When a user tried to use a service not enabled in the remote server
a misleading error message was given:
fatal: remote error: Git access forbidden
This patch modifies the error message to make the cause clearer
to the user. Now, when the user tries to use a not enabled service,
the message error clearly states it:
fatal: remote error: Service not enabled

This was deprecated and should only be used by DirCacheCheckout and
friends. Other classes should use SystemReader.checkPath() instead.

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
the backing file.

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.

CherryPickCommand only works on a non-bare repository, as it must
modify the working tree and index in case of a merge conflict. In
tests, being able to recover from a merge conflict is less important,
as the caller should be able to control the full contents of files in
advance of the cherry-pick.

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.
