[JBoss JIRA] (WFCORE-3327) Confusion about the recording of the org.wildfly.remoting.endpoint capability and the resource that configures it
by Brian Stansberry (JIRA)
[ https://issues.jboss.org/browse/WFCORE-3327?page=com.atlassian.jira.plugi... ]
Brian Stansberry commented on WFCORE-3327:
------------------------------------------
[~aloubyansky] AIUI the undertow and ejb3 cases are not the same. In undertow and ejb3 we have a parent resource providing a capability that depends on capabilities provided by children. But those resources are real resources, meaning they actually provide real runtime services.
The /subsystem=remoting/configuration=endpoint resource is not a real resource. It doesn't provide any runtime service. It's just a chunk of configuration used by the true resource, it's parent. It's an oddly implemented variant of that kind of configuration chunk, because the server itself adds it if the user doesn't, which is a pattern I don't recall elsewhere.
I've been looking at this and I'm starting to think that there's a 3) that's simpler than 2). Don't add a complex attribute to /subsystem=remoting. Instead, just add the /subsystem=remoting/configuration=endpoint attributes to it as simple attributes. No need to wrap them as fields in a complex attribute. As with 2) for API compatibility purposes only leave /subsystem=remoting/configuration=endpoint as an alias to those attributes. The /subsystem=remoting 'worker' attribute then is a simple attribute of the resource that provides the capability, the same as 99% of all capability reference attributes.
It seems like the only purpose /subsystem=remoting/configuration=endpoint served was as a kind of resource tree counterpart to the 'endpoint' child element in the xml that wraps these attributes. But there are plenty of ways to get that xml representation without adding a child resource.
3) is harder to implement than 2) for a mixed domain, but oh well.

> The org.wildfly.remoting.endpoint capability is reported by the /subsystem=remoting resource, but it is the /subsystem=remoting/configuration=endpoint that actually configures it. This is confusing for humans and difficult for tooling like the new provisioning tools.
> The configuration=endpoint child is essentially a singleton and internally it just provides configuration to its parent. Further, if the user does not configure this resource, a default one is added automatically. This child resources is really just a configuration chunk for its parent.
> In the end it is the parent resource that actually provides the capability, by installing a service. It reads its child resource to configure the capability.
> There are a couple possibilities here:
> 1) Simply move the declaration of the capability to the child resource. Per discussion with [~aloubyansky] is seems that solves the tool problem. It leaves the actual situation obscure though, because now a seemingly non-required child resource is the thing that provides a capability that actually will always be present.
> 2) Deprecate that child resource and add a complex attribute to the parent. The child resource continues to exist in the API for compatibility reasons, but simply modifies the attribute on the parent. The cap remains on the parent.
> Note that 2) may require some manipulation of how we handle undefined complex attributes; i.e. that when we resolve them, even if the root attribute is undefined, we need to resolve the fields, in case those have default values, with the resolved parent then including the default field values. That can be tricky though, e.g. in cases of things like the defaulted attribute having requires, or other fields in the complex attribute being required.
> This latter point is relevant because it would be a 'worker' field in a complex attribute that would actually declare the name of the needed io worker capability. That field would have a default value 'default'.
> Perhaps the declaration of the complex attribute itself (i.e. ObjectTypeAttributeDefinition) would need to indicate how things should be handled. That could just be the complex attribute itself has a default value, {"worker"=>"default"}. Or it could be a flag that enables looking at the fields for defaults if the top level attribute is undefined. Or maybe investigation will show this isn't a problem at all.

> I have been trying to reduce the deployment of a WAR application.
> One of the greate bottlenecks on the deployment is the cost of getting the first EntityManager instance of eclipselink.
> To try to reduce cost of startup I found myself forced to during @Startup fire a CDI event observed by an @Asynchronous ejb whose only task is to do a dummy entityManager.flush().
> The results I had for the execution time of this observer could go as high as 13 seconds.
> On top of that, I had already noticed while writting an arquillian system test for eclipselink on:
> https://issues.jboss.org/browse/WFLY-8954
> that the cost of starting up elcipselink under wildfly was much much higher than that of Hibernate and OpenJPA.
> With this introduction done let us go to the facts, and they are quite ridiculous.
> I have sampled the deployment of an application from begging to end with a sampling script that took a thread dump every second to analyse where the app is spending deployment time generically.
> Eventually, I reached the eclipselink deployment.
> And I had entries on the log such as:
> DatabaseEntityManagerStarter] - <- StartupDatabaseEntityManagerStarter.observeApplicationReadyLoadEntityManagerEvent {5948 ms} <EJB aync-ejb-thread-pool - 1>
> While sampling why this was happening I got more than 7 straight thread dump samples (more than 7 seconds) where the following stack trace was present:

> According to syslog specification[1] {{app-name}} cannot contain space character (" "). However, the default value in WildFly Core 3.0.0.Alpha3 is {{WildFly Core}}. This results in the syslog server is not able to capture Process ID from which the message was sent.
> E.g. following piece of information is captured {{WildFly[Core] (...)}} instead of {{WildFlyCore[795]}}
> Suggestions for improvement:
> Change default value {{WildFly Core}} to one without space character.
> Also please consider addition of check whether {{app-name}} contains space character.

> I have been trying to reduce the deployment of a WAR application.
> One of the greate bottlenecks on the deployment is the cost of getting the first EntityManager instance of eclipselink.
> To try to reduce cost of startup I found myself forced to during @Startup fire a CDI event observed by an @Asynchronous ejb whose only task is to do a dummy entityManager.flush().
> The results I had for the execution time of this observer could go as high as 13 seconds.
> On top of that, I had already noticed while writting an arquillian system test for eclipselink on:

> With this introduction done let us go to the facts, and they are quite ridiculous.
> I have sampled the deployment of an application from begging to end with a sampling script that took a thread dump every second to analyse where the app is spending deployment time generically.
> Eventually, I reached the eclipselink deployment.
> And I had entries on the log such as:
> DatabaseEntityManagerStarter] - <- StartupDatabaseEntityManagerStarter.observeApplicationReadyLoadEntityManagerEvent {5948 ms} <EJB aync-ejb-thread-pool - 1>
> While sampling why this was happening I got more than 7 straight thread dump samples (more than 7 seconds) where the following stack trace was present:

[JBoss JIRA] (WFLY-9408) Wildfly 10 - The cost of creating the first eclipselink EntityManager during deployment is extremelly high due to MBeanServer.getMbeanCount() cost
by Brian Stansberry (JIRA)
[ https://issues.jboss.org/browse/WFLY-9408?page=com.atlassian.jira.plugin.... ]
Brian Stansberry commented on WFLY-9408:
----------------------------------------
[~smarlow] My branch linked above isn't quite right either, as it is still using logging calls from the superclass. Those need to go since every time we upgrade eclipse link we have no idea whether those message codes / related params are correct.
So either the logging should be dropped altogether or the JPA subsystem will need to provide log messages.

> Wildfly 10 - The cost of creating the first eclipselink EntityManager during deployment is extremelly high due to MBeanServer.getMbeanCount() cost
> --------------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: WFLY-9408
> URL: https://issues.jboss.org/browse/WFLY-9408
> Project: WildFly
> Issue Type: Bug
> Components: JPA / Hibernate
> Affects Versions: 10.1.0.Final
> Reporter: Nuno Godinho de Matos
> Assignee: Scott Marlow
> Fix For: 11.0.0.Final
>
>
> I have been trying to reduce the deployment of a WAR application.
> One of the greate bottlenecks on the deployment is the cost of getting the first EntityManager instance of eclipselink.
> To try to reduce cost of startup I found myself forced to during @Startup fire a CDI event observed by an @Asynchronous ejb whose only task is to do a dummy entityManager.flush().
> The results I had for the execution time of this observer could go as high as 13 seconds.
> On top of that, I had already noticed while writting an arquillian system test for eclipselink on:
> https://issues.jboss.org/browse/WFLY-8954
> that the cost of starting up elcipselink under wildfly was much much higher than that of Hibernate and OpenJPA.
> With this introduction done let us go to the facts, and they are quite ridiculous.
> I have sampled the deployment of an application from begging to end with a sampling script that took a thread dump every second to analyse where the app is spending deployment time generically.
> Eventually, I reached the eclipselink deployment.
> And I had entries on the log such as:
> DatabaseEntityManagerStarter] - <- StartupDatabaseEntityManagerStarter.observeApplicationReadyLoadEntityManagerEvent {5948 ms} <EJB aync-ejb-thread-pool - 1>
> While sampling why this was happening I got more than 7 straight thread dump samples (more than 7 seconds) where the following stack trace was present:

> Is the problem that the API should cost ms and it literally takes several seconds to calculate - and the problem is the cost of the API under wildfly.
> Or is it that eclipselink should never have written such a log statement on the first place?
> To address the issue, I have hacked up my local:
> org.jipijapa.eclipselink.WildFlyServerPlatform
> In this class, I have override the getMeabServer API from the base class.
> I Have created a hacked constant:
> {panel}
> /**
> * During deployment, when the first entity manager is created, the
> * application deployment becomes extremelty slow due to the
> * MbeanServer.getbeanCount() access done by eclipselink. This access is on
> * top of all things done only for logging purposes. We completely kill the
> * call to the api.
> */
> private static final int MBEAN_SERVER_COUNT_DUMMY_VALUE = -999;
> {panel}
> And finally I added an overriden method:
> {panel}
> @Override
> public MBeanServer getMBeanServer() {
> /**
> * This function will attempt to get the MBeanServer via the
> * findMBeanServer spec call. 1) If the return list is null we attempt

> * more than one we get the lowest indexed MBeanServer that does not on
> * a null default domain. 3) 333336: we need to wrap JMX calls in
