patch applied (hackage-server): "Introduce TarIndexCache feature"

Wed Jan 23 11:40:35 GMT 2013 Edsko de Vries * Introduce TarIndexCache feature Ignore-this: 9450fc9a76131a0fa21329f67d4a6540 This provides generic support for caching tarball indices. The package contents feature now uses this to get access to the tar index. We no longer reconstruct the tar index on every request! Whoohoo :) M ./Distribution/Server/Features.hs +4 R ./Distribution/Server/Features/PackageContents/ M ./Distribution/Server/Features/PackageContents.hs -65 +51 R ./Distribution/Server/Features/PackageContents/State.hs A ./Distribution/Server/Features/TarIndexCache/ A ./Distribution/Server/Features/TarIndexCache.hs A ./Distribution/Server/Features/TarIndexCache/State.hs M ./hackage-server.cabal +3
