"checkout --merge -- path" and "update-index --unresolve path" did
not resurrect conflicted state that was resolved to remove path,
but now they do.
* jc/unresolve-removal:
checkout: allow "checkout -m path" to unmerge removed paths
checkout/restore: add basic tests for --merge
checkout/restore: refuse unmerging paths unless checking out of the index
update-index: remove stale fallback code for "--unresolve"
update-index: use unmerge_index_entry() to support removal
resolve-undo: allow resurrecting conflicted state that resolved to deletion
update-index: do not read HEAD and MERGE_HEAD unconditionally

"git update-index" learns "--show-index-version" to inspect
the index format version used by the on-disk index file.
* jc/update-index-show-index-version:
test-tool: retire "index-version"
update-index: add --show-index-version
update-index doc: v4 is OK with JGit and libgit2
|

"git update-index --index-version N" is used to set the index format
version to a specific version, but there was no way to query the
current version used in the on-disk index file.
Teach the command a new "--show-index-version" option, and also
teach the "--index-version N" option to report what the version was
when run with the "--verbose" option.

The previous commit argued that parse-options callbacks should try to
use opt->value rather than touching globals directly. In some cases,
however, that's awkward to do. Some callbacks touch multiple variables,
or may even just call into an abstracted function that does so.
In some of these cases we _could_ convert them by stuffing the multiple
variables into a single struct and passing the struct pointer through
opt->value. But that may make other parts of the code less readable,
as the struct relationship has to be mentioned everywhere.
Let's just accept that these cases are special and leave them as-is. But
we do need to mark their "opt" parameters to satisfy -Wunused-parameter.

"git checkout -m -- path" uses the unmerge_marked_index() API, whose
implementation is incapable of unresolving a path that was resolved
as removed. Extend the unmerge_index() API function so that we can
mark the ce_flags member of the cache entries we add to the index as
unmerged, and replace use of unmerge_marked_index() with it.
Now, together with its unmerge_index_entry_at() helper function,
unmerge_marked_index() function is no longer called by anybody, and
can safely be removed.
This makes two known test failures in t2070 and t7201 to succeed.

The "update-index --unresolve" is a relatively old feature that was
introduced in Git v1.4.1 (June 2006), which predates the
resolve-undo extension introduced in Git v1.7.0 (February 2010).
The original code that was limited only to work during a merge (and
not during a rebase or a cherry-pick) has been kept as the fallback
codepath to be used as a transition measure.
By now, for more than 10 years we have stored resolve-undo extension
in the index file, and the fallback code way outlived its usefulness.
Remove it, together with two file-scope static global variables.
One of these variables is still used by surviving function, but it
does not have to be a global at all, so move it to local to that
function.

"update-index --unresolve" uses the unmerge_index_entry_at() that
assumes that the path to be unresolved must be in the index, which
makes it impossible to unresolve a path that was resolved as removal.
Rewrite unresolve_one() to use the unmerge_index_entry() to support
unresolving such a path.
Existing tests for "update-index --unresolve" forgot to check one
thing that tests for "checkout --merge -- paths" tested, which is to
make sure that resolve-undo record that has already been used to
recreate higher-stage index entries is removed. Add new invocations
of "ls-files --resolve-undo" after running "update-index --unresolve"
to make sure that unresolving with update-index does remove the used
resolve-undo records.

When "update-index --unresolve $path" cannot find the resolve-undo
record for the path the user requested to unresolve, it stuffs the
blobs from HEAD and MERGE_HEAD to stage #2 and stage #3 as a
fallback. For this reason, the operation does not even start unless
both "HEAD" and "MERGE_HEAD" exist.
This is suboptimal in a few ways:
* It does not recreate stage #1. Even though it is a correct
design decision not to do so (because it is impossible to
recreate in general cases, without knowing how we got there,
including what merge strategy was used), it is much less useful
not to have that information in the index.
* It limits the "unresolve" operation only during a conflicted "git
merge" and nothing else. Other operations like "rebase",
"cherry-pick", and "switch -m" may result in conflicts, and the
user may want to unresolve the conflict that they incorrectly
resolved in order to redo the resolution, but the fallback would
not kick in.
* Most importantly, the entire "unresolve" operation is disabled
after a conflicted merge is committed and MERGE_HEAD is removed,
even though the index has perfectly usable resolve-undo records.
By lazily reading the HEAD and MERGE_HEAD only when we need to go to
the fallback codepath, we will allow cases where resolve-undo
records are available (which is 100% of the time, unless the user is
reading from an index file created by Git more than 10 years ago) to
proceed even after a conflicted merge was committed, during other
mergy operations that do not use MERGE_HEAD, or after the result of
such mergy operations has been committed.

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

hash.h depends upon and includes repository.h, due to the definition and
use of the_hash_algo (defined as the_repository->hash_algo). However,
most headers trying to include hash.h are only interested in the layout
of the structs like object_id. Move the parts of hash.h that do not
depend upon repository.h into a new file hash-ll.h (the "low level"
parts of hash.h), and adjust other files to use this new header where
the convenience inline functions aren't needed.
This allows hash.h and object.h to be fairly small, minimal headers. It
also exposes a lot of hidden dependencies on both path.h (which was
brought in by repository.h) and repository.h (which was previously
implicitly brought in by object.h), so also adjust other files to be
more explicit about what they depend upon.

could remove a dependence on cache.h. Make C files explicitly include

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

Apply the rule added in [1] to change "cache_name_pos" to
"index_name_pos", which allows us to get rid of another
"USE_THE_INDEX_COMPATIBILITY_MACROS" macro.
The replacement of "USE_THE_INDEX_COMPATIBILITY_MACROS" here with
"USE_THE_INDEX_VARIABLE" is a manual change on top, now that these
files only use "&the_index", and don't need any compatibility
macros (or functions).

Apply "index-compatibility.pending.cocci" rule to "builtin/*", but
exclude those where we conflict with in-flight changes.
As a result some of them end up using only "the_index", so let's have
them use the more narrow "USE_THE_INDEX_VARIABLE" rather than
"USE_THE_INDEX_COMPATIBILITY_MACROS".
Manual changes not made by coccinelle, that were squashed in:
* Whitespace-wrap argument lists for repo_hold_locked_index(),
repo_read_index_preload() and repo_refresh_and_write_index(), in cases
where the line became too long after the transformation.
* Change "refresh_cache()" to "refresh_index()" in a comment in

Mostly apply the part of "index-compatibility.pending.cocci" that
renames the global variables like "active_nr", which are a shorthand
to referencing (in that case) a struct member as "the_index.cache_nr".
In doing so move more of "index-compatibility.pending.cocci" to

In the case of "active_nr" we'd have a textual conflict with

Since 4aab5b46f44 (Make read-cache.c "the_index" free., 2007-04-01)
we've been undergoing a slow migration away from these macros, but
haven't made much progress since f8adbec9fea (cache.h: flip
NO_THE_INDEX_COMPATIBILITY_MACROS switch, 2019-01-24).
Let's move forward a bit by changing the users of those macros that
are rare enough that we can convert them in one go, and then remove
the compatibility shim.
The only manual change to the C code here is to "cache.h", the rest is
all the result of applying the new "index-compatibility.cocci".
Even though it's a one-off, let's keep the coccinelle rules for
now. We'll extend them in subsequent commits, and this will help
anything that's in-flight or out-of-tree to migrate.

The parse-options callback for --again soaks up all remaining options by
manipulating the parse_opt_ctx's argc and argv fields. Even though it
has to look at both, the actual parsing happens via the do_reupdate()
helper, which only looks at the argv half (by passing it along to
parse_pathspec). So that helper doesn't need to see argc at all.
Note that the helper does look at "argv + 1" without confirming that
argc is greater than 0. We know this is correct because it is skipping
past the actual "--again" string, which will always be present. However,
to make what's going on more obvious, let's move that "+1" into the
caller, which has the matching "-1" when fixing up the ctx's argc/argv.

The update-index functionality is used internally by 'git stash push' to
setup the internal stashed commit.
This change enables odb-transactions for update-index infrastructure to
speed up adding new objects to the object database by leveraging the
batch fsync functionality.
There is some risk with this change, since under batch fsync, the object
files will be in a tmp-objdir until update-index is complete, so callers
using the --stdin option will not see them until update-index is done.
This risk is mitigated by flushing the ODB transaction prior to
reporting any verbose output so that objects will be visible to callers
that are synchronizing with update-index by snooping its output.

Move fsmonitor config settings to a new and opaque
`struct fsmonitor_settings` structure. Add a lazily-loaded pointer
to this into `struct repo_settings`
Create an `enum fsmonitor_mode` type in `struct fsmonitor_settings` to
represent the state of fsmonitor. This lets us represent which, if
any, fsmonitor provider (hook or IPC) is enabled.
Create `fsm_settings__get_*()` getters to lazily look up fsmonitor-
related config settings.
Get rid of the `core_fsmonitor` global variable. Move the code to
lookup the existing `core.fsmonitor` config value into the fsmonitor
settings.
Create a hook pathname variable in `struct fsmonitor-settings` and
only set it when in hook mode.
Extend the definition of `core.fsmonitor` to be either a boolean
or a hook pathname. When true, the builtin FSMonitor is used.
When false or unset, no FSMonitor (neither builtin nor hook) is
used.
The existing `core_fsmonitor` global variable was used to store the
pathname to the fsmonitor hook *and* it was used as a boolean to see
if fsmonitor was enabled. This dual usage and global visibility leads
to confusion when we add the IPC-based provider. So lets hide the
details in fsmonitor-settings.c and let it decide which provider to
use in the case of multiple settings. This avoids cluttering up
repo-settings.c with these private details.
A future commit in builtin-fsmonitor series will add the ability to
disqualify worktrees for various reasons, such as being mounted from a
remote volume, where fsmonitor should not be started. Having the
config settings hidden in fsmonitor-settings.c allows such worktree
restrictions to override the config values used.

Replace unconditional index expansion in 'do_reupdate()' with one scoped to
only where a full index is needed. A full index is only required in
'do_reupdate()' when a sparse directory in the index differs from HEAD; in
that case, the index is expanded and the operation restarted.
Because the index should only be expanded if a sparse directory is modified,
add a test ensuring the index is not expanded when differences only exist
within the sparse cone.

Enable use of the sparse index with `update-index`. Most variations of
`update-index` work without explicitly expanding the index or making any
other updates in or outside of `update-index.c`.
The one usage requiring additional changes is `--cacheinfo`; if a file
inside a sparse directory was specified, the index would not be expanded
until after the cache tree is invalidated, leading to a mismatch between the
index and cache tree. This scenario is handled by rearranging
`add_index_entry_with_check`, allowing `index_name_stage_pos` to expand the
index *before* attempting to invalidate the relevant cache tree path,
avoiding cache tree/index corruption.

'git update-index --refresh' and '--really-refresh' should force writing
of the index file if racy timestamps have been encountered, as
'git status' already does [1].
Note that calling 'git update-index --refresh' still does not guarantee
that there will be no more racy timestamps afterwards (the same holds
true for 'git status'):
- calling 'git update-index --refresh' immediately after touching and
adding a file may still leave racy timestamps if all three operations
occur within the racy-tolerance (usually 1 second unless USE_NSEC has
been defined)
- calling 'git update-index --refresh' for timestamps which are set into
the future will leave them racy
To guarantee that such racy timestamps will be resolved would require to
wait until the system clock has passed beyond these timestamps and only
then write the index file. Especially for future timestamps, this does
not seem feasible because of possibly long delays/hangs.

In the codebase, there are many options which use OPTION_CALLBACK in a
plain ol' struct definition. However, we have the OPT_CALLBACK and
OPT_CALLBACK_F macros which are meant to abstract these plain struct
definitions away. These macros are useful as they semantically signal to
developers that these are just normal callback option with nothing fancy
happening.
Replace plain struct definitions of OPTION_CALLBACK with OPT_CALLBACK or
OPT_CALLBACK_F where applicable. The heavy lifting was done using the
following (disgusting) shell script:
#!/bin/sh
do_replacement () {
tr '\n' '\r' |

tr '\r' '\n'
}
for f in $(git ls-files \*.c)
do
do_replacement <"$f" >"$f.tmp"
mv "$f.tmp" "$f"

The result was manually inspected and then reformatted to match the
style of the surrounding code. Finally, using
`git grep OPTION_CALLBACK \*.c`, leftover results which were not handled
by the script were manually transformed.

"git stash save" in a working tree that is sparsely checked out

* js/update-index-ignore-removal-for-skip-worktree:
stash: handle staged changes in skip-worktree files correctly
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 b4d1690df11 (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.

The core.untrackedCache config setting is slightly complicated,
so clarify its use and centralize its parsing into the repo
settings.
The default value is "keep" (returned as -1), which persists the
untracked cache if it exists.
If the value is set as "false" (returned as 0), then remove the
untracked cache if it exists.
If the value is set as "true" (returned as 1), then write the
untracked cache and persist it.
Instead of relying on magic values of -1, 0, and 1, split these
options into an enum. This allows the use of "-1" as a
default value. After parsing the config options, if the value is
unset we can initialize it to UNTRACKED_CACHE_KEEP.

"git merge-recursive" backend recently learned a new heuristics to

moved. As this is inherently less robust heuristics than the one
based on the content similarity of the file itself (rather than

leave the renamed paths in higher/conflicted stages in the index so
that the user can examine and confirm the result.

merge-recursive: rename merge_options argument from 'o' to 'opt'
Use 'unsigned short' for mode, like diff_filespec does

A new hook "post-index-change" is called when the on-disk index
file changes, which can help e.g. a virtualized working tree
implementation.

read-cache: add post-index-change hook

struct diff_filespec defines mode to be an 'unsigned short'. Several
other places in the API which we'd like to interact with using a
diff_filespec used a plain unsigned (or unsigned int). This caused
problems when taking addresses, so switch to unsigned short.

The prefix is always a NUL-terminated string, and we just end up passing
it along to parse_pathspec() anyway (which does not even take a length).

The diff machinery, one of the oldest parts of the system, which
long predates the parse-options API, uses fairly long and complex
handcrafted option parser. This is being rewritten to use the
parse-options API.
* nd/diff-parseopt:
diff.c: convert --raw
diff.c: convert -W|--[no-]function-context
diff.c: convert -U|--unified
diff.c: convert -u|-p|--patch
diff.c: prepare to use parse_options() for parsing
diff.h: avoid bit fields in struct diff_flags
diff.h: keep forward struct declarations sorted
parse-options: allow ll_callback with OPTION_CALLBACK
parse-options: avoid magic return codes
parse-options: stop abusing 'callback' for lowlevel callbacks
parse-options: add OPT_BITOP()
parse-options: disable option abbreviation with PARSE_OPT_KEEP_UNKNOWN
parse-options: add one-shot mode
parse-options.h: remove extern on function prototypes

Add a post-index-change hook that is invoked after the index is written in
do_write_locked_index().
This hook is meant primarily for notification, and cannot affect
the outcome of git commands that trigger the index write.
The hook is passed a flag to indicate whether the working directory was
updated or not and a flag indicating if a skip-worktree bit could have
changed. These flags enable the hook to optimize its response to the
index change notification.

OPTION_CALLBACK is much simpler/safer to use, but parse_opt_cb does
not allow access to parse_opt_ctx_t, which sometimes is useful
(e.g. to obtain the prefix).
Extending parse_opt_cb to take parse_opt_cb could result in a lot of
changes. Instead let's just allow ll_callback to be used with
OPTION_CALLBACK. The user will have to be careful, not to change
anything in ctx, or return wrong result code. But that's the price for
ll_callback.
