[usocket-devel] fix for connection-stream external-format in CCL
by Vsevolod Dyomkin 19 Feb '13

19 Feb '13

HI, I've noticed a problem in the CCL backend, when the socket is created not with the default external-format but with NIL external-format which causes the fallback to ISO-8859-1 and is rather unfortunate. What's even worse is that it's very hard to alter the format, while initializing it from ccl:*default-external-format* makes it possible to control this parameter. So here's a small change that solves the problem. It's against v.0.5.5, but I've looked at the code for 0.6.1 and didn't see any change there. If someone points me to the sources, I can make a proper patch. diff -u openmcl-new.lisp openmcl.lisp --- openmcl-new.lisp 2013-02-18 19:18:25.482382100 +0200 +++ openmcl.lisp 2013-02-18 19:16:24.586378860 +0200 @@ -97,6 +97,7 @@ :local-port local-port :format (to-format element-type) :deadline deadline + :external-format ccl:*default-external-format* :nodelay nodelay :connect-timeout timeout))) (make-stream-socket :stream mcl-sock :socket mcl-sock))) @@ -107,6 +108,7 @@ :local-host (when local-host (host-to-hostname local-host)) :local-port local-port :input-timeout timeout + :external-format ccl:*default-external-format* :format :binary)) (usocket (make-datagram-socket mcl-sock))) (when (and host port) Best, Vsevolod Dyomkin +38-096-111-41-56 skype, twitter: vseloved

[usocket-devel] Add (socket-option ... :tcp-no-delay) for stream-usocket?
by Jan Moringen 14 Feb '13

14 Feb '13

Hi, I like the new socket-option functions and I think methods socket-option (stream-usocket (eql :tcp-no-delay)) (setf socket-option) (t stream-usocket (eql :tcp-no-delay)) should be added. This addition would enable stream sockets obtained from socket-accept to operate with TCP_NODELAY. As far as I can see, this is currently not possible without unportable code like (setf (sb-bsd-sockets::sockopt-tcp-nodelay (usocket::socket s)) t) What do you think? Kind regards, Jan
