#9606: Improve outdated ghc-pkg cache warning -------------------------------------+------------------------------------- Reporter: nh2 | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.10.1 Component: ghc-pkg | Version: 7.8.2 Keywords: | Operating System: Architecture: Unknown/Multiple | Unknown/Multiple Difficulty: Easy (less than 1 | Type of failure: hour) | None/Unknown Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Sometimes you get this: {{{ WARNING: cache is out of date: /home/user/.ghc/x86_64-linux-7.8.3/package.conf.d/package.cache. Use 'ghc-pkg recache' to fix }}} The warning is correct but a bit confusing, because running `ghc-pkg recache` does nothing here: It will by default update your global package DB, and the DB the warning is about will still be out of date. This seems to have frustrated others as well: https://gist.github.com/mcandre/5789498 I suggest we make the message more clear: `You might have to pass --user to update this cache file`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9606 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
