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.
