always-success clj

delay-exp clj

(delay-exp retry-count)

(delay-exp base retry-count)

Calculate an exponential delay in millis.

base - the base number to scale (default 100) retry-count - the number of previous attempts

delay-linear clj

(delay-linear factor retry-count)

Calculate a linear delay in millis.

factor - the linear factor to use retry-count - the number of previous attempts

disable clj

(disable spec)

init clj

(init {_r? :com.potetm.fusebox.retry/retry?
       _d :com.potetm.fusebox.retry/delay
       :as spec})

Initialize a retry.

spec is map containing: ::retry? - A predicate called after an exception to determine whether body should be retried. Takes three args: eval-count, exec-duration-ms, and the exception/failing value. ::delay - A function which calculates the delay in millis to wait prior to the next evaluation. Takes three args: eval-count, exec-duration-ms, and the exception/failing value. ::success? - (Optional) A function which takes a return value and determines whether it was successful. If false, body is retried. Defaults to (constantly true).

jitter clj

(jitter jitter-factor delay)

Randomly jitter a given delay.

jitter-factor - the decimal jitter percentage, between 0 and 1 delay - the base delay in millis

retry* clj deprecated

(retry* spec f)

DEPRECATED: This was an early mistake. It should have been named with-retry*.

shutdown clj

(shutdown spec)

with-retry clj macro

(with-retry bindings|spec & [spec|body & body :as b])

Evaluates body, retrying according to the provided retry spec.

with-retry* clj

(with-retry* {succ? :com.potetm.fusebox.retry/success?
              retry? :com.potetm.fusebox.retry/retry?
              delay :com.potetm.fusebox.retry/delay
              :or {succ? always-success}
              :as spec}
             f)
