#15555: Finish separating the stable name and stable pointer tables -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: task | Status: new Priority: normal | Milestone: 8.8.1 Component: Runtime | Version: 8.4.3 System | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- The stable name table and stable pointer table are both implemented in `rts/Stable.c`, with their code interleaved. As far as I can tell, they basically don't share ''anything''—or at least anything that they actually ''should''. They ''do'' share a mutex, which smells like a terrible idea. Doesn't that just introduce contention between `StableName` and `StablePtr` operations in different threads? They also share an initialization function, `initStableTables`, that appears to allocate both a stable name table and a stable pointer table as soon as either of them is needed. Unless I'm missing something, there's no point whatsoever in doing that. So I think we should actually divide `Stable.c` into `StableName.c` and `StablePtr.c` and give each its own mutex. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15555 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
