t: add test for git refs optimize subcommand
Add a test script, `t/t1463-refs-optimize.sh`, for the new `git refs
optimize` command.
This script acts as a simple driver, leveraging the shared test library
created in the preceding commit. It works by overriding the
`$pack_refs` variable to "refs optimize" and then sourcing the
shared library (`t/pack-refs-tests.sh`).
This approach ensures that `git refs optimize` is tested against the
entire comprehensive test suite of `git pack-refs`, verifying
that it acts as a compatible drop-in replacement.

t0601: refactor tests to be shareable
In preparation for adding tests for the new `git refs optimize` command,
refactor the existing t0601 test suite to make its logic shareable.
Move the core test logic from `t0601-reffiles-pack-refs.sh` into a new
`pack-refs-tests.sh` file. Inside this new script, replace hardcoded
calls to "pack-refs" with the `$pack_refs` variable.
The original `t0601-reffiles-pack-refs.sh` script now becomes a simple
"driver". It is responsible for setting the default value of the
variable and then sourcing the test library.
This new structure follows the established pattern used for sharing
tests between `git-for-each-ref` and `git-refs list` and prepares the
test suite for the `refs optimize` tests to be added in a subsequent

The `git pack-refs` command behaves generically, triggering a pack for

To create a cleaner, more generic interface, refactor `git pack-refs` to

- keyvalue, where the retrieved data is printed one per line, using =
for delimiting the key and the value. This is the default format,
targeted for end users.
- nul, where the retrieved data is separated by NUL characters, using
the newline character for delimiting the key and the value. This
format is targeted for being read by machines.

Currently, `git rev-parse` covers a wide range of functionality not
directly related to parsing revisions, as its name suggests. Over time,
many features like parsing datestrings, options, paths, and others
were added to it because there wasn't a more appropriate command
to place them.
Create a new Git command called `repo`. `git repo` will be the main
command for obtaining the information about a repository (such as
metadata and metrics).
Also declare a subcommand for `repo` called `info`. `git repo info`
will bring the functionality of retrieving repository-related
information currently returned by `rev-parse`.

commit-graph: stop passing in redundant repository
Many of the commit-graph related functions take in both a repository and
the object database source (directly or via `struct commit_graph`) for
which we are supposed to load such a commit-graph. In the best case this
information is simply redundant as the source already contains a
reference to its owning object database, which in turn has a reference
to its repository. In the worst case this information could even
mismatch when passing in a source that doesn't belong to the same
repository.
Refactor the code so that we only pass in the object database source in
those cases.
There is one exception though, namely `load_commit_graph_chain_fd_st()`,
which is responsible for loading a commit-graph chain. It is expected
that parts of the commit-graph chain aren't located in the same object
source as the chain file itself, but in a different one. Consequently,
this function doesn't work on the source level but on the database level
instead.

Refactor `parse_commit_graph()` so that it takes a repository instead of

algorithm instead. On the other hand it also allows us to move the call
of `prepare_repo_settings()` into the function itself.
Note that there's one small catch, as the commit-graph fuzzer calls this
function directly without having a fully functional repository at hand.
And while the fuzzer already initializes `the_repository` with relevant
info, the call to `prepare_repo_settings()` would fail because we don't
have a fully-initialized repository.
Work around the issue by also settings `settings.initialized` to pretend
that we've already read the settings.

docs: remove stray bracket from git-clone synopsis
The synopsis section has an extra closing bracket, like this:
[--filter=<filter>] [--also-filter-submodules]]
The extra one is not the one at the end of this line; it is the one
after "...=<filter>".
The "--also-filter-submodules" option was added by f05da2b4 (clone,
submodule: pass partial clone filters to submodules, 2022-02-04).
Because it makes sense only when used with the "--filter=<filter>"
option, these two options are enclosed in a pair of brackets. The
extra one was added by 76880f05 (doc: git-clone: apply new
documentation formatting guidelines, 2024-03-29) by mistake.
Remove the extra and incorrect closing bracket, so that the line
reads:

doc: check well-formedness of delimited sections
Having an empty line before each delimited sections is not required by
asciidoc, but it is a safety measure that prevents generating malformed
asciidoc when generating translated documentation.
When a delimited section appears just after a paragraph, the asciidoc
processor checks that the length of the delimited section header is
different from the length of the paragraph. If it is not, the asciidoc
processor will generate a title. In the original English documentation, this
is not a problem because the authors always check the output of the asciidoc
processor and fix the length of the delimited section header if it turns out
to be the same as the paragraph length. However, this is not the case for
translations, where the authors have no way to check the length of the
delimited section header or the output of the asciidoc processor. This can
lead to a section title that is not intended.
Indeed, this test also checks that titles are correctly formed, that is,
the length of the underline is equal to the length of the title (otherwise
it would not be a title but a section header).
Finally, this test checks that the delimited section are terminated within
the same file.

That is, for a file "foo.txt", `git diff --no-prefix` will emit:
+++ foo.txt
but for "foo bar.txt" it will emit:
+++ foo bar.txt\t
This in turn leads `git-jump` to produce a quickfix format like this:
foo bar.txt\t:1:1:contents
Because no "foo bar.txt\t" file actually exists on disk, opening it in
Vim will just land the user in an empty buffer.
This commit takes the simple approach of unconditionally stripping any
trailing tab. Consider the following three examples:
1. For file "foo", Git will emit "foo".
2. For file "foo bar", Git will emit "foo bar\t".
3. For file "foo\t", Git will emit "\"foo\t\"".
4. For file "foo bar\t", Git will emit "\"foo bar\t\"".
Before this commit, `git-jump` correctly handled only case "1".
After this commit, `git-jump` correctly handles cases "1" and "2". In
reality, these are the only cases people are going to run into with any
regularity, and the other two are rare edge cases, which probably aren't
worth the effort to support unless somebody actually complains about
them.

bloom: enable bloom filter with wildcard pathspec in revision traversal
When traversing commits, a pathspec item can be used to limit the
traversal to commits that modify the specified paths. And the
commit-graph includes a Bloom filter to exclude commits that definitely
did not modify a given pathspec item. During commit traversal, the
Bloom filter can significantly improve performance. However, it is
disabled if the specified pathspec item contains wildcard characters
or magic signatures.
For performance reason, enable Bloom filter even if a pathspec item
contains wildcard characters by filtering only the non-wildcard part of
the pathspec item.
The function of pathspec magic signature is generally to narrow down
the path specified by the pathspecs. So, enable Bloom filter when
the magic signature is "top", "glob", "attr", "--depth" or "literal".
"exclude" is used to select paths other than the specified path, rather
than serving as a filtering function, so it cannot be used together with
the Bloom filter. Since Bloom filter is not case insensitive even in
case insensitive system (e.g. MacOS), it cannot be used together with
"icase" magic.
With this optimization, we get some improvements for pathspecs with
wildcards or magic signatures. First, in the Git repository we see these
modest results:
git log -100 -- "t/*"

Time (mean ± σ): 20.4 ms ± 0.6 ms

better results:

diff: --no-index should ignore the worktree
The act of giving "--no-index" tells Git to pretend that the current
directory is not under control of any Git index or repository, so
even when you happen to be in a Git controlled working tree, where
in that working tree should not matter.
But the start-up sequence tries to discover the top of the working
tree and chdir(2)'s there, even before Git passes control to the
subcommand being run. When diff_no_index() starts running, it
starts at a wrong (from the end-user's point of view who thinks
"git diff --no-index" is merely a better version of GNU diff)
directory, and the original directory the user started the command
is at "prefix".
Because the paths given from argv[] have already been adjusted to
account for this path shuffling by prepending the prefix, and
showing the resulting path by stripping the prefix, the effect of
these nonsense operations (nonsense in the context of "--no-index",
that is) is usually not observable.
Except for special cases like "-", where it is not preprocessed by
prepending the prefix.
Instead of papering over by adding more special cases only to cater
to the no-index codepath in the generic code, drive the diff
machinery more faithfully to what is going on. If the user started
"git diff --no-index" in directory X/Y/Z in a working tree
controlled by Git, and the start up sequence of Git chdir(2)'ed up
to directory X and left Y/Z in the prefix, revert the effect of the
start up sequence by chdir'ing back to Y/Z and emptying the prefix.

t6137-*.sh: fix test failure on cygwin
Commit 6fd1106aa4 ("t3700: Skip a test with backslashes in pathspec",
2009-03-13) introduced the BSLASHPSPEC prerequisite. This prerequisite
allows tests to check for systems that can use backslashes in pathspecs
(e.g. to escape glob special characters). On windows (and cygwin), this
does not work because backslashes are used as directory separators, and
git eagerly converts them to forward slashes.
This test file uses the FUNNYNAMES prerequisite to skip this test file
on windows, despite not really being appropriate for this test, which
does not hold on cygwin. The FUNNYNAMES prerequisite is set when the
system can create files with embedded quotes ("), tabs or newlines in
the name. Since cygwin can satisfy FUNNYNAMES, but not BSLASHPSPEC, this
leads to test failures on cygwin.
In order to skip these tests on cygwin, replace the FUNNYNAMES prerequisite
with BSLASHPSPEC, so that this test file is skipped on both windows and
cygwin. While here, fix a few test titles as well.

When "git push <remote> <src>:<dst>" does not spell out the

The type is determined by calling odb_read_object_info() and

programming error with BUG() when this function said that there
is no such object, which happens when the object name is given
as a full hexadecimal (if the object name is given as a partial
hexadecimal or an non-existing ref, the function would have died
without returning, so this BUG() wouldn't have triggered). This
is wrong. It is an ordinary end-user mistake to give an object
name that does not exist and treated as such.
An example of the error message produced is as follows:
error: The destination you provided is not a full refname (i.e.,
starting with "refs/"). We tried to guess what you meant by:
- Looking for a ref that matches 'branch' on the remote side.
