Frequently enough I'm wondering how much of a pack is commits vs.
trees, and the total line doesn't really tell us this because its
a gross total from the pack. Computing the counts per object type
is simple during packing, as PackWriter already has everything in
memory broken up by object type. Its virtually free to get these
values and track them.

Simple variant of addAll() that knows how to copy large segments
quickly using System.arraycopy() rather than looping through with
an Iterator object.

Instead of computing this on every request, compute it once and
hold onto the result. This improves performance for LocalCachedPack
which does a lot of tests against the pack name string.

In case a file needs to be checked out (from THEIRS) during a merge
operation, it has to be checked if the worktree version of this file
is dirty. If this is true, merge shall fail.

1. Perform an explicit check for untracked files.
2. Extract 'dirty checks' into separate methods
3. Clean up comments.
4. Tests: also check contents of files not affected by merge.

We test the -o option of the commit command very accurate by
writing tests for each line of a decision table. In order to
still be able to point new jgit users to the CommitAndLogCommandTest
to find out how to use log() and commit() I factored out these 1200
lines of very specific tests into their own class.

When fetching from a remote peer, consider all of the refs of any
alternate repository to be reachable locally, in addition to the refs
of the local repository. This mirrors the push protocol and may avoid
unnecessary object transfer when the local repository is empty, but
its alternate and the remote share a lot of common history.
Junio C Hamano recently proposed a similar change to C Git's fetch
client, in order to work around a performance bug I identified when
fetching between two repositories that actually shared the same
alternate repository on the local system.

Instead of aborting hard with a server-side exception, report an error
to the client with "ERR %s" in a context where the client is expecting
ACK/NAK. Older clients will report this text to the user, but newer
ones know how to format this message in a more user-friendly way.

If the remote peer replies with "ERR %s" instead of "ACK %s common" or
"NAK" during ancestor negotiation in the fetch-pack/upload-pack
protocol, treat that as an exception that aborts processing with the
error text as supplied by the remote system.
This matches behavior with "ERR %s" during the advertisements, which
is also a way for the remote to abort processing.

Most "ACK %s continue", "ACK %s common", "NAK" strings that are read
by the readACK() method and readString() are shorter than the
lineBuffer already available. Reuse that buffer when reading from
the network stream and converting to a string with RawParseUtils to
avoid unnecessary temporary byte array allocations.

If no directory is set before executing an InitCommand, the current
directory (".") is used by default. By calling File.getParentFile() we
get the actual directory this points to. Using this directory makes it
easier to read paths.

For compatibility reasons with regards to native git and also to
make the init command easier to use from the command line,
argument --git-dir should not be required.
Additionally the path created in case --git-dir is not supplied now is
canonical and thus easier to read.

If the client is only following the remote repository and has not
created any new non-common commits, the client will wind up sending
a "have %s" line for each tag in the repository. For some projects
like git.git, this is 339 tags and growing, resulting in more than
16 KiB needing to be POSTed over 12 HTTP requests.
Teach UploadPack (server side) to always execute the okToGiveUp()
logic at least once per negotiation round to determine if the server
can compute a pack right now. If it can, shove in an "ACK %s ready"
message to tell the client this and try to prevent receiving ancient
tags in future negotiation rounds.
Teach BasePackFetchConnection (client side) to honor a "ACK %s ready"
from the remote and break out of its SEND_HAVE loop once the remote
knows it can create a pack. This avoids sending the remaining 307
tags of git.git.
These two changes together reduce the number of HTTP RPCs from 13
down to 3 in order to fetch from git.git over smart HTTP. If either
side is missing the change, the older behavior (and its 13 RPCs)
is used.

PackWriter incorrectly returned 0 from getObjectsNumber() when the
pack has not been written yet. This caused dumb transports like
amazon-s3:// and sftp:// to abort early and never write out a pack,
under the assumption that the pack had no objects.
Until the pack header is written to the output stream, compute the
current object count each time it is requested. Once the header is
started, use the object count from the stats object.
