org.eclipse.jgit.http.apache uses several features that exist only
since httpclient 4.4, but its MANIFEST.MF still had a lower bound of
4.3.0. Bump this to 4.4.0 for all packages from httpclient. 4.3.0 for
the packages from httpcore is fine.
Do a similar clean-up in the other bundles using packages from Apache
httpclient (http.test, lfs, lfs.server, lfs.server.test)

File#getParent can return null which caused this spotbugs warning.
FS.FileStoreAttributes#get already gets the parent directory if the
passed File is not a directory and checks for null. Hence there is no
need to get the parent directory in the FileSnapshot constructor.

If the caller knows already HTTP Basic authentication will be needed
and if it also already has the username and password, preemptive
authentication is a little bit more efficient since it avoids the
initial 401 response.
Add a setPreemptiveBasicAuthentication(username, password) method
to TransportHttp. Client code could call this for instance in a
TransportConfigCallback. The method throws an IllegalStateException
if it is called after an HTTP request has already been made.
Additionally, a URI can include userinfo. Although it is not
recommended to put passwords in URIs, JGit's URIish and also the
Java URL and URI classes still allow it. The underlying HTTP
connection may omit these fields though. If present, take these
fields as additional source for preemptive Basic authentication if
setPreemptiveBasicAuthentication() has not been called.
No preemptive authentication will be done if the connection is
redirected to a different host.
Add tests.

TransportHttp makes several HTTP requests. The SSLContext and socket
factory must be shared over these requests, otherwise authentication
information may not be propagated correctly from one request to the
next. This is important for authentication mechanisms that rely on
client-side state, like NEGOTIATE (either NTLM, if the underlying HTTP
library supports it, or Kerberos). In particular, SPNEGO cannot
authenticate on a POST request; the authentication must come from the
initial GET request, which implies that the POST request must use the
same SSLContext and socket factory that was used for the GET.
Change the way HTTPS connections are configured. Introduce the concept
of a GitSession, which is a client-side HTTP session over several HTTPS
requests. TransportHttp creates such a session and uses it to configure
all HTTP requests during that session (fetch or push). This gives a way
to abstract away the differences between JDK and Apache HTTP connections
and to configure SSL setup outside.
A GitSession can maintain state and thus give all HTTP requests in a
session the same socket factory.
Introduce an extension interface HttpConnectionFactory2 that adds a
method to obtain a new GitSession. Implement this for both existing
HTTP connection factories. Change TransportHttp to use the new
GitSession to configure HTTP connections.
The old methods for disabling SSL verification still exist to support
possibly external connection and connection factory implementations
that do not make use of the new GitSession yet.

Previously, TransportHttp always used the globally set connection
factory. This is problematic if that global factory is changed in
the middle of a fetch or push operation. Initialize the factory to
use in the constructor, then use that factory for all HTTP requests
made through this transport. Provide a setter and a getter for it
so that client code can customize the factory, if needed, in a
TransportConfigCallback.
Once a factory has been used on a TransportHttp instance it cannot
be changed anymore.
Make the global static factory reference volatile.

UploadPack may log ACKs in protocol V2 that it doesn't send (if it
got a "done" from the client), or may log ACKs twice. That makes
packet log analysis difficult.
Add a new constructor to PacketLineOut to omit all logging from an
instance, and use it in UploadPack.

The negotiation in the git protocol contains a cutoff: if the client
has sent more than MAX_HAVES "have" lines without getting an ACK, it
gives up and sends a "done". MAX_HAVES is 256.
However, this cutoff must kick in only if at least one ACK has been
received. Otherwise the client may give up way too early, which makes
the server send all its history. See [1].
This was missed when protocol V2 was implemented for fetching in JGit
in commit 0853a241.
Compare also C git commit 0b07eecf6ed.[2] C git had the same bug.[3][4]

Make all transports request protocol V2 when fetching. Depending on
the transport, set the GIT_PROTOCOL environment variable (file and
ssh), pass the Git-Protocol header (http), or set the hidden
"\0version=2\0" (git anon). We'll fall back to V0 if the server
doesn't reply with a version 2 answer.
A user can control which protocol the client requests via the git
config protocol.version; if not set, JGit requests protocol V2 for
fetching. Pushing always uses protocol V0 still.
In the API, there is only a new Transport.openFetch() version that
takes a collection of RefSpecs plus additional patterns to construct
the Ref prefixes for the "ls-refs" command in protocol V2. If none
are given, the server will still advertise all refs, even in protocol
V2.
BasePackConnection.readAdvertisedRefs() handles falling back to
protocol V0. It newly returns true if V0 was used and the advertised
refs were read, and false if V2 is used and an explicit "ls-refs" is
needed. (This can't be done transparently inside readAdvertisedRefs()
because a "stateless RPC" transport like TransportHttp may need to
open a new connection for writing.)
BasePackFetchConnection implements the changes needed for the protocol
V2 "fetch" command (stateless protocol, simplified ACK handling,
delimiters, section headers).
In TransportHttp, change readSmartHeaders() to also recognize the
"version 2" packet line as a valid smart server indication.
Adapt tests, and run all the HTTP tests not only with both HTTP
connection factories (JDK and Apache HttpClient) but also with both
protocol V0 and V2. The SSH tests are much slower and much more
focused on the SSH protocol and SSH key handling. Factor out two
very simple cloning and pulling tests and make those run with
protocol V2.

On Android, the co-variant override of ConcurrentHashMap.keySet()
introduced in Java 8 was undone. [1] If compiled Java code calls that
co-variant override directly, one gets a NoSuchMethodError exception
at run-time on Android.
Making the code call that method via Map.keySet() side-steps this
problem.
This is similar to bug 496262, where the same problem cropped up when
compiling with Java 8 against a Java 7 target, but here we cannot use
bootclasspath. We build against Java 8, not against the Android version
of it.
Recent Android versions should have some bytecode "magic" that adds the
co-variant override in bytecode (see the commit referenced in [1]), but
on older Android version this problem may still occur. (Or perhaps the
"magic" is ineffective...) There are two pull requests on Github for
this problem, both from 2020, [2][3] while the Android commit [1] is
from March 2018. Apparently people still occasionally run into this
problem in the wild.

Do not export the test-only package org.eclipse.jgit.transport from

up this test package, leading to non-test sources depending on test
sources and to build cycles.
