Changelog

1.1.54

  • Improve handling of Vectors when adding entries

1.1.53

  • improve memory use

1.1.52

  • fixes a bug with concurrent loads causing some of them to return nil as a result

1.1.51

  • DO NOT USE
  • add check for cyclical loads to caffeine cache, e.g. cached function calling itself with same parameters, this now throws StackOverflowError, which is the error you'd get in this situation with uncached function
  • improved performance

1.1.50

  • added option of using SoftReferences in caffeine cache
  • fixed reload-guards? var not being redefinable

1.1.45

  • add getters/setters to MultiCache for the delegate/upstream cache, also add clojure functions to access these properties to memento.multi namespace
  • moved CacheKey to memento.base Java package

1.1.44

  • fix bug which would have the cache return nil when concurrently accessing a value being calculated that ends being uncacheable

1.1.42

  • big internal changes now uses Java objects for most things for smaller memory profile and smaller callstack
  • significant improvements to callstack size for cached call
  • This is breaking changes for any implementation, shouldn't affect users
  • Fixes issue where namespace scan would stack caches on the same function over and over if called multiple times

Here is an example of previous callstack of recursively cached call (without ret-fn):

	at myns$myfn.invoke(myns.clj:12)
	at clojure.lang.AFn.applyToHelper(AFn.java:160)
	at clojure.lang.AFn.applyTo(AFn.java:144)
	at clojure.core$apply.invokeStatic(core.clj:667)
	at clojure.core$apply.invoke(core.clj:662)
	at memento.caffeine.CaffeineCache$fn__2536.invoke(caffeine.clj:122)
	at memento.caffeine.CaffeineCache.cached(caffeine.clj:121)
	at memento.mount.UntaggedMountPoint.cached(mount.clj:50)
	at memento.mount$bind$fn__2432.doInvoke(mount.clj:119)
	at clojure.lang.RestFn.applyTo(RestFn.java:137)
	at clojure.lang.AFunction$1.doInvoke(AFunction.java:31)
	at clojure.lang.RestFn.invoke(RestFn.java:436)
	at myns$myfn.invokeStatic(myns.clj:17)
	at myns$myfn.invoke(myns.clj:12)

And callstack after:

	at myns$myfn.invoke(myns.clj:12)
	at clojure.lang.AFn.applyToHelper(AFn.java:160)
	at memento.caffeine.CaffeineCache$fn__2052.invoke(caffeine.clj:120)
	at memento.caffeine.CaffeineCache.cached(caffeine.clj:119)
	at memento.mount.CachedFn.invoke(CachedFn.java:110)
	at myns$myfn.invokeStatic(myns.clj:17)
	at myns$myfn.invoke(myns.clj:12)
