bb8efa1772 t3200: add test for single parameter passed to -m option
Add a test for the case when only one parameter is passed to '-m'
(move/rename) option.

For example - if 'git branch -m bbb' is run while checked out on aaa
branch, it should rename the currently checked out branch to bbb.
There was no test for this particular case with only one parameter
for -m option. However, there's one similar test case for -M option.

Add test for making sure HEAD points to the bbb (new branch name). Also
add a test for making sure the reflog that is moved to 'bbb' retains
entries created for the currently checked out branch. Note that since
the topmost entry on reflog for bbb will be about branch creation, we
compare bbb@{1} (instead of bbb@{0}) with aaa@{0} to make sure the
reflog for bbb retains entries from aaa.

b8f354f294 branch test: fix invalid config key access
Fixes the test by changing "branch.s/s/dummy" to "branch.s/s.dummy" which is
the right way of accessing config key "branch.s/s.dummy". Purpose of
this test is to confirm that this key doesn't exist after the branch
"s/s" has been renamed to "s".

Earlier it was trying to access invalid config key and hence was getting
an error. However, this wasn't caught because we were expecting the
command to fail for other reason as mentioned above.

17d6c744dc ref-filter: make combining --merged & --no-merged an error
Change the behavior of specifying --merged & --no-merged to be an
error, instead of silently picking the option that was provided last.

Subsequent changes of mine add a --no-contains option in addition to
the existing --contains. Providing both of those isn't an error, and
has actual meaning.

Making its cousins have different behavior in this regard would be
confusing to the user, especially since we'd be silently disregarding
some of their command-line input.

39ee4c6c2f branch: record creation of renamed branch in HEAD's log
Renaming the current branch adds an event to the current branch's log
and to HEAD's log.  However, the logged entries differ.  The entry in
the branch's log represents the entire renaming operation (the old and
new hash are identical), whereas the entry in HEAD's log represents
the deletion only (the new sha1 is null).

Extend replace_each_worktree_head_symref(), whose only caller is
branch_rename(), to take a reflog message argument.  This allows the
creation of the new ref to be recorded in HEAD's log.  As a result,
the renaming event is represented by two entries (a deletion and a
creation entry) in HEAD's log.

It's a bit unfortunate that the branch's log and HEAD's log now
represent the renaming event in different ways.  Given that the
renaming operation is not atomic, the two-entry form is a more
accurate representation of the operation and is more useful for
debugging purposes if a failure occurs between the deletion and
creation events.  It would make sense to move the branch's log to the
two-entry form, but this would involve changes to how the rename is
carried out and to how the update flags and reflogs are processed for
deletions, so it may not be worth the effort.

893dbf5ba1 rename_ref: replace empty message in HEAD's log
When the current branch is renamed, the deletion of the old ref is
recorded in HEAD's log with an empty message.  Now that delete_ref()
accepts a reflog message, provide a more descriptive message by
passing along the log message that is given to rename_ref().

The next step will be to extend HEAD's log to also include the second
part of the rename, the creation of the new branch.

1edbaac3bb tests: use test_i18n* functions to suppress false positives
The test functions test_i18ncmp and test_i18ngrep pretend success if run
under GETTEXT_POISON. By using those functions to test output which is
correctly marked as translatable, enables one to detect if the strings
newly marked for translation are from plumbing output. If they are
indeed from plumbing, the test would fail, and the string should be
unmarked, since it is not seen by users.

Thus, it is productive to not have false positives when running the test
under GETTEXT_POISON. This commit replaces normal test functions by
their i18n aware variants in use-cases know to be correctly marked for
translation, suppressing false positives.

12fd3496d1 refs: don't dereference on rename
When renaming refs, don't dereference either the origin or the destination
before renaming.

The origin does not need to be dereferenced because it is presently
forbidden to rename symbolic refs.

Not dereferencing the destination fixes a bug where renaming on top of
a broken symref would use the pointed-to ref name for the moved
reflog.

Add a test for the reflog bug.

b81842cbbb branch: die on config error when unsetting upstream
When we try to unset upstream configurations we do not check
return codes for the `git_config_set` functions. As those may
indicate that we were unable to unset the respective
configuration we may exit successfully without any error message
while in fact the upstream configuration was not unset.

Fix this by dying with an error message when we cannot unset the

27852b2c53 branch: report errors in tracking branch setup
When setting up a new tracking branch fails due to issues with
the configuration file we do not report any errors to the user
and pretend setting the tracking branch succeeded.

Setting up the tracking branch is handled by the
`install_branch_config` function. We do not want to simply die
there as the function is not only invoked when explicitly setting
upstream information with `git branch --set-upstream-to=`, but
also by `git push --set-upstream` and `git clone`. While it is
reasonable to die in the explict first case, we would lose
information in the latter two cases, so we only print the error
message but continue the program as usual.

There are still a few tests which need direct access to reflogs: to

save/restore reflogs, to check the format of raw reflog data, and to
remove not just reflog contents, but the reflogs themselves. All cases

62a2d52514 branch -d: avoid repeated symref resolution
If a repository gets in a broken state with too much symref nesting,
it cannot be repaired with "git branch -d":

 $ git symbolic-ref refs/heads/nonsense refs/heads/nonsense
 $ git branch -d nonsense
 error: branch 'nonsense' not found.

Worse, "git update-ref --no-deref -d" doesn't work for such repairs
either:

 $ git update-ref -d refs/heads/nonsense
 error: unable to resolve reference refs/heads/nonsense: Too many levels of symbolic links

Fix both by teaching resolve_ref_unsafe a new RESOLVE_REF_NO_RECURSE
flag and passing it when appropriate.

Callers can still read the value of a symref (for example to print a
message about it) with that flag set --- resolve_ref_unsafe will
resolve one level of symrefs and stop there.

512477b175 tests: use "env" to run commands with temporary env-var settings
Ordinarily, we would say "VAR=VAL command" to execute a tested

This however does not work if 'command' is a shell function (most
notably 'test_must_fail'); the result of the assignment is retained
and affects later commands.

To avoid this, we used to assign and export environment variables
and run such a test in a subshell, like so:

        (
                VAR=VAL && export VAR &&
                test_must_fail git command to be tested
        )

But with "env" utility, we should be able to say:

which is much shorter and easier to read.

There is one test in t3200-branch.sh that invokes a help page. The
intent of the redirections applied to the command invocation is to avoid
that the man page viewer interferes with the automated test. But when
the default format is not "man", this does not have the intended effect,
and the HTML manual page is opened during the test run. Request "man"

1d7358c524 branch.c: Relax unnecessary requirement on upstream's remote ref name
When creating an upstream relationship, we use the configured remotes and
their refspecs to determine the upstream configuration settings
branch.<name>.remote and branch.<name>.merge. However, if the matching
refspec does not have refs/heads/<something> on the remote side, we end
up rejecting the match, and failing the upstream configuration.

It could be argued that when we set up an branch's upstream, we want that
upstream to also be a proper branch in the remote repo. Although this is
typically the common case, there are cases (as demonstrated by the previous
patch in this series) where this requirement prevents a useful upstream
relationship from being formed. Furthermore:

 - We have fundamentally no say in how the remote repo have organized its
   branches. The remote repo may put branches (or branch-like constructs
   that are insteresting for downstreams to track) outside refs/heads/*.

 - The user may intentionally want to track a non-branch from a remote
   repo, by using a branch and configured upstream in the local repo.

Relaxing the checking to only require a matching remote/refspec allows the
testcase introduced in the previous patch to succeed, and has no negative
effect on the rest of the test suite.

This patch fixes a behavior (arguably a regression) first introduced in
41c21f2 (branch.c: Validate tracking branches with refspecs instead of
refs/remotes/*) on 2013-04-21 (released in >= v1.8.3.2).

62d94a3aa6 t3200: Add test demonstrating minor regression in 41c21f2
In 41c21f2 (branch.c: Validate tracking branches with refspecs instead of
refs/remotes/*), we changed the rules for what is considered a valid tracking
branch (a.k.a. upstream branch). We now use the configured remotes and their
refspecs to determine whether a proposed tracking branch is in fact within
the domain of a remote, and we then use that information to deduce the
upstream configuration (branch.<name>.remote and branch.<name>.merge).

However, with that change, we also check that - in addition to a matching
refspec - the result of mapping the tracking branch through that refspec
(i.e. the corresponding ref name in the remote repo) happens to start with
"refs/heads/". In other words, we require that a tracking branch refers to
a _branch_ in the remote repo.

Now, consider that you are e.g. setting up an automated building/testing
infrastructure for a group of similar "source" repositories. The build/test
infrastructure consists of a central scheduler, and a number of build/test
"slave" machines that perform the actual build/test work. The scheduler
monitors the group of similar repos for changes (e.g. with a periodic
"git fetch"), and triggers builds/tests to be run on one or more slaves.
Graphically the changes flow between the repos like this:

  Source #1 -------v          ----> Slave #1
                             /
  Source #2 -----> Scheduler -----> Slave #2
                             \
  Source #3 -------^          ----> Slave #3

        ...                           ...

The scheduler maintains a single Git repo with each of the source repos set
up as distinct remotes. The slaves also need access to all the changes from
all of the source repos, so they pull from the scheduler repo, but using the
following custom refspec:

  remote.origin.fetch = "+refs/remotes/*:refs/remotes/*"

This makes all of the scheduler's remote-tracking branches automatically
available as identical remote-tracking branches in each of the slaves.

Now, consider what happens if a slave tries to create a local branch with
one of the remote-tracking branches as upstream:

  git branch local_branch --track refs/remotes/source-1/some_branch

Git now looks at the configured remotes (in this case there is only "origin",
pointing to the scheduler's repo) and sees refs/remotes/source-1/some_branch
matching origin's refspec. Mapping through that refspec we find that the
corresponding remote ref name is "refs/remotes/source-1/some_branch".
However, since this remote ref name does not start with "refs/heads/", we
discard it as a suitable upstream, and the whole command fails.

This patch adds a testcase demonstrating this failure by creating two
source repos ("a" and "b") that are forwarded through a scheduler ("c")
to a slave repo ("d"), that then tries create a local branch with an
upstream. See the next patch in this series for the exciting conclusion
to this story...

81f339dc3d t3200: Minor fix when preparing for tracking failure
We're testing that trying to --track a ref that is not covered by any remote
refspec should fail. For that, we want to have refs/remotes/local/master
present, but we also want the remote.local.fetch refspec to NOT match
refs/remotes/local/master (so that the tracking setup will fail, as intended).
However, when doing "git fetch local" to ensure the existence of
refs/remotes/local/master, we must not already have changed remote.local.fetch
so as to cause refs/remotes/local/master not to be fetched. Therefore, set
remote.local.fetch to refs/heads/*:refs/remotes/local/* BEFORE we fetch, and
then reset it to refs/heads/s:refs/remotes/local/s AFTER we have fetched
(but before we test --track).

41c21f22d0 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.

9c9cd39a0c t3200.39: tracking setup should fail if there is no matching refspec.
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.

8a3e5ecdaa t3200: test --set-upstream-to with bogus refs
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.

8efb8899cf branch: segfault fixes and validation
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.

0fe700e311 branch: skip commit checks when deleting symref branches
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.

This interface is error prone, and a better one (--set-upstream-to)
exists. Add a message listing the alternatives and suggest how to fix
a --set-upstream invocation in case the user only gives one argument
which causes a local branch with the same name as a remote-tracking
one to be created. The typical case is

    git branch --set-upstream origin/master

when the user meant

    git branch --set-upstream master origin/master

assuming that the current branch is master. Show a message telling the
user how to undo their action and get what they wanted. For the
command above, the message would be

The --set-upstream flag is deprecated and will be removed. Consider using --track or --set-upstream-to
Branch origin/master set up to track local branch master.

If you wanted to make 'master' track 'origin/master', do this:

    git branch -d origin/master
    git branch --set-upstream-to origin/master
