from o.jsmack.tcp.sm, as XEP-198 Stream Management is not an "XMPP over
TCP" exclusive feature. It could also be use together with the Websocket
binding of XMPP, so we may have a smack-streammangement in the
future. This change prepares for that by moving the SM code out of the
XMPP TCP package namespace.
if connect() was not previously called. Previously calling login() with
arguments would not check for the preconditions.
The check to throw needs to be performed in AbstractXMPPConnection
before every 'abstract login(Non)Anonymously()' call. That's the two
lines that check the preconditions are duplicated.
Also fix NPE in
XMPPTCPConnection.throwNotConnectedExceptionIfAppropriate() when
packetWrite is null (i.e. if the connection was never connected before).
(yeah, I know)
Sometimes "a friend" has setup an XMPP service which uses a self-signed
cert. While we can get a decent amount of security by using techniques
like e.g. the MemorizingTrustManager, there's still a pitfall. If the
service's TLS certificates contains no or the wrong service/hostname
information, Smack will throw an CertificateException. Therefore provide
an API call to disable hostname verification.
This is useful for cases where a result set is requested, as it's the
case in XEP-13 and XEP-313.
Also adds
XMPPConnection.createPacketCollector(PacketCollector.Configuration).
InterruptedExceptions should be treated as the users intention to
'cancel' the current thread's task. There is no such thing as a
spurious interrupt (not to be confused with "spurious wakeups").
after at most 12 hours.
Also set a keep alive time for the removeCallbacksService to 30 seconds
and add AbstractXMPPConnection.schedule(Runnable, long, TimeUnit).
Note that the logic determining the max resumption time has changed,
Math.min() is now used instead of Math.max(). This should match the real
life situation, e.g. if the server announced a max resumption time of 10
minutes and the client one of 5, then it should be assumed that the
connection/stream state is dropped by the parties after 5 minutes.
From XEP-198: Stream Management § 4. Acks:
"""
Note: There are two values of 'h' for any given stream: one maintained
by the client to keep track of stanzas it has handled from the server,
and one maintained by the server to keep track of stanzas it has handled
from the client. The client initializes its value to zero when it sends
<enable/> to the server, and the server initializes its value to zero
when it sends <enabled/> to the client (it is expected that the server
will respond immediately to <enable/> and set its counter to zero at
that time).
"""
Previously smack initialized both to 0 just before sending enabled. But
according to the note from XEP-198 the server's counter is initialized
by the server "when it sends <enabled/> to the client, so we need to set
clientHandledStanzasCount to 0 when we receive <enabled/>. Because the
server started counted right after he send <enabled/>.
Thanks to Kim "zash" Alvefur for pointing this out.
instead of calling just instantShutdown(). Now we will catch this
exception, call notifyConnectionError which also calls
instantShutdown() but also notifies the connection listeners of the
event.
Smack should never all instantShutdown() without notifying the
connection listeners.
- Don't abort if there is a NotConnectedExceptions, other listeners may
want to be informed of the ack nevertheless.
- Simply return if the id is null or empty.
Add shortcut: If stanzaAcknowledgedListeners is not empty, then we don't
need to check the stanzaIdAcknowledgedListeners.
Also fixes a bug, instead of
if (id != null && stanzaAcknowledgedListeners.contains(id)) {
it must be
if (id != null && stanzaIdAcknowledgedListeners.containsKey(id)) {
isAnonymous() is now a bit weakened since it also considers
allowNullorEmptyUsername.
SaslExternalMechanism of smack-sasl-provided now also doesn't throw an
UnsupportedOperationException.

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.
to ConnectionConfiguration.Builder().
And prepare SASL EXTERNAL for empty or null usernames.
Also clarify some parts regarding the user field.
Fixes SMACK-627
Move Forwarded into forward.packet and remove deprecated methods. Also
make fields final.
Improve ForwardedProvider:
- use INSTANCE of DelayInformationProvider
- use loop label
- don't throw exceptions in certain cases, instead log
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.
Use anonymous inner classes for packet listeners so that the
processPacket() method is not exposed as part of the Managers public
API.
And some small fixes.
It's important to know if the stream was resumed. authenticated() is the
ideal callback for Managers to reset their state (e.g. cached values of
the connection state). But if the stream was resumed, the cached values
don't have to be reset.
notably add a cache for the active and default privacy list to avoid
IQ get/response round-trips.
Also add a few methods to PrivacyListManager to get the privacy list
names. The already existing methods always returned the whole list
together with the name, which caused two round-trips.
Simplified some code.
Properly escape Privacy XML.
