Copy detection cannot work when comparing the index to the working tree
because Git ignores files that it is not explicitly told to track. It
should work in the other direction, though, i.e. for a reverse diff of
the deletion of a copy from the index.
d1f2d7e8ca (Make run_diff_index() use unpack_trees(), not read_tree(),
2008-01-19) broke it with a seemingly stray change to run_diff_files().
We didn't notice because there's no test for that. But even if we had
one, it might have gone unnoticed because the breakage only happens
with index preloading, which requires at least 1000 entries (more than
most test repos have) and is racy because it runs in parallel with the
actual command.
Fix copy detection by queuing up-to-date and skip-worktree entries using
diff_same().
While at it, use diff_same() also for queuing unchanged files not
flagged as up-to-date, i.e. clean submodules and entries where
preloading was not done at all or not quickly enough. It uses less
memory than diff_change() and doesn't unnecessarily set the diff flag
has_changes.
Add two tests to cover running both without and with preloading. The
first one passes reliably with the original code. The second one
enables preloading and thus is racy. It has a good chance to pass even
without the fix, but fails within seconds when running the test script
with --stress. With the fix it runs fine for several minutes, until
my patience runs out.

These config values were added in the original Scalar contribution,
d0feac4e8c (scalar: 'register' sets recommended config and starts
maintenance, 2021-12-03), but were never fully checked for validity in
the upstream Git project. At the time, Scalar was only intended for the
contrib/ directory so did not have as rigorous of an investigation.
Each config option has its own justification for removal:
* core.preloadIndex: This value is true by default, now. Removing this
causes some changes required to the tests that checked this config
value. Use gui.gcwarning=false instead.
* core.fscache: This config does not exist in the core Git project, but
is instead a config option for a Git for Windows feature.
* core.multiPackIndex: This config value is now enabled by default, so
does not need to be called out specifically. It was originally
included to make sure the background maintenance that created
multi-pack-indexes would result in the expected performance
improvements.
* credential.validate: This option is not something specific to Git but
instead an older version of Git Credential Manager for Windows. That
software was replaced several years ago by the cross-platform Git
Credential Manger so this option is no longer needed to help users who
were on that older software.
* pack.useSparse=true: This value is now Git's default as of de3a864114
(config: set pack.useSparse=true by default, 2020-03-20) so we don't
need it set by Scalar.

The index.skipHash config option has been set to 'false' by Scalar since
4933152cbb (scalar: enable path-walk during push via config, 2025-05-16)
but that commit message is trying to communicate the exact opposite:
that the 'true' value is what we want instead. This means that we've
been disabling this performance benefit for Scalar repos
unintentionally.
Fix this issue before we add justification for the config options set in
this list.
Oddly, enabling index.skipHash causes a test issue during 'test_commit'
in one of the Scalar tests when GIT_TEST_SPLIT_INDEX is enabled (as
caught by the linux-test-vars build). I'm fixing the test by disabling
the environment variable, but the issue should be resolved in a series
focused on the split index.

A repo may have config options set by 'scalar clone' or 'scalar
register' and then updated by 'scalar reconfigure'. It can be helpful to
point out which of those options were set by the latest scalar
recommendations.
Add "# set by scalar" to the end of each config option to assist users
in identifying why these config options were set in their repo. Use a new
helper method to simplify the two callsites.

Fix a regression introduced with batched updates in 0e358de64a (fetch:
use batched reference updates, 2025-05-19) when fetching references. In
the `do_fetch()` function, we jump to cleanup if committing the
transaction fails, regardless of whether using batched or atomic
updates. This skips three subsequent operations:
- Update 'FETCH_HEAD' as part of `commit_fetch_head()`.
- Add upstream tracking information via `set_upstream()`.
- Setting remote 'HEAD' values when `do_set_head` is true.
For atomic updates, this is expected behavior. For batched updates,
we want to continue with these operations even if some refs fail to
update.
Skipping `commit_fetch_head()` isn't actually a regression because
'FETCH_HEAD' is already updated via `append_fetch_head()` when not
using '--atomic'. However, we add a test to validate this behavior.
Skipping the other two operations (upstream tracking and remote HEAD)
is a regression. Fix this by only jumping to cleanup when using
'--atomic', allowing batched updates to continue with post-fetch
operations. Add tests to prevent future regressions.

The commit 0e358de64a (fetch: use batched reference updates, 2025-05-19)
updated the 'git-fetch(1)' command to use batched updates. This batches
updates to gain performance improvements. When fetching references, each
update is added to the transaction. Finally, when committing, individual
updates are allowed to fail with reason, while the transaction itself
succeeds.
One scenario which was missed here, was fetching tags. When fetching
conflicting tags, the `fetch_and_consume_refs()` function returns '1',
which skipped committing the transaction and directly jumped to the
cleanup section. This mean that no updates were applied. This also
extends to backfilling tags which is done when fetching specific
refspecs which contains tags in their history.
Fix this by committing the transaction when we have an error code and
not using an atomic transaction. This ensures other references are
applied even when some updates fail.
The cleanup section is reached with `retcode` set in several scenarios:
- `truncate_fetch_head()`, `open_fetch_head()` and `prune_refs()` set
`retcode` before the transaction is created, so no commit is
attempted.
- `fetch_and_consume_refs()` and `backfill_tags()` are the primary
cases this fix targets, both setting a positive `retcode` to
trigger the committing of the transaction.
This simplifies error handling and ensures future modifications to
`do_fetch()` don't need special handling for batched updates.
Add tests to check for this regression. While here, add a missing
cleanup from previous test.

When pushing to a set of remotes using a nickname for the group, the
client initializes the connection to each remote, talks to the
remote and reads and parses capabilities line, and holds the
capabilities in a file-scope static variable server_capabilities_v1.
There are a few other such file-scope static variables, and these
connections cannot be parallelized until they are refactored to a
structure that keeps track of active connections.
Which is *not* the theme of this patch ;-)
For a single connection, the server_capabilities_v1 variable is
initialized to NULL (at the program initialization), populated when
we talk to the other side, used to look up capabilities of the other
side possibly multiple times, and the memory is held by the variable
until program exit, without leaking. When talking to multiple remotes,
however, the server capabilities from the second connection overwrites
without freeing the one from the first connection, which leaks.

In a sparse checkout, a user might want to run `last-modified` on a
directory outside the worktree.
And even in non-sparse checkouts, a user might need to run that command
on a directory that does not exist in the worktree.
These use cases should be supported via the `--` separator between
revision and file arguments, which is even advertised in the
documentation. This patch fixes a tiny bug that prevents that from
working.

8fbd903e (branch: advise about ref syntax rules, 2024-03-05) added
an advice about checking git-check-ref-format(1) for the ref syntax
rules. The advice uses man(1). But git(1) is a multi-platform tool and
man(1) may not be available on some platforms. It might also be slightly
jarring to see a suggestion for running a command which is not from
the Git suite.
Let’s instead use git-help(1) in order to stay inside the land of
git(1). This also means that `help.format` (for `man`, `html` or other
formats) will be used if set.
Also change to using single quotes (') to quote the command since that
is more conventional.
While here let’s also update the test to use `{SQ}`, which is more
readable and easier to edit.

This test starts a SOCKS server in Perl in the background and then kills
it after the tests are done. However, when using zsh (in sh mode) in
the tests, the start_socks function hangs until the background process
is killed.
Note that this does not reproduce in a simple shell script, so there is
likely some interaction between job handling, our heavy use of eval in
the test framework, and possibly other complexities of our test
framework. What is clear, however, is that switching from a compound
statement to a subshell fixes the problem entirely and the test passes
with no problem, so do that.

In this comparison, we want to know whether the number of lines is
greater than 1. Our test_line_count function passes the first argument
as the comparison operator to test, so what we want is a numerical
comparison, not a string comparison. While this does not produce a
functional problem now, it could very well if we expected two or more
items, in which case the value "10" would not match when it should.
Furthermore, the "<" and ">" comparisons are new in POSIX 1003.1-2024
and we don't want to require such a new version of POSIX since many
popular and supported operating systems were released before that
version of POSIX was released.
Finally, zsh's builtin test operator does not like the greater-than sign
in "test", since it is only supported in the double-bracket extension.
This has been reported and will be addressed in a future version, but
since our code is also technically incorrect, as well as not very
compatible, let's fix it by using a numeric comparison.

Tools like `git filter-repo`[1] use `git fast-export` and
`git fast-import` to rewrite repository history. When rewriting
history using one such tool though, commit signatures might become
invalid because the commits they sign changed due to the changes
in the repository history made by the tool between the fast-export
and the fast-import steps.
Note that as far as signature handling goes:
* Since fast-export doesn't know what changes filter-repo may make
to the stream, it can't know whether the signatures will still be
valid.
* Since filter-repo doesn't know what history canonicalizations
fast-export performed (and it performs a few), it can't know whether
the signatures will still be valid.
* Therefore, fast-import is the only process in the pipeline that
can know whether a specified signature remains valid.
Having invalid signatures in a rewritten repository could be
confusing, so users rewritting history might prefer to simply
discard signatures that are invalid at the fast-import step.
For example a common use case is to rewrite only "recent" history.
While specifying commit ranges corresponding to "recent" commits
could work, users worry about getting it wrong and want to just
automatically rewrite everything, expecting older commit signatures
to be untouched.
To let them do that, let's add a new 'strip-if-invalid' mode to the
`--signed-commits=<mode>` option of `git fast-import`.
It would be interesting for the `--signed-tags=<mode>` option to
have this mode too, but we leave that for a future improvement.
It might also be possible for `git fast-export` to have such a mode
in its `--signed-commits=<mode>` and `--signed-tags=<mode>`
options, but the use cases for it are much less clear, so we also
leave that for possible future improvements.
For now let's just die() if 'strip-if-invalid' is passed to these
options where it hasn't been implemented yet.

though, we don't even have to set it up even once: all we need is to set
up its hash algorithm, because we still depend on some subsystems that

When asked to perform object consistency checks via the `--fsck-objects`
flag we verify that each object part of the pack is valid. In general,
this check can even be performed outside of a Git repository: we don't
need an initialized object database as we simply read the object from
the packfile directly.
But there's one exception: a subset of the object checks may be deferred
to a later point in time. For now, this only concerns ".gitmodules" and
".gitattributes" files: whenever we see a tree referencing these files
we queue them for a deferred check. This is done because we need to do
some extra checks for those files to ensure that they are well-formed,
and these checks need to be done regardless of whether the corresponding
blobs are part of the packfile or not.
This works inside a repository, but unfortunately the logic leads to a
segfault when running outside of one. This is because we eventually call
`odb_read_object()`, which will crash because the object database has
not been initialized.
There's multiple options here:
- We could in theory create a purely in-memory database with only a
packfile store that contains the single packfile. We don't really
have the infrastructure for this yet though, and it would end up
being quite hacky.
- We could refuse to perform consistency checks outside of a
repository. But most of the checks work alright, so this would be a
regression.
- We can skip the finalizing consistency checks when running outside
of a repository. This is not as invasive as skipping all checks,
but it's not great to randomly skip a subset of tests, either.
None of these options really feel perfect. The first one would be the
obvious choice if easily possible.
There's another option though: instead of skipping the final object
checks, we can die if there are any queued object checks. With this
change we now die exactly if and only if we would have previously
segfaulted. Like this we ensure that objects that _may_ fail the
consistency checks won't be silently skipped, and at the same time we
give users a much better error message.
Refactor the code accordingly and add a test that would have triggered
the segfault. Note that we also move down the logic to add the packfile
to the store. There is no point doing this any earlier than right before
we execute `fsck_finish()`, and it ensures that the logic to set up and
perform the consistency check is self-contained.

"git submodule add" tries to find if a submodule with the same name
already exists at a different path, by looking up an entry in the
.gitmodules file. If the entry in the file is incomplete, e.g.,
when the submodule.<name>.something variable is defined but there is
no definition of submodule.<name>.path variable, it accesses the
missing .path member of the submodule structure and triggers a
segfault.
A brief audit was done to make sure that the code does not assume
members other than those that are absolutely certain to exist: a
submodule obtained by submodule_from_name() should have .name
member, while a submodule obtained by submodule_from_path() should
also have .path as well as .name member, and we cannot assume
anything else. Luckily, the module_add() codepath was the only
problematic one. It is fairly recent code that comes from 1fa06ced
(submodule: prevent overwriting .gitmodules on path reuse,
2025-07-24).
A helper used by update_submodule() seems to assume that its call to
submodule_from_path() always yields a submodule object without a
failure, which seems to rely on the caller making sure it is the
case. Leave an assert() with a NEEDSWORK comment there for future
developers to make sure the assumption actually holds.

Earlier we added support for a value spelled as ":(optional)path"
for configuration variables whose values are of type "path", with
the documented semantics "if the path is missing, behave as if such
a variable definition is not even there."
This has worked OK for code paths that reads configuration files and
stores the configured value as a string, where NULL in such a string
is treated as if the setting is not there, left as the default.
However, there are other code paths that do not _ignore_ such NULL
values and misbehave. "git config get --path" is one of them.
When git_config_pathname() helper function finds that the value of
the variable is an optional path *and* the path is missing, it
leaves the destination pointer intact (which usually is left to
NULL) and returns 0 to signal a success. format_config() helper
however assumed that the destination pointer always gets a string,
which no longer is the case, and segfaulted.
Make sure that git_config_pathname() clears the destination pointer
in such a case, and teach format_config() to react to the condition
by returning 1 (which is different from 0 that is a normal success
and negative that is an error) to its callers. Adjust the callers
to react to this new return value that tells them to pretend as if
they did not even see this partcular <key, value> pair.

The "git repo structure" subcommand tried to align its output but
mixed up byte count and display column width, which has been
corrected.
* jx/repo-struct-utf8width-fix:
builtin/repo: fix table alignment for UTF-8 characters
t/unit-tests: add UTF-8 width tests for CJK chars

"git replay" (experimental) learned to perform ref updates itself
in a transaction by default, instead of emitting where each refs
should point at and leaving the actual update to another command.
* sa/replay-atomic-ref-updates:
replay: add replay.refAction config option
replay: make atomic ref updates the default behavior
replay: use die_for_incompatible_opt2() for option validation

Adding a repository that uses a different hash function is a no-no,
but "git submodule add" did nt prevent it, which has been corrected.
* bc/submodule-force-same-hash:
read-cache: drop submodule check from add_to_cache()
object-file: disallow adding submodules of different hash algo

The code to expand attribute macros has been rewritten to avoid
recursion to avoid running out of stack space in an uncontrolled
way.

"git maintenance" command learned "is-needed" subcommand to tell if
it is necessary to perform various maintenance tasks.
* kn/maintenance-is-needed:
maintenance: add 'is-needed' subcommand
maintenance: add checking logic in `pack_refs_condition()`
refs: add a `optimize_required` field to `struct ref_storage_be`
reftable/stack: add function to check if optimization is required
reftable/stack: return stack segments directly

As "git diff --quiet" only cares about the existence of any
changes, disable rename/copy detection to skip more expensive
processing whose result will be discarded anyway.
* rs/diff-quiet-no-rename:
diff: disable rename detection with --quiet

Code clean-up.
* kn/refs-optim-cleanup:
t/pack-refs-tests: move the 'test_done' to callees
refs: rename 'pack_refs_opts' to 'refs_optimize_opts'
refs: move to using the '.optimize' functions

Some ref backend storage can hold not just the object name of an
annotated tag, but the object name of the object the tag points at.
The code to handle this information has been streamlined.
* ps/ref-peeled-tags:
t7004: do not chdir around in the main process
ref-filter: fix stale parsed objects
ref-filter: parse objects on demand
ref-filter: detect broken tags when dereferencing them
refs: don't store peeled object IDs for invalid tags
object: add flag to `peel_object()` to verify object type
refs: drop infrastructure to peel via iterators
refs: drop `current_ref_iter` hack
builtin/show-ref: convert to use `reference_get_peeled_oid()`
ref-filter: propagate peeled object ID
upload-pack: convert to use `reference_get_peeled_oid()`
refs: expose peeled object ID via the iterator
refs: refactor reference status flags
refs: fully reset `struct ref_iterator::ref` on iteration
refs: introduce `.ref` field for the base iterator
refs: introduce wrapper struct for `each_ref_fn`

Add a new flag `--all` to git-repo-info for requesting values for all
the available keys. By using this flag, the user can retrieve all the
values instead of searching what are the desired keys for what they
wants.

If a worktree path contains newlines or other control characters
it messes up the output of "git worktree list". Fix this by using
quote_path() to display the worktree path. The output of "git worktree
list" is designed for human consumption, scripts should be using the
"--porcelain" option so this change should not break them.

The output of "git worktree list" displays a table containing the
worktree path, HEAD OID and branch name for each worktree. The code
aligns the columns by measuring the visual width of the worktree path
when it is printed. Unfortunately it fails to use the visual width
when calculating the width of the column so, if any of the paths
contain a multibyte character, we can end up with excess padding
between columns. The simplest fix would be to replace strlen() with
utf8_strwidth() in measure_widths(). However that leaves us measuring
the visual width twice and the byte length once. By caching the visual
width and printing the padding separately to the worktree path, we only
need to calculate the visual width once and do not need the byte length
at all. The visual widths are stored in an arrays of structs rather
than an array of ints as the next commit will add more struct members.
Even if there are no multibyte characters in any of the paths we still
print an extra space between the path and the object id as the field
width is calculated as one plus the length of the path and we print an
explicit space as well. This is fixed by not printing the extra space.
The tests are updated to include multibyte characters in one of the
worktree paths and to check the spacing of the columns.
