#809: Improve update performance ---------------------------------+------------------------------------------ Reporter: bos | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ---------------------------------+------------------------------------------ I have an automated package build set up using Hudson, and it tries to build my code as often as once every 5 minutes. Right now, that means running cabal update before every build, which takes at least 30 seconds. It would be great if cabal update used the ETag and If-Modified-Since HTTP headers to do conditional fetches of the metadata, so that there would be far less of a performance hit to both the Hackage server and my client. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/809 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
