[GHC] #8124: Possible leaks when using foreign export.
#8124: Possible leaks when using foreign export. ------------------------------+-------------------------------------------- Reporter: augustss | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Runtime | Version: 7.6.3 System | Operating System: Unknown/Multiple Keywords: | Type of failure: Runtime performance bug Architecture: | Test Case: Unknown/Multiple | Blocking: Difficulty: Unknown | Blocked By: | Related Tickets: | ------------------------------+-------------------------------------------- When a Haskell function exported with foreign export is called from outside Haskell a new Task may be allocated for it. There will be one Task allocated for each OS thread calling into Haskell (this happens in rts_lock()). This Task is, by design, never deallocated. This works fine with a small number of threads, but if the external caller generates a lot of threads that die the Haskell RTS will just get more and more Task objects that are never freed. The Task also contains a condition variable and a mutex, which incurs a HANDLE leak on Windows. I don't see an elegant fix to this, but the attached code remembers the OS thread for "incall" Task, and every so often (every 100 Tasks created) if will scan the Tasks looking for ones where the OS thread is dead, and remove these. The fix only works on Windows, I'm afraid. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8124 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

When destroying a thread, you need to know if it was ever used for GHC or incurr some overhead. As long as the dealloc is cheap and doesn't require you to have done the alloc, that's OK. 2. You need to know when the thread goes away. If you are using a thread pool library, that's often very tricky. In our particular case it's feasible. 3. If a thread dies unexpectedly the memory will be leaked. That's hopefully not a big issue in practice. So an explicit dealloc is OK for us, with the caveat that is must work successfully on a thread that was never used by GHC. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8124#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

The tricky bit is knowing when to do so - too eager and we penalize threads that are doing frequent in-calls, too lazy and we have the memory leak again. Perhaps just sweeping the table during a major GC would be good enough. Better might be to only free Tasks that have survived one major GC cycle without being used, but that's a bit more work. I'll look into this when I've got some time. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8124#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
