git-stitch-repo - Stitch several git repositories into a git-fast-import stream
git-stitch-repo repo1 repo2:dir2 ...
git-stitch-repo will process the output of
git-fast-export --all --date-orderon the git repositories given on the command-line, and create a stream suitable for git-fast-import that will create a new repository containing all the commits in a new commit tree that respects the history of all the source repositories.
Imagine we have two repositories A and B that we want to stitch into a repository C so that all the files from A are in subdirectory A and all the files from B are in subdirectory B.
topic ' ,master A3---A5 / / A1---A2---A4
Branch master points to A5 and branch topic points to A3.
Repository B: ,topic ,master B3---B5---B7---B8 / / B1---B2---B4---B6
Branch master points to B8 and branch topic points to B5.
The C repository should preserve chronology, commit relationships and branches as much as possible, while giving the impression that the directories A & B did live side-by-side all the time.
Assuming additional timestamps not shown on the above graphs, git-stitch-repo will produce a git-fast-import stream that will create the following history:
,topic ,master A3---B3---A5---B5---B7---B8 / / / A1---B1---A2---B2---A4---B4--------B6
Note that the current result is slightly buggy, since A5 wasn't on the topic branch in the original graph for A.
