Junio C Hamano 1c0b983a77 Merge branch 'jk/ref-filter-colors-fix'
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.

  tag: respect color.ui config

  Revert "t6006: drop "always" color config tests"

Jeff King b521fd1228 tag: respect color.ui 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.

Jeff King 0c88bf5050 provide --color option for all ref-filter users
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 "tag.pager" configuration variable was useless for those who

pager depending on what operation is being carried out to fix this,
and then "git tag -l" is made to run pager by default.

Martin Ågren ff1e72483f tag: change default of pager.tag to "on"
The previous patch taught `git tag` to only respect `pager.tag` in
list-mode. That patch left the default value of `pager.tag` at "off".

After that patch, it makes sense to let the default value be "on"
instead, since it will help with listing many tags, but will not hurt
users of `git tag -a` as it would have before. Make that change. Update
documentation and tests.

Martin Ågren de121ffe57 tag: respect pager.tag in list-mode only
Using, e.g., `git -c pager.tag tag -a new-tag` results in errors such as
"Vim: Warning: Output is not to a terminal" and a garbled terminal.
Someone who makes use of both `git tag -a` and `git tag -l` will
probably not set `pager.tag`, so that `git tag -a` will actually work,
at the cost of not paging output of `git tag -l`.

Use the mechanisms introduced in two earlier patches to ignore
`pager.tag` in git.c and let the `git tag` builtin handle it on its own.
Only respect `pager.tag` when running in list-mode.

There is a window between where the pager is started before and after
this patch. This means that early errors can behave slightly different
before and after this patch. Since operation-parsing has to happen
inside this window, this can be seen with `git -c pager.tag="echo pager
is used" tag -l --unknown-option`. This change in paging-behavior should
be acceptable since it only affects erroneous usages.

Update the documentation and update tests.

If an alias is used to run `git tag -a`, then `pager.tag` will still be
respected. Document this known breakage. It will be fixed in a later
commit. Add a similar test for `-l`, which works.

Jeff King 18a2565016 ref-filter: provide a function for parsing sort options
The ref-filter module currently provides a callback suitable
for parsing command-line --sort options. But since git-tag
also supports the tag.sort config option, it needs a
function whose implementation is quite similar, but with a
slightly different interface. The end result is that
builtin/tag.c has a copy-paste of parse_opt_ref_sorting().

Instead, let's provide a function to parse an arbitrary
sort string, which we can then trivially wrap to make the
parse_opt variant.

Jeff King 4a68e36d7d ref-filter: abstract ref format into its own struct
The ref-filter module provides routines for formatting a ref
for output. The fundamental interface for the format is a
"const char *" containing the format, and any additional
options need to be passed to each invocation of
show_ref_array_item.

Instead, let's make a ref_format struct that holds the
format, along with any associated format options. That will
make some enhancements easier in the future:

  1. new formatting options can be added without disrupting
     existing callers

  2. some state can be carried in the struct rather than as
     global variables

For now this just has the text format itself along with the
quote_style option, but we'll add more fields in future patches.

Jeff King 2eda0102be check return value of verify_ref_format()
Users of the ref-filter code must call verify_ref_format()
before formatting any refs, but most ignore its return
value. This means we may print an error on a syntactically
bogus pattern, but keep going anyway.

In most cases this results in a fatal error when we actually
try to format a ref. But if you have no refs to show at all,
then the behavior is confusing: git prints the error from
verify_ref_format(), then exits with code 0 without showing
any output.  Let's instead abort immediately if we know we
have a bogus format.

We'll output the usage information if we have it handy (just
like the existing call in cmd_for_each_ref() does), and
otherwise just die().

brian m. carlson bc83266abe Convert lookup_commit* to struct object_id
Convert lookup_commit, lookup_commit_or_die,
lookup_commit_reference, and lookup_commit_reference_gently to take
struct object_id arguments.

Introduce a temporary in parse_object buffer in order to convert this
function.  This is required since in order to convert parse_object and
parse_object_buffer, lookup_commit_reference_gently and
lookup_commit_or_die would need to be converted.  Not introducing a
temporary would therefore require that lookup_commit_or_die take a
struct object_id *, but lookup_commit would take unsigned char *,
leaving a confusing and hard-to-use interface.

parse_object_buffer will lose this temporary in a later patch.

Jean-Noel Avila c3027be9d1 i18n: remove i18n from tag reflog message
The building of the reflog message is using strbuf, which is not
friendly with internationalization frameworks. No other reflog
messages are translated right now and switching all the messages to
i18n would require a major rework of the way the messages are built.

Jeff King 7f897b6f17 avoid using fixed PATH_MAX buffers for refs
Many functions which handle refs use a PATH_MAX-sized buffer
to do so. This is mostly reasonable as we have to write
loose refs into the filesystem, and at least on Linux the 4K
PATH_MAX is big enough that nobody would care. But:

  1. The static PATH_MAX is not always the filesystem limit.

  2. On other platforms, PATH_MAX may be much smaller.

  3. As we move to alternate ref storage, we won't be bound
     by filesystem limits.

Let's convert these to heap buffers so we don't have to
worry about truncation or size limits.

We may want to eventually constrain ref lengths for sanity
and to prevent malicious names, but we should do so
consistently across all platforms, and in a central place
(like the ref code).

Jeff King b0ceab98d7 tag: use strbuf to format tag header
We format the tag header into a fixed 1024-byte buffer. But
since the tag-name and tagger ident can be arbitrarily
large, we may unceremoniously die with "tag header too big".
Let's just use a strbuf instead.

Note that it looks at first glance like we can just format
this directly into the "buf" strbuf where it will ultimately
go. But that buffer may already contain the tag message, and
we have no easy way to prepend formatted data to a strbuf
(we can only splice in an already-generated buffer). This
isn't a performance-critical path, so going through an extra
buffer isn't a big deal.

Ævar Arnfjörð Bjarmason ac3f5a3468 ref-filter: add --no-contains option to tag/branch/for-each-ref
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.

Ævar Arnfjörð Bjarmason 6a338149f6 tag: implicitly supply --list given another list-like option
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.

Kyle Meyer 755b49ae96 delete_ref: accept a reflog message argument
When the current branch is renamed with 'git branch -m/-M' or deleted
with 'git update-ref -m<msg> -d', the event is recorded in HEAD's log
with an empty message.  In preparation for adding a more meaningful
message to HEAD's log in these cases, update delete_ref() to take a
message argument and pass it along to ref_transaction_delete().
Modify all callers to pass NULL for the new message argument; no
change in behavior is intended.

Note that this is relevant for HEAD's log but not for the deleted
ref's log, which is currently deleted along with the ref.  Even if it
were not, an entry for the deletion wouldn't be present in the deleted
ref's log.  files_transaction_commit() writes to the log if
REF_NEEDS_COMMIT or REF_LOG_ONLY are set, but lock_ref_for_update()
doesn't set REF_NEEDS_COMMIT for the deleted ref because REF_DELETING
is set.  In contrast, the update for HEAD has REF_LOG_ONLY set by
split_head_update(), resulting in the deletion being logged.

Cornelius Weig df8512ede8 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"

Adding --format to git tag -v mutes the default output of the GPG
verification and instead prints the formatted tag object.
This allows callers to cross-check the tagname from refs/tags with
the tagname from the tag object header upon GPG verification.

The callback function for for_each_tag_name() didn't allow callers to
pass custom data to their callback functions. Add a new opaque pointer
to each_tag_name_fn's parameter to allow this.

Nguyễn Thái Ngọc Duy 3bb16a8bf2 tag, branch, for-each-ref: add --ignore-case for sorting and filtering
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.
