Event Index
===========

Slixmpp relies on events and event handlers to act on received data from
the server. Some of those events come from the very base of Slixmpp such
as :class:`~.BaseXMPP` or :class:`~.XMLStream`, while most of them are
emitted from plugins which add their own listeners.

There are often multiple events running for a single stanza, with
different levels of granularity, so code must take care of not
processing the same stanza twice.


.. glossary::
    :sorted:

    connected
        - **Data:** ``{}``
        - **Source:** :class:`~.XMLStream`

        Signal that a connection has been made with the XMPP server, but a session
        has not yet been established.

    connecting
        - **Data:** ``{}``
        - **Source:** :class:`~.XMLStream`

        Signal that a slixmpp will start to try establishing a connection.

    connection_failed
        - **Data:** ``str`` or ``OSerror``
        - **Source:** :class:`~.XMLStream`

        Signal that a connection attempt failed, either due to a lack of DNS
        records, or a network-level exception happened.

    ssl_cert
        - **Data:** ``str``
        - **Source:** :class:`~.XMLStream`

        Signal containing a PEM representation of the peer certificate when
        establishing a TLS connection. The certificate can be checked synchronously
        in this handler, and the attempt can be aborted if needed.

    tls_success
        - **Data:** None
        - **Source:** :class:`~.XMLStream`

        Signal following ``ssl_cert`` indicating that a TLS connection has been
        established and the XML stream will be proceeding.

    ssl_invalid_chain
        - **Data:** :py:class:`ssl.SSLError` the ssl exception
        - **Source:** :class:`~.XMLStream`

        Signal emitted when there is an SSL error when connecting. If not
        handled, slixmpp will disconnect rather than attempt connecting
        using the next method.

    stanza_not_sent
        - **Data:** :py:class:`~.stanza.rootstanza.RootStanza` or ``str``, the stanza slixmpp attempted to send
        - **Source:** :class:`~.XMLStream`

        Signal emitted when a stanza could not be sent because slixmpp is not
        connected (fully or at all) to the server. The stanza is queued for
        sending when the connection is established again.

    changed_status
        - **Data:** :py:class:`~.Presence`
        - **Source:** :py:class:`~.roster.item.RosterItem`

        Triggered when a presence stanza is received from a JID with a show type
        different than the last presence stanza from the same JID.

    changed_subscription
        - **Data:** :py:class:`~.Presence`
        - **Source:** :py:class:`~.BaseXMPP`

        Triggered whenever a presence stanza with a type of ``subscribe``,
        ``subscribed``, ``unsubscribe``, or ``unsubscribed`` is received.

        Note that if the values ``xmpp.auto_authorize`` and ``xmpp.auto_subscribe``
        are set to ``True`` or ``False``, and not ``None``, then  will
        either accept or reject all subscription requests before your event handlers
        are called. Set these values to ``None`` if you wish to make more complex
        subscription decisions.

Dedicated PubSub Events
=======================

The :class:`~.XEP_0060` plugin (and :class:`~.XEP_0163` plugin, which uses
