"git ls-files --format" can be used to format the output of
multiple file entries in the index, while "git ls-tree --format"
can be used to format the contents of a tree object. However,
the current set of %(objecttype), "(objectsize)", and
"%(objectsize:padded)" atoms supported by "git ls-files --format"
is a subset of what is available in "git ls-tree --format".
Users sometimes need to establish a unified view between the index
and tree, which can help with comparison or conversion between the two.
Therefore, this patch adds the missing atoms to "git ls-files --format".
"%(objecttype)" can be used to retrieve the object type corresponding
to a file in the index, "(objectsize)" can be used to retrieve the
object size corresponding to a file in the index, and "%(objectsize:padded)"
is the same as "(objectsize)", except with padded format.

The glossary defines 'ref' as the official name of the thing,

that most everybody uses <ref>, not <reference>. In addition,
the page already says <ref> in its SYNOPSIS section for the

Strictly speaking, many references of these should be updated to
<commit> after adding an explanation on how these <commit>s are
discovered (i.e. we take <rev>, <glob>, or <ref> and starting from
these commits, follow their ancestry or reflog entries to list

Allow users to be more selective over which refs to pack by adding an
--include option to git-pack-refs.
The existing options allow some measure of selectivity. By default
git-pack-refs packs all tags. --all can be used to include all refs,
and the previous commit added the ability to exclude certain refs with
--exclude.
While these knobs give the user some selection over which refs to pack,
it could be useful to give more control. For instance, a repository may
have a set of branches that are rarely updated and would benefit from
being packed. --include would allow the user to easily include a set of
branches to be packed while leaving everything else unpacked.

The output of git-fetch(1) is obviously designed for consumption by
users, only: we neatly columnize data, we abbreviate reference names, we
print neat arrows and we don't provide information about actual object
IDs that have changed. This makes the output format basically unusable
in the context of scripted invocations of git-fetch(1) that want to
learn about the exact changes that the command performs.
Introduce a new machine-parseable "porcelain" output format that is
supposed to fix this shortcoming. This output format is intended to
provide information about every reference that is about to be updated,
the old object ID that the reference has been pointing to and the new
object ID it will be updated to. Furthermore, the output format provides
the same flags as the human-readable format to indicate basic conditions
for each reference update like whether it was a fast-forward update, a
branch deletion, a rejected update or others.
The output format is quite simple:
```
<flag> <old-object-id> <new-object-id> <local-reference>\n
```
We assume two conditions which are generally true:
- The old and new object IDs have fixed known widths and cannot
contain spaces.
- References cannot contain newlines.
With these assumptions, the output format becomes unambiguously
parseable. Furthermore, given that this output is designed to be
consumed by scripts, the machine-readable data is printed to stdout
instead of stderr like the human-readable output is. This is mostly done
so that other data printed to stderr, like error messages or progress
meters, don't interfere with the parseable data.
A notable ommission here is that the output format does not include the
remote from which a reference was fetched, which might be important
information especially in the context of multi-remote fetches. But as
such a format would require us to print the remote for every single
reference update due to parallelizable fetches it feels wasteful for the
most likely usecase, which is when fetching from a single remote.
In a similar spirit, a second restriction is that this cannot be used
with `--recurse-submodules`. This is because any reference updates would
be ambiguous without also printing the repository in which the update
happens.
Considering that both multi-remote and submodule fetches are user-facing
features, using them in conjunction with `--porcelain` that is intended
for scripting purposes is likely not going to be useful in the majority
of cases. With that in mind these restrictions feel acceptable. If
usecases for either of these come up in the future though it is easy
enough to add a new "porcelain-v2" format that adds this information.

The '--all' option of git-push built-in cmd support to push all branches
(refs under refs/heads) to remote. Under the usage, a user can easlily
work in some scenarios, for example, branches synchronization and batch
upload.
The '--all' was introduced for a long time, meanwhile, git supports to
customize the storage location under "refs/". when a new git user see
the usage like, 'git push origin --all', we might feel like we're
pushing _all_ the refs instead of just branches without looking at the
documents until we found the related description of it or '--mirror'.
To ensure compatibility, we cannot rename '--all' to another name
directly, one way is, we can try to add a new option '--heads' which be
identical with the functionality of '--all' to let the user understand
the meaning of representation more clearly. Actually, We've more or less
named options this way already, for example, in 'git-show-ref' and 'git
ls-remote'.
At the same time, we fix a related issue about the wrong help
information of '--all' option in code and add some test cases in
t5523, t5543 and t5583.

Earlier, 47cfc9bd (attr: add flag `--source` to work with tree-ish,
2023-01-14) taught "git check-attr" the "--source=<tree>" option to
allow it to read attribute files from a tree-ish, but did so only
for the command. Just like "check-attr" users wanted a way to use
attributes from a tree-ish and not from the working tree files,
users of other commands (like "git diff") would benefit from the
same.
Undo most of the UI change the commit made, while keeping the
internal logic to read attributes from a given tree-ish. Expose the
internal logic via a new "--attr-source=<tree>" command line option
given to "git", so that it can be used with any git command that
runs as part of the main git process.
Additionally, add an environment variable GIT_ATTR_SOURCE that is set
when --attr-source is passed in, so that subprocesses use the same value

The original doc-diff script set SOURCE_DATE_EPOCH to make asciidoc's
output deterministic. Otherwise, the mtime of the source files would end
up in the footer of the manpage, causing noisy and uninteresting diff
hunks.
But this has been unused since 28fde3a1f4 (doc: set actual revdate for
manpages, 2023-04-13), as the footer uses the externally-specified
GIT_DATE instead (that needs to be set consistently, too, which it now
is as of the previous commit).
Asciidoc sets several automatic attributes based on the mtime (or manual
epoch), so it's still possible to write a document that would need
SOURCE_DATE_EPOCH set to be deterministic. But if we wrote such a thing,
it's probably a mistake, and we're better off having doc-diff loudly
show it.

Sergey Organov noticed and reported "--patch --no-patch --raw"
behaves differently from just "--raw". It turns out that there are
a few interesting bugs in the implementation and documentation.
* First, the documentation for "--no-patch" was unclear that it
could be read to mean "--no-patch" countermands an earlier
"--patch" but not other things. The intention of "--no-patch"
ever since it was introduced at d09cd15d (diff: allow --no-patch
as synonym for -s, 2013-07-16) was to serve as a synonym for
"-s", so "--raw --patch --no-patch" should have produced no
output, but it can be (mis)read to allow showing only "--raw"
output.
* Then the interaction between "-s" and other format options were
poorly implemented. Modern versions of Git uses one bit each to
represent formatting options like "--patch", "--stat" in a single
output_format word, but for historical reasons, "-s" also is
represented as another bit in the same word. This allows two
interesting bugs to happen, and we have both X-<.
(1) After setting a format bit, then setting NO_OUTPUT with "-s",
the code to process another "--<format>" option drops the
NO_OUTPUT bit to allow output to be shown again. However,
the code to handle "-s" only set NO_OUTPUT without unsetting
format bits set earlier, so the earlier format bit got
revealed upon seeing the second "--<format>" option. This is
the problem Sergey observed.
(2) After setting NO_OUTPUT with "-s", code to process
"--<format>" option can forget to unset NO_OUTPUT, leaving
the command still silent.
It is tempting to change the meaning of "--no-patch" to mean
"disable only the patch format output" and reimplement "-s" as "not
showing anything", but it would be an end-user visible change in
behavior. Let's fix the interactions of these bits to first make
"-s" work as intended.
The fix is conceptually very simple.
* Whenever we set DIFF_FORMAT_FOO because we saw the "--foo"
option (e.g. DIFF_FORMAT_RAW is set when the "--raw" option is
given), we make sure we drop DIFF_FORMAT_NO_OUTPUT. We forgot to
do so in some of the options and caused (2) above.
* When processing "-s" option, we should not just set
DIFF_FORMAT_NO_OUTPUT bit, but clear other DIFF_FORMAT_* bits.
We didn't do so and retained format bits set by options
previously seen, causing (1) above.
It is even more tempting to lose NO_OUTPUT bit and instead take
output_format word being 0 as its replacement, but that would break
the mechanism "git show" uses to default to "--patch" output, where
the distinction between telling the command to be silent with "-s"
and having no output format specified on the command line matters,
and an explicit output format given on the command line should not
be "combined" with the default "--patch" format.
So, while we cannot lose the NO_OUTPUT bit, as a follow-up work, we
may want to replace it with OPTION_GIVEN bit, and
* make "--patch", "--raw", etc. set DIFF_FORMAT_$format bit and
DIFF_FORMAT_OPTION_GIVEN bit on for each format. "--no-raw",
etc. will set off DIFF_FORMAT_$format bit but still record the
fact that we saw an option from the command line by setting
DIFF_FORMAT_OPTION_GIVEN bit.
* make "-s" (and its synonym "--no-patch") clear all other bits
and set only the DIFF_FORMAT_OPTION_GIVEN bit on.
which I suspect would make the code much cleaner without breaking
any end-user expectations.
Once that is in place, transitioning "--no-patch" to mean the
counterpart of "--patch", just like "--no-raw" only defeats an
earlier "--raw", would be quite simple at the code level. The
social cost of migrating the end-user expectations might be too
great for it to be worth, but at least the "GIVEN" bit clean-up
alone may be worth it.

Earlier we changed the manual page formatting machinery to use the
dates from the commit the documentation source was taken from,
instead of the date the manual page was produced. When "doc-diff"
compares two commits from different dates, the different dates from
the two commits would result in unnecessary differences in the
output because of the change.
Compensate by setting a fixed date when "doc-diff" formats the pages
to be compared to work around this issue.
