EhCache default parameters

[Tim Brigginshaw]

Hi,

It seems to me that the code in EhCacheApi, together with the default from AsyncCaheApi conspire to hide the values of timeToLive and timeToIdle from the ehcache.xml configuration file.


def set(key: String, value: Any, expiration: Duration = Duration.Inf): Future[Done]

def set(key: String, value: Any, expiration: Duration): Future[Done] = {
   val element = new Element(key, value)
   expiration match {
     case infinite: Duration.Infinite => element.setEternal(true)
     case finite: FiniteDuration =>
       val seconds = finite.toSeconds
       if (seconds <= 0) {
         element.setTimeToLive(1)
       } else if (seconds > Int.MaxValue) {
         element.setTimeToLive(Int.MaxValue)
       } else {
         element.setTimeToLive(seconds.toInt)
       }
   }
   Future.successful {
     cache.put(element)
     Done
   }
 }

TimeToLive can be set on an element by element basis, but timeToIdle cannot  - and appears to default to 0 (no time to idle) instead of the value in the config (although I cannot see where this happens explicitly)

It would be nice in a future version of Play  to have a way of using all the values in ehcache.xml out of the box without having to write a new cache module.

Thanks
