[hunchentoot-devel] Processing an error outside the Hunchentoot code
by Andrei Stebakov 08 Apr '07

08 Apr '07

What's the best to add my own error handler? I see there is some processing based on *SHOW-LISP-ERRORS-P* *SHOW-LISP-BACKTRACES-P* inside process-request function, but it doesn't allow to add a user handler of the error (or I just didn't find it). Let's say I don't want a user to see the error (only some nice reassuring message :)) and I want to be notified by an email with the backtrace. Should I go and modify the body of the process-request function (which I'll need to merge with every new release of HT) or is there a way to add my own handler outside of the Hunchentoot code? Thank you, Andrew

[hunchentoot-devel] Different speed loading images from static apache and hunchentoot handler
by Andrei Stebakov 06 Apr '07

06 Apr '07

I got a folder on my linux box that contains about 240 images of font preview generated from cl-gd (Thanks, Edi!). When I show them from static apache handler it takes approximately 30 seconds. Same thing from hunchentoot static handler (create-folder-dispatcher-and-handler) takes about 50 seconds. I understand it's not a big deal, but still I'd like to know what might get in the way. I use hunchentoot behind mod-proxy. Here are links (first is static apache, second is hunchentoot): http://www.greenpixeldesign.com/fonts.html http://www.greenpixeldesign.com/cphandler/fonts.html Thank you, Andrew

There were significant changes between 0.8.0 and 0.11.1 and it is likely that you're the first one to use the new version on AllegroCL, especially on a 64-bit version (if that matters, don't know). There's also a chance that some of my recent Hunchentoot changes which I hastily submitted in the wake of my ILC preparations broke something which results in sockets being closed although they shouldn't. That's why I'm sending a copy of this to tbnl-devel as well. > How can I help debug this more ? Try to get a detailed backtrace of the error. You might want to check what the previous page (before the socket was closed) was supposed to send (return code, size of content, headers, transfer encoding). Also, delete the FASL files from FLEXI-STREAMS and Hunchentoot, recompile, and check all the warnings you might get during compilation. Thanks, Edi.

The HCL:MARK-AND-SWEEP function is only available on 32 bit LispWorks. A small patch is below to allow hunchentoot to run on 64 bit versions of LispWorks.
