I want to find out who created a branch.
I am sort of able to do so with:
git branch -a | xargs -L 1 bash -c 'echo "$1 `git log --pretty=format:"%H %an" $1^..$1`"' _
However, this returns the last committer per branch, not necessarily the person who created the branch.
A branch is nothing but a commit pointer. As such, it doesn't track metadata like "who created me." See for yourself. Try cat .git/refs/heads/<branch> in your repository.
That written, if you're really into tracking this information in your repository, check out branch descriptions. They allow you to attach arbitrary metadata to branches, locally at least.
Also DarVar's answer below is a very clever way to get at this information.
List Remote Git Branches By Author sorted by committerdate:
git for-each-ref --format='%(committerdate) %09 %(authorname) %09 %(refname)' | sort -k5n -k2M -k3n -k4n
I tweaked the above answers by using the --sort flag and adding some color/formatting.
git for-each-ref --format='%(color:cyan)%(authordate:format:%m/%d/%Y %I:%M %p) %(align:25,left)%(color:yellow)%(authorname)%(end) %(color:reset)%(refname:strip=3)' --sort=authordate refs/remotes
Adding to https://stackoverflow.com/a/19135644/2917986
git for-each-ref --format='%(committerdate) %09 %(authorname) %09 %(refname)' | sort -k5n -k2M -k3n -k4n | awk '{print $7 $8}'
P.S. We used awk to pretty print the author & the remote branch
git for-each-ref --format='%(authorname) %09 -%(refname)' | sort
You can find out who created a branch in your local repository by
git reflog --format=full
Example output:
commit e1dd940
Reflog: HEAD@{0} (a <a@none>)
Reflog message: checkout: moving from master to b2
Author: b <b.none>
Commit: b <b.none>
(...)
But this is probably useless as typically on your local repository only you create branches.
The information is stored at ./.git/logs/refs/heads/branch. Example content:
0000000000000000000000000000000000000000 e1dd9409c4ba60c28ad9e7e8a4b4c5ed783ba69b a <a@none> 1438788420 +0200 branch: Created from HEAD
The last commit in this example was from user "b" while the branch "b2" was created by user "a". If you change your username you can verify that git reflog takes the information from the log and does not use the local user.
I don't know about any possibility to transmit that local log information to a central repository.
assuming:
- branch was made from
master - hasn't been merged to
masteryet
git log --format="%ae %an" master..<HERE_COMES_BRANCH_NAME> | tail -1
I know this is not entirely the scope of the question, but if you find the need to filter only commits by a specific author, you can always pipe to grep :)
# lists all commits in chronological order that
# belong to the github account with
# username `MY_GITHUB_USERNAME` (obviously you
# would want to replace that with your github username,
# or the username you are trying to filter by)
git for-each-ref --format='%(committerdate) %09 %(authorname) %09 %(refname)' | sort -committerdate | grep 'MY_GITHUB_USERNAME'
happy coding! :)
As far as I know, you may see if you are the creator of a branch only. This is indicated by the first row in .git/ref/heads/<branch>. If it ends with "Created from HEAD" you are the creator.
