Subject: [PATCH v4 5/7] push: add an advice on unqualified <dst> push
Date: Tue, 13 Nov 2018 19:52:43 +0000 [thread overview]
Message-ID: <20181113195245.14296-6-avarab@gmail.com> (raw)
In-Reply-To: <20181026230741.23321-1-avarab@gmail.com>
Add an advice to the recently improved error message added in
f8aae12034 ("push: allow unqualified dest refspecs to DWIM",
2008-04-23).
Now with advice.pushUnqualifiedRefName=true (on by default) we show a
hint about how to proceed:
$ ./git-push avar v2.19.0^{commit}:newbranch -n
error: The destination you provided is not a full refname (i.e.,
starting with "refs/"). We tried to guess what you meant by:
- Looking for a ref that matches 'newbranch' on the remote side.
- Checking if the <src> being pushed ('v2.19.0^{commit}')
is a ref in "refs/{heads,tags}/". If so we add a corresponding
refs/{heads,tags}/ prefix on the remote side.
Neither worked, so we gave up. You must fully qualify the ref.
hint: The <src> part of the refspec is a commit object.
hint: Did you mean to create a new branch by pushing to
hint: 'v2.19.0^{commit}:refs/heads/newbranch'?
error: failed to push some refs to 'git@github.com:avar/git.git'
When trying to push a tag, tree or a blob we suggest that perhaps the
user meant to push them to refs/tags/ instead.
The if/else duplication for all of OBJ_{COMMIT,TAG,TREE,BLOB} is
unfortunate, but is required to correctly mark the messages for
translation. See the discussion in
<87r2gxebsi.fsf@evledraar.gmail.com> about that.
