David Lloyd created ELY-461:
-------------------------------
Summary: Enhancements to PermissionMapper, RoleMapper, RoleDecoder
Key: ELY-461
URL: https://issues.jboss.org/browse/ELY-461
Project: WildFly Elytron
Issue Type: Enhancement
Components: API / SPI, Permissions
Reporter: David Lloyd
Assignee: David Lloyd
Change RoleMapper, RoleDecoder, etc. to return new interface Roles which is iterable & has contains() method. Add chaining & etc. capabilities.
Change PermissionMapper to return new interface PermissionThing (come up with a name), which only has implies(Permission) & maybe default method checkPermission.
Change RoleDecoder to accept AuthorizationIdentity.
Change PermissionMapper to accept SecurityIdentity instead.
Add stuff to SecurityIdentity.

> Hi,
> I have ran into this a number of times and I am still working on the reproducer. I decided to raise this issue in case someone has seen something similar and/or I am on the wrong track and I'd rather know now before spending even more days on chasing this down.
> We had a DB outage 2 nights ago, and I have a timer task inserting 1 object into my rules every minute. The first time this happened with the DB outage, the result was:

[JBoss JIRA] (DROOLS-1093) Database Outage causes Session Persistence to break
by Artur Kronenberg (JIRA)
[ https://issues.jboss.org/browse/DROOLS-1093?page=com.atlassian.jira.plugi... ]
Artur Kronenberg commented on DROOLS-1093:
------------------------------------------
Finally I managed to reproduce it. As with the history of my reproducers, the code is a bit weird and there are manual instructions.
1. I am using a mysql database for persistence. (sadly the datasource must be a pooled datasource of the type I am using. I use the dropwizard factory to create it since this is as close to my setup as it gets and I did not manage to reproduce it any other way - using gradle should be fine to pull in that dep)
2. I create a persisted session the normal way
3. Insert an event that inserts 1k models into the session
4. create a timer task that inserts expiry facts that randomly match a model fact and retract them. (this task for some reason has to be set to at least 30 seconds (that is what i tried it with). If shorter, the effect is different ant the NPE does not appear)
5. now the fun part:
5.1. Use Starter to start the new application. (main method has to call create())
5.2. Once you see this message in the output, stop the database (mysql.server stop)
{code:java}
Expiry run. Sleep for a while. Rules: XXXX
Sleep
{code}
5.3. After you stopped the DB, wait for 30 seconds for the first exeption:
{code:java}

We have now created a broken session that can not be loaded anymore.
I apologise for the complicated nature of this, but it wasn't quite straight forward to reproduce this issue. I am still not certain what is happening here and how to handle it. Currently I have to recreate everything from scratch since there is no way to fix the session at that point anymore.
If you could advise me on how to work around this and or if I am somehow causing this issue myself, that would be wonderful :)
On IRC it was mentioned that when there is an SQL exception I should probably reload the session anyway. Is that correct?
Thanks,
Artur

[JBoss JIRA] (WFLY-6377) Composite Keys -- org.hibernate.property.access.spi.PropertyAccessException: Error accessing field
by Scott Marlow (JIRA)
[ https://issues.jboss.org/browse/WFLY-6377?page=com.atlassian.jira.plugin.... ]
Scott Marlow commented on WFLY-6377:
------------------------------------
I think that this was already fixed in Hibernate 5.0.9 (via HHH-10545 HHH-10546). Can you recreate with 5.0.9?

[JBoss JIRA] (WFLY-6382) Class loader leak due to Infinispan ExpirationManagerImpl
by Paul Ferraro (JIRA)
Paul Ferraro created WFLY-6382:
----------------------------------
Summary: Class loader leak due to Infinispan ExpirationManagerImpl
Key: WFLY-6382
URL: https://issues.jboss.org/browse/WFLY-6382
Project: WildFly
Issue Type: Bug
Components: Clustering, JPA / Hibernate
Affects Versions: 10.0.0.Final
Reporter: Paul Ferraro
Assignee: Paul Ferraro
h3. Scenario
Given a WAR containing a persistence unit with second level cache and query cache enabled, I'm consistently hitting a Metaspace OutOfMemoryError after redeploying the unchanged application a couple of times.
Analyzing the situation with Eclipse Memory Analyzer, I found one cause to be WFLY-6348, but even after applying that fix locally, I'm still having a Classloader leak which I can trace to a thread used by Infinispan referencing an obsolete web app classloader as context classloader.
Just to rule out that this might be related to WFLY-6283, WFLY-6285, I repeated my experiments with a local build of WildFly master (2f11a59aee0dbdd52b65c5c684eafa83c3f418da), with Hibernate locally upgraded to 5.0.9.
I'm still getting a classloader leak with that build.
h3. Analysis
{{org.infinispan.expiration.impl.ExpirationManagerImpl}} uses a {{LazyInitializingScheduledExecutorService}}. Due to lazy initialization, the {{ExecutorService}} and the underlying thread pool is not created until my web app is deployed. Thus, when the {{ExecutorService}} is created, the context class loader is set to the web app class loader, and this appears to propagate to the threads of the executor thread pool.
When the application is undeployed, {{ExpirationManagerImpl.stop()}} gets invoked to cancel any running expiration task. However, the {{ExecutorService}} is not shut down, the threads remain alive and still keep a reference to the now obsolete context classloader.
h3. Remarks
I'm not sure if this analysis is correct, at least I hope there's a clue for WildFly and Infinispan experts to identify the real cause.
By the way, it would be helpful if all threads created by Infinispan had meaningful names, rather than default names like {{pool-5-thread-1}}.

[JBoss JIRA] (WFLY-6377) Composite Keys -- org.hibernate.property.access.spi.PropertyAccessException: Error accessing field
by Akhbar Falafel (JIRA)
[ https://issues.jboss.org/browse/WFLY-6377?page=com.atlassian.jira.plugin.... ]
Akhbar Falafel commented on WFLY-6377:
--------------------------------------
[~smarlow] HHH-10618
To recreate the issue, I started the Wildfly server with no deployments via Eclipse. Once started, I deployed my .WAR file. At this point, my code _IS_ able to work as expected. Then, I performed a _clean_ (again via Eclipse) to redeploy my .WAR file. Once I do that, I get the exception noted in the report. I will post TRACE logs shortly.
