-----------------------------------
Summary: Ruby client examples incorrectly handles
'--connection-options' option
Key: QPID-4834
URL: https://issues.apache.org/jira/browse/QPID-4834
Project: Qpid
Issue Type: Bug
Components: Ruby Client
Affects Versions: 0.20
Reporter: Petr Matousek
Priority: Minor
The 'connection-options' option is incorrectly handled as a string in the
example clients, should be handled as a list.
# ruby spout.rb --connection-options "{reconnect:True}" "q;{create:always}"
2013-05-10 04:49:01 [Client] warning Exception received from broker:
not-found: not-found: Queue not found: {reconnect:True}
(/builddir/build/BUILD/qpid-0.22/cpp/src/qpid/broker/SessionAdapter.cpp:693)
[caused by 2 \x08:\x01]
./../lib/qpid_messaging/session.rb:63:in `createSender': Queue
{reconnect:True} does not exist (MessagingError)

The 'nil' in the option parser looked weird to me, so I did the
following change to make the option work:
# vim spout.rb
- opts.on(nil, "--connection-options VALUE",
+ opts.on("--connection-options VALUE",
Following change results in another error, the connection's
convert_options method expects list not a string:
# ruby spout.rb --connection-options "{reconnect:True}" "q;{create:always}"
./../lib/qpid_messaging/connection.rb:149:in `convert_options':
undefined method `each_pair' for "{reconnect:True}":String
(NoMethodError)
from ./../lib/qpid_messaging/connection.rb:67:in `initialize'
from spout.rb:103:in `new'
from spout.rb:103
I used the following code to fix the issue, which was sufficient for
my needs (there would be probably a better solution, I guess):
- options[:connection_options] = conopts
+ options[:connection_options] = {}
+ conopts = conopts.gsub /^\{(.*)\}$/, '\1'
+ conopts.split(",").each do |x|
+ key,val = x.split(':')
+ options[:connection_options][key]= val
