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).

Do not allow non-ff-rebase if there are uncommitted changes
With this change jgit checks for uncommitted changes before a rebase is
started. This is also done by native git. One reason is that an abort
would override such changes. The check is skipped for a non-interactive
rebase when it will result in a fast-forward. In this case there can be
only checkout conflicts but no merge conflicts, so there cannot be an
abort which overrides uncommitted changes.

Parse commitId and shortMessage of a commented out line in rebase todo
A rebase todo file consists of regular non-comment action lines and
comment lines. In case that a regular action line has been commented out
(i.e. prefixed with a hash '#'), the RebaseTodoLine that is representing
this line should hold the values for commitId and shortMessage even
though it's a comment line. This allows to switch between comment and
non-comment easily even after the file has been persisted and reread.

Enhance reading of git-rebase-todo formatted files
Reading and writing files formatted like the git-rebase-todo files was
hidden in the RebaseCommand. Certain constructs (like leading tabs and
spaces) have not been handled as in native git. Also the upcoming
rebase interactive feature in EGit needs reading/writing these files
independently from a RebaseCommand.
Therefore reading and writing those files has been moved to the
Repository class. RebaseCommand gets smaller because of that and doesn't
have to deal with reading/writing files.
Additional tests for empty todo-list files, or files containing comments
have been added.

In C Git 1.8.2, "git reset" now also works on an unborn branch (no HEAD

This can be useful for callers because "unborn branch" no longer has to

Handle short branch/tag name for setBranch in CloneCommand
Before, it was not clear from the documentation what kind of branch name
was accepted. Users specifying "branch" (instead of "refs/heads/branch")
got no error message and ended up with a repository without HEAD and no
checkout.
With this, CloneCommand now tries "$branch", then "refs/heads/$branch"
and then "refs/tags/$branch". C Git only does the last two, but for
compatibility we should still allow "refs/heads/branch".

There was a severe bug in CommitCommand which could corrupt
repos. When merging an annotated tag the JGit MergeCommand writes
correctly the ID of the tag (and not the id of the commit the tag was
pointing to) into MERGE_HEAD. Native git does the same. But
CommitCommand was reading this file and trusting blindly that it will
contain only IDs of commits. Then the CommitCommand created a
commit which has as parent a non-commit object (the tag object). That's
so corrupt that even native git gives up when you call "git log" in
such a repo.
To reproduce that with EGit simply right-click on a tag in the
Repository View and select Merge. The result was a corrupt repo!

Update tags on fetch if --tags or tag refspec specified
When either --tags or a tag ref is explicitly specified on fetch, C Git
updates existing local tags if they are different.
Before this change, JGit returned REJECTED in such a case. Now it
updates it and returns FORCED.
Example:
% mkdir a
% cd a
% git init -q
% touch test.txt
% git add test.txt
% git commit -q -m 'Initial'
% git tag v1
% cd ..
% git clone -q a b
% cd a
% echo Test > test.txt
% git commit -q -a -m 'Second'
% git tag -f v1
Updated tag 'v1' (was bc85c08)
% cd ../b
% git fetch --tags
- [tag update] v1 -> v1

Only fetch tags that do not exist locally with auto-follow
This corresponds to what C Git does, quoting from the fetch man page:
This is done by first fetching from the remote using the given
<refspec>s, and if the repository has objects that are pointed by
remote tags that it does not yet have, then fetch those missing tags.
Before, JGit would also fetch tags that exist locally but point to a
different object, resulting in REJECTED results for these.
Also add some test cases to cover more cases.

to each of the requested commits, keeping track of each path along which

single "best" path is chosen based on the total path length, with a
penalty applied for paths that traverse merges.
This functionality parallels "git name-rev".

CloneCommand has been creating fetch refspecs like this on bare clones:
[remote "origin"]
url = ssh://example.com/my-repo.git
fetch = +refs/heads/*:refs/heads//*
As you can see, the destination ref pattern has a superfluous slash.
It looks like this behaviour has always been the case for CloneCommand,
at least since cc2197ed when code catering to bare-clone fetch refspecs
was added. That was released with JGit v1.0 almost 2 years ago, so
there will probably be some bare repos in the wild which will have been
cloned with JGit and have these corrupted refspecs.
The effect of the corrupted fetch refspec is quite interesting. Up to
and including JGit 2.0, the corrupt refspec was tolerated and fetches
would work as intended with no indication to the user that anything was
amiss. With JGit 2.1, a change was introduced which made JGit less
tolerant, and fetches now attempt to update the non-existing ref
"refs/heads//master". No exception is raised, but the real ref -
"refs/heads/master" - is not updated.
This behaviour was noticed by a user of Agit (which does bare clones by
default and recently updated from JGit v2.0 to v2.2), reported here:
https://github.com/rtyley/agit/issues/92
If you run C-Git fetch on a bare-repo cloned by JGit, it flat-out
rejects the refspec (checked against v1.7.10.4):
fatal: Invalid refspec '+refs/heads/*:refs/heads//*'
Incidentally, C-Git does not create an explicit fetch refspec at all
when performing a bare clone - the full remote config generated by C-Git
looks like this:
[remote "origin"]
url = ssh://example.com/my-repo.git
Using JGit on such a repository works fine, so omitting the fetch
refspec entirely is also an option.
