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
in the same way.

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.

This test was never being run. Since it was introduced it was
named "notest.." which meant it didn't run with JUnit3, and
since it is not annotated @Test it also doesn't run with JUnit4.
When compiling with Bazel 0.6.0, error-prone raises an error
that the public method is not annotated with @Ignore or @Test.
Given that the test has never been run anyway, we can just

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.

Don't try to delete folders if the merger chooses THEIRS, but all of
BASE, OURS, and THEIRS contain the folder.
Add a test for rebase with auto-stash and subdirectories that

such directories in getModifiedFiles() was the root cause of bug
536880.
Note even with this fix, bug 536880 will not be fixed in all cases
yet. There may still be cases where the set of modified files ends
up containing directories. This will be dealt with in EGit where
this set is used. (See https://git.eclipse.org/r/#/c/126242/ .)

Make the method names more consistent and their semantics simpler:
hasRef and seekRef to look up a single exact reference by name and
hasRefsByPrefix and seekRefsByPrefix to look up multiple references by
name prefix.
In particular, splitting hasRef into two separate methods for its
different uses makes DfsReftableDatabase.isNameConflicting easier to
follow.

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.
