Adds a JGit built-in implementation of the "git lfs smudge" filter. This
filter should do the same as the one described in [1] besides that it
only supports the local case when the lfs objects are already present in
the media directory. Remote cases where download of LFS objects from an
LFS server is needed will be done in a later commit.

Adds a JGit built-in implementation of the "git lfs clean" filter. This

If the configuration parameter filter.<filterDriverName>.useJGitBuiltin
is set to true then for all corresponding filters JGit will try to
execute the built-in filter instead of the filter-command which is
defined in git configuration. It will fallback to the non-built-in
filters if no built-in filters are registered or if constructing them
leads to exceptions. If set to false JGit will not try to execute
built-in filters for the specified filter driver.
Example: The configuration contains the following lines
[filter "lfs"]
clean = git-lfs clean -- %f
smudge = git-lfs smudge -- %f
useJGitBuiltin = true
Addtionally the .gitattributes file in the root of the working tree
contains:
*.bin filter=lfs
In this case when new content is added similar to "git add 1.bin" then
the following will happen:
- jgit will check whether a built-in command factory was registered
for the command "jgit://builtin/lfs/clean". If that is true the
factory is used to create a built-in filter command and that
command is used to filter the content
- Otherwise jgit will call the external program "git lfs clean ..."
to do the filtering

JGit supports smudge filters defined in repository configuration. The
filters are implemented as external programs filtering content by
accepting the original content (as seen in git's object database) on
stdin and which emit the filtered content on stdout. This content is
then written to the file in the working tree. To run such a filter JGit
has to start an external process and pump data into/from this process.
This commit adds support for built-in smudge filters which are
implemented in Java and which are executed by jgit's main thread. When a
filter is defined in the configuration as
"jgit://builtin/<filterDriverName>/smudge" then JGit will lookup in a
static map whether a builtin filter is registered under this name. If
found such a filter is called to do the filtering.
The functionality in this commit requires that a program using JGit
explicitly calls the JGit API to register built-in implementations for
specific smudge filters. In follow-up commits configuration parameters
will be added which trigger such registrations.

BranchConfig treated this config property as a boolean, but git also
allows the values "preserve" and "interactive". Config property
pull.rebase also allows the same values.
Replace private enum PullCommand.PullRebaseMode by new public enum
BranchConfig.BranchRebaseMode and adapt all uses. Add a new setter to
PullCommand.
Note: PullCommand will treat "interactive" like "true", i.e., as a
non-interactive rebase. Not sure how "interactive" should be handled.
At least it won't balk on it.

This allows the same try/catch to handle parsing the command list,

Some embeddings of JGit require creating a ReceivePack instance in

client. Similar to the PushCertificate add a setter to allow the

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.

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.

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:
