----------------------------------------------
Summary: (7.0.z) COUNTER does not work with ForkChannel on an already
connected main channel
Key: JGRP-2191
URL: https://issues.jboss.org/browse/JGRP-2191
Project: JGroups
Issue Type: Bug
Reporter: Bartosz Spyrko-Śmietanko
Assignee: Bela Ban
Fix For: 4.0, 3.6.13
The following code doesn't work:
{code:java}
JChannel ch=new JChannel().connect("cluster");
ForkChannel fc=new ForkChannel(ch, "counter-stack", "counter-channel",
true,
ProtocolStack.Position.ABOVE, FRAG2.class,
new COUNTER());
CounterService counter_service=new CounterService(fc);
fc.connect("ignore");
Counter counter=counter_service.getOrCreateCounter("cntr", 0);
{code}
Method {{getOrCreateCounter()}} hangs as its coord is null because it didn't get a
view change. The issue is that COUNTER only processes view changes sent from below but not
from above. The former happens when the main channel is connected, the latter when
ForkChannel.connect() is called.
SOLUTION: add view change processing in down().
