Here is the script I use to test with
REPO="file:///tmp/SVNuboot" REPO_PATH="/tmp/SVNuboot" GIT_REPO="/tmp/mygituboot" ORG_REPO="/usr/local/src/u-boot" rm -rf "$REPO_PATH" rm -rf "$GIT_REPO" svnadmin create "$REPO_PATH" svn mkdir -m "initial repo layout" "$REPO"/trunk "$REPO"/branches "$REPO"/tags mkdir -p "$GIT_REPO" cd "$GIT_REPO" git-svn init "$REPO"/trunk echo [user] >> .git/config echo name="jocke" >> .git/config echo email="Joakim.Tjernlund@transmode.se" >> .git/config git-svn fetch git checkout -b svn-branch remotes/git-svn git-fetch "$ORG_REPO" tmcu2:tmcu git-branch initial-uboot f5e0d03970409feb3c77ab0107d5dece6b7d45c9 git pull . initial-uboot # --squash makes one large commit. #git pull --squash . initial-uboot #cg-commit -m "merge up to f5e0d03970409feb3c77ab0107d5dece6b7d45c9"
# without --squash one gets a SVN repo with lots of small commits(2) git pull . initial-uboot git-svn commit -q remotes/git-svn..svn-branch
(2)
This fails currently with
git-svn commit -q remotes/git-svn..svn-branch
