XMPP's <message> stanzas are a "push" mechanism to send information
to other XMPP entities without requiring a response.
Chat clients will typically use <message> stanzas that have a type
of either "chat" or "groupchat".
When handling a message event, be sure to check if the message is
an error response.
Example <message> stanzas:
<message to="user1@example.com" from="user2@example.com">
<body>Hi!</body>
</message>
<message type="groupchat" to="room@conference.example.com">
<body>Hi everyone!</body>
</message>
Stanza Interface:
body -- The main contents of the message.
subject -- An optional description of the message's contents.
mucroom -- (Read-only) The name of the MUC room that sent the message.
mucnick -- (Read-only) The MUC nickname of message's sender.
Attributes:
types -- May be one of: normal, chat, headline, groupchat, or error.
Methods:
Underscore names by default. Stanza objects now accept the use of underscored names. The CamelCase versions are still available for backwards compatibility, but are discouraged. The property stanza.values now maps to the old getStanzaValues and setStanzaValues, in addition to _set_stanza_values and _get_stanza_values.
2010-10-18 01:38:22 +00:00
setup -- Overrides StanzaBase.setup.
chat -- Set the message type to 'chat'.
normal -- Set the message type to 'normal'.
reply -- Overrides StanzaBase.reply
get_type -- Overrides StanzaBase interface
get_mucroom -- Return the name of the MUC room of the message.
set_mucroom -- Dummy method to prevent assignment.
del_mucroom -- Dummy method to prevent deletion.
get_mucnick -- Return the MUC nickname of the message's sender.
set_mucnick -- Dummy method to prevent assignment.
del_mucnick -- Dummy method to prevent deletion.

Fix stanza clobbering when replying to errors. If a stanza handler raised an exception, the exception was processed and replied by the modified stanza, not a stanza with the original content. A copy is now made before handler processing, and if an exception occurs it is the copy that processes the exception using the original content.
