Release 2.0.0

This is a major reworking of breaker internals. All circuit breakers are now Breaker objects, and the trip semantics are defined by an assigned ShouldTrip function.

Added

• All circuit breakers are now a Breaker with trip semantics handled by a TripFunc
• NewConsecutiveBreaker
• NewRateBreaker
• ConsecFailures
• ErrorRate
• Success
• Successes
• Retry logic now uses cenkalti/backoff, exponential backoff by default

Deprecated

• Nothing

Removed

• TrippableBreaker, ThresholdBreaker, FrequencyBreaker, TimeoutBreaker; all handled by Breaker now
• NewFrequencyBreaker, replaced by NewConsecutiveBreaker
• NewTimeoutBreaker, time out semantics are now handled by Call()
• NoOp(), use a Breaker with no TripFunc instead

Release 1.1.2

For a FrequencyBreaker, Failures() should return the count since the duration start, even after resetting.

Using Failures() in a monitoring system will always show 0 if traffic is doing Reset() on successful attempts faster than your sampling rate.

Release 1.1.1

Only send the reset event when the breaker was in a tripped state.

Release 1.1.0

This release re-exports the Panel's Circuits map.

Release 1.0.0

This is the 1.0.0 release. The API is considered stable and backward compatibility will be maintained.
