This is public facing, stable API.
Fortunately, this class is deprecated and will be removed in the next
major version bump.

JSch prefers ssh-rsa key type. When the remote server supports ssh-rsa
key type then this key type will be used even if the known_hosts file
contains a host key for that host, but with different key type.
This caused an unexpected UnknownHostKey error.
To fix the issue first scan the known_hosts, the HostKeyRepository in
JSch API, for any already existing host keys for the target host and
modify the default session settings to prefer their algorithms. However,
do this only if there is no HostKeyAlgorithms setting active.

The code base has several @SuppressWarnings annotations to suppress
warnings raised by Error Prone, but those are not recognized by
Eclipse and there is currently no way to tell it about them [1].
Suppress them for now.

One more step in removing state from UploadPack, using the request
object instead.
Unfortunately, hooks get from UploadPack information about the current
request. Changing the hooks to receive the request is a public API
change, so at the moment lets keep a reference to the current request.
This kills half the benefit of using a request object vs fields, but
at least we still get better modularity.

All data required in this function is available in the request object.
Use that object instead of class members. This reduces class state and
is more readable.
Make the function use a request object and remove the now unnecessary
field "deepenNotRefs".

These properties are protocol v2 specific, but they have clear default
no-op values and having them in the common superclass simplifies client
code.
Move properties deepenSince and deepenNotRefs up to FetchRequest. In
FetchV0Request, they are initialized with their no-op values (0 for
deepenSince and empty list for deepenNotRefs)

filterBlobLimit is not part of the UploadPack state, and as field
of the class is difficult to see where it is set or accessed.
Use the request object instead of a field. This reduces
UploadPack state and makes clearer how the value is used.

In FetchV0Request, the fields "wantsIds" and "options" are called
"wantIds" and "clientCapabilities". Those names describe them better.
Rename FetchV2Request fields to follow fetch v0. This will make easier
to extract a superclass later.

Protocol v0/v1 parsing code doesn't have any real dependency on UploadPack.
Move it to its class and use a request object to read the data in
UploadPack.
This makes the code easier to test, keeps similar structure than protocol v2,
reduces the line count of UploadPack and paves the way to remove the
members as implicit parameters in it.

Uncaught exceptions are handled by java.lang.Thread's handler, which
prints it to stderr.
This is useful because InternalPushConnection is used in tests, and
during development, the server side may have programming errors that
manifest as RuntimeExceptions.
Before this change, all types of failures would lead to a uniform
failure message "test://test/conn0: push not permitted" on the client.

In protocol v0/v1 pack negotiation, the first want line contains the
options the client wants in effect. This parsing is done in UploadPack
but it doesn't have any interaction with that class.
Move the code to its own class and package, mark the current one
as deprecated (it is public API) and add unit tests.
Take the chance to move the parsing code from the constructor to a
factory method, making the class a simple container of results.

use

This makes the style more consistent (the existing JGit code base
tends to lean toward the second style) and makes the source code

As described in the javadoc for org.eclipse.jgit.annotations.Nullable:
Warning: Please do not use this annotation on arrays. Different
annotation processors treat `@Nullable Object[]` differently: some
treat it as an array of nullable objects, for consistency with
versions of `Nullable` defined with `@Target TYPE_USE`, while others
treat it as a nullable array of objects. JGit therefore avoids using
this annotation on arrays altogether.

A .gitmodules file can include a submodule without a path to configure
the URL for a submodule that is only present on other branches.
A .gitmodules file can include a submodule with no URL and no path to
reserve the name for a submodule that existed in earlier history but
is not available from any URL any more.
"git fsck" permits both of these cases. Permit them in JGit as well
(instead of throwing NullPointerException).

In order to validate .gitmodules files, we first need to find them
in the incoming pack.
Do it in the ObjectChecker stage. Check in the tree objects if they
point to a .gitmodules file and report the tree id and the .gitmodules
blob id.
This can be used later to check if the file is in the root of the
project and if the contents are good.
While we're here, make isMacHFSGit more accurate by detecting variants
of filenames that vary in case.
