#288: the package indexes are very slow ---------------------------------+------------------------------------------ Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: normal | Keywords: Difficulty: easy (<4 hours) | Ghcversion: 6.8.2 Platform: | ---------------------------------+------------------------------------------ Comment(by duncan): Replying to [comment:5 AntoineLatter]:

Experience report:

Taking the tar-index from hackage-server wasn't too hard. It doesn't scale to hackage-sized tarballs, though - it is only able to store the offsets for about half of the .cabal files in 00-index.tar.

It should be straightforward to extend the size of the types used to cope with bigger tarballs. The only cost will be a bigger index. The reason for the limitations in the hackage code is simply to save space by keeping the indexes very compact. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/288#comment:6 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
