#10529: hpc: Improve error messages in readMix -------------------------------------+------------------------------------- Reporter: nh2 | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Code | Version: 7.10.1 Coverage | Operating System: Unknown/Multiple Keywords: | Type of failure: None/Unknown Architecture: | Blocked By: Unknown/Multiple | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- See https://hackage.haskell.org/package/hpc-0.6.0.2/docs/src/Trace-Hpc- Mix.html#readMix The generic `error $ "can not find " ++ modName ++ " in " ++ show dirNames` error message is used for all kinds of cases, for example when `h == tixModuleHash tix` isn't true. It would be very helpful if the error message could be specific for these cases (e.g. "hashes don't agree") instead of being a catch-all for all `Nothing`s. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10529 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
