#9168: reading/writing blocking FDs over FD_SETSIZE is broken -------------------------------------+------------------------------------ Reporter: rwbarton | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: libraries/base | Version: 7.8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by slyfox): Replying to [comment:3 nicolast]: trigger this as well? You mean regression introduction? I think not, as fd sanity is checked right before main select() call. As it's a single-threaded runtime case no haskell tasks should be able to be pushed to blocked queue (with very big FD). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9168#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
