[usocket-devel] Fwd: [usocket-cvs] r245 - usocket/trunk/backend
by Erik Huelsmann 23 Jul '08

23 Jul '08

Hi Douglas, I recently added some functionality in usocket and even though I think I could have copy-pasted from the CMU backend, I want to verify with you if this is true. The functions I added: - get-host-name (as you can see in the commit mail below based on copy-paste from CMU) - wait-for-input-internal which I didn't copy-paste yet. I would be especially gratefull if you could copy-paste and verify the latter for me and optionally even supply a patch. For testing of the multiplexing code, I use this 'script': (load "asdf.lisp") (asdf:oos 'asdf:load-op :usocket) (defvar sockets nil) (defparameter crlf (format nil "~C~C" #\Return #\Linefeed)) (defparameter host "mirror.w3media.nl") (defparameter offset-path "/apache") (dotimes (i 10) (let ((s (usocket:socket-connect host 80))) (format (usocket:socket-stream s) "GET http://~A~A/httpd/httpd-2.0.~A.tar.gz HTTP/1.0~%~%" host offset-path (+ 50 i)) (force-output (usocket:socket-stream s)) (push s sockets))) (let ((buffer (make-array 8192 :element-type 'character))) (loop (let ((ready (usocket:wait-for-input sockets :timeout 15))) (unless ready (sleep 1) (format t "No ready sockets!~%")) (dolist (r ready) (format t "Reading from ~A~%" r) (read-sequence buffer (usocket:socket-stream r)))))) HTH and thanks for your reaction in advance! bye, Erik. ---------- Forwarded message ---------- From: ehuelsmann(a)common-lisp.net <ehuelsmann(a)common-lisp.net> Date: May 18, 2007 12:03 AM Subject: [usocket-cvs] r245 - usocket/trunk/backend To: usocket-cvs(a)common-lisp.net Author: ehuelsmann Date: Thu May 17 18:03:55 2007 New Revision: 245 Modified: usocket/trunk/backend/scl.lisp Log: Add cl-smtp 'requirement': get-host-name (SCL backend); needs verification.

[usocket-devel] accept on sbcl may return nil
by Attila Lendvai 29 Jul '07

29 Jul '07

hi, looking at the code of accept in sbcl, it seems that it may return with nil in case of sockint::EAGAIN or sockint::EINTR. what should usocket do in this case? loop until non-nil is returned or return nil? the latter might be more useful when dealing with timeouts, but i'm no socket expert of any kind. -- attila

by Yaroslav Kavenchuk 21 Jun '07

Hi! Support of a proxy in the usocket is meaningful? It will add dependence on cl-base64. -- WBR, Yaroslav Kavenchuk.
