RFC 6121 § 5.2.2:
"""
If an application receives a message with no 'type' attribute or the
application does not understand the value of the 'type' attribute
provided, it MUST consider the message to be of type "normal" (i.e.,
"normal" is the default).
"""
to avoid confusion between the IQ element 'iq' and the IQs child
element. ELEMENT defined in an IQ sublcass should contain the *child*
element.
Add element to StreamInitation and fix FileTransferManager which still
used a packet listener instead of an IQ request handler to handle
incoming stream initiation requests.
This also moves the logic to send error IQ replies from "when there is
no IQ provider registerd" to "when there is no IQ request handler
registered". Which has for example the advantage that IQ parsing no
longer asks for a connection instance.
This fixes e.g. IllegalArgumentException "'conflict' can not contain a
condition text", when receiving elements like
<stream:error>
<conflict xmlns='urn:ietf:params:xml:ns:xmpp-streams'></conflict>
<text xml:lang='' xmlns='urn:ietf:params:xml:ns:xmpp-streams'>
Replaced by new connection
</text>
</sream:error>
(ejabberd does this)
Introduce AbstractError, change 'Conditions' to enums. Because of
AbstractError, it was necessary that PlainStreamElement and
TopLevelStreamElement becomes an interface. Thus the implementation of
TopLevelStreamElement.toString() had to be removed.
This adds
- policy-violation
- unexpected-request
to XMPPError.Condition, and removes the
- payment-required
- remote-server-error
- unexpected-condition
- request-timeout
Conditions
The file transfer code does now no longer throw XMPPErrorExceptions, but
SmackExceptions.
Fixes SMACK-608. Makes it possible to resolves SMACK-386.
This is actually only part one, i.e. with this commit if the user adds a
PacketExtension to an IQ it will be included in IQ.toXml(). Which was
previously only the case if the IQ subclass explicitly included packet
extensions.
The second part of the change is to change the IQ provider, so that
packet extensions are automatically parsed.
Cases where PacketExtensions are used for Message and IQ are slightly
changed. The IQ sublcass now only has a field with this
PacketExtension (see for example
bytestreams.ibb.packet.DataPacketExtension).
Also changed hoxt API: Removed unnecessary indirection and made the
API more Smack idiomatic.
Remove the synchronized, as getExtensions() is properly synchronized and will
return a copy.
Return XmlStringBuilder instead of CharSequence to take advantage of
fast XmlStringBuilder.append(XmlStringBuilder).
Mark the method as final, as it should not be overwritten.
to keep the order in which the elements are added.
Some XEPs define a Schema using 'xs:sequence' (see for example XEP-60 §
17.1), so the order the PacketExtensions are added should be the same
they are transformed to a XML String.
Those where never correctly implemented and are not really used. If you
want to compare Packets, compare their toXML() result.
N.B. that we keep hashCode/equals for Message.(Subject|Body) because
those are correct and are in-use ('bodies' and 'subjects' are Sets in
Message).
allowing O(1) lookups for PacketExtensions
The one EntityCapsManagerTest becomes obsolete with this change, as
duplicate extension elements (RFC 6120 § 8.4) are now no longer possible
after the stanza has been parsed (they still may be received on the
wire, but only the last duplicate will be added).
