Signal early command termination due '-h' or '--help' option via
TerminatedByHelpException. This allows tests using
CLIGitCommand differentiate between unexpected command parsing errors
and expected command cancellation "on help" (which also allows
validation of expected/unexpected help messages).
Additional side-effect: jgit supports now git style of handling help
option: any unexpected command line options before help are reported as
errors, but after help ignored.

This will execute git commands (with arguments) specified on the command
line, handy for developing/debugging a sequence of arbitrary git
commands working on same repository.
The git working dir path can be specified via Java system property
"git_work_tree". If not specified, current directory will be used.

JGit CLI should allow to do this: checkout -- <path>
Currently, even if "a" is a valid path in the git repo, jgit CLI can't
checkout it:
$jgit checkout -- a
error: pathspec 'a' did not match any file(s) known to git.
The fix also fixes at same time "unnamed" zombie "[VAL ...]" argument
shown on the command line.
Before fix:
$jgit -h
jgit checkout name [VAL ...] [-- path ... ...] [--force (-f)] [--help
(-h)] [--orphan] [-b]
After fix:
$jgit -h
jgit checkout [name] [-- path ... ...] [--force (-f)] [--help (-h)]

When setting timeout on push, BasePackConnection creates a timer, which
will be terminated when push finishes. But, when using
SmartHttpPushConnection, it dropped the first timer created in the
constructor and then created another timer in doPush. If new threads are
created faster than the gc collects then this may stop the service if
it's hitting the max process limit. Hence don't create a new timer if it
already exists.

PathFilter and PathFilterGroup form JGit's implementation of git's
path-limiting feature in commands like log and diff. To save time
when traversing trees, a path specification
foo/bar/baz
tells the tree walker not to traverse unrelated trees like qux/. It
does that by returning false from include when the tree walker is
visiting qux and true when it is visiting foo.
Unfortunately that test was implemented to be slightly over-eager: it
doesn't only return true when asked whether to visit a subtree "foo"
but when asked about a plain file "foo" as well. As a result, diffs
and logs restricted to some-file/non-existing-suffix unexpectedly
match against some-file:

Fix it by checking against the entry's mode.
Gitiles +log has the same bug and benefits from the same fix.
Callers know not to worry about what subtrees are included in the tree
walk because shouldBeRecursive() returns true in this case, so this
behavior change should be safe. This also better matches the behavior
of C git:
$ empty=$(git mktree </dev/null)

Expand the existing PathFilterGroup tests to check which paths the
tree entry matches. This expands test coverage by ensuring that
PathFilterGroup's simpler code path to match against a single
PathFilter works correctly.
While at it, move the check on tree entry d/e/f/g.y into two separate
tests: one to check that it doesn't match any of the configured paths,
and another to check that it does not throw StopWalkException to end
the walk early.

Pushing with JGit commandline to e.g. Github failed with "unauthorized"
since HttpUrlConnection calls the configured authenticator implicitly.
The problem is that during a push two requests are sent to the server,
first a GET and then a POST (containing the pack data). The first GET
request sent anonymously is rejected with 401 (unauthorized). When an
Authenticator is installed the java.net classes will use the
Authenticator to ask the user for credentials and retry the request.
But this happens under the hood and JGit level code doesn't see that
this happens.
The next request is the POST but since JGit thinks the first GET request
went through anonymously it doesn't add authentication headers to the
POST request. This POST of course also fails with 401 but since this
request contains a lot of body-data streamed from JGit (the pack file!)
the java.net classes can't simply retry the request with authorization
headers. The whole process fails.
Fix this by using Apache httpclient which doesn't use Authenticator to
retrieve credentials. Instead initialize TransportCommand to use the
default credential provider if no other credentials provider was set
explicitly. org.eclipse.jgit.pgm.Main sets this default for the JGit
command line client.

If an application uses PushConnection directly on the native Git wire
protocols JGit should send along the application's expected oldId, not
the advertised value. This allows the remote peer to compare-and-swap
since it was not tested inside JGit.
Discovered when I tried to use a PushConnection (bypassing the
standard PushProcess) and the client blindly overwrote the remote
reference, even though my app had supplied the wrong ObjectId for
the expectedOldObjectId. This was not expected and cost me over an
hour of debugging, plus "corruption" in the remote repository.
By passing along the exact expectedOldObjectId from the app the
remote side can do the check that the application skipped, and
avoid data loss.

JGit's Nullable type was added[1] in the hope of being able to add
nullness annotations that (a) do not preclude building and running
with Java 7 and (b) could be shared by Gerrit, which uses a custom
Nullable type for other reasons[2]. Sharing a type is useful because
Eclipse's null analysis is only able to use one Nullable type at a
time in a given workspace (so for this analysis to function in a
workspace used to develop Gerrit, JGit and Gerrit would need to use
the same Nullable type).
The new Nullable type has CLASS instead of RUNTIME retention because
there wasn't any obvious use for the annotation at run time.
Gerrit uses the Nullable annotation to communicate with Guice. Guice
injection happens at runtime, so it needs to be able to read the
@Nullable annotations at run time[3]. Otherwise Guice produces
provisioning errors, such as
3) null returned by binding at com.google.gerrit.lucene.LuceneChangeIndex$Factory.create()
but parameter 7 of com.google.gerrit.lucene.LuceneChangeIndex.<init>() is not @Nullable
Switch to RUNTIME retention to avoid this.
While at it, update the javadoc to explain more clearly how this
annotation relates to other Nullable types[4]. This should make it
clearer why JGit needed another Nullable type:
A. Avoiding dependency on Java 8
B. RUNTIME retention to allow Guice to read the annotation at run time
C. Named Nullable so Guice can recognize the annotation
D. Not an addition to Java EE's javax.annotation package, to avoid
the split-package problem[2] that prevents the annotation from
being readable at run time when loaded from an OSGi container
E. Avoiding heavyweight dependencies, deprecated dependencies, and
dependencies on package internals

This should mirror the behavior of `git push --atomic` where the
client asks the server to apply all-or-nothing. Some JGit servers
already support this based on a custom DFS backend. InMemoryRepository
is extended to support atomic push for unit testing purposes.
Local disk server side support inside of JGit is a more complex animal
due to the excessive amount of file locking required to protect every
reference as a loose reference.
