Old remote alias still visible in git logs and gitk, how to delete?

I recently renamed a remote to a new alias and the old alias (and all its commits up until the point of renaming) is still visible in the logs and consequently gitk. Running

$ git remote show old-alias

obviously returns:

fatal: 'old-alias' does not appear to be a git repository

This is pretty annoying. How do I cleanly remove these references? Is it OK if I manually delete the 

.git/logs/refs/remotes/old-alias/
.git/refs/remotes/old-alias/

directories?

Edit:

Here is the git remote -v output:

origin  git@github.com:my-user/our-repo (fetch)
origin  git@github.com:my-user/our-repo (push)
upstream        git@github.com:upstream-user/our-repo (fetch)
upstream        git@github.com:upstream-user/our-repo (push)

Here is the git log --oneline --graph --decorate output:

Solution

  • The question here has a similar issue: Why is old name of git remote sill in .git/refs/remotes?. Following the advice there, I deleted the 

    .git/logs/refs/remotes/old-alias/
.git/refs/remotes/old-alias/

    directories manually. There are residual logs in .git/logs/HEAD and .git/logs/refs/heads/someotherbranch:

    ./logs/HEAD:14:6d8019... Ayberk Özgür <ayberk.ozgur@email.com> 1394819391 +0100   pull old-alias someotherbranch: Fast-forward
./logs/refs/heads/android:13:6d8019... Ayberk Özgür <ayberk.ozgur@email.com> 1394819391 +0100     pull old-alias someotherbranch: Fast-forward

    I don't exactly know if those are the only traces left of old-alias or whether they may be harmful. However, I haven't encountered any issues so far.
