It can be useful for a server operator to know how long a pack
writer spent writing out objects, even if the request aborts and
never finishes.
Record more of the stats data inside of a finally block, to
ensure these can be included into the server's monitoring.

This was a copy-artifact when the bundle was created. This chanhe
removed some warnings in Eclipse.

Some of these eliminations just reduces the number of warnings on
lines where messages are constructed that can/will be translated.

If the git server requires authentication and no CredentialsProvider is
registered TransportHttp.connect() would throw an NPE since it tries to
reset the credentials provider. Instead throw a TransportException
explaining the problem.

If the packer fails, still obtain the stats and make them available
to the logger and the caller. Failures can frequently happen when
a client disconnects in the middle of a pack stream. Server admins
may still want to examine the timing metrics from counting and
compressing phases.

uninteresting
Using the ObjectWalk and marking a commit as uninteresting didn't mark
its root tree as uninteresting. This caused the "missing tree ..."
error in Gerrit under special circumstances. For example, if the
patch-set 2 changes only the commit message then the patch-set 1
and patch-set 2 share the same root-tree:
ps1 -> o o <- ps2
\ /
o root-tree
The transported pack will contain the ps2 commit but not the root-tree
object.
When using the BaseReceivePack.setCheckReferencedObjectsAreReachable
JGit will check the reachability of all referenced objects not provided
in the transported pack. Since the ps1 was advertised it will properly
be marked as uninteresting. However, the root-tree was reachable because
the ObjectWalk.markUninteresting missed to mark it as uninteresting.
JGit was then rejecting the pack with the "missing tree ..." exception.

In Git 1.9 (5dbd767601 "support pushing from a shallow clone")
the git-core project intentionally broke the existing send-pack
protocol from shallow clients.
Shallow clients now transmit their shallow information during push,
ahead of the old-new command sequence. JGit must accept these lines
when presented.
To protect the server against clients sending partial history,
require the connectivity check when pushed to by a shallow client.

the associated ObjectInserter when the merger is a RecursiveMerger
instance and a virtual common base was constructed but not flushed.

The native implementation of inflate() can set finished to return
true at the same time as it copies the last bytes into the buffer.
Check for finished on each iteration, terminating as soon as libz
knows the stream was completely inflated.
If not finished, it is likely input is required before the next
native call could do any useful work. Most invocations are passing
in a buffer large enough to store the entire result. A partial return
from inflate() will need more input before it can continue. Checking
right away that needsInput() is true saves a native call to determine
no bytes can be inflated without more input.
This should fix a rare infinite loop condition inside of inflation
when an object ends exactly at the end of a block boundary, and
the next block contains only the 20 byte trailing SHA-1.
When the stream is finished each new attempt to inflate() returns
n == 0, as no additional bytes were output. The needsInput() test
tries to add the length of the footer block to itself, but then loops
back around an reloads the same block as the block is smaller than
a full block size. A zero length input is set to the inflater,
which triggers needsInput() condition again.

This reverts commit b646578d89.
openInputStream() is never used in JGit, nor is it used by any
known working DFS implementation. The method was added as a
utility for reading back from a DfsInserter, but the final
implementation of that feature does not requrire this method.

This allows callers performing multiple separate merges to reuse a
single ObjectInserter without flushing the inserter on each iteration
(which can be slow in the DFS case).

This allows the RecursiveMerger to iteratively create new merge bases
without necessarily flushing packs to storage in the DFS case;
flushing only need happen at the end of the whole merge process.
Since Merger's walk now depends on its inserter, we need to construct
an inserter at Merger construction time. This should not be a
significant increase in overhead since unused inserters don't use any
resources (beyond a reference to the Repository).
We also must release and recreate the walk whenever setObjectInserter
is called, which can break usages where setObjectInserter is called in
the middle of stateful operations on the walk. No usages of this
method within JGit currently do this; the inserter is only ever set
before any stateful walk operations happen.

In the DFS implementation, flushing an inserter writes a new pack to
the storage system and is potentially very slow, but was the only way
to ensure previously-inserted objects were available. For some tasks,
like performing a series of three-way merges, the total size of all
inserted objects may be small enough to avoid flushing the in-memory
buffered data.
DfsOutputStream already provides a read method to read back from the
not-yet-flushed data, so use this to provide an ObjectReader in the
DFS case.
In the file-backed case, objects are written out loosely on the fly,
so the implementation can just return the existing WindowCursor.

Since 2badedcbe0 in-core merges can write up to 10 MiB
into a TemporaryBuffer.Heap strategy, where the data is stored
as a chain of byte[] blocks.
Support the inserter reading up to the streamFileThreshold (default 50
MiB) from the supplied input stream and hash the content to determine
if the merged result blob is already present in the repository. This
allows the inserter to avoid creating duplicate objects in more cases,
reducing repository pack file churn.

The base Merger class already has a single ObjectReader instance that
it handles releasing as necessary, so creating new readers is not
necessary.
