v2.6.0

Compare Source

What's Changed

• chore(deps): bump actions/checkout from 5 to 6 by @​dependabot[bot] in #​131
• feat(disable-queue): Allow disabling task queue by setting it to 0 by @​alitto in #​132 (Thanks @​korotin 🙌)
• feat(optional-panic-recovery): Add option to disable panic recovery by @​alitto in #​133 (Thanks @​snichols 🙌)

Breaking Changes

• Setting the queue size option to zero (0) via WithQueueSize(0) now disables the task queue altogether (all task submissions block until a worker becomes available unless the pool is set to non-blocking mode). Before this change, setting queue size to 0 would cause the queue to be unbounded. Pools are still unbounded by default, but now there's a constant that can be used to set queue size to unbounded explicitly. E.g. pond.NewPool(10, pond.WithQueueSize(pond.Unbounded)).

Pull requests

• fix(pool): avoid race conditions when a task is submitted while the pool is stopping by @​alitto in #​105
• feat(pool): add non-blocking submission methods and dropped tasks metric by @​alitto in #​107

Changes

• Ensure closed atomic bool is toggled and checked while holding the mutex to avoid race conditions.
• Ensure workersWaitGroup.Add() is always called while holding the mutex to avoid race conditions.
• Improve comments on submit methods to clarify the behavior when the pool is stopped.
• Refactor trySubmit method to make it simpler and more clear.
• Centralize worker launch in a new method called launchWorker.
• Replace subpoolSubmit with subpoolWorker method.
• Add methods to submit individual tasks in a non-blocking fashion (TrySubmit and TrySubmitErr). Requested in #​103
• Expose new DroppedTasks metric that reflects the number of tasks that were not executed because the queue was full. Issue reported in #​100
• SubmittedTasks metric now includes dropped tasks and it stops being updated once the pool is stopped.

Fixes

• Decrement workerCount counter when the pool context is cancelled.
• Resize() now supports setting maxConcurrency to 0 (no limit)

What's new in v2?

Version 2 of pond introduces many improvements and new features:

• Unbounded Task Queues: Task queues are now unbounded by default, simplifying pool creation.
• Task Submission with Results: New APIs allow tasks to return results, enhancing flexibility.
• Awaitable Task Completion: Tasks can now be awaited, providing better control over task execution.
• Type Safe APIs: Improved type safety for tasks that return errors or results.
• Panics Recovery: Panics during task execution are captured and returned as errors, allowing graceful error handling.
• Subpools: Create subpools with a fraction of the parent pool's workers for specific tasks.
• Default Pool: A global default pool is available for task submission without explicit pool creation.
