#13630: ByteString pinned memory can be leaky -------------------------------------+------------------------------------- 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: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by duncan): I've been wanting to switch to unpinned for ByteString for years, but it's a lot of work. It'd mean fixing up lots of other libs that use ByteString internals and it also requires a solution for the mmap'd ByteString use case (which does have solutions but it's still more work and may need some RTS extensions to be able to have an mmaped ByteArray# that unmaps when it's collected). As a workaround I often recommend people use ShortByteString, which is part of the bytestring package and uses unpinned memory. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13630#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
