Unless the user explicitly asked hardlinking with the '-l'
option, we should not say "oops we cannot hardlink as you asked
so we are copying".

This changes the behaviour of cloning from a repository on the
local machine, by defaulting to "-l" (use hardlinks to share
files under .git/objects) and making "-l" a no-op. A new
option, --no-hardlinks, is also added to cause file-level copy
of files under .git/objects while still avoiding the normal
"pack to pipe, then receive and index pack" network transfer
overhead. The old behaviour of local cloning without -l nor -s
is availble by specifying the source repository with the newly
introduced file:///path/to/repo.git/ syntax (i.e. "same as
network" cloning).
* With --no-hardlinks (i.e. have all .git/objects/ copied via
cpio) would not catch the source repository corruption, and
also risks corrupted recipient repository if an
alpha-particle hits memory cell while indexing and resolving
deltas. As long as the recipient is created uncorrupted, you
have a good back-up.
* same-as-network is expensive, but it would catch the breakage
of the source repository. It still risks corrupted recipient
repository due to hardware failure. As long as the recipient
is created uncorrupted, you have a good back-up.
* The new default on the same filesystem, as long as the source
repository is healthy, it is very likely that the recipient
would be, too. Also it is very cheap. You do not get any
back-up benefit, though.
None of the method is resilient against the source repository
corruption, so let's discount that from the comparison. Then
the difference with and without --no-hardlinks matters primarily
if you value the back-up benefit or not. If you want to use the
cloned repository as a back-up, then it is cheaper to do a clone
with --no-hardlinks and two git-fsck (source before clone,
recipient after clone) than same-as-network clone, especially as
you are likely to do a git-fsck on the recipient if you are so
paranoid anyway.
Which leads me to believe that being able to use file:/// is
probably a good idea, if only for testability, but probably of
little practical value. We default to hardlinked clone for
everyday use, and paranoids can use --no-hardlinks as a way to
make a back-up.

If you have /home/me/git symlink pointing at /pub/git/mine,
trying to clone from /pub/git/his/ using relative path would not
work as expected:
$ cd /home/me
$ cd git
$ ls ../
his mine
$ git clone -l -s -n ../his/stuff.git
This is because "cd ../his/stuff.git" done inside git-clone to
check if the repository is local is confused by $PWD, which is
set to /home/me, and tries to go to /home/his/stuff.git which is
different from /pub/git/his/stuff.git.
We could probably say "set -P" (or "cd -P") instead, if we know
the shell is POSIX, but the way the patch is coded is probably
more portable.

The intent of the commit 'fetch & clone: do not output progress when
not on a tty' was to make fetching and cloning less chatty when
output was not redirected (such as in a cron job).
However, there was a serious thinko in that commit. It assumed that
the client _and_ the server got this update at the same time. But
this is obviously not the case, and therefore upload-pack died on
seeing the option "--no-progress".
This patch fixes that issue by making it a protocol option. So, until
your server is updated, you still see the progress, but once the
server has this patch, it will be quiet.
A minor issue was also fixed: when cloning, the checkout did not
heed no_progress.

Earlier we only used loose refs to anchor already existing

long time ago from the reference repository, this made the
want/have exchange by fetch-pack to do unnecessary work.
Signed-off-by: Junio C Hamano <junkio@cox.net>
When using --reference to borrow objects from a neighbouring
repository while cloning, we copy the entire set of refs under
temporary "refs/reference-tmp/refs" space and set up the object
alternates. However, a textual symref copied this way would not
point at the right place, and causes later steps to emit error
messages (which is harmless but still alarming). This is most
visible when using a clone created with the separate-remote
layout as a reference, because such a repository would have
refs/remotes/origin/HEAD with 'ref: refs/remotes/origin/master'
as its contents.
Although we do not create symbolic-link based refs anymore, they
have the same problem because they are always supposed to be
relative to refs/ hierarchy (we dereference by hand, so it only
is good for HEAD and nothing else).
In either case, the solution is simply to remove them after
copying under refs/reference-tmp; if a symref points at a true
ref, that true ref itself is enough to ensure that objects
reachable from it do not needlessly get fetched.

Recent commit ae1dffcb28 by Junio
changed the way --upload-pack was passed around between clone,
fetch and ls-remote and modified the handling of the command
line parameter parsing.
Unfortunately FreeBSD 6.1 insists that the expression
expr --upload-pack=git-upload-pack : '-[^=]*=\(.*\)'
is illegal, as the --upload-pack option is not supported by their
implementation of expr.
Elsewhere in Git we use z as a leading prefix of both arguments,
ensuring the -- isn't seen by expr.

This changes the default remote.origin.fetch configuration
created by git-clone so that it allows non-fast-forward updates.
When using the separate-remote layout with reflog enabled, it
does not make much sense to refuse to update the remote tracking
branch just because some of them do not fast-forward. git-fetch
issues warnings on non-fast-forwardness, and the user can peek
at what the previous state was using the reflog.

Finally.
The separate-remote layout is so much more organized than
traditional and easier to work with especially when you need to
deal with remote repositories with multiple branches and/or you
need to deal with more than one remote repositories, and using
traditional layout for new repositories simply does not make
much sense.
Internally we still have code for 1:1 mappings to create a bare
clone; that is a good thing and will not go away.

Now we lost the "first refspec is the one that is merged by default"

This stops enumerating the set of branches found on the remote
side when a clone was made in the configuration file. Instead,
a single entry that maps each remote branch to the local
tracking branch for the remote under the same name is created.
Doing it this way not only shortens the configuration file, but
automatically adjusts to a new branch added on the remote side
after the clone is made.
Unfortunately this cannot be done for the traditional layout,
where we always need to special case the 'master' to 'origin'
mapping within the local branch namespace. But that is Ok; it
will be going away before v1.5.0.
We could also lose the "primary branch" mapping at the
beginning, but that has to wait until we implement the "forbid
'git pull' when we do not have branch.$current.merge for the
current branch" policy we earlier discussed. That should also
be in v1.5.0

Without any specification in the .git/config file, git-pull will execute
"git-pull origin"; which in turn defaults to pull from the first "pull"
definition for the remote, "origin".
This is a difficult set of defaults to track for a new user, and it's
difficult to see what tells git to do this (especially when it is
actually hard-coded behaviour). To ameliorate this slightly, this patch
explicitly specifies the default behaviour during a clone using the
"branch" section of the config.
For example, a clone of a typical repository would create a .git/config
containing:
[remote "origin"]
url = proto://host/repo.git
fetch = refs/heads/master:refs/remotes/origin/master
[branch "master"]
remote = origin
merge = refs/heads/master
The [branch "master"] section is such that there is no change to the
functionality of git-pull, but that functionality is now explicitly
documented.

Most notably, the original code first copied refs/remotes/ that

By specifying a depth, you can now clone a repository such that
all fetched ancestor-chains' length is at most "depth". For example,
if the upstream repository has only 2 branches ("A" and "B"), which

B, B~1, B~2, and B~3. The ends are automatically made shallow
