[hunchentoot-devel] Problems with file uploads and mod_lisp
by Edi Weitz 07 Nov '06

07 Nov '06

Hi! I just realized that Hunchentoot in its current form has problems with file uploads if it's used behind mod_lisp. I could reproduce this with Apache 2 as well as Apache 1 and with LispWorks (but only on Linux, not on Windows) as well as with SBCL. To try this yourself, start the demo that comes with Hunchentoot and upload a couple of pictures (I used JPEGs) in the file upload section. Click on the uploaded pictures and view them. Symptoms that I see: - files are sometimes uploaded only partly - you see an Apache error message after an upload is finished (which usually means that mod_lisp can't talk to Lisp) - server gets completely unresponsive after some time It seems this is not deterministic, though. I've had situations where I uploaded the same picture a couple of times, and sometimes the whole file reached the server, sometimes only a part of it. One of the reasons for this that I could observe is that when rfc2388.lisp reads characters from the content stream, READ-CHAR sometimes returns NIL although the whole file hasn't been transferred yet (i.e. there should be more input available). I'm writing this because I haven't found the reason for this behaviour yet and I'll probably be too busy in the next days to do something about it. Obviously, I'd be happy if someone else would debug this and find a solution. Meanwhile, maybe you shouldn't use Hunchentoot with mod_lisp for production servers. The stand-alone version doesn't seem to be affected, though. Cheers, Edi.

[hunchentoot-devel] Bug Report: AUTHORIZATION
by Michael J. Forster 26 Oct '06

26 Oct '06

Hi Edi, I found a bug in AUTHORIZATION. If I click the "Authorization" link on the Hunchentoot test page and submit an empty username and password, instead of prompting me again, the server returns `Internal Server Error'. In this case, the call to SPLIT returns nil, which does not match the DESTRUCTURING-BIND lambda list. My first reaction was simply to rewrite the DESTRUCTURING-BIND to permit a nil username as well as password: (destructuring-bind (&optional user password) (split ":" (base64:base64-string-to-string (subseq authorization start))) (values user password)) Then, we would get (VALUES NIL NIL), which would seem consistent with the documentation. However, I also realised that AUTHORIZATION will return just nil if the auth header doesn't exist. Should that be documented? Here's my environment: * Hunchentoot 0.4.4 (no Apache, no mod_lisp) * latest versions (as of today) of dependencies * LispWorks 4.4.6 * OS X 10.4.8 * Safari 2.0.4 * Firefox 1.5.0.7 Regards, Mike P.S. Started migrating our apps from Portable AllegroServe to Hunchentoot this past week. Very pleased with the API and performance. Thanks! -- Michael J. Forster <mike(a)sharedlogic.ca>

[hunchentoot-devel] How to use/generate/access javascript/css?
by Vamsee Kanakala 23 Oct '06

23 Oct '06

Hi all, Sorry for the newbie questions, I'm curious as to how people working with tbnl/hunchentoot create/maintain their javascript and css files. If you use js/css generators, what are those (I know of only parenscript). If I'm using cl-who to generate my html, how can I include a .css or .js file in this code (or, where do I need to place these files to be accessible by hunchentoot? TIA, Vamsee.

[hunchentoot-devel] Comparisons with araneida?

Does anyone have any comments on tbnl (now Hunchentoot) and araneida? I'd be interested in anyone that switched from araneida, features comparisons, stability, idiosyncrasies and so on. Jonathon McKitrick -- My other computer is your Windows box.

Fwd: [hunchentoot-devel] Latest rfc2388
by Marijn Haverbeke 16 Oct '06

(Accidentally sent this just to Edi, forwarding to list) ---------- Forwarded message ---------- From: Marijn Haverbeke <marijnh(a)gmail.com> Date: Oct 16, 2006 12:38 PM Subject: Re: [hunchentoot-devel] Latest rfc2388 To: Edi Weitz <edi(a)agharta.de> It would be helpful if you could tell us what exactly is not working > for you, which Lisp you are using, etc. On close inspection, the problem is not with Hunchentoot or rfc2388. It turns out I was previously using an rfc2388 from a repository mainained by the UCW people, who have apparantly branched it and made a few incompatible changes. So you can safely ignore these messages. Regards, Marijn

[hunchentoot-devel] Latest rfc2388
by Marijn Haverbeke 16 Oct '06

16 Oct '06

Hello list, There appears to be some kind of incompatible interface change between the rfc2388 that can be found at cliki.net and the latest version of the library from common-lisp.net/project/rfc2388. After some head scratching I figured out that Hunchentoot was not working on my system because it uses the older version of rfc2388. So now I am switching between these versions of the library a lot, since UCW requires the other, newest version. Are there any plans to switch Hunchentoot to the latest version? Or do you wait until a new version is 'released'? I don't really know how the release process for rfc2388 works, or when a new version is due. Regards, Marijn

[hunchentoot-devel] Comparisons with araneida?
by Jonathon McKitrick 15 Oct '06

Hi all, the new release of Hunchentoot for other lisps piqued my interest. I've been deploying on araneida, but I've run into some issues that have required less than ideal workarounds. So, I just thought I'd check out Hunchentoot as an alternative. So for basic webapps with ajax functionality (XMLHttpRequest), how would you say the 2 platforms stack up?
