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.
Follow up on 7e4e3699a1
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.
Also add XHTMLExtension.from(Message) and change XHTMLManager.addBody()
signature so that it expects a XHTMLText (Modifications to the original
patch by Florian Schmaus).
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
- HeadersExtension.getHeaders() now returns a List instead of a
Collection
- Use XmlStringBuilder in Header and HeadersExtension toXML()
- Add HeadersProviderTest
- Use Smack formatting
Also remove duplicate parsing code regarding SHIM from HOXT
implementation.
- Change method modifiers keyword order to JLS
- Use attributecount when creating the HashMap
- Rename 'tag' to event'
- Use diamond operator
- Use Smack formatting style
