e172755b1e upload-pack: fix transfer.hiderefs over smart-http
When upload-pack advertises the refs (either for a normal,
non-stateless request, or for the initial contact in a
stateless one), we call for_each_ref with the send_ref
function as its callback. send_ref, in turn, calls
mark_our_ref, which checks whether the ref is hidden, and
sets OUR_REF or HIDDEN_REF on the object as appropriate.  If
it is hidden, mark_our_ref also returns "1" to signal
send_ref that the ref should not be advertised.

If we are not advertising refs, (i.e., the follow-up
invocation by an http client to send its "want" lines), we
use mark_our_ref directly as a callback to for_each_ref. Its
marking does the right thing, but when it then returns "1"
to for_each_ref, the latter interprets this as an error and
stops iterating. As a result, we skip marking all of the
refs that come lexicographically after it. Any "want" lines
from the client asking for those objects will fail, as they
were not properly marked with OUR_REF.

To solve this, we introduce a wrapper callback around
mark_our_ref which always returns 0 (even if the ref is
hidden, we want to keep iterating). We also tweak the
signature of mark_our_ref to exclude unnecessary parameters
that were present only to conform to the callback interface.
This should make it less likely for somebody to accidentally
use it as a callback in the future.

5ee875852e log --decorate: do not leak "commit" color into the next item
In "git log --decorate", you would see the commit header like this:

    commit ... (HEAD, jc/decorate-leaky-separator-color)

where "commit ... (" is painted in color.diff.commit, "HEAD" in
color.decorate.head, ", " in color.diff.commit, the branch name in
color.decorate.branch and then closing ")" in color.diff.commit.

If you wanted to paint the HEAD and local branch name in the same
color as the body text (perhaps because cyan and green are too faint
on a black-on-white terminal to be readable), you would not want to
have to say

    [color "decorate"]
        head = black
        branch = black

because that you would not be able to reuse same configuration on a
white-on-black terminal.  You would naively expect

    [color "decorate"]
        head = normal
	branch = normal

to work, but unfortunately it does not.  It paints the string "HEAD"
and the branch name in the same color as the opening parenthesis or
comma between the decoration elements.  This is because the code
forgets to reset the color after printing the "prefix" in its own
color.

It theoretically is possible that some people were expecting and
relying on that the attribute set as the "diff.commit" color, which
is used to draw these opening parenthesis and inter-item comma, is
inherited by the drawing of branch names, but it is not how the
coloring works everywhere else.

ab27389aff diff --shortstat --dirstat: remove duplicate output
When --shortstat is used in conjunction with --dirstat=changes, git diff will
output the dirstat information twice: first as calculated by the 'lines'
algorithm, then as calculated by the 'changes' algorithm:

    $ git diff --dirstat=changes,10 --shortstat v2.2.0..v2.2.1
     23 files changed, 453 insertions(+), 54 deletions(-)

      26.2% t/
      46.6% Documentation/RelNotes/
      16.6% t/

The same duplication happens for --shortstat together with --dirstat=files, but
not for --shortstat together with --dirstat=lines.

Limit output to only include one dirstat part, calculated as specified
by the --dirstat parameter. Also, add test for this.

4d6be03b95 diffcore-rename: avoid processing duplicate destinations
The rename code cannot handle an input where we have
duplicate destinations (i.e., more than one diff_filepair in
the queue with the same string in its pair->two->path). We
end up allocating only one slot in the rename_dst mapping.
If we fill in the diff_filepair for that slot, when we
re-queue the results, we may queue that filepair multiple
times. When the diff is finally flushed, the filepair is
processed and free()d multiple times, leading to heap
corruption.

This situation should only happen when a tree diff sees
duplicates in one of the trees (see the added test for a
detailed example). Rather than handle it, the sanest thing
is just to turn off rename detection altogether for the
diff.

817d03e105 test_ln_s_add: refresh stat info of fake symbolic links
We have a helper function test_ln_s_add that inserts a symbolic link
into the index even if the file system does not support symbolic links.
There is a small flaw in the emulation path: the added entry does not
pick up stat information of the fake symbolic link from the file system,
as a consequence, the index is not exactly the same as for the "regular"
path (where symbolic links are available). To fix this, just call
git update-index again.

This flaw was revealed by the earlier change that tightened
compare_diff_raw(), because a test case in t4008 depends on the
correctly updated index.

The ssh:// syntax was added in 2386d658 (Add first cut at "git
protocol" connect logic., 2005-07-13), it accepted
ssh://user@2001:db8::1/repo.git, which is now legacy.

Over the years the parser was improved to support [] and port numbers,
but the combination of ssh://user@[2001:db8::1]:222/repo.git did
never work.

The only only way to use a user name, a literall IPV6 address and a port
number was ssh://[user@2001:db8::1]:222/repo.git

(Thanks to Christian Taube <lists@hcf.yourweb.de> for reporting this long
standing issue)

New users would use ssh://user@[2001:db8::1]:222/repo.git,
so change the parser to handle it correctly.

and avoid regressions for users which upgrade an existing installation

b485373052 daemon: sanitize incoming virtual hostname
We use the daemon_avoid_alias function to make sure that the
pathname the user gives us is sane. However, after applying
that check, we might then interpolate the path using a
string given by the server admin, but which may contain more
untrusted data from the client. We should be sure to
sanitize this data, as well.

We cannot use daemon_avoid_alias here, as it is more strict
than we need in requiring a leading '/'. At the same time,
we can be much more strict here. We are interpreting a
hostname, which should not contain slashes or excessive runs
of dots, as those things are not allowed in DNS names.

Note that in addition to cleansing the hostname field, we
must check the "canonical hostname" (%CH) as well as the
port (%P), which we take as a raw string.  For the canonical
hostname, this comes from an actual DNS lookup on the
accessed IP, which makes it a much less likely vector for
problems. But it does not hurt to sanitize it in the same
way. Unfortunately we cannot test this case easily, as it
would involve a custom hostname lookup.

We do not need to check %IP, as it comes straight from
inet_ntop, so must have a sane form.

db7b9e3ad3 t4008: modernise style
Update this ancient test script to a more modern style in which the
expected result is prepared inside the body of the test that uses
it.  Also, instead of using $tree, a shell variable, throughout the
test script, create a tag that points at it, to make it easier to
manually debug the test script in its trash directory.

bd9150b7e5 t/diff-lib: check exact object names in compare_diff_raw
The "sanitize" helper wanted to strip the similarity and
dissimilarity scores when making comparison, but it was
stripping away the object names as well.

While we do not want to require the exact object names the tests
expect to be maintained, as it would be seen as an extra burden,
this would have prevented us catching a silly bug such as showing
non 0{40} object name on the preimage side of an addition or on the
postimage side of a deletion, because all [0-9a-f]{40} strings were
considered equally OK.

In the longer term, when a test only wants to see the status of the
change without having to worry about object names, it should be
rewritten not to inspect the raw format.

459b8d22e5 tests: do not borrow from COPYING and README from the real source
These two files have been modified since the tests started using
as test input, making the exact object names they expect to be
different from what actually happens in the trash repository they
use to run tests.

Instead, take a snapshot of these two files and keep them in
t/diff-lib/ so that we can update the real ones without having to
worry about breaking tests.

bb8db1b553 t4010: correct expected object names
The output the test expects is bogus.

It was left unnoticed only because compare_diff_raw, which only
cares about the add/delete/rename/copy was used to check the result.

2c0ab4d49d t9300: correct expected object names
The output the test  expects is bogus.  There are no blob objects
whose names are 36a590... or 046d037... when this test was run.

It was left unnoticed only because compare_diff_raw, which only
cares about the add/delete/rename/copy was used to check the result.

f2b4f0a23b t4008: correct stale comments
A complete rewrite of a single file was originally designed to be
expressed as a deletion immediately followed by a creation of the
same file, and the comments in the test updated here were written to
reflect that design decision made in f345b0a0 (Add -B flag to diff-*
brothers., 2005-05-30).  However, we later realized that a complete
rewrite is merely how a textual diff should be represented at
366175ef (Rework -B output., 2005-06-19), and updated the actual
tests.  But we forgot to update the introductory text while doing
so.

204a8ffe67 merge-file: correctly open files when in a subdir
run_setup_gently() is called before merge-file. This may result in changing
current working directory, which wasn't taken into account when opening a file
for writing.

Fix by prepending the passed prefix. Previous var is left so that error
messages keep referring to the file from the user's working directory
perspective.

e0d201b616 apply: do not touch a file beyond a symbolic link
Because Git tracks symbolic links as symbolic links, a path that
has a symbolic link in its leading part (e.g. path/to/dir/file,
where path/to/dir is a symbolic link to somewhere else, be it
inside or outside the working tree) can never appear in a patch
that validly applies, unless the same patch first removes the
symbolic link to allow a directory to be created there.

Detect and reject such a patch.

Things to note:

 - Unfortunately, we cannot reuse the has_symlink_leading_path()
   from dir.c, as that is only about the working tree, but "git
   apply" can be told to apply the patch only to the index or to
   both the index and to the working tree.

 - We cannot directly use has_symlink_leading_path() even when we
   are applying only to the working tree, as an early patch of a
   valid input may remove a symbolic link path/to/dir and then a
   later patch of the input may create a path path/to/dir/file, but
   "git apply" first checks the input without touching either the
   index or the working tree.  The leading symbolic link check must
   be done on the interim result we compute in-core (i.e. after the
   first patch, there is no path/to/dir symbolic link and it is
   perfectly valid to create path/to/dir/file).

   Similarly, when an input creates a symbolic link path/to/dir and
   then creates a file path/to/dir/file, we need to flag it as an
   error without actually creating path/to/dir symbolic link in the
   filesystem.

Instead, for any patch in the input that leaves a path (i.e. a non
deletion) in the result, we check all leading paths against the
resulting tree that the patch would create by inspecting all the
patches in the input and then the target of patch application
(either the index or the working tree).

This way, we catch a mischief or a mistake to add a symbolic link
path/to/dir and a file path/to/dir/file at the same time, while
allowing a valid patch that removes a symbolic link path/to/dir and
then adds a file path/to/dir/file.
