// 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:

// All macros are thread safe and can be used from any process.
