#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 osa1): Does anyone know how do other compilers (gcc, clang, ...) do this? I see two options: - Copy the files to /tmp/ before reading, use the files in /tmp/ in consecutive reads. We need to make sure we clean /tmp/ after each run. - Keep the parsed source in memory, use it in caret diagnostics. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15660#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
