#16253: Offer a shorthand for `--skip=_build/stage$n/compiler/.dependencies.mk` -------------------------------------+------------------------------------- Reporter: sgraf | Owner: (none) Type: task | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.6.3 (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 snowleopard): Simon: this is expected behaviour in this case. Dependency analysis of Haskell sources is performed on per package (not per file) basis, in one go. Whenever a single source file is changed, we invoke `ghc -M` on the whole package, which can take a while for a large package. This is how Make works too, but it often disables the tracking mechanism, which may lead to incorrect build results but is fast. Perhaps, we could/should switch to dependency analysis on the per-file basis (as we do with C sources), which would directly address this particular ticket without introducing yet another way to disable tracking. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/16253#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
