cmd_reflog() invokes parse_options() with PARSE_OPT_KEEP_ARGV0, but it
doesn't account for the retained argv[0] before invoking
cmd_reflog_show() to handle the 'git reflog show' subcommand.
Consequently, cmd_reflog_show() always gets an 'argv' array starting
with elements argv[0]="reflog" and argv[1]="show".
Strip the name of the git command from the 'argv' array before passing
it to the function handling the 'show' subcommand.
There is no user-visible bug here, because cmd_reflog_show() doesn't
have any options or parameters of its own.

--refresh skip refreshing the index after reset
which explains what happens when the option is given in the negative

read "refresh the index after reset (default)" to hint that the user
can say "--no-refresh" to override the default, but listing the

Remove the 'reset.refresh' option, requiring that users explicitly specify
'--no-refresh' if they want to skip refreshing the index.
The 'reset.refresh' option was introduced in 101cee42dd (reset: introduce
--[no-]refresh option to --mixed, 2022-03-11) as a replacement for the
refresh-skipping behavior originally controlled by 'reset.quiet'.
Although 'reset.refresh=false' functionally served the same purpose as
'reset.quiet=true', it exposed [1] the fact that the existence of a global
"skip refresh" option could potentially cause problems for users. Allowing a
global config option to avoid refreshing the index forces scripts using 'git
reset --mixed' to defensively use '--refresh' if index refresh is expected;
if that option is missing, behavior of a script could vary from user-to-user
without explanation.
Furthermore, globally disabling index refresh in 'reset --mixed' was
initially devised as a passive performance improvement; since the
introduction of the option, other changes have been made to Git (e.g., the
sparse index) with a greater potential performance impact without
sacrificing index correctness. Therefore, we can more aggressively err on
the side of correctness and limit the cases of skipping index refresh to
only when a user specifies the '--no-refresh' option.

Remove the 'reset.quiet' config option, remove '--no-quiet' documentation in
'Documentation/git-reset.txt'. In 4c3abd0551 (reset: add new reset.quiet
config setting, 2018-10-23), 'reset.quiet' was introduced as a way to
globally change the default behavior of 'git reset --mixed' to skip index
refresh.
However, now that '--quiet' does not affect index refresh, 'reset.quiet'
would only serve to globally silence logging. This was not the original
intention of the config setting, and there's no precedent for such a setting
in other commands with a '--quiet' option, so it appears to be obsolete.
In addition to the options & its documentation, remove 'reset.quiet' from

"git rebase A B" where B is not a commit should behave as if the
HEAD got detached at B and then the detached HEAD got rebased on top
of A. A bug however overwrites the current branch to point at B,
when B is a descendant of A (i.e. the rebase ends up being a
fast-forward). See [1] for the original bug report.
The callstack from checkout_up_to_date() is the following:
cmd_rebase()
-> checkout_up_to_date()
-> reset_head()
-> update_refs()
-> update_ref()
When B is not a valid branch but an oid, rebase sets the head_name
of rebase_options to NULL. This value gets passed down this call
chain through the branch member of reset_head_opts also getting set
to NULL all the way to update_refs().
Then update_refs() checks ropts.branch to decide whether or not to switch
branches. If ropts.branch is NULL, it calls update_ref() to update HEAD.
At this point however, from rebase's point of view, we want a detached
HEAD. But, since checkout_up_to_date() does not set the RESET_HEAD_DETACH
flag, the update_ref() call will deference HEAD and update the branch its
pointing to. We want the HEAD detached at B instead.
Fix this bug by adding the RESET_HEAD_DETACH flag in
checkout_up_to_date if B is not a valid branch, so that once
reset_head() calls update_refs(), it calls update_ref() with
REF_NO_DEREF which updates HEAD directly intead of deferencing it
and updating the branch that HEAD points to.
Also add a test to ensure the correct behavior.

correctly, they may not fetch the necessary submodule commits, and
commands like "git checkout --recurse-submodules" might fail.
Teach "git fetch" to fetch cloned, changed submodules regardless of
whether they are populated. This is in addition to the current behavior
of fetching populated submodules (which is always attempted regardless
of what was fetched in the superproject, or even if nothing was fetched
in the superproject).
A submodule may be encountered multiple times (via the list of
populated submodules or via the list of changed submodules). When this
happens, "git fetch" only reads the 'populated copy' and ignores the

When format is passed into --batch, --batch-check, --batch-command,

is set and the expand_format() gets called.
We can save on these cycles by hardcoding how to print the

format is passed. There is no need for the fully expanded format with
the default. Since batch_object_write() happens on every object provided

Add the options '-q' and '--refresh' to the 'git reset' executed in
'reset_head()', and '--refresh' to the 'git reset -q' executed in
'do_push_stash(...)'.
'stash' is implemented such that git commands invoked as part of it (e.g.,
'clean', 'read-tree', 'reset', etc.) have their informational output
silenced. However, the 'reset' in 'reset_head()' is *not* called with '-q',
leading to the potential for a misleading printout from 'git stash apply
--index' if the stash included a removed file:
Unstaged changes after reset: D <deleted file>
Not only is this confusing in its own right (since, after the reset, 'git
stash' execution would stage the deletion in the index), it would be printed
even when the stash was applied with the '-q' option. As a result, the
messaging is removed entirely by calling 'git status' with '-q'.
Additionally, because the default behavior of 'git reset -q' is to skip
refreshing the index, but later operations in 'git stash' subcommands expect
a non-stale index, enable '--refresh' as well.

Add a new --[no-]refresh option that is intended to explicitly determine
whether a mixed reset should end in an index refresh.
Starting at 9ac8125d1a (reset: don't compute unstaged changes after reset
when --quiet, 2018-10-23), using the '--quiet' option results in skipping
the call to 'refresh_index(...)' at the end of a mixed reset with the goal
of improving performance. However, by coupling behavior that modifies the
index with the option that silences logs, there is no way for users to have
one without the other (i.e., silenced logs with a refreshed index) without
incurring the overhead of a separate call to 'git update-index --refresh'.
Furthermore, there is minimal user-facing documentation indicating that
--quiet skips the index refresh, potentially leading to unexpected issues
executing commands after 'git reset --quiet' that do not themselves refresh
the index (e.g., internals of 'git stash', 'git read-tree').
To mitigate these issues, '--[no-]refresh' and 'reset.refresh' are
introduced to provide a dedicated mechanism for refreshing the index. When
either is set, '--quiet' and 'reset.quiet' revert to controlling only
whether logs are silenced and do not affect index refresh.

doing; more generally, it updates the properties of index entries that are
affected by outside-of-index state, e.g. CE_UPTODATE, which is affected by
the file contents on-disk. This distinction is relevant to operations that
read the index but do not refresh first - e.g., 'git read-tree' - where a

If a commit in a sequence of linear history has a non-monotonically
increasing commit timestamp, git name-rev might not properly name the
commit.
This occurs because name-rev uses a heuristic of the commit date to
avoid searching down tags which lead to commits that are older than the
named commit. This is intended to avoid work on larger repositories.
This heuristic impacts git name-rev, and by extension git describe
--contains which is built on top of name-rev.
Further more, if --all or --annotate-stdin is used, the heuristic is not
enabled because the full history has to be analyzed anyways. This
results in some confusion if a user sees that --annotate-stdin works but
a normal name-rev does not.
If the repository has a commit graph, we can use the generation numbers
instead of using the commit dates. This is essentially the same check
except that generation numbers make it exact, where the commit date
heuristic could be incorrect due to clock errors.
Since we're extending the notion of cutoff to more than one variable,
create a series of functions for setting and checking the cutoff. This
avoids duplication and moves access of the global cutoff and
generation_cutoff to as few functions as possible.
Add several test cases including a test that covers the new commitGraph
behavior, as well as tests for --all and --annotate-stdin with and

This commit introduces the infrastructure for the core.fsync
configuration knob. The repository components we want to sync
are identified by flags so that we can turn on or off syncing
for specific components.
If core.fsyncObjectFiles is set and the core.fsync configuration
also includes FSYNC_COMPONENT_LOOSE_OBJECT, we will fsync any
loose objects. This picks the strictest data integrity behavior
if core.fsync and core.fsyncObjectFiles are set to conflicting values.
This change introduces the currently unused fsync_component
helper, which will be used by a later patch that adds fsyncing to
the refs backend.
Actual configuration and documentation of the fsync components
list are in other patches in the series to separate review of
the underlying mechanism from the policy of how it's configured.

Updates to how command line options to "git help" are handled.
* ab/help-fixes:
help: don't print "\n" before single-section output
help: add --no-[external-commands|aliases] for use with --all
help: error if [-a|-g|-c] and [-i|-m|-w] are combined
help: correct usage & behavior of "git help --all"
help: note the option name on option incompatibility
help.c: split up list_all_cmds_help() function
help tests: test "git" and "git help [-a|-g] spacing
help.c: use puts() instead of printf{,_ln}() for consistency
help doc: add missing "]" to "[-a|--all]"
"git cat-file" learns "--batch-command" mode, which is a more
flexible interface than the existing "--batch" or "--batch-check"
modes, to allow different kinds of inquiries made.
* jc/cat-file-batch-commands:
cat-file: add --batch-command mode
cat-file: add remove_timestamp helper
cat-file: introduce batch_mode enum to replace print_contents
cat-file: rename cmdmode to transform_mode
