Type definitions and Cluster.changeTimeout()

• Added TypeScript type definitions thanks to @alexperovich
• Added Cluster.changeTimeout()

Fixed missing args in 'dropped' event from schedule()

• Propagate the arguments coming from promise()/promisePriority() into the task runner so that the dropped event shows the arguments that were given to Bottleneck.

Safer stopAll()

• Changed internal representation of jobs tracking from a sparse array to an object. Fixes #25
• Instead of disabling submit/submitPriority/schedule/schedulePriority, stopAll() now makes those functions automatically reject any new requests with a descriptive error. This should save a lot of frustration and help users debug their programs.

'idle' event, removeAllListeners(), nbRunning()

• Added the idle event. It is emitted when both nbQueued() and nbRunning() drop to 0, which means there is nothing running and nothing queued up.
• Added the removeAllListeners() method which follows the same pattern as the standard Node.js method of the same name. It supports an optional event name as first argument.
• Added the nbRunning() method which returns the number of requests currently running in the limiter.

Fixed issue with callbacks and rejectOnDrop

• Fixed an issue where the callback arguments when using rejectOnDrop with submit and submitPriority would be shifted when the job would be dropped.

Added rejectOnDrop

• Added a new constructor parameter: rejectOnDrop. When set to true, dropped jobs will be failed/rejected with the Error This job has been dropped by Bottleneck.

Changed high water default

• Default highWater value went from 0 (unlimited) to -1 (unlimited). This makes it possible to create limiters that drop anything that would have gone into the queue, in order words setting highWater to 0 will create a limiter that will only accept requests that will be executed immediately.

Added support for events

• Added .on('empty', callback)
• Added .on('dropped', callback)

Fixed documentation

• Bottleneck.Promise = ... --> Bottleneck.prototype.Promise

v1.10.1
