Tomer Gabel updated GUACAMOLE-1048:
-----------------------------------
    Summary: Support server control commands during handshake  (was: Expect and interpret error commands on handshake)

> Support server control commands during handshake
> ------------------------------------------------
>
>                 Key: GUACAMOLE-1048
>                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-1048
>             Project: Guacamole
>          Issue Type: Improvement
>          Components: guacamole-common
>            Reporter: Tomer Gabel
>            Priority: Minor
>
> The current implementation of client handshake in {{ConfiguredGuacamoleSocket}} doesn't handle the case where a server sends an error command mid-handshake, which is allowed by the protocol. This hampers error handling/reporting in some cases; for instance, when an invalid connection ID is specified by the {{select}} command, a resulting {{error}} would be misinterpreted by the client as an unexpected opcode.
> Please expect a pull request aimed at improving this situation soon; incidentally, the scenario described above is hypothetical, guacd currently drops the connection instead of sending an error command. This is handled separately in GUACAMOLE-1047.
