That was helpful - I got farther - but not there yet.
I did the checkout of the umbrella with the command above:
hg clone http://hg.rabbitmq.com/rabbitmq-public-umbrella -r bug23568
but I did the 'make co' without any special parameters, so I assumed
that it did hg commands with respect to the bug23568 branch.
I built the metronome project as outlined on the Rabbit site and added
the rabbit_metronome-0.0.0.ez and amqp_client.ez files to the
rabbitmq-public-umbrella/rabbitmq-server/plugins directory, but when I
start it up I get:
linus:make run
RABBITMQ_NODE_IP_ADDRESS="" RABBITMQ_NODE_PORT="5679"
RABBITMQ_LOG_BASE="/tmp" RABBITMQ_MNESIA_DIR="/tmp/rabbitmq-bunny-mnesia"
RABBITMQ_PLUGINS_EXPAND_DIR="/tmp/rabbitmq-bunny-plugins-scratch" \
RABBITMQ_ALLOW_INPUT=true \
RABBITMQ_SERVER_START_ARGS="" \
./scripts/rabbitmq-server

(bunny at linus)1> Erlang has closed
{"Kernel pid
terminated",application_controller,"{application_start_failure,rabbit_metronome,{shutdown,{rabbit_metronome,start,[normal,[]]}}}"}
Crash dump was written to: erl_crash.dump
Kernel pid terminated (application_controller)
({application_start_failure,rabbit_metronome,{shutdown,{rabbit_metronome,start,[normal,[]]}}})
And as advertised it creates a big honkin' dump file.
I also had to create symbolic links so that the code would build. In my
rabbitmq-public-umbrella/rabbit_metronome directory I created:
amqp_client -> ../rabbitmq-erlang-client/dist/amqp_client
rabbit_common -> ../rabbitmq-erlang-client/dist/rabbit_common
The server works fine if run without adding plugins, but when I add them
it bombs, so I know the plugins are the problem (Right?).
I'm new to Erlang (interesting language), so all I did was cut and paste
the example Erlang code, so if that code is out of date then it would be a
problem.
Also: I changed the port to 5679 so it would not interfere with the official
installed RabbitMQ server on the same machine, and I set RABBITMQ_NODENAME
to 'bunny'.
Thanks,
- Jim
