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)) {
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.
Rename 'rosterInitialized' to 'loaded' in Roster.
Add Roster.isLoaded().
Reset 'loaded' to false in
Roster.setOfflinePresencesAndResetLoaded() (was setOfflinePresences()).
Fixes SMACK-583, SMACK-532, SMACK-424
on package layer instead of Declarative Service (DS) approach.
Restructuring and cleanup of initialization process to ensure that all
internal config files are found by the corresponding bundle
classloaders.
SMACK-343
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.
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,
resource and callback handler need now to be configured via
ConnectionConfiguration.
Also remove documentation/extensions/messageevents.md, as it's already
in documentation/legacy
- rename idStanzaAcknowledged to stanzaIdAcknowledged
- introduce smWasEnabledAtLeastOnce and throw
StreamManagementNotEnabledExceptions
- enable SM is SM resumption is enabled
Also remove unnecessary done() check in nextStreamElement() and remove
wrong comment in !instantShutdown branch. There is no mechanism to
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.
Otherwise this could result in

- Add SynchronizationPoint, ParserUtils

also remove faulty PongFilter from PingManager. It never matched any

any XMPP Ping namespace.
Fixes SMACK-597
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.
