git-merge --squash
Some people tend to do many little commits on a topic branch, recording all the trials and errors, and when the topic is reasonably cooked well, would want to record the net effect of the series as one commit on top of the mainline, removing the cruft from the history. The topic is then abandoned or forked off again from that point at the mainline. The barebone porcelainish that comes with core git tools does not officially support such operation, but you can fake it by using "git pull --no-merge" when such a topic branch is not a strict superset of the mainline, like this: git checkout mainline git pull --no-commit . that-topic-branch : fix conflicts if any rm -f .git/MERGE_HEAD git commit -a -m 'consolidated commit log message' git branch -f that-topic-branch ;# now fully merged This however does not work when the topic branch is a fast forward of the mainline, because normal "git pull" will never create a merge commit in such a case, and there is nothing special --no-commit could do to begin with. This patch introduces a new option, --squash, to support such a workflow officially in both fast-forward case and true merge case. The user-level operation would be the same in both cases: git checkout mainline git pull --squash . that-topic-branch : fix conflicts if any -- naturally, there would be : no conflict if fast forward. git commit -a -m 'consolidated commit log message' git branch -f that-topic-branch ;# now fully merged When the current branch is already up-to-date with respect to the other branch, there truly is nothing to do, so the new option does not have any effect. This was brought up in #git IRC channel recently. Signed-off-by: Junio C Hamano <junkio@cox.net>
