Update the ref sorting functions of 'ref-filter.c' so that when date fields
are specified with a format string (such as in 'git for-each-ref
--sort=creatordate:<something>'), they are sorted by their formatted string
value rather than by the underlying numeric timestamp. Currently, date
fields are always sorted by timestamp, regardless of whether formatting
information is included in the '--sort' key.
Leaving the default (unformatted) date sorting unchanged, sorting by the
formatted date string adds some flexibility to 'for-each-ref' by allowing
for behavior like "sort by year, then by refname within each year" or "sort
by time of day". Because the inclusion of a format string previously had no
effect on sort behavior, this change likely will not affect existing usage
of 'for-each-ref' or other ref listing commands.
Additionally, update documentation & tests to document the new sorting
mechanism.

"git for-each-ref --no-sort" still sorted the refs alphabetically
which paid non-trivial cost. It has been redefined to show output
in an unspecified order, to allow certain optimizations to take
advantage of.
* vd/for-each-ref-unsorted-optimization:
t/perf: add perf tests for for-each-ref

In most builtins ('rev-parse <revision>^{}', 'show-ref --dereference'),
"dereferencing" a tag refers to a recursive peel of the tag object. Unlike
these cases, the dereferencing prefix ('*') in 'for-each-ref' format
specifiers triggers only a single, non-recursive dereference of a given tag
object. For most annotated tags, a single dereference is all that is needed
to access the tag's associated commit or tree; "recursive" and
"non-recursive" dereferencing are functionally equivalent in these cases.
However, nested tags (annotated tags whose target is another annotated tag)
dereferenced once return another tag, where a recursive dereference would
return the commit or tree.
Currently, if a user wants to filter & format refs and include information
about a recursively-dereferenced tag, they can do so with something like
'cat-file --batch-check':
git for-each-ref --format="%(objectname)^{} %(refname)" <pattern> |
git cat-file --batch-check="%(objectname) %(rest)"
But the combination of commands is inefficient. So, to improve the
performance of this use case and align the defererencing behavior of
'for-each-ref' with that of other commands, update the ref formatting code
to use the peeled tag (from 'peel_iterated_oid()') to populate '*' fields
rather than the tag's immediate target object (from 'get_tagged_oid()').
Additionally, add a test to 't6300-for-each-ref' to verify new nested tag
behavior and update 't6302-for-each-ref-filter.sh' to print the correct
value for nested dereferenced fields.

Add mailmap support to ref-filter formats which are similar in
pretty. This support is such that the following pretty placeholders are
equivalent to the new ref-filter atoms:
%aN = authorname:mailmap
%cN = committername:mailmap
%aE = authoremail:mailmap
%aL = authoremail:mailmap,localpart
%cE = committeremail:mailmap
%cL = committeremail:mailmap,localpart
Additionally, mailmap can also be used with ":trim" option for email by
doing something like "authoremail:mailmap,trim".
The above also applies for the "tagger" atom, that is,
"taggername:mailmap", "taggeremail:mailmap", "taggeremail:mailmap,trim"
and "taggername:mailmap,localpart".
The functionality of ":trim" and ":localpart" remains the same. That is,
":trim" gives the email, but without the angle brackets and ":localpart"
gives the part of the email before the '@' character (if such a
character is not found then we directly grab everything between the
angle brackets).

Enumerating refs in the packed-refs file, while excluding refs that

ref-filter: clear reachable list pointers after freeing
ref-filter.h: provide `REF_FILTER_INIT`
refs.c: rename `ref_filter`
When using `for-each-ref`, it is sometimes convenient for the caller to
be able to exclude certain parts of the references.
For example, if there are many `refs/__hidden__/*` references, the
caller may want to emit all references *except* the hidden ones.
Currently, the only way to do this is to post-process the output, like:
$ git for-each-ref --format='%(refname)' | grep -v '^refs/hidden/'
Which is do-able, but requires processing a potentially large quantity
of references.
Teach `git for-each-ref` a new `--exclude=<pattern>` option, which
excludes references from the results if they match one or more excluded
patterns.
This patch provides a naive implementation where the `ref_filter` still
sees all references (including ones that it will discard) and is left to
check whether each reference matches any excluded pattern(s) before
emitting them.
By culling out references we know the caller doesn't care about, we can
avoid allocating memory for their storage, as well as spending time
sorting the output (among other things). Even the naive implementation
provides a significant speed-up on a modified copy of linux.git (that
has a hidden ref pointing at each commit):
$ hyperfine \
'git.compile for-each-ref --format="%(objectname) %(refname)" | grep -vE "[0-9a-f]{40} refs/pull/"' \
'git.compile for-each-ref --format="%(objectname) %(refname)" --exclude refs/pull/'
Benchmark 1: git.compile for-each-ref --format="%(objectname) %(refname)" | grep -vE "[0-9a-f]{40} refs/pull/"
Time (mean ± σ): 820.1 ms ± 2.0 ms [User: 703.7 ms, System: 152.0 ms]

Range (min … max): 104.7 ms … 109.1 ms 27 runs
Summary
'git.compile for-each-ref --format="%(objectname) %(refname)" --exclude refs/pull/' ran
7.69 ± 0.08 times faster than 'git.compile for-each-ref --format="%(objectname) %(refname)" | grep -vE "[0-9a-f]{40} refs/pull/"'
Subsequent patches will improve on this by avoiding visiting excluded
sections of the `packed-refs` file in certain cases.

The previous change implemented the ahead_behind() method, including an
algorithm to compute the ahead/behind values for a number of commit tips
relative to a number of commit bases. Now, integrate that algorithm as
part of 'git for-each-ref' hidden behind a new format atom,
ahead-behind. This naturally extends to 'git branch' and 'git tag'
builtins, as well.
This format allows specifying multiple bases, if so desired, and all
matching references are compared against all of those bases. For this
reason, failing to read a reference provided from these atoms results in
an error.
In order to translate the ahead_behind() method information to the
format output code in ref-filter.c, we must populate arrays of
ahead_behind_count structs. In struct ref_array, we store the full array
that will be passed to ahead_behind(). In struct ref_array_item, we
store an array of pointers that point to the relvant items within the
full array. In this way, we can pull all relevant ahead/behind values
directly when formatting output for a specific item. It also ensures the
lifetime of the ahead_behind_count structs matches the time that the
array is being used.
Add specific tests of the ahead/behind counts in t6600-test-reach.sh, as
it has an interesting repository shape. In particular, its merging
strategy and its use of different commit-graphs would demonstrate over-
counting if the ahead_behind() method did not already account for that
possibility.
Also add tests for the specific for-each-ref, branch, and tag builtins.
In the case of 'git tag', there are intersting cases that happen when
some of the selected tips are not commits. This requires careful logic
around commits_nr in the second loop of filter_ahead_behind(). Also, the
test in t7004 is carefully located to avoid being dependent on the GPG
prereq. It also avoids using the test_commit helper, as that will add
ticks to the time and disrupt the expected timestamps in later tag
tests.
Also add performance tests in a new p1300-graph-walks.sh script. This
will be useful for more uses in the future, but for now compare the
ahead-behind counting algorithm in 'git for-each-ref' to the naive
implementation by running 'git rev-list --count' processes for each
input.
For the Git source code repository, the improvement is already obvious:
Test this tree
---------------------------------------------------------------
1500.2: ahead-behind counts: git for-each-ref 0.07(0.07+0.00)
1500.3: ahead-behind counts: git branch 0.07(0.06+0.00)
1500.4: ahead-behind counts: git tag 0.07(0.06+0.00)
1500.5: ahead-behind counts: git rev-list 1.32(1.04+0.27)
But the standard performance benchmark is the Linux kernel repository,
which demosntrates a significant improvement:
Test this tree
---------------------------------------------------------------
1500.2: ahead-behind counts: git for-each-ref 0.27(0.24+0.02)
1500.3: ahead-behind counts: git branch 0.27(0.24+0.03)
1500.4: ahead-behind counts: git tag 0.28(0.27+0.01)
1500.5: ahead-behind counts: git rev-list 4.57(4.03+0.54)
The 'git rev-list' test exists in this change as a demonstration, but it
will be removed in the next change to avoid wasting time on this
comparison.

When a user wishes to input a large list of patterns to 'git
for-each-ref' (likely a long list of exact refs) there are frequently
system limits on the number of command-line arguments.
Add a new --stdin option to instead read the patterns from standard
input. Add tests that check that any unrecognized arguments are
considered an error when --stdin is provided. Also, an empty pattern
list is interpreted as the complete ref set.
When reading from stdin, we populate the filter.name_patterns array
dynamically as opposed to pointing to the 'argv' array directly. This is
simple when using a strvec, as it is NULL-terminated in the same way. We
then free the memory directly from the strvec.

Add new formatting option `%(raw)`, which will print the raw
object data without any changes. It will help further to migrate
all cat-file formatting logic from cat-file to ref-filter.
The raw data of blob, tree objects may contain '\0', but most of
the logic in `ref-filter` depends on the output of the atom being
text (specifically, no embedded NULs in it).
E.g. `quote_formatting()` use `strbuf_addstr()` or `*._quote_buf()`
add the data to the buffer. The raw data of a tree object is
`100644 one\0...`, only the `100644 one` will be added to the buffer,
which is incorrect.
Therefore, we need to find a way to record the length of the
atom_value's member `s`. Although strbuf can already record the
string and its length, if we want to replace the type of atom_value's
member `s` with strbuf, many places in ref-filter that are filled
with dynamically allocated mermory in `v->s` are not easy to replace.
At the same time, we need to check if `v->s == NULL` in
populate_value(), and strbuf cannot easily distinguish NULL and empty
strings, but c-style "const char *" can do it. So add a new member in
`struct atom_value`: `s_size`, which can record raw object size, it
can help us add raw object data to the buffer or compare two buffers
which contain raw object data.
Note that `--format=%(raw)` cannot be used with `--python`, `--shell`,
`--tcl`, and `--perl` because if the binary raw data is passed to a
variable in such languages, these may not support arbitrary binary data
in their string variable type.

upstream branch on the remote repository, but also the name of the
remote.
This patch offers the new suffix :remotename for the upstream and for
the push atoms, allowing to show exactly that. Example:
$ cat .git/config
...
[remote "origin"]
url = https://where.do.we.come/from
fetch = refs/heads/*:refs/remote/origin/*
[remote "hello-world"]
url = https://hello.world/git
fetch = refs/heads/*:refs/remote/origin/*
pushURL = hello.world:git
push = refs/heads/*:refs/heads/*
[branch "master"]
remote = origin
pushRemote = hello-world
...
$ git for-each-ref \
--format='%(upstream) %(upstream:remotename) %(push:remotename)' \
refs/heads/master
refs/remotes/origin/master origin hello-world
The implementation chooses *not* to DWIM the push remote if no explicit
push remote was configured; The reason is that it is possible to DWIM this
by using
%(if)%(push:remotename)%(then)
%(push:remotename)
%(else)
%(upstream:remotename)
%(end)
while it would be impossible to "un-DWIM" the information in case the
caller is really only interested in explicit push remotes.
While `:remote` would be shorter, it would also be a bit more ambiguous,
and it would also shut the door e.g. for `:remoteref` (which would
obviously refer to the corresponding ref in the remote repository).
Note: the dashless, non-CamelCased form `:remotename` follows the
example of the `:trackshort` example.

* jk/ui-color-always-to-auto-maint:
color: make "always" the same as "auto" in config
provide --color option for all ref-filter users
t3205: use --color instead of color.branch=always
t3203: drop "always" color test
t6006: drop "always" color config tests
t7502: use diff.noprefix for --verbose test
t7508: use test_terminal for color output
t3701: use test-terminal to collect color output
t4015: prefer --color to -c color.diff=always
test-terminal: set TERM=vt100
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).

Fill trailer_opts with "unfold" and "only" to match the sub-arguments
given to the "%(trailers)" atom. Then, let's use the filled trailer_opts
instance with 'format_trailers_from_commit' in order to format trailers
in the desired manner.

"'<string>'"-style quoting is not appropriate when quoting literal
strings in the "Documentation/" subtree.
In preparation for adding additional information to this section of

instead.

The documentation makes reference to 'contents:trailers' as an example
to dig the trailers out of a commit. 'trailers' is an unmentioned
alternative, which is treated as an alias of 'contents:trailers'.
Since 'trailers' is easier to type, prefer that as the designated way to
dig out trailers information.

Documentation/git-for-each-ref: clarify peeling of tags for --format
Documentation: use proper wording for ref format strings
`*` in format strings means peeling of tag objects so that object field
names refer to the object that the tag object points at, instead of the
tag object itself.
Currently, this is documented using grammar that is clearly inspired by
classical latin, though missing more than an article in order to be
classical english.
Try and straighten that explanation out a bit.

Various commands list refs and allow to use a format string for the
output that interpolates from the ref as well as the object it points
at (for-each-ref; branch and tag in list mode).
Currently, the documentation talks about interpolating from the object.
This is confusing because a ref points to an object but not vice versa,
so the object cannot possible know %(refname), for example. Thus, this is
wrong independent of refs being objects (one day, maybe) or not.
Change the wording to make this clearer (and distinguish it from formats
for the log family).

The documentation for the %(color) placeholder refers to the
color.branch.* config for more details. But those details
moved to their own section in b92c1a28f
(Documentation/config.txt: describe 'color' value type in
the "Values" section, 2015-03-03). Let's update our
pointer. We can steal the text from 30cfe72d3 (pretty: fix
document link for color specification, 2016-10-11), which
fixed the same problem in a different place.
While we're at it, let's give an example, which makes the
syntax much more clear than just the text.

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.
