#13945: 'ghc-pkg update' fails due to bad file descriptor error ---------------------------------+---------------------------------------- Reporter: mpickering | Owner: (none) Type: bug | Status: patch Priority: high | Milestone: 8.2.2 Component: Compiler | Version: 8.2.1-rc3 Resolution: | Keywords: Operating System: Linux | Architecture: Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D3897 Wiki Page: | ---------------------------------+---------------------------------------- Changes (by bgamari): * status: new => patch * differential: => Phab:D3897 Comment: So this is problematic: `lockPackageDb` first tries to open (and then exclusively lock) the lockfile as read-only to account for the possibility that we are opening a global package database for which we only have read access. However, NFS does not allow this as mentioned above. I believe Phab:D3897 is one possible fix. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13945#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
