always-success cljs

default-ex cljs

(default-ex n ed v)

The default ::exception fn. Always returns an ExceptionInfo with fusebox ex-data and the last exception as the cause.

delay-exp cljs

(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 cljs

(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 cljs

(disable spec)

init cljs

(init {_r? :com.potetm.fusebox.cljs.retry/retry?
       _d :com.potetm.fusebox.cljs.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. The last failing value can be found under the ::retry/val key in the thrown ex-info's data. Defaults to (constantly true). ::exception - (Optional) A function which returns the exception to throw once ::retry? returns false. Defaults to an ExceptionInfo with fusebox ex-data and the last exception as the cause. See also wrap-ex-after-retry andno-wrap-ex. Takes three args: eval-count, exec-duration-ms, and the exception/failing value.

jitter cljs

(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

no-wrap-ex cljs

(no-wrap-ex n ed v)

An ::exception fn. Only wraps with an if the failing value was not an Exception (i.e. ::success? returned false).

resolve-after cljs

(resolve-after ms)

shutdown cljs

(shutdown spec)

with-retry clj/s macro

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

Evaluates body which returns a promise, retrying according to the provided retry spec.

with-retry* cljs

(with-retry* {succ? :com.potetm.fusebox.cljs.retry/success?
              retry? :com.potetm.fusebox.cljs.retry/retry?
              delay :com.potetm.fusebox.cljs.retry/delay
              exception :com.potetm.fusebox.cljs.retry/exception
              :or {succ? always-success exception default-ex}}
             f)

wrap-ex-after-retry cljs

(wrap-ex-after-retry n ed v)

An ::exception fn. Only wraps with an ExceptionInfo if a retry was attempted or if the failing value was not an Exception (i.e. ::success? returned false).
