I was wondering how the Rep/Req setup would work with a server and multiple
clients making requests, as there is nothing in the API which signals which
client the server is replying to when it get a request. However it looks
like the API is keeping some internal state which make it kind of work.
When Im saying kind of work, I mean it works as long as Im not trying to do
anything fancy on the server side. However if the server implement an event
loop (or is MT) and the reply becomes a deferred operation resolved later, then
there is no way of directing the reply back to the original client.
c1 c2 server
req1 ------------>defer -+
req2-----> + |
res2<----- + V
req1 ready
<- - - - ?-- res1 +
What I see is that the res1 actually goes to c2 instead of c1 which is probably
caused by an internal global state of the connection set to be the last active
connection.
Is there an API for getting and setting the state of the connection on the
server side so that the server can programmaticly solve this -- or is there are
better solution for this?
This is particularly a really bad problem for non-blocking programming which is
common these days such as in nodejs.
