| 5 | // This header file defines the set of trace_event macros without specifying |
| 6 | // how the events actually get collected and stored. If you need to expose trace |
| 7 | // events to some other universe, you can copy-and-paste this file as well as |
| 8 | // trace_event.h, modifying the macros contained there as necessary for the |
| 9 | // target platform. The end result is that multiple libraries can funnel events |
| 10 | // through to a shared trace event collector. |
| 11 | |
| 12 | // IMPORTANT: To avoid conflicts, if you need to modify this file for a library, |
| 13 | // land your change in base/ first, and then copy-and-paste it. |
| 14 | |
| 15 | // Trace events are for tracking application performance and resource usage. |
| 16 | // Macros are provided to track: |
| 17 | // Begin and end of function calls |
| 18 | // Counters |
| 19 | // |
| 20 | // Events are issued against categories. Whereas LOG's |
| 21 | // categories are statically defined, TRACE categories are created |
| 22 | // implicitly with a string. For example: |
| 23 | // TRACE_EVENT_INSTANT0("MY_SUBSYSTEM", "SomeImportantEvent", |
| 24 | // TRACE_EVENT_SCOPE_THREAD) |
| 25 | // |
| 26 | // It is often the case that one trace may belong in multiple categories at the |
| 27 | // same time. The first argument to the trace can be a comma-separated list of |
| 28 | // categories, forming a category group, like: |
| 29 | // |
| 30 | // TRACE_EVENT_INSTANT0("input,views", "OnMouseOver", TRACE_EVENT_SCOPE_THREAD) |
| 31 | // |
| 32 | // We can enable/disable tracing of OnMouseOver by enabling/disabling either |
| 33 | // category. |
| 34 | // |
| 35 | // Events can be INSTANT, or can be pairs of BEGIN and END in the same scope: |
| 36 | // TRACE_EVENT_BEGIN0("MY_SUBSYSTEM", "SomethingCostly") |
| 37 | // doSomethingCostly() |
| 38 | // TRACE_EVENT_END0("MY_SUBSYSTEM", "SomethingCostly") |
| 39 | // Note: our tools can't always determine the correct BEGIN/END pairs unless |
| 40 | // these are used in the same scope. Use ASYNC_BEGIN/ASYNC_END macros if you |
| 41 | // need them to be in separate scopes. |
| 42 | // |
| 43 | // A common use case is to trace entire function scopes. This |
| 44 | // issues a trace BEGIN and END automatically: |
| 45 | // void doSomethingCostly() { |
| 46 | // TRACE_EVENT0("MY_SUBSYSTEM", "doSomethingCostly"); |
| 47 | // ... |
| 48 | // } |
| 49 | // |
| 50 | // Additional parameters can be associated with an event: |
| 51 | // void doSomethingCostly2(int howMuch) { |
| 52 | // TRACE_EVENT1("MY_SUBSYSTEM", "doSomethingCostly", |
| 53 | // "howMuch", howMuch); |
| 54 | // ... |
| 55 | // } |
| 56 | // |
| 57 | // The trace system will automatically add to this information the |
| 58 | // current process id, thread id, and a timestamp in microseconds. |
| 59 | // |
| 60 | // To trace an asynchronous procedure such as an IPC send/receive, use |
| 61 | // ASYNC_BEGIN and ASYNC_END: |
| 62 | // [single threaded sender code] |
| 63 | // static int send_count = 0; |
| 64 | // ++send_count; |
| 65 | // TRACE_EVENT_ASYNC_BEGIN0("ipc", "message", send_count); |
| 66 | // Send(new MyMessage(send_count)); |
| 67 | // [receive code] |
| 68 | // void OnMyMessage(send_count) { |
| 69 | // TRACE_EVENT_ASYNC_END0("ipc", "message", send_count); |
| 70 | // } |
| 71 | // The third parameter is a unique ID to match ASYNC_BEGIN/ASYNC_END pairs. |
| 72 | // ASYNC_BEGIN and ASYNC_END can occur on any thread of any traced process. |
| 73 | // Pointers can be used for the ID parameter, and they will be mangled |
| 74 | // internally so that the same pointer on two different processes will not |
| 75 | // match. For example: |
| 76 | // class MyTracedClass { |
| 77 | // public: |
| 78 | // MyTracedClass() { |
| 79 | // TRACE_EVENT_ASYNC_BEGIN0("category", "MyTracedClass", this); |
| 80 | // } |
| 81 | // ~MyTracedClass() { |
| 82 | // TRACE_EVENT_ASYNC_END0("category", "MyTracedClass", this); |
| 83 | // } |
| 84 | // } |
| 85 | // |
| 86 | // Trace event also supports counters, which is a way to track a quantity |
| 87 | // as it varies over time. Counters are created with the following macro: |
| 88 | // TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter", g_myCounterValue); |
| 89 | // |
| 90 | // Counters are process-specific. The macro itself can be issued from any |
| 91 | // thread, however. |
| 92 | // |
| 93 | // Sometimes, you want to track two counters at once. You can do this with two |
| 94 | // counter macros: |
| 95 | // TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter0", g_myCounterValue[0]); |
| 96 | // TRACE_COUNTER1("MY_SUBSYSTEM", "myCounter1", g_myCounterValue[1]); |
| 97 | // Or you can do it with a combined macro: |
| 98 | // TRACE_COUNTER2("MY_SUBSYSTEM", "myCounter", |
| 99 | // "bytesPinned", g_myCounterValue[0], |
| 100 | // "bytesAllocated", g_myCounterValue[1]); |
| 101 | // This indicates to the tracing UI that these counters should be displayed |
| 102 | // in a single graph, as a summed area chart. |
| 103 | // |
| 104 | // Since counters are in a global namespace, you may want to disambiguate with a |
| 105 | // unique ID, by using the TRACE_COUNTER_ID* variations. |
| 106 | // |
| 107 | // By default, trace collection is compiled in, but turned off at runtime. |
| 108 | // Collecting trace data is the responsibility of the embedding |
| 109 | // application. In Chrome's case, navigating to about:tracing will turn on |
| 110 | // tracing and display data collected across all active processes. |
| 111 | // |
| 112 | // |
| 113 | // Memory scoping note: |
| 114 | // Tracing copies the pointers, not the string content, of the strings passed |
| 115 | // in for category_group, name, and arg_names. Thus, the following code will |
| 116 | // cause problems: |
| 117 | // char* str = strdup("importantName"); |
| 118 | // TRACE_EVENT_INSTANT0("SUBSYSTEM", str); // BAD! |
| 119 | // free(str); // Trace system now has dangling pointer |
| 120 | // |
| 121 | // To avoid this issue with the |name| and |arg_name| parameters, use the |
| 122 | // TRACE_EVENT_COPY_XXX overloads of the macros at additional runtime overhead. |
| 123 | // Notes: The category must always be in a long-lived char* (i.e. static const). |
| 124 | // The |arg_values|, when used, are always deep copied with the _COPY |
| 125 | // macros. |
| 126 | // |
| 127 | // When are string argument values copied: |
| 128 | // const char* arg_values are only referenced by default: |
| 129 | // TRACE_EVENT1("category", "name", |
| 130 | // "arg1", "literal string is only referenced"); |
| 131 | // Use TRACE_STR_COPY to force copying of a const char*: |
| 132 | // TRACE_EVENT1("category", "name", |
| 133 | // "arg1", TRACE_STR_COPY("string will be copied")); |
| 134 | // std::string arg_values are always copied: |
| 135 | // TRACE_EVENT1("category", "name", |
| 136 | // "arg1", std::string("string will be copied")); |
| 137 | // |
| 138 | // |
| 139 | // Convertable notes: |
| 140 | // Converting a large data type to a string can be costly. To help with this, |
| 141 | // the trace framework provides an interface ConvertableToTraceFormat. If you |
| 142 | // inherit from it and implement the AppendAsTraceFormat method the trace |
| 143 | // framework will call back to your object to convert a trace output time. This |
| 144 | // means, if the category for the event is disabled, the conversion will not |
| 145 | // happen. |
| 146 | // |
| 147 | // class MyData : public base::trace_event::ConvertableToTraceFormat { |
| 148 | // public: |
| 149 | // MyData() {} |
| 150 | // void AppendAsTraceFormat(std::string* out) const override { |
| 151 | // out->append("{\"foo\":1}"); |
| 152 | // } |
| 153 | // private: |
| 154 | // ~MyData() override {} |
| 155 | // DISALLOW_COPY_AND_ASSIGN(MyData); |
| 156 | // }; |
| 157 | // |
| 158 | // TRACE_EVENT1("foo", "bar", "data", |
| 159 | // std::unique_ptr<ConvertableToTraceFormat>(new MyData())); |
| 160 | // |
| 161 | // The trace framework will take ownership if the passed pointer and it will |
| 162 | // be free'd when the trace buffer is flushed. |
| 163 | // |
| 164 | // Note, we only do the conversion when the buffer is flushed, so the provided |
| 165 | // data object should not be modified after it's passed to the trace framework. |
| 166 | // |
| 167 | // |
| 168 | // Thread Safety: |
| 169 | // A thread safe singleton and mutex are used for thread safety. Category |
| 170 | // enabled flags are used to limit the performance impact when the system |
| 171 | // is not enabled. |
| 172 | // |
| 173 | // TRACE_EVENT macros first cache a pointer to a category. The categories are |
| 174 | // statically allocated and safe at all times, even after exit. Fetching a |
| 175 | // category is protected by the TraceLog::lock_. Multiple threads initializing |
| 176 | // the static variable is safe, as they will be serialized by the lock and |
| 177 | // multiple calls will return the same pointer to the category. |
| 178 | // |
| 179 | // Then the category_group_enabled flag is checked. This is a unsigned char, and |
| 180 | // not intended to be multithread safe. It optimizes access to AddTraceEvent |
| 181 | // which is threadsafe internally via TraceLog::lock_. The enabled flag may |
| 182 | // cause some threads to incorrectly call or skip calling AddTraceEvent near |
| 183 | // the time of the system being enabled or disabled. This is acceptable as |
| 184 | // we tolerate some data loss while the system is being enabled/disabled and |
| 185 | // because AddTraceEvent is threadsafe internally and checks the enabled state |
| 186 | // again under lock. |
| 187 | // |
| 188 | // Without the use of these static category pointers and enabled flags all |
| 189 | // trace points would carry a significant performance cost of acquiring a lock |
| 190 | // and resolving the category. |
