Some embeddings of JGit require creating a ReceivePack instance in
another process from the one that handled the network socket with the
client. Similar to the PushCertificate add a setter to allow the
option list to be supplied.
Change-Id: I303a30e54942ad067c79251eff8b53329c406628
Refactor all of the push option support code to allocate the list
immediately before parsing the options section off the stream.
Move option support down to ReceivePack instead of BaseReceivePack.
Push options are specific to the ReceivePack protocol and are not
likely to appear in the 4 year old subscription proposal. These
changes are OK before JGit 4.5 ships as no consumer should be relying
on these new APIs.
Change-Id: Ib07d18c877628aba07da07cd91875f918d509c49
Initialize pushOptions when we decide to use them, instead of when we
advertise them.
In the case of HTTP the advertisement is in a different network
request, hence in a different instance of the BaseReceivePack.

Do not open an OBJ_TREE if the caller is expecting an OBJ_BLOB or

DfsRefDatabase#compareAndPut had a vague semantics for reference
matching. Because of this, an operation to make a symbolic
reference had been broken for some DFS implementations even if they
followed the contract of compareAndPut. The clarified semantics
requires the implementations to satisfy the followings:
* Matching references should be both symbolic references or both
object ID references.
* If both are symbolic references, both should have the same target
name.
* If both are object ID references, both should have the same object
ID.
This semantics is defined based on
https://git.eclipse.org/r/#/c/77416/. Before this commit,
DfsRefDatabase couldn't see the target of symbolic references.
InMemoryRepository is changed to comply with the new semantics. This
semantics change can affect the existing DFS implementations that only
checks object IDs. This commit adds two tests that the previous
InMemoryRepository couldn't pass.

A JUnit TestRule which enables to run the same JUnit test repeatedly.
This may help to identify the root cause why a flaky tests which succeed
most often does fail sometimes.
Add the RepeatRule to the test class containing the test to be repeated:
public class MyTest {
@Rule
public RepeatRule repeatRule = new RepeatRule();
...
}
and annotate the test to be repeated with the @Repeat(n=<repetitions>)
annotation:
@Test
@Repeat(n = 100)
public void test() {
...
}
then this test will be repeated 100 times. If any test execution fails
test repetition will be stopped.

When doing a detaching operation, JGit fakes a SymbolicRef as an
ObjectIdRef. This is because RefUpdate#updateImpl dereferences the
SymbolicRef when updating it. For example, assume that HEAD is
pointing to refs/heads/master. If I try to make a detached HEAD
pointing to a commit c0ffee, RefUpdate dereferences HEAD as
refs/heads/master first and changes refs/heads/master to c0ffee. The
detach argument of RefDatabase#newUpdate avoids this dereference by
faking HEAD as ObjectIdRef.
This faking is problematic for the linking operation of
DfsRefDatabase. It does a compare-and-swap operation on every
reference change because of its distributed systems nature. If a
SymbolicRef is faked as an ObjectRef, it thinks that there is a
racing change in the reference and rejects the update. Because of
this, DFS based repositories cannot change the link target of symbolic
refs. This has not been a problem for file-based repositories because
they have a file-lock based semantics instead of the CAS based one.
The reference implementation, InMemoryRepository, is not affected
because it only compares ObjectIds.
When [1] introduced this faking code, there was no way for RefUpdate
to distinguish the detaching operation. When [2] fixed the detaching
operation, it introduced a detachingSymbolicRef flag. This commit uses
this flag to control whether it needs to dereference the symbolic refs
by calling Ref#getLeaf. The same flag is used in the reflog update
operation.
This commit does not affect any operation that succeeds currently. In
some DFS repository implementations, this fixes a ref linking
operation, which is currently failing.

Imitate the packet tracing feature from C Git v1.7.5-rc0~58^2~1 (add
packet tracing debug code, 2011-02-24). Unlike C Git, use the log4j
log level setting instead of the GIT_TRACE_PACKET environment variable
to enable tracing.
Tested as follows:
1. Enable tracing by adding the lines
log4j.logger.org.eclipse.jgit.transport=DEBUG, stderr
log4j.additivity.org.eclipse.jgit.transport=false
to org.eclipse.jgit.pgm/resources/log4j.properties.
2. mvn package
3. org.eclipse.jgit.pgm/target/jgit \
ls-remote git://git.kernel.org/pub/scm/git/git 2>&1 |less
Then the output provides a trace of packets sent and received over
the wire:

Unless the user passed --push-option, the client does not intend to
pass push options to the server.
Without this change, all pushes to servers without push option support
fail.
Not enabling the feature (instead of enabling it and sending an empty
list of options) in this case is more intuitive and matches the
behavior of C git push's --push-option parameter better.

This fixes the tests failed in JDK8.
FS uses java.nio API to get file attributes. The timestamps obtained
from that API are more precise than the ones from
java.io.File#lastModified() since Java8.
This difference accidentally makes JGit detect newly added files as
smudged. Use the precised timestamp to avoid this false positive.

The git-lfs specification [1] describes the following optional status codes
that may be returned:
429 - The user has hit a rate limit with the server. Though the API does
not specify any rate limits, implementors are encouraged to set some
for availability reasons.
509 - Returned if the bandwidth limit for the user or repository has been
exceeded. The API does not specify any bandwidth limit, but implementors
may track usage.
Add two new exception classes to represent these cases. Implementations may
throw these from #getLargeFileRepository(), causing the corresponding HTTP
status codes to be returned to the client.

OpenJDK replaces the underlying OutputStream with NullOutputStream when
the process exits. This throws IOException for all write operation. When
it exits before JGit writes the input to the pipe buffer, the input
stays in BufferedOutputStream. The close method tries to write it again,
and IOException is thrown.
Since we ignore IOException in StreamGobbler, we also ignore it when
we close the stream.
Fixes Bug 499633.
