--------------------------------------
Summary: "uuid" property of Guacamole.ChainedTunnel may not be
initialized
Key: GUACAMOLE-1562
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1562
Project: Guacamole
Issue Type: Bug
Components: guacamole-common-js
Reporter: Mike Jumper
Depending on timing, the {{commit_tunnel()}} function of
{{Guacamole.ChainedTunnel}} may be invoked before the tunnel UUID is received.
If this occurs, the {{onuuid}} handler will be correctly invoked, but only the
{{uuid}} property of the underlying tunnel will be updated, leaving the
{{uuid}} property of the {{Guacamole.ChainedTunnel}} as {{null}}.
Additionally, if the tunnel-internal "ping" instruction specific to the
WebSocket tunnel is sent and handled prior to receiving the UUID, the server
response to that ping may be incorrectly interpreted as the UUID, causing
similar trouble.
For things like out-of-band file uploads to work correctly, the tunnel UUID
needs to always be correctly set.
