"git sparse-checkout (add|set) --[no-]cone --end-of-options" did
not handle "--end-of-options" correctly after a recent update.

"git sparse-checkout set" added default patterns even when the
patterns are being fed from the standard input, which has been
corrected.
* jc/sparse-checkout-set-default-fix:
sparse-checkout: use default patterns for 'set' only !stdin
|
|
"git sparse-checkout set ---no-cone" uses default patterns when none
is given from the command line, but it should do so ONLY when
--stdin is not being used. Right now, add_patterns_from_input()
called when reading from the standard input is sloppy and does not
check if there are extra command line parameters that the command
will silently ignore, but that will change soon and not setting this
unnecessary and unused default patterns start to matter when it gets
fixed.

93851746 (parse-options: decouple "--end-of-options" and "--",
2023-12-06) updated the world order to make callers of parse-options
that set PARSE_OPT_KEEP_UNKNOWN_OPT responsible for deciding what to
do with "--end-of-options" they may see after parse_options() returns.
This made a previous bug in sparse-checkout more visible; namely,
that
git sparse-checkout [add|set] --[no-]cone --end-of-options ...
would simply treat "--end-of-options" as one of the paths to include in
the sparse-checkout. But this was already problematic before; namely,
git sparse-checkout [add|set| --[no-]cone --sikp-checks ...
would not give an error on the mis-typed "--skip-checks" but instead
simply treat "--sikp-checks" as a path or pattern to include in the
sparse-checkout, which is highly unfriendly.
This behavior began when the command was converted to parse-options in
7bffca95ea (sparse-checkout: add '--stdin' option to set subcommand,
2019-11-21). Back then it was just called KEEP_UNKNOWN. Later it was
renamed to KEEP_UNKNOWN_OPT in 99d86d60e5 (parse-options:
PARSE_OPT_KEEP_UNKNOWN only applies to --options, 2022-08-19) to clarify
that it was only about dashed options; we always keep non-option
arguments. Looking at that original patch, both Peff and I think that
the author was simply confused about the mis-named option, and really
just wanted to keep the non-option arguments. We never should have used
the flag all along (and the other cases were cargo-culted within the
file).
Remove the erroneous PARSE_OPT_KEEP_UNKNOWN_OPT flag now to fix this
bug. Note that this does mean that anyone who might have been using
git sparse-checkout [add|set] [--[no-]cone] --foo --bar
to request paths or patterns '--foo' and '--bar' will now have to use
git sparse-checkout [add|set] [--[no-]cone] -- --foo --bar
That makes sparse-checkout more consistent with other git commands,
provides users much friendlier error messages and behavior, and is
consistent with the all-caps warning in git-sparse-checkout.txt that
this command "is experimental...its behavior...will likely change". :-)

Each of these were checked with

to ensure that removing the direct inclusion of the header actually
resulted in that header no longer being included at all (i.e. that
no other header pulled it in transitively).

Since this header showed up in some places besides just #include
statements, update/clean-up/remove those other places as well.
Note that compat/fsmonitor/fsm-path-utils-darwin.c previously got
away with violating the rule that all files must start with an include
of git-compat-util.h (or a short-list of alternate headers that happen
to include it first). This change exposed the violation and caused it
to stop building correctly; fix it by having it include
git-compat-util.h first, as per policy.

There exists no direct way to interrogate git about which paths are
matched by a given set of sparsity rules. It is possible to get this
information from git, but it includes checking out the commit that
contains the paths, applying the sparse checkout patterns and then using
something like 'git ls-files -t' to check if the skip worktree bit is
set. This works in some case, but there are cases where it is awkward or
infeasible to generate a checkout for this purpose.
Exposing the pattern matching of sparse checkout enables more tooling to
be built and avoids a situation where tools that want to reason about
sparse checkouts start containing parallel implementation of the rules.
To accommodate this, add a 'check-rules' subcommand to the
'sparse-checkout' builtin along the lines of the 'git check-ignore' and
'git check-attr' commands. The new command accepts a list of paths on
stdin and outputs just the ones the match the sparse checkout.
To allow for use in a bare repository and to allow for interrogating
about other patterns than the current ones, include a '--rules-file'
option which allows the caller to explicitly pass sparse checkout rules
in the format accepted by 'sparse-checkout set --stdin'.
To allow for reuse of the handling of input patterns for the
'--rules-file' flag, modify 'add_patterns_from_input()' to be able to
read from a 'FILE' instead of just stdin.
To allow for reuse of the logic which decides whether or not rules
should be interpreted as cone-mode patterns, split that part out of
'update_modes()' such that can be called without modifying the config.
An alternative could have been to create a new 'check-sparsity' command.
However, placing it under 'sparse-checkout' allows for a) more easily
re-using the sparse checkout pattern matching and cone/non-code mode
handling, and b) keeps the documentation for the command next to the
experimental warning and the cone-mode discussion.

entry in the 'commands' array of 'git.c'.
To avoid that this changes any behaviour, add calls to

tests that verify that 'sparse-checkout <cmd>' still fail with a clear
error message telling the user that the command needs a work tree.

Dozens of files made use of gettext functions, without explicitly
including gettext.h. This made it more difficult to find which files
could remove a dependence on cache.h. Make C files explicitly include

However, while compat/fsmonitor/fsm-ipc-darwin.c should also gain an

Commit 2f6b1eb794 ("cache API: add a "INDEX_STATE_INIT" macro/function,
add release_index()", 2023-01-12) mistakenly added some initialization
of a member of unpack_trees_options that was intended to be
internal-only. This initialization should be done within
update_sparsity() instead.
Note that while o->result is mostly meant for unpack_trees() and
update_sparsity() mostly operates without o->result,
check_ok_to_remove() does consult it so we need to ensure it is properly
initialized.

struct unpack_trees_options has the following field and comment:
struct pattern_list *pl; /* for internal use */
Despite the internal-use comment, commit e091228e17 ("sparse-checkout:
update working directory in-process", 2019-11-21) starting setting this
field from an external caller. At the time, the only way around that
would have been to modify unpack_trees() to take an extra pattern_list
argument, and there's a lot of callers of that function. However, when
we split update_sparsity() off as a separate function, with
sparse-checkout being the sole caller, the need to update other callers
went away. Fix this API problem by adding a pattern_list argument to
update_sparsity() and stop setting the internal o.pl field directly.

When the "repo" member was added to "the_index" in [1] the
repo_read_index() was made to populate it, but the unpopulated
"the_index" variable didn't get the same treatment.
Let's do that in initialize_the_repository() when we set it up, and
likewise for all of the current callers initialized an empty "struct
index_state".
This simplifies code that needs to deal with "the_index" or a custom
"struct index_state", we no longer need to second-guess this part of
the "index_state" deep in the stack. A recent example of such
second-guessing is the "istate->repo ? istate->repo : the_repository"
code in [2]. We can now simply use "istate->repo".
We're doing this by making use of the INDEX_STATE_INIT() macro (and
corresponding function) added in [3], which now have mandatory "repo"
arguments.
Because we now call index_state_init() in repository.c's
initialize_the_repository() we don't need to handle the case where we
have a "repo->index" whose "repo" member doesn't match the "repo"
we're setting up, i.e. the "Complete the double-reference" code in
repo_read_index() being altered here. That logic was originally added
in [1], and was working around the lack of what we now have in
initialize_the_repository().
For "fsmonitor-settings.c" we can remove the initialization of a NULL
"r" argument to "the_repository". This was added back in [4], and was
needed at the time for callers that would pass us the "r" from an
"istate->repo". Before this change such a change to
"fsmonitor-settings.c" would segfault all over the test suite (e.g. in
t0002-gitfile.sh).
This change has wider eventual implications for
"fsmonitor-settings.c". The reason the other lazy loading behavior in
it is required (starting with "if (!r->settings.fsmonitor) ..." is
because of the previously passed "r" being "NULL".
I have other local changes on top of this which move its configuration
reading to "prepare_repo_settings()" in "repo-settings.c", as we could
now start to rely on it being called for our "r". But let's leave all
of that for now, and narrowly remove this particular part of the
lazy-loading.

Hopefully in some not so distant future, we'll get advantages from always
initializing the "repo" member of the "struct index_state". To make
that easier let's introduce an initialization macro & function.
The various ad-hoc initialization of the structure can then be changed
over to it, and we can remove the various "0" assignments in
discard_index() in favor of calling index_state_init() at the end.
While not strictly necessary, let's also change the CALLOC_ARRAY() of
various "struct index_state *" to use an ALLOC_ARRAY() followed by
index_state_init() instead.
We're then adding the release_index() function and converting some
callers (including some of these allocations) over to it if they
either won't need to use their "struct index_state" again, or are just
about to call index_state_init().

It's arguably more correct to say "[<option>...]" than either of these
forms, but the vast majority of our documentation uses the
"[<options>]" form to indicate an arbitrary number of options, let's
do the same in these cases, which were the odd ones out.
In the case of "mv" and "sparse-checkout" let's add the missing "[]"
to indicate that these are optional.
In the case of "t/helper/test-proc-receive.c" there is no *.txt

Recent commits such as bf0a6b65fc (builtin/multi-pack-index.c: let
parse-options parse subcommands, 2022-08-19) converted a few functions
to match our usual argc/argv/prefix conventions, but the prefix argument
remains unused.
However, there is a good use for it: they should pass it to their own
parse_options() functions, where it may be used to adjust the value of
any filename options. In all but one of these functions, there's no
behavior change, since they don't use OPT_FILENAME. But this is an
actual fix for one option, which you can see by modifying the test suite
like so:
diff --git a/t/t5326-multi-pack-bitmaps.sh b/t/t5326-multi-pack-bitmaps.sh
index 4fe57414c1..d0974d4371 100755

I'd emphasize that this wasn't broken by bf0a6b65fc; it has been broken
all along, because the sub-function never got to see the prefix. It is
that commit which is actually enabling us to fix it (and which also
brought attention to the problem because it triggers -Wunused-parameter!)
The other functions changed here don't use OPT_FILENAME at all. In their
cases this isn't fixing anything visible, but it's following the usual
pattern and future-proofing them against somebody adding new options and
being surprised.
I didn't include a test for the one visible case above. We don't
generally test routine parse-options behavior for individual options.
The challenge here was finding the problem, and now that this has been
done, it's not likely to regress. Likewise, we could apply the patch
above to cover it "for free" but it makes reading the rest of the test
unnecessarily complicated.

'git sparse-checkout' parses its subcommands with a couple of if
statements. parse-options has just learned to parse subcommands, so
let's use that facility instead, with the benefits of shorter code,
handling missing or unknown subcommands, and listing subcommands for
Bash completion.
Note that some of the functions implementing each subcommand only
accept the 'argc' and '**argv' parameters, so add a (unused) '*prefix'
parameter to make them match the type expected by parse-options, and
thus avoid casting function pointers.

When modifying the sparse-checkout definition, the sparse-checkout
builtin calls update_sparsity() to modify the SKIP_WORKTREE bits of all
cache entries in the index. Before, we needed the index to be fully
expanded in order to ensure we had the full list of files necessary that
match the new patterns.
Insert a call to reset_sparse_directories() that expands sparse
directories that are within the new pattern list, but only far enough
that every necessary file path now exists as a cache entry. The
remaining logic within update_sparsity() will modify the SKIP_WORKTREE
bits appropriately.
This allows us to disable command_requires_full_index within the
sparse-checkout builtin. Add tests that demonstrate that we are not
expanding to a full index unnecessarily.
We can see the improved performance in the p2000 test script:
Test HEAD~1 HEAD
------------------------------------------------------------------------
2000.24: git ... (sparse-v3) 2.14(1.55+0.58) 1.57(1.03+0.53) -26.6%
2000.25: git ... (sparse-v4) 2.20(1.62+0.57) 1.58(0.98+0.59) -28.2%
These reductions of 26-28% are small compared to most examples, but the
time is dominated by writing a new copy of the base repository to the
worktree and then deleting it again. The fact that the previous index
expansion was such a large portion of the time is telling how important
it is to complete this sparse index integration.

A future change will present a temporary, in-memory mode where the index
can both contain sparse directory entries but also not be completely
collapsed to the smallest possible sparse directories. This will be
necessary for modifying the sparse-checkout definition while using a
sparse index.
For now, convert the single-bit member 'sparse_index' in 'struct
index_state' to be a an 'enum sparse_index_mode' with three modes:
* INDEX_EXPANDED (0): No sparse directories exist. This is always the
case for repositories that do not use cone-mode sparse-checkout.
* INDEX_COLLAPSED: Sparse directories may exist. Files outside the
sparse-checkout cone are reduced to sparse directory entries whenever
possible.
* INDEX_PARTIALLY_SPARSE: Sparse directories may exist. Some file
entries outside the sparse-checkout cone may exist. Running
convert_to_sparse() may further reduce those files to sparse directory
entries.
The main reason to store this extra information is to allow
convert_to_sparse() to short-circuit when the index is already in
INDEX_EXPANDED mode but to actually do the necessary work when in
INDEX_PARTIALLY_SPARSE mode.
The INDEX_PARTIALLY_SPARSE mode will be used in an upcoming change.

Fix a memory leak in code added in 6c622f9f0bb (commit-graph: write
commit-graph chains, 2019-06-18). We needed to free the "lock_name" if
we encounter errors, and the "graph_name" after we'd run unlink() on
it.
For the case of write_commit_graph_file() refactoring the code to free
the "lock_name" after we were done using the "struct lock_file lk"
would have made the control flow more complex. Luckily we can free the
"lock_file" right after the hold_lock_file_for_update() call, if it
makes use of "path" at all it'll have copied its contents to a "struct
strbuf" of its own.
While I'm at it let's fix code added in fb10ca5b543 (sparse-checkout:
write using lockfile, 2019-11-21) in write_patterns_and_update() to
avoid the same complexity that I thought I needed when I wrote the
initial fix for write_commit_graph_file(). We can free the
"sparse_filename" right after calling hold_lock_file_for_update(), we
don't need to wait until we're exiting the function to do so.

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.)

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.

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.

`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.
