Paul Brown posted this discussion back in February. It looks like the same thing. Has there been an update of HTTP since then?
Nope, it hasn't been updated. I'm just running a locally patched version. This is the same issue, thanks!
Looks like there is a patch committed to http's darcs repo, 3rd May, from prb to address this problem.
If someone could figure out the right fix and send it to the maintainer that'd be great. We do need a decent working pure-haskell http package.
Agreed. I think http needs serious work before it would fit the bill though.
For one thing cabal-install uses the HTTP package and it has to work for downloading dozens or hundreds of packages in a single session.
As an aside, cabal-install could use the Network.Browser module better, by using a single call to browse for all downloads rather than one per download. As I understand it, that'd allow it to re-use a single connection.
It's quite likely you are leaking a connection on every call to browse. I recall someone asking about how to configure hackage's Apache to handle more than 1000 open connections... maybe cabal-install is the reason for it needing so many concurrent connections. I've sent a patch for Network.Browser.browse to Bjorn. Dan
