Subject: [PATCH v2 2/2] remote.c: fix handling of %(push:remoteref)
Date: Tue, 3 Mar 2020 17:12:23 +0100 [thread overview]
Message-ID: <20200303161223.1870298-3-damien.olivier.robert+git@gmail.com> (raw)
In-Reply-To: <20200303161223.1870298-1-damien.olivier.robert+git@gmail.com>
Looking at the value of %(push:remoteref) only handles the case when an
explicit push refspec is passed. But it does not handle the fallback
cases of looking at the configuration value of `push.default`.
In particular, doing something like
git config push.default current
git for-each-ref --format='%(push)'
git for-each-ref --format='%(push:remoteref)'
prints a useful tracking ref for the first for-each-ref, but an empty
string for the second.
Since the intention of %(push:remoteref), from 9700fae5ee (for-each-ref:
let upstream/push report the remote ref name) is to get exactly which
branch `git push` will push to, even in the fallback cases, fix this.
To get the meaning of %(push:remoteref), `ref-filter.c` calls
`remote_ref_for_branch`. We simply add a new static helper function,
`branch_get_push_remoteref` that follows the logic of
`branch_get_push_1`, and call it from `remote_ref_for_branch`.
We also update t/6300-for-each-ref.sh to handle all `push.default`
strategies. This involves testing `push.default=simple` twice, once
where there is a matching upstream branch and once when there is none.
