#14381: Consider making ghc-pkg fill in abi-depends based on depends -------------------------------------+------------------------------------- Reporter: ezyang | Owner: tdammers Type: bug | Status: new Priority: highest | Milestone: 8.4.2 Component: ghc-pkg | Version: 8.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4159 Wiki Page: | -------------------------------------+------------------------------------- Comment (by tdammers): As discussed in person: this can produce a lot of warnings that may not be very useful in practice. `ghc-pkg` is essentially always doing the "right thing" here, overriding declared dependencies with inferred ones, and we are more confident on the inferred ones than the declared ones (the latter essentially being subject to human error). The way it works now, we will also see a lot of unnecessary warnings: when the declared and inferred dependencies agree, `ghc-pkg` will still do the overriding and issue a warning, but that warning will be pointless, because we aren't making any effective changes. Because of this, we will only raise this warning in debug mode, which should also take care of the now-failing tests. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14381#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
