alloc_nr, ALLOC_GROW, and ALLOC_GROW_BY are commonly used macros for
dynamic array allocation. Moving these macros to git-compat-util.h with
the other alloc macros focuses alloc.[ch] to allocation for Git objects
and additionally allows us to remove inclusions to alloc.h from files
that solely used the above macros.

This table was originally introduced to solely be used with kwset
machinery (0f871cf56e), so it would make sense for it to belong in
kwset.[ch] rather than ctype.c and git-compat-util.h. It is only used in
diffcore-pickaxe.c, which already includes kwset.h so no other headers
have to be modified.

In 4dc16e2cb0 (gc: introduce `gc.recentObjectsHook`, 2023-06-07), we
added tests to ensure that prune-able (i.e. unreachable and with mtime
older than the cutoff) objects which are marked as recent via the new
`gc.recentObjectsHook` configuration are unpacked as loose with
`--unpack-unreachable`.
In that test, we also ensure that objects which are reachable from other
unreachable objects which were *not* pruned are kept as well, regardless
of their mtimes. For this, we use an annotated tag pointing at a blob
($obj2) which would otherwise be pruned.
But after pruning, that object is kept around for two reasons. One, the
tag object's mtime wasn't adjusted to be beyond the 1-hour cutoff, so it
would be kept as due to its recency regardless. The other reason is
because the tag itself is reachable.
Use mktag to write the tag object directly without pointing a reference
at it, and adjust the mtime of the tag object to be older than the
cutoff to ensure that our `gc.recentObjectsHook` configuration is
working as intended.

When an external merge driver dies with a signal, we should not
expect that the result left on the filesystem is in any useful
state. However, because the current code uses the return value from
run_command() and declares any positive value as a sign that the
driver successfully left conflicts in the result, and because the
return value from run_command() for a subprocess that died upon a
signal is positive, we end up treating whatever garbage left on the
filesystem as the result the merge driver wanted to leave us.
run_command() returns larger than 128 (WTERMSIG(status) + 128, to be
exact) when it notices that the subprocess died with a signal, so
detect such a case and return LL_MERGE_ERROR from ll_ext_merge().

This creates a new fsmonitor-ll.h with most of the functions from
fsmonitor.h, though it leaves three inline functions where they were.
Two-thirds of the files that previously included fsmonitor.h did not
need those three inline functions or the six extra includes those inline
functions required, so this allows them to only include the lower level
header.

oidhash() was used by both hashmap and khash, which makes sense.
However, the location of this function in hashmap.[ch] meant that
khash.h had to depend upon hashmap.h, making people unfamiliar with
khash think that it was built upon hashmap. (Or at least, I personally
was confused for a while about this in the past.)
Move this function to hash-ll, so that khash.h can stop depending upon
hashmap.h.
This has another benefit as well: it allows us to remove hashmap.h's
dependency on hash-ll.h. While some callers of hashmap.h were making
use of oidhash, most were not, so this change provides another way to
reduce the number of includes.

khash.h lets you instantiate custom hash types that map between two
types. These are defined as a struct, as you might expect, and khash
typedef's that to kh_foo_t. But it declares the struct anonymously,
which doesn't give a name to the struct type itself; there is no
"struct kh_foo". This has two small downsides:
- when using khash, we declare "kh_foo_t *the_foo". This is
unlike our usual naming style, which is "struct kh_foo *the_foo".
- you can't forward-declare a typedef of an unnamed struct type in
C. So we might do something like this in a header file:
struct kh_foo;
struct bar {
struct kh_foo *the_foo;
};
to avoid having to include the header that defines the real
kh_foo. But that doesn't work with the typedef'd name. Without the
"struct" keyword, the compiler doesn't know we mean that kh_foo is
a type.
So let's always give khash structs the name that matches our
conventions ("struct kh_foo" to match "kh_foo_t"). We'll keep doing
the typedef to retain compatibility with existing callers.

A long term (but rather minor) pet-peeve of mine was the name
ll-merge.[ch]. I thought it made it harder to realize what stuff was
related to merging when I was working on the merge machinery and trying
to improve it.
Further, back in d1cbe1e6d8a ("hash-ll.h: split out of hash.h to remove
dependency on repository.h", 2023-04-22), we have split the portions of
hash.h that do not depend upon repository.h into a "hash-ll.h" (due to
the recommendation to use "ll" for "low-level" in its name[1], but which
I used as a suffix precisely because of my distaste for "ll-merge").
When we discussed adding additional "*-ll.h" files, a request was made
that we use "ll" consistently as either a prefix or a suffix. Since it
is already in use as both a prefix and a suffix, the only way to do so
is to rename some files.
Besides my distaste for the ll-merge.[ch] name, let me also note that
the files
ll-fsmonitor.h, ll-hash.h, ll-merge.h, ll-object-store.h, ll-read-cache.h
would have essentially nothing to do with each other and make no sense
to group. But giving them the common "ll-" prefix would group them. Using
"-ll" as a suffix thus seems just much more logical to me. Rename
ll-merge.[ch] to merge-ll.[ch] to achieve this consistency, and to
ensure we get a more logical grouping of files.

(Makefile: add USE_WILDMATCH to use wildmatch as fnmatch, 2013-01-01) as

Note that compat/fsmonitor/fsm-path-utils-darwin.c previously got
away with violating the rule that all files must start with an include
of git-compat-util.h (or a short-list of alternate headers that happen

The function add_files_to_cache() is used by all three of builtin/{add,
checkout, commit}.c. That suggests this is common library code, and
should be moved somewhere else, like read-cache.c. However, the
function and its helpers made use of two global variables that made
straight code movement difficult:
* the_index
* include_sparse
The latter was perhaps more problematic since it was only accessible in
builtin/add.c but was still affecting builtin/checkout.c and
builtin/commit.c without this fact being very clear from the code. I'm
not sure if the other two callers would want to add a `--sparse` flag
similar to add.c to get non-default behavior, but exposing this
dependence will help if we ever decide we do want to add such a flag.
Modify add_files_to_cache() and its helpers to accept the necessary
arguments instead of relying on globals.

This commit was prompted by a desire to move the functions which
builtin/init-db.c and builtin/clone.c share out of the former file and
into setup.c. One issue that made it difficult was the
init_is_bare_repository global variable.
init_is_bare_repository's sole use in life it to cache a value in
init_db(), and then be used in create_default_files(). This is a bit
odd since init_db() directly calls create_default_files(), and is the
only caller of that function. Convert the global to a simple function
parameter instead.
(Of course, this doesn't fix the fact that this value is then ignored by
create_default_files(), as noted in a big TODO comment in that function,
but it at least includes no behavioral change other than getting rid of
a very questionable global variable.)

The comments in create_default_files() talks about reading config from
the config file in the specified `--templates` directory, which leads to
the question of whether core.bare could be set in such a config file and
thus whether the code is doing the right thing. It turns out, that it
doesn't; it unconditionally ignores core.bare in the config file in any
--templates directory. It is not clear to me that fixing it can be done
within this function; it seems to occur too late:
* create_default_files() is called by init_db()
* init_db() is called by both builtin/{clone.c,init-db.c}
* both callers of init_db() call set_git_work_tree() before init_db()
and in order to actual affect whether a repository is bear, we'd need to
somewhere reset these values, not just the is_bare_repository_cfg
setting.
I do not want to open this can of worms at this time; I'm trying to
clean up some headers, for which I need to move some functions, for
which I need to clean up some globals, and that's far enough down the
rabbit hole. So, simply document the issue with a careful TODO comment
and a few testcases.

The value of config.worktree is per-repository, but has been kept
in a singleton global variable per process. This has been OK as
most Git operations interacted with a single repository at a time,

When installing a packfile, we place the .pack file before the .idx
file. The intention is that Git scans for .idx files in the pack
directory and then loads the .pack files from that list.
However, when we delete packfiles, we do not do this in the reverse
order as we should. The unlink_pack_path() method deletes the .pack
followed by the .idx.
This creates a window where the process could be interrupted between
the .pack deletion and the .idx deletion, leaving the repository in a
state that looks strange, but isn't actually too problematic if we
assume the pack was safe to delete. The .idx without a .pack will cause
some overhead, but will not interrupt other Git processes.
This ordering was introduced into the 'git repack' builtin by
a1bbc6c0176 (repack: rewrite the shell script in C, 2013-09-15), though
we must be careful to track history through the code move in 8434e85d5f9
(repack: refactor pack deletion for future use, 2019-06-10) to see that.
This became more important after 73320e49add (builtin/repack.c: only
collect fully-formed packs, 2023-06-07) changed how 'git repack' scanned
for packfiles for use in the cruft pack process. It previously looked
for .pack files, but that was problematic due to the order that packs
are installed: repacks between the creation of a .pack and the creation
of its .idx would result in hard failures.
There is an independent proposal about what to do in the case of a .idx
without a .pack during this 'git repack' scenario, but this change is
focused on deleting .pack files more safely.
Modify the order to delete the .idx before the .pack. The rest of the
modifiers on the .pack should still come after the .pack so we know all
of the presumed properties of the packfile as long as it exists in the
filesystem, in case we wish to reinstate it by re-indexing the .pack
file.

When redacting auth tokens in trace output from curl, we look for http/2
headers of the form "h2h3 [header: value]". This comes from b637a41ebe
(http: redact curl h2h3 headers in info, 2022-11-11).
But the "h2h3" prefix changed to just "h2" in curl's fc2f1e547 (http2:
support HTTP/2 to forward proxies, non-tunneling, 2023-04-14). That's in
released version curl 8.1.0; linking against that version means we'll
fail to correctly redact the trace. Our t5559.17 notices and fails.
We can fix this by matching either prefix, which should handle both old
and new versions.

In 98e7ab6d42 (for-each-ref: delay parsing of --sort=<atom> options,
2021-10-20) a new string_list was introduced to accumulate any
"branch.sort" setting.
That string_list is cleared in ref_sorting_options(), which is only
called when processing the "--list" sub-command. Therefore, with other
sub-command, while having any sort option set, a leak is produced, e.g.:
$ git config branch.sort invalid_sort_option
$ git branch --edit-description

We don't have a common clean-up section in cmd_branch(). To avoid

To handle "--abbrev-ref" we use shorten_unambiguous_ref(). This
function takes a refname and returns a shortened refname, which is a
newly allocated string that needs to be freed.
Unfortunately, the refname variable is reused to receive the shortened
one. Therefore, we lose the original refname, which needs to be freed
as well, producing a leak.
This leak can be reviewed with:
$ for a in {1..10}; do git branch foo_${a}; done
$ git rev-parse --abbrev-ref refs/heads/foo_{1..10}
Direct leak of 171 byte(s) in 10 object(s) allocated from:

When git-commit sees any "--trailer" options, it passes the
COMMIT_EDITMSG file through git-interpret-trailers. But it does so
without passing --no-divider, which means that interpret-trailers will
look for a "---" divider to signal the end of the commit message.
That behavior doesn't make any sense in this context; we know we have a
complete and solitary commit message, not something we have to further
parse. And as a result, we'll do the wrong thing if the commit message
contains a "---" marker (which otherwise is not syntactically
significant), inserting any new trailers at the wrong spot.
We can fix this by passing --no-divider. This is the exact situation for
which it was added in 1688c9a489 (interpret-trailers: allow suppressing
"---" divider, 2018-08-22). As noted in the message for that commit, it
just adds the mechanism, and further patches were needed to trigger it
from various callers. We did that back then in a few spots, like
ffce7f590f (sequencer: ignore "---" divider when parsing trailers,
2018-08-22), but obviously missed this one.

discover_git_directory() started modifying the_repository in ebaf3bcf1ae
(repository: move global r_f_p_c to repo struct, 2021-06-17), when, in
the repository setup process, we started copying members from the
"struct repository_format" we're inspecting to the appropriate "struct
repository". However, discover_git_directory() isn't actually used in
the setup process (its only caller in the Git binary is
read_early_config()), so it shouldn't be doing this setup at all!
As explained by 16ac8b8db6 (setup: introduce the
discover_git_directory() function, 2017-03-13) and the comment on its
declaration, discover_git_directory() is intended to be an entrypoint
into setup.c machinery that allows the Git directory to be discovered
without side effects, e.g. so that read_early_config() can read
".git/config" before the_repository has been set up.
Fortunately, we didn't start to rely on this unintended behavior between
then and now, so we let's just remove it. It isn't harming anyone, but
it's confusing.

`credential reject` sends the erase action to each helper, but the
exact behaviour of erase isn't specified in documentation or tests.
Some helpers (such as credential-store and credential-libsecret) delete
all matching credentials, others (such as credential-cache) delete at
most one matching credential.
Test that helpers erase all matching credentials. This behaviour is
easiest to reason about. Users expect that `echo
"url=https://example.com" | git credential reject` or `echo
"url=https://example.com\nusername=tim" | git credential reject` erase
all matching credentials.

The command can take inputs that are either just a commit message, or
an email-like output such as git-format-patch which includes a commit
message, "---" divider, and patch part. The existing explanation blends
these two inputs together in the first sentence
This command reads some patches or commit messages
which then necessitates using the "commit message part" phrasing (as
opposed to just "commit message") because the input is ambiguous per the
above definition.
This change separates the two input types and explains them separately,
and so there is no longer a need to use the "commit message part"
phrase.

When `diff.ignoreSubmodules = all` is set and submodule commits are
manually staged (e.g. via `git-update-index`), `git-commit` should
record the commit with updated submodules.
`index_differs_from` is called from `prepare_to_commit` with flags set to
`override_submodule_config = 1`. `index_differs_from` then merges the
default diff flags and passed flags.
When `diff.ignoreSubmodules` is set to "all", `flags` ends up having
both `override_submodule_config` and `ignore_submodules` set to 1. This
results in `git-commit` ignoring staged commits.
This patch restores original `flags.ignore_submodule` if
`flags.override_submodule_config` is set.

The commit d3115660b4 (branch: add flags and config to inherit tracking,
2021-12-20) replaced in "struct tracking", the member "char *src" by a
new "struct string_list *srcs".
This caused a modification in find_tracked_branch(). The string
returned by remote_find_tracking(), previously assigned to "src", is now
added to the string_list "srcs".
That string_list is initialized with STRING_LIST_INIT_DUP, which means
that what is added is not the given string, but a duplicate. Therefore,
the string returned by remote_find_tracking() is leaked.
The leak can be reviewed with:
$ git branch foo
$ git remote add local .
$ git fetch local
$ git branch --track bar local/foo
Direct leak of 24 byte(s) in 1 object(s) allocated from:
... in xrealloc wrapper.c

... in create_branch branch.c
... in cmd_branch builtin/branch.c
... in run_builtin git.c
Let's fix the leak, using the "_nodup" API to add to the string_list.
This way, the string itself will be added instead of being strdup()'d.
And when the string_list is cleared, the string will be freed.

In d3115660b4 (branch: add flags and config to inherit tracking,

inheriting the tracking of another branch.
The new code, strdup()'d the remote_name of the existing branch, but
unfortunately it was not freed, producing a leak.
$ git remote add local .
$ git update-ref refs/remotes/local/foo HEAD
$ git branch --track bar local/foo
branch 'bar' set up to track 'local/foo'.
$ git branch --track=inherit baz bar
branch 'baz' set up to track 'local/foo'.

... in xstrdup wrapper.c
... in inherit_tracking branch.c
... in setup_tracking branch.c
... in create_branch branch.c

... in run_builtin git.c
Actually, the string we're strdup()'ing is from the struct branch

In c0192df630 (refspec: add support for negative refspecs, 2020-09-30)
query_matches_negative_refspec() was introduced.
The function was implemented as a two-loop process, where the former
loop accumulates and the latter evaluates. To accumulate, a string_list
is used.
Within the first loop, there are three cases where a string is added to
the string_list. Two of them add strings that do not need to be
freed. But in the third case, the string added is returned by
match_name_with_pattern(), which needs to be freed.
The string_list is initialized with STRING_LIST_INIT_NODUP, i.e. when
cleared, the strings added are not freed. Therefore, the string
returned by match_name_with_pattern() is not freed, so we have a leak.
$ git remote add local .

An interesting point to note is that while string_list_append() is used
in the first two cases described, string_list_append_nodup() is used in
the third. This seems to indicate an intention to delegate the
responsibility for freeing the string, to the string_list. As if the
string_list had been initialized with STRING_LIST_INIT_DUP, i.e. the
strings are strdup()'d when added (except if the "_nodup" API is used)
and freed when cleared.
Switching to STRING_LIST_INIT_DUP fixes the leak and probably is what we
wanted to do originally. Let's do it.

When opening a MIDX bitmap, we the pack-bitmap machinery eagerly calls
`prepare_midx_pack()` on each of the packs contained in the MIDX. This
is done in order to populate the array of `struct packed_git *`s held by
the MIDX, which we need later on in `load_reverse_index()`, since it
calls `load_pack_revindex()` on each of the MIDX'd packs, and requires
that the caller provide a pointer to a `struct packed_git`.
When opening one of these packs fails, the pack-bitmap code will `die()`
indicating that it can't open one of the packs in the MIDX. This
indicates that the MIDX is somehow broken with respect to the current
state of the repository. When this is the case, we indeed cannot make
use of the MIDX bitmap to speed up reachability traversals.
However, it does not mean that we can't perform reachability traversals
at all. In other failure modes, that same function calls `warning()` and
then returns -1, indicating to its caller (`open_bitmap()`) that we
should either look for a pack bitmap if one is available, or perform
normal object traversal without using bitmaps at all.
There is no reason why this case should cause us to die. If we instead
continued (by jumping to `cleanup` as this patch does) and avoid using
bitmaps altogether, we may again try and query the MIDX, which will also
fail. But when trying to call `fill_midx_entry()` fails, it also returns
a signal of its failure, and prompts the caller to try and locate the
object elsewhere.
In other words, the normal object traversal machinery works fine in the
presence of a corrupt MIDX, so there is no reason that the MIDX bitmap
machinery should abort in that case when we could easily continue.
Note that we *could* in theory try again to load a MIDX bitmap after
calling `reprepare_packed_git()`. Even though the `prepare_packed_git()`
code is careful to avoid adding a pack that we already have,
`prepare_midx_pack()` is not. So if we got part of the way through
calling `prepare_midx_pack()` on a stale MIDX, and then tried again on a
fresh MIDX that contains some of the same packs, we would end up with a
loop through the `->next` pointer.
For now, let's do the simplest thing possible and fallback to the
non-bitmap code when we detect a stale MIDX so that the complete fix as
above can be implemented carefully.

This patch introduces a new multi-valued configuration option,
`gc.recentObjectsHook` as a means to mark certain objects as recent (and
thus exempt from garbage collection), regardless of their age.
When performing a garbage collection operation on a repository with
unreachable objects, Git makes its decision on what to do with those
object(s) based on how recent the objects are or not. Generally speaking,
unreachable-but-recent objects stay in the repository, and older objects
are discarded.
However, we have no convenient way to keep certain precious, unreachable
objects around in the repository, even if they have aged out and would
be pruned. Our options today consist of:
- Point references at the reachability tips of any objects you
consider precious, which may be undesirable or infeasible if there
are many such objects.
- Track them via the reflog, which may be undesirable since the
reflog's lifetime is limited to that of the reference it's tracking
(and callers may want to keep those unreachable objects around for
longer).
- Extend the grace period, which may keep around other objects that
the caller *does* want to discard.
- Manually modify the mtimes of objects you want to keep. If those
objects are already loose, this is easy enough to do (you can just
enumerate and `touch -m` each one).
But if they are packed, you will either end up modifying the mtimes
of *all* objects in that pack, or be forced to write out a loose
copy of that object, both of which may be undesirable. Even worse,
if they are in a cruft pack, that requires modifying its `*.mtimes`
file by hand, since there is no exposed plumbing for this.
- Force the caller to construct the pack of objects they want
to keep themselves, and then mark the pack as kept by adding a
".keep" file. This works, but is burdensome for the caller, and
having extra packs is awkward as you roll forward your cruft pack.
This patch introduces a new option to the above list via the
`gc.recentObjectsHook` configuration, which allows the caller to
specify a program (or set of programs) whose output is treated as a set
of objects to treat as recent, regardless of their true age.
The implementation is straightforward. Git enumerates recent objects via
`add_unseen_recent_objects_to_traversal()`, which enumerates loose and
packed objects, and eventually calls add_recent_object() on any objects
for which `want_recent_object()`'s conditions are met.
This patch modifies the recency condition from simply "is the mtime of
this object more recent than the cutoff?" to "[...] or, is this object
mentioned by at least one `gc.recentObjectsHook`?".
Depending on whether or not we are generating a cruft pack, this allows
the caller to do one of two things:
- If generating a cruft pack, the caller is able to retain additional
objects via the cruft pack, even if they would have otherwise been
pruned due to their age.
- If not generating a cruft pack, the caller is likewise able to
retain additional objects as loose.
A potential alternative here is to introduce a new mode to alter the
contents of the reachable pack instead of the cruft one. One could
imagine a new option to `pack-objects`, say `--extra-reachable-tips`
that does the same thing as above, adding the visited set of objects
along the traversal to the pack.
But this has the unfortunate side-effect of altering the reachability
closure of that pack. If parts of the unreachable object graph mentioned
by one or more of the "extra reachable tips" programs is not closed,
then the resulting pack won't be either. This makes it impossible in the
general case to write out reachability bitmaps for that pack, since
closure is a requirement there.
Instead, keep these unreachable objects in the cruft pack (or set of
unreachable, loose objects) instead, to ensure that we can continue to
have a pack containing just reachable objects, which is always safe to
write a bitmap over.

When enumerating objects in order to add recent ones (i.e. those whose
mtime is strictly newer than the cutoff) as tips of a reachability
traversal, `add_recent_object()` discards objects which do not meet the
recency criteria.
The subsequent commit will make checking whether or not an object is
recent also consult the list of hooks in `pack.recentHook`. Isolate this
check in its own function to keep the additional complexity outside of
`add_recent_object()`.

To partition the set of packs based on which ones are "kept" (either
they have a .keep file, or were otherwise marked via the `--keep-pack`
option) and "non-kept" ones (anything else), `git repack` uses its
`collect_pack_filenames()` function.
Ordinarily, we would rely on a convenience function such as
`get_all_packs()` to enumerate and partition the set of packs. But
`collect_pack_filenames()` uses `readdir()` directly to read the
contents of the "$GIT_DIR/objects/pack" directory, and adds each entry
ending in ".pack" to the appropriate list (either kept, or non-kept as
above).
This is subtly racy, since `collect_pack_filenames()` may see a pack
that is not fully staged (i.e., it is missing its ".idx" file).
Ordinarily, this doesn't cause a problem. But it can cause issues when
generating a cruft pack.
This is because `git repack` feeds (among other things) the list of
existing kept packs down to `git pack-objects --cruft` to indicate that
any kept packs will not be removed from the repository (so that the
cruft pack machinery can avoid packing objects that appear in those
packs as cruft).
But `read_cruft_objects()` lists packfiles by calling `get_all_packs()`.
So if a ".pack" file exists (necessary to get that pack to appear to
`collect_pack_filenames()`), but doesn't have a corresponding ".idx"
file (necessary to get that pack to appear via `get_all_packs()`), we'll
complain with:
fatal: could not find pack '.tmp-5841-pack-a6b0150558609c323c496ced21de6f4b66589260.pack'
Fix the above by teaching `collect_pack_filenames()` to only collect
packs with their corresponding `*.idx` files in place, indicating that
those packs have been fully staged.
There are a couple of things worth noting:
- Since each entry in the `extra_keep` list (which contains the
`--keep-pack` names) has a `*.pack` suffix, we'll have to swap the
suffix from ".pack" to ".idx", and compare that instead.
- Since we use the the `fname_kept_list` to figure out which packs to
delete (with `git repack -d`), we would have previously deleted a
`*.pack` with no index (since the existince of a ".pack" file is
necessary and sufficient to include that pack in the list of
existing non-kept packs).
Now we will leave it alone (since that pack won't appear in the
list). This is far more correct behavior, since we don't want
to race with a pack being staged. Deleting a partially staged pack
is unlikely, however, since the window of time between staging a
pack and moving its .idx file into place is miniscule.
Note that this window does *not* include the time it takes to
receive and index the pack, since the incoming data goes into
"$GIT_DIR/objects/tmp_pack_XXXXXX", which does not end in ".pack"
and is thus ignored by collect_pack_filenames().
In the future, this function should probably be rewritten as a callback
to `for_each_file_in_pack_dir()`, but this is the simplest change we
could do in the short-term.

The 'read_replace_refs' global specifies whether or not we should
respect the references of the form 'refs/replace/<oid>' to replace which
object we look up when asking for '<oid>'. This global has caused issues
when it is not initialized properly, such as in b6551feadfd (merge-tree:
load default git config, 2023-05-10).
To make this more robust, move its config-based initialization out of
git_default_config and into prepare_repo_settings(). This provides a
repository-scoped version of the 'read_replace_refs' global.
The global still has its purpose: it is disabled process-wide by the
GIT_NO_REPLACE_OBJECTS environment variable or by a call to
disable_replace_refs() in some specific Git commands.
Since we already encapsulated the use of the constant inside
replace_refs_enabled(), we can perform the initialization inside that
method, if necessary. This solves the problem of forgetting to check the
config, as we will check it before returning this value.
Due to this encapsulation, the global can move to be static within
replace-object.c.
There is an interesting behavior change possible here: we now have a
repository-scoped understanding of this config value. Thus, if there was
a command that recurses into submodules and might follow replace refs,
then it would now respect the core.useReplaceRefs config value in each
repository.
'git grep --recurse-submodules' is such a command that recurses into
submodules in-process. We can demonstrate the granularity of this config
value via a test in t7814.

The 'read_replace_objects' constant is initialized by git_default_config
(if core.useReplaceRefs is disabled) and within setup_git_env (if
GIT_NO_REPLACE_OBJECTS) is set. To ensure that this variable cannot be
set accidentally in other places, wrap it in a replace_refs_enabled()
method.
Since we still assign this global in config.c, we are not able to remove
the global scope of this variable and make it a static within
replace-object.c. This will happen in a later change which will also
prevent the variable from being read before it is initialized.
Centralizing read access to the variable is an important first step.

Several builtins depend on being able to disable the replace references
so we actually operate on each object individually. These currently do
so by directly mutating the 'read_replace_refs' global.
A future change will move this global into a different place, so it will
be necessary to change all of these lines. However, we can simplify that
transition by abstracting the purpose of these global assignments with a
method call.
We will need to keep this read_replace_refs global forever, as we want
to make sure that we never use replace refs throughout the life of the
process if this method is called. Future changes may present a
repository-scoped version of the variable to represent that repository's
core.useReplaceRefs config value, but a zero-valued read_replace_refs
will always override such a setting.

In db9d67f2e9 (builtin/cat-file.c: support NUL-delimited input with
`-z`, 2022-07-22), we have introduced a new mode to read the input via
NUL-delimited records instead of newline-delimited records. This allows
the user to query for revisions that have newlines in their path
component. While unusual, such queries are perfectly valid and thus it
is clear that we should be able to support them properly.
Unfortunately, the commit only changed the input to be NUL-delimited,
but didn't change the output at the same time. While this is fine for
queries that are processed successfully, it is less so for queries that
aren't. In the case of missing commits for example the result can become
entirely unparsable:
```
$ printf "7ce4f05bae8120d9fa258e854a8669f6ea9cb7b1 blob 10\n1234567890\n\n\commit000" |
git cat-file --batch -z
7ce4f05bae8120d9fa258e854a8669f6ea9cb7b1 blob 10
1234567890
commit missing
```
This is of course a crafted query that is intentionally gaming the
deficiency, but more benign queries that contain newlines would have
similar problems.
Ideally, we should have also changed the output to be NUL-delimited when
`-z` is specified to avoid this problem. As the input is NUL-delimited,
it is clear that the output in this case cannot ever contain NUL
characters by itself. Furthermore, Git does not allow NUL characters in
revisions anyway, further stressing the point that using NUL-delimited
output is safe. The only exception is of course the object data itself,
but as git-cat-file(1) prints the size of the object data clients should
read until that specified size has been consumed.
But even though `-z` has only been introduced a few releases ago in Git
v2.38.0, changing the output format retroactively to also NUL-delimit
output would be a backwards incompatible change. And while one could
make the argument that the output is inherently broken already, we need
to assume that there are existing users out there that use it just fine
given that revisions containing newlines are quite exotic.
Instead, introduce a new option `-Z` that switches to NUL-delimited
input and output. While this new option could arguably only switch the
output format to be NUL-delimited, the consequence would be that users
have to always specify both `-z` and `-Z` when the input may contain
newlines. On the other hand, if the user knows that there never will be
newlines in the input, they don't have to use either of those options.
There is thus no usecase that would warrant treating input and output
format separately, which is why we instead opt to "do the right thing"
and have `-Z` mean to NUL-terminate both formats.
The old `-z` option is marked as deprecated with a hint that its output
may become unparsable. It is thus hidden both from the synopsis as well
as the command's help output.

Many of our commands support reading input that is separated either via
newlines or via NUL characters. Furthermore, in order to be a better
cross platform citizen, these commands typically know to strip the CRLF
sequence so that we also support reading newline-separated inputs on
e.g. the Windows platform. This results in the following kind of awkward
pattern:
```
struct strbuf input = STRBUF_INIT;
while (1) {
int ret;
if (nul_terminated)
ret = strbuf_getline_nul(&input, stdin);
else
ret = strbuf_getline(&input, stdin);
if (ret)
break;
...
}
```
Introduce a new CRLF-aware helper function that can read up to a user
specified delimiter. If the delimiter is `\n` the function knows to also
strip CRLF, otherwise it will only strip the specified delimiter. This
results in the following, much more readable code pattern:
```
struct strbuf input = STRBUF_INIT;
while (strbuf_getdelim_strip_crlf(&input, stdin, delim) != EOF) {
...
}
```

`test $A = $B` to compare expected and actual output. This has the
downside that it is impossible to tell what exactly is different between
both versions in case the test fails.
Refactor the tests to instead use `test_cmp`. While more verbose, it

In t1006 we have a bunch of tests that verify the output format of the

would include commit timestamps, we don't verify those but instead strip
them before comparing expected with actual results. This is done by the

ancient commit b335d3f121 (Add tests for git cat-file, 2008-04-23).
Our tests had been in a different shape back then. Most importantly we
didn't yet have the infrastructure to create objects with deterministic
timestamps. Nowadays we do though, and thus there is no reason anymore
to strip the timestamps.

The index is read in 'worktree.c' at two points:
1.The 'validate_no_submodules' function, which checks if there are any
submodules present in the worktree.
2.The 'check_clean_worktree' function, which verifies if a worktree is
'clean', i.e., there are no untracked or modified but uncommitted files.
This is done by running the 'git status' command, and an error message
is thrown if the worktree is not clean. Given that 'git status' is
already sparse-aware, the function is also sparse-aware.
Hence we can just set the requires-full-index to false for
"git worktree".
Add tests that verify that 'git worktree' behaves correctly when the
sparse index is enabled and test to ensure the index is not expanded.
The `p2000` tests demonstrate a ~20% execution time reduction for
'git worktree' using a sparse index:
(Note:the p2000 test results didn't reflect the huge speedup because of
the index reading time is minuscule comparing to the filesystem
operations.)

'bad-hooks/test-hook': ...", which causes the test to fail there.
We don't really care about the specific message text all that much here.
Use grep and a single regex with alternations to ascertain that we get
an error message (fatal or otherwise) about the failed invocation of the
hook, but don't bother checking if we get the right variant for the
platform the test is running on or whether quoting is done. This looser
check let's the test pass on NonStop OS.

592fc5b3 (dir.h: move DTYPE defines from cache.h, 2023-04-22) moved
DTYPE macros from cache.h to dir.h, but they are still used by cache.h
to implement ce_to_dtype(); cache.h cannot include dir.h because that
would cause name-hash.c to have two different and conflicting
definitions of `struct dir_entry`. (That should be separately fixed.)
Both dir.h and cache.h include statinfo.h, and this seems a reasonable
place for these definitions.
This change fixes a broken build issue on old SunOS.

Subject: [PATCH v2 2/2] add: test use of brackets when color is disabled
The interactive add command, 'git add -i', displays a menu of options
using full words. When color is enabled, the first letter of each word
is changed to a highlight color to signal that the first letter could be
used as a command. Without color, brackets ("[]") are used around these
first letters.
This behavior was not previously tested directly in t3701, so add a test
for it now. Since we use 'git add -i >actual <input' without
'force_color', the color system recognizes that colors are not available
on stdout and will be disabled by default.
This test would reproduce correctly with or without the fix in the
previous commit to make sure that color.ui is respected in 'git add'.

When 'git add -i' and 'git add -p' were converted to a builtin, they
introduced a color bug: the 'color.ui' config setting is ignored.
The included test demonstrates an example that is similar to the
previous test, which focuses on customizing colors. Here, we are
demonstrating that colors are not being used at all by comparing the raw
output and the color-decoded version of that output.
The fix is simple, to use git_color_default_config() as the fallback for
git_add_config(). A more robust change would instead encapsulate the
git_use_color_default global in methods that would check the config
setting if it has not been initialized yet. Some ideas are being
discussed on this front [1], but nothing has been finalized.
[1] https://lore.kernel.org/git/pull.1539.git.1685716420.gitgitgadget@gmail.com/
This test case naturally bisects down to 0527ccb1b55 (add -i: default to
the built-in implementation, 2021-11-30), but the fix makes it clear
that this would be broken even if we added the config to use the builtin
earlier than this.

Its better to document the struct members directly instead of on a
function that takes a pointer to the struct. This will also make it
easier to update the documentation in the future.
Make adjustments for this new context. Also drop “may contain” since we
don’t need to emphasize that a list could be empty.

Since the linux-asan-ubsan job runs using clang under Linux, there is
not much point in running a separate clang job. Any errors that a normal
clang compile-and-test cycle would find are likely to be a subset of
what the sanitizer job will find. Since this job takes ~14 minutes to
run in CI, this shaves off some of our CPU load (though it does not
affect end-to-end runtime, since it's typically run in parallel and is
not the longest job).
Technically this provides us with slightly less signal for a given run,
since you won't immediately know if a failure in the sanitizer job is
from using clang or from the sanitizers themselves. But it's generally
obvious from the logs, and anyway your next step would be to fix the
probvlem and re-run CI, since we expect all of these jobs to pass
normally.

When we started running sanitizers in CI via 1c0962c0c4 (ci: add address
and undefined sanitizer tasks, 2022-10-20), we ran them as two separate
CI jobs, since as that commit notes, the combination "seems to take
forever".
And indeed, it does with gcc. However, since the previous commit
switched to using clang, the situation is different, and we can save
some CPU by using a single job for both. Comparing before/after CI runs,
this saved about 14 minutes (the single combined job took 54m, versus
44m plus 24m for ASan and UBSan jobs, respectively). That's wall-clock
and not CPU, but since our jobs are mostly CPU-bound, the two should be
closely proportional.
This does increase the end-to-end time of a CI run, though, since before
this patch the two jobs could run in parallel, and the sanitizer job is
our longest single job. It also means that we won't get a separate
result for "this passed with UBSan but not with ASan" or vice versa).
But as 1c0962c0c4 noted, that is not a very useful signal in practice.
Below are some more detailed timings of gcc vs clang that I measured by
running the test suite on my local workstation. Each measurement counts
only the time to run the test suite with each compiler (not the compile
time itself). We'll focus on the wall-clock times for simplicity, though
the CPU times follow roughly similar trends.
Here's a run with CC=gcc as a baseline:
real 1m12.931s
user 9m30.566s
sys 8m9.538s
Running with SANITIZE=address increases the time by a factor of ~4.7x:
real 5m40.352s
user 49m37.044s
sys 36m42.950s
Running with SANITIZE=undefined increases the time by a factor of ~1.7x:
real 2m5.956s
user 12m42.847s
sys 19m27.067s
So let's call that 6.4 time units to run them separately (where a unit
is the time it takes to run the test suite with no sanitizers). As a
simplistic model, we might imagine that running them together would take
5.4 units (we save 1 unit because we are no longer running the test
suite twice, but just paying the sanitizer overhead on top of a single
run).
But that's not what happens. Running with SANITIZE=address,undefined
results in a factor of 9.3x:
real 11m9.817s
user 77m31.284s
sys 96m40.454s
So not only did we not get faster when doing them together, we actually
spent 1.5x as much CPU as doing them separately! And while those
wall-clock numbers might not look too terrible, keep in mind that this
is on an unloaded 8-core machine. In the CI environment, wall-clock
times will be much closer to CPU times. So not only are we wasting CPU,
but we risk hitting timeouts.
Now let's try the same thing with clang. Here's our no-sanitizer
baseline run, which is almost identical to the gcc one (which is quite
convenient, because we can keep using the same "time units" to get an
apples-to-apples comparison):
real 1m11.844s
user 9m28.313s
sys 8m8.240s
And now again with SANITIZE=address, we get a 5x factor (so slightly
worse than gcc's 4.7x, though I wouldn't read too much into it; there is
a fair bit of run-to-run noise):
real 6m7.662s
user 49m24.330s
sys 44m13.846s
And with SANITIZE=undefined, we are at 1.5x, slightly outperforming gcc
(though again, that's probably mostly noise):
real 1m50.028s
user 11m0.973s
sys 16m42.731s
So running them separately, our total cost is 6.5x. But if we combine
them in a single run (SANITIZE=address,undefined), we get:
real 6m51.804s
user 52m32.049s
sys 51m46.711s
which is a factor of 5.7x. That's along the lines we'd hoped for!
Running them together saves us almost a whole time unit. And that's not
counting any time spent outside the test suite itself (starting the job,
setting up the environment, compiling) that we're no longer duplicating
by having two jobs.
So clang behaves like we'd hope: the overhead to run the sanitizers is
additive as you add more sanitizers. Whereas gcc's numbers seem very
close to multiplicative, almost as if the sanitizers were enforcing
their overheads on each other (though that is purely a guess on what is
going on; ultimately what matters to us is the amount of time it takes).
And that roughly matches the CI improvement I saw. A "time unit" there
is more like 12 minutes, and the observed time savings was 14 minutes
(with the extra presumably coming from avoiding duplicated setup, etc).

Both gcc and clang support the "address" and "undefined" sanitizers.
However, they may produce different results. We've seen at least two
real world cases where gcc missed a UBSan problem but clang found it:
1. Clang's UBSan (using clang 14.0.6) found a string index that was
subtracted to "-1", causing an out-of-bounds read (curiously this
didn't trigger ASan, but that may be because the string was in the
argv memory, not stack or heap). Using gcc (version 12.2.0) didn't
find the same problem.
Original thread:
https://lore.kernel.org/git/20230519005447.GA2955320@coredump.intra.peff.net/
2. Clang's UBSan (using clang 4.0.1) complained about pointer
arithmetic with NULL, but gcc at the time did not. This was in
2017, and modern gcc does seem to find the issue, though.
Original thread:
https://lore.kernel.org/git/32a8b949-638a-1784-7fba-948ae32206fc@web.de/
Since we don't otherwise have a particular preference for one compiler
over the other for this test, let's switch to the one that we think may
be more thorough.
Note that it's entirely possible that the two are simply _different_,
and we are trading off problems that gcc would find that clang wouldn't.
However, my subjective and anecdotal experience has been that clang's
sanitizer support is a bit more mature (e.g., I recall other oddities
around leak-checking where clang performed more sensibly).
Obviously running both and cross-checking the results would give us the
best coverage, but that's very expensive to run (and these are already
some of our most expensive CI jobs). So let's use clang as our best
guess, and we can re-evaluate if we get more data points.

The --follow code doesn't handle most forms of pathspec magic. We check
that no unexpected ones have made it to try_to_follow_renames() with a
runtime GUARD_PATHSPEC() check, which gives behavior like this:
$ git log --follow ':(icase)makefile' >/dev/null
BUG: tree-diff.c:596: unsupported magic 10
Aborted
The same is true of ":(glob)", ":(attr)", and so on. It's good that we
notice the problem rather than continuing and producing a wrong answer.
But there are two non-ideal things:
1. The idea of GUARD_PATHSPEC() is to catch programming errors where
low-level code gets unexpected pathspecs. We'd usually try to catch
unsupported pathspecs by passing a magic_mask to parse_pathspec(),
which would give the user a much better message like:
pathspec magic not supported by this command: 'icase'
That doesn't happen here because git-log usually _does_ support
all types of pathspec magic, and so it passes "0" for the mask
(this call actually happens in setup_revisions()). It needs to
distinguish the normal case from the "--follow" one but currently
doesn't.
2. In addition to --follow, we have the log.follow config option. When
that is set, we try to turn on --follow mode only when there is a
single pathspec (since --follow doesn't handle anything else). But
really, that ought to be expanded to "use --follow when the
pathspec supports it". Otherwise, we'd complain any time you use an
exotic pathspec:
$ git config log.follow true
$ git log ':(icase)makefile' >/dev/null
BUG: tree-diff.c:596: unsupported magic 10
Aborted
We should instead just avoid enabling follow mode if it's not
supported by this particular invocation.
This patch expands our diff_check_follow_pathspec() function to cover
pathspec magic, solving both problems.
A few final notes:
- we could also solve (1) by passing the appropriate mask to
parse_pathspec(). But that's not great for two reasons. One is that
the error message is less precise. It says "magic not supported by
this command", but really it is not the command, but rather the
--follow option which is the problem. The second is that it always
calls die(). But for our log.follow code, we want to speculatively
ask "is this pathspec OK?" and just get a boolean result.
- This is obviously the right thing to do for ':(icase)' and most
other magic options. But ':(glob)' is a bit odd here. The --follow
code doesn't support wildcards, but we allow them anyway. From
try_to_follow_renames():
#if 0
/*
* We should reject wildcards as well. Unfortunately we
* haven't got a reliable way to detect that 'foo\*bar' in
* fact has no wildcards. nowildcard_len is merely a hint for
* optimization. Let it slip for now until wildmatch is taught
* about dry-run mode and returns wildcard info.
*/
if (opt->pathspec.has_wildcard)
BUG("wildcards are not supported");
#endif
So something like "git log --follow 'Make*'" is already doing the
wrong thing, since ":(glob)" behavior is already the default (it is
used only to countermand an earlier --noglob-pathspecs).
So we _could_ loosen the guard to allow :(glob), since it just
behaves the same as pathspecs do by default. But it seems like a
backwards step to do so. It already doesn't work (it hits the BUG()
case currently), and given that the user took an explicit step to
say "this pathspec should glob", it is reasonable for us to say "no,
--follow does not support globbing" (or in the case of log.follow,
avoid turning on follow mode). Which is what happens after this
patch.
- The set of allowed pathspec magic is obviously the same as in
GUARD_PATHSPEC(). We could perhaps factor these out to avoid
repetition. The point of having separate masks and GUARD calls is
that we don't necessarily know which parsed pathspecs will be used
where. But in this case, the two are heavily correlated. Still,
there may be some value in keeping them separate; it would make
anyone think twice about adding new magic to the list in
diff_check_follow_pathspec(). They'd need to touch
try_to_follow_renames() as well, which is the code that would
actually need to be updated to handle more exotic pathspecs.
- The documentation for log.follow says that it enables --follow
"...when a single <path> is given". We could possibly expand that to
say "with no unsupported pathspec magic", but that raises the
question of documenting which magic is supported. I think the
existing wording of "single <path>" sufficiently encompasses the
idea (the forbidden magic is stuff that might match multiple
entries), and the spirit remains the same.

In --follow mode, we require exactly one pathspec. We check this
condition in two places:
- in diff_setup_done(), we complain if --follow is used with an
inapropriate pathspec
- in git-log's revision "tweak" function, we enable log.follow only if
the pathspec allows it
The duplication isn't a big deal right now, since the logic is so
simple. But in preparation for it becoming more complex, let's pull it

When we have unsupported magic in a pathspec (because a command or code
path does not support particular items), we list the unsupported ones in
an error message.
Let's factor out the code here that converts the bits back into their
human-readable names, so that it can be used from other callers, which
may want to provide more flexible error messages.

Move 'repository_format_worktree_config' out of the global scope and into
the 'repository' struct. This change is similar to how
'repository_format_partial_clone' was moved in ebaf3bcf1ae (repository: move
global r_f_p_c to repo struct, 2021-06-17), adding it to the 'repository'
struct and updating 'setup.c' & 'repository.c' functions to assign the value
appropriately.
The primary goal of this change is to be able to load the worktree config of
a submodule depending on whether that submodule - not its superproject - has
'extensions.worktreeConfig' enabled. To ensure 'do_git_config_sequence()'
has access to the newly repo-scoped configuration, add a 'struct repository'
argument to 'do_git_config_sequence()' and pass it the 'repo' value from
'config_with_options()'.
Finally, add/update tests in 't3007-ls-files-recurse-submodules.sh' to
verify 'extensions.worktreeConfig' is read an used independently by
superprojects and submodules.

Add a 'struct repository' argument to 'config_with_options()' and remove the
'repo' field from 'struct git_config_source'.
A 'struct repository' instance was originally added to the config source in
e3e8bf046e9 (submodule-config: pass repo upon blob config read, 2021-08-16)
to improve how submodule blob config content was accessed. At the time, this
was the only use for a 'repository' instance, so it was naturally added only
where it was needed: to 'struct git_config_source'. However, in upcoming
patches, 'config_with_options()' will need the repository instance to access
extension information (regardless of whether a 'config_source' exists). To
make the 'struct repository' instance more easily accessible, move it into
the function's arguments.
Update all callers of 'config_with_options()' to pass the appropriate 'repo'
value:
* in 'builtin/config.c', use 'the_repository'
* in 'submodule--config.c', use the 'repo' arg in 'config_from_gitmodules()'
* in 'read_[very_]early_config()' & 'read_protected_config()', set 'repo' to
NULL (repository instances aren't available there)
* in 'populate_remote_urls()', use the repo instance that has been added to
the 'struct config_include_data'
* in 'repo_read_config()', use the given 'repo' arg
Finally, note that this patch eliminates the fallback to 'the_repository'
that previously existed for the 'config_source' repo instance if it was
NULL. The fallback is no longer necessary, as the 'repo' is set explicitly
in all cases where it is needed.

Update 'do_git_config_sequence()' to read the worktree config from
'config.worktree' in 'opts->git_dir' rather than the gitdir of
'the_repository'.
The worktree config is loaded from the path returned by
'git_pathdup("config.worktree")', the 'config.worktree' relative to the
gitdir of 'the_repository'. If loading the config for a submodule, this path
is incorrect, since 'the_repository' is the superproject. 'opts->git_dir' is
the gitdir of the submodule being configured, so the config file in that
location should be read instead.
To ensure the use of 'opts->git_dir' is safe, require that 'opts->git_dir'
is set if-and-only-if 'opts->commondir' is set (rather than "only-if" as it
is now). In all current usage of 'config_options', these values are set
together, so the stricter check does not change any behavior.
Finally, add tests to 't3007-ls-files-recurse-submodules.sh' to verify the
corrected config is loaded. Use 'ls-files' to test this because, unlike some
other '--recurse-submodules' commands, 'ls-files' parses the config of the
submodule in the same process as the superproject (via 'show_submodule()' ->
'repo_read_index()' -> 'prepare_repo_settings()'). As a result,
'the_repository' points to the config of the superproject but the
commondir/gitdir in the config sequence will be that of the submodule,
providing the exact scenario needed to verify this patch.
The first test ('--recurse-submodules parses submodule repo config') checks
that the submodule's *repo* config is read when running 'ls-files' on the
superproject; this confirms already-working behavior, serving as a reference
for how worktree config parsing should behave. The second test
('--recurse-submodules parses submodule worktree config') tests the same
scenario as the previous but instead using the *worktree* config,
demonstrating the corrected behavior. The 'test_config' helper is extended
for this case so that it properly applies the '--worktree' option to the
configure/unconfigure operations it performs.
Note that, although the submodule worktree config is now parsed instead of
the superproject's, 'extensions.worktreeConfig' in the superproject still
controls whether or not the worktree config is enabled at all in the
submodule. This will be fixed in a later patch.

t1092: update a write-tree test

In e0a862fdaf (submodule helper: convert relative URL to absolute URL if
needed, 2018-10-16), `prepare_to_clone_next_submodule()` lost the
ability to handle URL-less submodules, due to a change from:
if (repo_get_config_string_const(the_repostiory, sb.buf, &url))
url = sub->url;
to
if (repo_get_config_string_const(the_repostiory, sb.buf, &url)) {
if (starts_with_dot_slash(sub->url) ||
starts_with_dot_dot_slash(sub->url)) {
/* ... */
}
}
, which will segfault when `sub->url` is NULL, since both
`starts_with_dot_slash()` does not guard its arguments as non-NULL.
Guard the checks to both of the above functions by first checking
whether `sub->url` is non-NULL. There is no need to check whether `sub`
itself is NULL, since we already perform this check earlier in
`prepare_to_clone_next_submodule()`.
By adding a NULL-ness check on `sub->url`, we'll fall into the 'else'
branch, setting `url` to `sub->url` (which is NULL). Before attempting
to invoke `git submodule--helper clone`, check whether `url` is NULL,
and die() if it is.

"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 pseudoref AUTO_MERGE is documented since the previous commit. To
make it easier to use, let __git_refs in the Bash completion code
complete it.

Since 5291828df8 (merge-ort: write $GIT_DIR/AUTO_MERGE whenever we hit a
conflict, 2021-03-20), when using the 'ort' merge strategy, the special
ref AUTO_MERGE is written when a merge operation results in conflicts.
This ref points to a tree recording the conflicted state of the working
tree and is very useful during conflict resolution. However, this ref is
not documented.
Add some documentation for AUTO_MERGE in git-diff(1), git-merge(1),
gitrevisions(7) and in the user manual.
In git-diff(1), mention it at the end of the description section, when
we mention that the command also accepts trees instead of commits, and
also add an invocation to the "Various ways to check your working tree"
example.
In git-merge(1), add a step to the list of things that happen "when it
is not obvious how to reconcile the changes", under the "True merge"
section. Also mention AUTO_MERGE in the "How to resolve conflicts"
section, when mentioning 'git diff'.
In gitrevisions(7), add a mention of AUTO_MERGE along with the other
special refs.
In the user manual, add a paragraph describing AUTO_MERGE to the
"Getting conflict-resolution help during a merge" section, and include
an example of a 'git diff AUTO_MERGE' invocation for the example
conflict used in that section. Note that for uniformity we do not use
backticks around AUTO_MERGE here since the rest of the document does not
typeset special refs differently.

The "True merge" section of the 'git merge' documentation mentions that
in case of conflicts, the conflicted working tree files contain "the
result of the "merge" program". This probably refers to RCS's 'merge'
program, which is mentioned further down under "How conflicts are
presented".
Since it is not clear at that point of the document which program is
referred to, and since most modern readers probably do not relate to RCS
anyway, let's just write "the merge operation" instead.

Some special refs, namely HEAD, FETCH_HEAD, ORIG_HEAD, MERGE_HEAD and
CHERRY_PICK_HEAD, are mentioned and described in 'gitrevisions', but some
others, namely REBASE_HEAD, REVERT_HEAD, and BISECT_HEAD, are not.
Add a small description of these special refs.

The special refs listed in 'gitrevisions' (under the '<refname>' entry)
are on separate lines in the Asciidoc source, but end up as a single
continuous paragraph in the rendered documentation (see e.g. [1]). In
following commits we will mention additional special refs, so to improve
legibility, use a description list such that every entry appears on its
own line. Since we are already in a description list, use ':::' as the
term delimiter.
In order for the new description list to be aligned with the description
under the '<refname>' entry, instead of being aligned with the last
entry of the "in the following rules" nested list, use the "ancestor
list continuation" syntax [2], i.e., leave an empty line before the
continuation '+'. Do the same for the paragraph following the new
description list ("Note that any...").
While at it, also use a continuation '+' before the "in the following
rules" list, for correctness. The parser seems not to care here, but
it's best to keep the sources correct.
