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.

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.

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.

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

There is value in renaming cmdmode in any case. cmdmode refers to how

for the flag.

This is another simple change with a long explanation...
merge-recursive and merge-ort are both based on the same recursive idea:
if there is more than one merge base, merge the merge bases (which may
require first merging the merge bases of the merges bases, etc.). The
depth of the inner merge is recorded via a variable called "call_depth",
which we'll bring up again later. Naturally, the inner merges
themselves can have conflicts and various messages generated about those
files.
merge-recursive immediately prints to stdout as it goes, at the risk of
printing multiple conflict notices for the same path separated far apart
from each other with many intervenining conflict notices for other paths
between them. And this is true even if there are no inner merges
involved. An example of this was given in [1] and apparently caused
some confusion:
CONFLICT (rename/add): Rename A->B in HEAD. B added in otherbranch
...dozens of conflicts for OTHER paths...
CONFLICT (content): Merge conflicts in B
In contrast, merge-ort collects messages and stores them by path so that
it can print them grouped by path. Thus, the same case handled by
merge-ort would have output of the form:
CONFLICT (rename/add): Rename A->B in HEAD. B added in otherbranch
CONFLICT (content): Merge conflicts in B
...dozens of conflicts for OTHER paths...
This is generally helpful, but does make a separate bug more
problematic. In particular, while merge-recursive might report the
following for a recursive merge:
Auto-merging dir.c
Auto-merging midx.c
CONFLICT (content): Merge conflict in midx.c
Auto-merging diff.c
Auto-merging dir.c
CONFLICT (content): Merge conflict in dir.c
merge-ort would instead report:
Auto-merging diff.c
Auto-merging dir.c
Auto-merging dir.c
CONFLICT (content): Merge conflict in dir.c
Auto-merging midx.c
CONFLICT (content): Merge conflict in midx.c
The fact that messages for the same file are together is probably
helpful in general, but with the indentation missing for the inner
merge it unfortunately serves to confuse. This probably would lead
users to wonder:
* Why is Git reporting that "dir.c" is being merged twice?
* If midx.c has conflicts, why do I not see any when I open up the
file and why are no conflicts shown in the index?
Fix this output confusion by changing the output to clearly
differentiate the messages for outer merges from the ones for inner
merges, changing the above output from merge-ort to:
Auto-merging diff.c
From inner merge: Auto-merging dir.c
Auto-merging dir.c
CONFLICT (content): Merge conflict in dir.c
From inner merge: Auto-merging midx.c
From inner merge: CONFLICT (content): Merge conflict in midx.c
(Note: the number of spaces after the 'From inner merge:' is
2*call_depth).
One other thing to note here, that I didn't notice until typing up this
commit message, is that merge-recursive does not print any messages from
the inner merges by default; the extra verbosity has to be requested.
merge-ort currently has no verbosity controls and always prints these.
We may also want to change that, but for now, just make the output
clearer with these extra markings and indentation.

The GIT_FORCE_UNTRACKED_CACHE environment variable writes the untracked
cache more frequently than the core.untrackedCache config variable. This
is due to how read_directory() handles the creation of an untracked
cache.
Before this change, Git would not create the untracked cache extension
for an index that did not already have one. Users would need to run a
command such as 'git update-index --untracked-cache' before the index
would actually contain an untracked cache.
In particular, users noticed that the untracked cache would not appear
even with core.untrackedCache=true. Some users reported setting
GIT_FORCE_UNTRACKED_CACHE=1 in their engineering system environment to
ensure the untracked cache would be created.
The decision to not write the untracked cache without an environment
variable tracks back to fc9ecbeb9 (dir.c: don't flag the index as dirty
for changes to the untracked cache, 2018-02-05). The motivation of that
change is that writing the index is expensive, and if the untracked
cache is the only thing that needs to be written, then it is more
expensive than the benefit of the cache. However, this also means that
the untracked cache never gets populated, so the user who enabled it via
config does not actually get the extension until running 'git
update-index --untracked-cache' manually or using the environment
variable.
We have had a version of this change in the microsoft/git fork for a few
major releases now. It has been working well to get users into a good
state. Yes, that first index write is slow, but the remaining index
writes are much faster than they would be without this change.

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().
