#10889: Compiled software can not read UTF-8 characters using readFile when run via Upstart -------------------------------------+------------------------------------- Reporter: SiXoS | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Keywords: | Operating System: Linux Architecture: | Type of failure: Runtime crash Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- Honestly I dont know if this is a problem with Upstart or ghc. I'm Using Ubuntu 14 Create a software that reads from a file containing UTF-8 characters. Compile the program. Running the program from the terminal works but not if you run it via Upstart. It will crash with the following error: "hGetContents: invalid argument (invalid byte sequence)" Minimal Example: Main.hs: {{{#!hs module Main where main :: IO () main = readFile "ex.txt" >>= putStr }}} ex.txt: {{{ å }}} Place ex.txt and the compiled program "Comp" in the same directory "/the/path/" /etc/init/bug-test.conf: {{{ start on runlevel [2345] stop on runlevel [^2345] chdir /the/path/ exec ./Comp }}} If you run ./Comp from the terminal it works. But if you run "sudo service bug-test start" and then check "/var/log/upstart/bug-test.log" you will see that it has crashed. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10889 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
