Previous code loaded the WorkingTreeOptions afresh for every single
file being checked out. This checked the git config (all three files,
repo, user and system config) for having been modified every time.
These checks can be costly, for instance on Windows, or if one of the
three config files is not on a local disk, or on an otherwise slow
storage.
Improve this by loading the options and thus checking the git config
only once before the checkout.

1. A TemporaryBuffer.LocalFile must be destroyed to ensure the

2. TemporaryBuffer.openInputStream() may be used only after
TemporaryBuffer.close().
3. The caller of DirCacheCheckout.getContent() is responsible for
closing the OutputStream!

With core.symlinks=false, symlinks are checked out as plain files.
When such a file is re-added to the index, and the index already
contains a symlink there, add the file as a symlink. Previous code
changed the index entry to a regular file.

We follow OSGi semantic versioning which allows breaking implementers in

Reapply "Create util class for work tree updating in both filesystem and index."
ResolveMerger: add coverage for inCore file => directory transition
I649db9ae679ec2606cf7c530b040f8b6b93eb81a added a default implementation
for getShallowCommits and setShallowCommits to DfsObjDatabase, for the
convenience of any implementers that define subclasses. But we forgot
that some implementers inherit from ObjectDatabase directly instead.
Move the default getter and setter to the base class so that such
callers do not need source changes to unbreak their build.
This also lets us update the api_filters to reflect that this is no
longer an API-breaking change.

This reverts commit 5709317f71.
Add a bugfix for deletions in ResolveMergers instantiated with just an
ObjectInserter as argument.
Original change description:
Create util class for work tree updating in both filesystem and index.
This class intends to make future support in index updating easier.
This class currently extracts some logic from ResolveMerger. Logic
related to StreamSupplier was copied from ApplyCommand, which will be
integrated in a following change.

This can allow passing a FilteredRevCommit which is the filtered list of
commit graph making it easier for Blame to work on. This can
significantly improve blame performance since blame can skip expensive
RevWalk.
Change-Id: I5dab25301d6aef7df6a0bc25a4c553c730199272
This makes RevCommit extensible to allow having different structure of
child-parent relationship. This change is a pre-requsite for having a
FilteredRevCommit that overrides parents from the RevCommit. That then
provides a cheaper way to walk over a subset of RevCommits instead of
an expensive way that applies filters while walking over selected
commits. Useful with Blame which works on a single file and that can be
made performant, if we know all the commits needed by the Blame
algorithm. So Blame algorithm can avoid walking over finding what
commits to blame on.
This change makes parents field on RevCommit private and exposes it
thrrough overrideable methods such as getParents, getParent at index,
getParentCount and setParents. All other files other than RevCommit are
updating the usages of accessing RevCommits parents.

Introduce named constants for packet line headers and use them instead
of direct string literals everywhere. This not only makes the code more
readable because we don't need NON-NLS markers, it also makes it more
robust since we can use the length of these constants instead of magic
numbers.

The NameConflictTreeWalk class is used in 3-way merge for iterating over
entries in 3 different commits. The class provides information about a
current entry and a state of the entry in commits (e.g entry is file,
entry is directory, entry is missing). In rare cases, the tree walker
can mix information about entries with different name.
The problem appears, because git uses unusual sorting order for
files. Example (this is a simplified real-life example):
Commit 1:
* gradle.properties - file
* gradle - directory (with nested files)
* gradle/file - file in gradle directory
Commit 2:
* gradle.properties - file
* no entry with the name gradle
Commit 3:
* gradle.properties - file
* gradle - file
Here the names are ordered like this:
"gradle" file <"gradle.properties" file < "gradle/file" file.
NameConflictTreeWalk iterator already have code for processing
git sorting order, however in the example above the code doesn't
work correctly. Before the fix, NameConflictTreeWalk returns:
#next()
"gradle - directory" | "gradle.properties" | "gradle - file" - which is
wrong. The expected result is
#next()
"gradle - directory | MISSED_FILE | "gradle - file"
#next()
"gradle.properties"|"gradle.properties"|"gradle.properties"
Ensure that the "matches" field of tree iterators (which contains the
current path) is kept in sync in the case above.

The RootIgnoreNode in a WorkingTreeIterator must _not_ add the rules
from .git/info/exclude or from the file designated by git config
core.excludesFile to the list of rules read from the root .gitignore.
These really must be separate nodes in a hierarchy, otherwise the
precedence rules from [1] are violated and the outcome is not the
same as in C git.

When using JGit on a non-bare repository, the CloneCommand
it previously created local reflogs for all branches including remote
tracking ones, causing the generation of a potentially large
number of files on the local filesystem.
The creation of the remote-tracking branches (refs/remotes/*) during
clone is not an issue for the local filesystem because all of them are
stored in a single packed-refs file. However, the creation of a large
number of ref logs on a local filesystem IS an issue because it
may not be tuned or initialised in term of inodes to contain a very
large number of files.
When a user (or a CI system) performs the CloneCommand against
a potentially large repository (e.g., millions of branches), it is
interested in working or validating a single branch or tag and is
unlikely to work with all the remote-tracking branches.
The eager creation of a reflogs for all the remote-tracking branches is
not just a performance issue but may also compromise the ability to
use JGit for cloning a large repository.
The behaviour implemented in this change is also consistent with the
optimisation done in the C code-base [1].
We differentiate between clone and fetch commands using --branch
<initialBranch> option, that is only available in clone command,
and is set as HEAD per default.

When JGit needs to serve a Git client requesting SHA1s
during the want phase, it needs to make a full reachability
check from the advertised refs to the ones requested to
keep all objects in the correct scope of confidentiality
allowed by the avertised refs.
The check is also performed when the SHA1 corresponds to
one of the tips of the advertised refs which is a waste of
resources.
Example:
fetch> ref-prefix refs/heads/foo
fetch< 900505eb8ce8ced2a1757906da1b25c357b9654e refs/heads/foo
fetch< 0000
fetch> command=fetch
fetch> 0001
fetch> thin-pack
fetch> ofs-delta
fetch> want 900505eb8ce8ced2a1757906da1b25c357b9654e
The SHA1 in the want is the tip of refs/heads/foo and therefore
the full reachability check can be shortened and resolved more
quickly.
