Hi, Please follow up on the mailing list (see Cc). I can't see the error and I can't open your attachment. Which browser and OS are you using? Thanks, Edi.

[hunchentoot-devel] ht-simple-ajax
by Martin Loetzsch 02 Feb '10

02 Feb '10

Hi all, I recently posted here about HT-AJAX and Hunchentoot, which are kind of out of sync. I tried to make a patch for HT-AJAX that makes it compatible with newer versions of Hunchentoot, but I soon gave up because it seemed to me that a lot of functionality was already broken before Hunchentoot 1.0 came out. So I decided to make HT-SIMPLE-AJAX, which can do only 10% of what HT- AJAX could do. On the other hand, that's what I needed for GTFL (http://martin-loetzsch.de/gtfl ). And it's very elegant (only 150 loc) and works together with newer Hunchentoot versions: http://martin-loetzsch.de/ht-simple-ajax/ Hoping that somebody finds this useful, Martin Loetzsch

[hunchentoot-devel] silly issue with session and Hunchentoot due to warning
by Mackram Raydan 01 Feb '10

01 Feb '10

Hey Everyone, I am fairly certain that there must be an easy workaround to the issue I am experiencing but I might be blind to it. I am using Hunchentoot in the backend to handle a few things part of which is the session. Unfortuanetly it causes an error everytime I try to use the session I get a dump similar to this (I have cut it a bit to make more sense) 32SIGNAL 1. Couldn't write to #<SB-SYS:FD-STREAM for "standard error" {1002782181}>: Input/output error 31ERROR 1. SIMPLE-STREAM-ERROR 30SIMPLE-STREAM-PERROR 1. Couldn't write to ~s 2. #<FD-STREAM for "standard error" {1002782181}> 3. 5 23INTERPRET-FORMAT-LOGICAL-BLOCK 1. #&l t;SYNONYM-STREAM :SYMBOL SB-SYS:*STDERR* {1000148D21}> 2. (WARNING Session secret is unbound. Using Lisp's RANDOM function to initialize it.) 3. (WARNING Session secret is unbound. Using Lisp's RANDOM function to initialize it.) 4. 5. NIL 6. (#<~S> : #<~3i> #<~:_> #<~A>) 7. 8. T As you can see the problem is that it could not dump the warning on the standard output. My guess is that I should stop the warning but trying to do (setf hunchentoot:*log-lisp-warnings-p* nil) did not work with it. Can anyone suggest what i am missing?

[hunchentoot-devel] Authorization data being cached
by Patrick May 28 Jan '10

28 Jan '10

I don't think this is a Hunchentoot issue, but I thought I'd ask here first. I've noticed that Safari seems to cache the basic authorization username and password, so that even if I call (remove-session *session*) on the server side, Safari just reloads the page. Am I interpreting the behavior correctly? If so, how do I force a re-authorization? Thanks, Patrick

[hunchentoot-devel] Exception in USOCKET:GET-PEER-ADDRESS brakes ACCEPT-CONNECTIONS loop
by Anton Vodonosov 26 Jan '10

26 Jan '10

Hello, On one server running hunchentoot quite often the following error occurs: 23: (SB-IMPL::%WITH-STANDARD-IO-SYNTAX #) 24: (INVOKE-DEBUGGER #) 25: (ERROR SB-BSD-SOCKETS:NOT-CONNECTED-ERROR)[:EXTERNAL] 26: (SB-BSD-SOCKETS:SOCKET-ERROR "getpeername") 27: ((SB-PCL::FAST-METHOD SB-BSD-SOCKETS:SOCKET-PEERNAME (SB-BSD-SOCKETS:SOCKET)) # # #) 28: ((SB-PCL::FAST-METHOD USOCKET:GET-PEER-ADDRESS (USOCKET:STREAM-USOCKET)) # # #) 29: (HUNCHENTOOT::CLIENT-AS-STRING #) 30: ((SB-PCL::FAST-METHOD HUNCHENTOOT:HANDLE-INCOMING-CONNECTION (HUNCHENTOOT:ONE-THREAD-PER-CONNECTION-TASKMASTER T)) ..) 31: ((SB-PCL::FAST-METHOD HUNCHENTOOT:ACCEPT-CONNECTIONS (HUNCHENTOOT:ACCEPTOR)) # # #) 32: ((LAMBDA ())) As you see, it happens in USOCKET:GET-PEER-ADDRESS called in HANDLE-INCOMING-CONNECTION before the request handling thread is started. This exception breaks the main loop in ACCEPT-CONNECTIONS and server doesn't handle HTTP requests anymore. Most probably these errors are very rare in general, but on this particular machine they happen constantly. Adding ignore-errors to the loop helps - the server doesn't hang anymore. Best regard, - Anton P.S. The problem and the fix suggested are discovered by Andrey Moskvitin, I am just reporting it here.

[hunchentoot-devel] Returning a unicode string from a handler fails silently
by Ron Garret 23 Jan '10

23 Jan '10

Subject line says it all. If I have a handler that returns a string that has a non-ascii character in it then the handler fails silently. No headers. No log messages. No errors. No nothing. And as long as I'm at it, what does TBNL stand for? Thanks, rg

[hunchentoot-devel] Hunchentoot 1.1 + HT-Ajax
by Martin Loetzsch 14 Jan '10

14 Jan '10

Dear all, recent changes in Hunchentoot prevented ht-ajax from compiling. This is easy to fix locally, but I don't know what to do so that the version on this site also works: http://common-lisp.net/projecs/ht-ajax/ This is bad because a library of mine ( http://martin-loetzsch.de/ gtfl ) uses both hunchentoot and ht-ajax and people who try to install it will asdf:install with fail. Do you know who currently feels responsible for ht-ajax? Or who Mr or Mrs 'xlopez' on http://common-lisp.net/websvn/listing.php?repname=ht-ajax is? Or who to ask for changing the .tar.gz file on common-lisp.net? Thanks for your time, Martin Loetzsch

[hunchentoot-devel] Missing hunchentoot-test.asd in Hunchentoot 1.1.0
by Nico de Jager 11 Jan '10

11 Jan '10

Hi The tar archive of Hunchentoot 1.1.0 on weitz.de is missing the hunchentoot-test.asd file, which is surely by accident since the documentation still mentions it. Thanks for the new version! Nico
