Future
Hello,
I am using future this way:
(doall (map #(future () (range 1 max-size))
When the max-size is small like around 6, if I don't print (println (doall
(map #(future () (range 1 max-size))), the
result becomes empty
(Without print)
renata@renata:~/$ lein run
ranking {}
(With print)
renata@renata:~/$$ lein run
(#object[clojure.core$future_call$reify__6962 0x6492fab5 {:status :ready,
:val {:2 0, :4 0.0, :5 0, :1 2.5}}]
#object[clojure.core$future_call$reify__6962 0x2c532cd8 {:status :ready,
:val {:2 0}}] #object[clojure.core$future_call$reify__6962 0x294e5088
{:status :ready, :val {:2 0, :4 0.0, :5 0, :1 2.5, :3 1.0}}]
#object[clojure.core$future_call$reify__6962 0x51972dc7 {:status :ready,
:val {:2 0, :4 0.0}}] #object[clojure.core$future_call$reify__6962
0x3700ec9c {:status :ready, :val {:2 0, :4 0.0, :5 0}}])
ranking {"1":2.5,"3":1.0,"5":0,"4":0.0,"2":0}
I am using (shutdown-agents) after the doall...
Any ideas why? I think it is because the futures aren't ready when
(shutdown-agents) executes.
(When the max-size is big, run normally)
There is a way that I can wait for print the result until all futures are
ready?
Thanks!

Re: Future
Not sure what's going on with shutdown-agents, but you could call (run!
deref ...) to wait for all the futures to complete.

Re: Future
(doall (pmap (range ...))) may be a viable approach also,
depending on the behaviour you want.
