#9133: Improve parser error reporting in `ghc-pkg` ------------------------------------+------------------------------------- Reporter: hvr | Owner: Type: task | Status: new Priority: normal | Milestone: 7.10.1 Component: ghc-pkg | Version: 7.8.2 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- Here's what I was confronted recently due to a broken sandbox environment: {{{ $ cabal info parsec cabal: ghc-pkg: Data.Binary.Get.runGet at position 9583: demandInput: not enough bytes }}} The main problem is that this message is not very helpful (other than telling that `ghc-pkg` wasn't able to do something). Duncan told me, that the recent `binary` API now provides better facilities for error reporting. That could be used to improve the UI of `ghc-pkg` when reporting errors. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9133 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
