Add a helpers function to handle the unlinking and writing
of the dir-diff submodule and symlink stand-in files.
Use the helpers to implement the guts of the hashmap loops.
This eliminate duplicate code and safeguards the submodules
hashmap loop against the symlink-chasing behavior that 5bafb3576a
(difftool: fix symlink-file writing in dir-diff mode, 2021-09-22)
addressed.
The submodules loop should not strictly require the unlink() call that
this is introducing to them, but it does not necessarily hurt them
either beyond the cost of the extra unlink().

The paths generated by difftool are passed to user-facing diff tools.
Using paths with repeated slashes in them is a cosmetic blemish that
is exposed to users and can be avoided.
Use a strbuf to create the buffer used for the dir-diff tmpdir.
Strip trailing slashes from the value read from TMPDIR to avoid
repeated slashes in the generated paths.
Adjust the error handling to avoid leaking strbufs and to avoid
returning -1 to cmd_main().

These changes are made in preparation of, the colorization support for the
"git log" subcommands that, rely on regex functionality (i.e. "--author",
"--committer" and "--grep"). These changes are necessary primarily because
match_one_pattern() expects header lines to be prefixed, however, in
pretty, the prefixes are stripped from the lines because the name-email
pairs need to go through additional parsing, before they can be printed and
because next_match() doesn't handle the case of
"ctx == GREP_CONTEXT_HEAD" at all. So, teach next_match() how to handle the
new case and move match_one_pattern()'s core logic to
headerless_match_one_pattern() while preserving match_one_pattern()'s uses
that depend on the additional processing.

In some circumstances, "git grep --textconv --recurse-submodules"
ignores the textconv attributes from the submodules and erroneously
applies the attributes defined in the superproject on the submodules'
files. The textconv cache is also saved on the superproject, even for
submodule objects.
A fix for these problems will probably require at least three changes:
- Some textconv and attributes functions (as well as their callees) will
have to be adjusted to work with arbitrary repositories. Note that
"fill_textconv()", for example, already receives a "struct repository"
but it writes the textconv cache using "write_loose_object()", which
implicitly works on "the_repository".
- grep.c functions will have to call textconv/userdiff routines passing
the "repo" field from "struct grep_source" instead of the one from
"struct grep_opt". The latter always points to "the_repository" on
"git grep" executions (see its initialization in builtin/grep.c), but
the former points to the correct repository that each source (an
object, file, or buffer) comes from.
- "userdiff_find_by_path()" might need to use a different attributes
stack for each repository it works on or reset its internal static
stack when the repository is changed throughout the calls.
For now, let's add some tests to demonstrate these problems, and also
update a NEEDSWORK comment in grep.h that mentions this bug to reference
the added tests.

When repacking into a geometric series and writing a multi-pack bitmap,
it is beneficial to have the largest resulting pack be the preferred
object source in the bitmap's MIDX, since selecting the large packs can
lead to fewer broken delta chains and better compression.
Teach 'git repack' to identify this pack and pass it to the MIDX write
machinery in order to mark it as preferred.

Teach `git repack` a new `--write-midx` option for callers that wish to
persist a multi-pack index in their repository while repacking.
There are two existing alternatives to this new flag, but they don't
cover our particular use-case. These alternatives are:
- Call 'git multi-pack-index write' after running 'git repack', or
- Set 'GIT_TEST_MULTI_PACK_INDEX=1' in your environment when running
'git repack'.
The former works, but introduces a gap in bitmap coverage between
repacking and writing a new MIDX (since the repack may have deleted a
pack included in the existing MIDX, invalidating it altogether).
Setting the 'GIT_TEST_' environment variable is obviously unsupported.
In fact, even if it were supported officially, it still wouldn't work,
because it generates the MIDX *after* redundant packs have been dropped,
leading to the same issue as above.
Introduce a new option which eliminates this race by teaching `git
repack` to generate the MIDX at the critical point: after the new packs
have been written and moved into place, but before the redundant packs
have been removed.
This option is compatible with `git repack`'s '--bitmap' option (it
changes the interpretation to be: "write a bitmap corresponding to the
MIDX after one has been generated").
There is a little bit of additional noise in the patch below to avoid
repeating ourselves when selecting which packs to delete. Instead of a
single loop as before (where we iterate over 'existing_packs', decide if
a pack is worth deleting, and if so, delete it), we have two loops (the
first where we decide which ones are worth deleting, and the second
where we actually do the deleting). This makes it so we have a single
check we can make consistently when (1) telling the MIDX which packs we
want to exclude, and (2) actually unlinking the redundant packs.
There is also a tiny change to short-circuit the body of
write_midx_included_packs() when no packs remain in the case of an empty
repository. The MIDX code does not handle this, so avoid trying to
generate a MIDX covering zero packs in the first place.

The new variable `existing_kept_packs` (and corresponding parameter
`fname_kept_list`) added by the previous patch make it seem like
`existing_packs` and `fname_list` are each subsets of the other two
respectively.
In reality, each pair is disjoint: one stores the packs without .keep
files, and the other stores the packs with .keep files. Rename each to
more clearly reflect this.

In order to be able to write a multi-pack index during repacking, `git
repack` must keep track of which packs it wants to write into the MIDX.
This set is the union of existing packs which will not be deleted,
new pack(s) generated as a result of the repack, and .keep packs.
Prior to this patch, `git repack` populated the list of existing packs
only when repacking all-into-one (i.e., with `-A` or `-a`), but we will
soon need to know this list when repacking when writing a MIDX without
a-i-o.
Populate the list of existing packs unconditionally, and guard removing
packs from that list only when repacking a-i-o.
Additionally, keep track of filenames of kept packs separately, since
this, too, will be used in an upcoming patch.

To figure out which commits we can write a bitmap for, the multi-pack
index/bitmap code does a reachability traversal, marking any commit
which can be found in the MIDX as eligible to receive a bitmap.
This approach will cause a problem when multi-pack bitmaps are able to
be generated from `git repack`, since the reference tips can change
during the repack. Even though we ignore commits that don't exist in
the MIDX (when doing a scan of the ref tips), it's possible that a
commit in the MIDX reaches something that isn't.
This can happen when a multi-pack index contains some pack which refers
to loose objects (e.g., if a pack was pushed after starting the repack
but before generating the MIDX which depends on an object which is
stored as loose in the repository, and by definition isn't included in
the multi-pack index).
By taking a snapshot of the references before we start repacking, we can
close that race window. In the above scenario (where we have a packed
object pointing at a loose one), we'll either (a) take a snapshot of the
references before seeing the packed one, or (b) take it after, at which
point we can guarantee that the loose object will be packed and included
in the MIDX.
This patch does just that. It writes a temporary "reference snapshot",
which is a list of OIDs that are at the ref tips before writing a
multi-pack bitmap. References that are "preferred" (i.e,. are a suffix
of at least one value of the 'pack.preferBitmapTips' configuration) are
marked with a special '+'.
The format is simple: one line per commit at each tip, with an optional
'+' at the beginning (for preferred references, as described above).
When provided, the reference snapshot is used to drive bitmap selection
instead of the MIDX code doing its own traversal. When it isn't
provided, the usual traversal takes place instead.

To power a new `--write-midx` mode, `git repack` will want to write a
multi-pack index containing a certain set of packs in the repository.
This new option will be used by `git repack` to write a MIDX which
contains only the packs which will survive after the repack (that is, it
will exclude any packs which are about to be deleted).
This patch effectively exposes the function implemented in the previous
commit via the `git multi-pack-index` builtin. An alternative approach
would have been to call that function from the `git repack` builtin
directly, but this introduces awkward problems around closing and
reopening the object store, so the MIDX will be written out-of-process.

This will be used in an upcoming patch to power a new `--stdin-packs`
mode of `git multi-pack-index write` for callers that only want to
include certain packs in a MIDX (and ignore any packs which may have
happened to enter the repository independently, e.g., from pushes).

6a8cbc41ba (developer: enable pedantic by default, 2021-09-03)
enables pedantic mode in as many compilers as possible to help gather
feedback on future tightening, so lets do so.
-Wpedantic is missing in some really old gcc 4 versions so lets restrict
it to gcc5 and clang4 (it does work in clang3 AFAIK, but it will be
unlikely that a developer will use such an old compiler anyway).
MinGW gcc is the only one which has -Wno-pedantic-ms-format, and while
that is available also in older compilers, the Windows SDK provides gcc10
so lets aim for that.
Note that in order to target the flag to only Windows, additional changes
were needed in config.mak.uname to propagate the OS detection which also
did some minor refactoring, but which is functionaly equivalent.

Fix a bad landmine of a bug which has been with us ever since
PARSE_OPT_SHELL_EVAL was added in 47e9cd28f8a (parseopt: wrap
rev-parse --parseopt usage for eval consumption, 2010-06-12).
It's an argument to parse_options() and should therefore be in "enum
parse_opt_flags", but it was added to the per-option "enum
parse_opt_option_flags" by mistake.
Therefore as soon as we'd have an enum member in the former that
reached its value of "1 << 8" we'd run into a seemingly bizarre bug
where that new option would turn on the unrelated PARSE_OPT_SHELL_EVAL
in "git rev-parse --parseopt" by proxy.
I manually checked that no other enum members suffered from such
overlap, by setting the values to non-overlapping values, and making
the relevant codepaths BUG() out if the given value was above/below
the expected (excluding flags=0 in the case of "enum
parse_opt_flags").

The git_config_key_is_valid() function got left behind in a
refactoring in a9bcf6586d1 (alias: use the early config machinery to
expand aliases, 2017-06-14),
It previously had two users when it was added in 9e9de18f1ad (config:

after 6a1e1bc0a15 (pager: use callbacks instead of configset,
2016-09-12) only one remained.
By removing it we can get rid of the "quiet" branches in this
function, as well as cases where "store_key" is NULL, for which there
are no other users.
Out of the 5 callers of git_config_parse_key() only one needs to pass
a non-NULL "size_t *baselen_", so we could remove the third parameter
from the public interface. I did not find that potential
simplification to be worthwhile.

The previous changes modified the behavior of 'git add', 'git rm', and
'git mv' to not adjust paths outside the sparse-checkout cone, even if
they exist in the working tree and their cache entries lack the
SKIP_WORKTREE bit. The intention is to warn users that they are doing
something potentially dangerous. The '--sparse' option was added to each
command to allow careful users the same ability they had before.
To improve the discoverability of this new functionality, add a message

include possibly a list of paths instead of only a list of pathspecs.

Since cmd_mv() does not operate on cache entries and instead directly
checks the filesystem, we can only use path_in_sparse_checkout() as a
mechanism for seeing if a path is sparse or not. Be sure to skip
returning a failure if '-k' is specified.
To ensure that the advice around sparse paths is the only reason a move
failed, be sure to check this as the very last thing before inserting
into the src_for_dst list.
The tests cover a variety of cases such as whether the target is tracked
or untracked, and whether the source or destination are in or outside of
the sparse-checkout definition.

If a path does not match the sparse-checkout cone but is somehow missing
the SKIP_WORKTREE bit, then 'git rm' currently succeeds in removing the
file. One reason a user might be in this situation is a merge conflict
outside of the sparse-checkout cone. Removing such a file might be
problematic for users who are not sure what they are doing.
Add a check to path_in_sparse_checkout() when 'git rm' is checking if a
path should be considered for deletion. Of course, this check is ignored
if the '--sparse' option is specified, allowing users who accept the
risks to continue with the removal.
This also removes a confusing behavior where a user asks for a directory
to be removed, but only the entries that are within the sparse-checkout
definition are removed. Now, 'git rm <dir>' will fail without '--sparse'
and will succeed in removing all contained paths with '--sparse'.

We previously modified 'git add' to refuse updating index entries
outside of the sparse-checkout cone. This is justified to prevent users
from accidentally getting into a confusing state when Git removes those
files from the working tree at some later point.
Unfortunately, this caused some workflows that were previously possible
to become impossible, especially around merge conflicts outside of the
sparse-checkout cone. These were documented in tests within t1092.
We now re-enable these workflows using a new '--sparse' option to 'git
add'. This allows users to signal "Yes, I do know what I'm doing with
these files," and accept the consequences of the files leaving the
worktree later.
We delay updating the advice message until implementing a similar option

When 'git add' adds a tracked file that is outside of the
sparse-checkout cone, it checks the SKIP_WORKTREE bit to see if the file
exists outside of the sparse-checkout cone. This is usually correct,
except in the case of a merge conflict outside of the cone.
Modify add_pathspec_matched_against_index() to be more careful about
paths by checking the sparse-checkout patterns in addition to the
SKIP_WORKTREE bit. This causes 'git add' to no longer allow files
outside of the cone that removed the SKIP_WORKTREE bit due to a merge
conflict.
With only this change, users will only be able to add the file after
adding the file to the sparse-checkout cone. A later change will allow
users to force adding even though the file is outside of the
sparse-checkout cone.

The add_files() method in builtin/add.c takes a set of untracked files
that are being added by the input pathspec and inserts them into the

gain the SKIP_WORKTREE bit at some point. However, this was not checked
before inserting into the index, so these files are added even though we
want to avoid modifying the index outside of the sparse-checkout cone.

Within match_pathname(), one successful matching category happens when
the pattern is equal to its non-wildcard prefix. At this point, we have
checked that the input 'pathname' matches the pattern up to the prefix
length, and then we subtraced that length from both 'patternlen' and
'namelen'.
In the case of a directory match, this prefix match should be
sufficient. However, the success condition only cared about _exact_
equality here. Instead, we should allow any path that agrees on this
prefix in the case of PATTERN_FLAG_MUSTBEDIR.
This case was not tested before because of the way unpack_trees() would
match a parent directory before visiting the contained paths. This
approach is changing, so we must change this comparison.

When matching a path against a list of patterns, the ones that require a
directory match previously did not work when a filename is specified.
This was fine when all pattern-matching was done within methods such as
unpack_trees() that check a directory before recursing into the
contained files. However, other commands will start matching individual
files against pattern lists without that recursive approach.
The last_matching_pattern_from_list() logic performs some checks on the
filetype of a path within the index when the PATTERN_FLAG_MUSTBEDIR flag
is set. This works great when setting SKIP_WORKTREE bits within
unpack_trees(), but doesn't work well when passing an arbitrary path
such as a file within a matching directory.
We extract the logic around determining the file type, but attempt to
avoid checking the filesystem if the parent directory already matches
the sparse-checkout patterns. The new path_matches_dir_pattern() method
includes a 'path_parent' parameter that is used to store the parent
directory of 'pathname' between multiple pattern matching tests. This is
loaded lazily, only on the first pattern it finds that has the
PATTERN_FLAG_MUSTBEDIR flag.
If we find that a path has a parent directory, we start by checking to
see if that parent directory matches the pattern. If so, then we do not
need to query the index for the type (which can be expensive). If we
find that the parent does not match, then we still must check the type
from the index for the given pathname.
Note that this does not affect cone mode pattern matching, but instead
the more general -- and slower -- full pattern set. Thus, this does not

Add some tests to demonstrate the current behavior around adding files
outside of the sparse-checkout cone. Currently, untracked files are
handled differently from tracked files. A future change will make these
cases be handled the same way.
Further expand checking that a failed 'git add' does not stage changes
to the index.

Commit b681b191 introduced the support of systemd timers for git
maintenance.
A test is leveraging the `systemd-analyze verify` utility to verify the
correctness of the systemd unit files generated by git.
But on some systems, although the `systemd-analyze` tool is installed
and supports the `verify` subcommand, it fails with some permission
errors.
So, instead of only checking if the `verify` subcommand exists, a more
reliable way of detecting whether `systemd-analyze verify` can be used
is to try to use it.
The SYSTEMD_ANALYZE prerequisite is now trying to run `systemd-analyze
verify` on a systemd unit file which is shipped by systemd itself.
We can reasonably think that, on systemd hosts, this file is present and
valid.

Remove the commit_info_init() function addded in ea02ffa3857 (mailmap:
simplify map_user() interface, 2013-01-05) and instead initialize the
"struct commit_info" with a macro.
This is the more idiomatic pattern in the codebase, and doesn't leave
us wondering when we see the *_init() function if this struct needs
more complex initialization than a macro can provide.
The get_commit_info() function is only called by the three callers
being changed here immediately after initializing the struct with the
macros, so by moving the initialization to the callers we don't need
to do it in get_commit_info() anymore.

*.h: move some *_INIT to designated initializers
*.h _INIT macros: don't specify fields equal to 0

Use the same pattern for cb_init() as the one established in the
recent refactoring of other such patterns in
5726a6b4012 (*.c *_init(): define in terms of corresponding *_INIT
macro, 2021-07-01).
It has been pointed out[1] that we could perhaps use this C99
replacement of using a compound literal for all of these:
*t = (struct cb_tree){ 0 };
But let's just stick to the existing pattern established in
5726a6b4012 for now, we can leave another weather balloon for some
other time.

Move various *_INIT macros to use designated initializers. This helps
readability. I've only picked those leftover macros that were not
touched by another in-flight series of mine which changed others, but
also how initialization was done.
In the case of SUBMODULE_ALTERNATE_SETUP_INIT I've left an explicit
initialization of "error_mode", even though
SUBMODULE_ALTERNATE_ERROR_IGNORE itself is defined as "0". Let's not
peek under the hood and assume that enum fields we know the value of
will stay at "0".
The change to "TESTSUITE_INIT" in "t/helper/test-run-command.c" was
part of an earlier on-list version[1] of c90be786da9 (test-tool
run-command: fix flip-flop init pattern, 2021-09-11).

Change the initialization of "struct strbuf" changed in
cbc0f81d96f (strbuf: use designated initializers in STRBUF_INIT,
2017-07-10) to omit specifying "alloc" and "len", as we do with other
"alloc" and "len" (or "nr") in similar structs.
Let's likewise omit the explicit initialization of all fields in the
"struct ipc_client_connect_option" struct added in
59c7b88198a (simple-ipc: add win32 implementation, 2021-03-15).
Do the same for a few other initializers, e.g. STRVEC_INIT and
CACHE_DEF_INIT.
Finally, start incrementally changing the same pattern in
"t/helper/test-run-command.c". This change was part of an earlier
on-list version[1] of c90be786da9 (test-tool run-command: fix
flip-flop init pattern, 2021-09-11).

In C it isn't required to specify that all members of a struct are
zero'd out to 0, NULL or '\0', just providing a "{ 0 }" will
accomplish that.
Let's also change code that provided N zero'd fields to just
provide one, and change e.g. "{ NULL }" to "{ 0 }" for
consistency. I.e. even if the first member is a pointer let's use "0"
instead of "NULL". The point of using "0" consistently is to pick one,
and to not have the reader wonder why we're not using the same pattern
everywhere.
