grep: change non-ASCII -i test to stop using --debug
Change a non-ASCII case-insensitive test case to stop using --debug,
and instead simply test for the expected results.
The test coverage remains the same with this change, but the test
won't break due to internal refactoring.
This test was added in commit 793dc676e0 ("grep/icase: avoid kwsset
when -F is specified", 2016-06-25). It was asserting that the regex
must be compiled with compile_fixed_regexp(), instead test for the
expected results, allowing the underlying implementation to change.

grep: add a test for backreferences in PCRE patterns
Add a test for backreferences such as (.)\1 in PCRE patterns. This
test ensures that the PCRE_NO_AUTO_CAPTURE option isn't turned
on. Before this change turning it on would break these sort of
patterns, but wouldn't break any tests.

grep: add a test asserting that --perl-regexp dies when !PCRE
Add a test asserting that when --perl-regexp (and -P for grep) is
given to git-grep & git-log that we die with an error.
In developing the PCRE v2 series I introduced a regression where -P
would (through control-flow fall-through) become synonymous with basic
POSIX matching. I.e. 'git grep -P '[\d]' would match "d" instead of
digits.
The entire test suite would still pass with this serious regression,
since everything that tested for --perl-regexp would be guarded by the
PCRE prerequisite, fix that blind-spot by adding tests under !PCRE
asserting that git must die when given --perl-regexp or -P.

log: make --regexp-ignore-case work with --perl-regexp
Make the --regexp-ignore-case option work with --perl-regexp. This
never worked, and there was no test for this. Fix the bug and add a
test.
When PCRE support was added in commit 63e7e9d8b6 ("git-grep: Learn
PCRE", 2011-05-09) compile_pcre_regexp() would only check
opt->ignore_case, but when the --perl-regexp option was added in
commit 727b6fc3ed ("log --grep: accept --basic-regexp and
--perl-regexp", 2012-10-03) the code didn't set the opt->ignore_case.
Change the test suite to test for -i and --invert-regexp with
basic/extended/perl patterns in addition to fixed, which was the only
patternType that was tested for before in combination with those
options.

log: add exhaustive tests for pattern style options & config
Add exhaustive tests for how the different grep.patternType options &
the corresponding command-line options affect git-log.
Before this change it was possible to patch revision.c so that the
--basic-regexp option was synonymous with --extended-regexp, and
--perl-regexp wasn't recognized at all, and still have 100% of the
test suite pass.
This was because the first test being modified here, added in commit 34a4ae55b2 ("log --grep: use the same helper to set -E/-F options as
"git grep"", 2012-10-03), didn't actually check whether we'd enabled
extended regular expressions as distinct from re-toggling non-fixed
string support.
Fix that by changing the pattern to a pattern that'll only match if
--extended-regexp option is provided, but won't match under the
default --basic-regexp option.
Other potential regressions were possible since there were no tests
for the rest of the combinations of grep.patternType configuration
toggles & corresponding git-log command-line options. Add exhaustive
tests for those.
The patterns being passed to fixed/basic/extended/PCRE are carefully
crafted to return the wrong thing if the grep engine were to pick any
other matching method than the one it's told to use.

Rename the LIBPCRE prerequisite to PCRE. This is for preparation for
libpcre2 support, where having just "LIBPCRE" would be confusing as it
implies v1 of the library.

grep & rev-list doc: stop promising libpcre for --perl-regexp
Stop promising in our grep & rev-list options documentation that we're
always going to be using libpcre when given the --perl-regexp option.
Instead talk about using "Perl-compatible regular expressions" and
using these types of patterns using "a compile-time dependency".
Saying "libpcre" means that we're talking about libpcre.so, which is
always going to be v1. This change is part of an ongoing saga to add
support for libpcre2, which comes with PCRE v2.
In the future we might use some completely unrelated library to
provide perl-compatible regular expression support. By wording the
documentation differently and not promising any specific version of
PCRE or even PCRE at all we have more wiggle room to change the
implementation.

Makefile & configure: reword inaccurate comment about PCRE
Reword an outdated & inaccurate comment which suggests that only
git-grep can use PCRE.
This comment was added back when PCRE support was initially added in
commit 63e7e9d8b6 ("git-grep: Learn PCRE", 2011-05-09), and was true
at the time.
It hasn't been telling the full truth since git-log learned to use
PCRE with --grep in commit 727b6fc3ed ("log --grep: accept
--basic-regexp and --perl-regexp", 2012-10-03), and more importantly
is likely to get more inaccurate over time as more use is made of PCRE
in other areas.
Reword it to be more future-proof, and to more clearly explain that
this enables user-initiated runtime behavior.
Copy/pasting this so much in configure.ac is lame, these Makefile-like
flags aren't even used by autoconf, just the corresponding
--with[out]-* options. But copy/pasting the comments that make sense
for the Makefile to configure.ac where they make less sense is the
pattern everything else follows in that file. I'm not going to war
against that as part of this change, just following the existing
pattern.

When a remote server uses git-shell, the client side will
connect to it like:
ssh server "git-upload-pack 'foo.git'"
and we literally exec ("git-upload-pack", "foo.git"). In
early versions of upload-pack and receive-pack, we took a
repository argument and nothing else. But over time they
learned to accept dashed options. If the user passes a
repository name that starts with a dash, the results are
confusing at best (we complain of a bogus option instead of
a non-existent repository) and malicious at worst (the user
can start an interactive pager via "--help").
We could pass "--" to the sub-process to make sure the
user's argument is interpreted as a branch name. I.e.:
git-upload-pack -- -foo.git
But adding "--" automatically would make us inconsistent
with a normal shell (i.e., when git-shell is not in use),
where "-foo.git" would still be an error. For that case, the
client would have to specify the "--", but they can't do so
reliably, as existing versions of git-shell do not allow
more than a single argument.
The simplest thing is to simply disallow "-" at the start of
the repo name argument. This hasn't worked either with or
without git-shell since version 1.0.0, and nobody has
complained.
Note that this patch just applies to do_generic_cmd(), which
runs upload-pack, receive-pack, and upload-archive. There
are two other types of commands that git-shell runs:
- do_cvs_cmd(), but this already restricts the argument to
be the literal string "server"
- admin-provided commands in the git-shell-commands
directory. We'll pass along arbitrary arguments there,
so these commands could have similar problems. But these
commands might actually understand dashed arguments, so
we cannot just block them here. It's up to the writer of
the commands to make sure they are safe. With great
power comes great responsibility.

rebase -i: reread the todo list if `exec` touched it
In the scripted version of the interactive rebase, there was no internal
representation of the todo list; it was re-read before every command.
That allowed the hack that an `exec` command could append (or even
completely rewrite) the todo list.
This hack was broken by the partial conversion of the interactive rebase
to C, and this patch reinstates it.
We also add a small test to verify that this fix does not regress in the
future.

t1450: avoid use of "sed" on the index, which is a binary file
The previous step added a path zzzzzzzz to the index, and then used
"sed" to replace this string to yyyyyyyy to create a test case where
the checksum at the end of the file does not match the contents.
Unfortunately, use of "sed" on a non-text file is not portable.
Instead, use a Perl script that seeks to the end and modifies the
last byte of the file (where we _know_ stores the trailing
checksum).

prio_queue_reverse: don't swap elements with themselves
Our array-reverse algorithm does the usual "walk from both
ends, swapping elements". We can quit when the two indices
are equal, since:
1. Swapping an element with itself is a noop.
2. If i and j are equal, then in the next iteration i is
guaranteed to be bigge than j, and we will exit the
loop.
So exiting the loop on equality is slightly more efficient.
And more importantly, the new SWAP() macro does not expect
to handle noop swaps; it will call memcpy() with the same src
and dst pointers in this case. It's unclear whether that
causes a problem on any platforms by violating the
"overlapping memory" constraint of memcpy, but it does cause
valgrind to complain.
