Subject: [2.0.4-scala] play.api.libs.iteratee.Enumerator.fromFi le and large file
Print | View thread | Show original | Report this message | Find messages by this author

Enumerator.fromFile uses Enumerator.fromCallback that includes method
step(it: Iteratee[E, A]) (in method apply). Method "step" is recursive but
isn't tail-recursive so large file can throw OutOfMemory exception, can't
it?
I'd like to implement enumerator that can wait for data in some file (e.g.
log file). It will periodically check file and sends Input.Empty in
Iteratee if new data isn't available. But if I make a similar
implementation of enumerator it won't work in a limited amount of memory.
Is there the better decision?
