Synchronize notifyConnectionError() so that only one exception is
handled and remove the ASYNC_BUT_ORDERED usage here. The
ASYNC_BUT_ORDERED was added with 7d2c3ac9f ("Do not call synchronized
methods in reader/writer thread"), but is no longer necessary, since
the Semaphores where replaced with conditions in the previous commit.
This continues the design started with e98d42790 ("SmackReactor/NIO,
Java8/Android19, Pretty print XML, FSM connections"), where the
exceptions that caused an operation to fail, are not recorded within
SynchronizationPoint but within the connection instance itself.
Since d65f2c932 ("Bump Error Prone version to 2.3.4 and fix new bug
patterns") the channel selected callback is no longer a final field of
the connection instance, hence it may be come null even if the
connection instance is still strongly referenced. Also the
ConnectionAttemptState class uses simply a lambda as callback, which
is also not strongly referenced otherwise.
The "channel selected" callback was wrapped in weak reference, so that
connection instances could get gc'ed if they are still connected but
the user lost all references to them. In this case, the weak reference
to the connection instance would become 'null' and
selectionKey.cancel() would be called.
This change means that a socket and its selection key of a "leaked"
connected connection instance continues to be part of the reactor. But
this may not be that bad: first, users are expected to manager their
connection instances, and disconnect them before they are
discarded. And secondly, at some point the connection likely will get
disconnected, and in this case, the socket and its selection key will
be removed from the reactor.
This moves the logic in AbstractXMPPConnection.getSmackTlsContext()
into the ConnectionConfiguration constructor.
Also introduce SslContextFactory and use it in
ConnectionConfiguration.
The field XMPPInputOutputStream.flushMethod was not initialized, which
could cause an NPE in the "switch (flushMethod)" found in
Java7ZlibInputOutputStream.getOutputStream().
Apply builder pattern to form fields and replace getVariable() with
getFieldName(). Refer to the field name as "field name" instead of
"variable" everyone, just as XEP-0004 does.
Improve the high-level form API: introduce FilledForm and FillableForm
which perform stronger validation and consistency checks.
Also add FormFieldRegistry to enable processing of 'submit' forms
where the form field types are omitted.
Smack also now does omit the form field type declaration on 'submit'
type forms, as it is allowed by XEP-0004.
The initState() method is also called in disconnect(). And if we reset
the closingStreamReceived sync point at disconnect, it will break the
WaitForClosingStreamElementTest integration test.
Return false as soon as the hashed value does not match. This is
sound, since every class that implements equals(Object) should also
implement hashCode().
This method was removed with 07da9ffb4 ("Do not have
Stanza.getExtension(String, String) return a generic type"). In order
to aide migration to the newer API, this commit re-adds the method and
marks it as deprecated.
This also removes the powermock dependency. Although powermock is a
fine library, it currently prevents dropping Junit4. And since we only
use the Whitebox API of powermock, this simply replaced powermock's
Whitebox with our own.
Ensure that he returned extension element is actually of the correct
type. It should not be common, but in theory, Smack's provider
architecture would allow for different types to be returned than the
ones one may expect.
The code in the integration-test/ directories should either be
migrated to sinttest (or unit tests), or get deleted. This is a first
small step towards this goal.
Returning a generic would allow for
List<ExtensionElement> list = stanza.getExtension("foo", "bar");
to compile (Note the we are calling getExtension(), not
getExtension*s*()).
Users are encouraged to use the type safe getExtension(Class<? extends
ExtensionElement) variant instead.
Fixes SMACK-825.
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.
This Commit is was in response to SMACK-839.
It appears that we observe a partion GC run on some systems,
especially ones with few resources. Hopefully this increases the
chances to observe the expected GC affects so that the unit test
passes also on those systems.
Because an failing test on Travis was observered using a timeout of
60s:

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.
Smack will throw an IllegalArguementException if extremely
long reply timeouts are tried to be set. I assumed currentTimeMilli()
to be the boundary condition as per SMACK-718
in case length is zero. Also do throw a NegativeArraySizeException if
length is negative instead of returning null.
This fixes the following sporadic test issue:
