Re: [Haskell-cafe] Network.HTTP problem
Hello again Bjorn, This is now fixed and a new release with the fix is available from http://hackage.haskell.org/cgi-bin/hackage-scripts/package/HTTP-3001.0.1 You have left debug flag on in the library code.

Thanks, Radek. Dammit. I forgot that cabal sdist of course uses the code in the current directory, not what's recorded in darcs. Silly me. 3001.0.2 fixes this, http://hackage.haskell.org/cgi-bin/hackage-scripts/ package/HTTP-3001.0.2 Thanks! /Björn ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
[Haskell-cafe] Network.HTTP problem
Hello, I have a problem with Network.HTTP module (http://www.haskell.org/http/) version 3001.0.0 . I have already mailed Bjorn Bringert about it but I didn't get answer yet so maybe someone here can help me. GHC v. 6.6.1 Ubuntu 7.10 x86_64 . I have turned on debug flag. Using get example (http://darcs.haskell.org/http/test/get.hs) I can download pages like this: $ ./get http://www.haskell.org/http/ !DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Strict//EN http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd; html xmlns=http://www.w3.org/1999/xhtml; head titleHaskell HTTP package/title link href=style.css rel=stylesheet type=text/css / /head body SNIP rest of the content SNIP Also the log contain content of this file. However, some links misbehaves like: $ ./get http://www.podshow.com/feeds/gbtv.xml ... no-output ... however I see content of this xml in debug file and wget downloads almost 250 kB of data. Also: $ ./get http://digg.com/rss/indexvideos_animation.xml ... hangs ... and debug file has size 0, but wget downloads the file I could suspect this is xml problem but: $ ./get http://planet.haskell.org/rss20.xml ?xml version=1.0? rss version=2.0 xmlns:dc=http://purl.org/dc/elements/1.1/; channel titlePlanet Haskell/title linkhttp://planet.haskell.org//link languageen/language descriptionPlanet Haskell - http://planet.haskell.org//description SNIP rest of the content SNIP so it works. Do you have any idea what is going on here? What goes wrong? What other (high level) modules could I use to download files through http? Cheers, Radek. -- Codeside: http://codeside.org/ Przedszkole Miejskie nr 86 w Lodzi: http://www.pm86.pl/ ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

Do you have any idea what is going on here? What goes wrong? What other (high level) modules could I use to download files through http? Cheers, Radek. Hi Radek, thanks for the report. This turned out to be a bug in how Network.HTTP handled Chunked Transfer Encoding. The web server sent the chunk size as 4000 (according to RFC 2616 this can be non-empty sequence of hex digits). However, Network.HTTP treated any chunk size starting with '0' as a chunk size of 0, which indicates the end of the chunked encoding. This is now fixed and a new release with the fix is available from http://hackage.haskell.org/cgi-bin/hackage-scripts/package/HTTP-3001.0.1 /Björn ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

However this one still seems to hang and eventually ends with :
get: recv: resource vanished (Connection reset by peer)
It's not a Haskell problem. It looks like Digg expects a User-Agent
request header. Modify get.hs like this:
request uri = Request{ rqURI = uri,
rqMethod = GET,
rqHeaders = [Header HdrUserAgent haskell-get-example],
rqBody = }
and see what happens.
