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.

We are formalizing a requirement that any remote-tracking branch to be used
as an upstream (i.e. as an argument to --track), _must_ "belong" to a
configured remote by being matched by the "dst" side of a fetch refspec.
This patch encodes the new expected behavior of this test, and marks the
test with "test_expect_failure" in anticipation of a following patch to
introduce the new behavior.

The handing by "git branch --set-upstream-to" against various forms
of errorneous inputs were suboptimal.
* jk/set-upstream-error-cases:
branch: give advice when tracking start-point is missing
branch: mention start_name in set-upstream error messages
branch: improve error message for missing --set-upstream-to ref
branch: factor out "upstream is not a branch" error messages
t3200: test --set-upstream-to with bogus refs

"git branch -m" without any argument noticed an error, but with an
incorrect error message.

These tests pass with the current code, but let's make sure
we don't accidentally break the behavior in the future.
Note that our tests expect failure when we try to set the
upstream to or from a missing branch. Technically we are
just munging config here, so we do not need the refs to
exist. But seeing that they do exist is a good check that
the user has not made a typo.

2. Put the opening quote (') for the test in the same line as

branch_get() can return NULL (so far on detached HEAD only) but some
code paths in builtin/branch.c cannot deal with that and cause
segfaults.
While at there, make sure to bail out when the user gives 2 or more
branches with --set-upstream-to or --unset-upstream, where only the
first branch is processed and the rest silently dropped.

git branch reports the abbreviated hash of the head commit of
a deleted branch to make it easier for a user to undo the

Before a branch is deleted, we check that it points to a valid
commit. With -d we also check that the commit is a merged; this
check is not done with -D.
The reason for that is that commits pointed to by branches should
never go missing; if they do then something broke and it's better
to stop instead of adding to the mess. And a non-merged commit
may contain changes that are worth preserving, so we require the
stronger option -D instead of -d to get rid of them.
If a branch consists of a symref, these concerns don't apply.
Deleting such a branch can't make a commit become unreferenced,
so we don't need to check if it is merged, or even if it is
actually a valid commit. Skip them in that case. This allows
us to delete dangling symref branches.

The existing --set-uptream option can cause confusion, as it uses the
usual branch convention of assuming a starting point of HEAD if none
is specified, causing
git branch --set-upstream origin/master
to create a new local branch 'origin/master' that tracks the current
branch. As --set-upstream already exists, we can't simply change its
behaviour. To work around this, introduce --set-upstream-to which
accepts a compulsory argument indicating what the new upstream branch
should be and one optinal argument indicating which branch to change,
defaulting to HEAD.
The new options allows us to type
git branch --set-upstream-to origin/master
to set the current branch's upstream to be origin's master.

It is very easy to mistype the branch name when editing its description,
e.g.
$ git checkout -b my-topic master
: work work work
: now we are at a good point to switch working something else
$ git checkout master
: ah, let's write it down before we forget what we were doing
$ git branch --edit-description my-tpoic
The command does not notice that branch 'my-tpoic' does not exist. It is
not lost (it becomes description of an unborn my-tpoic branch), but is not
very useful. So detect such a case and error out to reduce the grief
factor from this common mistake.
This incidentally also errors out --edit-description when the HEAD points
at an unborn branch (immediately after "init", or "checkout --orphan"),
because at that point, you do not even have any commit that is part of
your history and there is no point in describing how this particular
branch is different from the branch it forked off of, which is the useful
bit of information the branch description is designed to capture.
We may want to special case the unborn case later, but that is outside the
scope of this patch to prevent more common mistakes before 1.7.9 series
gains too much widespread use.

Overwriting the current branch with a different commit is forbidden, as it
will make the status recorded in the index and the working tree out of
sync with respect to the HEAD. There however is no reason to forbid it if
the current branch is renamed to itself, which admittedly is something
only an insane user would do, but is handy for scripts.

The "git branch" command, while not in listing mode, calls create_branch()
even when the target branch already exists, and it does so even when it is
not interested in updating the value of the branch (i.e. the name of the
commit object that sits at the tip of the existing branch). This happens
when the command is run with "--set-upstream" option.
The earlier safety-measure to prevent "git branch -f $branch $commit" from
updating the currently checked out branch did not take it into account,
and we no longer can update the tracking information of the current branch.
Minimally fix this regression by telling the validation code if it is
called to really update the value of a potentially existing branch, or if
the caller merely is interested in updating auxiliary aspects of a branch.

This patch uses test_path_is_file and test_path_is_missing
instead of "test -f / ! test -f" checks. The former are more
verbose in case of failure and more precise (e.g., is_missing
will check that the entry is actually missing, not just not
a regular file).
As a bonus, this also fixes a few buggy tests that used
"test foo" instead of "test -f foo", and consequently always
reported success.

"git branch -M <foo> <current-branch>" allows updating the current branch
which HEAD points, without the necessary house-keeping that git reset
normally does to make this operation sensible. It also leaves the reflog
in a confusing state (you would be warned when trying to read it).
"git checkout -B <current branch> <foo>" is also partly vulnerable to this
bug; due to inconsistent pre-flight checks it would perform half of its
task and then abort just before rewriting the branch. Again this
manifested itself as the index file getting out-of-sync with HEAD.
"git branch -f" already guarded against this problem, and aborts with
a fatal error.
Update "git branch -M", "git checkout -B" and "git branch -f" to share the
same check before allowing a branch to be created. These prevent you from
updating the current branch.
We considered suggesting the use of "git reset" in the failure message
but concluded that it was not possible to discern what the user was
actually trying to do.

When creating a new branch using the --track option, we must make sure that
we don't try to set an upstream that does not make sense to follow (using
'git pull') or update (using 'git push'). The current code checks against
using HEAD as upstream (since tracking a symref doesn't make sense). However,
tracking a tag doesn't make sense either. Indeed, tracking _any_ ref that is
not a (local or remote) branch doesn't make sense, and should be disallowed.
This patch achieves this by checking that the ref we're trying to --track
resides within refs/heads/* or refs/remotes/*. This new check replaces the
previous check against HEAD.
A couple of testcases are also added, verifying that we cannot create
branches with tags as upstreams.
Finally, some selftests relying on using a non-branch as an upstream have
been reworked or removed:
- t6040: Reverse the meaning of two tests that depend on the ability to
use (lightweight and annotated) tags as upstreams. These two tests were
originally added in commits 1be570f and 57ffc5f, and this patch reverts the
intention of those two commits.
- t7201: Remove part of a test (introduced in 9188ed8) relying on a
non-branch as upstream.

When a branch is marked to merge with another ref (e.g. local 'next' that
merges from and pushes back to origin's 'next', with 'branch.next.merge'
set to 'refs/heads/next'), it makes little sense to base the "branch -d"
safety, whose purpose is not to lose commits that are not merged to other
branches, on the current branch. It is much more sensible to check if it

Many tests depend on that symbolic links work. This introduces a check
that sets the prerequisite tag SYMLINKS if the file system supports
symbolic links. Since so many tests have to check for this prerequisite,
we do the check in test-lib.sh, so that we don't need to repeat the test
in many scripts.
To check for 'ln -s' failures, you can use a FAT partition on Linux:
$ mkdosfs -C git-on-fat 1000000
$ sudo mount -o loop,uid=j6t,gid=users,shortname=winnt git-on-fat /mnt
