#14097: -ddump-json doesn't interact as expected with -ddump-to-file -------------------------------------+------------------------------------- Reporter: mpickering | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: JSON 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 mpickering): The problem is that `dumpPrefix` is set in DriverPipeline but then this modified version of `DynFlags` is not propagated outwards and so it is not set at the time `jsonLogFinaliser` calls `dumpSDoc`. This means that `chooseDumpFile` fails as `dumpPrefix` is not set and the output is instead forwarded onto stdout. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14097#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
