ceaf037f61 stash: strip "refs/heads/" with skip_prefix
When generating a message for a stash, "git stash" only records the
part of the branch name to the right of the last "/". e.g. if HEAD is at
"foo/bar/baz", "git stash" generates a message prefixed with "WIP on
baz:" instead of "WIP on foo/bar/baz:".

Fix this by using skip_prefix() to skip "refs/heads/" instead of looking
for the last instance of "/".

e77aa336f1 ("ls-files: optionally recurse into submodules", 2016-10-10)
taught ls-files the --recurse-submodules argument, but only in a limited

because there was no repo_find_unique_abbrev(), which was only
introduced in 8bb95572b0 ("sha1-name.c: add
repo_find_unique_abbrev_r()", 2019-04-16). This function is needed for
using --recurse-submodules with --stage.

Do the same for the "--all" option that I did for "--guides" in

As with other changes made in 62f035aee3 (Merge branch

behavior, but in practice it's just a bug fix. We were ignoring this
before, but by erroring we can simplify our documentation and
synopsis, as well as avoid user confusion as they wonder what the
difference between e.g. "git help --all" and "git help --all status"
is (there wasn't any difference).

8dd7c4739b sparse-checkout: reject arguments in cone-mode that look like patterns
In sparse-checkout add/set under cone mode, the arguments passed are
supposed to be directories rather than gitignore-style patterns.
However, given the amount of effort spent in the manual discussing
patterns, it is easy for users to assume they need to pass patterns such
as
   /foo/*
or
   !/bar/*/
or perhaps they really do ignore the directory rule and specify a
random gitignore-style pattern like
   *.c

To help catch such mistakes, throw an error if any of the positional
arguments:
  * starts with any of '/!'
  * contains any of '*?[]'

Inform users they can pass --skip-checks if they have a directory that
really does have such special characters in its name.  (We exclude '\'
because of sparse-checkout's special handling of backslashes; see
the MINGW test in t1091.46.)

4ce504360b sparse-checkout: error or warn when given individual files
The set and add subcommands accept multiple positional arguments.
The meaning of these arguments differs slightly in the two modes:

Cone mode only accepts directories.  If given a file, it would
previously treat it as a directory, causing not just the file itself to
be included but all sibling files as well -- likely against users'
expectations.  Throw an error if the specified path is a file in the
index.  Provide a --skip-checks argument to allow users to override
(e.g. for the case when the given path IS a directory on another
branch).

Non-cone mode accepts general gitignore patterns.  There are many
reasons to avoid this mode, but one possible reason to use it instead of
cone mode: to be able to select individual files within a directory.
However, if a file is passed to set/add in non-cone mode, you won't be
selecting a single file, you'll be selecting a file with the same name
in any directory.  Thus users will likely want to prefix any paths they
specify with a leading '/' character; warn users if the patterns they
specify exactly name a file because it means they are likely missing
such a leading slash.

bb8b5e9a90 sparse-checkout: pay attention to prefix for {set, add}
In cone mode, non-option arguments to set & add are clearly paths, and
as such, we should pay attention to prefix.

In non-cone mode, it is not clear that folks intend to provide paths
since the inputs are gitignore-style patterns.  Paying attention to
prefix would prevent folks from doing things like
   git sparse-checkout add /.gitattributes
   git sparse-checkout add '/toplevel-dir/*'
In fact, the former will result in
   fatal: '/.gitattributes' is outside repository...
while the later will result in
   fatal: Invalid path '/toplevel-dir': No such file or directory
despite the fact that both are valid gitignore-style patterns that would
select real files if added to the sparse-checkout file.  This might lead
people to just use the path without the leading slash, potentially
resulting in them grabbing files with the same name throughout the
directory hierarchy contrary to their expectations.  See also [1] and
[2].  Adding prefix seems to just be fraught with error; so for now
simply throw an error in non-cone mode when sparse-checkout set/add are
run from a subdirectory.

d526b4dbe1 sparse-checkout: correctly set non-cone mode when expected
commit f2e3a218e8 ("sparse-checkout: enable `set` to initialize
sparse-checkout mode", 2021-12-14) made the `set` command able to
initialize sparse-checkout mode, but it also had to function when
sparse-checkout mode was already setup and the user just wanted to
change the sparsity paths.  So, if the user passed --cone or --no-cone,
then we should override the current setting, but if they didn't pass
either, we should use whatever the current cone mode setting is.

Unfortunately, there was a small error in the logic in that it would not
set the in-memory cone mode value (core_sparse_checkout_one) when
--no-cone was specified, but since it did set the config setting on
disk, any subsequent git invocation would correctly get non-cone mode.
As such, the error did not previously matter.  However, a subsequent
commit will add some logic that depends on core_sparse_checkout_cone
being set to the correct mode, so make sure it is set consistently with
the config values we will be writing to disk.

f748012e01 sparse-checkout: correct reapply's handling of options
Commit 4e256731d6 ("sparse-checkout: enable reapply to take
--[no-]{cone,sparse-index}", 2021-12-14) made it so that reapply could
take additional options but added no tests.  Tests would have shown that
the feature doesn't work because the initial values are set AFTER
parsing the command line options instead of before.  Add a test and set
the initial value at the appropriate time.

440c705ea6 cat-file: add --batch-command mode
Add a new flag --batch-command that accepts commands and arguments
from stdin, similar to git-update-ref --stdin.

At GitLab, we use a pair of long running cat-file processes when
accessing object content. One for iterating over object metadata with
--batch-check, and the other to grab object contents with --batch.

However, if we had --batch-command, we wouldn't need to keep both
processes around, and instead just have one --batch-command process
where we can flip between getting object info, and getting object
contents. Since we have a pair of cat-file processes per repository,
this means we can get rid of roughly half of long lived git cat-file
processes. Given there are many repositories being accessed at any given
time, this can lead to huge savings.

git cat-file --batch-command

will enter an interactive command mode whereby the user can enter in
commands and their arguments that get queued in memory:

<command1> [arg1] [arg2] LF
<command2> [arg1] [arg2] LF

When --buffer mode is used, commands will be queued in memory until a
flush command is issued that execute them:

flush LF

The reason for a flush command is that when a consumer process (A)
talks to a git cat-file process (B) and interactively writes to and
reads from it in --buffer mode, (A) needs to be able to control when
the buffer is flushed to stdout.

Currently, from (A)'s perspective, the only way is to either

1. kill (B)'s process
2. send an invalid object to stdin.

1. is not ideal from a performance perspective as it will require
spawning a new cat-file process each time, and 2. is hacky and not a
good long term solution.

With this mechanism of queueing up commands and letting (A) issue a
flush command, process (A) can control when the buffer is flushed and
can guarantee it will receive all of the output when in --buffer mode.
--batch-command also will not allow (B) to flush to stdout until a flush
is received.

This patch adds the basic structure for adding command which can be
extended in the future to add more commands. It also adds the following
two commands (on top of the flush command):

contents <object> LF
info <object> LF

The contents command takes an <object> argument and prints out the object
contents.

The info command takes an <object> argument and prints out the object
metadata.

These can be used in the following way with --buffer:

info <object> LF
contents <object> LF
contents <object> LF
info <object> LF
flush LF
info <object> LF
flush LF

When used without --buffer:

info <object> LF
contents <object> LF
contents <object> LF
info <object> LF
info <object> LF

ac4e58cab9 cat-file: introduce batch_mode enum to replace print_contents
A future patch introduces a new --batch-command flag. Including --batch
and --batch-check, we will have a total of three batch modes. print_contents
is the only boolean on the batch_options sturct used to distinguish
between the different modes. This makes the code harder to read.

To reduce potential confusion, replace print_contents with an enum to
help readability and clarity.
