The statement:
assertThat(recvStream.available(), is(0));
results in a warning from Eclipse:
The expression of type int is boxed into Integer
because recvStream.available() returns int, but the hamcrest is()
method takes an Integer.
Replace it with the equivalent JUnit assertion.
Also remove the suppression of another similar warning and fix that

The parsing code for protocol v2 fetch doesn't have any dependency on
the rest of UploadPack.
Move it to its own class. This makes testing easier (no need to
instantiate the full UploadPack), simplifies the code in UploadPack and
increases modularity.
At the moment, the parser needs to know about the reference database to
validate incoming references. This dependency could be easily removed
moving the validation later in the flow, after the parsing, where other
validations are already happening. Postponing that to keep this patch
about moving unmodified code around.

At the moment there are two copies of the client shallow commit list:
one in the request and another in the clientShallowCommits member of
the class.
The verifyShallowCommit function was removing missing object ids
from the member but not the request list, and code afterwards was
using the request's version.
In practice, this didn't cause trouble because these shallow commits
are used as endpoint for a walk, and missing ids are just never reached.

If packed refs are used, duplicate updates result in an exception
because JGit tries to lock the same lock file twice. With non-atomic
ref updates, this used to work, since the same ref would simply be
locked and updated twice in succession.
Let's be more lenient in this case and remove duplicates before
trying to do the ref updates. Silently skip duplicate updates
for the same ref, if they both would update the ref to the same
object ID. (If they don't, behavior is undefined anyway, and we
still throw an exception.)
Add a test that results in a duplicate ref update for a tag.

In Git protocol v2, UploadPack and ReceivePack have the same
capabilities and can process any protocol v2 request. For example, a
client can sent a "fetch" command to the "/git-receive-pack" endpoint.
This makes it difficult for existing hook interfaces. For example,
PreUploadHook takes UploadPack, but a "fetch" command may be received by
ReceivePack.
To resolve this skew, this change introduce a different hook interface
for the protocol v2. The hook takes a request that is independent to the
handlers (UploadPack, ReceivePack). Also this makes it clear what
parameters the hook is counting on, instead of keep track of the hook
using getters from UploadPack / ReceivePack.

UploadPack already allows the client to send wanted OIDs as "want"
lines. Extend UploadPack to also allow the client to send wanted ref
names as "want-ref" lines when the fetch is done using protocol v2.
The corresponding Git commit is 516e2b76bd ("upload-pack: implement
ref-in-want", 2018-06-28).
To support a two-stage rollout, two configuration variables are
provided: uploadpack.allowrefinwant (default "false") allows clients to
specify "want-ref" in their requests, and uploadpack.advertiserefinwant
(default "true") makes UploadPack advertise this capability. If
uploadpack.allowrefinwant is true but uploadpack.advertiserefinwant is
false, UploadPack will not advertise that it supports "want-ref", but it
will support it.

Two submodules at the same path on different branches need not represent
the same repository, and two submodules at different paths can represent
the same one.
The C Git implementation uses the submodule name to internally manage
the submodule repositories under .git/modules. When a submodule
represents different repositories in different branches, it makes a
conflict inside .git/modules.
The current RepoCommand implementation uses submodule paths as the
submodule names. When the manifest file mounts different repositories to
the same path in different branches, this makes a situation described
above. To solve this issue, we can use the project name instead of
the path as the submodule name.
On the other hand, since repo v1.12.8~3^2 (repo: Support multiple
branches for the same project., 2013-10-11), a manifest file can mount
the same project to different paths. If we naively use the project
name as the submodule name, it makes a conflict in .git/modules, too.
This patch uses the project name as the submodule name basically, but
when the same project is mounted to different paths, it uses the project
name and path as the submodule name.

In a new RevWalk, if the first object parsed is one of the
shallow commits, the following happens:
1) RevCommit.parseCanonical() is called on a new "r1" RevCommit.
2) RevCommit.parseCanonical() immediately calls
RevWalk.initializeShallowCommits().
3) RevWalk.initializeShallowCommits() calls lookupCommit(id),
creating and adding a new "r2" version of this same object and
marking its parents empty.
4) RevCommit.parseCanonical() initializes the "r1" RevCommit's
fields, including the parents.
5) RevCommit.parseCanonical()'s caller uses the "r1" commit that
has parents, losing the fact that it is a shallow commit.
This change passes the current RevCommit as an argument to
RevWalk.initializeShallowCommits() so that method can set its
parents empty rather than creating the duplicate "r2" commit.

JGit's implementation of the fetch command of protocol v2, unlike its
implementation of ls-refs, currently tolerates unknown arguments.
Tighten fetch to not allow unrecognized arguments and add tests to
verify this behavior for both ls-refs and fetch.

Provide a factory for comparators that use the default heuristics except
with a different ordering of PackSources.
Change-Id: I0809b64deb3d0486040076946fdbdad650d69240
There are several ways of comparing DfsPackDescriptions for different
purposes, such as object lookup search order and reftable ordering. Some
of these are later compounded into comparators on other objects, so they
appear in the code as Comparator<DfsReftable>, for example.
Put all the DfsPackDescription comparators in static methods on
DfsPackDescription itself. Stop implementing Comparable, to avoid giving
the impression that there is always one true and correct way of sorting
packs.

Rather than requiring callers to do their own computations based on the
package-private "category" number, provide an actual
Comparator<PackSource> instance, and explicitly discourage usage of
default Enum comparison.
Construct the default comparator using a builder pattern based on
defining equivalence classes. This gives us the same behavior as the old
category field in PackSource, with an abstraction that does not leak the
implementation detail of comparing rank numbers.

Callers of getAllRefs that only iterate over the `values()` of the
returned map can be trivially fixed to call getRefDatabase().getRefs()
instead.
Only fix those where the calling method is already declared to throw
IOException, to avoid potential API changes.

Callers should use getRefDatabase().peel(ref) instead since it
doesn't swallow the IOException.
Adapt all trivial callers to user the alternative.
DescribeCommand still uses the deprecated method and is not adapted in
this change since it will require more refactoring to add handling of
the IOException.

Make FileTreeIterator not enter ignored directories by default. We
only need to enter ignored directories if we do some operation against
git, and there is at least one tracked file underneath an ignored
directory.
Walking ignored directories should be avoided as much as possible as
it is a potential performance bottleneck. Some projects have a lot of
files or very deep hierarchies in ignored directories; walking those
may be costly (especially so on Windows). See for instance also bug
500106.
Provide a FileTreeIterator.setWalkIgnoredDirectories() operation to
force the iterator to iterate also through otherwise ignored
directories. Useful for tests (IgnoreNodeTest, CGitIgnoreTest), or
to implement things like "git ls-files --ignored".
Add tests in DirCacheCheckoutTest, and amend IndexDiffTest to test a
little bit more.

protocol v2. This patch teaches "have" and "done".
The protocol specification (Documentation/technical/protocol-v2.txt in
the Git project) states:
want <oid>
Indicates to the server an object which the client wants to
retrieve. Wants can be anything and are not limited to
advertised objects.
It is unspecified whether the server should respect the
uploadpack.allowtipsha1inwant option etc. when serving packfiles. This
patch is conservative in that the server respects them.

Most pkt-lines (data-pkts) have the form
pkt-len pkt-payload
where pkt-len is a string of 4 hexadecimal digits representing the
size in bytes of the pkt-line. Since this size includes the size of
the pkt-len, no data-pkt has a length less than 4.
A pkt-line with a length field less than 4 can thus be used for
other purposes. In Git protocol v1, the only such pkt-line was
flush-pkt = "0000"
which was used to mark the end of a stream. Protocol v2 (see
Documentation/technical/protocol-v2.txt in git.git) introduces a
second special pkt-line type:
delim-pkt = "0001"
used to mark the end of a section within a stream, for example to
separate capabilities from the content of a command.

The existing RefDatabase#getRefs abstract method (to be implemented by
ref database backends) has the following issues:
- It returns a map with a key (the name of the ref with the prefix
removed) which is potentially superfluous (it can be derived by the
caller if need be) and confusing (in that the prefix is removed).
- The prefix is required to end with a '/', but some backends (e.g.
reftable) have fast search by prefix regardless of what the last
character of the prefix is.
Add a new method #getRefsByPrefix that does not have these issues. This
is non-abstract with a default implementation that uses #getRefs (for
backwards compatibility), but ref database backends can reimplement it.
This also prepares for supporting "ref-prefix" in the "ls-refs" command
in the fetch-pack/upload-pack protocol v2, which does not require that
the prefix end with a '/'.

Various places on the client side of the push were creating unordered
maps and sets of ref names, resulting in ReceivePack processing commands
in an order other than what the client provided. This is normally not
problematic for clients, who don't typically care about the order in
which ref updates are applied to the storage layer.
However, it does make it difficult to write deterministic tests of
ReceivePack or hooks whose output depends on the order in which commands
are processed, for example if informational per-ref messages are written
to a sideband.[1]
Add a test that ensures the ordering of commands both internally in
ReceivePack and in the output PushResult.
