Moved common cross-project functionality out from SkTraceEvent.h into SkTraceEventCommon.h
Traditionally, SkTraceEvent.h was manually kept in sync with base/trace_event/trace_event.h, with project-specific parts intermixed, and tended to drift out of sync a lot (mainly in Blink, less so in Skia). The SkTraceEventCommon.h now has only the cross-project parts, and can be copy-pasted verbatim between projects (it's an identical copy of base/trace_event/trace_event_common.h), meaning SkTraceEvent.h shouldn't go out of sync as it has before.

// 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.
|
||||
|
||||
// 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"));
|
||||
//
|
||||
//
|
||||
// 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.
|
||||
// This header file defines implementation details of how the trace macros in
|
||||
// SkTraceEventCommon.h collect and store trace events. Anything not
|
||||
// implementation-specific should go in SkTraceEventCommon.h instead of here.
