Keep getting directory not exists errors in build
by Bill Burke
I'm getting random "Home directory does not exist" errors when building
the core-model-tests. The thing is, its random. 4-5 times it fails,
1-5 times it succeeds.
So, I put a 10 millisecond delay after any mkdir() call in
TestModelControllerService and it seemed to solve the problem. Dont'
know if its my machine, Windblows or what. Maybe just a race condition
between JVM and the OS's file controller.

Confusion around deployment runtime-name
by Bartosz Baranowski
Hi guys.
Im trying to fix one of EAPs BZ and this led me into deep state of confusion.
Said BZ: https://bugzilla.redhat.com/show_bug.cgi?id=964446
Ive looked into CLI and this is what it offers:
[standalone@localhost:9990 /] deploy --help
SYNOPSIS
deploy ((file_path | --url=deployment_url)
[--script=script_name] [--name=deployment_name]
[--runtime-name=deployment_runtime_name]
...
file_path - filesystem path to the application to deploy.
If the deployment has to be added or replaced in the
repository, either the file_path or the --url argument
is required.
The path can be either absolute or relative to the current
directory.
--url - ...
--name - the unique name of the deployment. If the file path
argument is specified the name argument is optional with
the file name been the default value. If the file path
argument isn't specified then the command is supposed to
enable an already existing but disabled deployment, and in
this case the name argument is required.
--runtime-name - optional, the runtime name for the deployment.
A bit vague description of --runtime-name. --name gives a bit more info - it tells me that ${name} will be part of PathAddress in AS7 model.
I kept digging and found this bit in DMR file:
Name by which the deployment should be known within a server's runtime. This would be equivalent to the file name of a deployment file, and would form the basis for such things as default Java Enterprise Edition application and module names. This would typically be the same as 'name', but in some cases users may wish to have two deployments with the same 'runtime-name' (e.g. two versions of \"foo.war\") both available in the deployment content repository, in which case the deployments would need to have distinct 'name' values but would have the same 'runtime-name'."
Ok now to the point:
1. ${runtime-name} is used as 'root' of deployment. It becomes a part of service name in jboss MSC. However model name contains ${name}/archive name as root of PathAddress.
Is this correct? I've been told that this is wrong and the ${runtime-name} should be also part of PathAddress.
#1 is essentially a root of BZ. Operation seek service which contain ${name} as part of service name, while MSC has service which has the ${runtime-name}:
lookup value: jboss.deployment.subunit."jboss-as-ejb-in-ear-ear.ear"."jboss-as-ejb-in-ear-ejb.jar".component.GreeterEJB.START
actual msc service: jboss.deployment.subunit."nnn.ear"."jboss-as-ejb-in-ear-ejb.jar".component.GreeterEJB.START
2. From above description of runtime-name it seems I should be able to execute:
deploy --runtime-name=nnn.ear /x/archive-1.0.ear
deploy --runtime-name=nnn.ear /x/archive-1.1.ear
In fact I'm able to do that, but I've been told that this is wrong. Which is it?

Design of clustering subsystem for Wildfly
by Richard Achmatowicz
Hi
For part of the AS8 release, we are considering a new subsystem, called
cluster, which will provide a cluster-wide view of metrics associated
with applications deployed in a cluster. The idea for such a subsystem
has been around for a while (see WFLY-1236). The status is currently
experimental.
I have put together a document describing in overview what the purpose
of the subsystem is and what it might look iike. I am also in the
process of building a working version of the subsystem, as a kind of
proof of concept.
For anyone interested, please have a look at the design document:
https://community.jboss.org/wiki/DesignForClusteringSubsystemWFLY-1430
Any feedback is appreciated.
