Paul Ferraro commented on WFCORE-3977:
--------------------------------------
[~brian.stansberry] No, the SocketBinding will be UP when the TransportConfiguration is
UP. That's not the issue. The issue is that our protocol configuration objects
extract the address/port from the socket binding. When sockets are eventually created,
they are done so without any knowledge of the socket-binding from which the address/port
was extracted.
So really, the fundamental issue is that our JGroups SocketFactory creates sockets via the
"unnamed" variants of the SocketBindingManager. Since SocketBinding.isBound()
relies on being able to lookup a socket binding in the manager by name, it will always
return false for sockets created by JGroups.
It makes me wonder how many subsystem are actually doing this correctly. How many
subsystems are actually creating sockets using the SocketBinding.createSocket(...) methods
or using the named variants of the SocketBindingManager?
That said, JGroups SocketFactory _does_ use the concept of named sockets - however, its
uses its own naming convention for the socket names. Thus we need to construct the
SocketFactory with a Map<String, String> of JGroups socket names ->
socket-binding names. That way, the corresponding SocketBindingManager methods are called
with the correct socket-binding names.
So, in the end, this turns out to be a long standing JGroups subsystem bug. :)
Changing multicast address in socket binding does not trigger server
to set reload-required

Key: WFCORE-3977
URL:
https://issues.jboss.org/browse/WFCORE-3977
Project: WildFly Core
Issue Type: Bug
Components: Management
Affects Versions: 6.0.0.Alpha3
Reporter: Richard Achmatowicz
Assignee: Jeff Mesnil
Found this by accident when debugging a clustering test case.
If I start a server with profile standalone-full-ha and then modify the multicast address
of a clustering related socket-binding, in this case, jgroups-mping, the server is not put
into state reload-required.
This causes a lot of problems in the testsuite which depends on configuring servers after
startup and then restarting if necessary to pull in the changes.
