Implement LfsProtocolServlet handling the "Git LFS v1 Batch API"
protocol [1]. Add a simple file system based LFS content store and the
debug-lfs-store command to simplify testing.
Introduce a LargeFileRepository interface to enable additional storage
implementation while reusing the same protocol implementation.
At the client side we have to configure the lfs.url, specify that
we use the batch API and we don't use authentication:
[lfs]
url = http://host:port/lfs
batch = true
[lfs "http://host:port/lfs"]
access = none
the git-lfs client appends the "objects/batch" to the lfs.url.
Hard code an Authorization header in the FileLfsRepository.getAction
because then git-lfs client will skip asking for credentials. It will
just forward the Authorization header from the response to the
download/upload request.
The FileLfsServlet supports file content storage for "Large File
Storage" (LFS) server as defined by the Github LFS API [2].
- upload and download of large files is probably network bound hence use
an asynchronous servlet for good scalability
- simple object storage in file system with 2 level fan-out
- use LockFile to protect writing large objects against multiple
concurrent uploads of the same object
- to prevent corrupt uploads the uploaded file is rejected if its hash
doesn't match id given in URL
The debug-lfs-store command is used to run the LfsProtocolServlet and,
optionally, the FileLfsServlet which makes it easier to setup a
local test server.

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

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();
}
Change-Id: I418e7e7d76422dc6f010d0b3b624d7bec3b20c6e
Provide static registerFormat and unregisterFormat methods to allow
formats to register themselves without the ArchiveCommand code being
aware of them.
Register the basic "zip" and "tar" support at bundle activation time
(and deregister them when unloading the bundle). For anyone using
this code as an OSGi plugin it should continue to just work.
The jgit program does not load org.eclipse.jgit.pgm as an OSGi bundle,

The most important difference is that in Java7 we have symbolic links
and for most operations in the work tree we want to operate on the link
itself rather than the link target, which the old File methods generally
do.
We also add support for the hidden attribute, which only makes sense
on Windows and exists, just since there are claims that Files.exists
is faster the File.exists.
A new bundle is only activated when run with a Java7 execution
environment. It is implemented as a fragment.
Tycho currently has no way to conditionally include optional features
based on the java version used to run the build, this means with this
change the jgit packaging build always needs to be run using java 7.

This breaks all existing callers once. Applications are not supposed
to build against the internal storage API unless they can accept API
churn and make necessary updates as versions change.

A pack bitmap index is an additional index of compressed
bitmaps of the object graph. Furthermore, a logical API of the index
functionality is included, as it is expected to be used by the
PackWriter.
Compressed bitmaps are created using the javaewah library, which is a
word-aligned compressed variant of the Java bitset class based on
run-length encoding. The library only works with positive integer
values. Thus, the maximum number of ObjectIds in a pack file that
this index can currently support is limited to Integer.MAX_VALUE.
Every ObjectId is given an integer mapping. The integer is the
position of the ObjectId in the complete ObjectId list, sorted
by offset, for the pack file. That integer is what the bitmaps
use to reference the ObjectId. Currently, the new index format can
only be used with pack files that contain a complete closure of the
object graph e.g. the result of a garbage collection.
The index file includes four bitmaps for the Git object types i.e.
commits, trees, blobs, and tags. In addition, a collection of
bitmaps keyed by an ObjectId is also included. The bitmap for each entry
in the collection represents the full closure of ObjectIds reachable
from the keyed ObjectId (including the keyed ObjectId itself). The
bitmaps are further compressed by XORing the current bitmaps against
prior bitmaps in the index, and selecting the smallest representation.
The XOR'd bitmap and offset from the current entry to the position
of the bitmap to XOR against is the actual representation of the entry
in the index file. Each entry contains one byte, which is currently
used to note whether the bitmap should be blindly reused.

The Apache Commons Compress library provides a similar interface to
java.util.zip with some features not found in java.util.zip, including
support for inclusion of metadata (file mode and symlink targets) and
support for multiple file formats (zip, .tar.xz, etc).
Use it, in preparation for making use of these features. No
functional change intended yet.
A previous version of this patch used plexus-archiver. That is a
heavier-weight dependency and offers a less convenient interface.
Thanks to James Moger and Chris Aniszczyk for advice.

This experiment proved to be not very useful. I had originally
planned to use this on top of Google Bigtable, Apache HBase or
Apache Cassandra. Unfortunately the schema is very complex and
does not perform well. The storage.dfs package has much better
performance and has been in production at Google for many months
now, proving it is a viable storage backend for Git.
As there are no users of the storage.dht schema, either at Google or
any other company, nor any valid open source implementations of the
storage system, drop the entire package and API from the JGit project.
There is no point in trying to maintain code that is simply not used.

The standard Google distribution of Protocol Buffers in Java is better
maintained than TinyProtobuf, and should be faster for most uses. It
does use slightly more memory due to many of our key types being
stored as strings in protobuf messages, but this is probably worth the
small hit to memory in exchange for better maintained code that is
easier to reuse in other applications.
Exposing all of our data members to the underlying implementation
makes it easier to develop reporting and data mining tools, or to
expand out a nested structure like RefData into a flat format in a SQL
database table.
Since the C++ `protoc` tool is necessary to convert the protobuf
script into Java code, the generated files are committed as part of
the source repository to make it easier for developers who do not have
this tool installed to still build the overall JGit package and make
use of it. Reviewers will need to be careful to ensure that any edits
made to a *.proto file come in a commit that also updates the
generated code to match.

jgit.storage.dht is a storage provider implementation for JGit that
permits storing the Git repository in a distributed hashtable, NoSQL
system, or other database. The actual underlying storage system is
undefined, and can be plugged in by implementing 7 small interfaces:
* Database
* RepositoryIndexTable
* RepositoryTable
* RefTable
* ChunkTable
* ObjectIndexTable
* WriteBuffer
The storage provider interface tries to assume very little about the
underlying storage system, and requires only three key features:
* key -> value lookup (a hashtable is suitable)
* atomic updates on single rows
* asynchronous operations (Java's ExecutorService is easy to use)
Most NoSQL database products offer all 3 of these features in their
clients, and so does any decent network based cache system like the
open source memcache product. Relying only on key equality for data
retrevial makes it simple for the storage engine to distribute across
multiple machines. Traditional SQL systems could also be used with a
JDBC based spi implementation.
Before submitting this change I have implemented six storage systems
for the spi layer:
* Apache HBase[1]
* Apache Cassandra[2]
* Google Bigtable[3]
* an in-memory implementation for unit testing
* a JDBC implementation for SQL
* a generic cache provider that can ride on top of memcache
All six systems came in with an spi layer around 1000 lines of code to
implement the above 7 interfaces. This is a huge reduction in size
compared to prior attempts to implement a new JGit storage layer. As
this package shows, a complete JGit storage implementation is more
than 17,000 lines of fairly complex code.
A simple cache is provided in storage.dht.spi.cache. Implementers can
use CacheDatabase to wrap any other type of Database and perform fast
reads against a network based cache service, such as the open source
memcached[4]. An implementation of CacheService must be provided to
glue this spi onto the network cache.
