If we do not peek at the scheduled actions in the reactors
synchronized block, then there is a kind of lost-update problem. While
Ractor.schedule() will call wakeup() on the selector, a thread could
have already determined the value of selectWait, while being blocked
at the start of the synchronized reactor section. Once it is able to
enter the section, it will use an outdated selectWait value.
This leads to scheduled actions not being executed on time.
Thanks to Eng ChongMeng for reporting this and suggesting the fix.
Besides the way the transport handles the stream after SASL
<success/>, the SASL logic is independend from the underlying
transport (BOSH, TCP, …). Hence move it up into
AbstractXMPPConnection.
This also has the benefit that we can make some more methods private
or package-private.
Also introduce XmlStringBuilder.optTextChild(), which causes some
associated changes.
Thanks to PolFW, who writes:
A SASLErrorException is thrown before we have received the "<success
xmlns='urn:ietf:params:xml:ns:xmpp-sasl'/>". This is because
SASLAuthentication is keeping a reference to a "saslException" so to
clear that after a authentication failure we have to invoke again
connect on the xmpptcpconnection to initialize again the
saslAuthentication. But it doesn't solve the issue because an
AlreadyConnectedException is thrown before the initialisation of the
"this.saslAuthentication.init();"
Note that the user uses one time tokens for authentication.
and FileTestUtil in favor of commons-io. This is required because
Eclipse won't put src/test code into the classpath of src/main
code (even though gradle was configured with an according
dependency).
- Reduce the amount of types that are subtypes of NamedElement. See
javadoc of NamedElement for rationale.
- Work more with XmlEnvironment in XmlStringBuilder.
- Some minor changes to XmlStringBuilder API.
This patch makes it possible to change the stream-level language as part
of the connection configuration, to allow a properly implemented
entities to provide i18n'ed response messages. The Locale type is used
for this configuration, and the effective language string can be
obtained via `ConnectionConfiguration.getXmlLang()`.
This code does not cover XMPPBOSHConnection!
