// Forward declares classes that are generated at build-time from protos.
// First of all, why are we forward declaring at all?
//  1. Chromium diverges from the Google style guide on this, because forward
//     declarations typically make build times faster, and that's a desirable
//     property for a large and complex codebase.
//  2. Adding #include to build-time-generated headers from headers typically
//     creates subtle build errors that are hard to spot in GN. This is because
//     once a standard header (say foo.h) has an #include "protos/foo.gen.h",
//     the build target that depends on foo.h needs to depend on the genrule
//     that generates foo.gen.h. This is achievable using public_deps in GN but
//     is not testable / enforceable, hence too easy to get wrong.

// Historically the classes below used to be generated from the corresponding
// .proto(s) at CL *check-in* time (!= build time) in the ::perfetto namespace.
// Nowadays we have code everywhere that assume the right class is
// ::perfetto::TraceConfig or the like. Back then other headers could just
// forward declared ::perfetto::TraceConfig. These days, the real class is
// ::perfetto::protos::gen::TraceConfig and core/trace_config.h aliases that as
// using ::perfetto::TraceConfig = ::perfetto::protos::gen::TraceConfig.
// In C++ one cannot forward declare a type alias (but only the aliased type).
// Hence this header, which should be used every time one wants to forward
// declare classes like TraceConfig.

// The overall plan is that, when one of the classes below is needed:
// The .h file includes this file.
// The .cc file includes perfetto/tracing/core/trace_config.h (or equiv). That
// header will pull the full declaration from trace_config.gen.h and will also
// setup the alias in the ::perfetto namespace.

#define INCLUDE_PERFETTO_TRACING_INTERCEPTOR_H_

// An interceptor is used to redirect trace packets written by a data source
// into a custom backend instead of the normal Perfetto tracing service. For
// example, the console interceptor prints all trace packets to the console as
// they are generated. Another potential use is exporting trace data to another
// tracing service such as Android ATrace or Windows ETW.
//
// An interceptor is defined by subclassing the perfetto::Interceptor template:
//
// class MyInterceptor : public perfetto::Interceptor<MyInterceptor> {
//  public:
//   ~MyInterceptor() override = default;
//
//   // This function is called for each intercepted trace packet. |context|
//   // contains information about the trace packet as well as other state
//   // tracked by the interceptor (e.g., see ThreadLocalState).
//   //
//   // Intercepted trace data is provided in the form of serialized protobuf
//   // bytes, accessed through the |context.packet_data| field.
//   //
//   // Warning: this function can be called on any thread at any time. See
//   // below for how to safely access shared interceptor data from here.
//   static void OnTracePacket(InterceptorContext context) {
//     perfetto::protos::pbzero::TracePacket::Decoder packet(
//         context.packet_data.data, context.packet_data.size);
//     // ... Write |packet| to the desired destination ...
//   }
// };
//
// An interceptor should be registered before any tracing sessions are started.
// Note that the interceptor also needs to be activated through the trace config
// as shown below.
//
//   perfetto::InterceptorDescriptor desc;
//   desc.set_name("my_interceptor");
//   MyInterceptor::Register(desc);
//
// Finally, an interceptor is enabled through the trace config like this:
//
//   perfetto::TraceConfig cfg;
//   auto* ds_cfg = cfg.add_data_sources()->mutable_config();
//   ds_cfg->set_name("data_source_to_intercept");   // e.g. "track_event"
//   ds_cfg->mutable_interceptor_config()->set_name("my_interceptor");
//
// Once an interceptor is enabled, all data from the affected data sources is
// sent to the interceptor instead of the main tracing buffer.
//
// Interceptor state
// =================
//
// Besides the serialized trace packet data, the |OnTracePacket| interceptor
// function can access three other types of state:
//
// 1. Global state: this is no different from a normal static function, but care
//    must be taken because |OnTracePacket| can be called concurrently on any
//    thread at any time.
//
// 2. Per-data source instance state: since the interceptor class is
//    automatically instantiated for each intercepted data source, its fields
//    can be used to store per-instance data such as the trace config. This data
//    can be maintained through the OnSetup/OnStart/OnStop callbacks:
//
//    class MyInterceptor : public perfetto::Interceptor<MyInterceptor> {
//     public:
//      void OnSetup(const SetupArgs& args) override {
//        enable_foo_ = args.config.interceptor_config().enable_foo();
//      }
//
//      bool enable_foo_{};
//    };
//
//    In the interceptor function this data must be accessed through a scoped
//    lock for safety:
//
//    class MyInterceptor : public perfetto::Interceptor<MyInterceptor> {
//      ...
//      static void OnTracePacket(InterceptorContext context) {
//        auto my_interceptor = context.GetInterceptorLocked();
//        if (my_interceptor) {
//           // Access fields of MyInterceptor here.
//           if (my_interceptor->enable_foo_) { ... }
//        }
//        ...
//      }
//    };
//
//    Since accessing this data involves holding a lock, it should be done
//    sparingly.
//
// 3. Per-thread/TraceWriter state: many data sources use interning to avoid
//    repeating common data in the trace. Since the interning dictionaries are
//    typically kept individually for each TraceWriter sequence (i.e., per
//    thread), an interceptor can declare a data structure with lifetime
//    matching the TraceWriter:
//
//    class MyInterceptor : public perfetto::Interceptor<MyInterceptor> {
//     public:
//      struct ThreadLocalState
//          : public perfetto::InterceptorBase::ThreadLocalState {
//        ThreadLocalState(ThreadLocalStateArgs&) override = default;
//        ~ThreadLocalState() override = default;
//
//        std::map<size_t, std::string> event_names;
//      };
//    };
//
//    This per-thread state can then be accessed and maintained in
//    |OnTracePacket| like this:
//
//    class MyInterceptor : public perfetto::Interceptor<MyInterceptor> {
//      ...
//      static void OnTracePacket(InterceptorContext context) {
//        // Updating interned data.
//        auto& tls = context.GetThreadLocalState();
//        if (parsed_packet.sequence_flags() & perfetto::protos::pbzero::
//                TracePacket::SEQ_INCREMENTAL_STATE_CLEARED) {
//          tls.event_names.clear();
//        }
//        for (const auto& entry : parsed_packet.interned_data().event_names())
//          tls.event_names[entry.iid()] = entry.name();
//
//        // Looking up interned data.
//        if (parsed_packet.has_track_event()) {
//          size_t name_iid = parsed_packet.track_event().name_iid();
//          const std::string& event_name = tls.event_names[name_iid];
//        }
//        ...

// These classes provide a JSON-inspired way to write structed data into traces.
//
// Each TracedValue can be consumed exactly once to write a value into a trace
// using one of the Write* methods.
//
// Write* methods fall into two categories:
// - Primitive types (int, string, bool, double, etc): they just write the
//   provided value, consuming the TracedValue in the process.
// - Complex types (arrays and dicts): they consume the TracedValue and
//   return a corresponding scoped object (TracedArray or TracedDictionary).
//   This scope then can be used to write multiple items into the container:
//   TracedArray::AppendItem and TracedDictionary::AddItem return a new
//   TracedValue which then can be used to write an element of the
//   dictionary or array.
//
// To define how a custom class should be written into the trace, users should
// define one of the two following functions:
// - Foo::WriteIntoTrace(TracedValue) const
//   (preferred for code which depends on perfetto directly)
// - perfetto::TraceFormatTraits<T>::WriteIntoTrace(
//       TracedValue, const T&);
//   (should be used if T is defined in a library which doesn't know anything
//   about tracing).
//
//
// After definiting a conversion method, the object can be used directly as a
// TRACE_EVENT argument:
//
// Foo foo;
// TRACE_EVENT("cat", "Event", "arg", foo);
//
// Examples:
//
// TRACE_EVENT("cat", "event", "params", [&](perfetto::TracedValue context)
// {
//   auto dict = std::move(context).WriteDictionary();
//   dict->Add("param1", param1);
//   dict->Add("param2", param2);
//   ...
//   dict->Add("paramN", paramN);
//
//   {
//     auto inner_array = dict->AddArray("inner");
//     inner_array->Append(value1);
//     inner_array->Append(value2);
//   }
// });

// Track events are recorded on a timeline track, which maintains the relative

// track (ThreadTrack), which is by default where all track events are written.
// Thread tracks are grouped under their hosting process (ProcessTrack).

// Events which aren't strictly scoped to a thread or a process, or don't
// correspond to synchronous code execution on a thread can use a custom
// track (Track, ThreadTrack or ProcessTrack). A Track object can also
// optionally be parented to a thread or a process.
//
// A track is represented by a uuid, which must be unique across the entire

// use a matching id to tie the begin and end events together:
//
//   TRACE_EVENT_BEGIN("category", "AsyncEvent", perfetto::Track(8086));
//   ...

// This file contains a set of macros designed for instrumenting applications
// with track event trace points. While the underlying TrackEvent API can also
// be used directly, doing so efficiently requires some care (e.g., to avoid
// evaluating arguments while tracing is disabled). These types of optimizations
// are abstracted away by the macros below.
//
// ================
// Quickstart guide
// ================
//
//   To add track events to your application, first define your categories in,
//   e.g., my_tracing.h:
//
//       PERFETTO_DEFINE_CATEGORIES(
//           perfetto::Category("base"),
//           perfetto::Category("v8"),
//           perfetto::Category("cc"));
//
//   Then in a single .cc file, e.g., my_tracing.cc:
//
//       #include "my_tracing.h"
//       PERFETTO_TRACK_EVENT_STATIC_STORAGE();
//
//   Finally, register track events at startup, after which you can record
//   events with the TRACE_EVENT macros:
//
//       #include "my_tracing.h"
//
//       int main() {
//         perfetto::TrackEvent::Register();
//
//         // A basic track event with just a name.
//         TRACE_EVENT("category", "MyEvent");
//
//         // A track event with (up to two) debug annotations.
//         TRACE_EVENT("category", "MyEvent", "parameter", 42);
//
//         // A track event with a strongly typed parameter.
//         TRACE_EVENT("category", "MyEvent", [](perfetto::EventContext ctx) {
//           ctx.event()->set_foo(42);
//           ctx.event()->set_bar(.5f);
//         });
//       }
//
//  Note that track events must be nested consistently, i.e., the following is
//  not allowed:
//
//    TRACE_EVENT_BEGIN("a", "bar", ...);
//    TRACE_EVENT_BEGIN("b", "foo", ...);
//    TRACE_EVENT_END("a");  // "foo" must be closed before "bar".
//    TRACE_EVENT_END("b");
//
// ====================
// Implementation notes
// ====================
//
// The track event library consists of the following layers and components. The
// classes the internal namespace shouldn't be considered part of the public
// API.
