send-pack: reword non-fast-forward error message.
Wnen refusing to push a head, we said cryptic "remote 'branch'
object X does not exist on local" or "remote ref 'branch' is not
a strict subset of local ref 'branch'". That was gittish.
Since the most likely reason this happens is because the pushed
head was not up-to-date, clarify the error message to say that
straight, and suggest pulling first.

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.

could be easily accomodated to that too. Matter of taste and preference, I

Remove misguided branch disambiguation.
This removes the misguided attempt to refuse processing a branch
name xyzzy and insist it to be given as either heads/xyzzy or
tags/xyzzy when a tag xyzzy exists. There was no reason to do
so --- the search order was predictable and well defined, so if
the user says xyzzy we should have taken the tag xyzzy in such a
case without complaining.
This incidentally fixes another subtle bug related to this. If
such a duplicate branch/tag name happened to be a unique valid
prefix of an existing commit object name (say, "beef"), we did
not take the tag "beef" but after complaining used the commit
object whose name started with beef.
Another problem this fixes while introducing some confusion is
that there is no longer a reason to forbid a branch name HEAD
anymore. In other words, now "git pull . ref1:HEAD" would work
as expected, once we revert "We do not like HEAD branch" patch.
It creates "HEAD" branch under ${GIT_DIR-.git}/refs/heads (or
fast-forwards if already exists) using the tip of ref1 branch
from the current repository, and merges it into the current
branch.

This makes git-check-ref-format fail for "HEAD". Since the check is only

get_sha1_basic(): corner case ambiguity fix
When .git/refs/heads/frotz and .git/refs/tags/frotz existed, and
the object name stored in .git/refs/heads/frotz were corrupt, we
ended up picking tags/frotz without complaining. Worse yet, if
the corrupt .git/refs/heads/frotz was more than 40 bytes and

initial part of the returned result.
This commit adds a couple of tests to demonstrate these cases,

clone-pack: make it usable for partial branch cloning.
clone-pack had some logic to accept subset of remote refs from
the command line and clone from there. However, it was never
used in practice and its problems were not found out so far.
This commit changes the command to output the object names of
refs to the standard output instead of making a clone of the
remote repository when explicit <head> parameters are given; the
output format is the same as fetch-pack.
The traditional behaviour of cloning the whole repository by
giving no explicit <head> parameters stays the same.

Usage message clean-up, take #2
There were some problems with the usage message clean-up patch
series. I hadn't realised that subdirectory aware scripts can't source
git-sh-setup. I propose that we change this and let the scripts which
are subdirectory aware set a variable, SUBDIRECTORY_OK, before they
source git-sh-setup.
The scripts will also set USAGE and possibly LONG_USAGE before they
source git-sh-setup. If LONG_USAGE isn't set it defaults to USAGE.
If we go this way it's easy to catch --help in git-sh-setup, print the
(long) usage message to stdout and exit cleanly. git-sh-setup can
define a 'usage' shell function which can be called by the scripts to
print the short usage string to stderr and exit non-cleanly. It will
also be easy to change $0 to basename $0 or something else, if would
like to do that sometime in the future.
What follows is a patch to convert a couple of the commands to this
style. If it's ok with everyone to do it this way I will convert the
rest of the scripts too.

t/t6022: a new test for renaming merge.
This adds a couple of tests to cover the following renaming
merge cases:
- one side renames and the other side does not, with and without
content conflicts.
- both side rename to the same path, with and without content
conflicts.
The test setup also prepares a case in which both side rename to
different destination, but currently the code collapses these
destination paths and removes the original path, which may be
wrong. The outcome of this case is not checked by the tests in
this round.

merge-recursive: cleanup setIndexStages
Fredrik points out there is a useful wrapper runProgram() used
everywhere that we can use to feed input into subprocess. Use
it to catch errors from the subprocess; it is a good cleanup as
well.

merge-recursive: leave unmerged entries in the index.
This does two things.
- When one branch renamed and the other branch did not, the
resulting half-merged file in the working tree used to swap
branches around and showed as if renaming side was "ours".
This was confusing and inconsistent (even though the conflict
markers were marked with branch names, it was not a good
enough excuse). This changes the order of arguments to
mergeFile in such a case to make sure we always see "our"
change between <<< and ===, and "their" change between ===
and >>>.
- When both branches renamed to the same path, and when one
branch renamed and the other branch did not, we attempt
mergeFile. When this automerge conflicted, we used to
collapse the index. Now we use update-index --index-info
to inject higher stage entries to leave the index in unmerged
state for these two cases.
What this still does _not_ do is to inject unmerged state into
the index when the structural changes conflict. I have not
thought things through what to do in each case yet, but the
cases this commit cover are the most common ones, so this would
be a good start.
