JGit's ObjectDirectory implements the optimization that it remembers the
pack folders (.git/objects/pack) lastModified timestamp and doesn't
check for new packfiles in this folder if the lastModified attribute has
not changed.
In environments using NFS this can cause trouble. If multiple JGit
instances from multiple machines work on the same repository and one
instance creates a new ref and a new packfile (e.g. by doing a fetch)
then the other machines may detect the new ref but can't resolve the
referenced object because it doesn't detect that pack folder has a new
packfile. That's because NFS may cache file/folder metadata for quite a
long time and the pack folders modification time is not updated although
a new packfile is there and could be read.
The new config parameter core.trustfolderstat controls this behaviour.
The default is true and jgits behaviours is unchanged. But if this
parameter is set to false then jgit doesn't trust the pack directories
lastmodified anymore. Instead it will always iterate through the content
of that folder to detect new packfiles.

JGit style is to import exactly the classes required, and never
to use "import foo.*" as the foo package could add new classes
in the future which are conflicting/confusing with the imports
already used by a source file.

The latest changes to IndexDiff just assumed that all configured
submodules are allways cloned. If a configured submodule did not exist
an exception was thrown. This is fixed by this commit.

Inspired by the series[1], this implements the possibility to
have atomic ref transactions.
If the database supports atomic ref update capabilities, we'll
advertise these. If the client wishes to use this feature, either
all refs will be updated or none at all.

In a situation where a certain path was ignored but a working tree file
with this path existed jgit didn't allow to checkout a branch which
didn't ignore this path but contained different content. JGit considered
this to be a checkout conflict to prevent overwriting the file in the
working tree and raised an error. This commit fixes this by ensuring
that ignored dirty working tree files don't lead to a checkout conflict.

Before a rebase happens the RebaseCommand checks that the working tree
is clean. We don't want to start a rebase on a dirty working tree. If
the working tree is dirty a rebase should not be allowed. But
RebaseCommand should ignore modifications done to submodules. E.g. if a
submodules HEAD points to <x> but the root repository has in index that
the submodule should point to <y> then this should not prohibit a
rebase. Also native git allows a rebase in this case. Since jgit's
StatusCommand has learned to ignore submodule changes this is now used
by the RebaseCommand to determine the repository state correctly.

For each submodule native git allows to configure which modifications to
submodules should be ignored by the status command. It is possible to
ignore "none", "all", "dirty", "untracked" [1]. This configuration is
now supported by IndexDiff. The StatusCommand offers the possibility to
specify this mode.

The current IgnoreRule/FileNameMatcher implementation scales not well
with huge repositories - it is both slow and memory expensive while
parsing glob expressions (bug 440732). Addtitionally, the "double star"
pattern (/**/) is not understood by the old parser (bug 416348).
The proposed implementation is a complete clean room rewrite of the
gitignore parser, aiming to add missing double star pattern support and
improve the performance and memory consumption.
The glob expressions from .gitignore rules are converted to Java regular
expressions (java.util.regex.Pattern). java.util.regex.Pattern code can
evaluate expression from gitignore rules considerable faster (and with
less memory consumption) as the old FileNameMatcher implementation.

Applications sometimes use a RevFlag instead of a Set<RevObject>
to track boolean state bits about objects being processed. However
this requires careful use of the resetRetain() methods to avoid an
accidental clearing of the RevFlag bits, effectively clearing the
Set<RevObject> the application wanted to track.
Simplify that use case by offering retainOnReset, a collection of
flags that are never cleared by the RevWalk.

When during an ObjectWalk commits are marked as uninteresting we should
be tolerant against the situation that the commit exists in the repo but
the referenced tree is not exisiting. Since commit
c4797fe986 we are throwing
MissingObjectException in such a case. This semantic differs from native
git behaviour and may cause push operations to fail while they would
work in native git. See:

When writing new packs it should be allowed to specify objects as "have"
(objects which should not be included in the pack) which do not exist in
the local repository.
This works with the traditional PackWriter, but when PackWriter was
working on a repository with bitmap indexes and used
PackWriterBitmapWalker then this feature was broken. Non-existing "have"
objects lead to MissingObjectExceptions. That broke push and Gerrit
replication. When the replication target had branches unknown to the
replication source then the source repository wanted to build pack files
where "have" included branch-tips which were unknown in the source
repository.

JGit should offer the possibility to do a garbage collection in
"aggressive" mode. In this mode garbage collection more aggressively
optimize the repository at the expense of taking much more time.
Technically a aggressive mode garbage collection differs from a
non-aggressive one by:
- not reusing packed objects found in old packs. Recompress every object
- the configuration pack.window is set to 250 (the default is 10)
- the configuration pack.depths is set to 250 (the default is 50)
The associated classes in org.eclipse.jgit.api and the command line
command in org.eclipse.jgit.pgm expose this new option.
The configuration parameters gc.aggressiveDepth and gc.aggressiveWindow
have been introduced to configure this feature.
