Justin Tobler 17215675b5 builtin/repo: add keyvalue and nul format for structure stats
All repository structure stats are outputted in a human-friendly table
form. This format is not suitable for machine parsing. Add a --format
option that supports three output modes: `table`, `keyvalue`, and `nul`.
The `table` mode is the default format and prints the same table output
as before.

With the `keyvalue` mode, each line of output contains a key-value pair
of a repository stat. The '=' character is used to delimit between keys
and values. The `nul` mode is similar to `keyvalue`, but key-values are
delimited by a NUL character instead of a newline. Also, instead of a
'=' character to delimit between keys and values, a newline character is
used. This allows stat values to support special characters without
having to cquote them. These two new modes provides output that is more
machine-friendly.

Justin Tobler eb5cf58ffc builtin/repo: add object counts in structure output
The amount of objects in a repository can provide insight regarding its
shape. To surface this information, use the path-walk API to count the
number of reachable objects in the repository by object type. All
regular references are used to determine the reachable set of objects.
The object counts are appended to the same table containing the
reference information.

Justin Tobler bbb2b93348 builtin/repo: introduce structure subcommand
The structure of a repository's history can have huge impacts on the
performance and health of the repository itself. Currently, Git lacks a
means to surface repository metrics regarding its structure/shape via a
single command. Acquiring this information requires users to be familiar
with the relevant data points and the various Git commands required to
surface them. To fill this gap, supplemental tools such as git-sizer(1)
have been developed.

To allow users to more readily identify repository structure related
information, introduce the "structure" subcommand in git-repo(1). The
goal of this subcommand is to eventually provide similar functionality
to git-sizer(1), but natively in Git.

The initial version of this command only iterates through all references
in the repository and tracks the count of branches, tags, remote refs,
and other reference types. The corresponding information is displayed in
a human-friendly table formatted in a very similar manner to
git-sizer(1). The width of each table column is adjusted automatically
to satisfy the requirements of the widest row contained.

Subsequent commits will surface additional relevant data points to
output and also provide other more machine-friendly output formats.

Ramsay Jones 1c1fc86d55 doc: add large-object-promisors.adoc to the docs build
Commit 5040f9f164 ("doc: add technical design doc for large object
promisors", 2025-02-18) added the large object promisors document
as a technical document (with a '.txt' extension). The merge commit
2c6fd30198 ("Merge branch 'cc/lop-remote'", 2025-03-05) seems to
have renamed the file with an '.adoc' extension.

Despite the '.adoc' extension, this document was not being formatted
by asciidoc(tor) as part of the docs build. In order to do so, add
the document to the make and meson build files.

Having added the document to the build, asciidoc and asciidoctor find
(slightly different) problems with the syntax of the input document.

The first set of warnings (only issued by asciidoc) relate to some
'section title out of sequence: expected level 3, got level 4'. This
document uses 'setext' style of section headers, using a series of
underline characters, where the character used denotes the level of
the title. From document title to level 5 (see [1]), these characters
are =, -, ~, ^, +. This does not seem to fit the error message, which
implies that those characters denote levels 0 -> 4. Replacing the headings
underlined with '+' by the '^' character eliminates these warnings.

The second set of warnings (only issued by asciidoctor) relate to some
headings which seem to use both arabic and roman numerals as part of
a single 'list' sequence. This elicited either 'unterminated listing
block' or (for example) 'list item index: expected I, got II' warnings.
In order not to mix arabic and roman numerals, remove the numeral from
the '0) Non goals' heading.  Similarly, the remaining roman numeral
entries had the ')' removed and turned into regular headings with I, II,
III ... at the beginning.

Ramsay Jones b770ed9545 doc: commit-graph.adoc: fix up some formatting
The formatting markup syntax used in this document (markdown?) is not
interpreted correctly by asciidoc or asciidoctor. The main problem is
the use of a '## ' prefix markup for some sub-headings, along with the
use of '```' code markup and some missing literal blocks.

In order to improve the (html) document formatting:

  - replace the '## ' prefix sub-title syntax with the '~~' underlining
    syntax for the relevant sub-headings.
  - replace the '```' code markup, which causes asciidoc(tor) to simply
    remove the marked up text, with a literal block '----' markup.
  - the second ascii diagram, in the 'Merging commit-graph files'
    section, is not rendered correctly by asciidoctor (asciidoc is fine)
    so enclose it in a '....' block.

Ramsay Jones 45e8b7c2d4 doc: sparse-checkout.adoc: fix asciidoc warnings
Both asciidoc and asciidoctor issue warnings about 'list item index:
expected n got n-1' for n=1->7 on lines 928, 931, 951, 974, 980, 1033
and 1049. In asciidoc, numbered lists must start at one, whereas this
file has a list starting at zero. Also, asciidoc and asciidoctor warn
about 'section title out of sequence: expected level 1, got level 2'
on line 17. (asciidoc only complains about the first instance of this,
while asciidoctor complains about them all, on lines 95, 258, 303, 316,
545, 612, 752, 824, 895, 923 and 1053). These warnings stem from the
section titles not being correctly nested within a document/chapter
title.

In order to address the first set of warnings, simply renumber the list
from one to seven, rather than zero to six. Fortunately, this does not
require altering additional text, since the enumeration of 'Known Bugs'
is not referred to anywhere else in the document.

In order to address the second set of warnings, change the section title
syntax from '=== title ===' to '== title ==', effectively reducing the
nesting level of the title by one. Also, some apparent (sub-)titles are
not marked up with sub-title syntax, so add some '=== ' prefix(s) to the
relevant headings.

In addition to the warnings, address some other formatting issues:

  - the use of heavily nested unordered lists is not reflected in the
    output (making the file totally unreadable) because each level of
    nesting requires a different syntax. (i.e. replace '*' with '**'
    for the second level, '*' with '***' for the third level, etc.)
  - make use of literal blocks and manual indentation to get asciidoc
    and asciidoctor to display even remotely similar output.
  - make use of labelled lists, in some places, to get a similar looking
    output to the input, for both asciidoc and asciidoctor.
  - replace the trailing space in: `git grep ${SEARCH_TERM} OLDREV `
    otherwise the entire line in which that appears is removed from
    the output.

Ramsay Jones 4fa0e4d02c doc: remembering-renames.adoc: fix asciidoc warnings
Both asciidoc and ascidoctor issue warnings about 'list item index:
expected n got n-1' for n=1->9 on lines 13, 15, 17, 20, 23, 25, 29,
31 and 33. In asciidoc, numbered lists must start at one, whereas this
file has a list starting at zero. Also, asciidoc and asciidoctor warn
about 'section title out of sequence: expected level 1, got level 2'
on line 38. (asciidoc only complains about the first instance of this,
while asciidoctor complains about them all, on lines 94, 141, 142,
184, 185, 257, 288, 289, 290, 397, 424, 485, 486 and 487). These
warnings stem from the section titles not being correctly nested within
a document/chapter title.

In order to address the first set of warnings, simply renumber the list
from one to nine, rather than zero to eight. This also requires altering
the text which refers to the section numbers, including other section
titles.

In order to address the second set of warnings, change the section title
syntax from '=== title ===' to '== title ==', effectively reducing the
nesting level of the title by one. Also, some of the titles are given
over multiple lines (they are very long), with an title '===' prefix
on each line. This leads to them being treated as separate sections
with no body text (as you can see from the line numbers given for the
asciidoctor warnings, above). So, for these titles, turn them into a
single (long) line of text.

In addition to the warnings, address some other formatting issues:

  - the ascii branch diagrams didn't format correctly on asciidoctor
    so include them in a literal block.
  - several blocks of text were intended to be formatted 'as is' but
    were not included in a literal block.
  - in section 8, format the (A)->(D) in the text description as a
    literal with `` marks, since (C) is rendered as a copyright
    symbol in html otherwise.
  - in section 9, a sub-list of two items is not formatted as such.
    change the '*' introducer to '**' to correct the sub-list format.

Julia Evans d8942ac494 doc: git-pull: delete the example
From user feedback: this example is confusing because it implies that
`git pull` will run `git merge` by default, but the default is
`--ff-only`.

We could instead show an example of a fast-forward merge, but that may
not add a lot since fast-forward merges are relatively simple. This lets
us keep the description short.

Julia Evans 59b28f928b doc: git-pull: clarify options for integrating remote branch
From user feedback:

- One user is confused about the current default ("I was convinced that
  the git default was still to merge on pull")
- One user is confused about why "git fetch" isn't mentioned earlier
- One user says they always forget what the arguments to `git pull` are
  and that it's not immediately obvious that `--no-rebase` means "merge"
- One user wants `--ff-only` to be mentioned

Resolve this by listing the options for integrating the the remote
branch. This should help users figure out at a glance which one they
want to do, and make it clearer that --ff-only is the default.

Julia Evans 85abbfc59b doc: git-pull: move <repository> and <refspec> params
From user feedback:

- it's confusing that we use both <branch> and <refspec> to refer to the
  second argument
- one user is not clear about what `refs/heads/*:refs/remotes/origin/*`
  is meant to be an example of ("is it like a path?")

The DESCRIPTION section is also doing a lot right now: it's trying to
describe both how the <repository> and <refspec> arguments work (which
is pretty complex, as seen in the DEFAULT BEHAVIOUR section)
as well as how `git pull` calls `git fetch` and merge/rebase/etc
depending on the arguments.

Handle this by moving the description of the <repository> and <refspec>
arguments to the OPTIONS section, so that we can focus on the
merge/rebase/etc behaviour in the DESCRIPTION section, and refer folks
to the later sections for details.

Use the term "upstream" instead of 'the "remote" and "merge"
configuration for the current branch' since users are more likely to
know what an "upstream" is.

Patrick Steinhardt f570bd91b3 refs/files: deprecate writing symrefs as symbolic links
The "files" backend has the ability to store symbolic refs as symbolic
links, which can be configured via "core.preferSymlinkRefs". This
feature stems back from the early days: the initial implementation of
symbolic refs used symlinks exclusively. The symref format was only
introduced in 9b143c6e15 (Teach update-ref about a symbolic ref stored
in a textfile., 2005-09-25) and made the default in 9f0bb90d16
(core.prefersymlinkrefs: use symlinks for .git/HEAD, 2006-05-02).

This is all about 20 years ago, and there are no known reasons nowadays
why one would want to use symlinks instead of symrefs. Mark the feature
for deprecation in Git 3.0.

Note that this only deprecates _writing_ symrefs as symbolic links.
Reading such symrefs is still supported for now.

Christian Couder db674095c0 doc: git-tag: stop focusing on GPG signed tags
It looks like the documentation of `git tag` is focused a bit too
much on GPG signed tags.

This starts with the "NAME" section where the command is described
with:

"Create, list, delete or verify a tag object signed with GPG"

while for example `git branch` is described with simply:

"List, create, or delete branches"

This could give the false impression that `git tag` only works with
tag objects, not with lightweight tags, and that tag objects are
always GPG signed.

In the "DESCRIPTION" section, it looks like only "GnuPG signed tag
objects" can be created by the `-s` and `-u <key-id>` options, and it
seems `gpg.program` can only specify a "custom GnuPG binary".

This goes on in the "OPTIONS" section too, especially about the `-s`
and `-u <key-id>` options.

The "CONFIGURATION" section also doesn't talk about how to configure
the command to work with X.509 and SSH signatures.

Let's rework all that to make sure users have a more accurate and
balanced view of what the command can do.

brian m. carlson 24d46f8633 docs: improve ambiguous areas of pack format documentation
It is fair to say that our pack and indexing code is quite complex.
Contributors who wish to work on this code or implementors of other
implementations would benefit from clear, unambiguous documentation
about how our data formats are structured and encoded and what data is
used in the computation of certain values.  Unfortunately, some of this
data is missing, which leads to confusion and frustration.

Let's document some of this data to help clarify things.  Specify over
what data CRC32 values are computed and also note which CRC32 algorithm
is used, since Wikipedia mentions at least four 32-bit CRC algorithms
and notes that it's possible to use different bit orderings.

In addition, note how we encode objects in the pack.  One might be led
to believe that packed objects are always stored with the "<type>
<size>\0" prefix of loose objects, but that is not the case, although
for obvious reasons this data is included in the computation of the
object ID.  Explain why this is for the curious reader.

Finally, indicate what the size field of the packed object represents.
Otherwise, a reader might think that the size of a delta is the size of
the full object or that it might contain the offset or object ID,
neither of which are the case.  Explain clearly, however, that the
values represent uncompressed sizes to avoid confusion.

The documentation for the hash function transition reflects the original

However, due to a missed patch in Git 2.29, we shipped SHA-256 support

signature and the opposite algorithm is always in a header.  Since the
documentation is inaccurate, update it to reflect the correct
information.

brian m. carlson 6947ed321d docs: update offset order for pack index v3
The current design of pack index v3 has items in two different orders:
sorted shortened object ID order and pack order.  The shortened object
IDs and the pack index offset values are in the former order and
everything else is in the latter.

This, however, poses some problems.  We have many parts of the packfile
code that expect to find out data about an object knowing only its index
in pack order.  With the current design, to find the pack offset after
having looked up the index in pack order, we must then look up the full
object ID and use that to look up the shortened object ID to find the
pack offset, which is inconvenient, inefficient, and leads to poor cache
usage.

Instead, let's change the offset values to be looked up by pack order.
This works better because once we know the pack order offset, we can
find the full object name and its location in the pack with a simple
index into their respective tables.  This makes many operations much
more efficient, especially with the functions we already have, and it
avoids the need for the revindex with pack index v3.

brian m. carlson 87264b7dde docs: update pack index v3 format
Our current pack index v3 format uses 4-byte integers to find the
trailer of the file.  This effectively means that the file cannot be
much larger than 2^32.  While this might at first seem to be okay, we
expect that each object will have at least 64 bytes worth of data, which
means that no more than about 67 million objects can be stored.

Again, this might seem fine, but unfortunately, we know of many users
who attempt to create repos with extremely large numbers of commits to
get a "high score," and we've already seen repositories with at least 55
million commits.  In the interests of gracefully handling repositories
even for these well-intentioned but ultimately misguided users, let's
change these lengths to 8 bytes.

For the checksums at the end of the file, we're producing 32-byte
SHA-256 checksums because that's what we already do with pack index v2
and SHA-256.  Truncating SHA-256 doesn't pose any actual security
problems other than those related to the reduced size, but our pack
checksum must already be 32 bytes (since SHA-256 packs have 32-byte
checksums) and it simplifies the code to use the existing hashfile logic
for these cases for the index checksum as well.

In addition, even though we may not need cryptographic security for the
index checksum, we'd like to avoid arguments from auditors and such for
organizations that may have compliance or security requirements.  Using
the simple, boring choice of the full SHA-256 hash avoids all possible
discussion related to hash truncation and removes impediments for these
organizations.

Note that we do not yet have a pack index v3 implementation in Git, so
it should be fine to change this format.  However, such an
implementation has been written for future inclusion following this
format.

When the value given to a configuration variable whose type is
pathname wants to signal such an optional file, it can be marked by
prepending ":(optional)" in front of it.  Such a setting that is
marked optional would avoid getting the command barf for a missing
file, as an optional configuration setting that names a missing

The confusion comes from a paragraph following a list item (ironically,

now that we are a top-level definition list, it is OK to do so (and in

Julia Evans 6e1688f1f4 doc: git-push: clarify "what to push"
From user feedback: 6 users says they found the "what to push"
paragraphs confusing, for many different reasons, including:

* what does "..." in <refspec>... mean?
* "consult XXX configuration" is hard to parse
* it refers to the `git-config` man page even though the config
  information for `git push` is included in this man page under
  CONFIGURATION
* the default ("push to a branch with the same name") is what they use
  99% of the time, they would have expected it to appear earlier instead
  of at the very end
* not understanding what the term "upstream" means in Git
  ("are branches tracked by some system besides their names?"")

Also, the current explanation of `push.default=simple` ("the
current branch is pushed to the corresponding upstream branch, but
as a safety measure, the push is aborted if the upstream branch
does not have the same  name as the local one.") is not accurate:
`push.default=simple` does not always require you to set a corresponding
upstream branch.

Address all of these by

* using a numbered "in order of precedence" list
* giving a more accurate explanation of how `push.default=simple` works
* giving a little bit of context around "upstream branch": it's
  something that you may have to set explicitly
* referring to the new UPSTREAM BRANCHES section

The default behaviour is still discussed pretty late but it should be
easier to skim now to get to the relevant information.

In "`git push` may fail if...",  I'm intentionally being vague about
what exactly `git push` does, because (as discussed on the mailing list)
the behaviour of `push.default=simple` is very confusing, perhaps broken,
and certainly not worth trying to explain in an introductory context.
`push.default.simple` sometimes requires you to set an upstream and
sometimes doesn't and the exact conditions under which it does/doesn't
are hard to describe.

Julia Evans 428d7a0d89 doc: add an UPSTREAM BRANCHES section to pull/push/fetch
From user feedback: one user mentioned that they don't know what the
term "upstream branch" means. As far as I can tell, the most complete
description is under the `--track` option in `git branch`. Upstreams
are an important concept in Git and the `git branch` man page is not an
obvious place for that information to live.

There's also a very terse description of "upstream branch" in the
glossary that's missing a lot of key information, like the fact that the
upstream is used by `git status` and `git pull`, as well as a
description in `git-config` in `branch.<name>.remote` which doesn't
explain the relationship to `git status` either.

Since the `git pull`, `git push`, and `git fetch` man pages already
include sections on REMOTES and the syntax for URLs, add a section on
UPSTREAM BRANCHES to `urls-remotes.adoc`.

In the new UPSTREAM BRANCHES section, cover the various ways that
upstreams branches are automatically set in Git, since users may
mistakenly think that their branch does not have an upstream branch if
they didn't explicitly set one.

A terminology note: Git uses two terms for this concept:

- "tracking" as in "the tracking information for the 'foo' branch"
  or the `--track` option to `git branch`
- "upstream" or "upstream branch", as in `git push --set-upstream`.
  This term is also used in the `git rebase` man page to refer to the
  first argument to `git rebase`, as well as in `git pull` to refer to
  the branch which is going to be merged into the current branch ("merge
  the upstream branch into the current branch")

Use "upstream branch" as a heading for this concept even though the term
"upstream branch" is not always used strictly in the sense of "the
tracking information for the current branch". "Upstream" is used much
more often than "tracking" in the Git docs to refer to this concept and
the goal is to help users understand the docs.

Many users also commented that receive hooks do not seem like the most

should not be the second sentence in the man page.

Use more familiar language to make it more accessible to users who do
not know what a "ref" is and move the "hooks" comment to the end.

René Scharfe 171c1688cc add-patch: let options y, n, j, and e roll over to next undecided
The options y, n, and e mark the current hunk as decided.  If there's
another undecided hunk towards the bottom of the hunk array they go
there.  If there isn't, but there is another undecided hunk towards the
top then they go to the very first hunk, no matter if it has already
been decided on.

The option j does basically the same move.  Technically it is not
allowed if there's no undecided hunk towards the bottom, but the
variable "permitted" is never reset, so this permission is retained
from the very first hunk.  That may a bug, but this behavior is at
least consistent with y, n, and e and arguably more useful than
refusing to move.

Improve the roll-over behavior of these four options by moving to the
first undecided hunk instead of hunk 1, consistent with what they do
when not rolling over.

Also adjust the error message for j, as it will only be shown if
there's no other undecided hunk in either direction.

The variable "permitted" is not reset after moving to a different hunk,
so it only accumulates permission and doesn't necessarily reflect those

option J, which can be used at the last hunk to roll over to the first
hunk.  Make this particular behavior official.

Commit bcf7edee09 ("meson: generate articles", 2024-12-27) added the
generation of the 'howto' and 'technical' documents to the meson build.
At this time those documents had a '*.txt' file extension, but they were
renamed with an '*.adoc' extension by commit 1f010d6bdf ("doc: use .adoc
extension for AsciiDoc files", 2025-01-20), for the most part. For the
meson build, commit 87eccc3a81 ("meson: fix building technical and howto
docs", 2025-03-02) fixed the meson.build files, which had not been
updated when the files were renamed.

However, the 'Documentation/Makefile' has not been updated to include
all of the recently added technical documents. In particular, the
following are built by meson, but not by the Makefile:

    commit-graph.adoc
    directory-rename-detection.adoc
    packfile-uri.adoc
    remembering-renames.adoc
    repository-version.adoc
    rerere.adoc
    sparse-checkout.adoc
    sparse-index.adoc

In order to ensure that both build systems format the same technical
documents, add the above documents to the TECH_DOCS variable in the
Documentation/Makefile.

Patrick Steinhardt 8f5daaff92 BreakingChanges: announce Rust becoming mandatory
Over the last couple of years the appetite for bringing Rust into the
codebase has grown significantly across the developer base. Introducing
Rust is a major change though and has ramifications for the whole
ecosystem:

  - Some platforms have a Rust toolchain available, but have not yet
    integrated it into their build infrastructure.

  - Some platforms don't have any support for Rust at all.

  - Some platforms may have to figure out how to fit Rust into their
    bootstrapping sequence.

Due to this, and given that Git is a critical piece of infrastructure
for the whole industry, we cannot just introduce such a heavyweight
dependency without doing our due diligence.

Instead, preceding commits have introduced a test balloon into our build
infrastructure that convert one tiny subsystem to use Rust. For now,
using Rust to build that subsystem is entirely optional -- if no Rust
support is available, we continue to use the C implementation. This test
balloon has the intention to give distributions time and let them ease
into our adoption of Rust.

Having multiple implementations of the same subsystem is not sustainable
though, and the plan is to eventually be able to use Rust freely all
across our codebase. As such, there is the intent to make Rust become a
mandatory part of our build process.

Add an announcement to our breaking changes that Rust will become
mandatory in Git 3.0. A (very careful and non-binding) estimate might be
that this major release might be released in the second half of next
year, which should give distributors enough time to prepare for the
change.

All the final paragraphs on these three options are rendered as
literal blocks. The intent was surely to keep each of them wed to their
respective description list items. But the attempt at maintaining the
indentation level of the block causes each them to be interpreted as a
code block, since code blocks can be represented using indentation.

We need to use list continuation (+) in order to keep them wed to
their blocks.

There is also an unordered list which sandwiches two paragraphs on an
option. We don’t need to do anything about that since it attaches to the
description list item without list continuation (i.e. it is already
correct). But for consistency let’s use list continuation and an open

With stash.index=true, git-stash(1) command now tries to reinstate the
index by default in the "apply" and "pop" modes. Not doing so creates a
common trap [1], [2]: "git stash apply" is not the reverse of "git stash
push" because carefully staged indices are lost and have to be manually
recreated. OTOH, this mode is not always desirable and may create more
conflicts when applying stashes. As usual, "--no-index" will disable
this behavior if you set "stash.index".

Meet Soni ecc70a48a5 builtin/refs: add optimize subcommand
As part of the ongoing effort to consolidate reference handling,
introduce a new `optimize` subcommand. This command provides the same
functionality and exit-code behavior as `git pack-refs`, serving as its
modern replacement.

Implement `cmd_refs_optimize` by having it call the `pack_refs_core()`
helper function. This helper was factored out of the original
`cmd_pack_refs` in a preceding commit, allowing both commands to share
the same core logic as independent peers.

Add documentation for the new command. The man page leverages the shared
options file, created in a previous commit, by using the AsciiDoc
`include::` macro to ensure consistency with git-pack-refs(1).

Kristoffer Haugsbakk 5a31252702 whatchanged: hint about git-log(1) and aliasing
There have been quite a few `--i-still-use-this` user reports since Git
2.51.0 was released.[1][2]  And it doesn’t seem like they are reading
the man page about the git-log(1) equivalent.

Tell them what options to plug into git-log(1), either as a replacement
command or as an alias.[3]  That template produces almost the same
output[4] and is arguably a plug-in replacement.  Concretely, add
an optional `hint` argument so that we can use it right after the
initial error line.

Also mention the same concrete options in the documentation while we’re
at it.

Kristoffer Haugsbakk bf68b11699 git: allow alias-shadowing deprecated builtins
git-whatchanged(1) is deprecated and you need to pass
`--i-still-use-this` in order to force it to work as before.
There are two affected users, or usages:

1. people who use the command in scripts; and
2. people who are used to using it interactively.

For (1) the replacement is straightforward.[1]  But people in (2) might
like the name or be really used to typing it.[3]

An obvious first thought is to suggest aliasing `whatchanged` to the
git-log(1) equivalent.[1]  But this doesn’t work and is awkward since you
cannot shadow builtins via aliases.

Now you are left in an uncomfortable limbo; your alias won’t work until
the command is removed for good.

Let’s lift this limitation by allowing *deprecated* builtins to be
shadowed by aliases.

The only observed demand for aliasing has been for git-whatchanged(1),
not for git-pack-redundant(1).  But let’s be consistent and treat all
deprecated commands the same.

[1]:

        git log --raw --no-merges

     With a minor caveat: you get different outputs if you happen to
     have empty commits (no changes)[2]

Kristoffer Haugsbakk 5f31632ed7 git: add `deprecated` category to --list-cmds
With 145 builtin commands (according to `git --list-cmds=builtins`),
users are probably not keeping on top of which ones (if any) are
deprecated.

Let’s expand the experimental `--list-cmds`[1] to allow users and
programs to query for this information.  We will also use this in an
upcoming commit to implement `is_deprecated_command`.

[1]: Using something which is experimental to query for deprecations is
    perhaps not the most ideal approach, but it is simple to implement
    and better than having to scan the documentation

Christian Couder eaaddf5791 fast-import: add '--signed-commits=<mode>' option
A '--signed-commits=<mode>' option is already available when using
`git fast-export` to decide what should be done at export time about
commit signatures. At import time though, there is no option, or
other way, in `git fast-import` to decide about commit signatures.

To remediate that, let's add a '--signed-commits=<mode>' option to
`git fast-import` too.

For now the supported <mode>s are the same as those supported by
`git fast-export`.

The code responsible for consuming a signature is refactored into
the import_one_signature() and discard_one_signature() functions,
which makes it easier to follow the logic and add new modes in the
future.

In the 'strip' and 'warn-strip' modes, we deliberately use
discard_one_signature() to discard the signature without parsing it.
This ensures that even malformed signatures, which would cause the
parser to fail, can be successfully stripped from a commit.

Derrick Stolee 5b5a7f5ebd sparse-checkout: add --verbose option to 'clean'
The 'git sparse-checkout clean' subcommand is focused on directories,
deleting any tracked sparse directories to clean up the worktree and
make the sparse index feature work optimally.

However, this directory-focused approach can leave users wondering why
those directories exist at all. In my experience, these files are left
over due to ignore or exclude patterns, Windows file handles, or
possibly merge conflict resolutions.

Add a new '--verbose' option for users to see all the files that are
being deleted (with '--force') or would be deleted (with '--dry-run').

Based on usage, users may request further context on this list of files for
states such as tracked/untracked, unstaged/staged/conflicted, etc.

Derrick Stolee a8077c1913 sparse-checkout: match some 'clean' behavior
The 'git sparse-checkout clean' subcommand is somewhat similar to 'git
clean' in that it will delete files that should not be in the worktree.
The big difference is that it focuses on the directories that should not
be in the worktree due to cone-mode sparse-checkout. It also does not
discriminate in the kinds of files and focuses on deleting entire
directories.

However, there are some restrictions that would be good to bring over
from 'git clean', specifically how it refuses to do anything without the
'-f'/'--force' or '-n'/'--dry-run' arguments. The 'clean.requireForce'
config can be set to 'false' to imply '--force'.

Add this behavior to avoid accidental deletion of files that cannot be
recovered from Git.

Derrick Stolee 2520efd3bc sparse-checkout: add basics of 'clean' command
When users change their sparse-checkout definitions to add new
directories and remove old ones, there may be a few reasons why
directories no longer in scope remain (ignored or excluded files still
exist, Windows handles are still open, etc.). When these files still
exist, the sparse index feature notices that a tracked, but sparse,
directory still exists on disk and thus the index expands. This causes a
performance hit _and_ the advice printed isn't very helpful. Using 'git
clean' isn't enough (generally '-dfx' may be needed) but also this may
not be sufficient.

Add a new subcommand to 'git sparse-checkout' that removes these
tracked-but-sparse directories.

The implementation details provide a clear definition of what is happening,
but it is difficult to describe this without including the internal
implementation details. The core operation converts the index to a sparse
index (in memory if not already on disk) and then deletes any directories in
the worktree that correspond with a sparse directory entry in that sparse
index.

In the most common case, this means that a file will be removed if it is
contained within a directory that is both tracked and outside of the
sparse-checkout definition. However, there can be exceptions depending on
the current state of the index:

 * If the worktree has a modification to a tracked, sparse file, then that
   file's parent directories will be expanded instead of represented as
   sparse directories. Siblings of those parent directories may be
   considered sparse.

 * If the user staged a sparse file with "git add --sparse", then that file
   loses the SKIP_WORKTREE bit until the sparse-checkout is reapplied. Until
   then, that file's parent directories are not represented as sparse
   directory entries and thus will not be removed. Siblings of those parent
   directories may be considered sparse. (There may be other reasons why
   the SKIP_WORKTREE bit was removed for a file and this impact on the
   sparse directories will apply to those as well.)

 * If the user has a merge conflict outside of the sparse-checkout
   definition, then those conflict entries prevent the parent directories
   from being represented as sparse directory entries and thus are not
   removed.

 * The cases above present reasons why certain _file conditions_ will impact
   which _directories_ are considered sparse. The list of tracked
   directories that are outside of the sparse-checkout definition but not
   represented as a sparse directory further reduces the list of files that
   will be removed.

For these complicated reasons, the documentation details a potential list of
files that will be "considered for removal" instead of defining the list
concretely. The special cases can be handled by resolving conflicts,
committing staged changes, and running 'git sparse-checkout reapply' to
update the SKIP_WORKTREE bits as expected by the sparse-checkout definition.

It is important to make clear that this operation will remove ignored and
excluded files which would normally be ignored even by 'git clean -f' unless
the '-x' or '-X' option is provided. This is the most extreme method for
doing this, but it works when the sparse-checkout is in cone mode and is
expected to rescope based on directories, not files.

The current implementation always deletes these sparse directories
without warning. This is unacceptable for a released version, but those
features will be added in changes coming immediately after this one.

Note that this will not remove an untracked directory (or any of its
contents) if its parent is a tracked directory within the sparse-checkout
definition. This is required to prevent removing data created by tools that
perform caching operations for editors or build tools.

Thus, 'git sparse-checkout clean' is both more aggressive and more careful
than 'git clean -fx':

 * It is more aggressive because it will remove _tracked_ files within the
   sparse directories.

 * It is less aggressive because it will leave _untracked_ files that are
   not contained in sparse directories.

These special cases will be handled more explicitly in a future change that
expands tests for the 'git sparse-checkout clean' command. We handle some of
the modified, staged, and committed states including some impact on 'git
status' after cleaning.
