[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

[hunchentoot-devel] Displaying partial output from the handler?
by Andrei Stebakov 01 Apr '07

01 Apr '07

I was wondering if it's possible to create a handler which can output some message to the user browser and then continue with it's own lengthy operation so that a user could see some output? Thank you, Andrew

[hunchentoot-devel] GET-REQUEST-DATA unhappiness with firefox's xforms plugin
by dat 29 Mar '07

29 Mar '07

I've been using hunchentoot with the firefox xforms plugin and recently switched to mod_lisp2 with apache's httpd. xhtml pages seem to work fine. However, when submitting results from an xforms document to hunchentoot under mod_lisp2, the client request is never answered -- when the client request is interrupted, sbcl complains... end of file on #<FLEXI-STREAMS::FLEXI-LATIN-1-IO-STREAM {AD9F809}> [Condition of type END-OF-FILE] The backtrace suggested that GET-REQUEST-DATA is unhappy with the request... 8: (ERROR END-OF-FILE) 9: (READ-LINE #<FLEXI-STREAMS::FLEXI-LATIN-1-IO-STREAM {AD9F809}> T NIL #<unused argument>) 10: (HUNCHENTOOT::GET-REQUEST-DATA) 11: (HUNCHENTOOT::PROCESS-CONNECTION #<HUNCHENTOOT::SERVER {AB55C09}> #<SB-BSD-SOCKETS:INET-SOCKET descriptor 19 {AB87E61}>) If I take mod_lisp out of the picture and just make the request from hunchentoot directly there doesn't seem to be a problem. If I change the code for key/value reading in GET-REQUEST-DATA (headers.lisp) to for value = (read-line *hunchentoot-stream* nil nil) ;;for value = (read-line *hunchentoot-stream* t) things work like a charm (at least, superficially...). Unfortunately, at this point, I'm a little out of my depth... Does hunchentoot throwing an error indicate that the xforms plugin is buggy (maybe leaving an extra blank line somewhere in the http where it shouldn't)? Thanks for any thoughts/suggestions...

[hunchentoot-devel] Using utf-8 strings with with-html macro.
by Victor Kryukov 24 Mar '07

24 Mar '07

Hello list, I'm trying to output some cyrillic letters on the web page like this: (setf *hunchentoot-default-external-format* (flex:make-external-format :utf-8 :eol-style :lf)) (defun main-page () (setf (content-type) "text/html; charset=utf-8") (with-html (:html (:head (:title "Test page")) (:body (:h2 "Main page") (:p "Русский тест") ; Cyrillic letters - "Russian test" )))) but the resulted page is empty. The lisp file itself in utf-8 coding system. Am I missing something? My system is Ubuntu 2.6.17, sbcl 1.0.3.38, hunchentoot 0.7.2 Thanks a lot, Victor Kryukov http://antlook.com

[hunchentoot-devel] Hunchentoot data-transfers seem slow
by Robert Synnott 23 Mar '07

23 Mar '07

Hi, I've messed around with Hunchentoot before a good bit, but this week launched my first real site with a moderate number of visitors (http://twitterbuzz.com - hunchentoot/mod_proxy). Now, the site seemed slightly sluggish, but at first I was inclined to blame this on the page generation. Looking closer, though, the page generation happens practically instantly, and the slowness seems to turn up in sending the data back to the user. Playing with apache-bench, I found that transfer speed seems to cap out at about 250KB/s, even when just sending a huge static page (a largish ebook off Gutenburg). For the moment, I've shifted the site to using tbnl (with mod_lisp), and things seem to run faster; ab can now download the ebook at about 30MB/s, and page loading on the site itself seems snappier. However, I'm aware that tbnl is deprecated. Is this something silly I'm doing, or an inherent limitation of hunchentoot/flexi-streams? Also, are there any major issues with tbnl I should be aware of? I'm particularly concerned about this because I'm currently moving a far larger site with lots of users to lisp, and I suspect that the speed problem would be a real issue with it. Rob

[hunchentoot-devel] Form Processing & responding to events
by Bill Tate 16 Mar '07

16 Mar '07

Lisp and Hunchentoot newbie here. I haven't been able to find an answer to the following question by searching the existing archives. I have a very substantial application written in PHP and MYSQL and would love to convert it over to Lisp using Hunchentoot and CL-SQL. My question is that I can't find anything to indicate how I can capture something like an onClick or an onLoad event using the keyword notation provided by Hunchentoot. I noticed from the test demo for the easy handler example that hitting the enter key while on a text box will cause the form to be submitted but I can't see where in the code this is explicitly called for. Any clarification or assistance would be most appreciated.

[hunchentoot-devel] log-message and *log-lisp-warnings-p*
by Peter Denno 15 Mar '07

15 Mar '07

Hi, Is there a reason why these two calls to log-message in server.lisp are not wrapped in (when *log-lisp-warnings-p*) and (when *log-lisp-errors-p*) like they are in process-request? (defun process-connection (server handle) "This...occurs." (handler-bind ((error ;; abort if there's an error which isn't caught inside (lambda (cond) (log-message *lisp-errors-log-level* "Error while processing connection: ~A" cond) (return-from process-connection))) (warning ;; log all warnings which aren't caught inside (lambda (cond) (log-message *lisp-warnings-log-level* "Warning while processing connection: ~A" cond)))) Hunchentoot is wonderful software, BTW. I use it here: http://syseng.nist.gov/se-interop and here http://syseng.nist.gov/moss -- Best regards, - Peter

[hunchentoot-devel] Showing progress to the user
by Andrei Stebakov 09 Mar '07

09 Mar '07

I'd like to know if there is some functionality in hunchentoot that would allow me to show the progress page to the user. Let's say a user click on a link handle by hunchentoot hander method which takes a lot of time to process. How can I show a page that says "Please, wait" which will redirect to the actual data view of the handler? Here I can think of only "<meta http-equiv='refresh' content='0;" but maybe there is something supported by the framework? Sorry if my question is not totally related to hunchentoot. Thank you, Andrew

[hunchentoot-devel] Additional encoding support(Was: New release 0.7.2)

Edi Weitz wrote: > The new release should fix that. > > Thanks for the bug report, You're welcome. My thanks for the fix. * * * I may need to write some additional encoding support to Hunchentoot, for my client. For example, euc-jp(LW supports this), Big5(LW does not support this), etc. Would you tell me any of guidelines, hints, tips, files to read, etc? I'll submit the final result to you, if it has a quality. Regards Jong-won

[hunchentoot-devel] Errors with test pages
by Jong-won Choi 09 Mar '07

09 Mar '07

Hello I have errors with Hunchentoot's test pages - 'GET parameter handling with UTF-8 charset' and 'POST parameter handling with UTF-8 charset' get errors. I thought (setf (content-type) ...) in parameter-test function does this utf-8 magic, but it seems it does not work and raise an error later. I'm trying standalone Hunchentoot - I'm an old TBNL user. TBNL (with lighttpd + fastcgi) test pages work fine. My configurations is: Ubuntu 6.06.1 LTS LW 4.4.6 Professional chunga-0.2.4 cl-base64-3.3.2 cl-ppcre-1.2.19 cl-who-0.6.3 flexi-streams-0.10.3 hunchentoot-0.6.2 md5-1.8.5 rfc2388 trivial-gray-streams-2006-09-16 url-rewrite-0.1.1 Anyone can confirm the test pages are working? Fix for this problem? Cheers Jong-won Choi

[hunchentoot-devel] standalone server lw 5.0
by Phlex 07 Mar '07

07 Mar '07

Hello, I'm a user of tbnl and finally decided to make the switch to hunchentoot. When trying what's below, i get an empty page in the web browser. Here is what i'm trying : (defparameter *web-server* (start-server :port 3000)) (defmacro with-html (&body body) `(with-html-output-to-string (*standard-output* nil :prologue t) ,@body)) (defparameter *original-standard-output* *standard-output*) (defmethod dispatch-request :around (dispatch-table) (pprint "coucou1" *original-standard-output*) (let ((result (call-next-method))) (pprint result *original-standard-output*) (pprint "coucou2" *original-standard-output*) result)) (defun bleh () (with-html (:html (:head (:title "easy demo")) (:body "That's bleh !")))) (setq *dispatch-table* (list (create-prefix-dispatcher "/" #'bleh))) Here is what i see on my standard ouput when i try to visit the web site at this address : http://localhost:3000/ "coucou1" "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Strict//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\"><html><head><title>easy demo</title></head><body>That's bleh !</body></html>" "coucou2" So it seems that everything goes well ... i'm at a loss wrt what i should do now to actually see the web page ... Thanks in advance for any pointer. My config : lispworks 5.0, win32, firefox, standalone hunchentoot (no mod_lisp, no apache) Sacha

If you only need it for testing, why bother with "free"? You can for example use the trial version of LispWorks to test your web server.

Thanks. I won't have enough time to look at this before the second half of the week, though. Which version of SBCL did you use? > In order to do so I had to optinally disable ssl cause I couldn't > find appropriate ssl library to use. This one works for LispWorks: http://www.slproweb.com/products/Win32OpenSSL.html > and applied a patch from William Bland to work without threads. Hmm. I remember that one. I don't think you really want to have a single-threaded web server for anything but testing. Thanks, Edi.
