git-fast-import requires use of inttypes.h, but the master branch has
added it to git-compat-util differently than git-fast-import originally
had used it.  This merge back of master to the fast-import topic is to
get (and use) inttypes.h the way master is using it.

This is a partially evil merge to remove the call to setup_ident(),
as the master branch now contains a change which makes this implicit
and therefore removed the function declaration. (commit 01754769).

We used to use lock_any_ref_for_update() because the command
needs to also update HEAD (which is not under refs/, so
lock_ref_sha1() cannot be used).  The function however did not
check for refs with illegal characters in them.

Use check_ref_format() to catch malformed refs.  For this check,
we specifically do not want to say having less than two levels
in the name is illegal to allow HEAD (and perhaps other special
refs in the future).

I know it's only an example, but having this might save someone else the
trouble of writing an enhanced version for themselves.

It basically does the same job as the old update hook, but with these
differences:
 * The recipients list is read from the repository config file from
   hooks.mailinglist
 * Updating unannotated tags can be allowed by setting
   hooks.allowunannotated
 * Announcement emails (via annotated tag creation) can be sent to a
   different mailing list by setting hooks.announcelist
 * Output email is more verbose and generates specific content depending
   on whether the ref is a tag, an annotated tag, a branch, or a
   tracking branch
 * The email is easier to filter; the subject line is prefixed with
   [SCM] and a project description pulled from the "description" file
 * It catches (and displays differently) branch updates that are
   performed with a --force

Obviously, it's nothing that clever - it's the update hook I use on my
repositories but I've tried to keep it general, and tried to make the
output always relevant to the type of update.

I got bitten because in the UK (where one would expect 1970-01-01 00:00
to be UTC 0) some politicians decided to mess around with daylight
savings time from 1968 to 1971; it was permanently BST (+0100).  That
means that on my computer the following is true:

	$ date --date="1970-01-01 00:00" +"%F %T %z (%Z)"
	1970-01-01 00:00:00 +0100 (BST)

This of course means that the --date argument to date is specified in
local time, not UTC.  So when the hooks--update script does this:

	date=$(date --date="1970-01-01 00:00:00 $ts seconds")

It's actually saying (in my timezone) "1970-01-01 01:00:00 UTC" + $ts.
Clearly this is wrong.  The UNIX epoch started at midnight UTC not 1am
UTC.

This leads to the tagged time in hooks--update being shown as one hour
earlier than the true tagged time (in my timezone).  The problem would
be worse for other timezones.  For a +1300 timezone on 1970-01-01, the
tagged time would be 13 hours earlier.  Oops.

The solution is to force the reference time to UTC, which is what this
patch does.  In my timezone:

	$ date --date="1970-01-01 00:00 +0000" +"%F %T %z (%Z)"
	1970-01-01 01:00:00 +0100 (BST)

Much better.

This allows pushing over the git:// protocol, and while it's not

My prior change to git-describe attempts to print the distance
between the input commit and the best matching tag, but this distance
was usually only an estimate as we always aborted revision walking
as soon as we overflowed the configured limit on the number of
possible tags (as set by --candidates).

Displaying an estimated distance is not very useful and can just be
downright confusing.  Most users (heck, most Git developers) don't
immediately understand why this distance differs from the output
of common tools such as `git rev-list | wc -l`.  Even worse, the
estimated distance could change in the future (including decreasing
despite no rebase occuring) if we find more possible tags earlier
on during traversal.  (This could happen if more tags are merged
into the branch between queries.)  These factors basically make an
estimated distance useless.

Fortunately we are usually most of the way through an accurate
distance computation by the time we abort (due to reaching the
current --candidates limit).  This means we can simply finish
counting out the revisions still in our commit queue to present
the accurate distance at the end.  The number of commits remaining
in the commit queue is probably less than the number of commits
already traversed, so finishing out the count is not likely to take
very long.  This final distance will then always match the output of
`git rev-list | wc -l`.

We can easily reduce the total number of commits that need to be
walked at the end by stopping as soon as all of the commits in the
commit queue are flagged as being merged into the already selected
best possible tag.  If that's true then there are no remaining
unseen commits which can contribute to our best possible tag's
depth counter, so further traversal is useless.

Basic testing on my Mac OS X system shows there is no noticable
performance difference between this accurate distance counting
version of git-describe and the prior version of git-describe,
at least when run on git.git.

If you get two different describes at different

rather common in practice, so its incredibly useful.

Otherwise a pathname that has funny characters such as LF would
screw up the parsing programs of the output.

Strictly speaking, this is not backward compatible, but the

This adds --incremental option to help GUI porcelains to show

origin information in the same format as the porcelain format.
The first line has commit object name, the line number of the
first line in the group in the original file, the line number of
that file in the final image, and number of lines in the group.
Then subsequent lines show the metainformation for the commit
when the commit is shown for the first time, except the filename
information is always shown (we cannot even make it conditional
to -C option as blame always follows the renaming of the file

Back when only handful commands that created commit and tag were
the only users of committer identity information, it made sense
to explicitly call setup_ident() to pre-fill the default value
from the gecos information.  But it is much simpler for programs

since many more programs want to use the information when updating

I did this:

  $ git tag -s test-sign
  gpg: skipped "Andy Parkins <andyparkins@gmail.com>": secret key not available
  gpg: signing failed: secret key not available
  failed to sign the tag with GPG.

The problem is that I have used the comment field in my key's UID
definition.

  $ gpg --list-keys andy
  pub   1024D/4F712F6D 2003-08-14
  uid                  Andy Parkins (Google) <andyparkins@gmail.com>

So when git-tag looks for "Andy Parkins <andyparkins@gmail.com>";
obviously it's not going to be found.

There shouldn't be a requirement that I use the same form of my name in
my git repository and my gpg key - I might want to be formal (Andrew) in
my gpg key and informal (Andy) in the repository.  Further I might have
multiple keys in my keyring, and might want to use one that doesn't
match up with the address I use in commit messages.

This patch adds a configuration entry "user.signingkey" which, if
present, will be passed to the "-u" switch for gpg, allowing the tag
signing key to be overridden.  If the entry is not present, the fallback
is the original method, which means existing behaviour will continue
untouched.

When on a non-tag commit, git-describe normally outputs descriptions of
the form
  v1.0.0-g1234567890
Some scripts (for example the update hook script) might just want to
know the name of the nearest tag, so they then have to do
 x=$(git-describe HEAD | sed 's/-g*//')
This is costly, but more importantly is fragile as it is relying on the
output format of git-describe, which we would then have to maintain
forever.

This patch adds support for setting the --abbrev option to zero.  In
that case git-describe does as it always has, but outputs only the
nearest found tag instead of a completely unique name.  This means that
scripts would not have to parse the output format and won't need
changing if the git-describe suffix is ever changed.
