From 69ef3f1025fb32a19f03517d072c1e64dcb326b7 Mon Sep 17 00:00:00 2001 From: Joey Hess Date: Thu, 7 Aug 2014 21:55:44 -0400 Subject: unify exception handling into Utility.Exception Removed old extensible-exceptions, only needed for very old ghc. Made webdav use Utility.Exception, to work after some changes in DAV's exception handling. Removed Annex.Exception. Mostly this was trivial, but note that tryAnnex is replaced with tryNonAsync and catchAnnex replaced with catchNonAsync. In theory that could be a behavior change, since the former caught all exceptions, and the latter don't catch async exceptions. However, in practice, nothing in the Annex monad uses async exceptions. Grepping for throwTo and killThread only find stuff in the assistant, which does not seem related. Command.Add.undo is changed to accept a SomeException, and things that use it for rollback now catch non-async exceptions, rather than only IOExceptions. --- RemoteDaemon/Transport/Ssh.hs | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'RemoteDaemon') diff --git a/RemoteDaemon/Transport/Ssh.hs b/RemoteDaemon/Transport/Ssh.hs index 65c313852..db6b6127c 100644 --- a/RemoteDaemon/Transport/Ssh.hs +++ b/RemoteDaemon/Transport/Ssh.hs @@ -108,10 +108,10 @@ data Status = Stopping | ConnectionClosed {- Make connection robustly, with exponentioal backoff on failure. -} robustly :: Int -> IO Status -> IO () -robustly backoff a = handle =<< catchDefaultIO ConnectionClosed a +robustly backoff a = caught =<< catchDefaultIO ConnectionClosed a where - handle Stopping = return () - handle ConnectionClosed = do + caught Stopping = return () + caught ConnectionClosed = do threadDelaySeconds (Seconds backoff) robustly increasedbackoff a -- cgit v1.2.3
