Any messages received on side band #2 that aren't scraped as a
progress message into our ProgressMonitor are now forwarded to a
buffer which is later included into the OperationResult object.
Application callers can use this buffer to present the additional
messages from the remote peer after the push or fetch operation
has concluded.
The smart push connections using the native send-pack/receive-pack
protocol now request side-band-64k capability if it is available
and forward any messages received through that channel onto this
message buffer. This makes hook messages available over smart HTTP,
or even over SSH.
The SSH transport was modified to redirect the remote command's
stderr stream into the message buffer, interleaved with any data
received over side band #2. Due to buffering between these two
different channels in the SSH channel mux itself the order of any
writes between the two cannot be ensured, but it tries to stay close.
The local fork transport was also modified to redirect the local
receive-pack's stderr into the message buffer, rather than going to
the invoking JVM's System.err. This gives applications a chance
to log the local error messages, rather than needing to redirect
their JVM's stderr before startup.
To keep things simple, the application has to wait for the entire
operation to complete before it can see the messages. This may
be a downside if the user is trying to debug a remote hook that is
blocking indefinitely, the user would need to abort the connection
before they can inspect the message buffer in any sort of UI built
on top of JGit.

We now advertise the side-band-64k capability inside of ReceivePack,
allowing hooks to echo status messages down the side band channel
instead of over the optional stderr stream.
This change permits hooks running inside of an http:// based push
invocation to still message the end-user with more detailed errors
than the small per-command string in the status report.

To avoid scraping a non-progress message as though it were a progress
item for the progress monitor, use a more restrictive pattern to
watch the remote side's messages. These two regexps should match
any message produced by C Git since 42e18fbf5f94 ("more compact
progress display", Oct 2007), and which first appeared in Git 1.5.4.

Typically we refer to the raw InputStream (the stream without the
pkt-line headers on it) as rawIn, and the pkt-line header variant
as pckIn. Refactor our fields to reflect that. To ensure these
are actually the same underlying InputStream, we now create our own
PacketLineIn wrapper around the supplied raw InputStream. Its a
very low-cost object since it has only the 4 byte length buffer.
Instead of hardcoding the header length as 5, use the constant from
SideBandOutputStream. This makes it a bit more clear what we are
consuming, exactly here.

Instead of relying on our callers to wrap us up inside of a
BufferedOutputStream and using the proper block sizing, do the
buffering directly inside of SideBandOutputStream. This ensures
we don't get large write-throughs from BufferedOutputStream that
might overflow the configured packet size.
The constructor of SideBandOutputStream is also beefed up to check
its arguments and ensure they are within acceptable ranges for the
current side-band protocol.

The initial contribution was handled through a CQ, and does not need

Its an odd corner case that the EMO IP team doesn't want to see,
even though its technically a contribution written by at least
some non-committers.
The project.skipCommit variable can now be used to mask out any

When implementing branch read access, we need to prove that the
newly created reference(s) point to objects that the user can see.
There are two ways that an object is reachable:
1) It's reachable from a branch or change the user can see
2) It was uploaded as part of the pack file the user sent us
This change adds additional methods in ReceivePack that will allow a
server to check the above conditions, in order to ensure that a user
is not trying to create a reference that they cannot see, or that a
malicious user isn't attempting to forge the SHA-1 of an object that
they cannot see in order to base a change off of it.

A 0 file mode in a DirCacheEntry is not a valid mode. To C git
such a value indicates the record should not be present. We already
were catching this bad state and exceptioning out when writing tree
objects to disk, but we did not fail when writing the dircache back
to disk. This allowed JGit applications to create a dircache file
which C git would not like to read.
Instead of checking the mode during writes, we now check during
mutation. This allows application bugs to be detected sooner and
closer to the cause site. It also allows us to avoid checking most
of the records which we read in from disk, as we can assume these
are formatted correctly.
Some of our unit tests were not setting the FileMode on their test
entry, so they had to be updated to use REGULAR_FILE.

A dircache record must not use a path string like "/a" or "a//b"
as this results in a tree entry being written with a zero length
name component in the record. C git does not support an empty name,
and neither does any modern filesystem.
A record also must not have a stage outside of the standard 0-3
value range, as there are only 2 bits of space available in the
on-disk format of the record to store the stage information.
Any other values would be truncated into this space, storing a
different value than the caller expected.
If an application tries to create a DirCache record with either of
these wrong values, we abort with an IllegalArgumentException.
