Now that the default value for TEST_PASSES_SANITIZE_LEAK is `true` there
is no longer a need to have that variable declared in all of our tests.

When passing untracked path with -u option, it silently succeeds.
There is no error message and the exit code is zero. This is
inconsistent with other instances of git commands where the expected
argument is a known path. In those other instances, we error out when
the path is not known.
Fix this by passing a character array to add_files_to_cache() to
collect the pathspec matching information and report the error if a
pathspec does not match any cache entry. Also add a testcase to cover
this scenario.

In 03267e8656c (commit: discard partial cache before (re-)reading it,
2022-11-08), a memory leak was plugged by discarding any partial index
before re-reading it.
The problem with this memory leak fix is that it was based on an
incomplete understanding of the logic introduced in 7168624c353 (Do not
generate full commit log message if it is not going to be used,
2007-11-28).
That logic was introduced to add a shortcut when committing without
editing the commit message interactively. A part of that logic was to
ensure that the index was read into memory:
if (!active_nr && read_cache() < 0)
die(...)
Translation to English: If the index has not yet been read, read it, and
if that fails, error out.
That logic was incorrect, though: It used `!active_nr` as an indicator
that the index was not yet read. Usually this is not a problem because
in the vast majority of instances, the index contains at least one
entry.
And it was natural to do it this way because at the time that condition
was introduced, the `index_state` structure had no explicit flag to
indicate that it was initialized: This flag was only introduced in
913e0e99b6a (unpack_trees(): protect the handcrafted in-core index from
read_cache(), 2008-08-23), but that commit did not adjust the code path
where no index file was found and a new, pristine index was initialized.
Now, when the index does not contain any entry (which is quite
common in Git's test suite because it starts quite a many repositories
from scratch), subsequent calls to `do_read_index()` will mistake the
index not to be initialized, and read it again unnecessarily.
This is a problem because after initializing the empty index e.g. the
`cache_tree` in that index could have been initialized before a
subsequent call to `do_read_index()` wants to ensure an initialized
index. And if that subsequent call mistakes the index not to have been
initialized, it would lead to leaked memory.
The correct fix for that memory leak is to adjust the condition so that
it does not mistake `active_nr == 0` to mean that the index has not yet
been read.
Using the `initialized` flag instead, we avoid that mistake, and as a
bonus we can fix a bug at the same time that was introduced by the
memory leak fix: When deleting all tracked files and then asking `git
commit -a -m ...` to commit the result, Git would internally update the
index, then discard and re-read the index undoing the update, and fail
to commit anything.

Call diff_free() on the "pruning" member of "struct rev_info". Doing
so makes several tests pass under SANITIZE=leak.
This was also the last missing piece that allows us to remove the
UNLEAK() in "cmd_diff" and "cmd_diff_index", which allows us to use
those commands as a canary for general leaks in the revisions API. See
[1] for further rationale, and 886e1084d78 (builtin/: add UNLEAKs,
2017-10-01) for the commit that added the UNLEAK() there.

Change some of the patterns in the test suite where we were hiding the
exit code from "git" by invoking it in a sub-shell within a "test"
expression to use temporary files and test_cmp instead.
These are not all the occurrences of this anti-pattern, but these in
particular hid issues where LSAN was dying, and I'd thus marked these
tests as passing under the linux-leaks CI job in past commits with
"TEST_PASSES_SANITIZE_LEAK=true". Let's deal with that by either
removing that marking, or skipping specific tests under
!SANITIZE_LEAK.

Failures within `for` and `while` loops can go unnoticed if not detected
and signaled manually since the loop itself does not abort when a
contained command fails, nor will a failure necessarily be detected when
the loop finishes since the loop returns the exit code of the last
command it ran on the final iteration, which may not be the command
which failed. Therefore, detect and signal failures manually within
loops using the idiom `|| return 1` (or `|| exit 1` within subshells).

The top-level &&-chain checker built into t/test-lib.sh causes tests to
magically exit with code 117 if the &&-chain is broken. However, it has
the shortcoming that the magic does not work within `{...}` groups,
`(...)` subshells, `$(...)` substitutions, or within bodies of compound
statements, such as `if`, `for`, `while`, `case`, etc. `chainlint.sed`
partly fills in the gap by catching broken &&-chains in `(...)`
subshells, but bugs can still lurk behind broken &&-chains in the other
cases.
Fix broken &&-chains in `{...}` groups in order to reduce the number of

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'.

Since Git 2.0, "add -u" and "add -A" run from a subdirectory without
any pathspec mean "everything in the working tree" (before 2.0, they
were limited to the current directory). The limiting to the current
directory was implemented by inserting "." to the command line when
the end user did not give us any pathspec. At 2.0, we updated the
code to insert ":/" (instead of '.') to consider everything from the
top-level, by using a pathspec magic "top".
The call to parse_pathspec() using the command line arguments is,
however, made with PATHSPEC_PREFER_FULL option since 5a76aff1 (add:
convert to use parse_pathspec, 2013-07-14), which predates Git 2.0.
In retrospect, there was no need to turn "adding . to limit to the
directory" into "adding :/ to unlimit to everywhere" in Git 2.0;
instead we could just have done "if there is no pathspec on the
command line, just let it be". The parse_pathspec() then would give
us a pathspec that matches everything and all is well.
Incidentally such a simplification also fixes a corner case bug that
stems from the fact that ":/" does not necessarily mean any magic.
A user would say "git --literal-pathspecs add -u :/" from the
command line when she has a directory ':' and wants to add
everything in it (and she knows that her :/ will be taken as
'everything under the sun' magic pathspec unless she disables the
magic with --literal-pathspecs). The internal use of ':/' would
behave the same way as such an explicitly given ":/" when run with
"--literal-pathspecs", and will not add everything under the sun as
the code originally intended.

There are many instances where the treatment of symbolic links in the
object model and the algorithms are tested, but where it is not
necessary to actually have a symbolic link in the worktree. Make
adjustments to the tests and remove the SYMLINKS prerequisite when
appropriate in trivial cases, where "trivial" means:
- merely a replacement of 'ln -s a b && git add b' by test_ln_s_add
is needed;
- a test for symbolic link on the file system can be split off (and
remains protected by SYMLINKS);
- existing code is equivalent to test_ln_s_add.

git add: rework the logic to warn "git add <pathspec>..." default change
git add: start preparing for "git add <pathspec>..." to default to "-A"

When "git add subdir/" is run without "-u" or "-A" option, e.g.
$ edit subdir/x
$ create subdir/y
$ rm subdir/z
$ git add subdir/
the command does not notice removal of paths (e.g. subdir/z) from
the working tree. This sometimes confuses new people, as arguably
"git add" is told to record the current state of "subdir/" as a
whole, not the current state of the paths that exist in the working
tree that matches that pathspec (the latter by definition excludes
the state of "subdir/z" because it does not exist in the working
tree).
Plan to eventually make "git add" pretend as if "-A" is given when
there is a pathspec on the command line. When resolving a conflict
to remove a path, the current code tells you to "git rm $path", but
with such a change, you will be able to say "git add $path" (of
course you can do "git add -A $path" today). That means that we can
simplify the advice messages given by "git status". That all will
be in Git 2.0 or later, if we are going to do so.
For that transition to work, people need to learn either to say "git
add --no-all subdir/" when they want to ignore the removed paths
like "subdir/z", or to say "git add -A subdir/" when they want to
take the state of the directory as a whole.
"git add" without any argument will continue to be a no-op.

* jc/fix-add-u-unmerged:
Fix "add -u" that sometimes fails to resolve unmerged paths
|
|
"git add -u" updates the index with the updated contents from the working
tree by internally running "diff-files" to grab the set of paths that are
different from the index. Then it updates the index entries for the paths
that are modified in the working tree, and deletes the index entries for
the paths that are deleted in the working tree.
It ignored the output from the diff-files that indicated that a path is
unmerged. For these paths, it instead relied on the fact that an unmerged
path is followed by the result of comparison between stage #2 (ours) and
the working tree, and used that to update or delete such a path when it is
used to record the resolution of a conflict.
As the result, when a path did not have stage #2 (e.g. "we deleted while
the other side added"), these unmerged stages were left behind, instead of
recording what the user resolved in the working tree.
Since we recently fixed "diff-files" to indicate if the corresponding path
exists on the working tree for an unmerged path, we do not have to rely on
the comparison with stage #2 anymore. We can instead tell the diff-files
not to compare with higher stages, and use the unmerged output to update
the index to reflect the state of the working tree.
The changes to the test vector in t2200 illustrates the nature of the bug
and the fix. The test expected stage #1 and #3 entries be left behind,
but it was codifying the buggy behaviour.

Many tests depend on that symbolic links work. This introduces a check
that sets the prerequisite tag SYMLINKS if the file system supports
symbolic links. Since so many tests have to check for this prerequisite,
we do the check in test-lib.sh, so that we don't need to repeat the test
in many scripts.
To check for 'ln -s' failures, you can use a FAT partition on Linux:
$ mkdosfs -C git-on-fat 1000000
$ sudo mount -o loop,uid=j6t,gid=users,shortname=winnt git-on-fat /mnt
Clone git to /mnt and
$ GIT_SKIP_TESTS='t0001.1[34] t0010 t1301 t403[34] t4129.[47] t5701.7
t7701.3 t9100 t9101.26 t9119 t9124.[67] t9200.10 t9600.6' \

Linux does not provide.)

On Windows, there is an unfortunate interaction between the MSYS bash and
git's command line processing:
- Since Windows's CMD does not do the wildcard expansion, but passes
arguments like path* through to the programs, the programs must do the
expansion themselves. This happens in the startup code before main() is
entered.
- bash, however, passes the argument "path*" to git, assuming that git will
see the unquoted word unchanged as a single argument.
But actually git expands the unquoted word before main() is entered.
In t2200, not all names that the test case is interested in exist as files
at the time when 'git ls-files' is invoked. git expands "path?" to only
the subset of files the exist, and only that subset was listed, so that the
test failed. We now list all interesting paths explicitly.
In t7004, git exanded the pattern "*a*" to "actual" (the file that stdout
was redirected to), which is not what the was tested for. We fix it by
renaming the output file (and removing any existing files matching *a*).
This was originally fixed by Johannes Schindelin.

After you resolve a conflicted merge to remove the path, "git add -u"

Many scripts compare actual and expected output using
"diff -u". This is nicer than "cmp" because the output shows
how the two differ. However, not all versions of diff
understand -u, leading to unnecessary test failure.
This adds a test_cmp function to the test scripts and
switches all "diff -u" invocations to use it. The function
uses the contents of "$GIT_TEST_CMP" to compare its
arguments; the default is "diff -u".
On systems with a less-capable diff, you can do:
