[jboss-jira] [JBoss JIRA] (WFCORE-3039) Capability requirement can be lost if two attributes on same resource reference the same capability
[

Jeff Mesnil commented on WFCORE-3039:
-------------------------------------
I quickly looked at the code related to this failure.
In org.jboss.as.controller.OperationContext#registerAdditionalCapabilityRequirement, the
method accepts an attribute parameter whose javadoc says "the name of the attribute
that triggered this requirement, or {@code null} if no single attribute was
responsible"
However in
org.jboss.as.controller.AbstractAddStepHandler#recordCapabilitiesAndRequirements, when we
record the requirements for the resource, we do:
1. add capability requirements for each attribute of the resource
2. get the context's resourceRegistration
3. for each requirements, we add capability requirements without specifying the attribute
that triggered the requirement[1]
It seems that we should properly tracked the attribute that was responsible of the
capability requirements in order to distinguish the "combined-providers"
capability coming from either the final-providers or initial-provides attribute.

where attributeName is null
Capability requirement can be lost if two attributes on same resource
reference the same capability

Key: WFCORE-3039
URL: https://issues.jboss.org/browse/WFCORE-3039
Project: WildFly Core
Issue Type: Bug
Components: Management
Reporter: Darran Lofthouse
Assignee: Radovan Netuka
With the following three commands the server becomes unable to boot due to a missing
dependency: -
{noformat}
/subsystem=elytron:write-attribute(name=initial-providers, value=combined-providers)
/subsystem=elytron:undefine-attribute(name=final-providers)
/subsystem=elytron/aggregate-providers=combined-providers:remove
{noformat}
If however I execute :reload after the first two commands, the final command will fail
correctly.
{noformat}
[standalone@localhost:9990 /]
/subsystem=elytron/aggregate-providers=combined-providers:remove
{
"outcome" => "failed",
"failure-description" => "WFLYCTL0367: Cannot remove capability
'org.wildfly.security.providers.combined-providers' as it is required by other
capabilities:
capability 'org.wildfly.security.elytron' requires it for attribute
'initial-providers' at address '/subsystem=elytron'",
"rolled-back" => true
}
{noformat}
I am only listing the 'Domain Management' component as I believe the security
example is just the reproducer.
