Hi, I'm trying to make sense of the git fast-import manual page. This is what it reads, as of git 1.7.8.3, from Debian unstable: Omitting the from command in the first commit of a new branch will cause fast-import to create that commit with no ancestor. This tends to be desired only for the initial commit of a project. If the frontend creates all files from scratch when making a new branch, a merge command may be used instead of from to start the commit with an empty tree. Omitting the from command on existing branches is usually desired, as the current commit on that branch is automatically assumed to be the first ancestor of the new commit. When I do create a commit on a given branch with a stream like: commit refs/heads/branch author ... committer ... data <<EOF Commit message EOF deleteall All I get is this warning: warning: Not updating refs/heads/branch (new tip new_sha1 does not contain old_sha1) And the branch only has one commit, which is the one I just created. On the other hand, if I add a "from" instruction in the above stream, I have the expected branch history. Arguably, this may be related to my use of deleteall, but nothing in the deleteall description suggests this would happen. Is it an expected behaviour and a lack of proper documentation, or is it a bug in git fast-import ?
