If there were only two kinds, e.g. "mixed" vs "separate", it might

"git reset --separate" and vice-versa, but because we have many

"git show-branch --no-topo-order" behaved exactly the same way as
"git show-branch --topo-order" did, which was nonsense. This was
because we choose between topo- and date- by setting a variable to
either REV_SORT_IN_GRAPH_ORDER or REV_SORT_BY_COMMIT_DATE with
OPT_SET_INT() and REV_SORT_IN_GRAPH_ORDER happens to be 0. The
OPT_SET_INT() macro assigns 0 to the target variable in respose to
the negated form of its option.
"--no-date-order" by luck behaves identically to "--topo-order"
exactly for the same reason, and it sort-of makes sense right now,
but the "sort-of makes sense" will quickly break down once we add a
third way to sort. Not-A may be B when there are only two choices
between A and B, but once your choices become among A, B, and C,
not-A does not mean B.
Just mark these two ordering options to reject negation, and add a
test, which was missing. "git show-branch --no-reflog" is also
unnegatable, so throw in a test for that while we are at it.

"git show-branch --no-sparse" behaved exactly the same way as "git
show-branch --sparse", which did not make any sense. This was
because it used a variable "dense" initialized to 1 by default to
give "non sparse" behaviour, and OPT_SET_INT() to set the varilable
to 0 in response to the "--sparse" option. Unfortunately,
OPT_SET_INT() sets 0 to the given variable when the option is
negated.
Flip the polarity of the variable "dense" by renaming it to "sparse"
and initializing it to 0, and have OPT_SET_INT() set the variable to
1 when "--sparse" is given. This way, "--no-sparse" would set 0 to
the variable and would give us the "dense" behaviour.

The reflog-expire command has been unimplemented since it was added in

We could mark these as UNUSED to silence the warning. But let's just
drop the function. It has no callers in the test suite and is not doing
anything useful, beyond perhaps reminding us that it's something we
_could_ be testing.
But since the bulk of the work in adding such tests would be the shell

this is not even a useful step in that direction. Somebody who wants to
do that work later can easily add this function back.

In a narrow but common case, the user is the only author of a branch and
doesn't mind overwriting the corresponding branch on the remote. This
workflow is especially common on GitHub, GitLab, and Gerrit, which keep
a permanent record of every version of a branch that is pushed while a
pull request is open for that branch. On those platforms, force-pushing
is encouraged and is analogous to emailing a new version of a patchset.
When giving advice about divergent branches, tell the user about
`git pull`, but don't unconditionally instruct the user to do it. A less
prescriptive message will help prevent users from thinking that they are
required to create an integrated history instead of simply replacing the
previous history. Likewise, don't imply that `git pull` is only for

In 73320e49ad (builtin/repack.c: only collect fully-formed packs,
2023-06-07), we switched the check for which packs to collect by
starting at the .idx files and looking for matching .pack files. This
avoids trying to repack pack-files that have not had their pack-indexes
installed yet.
However, it does cause maintenance to halt if we find the (problematic,
but not insurmountable) case of a .idx file without a corresponding
.pack file. In an environment where packfile maintenance is a critical
function, such a hard stop is costly and requires human intervention to
resolve (by deleting the .idx file).
This was not the case before. We successfully repacked through this
scenario until the recent change to scan for .idx files.
Further, if we are actually in a case where objects are missing, we
detect this at a different point during the reachability walk.
In other cases, Git prepares its list of packfiles by scanning .idx
files and then only adds it to the packfile list if the corresponding
.pack file exists. It even does so without a warning! (See
add_packed_git() in packfile.c for details.)
This case is much less likely to occur than the failures seen before
73320e49ad. Packfiles are "installed" by writing the .pack file before
the .idx and that process can be interrupted. Packfiles _should_ be
deleted by deleting the .idx first, followed by the .pack file, but
unlink_pack_path() does not do this: it deletes the .pack _first_,
allowing a window where this process could be interrupted. We leave the
consideration of changing this order as a separate concern. Knowing that
this condition is possible from interrupted Git processes and not other
tools lends some weight that Git should be more flexible around this
scenario.
Add a check to see if the .pack file exists before adding it to the list
for repacking. This will stop a number of maintenance failures seen in
production but fixed by deleting the .idx files.
This brings us closer to the case before 73320e49ad in that 'git
repack' will not fail when there is an orphaned .idx file, at least, not
due to the way we scan for packfiles. In the case that the .pack file
was erroneously deleted without copies of its objects in other installed
packfiles, then 'git repack' will fail due to the reachable object walk.
This does resolve the case where automated repacks will no longer be
halted on this case. The tests in t7700 show both these successful
scenarios and the case of failing if the .pack was truly required.

The previous commit added low-level tests to ensure that the packed-refs
iterator did not enumerate excluded sections of the refspace.
However, there was no guarantee that these sections weren't being
visited, only that they were being suppressed from the output. To harden
these tests, add a trace2 counter which tracks the number of regions
skipped by the packed-refs iterator, and assert on its value.

When iterating through the `packed-refs` file in order to answer a query
like:
$ git for-each-ref --exclude=refs/__hidden__
it would be useful to avoid walking over all of the entries in
`refs/__hidden__/*` when possible, since we know that the ref-filter
code is going to throw them away anyways.
In certain circumstances, doing so is possible. The algorithm for doing
so is as follows:
- For each excluded pattern, find the first record that matches it,
and the first record that *doesn't* match it (i.e. the location
you'd next want to consider when excluding that pattern).
- Sort the set of excluded regions from the previous step in ascending
order of the first location within the `packed-refs` file that
matches.
- Clean up the results from the previous step: discard empty regions,
and combine adjacent regions. The set of regions which remains is
referred to as the "jump list", and never contains any references
which should be included in the result set.
Then when iterating through the `packed-refs` file, if `iter->pos` is
ever contained in one of the regions from the previous steps, advance
`iter->pos` past the end of that region, and continue enumeration.
Note that we only perform this optimization when none of the excluded
pattern(s) have special meta-characters in them. For a pattern like
"refs/foo[ac]", the excluded regions ("refs/fooa", "refs/fooc", and
everything underneath them) are not connected. A future implementation
that handles this case may split the character class (pretending as if
two patterns were excluded: "refs/fooa", and "refs/fooc").
There are a few other gotchas worth considering. First, note that the
jump list is sorted, so once we jump past a region, we can avoid
considering it (or any regions preceding it) again. The member
`jump_pos` is used to track the first next-possible region to jump
through.
Second, note that the jump list is best-effort, since we do not handle
loose references, and because of the meta-character issue above. The
jump list may not skip past all references which won't appear in the
results, but will never skip over a reference which does appear in the
result set.
In repositories with a large number of hidden references, the speed-up
can be significant. Tests here are done with a copy of linux.git with a
reference "refs/pull/N" pointing at every commit, as in:
$ git rev-list HEAD | awk '{ print "create refs/pull/" NR " " $0 }' |
git update-ref --stdin
$ git pack-refs --all
, it is significantly faster to have `for-each-ref` jump over the
excluded references, as opposed to filtering them out after the fact:
$ hyperfine \
'git for-each-ref --format="%(objectname) %(refname)" | grep -vE "^[0-9a-f]{40} refs/pull/"' \
'git.prev for-each-ref --format="%(objectname) %(refname)" --exclude="refs/pull"' \

176.52 ± 8.19 times faster than 'git for-each-ref --format="%(objectname) %(refname)" | grep -vE "^[0-9a-f]{40} refs/pull/"'
(Comparing stock git and this patch isn't quite fair, since an earlier
commit in this series adds a naive implementation of the `--exclude`
option. `git.prev` is built from the previous commit and includes this
naive implementation).
Using the jump list is fairly straightforward (see the changes to
`refs/packed-backend.c::next_record()`), but constructing the list is
not. To ensure that the construction is correct, add a new suite of
tests in t1419 covering various corner cases (overlapping regions,
partially overlapping regions, adjacent regions, etc.).

When using `for-each-ref`, it is sometimes convenient for the caller to
be able to exclude certain parts of the references.
For example, if there are many `refs/__hidden__/*` references, the
caller may want to emit all references *except* the hidden ones.
Currently, the only way to do this is to post-process the output, like:
$ git for-each-ref --format='%(refname)' | grep -v '^refs/hidden/'
Which is do-able, but requires processing a potentially large quantity
of references.
Teach `git for-each-ref` a new `--exclude=<pattern>` option, which
excludes references from the results if they match one or more excluded
patterns.
This patch provides a naive implementation where the `ref_filter` still
sees all references (including ones that it will discard) and is left to
check whether each reference matches any excluded pattern(s) before
emitting them.
By culling out references we know the caller doesn't care about, we can
avoid allocating memory for their storage, as well as spending time
sorting the output (among other things). Even the naive implementation
provides a significant speed-up on a modified copy of linux.git (that
has a hidden ref pointing at each commit):
$ hyperfine \
'git.compile for-each-ref --format="%(objectname) %(refname)" | grep -vE "[0-9a-f]{40} refs/pull/"' \
'git.compile for-each-ref --format="%(objectname) %(refname)" --exclude refs/pull/'

Range (min … max): 104.7 ms … 109.1 ms 27 runs
Summary
'git.compile for-each-ref --format="%(objectname) %(refname)" --exclude refs/pull/' ran
7.69 ± 0.08 times faster than 'git.compile for-each-ref --format="%(objectname) %(refname)" | grep -vE "[0-9a-f]{40} refs/pull/"'
Subsequent patches will improve on this by avoiding visiting excluded
sections of the `packed-refs` file in certain cases.

Provide a sane initialization value for `struct ref_filter`, which in a
subsequent patch will be used to initialize a new field.
In the meantime, ensure that the `ref_filter` struct used in the

initialization is OK, since `commit_contains()` only looks at the single
`with_commit_tag_algo` field that *is* initialized directly above.

When `git commit-graph verify` was taught how to verify commit-graph
chains in 3da4b609bb (commit-graph: verify chains with --shallow mode,
2019-06-18), it produced one line of progress per layer of the
commit-graph chain.
$ git.compile commit-graph verify
Verifying commits in commit graph: 100% (4356/4356), done.
Verifying commits in commit graph: 100% (131912/131912), done.
This could be somewhat confusing to users, who may wonder why there are
multiple occurrences of "Verifying commits in commit graph".
There are likely good arguments on whether or not there should be
one line of progress output per commit-graph layer. On the one hand, the
existing output shows us verifying each individual layer of the chain.
But on the other hand, the fact that a commit-graph may be stored among
multiple layers is an implementation detail that the caller need not be
aware of.
Clarify this by showing a single progress meter regardless of the number
of layers in the commit-graph chain. After this patch, the output
reflects the logical contents of a commit-graph chain, instead of
showing one line of output per commit-graph layer:

In a similar spirit as the previous commit, address a bug where `git

when invoked with `--no-progress`.
$ git.compile fsck --connectivity-only --no-progress --no-dangling

Verifying object offsets: 100% (605678/605678), done.
The three lines produced by `git fsck` come from `git multi-pack-index
verify`, but should be squelched due to `--no-progress`.
The MIDX machinery learned to generate these progress messages as early
as 430efb8a74 (midx: add progress indicators in multi-pack-index

until ad60096d1c (midx: honor the MIDX_PROGRESS flag in
verify_midx_file, 2019-10-21).
But the `git multi-pack-index verify` step was added to fsck in
66ec0390e7 (fsck: verify multi-pack-index, 2018-09-13), pre-dating any

`--[no-]progress` or not. But in 7371612255 (commit-graph: add
--[no-]progress to write and verify, 2019-08-26), the commit-graph
machinery learned the `--[no-]progress` option, though `fsck` was not
updated to pass this new flag (or not).
This led to seeing output from running `git fsck`, even with
`--no-progress` on repositories that have a commit-graph:
$ git.compile fsck --connectivity-only --no-progress --no-dangling
Verifying commits in commit graph: 100% (4356/4356), done.
Verifying commits in commit graph: 100% (131912/131912), done.
Ensure that `fsck` passes `--[no-]progress` as appropriate when calling
`git commit-graph verify`.

The match_pathspec_item() function takes "prefix" value, allowing a
caller to chop off the common leading prefix of pathspec pattern
strings from the path and only use the remainder of the path to
match the pathspec patterns (after chopping the same leading prefix
of them, of course).
This "common leading prefix" optimization has two main features:
* discard the entries in the in-core index that are outside of the
common leading prefix; if you are doing "ls-files one/a one/b",
we know all matches must be from "one/", so first the code
discards all entries outside the "one/" directory from the
in-core index. This allows us to work on a smaller dataset.
* allow skipping the comparison of the leading bytes when matching
pathspec with path. When "ls-files" finds the path "one/a/1" in
the in-core index given "one/a" and "one/b" as the pathspec,
knowing that common leading prefix "one/" was found lets the
pathspec matchinery not to bother comparing "one/" part, and
allows it to feed "a/1" down, as long as the pathspec element
"one/a" gets corresponding adjustment to "a".
When the "attr" pathspec magic is in effect, however, the current
code breaks down.
The attributes, other than the ones that are built-in and the ones
that come from the $GIT_DIR/info/attributes file and the top-level
.gitattributes file, are lazily read from the filesystem on-demand,
as we encounter each path and ask if it matches the pathspec. For
example, if you say "git ls-files "(attr:label)sub/" in a repository
with a file "sub/file" that is given the 'label' attribute in
"sub/.gitattributes":
* The common prefix optimization finds that "sub/" is the common
prefix and prunes the in-core index so that it has only entries
inside that directory. This is desirable.
* The code then walks the in-core index, finds "sub/file", and
eventually asks do_match_pathspec() if it matches the given
pathspec.
* do_match_pathspec() calls match_pathspec_item() _after_ stripping
the common prefix "sub/" from the path, giving it "file", plus
the length of the common prefix (4-bytes), so that the pathspec
element "(attr:label)sub/" can be treated as if it were "(attr:label)".
The last one is what breaks the match in the current code, as the
pathspec subsystem ends up asking the attribute subsystem to find
the attribute attached to the path "file". We need to ask about the
attributes on "sub/file" when calling match_pathspec_attrs(); this
can be done by looking at "prefix" bytes before the beginning of
"name", which is the same trick already used by another piece of the
code in the same match_pathspec_item() function.
Unfortunately this was not discovered so far because the code works
with slightly different arguments, e.g.
$ git ls-files "(attr:label)sub"
$ git ls-files "(attr:label)sub/" "no/such/dir/"
would have reported "sub/file" as a path with the 'label' attribute
just fine, because neither would trigger the common prefix
optimization.

A few places failed to differenciate the case where the index is
truly empty (nothing added) and we haven't yet read from the
on-disk index file, which have been corrected.
* js/empty-index-fixes:
commit -a -m: allow the top-level tree to become empty again
split-index: accept that a base index can be empty
do_read_index(): always mark index as initialized unless erroring out
The test coverage on attribute magic combined with path pattern
was a bit thin. Let's add a few and make sure "(attr:X)sub" and
"(attr:X)sub/" behave the same.
