isolate_pool_executor 2.2.1

Just like a thread pool, but with isolates. The Isolate Pool Executor is a tool in Dart for managing concurrent tasks by limiting and reusing isolates to optimize performance.

2.2.1

• Fix the bug where the keepAliveTime parameter of IsolatePoolExecutor is ineffective.

2.2.0

• Optimize the content of the lints.

2.1.0

• customizeTaskInvoker adds new parameters: taskLabel, what, and tag, derived from the corresponding parameters in compute.

Breaking Changes

• The tag parameter in compute will be sent to the isolate. Note that you should verify whether the parameter value can be sent. https://api.dart.dev/dart-isolate/SendPort/send.html

2.0.0

• Allow customization of task execution in Isolate.
• Fix onIsolateCreated bug
• Improve the ability to capture task exceptions
• Modify debugLabel name

1.2.3

• Allow obtaining the content of the message before submitting the task for calculating the order.

1.2.2

• Fixed the task execution exception when taskQueueInIsolate is set to true in SingleIsolate.

1.2.1

• In non-release mode (determined by assert), the default creation waiting time is changed to 6 seconds. In release mode, it remains unchanged at 3 seconds.

1.2.0

• Added a new parameter onIsolateCreateTimeoutTimesDoNotCreateNew. If isolate creation times out n consecutive times, no new isolates will be created, and only the already initialized isolates will be used. If no timeouts occur, the pool will use the isolates with m cores, along with other cached isolates.
• This feature can help alleviate this issue. See the README for more details.

1.1.5

• Added the immediatelyStartedCore parameter to IsolatePoolExecutor and IsolatePoolExecutor.newFixedIsolatePool, allowing customization of the number of isolates that start immediately.

1.1.4

• The isolateValues in the onIsolateCreated callback is now non-nullable and will default to an empty map.
• Added isShutdown to the pool to check if shutdown has been called.
• Updated the README to include instructions on calling MethodChannel from an isolate in Flutter.

1.1.3

• The return value of compute is now wrapped in TaskFuture, allowing you to view the current taskId and related tag.

1.1.2

• Added support for specifying a debugLabel for IsolatePoolExecutor.

1.1.1

• Added a new onIsolateCreated parameter, which is called immediately after an isolate is created. This, along with isolateValues, allows initialization of data for the isolate.

Example: Introducing background isolate channels.

• Interaction with isolates now uses RawReceivePort.

1.1.0

• Optimized initial isolate startup by directly assigning tasks, reducing one send operation, and improved idle state detection for isolates.
• Added timeout validation for isolate startup due to this known issue.
• Added a parameter launchCoreImmediately (default false), which starts all core isolates immediately.

1.0.6

• Fixed QueueEmpty in newCachedIsolatePool to prevent adding any tasks.

1.0.5

• Threw an exception when sending tasks failed.
• Added global exception handling for workers in isolates.

1.0.4

• Added common extension methods.

1.0.3

• Optimized communication times in IsolateNoCache, bringing performance close to Isolate.run.

1.0.2

• Added support for storing map values during isolate initialization.
• Optimized isolate exit mechanism when keepAliveTime is set to 0.
• Improved data transfer between isolates.

1.0.1

• Refined code structure. When using a single isolate, tasks can be sent directly to the isolate without a queue.

1.0.0

• First version completed with 3 common creation methods implemented by default.
