git cheat sheet for Core development

This is a short list of commands. If you are not familiar with the workflow yet, make sure you follow the link at the beginning of each section and read the detailed description.

The following commands assume you are in the working directory of the TYPO3 core repository.

git clone

Clone latest master into current directory:

git clone git:// .


Details: Setting up your Git environment

Set username and email in repository configuration (default is --local = in current repo .git/config):

git config "Your Name"
git config ""

If your username and email is the same for all your projects, set it globally (in home config ~/.gitconfig, active for all git repos):

git config --global "Your Name"
git config --global ""

Set autosetuprebase:

git config branch.autosetuprebase remote

Copy commit-msg hook:

cp Build/git-hooks/commit-msg .git/hooks/commit-msg

Push to gerrit

  • replace <YOUR_TYPO3_USERNAME> with your Gerrit / user name!
git config url."ssh://<YOUR_TYPO3_USERNAME>".pushInsteadOf git://

Optional: Set a commit message template:

git config commit.template ~/.gitmessage.txt

This command uses the file ~/.gitmessage.txt as git message template. For additional information about how to set up a proper commit message see Commit Template

Show current configuration:

git config -l

Workflow - common commands

For details see Create & submit a patch

Reset repo to last remote commit in (remote) master:

git reset --hard origin/master && git pull origin master

Stage and commit all changes:

git commit -a

Is the same as:

git add .
git commit

Stage and commit all changes to already existing commit:

git commit -a --amend

Push changes to remote master on gerrit (default method):

git push origin HEAD:refs/publish/master

Workflow - drafts

Push changes to remote master on gerrit as draft:

git push origin HEAD:refs/drafts/master

When pushing as draft, the pushed patch will only be visible to you and those who you add as a reviewer. It also does not start any automated tests or builds on the TYPO3 testing infrastructure.

Workflow -other branches

Show all branches:

git branch -a

Checkout 8.7 branch:

git checkout TYPO3_8-7


Pushing to a branch other than master only makes sense if the bug only exists on that branch and does not exist on master. Backporting of a fix to a branch is done by the core team member who merges the original fix to the master branch.

Long story short: In most cases, push to master. The rest is being taken care of when time is right.

Push 8.7 branch:

git push origin HEAD:refs/publish/TYPO3_8-7

Push 7.6 branch:

git push origin HEAD:refs/publish/TYPO3_7-6

Workflow - commit msg

Details: Commit Message rules for TYPO3 CMS

Example commit message for a bugfix:

[BUGFIX] Subject line


Resolves: #12345
Releases: master, 8.7

Other keywords:

  • subject < 52 chars
  • other lines <= 72 chars

Workflow - Undoing / fixing things

Throw away all changes since last commit:

git reset HEAD --hard

Unstage a file (remove file from index, but keep in working dir):

git reset <path>

Change author for last commit:

git commit --amend --author "Some Name <some@email>"

Squash last 2 commits:

This is very handy, in case you accidentally created a new commit instead of adding to an existing commit (with git commit --amend).

  • All changes have been committed or stashed
  • Run the following command:
git rebase -i HEAD~2
  • In the editor, replace 'pick' with 'squash' in the line describing the latest commit
