#15768: Using oneshot kqueue() on macOS -------------------------------------+------------------------------------- Reporter: kazu-yamamoto | Owner: (none) Type: bug | Status: patch Priority: highest | Milestone: 8.8.1 Component: Core Libraries | Version: 8.6.1 Resolution: | Keywords: KQueue, | oneshot, parallel build Operating System: MacOS X | Architecture: | Unknown/Multiple Type of failure: Other | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by George): Ah ok, I was wondering why we didn't see this on Linux but the papers says we weren't using it there. We used epoll. From the paper: "The registerFd func- tion takes the callback table lock, and then inserts (or modifies) an entry in the callback table and registers the event subscription us- ing the underlying OS event notification mechanism, for example epoll [8] on Linux, kqueue [7] on BSD variants, and poll on other OSes" -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15768#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
