[iolib-devel] crash with the current iolib
by Aycan iRiCAN 05 Jun '07

05 Jun '07

Hi, First I want to thank you for your great effort. I tried to stress the current iolib. Attached is a simple HTTP reply generator. I used sbcl 1.0.5 VM on a 32 bit AMD desktop machine. I used siege with lot's of concurrent connections. Here is the first inspection: This is my stupid test server with current iolib (with a small content size). aycan@zen ~ $ siege -b -c10 -t5S http://localhost:8001/ ** siege 2.61 ** Preparing 10 concurrent users for battle. The server is now under siege... Lifting the server siege.. done. Transactions: 6996 hits Availability: 100.00 % Elapsed time: 4.86 secs Data transferred: 615648 bytes Response time: 0.01 secs Transaction rate: 1439.51 trans/sec Throughput: 126676.54 bytes/sec Concurrency: 9.53 Successful transactions: 6996 Failed transactions: 0 Longest transaction: 4.25 Shortest transaction: 0.00 I got 1490 transactions per second. The performance is great (I got around 500 trans/sec with a threaded version) but when I repeat the test, SBCL crashes silently and eats all my cpu. I don't get any errors or some output. Also the :timeout parameter to add-fd should not be nil by default, if so I got type errors with lengthy content sizes. Here is the same siege parameters applied to *apache-tomcat-6-0-13* (the content size is around 7600 bytes): aycan@zen ~ $ siege -b -c100 -t5S http://localhost:8080/ ** siege 2.61 ** Preparing 100 concurrent users for battle.

[iolib-devel] New releases: iolib-posix-0.5.4 and iolib-0.5.3
by Stelian Ionescu 03 Jun '07

03 Jun '07

I've just made a new round of releases. Changes WRT the previous version are: * NET.SOCKETS: TCP socket options for Linux and FreeBSD have been added, so now you can set options like TCP_MAXSEG and TCP_NODELAY * NET.SOCKETS: calling BIND-ADDRESS on active sockets now works, although probably it is seldom needed * NET.SOCKETS: the function MAKE-SOCKET have been renamed to CREATE-SOCKET, and an implementation of MAKE-SOCKET compatible with Allegro 8 has been added basically you can now do something like this: (make-socket :address-family :internet :type :stream :connect :passive :reuse-address t :local-host host :local-port port) * NET.SOCKETS: it is now possible to specify an active socket's external format in MAKE-SOCKET and setting it through (SETF EXTERNAL-FORMAT-OF) works better; accepted values are: - keywords: either :default or the name of an encoding, :utf-8 or :ascii for instance - lists specifying the encoding and the end-of-line flavour(:unix, :mac or :dos): '(:utf-8 :line-terminator :dos) - EXTERNAL-FORMAT structures, as returned by IOENC:MAKE-EXTERNAL-FORMAT * a modified version of CL-SMTP has been added in package NET.SMTP-CLIENT the system depends on CL-BASE64 and has only one external symbol: the function SEND-EMAIL * NET.SOCKETS: the INVALID-ADDRESS condition has been eliminated, the address conversion functions(like DOTTED-TO-VECTOR, VECTOR-TO-COLON-SEPARATED ...) now signal only TYPE-ERROR or PARSE-ERROR * IO.MULTIPLEX: EVENT-DISPATCH has been improved, and two more functions have been exported: EXIT-EVENT-LOOP and EVENT-BASE-EMPTY-P(which returns T when no events are being monitored by an event base) A special variable *MAXIMUM-EVENT-LOOP-TIMEOUT* has been exported: it serves to limit the poll time of the event loop in case a thread other than the one of the event loop accesses the event base. Defaults to 1 (in seconds) but can also be bound to NIL which means no timeout(or infinity) -- (sign :name "Stelian Ionescu" :aka "fe[nl]ix" :quote "Quidquid latine dictum sit, altum videtur.")

[iolib-devel] iolib fails to compile
by Faré 17 May '07

17 May '07

With the latest iolib, iolib-posix and cffi from darcs, trying to load the fasl for file io-multiplex/utils.lisp fails miserably. Does iolib depend on some non-committed things in iolib-posix? Or on a special branch of cffi? Unknown CFFI type: :TIME.

[iolib-devel] Additions to iolib-posix

[iolib-devel] Liberating cffi-grovel
by Sean 27 Apr '07

27 Apr '07

Hi all, I've noticed that cffi-grovel has (recently?) been superseded (along with the rest of cffi-net) by iolib-grovel. I've been using cffi-grovel for a while now and am My current thoughts are that a) cffi-grovel is a nice descriptive name and b) this is the kind of package that should be asdf-install'able on it's own. Are there any plans for liberating cffi-grovel and making it standalone project? Cheers, Sean. -- ...Please don't assume Lisp is only useful for Animation and Graphics, AI, Bioinformatics, B2B and E-Commerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list.

[iolib-devel] Trivial patch to iolib
