t7800: run --dir-diff tests with and without symlinks
Currently the difftool --dir-diff tests may or may not use symlinks
depending on the operating system on which they are run. In one case
this has caused a test failure to be noticed only on Windows when the
test also fails on Linux when difftool is invoked with --no-symlinks.
Rewrite these tests so that they do not depend on the environment but
run explicitly with both --symlinks and --no-symlinks, protecting the
--symlinks version with a SYMLINKS prerequisite.

When 'git difftool --dir-diff' is using --no-symlinks (either explicitly
or implicitly because it's running on Windows), any working tree files
that have been copied to the temporary directory are copied back after
the difftool completes.
Because an earlier test uses "git add .", the "output" file used by
tests is tracked by Git and the following sequence occurs during some
tests:
1) the shell opens "output" to redirect the difftool output
2) difftool copies the empty "output" to the temporary directory
3) difftool runs "ls" which writes to "output"
4) difftool copies the empty "output" file back over the output of the
command
5) the output file doesn't contain the expected output, causing the
test to fail
Instead of adding all changes, explicitly add only the files that the
test is using, allowing later tests to write their result files into the
working tree.

After running the user's diff tool, git-difftool will copy any files
that differ between the working tree and the temporary tree. This is
useful when the user edits the file in their diff tool but is wrong if
they edit the working tree file while examining the diff.
Instead of copying unconditionally when the files differ, create and
index from the working tree files and only copy the temporary file back
if it was modified and the working tree file was not. If both files
have been modified, print a warning and exit with an error.
Note that we cannot use an existing index in git-difftool since those
contain the modified files that need to be checked out but here we are
looking at those files which are copied from the working tree and not
checked out. These are precisely the files which are not in the
existing indices.

t1300: document some aesthetic failures of the config editor
The config-editing code used by "git config var value" is
built around the regular config callback parser, whose only
triggerable item is an actual key. As a result, it does not
know anything about section headers, which can result in
unnecessarily ugly output:
1. When we delete the last key in a section, we should be
able to delete the section header.
2. When we add a key into a section, we should be able to
reuse the same section header, even if that section did
not have any keys in it already.
Unfortunately, fixing these is not trivial with the current
code. It would involve the config parser recording and
passing back information on each item it finds, including
headers, keys, and even comments (or even better, generating
an actual in-memory parse-tree).
Since these behaviors do not cause any functional problems
(i.e., the resulting config parses as expected, it is just
uglier than one would like), fixing them can wait until
somebody feels like substantially refactoring the parsing
code. In the meantime, let's document them as known issues
with some tests.

the resulting archive would contain only "foo" and ".gitattributes",
not subdir. This was broken with a recent change that intended to
allow "subdir/ export-ignore" to also exclude the directory, but
instead ended up _requiring_ the trailing slash by mistake.
A pattern "subdir" should match any path "subdir", whether it is a
directory or a non-directory. A pattern "subdir/" insists that a
path "subdir" must be a directory for it to match.
This patch adds test not just for this simple case, but also for
deeper cross-directory cases, as well as cases with wildcards.

dir.c::match_pathname(): pay attention to the length of string parameters
This function takes two counted strings: a <pattern, patternlen> pair
and a <pathname, pathlen> pair. But we end up feeding the result to
fnmatch, which expects NUL-terminated strings.
We can fix this by calling the fnmatch_icase_mem function, which
handles re-allocating into a NUL-terminated string if necessary.
While we're at it, we can avoid even calling fnmatch in some cases. In
addition to patternlen, we get "prefix", the size of the pattern that
contains no wildcard characters. We do a straight match of the prefix
part first, and then use fnmatch to cover the rest. But if there are
no wildcards in the pattern at all, we do not even need to call
fnmatch; we would simply be comparing two empty strings.

dir.c::match_pathname(): adjust patternlen when shifting pattern
If we receive a pattern that starts with "/", we shift it
forward to avoid looking at the "/" part. Since the prefix
and patternlen parameters are counts of what is in the
pattern, we must decrement them as we increment the pointer.
We remembered to handle prefix, but not patternlen. This
didn't cause any bugs, though, because the patternlen
parameter is not actually used. Since it will be used in
future patches, let's correct this oversight.

dir.c::match_basename(): pay attention to the length of string parameters
The function takes two counted strings (<basename, basenamelen> and
<pattern, patternlen>) as parameters, together with prefix (the
length of the prefix in pattern that is to be matched literally
without globbing against the basename) and EXC_* flags that tells it
how to match the pattern against the basename.
However, it did not pay attention to the length of these counted
strings. Update them to do the following:
* When the entire pattern is to be matched literally, the pattern
matches the basename only when the lengths of them are the same,
and they match up to that length.
* When the pattern is "*" followed by a string to be matched
literally, make sure that the basenamelen is equal or longer than
the "literal" part of the pattern, and the tail of the basename
string matches that literal part.
* Otherwise, use the new fnmatch_icase_mem helper to make
sure we only lookmake sure we use only look at the
counted part of the strings. Because these counted strings are
full strings most of the time, we check for termination
to avoid unnecessary allocation.

attr.c::path_matches(): special case paths that end with a slash
The function is given a string that ends with a slash to signal that
the path is a directory to make sure that a pattern that ends with a
slash (i.e. MUSTBEDIR) can tell directories and non-directories
apart. However, the pattern itself (pat->pattern and
pat->patternlen) that came from such a MUSTBEDIR pattern is
represented as a string that ends with a slash, but patternlen does
not count that trailing slash. A MUSTBEDIR pattern "element/" is
represented as a counted string <"element/", 7> and this must match
match pathname "element/".
Because match_basename() and match_pathname() want to see pathname
"element" to match against the pattern <"element/", 7>, reduce the
length of the path to exclude the trailing slash when calling
these functions.

git-difftool(1): fix formatting of --symlink description
If you run a log with diffs (such as -p, --raw, --stat etc.) the
current code ends up loading many objects twice. For example, for
'log -3000 -p' my instrumentation said the objects loaded more than
once are distributed as follows:
2008 blob
2103 commit
2678 tree
Fixing blobs and trees will be harder, because those are really used
within the diff engine and need some form of caching.
However, fixing the commits is easy at least at the band-aid level.
They are triggered by log_tree_diff() invoking diff_tree_sha1() on
commits, which duly loads the specified object to dereference it to a
tree. Since log_tree_diff() knows that it works with commits and they
must have trees, we can simply pass through the trees.
We add some parse_commit() calls. The ones for the parents are
required; we do not know at this stage if they have been looked at.
The one for the commit itself is pure paranoia, but has about the same
cost as an assertion on commit->object.parsed.
This has a quite dramatic effect on log --raw, though only a
negligible impact on log -p:

- for all updated items, call match_pathspec
- for all items, call match_pathspec (inside unmerge_cache)
- for all items, call match_pathspec (for showing "path .. is unmerged)
- for updated items, call match_pathspec and update paths
That's a lot of duplicate match_pathspec(s) and the function is not
exactly cheap to be called so many times, especially on large indexes.
This patch makes it call match_pathspec once per updated index entry,
save the result in ce_flags and reuse the results in the following
loops.
The changes in 0a1283b (checkout $tree $path: do not clobber local
changes in $path not in $tree - 2011-09-30) limit the affected paths
to ones we read from $tree. We do not do anything to other modified
entries in this case, so the "for all items" above could be modified
to "for all updated items". But..
The command's behavior now is modified slightly: unmerged entries that
match $path, but not updated by $tree, are now NOT touched. Although
this should be considered a bug fix, not a regression. A new test is
added for this change.
And while at there, free ps_matched after use.
The following command is tested on webkit, 215k entries. The pattern
is chosen mainly to make match_pathspec sweat:

When core.sharedRepository is used, set_shared_perm() in path.c
needs lstat() to return the correct POSIX permissions.
The default for cygwin is core.ignoreCygwinFSTricks = false, which
means that the fast implementation in do_stat() is used instead of
lstat().
lstat() under cygwin uses the Windows security model to implement
POSIX-like permissions. The user, group or everyone bits can be set
individually.
do_stat() simplifes the file permission bits, and may return a wrong
value. The read-only attribute of a file is used to calculate the
permissions, resulting in either rw-r--r-- or r--r--r--
One effect of the simplified do_stat() is that t1301 fails.
Add a function cygwin_get_st_mode_bits() which returns the POSIX
permissions. When not compiling for cygwin, true_mode_bits() in
path.c is used.
Side note:
t1301 passes under cygwin 1.5.
The "user write" bit is synchronized with the "read only" attribute
of a file:
$ chmod 444 x
$ attrib x
A R C:\temp\pt\x
cygwin 1.7 would show
