[hunchentoot-devel] edicl & Quicklisp - formal release tarballs or production-ready master branches?
by Sebastian Tennant 09 Sep '11

09 Sep '11

Hi Hans, I recently wrote the following post on the Quicklisp mailing list: http://permalink.gmane.org/gmane.lisp.quicklisp/69 and you can read Zach's reply here: http://permalink.gmane.org/gmane.lisp.quicklisp/70 Here's the final paragraph of Zach's reply, for the sake of convenience: "If the updated Ediware projects have important improvements, I would love to see new versioned releases published in some formal way. If that's not going to happen, I can look into pulling the projects from git [...]" I suspect formal release tarballs for each and every project in edicl would be quite a lot of work for you (as it probably was for Edi) so how about maintaining production-ready master branches (as in git-flow[1]) to make things as easy as possible for Zach?

[hunchentoot-devel] Hunchentoot development is moving to github
by Hans Hübner 03 Sep '11

03 Sep '11

Hi, effective immediately, Hunchentoot development is going on in github: https://github.com/edicl/hunchentoot - The BKNR subversion repository will be closed in a while, and github will be the authoritative source for development versions. Feel free to fork, send pull requests, open issues and discuss commits. The "edicl" organization on github also has repository for several other libraries that Edi has written. No current development plans exist, but if you have enhancements to any of these libraries, pull requests are welcome. -Hans

[hunchentoot-devel] Two bugs in development head (stable version unaffected)
by Wukix Inc. 29 Aug '11

29 Aug '11

Hello All, We have become aware of what seems to be two bugs in Hunchentoot svn head (stable version is unaffected). The first one was discovered by, and should be credited to J.P. Larocque. The issue is that not only is Content-Range unnecessarily included in HTTP responses, but the upper value of the range is off by 1. For example, look at these response headers: < HTTP/1.1 200 OK < Content-Length: 14260 < Content-Range: bytes 0-14260/* J.P.'s analysis follows: =============== Content-Range appears in response, but the status code is 200 rather than 206 (Partial Content). That's odd, but not illegal as far as I can tell. But the Content-Length is definitely inconsistent with the Content-Range. HTTP 1.1 byte ranges are inclusive: The last-byte-pos value gives the byte-offset of the last byte in the range; that is, the byte positions specified are inclusive. Byte offsets start at zero. -- HTTP 1.1 14.35.1 Byte Ranges http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35 So a range of [0,14260] indicates a length of 14261 bytes, but that's different from the Content-Length value. =============== The second issue, which was our own discovery, is that the content-type will be incorrect when serving a 304 (Not Modified) response. The content-type issue can be reproduced in Chrome/Chromium with the developer tools enabled. Basically, request some page while viewing the network tab. When you hit refresh (triggering status 304 instead of first visit 200), you will see the content type will be incorrect for images, javascript, or any other non-html. The content-type issue seems to be caused by a change to the order of operations within handle-static-file of misc.lisp. The content type needs to be set before before calling handle-if-modified-since, which could otherwise abort before the proper content type is set. Both of these issues can be fixed by reverting to an earlier version of misc.lisp. As we already mentioned, the stable version of Hunchentoot is not affected. Thanks, The Team at Wukix, Inc.

Hi everyone i am new to web programming and hunchentoot. i have the following question: How do one get client's time with hunchentoot? Does the http request contain this information and can one inspect on that within hunchentoot? Or what is the other way to do it? On my main page, i need to know the exact hour and minute of the client before generating the appropriate site content. Thanks Matus

[hunchentoot-devel] Timing out when reading long post requests?
by Oleg Sivokon 07 Jul '11

Hello, I'm not sure what is causing this error (please see the stack trace below), all I can say it's relatively big XML being sent. I must be doing something tremendously inefficient or else this error means something else, but I hope you would be able to advise: [2011-07-06 14:20:27 [ERROR]] I/O timeout reading #<SB-SYS:FD-STREAM for "a socket" {B8E0AA1}>. 0: (SB-DEBUG::MAP-BACKTRACE #<CLOSURE (LAMBDA #) {B9034D5}>)[:EXTERNAL] 1: (BACKTRACE 536870911 #<SB-IMPL::STRING-OUTPUT-STREAM {B903471}>) 2: (TRIVIAL-BACKTRACE:PRINT-BACKTRACE-TO-STREAM #<SB-IMPL::STRING-OUTPUT-STREAM {B903471}>) 3: (HUNCHENTOOT::GET-BACKTRACE) 4: ((FLET #:LAMBDA284) #<SB-SYS:IO-TIMEOUT {B903139}>) 5: (SIGNAL #<SB-SYS:IO-TIMEOUT {B903139}>)[:EXTERNAL] 6: (ERROR SB-SYS:IO-TIMEOUT)[:EXTERNAL] 7: (SB-IMPL::SIGNAL-TIMEOUT SB-SYS:IO-TIMEOUT)[:EXTERNAL] 8: (SB-IMPL::REFILL-INPUT-BUFFER #<SB-SYS:FD-STREAM for "a socket" {B8E0AA1}>) 9: (SB-IMPL::FD-STREAM-READ-N-BYTES #<SB-SYS:FD-STREAM for "a socket" {B8E0AA1}> #(97 108 121 116 105 99 115 62 10 32 32 102 49 50 51 52 53 54 55 56 57 48 . . . long array of data ) 0 8191 NIL) 10: (SB-IMPL::ANSI-STREAM-READ-SEQUENCE #(97 108 121 116 105 99 115 62 10 32 32 102 49 50 51 52 53 54 55 56 57 48 . . . long array of data ) #<SB-SYS:FD-STREAM for "a socket" {B8E0AA1}> 0 8191) 11: (READ-SEQUENCE #(97 108 121 116 105 99 115 62 10 32 32 102 49 50 51 52 53 54 55 56 57 48 . . . long array of data ) #<SB-SYS:FD-STREAM for "a socket" {B8E0AA1}>)[:EXTERNAL] 12: ((SB-PCL::FAST-METHOD TRIVIAL-GRAY-STREAMS:STREAM-READ-SEQUENCE (FLEXI-STREAMS:FLEXI-INPUT-STREAM T T T)) #<unavailable argument> #<unavailable argument> #<unavailable argument> #<unavailable argument> #<unavailable argument> #<unavailable argument>)[:EXTERNAL] 13: ((LAMBDA (SB-PCL::.PV.

*Hi, If I want to serve web pages encoded in UTF-8, I should set these two variables : (setf hunchentoot:*default-content-type* "text/html; charset=UTF-8") (setf hunchentoot:*hunchentoot-default-external-format* hunchentoot::+utf-8+) Am I correct ? Is it ok to use an internal symbol (+utf-8+) or is there another way ? Thanks, * -- Thibault Langlois FCUL / DI
