Fix CheckoutCommand to return updated files even on NONDELETED status
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

Unconditionally close repository in unregisterAndCloseRepository
Repository.close() method is used when reference counting and expiration
needs to be honored. The RepositoryCache.unregisterAndCloseRepository
method should close the repository unconditionally. This is also indicated
from its javadoc.
The class AtomicObjectOutputStream should be available to all lfs
related classes, not only to the server side. Move the class from
org.eclipse.jgit.lfs.server.fs to org.eclipse.jgit.lfs.internal to
achieve that.
Adds a JGit built-in implementation of the "git lfs smudge" filter. This
filter should do the same as the one described in [1] besides that it
only supports the local case when the lfs objects are already present in
the media directory. Remote cases where download of LFS objects from an
LFS server is needed will be done in a later commit.
Adds a JGit built-in implementation of the "git lfs clean" filter. This
filter should do the same as the one described in [1]. But since this
filter is written in Java and can be called by JGit without forking new
processes it should be much faster
Add configuration parameter to enable built-in hooks/filters
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
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.
JGit supports clean filters defined in repository configuration. The

Clarify the semantics of DfsRefDatabase#compareAndPut
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.

Shallow fetch/clone: Make --depth mean the total history depth

depth=0 still means a non-shallow clone. depth=1 now means only the

This is accomplished by changing the semantic meaning of "depth" in
UploadPack and PackWriter to mean the total depth of history desired,
while keeping "depth" in DepthWalk.{RevWalk,ObjectWalk} to mean
the depth of traversal. Thus UploadPack and PackWriter always
initialize their DepthWalks with "depth-1".
