Brian Stansberry commented on WFCORE-3039:
------------------------------------------
This problem isn't about reload; the reload just fixes the problem.
The problem is that both initial-providers and final-providers are attributes on the same
resource referencing the same "combined-providers" capability. The reproducer
executes the "undefine-attribute" last, and that has the effect of removing the
requirement, even though the initial-providers value means the requirement is still
needed.
There was some logic early on related to including attribute names as part of the
requirement registration point data, but it has atrophied due to lack of any apparent good
use case so I don't know if it can be cleanly resurrected to help handle this.
Simply switching the order of the undefine-attribute and write-attribute calls should
prevent the problem.
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: Domain Management
Reporter: Darran Lofthouse
Assignee: Brian Stansberry
Priority: Critical
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.
