branch.c: Validate tracking branches with refspecs instead of refs/remotes/*
The current code for validating tracking branches (e.g. the argument to
the -t/--track option) hardcodes refs/heads/* and refs/remotes/* as the
potential locations for tracking branches. This works with the refspecs
created by "git clone" or "git remote add", but is suboptimal in other
cases:
- If "refs/remotes/foo/bar" exists without any association to a remote
(i.e. there is no remote named "foo", or no remote with a refspec
that matches "refs/remotes/foo/bar"), then it is impossible to set up
a valid upstream config that tracks it. Currently, the code defaults
to using "refs/remotes/foo/bar" from repo "." as the upstream, which
works, but is probably not what the user had in mind when running
"git branch baz --track foo/bar".
- If the user has tweaked the fetch refspec for a remote to put its
remote-tracking branches outside of refs/remotes/*, e.g. by running
git config remote.foo.fetch "+refs/heads/*:refs/foo_stuff/*"
then the current code will refuse to use its remote-tracking branches
as --track arguments, since they do not match refs/remotes/*.
This patch removes the "refs/remotes/*" requirement for upstream branches,
and replaces it with explicit checking of the refspecs for each remote to
determine whether a given --track argument is a valid remote-tracking
branch. This solves both of the above problems, since the matching refspec
guarantees that there is a both a remote name and a remote branch name
that can be used for the upstream config.
However, this means that refs located within refs/remotes/* without a
corresponding remote/refspec will no longer be usable as upstreams.
The few existing tests which depended on this behavioral quirk has
already been fixed in the preceding patches.
This patch fixes the last remaining test failure in t2024-checkout-dwim.
