# The syntax for stream errors is as follows:
#
# <stream:error>
# <defined-condition xmlns='urn:ietf:params:xml:ns:xmpp-streams'/>
# <text xmlns='urn:ietf:params:xml:ns:xmpp-streams'>
# OPTIONAL descriptive text
# </text>
# [OPTIONAL application-specific condition element]
# </stream:error>
package provide streamerror 1.0
namespace eval streamerror {
# This maps Defined Conditions to clear text messages.
# draft-ietf-xmpp-core23; 4.7.3 Defined Conditions
# Applications use the error tag directly for the key into a message catalog.
variable msg
array set msg {
bad-format {The entity has sent XML that cannot be processed.}
bad-namespace-prefix {The entity has sent a namespace prefix that is unsupported, or has sent no namespace prefix on an element that requires such a prefix.}
conflict {The server is closing the active stream for this entity because a new stream has been initiated that conflicts with the existing stream.}
connection-timeout {The entity has not generated any traffic over the stream for some period of time.}
host-gone {The value of the 'to' attribute provided by the initiating entity in the stream header corresponds to a hostname that is no longer hosted by the server.}
host-unknown {The value of the 'to' attribute provided by the initiating entity in the stream header does not correspond to a hostname that is hosted by the server.}
improper-addressing {A stanza sent between two servers lacks a 'to' or 'from' attribute.}
internal-server-error {The server has experienced a misconfiguration or an otherwise-undefined internal error that prevents it from servicing the stream.}
invalid-from {The JID or hostname provided in a 'from' address does not match an authorized JID or validated domain negotiated between servers via SASL or dialback, or between a client and a server via authentication and resource binding.}
invalid-id {The stream ID or dialback ID is invalid or does not match an ID previously provided.}
invalid-namespace {The streams namespace name is something other than "http://etherx.jabber.org/streams" or the dialback namespace name is something other than "jabber:server:dialback".}
invalid-xml {The entity has sent invalid XML over the stream to a server that performs validation.}
not-authorized {The entity has attempted to send data before the stream has been authenticated, or otherwise is not authorized to perform an action related to stream negotiation; the receiving entity MUST NOT process the offending stanza before sending the stream error.}
policy-violation {The entity has violated some local service policy; the server MAY choose to specify the policy in the <text/> element or an application-specific condition element.}
remote-connection-failed {The server is unable to properly connect to a remote entity that is required for authentication or authorization.}
resource-constraint {The server lacks the system resources necessary to service the stream.}
restricted-xml {The entity has attempted to send restricted XML features such as a comment, processing instruction, DTD, entity reference, or unescaped character.}
see-other-host {The server will not provide service to the initiating entity but is redirecting traffic to another host; the server SHOULD specify the alternate hostname or IP address (which MUST be a valid domain identifier) as the XML character data of the <see-other-host/> element.}
system-shutdown {The server is being shut down and all active streams are being closed.}
undefined-condition {The error condition is not one of those defined by the other conditions in this list; this error condition SHOULD be used only in conjunction with an application-specific condition.}
unsupported-encoding {The initiating entity has encoded the stream in an encoding that is not supported by the server.}
unsupported-stanza-type {The initiating entity has sent a first-level child of the stream that is not supported by the server.}
unsupported-version {The value of the 'version' attribute provided by the initiating entity in the stream header specifies a version of XMPP that is not supported by the server.}
xml-not-well-formed {The initiating entity has sent XML that is not well-formed as defined by [XML].}
