Johannes Carlsson identified a race condition[1] that can lead to
spurious MissingObjectExceptions at read time. If two threads are
active inside of ObjectDirectory looking for a packed object and the
packList is currently the empty NO_PACKS list, thread A will find
no object and eventually consider tryAgain1(). If thread A is put
to sleep and this point and thread B also does not find the object,
loads the packs, when thread A wakes up its tryAgain1 would return
false and the thread never considers the packs.
Rework the internal API of ObjectDirectory to keep a handle on the
exact PackList that was iterated by thread A, allowing it to always
retry walking through the packs if the new PackList is different.
This had some ripple effect into the CachedObjectDirectory and
the shared FileObjectDatabase interface. The new code should be
slightly easier to follow, especially from the perspective of the
CachedObjectDirectory trying to minimize the number of open system
calls it makes to files matching "$GIT_DIR/objects/??/?x{38}".

In certain cases a JGit server updating an existing shallow client
selected a common ancestor that was behind the shallow edge of
the client. This allowed the server to assume the client had some
objects it did not have and allowed creation of pack deltas the
client could never inflate.
Any commit the client has advertised as shallow must be treated
by UploadPack server as though it has no parents. With no parents
the walker cannot visit graph history the client does not have,
and PackWriter cannot consider delta base candidates the client
is lacking.

When encountering a submodule entry, "jgit archive" tries to write its
content verbatim as an entry to the archive, which fails with a
JGitInternalException wrapping a MissingObjectException because the
submodule repository commits are typically not part of the
superproject.
When a subproject is available (for example because it has been
checked out as a subdirectory of a superproject worktree), it would be
nice to recurse into it and make one archive recording the state of
the entire project. Unfortunately sometimes the subproject is not
available or it can be hard to find (e.g., it can be on another
server). Even when some subprojects are available, "jgit archive"
should not produce different output for the same tree depending on
which subprojects it has easy access to, so there is no obvious good
default behavior that recurses without relying on access to all
subprojects.
Instead, replace each submodule entry with a placeholder empty
directory. "git archive" does the same.

Entries for directories are optional and mostly wasted space in most
archive formats (except as a place to hang ownership and filesystem
permissions), but "git archive" includes them. Follow suit.
This will make it easier in a later change to include empty
directories as placeholders for missing submodules.

This reverts commit 1def0a1257.
We found this fix uncovers problems with unsmudged DirCacheEntry's. This
surfaced because egit's ui test CreatePatchActionTest failed since jgit
computes a wrong status. JGit doesn't detect modified content in now
unsmudged entries. Hence revert this change until these problems are
fixed.

Common practice when distributing tarballs is to prefix all entries

This is the case for submodules in .git/modules, which typically have a

try to call Repository.stripWorkDir with it.

This came up while testing the proposed buck build for jgit. With buck
we can introduce smaller modules to allow for more concurrency during
build and to better control inner structure of jgit. Trying to put the
porcelain API into a different module than lower level implementation
classes failed since RebaseTodoLine used a porcelain API exception
causing a dependency cycle on the proposed modules. Using an exception
defined on the same abstraction level fixes this problem.

When there are conflicts with a recursive merge, the conflicting paths
are stored in unmergedPaths (field in ResolveMerger). Later, when the
MergeResult is constructed in MergeCommand, getBaseCommit is called,
which computes the merge base a second time.
In case of RecursiveMerger, getBaseCommit merges the multiple merge
bases into one. It does this not by creating a new ResolveMerger but
instead calling mergeTrees. The problem with mergeTrees is that at the
end, it checks if unmergedPaths is non-empty and returns false in that
case.
Because unmergedPaths was already non-empty because of the real merge,
it thinks that there were conflicts when computing the merge base again,
when there really were none.
This can be fixed by storing the base commit when computing it and then
returning that instead of computing it a second time.
Note that another possible fix would be to just use a new ResolveMerger
for merging the merge bases instead. This would also remove the need to
remember the old value of dircache, inCore and workingTreeIterator (see
RecursiveMerger#getBaseCommit).
