"git push $there --delete ''" should have been diagnosed as an
error, but instead turned into a matching push, which has been
corrected.
* jc/push-delete-nothing:
push: do not turn --delete '' into a matching push

When we added a syntax sugar "git push remote --delete <ref>" to
"git push" as a synonym to the canonical "git push remote :<ref>"
syntax at f517f1f2 (builtin-push: add --delete as syntactic sugar
for :foo, 2009-12-30), we weren't careful enough to make sure that
<ref> is not empty.
Blindly rewriting "--delete <ref>" to ":<ref>" means that an empty
string <ref> results in refspec ":", which is the syntax to ask for
"matching" push that does not delete anything.
Worse yet, if there were matching refs that can be fast-forwarded,
they would have been published prematurely, even if the user feels
that they are not ready yet to be pushed out, which would be a real
disaster.

This adds yet another vimdiff/gvimdiff variant and presents conflicts as
a two-way diff between 'LOCAL' and 'REMOTE'. 'MERGED' is not opened
which deviates from the norm so usage text is echoed as a Vim message on
startup that instructs the user with how to proceed and how to abort.
Vimdiff is well-suited to two-way diffs so this is an option for a more
simple, more streamlined conflict resolution. For example: it is
difficult to communicate differences across more than two files using
only syntax highlighting; default vimdiff commands to get and put
changes between buffers do not need the user to manually specify
a source or destination buffer when only using two buffers.
Like other merge tools that directly compare 'LOCAL' with 'REMOTE', this
tool will benefit when paired with the new `mergetool.hideResolved`
setting.

We describe the more strict date formats accepted by GIT_COMMITTER_DATE,
etc, but the --date option also allows the looser approxidate formats,
as well. Unfortunately we don't have a good or complete reference for
this format, but let's at least mention that it _is_ looser, and give a
few examples.
If we ever write separate, more complete date-format documentation, we
should refer to it from here.

The "git maintenance register" command had trouble registering bare

* es/maintenance-of-bare-repositories:
maintenance: fix incorrect `maintenance.repo` path with bare repository

The periodic maintenance tasks configured by `git maintenance start`
invoke `git for-each-repo` to run `git maintenance run` on each path
specified by the multi-value global configuration variable
`maintenance.repo`. Because `git for-each-repo` will likely be run
outside of the repositories which require periodic maintenance, it is
mandatory that the repository paths specified by `maintenance.repo` are
absolute.
Unfortunately, however, `git maintenance register` does nothing to
ensure that the paths it assigns to `maintenance.repo` are indeed
absolute, and may in fact -- especially in the case of a bare repository
-- assign a relative path to `maintenance.repo` instead. Fix this
problem by converting all paths to absolute before assigning them to
`maintenance.repo`.
While at it, also fix `git maintenance unregister` to convert paths to
absolute, as well, in order to ensure that it can correctly remove from
`maintenance.repo` a path assigned via `git maintenance register`.

Various fixes on "git add --chmod".

If `add` encounters an error while applying the --chmod changes, it
prints a message to stderr, but exits with a success code. This might
have been an oversight, as the command does exit with a non-zero code in
other situations where it cannot (or refuses to) update all of the
requested paths (e.g. when some of the given paths are ignored). So make
the exit behavior more consistent by also propagating --chmod errors to
the exit status.
Note: the test "all statuses changed in folder if . is given" uses paths
added by previous test cases, some of which might be symbolic links.
Because `git add --chmod` will now fail with such paths, this test would
depend on whether all the previous tests were executed, or only some
of them. Avoid that by running the test on a fresh repo with only
regular files.

Also use error() instead of fprintf(stderr, ...), to make the

The remove_redundant_with_gen() algorithm performs a depth-first-search
to find commits in the 'array' list, starting at the parents of each
commit in 'array'. The result is that commits in 'array' are marked
STALE when they are reachable from another commit in 'array'.
This depth-first-search is fast when commits lie on or near the
first-parent history of the higher commits. The search terminates early
if all but one commit becomes marked STALE.
However, it is possible that there are two independent commits with high
generation number. In that case, the depth-first-search might languish
by searching in lower generations due to the fixed min_generation used
throughout the method.
With the expectation that commits with lower generation are expected to
become STALE more often, we can optimize further by increasing that
min_generation boundary upon discovery of the commit with minimum
generation.
We must first sort the commits in 'array' by generation. We cannot sort
'array' itself since it must preserve relative order among the returned
results (see revision.c:mark_redundant_parents() for an example).
This simplifies the initialization of min_generation, but it also allows
us to increase the new min_generation when we find the commit with
smallest generation remaining.
This requires more than two commits in order to test, so I used the
Linux kernel repository with a few commits that are slightly off of the
first-parent history. I timed the following command:
git merge-base --independent 2ecedd756908 d2360a398f0b \
1253935ad801 160bab43419e 0e2209629fec 1d0e16ac1a9e
The first two commits have similar generation and are near the v5.10
tag. Commit 160bab43419e is off of the first-parent history behind v5.5,
while the others are scattered somewhere reachable from v5.9. This is
designed to demonstrate the optimization, as that commit within v5.5
would normally cause a lot of extra commit walking.
Since remove_redundant_with_alg() is called only when at least one of
the input commits has a finite generation number, this algorithm is
tested with a commit-graph generated starting at a number of different
tags, the earliest being v5.5.
commit-graph at v5.5:
| Method | Time |
|-----------------------+-------|
| *_no_gen() | 864ms |
| *_with_gen() (before) | 858ms |
| *_with_gen() (after) | 810ms |
commit-graph at v5.7:
| Method | Time |
|-----------------------+-------|
| *_no_gen() | 625ms |
| *_with_gen() (before) | 572ms |
| *_with_gen() (after) | 517ms |
commit-graph at v5.9:
| Method | Time |
|-----------------------+-------|
| *_no_gen() | 268ms |
| *_with_gen() (before) | 224ms |
| *_with_gen() (after) | 202ms |
commit-graph at v5.10:
| Method | Time |
|-----------------------+-------|
| *_no_gen() | 72ms |
| *_with_gen() (before) | 37ms |
| *_with_gen() (after) | 9ms |
Note that these are only modest improvements for the case where the two
independent commits are not in the commit-graph (not until v5.10). All
algorithms get faster as more commits are indexed, which is not a
surprise. However, the cost of walking extra commits is more and more
prevalent in relative terms as more commits are indexed. Finally, the
last case allows us to jump to the minimum generation between the last
two commits (that are actually independent) so we greatly reduce the
cost in that case.

Reachability algorithms in commit-reach.c frequently benefit from using
the first-parent history as a heuristic for satisfying reachability
queries. The most obvious example was implemented in 4fbcca4e
(commit-reach: make can_all_from_reach... linear, 2018-07-20).
Update the walk in remove_redundant() to use this same heuristic. Here,
we are walking starting at the parents of the input commits. Sort those
parents and walk from the highest generation to lower. Each time, use
the heuristic of searching the first parent history before continuing to
expand the walk.
The order in which we explore the commits matters, so update
compare_commits_by_gen to break generation number ties with commit date.
This has no effect when the commits are in a commit-graph file with
corrected commit dates computed, but it will assist when the commits are
in the region "above" the commit-graph with "infinite" generation
number. Note that we cannot shift to use
compare_commits_by_gen_then_commit_date as the method prototype is
different. We use compare_commits_by_gen for QSORT() as opposed to as a
priority function.
The important piece is to ensure we short-circuit the walk when we find
that there is a single non-redundant commit. This happens frequently
when looking for merge-bases or comparing several tags with 'git
merge-base --independent'. Use a new count 'count_still_independent' and
if that hits 1 we can stop walking.
To update 'count_still_independent' properly, we add use of the RESULT
flag on the input commits. Then we can detect when we reach one of these
commits and decrease the count. We need to remove the RESULT flag at
that moment because we might re-visit that commit when popping the
stack.
We use the STALE flag to mark parents that have been added to the new
walk_start list, but we need to clear that flag before we start walking
so those flags don't halt our depth-first-search walk.
On my copy of the Linux kernel repository, the performance of 'git
merge-base --independent <all-tags>' goes from 1.1 seconds to 0.11
seconds.

The current implementation of remove_redundant() uses several calls to
paint_down_to_common() to determine that commits are independent of each
other. This leads to quadratic behavior when many inputs are passed to
commands such as 'git merge-base'.
For example, in the Linux kernel repository, I tested the performance
by passing all tags:
git merge-base --independent $(git for-each-ref refs/tags --format="$(refname)")
(Note: I had to delete the tags v2.6.11-tree and v2.6.11 as they do
not point to commits.)
Here is the performance improvement introduced by this change:
Before: 16.4s
After: 1.1s
This performance improvement requires the commit-graph file to be
present. We keep the old algorithm around as remove_redundant_no_gen()
and use it when generation_numbers_enabled() is false. This is similar
to other algorithms within commit-reach.c. The new algorithm is
implemented in remove_redundant_with_gen().
The basic approach is to do one commit walk instead of many. First, scan
all commits in the list and mark their _parents_ with the STALE flag.
This flag will indicate commits that are reachable from one of the
inputs, except not including themselves. Then, walk commits until
covering all commits up to the minimum generation number pushing the
STALE flag throughout.
At the end, we need to clear the STALE bit from all of the commits
we walked. We move the non-stale commits in 'array' to the beginning of
the list, and this might overwrite stale commits. However, we store an
array of commits that started the walk, and use clear_commit_marks() on
each of those starting commits. That method will walk the reachable
commits with the STALE bit and clear them all. This makes the algorithm
safe for re-entry or for other uses of those commits after this walk.
This logic is covered by tests in t6600-test-reach.sh, so the behavior
does not change. This is tested both in the case with a commit-graph and
without.

Remove a comment at the beggining of remove_redundant() that mentions a
reordering of the input array to have the initial segment be the
independent commits and the final segment be the redundant commits.
While this behavior is followed in remove_redundant(), no callers rely
on that behavior.
Remove the final loop that copies this final segment and update the
comment to match the new behavior.

On a sparse checked out repository, `git grep` (without --cached) ends
up searching the cache when an entry matches the search pathspec and has
the SKIP_WORKTREE bit set. This is confusing both because the sparse
paths are not expected to be in a working tree search (as they are not
checked out), and because the output mixes working tree and cache
results without distinguishing them. (Note that grep also resorts to the
cache on working tree searches that include --assume-unchanged paths.
But the whole point in that case is to assume that the contents of the
index entry and the file are the same. This does not apply to the case
of sparse paths, where the file isn't even expected to be present.)
Fix that by teaching grep to honor the sparse-checkout rules for working
tree searches. If the user wants to grep paths outside the current
sparse-checkout definition, they may either update the sparsity rules to
materialize the files, or use --cached to search all blobs registered in
the index.
Note: it might also be interesting to add a configuration option that
allow users to search paths that are present despite having the
SKIP_WORKTREE bit set, and/or to restrict searches in the index and past
revisions too. These ideas are left as future improvements to avoid
conflicting with other sparse-checkout topics currently in flight.

write_commit_graph initialises topo_levels using init_topo_level_slab(),
next it calls compute_topological_levels() which can cause the slab to
grow, we therefore need to clear the slab again using
clear_topo_level_slab() when we're done.
First introduced in 72a2bfca (commit-graph: add a slab to store
topological levels, 2021-01-16).

`git difftool` only allow us to select file to view in turn.
If there is a commit with many files and we exit in the middle,
we will have to traverse list again to get the file diff which
we want to see. Therefore,teach the command an option
`--skip-to=<path>` to allow the user to say that diffs for earlier
paths are not interesting (because they were already seen in an
earlier session) and start this session with the named path.

Both AsciiDoc and Asciidoctor are eager to pick up the e-mail addresses
in this document and turn them into references at the bottom of the
manpage / clickable links. We don't really need that for these dummy
addresses. Spell "@" as "@" to make them not do this. In the open
block, we can instead avoid this by indenting the contents, similar to
the earlier blocks.
Fix a backtick which should have been a single quote mark. With all the
quoting that is going on around here, this mistake trips up the parsing
and rendering quite a bit.
Before this commit, we have the same failure mode with AsciiDoc 8.6.10
and Asciidoctor 1.5.5, and this change makes both of them happy.

In git-log(1) -- but not in git-shortlog(1) or git-rev-list(1) -- we
include a bonus paragraph in the description of `--first-parent`. But
we forgot to add a lone "+" for a list continuation, and we shouldn't
be indenting this second paragraph. As a result, we get a different
indentation and the `backticks` render literally.

In the implementation of "git difftool", there is a case where the
user wants to start viewing the diffs at a specific path and
continue on to the rest, optionally wrapping around to the
beginning. Since it is somewhat cumbersome to implement such a
feature as a post-processing step of "git diff" output, let's
support it internally with two new options.
- "git diff --rotate-to=C", when the resulting patch would show
paths A B C D E without the option, would "rotate" the paths to
shows patch to C D E A B instead. It is an error when there is
no patch for C is shown.
- "git diff --skip-to=C" would instead "skip" the paths before C,
and shows patch to C D E. Again, it is an error when there is no
patch for C is shown.
- "git log [-p]" also accepts these two options, but it is not an
error if there is no change to the specified path. Instead, the
set of output paths are rotated or skipped to the specified path
or the first path that sorts after the specified path.

With --temp (or --stage=all, which implies --temp), checkout-index
writes a list to stdout associating temporary file names to the entries'
names. But if it fails to write an entry, and the failure happens before
even assigning a temporary filename to that entry, we get an odd output
line. This can be seen when trying to check out a symlink whose blob is
missing:
$ missing_blob=$(git hash-object --stdin </dev/null)
$ git update-index --add --cacheinfo 120000,$missing_blob,foo
$ git checkout-index --temp foo
error: unable to read sha1 file of foo (e69de29bb2d1d6434b8b29ae775ad8c2e48c5391)
foo
The 'TAB foo' line is not much useful and it might break scripts that
expect the 'tempname TAB foo' output. So let's omit such entries from
the stdout list (but leaving the error message on stderr).
We could also consider omitting _all_ failed entries from the output
list, but that's probably not a good idea as the associated tempfiles
may have been created even when checkout failed, so scripts may want to
use the output list for cleanup.

The variables `path` and `ce->name`, at write_entry(), usually have the
same contents, but that's not the case when using a checkout prefix or
writing to a tempfile. (In fact, `path` will be either empty or dirty
when writing to a tempfile.) Therefore, these variables cannot be used
interchangeably. In this sense, fix wrong uses of `path` in error
messages where it should really be `ce->name`, and add some regression
tests. (Note: there doesn't seem to be any misuse in the other way
around.)

When `git blame --color-by-age`, the determine_line_heat() is called to
select how to color the output based on the commit's author date. It
uses the get_commit_info() to parse the information into a `commit_info`
structure, however, this is actually unnecessary because the
determine_line_heat() caller also does the same.
Instead, let's change the determine_line_heat() to take a `commit_info`
structure and remove the internal call to get_commit_info() thus
cleaning up and optimizing the code path.
Enabling Git's trace2 API in order to record the execution time for
every call to determine_line_heat() function:
+ trace2_region_enter("blame", "determine_line_heat", the_repository);
determine_line_heat(ent, &default_color);
+ trace2_region_enter("blame", "determine_line_heat", the_repository);
Then, running `git blame` for "kernel/fork.c" in linux.git and summing
all the execution time for every call (around 1.3k calls) resulted in
2.6x faster execution (best out 3):
