[erlang-questions] : sctp_peeloff() support in OTP

[Valentin Micic]

One thing puzzles me: is there support for {active, once} in gen_sctp, as it
would assume head-of-line blocking? Or maybe I should ask a different
question: if {active, once} is to be supported, how one could go about
implementing it without defeating the purpose behind SCTP?

I am thinking:

(1) {active, [once, StreamNo, TargetPID]} 
    {active, [once, default, TargetPID]}

As well as:

(2)  {active, [true, StreamNo, TargetPID]}
     {active, [true, default, TargetPID]}

Where:
 - StreamNo represents a stream of interest;
 - TargetPID, a PID to which traffic received over StreamNo should be
forwarded to.
 - default specify what to do with streams that are not explicitly
referenced.

Wouldn't this imply SCTP peel-off functionality?

V.

PS
In a case you're already doing this -- my apologies for reinventing a hot
water.

Well, what do you know, I had already fixed it but forgot
all about it. But our test suites really could test it
much more...

What about you open source users. Is active mode working
fine for you? Under heavy load?

In that case Peeloff is a possible next large feature to implement,
if not the only missing large feature...? Anybody missing
something other important?
