isolate_manager: ^5.1.0 copied to clipboard

Create multiple long-lived isolates for the Functions, supports Worker on the Web (with the effective generator) and WASM compilation.

5.1.0 #

  • Stable now.

5.1.0-rc.1 #

  • Improve README.

5.1.0-rc #

  • Add IsolateManagerShared to be able to compute the multiple Functions.

  • Generate the shared Workers by using the @isolateManagerSharedWorker annotation.

  • Able to generate a custom Worker from a customFunction by using the @isolateManagerCustomWorker annotation.

  • Improve the README.

  • Various improvements and optimizations.

  • The generator:

    • The default dart run isolate_manager:generate command will generates both single and shared Workers.
    • Use dart run isolate_manager:generate --single to generate only the single functions (@isolateManagerWorker and @isolateManagerCustomWorker annotations).
    • Use dart run isolate_manager:generate_shared --shared to generate only the shared functions (@isolateManagerSharedWorker annotation).
  • This is an rc version because the various improvements may affect some edge cases so I want to make sure it's fully backward-compatible

5.0.0-rc.1 #

  • Bump sdk to ^3.3.0.
  • Remove autoInitialize parameter.
  • Remove deprecated methods.
  • MIGRATION: All isolate functions MUST be update and all Workers MUST be recompiled:
    • If you're using the IsolateManagerFunction.workerFunction, you need to re-generate the JS for the Web Worker (compile from Dart to JS). The IsolateManagerFunction.customFunction will be automatically applied.
    • If you're using the old method, you need to send a initialized signal from an Isolate and a Worker:
      • Custom function of an Isolate: add the controller.initialized(); to the end of the function.

        • Before:

          void customFunction(dynamic params) {
            final controller = IsolateManagerController(params);
            controller.onIsolateMessage.then((value){
              // ...
            });
          }
          
        • After:

          void customFunction(dynamic params) async {
            // Do something sync or async here
          
            final controller = IsolateManagerController(params); 
            controller.onIsolateMessage.then((value){
              // ...
            });
          
            controller.initialized(); // <--
          }
          
      • On the Web Worker: add jsSendMessage(IsolateState.initialized.toJson()); to the end of the main method.

        • Before:

          void main() {
            callbackToStream('onmessage', (MessageEvent e) {
              return js_util.getProperty(e, 'data');
            }).listen((message) {
              // ...
            });  
          }
          
        • After:

          void main() async {
            // Do something sync or async here
          
            callbackToStream('onmessage', (MessageEvent e) {
              return js_util.getProperty(e, 'data');
            }).listen((message) {
              // ...
            });
          
            jsSendMessage(IsolateState.initialized.toJson()); // <--
          }
          

4.3.1 #

  • Export the IsolateState.

4.3.0 #

  • Support WASM.
  • Add benchmark tests.
  • Deprecate the IsolateFunctionHelper in favor of the IsolateManagerFunction.
  • Improve the IsolateManagerFunction.workerFunction.
  • [Experiment and Optional] Able to send an initialized signal from the isolate to the main app to ensure that the isolate is ready to receive the messages from the main app. The Migration Steps:
    • Step 1:
      • If you're using the IsolateManagerFunction.workerFunction, you need to re-generate the JS for the Web Worker (compile from Dart to JS). The IsolateManagerFunction.customFunction will be automatically applied.

      • If you're using the old method, you need to send a initialized signal from an Isolate and a Worker:

        • Custom function of an Isolate: add the controller.initialized(); to the end of the function.

          • Before:

            void customFunction(dynamic params) {
              final controller = IsolateManagerController(params);
              controller.onIsolateMessage.then((value){
                // ...
              });
            }
            
          • After:

            void customFunction(dynamic params) async {
              // Do something sync or async here
            
              final controller = IsolateManagerController(params); 
              controller.onIsolateMessage.then((value){
                // ...
              });
            
              controller.initialized(); // <--
            }
            
        • On the Web Worker: add jsSendMessage(IsolateState.initialized.toJson()); to the end of the main method.

          • Before:

            void main() {
              callbackToStream('onmessage', (MessageEvent e) {
                return js_util.getProperty(e, 'data');
              }).listen((message) {
                // ...
              });  
            }
            
          • After:

            void main() async {
              // Do something sync or async here
            
              callbackToStream('onmessage', (MessageEvent e) {
                return js_util.getProperty(e, 'data');
              }).listen((message) {
                // ...
              });
            
              jsSendMessage(IsolateState.initialized.toJson()); // <--
            }
            
      • Step 2: Update the create and createCustom method:

        • Before:
        final isolate = await IsolateManager.create(
          function, 
          workerName: 'function',
        );
        
        • After:
        final isolate = await IsolateManager.create(
          function, 
          workerName: 'function',
          autoInitialize: false, // <--
        );

  • The method .start() is now optional, the plugin will automatically call this method when using .compute for the first time, so you have 3 way to create the instance:

    IsolateManager<int> isolateManager = IsolateManager.create(
      fibonacci,
      concurrent: 4,
    );
    
    await isolateManager.start();
    
    1. Use start without await:
    IsolateManager<int> isolateManager = IsolateManager.create(
      fibonacci,
      concurrent: 4,
    );
    
    isolateManager.start();
    
    1. Use start when creating the instance:
    IsolateManager<int> isolateManager = IsolateManager.create(
      fibonacci,
      concurrent: 4,
    )..start();
