#11069: :cd in GHCi unloads modules -------------------------------------+------------------------------------- Reporter: mgsloan | Owner: Type: bug | Status: new Priority: low | Milestone: Component: GHCi | Version: 7.10.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Other Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- If I run `stack ghci` in the [https://github.com/commercialhaskell/stack stack] repo, and then use `:cd`, I get the following:
Warning: changing directory causes all loaded modules to be unloaded, because the search path has changed.
And, indeed, all modules are unloaded. What's particularly strange about this is that in my case all of the paths provided on the commandline are absolute. Here's the output of ":show paths":
current working directory:
/home/mgsloan/fpco/stack
module import search paths:
/home/mgsloan/fpco/stack/src
/home/mgsloan/fpco/stack/.stack- work/dist/x86_64-linux/Cabal-1.22.4.0/build/autogen
/home/mgsloan/fpco/stack/.stack- work/dist/x86_64-linux/Cabal-1.22.4.0/build
/home/mgsloan/fpco/stack/src/main
How about removing any dependency in GHC on the current working directory, and instead store it when the session is initialized? This is also necessary if we want to support per-package working directories, [https://ghc.haskell.org/trac/ghc/timeline?from=2015-11-08T06%3A17%3A58Z&precision=second details here]. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11069 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
