#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: | -------------------------------------+------------------------------------- Changes (by snowleopard): * cc: NeilMitchell (added) Comment: Thank for reporting. 45 seconds of doing nothing sounds strange, I'm not sure how/why this happened. Is this something you can reliably reproduce by `Ctrl-C`'ing the full build in the middle of building `libraries/base`? Zero build currently takes around 7 seconds on my machine. Neil was optimistic that we'll be able to substantially improve this, so I'm tagging him too. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15938#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
