In a distributed setting, one can have multiple datacenters use
reftables for serving, while the ground truth for the Ref database is
administered centrally. In this setting, replication delays combined
with compaction can cause update-index ranges to overlap.
Such a setting is used at Google, and the JGit code already handles

Add a GpgSignatureVerifier interface, plus a factory to create
instances thereof that is provided via the ServiceLoader mechanism.
Implement the new interface for BouncyCastle. A verifier maintains
an internal LRU cache of previously found public keys to speed up
verifying multiple objects (tag or commits). Mergetags are not handled.
Provide a new VerifySignatureCommand in org.eclipse.jgit.api together
with a factory method Git.verifySignature(). The command can verify
signatures on tags or commits, and can be limited to accept only tags
or commits. Provide a new public WrongObjectTypeException thrown when
the command is limited to either tags or commits and a name resolves
to some other object kind.
In jgit.pgm, implement "git tag -v", "git log --show-signature", and
"git show --show-signature". The output is similar to command-line
gpg invoked via git, but not identical. In particular, lines are not
prefixed by "gpg:" but by "bc:".
Trust levels for public keys are read from the keys' trust packets,
not from GPG's internal trust database. A trust packet may or may
not be set. Command-line GPG produces more warning lines depending
on the trust level, warning about keys with a trust level below
"full".
There are no unit tests because JGit still doesn't have any setup to
do signing unit tests; this would require at least a faked .gpg
directory with pre-created key rings and keys, and a way to make the
BouncyCastle classes use that directory instead of the default. See
bug 547538 and also bug 544847.
Tested manually with a small test repository containing signed and
unsigned commits and tags, with signatures made with different keys
and made by command-line git using GPG 2.2.25 and by JGit using
BouncyCastle 1.65.

DateRevQueue is expected to give out the commits that have higher
commit time. But in case of tie(same commit time), it should give
the commit that is inserted first. This is inferred from the
testInsertTie test case written for DateRevQueue. Also that test
case, right now uses just two commits which caused it not to fail
with the current implementation, so added another commit to make
the test more robust.
By fixing the DateRevQueue, we would also match the behaviour of
LogCommand.addRange(c1,c2) with git log c1..c2. A test case for
the same is added to show that current behaviour is not the
expected one.
By fixing addRange(), the order in which commits are applied during
a rebase is altered. Rebase logic should have never depended upon
LogCommand.addRange() since the intended order of addRange() is not
the order a rebase should use. So, modify the RebaseCommand to use
RevWalk directly with TopoNonIntermixSortGenerator.
Add a new LogCommandTest.addRangeWithMerge() test case which creates
commits in the following order:
A - B - C - M
\ /
-D-
Using git 2.30.0, git log B..M outputs: M C D
LogCommand.addRange(B, M) without this fix outputs: M D C
LogCommand.addRange(B, M) with this fix outputs: M C D

Reachability checkers are retrieved from RevWalk and ObjectWalk objects:
* RevWalk.createReachabilityChecker()
* ObjectWalk.createObjectReachabilityChecker()
Since RevWalks and ObjectWalks are themselves directly instantiated
in hundreds of places (e.g. UploadPack...) overriding them in a
consistent way requires overloading 100s of methods, which isn't
feasible. Moving reachability checker generation to a more central
place solves that problem.
The ObjectReader object seems a good place from which to get
reachability checkers, because reachability checkers return
information about relationships between objects. ObjectDatabases
delegate many operations to ObjectReaders, and reachability bitmaps
are attached to ObjectReaders.
The Bitmapped and Pedestrian reachability checker objects were
package private in the org.eclipse.jgit.revwalk package. This change
makes them public and moves them to the
org.eclipse.jgit.internal.revwalk package. Corresponding tests are
also moved.
Motivation:
1) Reachability checking algorithms need to scale. One of the
internal Android repositories has ~2.4 million refs/changes/*
references, causing bad long tail performance in reachability
checks.
2) Reachability check performance is impacted by repository
topography: number of refs, number of objects, amounts of
related vs. unrelated history.
3) Reachability check performance is also affected by per-branch
access (Gerrit branch permissions) since different users can
see different branches.
4) Reachability check performance isn't affected by any state in a
RevWalk or ObjectWalk.
I don't yet know if a single algorithm will work for all cases in #2
and #3. We may need to evolve the ReachabilityChecker interfaces
over time to solve the Gerrit branch permissions case, or use
Gerrit-specific identity information to solve that in an efficient
way.
This change takes the existing public API and moves it to the
ObjectReader/whole repository level, which is where we can do
consistent customizations for #2 and #3. We intend to upstream the
best of whatever works, but anticipate the need for multiple rounds
of experimentation.

Compare getting all refs except specific refs with seek and with filter
Add getsRefsByPrefixWithSkips (excluding prefixes) to ReftableDatabase
Add seekPastPrefix method to RefCursor
We sometimes want to get all the refs except specific prefixes,
similarly to getRefsByPrefix that gets all the refs of a specific
prefix.
We now create a new method that gets all refs matching a prefix except a
set of specific prefixes.
One use-case is for Gerrit to be able to get all the refs except
refs/changes; in Gerrit we often have lots of refs/changes, but very
little other refs. Currently, to get all the refs except refs/changes we
need to get all the refs and then filter the refs/changes, which is very
inefficient. With this method, we can simply skip the unneeded prefix so
that we don't have to go over all the elements.
RefDirectory still uses the inefficient implementation, since there
isn't a simple way to use Refcursor to achieve the efficient
implementation (as done in ReftableDatabase).

This method will be used by the follow-up change. This useful if we want
to go over all the changes after a specific ref.
For example, the new method allows us to create a follow-up that would
go over all the refs until we reach a specific ref (e.g refs/changes/),
and then we use seekPastPrefix(refs/changes/) to read the rest of the refs,
thus basically we return all refs except a specific prefix.
When seeking past a prefix, the previous condition that created the
RefCursor still applies. E.g, if the cursor was created by
seekRefsWithPrefix, we can skip some refs but we will not return refs
that are not starting with this prefix.

If the caller knows already HTTP Basic authentication will be needed
and if it also already has the username and password, preemptive

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.

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.

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

This reverts commit 022b02dea1.
Removing this API warning filter was wrong since we intentionally
removed the config constant CONFIG_REFSTORAGE_REFTREE.

File#list can return null. Fix the potential NPE by using Files#list
which is also faster since it retrieves directory entries lazily while
File#list retrieves them eagerly.

The ObjectDirectory class manages the interactions for the entire object
database, this includes loose objects, packfiles, alternates, and
shallow commits. To help reduce the complexity of this class, abstract
some of the loose object specific details into a class which understands
just this, leaving the ObjectDirectory to focus more on the interactions
between the different mechanisms.

Some clients may wish to allow NO_CHANGE lightweight tag updates
without setting the force flag. (For instance EGit does so.)
Command-line git does not allow this.
Propagate the RefUpdate result via the RefAlreadyExistsException.
That way a client has the possibility to catch it and check the
failure reason without having to parse the exception message, and
take appropriate action, like ignoring the exception on NO_CHANGE.

JGit treated a NO_CHANGE RefUpdate as an error in all cases. But when
updating a lightweight tag, this is a successful result if -f was
specified.

Add the two config constants from C git that can switch on signing
of annotated tags. Add them to the GpgConfig, and implement actually
signing a tag in TagCommand.
The interactions between command line options for "git tag" and config
options is a bit murky in C git. There are two config settings for it:
* tag.gpgSign is the main option, if set to true, it kicks in if
neither -s nor -u are given on the command line.
* tag.forceSignAnnotated signs only tags created via "git tag -m",
but only if command-line option "-a" is not present. It applies
even if tag.gpgSign is set explicitly to false.
Giving -s or -u on the command line also forces an annotated tag
since lightweight tags cannot be signed.

Factor out a common ObjectBuilder as super class of CommitBuilder
and TagBuilder, and make the GpgSigner work on ObjectBuilder.
In order not to break API, add the new method for signing an
ObjectBuilder in a new interface GpgObjectSigner.
The signature for a tag is just tacked onto the end of the tag
message. The message of a signed tag must end in LF.
