[iolib-devel] Bug when using READ-LINE on non-blocking fds
by Chaitanya Gupta 08 Feb '09

08 Feb '09

Hi, Iolib behaves in the following way when using READ-LINE with a non-blocking fd: ;; *client-stream is the stream associated with a client connected to our server IRCD> *client-stream #<active IPv6 stream socket connected to ::ffff:127.0.0.1/41460 {1004D5D451}> IRCD> (fd-non-blocking *) T ;; client sends the string "foo" down the socket, no newline is sent IRCD> (ignore-errors (read-line *client-stream)) NIL #<System-Error EWOULDBLOCK(11) "Resource temporarily unavailable"> ;; client sends the string "bar", followed by a newline IRCD> (ignore-errors (read-line *client-stream)) "bar" NIL So, essentially, the string "foo" is lost. Shouldn't the correct behaviour be to wait till a newline arrives on the socket? Chaitanya

[iolib-devel] [RELEASE] Version 0.6.0
by Stelian Ionescu 06 Feb '09

06 Feb '09

18 months after 0.5.4, I've released 0.6.0: a tarball and its GPG signature are available from http://common-lisp.net/project/iolib/download.shtml . Preliminary documentation can be found here: http://common-lisp.net/project/iolib/manual , but only for the socket library. My next goals are to finish the new stream library(Zeta-streams) and the pathname library. -- Stelian Ionescu a.k.a. fe[nl]ix Quidquid latine dictum sit, altum videtur.

[iolib-devel] io.multiplex::timer
by Matthew Mondor 06 Feb '09

06 Feb '09

Probably that the timer type should be exported as well in pkgdcl.lisp considering that to use exported remove-timer objects of type timer have to be provided... Thus, it's useful to define a struct or class holding an object of type (or timer null) to remove-timer if t later on (if set to a timer returned by add-timer)? Also, is there, or was there recently a known bug that prevents remove-timer from actually disabling a timer? I have a timer in repeat mode which appears to be triggered even after it was removed... Thanks, -- Matt

[iolib-devel] Abstract sockets
by Julian Stecklina 03 Feb '09

03 Feb '09

Hello, the attached patch fixes abstract sockets for Linux. It least it tries as it does not work: strace output from dbus-monitor: socket(PF_FILE, SOCK_STREAM, 0) = 3 connect(3, {sa_family=AF_FILE, path=@"/tmp/dbus-RhgMDI9FXg"...}, 23) = 0 strace output from my app using iolib: socket(PF_FILE, SOCK_STREAM, 0) = 5 connect(5, {sa_family=AF_FILE, path=@"/tmp/dbus-RhgMDI9FXg"...}, 110) = -1 ECONNREFUSED (Connection refused) It seems as if connect (and bind) have to be passed "exact" sizes as addrlen parameter. But what is a good (i.e. portable) way to compute these? Using (+ 3 (length address)) (counting the address family word, the zero byte, and the string) would be quite a hack... Regards, -- Julian Stecklina Well, take it from an old hand: the only reason it would be easier to program in C is that you can't easily express complex problems in C, so you don't. - Erik Naggum (in comp.lang.lisp)
