#428: cabal update uses too much bandwidth ---------------------------------+------------------------------------------ Reporter: claus | Owner: Type: defect | Status: new Priority: normal | Milestone: cabal-install-0.8 Component: cabal-install tool | Version: 1.6.0.1 Severity: normal | Resolution: Keywords: | Difficulty: hard (< 1 day) Ghcversion: 6.8.3 | Platform: ---------------------------------+------------------------------------------ Comment (by duncan): One approach I was thinking of was providing the uncompressed tarball and mostly use it append only. So most clients could do a conditional request for the byte range from the point they have currently to the end of the file. If the cache ends up not matching then the client can just request the whole compressed tarball. That uses standard HTTP-1.1 without needing anything special on the server side which is important if we want to let people host dumb repos easily. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/428#comment:4 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
