#7773: Waiting on non-kqueue supported files on OS X ----------------------------------------+----------------------------------- Reporter: AndreasVoellmy | Owner: Type: bug | Status: new Priority: normal | Component: libraries/base Version: 7.7 | Keywords: Os: MacOS X | Architecture: Unknown/Multiple Failure: Incorrect result at runtime | Blockedby: Blocking: | Related: ----------------------------------------+----------------------------------- Comment(by AndreasVoellmy): I added a patch to make the parallel io manager work the same way as the old io manager; namely, when a file is registered with the a kqueue-based IO manager and kevent returns EINVAL, then the manager simply calls the callback provided by the user for the event. This is a first step to an improved handling of this situation. Next step would be to register the event and callback with a manager that can actually handle the file appropriately. As discussed in the email thread with PHO, it seems that select is best for this. So to finish this, we should: 1. Implement a select-based backend. 2. Have the TimerManager use the select-based backend and export file registration commands from TimerManager. 3. Have Thread handle the fallback to the TimerManager when the preferred IO manager fails. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7773#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
