![]() The meaning of a signoff depends on the project to which you’re committing. See also git-fmt-merge-msgĭo not list one-line descriptions from the actual commits being mergedĪdd a Signed-off-by trailer by the committer at the end of the commit log message. In addition to branch names, populate the log message with one-line descriptions from at most actual commits that are being merged. Is useful to countermand both commit.gpgSign configuration variable, and earlier -gpg-sign The keyid argument is optional and defaults to the committer identity if specified, it must be stuck to the option without a space When not possible, refuse to merge and exit with a non-zero status Resolve the merge as a fast-forward when possible. When not possible (when the merged-in history is not a descendant of the current history), create a merge commitĬreate a merge commit in all cases, even when the merge could instead be resolved as a fast-forward When possible resolve the merge as a fast-forward (only update the branch pointer to match the merged branch do not create a merge commit). In addition, if the is given a value of scissors, scissors will be appended to MERGE_MSG before being passed on to the commit machinery in the case of a merge conflict This option determines how the merge message will be cleaned up before committing. The -edit (or -e) option is still useful if you are giving a draft message with the -m option from the command line and want to edit it in the editor The -no-edit option can be used to accept the auto-generated message (this is generally discouraged). Invoke an editor before committing successful mechanical merge to further edit the auto-generated merge message, so that the user can explain and justify the merge Perform the merge and stop just before creating a merge commit, to give the user a chance to inspect and further tweak the merge result before committing This option can be used to override -no-commit If you are interested in squashing the commits manually, but don’t know how, check out my previous post about squashing.Perform the merge and commit the result. You can read more about this feature in GitHub’s documentation and GitLab’s documentation. But it’s configured on a per-repository basis, so if you don’t control the repository, you might have to ask your development team’s administrator to turn on the feature. It’s worth mentioning that both GitHub and GitLab allows you to do the fast-forward (and squash) merge on it’s UI. You may want to do one last test before pushing" ![]() Let’s see how to do this with an example:ĬURRBRANCH=$(git rev-parse -abbrev-ref HEAD)Įcho "Merging the change from $CURRBRANCH to master."Įcho "Rebasing branch $CURRBRANCH to latest master"Įcho "Checking out to master and pull" & \Įcho "Merging the change from $CURRBRANCH to master." & \Įcho "DONE. So if someone pushes to master and you did a git pull on your local master, you need to do a rebase on your feature branch before using -ff-only merge. But it only works if there is not new commits in master but not in your feature branch, otherwise it will fail with a warning. This option will cleanly append your commits to master, without creating a merge commit. What you are looking for is the opposite: -ff-only ( ff stands for fast-forward). Under the hood, GitHub and GitLab’s “merge” button uses the -no-ff option, which will force create a merge commit. How can you develop in branches but merge them back to master without a merge commit? Everyone is suppose to push directly to master, and maintain a linear history. More importantly, some development teams don’t use pull request or merge requests at all. The commits on your branch might interlace with other people’s commits. So if multiple people merged multiple branches, all of them will be mixed up. If you look at GitHub’s commit history, you’ll notice that the UI shows a linear history, and the commits are ordered by the time they were pushed. If we now create a pull request for our branch, and get merged, we’ll see a new merge commit called “Merge branch ‘new-feature’” At the same time someone pushed another commit called “Other’s feature” onto the master branch. Let’s assume we branch out a feature branch called “new-feature” from the master branch, and pushed a commit called “Finished my new feature”. That means your feature branch will be merged into the master by creating a new commit, and both the feature and master branch will be kept.
