This reverts commit 7e25437d35a70791b345872af202eabfb3e1a8bc, reversing
changes made to 00624d608cc69bd62801c93e74d1ea7a7ddd6598.
v2.19.0-rc0~165^2~1 (submodule: ensure core.worktree is set after
update, 2018-06-18) assumes an "absorbed" submodule layout, where the
submodule's Git directory is in the superproject's .git/modules/
directory and .git in the submodule worktree is a .git file pointing
there. In particular, it uses $GIT_DIR/modules/$name to find the
submodule to find out whether it already has core.worktree set, and it
uses connect_work_tree_and_git_dir if not, resulting in
fatal: could not open sub/.git for writing
The context behind that patch: v2.19.0-rc0~165^2~2 (submodule: unset
core.worktree if no working tree is present, 2018-06-12) unsets
core.worktree when running commands like "git checkout
--recurse-submodules" to switch to a branch without the submodule. If
a user then uses "git checkout --no-recurse-submodules" to switch back
to a branch with the submodule and runs "git submodule update", this
patch is needed to ensure that commands using the submodule directly
are aware of the path to the worktree.
It is late in the release cycle, so revert the whole 3-patch series.
We can try again later for 2.20.

According to RFC3875, empty environment variable is equivalent to unset,
and for CONTENT_LENGTH it should mean zero body to read.
However, unset CONTENT_LENGTH is also used for chunked encoding to indicate
reading until EOF. At least, the test "large fetch-pack requests can be split
across POSTs" from t5551 starts faliing, if unset or empty CONTENT_LENGTH is
treated as zero length body. So keep the existing behavior as much as possible.
Add a test for the case.

Recent addition of "directory rename" heuristics to the
merge-recursive backend makes the command susceptible to false
positives and false negatives. In the context of "git am -3",
which does not know about surrounding unmodified paths and thus
cannot inform the merge machinery about the full trees involved,
this risk is particularly severe. As such, the heuristic is
disabled for "git am -3" to keep the machinery "more stupid but
predictable".

Let's say you have the following three trees, where Base is from one commit
behind either master or branch:
Base : bar_v1, foo/{file1, file2, file3}
branch: bar_v2, foo/{file1, file2}, goo/file3
master: bar_v3, foo/{file1, file2, file3}
Using git-am (or am-based rebase) to apply the changes from branch onto
master results in the following tree:
Result: bar_merged, goo/{file1, file2, file3}
This is not what users want; they did not rename foo/ -> goo/, they only
renamed one file within that directory. The reason this happens is am
constructs fake trees (via build_fake_ancestor()) of the following form:
Base_bfa : bar_v1, foo/file3
branch_bfa: bar_v2, goo/file3
Combining these two trees with master's tree:
master: bar_v3, foo/{file1, file2, file3},
You can see that merge_recursive_generic() would see branch_bfa as renaming
foo/ -> goo/, and master as just adding both foo/file1 and foo/file2. As
such, it ends up with goo/{file1, file2, file3}
The core problem is that am does not have access to the original trees; it
can only construct trees using the blobs involved in the patch. As such,
it is not safe to perform directory rename detection within am -3.

On both AIX 7200-00-01-1543 and FreeBSD 11.2-RELEASE-p2 the
"${var:-"str"}" syntax means something different than what it does
under the bash or dash shells.
Both will consider the start of the new unescaped quotes to be a new
argument to test_expect_success, resulting in the following error:
error: bug in the test script: 'git diff-tree initial # magic

Fix this by removing the redundant quotes. There's no need for them,
and the resulting code works under all the aforementioned shells. This
fixes a regression in c2f1d3989 ("t4013: test new output from diff

The test guarded by PERLJSON added in 75459410ed ("json_writer: new
routines to create JSON data", 2018-07-13) assumed that a JSON boolean
value like "true" or "false" would be represented as "1" or "0" in
Perl.
This behavior can't be relied upon, e.g. with JSON.pm 2.50 and
JSON::PP. A JSON::PP::Boolean object will be represented as "true"
or "false". To work around this let's check if we have any refs left
after we check for hashes and arrays, assume those are JSON objects,
and coerce them to a known boolean value.
The behavior of this test still looks odd to me. Why implement our own
ad-hoc encoder just for some one-off test, as opposed to say Perl's
own Data::Dumper with Sortkeys et al? But with this change it works,
so let's leave it be.

The seq command is not in POSIX, and doesn't exist on
e.g. OpenBSD. We've had the test_seq wrapper since d17cf5f3a3 ("tests:
Introduce test_seq", 2012-08-04), but use of it keeps coming back,
e.g. in the recently added "fetch negotiator" tests being added here.
So let's also add a check to "make test-lint". The regex is aiming to
capture the likes of $(seq ..) and "seq" as a stand-alone command,
without capturing some existing cases where we e.g. have files called
"seq", as \bseq\b would do.

The "head -c BYTES" option is non-portable (not in POSIX[1]). Change
such invocations to use the test_copy_bytes wrapper added in
48860819e8 ("t9300: factor out portable "head -c" replacement",
2016-06-30).
This fixes a test added in 9d2e330b17 ("ewah_read_mmap: bounds-check
mmap reads", 2018-06-14), which has been breaking
t5310-pack-bitmaps.sh on OpenBSD since 2.18.0. The OpenBSD ports
already have a similar workaround after their upgrade to 2.18.0[2].
I have not tested this on IRIX, but according to 4de0bbd898 ("t9300:
use perl "head -c" clone in place of "dd bs=1 count=16000" kluge",
2010-12-13) this invocation would have broken things there too.
Also, change a valgrind-specific codepath in test-lib.sh to use this
wrapper. Given where valgrind runs I don't think this would ever
become a portability issue in practice, but it's easier to just use
the wrapper than introduce some exception for the "make test-lint"
check being added here.

The verbose output of the test 'reword without issues functions as
intended' in 't3423-rebase-reword.sh', added in a9279c6785 (sequencer:
do not squash 'reword' commits when we hit conflicts, 2018-06-19),
contains the following error output:
sed: -e expression #1, char 2: extra characters after command
This error comes from within the 'fake-editor.sh' script created by
'lib-rebase.sh's set_fake_editor() function, and the root cause is the
FAKE_LINES="pick 1 reword 2" variable in the test in question, in
particular the "pick" word. 'fake-editor.sh' assumes 'pick' to be the
default rebase command and doesn't support an explicit 'pick' command
in FAKE_LINES. As a result, 'pick' will be used instead of a line
number when assembling the following 'sed' script:
sed -n picks/^pick/pick/p
which triggers the aforementioned error.
Luckily, this didn't affect the test's correctness: the erroring 'sed'
command doesn't write anything to the todo script, and processing the
rest of FAKE_LINES generates the desired todo script, as if that
'pick' command were not there at all.
The minimal fix would be to remove the 'pick' word from FAKE_LINES,
but that would leave us susceptible to similar issues in the future.
Instead, teach the fake-editor script to recognize an explicit 'pick'
command, which is still a fairly trivial change.
In the future we might want to consider reinforcing this fake editor
script with an &&-chain and stricter parsing of the FAKE_LINES
variable (e.g. to error out when encountering unknown rebase commands
or commands and line numbers in the wrong order).

When we originally did the series that contains 7ba826290a
(revision: add rev_input_given flag, 2017-08-02) the intent
was that "git rev-list --stdin </dev/null" would similarly
become a successful noop. However, an attempt at the time to
do that did not work[1]. The problem is that rev_input_given
serves two roles:
- it tells rev-list.c that it should not error out
- it tells revision.c that it should not have the "default"
ref kick (e.g., "HEAD" in "git log")
We want to trigger the former, but not the latter. This is
technically possible with a single flag, if we set the flag
only after revision.c's revs->def check. But this introduces
a rather subtle ordering dependency.
Instead, let's keep two flags: one to denote when we got
actual input (which triggers both roles) and one for when we
read stdin (which triggers only the first).
This does mean a caller interested in the first role has to
check both flags, but there's only one such caller. And any
future callers might want to make the distinction anyway
(e.g., if they care less about erroring out, and more about
whether revision.c soaked up our stdin).
In fact, we already keep such a flag internally in
revision.c for this purpose, so this is really just exposing
that to the caller (and the old function-local flag can go
away in favor of our new one).

Several tests in 't3420-rebase-autostash.sh' start various rebase
processes that are expected to fail because of merge conflicts. These
tests then run '! grep' to ensure that the autostash feature did its
job, and the dirty contents of a file is gone. However, due to the
test repo's history and the choice of upstream branch that file
shouldn't exist in the conflicted state at all. Consequently, this
'grep' doesn't fail as expected, because it can't find the dirty
content, but it fails because it can't open the file.
Tighten this check by using 'test_path_is_missing' instead, thereby

Prior to d3c6751b18 (tests: make use of the test_must_be_empty
function, 2018-07-27), in the test 'rev-list should succeed with empty
output on empty stdin' in 't6018-rev-list-glob' the empty 'expect'
file served dual purpose: besides specifying the expected output, as
usual, it also served as empty input for 'git rev-list --stdin'.
Then d3c6751b18 came along, and, as part of the conversion to
'test_must_be_empty', removed this empty 'expect' file, not realizing
its secondary purpose. Redirecting stdin from the now non-existing
file failed the test, but since this test expects failure in the first
place, this issue went unnoticed.
Redirect 'git rev-list's stdin explicitly from /dev/null to provide
empty input. (Strictly speaking we don't need this redirection,
because the test script's stdin is already redirected from /dev/null
anyway, but I think it's better to be explicit about it.)

The test ' context does not include preceding empty lines' in the
block of tests 'change with long common tail and no context' in
't4051-diff-function-context.sh' tries to read the file
'long_common_tail.diff.diff', but that file doesn't exist as its name
contains one more '.diff' suffixes than necessary.
Despite this error the test still succeeded without checking what it's
supposed to, because this erroneous read is done on the line:
test "$(first_context_line <long_common_tail.diff.diff)" != " "
which means that:
- the command substitution hides the error, so it won't fail the
test, and
- the result of the command substitution is the empty string, which
is, of course, not equal to a single space character, so the
condition is fulfilled, and the test succeeds.
As a minimal fix, fix the name of the file to be read.
In the future we might want to reorganize this test script (1) to use
'test_cmp' instead of 'test's and command substitutions to catch
failing commands and to provide helpful error messages, and (2) to
specify what the expected result actually _is_ instead of what it
isn't.

In the test 'checkout with autocrlf=input' in 't0020-crlf.sh', one of
the 'has_cr' checks looks at the non-existing file 'two' instead of
'dir/two'. The test still succeeds, without actually checking what it
was supposed to, because this check is expected to fail anyway.
As a minimal fix, fix the name of the file to be checked.

The test '--dry-run with conflicts fixed from a merge' in
't7501-commit.sh', added in 8dc874b2ee (wt-status.c: set commitable
bit if there is a meaningful merge., 2016-02-15), runs the following
unnecessary and downright bogus command substitution:
! $(git merge --no-commit commit-1) &&
I.e. after 'git merge ...' is executed and expectedly fails, the test
attempts to execute its output:
Merging:
80f2ea2 commit 2
virtual commit-1
found 1 common ancestor:
e60d113 Initial commit
Auto-merging test-file
CONFLICT (content): Merge conflict in test-file
Automatic merge failed; fix conflicts and then commit the result.
as a command, which most likely fails, because there is no such
command as "Merging:". Then '!' negates the failed exit status, the
test continues, and eventually succeeds.
Remove this command substitution and use 'test_must_fail' to ensure
that 'git merge' fails.

The test-tool programs include "test-tool.h" as their first
include, which breaks our CodingGuideline of "the first
include must be git-compat-util.h or an equivalent".
Rather than change them all, let's instead make test-tool.h
one of those equivalents, just like we do for builtin.h
(which many of the actual git builtins include first).

Using 'test_must_be_empty' is shorter and more idiomatic than
>empty &&
test_cmp empty out
as it saves the creation of an empty file. Furthermore, sometimes the
expected empty file doesn't have such a descriptive name like 'empty',
and its creation is far away from the place where it's finally used
for comparison (e.g. in 't7600-merge.sh', where two expected empty
files are created in the 'setup' test, but are used only about 500
lines later).
These cases were found by instrumenting 'test_cmp' to error out the
test script when it's used to compare empty files, and then converted
manually.
Note that even after this patch there still remain a lot of cases
where we use 'test_cmp' to check empty files:
- Sometimes the expected output is not hard-coded in the test, but
'test_cmp' is used to ensure that two similar git commands produce
the same output, and that output happens to be empty, e.g. the
test 'submodule update --merge - ignores --merge for new
submodules' in 't7406-submodule-update.sh'.
- Repetitive common tasks, including preparing the expected results
and running 'test_cmp', are often extracted into a helper
function, and some of this helper's callsites expect no output.
- For the same reason as above, the whole 'test_expect_success'
block is within a helper function, e.g. in 't3070-wildmatch.sh'.
- Or 'test_cmp' is invoked in a loop, e.g. the test 'cvs update
(-p)' in 't9400-git-cvsserver-server.sh'.
