The fix is to move the new head commit to the newly-created revert
commit, so that additional revert commits will use the correct head.

Apparently repo allows projects overlapping, e.g. one project's path is "foo"
and another project's path is "foo/bar". This is not supported in git submodule.
At JGit repo side we'll skip all the submodules that are in subdirectories of
other submodules, and on repo side we'll make them submodules to resolve this
problem.

Previously when RecursiveMerger was trying to create a single virtual
common base for the merge it was failing when this lead to content-merge
conflicts. This is different from what native git is doing. When native
git's recursive merge algorithm creates a new common base it will merge
the multiple parents and simply take the merge result (potentially
including conflict markers) as common base. See my discussion with Shawn
here: http://www.spinics.net/lists/git/msg234959.html :
> - How should workingtree, index (stage1,2,3) look like if during
that
> merge of common ancestors a conflict occurs? Will I see in stage2
and

Its done entirely in memory and never touches the working tree or
index. When a conflict exists in the X1-X2 merge the conflict is
preserved into the new virtual base.
There is still the possibility that the merge of parents lead to
conflicts. File/Folder conclicts, conflicts on filemodes. This commit
only fixes the situation for conflicts when merging content.

During recursive merge jgit potentially has to merge multiple
common ancestors. If this fails because there are conflicts then
the exception thrown for that should have a message which states
this clearly. Previously a wrong message was given ("More than 200
merge bases ...")

Each time the longest common substring is found the diff algorithm
recurses to reprocess the regions before and after the common string.
Large files with many edits can trigger StackOverflowError as the
algorithm attempts to process a deeply split tree of regions. This
is especially prone to happen in servers where the Java stack size
may have been limited to 1M or even 256K.
To keep edits produced in order a queue is used to process edits
in a depth-first strategy.

When RecursiveMerger tried to determine a common base tree it was
recursively tried to merge multiple common bases. But these intermediate
merges which have just been done to determine a single common base for
the final merge already filled some important fields (toBeCheckedOut,
toBeDeleted, ...). These side effects of the intermediate merges led to
wrong results of the final merge. One symptom was that after a recursive
merge which should be succesful you could still see leftover files in
the worktree: files which existed in the (virtual) common base but which
don't exist anymore in the branches to be merged.
The solution is easy: Clear the appropriate fields after common base
determination and start the final merge with a clean state.

As described in native gits file "git-read-tree.txt" git has in a
special mode when doing the "initial" checkout. "Initial" means that the
index is empty before the checkout. This was not handled correctly in
JGit and is fixed in this commit. Also see

Setting branch.<name>.rebase or pull.rebase to 'preserve' will preserve
merges during rebase. Also, pull.rebase is now consulted if there is no
branch-specific configuration.

With --preserve-merges C Git re-does merges using the rewritten merge
parents, discarding the old merge commit. For the common use-case of
pull with rebase this is unfortunate, as it loses the merge conflict
resolution (and other fixes in the merge), which may have taken quite
some time to get right in the first place.
To overcome this we use a two-fold approach:
If any of the (non-first) merge parents of a merge were rewritten, we
also redo the merge, to include the (potential) new changes in those
commits.
If only the first parent was rewritten, i.e. we are merging a branch
that is otherwise unaffected by the rebase, we instead cherry-pick the
merge commit at hand. This is done with the --mainline 1 and --no-commit
options to apply the changes introduced by the merge. Then we set up an
appropriate MERGE_HEAD and commit the result, thus effectively forging a
merge.
Apart from the approach taken to rebase merge commits, this
implementation closely follows C Git. As a result, both Git
implementations can continue rebases of each other.
Preserving merges works for both interactive and non-interactive rebase,
but as in C Git it is easy do get undesired outcomes with interactive
rebase.
CommitCommand supports committing merges during rebase now.

Connecting to an SshSession may fail due to different reasons. Jsch for
example often throws an com.jcraft.jsch.JschException: verify: false.[1]
The issue is still not fixed in JSch 0.1.51.
In such a case it is worth retrying to connect. The number of connection
attempts can be configured using ssh_config parameter
"ConnectionAttempts" [2].
Don't retry if the user canceled authentication.

The current behavior of passing a TreeFilter to RevWalk has limited
usefulness, since the RevFilter derived from the TreeFilter is always
ANDed together with any other RevFilters. It is also tied fairly
tightly to the parent rewriting mechanism.
Make TreeRevFilter a generic RevFilter that matches modified paths
against any TreeFilter. This allows for more complex logic like
(modified this path OR authored by this person).
Leave the rewrite flag logic in this class, since it's closely tied to
the parent comparison code, but hidden behind a protected constructor.

Originally, blame's walk to find a scapegoat to blame for a file
walking backward from a commit used the test
treeWalk.getFileMode(0).getObjectType() != OBJ_BLOB
to throw out gitlink (submodule) entries. Later, 52500d3264 (blame:
Micro optimize blob lookup in tree, 2014-04-17) changed that test to
(treeWalk.getRawMode(0) & TYPE_FILE) != TYPE_FILE
These checks are not the same, though: the older test accepts files
and symlinks, while the newer one accepts files, symlinks, and gitlink
(submodule) entries. This is particularly broken in the submodule
case --- trying to parse the referred-to commit as a blob produces
caught an exception: GET /gerrit/+blame/master/plugins/reviewnotes HTTP/1.1
org.eclipse.jgit.errors.MissingObjectException: Missing blob 61702414c046dd6b811c9137b765f9db422f83db
Stick to just (possibly executable) files instead. Symlinks are not
line-oriented data so blame on a symlink is not likely to be useful.
A quick grep for '& TYPE_' doesn't find any other instances of this
bug.

TranslationBundle#load() used to load resource bundles through
ResourceBundle#getBundle() without explicitly specifying a class loader.
In this case, the class laoder of the calling class (TranslationBundle
here) is used. This approach fails in runtime environments like OSGi
where there are multiple class loaders.
This change enables loading resource bundles in multi class loaders
environments. The fix is to pass the class loader of the
TranslationBundle-derived class to ResourceBundle#getBundle().

case of digest and basic authentication type names to all uppercase.
This broke digest authentication at least when using Gerrit as the git
server.
According to RFC2617 [1] "Basic" and "Digest" is the literal to be used
in authentication headers and not "BASIC" [1] and "DIGEST" [2].
According to RFC4559 "Negotiate" [3] is used for SPNEGO based
authentication.
