[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] LispWorks and UDP
by Chun Tian (binghe) 31 Jan '08

31 Jan '08

Hi, usocket developer Recently I wrote a LispWorks UDP support package for my pure lisp SNMP package. I use the FFI function which already in LispWorks to do a UDP job, and implement a interface which very like the exist TCP interface. You can find my code here: URL: https://cl-net-snmp.svn.sourceforge.net/svnroot/cl-net-snmp/lispworks-udp/t… Seems LispWorks, Ltd. didn't have any plan for UDP support, this package may help for usocket to implement a universal socket interface. I'll be glad for usocket to use my code, you can asdf depend it or just merge it. Regards, Chun TIAN (binghe)

[usocket-devel] socket-connect raises non-obvious conditions when given a bad host
by Ryan Davis 12 Jan '08

12 Jan '08

When I try to use socket-connect with a host that can't be resolved, it throws an unhelpful error: Couldn't write to #<SB-SYS:FD-STREAM for "a socket" {C0286C1}>: Broken pipe [Condition of type SB-INT:SIMPLE-STREAM-ERROR] Restarts: 0: [ABORT] Return to SLIME's top level. 1: [TERMINATE-THREAD] Terminate this thread (#<THREAD "repl-thread" {B35FB79}>) Backtrace: 0: (SB-IMPL::SIMPLE-STREAM-PERROR "Couldn't write to ~s" #<SB-SYS:FD-STREAM for "a socket" {C0286C1}> 32) 1: (SB-IMPL::SIMPLE-STREAM-PERROR "Couldn't write to ~s" #<SB-SYS:FD-STREAM for "a socket" {C0286C1}> 32) 2: (FORCE-OUTPUT #<SB-SYS:FD-STREAM for "a socket" {C0286C1}>) 3: (USOCKET-BAD-ERROR) Here is my test program: (defun usocket-bad-error () (let ((s (usocket:socket-stream (usocket:socket-connect "doesntexist.example.com" 80)))) (format s "GET / HTTP/1.1") (force-output s);;error thrown here s)) Looking through the usocket code, what I would have liked here is a bad-host-name condition thrown that I could handle. I initially thought a good spot for this would be in socket-connect, if the ip variable is nil, but upon looking at the usocket source so more, I'm not sure if there's a better place for that. Also, I was going to add this as a ticket on the usocket trac, but I don't have permission to do that.

[usocket-devel] The spam
by Marijn Haverbeke 11 Jan '08

11 Jan '08

Hey Eric, The junk-mail brigade seems to have discovered this list. I had the same with postmodern-devel -- when spammers pretend to be sending mail from an @common-lisp.net domain, the list will automatically let them through. Dig through the list options, and you will find a way to disable this feature. Cheers, Marijn
