[usocket-devel] BUG: dangling references to split-sequence package
by Andy Chambers 13 Jan '10

13 Jan '10

There is a dangling reference to split-sequence but split-sequence itself is no longer marked as a dependency in the defsystem spec. This means that usocket cannot currently be loaded using asdf unless split-sequence has already been loaded by some other system. The attached patch just replaces calls to split-sequence:split-sequence with corresponding calls to cl-utilities:split-sequence. Also I think a few of the tests might need to be rewritten. Both before and after applying this patch, 6 out of 15 tests fail for me. Regards, Andy Chambers (format t "type: ~a version: ~a" (lisp-implementation-type) (lisp-implementation-version)) type: SBCL version: 1.0.18.debian (usocket-test:run-usocket-tests) Doing 15 pending tests of 15 tests total.

[usocket-devel] cl-utilities dependency
by Attila Lendvai 12 Jan '10

12 Jan '10

hi, any reason not depending on alexandria instead? cl-utilities with its split-sequence is a headache: it has a s-s but not a .asd file, so i can not drop the repo-less s-s in favor of cl-utilities. but if i keep them both, then it brainlessly redefines, which stops the build... -- attila

[usocket-devel] patches for usocket mcl backend and tests
by james anderson 06 Jan '10

06 Jan '10

good evening; please find attached patches for the mcl back-end and the tests. the system names follow from the local conventions for asdf systems, but the other changes should be generally useful. given these changes mcl 5.2 passes all 15. i cross-checked with openmcl ("Version 1.3-r11936 (DarwinPPC32)") which succeded as well. * test/test-usocket.lisp : added timeout arguments to the no-connect tests, as both mcl and openmcl otherwise hang : added mcl to the caught conditions for failure tests : wrapped typep tests to force t/nil : corrected #\newline to be #\linefeed : added a +local-ip+ variable * test/usocket-test.asd : changed dependencies to be fully qualified * usocket.asd : modified dependency to use cl-utilities (by fully qualified system name) * backend/mcl.lisp : handle-condition : corrected to formulate the error argument as required for the respective error class : socket-connect : reinstated with-mapped-conditions : socket-listen : reinstated with-mapped-conditions : socket-accept : reinstated with-mapped-conditions : %*-wait operators : added no-op versions

[usocket-devel] r507 : open-mcl : socket-connect scales the timeout value incorrectly
by james anderson 03 Jan '10

good evening; in the openmcl backend, socket-connect[1] converts the timeout value to internal runtime units, but (at least for a tcp connection) the respective ccl operator[2] intends to convert from seconds to milliseconds ---- [1] http://trac.common-lisp.net/usocket/browser/usocket/trunk/backend/ openmcl.lisp?rev=499#L89 [2] http://trac.clozure.com/ccl/browser/trunk/source/level-1/l1- sockets.lisp#L774 socket-connect -> make-socket -> make-ip-socket -> make-tcp-socket -> make-tcp-stream-socket

Or is it more like LISTEN in Common Lisp? It's more like LISTEN, but it can listen on multiple connections at the same time. So, do you have any idea on how to implement it? And please notice: the WAIT-FOR-INPUT-INTERNAL should wait on "socket" but "stream", because that's what USOCKET API defined. And, more important, having that function wait on "sockets" could make the function also fit into usage of UDP sockets which doesn't have correspond stream objects. > > One important detail is that the MCL OpenTransport module establishes connections for passive streams on a port in a FIFO manner.

Hi, Terje USOCKET Support on MCL (at least RMCL) is already in my plan. There're some higher priority tasks on USOCKET side, like full support of SBCL and ECL on win32, etc., and every USOCKET maintainer is busy working on other projects (ABCL, BKNR, ...). So if MCL users can wait, I promise the MCL backend of USOCKET will be coming in *no later than a month*, or if someone here is interested in helping us, patches are most welcome. --binghe > Does somebody know of an MCL backend for the USOCKET portable tcp/ip > socket interface? > > http://common-lisp.net/project/usocket/ > > -- Terje Norderhaug > terje(a)in-progress.com > > > > > _______________________________________________ > info-mcl mailing list > info-mcl(a)clozure.com > http://clozure.com/mailman/listinfo/info-mcl

[usocket-devel] ECL and MSVC
by Seth Burleigh 28 Dec '09

So I searched for it, it looks like you just #+(and :ecl :msvc) #include "time.h" For a msvc build, I think, instead of just including "sys/time.h" Though im not sure, it builds, but I haven't tried any tests.
