fb89888849 dir: hide untracked contents of untracked dirs
When we taught read_directory_recursive() to recurse into untracked
directories in search of ignored files given DIR_SHOW_IGNORED_TOO, that
had the side effect of teaching it to collect the untracked contents of
untracked directories. It doesn't always make sense to return these,
though (we do need them for `clean -d`), so we introduce a flag
(DIR_KEEP_UNTRACKED_CONTENTS) to control whether or not read_directory()
strips dir->entries of the untracked contents of untracked dirs.

We also introduce check_contains() to check if one dir_entry corresponds
to a path which contains the path corresponding to another dir_entry.

This also fixes known breakages in t7061, since status --ignored now
searches untracked directories for ignored files.

0a81d4a559 t7061: status --ignored should search untracked dirs
Per eb8c5b87, `status --ignored` by design does not list ignored files
if they are in a directory which contains only ignored and untracked
files (which is itself considered to be untracked) without `-uall`. This
does not make sense for `--ignored`, which claims to "Show ignored files
as well."

Thus we revisit eb8c5b87 and decide that for such directories, `status
--ignored` will list the directory as untracked *and* list all ignored
files within said directory even without `-uall`.

If git sees a directory which contains only untracked and ignored

88b6197d0b perf: add a GIT_PERF_MAKE_COMMAND for when *_MAKE_OPTS won't do
Add a git GIT_PERF_MAKE_COMMAND variable to compliment the existing
GIT_PERF_MAKE_OPTS facility. This allows specifying an arbitrary shell
command to execute instead of 'make'.

This is useful e.g. in cases where the name, semantics or defaults of
a Makefile flag have changed over time. It can even be used to change
the contents of the tree, useful for monkeypatching ancient versions
of git to get them to build.

This opens Pandora's box in some ways, it's now possible to
"jailbreak" the perf environment and e.g. modify the source tree via
this arbitrary instead of just issuing a custom "make" command, such a
command has to be re-entrant in the sense that subsequent perf runs
will re-use the possibly modified tree.

It would be pointless to try to mitigate or work around that caveat in
a tool purely aimed at Git developers, so this change makes no attempt
to do so.

966be95549 grep: add tests to fix blind spots with \0 patterns
Address a big blind spot in the tests for patterns containing \0. The
is_fixed() function considers any string that contains \0 fixed, even
if it contains regular expression metacharacters, those patterns are
currently matched with kwset.

Before this change removing that memchr(s, 0, len) check from
is_fixed() wouldn't change the result of any of the tests, since
regcomp() will happily match the part before the \0.

The kwset path is dependent on whether the the -i flag is on, and
whether the pattern has any non-ASCII characters, but none of this was
tested for.

12fc32faa8 grep: prepare for testing binary regexes containing rx metacharacters
Add setup code needed for testing regexes that contain both binary
data and regex metacharacters.

The POSIX regcomp() function inherently can't support that, because it
takes a \0-delimited char *, but other regex engines APIs like PCRE v2
take a pattern/length pair, and are thus able to handle \0s in
patterns as well as any other character.

When kwset was imported in commit 9eceddeec6 ("Use kwset in grep",
2011-08-21) this limitation was fixed, but at the expense of
introducing the undocumented limitation that any pattern containing \0
implicitly becomes a fixed match (equivalent to -F having been
provided).

That's not something we'd like to keep in the future. The inability to
match patterns containing \0 is a leaky implementation detail.

So add tests as a first step towards changing that. In order to test
that \0-patterns can properly match as regexes the test string needs
to have some regex metacharacters in it.

There were other blind spots in the tests. The code around kwset
specially handles case-insensitive & non-ASCII data, but there were no
tests for this.

Fix all of that by amending the text being matched to contain both
regex metacharacters & non-ASCII data.

5d52a30eda grep: amend submodule recursion test for regex engine testing
Amend the submodule recursion test to prepare it for subsequent tests
of whether it passes along the grep.patternType to the submodule
greps.

This is the result of searching & replacing:

    foobar -> (1|2)d(3|4)
    foo    -> (1|2)
    bar    -> (3|4)

Currently there's no tests for whether e.g. -P or -E is correctly
passed along, tests for that will be added in a follow-up change, but
first add content to the tests which will match differently under
different regex engines.

Reuse the pattern established in an earlier commit of mine in this
series ("log: add exhaustive tests for pattern style options &
config", 2017-04-07). The pattern "(.|.)[\d]" will match this content
differently under fixed/basic/extended & perl.

This test code was originally added in commit 0281e487fd ("grep:
optionally recurse into submodules", 2016-12-16).

c5813658f7 grep: add tests for --threads=N and grep.threads
Add tests for --threads=N being supplied on the command-line, or when
grep.threads=N being supplied in the configuration.

When the threading support was made run-time configurable in commit
89f09dd34e ("grep: add --threads=<num> option and grep.threads
configuration", 2015-12-15) no tests were added for it.

In developing a change to the grep code I was able to make
'--threads=1 <pat>` segfault, while the test suite still passed. This
change fixes that blind spot in the tests.

In addition to asserting that asking for N threads shouldn't segfault,
test that the grep output given any N is the same.

The choice to test only 1..10 as opposed to 1..8 or 1..16 or whatever
is arbitrary. Testing 1..1024 works locally for me (but gets
noticeably slower as more threads are spawned). Given the structure of
the code there's no reason to test an arbitrary number of threads,
only 0, 1 and >=2 are special modes of operation.

A later patch introduces a PTHREADS test prerequisite which is true
under NO_PTHREADS=UnfortunatelyYes, but even under NO_PTHREADS it's
fine to test --threads=N, we'll just ignore it and not use
threading. So these tests also make sense under that mode to assert
that --threads=N without pthreads still returns expected results.

9001c1920c 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.

Make the --regexp-ignore-case option work with --perl-regexp. This

When PCRE support was added in commit 63e7e9d8b6 ("git-grep: Learn

opt->ignore_case, but when the --perl-regexp option was added in

--perl-regexp", 2012-10-03) the code didn't set the opt->ignore_case.

basic/extended/perl patterns in addition to fixed, which was the only
patternType that was tested for before in combination with those
options.

9df46763ef 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.

edf3b90553 unpack-trees: preserve index extensions
Make git checkout (and other unpack_tree operations) preserve the
untracked cache. This is valuable for two reasons:

1. Often, an unpack_tree operation will not touch large parts of the
working tree, and thus most of the untracked cache will continue to be
valid.

2. Even if the untracked cache were entirely invalidated by such an
operation, the user has signaled their intention to have such a cache,
and we don't want to throw it away.

d76650b8d1 interpret-trailers: honor the cut line
If a commit message is edited with the "verbose" option, the buffer
will have a cut line and diff after the log message, like so:

    my subject

    # ------------------------ >8 ------------------------
    # Do not touch the line above.
    # Everything below will be removed.
    diff --git a/foo.txt b/foo.txt
    index 5716ca5..7601807 100644
    --- a/foo.txt
    +++ b/foo.txt
    @@ -1 +1 @@
    -bar
    +baz

"git interpret-trailers" is unaware of the cut line, and assumes the
trailer block would be at the end of the whole thing.  This can easily
be seen with:

     $ GIT_EDITOR='git interpret-trailers --in-place --trailer Acked-by:me' \
       git commit --amend -v

Teach "git interpret-trailers" to notice the cut-line and ignore the
remainder of the input when looking for a place to add new trailer
block.  This makes it consistent with how "git commit -v -s" inserts a
new Signed-off-by: line.

This can be done by the same logic as the existing helper function,
wt_status_truncate_message_at_cut_line(), uses, but it wants the caller
to pass a strbuf to it.  Because the function ignore_non_trailer() used
by the command takes a <pointer, length> pair, not a strbuf, steal the
logic from wt_status_truncate_message_at_cut_line() to create a new
wt_status_locate_end() helper function that takes <pointer, length>
pair, and make ignore_non_trailer() call it to help "interpret-trailers".

Since there is only one caller of wt_status_truncate_message_at_cut_line()
in cmd_commit(), rewrite it to call wt_status_locate_end() helper instead
and remove the old helper that no longer has any caller.

71406ed4d6 t5400: avoid concurrent writes into a trace file
One test in t5400 examines the packet exchange between git-push and
git-receive-pack. The latter inherits the GIT_TRACE_PACKET environment
variable, so that both processes dump trace data into the same file
concurrently. This should not be a problem because the trace file is
opened with O_APPEND.

On Windows, however, O_APPEND is not atomic as it should be: it is
emulated as lseek(SEEK_END) followed by write(). For this reason, the
test is unreliable: it can happen that one process overwrites a line
that was just written by the other process. As a consequence, the test
sometimes does not find one or another line that is expected (and it is
also successful occasionally).

The test case is actually only interested in the output of git-push.
To ensure that only git-push writes to the trace file, override the
receive-pack command such that it does not even open the trace file.

tests), but not very much (i.e. TAP wasn't told how many tests are

Don't abort the whole test script in that case, but simply skip the
multi-threaded performance check.  We can still use it to compare the
single-threaded speed of different versions in that case.

The perf test suite (more specifically: t/perf/aggregate.perl) requires
each test script to write test results into a file, otherwise it aborts
when aggregating.  Add actual performance tests with test_perf to allow
p0004 to be run together with other perf scripts.

Calibrate the value for the parameter --count based on the size of the
test repository, in order to get meaningful results with smaller repos
yet still be able to finish the script against huge ones without having
to wait for hours.

fdb69d33c4 fetch-pack: always allow fetching of literal SHA1s
fetch-pack, when fetching a literal SHA-1 from a server that is not
configured with uploadpack.allowtipsha1inwant (or similar), always
returns an error message of the form "Server does not allow request for
unadvertised object %s". However, it is sometimes the case that such
object is advertised. This situation would occur, for example, if a user
or a script was provided a SHA-1 instead of a branch or tag name for
fetching, and wanted to invoke "git fetch" or "git fetch-pack" using
that SHA-1.

Teach fetch-pack to also check the SHA-1s of the refs in the received
ref advertisement if a literal SHA-1 was given by the user.

c74271aae7 builtin/log: honor log.decorate
The recent change that introduced autodecorating of refs accidentally
broke the ability of users to set log.decorate = false to override it.
When the git_log_config was traversed a second time with an option other
than log.decorate, the decoration style would be set to the automatic
style, even if the user had already overridden it.  Instead of setting
the option in config parsing, set it in init_log_defaults instead.

Add a test for this case.  The actual additional config option doesn't
matter, but it needs to be something not already set in the
configuration file.

25cd291963 config: complain about --local outside of a git repo
The "--local" option instructs git-config to read or modify
the repository-level config. This doesn't make any sense if
you're not actually in a repository.

Older versions of Git would blindly try to read or write
".git/config". For reading, this would result in a quiet
failure, since there was no config to read (and thus no
matching config value). Writing would generally fail
noisily, since ".git" was unlikely to exist. But since
b1ef400ee (setup_git_env: avoid blind fall-back to ".git",
2016-10-20), we catch this in the call to git_pathdup() and
die with an assertion.

Dying is the right thing to do, but we should catch the
problem early and give a more human-friendly error message.

Note that even without --local, git-config will sometimes
default to using local repository config (e.g., when
writing). These cases are already protected by similar
checks, and covered by a test in t1308.

62ca75a6b9 perf: add test showing exponential growth in path globbing
Add a test showing that runtimes of the wildmatch() function used for
globbing in git grow exponentially in the face of some pathological
globs.

This issue affects both globs matching filenames via e.g. ls-files,
and globs matching refnames via e.g. for-each-ref.

As noted in the test description this is a test to see whether Git
suffers from the issue noted in an article Russ Cox posted today about
common bugs in various glob implementations:

Some performance tests don't need any existing repository data at all
to be significant, e.g. tests which stress glob matches against single
pathological revisions or files, which I'm about to add in a
subsequent commit.
