Fix nasty approxidate bug

Stupid me.

If approxidate ends up with a month that is ahead of the current month, it

Which is correct, and means that "last december" does the right thing.

HOWEVER. It should only do so if the year is the same as the current year.

Without this fix, "5 days ago" ends up being in 2004, because it first
decrements five days, getting us to December 2005 (correct), but then it
also ends up decrementing the year once more to turn that December into

Linus Torvalds [Sat, 24 Dec 2005 21:50:45 +0000 (13:50 -0800)]
Add a "git-describe" command

It shows you the most recent tag that is reachable from a particular
commit is.

Maybe this is something that "git-name-rev" should be taught to do,
instead of having a separate command for it. Regardless, I find it useful.

What it does is to take any random commit, and "name" it by looking up the
most recent commit that is tagged and reachable from that commit. If the
match is exact, it will just print out that ref-name directly. Otherwise
it will print out the ref-name, followed by the 8-character "short SHA".

IOW, with something like Junios current tree, I get:

[torvalds@g5 git]$ git-describe parent
refs/tags/v1.0.4-g2414721b

ie the current head of my "parent" branch (ie Junio) is based on v1.0.4,
but since it has a few commits on top of that, it has added the git hash
of the thing to the end: "-g" + 8-char shorthand for the commit
2414721b194453f058079d897d13c4e377f92dc6.

Doing a "git-describe" on a tag-name will just show the full tag path:

[torvalds@g5 git]$ git-describe v1.0.4
refs/tags/v1.0.4

unless there are _other_ tags pointing to that commit, in which case it
will just choose one at random.

This is useful for two things:

 - automatic version naming in Makefiles, for example. We could use it in
   git itself: when doing "git --version", we could use this to give a
   much more useful description of exactly what version was installed.

 - for any random commit (say, you use "gitk <pathname>" or
   "git-whatchanged" to look at what has changed in some file), you can
   figure out what the last version of the repo was. Ie, say I find a bug
   in commit 39ca371c45b04cd50d0974030ae051906fc516b6, I just do:

[torvalds@g5 linux]$ git-describe 39ca371c45b04cd50d0974030ae051906fc516b6
refs/tags/v2.6.14-rc4-g39ca371c

   and I now know that it was _not_ in v2.6.14-rc4, but was presumably in
   v2.6.14-rc5.

The latter is useful when you want to see what "version timeframe" a
commit happened in.

ls-tree: chomp leading directories when run from a subdirectory

When run from a subdirectory, even though we filtered the output
based on where we were using pathspec, we wrote out the
repository relative paths, not subtree relative paths.  This
changes things so that it shows only the current subdirectory
relative paths.

For example, in Documentation subdirectory of git itself, this
used to be the case:

    $ git-ls-tree --name-only HEAD | grep how
    Documentation/git-show-branch.txt
    Documentation/git-show-index.txt
    Documentation/howto-index.sh
    Documentation/howto

But now it does this instead:

    $ git-ls-tree --name-only HEAD | grep how
    git-show-branch.txt
    git-show-index.txt
    howto-index.sh
    howto

There are two things to keep in mind.

1. This shows nothing.

   $ git-ls-tree --name-only HEAD ../ppc/

   This is to make things consistent with ls-files, which
   refuses relative path that goes uplevel.

2. These show things in full repository relative paths.  In this
   case, paths outside the current subdirectory are also shown.

   $ git-ls-tree --name-only --full-name HEAD | grep how
   Documentation/git-show-branch.txt
   Documentation/git-show-index.txt
   Documentation/howto-index.sh

   $ git-ls-tree --name-only --full-name HEAD ../ppc/
   ppc/sha1.c
   ppc/sha1.h
   ppc/sha1ppc.S

The flag --full-name gives the same behaviour as 1.0, so it
ought to be the default if we really care about the backward
compatibility, but in practice no Porcelain runs ls-tree from a
subdirectory yet, and without --full-name is more human
friendly, so hopefully the default being not --full-name would
be acceptable.

Make "git-send-pack" less verbose by default

It used to make sense to have git-send-pack talk about the things it sent
when (a) it was a new program and (b) nobody had a lot of tags and
branches.

These days, it's just distracting to see tons of

'refs/tags/xyz': up-to-date
...

when updating a remote repo.

So shut it up by default, and add a "--verbose" flag for those who really
want to see it.

Also, since this makes he case of everything being up-to-date just totally
silent, make it say "Everything up-to-date" if no refs needed updating.

Racy GIT

This fixes the longstanding "Racy GIT" problem, which was pretty
much there from the beginning of time, but was first
demonstrated by Pasky in this message on October 24, 2005:

    http://marc.theaimsgroup.com/?l=git&m=113014629716878

If you run the following sequence of commands:

echo frotz >infocom
        git update-index --add infocom
        echo xyzzy >infocom

so that the second update to file "infocom" does not change
st_mtime, what is recorded as the stat information for the cache
entry "infocom" exactly matches what is on the filesystem
(owner, group, inum, mtime, ctime, mode, length).  After this
sequence, we incorrectly think "infocom" file still has string
"frotz" in it, and get really confused.  E.g. git-diff-files
would say there is no change, git-update-index --refresh would
not even look at the filesystem to correct the situation.

Some ways of working around this issue were already suggested by
Linus in the same thread on the same day, including waiting
until the next second before returning from update-index if a
cache entry written out has the current timestamp, but that
means we can make at most one commit per second, and given that
the e-mail patch workflow used by Linus needs to process at
least 5 commits per second, it is not an acceptable solution.
Linus notes that git-apply is primarily used to update the index
while processing e-mailed patches, which is true, and
git-apply's up-to-date check is fooled by the same problem but
luckily in the other direction, so it is not really a big issue,
but still it is disturbing.

The function ce_match_stat() is called to bypass the comparison
against filesystem data when the stat data recorded in the cache
entry matches what stat() returns from the filesystem.  This
patch tackles the problem by changing it to actually go to the
filesystem data for cache entries that have the same mtime as
the index file itself.  This works as long as the index file and
working tree files are on the filesystems that share the same
monotonic clock.  Files on network mounted filesystems sometimes
get skewed timestamps compared to "date" output, but as long as
working tree files' timestamps are skewed the same way as the
index file's, this approach still works.  The only problematic
files are the ones that have the same timestamp as the index
file's, because two file updates that sandwitch the index file
update must happen within the same second to trigger the
problem.
