Sometime the new commit is no allocated onto a new lane leading to
the commit being drawn on the wrong branch and something that looks
like a merge.
The drawback is that this also changes existing valid graphs.

If we encounter an I/O error while writing an archive (for example due
to the reader of an HTTP stream closing the connection), the result is
an archive with unclosed entries, causing
TarArchiveOutputStream.finish() to throw IOException("This archives
contains unclosed entries"), hiding the IOException that caused the
early termination.
The unclosed entries are fine: the same exception that occured in the
first place will probably prevent closing the entries before finishing
this partial archive that should be discarded anyway.
It would be nicer to call TarArchiveOutputStream.finish and leave the
underlying OutputStream unclosed --- all callers close it already ---
but that would be a more invasive change so we hold off for now.

In C Git 1.8.2, "git reset" now also works on an unborn branch (no HEAD
yet) if no explicit ref was specified. In that case, it is treated as a
reset to an empty tree.
This can be useful for callers because "unborn branch" no longer has to
be special-cased to "git rm --cached".

OpenJDK 7 does not benefit from using an inflate stride on the input
array. The implementation of java.util.zip.Inflater supplies the
entire input byte[] to libz, with no regards for the bounds supplied.
Slicing at 512 byte increments in DfsBlock no longer has any benefit.
In OpenJDK 6 the native portion of Inflater used GetByteArrayRegion
to obtain a copy of the input buffer for libz. In this use case
supplying a small stride made sense, it avoided allocating space
for and copying data past the end of the object's compressed stream.
In OpenJDK 7 the native code uses GetPrimitiveArrayCritical,
which tries to avoid copying by freezing Java garbage collection
and accessing the byte[] contents in place. On OpenJDK 7 derived
JVMs it is likely more efficient to supply the entire DfsBlock.
Since OpenJDK 5 and 6 are deprecated and replaced by OpenJDK 7
it is reasonable to suggest any consumers running JGit with DFS
support use an OpenJDK 7 derived JVM. However, JGit still targets
local filesystem support on Java 5, so it is still not reasonble to
apply this same simplification to the internal.storage.file package.

The dash signing plugin has been retired hence we need to update our
build to use the CBI jarsigner plugin for signing build results.
Pack test classes to enable signing them.
Also re-enable pack200 for bundle org.eclipse.jgit.
WORKAROUND: there is no easy way to run tests with maven-surefire-plugin
from signed test-jar so for a quick workaround we will have to add a
build step on Hudson so that we can run tests before signing:
- first step will do "clean, verify" to compile and run tests
- second step will do "install, deploy" with profile "eclipse-sign" and
use -DskipTests=true to skip tests since they would hit a
SecurityException when unsigned test classes are in same package as
signed classes under test
- third step will do "clean, install, deploy" on packaging reactor to
build features and p2 repository with profile "eclipse-sign" to sign
and pack200 all bundles.
TODO: Tycho doesn't suport picking up pack200 artifacts via
pomDependencies hence we need to find a way to copy them manually and
use tycho-extra's tycho-p2-extras-plugin:publish-features-and-bundles
to generate the missing p2 metadata.

With reference hiding, it is possible for a repository to appear
empty when all refs are hidden. This causes capabilities to not be
advertised either, since they are published with the first reference,

Always advertise the capabilites by publishing the symbolic capabilities
reference when the repository has no references to advertise (similar to

Associate each RequestPolicy with an implementation of a
RequestValidator interface that contains the validation logic. The
checkWants method is only called if there are wants that were not
advertised, since clients may always request any advertised want
according to the git protocol. Calling the method only once at the
end of parsing the want list also means policy implementations can be
stateful, unlike the previous switch statement inside a loop.
For the special handling of unidirectional pipes, simply check
isBiDirectional() and delegate to other implementations if necessary.

C git 1.8.2 supports setting the equivalent of RequestPolicy.TIP with
uploadpack.allowtipsha1. Parse this into TransportConfig and use it
from UploadPack. An explicitly set RequestPolicy overrides the config,
and the policy may still be upgraded on a unidirectional connection to
avoid races.
Defer figuring out the effective RequestPolicy to later in the
process. This is a minor semantic change to fix a bug: previously,
calling setRequestPolicy(ADVERTISED) _after_ calling
setBiDirectionalPipe(true) would have reintroduced the race condition
otherwise fixed by 01888db892.

With this, CloneCommand now tries "$branch", then "refs/heads/$branch"

Allow use of ArchiveCommand without depending on the jgit command-line
tools.
To avoid complicating the process of installing and upgrading JGit,
this does not add a dependency by the org.eclipse.jgit bundle on
commons-compress. Instead, the caller is responsible for registering
any formats they want to use by calling ArchiveCommand.registerFormat.
This patch puts functionality that requires an archiver into a
separate org.eclipse.jgit.archive bundle for people who want it. One
can use it by calling ArchiveCommand.registerFormat directly to
register its formats or by relying on OSGi class loading to load
org.eclipse.jgit.archive.FormatActivator, which takes care of
registration automatically.
Once the appropriate formats are registered, you can make a tar or zip
from a git tree object as follows:
ArchiveCommand cmd = git.archive();
try {
cmd.setTree(tree).setFormat(fmt).setOutputStream(out).call();
} finally {
cmd.release();

If you look at any implementation of Comparable in the JDK, you'll see
that the type parameter for Comparable is supposed to be the type of
the implementing class:
http://docs.oracle.com/javase/6/docs/api/java/lang/Comparable.html
The current type signature of Comparable<Object> is pretty awful, at the
very least because you can not, in fact, successfully compare
AnyObjectId with any random subclass of Object. It also causes problems
with type-inference and the scala.math.Ordering trait in Scala.
In order to compile, this change *does* require removing the
AnyObjectId.ompareTo(Object) method - which actually only ever cast
to AnyObjectId in any case. Nothing in the JGit test suite requires this
method, but it might constitute a breaking API change, so it would be
best if it can be added in time for JGit 3.0.
