#7229: Detecting if a process was killed by a signal is impossible --------------------------------------+------------------------------------ Reporter: benmachine | Owner: Type: bug | Status: new Priority: high | 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 hvr): Replying to [comment:6 simonmar]:

Unfortunately we can't add the right information to `ExitCode`, because it is a platform-independent type. The correct type already exists: it is called `System.Posix.ProcessStatus`.

{{{#!hs data ProcessStatus = Exited ExitCode | Terminated Signal | Stopped Signal deriving (Eq, Ord, Show) }}}

Unfortunately whoever wrote this forgot to add a `Bool` to indicate a core dump in the `Terminated` constructor. We *could* fix that.

for the record, this has been implemented in [dc29d55b30d95f0838499fb48217e1d22e39d07d/unix] (which is included in the recently released [hackage:unix-2.7.0.0]) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7229#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
