[usocket-devel] Wait-for-input/socket-accept for sbcl/win32
by Kalyanov Dmitry 19 Sep '10

19 Sep '10

Definition of USOCKET class has the comment the %READY-P slot is reset by SOCKET-ACCEPT function. But right now SOCKET-ACCEPT does not reset it, hence WAIT-FOR-INPUT will not actuall wait after the first it time it notices the readiness. Also, SB-BSD-SOCKETS:SOCKET-ACCEPT may return NIL (if accept call returned EWOULDBLOCK, for example), and USOCKET:SOCKET-ACCEPT will try to use it. Attached is a patch that fixes these two issues.

Re: [usocket-devel] [usocket-cvs] r553 - in usocket/trunk: . backend vendor

Hi Chun, I think the JDI stuff I added way back when, isn't needed anymore. You could try removing it. Before, it wasn't always possible to dynamically determine retrieve a method from a JavaObject. Now, since it has an IntendedClass slot, the information that JDI was trying to capture, has been added to the base JavaObject class. If you want, I can help to phase out JDI. With kind regards, Erik.

[usocket-devel] USOCKET Web Site updated and ...
by Chun Tian (binghe) 15 Sep '10

15 Sep '10

Hi, Erik Today I committed updates for USOCKET Web site [1], with more API documents [2] and information about new supported platform (MCL). I think we should release 0.5.0 as soon as possible, since we have last stable release (0.4.1) at Dec 27, 2008. It's one and a half years ago ... The brief release notes could be this one: * New supported platform: Macintosh Common Lisp (5.0 and up, plus RMCL) * Support for UDP (datagram-usocket) for all supported platform except MCL. * Add WAIT-FOR-INPUT support for SBCL and ECL on win32. * Simple TCP and UDP server API: SOCKET-SERVER * Lots of bug fixed since 0.4.1 I consider, there're obviously new bugs in those new features, but these potential bugs won't influence exist features which 0.4.x already have. So the release shouldn't break any package depends on USOCKET 0.4.x or 0.3.x, it's quite safe for people who don't need new features in USOCKET, and give people who need them a stable reference point. It's worth to release first, and fix things up later. Let me know your opinion. Regards, Chun Tian (binghe) [1] http://common-lisp.net/project/usocket [2] http://common-lisp.net/project/usocket/api-docs.shtml

[usocket-devel] UDP support for ABCL added
by Chun Tian (binghe) 14 Sep '10

14 Sep '10

Hi, USOCKET users Recently I rewrote all ABCL supporting code for USOCKET, now UDP and GET-HOST-BY-NAME are added for ABCL. There're still some issues in server-side UDP support, but client UDP sockets are ready to use. Now it's time to think about our next release (0.5.0), I think. --binghe
