Introducing Smack's own XmlPullParser interface which tries to stay as
compatible as possible to XPP3. The interface is used to either wrap
StAX's XMLStreamReader if Smack is used on Java SE, and XPP3's
XmlPullParser if Smack is used on on Android.
Fixes SMACK-591.
Also introduce JUnit 5 and non-strict javadoc projects.
to clean up the state build up by connect().
Related to SMACK-855 there is the possiblitiy of a stray (writer)
thread if, for example, tlsHandled.checkifSuccessOrWaitorThrow() in
XMPPTCPConnection.connectInternal() throws. This commit should prevent
that.
This commit adds
- SmackReactor / NIO
- a framework for finite state machine connections
- support for Java 8
- pretty printed XML debug output
It also
- reworks the integration test framework
- raises the minimum Android API level to 19
- introduces XmppNioTcpConnection
Furthermore fixes SMACK-801 (at least partly). Java 8 language
features are available, but not all runtime library methods. For that
we would need to raise the Android API level to 24 or higher.
Before this, if there was a stream error response by the server to our
stream open, that error response would only be handled in the reader
thread, and the user would get a message like:
"org.jivesoftware.smack.SmackException$NoResponseException: No
response received within reply timeout. Timeout was
5000ms (~5s). While waiting for SASL mechanisms stream feature from
server"
while the server may actually sent something like
<stream:stream
xmlns='jabber:client'
xmlns:stream='http://etherx.jabber.org/streams'
id='6785787028201586334'
from='jabbim.com'
version='1.0'
xml:lang='en'>
<stream:error>
<policy-violation xmlns='urn:ietf:params:xml:ns:xmpp-streams'>
</policy-violation>
<text xml:lang='en' xmlns='urn:ietf:params:xml:ns:xmpp-streams'>
Too many (2) failed authentications from this IP
address (1xx.66.xx.xxx). The address will be unblocked at 04:24:00

</text>
</stream:error>
</stream:stream>
It was necessary to change saslFeatureReceived from SmackException to
XMPPException in order to return the StreamErrorException at this sync
point. But this change in return required the introduction of a
tlsHandled sync point for SmackException (which just acts as a wrapper
for the various exception types that could occurn when establishing
TLS). The tlsHandled sync point is marked successful even if no TLS
was established in case none was required and/or if not supported by
the server.
The pattern
if (now > deadline) break;
wait(deadline - now);
is insufficient in case "now == deadline" because the result would be
wait() being called with 0, which would mean "wait until
notified". Thus, the timeout would become infinite.
This adds the ability to provide a distinct authorization identifier for use
by SASL mechanisms. Not all SASL mechanisms support this operation, in
particular CRAM-MD5.
Both the javax and provided SASL implementations are extended, and an authzid
parameter added to the authenticate method.
The authorization identifier is passed as a EntityBareJid in order to assure the
correct form.
Resolves SMACK-677.

Instead of extending SocketFactory, the proxy support classes now
implement ProxySocketConnection. This removes a lot of unnecessary
code.
Also re-enables proxy support, which was broken in previous versions
because none of extended SocketFactories did override
createSocket() (SMACK-683).
Add
- performSaslAnonymousAuthentication()
- performSaslExternalAuthentication(SSLContext)
- addEnabledSaslMechanism(String)
- addEnabledSaslMechanisms(Collection<String>)
to ConnectionConfiguration.Builder.
Instead of providing a special API call for anonymous authentication,
Smack now has a configuration builder method to set anonymous/external
authentication. This also removes a lot of duplicate code within
Smack.
Also move SASLAnonymous into o.j.smack.sasl.core.
Fixes SMACK-629.
