executor 2.2.1

Executes async tasks with a configurable maximum concurrency and rate.

Changelog

2.2.1

• Updated code to Dart 2.7.0 and latest lints.
• Fix: task completion updates the running count immediately.

2.2.0

• Removed new keyword, and updated to follow package:pedantic rules.
• Executor.join will register Future.catchError on task futures, preventing uncaught exceptions from blocking further execution.
• Simplified execution and trigger mechanism.

2.1.2

• Using package:stack_trace to chain async stacktraces when task fails.

2.1.1

• Improved design on loop and scheduling, preserving caller stacktrace with full details.

2.1.0

• Removed Timers to schedule tasks, using a simple loop instead.
• Better distribution for rate-limited executions.

2.0.0

1.0.1

• Dart2 compatibility with package:dart2_constant.

1.0.0

Breaking changes

• Removed deprecated member limit.
• Renamed ExecutorTask -> AsyncTask, return value to FutureOr.
• Renamed Rate.limit -> Rate.maximum.

New features

• Added Executor.onChange. Clients can use this to monitor the current scheduledCount and queue more tasks to ensure Executor is running on full capacity.

Housekeeping

• Added example.
• Added a few tests.

0.1.2

• Expose internal stats: runningCount, waitingCount, scheduledCount.
• Enable sync-points with join(), which allows to track the completion of the currently running (and optionally the waiting) tasks.

0.1.1

• Fix missing heartbeat check on Executor.close(), without it the Future might not have completed.

0.1

• start-rate limit support
• renamed limit to concurrency (leaving old field, marked deprecated)
