#15660: source file modify race leads to inconsistent error message -------------------------------------+------------------------------------- Reporter: joeyhess | Owner: (none) Type: bug | Status: new Priority: low | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: Operating System: Linux | Architecture: Type of failure: Poor/confusing | Unknown/Multiple error message | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by joeyhess): When I experienced this in the wild, the only problem was the surprise that it was mixing versions of the file; once past the surprise it was little bother to need to look up the code manually. So it would probably suffice for ghc to detect the race and not quote the wrong version of the file. I suppose it could use file stat information or a hash and so avoid keeping a copy. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15660#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
