614c3d8f2e test-lib: set GIT_CEILING_DIRECTORIES to protect the surrounding repository
Every once in a while a test somehow manages to escape from its trash
directory and modifies the surrounding repository, whether because of
a bug in git itself, a bug in a test [1], or e.g. when trying to run
tests with a shell that is, in general, unable to run our tests [2].

Set GIT_CEILING_DIRECTORIES="$TRASH_DIRECTORY/.." as an additional
safety measure to protect the surrounding repository at least from
modifications by git commands executed in the tests (assuming that
handling of ceiling directories during repository discovery is not
broken, and, of course, it won't save us from regular shell commands,
e.g. 'cd .. && rm -f ...').

[1] e.g. https://public-inbox.org/git/20210423051255.GD2947267@szeder.dev
[2] $ git symbolic-ref HEAD
    refs/heads/master
    $ ksh ./t2011-checkout-invalid-head.sh
    [... a lot of "not ok" ...]
    $ git symbolic-ref HEAD
    refs/heads/other

    (In short: 'ksh' doesn't support the 'local' builtin command,
    which is used by 'test_oid', causing it to return with error
    whenever it's called, leaving ZERO_OID set to empty, so when the
    test 'checkout main from invalid HEAD' runs 'echo $ZERO_OID
    >.git/HEAD' it writes a corrupt (not invalid) HEAD, and subsequent
    git commands don't recognize the repository in the trash directory
    anymore, but operate on the surrounding repo.)

This allows deleting dangling branches, which previously had to be

c93ca46cf5 column: fix parsing of the '--nl' option
'git column's '--nl' option can be used to specify a "string to be
printed at the end of each line" (quoting the man page), but this
option and its mandatory argument has been parsed as OPT_INTEGER since
the introduction of the command in 7e29b8254f (Add column layout
skeleton and git-column, 2012-04-21).  Consequently, any non-number
argument is rejected by parse-options, and any number other than 0
leads to segfault:

  $ printf "%s\n" one two |git column --mode=plain --nl=foo
  error: option `nl' expects a numerical value
  $ printf "%s\n" one two |git column --mode=plain --nl=42
  Segmentation fault (core dumped)
  $ printf "%s\n" one two |git column --mode=plain --nl=0
  one
  two

Parse this option as OPT_STRING.

8174627b3d diff-lib: ignore paths that are outside $cwd if --relative asked
For diff family commands, we can tell them to exclude changes outside
of some directories if --relative is requested.

In diff_unmerge(), NULL will be returned if the requested path is
outside of the interesting directories, thus we'll run into NULL
pointer dereference in run_diff_files when trying to dereference
its return value.

Checking for return value of diff_unmerge before dereferencing
is not sufficient, though. Since, diff engine will try to work on such
pathspec later.

Let's not run diff on those unintesting entries, instead.
As a side effect, by skipping like that, we can save some CPU cycles.

597fa8cb43 t6300: don't run cat-file on non-existent object
In t6300, some tests are guarded behind some prerequisites.
Thus, objects created by those tests ain't available if those
prerequisites are unsatistified.  Attempting to run "cat-file"
on those objects will run into failure.

In fact, running t6300 in an environment without gpg(1),
we'll see those warnings:

	fatal: Not a valid object name refs/tags/signed-empty
	fatal: Not a valid object name refs/tags/signed-short
	fatal: Not a valid object name refs/tags/signed-long

Let's put those commands into the real tests, in order to:

* skip their execution if prerequisites aren't satistified.
* check their exit status code

The expected value for objects with type: commit needs to be
computed outside the test because we can't rely on "$3" there.
Furthermore, to prevent the accidental usage of that computed
expected value, BUG out on unknown object's type.

c21b2511c2 t5323: drop mentions of "master"
Commit 0696232390 (pack-redundant: fix crash when one packfile in repo,
2020-12-16) added one some new tests to t5323. At the time, the sub-repo
we used was called "master". But in a parallel branch, this was switched
to "main".

When the latter branch was merged in 27d7c8599b (Merge branch
'js/default-branch-name-tests-final-stretch', 2021-01-25), some of those
spots caused textual conflicts, but some (for tests that were far enough
away from other changed code) were just semantic. The merge resolution
fixed up most spots, but missed this one.

Even though this did impact actual code, it turned out not to fail the
tests. Running 'cd "$master_repo"' ended up staying in the same
directory, running the test in the main trash repo instead of the
sub-repo. But because the point of the test is checking behavior when
there are no packfiles, it worked in either repo (since both are empty
at this point in the script).

a16eb6b1ff maintenance: skip bootout/bootstrap when plist is registered
On macOS, we use launchctl to manage the background maintenance
schedule. This uses a set of .plist files to describe the schedule, but
these files are also registered with 'launchctl bootstrap'. If multiple
'git maintenance start' commands run concurrently, then they can collide
replacing these schedule files and registering them with launchctl.

To avoid extra launchctl commands, do a check for the .plist files on
disk and check if they are registered using 'launchctl list <name>'.
This command will return with exit code 0 if it exists, or exit code 113
if it does not.

We can test this behavior using the GIT_TEST_MAINT_SCHEDULER environment
variable.

f172556b89 cherry-pick: use better advice message
"git cherry-pick", upon seeing a conflict, says:

hint: after resolving the conflicts, mark the corrected paths
hint: with 'git add <paths>' or 'git rm <paths>'
hint: and commit the result with 'git commit'

as if running "git commit" to conclude the resolution of
this single step were the end of the story.  This stems from
the fact that the command originally was to pick a single
commit and not a range of commits, and the message was
written back then and has not been adjusted.

When picking a range of commits and the command stops with a
conflict in the middle of the range, however, after
resolving the conflict and (optionally) recording the result
with "git commit", the user has to run "git cherry-pick
--continue" to have the rest of the range dealt with,
"--skip" to drop the current commit, or "--abort" to discard
the series.

Suggest use of "git cherry-pick --continue/--skip/--abort"
so that the message also covers the case where a range of
commits are being picked.

Similarly, this optimization can be applied to git revert,
suggest use of "git revert --continue/--skip/--abort" so
that the message also covers the case where a range of
commits are being reverted.

It is worth mentioning that now we use advice() to print
the content of GIT_CHERRY_PICK_HELP in print_advice(), each
line of output will start with "hint: ".

f2563c9ef3 rebase -r: fix merge -c with a merge strategy
If a rebase is started with a --strategy option other than "ort" or
"recursive" then "merge -c" does not allow the user to reword the
commit message.

baf8ec8d3a rebase -r: don't write .git/MERGE_MSG when fast-forwarding
When fast-forwarding we do not create a new commit so .git/MERGE_MSG
is not removed and can end up seeding the message of a commit made
after the rebase has finished. Avoid writing .git/MERGE_MSG when we
are fast-forwarding by writing the file after the fast-forward
checks. Note that there are no changes to the fast-forward code, it is
simply moved.

Note that the way this change is implemented means we no longer write
the author script when fast-forwarding either. I believe this is safe
for the reasons below but it is a departure from what we do when
fast-forwarding a non-merge commit. If we reword the merge then 'git
commit --amend' will keep the authorship of the commit we're rewording
as it ignores GIT_AUTHOR_* unless --reset-author is passed. It will
also export the correct GIT_AUTHOR_* variables to any hooks and we
already test the authorship of the reworded commit. If we are not
rewording then we no longer call spilt_ident() which means we are no
longer checking the commit author header looks sane. However this is
what we already do when fast-forwarding non-merge commits in
skip_unnecessary_picks() so I don't think we're breaking any promises
by not checking the author here.

0c164ae7a6 rebase -i: add another reword test
None of the existing reword tests check that there are no uncommitted
changes when the editor is opened. Reuse the editor script from the
last commit to fix this omission.

2be6b6f411 rebase -r: make 'merge -c' behave like reword
If the user runs git log while rewording a commit it is confusing if
sometimes we're amending the commit that's being reworded and at other
times we're creating a new commit depending on whether we could
fast-forward or not[1]. For this reason the reword command ensures
that there are no uncommitted changes when rewording. The reword
command also allows the user to edit the todo list while the rebase is
paused. As 'merge -c' also rewords commits make it behave like reword
and add a test.

e9f2118ddf completion: bash: fix for suboptions with value
We need to ignore options that don't start with -- as well.

Depending on the value of COMP_WORDBREAKS the last word could be
duplicated otherwise.

Can be tested with:

  git merge -X diff-algorithm=<tab>
