To store the strategy options rebase prepends " --" to each one and
writes them to a file. To load them it reads the file and passes the
contents to split_cmdline(). This roughly mimics the behavior of the
scripted rebase but has a couple of limitations, (1) options containing
whitespace are not properly preserved (this is true of the scripted
rebase as well) and (2) options containing '"' or '\' are incorrectly
parsed and may cause the parser to return an error.
Fix these limitations by quoting each option when they are stored so
that they can be parsed correctly. Now that "--preserve-merges" no
longer exist this change also stops prepending "--" to the options when
they are stored as that was an artifact of the scripted rebase.
These changes are backwards compatible so the files written by an older
version of git can still be read. They are also forwards compatible,
the file can still be parsed by recent versions of git as they treat the
"--" prefix as optional.

When handling "--strategy-option" rebase collects the commands into a
struct string_list, then concatenates them into a string, prepending "--"
to each one before splitting the string and removing the "--" prefix.
This is an artifact of the scripted rebase and the need to support
"rebase --preserve-merges". Now that "--preserve-merges" no-longer
exists we can cleanup the way the argument is handled.
The tests for a bad strategy option are adjusted now that
parse_strategy_opts() is no-longer called when starting a rebase. The
fact that it only errors out when running "git rebase --continue" is a
mixed blessing but the next commit will fix the root cause of the
parsing problem so lets not worry about that here.

Since 1819ad327b (grep: fix multibyte regex handling under macOS,
2022-08-26) we use the system library for all regular expression
matching on macOS, not just for git grep. It supports multi-byte
strings and rejects invalid multi-byte characters.
This broke all built-in userdiff word regexes in UTF-8 locales because
they all include such invalid bytes in expressions that are intended to
match multi-byte characters without explicit support for that from the
regex engine.
"|[^[:space:]]|[\xc0-\xff][\x80-\xbf]+" is added to all built-in word
regexes to match a single non-space or multi-byte character. The \xNN
characters are invalid if interpreted as UTF-8 because they have their
high bit set, which indicates they are part of a multi-byte character,
but they are surrounded by single-byte characters.
Replace that expression with "|[^[:space:]]" if the regex engine
supports multi-byte matching, as there is no need to have an explicit
range for multi-byte characters then. Check for that capability at
runtime, because it depends on the locale and thus on environment
variables. Construct the full replacement expression at build time
and just switch it in if necessary to avoid string manipulation and
allocations at runtime.
Additionally the word regex for tex contains the expression
"[a-zA-Z0-9\x80-\xff]+" with a similarly invalid range. The best
replacement with only valid characters that I can come up with is
"([a-zA-Z0-9]|[^\x01-\x7f])+". Unlike the original it matches NUL
characters, though. Assuming that tex files usually don't contain NUL
this should be acceptable.

As discussed in t/README, tests should aim to use PERL_PATH rather than
straight "perl". We usually do this automatically with a "perl" function
in test-lib.sh, but a few cases need to be handled specially.
One such case is the apply-one-time-perl.sh CGI, which invokes plain
"perl". It should be using $PERL_PATH, but to make that work, we must
also instruct Apache to pass through the variable.
Prior to this patch, doing:
mv /usr/bin/perl /usr/bin/my-perl
make PERL_PATH=/usr/bin/my-perl test
would fail t5702, t5703, and t5616. After this it passes. This is a
pretty extreme case, as even if you install perl elsewhere, you'd likely
still have it in your $PATH. A more realistic case is that you don't
want to use the perl in your $PATH (because it's older, broken, etc) and
expect PERL_PATH to consistently override that (since that's what it's
documented to do). Removing it completely is just a convenient way of
completely breaking it for testing purposes.

When no merge.tool or diff.tool is configured or manually selected, the
selection of a default tool is sensitive to the DISPLAY variable; in a
GUI session a gui-specific tool will be proposed if found, and
otherwise a terminal-based one. This "GUI-optimizing" behavior is
important because a GUI can make a huge difference to a user's ability
to understand and correctly complete a non-trivial conflicting merge.
Some time ago the merge.guitool and diff.guitool config options were
introduced to enable users to configure both a GUI tool, and a non-GUI
tool (with fallback if no GUI tool configured), in the same environment.
Unfortunately, the --gui argument introduced to support the selection of
the guitool is still explicit. When using configured tools, there is no
equivalent of the no-tool-configured "propose a GUI tool if we are in a GUI
environment" behavior.
As proposed in <xmqqmtb8jsej.fsf@gitster.g>, introduce new configuration
options, difftool.guiDefault and mergetool.guiDefault, supporting a special
value "auto" which causes the corresponding tool or guitool to be selected
depending on the presence of a non-empty DISPLAY value. Also support "true"
to say "default to the guitool (unless --no-gui is passed on the
commandline)", and "false" as the previous default behavior when these new
configuration options are not specified.

source repository is not empty.

To check for broken &&-chains, we run "fail_117 && $1" as a test
snippet, and check the exit code. We use test_eval_ to do so, because
that's the way we run the actual test.
But we don't need any of its niceties, like "set -x" tracing. In fact,
they hinder us, because we have to explicitly disable them. So let's
skip that and use "eval" more directly, which is simpler. I had hoped it
would also be faster, but it doesn't seem to produce a measurable
improvement (probably because it's just running internal shell commands,
with no subshells or forks).
Note that there is one gotcha: even though we don't intend to run any of
the commands if the &&-chain is intact, an error like this:
test_expect_success 'broken' '
# this next line breaks the &&-chain
true
# and then this one is executed even by the linter
return 1
'
means we'll "return 1" from the eval, and thus from test_run_(). We
actually do notice this in test_expect_success, but only by saying "hey,
this test didn't say it was OK, so it must have failed", which is not
right (it should say "broken &&-chain").
We can handle this by calling test_eval_inner_() instead, which is our
trick for wrapping "return" in a test snippet. But to do that, we have
to push the trace code out of that inner function and into test_eval_().
This is arguably where it belonged in the first place, but it never
mattered because the "inner_" function had only one caller.

Commit 99a64e4b73 (tests: lint for run-away here-doc, 2017-03-22)
tweaked the chain-lint test to catch unclosed here-docs. It works by
adding an extra "echo" command after the test snippet, and checking that
it is run (if it gets swallowed by a here-doc, naturally it is not run).
The downside here is that we introduced an extra $() substitution, which
happens in a subshell. This has a measurable performance impact when
run for many tests.
The tradeoff in safety was undoubtedly worth it when 99a64e4b73 was
written. But since the external chainlint.pl learned to find these
recently, we can just rely on it. By switching back to a simpler
chain-lint, hyperfine reports a measurable speedup on t3070 (which has
1800 tests):

An unclosed here-doc in a test is a problem, because it silently gobbles
up any remaining commands. Since 99a64e4b73 (tests: lint for run-away
here-doc, 2017-03-22) we detect this by piggy-backing on the internal
chainlint checker in test-lib.sh.
However, it would be nice to detect it in chainlint.pl, for a few
reasons:
- the output from chainlint.pl is much nicer; it can show the exact
spot of the error, rather than a vague "somewhere in this test you
broke the &&-chain or had a bad here-doc" message.
- the implementation in test-lib.sh runs for each test snippet. And
since it requires a subshell, the extra cost is small but not zero.
If chainlint.pl can reliably find the problem, we can optimize the
test-lib.sh code.
The chainlint.pl code never intended to find here-doc problems. But
since it has to parse them anyway (to avoid reporting problems inside
here-docs), most of what we need is already there. We can detect the
problem when we fail to find the missing end-tag in swallow_heredocs().
The extra change in scan_heredoc_tag() stores the location of the start
of the here-doc, which lets us mark it as the source of the error in the
output (see the new tests for examples).

To test that we don't break the &&-chain, test-lib.sh does something
like:
(exit 117) && $test_commands
and checks that the result is exit code 117. We don't care what that
initial command is, as long as it exits with a unique code. Using "exit"
works and is simple, but is a bit expensive since it requires a subshell
(to avoid exiting the whole script!). This isn't usually very
noticeable, but it can add up for scripts which have a large number of
tests.
Using "return" naively won't work here, because we'd return from the
function eval-ing the snippet (and it wouldn't find &&-chain breakages).
But if we further push that into its own function, it does exactly what
we want, without extra subshell overhead.
According to hyperfine, this produces a measurable improvement when
running t3070 (which has 1800 tests, all of them quite short):

Since 69b9924b87 (t/Makefile: teach `make test` and `make prove` to run
chainlint.pl, 2022-09-01), we run a single chainlint.pl process for all
scripts, and then instruct each individual script to run with the
equivalent of --no-chain-lint, which tells them not to redundantly run
the chainlint script themselves.
However, this also disables the internal linter run within the shell by
eval-ing "(exit 117) && $1" and confirming we get code 117. In theory
the external linter produces a superset of complaints, and we don't need
the internal one anymore. However, we know there is at least one case
where they differ. A test like:
test_expect_success 'should fail linter' '
false &&
sleep 2 &
pid=$! &&
kill $pid
'
is buggy (it ignores the failure from "false", because it is
backgrounded along with the sleep). The internal linter catches this,
but the external one doesn't (and teaching it to do so is complicated[1]).
So not only does "make test" miss this problem, but it's doubly
confusing because running the script standalone does complain.
Let's teach the suppression in the Makefile to only turn off the
external linter (which we know is redundant, as it was already run) and
leave the internal one intact.
I've used a new environment variable to do this here, and intentionally
did not add a "--no-ext-chain-lint" option. This is an internal
optimization used by the Makefile, and not something that ordinary users
would need to tweak.

to check for unexpected arguments and complain. But for a test helper,

then it will look for "foo" in the root of the repository, not the
current directory ("subdir/") which the user would have expected.
We can fix this by recording the prefix and using it as appropriate
whenever we open a file for reading or writing. I found each of these by
looking for cases where we call fopen() within fast-import.c, so this
should cover all cases. The new test triggers each one, as well as
making sure we don't accidentally apply the prefix when --relative-marks
is in use (since that option interprets some paths as relative to a
specific directory).
