Changelog

2.5.0

Those changes are not released yet.

• In the functional API, invoke the wrapped function callback on abort and emit
  an abort event. This makes it possible to detect when abort is called.
• Add a method on the function API, call.retryIf(predicate), which specifies
  a predicate used to determine whether a given error is retriable or not. The
  default behavior is unaffected, errors remain retriable by default.

2.4.1

• Add support for specifying the factor to use in the ExponentialStrategy.

2.4.0

• Replace FunctionCall.getResults by FunctionCall.getLastResult to avoid
  storing intermediary results forever as this may lead to memory exhaustion
  when used in conjunction with an infinite number of backoffs.
• Add FunctionCall.getNumRetries which returns the number of times the
  wrapped function was retried.

2.3.0

• Add four new methods to FunctionCall to query the state of the call.
• isPending
• isRunning
• isCompleted
• isAborted

2.2.0

• To match Backoff default behavior, FunctionCall no longer sets a
  default failAfter of 5, i.e. the maximum number of backoffs is now
  unbounded by default.

2.1.0

• Backoff.backoff now accepts an optional error argument that is re-emitted
  as the last argument of the backoff and fail events. This provides some
  context to the listeners as to why a given backoff operation was attempted.
• The backoff event emitted by the FunctionCall class now contains, as its
  last argument, the error that caused the backoff operation to be attempted.
  This provides some context to the listeners as to why a given backoff
  operation was attempted.

2.0.0

• FunctionCall.call renamed into FunctionCall.start.
• backoff.call no longer invokes the wrapped function on nextTick. That
  way, the first attempt is not delayed until the end of the current event
  loop.

1.2.1

• Make FunctionCall.backoffFactory a private member.

1.2.0

• Add backoff.call and the associated FunctionCall class.

1.1.0

• Add a Backoff.failAfter.

1.0.0

• Rename start and done events backoff and ready.
• Remove deprecated backoff.fibonnaci.

0.2.1

• Create backoff.fibonacci.
• Deprecate backoff.fibonnaci.
• Expose fibonacci and exponential strategies.

0.2.0

• Provide exponential and fibonacci backoffs.

0.1.0

• Change initialTimeout and maxTimeout to initialDelay and maxDelay.
• Use fibonnaci backoff.
