AdvertiseRefsHook is used to limit the visibility of the refs in Gerrit.
If this hook is not called, then all refs are treated as visible,
causing the server to serve commits reachable from branches the client
should not be able to access, if asked to via a request naming a guessed
object id.
This bug was introduced in v2.0.0.201206130900-r~123 (Modify refs in
UploadPack/ReceivePack using a hook interface, 2012-02-08). Stateful
bidirectional transports are not affected.
Fix it by moving the AdvertiseRefsHook call to
getAdvertisedOrDefaultRefs, ensuring the hook is called in all cases.
[jn: backported to stable-4.5 by splitting out tests and the protocol v2
specific parts]

When a server sends a ref advertisement using protocol v2 it contains
lines other than ref names and sha1s. Attempting to get the sha1 out
of such a line using the substring method can result in a SIOOB error
when it doesn't actually contain the sha1 and ref name.
Add a check that the line is of the expected length, and subsequently
that the extracted object id is valid, and if not throw an exception.

UploadPack has a setTransferConfig method which allows to set the
transfer config, however since the constructors of TransferConfig
have the default package visibility it is not possible for any
application using UploadPack, for example Gerrit, to actually set
a transfer config.
Make the constructors public. This is consistent with the public
constructors for example on PackConfig.

Annotate the parameter as @Nullable and set ProtocolV2Hook.DEFAULT

After cloning a repo with a submodule, non-recursively, JGit would
encounter in its TreeWalk in IndexDiff:
* first, a missing gitlink (in index & HEAD, not in working tree)
* second, the untracked folder (not in index and head, in working tree)
As a result, it would report the submodule as missing. Canonical git
reports a clean workspace.
The root cause of this is that the path of a gitlink "x" did
not compare equal to the path of a tree "x" in JGit.
Correct Paths.compare() to account for that. If two paths are otherwise
equal, then let gitlinks match both trees and files. Matching trees
solves the bug. Matching files is necessary to handle the case where
the gitlink directory was replaced by a file; see the new test case
IndexDiffSubmoduleTest.testSubmoduleReplacedByFile(). Comparisons of
unequal paths are left untouched, so the sort order is unchanged.
After the fix, another bug(?) in WorkingTreeIterator became apparent:
with core.dirNoGitLinks = true, it was no longer possible to overwrite
a gitlink in the index. This is now fixed in WorkingTreeIterator.
Add new test cases for the bug itself and for some related cases
(submodule directory deleted or replaced by a file) in
IndexDiffSubmoduleTest. Add a test for missing files in IndexDiffTest,
and adapt the PathsTest to test matching gitlinks.

when multiple match options are given in git describe the result must
not depend on the order of the match options. JGit wrongly picked the
first match using the match options in the order they were defined. Fix
this by concatenating the streams of matching tags for all match options
and then choosing the first match on the concatenated stream sorted in
tie break order.

This partially reverts commit a551b646: revert the changes in
RawParseUtils.lineMap(). Forcing all blobs containing a NUL byte
as a single line causes blame to produce useless results as soon
as it hits any version containing a NUL byte.
Doing binary detection at this level also has the problem that the
user cannot control it. Not by setting the text attribute nor in any
other way.
This came up in bug 541036, where a Java source inadvertently
contained NUL bytes in strings. Even fixing this by using escapes
"\000" will not fix JGit's blame for this file because the past
versions will still contain the NUL byte.
Native git can blame that file from bug 541036 fine.
Added new tests verifying that blaming a text file containing a NUL
byte produces sensible results.

From Oracle's "Defining an interface":
"All abstract, default, and static methods in an interface are
implicitly public, so you can omit the public modifier."
(Without any modifier, the interface methods are also abstract, so we
omit also the "abstract")
"In addition, an interface can contain constant declarations. All
constant values defined in an interface are implicitly public, static,
and final. Once again, you can omit these modifiers."
This makes the code more consistent. Now all interfaces under
org.eclipse.jgit follow the guidelines.

Add a new ssh client implementation based on Apach MINA sshd 2.0.0.
This implementation uses JGit's own config file parser and host entry
resolver. Code inspection of the Apache MINA implementation revealed
a few bugs or idiosyncrasies that immediately would re-introduce bugs
already fixed in the past in JGit.
Apache MINA sshd is not without quirks either, and I had to configure
and override more than I had expected. But at least it was all doable
in clean ways.
Apache MINA boasts support for Bouncy Castle, so in theory this should
open the way to using more ssh key algorithms, such as ed25519.
The implementation is in a separate bundle and is still not used in
the core org.eclipse.jgit bundle. The tests re-use the ssh tests from
the core test bundle.

Add support for git-receive-pack to the ssh git server and add two
new tests for pushing.
This actually uncovered an undocumented requirement in TransportSftp:
the FTP rename operation assumes POSIX semantics, i.e., that the
target is removed. This works as written only for servers that
support and advertise the "posix-rename@openssh.com" FTP extension.
Our little Apache MINA server does not advertise this extension.
Fix the FtpChannel implementation for Jsch to handle this case in a
meaningful way so that it can pass the new "push over sftp" test.
Add more tests to test the behavior of server host key checking.
Also refactor the tests generally to separate better the test
framework from the actual tests.

Suppose that a repository has the following commit graph:
B C
\ /
A
and it was cloned with --shallow-exclude=A. DepthGenerator does not mark
C as shallow, causing an invalid repository to be produced on the
client, because A is not sent. (A similar issue occurs when
--shallow-since is used to exclude A but neither B nor C.)
This happens whenever an excluded commit has more than one child that is
to be sent to the client. Fix DepthGenerator to handle this case
correctly.
While we're editing DepthWalk.Commit, fix the documentation of
DepthWalk.Commit#isBoundary.

Move the bulk of the basic parsing and host entry handling into a
new class OpenSshConfigFile that has no dependencies on any concrete
ssh implementation. Make the existing OpenSshConfig use the new
parser.
Introduce a new class SshConstants collecting all the various ssh-
related string literals. Also use TreeMaps with a case-insensitive
key comparator instead of converting keys to uppercase. Add a test
to verify that keys are matched case-insensitively.
Most of the parsing code was simply moved, except that the new
parser supports looking up entries given host name, port, and user
name, and can thus handle more %-substitutions correctly. This
feature is not yet used and cannot be used with JSch since JSch
only has a ConfigRepository.getConfig(String) interface.
The split is still worth the trouble as it opens the way to using
another ssh client altogether. Apache MINA sshd, for instance,
resolves host entries giving host name, port, and user name.
(Apache MINA has a built-in ssh config handling, but that has
problems, too: its pattern matching is case-insensitive, and its
merging of host entries if several match is not the same as in
OpenSsh. But with this refactoring, it will be possible to plug in
OpenSshConfigFile into an Apache MINA sshd client without dragging
along JSch.)
One test case that doesn't make sense anymore has been removed. It
tested that repeatedly querying for a host entry returned the same
object. That is no longer true since the caching has been moved to
a deeper level.
