Eclipse has some problem re-running single JUnit tests if
the tests are in Junit 3 format, but the JUnit 4 launcher
is used. This was quite unnecessary and the move was not
completed. We still have no JUnit4 test.
This completes the extermination of JUnit3. Most of the
work was global searce/replace using regular expression,
followed by numerous invocarions of quick-fix and organize
imports and verification that we had the same number of
tests before and after.
- Annotations were introduced.
- All references to JUnit3 classes removed
- Half-good replacement for getting the test name. This was
needed to make the TestRngs work. The initialization of
TestRngs was also made lazily since we can not longer find
out the test name in runtime in the @Before methods.
- Renamed test classes to end with Test, with the exception
of TestTranslateBundle, which fails from Maven
- Moved JGitTestUtil to the junit support bundle

If the 'TREE' extension contains an invalid subtree that has
been removed, DirCacheIterator still tried to access it due to
an invalid childCnt field within the parent DirCacheTree object.
This is easy for a user to do, they just need to move all files
out of a subdirectory.
For example, the input for the JUnit test case for this bug was
built using the following C Git sequence:
mkdir -p a/b
touch a/b/c q
git add a/b/c q
git write-tree
git mv a/b/c a/a
After the last step, the subdirectory a/b is empty, as its only
file was moved into the parent directory. Because of the earlier
`git write-tree` operation, there is a 'TREE' extension present, but
the a and a/b subdirectories have been marked invalid by the rename.
When JGit tried to iterate over the a tree, it tried to correct
childCnt to be zero as a/b no longer exists, but it failed to
update childCnt.

Each time getConfig() is called on FileRepository, it checks the
last modified time of both ~/.gitconfig and $GIT_DIR?config. If
$GIT_DIR/config appears to have been modified, it is read back in
from disk and the current config is wiped out.
When mutating a configuration file, this may cause in-memory edits
to disappear. To avoid that callers need to avoid calling getConfig
until after the configuration has been saved to disk.
Unfortunately the API is still horribly broken. Configuration should
be modified only while a lock is held on the configuration file, very
similar to the way a ref is updated via its locking protocol. But our
existing API is really broken for that so we'll have to defer cleaning
up the edit path for a future change.

Always use streaming (for SHA-checksum & collision detection)
when indexing whole blobs, regardless of their size.
Positives:
* benefits of bugfix #312868 will apply to all runtimes, without
additional conf for mem-constrained JVMs (5MB huge for some)
* no byte array allocation
(re-uses readBuffer instead of allocating new full-size array)
* mildly better overall performance
(given the usual blob-does-not-need-collision-checking case)
* removes unnecessary code
Negative:
* doubles the disk IO for a blob comparision
(comparitively rare occurance)
I perf-tested a range of threshold sizes against a random selection
of packfiles I found on my harddrive, the results are here:
https://spreadsheets.google.com/ccc?key=tLCQElyyd2RKN9QevfvgwGQ&hl=en_GB#gid=1
My interpretation of the results is that the streaming size threshold
isn't beneficial (actually seems to be very slightly detrimental) -so
we should just get rid of it. This tallies with some of the comments
Shawn & I had for the default value of streamFileThreshold in the
review for I862afd4c:
http://egit.eclipse.org/r/#patch,sidebyside,2040,2,org.eclipse.jgit/src/org/eclipse/jgit/transport/IndexPack.java
The perf-test code is here: https://gist.github.com/735402
It's a bit scruffy but basically does 10 runs (in randomised order)
for each threshold size on various packfiles, waiting a second
between each pack-indexing to allow GC to catch up. I know it's not
perfect - proper perf testing is hard to do :-)
For convenience provide an option to skip deletion of non-existing
files. Also add some tests for deletion methods in FileUtils.

If a treewalk walks also over index and the workingtree then the
IndexDiffFilter filter can be used which works much faster then
the semantically equivalent ANY_DIFF filter. This is because this
filter can better avoid computing SHA-1 ids over the content of
working-tree files which is very costly.
This fix will significantly improve the performance of e.g.
EGit's commit dialog.

next step is applied.

To improve runtime performance, caching the WorkingTreeOptions inside
of the Config object using the Config.SectionParser API allows
the WorkingTreeOptions to be accessed more efficiently whenever a
FileTreeIterator is constructed for the Repository.
Instead of passing the filemode handling option into isModified(),
the WorkingTreeIterator should always honor whatever setting has
been configured in this repository, as defined by its own copy of
the WorkingTreeOptions. This simplifies all of the callers as they
no longer need to lookup core.filemode on their own.
A few locations were changed from always using a hardcoded "true"
on the file mode to passing what is actually configured in the
repository. This is a behavior change, but corrects what should be
considered to be bugs as the core.filemode variable wasn't always
being used.

When indexing large blobs that are stored whole (non-delta form),
avoid allocating the entire blob in memory and instead stream it
through the SHA-1 checksum computation. This reduces the size
of memory required by IndexPack when processing very big blobs,
such as a 500 MiB uncompressable binary.
If the large blob already exists in the local repository, its
contents needs to be compared byte-for-byte after the entire pack
has been indexed, to ensure there isn't an unexpected SHA-1 collision
which may result in later data corruption. This compare is performed
as a streaming compare, again avoiding the large object allocation.
This change doesn't improve on memory utilization for large objects
stored as deltas. The change also doesn't improve handling for
any large commits, trees or annotated tags. There isn't much to
be done here for those objects, because they need to be passed down
to the ObjectChecker as a byte[]. Fortunately it isn't common for
these object types to be that large,

Its confusing that a new TreeWalk() needs to have reset() invoked

how TreeWalk was abused within ObjectWalk.

Existing application code which is still calling reset() will simply
