This is a complete redesign of what was previously
XmppNioTcpConnection. The new architecture allows to extend an XMPP
client to server (c2s) connection with new transport bindings and
other extensions.
By not directly depending on Bouncycastle (BC), we avoid conflicts between
different bouncycastle versions. It is also part of the developers job
to take care that all required security primitives are available. If
they are provide by BC or some other security provider should not be
up to Smack to decide.
We now only add BC as test dependency to satisfy this requirement when
the unit tests are executed.
Instead of marking the handle as not running by setting the handler's
value in the map to false, we now remove simply the key if there is no
handler running. This also means we no longer need to use a weak hash
map for this.
Also reduce the size of the synchronized blocks, mainly by scheduling
the handler outside of the synchronized(threadActiveMap) block.
Make some code better readable and add some more comments. Also do
start a new handler thread if the task threw.
If we do not peek at the scheduled actions in the reactors
synchronized block, then there is a kind of lost-update problem. While
Ractor.schedule() will call wakeup() on the selector, a thread could
have already determined the value of selectWait, while being blocked
at the start of the synchronized reactor section. Once it is able to
enter the section, it will use an outdated selectWait value.
This leads to scheduled actions not being executed on time.
Thanks to Eng ChongMeng for reporting this and suggesting the fix.
Besides the way the transport handles the stream after SASL
<success/>, the SASL logic is independend from the underlying
transport (BOSH, TCP, …). Hence move it up into
AbstractXMPPConnection.
This also has the benefit that we can make some more methods private
or package-private.
Also introduce XmlStringBuilder.optTextChild(), which causes some
associated changes.
Thanks to PolFW, who writes:
A SASLErrorException is thrown before we have received the "<success
xmlns='urn:ietf:params:xml:ns:xmpp-sasl'/>". This is because
SASLAuthentication is keeping a reference to a "saslException" so to
clear that after a authentication failure we have to invoke again
connect on the xmpptcpconnection to initialize again the
saslAuthentication. But it doesn't solve the issue because an
AlreadyConnectedException is thrown before the initialisation of the
"this.saslAuthentication.init();"
Note that the user uses one time tokens for authentication.
and FileTestUtil in favor of commons-io. This is required because
Eclipse won't put src/test code into the classpath of src/main
code (even though gradle was configured with an according
dependency).
- 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 patch makes it possible to change the stream-level language as part
of the connection configuration, to allow a properly implemented
entities to provide i18n'ed response messages. The Locale type is used
for this configuration, and the effective language string can be
obtained via `ConnectionConfiguration.getXmlLang()`.
This code does not cover XMPPBOSHConnection!

and not NullPointerException. Altough this differs from
java.util.Objects behavior, throwing an IllegalArgumentException
appears more sensible and makes it easier to catch it in Smack's
parsing function.
Without this, newly scheduled runnables would potentially not be
scheduled in case the reactor thread was blocking in select(0)
indefinetly.
Thanks to Eng ChongMeng for reporting this.
As result it is now also possible to start multiple local SOCKS5
proxies with different port, which is usually not necessary in real
life but useful for unit tests.
'parseAndProcessStanza()' throws generic Exceptions.
Since there are plenty of exceptions that should not be
catched by smack, it's better to throw Type Specific Exceptions.
