[tbnl-devel] tbnl / sbcl 0.8.21
by Keith Irwin 06 Apr '05

06 Apr '05

Folks-- I believe Edi forwarded a message I'd written about some sort of byte-related encoding problems (or decoding) with regard to SBCL. The problem occurs when I want to serve up an image file as part of, say, a background for a web site. Does anyone want to focus my attention on any particular files, or areas to envistigate, or should I just leave well enough alone because you all are about ready to update the code? Edi's comment: > One solution might be to check if SBCL has some kind of default > external format which can be used to overwrite the UTF-8 format. I > don't use SBCL myself but I seem to remember that this might depend on > the value of some environment variable when the image is started. > Maybe someone else here knows the details. > Another option would be to treat SBCL like LW and AllegroCL in case it > also has bivalent streams. Since I'm not a developer of TBNL nor do I intend to be, I'm not sure what the above means. Is the problem that TBNL is trying to read a binary file into, uh, characters, or something? Anyway, I'll see if I can't come up with a hack and then drop it here in case it'll help an expert get a real fix in quicker. Thanks, Keith

I don't use SBCL myself but I seem to remember that this might depend on the value of some environment variable when the image is started. Maybe someone else here knows the details. Another option would be to treat SBCL like LW and AllegroCL in case it also has bivalent streams. HTH, Edi.

Argh! That happens if you think you can type faster than slime-complete-symbol... :( I've uploaded a corrected version (0.5.4). Thanks and sorry for the noise, Edi.

ASDF is not used to "start up" or "fire up" packages but to load libraries. You might want to look at the ASDF documentation or at my ASDF-INSTALL tutorial. If you just want to serve pages other than the ones from the test website with TBNL you don't necessarily need a new package and you don't need ASDF either. Instead, you should read the documentation about handlers and dispatchers: <http://weitz.de/tbnl/#handlers> You can change these values while TBNL is already running. Cheers, Edi.

[tbnl-devel] A Small Problem with TBNL Stand-alone
by Bob Hutchison 02 Apr '05

02 Apr '05

Hi, I'm back from vacation and am now integrating 0.5.2 into my main code base. This so I can make use of the Araneida and standalone TBNL. It didn't work. I got it to work by changing how *use-modlisp-headers* is used. I've attached a patch. I think you must have changed how I was using it while cleaning up the patch I sent originally.

[tbnl-devel] basic package question
by Jason Wang 02 Apr '05

hi, i have read through the documentation for both TBNL and CL-WHO, i have created a page based on what i read.. but i found out i can't figure out how to test the page.. i can see the test page by doing (asdf:oos 'asdf:load-op :tbnl-test), how do i change package from :tbnl-test to something else? what code do i need to add? i have tried just adding a folder and declare (in-package #:tbnl-test2), that didn't work out too well.. what do i need to do in order to start test2? thanks alot :D ps. if this is on the documentation, please excuse my ignorance.. i indeed have read all of it and didn't find any answers to it.. -- www.programer.name - my own personal blog : )

[tbnl-devel] That Memory Consumption Problem Unique to OS/X (Again)
by Bob Hutchison 01 Apr '05

01 Apr '05

Hi, I've been looking into that unbound memory consumption situation when directly connecting to TBNL (that doesn't happen when going through mod_lisp or Araneida and only seems to happen on OS/X). I put some debugging statements into KMRCL and have (finally) noticed something that was blindingly obvious before. There is a KMRCL function lw-worker in listener.lisp that is called for every request made to TBNL directly. It is called only once (or, at least, a very few times) if TBNL is invoked indirectly (i.e. via mod_lisp or Araneida). The call to this function is through a lambda that is defined in make-socket-server and passed to comm:start-up-server. I am assuming at this point that this has something to do with the problem. Now, I don't really understand what is going on here. I will continue to look into this, but if anyone happens to already know what is going on here I'd love to hear about it. Cheers, Bob

[tbnl-devel] problem with the example
by Sergio Garcia 19 Mar '05

19 Mar '05

Hello; I have just installed TBNL on debian sarge, using SBCL 0.8.19.39. The Kevin Rosemberg packages were installed using apt-get, and TBNL and other dependencies were installed using asdf-install The example seems to work fine, except for the "session" page. The page is displayed fine initially, but when I try to submit a change it displays the "An error has occured" message. (The upload files example works fine). This error occurs using both mod_lisp and 'stand-alone' tbnl. When using mod_lisp, thefollwing messaged is logged in the apache error log: [Fri Mar 18 20:28:55 2005] [error] (20014)Error string not specified yet: [TBNL] The assertion (NOT [Fri Mar 18 20:28:55 2005] [error] (20014)Error string not specified yet: [TBNL] (EQL SB-THREAD::NEW-VALUE [Fri Mar 18 20:28:55 2005] [error] (20014)Error string not specified yet: [TBNL] (SB-THREAD:MUTEX-VALUE SB-THREAD::LOCK))) failed. Any hint about why this error appears? Is there anything I can do to get a more detailed description of the error in the lisp repl or in the browser? Thanks, Sergio
