#10550: Drop truncated package name prefix from package keys -------------------------------------+------------------------------------- Reporter: ezyang | Owner: ezyang Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Package system | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by ezyang): Backwards compatibility considerations: GHC 7.10.1/7.10.2 will ship with libraries that are installed as `ghcpr_8TmvWUcS1U1IKHT0levwg3`, so Cabal will need to continue to understand this format. However, GHC is indifferent to how you pick future `-this-package-key`, so Cabal can simply generate `8TmvWUcS1U1IKHT0levwg3` for any subsequent installations and GHC wouldn't mind. (Old Cabal would not be able to read the package database however, because the parser is not setup to understand `8TmvWUcS1U1IKHT0levwg3`, but `ghc-pkg` doesn't validate the format so this would simply translate into not being able to use Cabal to manage a more recent package database, which I think already applies.) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10550#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
