Most callers/users of TemporaryBuffer are sizing the in-memory
portion large enough that most outputs fit into RAM. With this
assumption they don't pay close attention to the size of IOs
being written, as it "should" just be a copy from one byte array
to another.
Overflow sets up a local file handle, which is costly to write to
for small IO units. Wrap the local file in a BufferedOutputStream
to combine small writes together. Larger writes can still bypass the
buffer as BOS automatically avoids copying for larger writes.

When reading back from an overflowed TemporaryBuffer the InputStream
must be closed to close the FileInputStream that is reading from

By writing the temporary overflow merge result to $GIT_DIR JGit
can ensure the same filesystem permissions apply to protect the
file contents.
If no directory is available from the repository (e.g. DfsRepository)
null will be passed and the system temporary directory will be used
instead.

Formatting merge conflicts one byte at a time is going to be very
slow when the final OutputStream is a FileOutputStream and the JVM
is making system calls for each byte output.
When outputting a range of bytes from a byte[] the bol (beginning
of line) value only depends on the value of the last byte written.
Other bytes in the array can be passed directly to the lower stream
for more efficient output.

When RecursiveMerger found that there are multiple base-commits for the
commits to be merged it tries to temporarily merge the base commits. But
if these base commits have no common predecessor there was a bug in JGit
leading to a NPE. This commit fixes this by enforcing that an empty tree
is used as base when merging two unrelated base commits.
This logic was already there when merging two commits which have no
common predecessor (ThreeWayMerger.mergeBase()). But the code which was
computing a new temporary base commit in case of criss-cross merges
didn't take care to pick an empty tree when no common predecessor can be
found.

This reverts commit 6bc48cdc62.
Until git v1.7.10.2~29^2~1 (builtin/merge.c: reduce parents early,
2012-04-17), C git merge would make merge commits with duplicate parents
when asked to with a series of commands like the following:
git checkout origin/master
git merge --no-ff origin/master
Nowadays "git merge" removes redundant parents more aggressively
(whenever one parent is an ancestor of another and not just when
duplicates exist) but merges with duplicate parents are still permitted
and can be created with git fast-import or git commit-tree and history
viewers need to be able to cope with them.
CommitBuilder is an interface analagous to commit-tree, so it should
allow duplicate parents. (That said, an option to automatically remove
redundant parents would be useful.)

The block pointer list may have been relatively large, so no need to
make more garbage. Instead, just clear the list and null out all the
elements.
Another possible motivation: a caller may have provided an inaccurate
estimated size, so the list might have been resized several times. If
the list is reused later for a similarly underestimated workload, this
fix will prevent additional resizing on subsequent usages.

Callers may wish to use TemporaryBuffer as an essentially unbounded
buffer by passing Integer.MAX_VALUE as the size. (This makes it
behave like ByteArrayOutputStream, only without requiring contiguous
memory.) Unfortunately, it was always allocating an array in the
backing block pointer list to hold enough blocks to MAX_VALUE--all
262,016 of them. It wasn't allocating the blocks themselves, but this
array was still extremely wasteful, using about 2MiB of memory on a
64-bit system.
Tweak the interface to specify an estimated size, and only allocate
the block pointer list enough entries to hold that size. It's an
ArrayList, so if that estimate was wrong, it'll grow. We assume the
cost of finding enough contiguous memory to grow that array is
acceptable.
While we're in there, fix an off-by-one error: due to integer division
we were undercounting the number of blocks needed to store n bytes of
data as (n / SZ).

Since 27ae8bc65 Git has implemented AutoCloseable, which means Eclipse
may warn if close() is never called on a Git instance. For example,
the following would result in a resource warning:
Repository repo = openRepository(foo);
Git git = new Git(repo);
try {
git.someCommand().call();
} finally {
repo.close();
}
(The same warning would occur if repo were created in a try-with-
resources block.)
The "obvious" fix is to open git in a try-with-resources block:
try (Repository repo = openRepository(foo);
Git git = new Git(repo)) {
git.someCommand().call();
}
Unfortunately, this construction was subtly broken: it would call both
git.close() and repo.close(), but git.close() would call repo.close()
again. Depending on the repository implementation, this might or might
not be ok. If it's not ok, it might not immediately cause an error, if
the reference count of repo was >2 at the time of closing.
Of course, explicitly calling git.close() followed by repo.close() in
two finally blocks has had the same double-closing problem since
forever. But the problem became worse when Git started implementing
AutoCloseable, because now Eclipse is _actively encouraging_
developers to change working code into broken code.
To work around this, keep track in Git's constructor of whether the
repository was passed in or opened at construction time, and only
close the repository if it was opened by Git.
Note that in the original example, there was not _actually_ a resource
leak, since repo was closed exactly once; git did not _need_ to be
closed in this case. But at least fixing this false-positive warning
no longer introduces a real bug.

Current ArchiveCommand design doesn't allow to pass in options to

implement custom format implementation (it cannot be derived from

the options using ThreadLocal, before the method
ArchiveOutputStream createArchiveOutputStream(OutputStream s)
is get called.
This change extends the ArchiveCommand.Format by allowing to pass
option map during creation of ArchiveOutputStream.
ArchiveCommand is extended correspondingly. That way client can
easily pass options to the underlying streams:
Map<String, Object> level = ImmutableMap.<String, Object> of(
"level", new Integer(9));
new ArchiveCommand(repo)
.setFormat("zip")
.setFormatOptions(level)

ObjectInserter recently learned to read back inserted objects before
they have been flushed. It is in general unsafe to create refs to such
objects, but it is now much more possible to do so, by passing "new
RevWalk(inserter.newReader())" into RefUpdate#execute(RevWalk).
We can't change the RefUpdate interface to remove execute(RevWalk);
nor would we necessarily want to, for performance reasons. And in any
case, RefUpdate#safeParse explicitly ignores MissingObjectExceptions.
But we can enforce object existence in InMemoryRepository, which will
allow callers using this class in their tests to ensure they are using
the RefDatabase correctly.

SystemReader used a chached ObjectChecker which was instantiated only
once. But in case of unit tests where we can change the platform
dynamically (e.g. MockSystemReader.setWindows()) this is wrong and
caused DirCacheCheckoutMaliciousPathTest.
testMaliciousAbsoluteCurDrivePathWindowsOnUnix() to fail. This change
allows
user of SystemReader to force the creation of a new ObjectChecker.
MockSystemReader.setWindows() and .setUnix() make use of this feature.

Mac's HFS+ folds concatentations of ".git" and ignorable Unicode
characters [1] to ".git" [2]. Hence we need to disallow all names which
could potentially be a shortname for ".git". Example: in an empty
directory create a folder ".g\U+200Cit". Now you can't create another
folder ".git".
The following characters are ignorable Unicode which are ignored on
HFS+:

Windows creates shortnames for all non-8.3 files (see [1]). Hence we
need to disallow all names which could potentially be a shortname for
".git". Example: in an empty directory create a folder "GIT~1". Now you
can't create another folder ".git".
The path "GIT~1" may map to ".git" on Windows. A potential victim to
such an attack first has to initialize a git repository in order to
receive any git commits. Hence the .git folder created by init will get
the shortname "GIT~1". ".git" will only get a different shortname if the
user has created a file "GIT~1" before initialization of the git
repository.

Windows treats "foo." and "foo " as "foo". The ".git" directory is
special, as it contains metadata for a local Git repository. Disallow
variations that Windows considers to be the same.

The component name ".GIT" inside a tree entry could confuse a
case insensitive filesystem into looking at a submodule and
not a directory entry.
Disallow any case permutations of ".git" to prevent this
confusion from entering a repository and showing up at a
later date on a case insensitive system.

If the DirCache contains a path that is known to be invalid, refuse to
read the DirCache into memory. This avoids confusing errors later if
an invalid path read from the DirCache were to be passed into a new
DirCacheEntry constructor.

isValidPath is an older simple form of the validation performed by
checkValidPath. Use the latter as it more consistently matches
git-core's validation rules.
By running the same validation as fsck, callers creating an entry
for the DirCache are more likely to learn early they are trying
to build trees that will fail fsck.

When updating a submodule (e.g. during recursive clone) the repository
for the submodule should be located at <gitdir>/modules/<submodule-path>
whereas the working tree of the submodule should be located at
<working-tree>/<submodule-path> (<gitdir> and <working-tree> are
associated to the containing repository). Since CloneCommand has learned
about specifying a separate gitdir this is easy to implement in
SubmoduleUpdateCommand.

This feature is needed to support the new submodule layout where the

Native git's "init" command allows to specify the location of the .git
folder with the option "--separate-git-dir". This allows for example to
setup repositories with a non-standard layout. E.g. .git folder under
/repos/a.git and the worktree under /home/git/a. Both directories
contain pointers to the other side: /repos/a.git/config contains
core.worktree=/home/git/a . And /home/git/a/.git is a file containing
"gitdir: /repos/a.git". This commit adds that option to InitCommand.
This feature is needed to support the new submodule layout where the
.git folder of the submodules is under .git/modules/<submodule>.

The bulk of the "is this sane" logic is inside of ObjectChecker. The
only caller for the version in DirCacheCheckout is an obtuse usage for
the static isValidRefName() method in Repository.
Deprecate the weird single use method in DirCacheCheckout and move all
code for checking a sequence of path components into ObjectChecker,
where it makes sense alongside the existing code that checks a single
component at a time.
Reuse a single ObjectChecker for the local platform, to avoid looking
up the system properties on each path string considered.

If the text extent height of a to be rendered plot line is odd, then the
SWTPlotRenderer cannot calculate the correct Y position for drawing the
label and draws the label with a 1 pixel offset. SWT text drawing uses
the baseline as Y coordinate. Due to the given centerline API in the
AbstractPlotRenderer the overall calculation of the baseline for SWT is
effectively (height / 2) * 2, thereby rounding all odd heights downward
to the next even number.
This change pushes the division by 2 from the caller into the
implementations of drawText. A corresponding change will be pushed in
the egit repository.
