We previously only looked in the registry for 'submit' type forms. But
also 'result' type forms may be send without field type
annotations. Same is true, but less likely, for 'form' type forms.
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.
Now that FormWriter, with its write() method, is gone, there is no
reason the FormReader method should still be named read(). Renaming to
getField() as this is what DataForm also uses.
`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.
The FaultTolerantNegotiator is the reason why Smack replies in a
non-standard way to file transfer requests: Smack puts two values in
the stream-method field, while the field is a list-single field,
i.e. a field which only allows one value.
Even if what Smack does is probably better, as it allows for a
fallback in case the bytestream transport fails, it is not standard
compliant. And, Jingle provide a proper fallback specification for
file transfers.
Fixes SMACK-561.
Those configurations where removed with version 1.13 (2010-07-12) of
XEP-0060.
This change is part of the effort to upgrade Smack's PubSub
implementation (SMACK-364).
