Git error The branch x is not fully merged

Question

Here are the commands I used from the master branch git branch experiment git checkout experiment  Then I made some changes to my files  committed the changes  and pushed the new branch to GitHub  git commit   -m  changed files  git push -u origin experiment  Later on I decided to merge my experiment branch into the master branch  git checkout master git merge experiment  Finally I pushed the changes to GitHub  git push -u origin master  All went well until I tried deleting my experiment branch using git branch -d experiment  I got the error message   error  The branch  experiment  is not fully merged  If you are sure you want to delete it  run  git branch -D experiment    I m a bit new to git  and I don t know how much more I could possibly merge the two branches  What am I missing here

I did not have the upstream branch on my local git   I had created a local branch from master  git checkout -b mybranch    I created a branch with bitbucket GUI on the upstream git and pushed my local branch  mybranch  to that upstream branch   Once I did a git fetch on my local git to retrieve the upstream branch  I could do a git branch -d mybranch

Git is warning that you might lose history by deleting this branch  Even though it would not actually delete any commits right away  some or all of the commits on the branch would become unreachable if they are not part of some other branch as well   For the branch experiment to be    fully merged    into another branch  its tip commit must be an ancestor of the other branch   s tip  making the commits in experiment a subset of the other branch  This makes it safe to delete experiment  since all its commits will remain part of the repository history via the other branch  It must be    fully    merged  because it may have been merged several times already  but now have commits added since the last merge that are not contained in the other branch   Git doesn   t check every other branch in the repository  though  just two    The current branch  HEAD  The upstream branch  if there is one   The    upstream branch    for experiment  as in your case  is probably origin experiment  If experiment is fully merged in the current branch  then Git deletes it with no complaint  If it is not  but it is fully merged in its upstream branch  then Git proceeds with a warning seeming like   warning  deleting branch  experiment  that has been merged to  refs remotes origin experiment   but not yet merged to HEAD  Deleted branch experiment  was xxxxxxxx     Where xxxxxxxx indicates a commit id  Being fully merged in its upstream indicates that the commits in experiment have been pushed to the origin repository  so that even if you lose them here  they may at least be saved elsewhere   Since Git doesn   t check other branches  it may be safe to delete a branch because you know it is fully merged into another one  you can do this with the -D option as indicated  or switch to that branch first and let Git confirm the fully merged status for you

Note Wording changed in response to the commments  Thanks  slekse That is not an error  it is a warning  It means the branch you are about to delete contains commits that are not reachable from any of  its upstream branch  or HEAD  currently checked out revision   In other words  when you might lose commits    In practice it means that you probably amended  rebased or filtered commits and they don t seem identical  Therefore you could avoid the warning by checking out a branch that does contain the commits that you re about un-reference by deleting that other branch    You will want to verify that you in fact aren t missing any vital commits  git log --graph --left-right --cherry-pick --oneline master   experiment  This will give you a list of any nonshared between the branches  In case you are curious  there might be a difference without --cherry-pick and this difference could well be the reason for the warning you get   --cherry-pick Omit any commit that introduces the same change as another commit on the  quot other side quot  when the set of commits are limited with symmetric difference  For example  if you have two branches  A and B  a usual way to list all commits on only one side of them is with --left-right  like the example above in the description of that option  It however shows the commits that were cherry-picked from the other branch  for example   quot 3rd on b quot  may be cherry-picked from branch A   With this option  such pairs of commits are excluded from the output       they re really only garbage collected after a while  by default  Also  the git-branch command does not check the revision tree of all branches  The warning is there to avoid obvious mistakes      My preference here is to just force the deletion instead  but you might want to have the extra reassurance

I believe the flag --force is what you are really looking for  Just use git branch -d --force  lt branch name gt  to delete the branch forcibly

I had this happen to me today  as I was merging my very first feature branch back into master  As some said in a thread elsewhere on SO  the trick was switching back to master before trying to delete the branch  Once in back in master  git was happy to delete the branch without any warnings

If you made a merge on Github and are seeing the error below  You need to pull  fetch and commit  the changes from the remote server before it will recognize the merge on your local  After doing this  Git will allow you to delete the branch without giving you the error  error  The branch  x  is not fully merged  If you are sure you want to delete it  run  git branch -D  x

As Drew Taylor pointed out  branch deletion with -d only considers the current HEAD in determining if the branch is  fully merged    It will complain even if the branch is merged with some other branch   The error message could definitely be clearer in this regard    You can either checkout the merged branch before deleting  or just use git branch -D   The capital -D will override the check entirely

You can simply figure out        git log --cherry master   experimental   --cherry option is a synonym for --right-only --cherry-mark --no-merges  git-log man page said      it s useful to limit the output to the commits on our side and mark those that have been applied to the other side of a forked history with git log --cherry upstream   mybranch  similar to git cherry upstream mybranch    FYI  --cherry-pick omits equivalent commits but --cherry-marks doesn t  It s useful to find rebase and force updated changes between upstream and co-working public branch
