JGit now considers lightweight tags only if the --tags option is set
i.e. `git.describe().setAllTags(true)` has to be set, else the default
is now as in c git:
Only annotated tags are evaluated unless you pass true
equivalent to --tags (or --all) by the option setAllTags.
Hint: This (still) doesn't address any difference between c-git
`--all` and `!--all --tags` behavior;
perhaps this might be a follow up request

Jsch checks only for the availability of the algorithms given by
Jsch-internal config keys "CheckCiphers", "CheckKexes", and
"CheckSignatures". If the ssh config defines any algorithms
unknown to Jsch not listed in those keys, it'll still propose them
during the negotiation phase, and run into an NPE later on if the
server happens to propose such an algorithm and it gets chosen.
Jsch reads those "CheckCiphers" and the other values from either a
session-local config, or the global static Jsch config. It bypasses
~/.ssh/config for these values.
Therefore, copy these values from the config as read from
~/.ssh/config into the session-specific config. That makes Jsch
check _all_ configured algorithms up front, discarding any for
which it has no implementation. Thus it proposes only algorithms
it actually can handle.

From the javadoc for Files.list:
"The returned stream encapsulates a DirectoryStream. If timely disposal
of file system resources is required, the try-with-resources construct
should be used to ensure that the stream's close method is invoked
after the stream operations are completed."
This is the only call to Files#newDirectoryStream that is not already in
a try-with-resources.

DescribeCommand still uses the deprecated method and is not adapted in

Make FileTreeIterator not enter ignored directories by default. We
only need to enter ignored directories if we do some operation against
git, and there is at least one tracked file underneath an ignored
directory.
Walking ignored directories should be avoided as much as possible as
it is a potential performance bottleneck. Some projects have a lot of
files or very deep hierarchies in ignored directories; walking those
may be costly (especially so on Windows). See for instance also bug
500106.
Provide a FileTreeIterator.setWalkIgnoredDirectories() operation to
force the iterator to iterate also through otherwise ignored
directories. Useful for tests (IgnoreNodeTest, CGitIgnoreTest), or
to implement things like "git ls-files --ignored".
Add tests in DirCacheCheckoutTest, and amend IndexDiffTest to test a
little bit more.

Declare Repository#notifyIndexChanged() final and
Repository#notifyIndexChanged(boolean) abstract to force implementors
to switch to overriding the latter method. This makes Repository less
error-prone to extend since implementors no longer need to remember to
override one of those two methods.

e9e150fdd2 (Store in IndexChangedEvent if it was caused by JGit
itself, 2018-05-13) modified Repository#notifyIndexChanged to take a
boolean argument to indicate whether the index change happened under
the current process's control or externally, for use by EGit. In
other words, the function signature changed from
public abstract void notifyIndexChanged();
to
public abstract void notifyIndexChanged(boolean internal);
Callers outside JGit itself notifying a Repository about index changes
are expected to be rare, so this is not very disruptive to them. In
most cases they would be notifying about changes that they made
themselves, so treating their notifyIndexChanged() calls as
notifyIndexChanged(true) should be relatively safe.
Implementors have the opposite problem: adding the new "abstract void
notifyIndexChanged(boolean)" method means they are obligated to
override it. Add a default implementation that calls their existing
override of notifyIndexChanged() to make their migration easier.
The main downside is that authors of new Repository subclasses that
do not realize they need to override notifyIndexChanged would end up
with a default implementation which calls notifyIndexChanged(true),
in turn calling notifyIndexChanged() again and so on, resulting in
StackOverflowException. Add an implementors' note to the class
Javadoc to avoid this issue. A followup commit will force
implementors to adapt to the new API by changing the methods to
@Deprecated
public final void notifyIndexChanged() {
notifyIndexChanged(true);
}
public abstract void notifyIndexChanged(boolean internal);

Refs are not advertised as part of the protocol v2 capability
advertisement. Don't call AdvertiseRefsHook.
Noticed because many implementations of AdvertiseRefsHook read all
refs in order to call UploadPack#setAdvertisedRefs, causing the
capability advertisement to be as slow as a v0 ref advertisement with
some RefDatabase implementations.
Such an AdvertiseRefsHook is of dubious utility (a better place to
determine which refs are advertised is in the RefDatabase
implementation itself, as in Gerrit), but at any rate since it's not
bringing about any benefit here, we can skip the hook call.

With this patch, a server spawned by "jgit daemon" can be accessed using
protocol v2 from a Git client that supports it (for example, "git" with
the appropriate patches). This is only activated if the repository's
config has "protocol.version" be 2.
This required a change to the package-private #execute methods in
DaemonService to allow passing of extra parameters.
This has been tested with a patched Git.

Add support for the "include-tag" parameter in the "fetch" command in

In order to determine which tags to include, only objects pointed to by

performance reasons and to match the behavior of Git (see add_ref_tag()
in builtin/pack-objects.c).

When OPTION_INCLUDE_TAG is set, UploadPack#sendPack uses the #refs
instance variable as a source of information of tags. A subsequent patch
will need to supply this information to #sendPack without
modifying #refs, so refactor #sendPack to take in this information
through a parameter instead.
Note that prior to this patch, #refs was used twice in #sendPack: once
to generate the argument to PackWriter#setTagTargets, and once to
determine if any tags need to be included in the packfile. This patch
only updates the latter use, since the former is meant not only for
"true" tag targets but any object that should be hoisted earlier during
packing (see the documentation of PackWriter#setTagTargets).
This patch does not introduce any functionality change.
