resolve("foo~X") where X is greater than the distance from foo to the

Also add an analogous test for foo^X where X is greater than the

The underlying problem is that System.out is a PrintWriter and
as such it does not throw exceptions on error, but rather just
sets a flag and continues.
This changes replaces the use of System.out with a PrintWriter-like

ResolveMerger throws a MissingObjectException when it encounters
a submodule conflict while merging. The reason is that it treats
the submodule link as a blob and tries to read its contents.
We solve the issue by detecting before content merge whether the
path to be merged is a submodule link, and skip the content
merge if it is.

None of these should have been exposed to base classes. The majority
of them are private implementation details that are not required by a
subclass in order to interact with the base protocol definition. The
few that are needed should be visible as accessor methods, so the
internals can be modified without breaking the public JGit API.

This flag was added to provide an unsafe operation on the local

proper safe Git behavior all of the time. Now that stoarge.dht has
been removed from the repository, also delete this unsafe flag to
prevent applications from misusing the JGit library and permitting
users to potentially damage their local repository with bad data

When a file is not in the index and neither contents nor mode differ
between "head" and "merge", the index state should be kept. If they
differ, a checkout conflict should occur. This is described in Git's
git-read-tree.txt.
JGit used to replace the index state with "merge" in both of the above
cases.
A confusing effect of this was that when one removed a file and then did
a rebase, the file silently reappeared again.
The changes to dir/file conflict handling are a consequence of this
change, as the index handling change made tests in DirCacheCheckoutTest
break. I compared these cases to C Git and the new behavior there also
matches what C Git does.

In order to parse user specified strings containing date and time info
a thread-safe parser is implemented. This is needed for example to
interpret configuration parameters (e.g. gc.pruneexpire where need to
parse strings like "2 weeks ago"). The parser is thread-safe by caching
SimpleDateFormat instances in a ThreadLocal cache.
Native git has a parser called approxidate which is able to interpret a
huge number of formats ("1 year ago", "tea time", ...). Ideally JGit
should be able to parse the same strings as native git but for now this
parser understands the following subset:
"now"
"yesterday"
"(x) years|months|weeks|days|hours|minutes|seconds ago"
"yyyy-MM-dd HH:mm:ss Z" (ISO)
"EEE, dd MMM yyyy HH:mm:ss Z" (RFC)
"yyyy-MM-dd"
"yyyy.MM.dd"
"MM/dd/yyyy"
"dd.MM.yyyy"
"EEE MMM dd HH:mm:ss yyyy Z" (DEFAULT)
"EEE MMM dd HH:mm:ss yyyy" (LOCAL)

JGit was not able to lookup refs which had the name of files which exist
in the .git folder. When JGit was looking up a ref named X it has a
fixed set of directories where it searched for files named X
(ignore packed refs for now). First directory to search for is .git. In
case of the ref named 'config' it searched there for this file, found it
(it's the .git/config file with the repo configuration in it), parsed
it, found it is an invalid ref and stopped searching. It never looked
for a file .git/refs/heads/config.
I changed JGit in a way that when it finds a file in GIT_DIR which
corresponds to a ref name and if this file doesn't contain a valid ref
then it will ignore the InvalidObjectIdException and continue searching.

On conflicts in rebase or cherry-pick, the conflict markers were like
this:
<<<<<<< OURS
a
=======
b
>>>>>>> THEIRS
This is technically correct, but it could be better.
It's especially confusing during a rebase, where the meaning of
OURS/THEIRS is not obvious. The intuition is that "ours" is the commits
that "I" did before the rebase, but it's the other way around because of
the way rebase works. See various bug reports and stackoverflow
discussions.
With this change, in the case of a cherry-pick while on master, the
markers will be like this:
<<<<<<< master
a
=======
b
>>>>>>> bad1dea Message of the commit I'm cherry-picking
In the case of a "git rebase master":
<<<<<<< Upstream, based on master
a
=======
b
>>>>>>> b161dea Message of a commit I'm rebasing
It's not "master" because that would only be correct for the first
cherry-pick during a rebase, after that, it's master + already
cherry-picked commits.
And in the case of a "git pull --rebase":
<<<<<<< Upstream, based on branch 'master' of git@example.org:repo
a
=======
b
>>>>>>> b161dea Message of a commit I'm rebasing

JGit allows to create commits which have duplicate parents: e.g. a
commit X has first parent Y and second parent Y. Such commits are not
handled correctly by PlotCommit leading to wrong display of the history
in EGit. In such cases there is a never ending passing line drawn beside
all commits younger than the commit with duplicate parents. This commit
fixes this by explicitly checking for duplicate parents.
In a different commit we should fix JGit not to create commits with
duplicate parents. I think native git also doesn't allow such commits,
although history display in native git (gitk, git log --graph) is not
damaged by such commits.

Implements a garbage collector for FileRepositories. Main ideas are
copied from the garbage collector for DFS based repos
(DfsGarbageCollector). Added functionalities are
- pruning loose objects
- handling of the index
- packing refs
- handling of reflogs (objects referenced from reflog will not be
pruned/)
These are features of a GC which are not handled in this change and
which should come with subsequent changes:
- unpacking packed objects into loose objects (to support that pruning
packed objects doesn't delete them until they are older than two weeks)
- expiration of reflogs
- support for configuration parameters (e.g. gc.pruneExpire)

Currently, after a merge/cherry-pick/rebase, all index entries are
smudged as the ResolveMerger never sets entry lengths and/or
modification times. This change teaches it to re-set them at least for
things it did not touch. The other entries are then repaired when the
index is persisted, or entries are checked out.
The first attempt to get this in was commit
3ea694c252 which has been reverted.
Since then some fixes to ResolveMerger and a few more tests have
been added which check situations where the index is not matching
HEAD before we merge.

Repository.resolve can only return an ObjectId and will
continue to do so, but another method, simplify(), will
be able to return a branch name for some cases.
Previous checkouts can be specified as @{-n}, where n is an
integer speifying the n:th previous branch. The result
is the branch name, unless the checkout was a detached head,
in which case the object id is returned. Since the result
is a branch it may be followed by a references to the reflog,
such as @{-1}@{1} if necessary.
A simple expression like "master" is resolved to master in
simplify, but anything starting with refs gets resolved to
its object id, even if it is a branch.
A symbolic ref is resolved to its leaf ref, e.g. "HEAD" might
be resolved to "master".
