First pass, uncompiled yet

cabal install is currently failing with "Unexpected response 503for http://objects-us-west-1.dream.io/hackage-mirror/package/xss-sanitize-0.3.5.7.tar.gz", so I'm pausing for the evening!

This PR is a work-in-progress; it will be redirected to haskell/hackage-server when appropriate.

• Consider removing 'id=' altogether, or creating two separate ids for the divs?
• Make a link in 'consider selecting a preferred version'?
• Will the lookup that finds the current id's version ever actually fail? ... == Just DeprecatedVersion looks silly, but maybe it's a small price for totality.

Btw, feel free to post screenshots... so we can see what it looks like w/o having to build this PR :-)

@gbaz you suggested just using Hackage directly to avoid the (persistent) error on the mirror. Sounds like a good idea. In fact, I have no idea why cabal is using a mirror in the first place. I know even less about specifying a mirror, or indeed unspecifying one. I searched the cabal manual to no avail, and there don't appear to be pointers in the --help output either. What did I miss? :)

[gbaz]

Cabal auto-falls back to mirrors if it has problems contacting the main server. You may have accidentally specified a mirror in your ~/.cabal/config file otherwise.

If you persistently have trouble connecting to hackage, you may want to play around with your --http-transport settings... (In particular, if you're on windows, you probably want to not use powershell for the time being, since cabal-install had a persistent bug with it that was recently fixed).

I found the 'remote-repo' setting, which looks ok in .cabal/config:

repository hackage.haskell.org
  url: http://hackage.haskell.org/

I am in fact on Linux. The problem is persisting, but just for that one package, xss-sanitize. Everything else is downloading fine. Is there something wrong with this package?

Bizarre! You may find better luck switching transports anyway (as a way of avoiding some sort of weird caching issue -- to be honest i have no idea). For what its worth, I can download from that location on my computer just fine...

[chreekat]

Ugh. I was bit by NixOS/nix#395 , though perhaps cabal-install could have reported the error better. (With more verbosity, I did see the "out of space" messages.)

[chreekat]

My next blocker is that building hackage-server on NixOS has not proven to be straightforward.

1. Depending on system libraries (libz) requires setting Cabal flags I haven't used much
2. Using recent multi-library Cabal features confounds cabal2nix
3. Writing a Nix expression by hand is probably doable, but slightly onerous

It won't take much research to square this away, but that's where I am for the time being.
