#7229: Detecting if a process was killed by a signal is impossible --------------------------------------+------------------------------------ Reporter: benmachine | Owner: Type: bug | Status: new Priority: highest | Milestone: 7.8.1 Component: libraries/process | Version: Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: --------------------------------------+------------------------------------ Comment (by duncan): @andersk just to play devil's advocate for a moment: why not use negative encoding for signals, and just ignore the core dump bit? It gives an encoding that is very simple to use and very few people care about core dumps (and if they do, they can use the unix package). `-n` is a lot easier than {{{(n .&. 0x7f00) `shiftR` 8}}}. Indeed people are likely to do it wrong and just use {{{n `shiftR` 8}}} in which case they'll get tripped up whenever there is a core dump (which is platform configuration specific). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7229#comment:40 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
