-# The V8 public C++ API
-
-# Overview
-
-The V8 public C++ API aims to support four use cases:
-
-1. Enable applications that embed V8 (called the embedder) to configure and run
-   one or more instances of V8.
-2. Expose ECMAScript-like capabilities to the embedder.
-3. Enable the embedder to interact with ECMAScript by exposing API objects.
-4. Provide access to the V8 debugger (inspector).
-
-# Configuring and running an instance of V8
-
-V8 requires access to certain OS-level primitives such as the ability to
-schedule work on threads, or allocate memory.
-
-The embedder can define how to access those primitives via the v8::Platform
-interface. While V8 bundles a basic implementation, embedders are highly
-encouraged to implement v8::Platform themselves.
-
-Currently, the v8::ArrayBuffer::Allocator is passed to the v8::Isolate factory
-method, however, conceptually it should also be part of the v8::Platform since
-all instances of V8 should share one allocator.
-
-Once the v8::Platform is configured, an v8::Isolate can be created. All
-further interactions with V8 should explicitly reference the v8::Isolate they
-refer to. All API methods should eventually take an v8::Isolate parameter.
-
-When a given instance of V8 is no longer needed, it can be destroyed by
-disposing the respective v8::Isolate. If the embedder wishes to free all memory
-associated with the v8::Isolate, it has to first clear all global handles
-associated with that v8::Isolate.
-
-# ECMAScript-like capabilities
-
-In general, the C++ API shouldn't enable capabilities that aren't available to
-scripts running in V8. Experience has shown that it's not possible to maintain
-such API methods in the long term. However, capabilities also available to
-scripts, i.e., ones that are defined in the ECMAScript standard are there to
-stay, and we can safely expose them to embedders.
-
-The C++ API should also be pleasant to use, and not require learning new
-paradigms. Similarly to how the API exposed to scripts aims to provide good
-ergonomics, we should aim to provide a reasonable developer experience for this
-API surface.
-
-ECMAScript makes heavy use of exceptions, however, V8's C++ code doesn't use
-C++ exceptions. Therefore, all API methods that can throw exceptions should
-indicate so by returning a v8::Maybe<> or v8::MaybeLocal<> result,
-and by taking a v8::Local<v8::Context> parameter that indicates in which
-context a possible exception should be thrown.
-
-# API objects
-
-V8 allows embedders to define special objects that expose additional
-capabilities and APIs to scripts. The most prominent example is exposing the
-HTML DOM in Blink. Other examples are e.g. node.js. It is less clear what kind
-of capabilities we want to expose via this API surface. As a rule of thumb, we
-want to expose operations as defined in the WebIDL and HTML spec: we
-assume that those requirements are somewhat stable, and that they are a
-superset of the requirements of other embedders including node.js.
-
-Ideally, the API surfaces defined in those specs hook into the ECMAScript spec
-which in turn guarantees long-term stability of the API.
-
-# The V8 inspector
-
-All debugging capabilities of V8 should be exposed via the inspector protocol.
-The exception to this are profiling features exposed via v8-profiler.h.
-Changes to the inspector protocol need to ensure backwards compatibility and
-commitment to maintain.

-/**
- * This file provides additional API on top of the default one for making
- * API calls, which come from embedder C++ functions. The functions are being
- * called directly from optimized code, doing all the necessary typechecks
- * in the compiler itself, instead of on the embedder side. Hence the "fast"
- * in the name. Example usage might look like:
- *
- * \code
- *    void FastMethod(int param, bool another_param);
- *
- *    v8::FunctionTemplate::New(isolate, SlowCallback, data,
- *                              signature, length, constructor_behavior
- *                              side_effect_type,
- *                              &v8::CFunction::Make(FastMethod));
- * \endcode
- *
- * By design, fast calls are limited by the following requirements, which
- * the embedder should enforce themselves:
- *   - they should not allocate on the JS heap;
- *   - they should not trigger JS execution.
- * To enforce them, the embedder could use the existing
- * v8::Isolate::DisallowJavascriptExecutionScope and a utility similar to
- * Blink's NoAllocationScope:
- * https://source.chromium.org/chromium/chromium/src/+/master:third_party/blink/renderer/platform/heap/thread_state_scopes.h;l=16
- *
- * Due to these limitations, it's not directly possible to report errors by
- * throwing a JS exception or to otherwise do an allocation. There is an
- * alternative way of creating fast calls that supports falling back to the
- * slow call and then performing the necessary allocation. When one creates
- * the fast method by using CFunction::MakeWithFallbackSupport instead of
- * CFunction::Make, the fast callback gets as last parameter an output variable,
- * through which it can request falling back to the slow call. So one might
- * declare their method like:
- *
- * \code
- *    void FastMethodWithFallback(int param, FastApiCallbackOptions& options);
- * \endcode
- *
- * If the callback wants to signal an error condition or to perform an
- * allocation, it must set options.fallback to true and do an early return from
- * the fast method. Then V8 checks the value of options.fallback and if it's
- * true, falls back to executing the SlowCallback, which is capable of reporting
- * the error (either by throwing a JS exception or logging to the console) or
- * doing the allocation. It's the embedder's responsibility to ensure that the
- * fast callback is idempotent up to the point where error and fallback
- * conditions are checked, because otherwise executing the slow callback might
- * produce visible side-effects twice.
- *
- * An example for custom embedder type support might employ a way to wrap/
- * unwrap various C++ types in JSObject instances, e.g:
- *
- * \code
- *
- *    // Helper method with a check for field count.
- *    template <typename T, int offset>
- *    inline T* GetInternalField(v8::Local<v8::Object> wrapper) {
- *      assert(offset < wrapper->InternalFieldCount());
- *      return reinterpret_cast<T*>(
- *          wrapper->GetAlignedPointerFromInternalField(offset));
- *    }
- *
- *    class CustomEmbedderType {
- *     public:
- *      // Returns the raw C object from a wrapper JS object.
- *      static CustomEmbedderType* Unwrap(v8::Local<v8::Object> wrapper) {
- *        return GetInternalField<CustomEmbedderType,
- *                                kV8EmbedderWrapperObjectIndex>(wrapper);
- *      }
- *      static void FastMethod(v8::ApiObject receiver_obj, int param) {
- *        v8::Object* v8_object = reinterpret_cast<v8::Object*>(&api_object);
- *        CustomEmbedderType* receiver = static_cast<CustomEmbedderType*>(
- *          receiver_obj->GetAlignedPointerFromInternalField(
- *            kV8EmbedderWrapperObjectIndex));
- *
- *        // Type checks are already done by the optimized code.
- *        // Then call some performance-critical method like:

- * For instance if {object} is exposed via a global "obj" variable,

- *   - bool
- *   - int32_t
- *   - uint32_t

- *  - bool
- *  - int32_t
- *  - uint32_t
- *  - int64_t
- *  - uint64_t
- *  - float32_t
- *  - float64_t
- *
- * The 64-bit integer types currently have the IDL (unsigned) long long
- * semantics: https://heycam.github.io/webidl/#abstract-opdef-converttoint
- * In the future we'll extend the API to also provide conversions from/to
- * BigInt to preserve full precision.
- * The floating point types currently have the IDL (unrestricted) semantics,
- * which is the only one used by WebGL. We plan to add support also for
- * restricted floats/doubles, similarly to the BigInt conversion policies.
- * We also differ from the specific NaN bit pattern that WebIDL prescribes
- * (https://heycam.github.io/webidl/#es-unrestricted-float) in that Blink
- * passes NaN values as-is, i.e. doesn't normalize them.
- *
- * To be supported types:
- *  - arrays of C types
- *  - arrays of embedder types

- * This class serves as a base class for recording event-based metrics in V8.
- * There a two kinds of metrics, those which are expected to be thread-safe and
- * whose implementation is required to fulfill this requirement and those whose
- * implementation does not have that requirement and only needs to be
- * executable on the main thread. If such an event is triggered from a
- * background thread, it will be delayed and executed by the foreground task
- * runner.
- *
- * The thread-safe events are listed in the V8_THREAD_SAFE_METRICS_EVENTS
- * macro above while the main thread event are listed in
- * V8_MAIN_THREAD_METRICS_EVENTS above. For the former, a virtual method
- * AddMainThreadEvent(const E& event, v8::Context::Token token) will be
- * generated and for the latter AddThreadSafeEvent(const E& event).
- *
- * Thread-safe events are not allowed to access the context and therefore do
- * not carry a context ID with them. These IDs can be generated using
- * Recorder::GetContextId() and the ID will be valid throughout the lifetime
- * of the isolate. It is not guaranteed that the ID will still resolve to
- * a valid context using Recorder::GetContext() at the time the metric is
- * recorded. In this case, an empty handle will be returned.
- *
- * The embedder is expected to call v8::Isolate::SetMetricsRecorder()
- * providing its implementation and have the virtual methods overwritten
- * for the events it cares about.

-   *   overhead.
-   * - Fixed number of CallOnWorkerThread() calls that split the work and might
-   *   run for a long time. This is problematic when many components post

-   *   the scheduler lacks context to be fair to multiple same-priority requests
-   *   and/or ability to request lower priority work to yield when high priority
-   *   work comes in.
-   * A canonical implementation of |job_task| looks like:
-   * class MyJobTask : public JobTask {
-   *  public:
-   *   MyJobTask(...) : worker_queue_(...) {}

-   *
-   * PostJob() and methods of the returned JobHandle/JobDelegate, must never be
-   * called while holding a lock that could be acquired by JobTask::Run or
-   * JobTask::GetMaxConcurrency -- that could result in a deadlock. This is

-   * thread (A=>B/B=>A deadlock) and [2] JobTask::Run or
-   * JobTask::GetMaxConcurrency may be invoked synchronously from JobHandle
-   * (B=>JobHandle::foo=>B deadlock).

-# The V8 public C++ API
-
-# Overview
-
-The V8 public C++ API aims to support four use cases:
-
-1. Enable applications that embed V8 (called the embedder) to configure and run
-   one or more instances of V8.
-2. Expose ECMAScript-like capabilities to the embedder.
-3. Enable the embedder to interact with ECMAScript by exposing API objects.
-4. Provide access to the V8 debugger (inspector).
-
-# Configuring and running an instance of V8
-
-V8 requires access to certain OS-level primitives such as the ability to
-schedule work on threads, or allocate memory.
-
-The embedder can define how to access those primitives via the v8::Platform
-interface. While V8 bundles a basic implementation, embedders are highly
-encouraged to implement v8::Platform themselves.
-
-Currently, the v8::ArrayBuffer::Allocator is passed to the v8::Isolate factory
-method, however, conceptually it should also be part of the v8::Platform since
-all instances of V8 should share one allocator.
-
-Once the v8::Platform is configured, an v8::Isolate can be created. All
-further interactions with V8 should explicitly reference the v8::Isolate they
-refer to. All API methods should eventually take an v8::Isolate parameter.
-
-When a given instance of V8 is no longer needed, it can be destroyed by
-disposing the respective v8::Isolate. If the embedder wishes to free all memory
-associated with the v8::Isolate, it has to first clear all global handles
-associated with that v8::Isolate.
-
-# ECMAScript-like capabilities
-
-In general, the C++ API shouldn't enable capabilities that aren't available to
-scripts running in V8. Experience has shown that it's not possible to maintain
-such API methods in the long term. However, capabilities also available to
-scripts, i.e., ones that are defined in the ECMAScript standard are there to
-stay, and we can safely expose them to embedders.
-
-The C++ API should also be pleasant to use, and not require learning new
-paradigms. Similarly to how the API exposed to scripts aims to provide good
-ergonomics, we should aim to provide a reasonable developer experience for this
-API surface.
-
-ECMAScript makes heavy use of exceptions, however, V8's C++ code doesn't use
-C++ exceptions. Therefore, all API methods that can throw exceptions should
-indicate so by returning a v8::Maybe<> or v8::MaybeLocal<> result,
-and by taking a v8::Local<v8::Context> parameter that indicates in which
-context a possible exception should be thrown.
-
-# API objects
-
-V8 allows embedders to define special objects that expose additional
-capabilities and APIs to scripts. The most prominent example is exposing the
-HTML DOM in Blink. Other examples are e.g. node.js. It is less clear what kind
-of capabilities we want to expose via this API surface. As a rule of thumb, we
-want to expose operations as defined in the WebIDL and HTML spec: we
-assume that those requirements are somewhat stable, and that they are a
-superset of the requirements of other embedders including node.js.
-
-Ideally, the API surfaces defined in those specs hook into the ECMAScript spec
-which in turn guarantees long-term stability of the API.
-
-# The V8 inspector
-
-All debugging capabilities of V8 should be exposed via the inspector protocol.
-The exception to this are profiling features exposed via v8-profiler.h.
-Changes to the inspector protocol need to ensure backwards compatibility and
-commitment to maintain.
