Blocking behavior of >!! ?
The documentation for >!! reads:
-
clojure.core.async/>!!
([port val])
puts a val into port. nil values are not allowed. Will block if no
buffer space is available. Returns true unless port is already closed.
I have a case where I believe that the channel has no buffer, I park a
"pseudothread" in a go block reading off that channel via !!:
(let [c (chan) ;; NO BUFFER!
d (go (!! c 42)] ;; blocking write to c, will unpark c's pseudothread
(println {:c-coughs-up '(this will hang (!! will block if there is no buffer space available *and* if there is no
*rendezvous *available, that is, no pseudothread parked waiting for http://groups.google.com/group/clojure?hl=en
