If you need to expose trace +// event to some other universe, you can copy-and-paste this file, +// implement the TRACE_EVENT_API macros, and do any other necessary fixup for +// the target platform. The end result is that multiple libraries can funnel +// events through to a shared trace event collector. + +// 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 RTC_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); +// } +// } +// +// 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 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, 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. +// +// 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")); +// +// +// Thread Safety: +// Thread safety is provided by methods defined in event_tracer.h.
