::function<void(int)>).
-//
-// These are not features that are required in Chromium. Some of them, such as
-// allowing for reference parameters, and subtyping of functions, may actually
-// become a source of errors. Removing support for these features actually
-// allows for a simpler implementation, and a terser Currying API.
-//
-//
-// WHY NOT GOOGLE CALLBACKS?
-//
-// The Google callback system also does not support refcounting.  Furthermore,
-// its implementation has a number of strange edge cases with respect to type
-// conversion of its arguments.  In particular, the argument's constness must
-// at times match exactly the function signature, or the type-inference might
-// break.  Given the above, writing a custom solution was easier.
-//
-//
-// MISSING FUNCTIONALITY
-//  - Invoking the return of Bind.  Bind(&foo).Run() does not work;
-//  - Binding arrays to functions that take a non-const pointer.
-//    Example:
-//      void Foo(const char* ptr);
-//      void Bar(char* ptr);
-//      Bind(&Foo, "test");
-//      Bind(&Bar, "test");  // This fails because ptr is not const.
-
 namespace base {
 
-// First, we forward declare the Callback class template. This informs the
-// compiler that the template only has 1 type parameter which is the function
-// signature that the Callback is representing.
-//
-// After this, create template specializations for 0-7 parameters. Note that
-// even though the template typelist grows, the specialization still
-// only has one type: the function signature.
-//
-// If you are thinking of forward declaring Callback in your own header file,
-// please include "base/callback_forward.h" instead.

-//
-// Instructions
-// ------------
-//
-// Make a bunch of macros for logging.  The way to log things is to stream
-// things to LOG(<a particular severity level>).  E.g.,
-//
-//   LOG(INFO) << "Found " << num_cookies << " cookies";
-//
-// You can also do conditional logging:
-//
-//   LOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-//
-// The CHECK(condition) macro is active in both debug and release builds and
-// effectively performs a LOG(FATAL) which terminates the process and
-// generates a crashdump unless a debugger is attached.
-//
-// There are also "debug mode" logging macros like the ones above:
-//
-//   DLOG(INFO) << "Found cookies";
-//
-//   DLOG_IF(INFO, num_cookies > 10) << "Got lots of cookies";
-//
-// All "debug mode" logging is compiled away to nothing for non-debug mode
-// compiles.  LOG_IF and development flags also work well together
-// because the code can be compiled away sometimes.
-//
-// We also have
-//
-//   LOG_ASSERT(assertion);
-//   DLOG_ASSERT(assertion);
-//
-// which is syntactic sugar for {,D}LOG_IF(FATAL, assert fails) << assertion;
-//
-// There are "verbose level" logging macros.  They look like
-//
-//   VLOG(1) << "I'm printed when you run the program with --v=1 or more";
-//   VLOG(2) << "I'm printed when you run the program with --v=2 or more";
-//
-// These always log at the INFO log level (when they log at all).
-// The verbose logging can also be turned on module-by-module.  For instance,
-//    --vmodule=profile=2,icon_loader=1,browser_*=3,*/chromeos/*=4 --v=0
-// will cause:
-//   a. VLOG(2) and lower messages to be printed from profile.{h,cc}
-//   b. VLOG(1) and lower messages to be printed from icon_loader.{h,cc}
-//   c. VLOG(3) and lower messages to be printed from files prefixed with
-//      "browser"
-//   d. VLOG(4) and lower messages to be printed from files under a
-//     "chromeos" directory.
-//   e. VLOG(0) and lower messages to be printed from elsewhere
-//
-// The wildcarding functionality shown by (c) supports both '*' (match
-// 0 or more characters) and '?' (match any single character)
-// wildcards.  Any pattern containing a forward or backward slash will
-// be tested against the whole pathname and not just the module.
-// E.g., "*/foo/bar/*=2" would change the logging level for all code
-// in source files under a "foo/bar" directory.
-//
-// There's also VLOG_IS_ON(n) "verbose level" condition macro. To be used as
-//
-//   if (VLOG_IS_ON(2)) {
-//     // do some logging preparation and logging
-//     // that can't be accomplished with just VLOG(2) << ...;
-//   }
-//
-// There is also a VLOG_IF "verbose level" condition macro for sample
-// cases, when some extra computation and preparation for logs is not
-// needed.
-//
-//   VLOG_IF(1, (size > 1024))
-//      << "I'm printed when size is more than 1024 and when you run the "
-//         "program with --v=1 or more";
-//
-// We also override the standard 'assert' to use 'DLOG_ASSERT'.
-//
-// Lastly, there is:
-//
-//   PLOG(ERROR) << "Couldn't do foo";
-//   DPLOG(ERROR) << "Couldn't do foo";
-//   PLOG_IF(ERROR, cond) << "Couldn't do foo";
-//   DPLOG_IF(ERROR, cond) << "Couldn't do foo";
-//   PCHECK(condition) << "Couldn't do foo";
-//   DPCHECK(condition) << "Couldn't do foo";
-//
-// which append the last system error to the message in string form (taken from
-// GetLastError() on Windows and errno on POSIX).
-//
-// The supported severity levels for macros that allow you to specify one
-// are (in increasing order of severity) INFO, WARNING, ERROR, and FATAL.
-//
-// Very important: logging a message at the FATAL severity level causes
-// the program to terminate (after the message is logged).

-// Macro with the boilerplate that makes a type move-only in C++03.
-//
-// USAGE
-//
-// This macro should be used instead of DISALLOW_COPY_AND_ASSIGN to create
-// a "move-only" type.  Unlike DISALLOW_COPY_AND_ASSIGN, this macro should be
-// the first line in a class declaration.
-//
-// A class using this macro must call .Pass() (or somehow be an r-value already)
-// before it can be:
-//
-//   * Passed as a function argument
-//   * Used as the right-hand side of an assignment
-//   * Returned from a function
-//
-// Each class will still need to define their own "move constructor" and "move
-// operator=" to make this useful.  Here's an example of the macro, the move
-// constructor, and the move operator= from the scoped_ptr class:
-//
-//  template <typename T>
-//  class scoped_ptr {
-//     MOVE_ONLY_TYPE_FOR_CPP_03(scoped_ptr, RValue)
-//   public:
-//    scoped_ptr(RValue& other) : ptr_(other.release()) { }
-//    scoped_ptr& operator=(RValue& other) {
-//      swap(other);
-//      return *this;
-//    }
-//  };
-//
-// Note that the constructor must NOT be marked explicit.
-//
-// For consistency, the second parameter to the macro should always be RValue
-// unless you have a strong reason to do otherwise.  It is only exposed as a
-// macro parameter so that the move constructor and move operator= don't look
-// like they're using a phantom type.
-//
-//
-// HOW THIS WORKS
-//
-// For a thorough explanation of this technique, see:
-//
-//   http://en.wikibooks.org/wiki/More_C%2B%2B_Idioms/Move_Constructor
-//
-// The summary is that we take advantage of 2 properties:
-//
-//   1) non-const references will not bind to r-values.
-//   2) C++ can apply one user-defined conversion when initializing a
-//      variable.
-//
-// The first lets us disable the copy constructor and assignment operator
-// by declaring private version of them with a non-const reference parameter.
-//
-// For l-values, direct initialization still fails like in
-// DISALLOW_COPY_AND_ASSIGN because the copy constructor and assignment
-// operators are private.
-//
-// For r-values, the situation is different. The copy constructor and
-// assignment operator are not viable due to (1), so we are trying to call
-// a non-existent constructor and non-existing operator= rather than a private
-// one.  Since we have not committed an error quite yet, we can provide an
-// alternate conversion sequence and a constructor.  We add
-//
-//   * a private struct named "RValue"
-//   * a user-defined conversion "operator RValue()"
-//   * a "move constructor" and "move operator=" that take the RValue& as
-//     their sole parameter.
-//
-// Only r-values will trigger this sequence and execute our "move constructor"
-// or "move operator=."  L-values will match the private copy constructor and
-// operator= first giving a "private in this context" error.  This combination
-// gives us a move-only type.
-//
-// For signaling a destructive transfer of data from an l-value, we provide a
-// method named Pass() which creates an r-value for the current instance
-// triggering the move constructor or move operator=.
-//
-// Other ways to get r-values is to use the result of an expression like a
-// function call.
-//
-// Here's an example with comments explaining what gets triggered where:
-//
-//    class Foo {
-//      MOVE_ONLY_TYPE_FOR_CPP_03(Foo, RValue);
-//
-//     public:
-//       ... API ...
-//       Foo(RValue other);           // Move constructor.
-//       Foo& operator=(RValue rhs);  // Move operator=
-//    };
-//
-//    Foo MakeFoo();  // Function that returns a Foo.
-//
-//    Foo f;
-//    Foo f_copy(f);  // ERROR: Foo(Foo&) is private in this context.
-//    Foo f_assign;
-//    f_assign = f;   // ERROR: operator=(Foo&) is private in this context.
-//
-//
-//    Foo f(MakeFoo());      // R-value so alternate conversion executed.
-//    Foo f_copy(f.Pass());  // R-value so alternate conversion executed.
-//    f = f_copy.Pass();     // R-value so alternate conversion executed.
-//
-//
-// IMPLEMENTATION SUBTLETIES WITH RValue
-//
-// The RValue struct is just a container for a pointer back to the original
-// object. It should only ever be created as a temporary, and no external
-// class should ever declare it or use it in a parameter.
-//
-// It is tempting to want to use the RValue type in function parameters, but
-// excluding the limited usage here for the move constructor and move
-// operator=, doing so would mean that the function could take both r-values
-// and l-values equially which is unexpected.  See COMPARED To Boost.Move for
-// more details.
-//
-// An alternate, and incorrect, implementation of the RValue class used by
-// Boost.Move makes RValue a fieldless child of the move-only type. RValue&
-// is then used in place of RValue in the various operators.  The RValue& is
-// "created" by doing *reinterpret_cast<RValue*>(this).  This has the appeal
-// of never creating a temporary RValue struct even with optimizations
-// disabled.  Also, by virtue of inheritance you can treat the RValue
-// reference as if it were the move-only type itself.  Unfortunately,
-// using the result of this reinterpret_cast<> is actually undefined behavior
-// due to C++98 5.2.10.7. In certain compilers (e.g., NaCl) the optimizer
-// will generate non-working code.
-//
-// In optimized builds, both implementations generate the same assembly so we
-// choose the one that adheres to the standard.
-//
-//
-// WHY HAVE typedef void MoveOnlyTypeForCPP03
-//
-// Callback<>/Bind() needs to understand movable-but-not-copyable semantics
-// to call .Pass() appropriately when it is expected to transfer the value.
-// The cryptic typedef MoveOnlyTypeForCPP03 is added to make this check
-// easy and automatic in helper templates for Callback<>/Bind().
-// See IsMoveOnlyType template and its usage in base/callback_internal.h
-// for more details.
-//
-//
-// COMPARED TO C++11
-//
-// In C++11, you would implement this functionality using an r-value reference
-// and our .Pass() method would be replaced with a call to std::move().
-//
-// This emulation also has a deficiency where it uses up the single
-// user-defined conversion allowed by C++ during initialization.  This can
-// cause problems in some API edge cases.  For instance, in scoped_ptr, it is
-// impossible to make a function "void Foo(scoped_ptr<Parent> p)" accept a
-// value of type scoped_ptr<Child> even if you add a constructor to
-// scoped_ptr<> that would make it look like it should work.  C++11 does not
-// have this deficiency.
-//
-//
-// COMPARED TO Boost.Move
-//
-// Our implementation similar to Boost.Move, but we keep the RValue struct
-// private to the move-only type, and we don't use the reinterpret_cast<> hack.
-//
-// In Boost.Move, RValue is the boost::rv<> template.  This type can be used
-// when writing APIs like:
-//
-//   void MyFunc(boost::rv<Foo>& f)
-//
-// that can take advantage of rv<> to avoid extra copies of a type.  However you
-// would still be able to call this version of MyFunc with an l-value:
-//
-//   Foo f;
-//   MyFunc(f);  // Uh oh, we probably just destroyed |f| w/o calling Pass().
-//
-// unless someone is very careful to also declare a parallel override like:
-//
-//   void MyFunc(const Foo& f)
-//
-// that would catch the l-values first.  This was declared unsafe in C++11 and
-// a C++11 compiler will explicitly fail MyFunc(f).  Unfortunately, we cannot
-// ensure this in C++03.
-//
-// Since we have no need for writing such APIs yet, our implementation keeps
-// RValue private and uses a .Pass() method to do the conversion instead of
-// trying to write a version of "std::move()." Writing an API like std::move()
-// would require the RValue struct to be public.
-//
-//
-// CAVEATS
-//
-// If you include a move-only type as a field inside a class that does not
-// explicitly declare a copy constructor, the containing class's implicit
-// copy constructor will change from Containing(const Containing&) to
-// Containing(Containing&).  This can cause some unexpected errors.
-//
-//   http://llvm.org/bugs/show_bug.cgi?id=11528
-//

-// A smart pointer class for reference counted objects.  Use this class instead
-// of calling AddRef and Release manually on a reference counted object to
-// avoid common memory leaks caused by forgetting to Release an object
-// reference.  Sample usage:
-//
-//   class MyFoo : public RefCounted<MyFoo> {
-//    ...
-//   };
-//
-//   void some_function() {
-//     scoped_refptr<MyFoo> foo = new MyFoo();
-//     foo->Method(param);
-//     // |foo| is released when this function returns
-//   }
-//
-//   void some_other_function() {
-//     scoped_refptr<MyFoo> foo = new MyFoo();
-//     ...
-//     foo = NULL;  // explicitly releases |foo|
-//     ...
-//     if (foo)
-//       foo->Method(param);
-//   }
-//
-// The above examples show how scoped_refptr<T> acts like a pointer to T.
-// Given two scoped_refptr<T> classes, it is also possible to exchange
-// references between the two objects, like so:
-//
-//   {
-//     scoped_refptr<MyFoo> a = new MyFoo();
-//     scoped_refptr<MyFoo> b;
-//
-//     b.swap(a);
-//     // now, |b| references the MyFoo object, and |a| references NULL.
-//   }
-//
-// To make both |a| and |b| in the above example reference the same MyFoo
-// object, simply use the assignment operator:
-//
-//   {
-//     scoped_refptr<MyFoo> a = new MyFoo();
-//     scoped_refptr<MyFoo> b;
-//
-//     b = a;
-//     // now, |a| and |b| each own a reference to the same MyFoo object.

-// Scopers help you manage ownership of a pointer, helping you easily manage a
-// pointer within a scope, and automatically destroying the pointer at the end
-// of a scope.  There are two main classes you will use, which correspond to the
-// operators new/delete and new[]/delete[].
-//
-// Example usage (scoped_ptr<T>):
-//   {
-//     scoped_ptr<Foo> foo(new Foo("wee"));
-//   }  // foo goes out of scope, releasing the pointer with it.
-//
-//   {
-//     scoped_ptr<Foo> foo;          // No pointer managed.
-//     foo.reset(new Foo("wee"));    // Now a pointer is managed.
-//     foo.reset(new Foo("wee2"));   // Foo("wee") was destroyed.
-//     foo.reset(new Foo("wee3"));   // Foo("wee2") was destroyed.
-//     foo->Method();                // Foo::Method() called.
-//     foo.get()->Method();          // Foo::Method() called.
-//     SomeFunc(foo.release());      // SomeFunc takes ownership, foo no longer
-//                                   // manages a pointer.
-//     foo.reset(new Foo("wee4"));   // foo manages a pointer again.
-//     foo.reset();                  // Foo("wee4") destroyed, foo no longer
-//                                   // manages a pointer.
-//   }  // foo wasn't managing a pointer, so nothing was destroyed.
-//
-// Example usage (scoped_ptr<T[]>):
-//   {
-//     scoped_ptr<Foo[]> foo(new Foo[100]);
-//     foo.get()->Method();  // Foo::Method on the 0th element.
-//     foo[10].Method();     // Foo::Method on the 10th element.
-//   }
-//
-// These scopers also implement part of the functionality of C++11 unique_ptr
-// in that they are "movable but not copyable."  You can use the scopers in
-// the parameter and return types of functions to signify ownership transfer
-// in to and out of a function.  When calling a function that has a scoper
-// as the argument type, it must be called with the result of an analogous
-// scoper's Pass() function or another function that generates a temporary;
-// passing by copy will NOT work.  Here is an example using scoped_ptr:
-//
-//   void TakesOwnership(scoped_ptr<Foo> arg) {
-//     // Do something with arg
-//   }
-//   scoped_ptr<Foo> CreateFoo() {
-//     // No need for calling Pass() because we are constructing a temporary
-//     // for the return value.
-//     return scoped_ptr<Foo>(new Foo("new"));
-//   }
-//   scoped_ptr<Foo> PassThru(scoped_ptr<Foo> arg) {
-//     return arg.Pass();
-//   }
-//
-//   {
-//     scoped_ptr<Foo> ptr(new Foo("yay"));  // ptr manages Foo("yay").
-//     TakesOwnership(ptr.Pass());           // ptr no longer owns Foo("yay").
-//     scoped_ptr<Foo> ptr2 = CreateFoo();   // ptr2 owns the return Foo.
-//     scoped_ptr<Foo> ptr3 =                // ptr3 now owns what was in ptr2.
-//         PassThru(ptr2.Pass());            // ptr2 is correspondingly NULL.
-//   }
-//
-// Notice that if you do not call Pass() when returning from PassThru(), or
-// when invoking TakesOwnership(), the code will not compile because scopers
-// are not copyable; they only implement move semantics which require calling
-// the Pass() function to signify a destructive transfer of state. CreateFoo()
-// is different though because we are constructing a temporary on the return
-// line and thus can avoid needing to call Pass().
-//
-// Pass() properly handles upcast in initialization, i.e. you can use a
-// scoped_ptr<Child> to initialize a scoped_ptr<Parent>:
-//
-//   scoped_ptr<Foo> foo(new Foo());
-//   scoped_ptr<FooParent> parent(foo.Pass());
-//
-// PassAs<>() should be used to upcast return value in return statement:
-//
-//   scoped_ptr<Foo> CreateFoo() {
-//     scoped_ptr<FooChild> result(new FooChild());
-//     return result.PassAs<Foo>();
-//   }
-//
-// Note that PassAs<>() is implemented only for scoped_ptr<T>, but not for
-// scoped_ptr<T[]>. This is because casting array pointers may not be safe.

+///    private:
+///     friend class RefCounted<MyFoo>;  // Allow destruction by RefCounted<>.

+///     ...
+///     if (foo)
+///       foo->Method(param);
+///   }
+/// </pre>
+///
+/// The above examples show how scoped_refptr<T> acts like a pointer to T.
+/// Given two scoped_refptr<T> classes, it is also possible to exchange
+/// references between the two objects, like so:
+///
+/// <pre>
+///   {
+///     scoped_refptr<MyFoo> a = MakeRefCounted<MyFoo>();
+///     scoped_refptr<MyFoo> b;
+///
+///     b.swap(a);
+///     // now, |b| references the MyFoo object, and |a| references nullptr.
+///   }
+/// </pre>
+///
+/// To make both |a| and |b| in the above example reference the same MyFoo
+/// object, simply use the assignment operator:
+///
+/// <pre>
+///   {
+///     scoped_refptr<MyFoo> a = MakeRefCounted<MyFoo>();
+///     scoped_refptr<MyFoo> b;
+///
+///     b = a;
+///     // now, |a| and |b| each own a reference to the same MyFoo object.
+///   }
+/// </pre>
+///
+/// Also see Chromium's ownership and calling conventions:
+/// https://chromium.googlesource.com/chromium/src/+/lkgr/styleguide/c++/c++.md#object-ownership-and-calling-conventions
+/// Specifically:
+///   If the function (at least sometimes) takes a ref on a refcounted object,
+///   declare the param as scoped_refptr<T>. The caller can decide whether it
+///   wishes to transfer ownership (by calling std::move(t) when passing t) or
+///   retain its ref (by simply passing t directly).
+///   In other words, use scoped_refptr like you would a std::unique_ptr except
+///   in the odd case where it's required to hold on to a ref while handing one
+///   to another component (if a component merely needs to use t on the stack
+///   without keeping a ref: pass t as a raw T*).

-// WHAT:
-// A version of std::basic_string that provides 2-byte characters even when
-// wchar_t is not implemented as a 2-byte type. You can access this class as
-// string16. We also define char16, which string16 is based upon.
-//
-// WHY:
-// On Windows, wchar_t is 2 bytes, and it can conveniently handle UTF-16/UCS-2
-// data. Plenty of existing code operates on strings encoded as UTF-16.
-//
-// On many other platforms, sizeof(wchar_t) is 4 bytes by default. We can make
-// it 2 bytes by using the GCC flag -fshort-wchar. But then std::wstring fails
-// at run time, because it calls some functions (like wcslen) that come from
-// the system's native C library -- which was built with a 4-byte wchar_t!
-// It's wasteful to use 4-byte wchar_t strings to carry UTF-16 data, and it's
-// entirely improper on those systems where the encoding of wchar_t is defined
-// as UTF-32.
-//
-// Here, we define string16, which is similar to std::wstring but replaces all
-// libc functions with custom, 2-byte-char compatible routines. It is capable
-// of carrying UTF-16-encoded data.

-// std::basic_string<> in GNU libstdc++ contains a static data member,
-// _S_empty_rep_storage, to represent empty strings.  When an operation such
-// as assignment or destruction is performed on a string, causing its existing
-// data member to be invalidated, it must not be freed if this static data
-// member is being used.  Otherwise, it counts as an attempt to free static
-// (and not allocated) data, which is a memory error.
-//
-// Generally, due to C++ template magic, _S_empty_rep_storage will be marked
-// as a coalesced symbol, meaning that the linker will combine multiple
-// instances into a single one when generating output.
-//
-// If a string class is used by multiple shared libraries, a problem occurs.
-// Each library will get its own copy of _S_empty_rep_storage.  When strings
-// are passed across a library boundary for alteration or destruction, memory
-// errors will result.  GNU libstdc++ contains a configuration option,
-// --enable-fully-dynamic-string (_GLIBCXX_FULLY_DYNAMIC_STRING), which
-// disables the static data member optimization, but it's a good optimization
-// and non-STL code is generally at the mercy of the system's STL
-// configuration.  Fully-dynamic strings are not the default for GNU libstdc++
-// libstdc++ itself or for the libstdc++ installations on the systems we care
-// about, such as Mac OS X and relevant flavors of Linux.
-//
-// See also http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24196 .
-//
-// To avoid problems, string classes need to be explicitly instantiated only
-// once, in exactly one library.  All other string users see it via an "extern"
-// declaration.  This is precisely how GNU libstdc++ handles
-// std::basic_string<char> (string) and std::basic_string<wchar_t> (wstring).
-//
-// This also works around a Mac OS X linker bug in ld64-85.2.1 (Xcode 3.1.2),
-// in which the linker does not fully coalesce symbols when dead code
-// stripping is enabled.  This bug causes the memory errors described above
-// to occur even when a std::basic_string<> does not cross shared library
-// boundaries, such as in statically-linked executables.

+//   in libc++'s commit r239653 this is fixed by libc++ checking for gcc 5.1.
+// - In both of the above cases we are using the gcc compiler. When defining
+//   this ourselves on compiler intrinsics, the __is_trivially_copyable()
+//   intrinsic is not available on gcc before version 5.1 (see the discussion in
+//   https://llvm.org/bugs/show_bug.cgi?id=27538#c1 again), so we must check for
+//   that version.
+// - When __is_trivially_copyable() is not available because we are on gcc older
+//   than 5.1, we need to fall back to something, so we use __has_trivial_copy()
+//   instead based on what was done one-off in bit_cast() previously.

-// Trace events are for tracking application performance and resource usage.
-// Macros are provided to track:
-//    Begin and end of function calls
-//    Counters
-//
-// Events are issued against categories. Whereas LOG's categories are statically
-// defined, TRACE categories are created implicitly with a string. For example:
-//   TRACE_EVENT_INSTANT0("MY_SUBSYSTEM", "SomeImportantEvent")
-//
-// Events can be INSTANT, or can be pairs of BEGIN and END in the same scope:
-//   TRACE_EVENT_BEGIN0("MY_SUBSYSTEM", "SomethingCostly")
-//   doSomethingCostly()
-//   TRACE_EVENT_END0("MY_SUBSYSTEM", "SomethingCostly")
-// Note: Our tools can't always determine the correct BEGIN/END pairs unless
-// these are used in the same scope. Use ASYNC_BEGIN/ASYNC_END macros if you
-// need them to be in separate scopes.
-//
-// A common use case is to trace entire function scopes. This issues a trace
-// BEGIN and END automatically:
-//   void doSomethingCostly() {
-//     TRACE_EVENT0("MY_SUBSYSTEM", "doSomethingCostly");
-//     ...
-//   }
-//
-// Additional parameters can be associated with an event:
-//   void doSomethingCostly2(int howMuch) {
-//     TRACE_EVENT1("MY_SUBSYSTEM", "doSomethingCostly",
-//         "howMuch", howMuch);
-//     ...
-//   }
-//
-// The trace system will automatically add to this information the current
-// process id, thread id, and a timestamp in microseconds.
-//
-// To trace an asynchronous procedure such as an IPC send/receive, use
-// ASYNC_BEGIN and ASYNC_END:
-//   [single threaded sender code]
-//     static int send_count = 0;
-//     ++send_count;
-//     TRACE_EVENT_ASYNC_BEGIN0("ipc", "message", send_count);
-//     Send(new MyMessage(send_count));
-//   [receive code]
-//     void OnMyMessage(send_count) {
-//       TRACE_EVENT_ASYNC_END0("ipc", "message", send_count);
-//     }
-// The third parameter is a unique ID to match ASYNC_BEGIN/ASYNC_END pairs.
-// ASYNC_BEGIN and ASYNC_END can occur on any thread of any traced process.
-// Pointers can be used for the ID parameter, and they will be mangled
-// internally so that the same pointer on two different processes will not
-// match. For example:
-//   class MyTracedClass {
-//    public:
-//     MyTracedClass() {
-//       TRACE_EVENT_ASYNC_BEGIN0("category", "MyTracedClass", this);
-//     }
-//     ~MyTracedClass() {
-//       TRACE_EVENT_ASYNC_END0("category", "MyTracedClass", this);
-//     }
-//   }
-//
-// The trace event also supports counters, which is a way to track a quantity
-// as it varies over time. Counters are created with the following macro:
-//   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter", g_myCounterValue);
-//
-// Counters are process-specific. The macro itself can be issued from any
-// thread, however.
-//
-// Sometimes, you want to track two counters at once. You can do this with two
-// counter macros:
-//   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter0", g_myCounterValue[0]);
-//   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter1", g_myCounterValue[1]);
-// Or you can do it with a combined macro:
-//   TRACE_COUNTER2("MY_SUBSYSTEM", "myCounter",
-//       "bytesPinned", g_myCounterValue[0],
-//       "bytesAllocated", g_myCounterValue[1]);
-// This indicates to the tracing UI that these counters should be displayed
-// in a single graph, as a summed area chart.
-//
-// Since counters are in a global namespace, you may want to disembiguate with a
-// unique ID, by using the TRACE_COUNTER_ID* variations.
-//
-// By default, trace collection is compiled in, but turned off at runtime.
-// Collecting trace data is the responsibility of the embedding application. In
-// CEF's case, calling BeginTracing will turn on tracing on all active
-// processes.
-//
-//
-// Memory scoping note:
-// Tracing copies the pointers, not the string content, of the strings passed
-// in for category, name, and arg_names.  Thus, the following code will cause
-// problems:
-//     char* str = strdup("impprtantName");
-//     TRACE_EVENT_INSTANT0("SUBSYSTEM", str);  // BAD!
-//     free(str);                   // Trace system now has dangling pointer
-//
-// To avoid this issue with the |name| and |arg_name| parameters, use the
-// TRACE_EVENT_COPY_XXX overloads of the macros at additional runtime
-// overhead.
-// Notes: The category must always be in a long-lived char* (i.e. static const).
-//        The |arg_values|, when used, are always deep copied with the _COPY
-//        macros.
-//
-//
-// Thread Safety:

+/// Trace events are for tracking application performance and resource usage.
+/// Macros are provided to track:
+///    Begin and end of function calls
+///    Counters
+///
+/// Events are issued against categories. Whereas LOG's categories are
+/// statically defined, TRACE categories are created implicitly with a string.
+/// For example: <pre>
+///   TRACE_EVENT_INSTANT0("MY_SUBSYSTEM", "SomeImportantEvent")
+/// </pre>
+///
+/// Events can be INSTANT, or can be pairs of BEGIN and END in the same scope:
+/// <pre>
+///   TRACE_EVENT_BEGIN0("MY_SUBSYSTEM", "SomethingCostly")
+///   doSomethingCostly()
+///   TRACE_EVENT_END0("MY_SUBSYSTEM", "SomethingCostly")
+/// </pre>
+/// Note: Our tools can't always determine the correct BEGIN/END pairs unless
+/// these are used in the same scope. Use ASYNC_BEGIN/ASYNC_END macros if you
+/// need them to be in separate scopes.
+///
+/// A common use case is to trace entire function scopes. This issues a trace
+/// BEGIN and END automatically:
+/// <pre>
+///   void doSomethingCostly() {
+///     TRACE_EVENT0("MY_SUBSYSTEM", "doSomethingCostly");
+///     ...
+///   }
+/// </pre>
+///
+/// Additional parameters can be associated with an event:
+/// <pre>
+///   void doSomethingCostly2(int howMuch) {
+///     TRACE_EVENT1("MY_SUBSYSTEM", "doSomethingCostly",
+///         "howMuch", howMuch);
+///     ...
+///   }
+/// </pre>
+///
+/// The trace system will automatically add to this information the current
+/// process id, thread id, and a timestamp in microseconds.
+///
+/// To trace an asynchronous procedure such as an IPC send/receive, use
+/// ASYNC_BEGIN and ASYNC_END:
+/// <pre>
+///   [single threaded sender code]
+///     static int send_count = 0;
+///     ++send_count;
+///     TRACE_EVENT_ASYNC_BEGIN0("ipc", "message", send_count);
+///     Send(new MyMessage(send_count));
+///   [receive code]
+///     void OnMyMessage(send_count) {
+///       TRACE_EVENT_ASYNC_END0("ipc", "message", send_count);
+///     }
+/// </pre>
+/// The third parameter is a unique ID to match ASYNC_BEGIN/ASYNC_END pairs.
+/// ASYNC_BEGIN and ASYNC_END can occur on any thread of any traced process.
+/// Pointers can be used for the ID parameter, and they will be mangled
+/// internally so that the same pointer on two different processes will not
+/// match. For example:
+/// <pre>
+///   class MyTracedClass {
+///    public:
+///     MyTracedClass() {
+///       TRACE_EVENT_ASYNC_BEGIN0("category", "MyTracedClass", this);
+///     }
+///     ~MyTracedClass() {
+///       TRACE_EVENT_ASYNC_END0("category", "MyTracedClass", this);
+///     }
+///   }
+/// </pre>
+///
+/// The trace event also supports counters, which is a way to track a quantity
+/// as it varies over time. Counters are created with the following macro:
+/// <pre>
+///   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter", g_myCounterValue);
+/// </pre>
+///
+/// Counters are process-specific. The macro itself can be issued from any
+/// thread, however.
+///
+/// Sometimes, you want to track two counters at once. You can do this with two
+/// counter macros:
+/// <pre>
+///   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter0", g_myCounterValue[0]);
+///   TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter1", g_myCounterValue[1]);
+/// </pre>
+/// Or you can do it with a combined macro:
+/// <pre>
+///   TRACE_COUNTER2("MY_SUBSYSTEM", "myCounter",
+///       "bytesPinned", g_myCounterValue[0],
+///       "bytesAllocated", g_myCounterValue[1]);
+/// </pre>
+/// This indicates to the tracing UI that these counters should be displayed
+/// in a single graph, as a summed area chart.
+///
+/// Since counters are in a global namespace, you may want to disembiguate with
+/// a unique ID, by using the TRACE_COUNTER_ID* variations.
+///
+/// By default, trace collection is compiled in, but turned off at runtime.
+/// Collecting trace data is the responsibility of the embedding application. In
+/// CEF's case, calling BeginTracing will turn on tracing on all active
+/// processes.
+///
+///
+/// Memory scoping note:
+/// Tracing copies the pointers, not the string content, of the strings passed
+/// in for category, name, and arg_names.  Thus, the following code will cause
+/// problems:
+/// <pre>
+///     char* str = strdup("impprtantName");
+///     TRACE_EVENT_INSTANT0("SUBSYSTEM", str);  // BAD!
+///     free(str);                   // Trace system now has dangling pointer
+/// </pre>
+///
+/// To avoid this issue with the |name| and |arg_name| parameters, use the
+/// TRACE_EVENT_COPY_XXX overloads of the macros at additional runtime
+/// overhead.
+///
+/// Notes: The category must always be in a long-lived char* (i.e. static
+///        const). The |arg_values|, when used, are always deep copied with
+///        the _COPY macros.
+///
+///
+/// Thread Safety:
+/// All macros are thread safe and can be used from any process.

-//
-// If all WeakPtr objects are destroyed or invalidated then the factory is

+/// Weak pointers may be passed safely between threads, but must always be
+/// dereferenced and invalidated on the same ThreaddTaskRunner otherwise
+/// checking the pointer would be racey.
+///
+/// To ensure correct use, the first time a WeakPtr issued by a WeakPtrFactory
+/// is dereferenced, the factory and its WeakPtrs become bound to the calling
+/// thread or current ThreaddWorkerPool token, and cannot be dereferenced or
+/// invalidated on any other task runner. Bound WeakPtrs can still be handed
+/// off to other task runners, e.g. to use to post tasks back to object on the
+/// bound thread.
+///
+/// If all WeakPtr objects are destroyed or invalidated then the factory is
+/// unbound from the ThreadedTaskRunner/Thread. The WeakPtrFactory may then be
+/// destroyed, or new WeakPtr objects may be used, from a different thread.
+///
+/// Thus, at least one WeakPtr object must exist and have been dereferenced on
+/// the correct thread to enforce that other WeakPtr objects will enforce they
+/// are used on the desired thread.

-// * ARMv5 didn't support SMP, there is no memory barrier instruction at

-//
-// * Some ARMv6 CPUs support SMP. A full memory barrier can be produced by
-//   writing a random value to a very specific coprocessor register.
-//
-// * On ARMv7, the "dmb" instruction is used to perform a full memory
-//   barrier (though writing to the co-processor will still work).
-//   However, on single core devices (e.g. Nexus One, or Nexus S),
-//   this instruction will take up to 200 ns, which is huge, even though
-//   it's completely un-needed on these devices.
-//
-// * There is no easy way to determine at runtime if the device is
-//   single or multi-core. However, the kernel provides a useful helper
-//   function at a fixed memory address (0xffff0fa0), which will always
-//   perform a memory barrier in the most efficient way. I.e. on single
-//   core devices, this is an empty function that exits immediately.
-//   On multi-core devices, it implements a full memory barrier.
-//
-// * This source could be compiled to ARMv5 machine code that runs on a
-//   multi-core ARMv6 or ARMv7 device. In this case, memory barriers
-//   are needed for correct execution. Always call the kernel helper, even

+/// Implement this structure to handle events related to cef_frame_t life span.

+///
+/// (1) During initial cef_browser_host_t creation and navigation of the main
+/// frame: - cef_frame_handler_t::OnFrameCreated => The initial main frame
+/// object has been
+///   created. Any commands will be queued until the frame is attached.
+/// - cef_frame_handler_t::OnMainFrameChanged => The initial main frame object
+/// has
+///   been assigned to the browser.
+/// - cef_life_span_handler_t::OnAfterCreated => The browser is now valid and
+/// can be
+///   used.
+/// - cef_frame_handler_t::OnFrameAttached => The initial main frame object is
+/// now
+///   connected to its peer in the renderer process. Commands can be routed.
+///
+/// (2) During further cef_browser_host_t navigation/loading of the main frame
+///     and/or sub-frames:
+/// - cef_frame_handler_t::OnFrameCreated => A new main frame or sub-frame
+/// object
+///   has been created. Any commands will be queued until the frame is attached.
+/// - cef_frame_handler_t::OnFrameAttached => A new main frame or sub-frame
+/// object
+///   is now connected to its peer in the renderer process. Commands can be
+///   routed.
+/// - cef_frame_handler_t::OnFrameDetached => An existing main frame or sub-
+/// frame
+///   object has lost its connection to the renderer process. If multiple
+///   objects are detached at the same time then notifications will be sent for
+///   any sub-frame objects before the main frame object. Commands can no longer
+///   be routed and will be discarded.
+/// - cef_frame_handler_t::OnMainFrameChanged => A new main frame object has
+/// been
+///   assigned to the browser. This will only occur with cross-origin navigation
+///   or re-navigation after renderer process termination (due to crashes, etc).
+///
+/// (3) During final cef_browser_host_t destruction of the main frame: -
+/// cef_frame_handler_t::OnFrameDetached => Any sub-frame objects have lost
+/// their
+///   connection to the renderer process. Commands can no longer be routed and
+///   will be discarded.
+/// - cef_life_span_handler_t::OnBeforeClose => The browser has been destroyed.
+/// - cef_frame_handler_t::OnFrameDetached => The main frame object have lost
+/// its
+///   connection to the renderer process. Notifications will be sent for any
+///   sub-frame objects before the main frame object. Commands can no longer be
+///   routed and will be discarded.
+/// - cef_frame_handler_t::OnMainFrameChanged => The final main frame object has
+///   been removed from the browser.
+///
+/// Cross-origin navigation and/or loading receives special handling.
+///
+/// When the main frame navigates to a different origin the OnMainFrameChanged
+/// callback (2) will be executed with the old and new main frame objects.
+///
+/// When a new sub-frame is loaded in, or an existing sub-frame is navigated to,
+/// a different origin from the parent frame, a temporary sub-frame object will
+/// first be created in the parent's renderer process. That temporary sub-frame
+/// will then be discarded after the real cross-origin sub-frame is created in
+/// the new/target renderer process. The client will receive cross-origin
+/// navigation callbacks (2) for the transition from the temporary sub-frame to
+/// the real sub-frame. The temporary sub-frame will not recieve or execute
+/// commands during this transitional period (any sent commands will be
+/// discarded).
+///
+/// When a new popup browser is created in a different origin from the parent
+/// browser, a temporary main frame object for the popup will first be created
+/// in the parent's renderer process. That temporary main frame will then be
+/// discarded after the real cross-origin main frame is created in the
+/// new/target renderer process. The client will recieve creation and initial
+/// navigation callbacks (1) for the temporary main frame, followed by cross-
+/// origin navigation callbacks (2) for the transition from the temporary main
