#15292: ghc_ticker loops if permission denied on timerfd ---------------------------------------+---------------------------------- Reporter: jon.fairbairn@… | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.2.2 Keywords: | Operating System: Linux Architecture: x86_64 (amd64) | Type of failure: Runtime crash Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: ---------------------------------------+---------------------------------- Using stack with lts-11.6 to compile a cgi programme, I got something that runs OK from the command line, but which goes into a busy loop when run from httpd. This is caused by selinux preventing read on the timer. Changing the selunix permissions solves the problems, but ghc-ticker ought to check whether the read succeeded and not try again if it fails. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15292 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
