Re: [Haskell-cafe] ANN: HTTPbis / HTTP-4000.x package available

Thanks Jeff, regarding having to use both HTTP and cURL -- or perhaps only the latter for code simplicitly -- that will probably remain the case for quite a while still. To help with that situation, I put together an over-arching 'webclient' library that abstracts over the transport layers (HTTP, curl, curl-shell) giving you an API that's consistent across backends. I could release that at some point if there's sufficient interest.. It also adds WebDAV support. Re: curl - as an author of the 'curl' package, I'm also keen on finding ways of making that better -- both in terms of using the underlying lib functionality and API on the Haskell side. Suggestions/contribs most welcome. Ditto for HTTP too, of course :) --sigbjorn On 1/16/2009 05:47, Jeff Heard wrote:

Just as a reported speedup, downloading a 5MB file from my own local machine (via http) went from 1.05 secs to 0.053 secs. Yes, it's really an order of magnitude better. Performance now is on par or slightly better than cURL (however to get more protocols than HTTP, you'll still need the ubiquitous cURL library)

Hi,

I guess it's time to publish more widely the availability of a modernization of the venerable and trusted HTTP package, which I've been working on off&on for a while.

Bunch of changes, but the headline new feature of this new version is the parameterization of the representation of payloads in both HTTP requests and responses. Two new representations are supported, strict and lazy ByteStrings. Some people have reported quietly pleasing speedups as a result of this change. (If they want to report numbers, please do..)

Another change/fix in this release is the _alleged_ fix to the long-standing bug in the use of absolute URIs vs absolute paths in requests (for non-proxied and proxied use.) Give it a go..

Notice that the HTTP-4000.x version will require you to make some modifications to your existing HTTP-using code -- I've tried to keep the API backwards compatible minimal despite the change in functionality and underlying types. If you do not want to deal with this right away, please introduce a <4000 dependency on the HTTP package in your .cabal files.

I've also taken on the maintainership of the package, with the highly esteemed Bjorn Bingert no longer having the usual abundance of cycles to look after it (hope I'm not misrepresenting facts here, Bjorn!) However, I've yet to gain access to www.haskell.org and update http://www.haskell.org/http, so for now you may pick up a new version the lib via
