[usocket-devel] What if a usocket instance be garbage collected?
by Chun Tian (binghe) 01 Oct '08

01 Oct '08

Hi, usocket devel If a usocket instance has been garbage collected (or just cannot refer to it, i. e. lost it by set the variable to new value), does anyone (either usocket or CL platform) will consider closing the correspond socket fd automatically? I know at least one CL platform, LispWorks, has some related API (HCL:ADD-SPECIAL-FREE-ACTION) [1], and I want to use it in my UDP applications. Just don't know if this will be a common feature to be considered by usocket itself. Any opinions? --binghe [1] http://www.lispworks.com/documentation/lw51/LWUG/html/lwuser-149.htm#pgfId-…

Hi Lars! Thanks for the report. Sorry for the delay; I finally committed your fix. I've applied a similar fix to SOCKET-LISTEN. Bye, Erik.

[usocket-devel] ECL on Windows: winsock.h or winsock2.h
by Anton Vodonosov 30 Aug '08

30 Aug '08

Hello. I have just tried to compile usocket with ECL (HEAD version), Windows and MSVC. It fails. Changing #include <winsock2.h> to #include <winsock.h> in the backend/sbcl.lisp made it working. Does it works for someone with winsock2.h? Best regards, -Anton

[usocket-devel] bind interface?
by Chris Dean 04 Aug '08

04 Aug '08

I'm new to usocket and would like to bind a socket to a specific address. (bind as in http://www.istild.com/man-pages/man2/bind.2.html) Is there an api for that? Cheers, Chris Dean

[usocket-devel] Rebranching 0.4.x branch && road to 0.4.x release
by Erik Huelsmann 31 Jul '08

31 Jul '08

Over the last month(s), many commits have happened on trunk/ which should also be in 0.4.x. On inspection, out of 30 or 40 commits, only 4 should *not* be on 0.4.x. (The UDP socket changes.) With r405, basically everything I want to have in 0.4.x is now on trunk/. (Except - ofcourse - the SCL changes Douglas is looking into, but that can come later too.) For efficiency, I have decided to rebranch the 0.4.x branch and afterwards undoing the UDP socket changes on that branch. When that's done - at the end of this week - all that needs to happen for 0.4.x is testing. So, anybody who's interested in a release with WAIT-FOR-INPUT and :local-host binding for SOCKET-CONNECT, please provide your feedback starting Monday August 4th: we need to asses the quality of the code currently up for release on the branch! Thanks for your patience, it's been a big task to get this release done! And of course: thanks to everybody who invested time into providing feedback as well as patches! Bye, Erik.

[usocket-devel] Working the hans/ branch into trunk
by Erik Huelsmann 27 Jul '08

27 Jul '08

Hi Hans, I have a question regarding the hans/ branch: in usocket.lisp, you added the SET-SOCKET-TIMEOUTS function. However, other than the default method from the 'defgeneric' form, it doesn't look very much implemented anywhere. Did you find this is at this time not possible? If so, shouldn't we just ditch it for the moment (ie, not move to trunk/)? Bye, Erik.
