#15938: Hadrian's recompilation check is extremely slow -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.8.1 Component: Build System | Version: 8.6.2 (Hadrian) | Resolution: | Keywords: 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 NeilMitchell): Shake records cached oracles immediately and even if the build fails (but not if the parsing of the metadata fails, as you might expect). I'd treat the pause and the slow rebuild as entirely separate issues, since they likely have different causes. Of these, slow rebuild is the easiest one to reproduce - generally you shouldn't be running any command line tools during a rebuild, and if you do, you failed to cache something properly. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15938#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
