#13497: GHC does not use select()/poll() correctly on non-Linux platforms -------------------------------------+------------------------------------- Reporter: nh2 | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Runtime System | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #8684, #12912 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by nh2): I found (using [https://hackage.haskell.org/package/base-4.9.1.0/docs/GHC- RTS-Flags.html#v:getRTSFlags getRTSFlags]) that setting `+RTS -I10` will set {{{ idleGCDelayTime = 10000000000 doIdleGC = True }}} even when the threaded RTS is not enabled. I'm not sure if that's a bug, but commit [https://github.com/ghc/ghc/commit/33a84b8c79f 33a84b8c79f] that introduced the idle GC says {{{ The idle GC only happens in the threaded RTS }}} so maybe this is a bug? [https://github.com/ghc/ghc/blob/428e152be6bb0fd3867e41cee82a6d5968a11a26/rts... The line that checks doIdleGC] is clearly outside the `#ifdef THREADED_RTS`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13497#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
