If two 'git sparse-checkout set' subcommands are launched at the
same time, the behavior can be unexpected as they compete to write
the sparse-checkout file and update the working directory.
Take a lockfile around the writes to the sparse-checkout file. In
addition, acquire this lock around the working directory update
to avoid two commands updating the working directory in different
ways.

The 'git sparse-checkout disable' subcommand returns a user to a
full working directory. The old process for doing this required
updating the sparse-checkout file with the "/*" pattern and then
updating the working directory with core.sparseCheckout enabled.
Finally, the sparse-checkout file could be removed and the config
setting disabled.
However, it is valuable to keep a user's sparse-checkout file
intact so they can re-enable the sparse-checkout they previously
used with 'git sparse-checkout init'. This is now possible with
the in-process mechanism for updating the working directory.

The sparse-checkout builtin used 'git read-tree -mu HEAD' to update the
skip-worktree bits in the index and to update the working directory.
This extra process is overly complex, and prone to failure. It also
requires that we write our changes to the sparse-checkout file before
trying to update the index.
Remove this extra process call by creating a direct call to
unpack_trees() in the same way 'git read-tree -mu HEAD' does. In
addition, provide an in-memory list of patterns so we can avoid
reading from the sparse-checkout file. This allows us to test a
proposed change to the file before writing to it.
An earlier version of this patch included a bug when the 'set' command
failed due to the "Sparse checkout leaves no entry on working directory"
error. It would not rollback the index.lock file, so the replay of the
old sparse-checkout specification would fail. A test in t1091 now
covers that scenario.

If a user provides folders A/ and A/B/ for inclusion in a cone-mode
sparse-checkout file, the parsing logic will notice that A/ appears
both as a "parent" type pattern and as a "recursive" type pattern.
This is unexpected and hence will complain via a warning and revert
to the old logic for checking sparse-checkout patterns.
Prevent this from happening accidentally by sanitizing the folders
for this type of inclusion in the 'git sparse-checkout' builtin.
This happens in two ways:
1. Do not include any parent patterns that also appear as recursive
patterns.
2. Do not include any recursive patterns deeper than other recursive
patterns.
In order to minimize duplicate code for scanning parents, create
hashmap_contains_parent() method. It takes a strbuf buffer to
avoid reallocating a buffer when calling in a tight loop.

When someone wants to clone a large repository, but plans to work
using a sparse-checkout file, they either need to do a full
checkout first and then reduce the patterns they included, or
clone with --no-checkout, set up their patterns, and then run
a checkout manually. This requires knowing a lot about the repo
shape and how sparse-checkout works.
Add a new '--sparse' option to 'git clone' that initializes the
sparse-checkout file to include the following patterns:
/*
!/*/
These patterns include every file in the root directory, but
no directories. This allows a repo to include files like a
README or a bootstrapping script to grow enlistments from that
point.
During the 'git sparse-checkout init' call, we must first look
to see if HEAD is valid, since 'git clone' does not have a valid
HEAD at the point where it initializes the sparse-checkout. The
following checkout within the clone command will create the HEAD
ref and update the working directory correctly.

The sparse-checkout feature is mostly hidden to users, as its
only documentation is supplementary information in the docs for
'git read-tree'. In addition, users need to know how to edit the
.git/info/sparse-checkout file with the right patterns, then run
the appropriate 'git read-tree -mu HEAD' command. Keeping the
working directory in sync with the sparse-checkout file requires
care.
Begin an effort to make the sparse-checkout feature a porcelain
feature by creating a new 'git sparse-checkout' builtin. This
builtin will be the preferred mechanism for manipulating the
sparse-checkout file and syncing the working directory.
The documentation provided is adapted from the "git read-tree"
documentation with a few edits for clarity in the new context.

'git unpack-objects' shows a progress line only counting the number of
unpacked objects, so if some of the received objects are unusually
large, then that progress might appear to be frozen while processing
such a larger object. I just stared at a seemingly stuck progress
line for over half a minute, while 'git fetch' was busy receiving a
pack with only a couple of objects (i.e. fewer than
'fetch.unpackLimit'), with one of them being over 80MB.
Display throughput in 'git unpack-objects' progress line, so we show
that something is going on even when receiving and processing a large
object.
Counting the consumed bytes is far away from the place that
counts objects and displays progress, and to pass around the 'struct
progress' instance we would have to modify the signature of five
functions and 14 of their callsites: this is just too much churn, so
let's rather make it file-scope static.

Ever since it was introduced in 7cceca5ccc (Add 'git rev-parse

treated a missing working tree as a quiet success: it neither prints a
toplevel path, but nor does it report any kind of error.
While a caller could distinguish this case by looking for an empty
response, the behavior is rather confusing. We're better off complaining
that there is no working tree, as other internal commands would do in
similar cases (e.g., "git status" or any builtin with NEED_WORK_TREE set
would just die()). So let's do the same here.

Unlike previous conversions to C, where we started with a built-in
helper, we start this conversion by adding an interception in the
`run_add_interactive()` function when the new opt-in
`add.interactive.useBuiltin` config knob is turned on (or the
corresponding environment variable `GIT_TEST_ADD_I_USE_BUILTIN`), and
calling the new internal API function `run_add_i()` that is implemented
directly in libgit.a.
At this point, the built-in version of `git add -i` only states that it
cannot do anything yet. In subsequent patches/patch series, the
`run_add_i()` function will gain more and more functionality, until it
is feature complete. The whole arc of the conversion can be found in the
PRs #170-175 at https://github.com/gitgitgadget/git.
The "--helper approach" can unfortunately not be used here: on Windows
we face the very specific problem that a `system()` call in
Perl seems to close `stdin` in the parent process when the spawned
process consumes even one character from `stdin`. Which prevents us from
implementing the main loop in C and still trying to hand off to the Perl
script.
The very real downside of the approach we have to take here is that the
test suite won't pass with `GIT_TEST_ADD_I_USE_BUILTIN=true` until the
conversion is complete (the `--helper` approach would have let it pass,
even at each of the incremental conversion steps).

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.

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

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).

The first line in 'git commit-graph's usage string indicates that this
command can be invoked without specifying a subcommand. However, this
is not the case:
$ git commit-graph
usage: git commit-graph [--object-dir <objdir>]
or: git commit-graph read [--object-dir <objdir>]
[...]
$ echo $?
129
Remove this line from the usage string.
The synopsis in the manpage doesn't contain this line.

Add an option to print the object format used for input, output, or
storage. This allows shell scripts to discover the hash algorithm in
use.
Since the transition plan allows for multiple input algorithms, document
that we may provide multiple results for input, and the format that the
results may take. While we don't support this now, documenting it early
means that script authors can future-proof their scripts for when we do.

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.

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.

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.

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).
