#8433: forkProcess masks async exceptions inside the child process ------------------------------------+--------------------------------- Reporter: joeyh | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/unix | Version: 7.6.3 Keywords: | Operating System: Linux Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+--------------------------------- Frankly, I'm not sure if this is a bug, but the forkProcess documentation says nothing about it. This can lead to problems when writing a multi- threaded daemon that expects async exceptions to work as they usually would. FWIW, I have looked at several of the libraries on hackage that handle daemonization, and none of them seem to deal with this by explicitly unmasking exceptions when running the daemon IO action. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8433 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
