ExtensionElement is now a marker interface that requires all
implementation non-abstract classes to carry a static final QNAME
field (of type QName). This is verified by a new unit test.
Also FullyQualifiedElement is renamed to simply XmlElement. XmlElement
is used over ExtensionElement when implementing classes do not
statically know the qualified name of the XML elements they
represent. In general, XmlElement should be used sparingly, and every
XML element should be modeled by its own Java class (implementing
ExtensionElement).
This also resulted in a refactoring of the Providers and parsing
Exceptions. NumberFormatException and ParseException can now be thrown
directly, the wrapping in a SmackParsingException is down at a higher
layer, i.e. in AbstractProvider.
InBandBytestreamManager followed an unusual pattern: Within the
connectionTermianted() callback, it would remove itself from the
'managers' map. This allowed for multiple instances of an
InBandBytestreamManager to exist for the same connection, causing all
kinds of issues.
This fixes the issue by changing InBandBytestreamManager to use the
Smack-idiomatic pattern used by managers.
We also do no longer reset the listeners if the connection is
termianted, as listeners (and handlers) typically persist until they
are explicitly removed by the user.
As positive side-effect, the number of indeterministic unit-tests,
caused by using Thread.sleep(), is reduced. The executor service in
InitiationListener was also removed, because the IQ handler is already
called asynchronously to the connections main loop.
Thanks to Anno van Vliet for reporting this.
`mgr.getNode(...)` method is not supposed to throw any type
of exception. It threw two kinds of exceptions: `NotConnectedException`
and `SmackException`.
By using `ThreadedDummyConnection.newInstance()` method,
`NotConnectedException` can be removed. And `SmackException`
can be removed by correctly building the DiscoverInfo packet.
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.
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.
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 commit will enable user to communicate
information about music to which user is listening.
This feature is less of a requirement and more like fun to me.
An attempt at solving SMACK-257.
Incase you see any chances of improvement,
please let me know :)
- 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.
Although it it not that unreliable, it causes false negatives once in
a while. This is because the standard Java SE API does not provide a
way to force a *full* garbage collection run, we need to resort to
unreliable hacks to trigger one.
The test itself is still useful to diagnose or refute alleged memory
leaks.
This commit also move the test from JUnit 4 to Junit 5.
If run in parallel with other unit tests, especially onces that open
up a proxy, this test could fail, because another unit test actually
had an proxy running on the very address this unit test assumes to be
no proxy running.
We now use an IP address from RFC 5737's TEST-NET-1 address block,
which should never be available.
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.
