I just re-ran hunchentoot-test.

[hunchentoot-devel] Having trouble with create-folder-dispatcher-and-handler
by Jeff Cunningham 17 Dec '07

17 Dec '07

I haven't used this handler for awhile, but I do recall it worked the last time I did. Now, when I set up a simple test case it fails, generating an Internal Server Error (500) with this error message in the log: [error] [Hunchentoot] The value NIL is not of type (MOD 536870911) I isolated it as far as the enough-url function, where it seems that the mismatch is returning NIL and the subseq doesn't like it. My test case is: (create-folder-dispatcher-and-handler "/test/" #p"/home/hunchentoot/test/" "text/plain") Both folders exist and are world readable. I am running SBCL 1.0.12. I tried checking what the arguments are to enough-url when it fails - they are: "url=/test/ url-prefix=/test/ which, of course, explains the NIL and the failure of the subseq. I don't understand how this handler is supposed to work, which it makes it difficult for me to troubleshoot further. Any idea why this doesn't work? --Jeff

Hi Edi, Debating whether to mention this or not... Have you noticed the text that shows up when you search for Hunchentoot in google: "HUNCHENTOOT - The Common Lisp web server formerly known as TBNL Web server coded in Common Lisp; supports HTTP/1.1 chunking, persistent connections (keep-alive), and SSL; works only with LispWorks." The 'works only with LispWorks' bit is maybe something you don't want there?

[hunchentoot-devel] how to diagnose output problem?
by Jim Prewett 07 Dec '07

07 Dec '07

Hello, I'm new to Hunchentoot. :) I'm working on an app that uses the Demo Allegro Lisp, the AGraph package, and Hunchentoot for the front-end. When I run on MacOS, everything seems great! When I run on Linux, things are not so good. I get *NO* output from Hunchentoot when I put certain records into the database. I don't have any idea if this is a Hunchentoot bug, a Agraph/Franz bug, or a bug in my understanding :) I don't see any errors at the REPL - I've not hit the limitations of the demo ACL. The function I use, when I put (warn ...) statements in, clearly finds all of the records I've requested and thinks its done all of its work (it believes its output the entire webpage), but I get no output :P Can anyone give me suggestions on how to tell /where/ I'm having the problem? I got hunchentoot and friends from asdf-install this morning on both systems (Mac and Linux). I'm running the latest ACL/AGraph. I've set *SHOW-LISP-BACKTRACES-P* and *SHOW-LISP-ERRORS-P* to t and don't see any errors. Here is a transcript of using telnet to request the page: # telnet localhost 80 Trying 127.0.0.1...

I have to admit that this is the first time I've heard of this recommendation. A quick test with the vastly popular PHP shows that they don't implement it either: <? print_r($_GET); ?> Try these: http://zappa.agharta.de/test.html?foo=bar&baz=quux http://zappa.agharta.de/test.html?foo=bar;baz=quux So, to everyone on the list - what's your experience with semicolons as query string separators?

[hunchentoot-devel] Hunchentoot on abcl?

Hi-- I'm trying to get hunchentoot running on abcl, but it is balking at cffi. Does Hunchentoot use CFFI even when SSL is disabled? Should CFFI be compiled when :hunchentoot-no-ssl is on features?

[hunchentoot-devel] printing to *standard-output* in a multithreaded environment
by Andrei Stebakov 24 Nov '07

24 Nov '07

I wonder is it save to have a macro like this: (defmacro with-html (&body body) `(with-html-output-to-string (*standard-output* nil :prologue t) ,@body)) with SBCL which is multithreaded. What happens when multiple users connect to the server and the requests are served using the macro above. I mean how do multiple threads share the *standard-output* in this case? Or should I create a new stream per request? Thank you, Andrew

[hunchentoot-devel] Workaround for OpenMCL bug in ENOUGH-NAMESTRING
by Hans Hübner 15 Nov '07

15 Nov '07

Hi, OpenMCL has a bug in ENOUGH-NAMESTRING that makes Hunchentoot fail when the "/" prefix is exported from the file system using CREATE-FOLDER-DISPATCHER-AND-HANDLER. ENOUGH-NAMESTRING fails to work for URI paths having more than one component. As URI strings are not path names, I find using ENOUGH-NAMESTRING being a little fishy here anyway and I'd propose the following patch, courtesy of Kilian Sprotte: Index: misc.lisp =================================================================== --- misc.lisp (revision 2274) +++ misc.lisp (working copy) @@ -177,6 +177,11 @@ (lambda () (handle-static-file path content-type))))) +(defun enough-url (url url-prefix) + "Return the relative portion of URL relative to URL-PREFIX, similar +to what enough-pathname does for path names." + (subseq url (mismatch url url-prefix))) + (defun create-folder-dispatcher-and-handler (uri-prefix base-path &optional con tent-type) "Creates and returns a dispatch function which will dispatch to a handler function which emits the file relative to BASE-PATH that is @@ -193,8 +198,8 @@ (error "~S is supposed to denote a directory." base-path)) (flet ((handler () (let* ((script-name (url-decode (script-name))) - (script-path (enough-namestring (regex-replace-all "\\\\" scr ipt-name "/") - uri-prefix)) + (script-path (enough-url (regex-replace-all "\\\\" script-nam e "/") + uri-prefix)) (script-path-directory (pathname-directory script-path))) (unless (or (stringp script-path-directory) (null script-path-directory)
