A strange request, I admit...
We have a project that is currently managed in Bazaar, but was previously stored in Subversion. However, rather that copying the history across, the previous developers took a single export of the SVN repo and started a brand-new BZR repo.
Thus, we have the following:
SVN: A-B-C-D
BZR: E-F-G-H
And what I want is:
GIT: A-B-C-D-E-D-G-H
Thanks
Probably easiest with git filter-branch. In fact, this is one of the examples in the filter-branch documentation:
To set a commit (which typically is at the tip of another history) to be the parent of the current initial commit, in order to paste the other history behind the current history:
git filter-branch --parent-filter 'sed "s/^\$/-p <graft-id>/"' HEAD
So here <graft-id> is your commit D, assuming you are working from a branch consisting of the BZR commits E to H. So I assume you've used migration tools to get both the svn and bzr histories into git, and imported them as separate branches into a single repository.
