Michael Jumper created GUACAMOLE-629:
----------------------------------------
Summary: Stream protocol argument values
Key: GUACAMOLE-629
URL: https://issues.apache.org/jira/browse/GUACAMOLE-629
Project: Guacamole
Issue Type: Improvement
Components: guacamole-common-js, libguac
Reporter: Michael Jumper
The Guacamole protocol as designed currently imposes limitations on the
configuration of a connection:
# Connection configuration can be applied only during the initial protocol
handshake. If the user wishes to change aspects of the connection while the
connection is in progress, such as to alter the terminal appearance or provide
a username/password in response to a request from the remote desktop server,
this cannot be done.
# Connection parameters are inherently limited by the maximum length of an
instruction element and the overall maximum length of instructions. Providing
lengthy SSH keys for authentication, for example, is problematic
(GUACAMOLE-350).
With relatively minor changes to the Guacamole protocol, the above limitations
can be addressed. By sending connection parameters using streaming instructions
rather than as elements of a single, monolithic "connect" instruction,
parameter values can have unlimited length. By extending the use of that
parameter streaming instruction such that it can be used both during a
connection and during the handshake, protocol plugins can choose to allow
certain parameters to be set or updated while the connection is in progress.
