btw, how about using for *Haskell* code *default* signal handler that raise Haskell exception? i think that using signal handlers to process OS-generated events is just legacy from the C days. i.e. 'main' should be called by RTS inside code like this:
mainThread <- myThreadId let onBreak event = do throwTo mainThread BreakException bracket (installHandler$ Catch onBreak) (installHandler) $ \oldHandler -> do main
(of course, this handles only ^Break and only on Windows)
among other things, this should make signal handling portable between Win/Unix
Yes, we've discussed this in the past (e.g. there was a thread about this on the haskell-prime list). I'm definitely in favour of doing something along these lines.
how about adding such facility to ghc HEAD? i can write initial windows implementation and put it to discussion here or in ghc maillist
I don't have a clear idea for the design, I'd have to go back and look at the haskell prime discussion. Do you want to propose something? Cheers, Simon
