[hunchentoot-devel] Hunchentoot not working on OpenMCL 1.1pre
by Tiarnan O'Corrain 03 Nov '07

03 Nov '07

Hi-- I've just installed a brand new OpenMCL pre-prelease ("Version 1.1-pre-070512 (DarwinPPC32)") and am getting the following error in the browser when accessing the default hunchentoot page: NIL Unknown http return code: 200 A backtrace from SLIME is given below. Originally I thought the problem was due to a reference in port-mcl.lisp to ccl::make-timer-request: I installed acl-compat, which provides this, with no change in outcome. Any pointers to fruitful areas of investigation would be appreciated. regards Tiarnán Stream #<BASIC-FILE-BINARY-OUTPUT-STREAM ("/tmp/hunchentoot.log"/24 ISO-8859-1) #x93BC97E> is private to #<PROCESS hunchentoot-worker-1(48) [Exhausted] #x93BBC1E> [Condition of type SIMPLE-ERROR] Restarts: 0: [ABORT-BREAK] Reset this process 1: [ABORT] Kill this process Backtrace: 0: (#<Anonymous Function #x85C7C2E> 0 20) 1: (SWANK:BACKTRACE 1 41) 2: (CCL::CALL-CHECK-REGS 'SWANK:BACKTRACE) 3: (#<Anonymous Function #x86434AE> '(SWANK:BACKTRACE 1 41) 44 'NIL) 4: (#<Anonymous Function #x85687F6> #<Compiled-function SWANK:SWANK-DEBUGGER-HOOK #x863C6A6> #<COMPILED-LEXICAL-CLOSURE #x93EE3CE>) 5: (FUNCALL 'SWANK::EVAL-FOR-EMACS) 6: (SWANK::SLDB-LOOP '(70 T 10 T NIL 10 T #S(CCL::PPRINT-DISPATCH-TABLE :CONSES-WITH-CARS #<HASH-TABLE :TEST EQ size 60/60 #x85DEBB6> :STRUCTURES NIL :OTHERS (#<CCL::ENTRY #x846914E> #)) NIL T ...)) 7: (SWANK::CALL-WITH-BINDINGS '((*PRINT-PRETTY* .

[hunchentoot-devel] host/port question

I'm not sure what "the right thing" here is, but it struck me as odd that redirect didn't include a port argument, so I made the following changes to redirect: --- hunchentoot-0.9.0/misc.lisp 2007-03-30 14:01:27.000000000 -0700 +++ ../hunchentoot-0.9.0/misc.lisp 2007-04-27 22:45:00.000000000 -0700 @@ -229,6 +229,7 @@ (add-session-id (not (or host-provided-p (starts-with- scheme-p target) (cookie-in *session-cookie-name*)))) + port permanently) "Redirects the browser to TARGET which should be a string.

[hunchentoot-devel] Custom types for easy handler.
by Timothy Schaeffer 01 Jun '07

01 Jun '07

Hello all, I propose that the types for easy-handlers be extensible by the users. I have pieces of markup which are used throughout our site which collect information from several fields into a class (in our case tied to a database with clsql). The names of the fields are related, but diffierent from the lists, arrays and hashes of the easy-handlers, Dates and addresses are two good examples, but there are others. I would like to be able to teach the easy handler to collect these for me and pass them as parameters. This cannot be done with functions as the :parameter-type because the functions passed as :parameter-type do not take the parameter name. There are two ways I think this could be done: - The easier way: add a :paramater-reader arg to the parameter description, and if passed use it in lieu of the ((post|get)-)?parameter functions in compute-parameter. The following might do it (untested): (defun compute-parameter (parameter-name parameter-type request-type &optional parameter-reader) ; <===== "Computes and returns the parameter\(s) called PARAMETER-NAME and converts it/them according to the value of PARAMETER-TYPE. REQUEST-TYPE is one of :GET, :POST, or :BOTH." (when (member parameter-type '(list array hash-table)) (setq parameter-type (list parameter-type 'string))) (let ((parameter-reader (or parameter-reader ; <==== (ecase request-type (:get #'get-parameter) (:post #'post-parameter) (:both #'parameter))) ) (parameters (and (listp parameter-type) (case request-type (:get (get-parameters)) (:post (post-parameters)) (:both (append (get-parameters) (post-parameters))))))) (cond ((atom parameter-type) (compute-simple-parameter parameter-name parameter-type parameter-reader)) ((and (null (cddr parameter-type)) (eq (first parameter-type) 'list)) (compute-list-parameter parameter-name (second parameter-type) parameters)) ((and (null (cddr parameter-type)) (eq (first parameter-type) 'array)) (compute-array-parameter parameter-name (second parameter-type) parameters)) ((and (null (cddddr parameter-type)) (eq (first parameter-type) 'hash-table)) (compute-hash-table-parameter parameter-name (second parameter-type) parameters (or (third parameter-type) 'string) (or (fourth parameter-type) 'equal))) (t (error "Don't know what to do with parameter type ~S." parameter-type))))) (defun make-defun-parameter (description default-parameter-type default-request-type) "Creates a keyword parameter to be used by DEFINE-EASY-HANDLER. DESCRIPTION is one of the elements of DEFINE-EASY-HANDLER's LAMBDA-LIST and DEFAULT-PARAMETER-TYPE and DEFAULT-REQUEST-TYPE are the global default values." (when (atom description) (setq description (list description))) (destructuring-bind (parameter-name &key (real-name (compute-real-name parameter-name)) parameter-type init-form request-type parameter-reader ) ; <==== description `(,parameter-name (or (and (boundp '*request*) (compute-parameter ,real-name ,(or parameter-type default-parameter-type) ,(or request-type default-request-type))) ,init-form)))) (This just occurred to me: request-type could be a function, with an obvious change to the ecase. This is a little more confusing but consistent with what parameter-type does---so it has the force of precedent---and requires a smaller change to the code.). - The extensive way: Change the cond in compute-parameter to a switch via a hash table, whose values are the conversion handlers (or a cons with reader and converter). It may need two hash tables: one for simple type names (type is a symbol) and one for aggregates, (type is a cons, and switch on the first element). Create a macro, define-easy-type, or something, to populate the tables, and use it within easy-handlers.lisp to populate it with those which are now hardcoded in the cond and case switches. Users can then use the macro to define their own types. - Another way: like above, but use methods instead of hash tables. This seems possible, but I'd have to think some more about it. BTW: why the checks for null CDDRs and CDDDDRs in compute-parameter? Is this just nice, or are they essential? If your interested in the second, I will work something up and send in a patch. I do not think it would break any existing code which did not peak too far into the easy-handlers stuff. Let me know what you think. Tim S P.S.: Hunchentoot is a pleasure to work with!

Yes, it looks so. AUX-REQUEST-VALUE is meant so you can /store/ arbitrary values associated with the request and later retrieve them. I have no idea what REST-PUT-PARAMETER is supposed to do or what a "PUT parameter" is. > have u got any idea for this problem ? I don't understand the problem... Did you look at CL-WEBDAV to see how it handles PUT requests as I told you? Cheers, Edi.

[hunchentoot-devel] gzip-encoding
by Mac Chan 28 May '07

28 May '07

With this web 2.0 thing, nowadays it's not uncommon to have javascript library weighting over 500k (with extreme case like dojo which adds up to several megabytes). If you google a bit you'll find that this doesn't concern the toolkit authors because they'll say that if you minimize (eliminate whitespaces) the javascript file and turn on gzip encoding it's a non-issue. It was a low-hanging fruit to add gzip-encoding to hunchentoot since the hard work has already been done by Edi's (flexi-stream), Zach (Salza 1) and Sean Ross (gzip-stream 2). In fact it was only a few lines of changes. Using the network monitor in FireBug , my initial testing (with a 790 KB javascript file) shows that the response time is slower with gzip turned on (I'm guessing that it might be related to flexi-stream.) 262 KB 828ms 875ms 735ms 703ms 719ms 593ms 734ms 790 KB 625ms 359ms 672ms 328ms 610ms 641ms 594ms Since I'm testing with the loopback interface, there's virtually no network overhead. So I launch another firefox in vmware and limit the download rate of the network interface to 150k (the most common DSL speed offered in the states) 262 KB 1.72s 1.72s 1.64s 1.79s 790 KB 5.16s 5.21s 5.11s 5.21s Now we're talking. And we can't ignore the 56k line users, can't we? 262 KB 8.39s 5.07s 4.97s 5.07s 790 KB 15.36s … point taken, I don't want to repeat this :-) So now, the questions remain: Should we add this to hunchentoot or make it an extension module? (this will introduce two new dependencies to hunchentoot) If we add this to hunchentoot, should we add a flag to turn on/off gzip encoding? (probably yes) And again, since there's flexi-stream overhead (my guess), should we add a flag to control what content-type we should disable gzip encoding? (probably wasting cpu cycle to gzip jpeg, mp3 and png, etc). Suggestions? -- Mac 1: http://www.cliki.net/Salza 2: http://common-lisp.net/project/gzip-stream/ (defun handle-static-file (path &optional content-type) "A function which acts like a Hunchentoot handler for the file denoted by PATH.

[hunchentoot-devel] Hunchentoot and OpenMCL
by Lennart Staflin 26 May '07

26 May '07

Hi, I have been using OpenMCL and portable aserve. I ran into some trouble with character encoding, and after looking at the code decided that it would be difficult to fix. I am now considering alternatives. I read somewhere that Hunchentoot runs on OpenMCL so I'm going to try it out. Any experience with running Hunchentoot on OpenMCL, specially the bleeding edge OpenMCL? Any experience converting a project from aserve to Hunchentoot? Also I ran into a compile problem: ;Compiler warnings : ; Undefined function CCL::DEQUEUE-TIMER-REQUEST, in INVOKE-WITH-TIMEOUT. ; Undefined function CCL::ENQUEUE-TIMER-REQUEST, in INVOKE-WITH-TIMEOUT. ; Undefined function CCL::MAKE-TIMER-REQUEST, in INVOKE-WITH-TIMEOUT. from port-mcl.lisp: (defun invoke-with-timeout (seconds bodyfn timeoutfn) "Executes the function \(with no arguments) BODY-FN and returns its results but stops execution after DURATION seconds and then instead calls TIMEOUT-FN and returns its values." ;; from Portable AllegroServe (block timeout (let* ((timer (ccl::make-timer-request seconds #'(lambda () (return-from timeout (funcall timeoutfn)))))) (ccl::enqueue-timer-request timer) (unwind-protect (funcall bodyfn) (ccl::dequeue-timer-request timer))))) Probably the timer functions have been removed in some of the later versions of OpenMCL. Unless someone has a fix already I will dig into this. -- //Lennart Staflin

There are indeed a lot of template libraries including CL-EMB, Edi's own HTML-TEMPLATE, etc. But these libraries are obstinate in that they require you to construct and pass the `environment' variable in order to generate the dynamic content. Secondly, I found that the @if @else template extensions/add-ons are often too limited in expressive power. You are programming lisp in the backend, but all of a sudden you need to drop to a very dumb language when you need to deal with the template code, which is kind of frustrating. John Wiseman's code is very close to what I need, but it is designed to work with Franz's allegoserver. So I port it to work with my preferred web server (hunchentoot) instead. * So should I use this for all my dynamic content generation? No. Absolutely not. If you take a look at the very simple test.lsp, it screams like spaghetti code! In the ideal world, if the graphics designer can deliver properly formatted html in cl-who sexp, I'm all set. But that's not gonna happen. So for pages that I have total control, I prefer to write it using sexp. However, there are times where the designer need to frequently update a messy html template and I cannot afford to sync up with it given the time constraint, using lsp is a good compromise. * Any tips & tricks? Lisp is very hard to write (and even harder to read) without a good editor (like emacs) to help indenting your code and provide structured editing. So unlike other dumber languages (php, perl...), intermixed lisp code with content is extremely hard to maintain and read. In this regard, I would recommend you to use Franz's if-star package ( http://www.franz.com/~jkf/ifstar.txt ) in your template file because it helps you to match the open and close parenthesis for if-then-else conditional expression. Also, unlike other dumber languages where if you have a syntax error in the template file, the compiler can point you to the exact line where it occurs. With lsp, the line number is lost when we use the built-in lisp reader to read the form. However you can use `show-lsp-form' in the REPL to examine the code when you encounter an error.

[hunchentoot-devel] (session-cookie-value) should be exported?
by Slava Akhmechet 25 May '07

25 May '07

I'm writing code to rewrite URLs in JavaScript to support AJAX requests for clients that have cookies disabled. It appears that the right thing to send would be the value returned by (session-cookie-value), not the value returned by the exported (session-string). Should 'session-cookie-value' be exported from the 'hunchentoot' package? -- Regards, Slava Akhmechet.

[hunchentoot-devel] Uploaded files are sometimes incomplete
by Viktor Leis 24 May '07

24 May '07

Hi, when using Hunchentoot with SBCL on debian behind mod_lisp and Apache 1 for video file uploading, the uploads randomly fail (the file is incomplete). Warning on the server: WARNING: 28369838 octets of stray data after form-data sent by client. This happens most of the time if the server is on the same machine as the uploading browser, less often if the server is on a different machine in the LAN and only sometimes if the upload goes through the internet. Using Apache2 seems to fix the problem. Any ideas what the problem may be? Thanks, Viktor
