Instead, we refer to objects through + * handles, which are known to the garbage collector and updated + * automatically when the object is moved. Handles should be passed + * by value (except in cases like out-parameters) and should never be + * allocated on the heap. + * + * Most functions in the Dart Embedding API return a handle. When a + * function completes normally, this will be a valid handle to an + * object in the Dart VM heap. This handle may represent the result of + * the operation or it may be a special valid handle used merely to + * indicate successful completion. Note that a valid handle may in + * some cases refer to the null object. + * + * --- Error handles --- + * + * When a function encounters a problem that prevents it from + * completing normally, it returns an error handle (See Dart_IsError). + * An error handle has an associated error message that gives more + * details about the problem (See Dart_GetError). + * + * There are four kinds of error handles that can be produced, + * depending on what goes wrong: + * + * - Api error handles are produced when an api function is misused. + * This happens when a Dart embedding api function is called with + * invalid arguments or in an invalid context. + * + * - Unhandled exception error handles are produced when, during the + * execution of Dart code, an exception is thrown but not caught. + * Prototypically this would occur during a call to Dart_Invoke, but + * it can occur in any function which triggers the execution of Dart + * code (for example, Dart_ToString). + * + * An unhandled exception error provides access to an exception and + * stacktrace via the functions Dart_ErrorGetException and + * Dart_ErrorGetStackTrace. + * + * - Compilation error handles are produced when, during the execution + * of Dart code, a compile-time error occurs. As above, this can + * occur in any function which triggers the execution of Dart code. + * + * - Fatal error handles are produced when the system wants to shut + * down the current isolate. + * + * --- Propagating errors --- + * + * When an error handle is returned from the top level invocation of + * Dart code in a program, the embedder must handle the error as they + * see fit. Often, the embedder will print the error message produced + * by Dart_Error and exit the program. + * + * When an error is returned while in the body of a native function, + * it can be propagated up the call stack by calling + * Dart_PropagateError, Dart_SetReturnValue, or Dart_ThrowException. + * Errors should be propagated unless there is a specific reason not + * to. If an error is not propagated then it is ignored. For + * example, if an unhandled exception error is ignored, that + * effectively "catches" the unhandled exception. Fatal errors must + * always be propagated. + * + * When an error is propagated, any current scopes created by + * Dart_EnterScope will be exited. + * + * Using Dart_SetReturnValue to propagate an exception is somewhat + * more convenient than using Dart_PropagateError, and should be + * preferred for reasons discussed below. + * + * Dart_PropagateError and Dart_ThrowException do not return. Instead + * they transfer control non-locally using a setjmp-like mechanism. + * This can be inconvenient if you have resources that you need to + * clean up before propagating the error. + * + * When relying on Dart_PropagateError, we often return error handles + * rather than propagating them from helper functions. Consider the + * following contrived example: + * + * 1 Dart_Handle isLongStringHelper(Dart_Handle arg) { + * 2 intptr_t* length = 0; + * 3 result = Dart_StringLength(arg, &length); + * 4 if (Dart_IsError(result)) { + * 5 return result; + * 6 } + * 7 return Dart_NewBoolean(length > 100); + * 8 } + * 9 + * 10 void NativeFunction_isLongString(Dart_NativeArguments args) { + * 11 Dart_EnterScope(); + * 12 AllocateMyResource(); + * 13 Dart_Handle arg = Dart_GetNativeArgument(args, 0); + * 14 Dart_Handle result = isLongStringHelper(arg); + * 15 if (Dart_IsError(result)) { + * 16 FreeMyResource(); + * 17 Dart_PropagateError(result); + * 18 abort(); // will not reach here + * 19 } + * 20 Dart_SetReturnValue(result); + * 21 FreeMyResource(); + * 22 Dart_ExitScope(); + * 23 } + * + * In this example, we have a native function which calls a helper + * function to do its work. On line 5, the helper function could call + * Dart_PropagateError, but that would not give the native function a + * chance to call FreeMyResource(), causing a leak. Instead, the + * helper function returns the error handle to the caller, giving the + * caller a chance to clean up before propagating the error handle. + * + * When an error is propagated by calling Dart_SetReturnValue, the + * native function will be allowed to complete normally and then the + * exception will be propagated only once the native call + * returns. This can be convenient, as it allows the C code to clean + * up normally. + * + * The example can be written more simply using Dart_SetReturnValue to + * propagate the error. + * + * 1 Dart_Handle isLongStringHelper(Dart_Handle arg) { + * 2 intptr_t* length = 0; + * 3 result = Dart_StringLength(arg, &length); + * 4 if (Dart_IsError(result)) { + * 5 return result + * 6 } + * 7 return Dart_NewBoolean(length > 100); + * 8 } + * 9 + * 10 void NativeFunction_isLongString(Dart_NativeArguments args) { + * 11 Dart_EnterScope(); + * 12 AllocateMyResource(); + * 13 Dart_Handle arg = Dart_GetNativeArgument(args, 0); + * 14 Dart_SetReturnValue(isLongStringHelper(arg)); + * 15 FreeMyResource(); + * 16 Dart_ExitScope(); + * 17 } + * + * In this example, the call to Dart_SetReturnValue on line 14 will + * either return the normal return value or the error (potentially + * generated on line 3). The call to FreeMyResource on line 15 will + * execute in either case. + * + * --- Local and persistent handles --- + * + * Local handles are allocated within the current scope (see + * Dart_EnterScope) and go away when the current scope exits. Unless + * otherwise indicated, callers should assume that all functions in + * the Dart embedding api return local handles. + * + * Persistent handles are allocated within the current isolate. They + * can be used to store objects across scopes. Persistent handles have + * the lifetime of the current isolate unless they are explicitly + * deallocated (see Dart_DeletePersistentHandle). + * The type Dart_Handle represents a handle (both local and persistent). + * The type Dart_PersistentHandle is a Dart_Handle and it is used to + * document that a persistent handle is expected as a parameter to a call + * or the return value from a call is a persistent handle. + * + * FinalizableHandles are persistent handles which are auto deleted when + * the object is garbage collected. It is never safe to use these handles + * unless you know the object is still reachable. + * + * WeakPersistentHandles are persistent handles which are automatically set + * to point Dart_Null when the object is garbage collected.
