The "--head" option to "git show-ref" was only to add "HEAD" to the

meaning of the option to always show "HEAD" regardless of what
filtering will be applied to any other ref (this is a backward

cygwin: stop forcing core.filemode=false

We force core.filemode=false since c869753e (Force core.filemode to
false on Cygwin., 2006-12-30), even when the repository is on a
filesystem on which Cygwin can give us trustable filemodes, because
many native Windows applications the users use to edit files in the
working tree tend to (re)create files with executable bit randomly
set or reset. However, binary distribution of Git that is supplied
by the downstream project to its users has been built without this
consideration.

Drop NO_TRUSTABLE_FILEMODE from our default configuration so that
hand-compiled Git out of box will match theirs.

The purpose of git-contacts is to determine a list of people who might
have some interest in a patch or set of changes. It can be used as
git-send-email's --cc-cmd argument or the computed list might be used to
ask for comments on a proposed change. As such, it is important to
report up-to-date email addresses in the computed list rather than
potentially outdated ones recorded with commits. Apply git's mailmap
functionality to the retrieved contacts in order to achieve this goal.

contrib: add git-contacts helper

This script lists people that might be interested in a patch by going
back through the history for each patch hunk, and finding people that
reviewed, acknowledged, signed, authored, or were Cc:'d on the code the
patch is modifying.

It does this by running git-blame incrementally on each hunk and then
parsing the commit message. After gathering all participants, it
determines each person's relevance by considering how many commits
mentioned that person compared with the total number of commits under
consideration. The final output consists only of participants who pass a
minimum threshold of participation.

Several conditions controlling a person's significance are currently
hard-coded, such as minimum participation level, blame date-limiting,
and -C level for detecting moved and copied lines. In the future, these
conditions may become configurable.

For example:

% git contacts 0001-remote-hg-trivial-cleanups.patch
Felipe Contreras <felipe.contreras@gmail.com>
Jeff King <peff@peff.net>
Max Horn <max@quendi.de>
Junio C Hamano <gitster@pobox.com>

Thus, it can be invoked as git-send-email's --cc-cmd option, among other
possible uses.

This is a Perl rewrite of Felipe Contreras' git-related patch series[1]
written in Ruby.

POSIX explicitly states "the [environ] variable, which

traverse_trees(): clarify return value of the callbackStefan Beller Fri, 19 Jul 2013 20:26:32 +0000 (22:26 +0200)

traverse_trees(): clarify return value of the callback

The variable name "ret" sounds like the variable to be returned, but
since e6c111b4 we return error, and it is misleading.

As this variable tells us which trees in t[] array were used in the
callback function, so that this caller can know the entries in which
of the trees need advancing, "trees_used" is a better name.

Also the assignment to 0 was removed at the start of the function as
well after the "if (interesting)" block. Those are unneeded as that
variable is set to the callback return value any time we enter the
"if (interesting)" block, so we'd overwrite old values anyway.

git add -e: Explicitly specify that patch should have no color

After 4c7f1819 (make color.ui default to 'auto', 2013-06-10), the
patch file to be edited during 'git add -e' receives all the color
codes. This is because diffopt.use_color defaults to -1, which
causes want_color to now return 'auto'.

By explicitly setting use_color to 0, we can ensure the diff output
has no color codes in it.

Git.pm: revert _temp_cache use of temp_is_locked

When the temp_is_locked function was introduced, there was
a desire to make _temp_cache use it. Unfortunately due to the
various tests and logic flow involved changing the _temp_cache
function to use the new temp_is_locked function is problematic
as _temp_cache needs a slightly different test than is provided
by the temp_is_locked function.

This change reverts use of temp_is_locked in the _temp_cache
function and restores the original code that existed there
before the temp_is_locked function was added.

send-email: be explicit with SSL certificate verification

When initiating an SSL connection without explicitly specifying the
SSL certificate verification mode, Net::SMTP::SSL defaults to no
verification, but recent versions of the module gives a warning
against this use of the default.

Enable certificate verification by default, using /etc/ssl/certs as
the default path for certificates of certificate authorities. This
path can be overriden by the --smtp-ssl-cert-path command line
option and the sendemail.smtpSSLCertPath configuration variable.

Passing an empty string as the path for CA certificates path disables
the SSL certificate verification explicitly, which does not trigger
the warning from recent versions of Net::SMTP::SSL.

describe: fix --contains when a tag is given as inputJunio C Hamano Thu, 18 Jul 2013 21:46:51 +0000 (14:46 -0700)

describe: fix --contains when a tag is given as input

"git describe" takes a commit and gives it a name based on tags in
its neighbourhood. The command does take a commit-ish but when
given a tag that points at a commit, it should dereference the tag
before computing the name for the commit.

As the whole processing is internally delegated to name-rev, if we
unwrap tags down to the underlying commit when invoking name-rev, it
will make the name-rev issue an error message based on the unwrapped
object name (i.e. either 40-hex object name, or "$tag^0") that is
different from what the end-user gave to the command when the commit
cannot be described. Introduce an internal option --peel-tag to the
name-rev to tell it to unwrap a tag in its input from the command
line.

name-rev: differentiate between tags and commits they point at

"git name-rev --stdin" has been fixed to convert an object name that
points at a tag to a refname of the tag. The codepath to handle its
command line arguments, however, fed the commit that the tag points
at to the underlying naming machinery.

With this fix, you will get this:

$ git name-rev --refs=tags/\* --name-only $(git rev-parse v1.8.3 v1.8.3^0)
v1.8.3
v1.8.3^0

which is the same as what you would get from the fixed "--stdin" variant:

$ git rev-parse v1.8.3 v1.8.3^0 | git name-rev --refs=tags/\* --name-only

There are only four (with some generous rounding) instances in the
current source code where we speak of "subproject" instead of
"submodule". They are as follows:

* one error message in git-apply and two in entry.c

* the patch format for submodule changes

The latter was introduced in 0478675 (Expose subprojects as special
files to "git diff" machinery, 2007-04-15), apparently before the
terminology was settled. We can of course not change the patch
format.

cygwin: Remove the Win32 l/stat() implementation

Commit adbc0b6b ("cygwin: Use native Win32 API for stat", 30-09-2008)
added a Win32 specific implementation of the stat functions. In order
to handle absolute paths, cygwin mount points and symbolic links, this
implementation may fall back on the standard cygwin l/stat() functions.
Also, the choice of cygwin or Win32 functions is made lazily (by the
first call(s) to l/stat) based on the state of some config variables.

Unfortunately, this "schizophrenic stat" implementation has been the
source of many problems ever since. For example, see commits 7faee6b8,
79748439, 452993c2, 085479e7, b8a97333, 924aaf3e, 05bab3ea and 0117c2f0.

In order to avoid further problems, such as the issue raised by the new
reference handling API, remove the Win32 l/stat() implementation.

do_one_ref(): save and restore value of current_refMichael Haggerty Mon, 15 Jul 2013 15:24:17 +0000 (17:24 +0200)

do_one_ref(): save and restore value of current_ref

If do_one_ref() is called recursively, then the inner call should not
permanently overwrite the value stored in current_ref by the outer
call. Aside from the tiny optimization loss, peel_ref() expects the
value of current_ref not to change across a call to peel_entry(). But
in the presence of replace references that assumption could be
violated by a recursive call to do_one_ref:

do_for_each_entry()
do_one_ref()
builtin/describe.c:get_name()
peel_ref()
peel_entry()
peel_object ()
deref_tag_noverify()
parse_object()
lookup_replace_object()
do_lookup_replace_object()
prepare_replace_object()
do_for_each_ref()
do_for_each_entry()
do_for_each_entry_in_dir()
do_one_ref()

The inner call to do_one_ref() was unconditionally setting current_ref
to NULL when it was done, causing peel_ref() to perform an invalid
memory access.

So change do_one_ref() to save the old value of current_ref before
overwriting it, and restore the old value afterward rather than
setting it to NULL.

parse_object_buffer: correct freeing the buffer

If we exit early in the function parse_object_buffer, we did not
write to *eaten_p. Then the calling function parse_object, which looks
like the following with respect to the eaten variable, cannot rely on a
proper value set in eaten, hence the freeing of the buffer depends
on random values in memory.

struct object *parse_object(const unsigned char *sha1)
{
int eaten;
...
obj = parse_object_buffer(sha1, type, size, buffer, &eaten);
if (!eaten)
free(buffer);
}

This change makes sure, the buffer freeing condition is deterministic.

Documentation/git-log.txt: capitalize section names

This is the convention in most other files and even at the beginning of
git-log.txt

Documentation: move description of -s, --no-patch to diff-options.txt

Technically, "-s, --no-patch" is implemented in diff.c ("git diff
--no-patch" is essentially useless, but valid). From the user point of
view, this allows the documentation to show up in "git show --help",
which is one of the most useful use of the option.

While we're there, add a sentence explaining why the option can be
useful.
