We use 'xargs cp' to emulate 'cpio -pumd'.
cpio is fed from the output of 'find --depth' without filtering out
directories. We don't need to copy directories except the empty ones, so
we need to filter out non-empty directories. Then we can use 'cp -r' and
it will not actually recurse anything.

If the PATH lists the Windows system directories before the MSYS
directories, Windows's own incompatible sort and find commands would be
picked up. We implement these commands as functions and call the real
tools by absolute path.
Also add a dummy implementation of sync to avoid an error in git-repack.

If the curl program is not available (or not executable), and git clone is
started to clone a repository through http, this is the output
Initialized empty Git repository in /tmp/puppet/.git/
/usr/bin/git-clone: line 37: curl: command not found
Cannot get remote repository information.
Perhaps git-update-server-info needs to be run there?
This patch improves the error message by checking the return code when
running curl to exit immediately if it's 126 or 127; the error output now
is
Initialized empty Git repository in /tmp/puppet/.git/
/usr/bin/git-clone: line 37: curl: command not found

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.

The default of pwd of MSYS's bash and /bin/pwd are to use /c/rest/of/path
notation instead of c:/rest/of/path. But the former is not supported
by programs that use the standard C runtime (instead of MinGW's own
runtime). Hence, we must make sure that only drive letter notations
are generated by using pwd's -W option.
c2f599e09f introduced a buglet while
cloning from a remote URL; we forgot to squelch the unnecessary
error message when we try to cd to the given "remote" name,
in order to see if it is a local directory.

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
objects. When cloning from a repository that forked relatively
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.
