3.2.2 #

  • Document types and release mode (special thanks to SwissCheese5)
  • More error handling at communication points
  • Use lower log levels for internal Squadron log messages
  • Added test coverage

3.2.1 #

  • Document the new logging feature
  • Make sendRequest() async in browser channel (implementation closer to that of native channel)
  • Add a timestamp to pool workers to record the time when it was assigned its last task
  • Sort pool workers to distribute tasks to those that have the largest capacity and the oldest timestamp
  • Add command property to WorkerException
  • Reorganized the test folder
  • Recompiled test Web workers

3.2.0 #

  • Added a logging mechanism to facilitate debugging Squadron's internals
  • Reworked connection flow between main program and worker
  • Reworked task scheduling
  • Fixed issue https://github.com/d-markey/squadron/issues/3
  • Added tests for logging and workers failing to initialize

3.1.4 #

  • Implemented cancellation token to enable worker task notification that cancellation has occured.
  • Implemented TimeOutToken, CancellableToken and CompositeToken.
  • Updated README.md.
  • Added unit tests.

3.1.0 #

  • Several minor changes (some possibly breaking changes but easy to fix).
  • Split library into squadron_service.dart (worker services only), squadron_worker.dart (worker services and workers without pool) vs. squadron.dart (worker services, workers and pools).
  • Split Channel into Channel (used to send a WorkerRequest) and WorkerChannel (used to send a WorkerResponse).
  • Added ConcurrencySettings to eventually replace minWorkers, maxWorkers and maxParallel.
  • Added WorkerPool.execute() (will eventually replace WorkerPool.compute()).
  • Added WorkerPool.scheduleTask() to schedule a ValueTask. Result will be accessible from future ValueTask.value.
  • Added WorkerPool.scheduleStream() to schedule a StreamTask. Results will be accessible from stream StreamTask.stream.
  • ValueTask and StreamTask provide information on task execution (eg. status, wait time, execution time...).
  • Added WorkerPool.cancel() to support worker task cancellation.
  • Updated README.md.
  • Added unit tests.

3.0.0 #

  • Split library into squadron_service.dart (worker services only), squadron.dart (worker services and workers without pool) vs. squadron_pool.dart (worker services, workers and pools).
  • Moved connect() and process() from Worker to WorkerService.
  • Provided the run() function to facilitate implementation of platform workers.
  • Adapted tests and examples.
  • Updated README.md.

2.0.2 #

  • Single test code base for both platforms.
  • Added BitCoin service to test live network access from workers (courtesy of coindesk.com).
  • Added PiDigits service (related to https://github.com/d-markey/squadron/issues/1).
  • Retaining attempts based on manually operating a browser to run tests in /web (different test code base) and /test/browser-tests (same test code base).

2.0.1 #

  • Remove dependency on js package.

2.0.0 #

  • This version supports workers running in Isolates as well as Web Workers.
  • Platform implementations are now more straightforward thanks to Worker.connect() and Worker.process().
  • See examples on how to scaffold Services, Squadron Workers and platform workers.
  • Added tests for Web Workers (run with "dart run build_runner serve -r" and point your browser to http://localhost:8080/index.html).

1.0.2 #

  • Added support for minimum count of workers in pool.
  • Make sure Isolate is killed when the worker is stopped.
  • Keep track of stats from stopped workers.
  • Update tests & examples (proper error handling, command map, worker monitoring).

1.0.1 #

  • Improve error handling.
  • Improve documentation.
  • Add unit tests.

1.0.0 #

  • Initial version.
