Previously, we called destroy() to delete the temp file on failure only
when catching an IOException, not a RuntimeException. Use a slightly
different construction with a finally block to ensure it's always
deleted on error (assuming the JVM is still healthy enough).

With native git, .git/rebase-merge/rewritten exists actually in two
different cases:
* as a file in git rebase --merge recording OIDs for copying notes
* as a directory in git rebase --preserve-merges
Add a comment, and check for isDirectory() instead of exists().

ONTO_NAME must be "onto_name", not "onto-name".
For native git, --preserve-merges is an interactive mode. Create the
INTERACTIVE marker file, otherwise a native git rebase --continue
will fall back into rebase --merge mode before git 2.19.0 since it
started looking for the REWRITTEN directory to make the distinction
only then.[1]
This allows a JGit interactive rebase to be continued via native git
rebase --continue.

Aborting a rebase used ORIG_HEAD to reset. Strictly speaking this is
not correct, since other commands run during the rebase (for instance,
when the rebase stopped on a conflict) might have changed ORIG_HEAD.
Prefer the OID recorded in the orig-head file, falling back to the
older "head" file if "orig-head" doesn't exist, and use ORIG_HEAD only
if neither exists.

With text=auto or core.autocrlf=true, git does not normalize upon
check-in if the file in the index contains already CR/LFs. The
documentation says: "When text is set to "auto", the path is
marked for automatic end-of-line conversion. If Git decides that
the content is text, its line endings are converted to LF on
checkin. When the file has been committed with CRLF, no conversion
is done."[1]
Implement the last bit as in canonical git: check the blob in the
index for CR/LFs. For very large files, we check only the first 8000
bytes, like RawText.isBinary() and AutoLFInputStream do.
In Auto(CR)LFInputStream, ensure that the buffer is filled as much as
possible for the isBinary() check.
Regarding these content checks, there are a number of inconsistencies:
* Canonical git considers files containing lone CRs as binary.
* RawText checks the first 8000 bytes.
* Auto(CR)LFInputStream checks the first 8096 (not 8192!) bytes.
None of these are changed with this commit. It appears that canonical
git will check the whole blob, not just the first 8k bytes. Also
note: the check for CR/LF text won't work with LFS (neither in JGit
nor in git) since the blob data is not run through the smudge filter.
C.f. [2].
Two tests in AddCommandTest actually tested that normalization was
done even if the file was already committed with CR/LF.These tests
had to be adapted. I find the git documentation unclear about the
case where core.autocrlf=input, but from [3] it looks as if this
non-normalization also applies in this case.
Add new tests in CommitCommandTest testing this for the case where
the index entry is for a merge conflict. In this case, canonical git
uses the "ours" version.[4] Do the same.

Since 2011-02-10 (i.e., git 1.7.6)[1] native git uses "orig-head" for
REBASE_HEAD. JGit was still using "head". Currently native git has a
legacy fall-back for reading this, but for how long? Let's write to
both. Note that JGit never reads this file.

Android for instance forbids hard linking via a SELinux
policy. If we can't hard link, the NFS work-around for
atomic file creation cannot work at all. In this case,
fall back to not using the hard-linking mechanism.
Android throws an AccessDeniedException, so we catch that.
The javadoc on Files.createLink() indicates that another
possibility might be a SecurityException, so catch that,
too.

inspecting the folder using the finder application. This led to a

to ensure the method only tries to iterate contained folders but not

Several problems:
* The command didn't specify whether it expected short or full names.
* For the new name, it expected a short name, but then got confused
if tags or both local and remote branches with the same name existed.
* For the old name, it accepted either a short or a full name, but
again got confused if a short name was given and a tag with the
same name existed.
With such an interface, one cannot use Repository.findRef() to
reliably find the branch to rename. Use exactRef() for the new
name as by the time the Ref is needed its full name is known.
For determining the old Ref from the name, do the resolution
explicitly: first try exactRef (assuming the old name is a full
name); if that doesn't find anything, try "refs/heads/<old>" and
"refs/remotes/<old>" explicitly. Throw an exception if the name
is ambiguous, or if exactRef returned something that is not a
branch (refs/tags/... or also refs/notes/...).
Document in the javadoc what kind of names are valid, and add tests.
A user can still shoot himself in the foot if he chooses exceptionally
stupid branch names. For instance, it is still possible to rename a
branch to "refs/heads/foo" (full name "refs/heads/refs/heads/foo"),
but it cannot be renamed further using the new short name if a branch
with the full name "refs/heads/foo" exists. Similar edge cases exist
for other dumb branch names, like a branch with the short name
"refs/tags/foo". Renaming using the full name is always possible.

As explained in 'The "Double-Checked Locking is Broken"
Declaration'[*], Java's memory model does not support double-checked
locking:
class LazyReadableChannel {
private ReachableChannel rc = null;
public ReadableChannel get() {
if (rc == null) {
synchronized (this) {
if (rc == null) {
rc = new ReadableChannel();
}
}
}
return rc;
}
}
With JDK 5 and newer, there is a formal memory model that ensures this
works if "rc" is volatile, but it is still not thread-safe without
that.
Fortunately, this ReadableChannelSupplier is never passed between
threads, so it does not need to be thread-safe. Simplify by removing
the synchronization.
