The first step to deleting a repository from the DHT storage is to
remove the name binding in the RepositoryIndexTable, making the
repository unavailable for lookup.

If the command is either `diff` or `log`, there is often a lot of
lines of output. Run these commands through $GIT_PAGER, $PAGER, or
`less` in order to make it easier to browse the output on a terminal.

There is no reason for this type to contain an ArrayList and try to
hide the implementation. It only slows down execution by adding an
extra layer of method dispatch to each invocation.
Instead subclass from ArrayList.

Some servlet containers require the servlet to read the EOF marker
from the input stream before a response can be output if the stream
is using "Transfer-Encoding: chunked"... which is typical for any
sort of large push to a repository over smart HTTP.
Ensure the EOF is always read by the PackParser when it is handling
the stream, and fail fast if there is more data present than expected
since this does indicate a protocol error.
Also ensure the EOF is read by UploadPack before it starts to output
a partial response using packing progress meters.

Some repositories created during tests are not added to the 'toClose'
list in LocalDiskRepositoryTestCase. Therefore when the tests end
we may have open FileHandles and on Windows this may cause the
tests to fail because we can't delete those files.
This is fixed by adding the possibility to explicitly add
repositories to the list of repos which are closed automatically.

When cloning into a bare repository we should not create remote
tracking branches (e.g refs/remotes/origin/testX). Branches of the
remote repository should but fetched into into branches of the same
name (e.g refs/heads/testX). Also add the noCheckout option which
would prevent checkout after fetch.

is fixed with this commit. Additionally the constructors for the
different types of refs have been changed to take a FileSnapshot
instead of a modification time.

RefData now uses a sequence number as part of the field, ensuring
that updates always increase the sequence number by one whenever
a reference is modified.
Attaching a sequence number to RefData will help with storing
reference log entries during updates. As the sequence number should
be unique within the reference name space, log entries can be keyed
by the sequence number and remain unique. Making this work over
reference delete-create cycles will require an additional RefTable
API to return the oldest sequence number previously used in the
reference log to seed the recreated reference.

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.

Performance testing has indicated the per-process ChunkCache isn't
very effective for the DHT storage implementation. If a server is
using the DHT storage backend, it is most likely part of a larger
cluster where requests are distributed in a round-robin fashion
between the member servers.
In such a scenario there is insufficient data locality between
requests to get a good hit ratio on the per-process ChunkCache. A low
hit ratio means the cache is actually hurting performance by eating up
memory that could otherwise be used for transient request data, and
increasing pressure on the GC when it needs to find free space.
Remove all of the ChunkCache code. Installations that want to cache
(to reduce database usage) should wrap their Database with a
CacheDatabase and use a network based CacheServer.
I left the ChunkCache in the original DHT storage commit because I
wanted to document in the history of the project that its probably
worth *not* having, but leave open a door for someone to revert this
change if they find otherwise at a later date.

Since this change may affect performance and memory consumption on every
access to a loose ref I explicitly made it a RFC to collect opinions.
Previously RefDirectory.scanRef() was not detecting an update of a
loose ref when the update didn't changed the modification time of
the backing file. RefDirectory cached loose refs and the way to detect
outdated cache entries was to compare lastmodification timestamp on the
file representing the ref. If two updates to the same ref happen faster
than the filesystem-timer granularity (for linux this is 2 seconds)
there is the possiblity that we don't detect the update.
Because of this bug EGit's PushOperationTest only works with 2 second
sleeps inside.
This change let RefDirectory use FileSnapshot to detect such situations.
FileSnapshot helps to remember when a file was last read from disk and
therefore enables to decide when to load a file from disk although
modification time has not changed.

Previously when merging two contents with a non-empty base and one of
the contents was empty (size == 0) and the other was modified there
was a potentially expensive calculation until we finally always come
to the same result -> the complete non-deleted content should collide
with the empty content.
This proposal adds an optimization to detect empty input content and
to produce the appropriate result immediatly.
