POE::Component::Jabber::XMPP (3pm)

This is a Protocol implementation for the specifics in the \s-1XMPP\s0 protocol during connection initialization.

\s-1PCJ::XMPP\s0 provides all the mechanisms to negotiate \s-1TLS\s0, \s-1SASL\s0, resource binding, and session negotiation that \s-1PCJ\s0 needs to successfully establish an \s-1XMPP\s0 connection. In essence, it implements \s-1XMPP\s0 Core and a smidgeon of \s-1XMPP\s0 \s-1IM\s0.

Please see PCJ::Protocol for what methods this class supports.

Listed are the exported events that make their way into the \s-1PCJ\s0 session:

set_auth

This handles the initial \s-1SASL\s0 authentication portion of the \s-1XMPP\s0 connection.

init_input_handler

This is our entry point. This is what \s-1PCJ\s0 uses to deliver events to us.

build_tls_wheel

If \s-1TLS\s0 is required by the server, this is where that negotiation process happens.

challenge_response

This handles the subsequent \s-1SASL\s0 authentication steps.

binding

This handles the resource binding

session_establish

This handles session binding.

Currently, only \s-1DIGEST-MD5\s0 and \s-1PLAIN\s0 \s-1SASL\s0 mechanisms are supported. Server implementations are free to include more strigent mechanisms, but these are the bare minimum required. (And \s-1PLAIN\s0 isn't /really/ allowed by the spec, but it is included because it was a requested feature)

The underlying backend has changed this release to now use a new Node implementation based on XML::LibXML::Element. Please see POE::Filter::XML::Node documentation for the relevant \s-1API\s0 changes.
