[GHC] #10317: Event manager: Multishot registrations only fire once
#10317: Event manager: Multishot registrations only fire once -------------------------------------+------------------------------------- Reporter: bgamari | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.10.2 Component: Compiler | Version: 7.10.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: Incorrect result Unknown/Multiple | at runtime Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- Since D347 the event manager has had support for multishot event registration semantics, allowing the user to receive multiple events on an fd without requiring re-registration. Unfortunately the implementation drops the registration after it fires, resulting in only one callback invocation. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10317 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
