#5014: canonicalizePath throws exception on paths that do not exist ----------------------------------------+---------------------------------- Reporter: hesselink | Owner: Type: bug | Status: new Priority: low | Milestone: 7.6.2 Component: libraries/directory | Version: 7.0.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Runtime crash | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: ----------------------------------------+---------------------------------- Comment (by Blaisorblade): Documenting the current behavior is better than nothing, but settling on that seems a regression from portable languages to C. I want to argue that settling on platform-dependent behavior is a worse idea than figuring out a sensible platform-independent behavior, possibly by surveying other languages (Python as proposed above, or maybe Java). Additional system-specific APIs are probably fine for lower-level development, but they seem lower-priority to me. This bug keeps causing portability problems for Haskell applications. I remember cabal needed fixing for this; right now I ran into this for hp2any-graph, which tries to canonicalize a filename that is going to appear. Therefore, quite a few programs that use canonicalizePath and were developed on Linux only break on other platforms. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/5014#comment:16 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
