Subject: [PATCH] branch: description for non-existent branch errors
Date: Fri, 23 Sep 2022 00:37:42 +0200 [thread overview]
Message-ID: <c333cc4b-12a1-82b6-0961-1c42080dad15@gmail.com> (raw)
When the repository does not yet has commits, some errors describe that
there is no branch:
$ git init -b first
$ git --edit-description first
fatal: branch 'first' does not exist
$ git --set-upstream-to=upstream
fatal: branch 'first' does not exist
$ git branch -c second
error: refname refs/heads/first not found
fatal: Branch copy failed
That "first" branch is unborn but to say it doesn't exists is confusing.
Options "-c" (copy) and "-m" (rename) show the same error when the
origin branch doesn't exists:
$ git branch -c non-existent-branch second
error: refname refs/heads/non-existent-branch not found
fatal: Branch copy failed
$ git branch -m non-existent-branch second
error: refname refs/heads/non-existent-branch not found
fatal: Branch rename failed
Note that "--edit-description" without an explicit argument is already
considering the _empty repository_ circumstance in its error. Also note
that "-m" on the initial branch it is an allowed operation.
This commit makes the error descriptions for those branch operations
with unborn or non-existent branches, more informative.
This is the result of the change:
$ git init -b first
$ git --edit-description first
fatal: No commit on branch 'first' yet.
$ git --set-upstream-to=upstream
fatal: No commit on branch 'first' yet.
$ git -c second
fatal: No commit on branch 'first' yet.
$ git [-c/-m] non-existent-branch second
fatal: No branch named 'non-existent-branch'.

Hi all.
I would appreciate some guidance here.
This patch is based on master but there is already in 'seen' a patch
submitted for 'branch' that produces conflicts with this. I don't know
if it is more convenient to submit this patch based on 'seen'
considering that.
I submitted that other patch too and prefer to keep the changes separate
but maybe it's better not to and do a rollup with this on that other
patch.. I don't know how disturbing it is to submit a new patch when it
is "waiting for review".
Another approach?
Thank you.
Un saludo.
