John Cai 7d3d226e70 reflog: libify delete reflog function and helpers
Currently stash shells out to reflog in order to delete refs. In an
effort to reduce how much we shell out to a subprocess, libify the
functionality that stash needs into reflog.c.

Add a reflog_delete function that is pretty much the logic in the while
loop in builtin/reflog.c cmd_reflog_delete(). This is a function that
builtin/reflog.c and builtin/stash.c can both call.

Also move functions needed by reflog_delete and export them.

Ævar Arnfjörð Bjarmason 244c27242f diff.[ch]: have diff_free() call clear_pathspec(opts.pathspec)
Have the diff_free() function call clear_pathspec(). Since the
diff_flush() function calls this all its callers can be simplified to
rely on it instead.

When I added the diff_free() function in e900d494dc (diff: add an API
for deferred freeing, 2021-02-11) I simply missed this, or wasn't
interested in it. Let's consolidate this now. This means that any
future callers (and I've got revision.c in mind) that embed a "struct
diff_options" can simply call diff_free() instead of needing know that
it has an embedded pathspec.

This does fix a bunch of leaks, but I can't mark any test here as
passing under the SANITIZE=leak testing mode because in
886e1084d7 (builtin/: add UNLEAKs, 2017-10-01) an UNLEAK(rev) was
added, which plasters over the memory
leak. E.g. "t4011-diff-symlink.sh" would report fewer leaks with this
fix, but because of the UNLEAK() reports none.

I'll eventually loop around to removing that UNLEAK(rev) annotation as
I'll fix deeper issues with the revisions API leaking. This is one
small step on the way there, a new freeing function in revisions.c
will want to call this diff_free().

Ævar Arnfjörð Bjarmason 88c7b4c3c8 date API: create a date.h, split from cache.h
Move the declaration of the date.c functions from cache.h, and adjust
the relevant users to include the new date.h header.

The show_ident_date() function belonged in pretty.h (it's defined in
pretty.c), its two users outside of pretty.c didn't strictly need to
include pretty.h, as they get it indirectly, but let's add it to them
anyway.

Similarly, the change to "builtin/{fast-import,show-branch,tag}.c"
isn't needed as far as the compiler is concerned, but since they all
use the "DATE_MODE()" macro we now define in date.h, let's have them
include it.

We could simply include this new header in "cache.h", but as this
change shows these functions weren't common enough to warrant
including in it in the first place. By moving them out of cache.h
changes to this API will no longer cause a (mostly) full re-build of
the project when "make" is run.

Ævar Arnfjörð Bjarmason 04bf052eef grep: simplify config parsing and option parsing
Simplify the parsing of "grep.patternType" and
"grep.extendedRegexp". This changes no behavior, but gets rid of
complex parsing logic that isn't needed anymore.

When "grep.patternType" was introduced in 84befcd0a4 (grep: add a
grep.patternType configuration setting, 2012-08-03) we promised that:

 1. You can set "grep.patternType", and "[setting it to] 'default'
    will return to the default matching behavior".

    In that context "the default" meant whatever the configuration
    system specified before that change, i.e. via grep.extendedRegexp.

 2. We'd support the existing "grep.extendedRegexp" option, but ignore
    it when the new "grep.patternType" option is set. We said we'd
    only ignore the older "grep.extendedRegexp" option "when the
    `grep.patternType` option is set to a value other than
    'default'".

In a preceding commit we changed grep_config() to be called after
grep_init(), which means that much of the complexity here can go
away.

As before both "grep.patternType" and "grep.extendedRegexp" are
last-one-wins variable, with "grep.extendedRegexp" yielding to
"grep.patternType", except when "grep.patternType=default".

Note that as the previously added tests indicate this cannot be done
on-the-fly as we see the config variables, without introducing more
state keeping. I.e. if we see:

    -c grep.extendedRegexp=false
    -c grep.patternType=default
    -c extendedRegexp=true

We need to select ERE, since grep.patternType=default unselects that
variable, which normally has higher precedence, but we also need to
select BRE in cases of:

    -c grep.extendedRegexp=true \
    -c grep.extendedRegexp=false

Which would not be the case for this, which select ERE:

    -c grep.patternType=extended \
    -c grep.extendedRegexp=false

Therefore we cannot do this on-the-fly in grep_config without also
introducing tracking variables for not only the pattern type, but what
the source of that pattern type was.

So we need to decide on the pattern after our config was fully
parsed. Let's do that by deferring the decision on the pattern type
until it's time to compile it in compile_regexp().

By that time we've not only parsed the config, but also handled the
command-line options. Those will set "opt.pattern_type_option" (*not*
"opt.extended_regexp_option"!).

At that point all we need to do is see if "grep.patternType" was
UNSPECIFIED in the end (including an explicit "=default"), if so we'll
use the "grep.extendedRegexp" configuration, if any.

See my 07a3d41173 (grep: remove regflags from the public grep_opt
API, 2017-06-29) for addition of the two comments being removed here,
i.e. the complexity noted in that commit is now going away.

Ævar Arnfjörð Bjarmason 72365bb499 grep API: call grep_config() after grep_init()
The grep_init() function used the odd pattern of initializing the
passed-in "struct grep_opt" with a statically defined "grep_defaults"
struct, which would be modified in-place when we invoked
grep_config().

So we effectively (b) initialized config, (a) then defaults, (c)
followed by user options. Usually those are ordered as "a", "b" and
"c" instead.

As the comments being removed here show the previous behavior needed
to be carefully explained as we'd potentially share the populated
configuration among different instances of grep_init(). In practice we
didn't do that, but now that it can't be a concern anymore let's
remove those comments.

This does not change the behavior of any of the configuration
variables or options. That would have been the case if we didn't move
around the grep_config() call in "builtin/log.c". But now that we call
"grep_config" after "git_log_config" and "git_format_config" we'll
need to pass in the already initialized "struct grep_opt *".

See 6ba9bb76e0 (grep: copy struct in one fell swoop, 2020-11-29) and
7687a0541e (grep: move the configuration parsing logic to grep.[ch],
2012-10-09) for the commits that added the comments.

The memcpy() pattern here will be optimized away and follows the
convention of other *_init() functions. See 5726a6b401 (*.c *_init():
define in terms of corresponding *_INIT macro, 2021-07-01).

Ævar Arnfjörð Bjarmason 9725c8dda2 built-ins: trust the "prefix" from run_builtin()
Change code in "builtin/grep.c" and "builtin/ls-tree.c" to trust the
"prefix" passed from "run_builtin()". The "prefix" we get from setup.c
is either going to be NULL or a string of length >0, never "".

So we can drop the "prefix && *prefix" checks added for
"builtin/grep.c" in 0d042fecf2 (git-grep: show pathnames relative to
the current directory, 2006-08-11), and for "builtin/ls-tree.c" in
a69dd585fc (ls-tree: chomp leading directories when run from a
subdirectory, 2005-12-23).

As seen in code in revision.c that was added in cd676a5136 (diff
--relative: output paths as relative to the current subdirectory,
2008-02-12) we already have existing code that does away with this
assertion.

This makes it easier to reason about a subsequent change to the
"prefix_length" code in grep.c in a subsequent commit, and since we're
going to the trouble of doing that let's leave behind an assert() to
promise this to any future callers.

For "builtin/grep.c" it would be painful to pass the "prefix" down the
callchain of:

    cmd_grep -> grep_tree -> grep_submodule -> grep_cache -> grep_oid ->
    grep_source_name

So for the code that needs it in grep_source_name() let's add a
"grep_prefix" variable similar to the existing "ls_tree_prefix".

While at it let's move the code in cmd_ls_tree() around so that we
assign to the "ls_tree_prefix" right after declaring the variables,
and stop assigning to "prefix". We only subsequently used that
variable later in the function after clobbering it. Let's just use our
own "grep_prefix" instead.

Let's also add an assert() in git.c, so that we'll make this promise
about the "prefix" to any current and future callers, as well as to
any readers of the code.

Code history:

 * The strlen() in "grep.c" hasn't been used since 493b7a08d8 (grep:
   accept relative paths outside current working directory, 2009-09-05).

   When that code was added in 0d042fecf2 (git-grep: show pathnames
   relative to the current directory, 2006-08-11) we used the length.

   But since 493b7a08d8 we haven't used it for anything except a
   boolean check that we could have done on the "prefix" member
   itself.

Patrick Steinhardt b18aaaa5e9 fetch: skip computing output width when not printing anything
When updating references via git-fetch(1), then by default we report to
the user which references have been changed. This output is formatted in
a nice table such that the different columns are aligned. Because the
first column contains abbreviated object IDs we thus need to iterate
over all refs which have changed and compute the minimum length for
their respective abbreviated hashes. While this effort makes sense in
most cases, it is wasteful when the user passes the `--quiet` flag: we
don't print the summary, but still compute the length.

Skip computing the summary width when the user asked for us to be quiet.
This gives us a speedup of nearly 10% when doing a mirror-fetch in a
repository with thousands of references being updated:

    Benchmark 1: git fetch --quiet +refs/*:refs/* (HEAD~)
      Time (mean ± σ):     96.078 s ±  0.508 s    [User: 91.378 s, System: 10.870 s]
      Range (min … max):   95.449 s … 96.760 s    5 runs

    Benchmark 2: git fetch --quiet +refs/*:refs/* (HEAD)
      Time (mean ± σ):     88.214 s ±  0.192 s    [User: 83.274 s, System: 10.978 s]
      Range (min … max):   87.998 s … 88.446 s    5 runs

    Summary
      'git fetch --quiet +refs/*:refs/* (HEAD)' ran
        1.09 ± 0.01 times faster than 'git fetch --quiet +refs/*:refs/* (HEAD~)'

Josh Steadmon f05da2b48b clone, submodule: pass partial clone filters to submodules
When cloning a repo with a --filter and with --recurse-submodules
enabled, the partial clone filter only applies to the top-level repo.
This can lead to unexpected bandwidth and disk usage for projects which
include large submodules. For example, a user might wish to make a
partial clone of Gerrit and would run:
`git clone --recurse-submodules --filter=blob:5k https://gerrit.googlesource.com/gerrit`.
However, only the superproject would be a partial clone; all the
submodules would have all blobs downloaded regardless of their size.
With this change, the same filter can also be applied to submodules,
meaning the expected bandwidth and disk savings apply consistently.

To avoid changing default behavior, add a new clone flag,
`--also-filter-submodules`. When this is set along with `--filter` and
`--recurse-submodules`, the filter spec is passed along to git-submodule
and git-submodule--helper, such that submodule clones also have the
filter applied.

This applies the same filter to the superproject and all submodules.
Users who need to customize the filter per-submodule would need to clone
with `--no-recurse-submodules` and then manually initialize each
submodule with the proper filter.

Applying filters to submodules should be safe thanks to Jonathan Tan's
recent work [1, 2, 3] eliminating the use of alternates as a method of
accessing submodule objects, so any submodule object access now triggers
a lazy fetch from the submodule's promisor remote if the accessed object
is missing. This patch is a reworked version of [4], which was created
prior to Jonathan Tan's work.

Johannes Schindelin 059fda1902 checkout/fetch/pull/pack-objects: allow `-h` outside a repository
When we taught these commands about the sparse index, we did not account
for the fact that the `cmd_*()` functions _can_ be called without a
gitdir, namely when `-h` is passed to show the usage.

A plausible approach to address this is to move the
`prepare_repo_settings()` calls right after the `parse_options()` calls:
The latter will never return when it handles `-h`, and therefore it is
safe to assume that we have a `gitdir` at that point, as long as the
built-in is marked with the `RUN_SETUP` flag.

However, it is unfortunately not that simple. In `cmd_pack_objects()`,
for example, the repo settings need to be fully populated so that the
command-line options `--sparse`/`--no-sparse` can override them, not the
other way round.

Therefore, we choose to imitate the strategy taken in `cmd_diff()`,
where we simply do not bother to prepare and initialize the repo
settings unless we have a `gitdir`.

This fixes https://github.com/git-for-windows/git/issues/3688

Derrick Stolee 53255916b7 worktree: copy sparse-checkout patterns and config on add
When adding a new worktree, it is reasonable to expect that we want to
use the current set of sparse-checkout settings for that new worktree.
This is particularly important for repositories where the worktree would
become too large to be useful. This is even more important when using
partial clone as well, since we want to avoid downloading the missing
blobs for files that should not be written to the new worktree.

The only way to create such a worktree without this intermediate step of
expanding the full worktree is to copy the sparse-checkout patterns and
config settings during 'git worktree add'. Each worktree has its own
sparse-checkout patterns, and the default behavior when the
sparse-checkout file is missing is to include all paths at HEAD. Thus,
we need to have patterns from somewhere, they might as well be the
current worktree's patterns. These are then modified independently in
the future.

In addition to the sparse-checkout file, copy the worktree config file
if worktree config is enabled and the file exists. This will copy over
any important settings to ensure the new worktree behaves the same as
the current one. The only exception we must continue to make is that
core.bare and core.worktree should become unset in the worktree's config
file.

Derrick Stolee 7316dc5f6f sparse-checkout: set worktree-config correctly
`git sparse-checkout set/init` enables worktree-specific
configuration[*] by setting extensions.worktreeConfig=true, but neglects
to perform the additional necessary bookkeeping of relocating
`core.bare=true` and `core.worktree` from $GIT_COMMON_DIR/config to
$GIT_COMMON_DIR/config.worktree, as documented in git-worktree.txt. As a
result of this oversight, these settings, which are nonsensical for
secondary worktrees, can cause Git commands to incorrectly consider a
worktree bare (in the case of `core.bare`) or operate on the wrong
worktree (in the case of `core.worktree`). Fix this problem by taking
advantage of the recently-added init_worktree_config() which enables
`extensions.worktreeConfig` and takes care of necessary bookkeeping.

While at it, for backward-compatibility reasons, also stop upgrading the
repository format to "1" since doing so is (unintentionally) not
required to take advantage of `extensions.worktreeConfig`, as explained
by 11664196ac ("Revert "check_repository_format_gently(): refuse
extensions for old repositories"", 2020-07-15).

[*] The main reason to use worktree-specific config for the
sparse-checkout builtin was to avoid enabling sparse-checkout patterns
in one and causing a loss of files in another. If a worktree does not
have a sparse-checkout patterns file, then the sparse-checkout logic
will not kick in on that worktree.

Ævar Arnfjörð Bjarmason f36d4f8316 ls-remote & transport API: release "struct transport_ls_refs_options"
Fix a memory leak in codepaths that use the "struct
transport_ls_refs_options" API. Since the introduction of the struct
in 39835409d1 (connect, transport: encapsulate arg in struct,
2021-02-05) the caller has been responsible for freeing it.

That commit in turn migrated code originally added in
402c47d939 (clone: send ref-prefixes when using protocol v2,
2018-07-20) and b4be74105f (ls-remote: pass ref prefixes when
requesting a remote's refs, 2018-03-15). Only some of those codepaths
were releasing the allocated resources of the struct, now all of them
will.

Mark the "t/t5511-refspec.sh" test as passing when git is compiled
with SANITIZE=leak. They'll now be listed as running under the
"GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode (the "linux-leaks" CI
target). Previously 24/47 tests would fail.
