LockFileTest was failing on Windows because we couldn't delete the lock
file of the index. The reason was that a LockFile instance still had an
open handle to the lock file preventing us to delete the file (in
contrast to the behavior on other platforms).

It is not always appropriate to use the .gitmodules file from the
working tree, for example if reading the modules at a specific commit.
And sometimes it is impossible, as in a bare repository.
When using the static factory methods, automatically set up the
appropriate root tree so lazy loading of the config file reads from
the appropriate place. Leave the current behavior of looking in the
working tree as a fallback for the case where walking the index.

Relax the read() method to not block until exactly "len" bytes have
been read. Instead, return when one or more bytes have been read, up
to "len", so UnionInputStream more closely resembles InputStream's
read() method.

PackWriter supports excluding objects from being written to the pack.
You may specify a PackIndex which lists all those objects which should
not go into the new pack. This feature was broken because not all
commits have been checked whether they should be excluded or not. For
other object types the exclude algorithm worked. This commit adds the
missing check.

All commands should throw a GitAPIException so new exceptions can be
added without breaking the builds of old code, i.e. anyone that calls
a Git API should catch GitAPIException and not just the currently known
exceptions.
Now the only checked exceptions on Git API calls are GitException and
subclasses of it. New checked exceptions that are subclasses of
GitException may be added without breaking the API.
Javadoc for GitAPIException is declared on GitCommand and
inherited to subclasses. JGitInternalException is not explicitly
documented anymore.
Unfortunately this change itself breaks the API. The intention is
that it shall be possible to add new checked subclasses of
GitAPIException without breaking the API.

Previously if a packed-refs file was racily clean then there
was a 2.5 second window in which each call to getPackedRefs
would increment the mod count causing a RefsChangedEvent to be
fired since the FileSnapshot would report the file as modified.
If a RefsChangedListener called getRef/getRefs from the
onRefsChanged method then a StackOverflowError could occur
since the stack could be exhausted before the 2.5 second
window expired and the packed-refs file would no longer
report being modified.
Now a SHA-1 is computed of the packed-refs file and the
mod count is only incremented when the packed refs are
successfully set and the id of the new packed-refs file
does not match the id of the old packed-refs file.

If there are a lot of references to modify, using BatchRefUpdate can
save time if the underlying storage is able to combine these updates
together. This should speed up initial clone or fetch into an empty
repository, as some projects can have hundreds of release tags, or
hundreds of branch heads.

That happens when the index and a new file is created within the same

within the same second after adding it to the index. Without smudging

DirCacheCheckout and CanonicalTreeParser cooperate. CanonicalTreeParser
can detect malformed, potentially malicious tree entries and sets a
flag, while DirCacheCheckout refuses to work with such paths.
Malicious tree entries are ".", "..", ".git" (case insensitive), any
name containing '/' and (on Windows '\') and also (on Windows)
any paths ending in a combination of '.' or space or containing a ':'.
We also forbid all special names like "con" etc on Windows.
Some of the test can execute on any platform by enabling partial
platform emulation.
A new runtime exception, InvalidPathException, is introduced. For
backwards compatibility it extends InvalidArgumentException.

This extracts the logic for writing to the reflog from
RefDirectory into a new ReflogWriter class. This class
creates a public API for writing reflog entries similar
to ReflogReader for reading reflog entries.
The new command supports rewriting the stash's log to remove
a configured entry followed by updating the stash ref to
the value at the bottom of the newly written log.

Auto CRLF isn't special enough to be screwing around with the buffers

an ObjectInserter, it needs to do its own buffer management.

Previously a DirCacheCheckout was done using a merge tree reflecting
the state of the repository when the stash was originally done.
This was wrong since unstashing after making subsequent commits
would undo changes already committed by checking out entries from
an outdated tree.
The new approach is to scan for conflicts initially using a 6-way
tree walk that contains the trees for the stashed HEAD, stashed
index, stashed working directory, current HEAD, current index, and
current working directory. Then perform a subsequent scan of the
stashed HEAD, index, and working directory trees and apply all
the stashed differences to the current index and working directory.
