The code did not propagate the terminal width to subprocesses via
COLUMNS environment variable, which it now does. This caused
trouble to "git column" helper subprocess when "git tag --column=row"
tried to list the existing tags on a display with non-default width.
* nd/term-columns:
column: fix off-by-one default width
pager: set COLUMNS to term_columns()
By default we want to fill the whole screen if possible, but we do not
want to use up _all_ terminal columns because the last character is
going hit the border, push the cursor over and wrap. Keep it at
default value zero, which will make print_columns() set the width at
term_columns() - 1.
This affects the test in t7004 because effective column width before
was 40 but now 39 so we need to compensate it by one or the output at
39 columns has a different layout.

A signed tag has a detached signature like this:
object ...
[...more header...]
This is the tag body.
-----BEGIN PGP SIGNATURE-----
[opaque gpg data]
-----END PGP SIGNATURE-----
Our parser finds the _first_ line that appears to start a
PGP signature block, meaning we may be confused by a
signature (or a signature-like line) in the actual body.
Let's keep parsing and always find the final block, which
should be the detached signature over all of the preceding
content.

This is the "theoretically more correct" approach of simply
stepping back to the state before plumbing commands started paying
attention to "color.ui" configuration variable.
Let's run with this one.
* jk/ref-filter-colors-fix:
tag: respect color.ui config
Revert "color: check color.ui in git_default_config()"
Revert "t6006: drop "always" color config tests"
Revert "color: make "always" the same as "auto" in config"
Since 11b087adfd (ref-filter: consult want_color() before
emitting colors, 2017-07-13), we expect that setting
"color.ui" to "always" will enable color tag formats even
without a tty. As that commit was built on top of
136c8c8b8f (color: check color.ui in git_default_config(),
2017-07-13) from the same series, we didn't need to touch
tag's config parsing at all.
However, since we reverted 136c8c8b8f, we now need to
explicitly call git_color_default_config() to make this
work.
Let's do so, and also restore the test dropped in 0c88bf5050
(provide --color option for all ref-filter users,
2017-10-03). That commit swapped out our "color.ui=always"
test for "--color" in preparation for "always" going away.
But since it is here to stay, we should test both cases.
Note that for-each-ref also lost its color.ui support as
part of reverting 136c8c8b8f. But as a plumbing command, it
should _not_ respect the color.ui config. Since it also
gained a --color option in 0c88bf5050, that's the correct
way to ask it for color. We'll continue to test that, and
confirm that "color.ui" is not respected.

When ref-filter learned about want_color() in 11b087adfd
(ref-filter: consult want_color() before emitting colors,
2017-07-13), it became useful to be able to turn colors off
and on for specific commands. For git-branch, you can do so
with --color/--no-color.
But for git-for-each-ref and git-tag, the other users of
ref-filter, you have no option except to tweak the
"color.ui" config setting. Let's give both of these commands
the usual color command-line options.
This is a bit more obvious as a method for overriding the
config. And it also prepares us for the behavior of "always"
changing (so that we are still left with a way of forcing
color when our output goes to a non-terminal).

The point of the test-terminal script is to simulate in the
test scripts an environment where output is going to a real
terminal.
But since test-lib.sh also sets TERM=dumb, the simulation
isn't very realistic. The color code will skip auto-coloring
for TERM=dumb, leading to us liberally sprinkling
test_terminal env TERM=vt100 git ...
through the test suite to convince the tests to actually
generate colors. Let's set TERM for programs run under
test_terminal, which is one less thing for test-writers to
remember.
In most cases the callers can be simplified, but note there
is one interesting case in t4202. It uses test_terminal to
check the auto-enabling of --decorate, but the expected
output _doesn't_ contain colors (because TERM=dumb
suppresses them). Using TERM=vt100 is closer to what the
real world looks like; adjust the expected output to match.

When color placeholders like %(color:red) are used in a
ref-filter format, we unconditionally output the colors,
even if the user has asked us for no colors. This usually
isn't a problem when the user is constructing a --format on
the command line, but it means we may do the wrong thing
when the format is fed from a script or alias. For example:
$ git config alias.b 'branch --format=%(color:green)%(refname)'
$ git b --no-color
should probably omit the green color. Likewise, running:
$ git b >branches
should probably also omit the color, just as we would for
all baked-in coloring (and as we recently started to do for
user-specified colors in --pretty formats).
This commit makes both of those cases work by teaching
the ref-filter code to consult want_color() before
outputting any color. The color flag in ref_format defaults
to "-1", which means we'll consult color.ui, which in turn
defaults to the usual isatty() check on stdout. However,
callers like git-branch which support their own color config
(and command-line options) can override that.
The new tests independently cover all three of the callers
of ref-filter (for-each-ref, tag, and branch). Even though
these seem redundant, it confirms that we've correctly
plumbed through all of the necessary config to make colors
work by default.

Change the tag, branch & for-each-ref commands to have a --no-contains
option in addition to their longstanding --contains options.
This allows for finding the last-good rollout tag given a known-bad
<commit>. Given a hypothetically bad commit cf5c7253e0, the git
version to revert to can be found with this hacky two-liner:
(git tag -l 'v[0-9]*'; git tag -l --contains cf5c7253e0 'v[0-9]*') |
sort | uniq -c | grep -E '^ *1 ' | awk '{print $2}' | tail -n 10
With this new --no-contains option the same can be achieved with:
git tag -l --no-contains cf5c7253e0 'v[0-9]*' | sort | tail -n 10
As the filtering machinery is shared between the tag, branch &
for-each-ref commands, implement this for those commands too. A
practical use for this with "branch" is e.g. finding branches which
were branched off between v2.8.0 and v2.10.0:
git branch --contains v2.8.0 --no-contains v2.10.0
The "describe" command also has a --contains option, but its semantics
are unrelated to what tag/branch/for-each-ref use --contains for. A
--no-contains option for "describe" wouldn't make any sense, other
than being exactly equivalent to not supplying --contains at all,
which would be confusing at best.
Add a --without option to "tag" as an alias for --no-contains, for
consistency with --with and --contains. The --with option is
undocumented, and possibly the only user of it is
Junio (<xmqqefy71iej.fsf@gitster.mtv.corp.google.com>). But it's
trivial to support, so let's do that.
The additions to the the test suite are inverse copies of the
corresponding --contains tests. With this change --no-contains for
tag, branch & for-each-ref is just as well tested as the existing
--contains option.
In addition to those tests, add a test for "tag" which asserts that
--no-contains won't find tree/blob tags, which is slightly
unintuitive, but consistent with how --contains works & is documented.

Change the "tag" command to implicitly turn on its --list mode when
provided with a list-like option such as --contains, --points-at etc.
This is for consistency with how "branch" works. When "branch" is
given a list-like option, such as --contains, it implicitly provides
--list. Before this change "tag" would error out on those sorts of
invocations. I.e. while both of these worked for "branch":
git branch --contains v2.8.0 <pattern>
git branch --list --contains v2.8.0 <pattern>
Only the latter form worked for "tag":
git tag --contains v2.8.0 '*rc*'
git tag --list --contains v2.8.0 '*rc*'
Now "tag", like "branch", will implicitly supply --list when a
list-like option is provided, and no other conflicting non-list
options (such as -d) are present on the command-line.
Spelunking through the history via:
git log --reverse -p -G'only allowed with' -- '*builtin*tag*c'
Reveals that there was no good reason for not allowing this in the
first place. The --contains option added in 32c35cfb1e ("git-tag: Add
--contains option", 2009-01-26) made this an error. All the other
subsequent list-like options that were added copied its pattern of
making this usage an error.
The only tests that break as a result of this change are tests that
were explicitly checking that this "branch-like" usage wasn't
permitted. Change those failing tests to check that this invocation
mode is permitted, add extra tests for the list-like options we
weren't testing, and tests to ensure that e.g. we don't toggle the
list mode in the presence of other conflicting non-list options.
With this change errors messages such as "--contains option is only
allowed with -l" don't make sense anymore, since options like
--contain turn on -l. Instead we error out when list-like options such
as --contain are used in conjunction with conflicting options such as
-d or -v.

Change the documentation for --list so that it's described as a
toggle, not as an option that takes a <pattern> as an argument.
Junio initially documented this in b867c7c23a ("git-tag: -l to list
tags (usability).", 2006-02-17), but later Jeff King changed "tag" to
accept multiple patterns in 588d0e834b ("tag: accept multiple patterns
for --list", 2011-06-20).
However, documenting this as "-l <pattern>" was never correct, as
these both worked before Jeff's change:
git tag -l 'v*'
git tag 'v*' -l
One would expect an option that was documented like that to only
accept:
git tag --list
git tag --list 'v*rc*'
And after Jeff's change, one that took multiple patterns:
git tag --list 'v*rc*' --list '*2.8*'
But since it's actually a toggle all of these work as well, and
produce identical output to the last example above:
git tag --list 'v*rc*' '*2.8*'
git tag --list 'v*rc*' '*2.8*' --list --list --list
git tag --list 'v*rc*' '*2.8*' --list -l --list -l --list
Now the documentation is more in tune with how the "branch" command
describes its --list option since commit cddd127b9a ("branch:
introduce --list option", 2011-08-28).

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.

"git tag" did not leave useful message when adding a new entry to
reflog; this was left unnoticed for a long time because refs/tags/*
doesn't keep reflog by default.
* cw/tag-reflog-message:
tag: generate useful reflog message
When tags are created with `--create-reflog` or with the option
`core.logAllRefUpdates` set to 'always', a reflog is created for them.
So far, the description of reflog entries for tags was empty, making the
reflog hard to understand. For example:
6e3a7b3 refs/tags/test@{0}:
Now, a reflog message is generated when creating a tag, following the
pattern "tag: tagging <short-sha1> (<description>)". If
GIT_REFLOG_ACTION is set, the message becomes "$GIT_REFLOG_ACTION
(<description>)" instead. If the tag references a commit object, the
description is set to the subject line of the commit, followed by its
commit date. For example:
6e3a7b3 refs/tags/test@{0}: tag: tagging 6e3a7b3398 (Git 2.12-rc0, 2017-02-03)
If the tag points to a tree/blob/tag objects, the following static
strings are taken as description:
- "tree object"
- "blob object"
- "other tag object"

The "core.logAllRefUpdates" that used to be boolean has been

remote-tracking branches and notes).

ref-filter: add function to print single ref_array_item
gpg-interface, tag: add GPG_VERIFY_OMIT_STATUS flag
When core.logallrefupdates is true, we only create a new reflog for refs
that are under certain well-known hierarchies. The reason is that we
know that some hierarchies (like refs/tags) are not meant to change, and
that unknown hierarchies might not want reflogs at all (e.g., a
hypothetical refs/foo might be meant to change often and drop old
history immediately).
However, sometimes it is useful to override this decision and simply log
for all refs, because the safety and audit trail is more important than
the performance implications of keeping the log around.
This patch introduces a new "always" mode for the core.logallrefupdates
option which will log updates to everything under refs/, regardless
where in the hierarchy it is (we still will not log things like
ORIG_HEAD and FETCH_HEAD, which are known to be transient).

interesting and useful property of version sort:
- The empty string as a configured suffix matches all tagnames,
including tagnames without any suffix, but
- tagnames containing a "real" configured suffix are still ordered
according to that real suffix, because any longer suffix takes
precedence over the empty string.
Exploiting this property we can easily generalize suffix reordering
and specify the order of tags with given suffixes not only before but
even after a main release tag by using the empty suffix to denote the
position of the main release tag, without any algorithm changes:
$ git -c versionsort.prereleaseSuffix=-alpha \
-c versionsort.prereleaseSuffix=-beta \
-c versionsort.prereleaseSuffix="" \
-c versionsort.prereleaseSuffix=-gamma \
-c versionsort.prereleaseSuffix=-delta \
tag -l --sort=version:refname 'v3.0*'
v3.0-alpha1
v3.0-beta1
v3.0
v3.0-gamma1
v3.0-delta1
Since 'versionsort.prereleaseSuffix' is not a fitting name for a
configuration variable to control this more general suffix reordering,
introduce the new variable 'versionsort.suffix'. Still keep the old
configuration variable name as a deprecated alias, though, to avoid
suddenly breaking setups already using it. Ignore the old variable if
both old and new configuration variables are set, but emit a warning
so users will be aware of it and can fix their configuration. Extend
the documentation to describe and add a test to check this more
general behavior.
Note: since the empty suffix matches all tagnames, tagnames with
suffixes not included in the configuration are listed together with
the suffixless main release tag, ordered lexicographically right after
that, i.e. before tags with suffixes listed in the configuration
following the empty suffix.

When comparing tagnames, it is possible that a tagname contains more
than one of the configured prerelease suffixes around the first
different character. After fixing a bug in the previous commit such a
tagname is sorted according to the contained suffix which comes first
in the configuration. This is, however, not quite the right thing to
do in the following corner cases:
1. $ git -c versionsort.suffix=-bar
-c versionsort.suffix=-foo-baz
-c versionsort.suffix=-foo-bar
tag -l --sort=version:refname 'v1*'
v1.0-foo-bar
v1.0-foo-baz
The suffix of the tagname 'v1.0-foo-bar' is clearly '-foo-bar',
so it should be listed last. However, as it also contains '-bar'
around the first different character, it is listed first instead,
because that '-bar' suffix comes first the configuration.
2. One of the configured suffixes starts with the other:
$ git -c versionsort.prereleasesuffix=-pre \
-c versionsort.prereleasesuffix=-prerelease \
tag -l --sort=version:refname 'v2*'
v2.0-prerelease1
v2.0-pre1
v2.0-pre2
Here the tagname 'v2.0-prerelease1' should be the last. When
comparing 'v2.0-pre1' and 'v2.0-prerelease1' the first different
characters are '1' and 'r', respectively. Since this first
different character must be part of the configured suffix, the
'-pre' suffix is not recognized in the first tagname. OTOH, the
'-prerelease' suffix is properly recognized in
'v2.0-prerelease1', thus it is listed first.
Improve version sort in these corner cases, and
- look for a configured prerelease suffix containing the first
different character or ending right before it, so the '-pre'
suffixes are recognized in case (2). This also means that
when comparing tagnames 'v2.0-pre1' and 'v2.0-pre2',
swap_prereleases() would find the '-pre' suffix in both, but then
it will return "undecided" and the caller will do the right thing
by sorting based in '1' and '2'.
- If the tagname contains more than one suffix, then give precedence
to the contained suffix that starts at the earliest offset in the
tagname to address (1).
- If there are more than one suffixes starting at that earliest
position, then give precedence to the longest of those suffixes,
thus ensuring that in (2) the tagname 'v2.0-prerelease1' won't be
sorted based on the '-pre' suffix.
Add tests for these corner cases and adjust the documentation
accordingly.

Version sort with prerelease reordering sometimes puts tagnames in the
wrong order, when the common part of two compared tagnames overlaps
with the leading character(s) of one or more configured prerelease
suffixes. Note the position of "v2.1.0-beta-1":
$ git -c versionsort.prereleaseSuffix=-beta \
tag -l --sort=version:refname v2.1.*
v2.1.0-beta-2
v2.1.0-beta-3
v2.1.0
v2.1.0-RC1
v2.1.0-RC2
v2.1.0-beta-1
v2.1.1
v2.1.2
The reason is that when comparing a pair of tagnames, first
versioncmp() looks for the first different character in a pair of
tagnames, and then the swap_prereleases() helper function looks for a
configured prerelease suffix _starting at_ that character. Thus, when
in the above example the sorting algorithm happens to compare the
tagnames "v2.1.0-beta-1" and "v2.1.0-RC2", swap_prereleases() tries to
match the suffix "-beta" against "beta-1" to no avail, and the two
tagnames erroneously end up being ordered lexicographically.
To fix this issue change swap_prereleases() to look for configured
prerelease suffixes _containing_ the position of that first different
character.
Care must be taken, when a configured suffix is longer than the
tagnames' common part up to the first different character, to avoid
reading memory before the beginning of the tagnames. Add a test that
uses an exceptionally long prerelease suffix to check for this, in the
hope that in case of a regression the illegal memory access causes a
segfault in 'git tag' on one of the commonly used platforms (the test
happens to pass successfully on my Linux system with the safety check
removed), or at least makes valgrind complain.
Under some circumstances it's possible that more than one prerelease
suffixes can be found in the same tagname around that first different
character. With this simple bugfix patch such a tagname is sorted
according to the contained suffix that comes first in the
configuration for now. This is less than ideal in some cases, and the
following patch will take care of those.

The unrelated '--format should list tags as per format given' test
later uses tags matching the same prefix as the version sort tests,
thus was affected by the new tags added for the new tests in this
patch. Change that test to perform its checks on a different set of

The '--force is moot with a non-existing tag name' test creates two
new tags, which are then deleted right after the test is finished,
outside the test_expect_success block, allowing 'git tag -d's output to
pollute the test output.
Use test_when_finished to delete those tags.

This options makes sorting ignore case, which is great when you have
branches named bug-12-do-something, Bug-12-do-some-more and
BUG-12-do-what and want to group them together. Sorting externally may
not be an option because we lose coloring and column layout from
git-branch and git-tag.
The same could be said for filtering, but it's probably less important
because you can always go with the ugly pattern [bB][uU][gG]-* if you're
desperate.
You can't have case-sensitive filtering and case-insensitive sorting (or
the other way around) with this though. For branch and tag, that should
be no problem. for-each-ref, as a plumbing, might want finer control.
But we can always add --{filter,sort}-ignore-case when there is a need
for it.

When we create a signature, it may happen that gpg returns with

Check for the correct signature creation status to catch these cases
better. Really, --status-fd parsing is the only way to check gpg status
reliably. We do the same for verify already.

The `tag.forcesignannotated` configuration variable makes "git tag"
that would implicitly create an annotated tag to instead create a
signed tag. For example
$ git tag -m "This is a message" tag-with-message
$ git tag -F message-file tag-with-message
would create a signed tag if the configuration variable is in
effect. To override this from the command line, the user can
explicitly ask for an annotated tag, like so:
$ git tag -a -m "This is a message" tag-with-message
$ git tag -a -F message-file tag-with-message
Creation of a light-weight tag, i.e.
$ git tag lightweight
is not affected.

"git tag" started listing a tag "foo" as "tags/foo" when a branch
named "foo" exists in the same repository; remove this unnecessary
disambiguation, which is a regression introduced in v2.7.0.
* jk/list-tag-2.7-regression:
tag: do not show ambiguous tag names as "tags/foo"
t6300: use test_atom for some un-modern tests
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.

The Git CodingGuidelines prefer the $(...) construct for command
substitution instead of using the backquotes `...`.
The backquoted form is the traditional method for command
substitution, and is supported by POSIX. However, all but the
simplest uses become complicated quickly. In particular, embedded
command substitutions and/or the use of double quotes require
careful escaping with the backslash character.
The patch was generated by:
for _f in $(find . -name "*.sh")
do
perl -i -pe 'BEGIN{undef $/;} s/`(.+?)`/\$(\1)/smg' "${_f}"
done
and then carefully proof-read.
