df53c80822 stash: make sure we have a valid index before writing it
In 'do_apply_stash()' we refresh the index in the end.  Since
34933d0eff ("stash: make sure to write refreshed cache", 2019-09-11),
we also write that refreshed index when --quiet is given to 'git stash
apply'.

However if '--index' is not given to 'git stash apply', we also
discard the index in the else clause just before.  We need to do so
because we use an external 'git update-index --add --stdin', which
leads to an out of date in-core index.

Later we call 'refresh_and_write_cache', which now leads to writing
the discarded index, which means we essentially write an empty index
file.  This is obviously not correct, or the behaviour the user
wanted.  We should not modify the users index without being asked to
do so.

Make sure to re-read the index after discarding the current in-core
index, to avoid dealing with outdated information.  Instead we could
also drop the 'discard_cache()' + 'read_cache()', however that would
make it easy to fall into the same trap as 34933d0eff did, so it's
better to avoid that.

We can also drop the 'refresh_and_write_cache' completely in the quiet
case.  Previously in legacy stash we relied on 'git status' to refresh
the index after calling 'git read-tree' when '--index' was passed to
'git apply'.  However the 'reset_tree()' call that replaced 'git
read-tree' always passes options that are equivalent to '-m', making
the refresh of the index unnecessary.

4a58c3d7f7 stash: handle staged changes in skip-worktree files correctly
When calling `git stash` while changes were staged for files that are
marked with the `skip-worktree` bit (e.g. files that are excluded in a
sparse checkout), the files are recorded as _deleted_ instead.

The reason is that `git stash` tries to construct the tree reflecting
the worktree essentially by copying the index to a temporary one and
then updating the files from the worktree. Crucially, it calls `git
diff-index` to update also those files that are in the HEAD but have
been unstaged in the index.

However, when the temporary index is updated via `git update-index --add
--remove`, skip-worktree entries mark the files as deleted by mistake.

Let's use the newly-introduced `--ignore-skip-worktree-entries` option
of `git update-index` to prevent exactly this from happening.

Note that the regression test case deliberately avoids replicating the
scenario described above and instead tries to recreate just the symptom.

8dfb04ae96 update-index: optionally leave skip-worktree entries alone
While `git update-index` mostly ignores paths referring to index entries
whose skip-worktree bit is set, in b4d1690df1 (Teach Git to respect
skip-worktree bit (reading part), 2009-08-20), for reasons that are not
entirely obvious, the `--remove` option was made special: it _does_
remove index entries even if their skip-worktree bit is set.

Seeing as this behavior has been in place for a decade now, it does not
make sense to change it.

However, in preparation for fixing a bug in `git stash` where it
pretends that skip-worktree entries have actually been removed, we need
a mode where `git update-index` leaves all skip-worktree entries alone,
even if the `--remove` option was passed.

44ae131e38 builtin/blame.c: remove '--indent-heuristic' from usage string
The indent heuristic is our default diff heuristic since 33de716387
(diff: enable indent heuristic by default, 2017-05-08), but the usage
string of 'git blame' still mentions it as "experimental heuristic".

We could simply update the short help associated with the option, but
according to the comment above the option's declaration it was "only
included here to get included in the "-h" output".  That made sense
while the feature was still experimental and we wanted to give it more
exposure, but nowadays it's unnecessary.

So let's rather remove the '--indent-heuristic' option from 'git
blame's usage string.  Note that 'git blame' will still accept this
option, as it is parsed in parse_revision_opt().

Astute readers may notice that this patch removes a comment mentioning
"the following two options", but it only removes one option.  The
reason is that the comment is outdated: that other options was
'--compaction-heuristic', and it has already been removed in
3cde4e02ee (diff: retire "compaction" heuristics, 2016-12-23), but
that commit forgot to update this comment.

None of the callbacks actually care about having a "struct object";
they're happy with just the oid and type information. So let's give
ourselves more flexibility to avoid having a "struct object" by just
passing the broken-down fields.

Note that the callback already takes a "type" field for the fsck message

object type) to make the distinction explicit.

We don't actually care about having object structs; we only need to look
up decorations by oid. Let's accept this more limited form, which will
give our callers more flexibility.

Note that the decoration API we rely on uses object structs itself (even
though it only looks at their oids). We can solve this by switching to
a kh_oid_map (we could also use the hashmap oidmap, but it's more
awkward for the simple case of just storing a void pointer).

a59cfb3230 fsck: unify object-name code
Commit 90cf590f53 (fsck: optionally show more helpful info for broken
links, 2016-07-17) added a system for decorating objects with names. The
code is split across builtin/fsck.c (which gives the initial names) and
fsck.c (which adds to the names as it traverses the object graph). This
leads to some duplication, where both sites have near-identical
describe_object() functions (the difference being that the one in
builtin/fsck.c uses a circular array of buffers to allow multiple calls
in a single printf).

Let's provide a unified object_name API for fsck. That lets us drop the
duplication, as well as making the interface boundaries more clear
(which will let us refactor the implementation more in a future patch).

We'll leave describe_object() in builtin/fsck.c as a thin wrapper around
the new API, as it relies on a static global to make its many callers a
bit shorter.

We'll also convert the bare add_decoration() calls in builtin/fsck.c to
put_object_name(). This fixes two minor bugs:

  1. We leak many small strings. add_decoration() has a last-one-wins
     approach: it updates the decoration to the new string and returns
     the old one. But we ignore the return value, leaking the old
     string. This is quite common to trigger, since we look at reflogs:
     the tip of any ref will be described both by looking at the actual
     ref, as well as the latest reflog entry. So we'd always end up
     leaking one of those strings.

  2. The last-one-wins approach gives us lousy names. For instance, we
     first look at all of the refs, and then all of the reflogs. So
     rather than seeing "refs/heads/master", we're likely to overwrite
     it with "HEAD@{12345678}". We're generally better off using the
     first name we find.

     And indeed, the test in t1450 expects this ugly HEAD@{} name. After
     this patch, we've switched to using fsck_put_object_name()'s
     first-one-wins semantics, and we output the more human-friendly
     "refs/tags/julius" (and the test is updated accordingly).

c7aadccba0 fetch: delay fetch_if_missing=0 until after config
Suppose, from a repository that has ".gitmodules", we clone with
--filter=blob:none:

  git clone --filter=blob:none --no-checkout \
    https://kernel.googlesource.com/pub/scm/git/git

Then we fetch:

  git -C git fetch

This will cause a "unable to load config blob object", because the
fetch_config_from_gitmodules() invocation in cmd_fetch() will attempt to
load ".gitmodules" (which Git knows to exist because the client has the
tree of HEAD) while fetch_if_missing is set to 0.

fetch_if_missing is set to 0 too early - ".gitmodules" here should be
lazily fetched.  Git must set fetch_if_missing to 0 before the fetch
because as part of the fetch, packfile negotiation happens (and we do
not want to fetch any missing objects when checking existence of
objects), but we do not need to set it so early. Move the setting of
fetch_if_missing to the earliest possible point in cmd_fetch(), right
before any fetching happens.

680cba2c2b multi-pack-index: add [--[no-]progress] option.
Add the --[no-]progress option to git multi-pack-index.
Pass the MIDX_PROGRESS flag to the subcommand functions
when progress should be displayed by multi-pack-index.
The progress feature was added to 'verify' in 144d703
("multi-pack-index: report progress during 'verify'", 2018-09-13)
but some subcommands were not updated to display progress, and
the ability to opt-out was overlooked.

efbc3aee08 midx: add MIDX_PROGRESS flag
Add the MIDX_PROGRESS flag and update the
write|verify|expire|repack functions in midx.h
to accept a flags parameter.  The MIDX_PROGRESS
flag indicates whether the caller of the function
would like progress information to be displayed.
This patch only changes the method prototypes
and does not change the functionality. The
functionality change will be handled by a later patch.

86795774bb builtin/blame.c: constants into bit shift format
We are looking at bitfield constants, and elsewhere in the Git source
code, such cases are handled via bit shift operators rather than octal
numbers, which also makes it easier to spot holes in the range
(if, say, 1<<5 was missing, it is easier to spot it between 1<<4
and 1<<6 than it is to spot a missing 040 between a 020 and a 0100).

513f2b0bbd grep: make PCRE2 aware of custom allocator
94da9193a6 (grep: add support for PCRE v2, 2017-06-01) didn't include
a way to override the system allocator, and so it is incompatible with
custom allocators (e.g. nedmalloc). This problem became obvious when we
tried to plug a memory leak by `free()`ing a data structure allocated by
PCRE2, triggering a segfault in Windows (where we use nedmalloc by
default).

PCRE2 requires the use of a general context to override the allocator
and therefore, there is a lot more code needed than in PCRE1, including
a couple of wrapper functions.

Extend the grep API with a "destructor" that could be called to cleanup
any objects that were created and used globally.

Update `builtin/grep.c` to use that new API, but any other future users
should make sure to have matching `grep_init()`/`grep_destroy()` calls
if they are using the pattern matching functionality.

Move some of the logic that was before done per thread (in the workers)
into an earlier phase to avoid degrading performance, but as the use of
PCRE2 with custom allocators is better understood it is expected more of
its functions will be instructed to use the custom allocator as well as
was done in the original code[1] this work was based on.

d58deb9c4e notes: fix minimum number of parameters to "copy" subcommand
The builtin/notes.c::copy() function is prepared to handle either
one or two arguments given from the command line; when one argument
is given, to-obj defaults to HEAD.

bbb1b8a3 ("notes: check number of parameters to "git notes copy"",
2010-06-28) tried to make sure "git notes copy" (with *no* other
argument) does not dereference NULL by checking the number of
parameters, but it incorrectly insisted that we need two arguments,
instead of either one or two.  This disabled the defaulting to-obj
to HEAD.

Correct it.

5374a290aa fetch-pack: write fetched refs to .promisor
The specification of promisor packfiles (in partial-clone.txt) states
that the .promisor files that accompany packfiles do not matter (just
like .keep files), so whenever a packfile is fetched from the promisor
remote, Git has been writing empty .promisor files. But these files
could contain more useful information.

So instead of writing empty files, write the refs fetched to these
files. This makes it easier to debug issues with partial clones, as we
can identify what refs (and their associated hashes) were fetched at the
time the packfile was downloaded, and if necessary, compare those hashes
against what the promisor remote reports now.

This is implemented by teaching fetch-pack to write its own non-empty
.promisor file whenever it knows the name of the pack's lockfile. This
covers the case wherein the user runs "git fetch" with an internal
protocol or HTTP protocol v2 (fetch_refs_via_pack() in transport.c sets
lock_pack) and with HTTP protocol v0/v1 (fetch_git() in remote-curl.c
passes "--lock-pack" to "fetch-pack").
