Since using a pipe, as we did previously would not error the target if
the first command in the pipe fails.
It is still far from ideal, since the dot file is also generated if
the gradle command fails. At some point, this should probably become
part of gradle build step instead of shelling out to a Makefile.
- Reduce the amount of types that are subtypes of NamedElement. See
javadoc of NamedElement for rationale.
- Work more with XmlEnvironment in XmlStringBuilder.
- Some minor changes to XmlStringBuilder API.
This is based on the patch provided by Georg Lukas, modified to take
XMPP domain names that can not be represented as DNS names into
account. See c42d2eea24 (r269250137)
Fixes SMACK-870.
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.
and also call notifyConnectionError() on exception thrown by
openStream().
In hindsight I wonder why openStream() was ever called in the writer
thread, as it only caused unnecessary synchronization overhead, as can
be seen by the initialOpenStreamSend synchronization point.
In case an exception happens in connect()/login() the
'disconnectedButResumable' boolean may (still) be set. Which causes
only one of the reader and writer threads to exit, typically the
reader thread, because shutdown() will bail out very early. This
leaves a dangling (writer) thread causing memory leaks and deadlocks
on a subsequent connect()/login().
as it is not neccessary and causes stalls and deadlocks with a
concurrent connect()/login() (which could be resolved interrupting the
connect()/login() calling thread):

If a stream resume fails, smack will re-send all queued stanzas after a
reconnect. However, it does not make sense to re-send them:
* IQs / IQ responses have probably timed out
* MUC messages and PMs will be rejected as you haven't rejoined yet
* regular messages should be amended with a <delay> element
This patch adds a StanzaDroppedListener interface to the
XMPPTCPConnection. If at least one StanzaDroppedListener is provided,
all queued messages will be drained into the StanzaDroppedListener(s).
Otherwise, the original behavior of attempting to transmit them will be
followed.

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.
The inetAddressAndPort String is redundant since
a2743549b8, because we now construct the
InetSocketAddress earlier and can hence use it in the log statement.
The purpose of the "maybeCompressFeaturesReceived" synchronization
point is to wait for the stream features after authentication. This is
not really reflected by its name and furthermore its
checkIfSuccessOrWait() method was only invoked if compression was
enabled, but we always want to wait for the stream features after
authentication. Hence move the call before the isCompressionEnabled()
check and one layer up in the call stack.
Fixes SMACK-846.
using the default algorithm. Instead continue with 'null' as value of
the KeyManager[] array (kms). This makes the SSLContext.init() methods
to search the default security providers for implementations, which is
also OK.
This change is needed because it appears that on Android
KeyManagerFactory.getDefaultAlgorithm returns 'SunX509', which
subsequently results in

Note that this is possibly because the Secuurity Provider was
not (yet) intialized.
New stanzas sent directly after stream resumption might have been added
to unacknowledgedStanzas before the old unacknowledged stanzas
are resent. This caused new stanzas to be sent twice and later led
to a StreamManagementCounterError.

return value of parser.getName().
Also perform the access to 'parser' on a different LOC than
equals(). This should help debugging things like
