When creating a shallow clone of a repository with submodules, the depth
argument does not influence the submodules, i.e. the submodules are done
as non-shallow clones. It is unclear what the best default is for the
depth of submodules of a shallow clone, so we need to have the possibility
to do all kinds of combinations:
* shallow super project with shallow submodules
e.g. build bots starting always from scratch. They want to transmit
the least amount of network data as well as using the least amount
of space on their hard drive.
* shallow super project with unshallow submodules
e.g. The superproject is just there to track a collection of repositories
and it is not important to have the relationship between the repositories
intact. However the history of the individual submodules matter.
* unshallow super project with shallow submodules
e.g. The superproject is the actual project and the submodule is a
library which is rarely touched.
The new switch to select submodules to be shallow or unshallow supports
all of these three cases.
It is easy to transition from the first to the second case by just
unshallowing the submodules (`git submodule foreach git fetch
--unshallow`), but it is not possible to transition from the second to the
first case (as we would have already transmitted the non shallow over
the network). That is why we want to make the first case the default in
case of a shallow super project. This leads to the inconvenience in the
second case with the shallow super project and unshallow submodules,
as you need to pass `--no-shallow-submodules`.

A major part of "git submodule update" has been ported to C to take
advantage of the recently added framework to run download tasks in
parallel.
* sb/submodule-parallel-update:
clone: allow an explicit argument for parallel submodule clones
submodule update: expose parallelism to the user
submodule helper: remove double 'fatal: ' prefix
git submodule update: have a dedicated helper for cloning
run_processes_parallel: rename parameters for the callbacks
run_processes_parallel: treat output of children as byte array
submodule update: direct error message to stderr
fetching submodules: respect `submodule.fetchJobs` config option
submodule-config: drop check against NULL
submodule-config: keep update strategy around
Just pass it along to "git submodule update", which may pick reasonable
defaults if you don't specify an explicit number.

It turns out "git clone" over rsync transport has been broken when
the source repository has packed references for a long time, and
nobody noticed nor complained about it.
* jk/drop-rsync-transport:
transport: drop support for git-over-rsync
The git-over-rsync protocol is inefficient and broken, and
has been for a long time. It transfers way more objects than
it needs (grabbing all of the remote's "objects/",
regardless of which objects we need). It does its own ad-hoc
parsing of loose and packed refs from the remote, but
doesn't properly override packed refs with loose ones,
leading to garbage results (e.g., expecting the other side
to have an object pointed to by a stale packed-refs entry,
or complaining that the other side has two copies of the
refs[1]).
This latter breakage means that nobody could have
successfully pulled from a moderately active repository
since cd547b4 (fetch/push: readd rsync support, 2007-10-01).
We never made an official deprecation notice in the release
notes for git's rsync protocol, but the tutorial has marked
it as such since 914328a (Update tutorial., 2005-08-30).
And on the mailing list as far back as Oct 2005, we can find
Junio mentioning it as having "been deprecated for quite
some time."[2,3,4]. So it was old news then; cogito had
deprecated the transport in July of 2005[5] (though it did
come back briefly when Linus broke git-http-pull!).
Of course some people professed their love of rsync through
2006, but Linus clarified in his usual gentle manner[6]:
> Thanks! This is why I still use rsync, even though
> everybody and their mother tells me "Linus says rsync is
> deprecated."
No. You're using rsync because you're actively doing
something _wrong_.
The deprecation sentiment was reinforced in 2008, with a
mention that cloning via rsync is broken (with no fix)[7].
Even the commit porting rsync over to C from shell (cd547b4)
lists it as deprecated! So between the 10 years of informal
warnings, and the fact that it has been severely broken
since 2007, it's probably safe to simply remove it without
further deprecation warnings.

The "--reference" option is not the only way to provide a repository
to borrow objects from. A repository that borrows from another

While use of the --reference option to borrow objects from an
existing local repository of the same project is an effective way to
reduce traffic when cloning a project over the network, it makes the
resulting "borrowing" repository dependent on the "borrowed"
repository. After running
git clone --reference=P $URL Q
the resulting repository Q will be broken if the borrowed repository
P disappears.
The way to allow the borrowed repository to be removed is to repack
the borrowing repository (i.e. run "git repack -a -d" in Q); while
power users may know it very well, it is not easily discoverable.
Teach a new "--dissociate" option to "git clone" to run this
repacking for the user.

"It fails reliably without corrupting the receiving repository when

end was hardened recently, but the fact that sometimes the push does

The document says one cannot push from a shallow clone. But that is
not true (maybe it was at some point in the past). The client does not
stop such a push nor does it give any indication to the receiver that
this is a shallow push. If the receiver accepts it, it's in.
Since 52fed6e (receive-pack: check connectivity before concluding "git
push" - 2011-09-02), receive-pack is prepared to deal with broken
push, a shallow push can't cause any corruption. Update the document
to reflect that.

A repository created with "git clone --single" had its fetch
refspecs set up just like a clone without "--single", leading the
subsequent "git fetch" to slurp all the other branches, defeating
the whole point of specifying "only this branch".
* rt/maint-clone-single:
clone --single: limit the fetch refspec to fetched branch
After running "git clone --single", the resulting repository has the
usual default "+refs/heads/*:refs/remotes/origin/*" wildcard fetch
refspec installed, which means that a subsequent "git fetch" will
end up grabbing all the other branches.
Update the fetch refspec to cover only the singly cloned ref instead
to correct this.
That means:
If "--single" is used without "--branch" or "--mirror", the
fetch refspec covers the branch on which remote's HEAD points to.
If "--single" is used with "--branch", it'll cover only the branch
specified in the "--branch" option.
If "--single" is combined with "--mirror", then it'll cover all
refs of the cloned repository.
If "--single" is used with "--branch" that specifies a tag, then
it'll cover only the ref for this tag.

Clone does all of init, "remote add", fetch, and checkout
without giving the user a chance to intervene and set any
configuration. This patch allows you to set config options
in the newly created repository after the clone, but before
we do any other operations.
In many cases, this is a minor convenience over something
like:
git clone git://...
git config core.whatever true
But in some cases, it can bring extra efficiency by changing
how the fetch or checkout work. For example, setting
line-ending config before the checkout avoids having to
re-checkout all of the contents with the correct line
endings.
It also provides a mechanism for passing information to remote
helpers during a clone; the helpers may read the git config
to influence how they operate.

The point of these sections is generally to:
1. Give credit where it is due.
2. Give the reader an idea of where to ask questions or
file bug reports.
But they don't do a good job of either case. For (1), they
are out of date and incomplete. A much more accurate answer
can be gotten through shortlog or blame. For (2), the
correct contact point is generally git@vger, and even if you
wanted to cc the contact point, the out-of-date and
incomplete fields mean you're likely sending to somebody
useless.
So let's drop the fields entirely from all manpages except
git(1) itself. We already point people to the mailing list
for bug reports there, and we can update the Authors section
to give credit to the major contributors and point to
shortlog and blame for more information.
Each page has a "This is part of git" footer, so people can
follow that to the main git manpage.

It is misleading to say that we pull refs from $GIT_DIR/refs/*, because we
may also consult the packed refs mechanism. These days we tend to treat
the "refs hierarchy" as more of an abstract namespace that happens to be
represented as $GIT_DIR/refs. At best, this is a minor inaccuracy, but at
worst it can confuse users who then look in $GIT_DIR/refs and find that it
is missing some of the refs they expected to see.
This patch drops most uses of "$GIT_DIR/refs/*", changing them into just
"refs/*", under the assumption that users can handle the concept of an
abstract refs namespace. There are a few things to note:
- most cases just dropped the $GIT_DIR/ portion. But for cases where
that left _just_ the word "refs", I changed it to "refs/" to help
indicate that it was a hierarchy. I didn't do the same for longer
paths (e.g., "refs/heads" remained, instead of becoming
"refs/heads/").
- in some cases, no change was made, as the text was explicitly about
unpacked refs (e.g., the discussion in git-pack-refs).
- In some cases it made sense instead to note the existence of packed
refs (e.g., in check-ref-format and rev-parse).
