qpid-conf and AMQP version
Hi,
I installed C++ broker 1.37 and configured:
protocols=amqp1.0
but qpid-config complains:
# qpid-config exchanges
Failed: VersionError: client: 0-10, server: 0-0
I also tried with
protocols=amqp1.0,amqp0-10
but same result, there is no fallback?
It works only when protocols are not specified. Would someone shed some light on this?
Kind regards, Jan

The qpid-config tool unfortunately only speaks AMQP 0-10 at present. If
you set AMQP 1.0 to be the only protocol, it can't connect.
To specify multiple protocols, use separate protocol options. E.g. on
command line do:
--protocol amqp1.0 --protocols amqp0-10
and in a config file do:
protocols=amqp1.0
protocols=amqp0-10
(Not the most intuitive configuration, I accept.)
Note that these are the only two supported options, so enabling them
both is what you get by default anyway.
The c++ client has its own option, default-protocols, and there the
ordering matters (and it is a comma separated list), as it dictates the
order in which the protocols are tried. The server waits for the client
to indicate the protocol it is using then responds.
