---------------------------------
Summary: IPC interoperability problems with handshake
Key: AVRO-1177
URL: https://issues.apache.org/jira/browse/AVRO-1177
Project: Avro
Issue Type: Bug
Components: ruby
Affects Versions: 1.7.2
Reporter: Georg Franz
Attachments: avro_ruby_ipc.diff
I tried to get a simple echo service working using Java (client) to Ruby
(server).
The service should be called repeatedly in a loop. I tried several things, but
the best result I got was that it would work once, then raising this exception
on the ruby side:
{noformat}lib/ruby/gems/1.9.1/gems/avro-1.7.2/lib/avro/io.rb:46:in `byte!':
undefined method `unpack' for nil:NilClass (NoMethodError)

{noformat}
On investigation, I found out that the ruby Responder expects a handshake on
every request whereas the Java Requestor just sends a handshake the first time
around.
I quickly hacked up Ruby support for multiple calls on the same connection
similar to what the Java code does.
