[drakma-devel] Help with utf-8 (SBCL 1.0.5)
by Andrei Stebakov 20 May '07

20 May '07

When I make the request like this: (drakma:http-request "http://www.w3.org/2001/06/utf-8-test/UTF-8-demo.html") It results in error: "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\"> <html xmlns=\"http://www.w3.org/1999/xhtml\"> <head><title>UTF-8 test file</title></head> <body> <p>Original by Markus Kuhn, adapted for HTML by Martin Dürst.</p> <pre> UTF-8 encoded sample plain-text file debugger invoked on a SB-INT:STREAM-ENCODING-ERROR in thread #<THREAD "initial t hread" {BBDF5A9}>: encoding error on stream #<SB-SYS:FD-STREAM for "standard output" {BBDF859}> (:EXTERNAL-FORMAT :ASCII): the character with code 8254 cannot be encoded. Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL. restarts (invokable by number or by possibly-abbreviated name): 0: [OUTPUT-NOTHING] Skip output of this character. 1: [ABORT ] Exit debugger, returning to top level. (SB-INT:STREAM-ENCODING-ERROR #<SB-SYS:FD-STREAM for "standard output" {BBDF859}> 8254) 0] Is it some parameter that I forgot to call http-request with to make it aware of utf-8 encoding? Thank you, Andrew

[drakma-devel] xml-rpc?
by Cyrus Harmon 13 May '07

has anyone layered xml-rpc on top of drakma? seems like a natural thing to do. s-xml-rpc seems nice, but I don't think it supports https. Thanks, Cyrus

[drakma-devel] Lenient read-line*
by Sean 08 May '07

08 May '07

I've attached a small patch which makes chunga:read-line* a little more lenient with regards to line endings. Currently (drakma:http-request "http://news.ycombinator.com") fails with an EOF since the arc server doesn't respond with CRLF but only uses plain LF. The attached patch works around this by assuming that when a LineFeed is encountered it also designates the end of a line, although it is quite possibly the wrong thing. Cheers, Sean. -- ...Please don't assume Lisp is only useful for Animation and Graphics, AI, Bioinformatics, B2B and E-Commerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list.

[drakma-devel] drakma causes lisp connection close unexpectedly
by Mostafa Razavi 01 May '07

01 May '07

I'm starting to use Drakma in a program of mine, and it seems to work fine for me except in one strange case. I was trying to retrieve a page, with (drakma:http-request "http://cesa.iust.ac.ir/"), that I got "Lisp connection closed unexpectedly: exited abnormally with code 256". I set *header-stream* to see what's happening. This is the result: GET / HTTP/1.1 Host: cesa.iust.ac.ir User-Agent: Drakma/0.7.0 (SBCL 1.0.3; Linux; 2.6.20-15-generic; http://weitz.de/drakma/) Accept: */* Connection: close HTTP/1.1 302 Found Connection: close Date: Mon, 30 Apr 2007 22:52:19 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET X-AspNet-Version: 2.0.50727 Location: /Default.aspx?AspxAutoDetectCookieSupport=1 Set-Cookie: AspxAutoDetectCookieSupport=1; path=/ Cache-Control: private Content-Type: text/html GET /Default.aspx?AspxAutoDetectCookieSupport=1 HTTP/1.1 Host: cesa.iust.ac.ir User-Agent: Drakma/0.7.0 (SBCL 1.0.3; Linux; 2.6.20-15-generic; http://weitz.de/drakma/) Accept: */* Connection: close HTTP/1.1 302 Found Connection: close Date: Mon, 30 Apr 2007 22:52:28 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET X-AspNet-Version: 2.0.50727 Location: /(X(1)S(rmofw345wvkjbzjz54jnyu45))/Default.aspx?AspxAutoDetectCookieSupport=1 Cache-Control: private Content-Type: text/html; charset=utf-8 Content-Length: 194 GET /(X(1)S(rmofw345wvkjbzjz54jnyu45))/Default.aspx?AspxAutoDetectCookieSupport=1 HTTP/1.1 Host: cesa.iust.ac.ir User-Agent: Drakma/0.7.0 (SBCL 1.0.3; Linux; 2.6.20-15-generic; http://weitz.de/drakma/) Accept: */* Connection: close HTTP/1.1 200 OK Connection: close Date: Mon, 30 Apr 2007 22:52:34 GMT Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET X-AspNet-Version: 2.0.50727 Cache-Control: private Content-Type: text/html; charset=utf-8 Content-Length: 72459 Other web pages I have tested work fine, but this is the one page I'm going to work with. Any ideas? Thanks. Homayoon, (new-comer)
