Today I found myself needing to move some commits between two repositories. In general the best way to do this is by pulling changes from one into the other, but in this case the repositories did not have direct access to each other. Rather than copying an entire repository from one machine to another or mucking about with a pile of patches, we can save time by performing the sending and receiving sides of the network-enabled
git fetch command by hand.
In the source repository, add the changes we want to move to a bundle that we can copy to a USB stick:
% git bundle create changes.bundle master..mybranch Counting objects: 5, done. Delta compression using up to 4 threads. Compressing objects: 100% (3/3), done. Writing objects: 100% (3/3), 313 bytes, done. Total 3 (delta 2), reused 0 (delta 0) % cp changes.bundle /media/usbstick
In the destination repository, ensure that we have the commits necessary to use the bundle and then tell
git fetch to grab the changes from it:
% git bundle verify /media/usbstick/changes.bundle The bundle contains 1 ref 7a1d2087f10e6db33e6b4a28e2c427b65238a62c refs/heads/mybranch The bundle requires these 1 ref 6f5fced94ef76f1b46e259db72ad6fc39c49ba72 /media/usbstick/changes.bundle is okay % git fetch /media/usbstick/changes.bundle mybranch Receiving objects: 100% (3/3), done. Resolving deltas: 100% (2/2), completed with 2 local objects. From /media/usbstick/changes.bundle * branch mybranch -> FETCH_HEAD % git merge FETCH_HEAD Updating 6f5fced..7a1d208 Fast-forward README | 2 ++ 1 file changed, 2 insertions(+)
