It was necessary to change saslFeatureReceived from SmackException to
XMPPException in order to return the StreamErrorException at this sync

tlsHandled sync point for SmackException (which just acts as a wrapper
for the various exception types that could occurn when establishing
TLS). The tlsHandled sync point is marked successful even if no TLS
was established in case none was required and/or if not supported by
the server.

Instead of extending SocketFactory, the proxy support classes now

Fixes SMACK-678.
A sequence of connect(), disconnect(), and connect() could cause the
connection to get disconnected again by the old reader thread, which was
blocking on disconnect because a closing stream tag was read. If the
second connect() was processed before the disconnect(), then the
connectin would get disconnected right after the second connect().
This showed up as a "strange" sequence of stanzas in the XMPP servers
log. Note that the stanza ID of the unavailable presence has a lower
number then the previous stanzas:

This is because the disconnect() of the first reader thread could
generate the unavailable presence, but was blocked afterwards when
entering the synchronized disconnect(Presence unavailablePresence).
SMACK-633.
Instead of allocating one big continuous memory block before "writing"
the XMPP stream element to the socket, write the single CharSequences of
LazyStringBuilder/XmlStringBuilder.
Also change Obserable writer to only notify the listeners after a
flush *or* if a certain limit has been reached since the last
notification. Otherwise the debugger would "print" every single XML part
as result of this change.

Smack now has a configuration builder method to set anonymous/external
authentication. This also removes a lot of duplicate code within
Smack.

Previously Smack would put messages in the unacknowledgedStanzas queue
after it received the 'enabled' element, when it should do so right
after sending the 'enable' stream element.
Imagine a session where '-->' denotes "received from server" and '<--'
"sent to server"
<-- enable
--> iq roster push set
--> presence some presence
<-- iq roster push result
--> enabled
then Smack would not add the iq roster push result stanza to the
unacknowledgedStanzas queue.
This fixes the issue by initializing the unacknowledgedStanzas queue
when the writer thread encounters a 'Enable' stream element.
The additional 'instanceof' invocation in the writer thread should not
be a big performance issue, since the existing "instanceof Stanza" check
should be the common case and the "instanceof Enable" is an exclusive
alternative to this case.
Instead of always bundling when the queue is empty, only bundle once the
queue has become empty and then only if it has been become empty again.
The previous algorithm would also bundle and defer the last element
found in the queue. This is not the case now.
in XMPPTCPConnection.
So that the hostname and not the IP is available to the SSLSocket and
the SSLSession, which handed over to HostnameVerifier. This leaves the
HostnameVerifier with the
- name of the XMPP service (first argument of verify(String, SSLSession)
- name of the used host (found in the SSLSession)
allowing more complex verification mechanisms performed by the
HostnameVerifier.

from o.jsmack.tcp.sm, as XEP-198 Stream Management is not an "XMPP over

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).
InterruptedExceptions should be treated as the users intention to

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

Also fixes a bug, instead of

it must be

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.
Differentiate between asynchronous and synchronous ones. Asynchronous
are the ones where the invocation order may not be the same as the order
in which the stanzas arrived.
Since it's no longer guaranteed that when a unit test calls
processPacket(stanza)
the stanza will be completely processed when the call returns, it was
necessary to extend the unit tests (mostly Roster and ChatManager) with
a packet listener that waits for his invocation. Since we now also use
LinkedHashMaps as Map for the packet listeners (SMACK-531, SMACK-424),
adding a packet listeners as last also means that it will be called as
last. We exploit this behavior change now in the unit tests.
Rename 'recvListeners' to 'syncRecvListeners' in AbstractXMPPConnection.

Since c81cd34561 we can report not
connected/authenticated when the client is disconnected but the stream
could be resumed. The previous behavior caused some confusion among
the users.
The 'break' statement in the END_DOCUMENT case should break the parsing
loop and not the switch/case within. Therefore we need to add a loop
label on break on that label.
Introducing a clean split between the constant connection configuration
parameters, which are now all in ConnectionConfiguration and the dynamic
connection state (e.g. hostAddresses) which are now in
AbstractXMPPConnection.
Also removed all arguments of login() since the username, password,

ConnectionConfiguration.
Also remove documentation/extensions/messageevents.md, as it's already

forcible close the socket.
sendListeners are now invoked *after* the packet has been put on the
wire.
Also sending listener exceptions are not catched and not only
NotConnectedExceptions. And a exception does not cause a 'break' but a
'continue' now. Log level is WARNING now.
this is the first stop towards fixing "SMACK-65: parsing should look for
depth", by providing the initial parsing depth to the provider. Some
methods (.e.g parseMessage) now use the depth as abort condition,
instead of a unclean String equals check.
parseIQ() and parseExtension() where both renamed to parse.
This also restricts the Exceptions thrown by the parse method, to just
XmlPullParserException, IOException and SmackException (not really a big
victory, but nevertheless a slight improvement).
StreamFeatureProvider is now gone, we simply use PacketExtensionProvider
for stream features.
so that APIs that need a fully connected but not yet authenticated
connection (e.g. AccountManager) can use the connection after connect()
returns.
Also move "connected = true" after saslFeatureReceived check, as if the
check would throw, the boolean would still be 'true' resulting in an
inconsistent state.

This commit marks an important milestone with the addition of the
smack-android subproject. Smack is now able to run native on Android
without requiring any modifications, which makes the aSmack build
environment obsolete.
It was necessary to redesign the code for SASL authentication to achieve
this. Smack now comes with smack-sasl-provided for SASL implementations
that do not rely on additional APIs like javax for platforms where those
APIs are not available like Android.
The idea is that xml-roundtrip should *never* be expected from a
XmlPullParser. So what we need is a method that parses the content of an
element without relying on getText() returning text if on START_TAG or
END_TAG. This is already done by PubSubs ItemProvider.
Also add PacketParserUtils.parseElement() which will return the current
element as String and use this method in PubSub's ItemProvider.
Move some duplicate code from XMPP(TCP|BOSH)Connection to
PacketParserUtils. Remove TestUtils as the method now part of Smack's
public API in PacketParserUtils.
Because of OSGi, no subproject of Smack (which is the same as a OSGi
bundle) must export a package that is already exported by another
subproject.
Therefore it was necessary to move the TCP and BOSH code into their own
packages: org.jivesoftware.smack.(tcp|bosh).
OSGi classloader restrictions also made it necessary to create a
Declarative Service for smack-extensions, smack-experimental and
smack-lagacy (i.e. smack subprojects which should be initialized), in
order to initialize them accordingly, as smack-core is, when used in a
OSGi environment, unable to load and initialize classes from other smack
bundles. OSGi's "Service Component Runtime" (SCR) will now take care of
running the initialization code of the particular Smack bundle by
activating its Declarative Service.
That is also the reason why most initialization related method now have an
additional classloader argument.
Note that due the refactoring, some ugly changes in XMPPTCPConnection
and its PacketReader and PacketWriter where necessary.

instead of using the old baseName=smack appendix=project.name approach,
we are now going convention over configuration and renaming the
subprojects directories to the proper name.
Having a prefix is actually very helpful, because the resulting
libraries will be named like the subproject. And a core-4.0.0-rc1.jar is
not as explicit about what it actually *is* as a
smack-core-4.0.0-rc1.jar.
