The 'factory' field is lazy initialized in the detect() method.
According to FindBugs:
Because the compiler or processor may reorder instructions, threads
are not guaranteed to see a completely initialized object, if the
method can be called by multiple threads.
Fix this by declaring the member as 'volatile'.

Earlier we tried to close the repository before removing it from the
cache, so close only reduced refcount but didn't close it.
Now that we no longer leak usage count on purpose and the usage count is
now ignored anyway, there is no longer a need to run the removal twice.

Symlinks on MacOS are written as UTF-8 NFD, but
readSymbolicLink().toString() converts to NFC with potentially fewer
bytes. May occur in particular if the link target has non-ASCII
characters for which the NFC and NFD encodings differ. This may lead
to an EOFException: Short read of block.
This causes all kinds of weird effects in EGit, ranging from failing
rebases (which report the exception to the user) to EGit decorations in
the navigator silently disappearing (and never coming back).
* Rename readContentAsNormalizedString() to readSymlinkTarget() as it's
called only for symlinks. Also make it protected.
* Fix by allowing the read to succeed even if less than the expected
number of bytes are returned by the entry's input stream.
* Override in FileTreeIterator to use fs.readSymlink() directly.
Includes a new MacOS-only test.

CheckoutCommand was not returning updated and removed files in case of
an overall status of NONDELETED. That's status which occurs especially
on the Windows platform when Checkout wanted to delete files but the
filesystem doesn't allow this. The situation is more seldom on linux/mac
because open filehandles don't stop a deletion attempt and checkout
succeeds more often.

There was a bug when carrying over flags from a merge commit to its
non-first parents. The first parent of a merge commit was handled
differently and correct but the non-first parents are handled by a
recursive algorithm. Flags should be copied from the root merge commit
to parent-2, to grandparent-2, ... up to the limit of STACK_DEPTH==500
parents-levels. But the recursive algorithm was always copying only to
the direct parents of the merge commit and not the grand*-parents.
This seems to be no problem when commits are handled in a strict date
order because then copying only one level is no problem if children are
handled before parents. But when commits are not seperated anymore by
distinctive correct dates (e.g. because all commits have the same date)
then it may happen that a merge-parent is handled before the merge
commit and when dealing later with the merge commit one has to copy
flags down to more than one level

If the configuration parameter filter.<filterDriverName>.useJGitBuiltin
is set to true then for all corresponding filters JGit will try to
execute the built-in filter instead of the filter-command which is
defined in git configuration. It will fallback to the non-built-in
filters if no built-in filters are registered or if constructing them
leads to exceptions. If set to false JGit will not try to execute
built-in filters for the specified filter driver.
Example: The configuration contains the following lines
[filter "lfs"]
clean = git-lfs clean -- %f
smudge = git-lfs smudge -- %f
useJGitBuiltin = true
Addtionally the .gitattributes file in the root of the working tree
contains:
*.bin filter=lfs
In this case when new content is added similar to "git add 1.bin" then
the following will happen:
- jgit will check whether a built-in command factory was registered
for the command "jgit://builtin/lfs/clean". If that is true the
factory is used to create a built-in filter command and that
command is used to filter the content
- Otherwise jgit will call the external program "git lfs clean ..."
to do the filtering

JGit supports smudge filters defined in repository configuration. The
filters are implemented as external programs filtering content by
accepting the original content (as seen in git's object database) on
stdin and which emit the filtered content on stdout. This content is
then written to the file in the working tree. To run such a filter JGit
has to start an external process and pump data into/from this process.
This commit adds support for built-in smudge filters which are
implemented in Java and which are executed by jgit's main thread. When a
filter is defined in the configuration as
"jgit://builtin/<filterDriverName>/smudge" then JGit will lookup in a
static map whether a builtin filter is registered under this name. If
found such a filter is called to do the filtering.
The functionality in this commit requires that a program using JGit
explicitly calls the JGit API to register built-in implementations for
specific smudge filters. In follow-up commits configuration parameters
will be added which trigger such registrations.

DfsRefDatabase#compareAndPut had a vague semantics for reference
matching. Because of this, an operation to make a symbolic
reference had been broken for some DFS implementations even if they
followed the contract of compareAndPut. The clarified semantics
requires the implementations to satisfy the followings:
* Matching references should be both symbolic references or both
object ID references.
* If both are symbolic references, both should have the same target
name.
* If both are object ID references, both should have the same object
ID.
This semantics is defined based on
https://git.eclipse.org/r/#/c/77416/. Before this commit,
DfsRefDatabase couldn't see the target of symbolic references.
InMemoryRepository is changed to comply with the new semantics. This
semantics change can affect the existing DFS implementations that only
checks object IDs. This commit adds two tests that the previous
InMemoryRepository couldn't pass.

When doing a detaching operation, JGit fakes a SymbolicRef as an
ObjectIdRef. This is because RefUpdate#updateImpl dereferences the
SymbolicRef when updating it. For example, assume that HEAD is
pointing to refs/heads/master. If I try to make a detached HEAD
pointing to a commit c0ffee, RefUpdate dereferences HEAD as
refs/heads/master first and changes refs/heads/master to c0ffee. The
detach argument of RefDatabase#newUpdate avoids this dereference by
faking HEAD as ObjectIdRef.
This faking is problematic for the linking operation of
DfsRefDatabase. It does a compare-and-swap operation on every
reference change because of its distributed systems nature. If a
SymbolicRef is faked as an ObjectRef, it thinks that there is a
racing change in the reference and rejects the update. Because of
this, DFS based repositories cannot change the link target of symbolic
refs. This has not been a problem for file-based repositories because
they have a file-lock based semantics instead of the CAS based one.
The reference implementation, InMemoryRepository, is not affected
because it only compares ObjectIds.
When [1] introduced this faking code, there was no way for RefUpdate
to distinguish the detaching operation. When [2] fixed the detaching
operation, it introduced a detachingSymbolicRef flag. This commit uses
this flag to control whether it needs to dereference the symbolic refs
by calling Ref#getLeaf. The same flag is used in the reflog update
operation.
This commit does not affect any operation that succeeds currently. In
some DFS repository implementations, this fixes a ref linking
operation, which is currently failing.

2. mvn package
3. org.eclipse.jgit.pgm/target/jgit \

OpenJDK replaces the underlying OutputStream with NullOutputStream when
the process exits. This throws IOException for all write operation. When
it exits before JGit writes the input to the pipe buffer, the input
stays in BufferedOutputStream. The close method tries to write it again,
and IOException is thrown.
Since we ignore IOException in StreamGobbler, we also ignore it when
we close the stream.
