-// This header file defines the set of trace_event macros without specifying
-// how the events actually get collected and stored. If you need to expose trace
-// events to some other universe, you can copy-and-paste this file as well as
-// trace_event.h, modifying the macros contained there as necessary for the
-// target platform. The end result is that multiple libraries can funnel events
-// through to a shared trace event collector.
-
-// IMPORTANT: To avoid conflicts, if you need to modify this file for a library,
-// land your change in base/ first, and then copy-and-paste it.
-
-// 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",
-// TRACE_EVENT_SCOPE_THREAD)
-//
-// It is often the case that one trace may belong in multiple categories at the
-// same time. The first argument to the trace can be a comma-separated list of
-// categories, forming a category group, like:
-//
-// TRACE_EVENT_INSTANT0("input,views", "OnMouseOver", TRACE_EVENT_SCOPE_THREAD)
-//
-// We can enable/disable tracing of OnMouseOver by enabling/disabling either
-// category.
-//
-// 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);
-// }
-// }
-//
-// 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 disambiguate 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 Chrome's case, navigating to about:tracing will turn on
-// tracing and display data collected across all active processes.
-//
-//
-// Memory scoping note:
-// Tracing copies the pointers, not the string content, of the strings passed
-// in for category_group, name, and arg_names. Thus, the following code will
-// cause problems:
-// char* str = strdup("importantName");
-// 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.
-//
-// When are string argument values copied:
-// const char* arg_values are only referenced by default:
-// TRACE_EVENT1("category", "name",
-// "arg1", "literal string is only referenced");
-// Use TRACE_STR_COPY to force copying of a const char*:
-// TRACE_EVENT1("category", "name",
-// "arg1", TRACE_STR_COPY("string will be copied"));
-// std::string arg_values are always copied:
-// TRACE_EVENT1("category", "name",
-// "arg1", std::string("string will be copied"));
-//
-//
-// Convertable notes:
-// Unlike base's trace framework, no convertable support in Blink because of
-// the way we estimate tracing memory overhead. All objects passed to the
-// tracing framework should be allocated by malloc to calculate overhead
-// correctly, while many Blink objects use PartitionAlloc/Oilpan. Convertable
-// is an interface to avoid unnecessary conversion but if we allow to use
-// PartitionAlloc/Oilpan backed objects, overhead estimation could be wrong.
-// For structured objects, you can use TracedValue.
-//
-// class MyData {
-// public:
-// MyData() {}
-// std::unique_ptr<TracedValue> toTracedValue() {
-// std::unique_ptr<TracedValue> tracedValue = TracedValue::create();
-// tracedValue->setInteger("foo", 1);
-// tracedValue->beginArray("bar");
-// tracedValue->pushInteger(2);
-// tracedValue->pushInteger(3);
-// tracedValue->endArray();
-// return tracedValue.release();
-// }
-// private:
-// ~MyData() override {}
-// };
-//
-// TRACE_EVENT1("foo", "bar", "data", myData.toTracedValue());
-//
-// The trace framework will take ownership.
-//
-//
-// Thread Safety:
-// A thread safe singleton and mutex are used for thread safety. Category
-// enabled flags are used to limit the performance impact when the system
-// is not enabled.
-//
-// TRACE_EVENT macros first cache a pointer to a category. The categories are
-// statically allocated and safe at all times, even after exit. Fetching a
-// category is protected by the TraceLog::lock_. Multiple threads initializing
-// the static variable is safe, as they will be serialized by the lock and
-// multiple calls will return the same pointer to the category.
-//
-// Then the category_group_enabled flag is checked. This is a unsigned char, and
-// not intended to be multithread safe. It optimizes access to AddTraceEvent
-// which is threadsafe internally via TraceLog::lock_. The enabled flag may
-// cause some threads to incorrectly call or skip calling AddTraceEvent near
-// the time of the system being enabled or disabled. This is acceptable as
-// we tolerate some data loss while the system is being enabled/disabled and
-// because AddTraceEvent is threadsafe internally and checks the enabled state
-// again under lock.
-//
-// Without the use of these static category pointers and enabled flags all
-// trace points would carry a significant performance cost of acquiring a lock
-// and resolving the category.
