#9003: GHC eventlog: thread stop status codes modified (breaking ghc-events, threadscope, edentv) -------------------------------+------------------------------------------- Reporter: jberthold | Owner: simonmar Type: bug | Status: new Priority: normal | Milestone: 7.8.3 Component: Runtime | Version: 7.8.2 System | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Easy (less than 1 hour) Unknown/Multiple | Blocked By: Type of failure: Other | Related Tickets: Test Case: | Blocking: | -------------------------------+------------------------------------------- Comment (by ezyang): Here's another perspective: really this is just a bug in this function implementation: {{{ INLINE_HEADER void traceEventStopThread(Capability *cap STG_UNUSED,· StgTSO *tso STG_UNUSED,· StgThreadReturnCode status STG_UNUSED, StgWord32 info STG_UNUSED) { traceSchedEvent2(cap, EVENT_STOP_THREAD, tso, status, info); dtraceStopThread((EventCapNo)cap->no, (EventThreadID)tso->id, (EventThreadStatus)status, (EventThreadID)info); } }}} We shouldn't cast from `StgThreadReturnCode` to `EventThreadStatus`, really we should have some translation function from one to the other (coded in terms of the constants, so updating `Constants.h` works automatically). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9003#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
