Since b7cc53e9 (tag.c: use 'ref-filter' APIs, 2015-07-11),
git-tag has started showing tags with ambiguous names (i.e.,
when both "heads/foo" and "tags/foo" exists) as "tags/foo"
instead of just "foo". This is both:
- pointless; the output of "git tag" includes only
refs/tags, so we know that "foo" means the one in
"refs/tags".
and
- ambiguous; in the original output, we know that the line
"foo" means that "refs/tags/foo" exists. In the new
output, it is unclear whether we mean "refs/tags/foo" or
"refs/tags/tags/foo".
The reason this happens is that commit b7cc53e9 switched
git-tag to use ref-filter's "%(refname:short)" output
formatting, which was adapted from for-each-ref. This more
general code does not know that we care only about tags, and
uses shorten_unambiguous_ref to get the short-name. We need
to tell it that we care only about "refs/tags/", and it
should shorten with respect to that value.
In theory, the ref-filter code could figure this out by us
passing FILTER_REFS_TAGS. But there are two complications
there:
1. The handling of refname:short is deep in formatting
code that does not even have our ref_filter struct, let
alone the arguments to the filter_ref struct.
2. In git v2.7.0, we expose the formatting language to the
user. If we follow this path, it will mean that
"%(refname:short)" behaves differently for "tag" versus
"for-each-ref" (including "for-each-ref refs/tags/"),
which can lead to confusion.
Instead, let's add a new modifier to the formatting
language, "strip", to remove a specific set of prefix
components. This fixes "git tag", and lets users invoke the
same behavior from their own custom formats (for "tag" or
"for-each-ref") while leaving ":short" with its same
consistent meaning in all places.
We introduce a test in t7004 for "git tag", which fails
without this patch. We also add a similar test in t3203 for
"git branch", which does not actually fail. But since it is
likely that "branch" will eventually use the same formatting
code, the test helps defend against future regressions.

Because this script has to test so many formatters, we have
the nice "test_atom" helper, but we don't use it
consistently. Let's do so. This is shorter, gets rid of some
tests that have their "expected" setup outside of a
test_expect_success block, and lets us organize the changes
better (e.g., putting "refname:short" near "refname").
We also expand the "%(push)" tests a little to match the
"%(upstream)" ones.

The return value of strftime is poorly designed; when it
returns 0, the caller cannot tell if the buffer was not
large enough, or if the output was actually 0 bytes. In the
original implementation of strbuf_addftime, we simply punted
and guessed that our 128-byte hint would be large enough.
We can do better, though, if we're willing to treat strftime
like less of a black box. We can munge the incoming format
to make sure that it never produces 0-length output, and
then "fix" the resulting output. That lets us reliably grow
the buffer based on strftime's return value.

This feeds the format directly to strftime. Besides being a
little more flexible, the main advantage is that your system
strftime may know more about your locale's preferred format
(e.g., how to spell the days of the week).

Just as we have "%(upstream)" to report the "@{upstream}"

The code handling %(upstream:track) and %(upstream:trackshort)
assumed that it always had a valid branch that had been sanitized
earlier in populate_value(), and thus did not check the return value
of the call to stat_tracking_info().
While there is indeed some sanitization code that basically
corresponds to stat_tracking_info() returning 0 (no base branch
set), the function can also return -1 when the base branch did exist
but has since then been deleted.
In this case, num_ours and num_theirs had undefined values and a
call to `git for-each-ref --format="%(upstream:track)"` could print
spurious values such as
[behind -111794512]
[ahead 38881640, behind 5103867]
even for repositories with one single commit.
Verify stat_tracking_info()'s return value and do not print anything
if it returns -1. This behavior also matches the documentation ("has
no effect if the ref does not have tracking information associated
with it").

If you ask for-each-ref to print each ref and its object,
like:
git for-each-ref --format='%(objectname) %(refname)'
this should involve little more work than looking at the ref
files (and packed-refs) themselves. However, for-each-ref
will actually load each object from disk just to print its
sha1. For most repositories, this isn't a big deal, but it
can be noticeable if you have a large number of refs to
print. Here are best-of-five timings for the command above
on a repo with ~10K refs:
[before]
real 0m0.112s
user 0m0.092s
sys 0m0.016s
[after]
real 0m0.014s
user 0m0.012s
sys 0m0.000s
This patch checks for %(objectname) and %(objectname:short)
before we actually parse the object (and the rest of the
code is smart enough to avoid parsing if we have filled all
of our placeholders).
Note that we can't simply move the objectname parsing code
into the early loop. If the "deref" form %(*objectname) is
used, then we do need to parse the object in order to peel
the tag. So instead of moving the code, we factor it out
into a separate function that can be called for both cases.
While we're at it, we add some basic tests for the
dereferenced placeholders, which were not tested at all
before. This helps ensure we didn't regress that case.

Generally the format of a git tag or commit message is:
subject
body body body
body body body
However, we occasionally see multiline subjects like:
subject
with multiple
lines
body body body
body body body
The rest of git treats these multiline subjects as something
to be concatenated and shown as a single line (e.g., "git
log --pretty=format:%s" will do so since f53bd74). For
consistency, for-each-ref should do the same with its
"%(subject)".

Tries to shorten the refname to a non-ambiguous name.
Szeder Gábor noticed that the git bash completion takes a
tremendous amount of time to strip leading components from
heads and tags refs (i.e. refs/heads, refs/tags, ...). He
proposed a new atom called 'refbasename' which removes at
most two leading components from the ref name.
I myself, proposed a more dynamic solution, which strips off
common leading components with the matched pattern.
But the current bash solution and both proposals suffer from
one mayor problem: ambiguous refs.
A ref is ambiguous, if it resolves to more than one full refs.
I.e. given the refs refs/heads/xyzzy and refs/tags/xyzzy. The
(short) ref xyzzy can point to both refs.
( Note: Its irrelevant whether the referenced objects are the
same or not. )
This proposal solves this by checking for ambiguity of the
shorten ref name.
The shortening is done with the same rules for resolving refs
but in the reverse order. The short name is checked if it
resolves to a different ref.
To continue the above example, the output would be like this:
heads/xyzzy
xyzzy
So, if you want just tags, xyzzy is not ambiguous, because it
will resolve to a tag. If you need the heads you get a also
a non-ambiguous short form of the ref.
To integrate this new format into the bash completion to get
only non-ambiguous refs is beyond the scope of this patch.

As a general principle, we should not use "git diff" to validate the
results of what git command that is being tested has done. We would not

Originally, test_expect_failure was designed to be the opposite
of test_expect_success, but this was a bad decision. Most tests
run a series of commands that leads to the single command that
needs to be tested, like this:
test_expect_{success,failure} 'test title' '
setup1 &&
setup2 &&
setup3 &&
what is to be tested
'
And expecting a failure exit from the whole sequence misses the
point of writing tests. Your setup$N that are supposed to
succeed may have failed without even reaching what you are
trying to test. The only valid use of test_expect_failure is to
check a trivial single command that is expected to fail, which
is a minority in tests of Porcelain-ish commands.
This large-ish patch rewrites all uses of test_expect_failure to
use test_expect_success and rewrites the condition of what is
tested, like this:
test_expect_success 'test title' '
setup1 &&
setup2 &&
setup3 &&
! this command should fail
'
test_expect_failure is redefined to serve as a reminder that
that test *should* succeed but due to a known breakage in git it
currently does not pass. So if git-foo command should create a
file 'bar' but you discovered a bug that it doesn't, you can
write a test like this:
test_expect_failure 'git-foo should create bar' '
rm -f bar &&
git foo &&
test -f bar
'
This construct acts similar to test_expect_success, but instead
of reporting "ok/FAIL" like test_expect_success does, the
outcome is reported as "FIXED/still broken".

for-each-ref can accept only one quoting style. For this reason it uses
OPT_BIT for the quoting style switches so that it is easy to check for
more than one bit being set. However, not all symbolic constants were
