Where to add module definition in wildfly/build
by Cheng Fang
When I add a new module definition for a new sub-module into
wildfly/build directory, what is the right place?
wildfly/build/src/main/resources/modules/system/layers/base/org/wildfly/extension?
I see various modules using 3 different places:
wildfly/build/src/main/resources/modules/system/layers/base/org/wildfly/extension
wildfly/build/src/main/resources/modules/system/layers/base/org/wildfly
wildfly/build/src/main/resources/modules/system/layers/base/org/jboss/as
The hacking page (https://community.jboss.org/wiki/HackingOnWildFly)
says to use the jboss/as one, but I suspect it could be out of date.
Thanks,
Cheng

Layering docs?
by Heiko Braun
I am looking for some documentation on the PRD layering (EAP 6.1) is supposed to work. Can someone point me into the right direction?

Re: [wildfly-dev] duel between JPA use of ClassFileTransformer and CDI implicit/explicit Bean Manager (why can't we just get along)...

Lets do it this way, we can push this into JipiJapa so that only
Hibernate can do this initially. Other persistence providers can do the
same thing in JipiJapa if they also add the 2-phase support.

SDDS (Silly Deployment Detector Subsystem)
by Nicklas Karlsson
(I know there has been some discussion on the topic (old community AS7-dev
postings, IRC-chat with Tomaz Cerar etc)
Hanging around the forums, I've noticed that a frequent source of
hard-to-debug deployment problems and other non-linear-behavior is that
people often try to deploy archives with conflicting dependencies (various
EE APIs/impls already on the AS, JDBC drivers, maven plugins, you name it).
Would it be worthwhile to implement a deployment processor (disabled by
default) that would act as a helpful bouncer for the deployment archive? We
could have a simple isSane(Archive) interface or something and people could
write their own implementations (that would be picked up through the java
services system or listed explicitly in some module?). Default
implementation that come to mind is
* Blacklisted packages (using Tattletale to warn users if they are bundling
e.g. EE impls/APIs)
* Version limiter (using Tattletale to warn if deployment contains too old
version of lib, e.g. Spring)
* Unused libs (using Tattletale to warn if deployment contains unused jars)
* Server provided libs (using Tattletale and JBoss Modules) to show which
dependencies could be handled by a server module dependency)
I'm not sure JBoss Modules contains any "directory" for
which-modules-provides functionality but I guess the module root could be
scanned and the resources indexed or something. Performance would not be an
issue because it's still going to be faster that a user playing around with
dependencies for days.
Thoughts?

lots of tmp files from deployments
by Bill Burke
I'm running on Windows. Both AS7.1.1 and Wildfly . I've been starting
stopping the same jboss instances with the same deployments for weeks
now. There's about 100 deployments (TCK). I found that these
deployments are exploded in the standalone/tmp directory hundreds of
times so that I had like 300M+ files. I only noticed it because it
wreaked havoc on GIT and Intellij indexing.
Is this a known problem?

Maven central repo sync
by Martin Kouba
Hi All,
is there a plan to sync WildFly artifacts (e.g. arquillian container)
with maven central?
Thanks

JAXR backward compat
by Bartosz Baranowski
Hi
Im working on https://bugzilla.redhat.com/show_bug.cgi?id=964202 and there seems to be a problem.
Ive tried to reproduce this issue in upstream and it seems:
[Host Controller] 10:29:49,081 INFO [org.jboss.as.domain.controller.mgmt] (Remoting "port2:MANAGEMENT" task-10) JBAS010920: Server [Server:server-two] registered using connection [Channel ID 316dfe98 (inbound) of Remoting connection 248c1402 to /127.0.0.1:42158]
[Host Controller] 10:29:49,117 ERROR [org.jboss.as.controller.management-operation] (server-registration-threads - 1) JBAS014613: Operation ("describe") failed - address: ([
[Host Controller] ("profile" => "full"),
[Host Controller] ("subsystem" => "jaxr")
[Host Controller] ]) - failure description: "JBAS013452: Legacy extension 'org.jboss.as.jaxr' is not supported on servers running this version. The extension is only supported for use by hosts running a previous release in a mixed-version managed domain"
Support for this has been dropped.
Offending are two last commits: https://github.com/wildfly/wildfly/commits/master/jaxr/src/main/java/org/...
Shouldn't EAP 6 and 7 be backward compatible? If in this case answer is 'no' - is there any way to setup AS8 to reproduce this issue?
