Hi,

It's been a while since the last StGit release, mainly because it had
all the features I needed (well, a few bug fixes since then that
should have been released).

Anyway, I recently had to work in a team on a Linux kernel project and
because our patches were interdependent, we decided that the best
approach is to share the same branch on a common repository. But we
also had to keep patches relatively clean for pushing upstream
(http://git.kernel.org/?p=linux/kernel/git/cmarinas/linux-2.6-cm.git;a=shortlog;h=refs/heads/arm-lpae).

To make merging between us easier, we went with using plain Git and
instead of refreshing patches (the StGit way) we used new commits with
the "fixup!" prefix. At some point one of us did a "git rebase -i
--autosquash" to bring the fixups into patches (and some other
clean-up, patch reordering). It all went well but I missed StGit in
this workflow.

What's missing in StGit is easy interworking with git commands like
commit and rebase. This could be fixed by changing (reducing) the
StGit metada to rely more on what Git already provides. The main
visible effect would be patch names becoming automatic, similar to
those generated by "stg uncommit" but without the possibility of
renaming. The corresponding --name options and the "new" and "rename"
commands would also disappear ("new" can be replaced by either "git
commit" or an "stg commit" alias).

The base of the stack is no longer maintained by StGit but determined
as the common ancestor between the current branch and a
parent/upstream branch (maybe defaulting to origin/master). All the
commits from the common ancestor to HEAD are considered applied
patches.

The unapplied/popped patches (commits) could be linked into a separate
refs/heads/<branch>.unapplied. The refs/<branch>/patches/<patch-name>
are no longer created since refs/heads/* files can reach any of the
applied or unapplied patches. The standard Git reflog can be used for
undo information (though not infinite undo).

Any thoughts? I don't want to start implementing this if people find
the UI changes annoying.

Thanks,

Catalin
