The git-for-each-ref(1) command doesn't provide a way to print root refs
i.e pseudorefs and HEAD with the regular "refs/" prefixed refs.
This commit adds a new option "--include-root-refs" to
git-for-each-ref(1). When used this would also print pseudorefs and HEAD
for the current worktree.

The flag 'FILTER_REFS_ALL' is a bit ambiguous, where ALL doesn't specify
if it means to contain refs from all worktrees or whether all types of
refs (regular, HEAD & pseudorefs) or all of the above.
Since here it is actually referring to all refs with the "refs/" prefix,
let's rename it to 'FILTER_REFS_REGULAR' to indicate that this is
specifically for regular refs.

forgotten include
* includes which could be replaced by a simple forward declaration of
some structs
* includes which aren't needed at all

Add two new public methods to 'ref-filter.h':
* 'print_formatted_ref_array()' which, given a format specification & array
of ref items, formats and prints the items to stdout.
* 'filter_and_format_refs()' which combines 'filter_refs()',
'ref_array_sort()', and 'print_formatted_ref_array()' into a single
function.
This consolidates much of the code used to filter and format refs in
'builtin/for-each-ref.c', 'builtin/tag.c', and 'builtin/branch.c', reducing
duplication and simplifying the future changes needed to optimize the filter
& format process.

Move the 'contains_cache' and 'no_contains_cache' used in filter_refs into
an 'internal' struct of the 'struct ref_filter'. In later patches, the
'struct ref_filter *' will be a common data structure across multiple
filtering functions. These caches are part of the common functionality the
filter struct will support, so they are updated to be internally accessible
wherever the filter is used.
The design used here mirrors what was introduced in 576de3d956
(unpack_trees: start splitting internal fields from public API, 2023-02-27)
for 'unpack_trees_options'.

Add an internal 'array_opts' struct to 'struct ref_format' containing
formatting options that pertain to the formatting of an entire ref array:
'max_count' and 'omit_empty'. These values are specified by the '--count'
and '--omit-empty' options, respectively, to 'for-each-ref'/'tag'/'branch'.
Storing these values in the 'ref_format' will simplify the consolidation of
ref array formatting logic across builtins in later patches.

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): 817.7 ms … 823.3 ms 10 runs
Benchmark 2: git.compile for-each-ref --format="%(objectname) %(refname)" --exclude refs/pull/
Time (mean ± σ): 106.6 ms ± 1.1 ms [User: 99.4 ms, System: 7.1 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.

We did not bother to clean up at all in `git branch` or `git tag`, and
`git for-each-ref` only cleans up a couple of members.
Add and call `ref_filter_clear()` when cleaning up a `struct
ref_filter`. Running this patch (without any test changes) indicates a
couple of now leak-free tests. This was found by running:
$ make SANITIZE=leak
$ make -C t GIT_TEST_PASSING_SANITIZE_LEAK=check GIT_TEST_OPTS=--immediate
(Note that the `reachable_from` and `unreachable_from` lists should be
cleaned as they are used. So this is just covering any case where we
might bail before running the reachability check.)

Provide a sane initialization value for `struct ref_filter`, which in a
subsequent patch will be used to initialize a new field.
In the meantime, ensure that the `ref_filter` struct used in the
test-helper's `cmd__reach()` is zero-initialized. The lack of
initialization is OK, since `commit_contains()` only looks at the single
`with_commit_tag_algo` field that *is* initialized directly above.
So this does not fix a bug, but rather prevents one from biting us in
the future.

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.

The headers 'diagnose.h', 'list-objects-filter-options.h',
'ref-filter.h' and 'remote.h' declare option parsing callback
functions with a 'struct option*' parameter, and 'revision.h' declares
an option parsing helper function taking 'struct parse_opt_ctx_t*' and
'struct option*' parameters. These headers all include
'parse-options.h', although they don't need any of the type
definitions from that header file. Furthermore,
'list-objects-filter-options.h' and 'ref-filter.h' also define some
OPT_* macros to initialize a 'struct option', but these don't
necessitate the inclusion of parse-options.h in these headers either,
because these macros are only expanded in source files.
Remove these unnecessary inclusions of parse-options.h and use forward
declarations to declare the necessary types.
After this patch none of the header files include parse-options.h
anymore.
With these changes, the build time after modifying only
parse-options.h is reduced by about 30%, and the number of targets
built is almost 20% less:

The for-each-ref family of commands invoke parsers immediately when
it sees each --sort=<atom> option, and die before even seeing the
other options on the command line when the <atom> is unrecognised.
Instead, accumulate them in a string list, and have them parsed into
a ref_sorting structure after the command line parsing is done. As
a consequence, "git branch --sort=bogus -h" used to fail to give the
brief help, which arguably may have been a feature, now does so,
which is more consistent with how other options work.
The patch is smaller than the actual extent of the "damage" to the
codebase, thanks to the fact that the original code consistently
used OPT_REF_SORT() macro to handle command line options. We only
needed to replace the variable used for the list, and implementation
of the callback function used in the macro.
The old rule was for the users of the API to:
- Declare ref_sorting and ref_sorting_tail variables;
- OPT_REF_SORT() macro will instantiate ref_sorting instance (which
may barf and die) and append it to the tail;
- Append to the tail each ref_sorting read from the configuration
by parsing in the config callback (which may barf and die);
- See if ref_sorting is null and use ref_sorting_default() instead.
Now the rule is not all that different but is simpler:
- Declare ref_sorting_options string list.
- OPT_REF_SORT() macro will append it to the string list;
- Append to the string list the sort key read from the
configuration;
- call ref_sorting_options() to turn the string list to ref_sorting
structure (which also deals with the default value).
As side effects, this change also cleans up a few issues:
- 95be717c (parse_opt_ref_sorting: always use with NONEG flag,
2019-03-20) muses that "git for-each-ref --no-sort" should simply
clear the sort keys accumulated so far; it now does.
- The implementation detail of "struct ref_sorting" and the helper
function parse_ref_sorting() can now be private to the ref-filter
API implementation.
- If you set branch.sort to a bogus value, the any "git branch"
invocation, not only the listing mode, would abort with the
original code; now it doesn't

characters after that first run of whitespace (i.e., the "rest"

Change the ref-filter sorting of detached HEAD to check the
FILTER_REFS_DETACHED_HEAD flag, instead of relying on the ref
description filled-in by get_head_description() to start with "(",
which in turn we expect to ASCII-sort before any other reference.
For context, we'd like the detached line to appear first at the start
of "git branch -l", e.g.:
$ git branch -l
* (HEAD detached at <hash>)
master
This doesn't change that, but improves on a fix made in
28438e84e04 (ref-filter: sort detached HEAD lines firstly, 2019-06-18)
and gives the Chinese translation the ability to use its preferred
punctuation marks again.
In Chinese the fullwidth versions of punctuation like "()" are
typically written as (U+FF08 fullwidth left parenthesis), (U+FF09
fullwidth right parenthesis) instead[1]. This form is used in both
po/zh_{CN,TW}.po in most cases where "()" is translated in a string.
Aside from that improvement to the Chinese translation, it also just
makes for cleaner code that we mark any special cases in the ref_array
we're sorting with flags and make the sort function aware of them,
instead of piggy-backing on the general-case of strcmp() doing the
right thing.
As seen in the amended tests this made reverse sorting a bit more
consistent. Before this we'd sometimes sort this message in the
middle, now it's consistently at the beginning or end, depending on
whether we're doing a normal or reverse sort. Having it at the end
doesn't make much sense either, but at least it behaves consistently
now. A follow-up commit will make this behavior under reverse sorting
even better.
I'm removing the "TRANSLATORS" comments that were in the old code
while I'm at it. Those were added in d4919bb288e (ref-filter: move
get_head_description() from branch.c, 2017-01-10). I think it's
obvious from context, string and translation memory in typical
translation tools that these are the same or similar string.

Change the reverse/ignore_case/version sort flags in the ref_sorting
struct into a bitfield. Having three of them was already a bit
unwieldy, but it would be even more so if another flag needed a
function like ref_sorting_icase_all() introduced in
76f9e569adb (ref-filter: apply --ignore-case to all sorting keys,
2020-05-03).
A follow-up change will introduce such a flag, so let's move this over
to a bitfield. Instead of using the usual '#define' pattern I'm using
the "enum" pattern from builtin/rebase.c's b4c8eb024af (builtin
rebase: support --quiet, 2018-09-04).
Perhaps there's a more idiomatic way of doing the "for each in list
amend mask" pattern than this "mask/on" variable combo. This function
doesn't allow us to e.g. do any arbitrary changes to the bitfield for
multiple flags, but I think in this case that's fine. The common case
is that we're calling this with a list of one.

"git branch" and other "for-each-ref" variants accepted multiple
--sort=<key> options in the increasing order of precedence, but it
had a few breakages around "--ignore-case" handling, and tie-breaking
with the refname, which have been fixed.
* jk/for-each-ref-multi-key-sort-fix:
ref-filter: apply fallback refname sort only after all user sorts
ref-filter: apply --ignore-case to all sorting keys
|
|
All of the ref-filter users (for-each-ref, branch, and tag) take an
--ignore-case option which makes filtering and sorting case-insensitive.
However, this option was applied only to the first element of the
ref_sorting list. So:
git for-each-ref --ignore-case --sort=refname
would do what you expect, but:
git for-each-ref --ignore-case --sort=refname --sort=taggername
would sort the primary key (taggername) case-insensitively, but sort the
refname case-sensitively. We have two options here:
- teach callers to set ignore_case on the whole list
- replace the ref_sorting list with a struct that contains both the
list of sorting keys, as well as options that apply to _all_
keys
I went with the first one here, as it gives more flexibility if we later
want to let the users set the flag per-key (presumably through some
special syntax when defining the key; for now it's all or nothing
through --ignore-case).
The new test covers this by sorting on both tagger and subject
case-insensitively, which should compare "a" and "A" identically, but
still sort them before "b" and "B". We'll break ties by sorting on the
refname to give ourselves a stable output (this is actually supposed to
be done automatically, but there's another bug which will be fixed in
the next commit).

We renamed the actual data structure in 910650d2f8 (Rename sha1_array to
oid_array, 2017-03-31), but the file is still called sha1-array. Besides
being slightly confusing, it makes it more annoying to grep for leftover
occurrences of "sha1" in various files, because the header is included
in so many places.
Let's complete the transition by renaming the source and header files
(and fixing up a few comment references).
I kept the "-" in the name, as that seems to be our style; cf.
fc1395f4a4 (sha1_file.c: rename to use dash in file name, 2018-04-10).
We also have oidmap.h and oidset.h without any punctuation, but those
are "struct oidmap" and "struct oidset" in the code. We _could_ make
this "oidarray" to match, but somehow it looks uglier to me because of
the length of "array" (plus it would be a very invasive patch for little
gain).

The "--sort" parameter of for-each-ref, etc, does not handle negation,
and instead returns an error to the parse-options code. But neither

confused:

clear the list, which would make it consistent with other list-like
options (i.e., anything that uses OPT_STRING_LIST currently).
Unfortunately that's a bit tricky due to the way the ref-filter code
works. But in the meantime, let's at least make the error a little less
confusing:
- switch to using PARSE_OPT_NONEG in the option definition, which will
cause the options code to produce a useful message
- since this was cut-and-pasted to four different spots, let's define
a single OPT_REF_SORT() macro that we can use everywhere
- the callback can use BUG_ON_OPT_NEG() to make sure the correct flags
are used (incidentally, this also satisfies -Wunused-parameters,
since we're now looking at "unset")
- expand the comment into a NEEDSWORK to make it clear that the
direction is right, but the details need to be worked out

In preparation for callers constructing their own ref_array
structs, let's move our own internal push operation into its
own function.
While we're at it, we can replace REALLOC_ARRAY() with
ALLOC_GROW(), which should give the growth operation
amortized linear complexity (as opposed to growing by one,
which is potentially quadratic, though in-place realloc
growth often makes this faster in practice).

Internally we store a "struct object_id", and all of our
callers have one to pass us. But we insist that they peel it
to its bare-sha1 hash, which we then hashcpy() into place.
Let's pass it around as an object_id, which future-proofs us
for a post-sha1 world.

This is a first step in removing die() calls from ref-filter
formatting logic, so that it could be used by other commands
that do not want to die during formatting process.
die() calls related to bugs in code will not be touched in this patch.
Everything would be the same for show_ref_array_item() users.
But, if you want to deal with errors by your own, you could invoke
format_ref_array_item(). It means that you need to print everything
(the result and errors) on your side.
This commit changes signature of format_ref_array_item() by adding
return value and strbuf parameter for errors, and adjusts
its callers. While at it, reduce the scope of the out-variable.

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.

The parse_ref_filter_atom() function really shouldn't be
exposed outside of ref-filter.c; its return value is an
integer index into an array that is private in that file.
Since the previous commit removed the sole external caller
(and replaced it with a public function at a more
appropriately level), we can just make this static.

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.

Calling verify_ref_format() doesn't just confirm that the
format is sane; it actually sets some global variables that
will be used later when formatting the refs. These logically
should belong to the ref_format, which would make it
possible to use multiple formats within a single program
invocation.
Let's move one such flag into the ref_format struct. There
are still others that would need to be moved before it would
be safe to use multiple formats, but this commit gives a
blueprint for how that should look.

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.

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.

To allow column display, we will need to first render the output in a
string list to allow print_columns() to compute the proper size of
each column before starting the actual output. Introduce the function
format_ref_array_item() that does the formatting of a ref_array_item
to an strbuf.
show_ref_array_item() is kept as a convenience wrapper around it which
obtains the strbuf and prints it the standard output.
