This could be part of GHC's installation script possibly, or maybe a feature of cabal install. cabal can check the installed packages for the previous version of GHC and "cabal install" them. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/199 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

It goes through the old ghc package.conf (well actually, a separate set of files that each gentoo ebuild installs) and rebuilds all the available packages for the new ghc. We'd have to do it in a rather sloppy way since we do not know that each registered package was actually installed by cabal-install or is available from hackage. Also, many packages would fail to build with new ghc so we'd want to not stop when the first package fails but produce a report at the end saying which old packages were unavailable or failed to rebuild. Such a sloppy mode, producing a report would also be very useful for general hackage QA. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/199#comment:1 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

I suppose this ticket hasn't been resolved yet. I would be interested in writing a patch for it, but would need to know whether my approach described in http://www.haskell.org/pipermail/cabal-devel/2009-February/004800.html is the right way to go. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/199#comment:5 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

It means that moving between compilers is easy. It's not likely that you want some things in one but not another. What is more likely is that there are some things that simply cannot be installed with an older version. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/199#comment:7 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

that moving between compilers is easy. It's not likely that you want some things in one but not another. What is more likely is that there are some things that simply cannot be installed with an older version. I agree with that; if different world-files are really necessary, you can always (albeit manually) select them with the --world-file flag. Btw: Maybe adding a "--oneshot" install-flag makes sense for installing without updating world. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/199#comment:8 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects

Whenever you install a package, an entry is added to the world-file, storing the specified package-name, package-version, and user flags. For example, the entry generated by {{{ # cabal install stm-io-hooks --flags="-debug" }}} looks like this: {{{ stm-io-hooks -any --flags="-debug" }}} The requires dependencies of a packge, however, are not recorded in the world file, only the packages explicitly requested by the user. To rebuild all previously installed packages (e.g. on updating GHC), use {{{ # cabal install world }}} The previous version of this patch supported the "cabal upgrade world" command, which is now disabled until "cabal upgrade" is fixed. -- Ticket URL: http://hackage.haskell.org/trac/hackage/ticket/199#comment:10 Hackage http://haskell.org/cabal/ Hackage: Cabal and related projects
