git shows old deleted branches in zsh TAB completion

Question

I apologize if this is a duplicate, but I don't know if this is a git "feature" or zsh, but I have a TON of delete branches that have been deleted stored somewhere if I tab over.

I have tried prune and that appears to not be doing want I intend.

The only branches I have locally are:

master
development
fix/root-cleanup

Answer 1

Apparently, the autocomplete tab was showing all the names of remote branches I had not done housekeeping on.

Found clues reading this blog post.

I was fixated on local and did not even consider if the plugin was pulling from the remote branches.

What's frustrating is that as in the screenshot all the branches without origin/ were not local and not there. As soon as I started to delete the remote branches these ones disappeared as well.

Answer 2

Maybe installing a oh-my-zsh plugin like diazod/git-prune would help apply the various git prune aliases.

That in turn should reduce the number of branches considerably.

Note that, with Git 2.28 (Q3 2020), "git prune" has been added to the completion (in contrib/), which could be typed by end-users from the command line.

bash-completion: add git-prune into bash completion

Sometimes git would suggest the user to run git prune when there are too many unreachable loose objects.
It's more user-friendly if we add git prune into bash completion.
