"git name-rev" assigned a phony "far in the future" date to tips of
refs that are not pointing at tag objects, and favored names based
on a ref with the oldest date. This made it almost impossible for
an unannotated tags and branches to be counted as a viable base,
which was especially problematic when the command is run with the
"--tags" option. If an unannotated tag that points at an ancient
commit and an annotated tag that points at a much newer commit
reaches the commit that is being named, the old unannotated tag was
ignored.
Update the "taggerdate" field of the rev-name structure, which is
initialized from the tip of ref, to have the committer date if the
object at the tip of ref is a commit, not a tag, so that we can
optionally take it into account when doing "is this name better?"
comparison logic.
When "name-rev" is run without the "--tags" option, the general
expectation is still to name the commit based on a tag if possible,
but use non-tag refs as fallback, and tiebreak among these non-tag
refs by favoring names with shorter hops from the tip. The use of a
phony "far in the future" date in the original code was an effective
way to ensure this expectation is held: a non-tag tip gets the same
"far in the future" timestamp, giving precedence to tags, and among
non-tag tips, names with shorter hops are preferred over longer
hops, without taking the "taggerdate" into account. As we are
taking over the "taggerdate" field to store the committer date for
tips with commits:
(1) keep the original logic when comparing names based on two refs
both of which are from refs/tags/;
(2) favoring a name based on a ref in refs/tags/ hierarchy over
a ref outside the hierarchy;
(3) between two names based on a ref both outside refs/tags/, give
precedence to a name with shorter hops and use "taggerdate"
only to tie-break.
A change to t4202 is a natural consequence. The test creates a
commit on a branch "side" and points at it with an unannotated tag
"refs/tags/side-2". The original code couldn't decide which one to
favor at all, and gave a name based on a branch (simply because
refs/heads/side sorts earlier than refs/tags/side-2). Because the
updated logic is taught to favor refs in refs/tags/ hierarchy, the
the test is updated to expect to see tags/side-2 instead.
[mjg: open-coded the comparisons in is_better_name(), dropping a
helper macro used in the original]

When we encounter a new ref that could describe the commit we are
looking at, we compare the name that is formed using that ref and
the name we found so far and pick a better one.
Factor the comparison logic out to a separate helper function, while
keeping the current logic the same (i.e. a name that is based on an
older tag is better, and if two tags of the same age can reach the
commit, the one with fewer number of hops to reach the commit is
better).

Jan Palus noticed that some here-doc are spelled incorrectly,
resulting the entire remainder of the test snippet being slurped
into the "expect" file as if it were data, e.g. in this sequence
cat >expect <<EOF &&
... expectation ...
EOF
git $cmd_being_tested >actual &&
test_cmp expect actual
the last command of the test is "cat" that sends everything to
'expect' and succeeds.
Fixing these issues in t7004 and t7030 reveals that "git tag -v"
and "git verify-tag" with their --format option do not work as the
test was expecting originally. Instead of showing both valid tags
and tags with incorrect signatures on their output, tags that do not
pass verification are omitted from the output. Another breakage that
is uncovered is that these tests must be restricted to environment
where gpg is available.
Arguably, that is a safer behaviour, and because the format
specifiers like %(tag) do not have a way to show if the signature
verifies correctly, the command with the --format option cannot be
used to get a list of tags annotated with their signature validity
anyway.
For now, let's fix the here-doc syntax, update the expectation to
match the reality, and update the test prerequisite.
Maybe later when we extend the --format language available to "git
tag -v" and "git verify-tag" to include things like "%(gpg:status)",
we may want to change the behaviour so that piping a list of tag
names into
xargs git verify-tag --format='%(gpg:status) %(tag)'
becomes a good way to produce such a list, but that is a separate
topic.

We found a few run-away here documents that are started with an
end-of-here-doc marker that is incorrectly spelled, e.g.
git some command >actual &&
cat <<EOF >expect
...
EOF &&
test_cmp expect actual
which ends up slurping the entire remainder of the script as if it
were the data. Often the command that gets misused like this exits
without failure (e.g. "cat" in the above example), which makes the
command appear to work, without ever executing the remainder of the
test.
Piggy-back on the test that catches &&-chain breakage to detect this
case as well.

|

When using rebase --interactive where one of the lines is marked as
'edit' this is the resulting output:
Stopped at ec3b9c4... stuffYou can amend the commit now, with
git commit --amend
Once you are satisfied with your changes, run
git rebase --continue
A newline character is missing at the end of the "Stopped at ..." line and
before the "You can amend ..." line. This patch fixes the malformed output by
adding the missing newline character to the end of the "Stopped at ..." line.

"git send-pack --stateless-rpc" puts each request in a sequence of pkt-lines
followed by a flush-pkt. The push option code forgot about this and sends push
options and their terminating delimiter as ordinary pkt-lines that get their
length header stripped off by remote-curl before being sent to the server.
The result is multiple malformed requests, which the server rejects.
Fortunately send-pack --stateless-rpc already is aware of this "pkt-line within
pkt-line" framing for the update commands that precede push options. Handle
push options the same way.

There are three issues with the test:
* The syntax of the here-doc was wrong, such that the entire test was
sucked into the here-doc, which is why the test succeeded.
* The variable $submodulesha1 was not expanded as it was inside a quoted
here text. We do not want to quote EOF marker for this.
* The redirection from the git command to the output file for comparison
was wrong as the -C operator from git doesn't apply to the redirect path.
Also we're interested in stderr of that command.

git-describe tells you the version number you're at, or errors out, e.g.
when you run it outside of a repository, which may happen when downloading
a tar ball instead of using git to obtain the source code.
To keep this property of only erroring out, when not in a repository,
severe (submodule) errors must be downgraded to reporting them gently
instead of having git-describe error out completely.
To achieve that a flag '--broken' is introduced, which is in the same
vein as '--dirty' but uses an actual child process to check for dirtiness.
When that child dies unexpectedly, we'll append '-broken' instead of
'-dirty'.
