Hello GHC Devs! In order to not drag this out any longer, I'll completing the submodule conversion in the next few hours by converting the remaining sub-repo packages into proper submodules. This is represents phase 1 of the reorganization (phase 2 comprises officially transitioning the push-urls of *some* the packages to github.com/haskell as happened with haddock). However, this phase 1 is important to get done early (ideally half a year ago) in order to make 'ghc-complete' bit more redundant (I hope Joachim doesn't mind... :-) ) and allow to properly 'git bisect' as far back as possible into the past. While the workflow changes[1] to additionally have the sub-repo change also registed in ghc.git, practically, this should affect only a minority of you, as the remaining packages (see list at the bottom of this mail) to be converted into submodules are modified *very* seldom. This will be similiar to the conversion of haddock.git into a proper submodule of which you read up in * http://permalink.gmane.org/gmane.comp.lang.haskell.ghc.devel/4049 * http://permalink.gmane.org/gmane.comp.lang.haskell.ghc.devel/4072 * http://permalink.gmane.org/gmane.comp.lang.haskell.ghc.devel/4077 List of packages converted into proper submodules: * libffi-tarballs libffi-tarballs.git * utils/hsc2hs hsc2hs.git * libraries/array packages/array.git * libraries/deepseq packages/deepseq.git * libraries/directory packages/directory.git * libraries/filepath packages/filepath.git * libraries/haskell98 packages/haskell98.git * libraries/haskell2010 packages/haskell2010.git * libraries/hoopl packages/hoopl.git * libraries/hpc packages/hpc.git * libraries/old-locale packages/old-locale.git * libraries/old-time packages/old-time.git * libraries/process packages/process.git * libraries/unix packages/unix.git * nofib nofib.git * libraries/parallel packages/parallel.git * libraries/stm packages/stm.git * libraries/dph packages/dph.git Ideally, you won't have any outstanding changes in those repos (hint, hint!) to make the transition for your GHC clones easier. I'll follow up with more specific instructions as soon as I've pushed the changes. N.B.: ghc-tarballs will *not* become a submodule, as it would impose a non-neglible cost on everyone, not only the developers on windows and, moreover, the plan is to turn ghc-tarballs into a scripted download (or maybe something git-annex based) as Git is not really suited for such large blobs.
