Hello all,
Today Opera Software released the "Git-splitter", a small tool for
sub-modularizing code in a git repo, with complete commit history,
under
the Apache 2.0 license.
It's functionality is similar to "git-subtree", but also include a
command
for reversing the process.
Is there something keeping you technically from adding a join command
to
git-subtree?
Probably not, but within the process I was working I did not want to
merge
the branch with the recreated history for that path into the existing
codebase (I don't like duplicate histories) so I used rebasing to move
the
new commits over, instead, and therefore did not need a join command.
Feel free to add a join command, if you want one.
Im sorry, but that was a total misunderstanding. You said git-splitter
is like git-subtree but adds a command for reversing the process. My
question was: What kept you from adding that to git-subtree (rather than
redoing stiff that git-subtree does)?
I just assumed that reversing the process of splitting must be joining.
It may very well be that git-splitter does things differently, i.e. that
there are more differences than just added functionality (compared to
git-subtree), but that is not clear from the announcement.
The split command will create a new repository for all files foo in a
folder (path/foo) and their commit history.
The replant command reverses that process, re-adding the path prefix for
each file. It may be possible to extend that process into one that
automatically reintegrates the new commits in the original history, but I
never had time to complete that work.
I did originally add the "replant" functionality into my version of the
git-subtree script, but given the number of commits in the original
repository, git-subtree turned out to be inefficient, due to the use of
temporary files (tens of thousands of files IIRC).
Those problems led to my development of git-splitter in Python (bypassing
the problem of temporary files), but just including the functionality I
needed, join was not one of those functions.
The code is hosted on GitHub:

We have announced the release as part of another announcement of
released
code at the Opera Security Group home page:
