[rabbitmq-discuss] FW: Re: Erlang RabbitMQ Client hanshake problem on "State = Driver:handshake(InitialState), "

Tue Jun 9 18:42:16 BST 2009

Hi Matthias,

I have tried to do what you asked for in order for you to understand the
problem better, forgive me if I misinterpreted one or two things, just let
me know and I will try again ;-)

I really appreciate the help, thank you.

1) a directory listing of %ERLANG_HOME%\erl5.7.1\lib 

      You can see the Rabbit* folders below...

cid:image001.png at 01C9E936.39031960

cid:image002.png at 01C9E936.39031960

cid:image003.png at 01C9E936.39031960

2) a deep directory listing for all rabbitmq* directories in the above.

                Not sure how you wanted this represented?

cid:image004.png at 01C9E936.39031960

Just for interest this is the version etc of the Server....

cid:image005.png at 01C9E936.E23BB780

Here is the client.....latest version....

cid:image006.png at 01C9E936.E23BB780

3) the location of the erlang client directory, and a deep directory listing
thereof

cid:image007.png at 01C9E936.E23BB780

Here are my environment variables, not sure if you wanted to see them...

cid:image010.png at 01C9E937.54F671C0

4) the exact command line used for invoking the erlang client, including the
dir it is run from

NOTE: I *assume* that I don't need to add anything to the load path because
the server + client are in the Erlang LIB folder.....

Also, you can see it HANGING again.....

cid:image008.png at 01C9E938.2264EDD0

And just to see the LOG again from this evening...

=INFO REPORT==== 9-Jun-2009::19:13:10 ===

5) the output of [P || P <- code:get_path(), string:str(P, "rabbit") =/= 0].
when run inside the Erlang client's shell.

6) the output of  [code:which(M) || M <- [lib_amqp, rabbit_framing_channel,
rabbit]]. when run inside the Erlang client's shell.

cid:image011.png at 01C9E938.2264EDD0

7) the sequence of erlang function calls used in the test

For this is am just calling the "lifecycle_test" function in the
"network_client_test.erl" script in the TESTS folder of the client code.....

-module(network_client_test).

-export([test_coverage/0]).

-include_lib("eunit/include/eunit.hrl").

basic_get_test() ->

    test_util:basic_get_test(new_connection()).

    test_util:lifecycle_test(new_connection()).

queue_unbind_test() ->

    test_util:queue_unbind_test(new_connection()).

If you have the server in the above dir, as per the installation

instructions, then the client code should find the server libraries

without needing to modify the load path.

In order to diagnose this further, please send me

1) a directory listing of %ERLANG_HOME%\erl5.7.1\lib

2) a deep directory listing for all rabbitmq* directories in the above.

3) the location of the erlang client directory, and a deep directory

listing thereof

4) the exact command line used for invoking the erlang client, including

the dir it is run from

5) the output of [P || P <- code:get_path(), string:str(P, "rabbit") =/=

0]. when run inside the Erlang client's shell.

6) the output of  [code:which(M) || M <- [lib_amqp,

rabbit_framing_channel, rabbit]]. when run inside the Erlang client's shell.

7) the sequence of erlang function calls used in the test

Are you still getting {undef, [{rabbit_framing_channel,start_link,...}]}

error in the client? If so then the above is likely a consequence of that.

Some knowledge of Erlang when using the Erlang client is highly

recommended ;)

Matthias.
