#13152: Provide a mechanism to notify build system when .hi file is ready -------------------------------------+------------------------------------- Reporter: rwbarton | Owner: Type: feature request | Status: new Priority: normal | Milestone: 8.2.1 Component: Driver | Version: 8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by rwbarton): I'm not sure. What if the interface file already existed, and either (1) we checked that we don't need to recompile (in which we currently don't touch the interface file at all), or (2) we do need to recompile and write out a new interface file? Programming with inotify can be fiddly (for example, the man page says that it is possible for events to be lost), and I don't know whether we could reliably distinguish a new/unchanged-but-confirmed-valid interface file from a stale one. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13152#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
