Langohr is a small Clojure RabbitMQ client.

2.3.2 is a minor feature and bug fix release based on community feedback on connection recovery.

Changes between Langohr 2.2.1 and 2.3.2


langohr.core/automatically-recover? is deprecated

Use langohr.core/automatic-recovery-enabled? instead.

Recovery Predicates

langohr.core/automatic-recovery-enabled? and langohr.core/automatic-topology-recovery-enabled? are new predicate functions that return true if automatic connection and topology recovery, respectively, is enabled for the provided connection.

Topology Recovery Fails Quickly

Topology recovery now fails quickly, raising com.novemberain.langohr.recovery.TopologyRecoveryException which carries the original (cause) exception.

Previously if recovery of an entity failed, other entities were still recovered. Now topology recovery fails on the first exception, making issues more visible.

Automatic Recovery Can Be Disabled By Passing nil

Automatic recovery options now respect both false and nil values.
