#8244: Removing the Cabal dependency -------------------------------------+------------------------------------- Reporter: nh2 | Owner: duncan Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: | Blocked By: None/Unknown | Related Tickets: Test Case: | Blocking: | Differential Revisions: D172 | -------------------------------------+------------------------------------- Comment (by refold): Replying to [comment:29 duncan]:
It could read the text files, but this would be slower than using the binary cache. The performance of ghc-pkg dump is actually important. It's used by cabal to get the installed packages.
Maybe Cabal should have its own binary cache for the data it gets out of `ghc-pkg dump`? We can check whether compiler's package DB is older than our cache and only use the slow path (`ghc-pkg dump`) when it's not. Perhaps we could also share the `Binary` instance for `InstalledPackageInfo` between `Cabal` and `ghc-pkg`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8244#comment:31 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
