16d4bd4f14 leak tests: mark some diff tests as passing with SANITIZE=leak
Mark some tests that match "*diff*" as passing when git is compiled
with SANITIZE=leak. They'll now be listed as running under the
"GIT_TEST_PASSING_SANITIZE_LEAK=true" test mode (the "linux-leaks" CI
target).

ebd73f50c6 test libs: rename "diff-lib" to "lib-diff"
Rename the "diff-lib" to "lib-diff". With this rename and preceding
commits there is no remaining t/*lib* which doesn't follow the
convention of being called t/lib-*.

0940e5f211 diffcore-rename: properly honor the difference between -M and -C
We would allow rename detection to do copy detection even when asked
purely for renames.  That confuses users, but more importantly it can
terminally confuse the recursive merge rename logic.

f6c1998f14 t/t4004-diff-rename-symlink.sh: use three-arg <prereq>
Change the tests that skipped due to unavailable SYMLINKS support to
use the three-arg prereq form of test_expect_success.

This is like the "tests: implicitly skip SYMLINKS tests using
<prereq>" change, but I needed to create an additional test for some
setup code. It's in a separate change as suggested by Jonathan Nieder
for ease of reviewing.

    Probably belongs in a separate patch.  More importantly, it is missing
    &&-chaining (not a regression, but it is best to set a good example).

fadb5156e4 tests: Skip tests in a way that makes sense under TAP
SKIP messages are now part of the TAP plan. A TAP harness now knows
why a particular test was skipped and can report that information. The
non-TAP harness built into Git's test-lib did nothing special with
these messages, and is unaffected by these changes.

704a3143d5 Use prerequisite tags to skip tests that depend on symbolic links
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' \
        make test

(These additionally skipped tests depend on POSIX permissions that FAT on
Linux does not provide.)

bfdbee9810 tests: use $TEST_DIRECTORY to refer to the t/ directory
Many test scripts assumed that they will start in a 'trash' subdirectory
that is a single level down from the t/ directory, and referred to their
test vector files by asking for files like "../t9999/expect".  This will
break if we move the 'trash' subdirectory elsewhere.

To solve this, we earlier introduced "$TEST_DIRECTORY" so that they can
refer to t/ directory reliably.  This finally makes all the tests use
it to refer to the outside environment.

With this patch, and a one-liner not included here (because it would
contradict with what Dscho really wants to do):

| diff --git a/t/test-lib.sh b/t/test-lib.sh
| index 70ea7e0..60e69e4 100644
| --- a/t/test-lib.sh

all the tests still pass, but we would want extra sets of eyeballs on this
type of change to really make sure.

ec1fcc16af Show original and resulting blob object info in diff output.
This adds more cruft to diff --git header to record the blob SHA1 and
the mode the patch/diff is intended to be applied against, to help the
receiving end fall back on a three-way merge.  The new header looks
like this:

    diff --git a/apply.c b/apply.c
    index 7be5041..8366082 100644
    --- a/apply.c
    +++ b/apply.c

     //  --stat does just a diffstat, and doesn't actually apply
    +//  --show-index-info shows the old and new index info for...
    ...

Upon receiving such a patch, if the patch did not apply cleanly to the
target tree, the recipient can try to find the matching old objects in
her object database and create a temporary tree, apply the patch to
that temporary tree, and attempt a 3-way merge between the patched
temporary tree and the target tree using the original temporary tree
as the common ancestor.

The patch lifts the code to compute the hash for an on-filesystem
object from update-index.c and makes it available to the diff output
routine.

215a7ad1ef Big tool rename.
As promised, this is the "big tool rename" patch.  The primary differences
since 0.99.6 are:

  (1) git-*-script are no more.  The commands installed do not
      have any such suffix so users do not have to remember if
      something is implemented as a shell script or not.

  (2) Many command names with 'cache' in them are renamed with
      'index' if that is what they mean.

There are backward compatibility symblic links so that you and
Porcelains can keep using the old names, but the backward
compatibility support  is expected to be removed in the near
future.

2bbcddee87 Adjust diff-raw tests to the status letter change.
We use 'A' for added files instead of 'N' to make the it
visually easier to distinguish from 'M' now.

While we are at it, make the test scripts executable.  Yes, I
know it does not matter because t/Makefile runs them explicitly
with "sh tXXXX-blah.sh", but being consistent is always better.

dc93841715 diff 'rename' format change.
Clearly even Junio felt git "rename" header lines should say "from/to"
instead of "old/new", since he wrote the documentation that way.

This way it also matches "copy".

git-apply will accept both versions, at least for a while.

25d5ea410f [PATCH] Redo rename/copy detection logic.
Earlier implementation had a major screw-up in the memory
management area.  Rename/copy logic sometimes borrowed a pointer
to a structure without any provision for downstream to determine
which pointer is shared and which is not.  This resulted in the
later clean-up code to sometimes double free such structure,
resulting in a segfault.  This made -M and -C useless.

Another problem the earlier implementation had was that it
reordered the patches, and forced the logic to differentiate
renames and copies to depend on that particular order.  This
problem was fixed by teaching rename/copy detection logic not to
do any reordering, and rename-copy differentiator not to depend
on the order of the patches.  The diffs will leave rename/copy
detector in the same destination path order as the patch that
was fed into it.  Some test vectors have been reordered to
accommodate this change.

It also adds a sanity check logic to the human-readable diff-raw
output to detect paths with embedded TAB and LF characters,
which cannot be expressed with that format.  This idea came up
during a discussion with Chris Wedgwood.

60896c7bfe [PATCH] Be careful with symlinks when detecting renames and copies.
Earlier round was not treating symbolic links carefully enough,
and would have produced diff output that renamed/copied then
edited the contents of a symbolic link, which made no practical
sense.  Change it to detect only pure renames.
