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.

Since I3870cadb4, GC task was always delegated to an executor even when
background option was set to false. This was an issue because if more
than one GC object was instantiated and executed in parallel, only one GC
was actually running because of the single thread executor.

When fetching with protocol v2, git expects the shallow-info section to
appear before wanted-refs if both appear in the response. Teach
UploadPack to do this.

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.

It's easier to read a list of cases
case A:
case B:
case C:
... do something ...;
break;
without intervening "// fall through" lines separating the cases.
This also makes it clearer that JGit uses "$FALL-THROUGH$", not "fall
through", to suppress fallthrough warnings in switch statements.
Eclipse does not pay attention to the second comment style.

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.

Any additional statements after the statement that is expected to
throw will never be executed in a passing test. This can lead to
inappropriately passing tests where later incorrect assertions are
skipped by the thrown exception. See [1] for examples.
There are no cases of this in the code base, but by enabling the
checker with severity ERROR we can ensure that we don't overlook
any future misuse of ExpectedException.

upload-pack protocol to not filter objects explicitly specified in

Propagating more information from the manifest to the superproject
tends to work out well. These particular settings mean:
Recording the remote branch in .gitmodules allows
- "git submodule update --remote" to fetch the right branch
- Gerrit's submodule subscription feature to subscribe from the
right branch, if requested
Recording groups in .gitattributes allows commands like "git clone
--recurse-submodules=:(attr:platform-linux) $superproject" to clone
the correct set of projects.
Recording the shallow bit in .gitmodules means that "git clone
--recurse-submodules" will use shallow clone in submodules where that
was requested in the manifest.
Gerrit's supermanifest plugin records the remote branch and shallow
bit by default already, and most users of that plugin configure it to
record groups in .gitattributes as well, so for most users this will
be a no-op.

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
verifies this case. The needless directory deletion and reporting
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/ .)
