If multiple threads attempted to insert loose objects into the same new
fan-out directory, the creation of that directory was subject to a race
condition that could lead to an unnecessary IOException being thrown -
because an inserter could not 'create' a directory that had just been
generated by a different thread. All we require is that the directory
does indeed *exist*, so not being able to _create_ it is not actually a
fatal problem. Setting 'skipExisting' to 'true' on the call to mkdir()
fixes the issue.
I found this issue as a real world occurrence while working on The BFG
Repo Cleaner (https://github.com/rtyley/bfg-repo-cleaner), a tool which
concurrently performs a lot of object creation.
In order to demonstrate the problem here I've added a small test case
which reliably reproduces the issue on the few different hardware
systems I've tried. The error thrown when the race-condition arises is
this:
java.io.IOException: Creating directory /home/roberto/repo.git/objects/e6 failed

This converts a checkout conflict exception into a RebaseResult /
MergeResult containing the conflicting paths, which enables EGit (or
others) to handle the situation in a user-friendly way

This is necessary because some versions of JGit containing
the flawed c98abc9c05 were
used in the wild and wrote bad configuration files. We now
must accept this value in addition to the preferred case.

Previously, the FileObjDatabase required both the pack file path and
index file path to be passed to openPack(). A future change to add
a bitmap index will add a .bitmap file parallel to the pack file
(similar to the .idx file). Update the PackFile to support
automatically loading pack index extensions based on the pack file
path.

Previously, the DfsObjDatabase had a hardcoded getPackFile() and
getPackIndex() methods which opens a .pack and .idx file, respectively.
A future change to add a bitmap index will need to be stored in a
parallel .bitmap file. Update the DfsObjDatabase to support opening and
writing of files for any pack extension.

Once we start talking about parents of tags, we are in the commit
graph, so treat all objects from this point as commits. This fixes
spurious IncorrectObjectTypeExceptions on resolving expressions like
tag^^.

It stopped working when we moved to the Eclipse foundation's Gerrit
server since it doesn't use the Gerrit internal user store but LDAP.
Instead, since 2.0, we use the Eclipse foundation's automatic IP log
generator [1] to generate IP logs for releasing jgit and egit.

FastForwardMode should be represented by different enums depending on
context it is set or get from. E.g. FastForwardMode.FF_ONLY for
branch.<name>.mergeoptions is "--ff-only" but for merge.ff it is "only".

This requires that we internally sort all paths so content of
directories follow the directory immediately.

When piping output to another program, the other pipe may exit
before we are done. An example is "jgit log|head". The result is
that errno get set to EPIPE. Unfortunately Java does not have
specific exception for this so we have to look at the exception
message and hope that the number of variants are small.
The detection here seem to work on Windows, Linux and OS X and it
seems the message is usually not localized.

The org.eclipse.jgit.orbit.feature introduced recently in order to
install 3rd party Orbit dependencies is a too coarse grained approach
and has the effect to install some dependencies only needed for
org.eclipse.jgit.pgm when installing org.eclipse.jgit.feature.
Hence include the required 3rd party bundles into the respective jgit
features directly in order to avoid this problem.

This logic is similar to what we do on Windows, but in this case it's
Java that truncates the timestamps, not Git.

This reverts commit 75eb6a147f.
Applications that want a PathFilter to abort the walk early should be
using PathFilterGroup. When a PathFilterGroup is created with exactly
one path its implementation is the same that 75eb6 tried to perform,
but has been long documented as having the behavior of breaking a
higher level OR filter graph node.

Cherry-pick has been fixed, but even though revert does
basically the same thing, the fixes were not carried over here.
- Recognize the revert-states, analogous to the cherry picking states
- Make reset handle a revert-in-progress
- Update REVERT_HEAD and MERGE_MSG when revert fails due to conflicts
- Clear revert state on commit and reset
- Format the message similarily to how cherry-pick does. This is
not exactly how C Git does it.
The interface is still not the same as for cherry-picking.

After the current path of the TreeWalk is no longer a prefix of the
PathFilter's path, there can be no more matching entries, but TreeWalk
will happily keep walking the rest of a (potentially very large and
recursive) tree unless StopWalkException is thrown. So, throw
StopWalkException from PathFilter.include() at the earliest
opportunity.

The maxMemory for a DeltaWindow can be optionally disabled when it is
less than or equal to zero. Respect this configuration when enforcing
the limits on object load.
Change-Id: Ic0f4ffcabf82105f8e690bd0eb5e6be485a313b3
Previously, memory limits were enforced at the start of each iteration
of the delta search, based on objects that were currently loaded in
memory. However, new objects added to the window may be expanded in a
future iteration of the search and thus were not accounted for correctly
at the start of the search. To fix this, memory limits are now enforced
before each object is loaded.

there is a deprecation warning at about every line, which is not helpful.

A few classes such as Constanrs are marked with @SuppressWarnings, as are
toString() methods with many liternal, but otherwise $NLS-n$ is used for
string containing text that should not be translated. A few literals may
fall into the gray zone, but mostly I've tried to only tag the obvious
ones.

Add a new feature for the 3rd party dependencies jgit needs and include
this in org.eclipse.jgit.feature. This ensures that the jgit p2
repository is self-contained and downstream consumers don't need to find
the dependencies elsewhere. We don't add the jetty dependencies needed
to install the test feature org.eclipse.jgit.junit since this is only
used by egit tests.

reset() was broken and probably only worked when the position was
at the beginning. More serious was that back() sometimes descended
into the tree rather than skipping backward at the same level. Sometimes
this would result in false conflicts, but one could suspect silent
errors too. back() is called by the NamingConflictTreeWalk when looking
for directory/file conflicts.
Also added toString to DirCacheTree to simplify debugging.
