Kabir Khan created WFLY-1636:
--------------------------------
Summary: Children coming from a
ManagementResourceRegistration.registerOverrideModel() override incorrectly appear as
attributes in read-resource-description
Key: WFLY-1636
URL: https://issues.jboss.org/browse/WFLY-1636
Project: WildFly
Issue Type: Bug
Components: Domain Management
Affects Versions: 8.0.0.Alpha2
Reporter: Kabir Khan
Assignee: Kabir Khan
Fix For: 8.0.0.Alpha3
The problem is in OverrideDescriptionCombiner adding the overridden children to the
attributes rather than to the children. For background, this was my initial mail on the
subject.
-------
I found this when trying to read the role based access control settings for the whole of
WIldFly. I have worked around this with a hack on my
https://github.com/kabir/wildfly/commits/rbac-play branch, which is called "Temp
commit, work around problems in /subsystem=datasources/data-source=* definition of
statistics". The underlying problem seems to be that there is a problem with the
resource definition for this attribute/child type. Apart from this there are no other
problems when running with standalone-full-ha.xml.
The 'statistics' appears as an attribute when doing a read-resource-description
[standalone@localhost:9990 /]
/subsystem=datasources/data-source=ExampleDS:read-resource-description
{
"outcome" => "success",
"result" => {
"description" => "A JDBC data-source configuration",
"attributes" => {
"share-prepared-statements" => {
"type" => BOOLEAN,
"description" => "Whether to share prepared statements,
i.e. whether asking for same statement twice without closing uses the same underlying
prepared statement",
"expressions-allowed" => true,
"nillable" => true,
"default" => false,
"access-type" => "read-write",
"storage" => "configuration",
"restart-required" => "no-services"
},
-- SNIP
"statistics" => {
"description" => "Runtime statistics provided by the
resource adapter.",
"access-type" => "read-only",
"storage" => "configuration"
}
},
"operations" => undefined,
"children" => {"connection-properties" => {
"description" => "The connection-properties element allows
you to pass in arbitrary connection properties to the Driver.connect(url, props)
method",
"model-description" => undefined
}}
}
}
However, it does not appears as a child but not as an attribute:
[standalone@localhost:9990 /]
/subsystem=datasources/data-source=ExampleDS:read-children-names(child-type=statistics)
{
"outcome" => "success",
"result" => [
"jdbc",
"pool"
]
}[standalone@localhost:9990 /]
/subsystem=datasources/data-source=ExampleDS:read-attribute(name=statistics)
{
"outcome" => "failed",
"failure-description" => "JBAS014640: 'statistics' is a
registered child of resource ([
(\"subsystem\" => \"datasources\"),
(\"data-source\" => \"ExampleDS\")
])",
"rolled-back" => true
}
In read-resource it appears as a child:
[standalone@localhost:9990 /]
/subsystem=datasources/data-source=ExampleDS:read-resource(recursive=true,
include-runtime=true)
{
"outcome" => "success",
"result" => {
---- SNIP ----
"statistics" => {
"jdbc" => {
"PreparedStatementCacheAccessCount" => "0",
"PreparedStatementCacheAddCount" => "0",
"PreparedStatementCacheCurrentSize" => "0",
"PreparedStatementCacheDeleteCount" => "0",
"PreparedStatementCacheHitCount" => "0",
"PreparedStatementCacheMissCount" => "0"
},
"pool" => {
"ActiveCount" => "0",
"AvailableCount" => "20",
"AverageBlockingTime" => "0",
"AverageCreationTime" => "0",
"CreatedCount" => "0",
"DestroyedCount" => "0",

"MaxWaitTime" => "0",
"TimedOut" => "0",
"TotalBlockingTime" => "0",
"TotalCreationTime" => "0"
}
}
}
}
[standalone@localhost:9990 /]
/subsystem=datasources/data-source=ExampleDS/statistics=jdbc:read-resource(include-runtime=true)
{
"outcome" => "success",
"result" => {
"PreparedStatementCacheAccessCount" => "0",
"PreparedStatementCacheAddCount" => "0",
"PreparedStatementCacheCurrentSize" => "0",
"PreparedStatementCacheDeleteCount" => "0",
"PreparedStatementCacheHitCount" => "0",
"PreparedStatementCacheMissCount" => "0"
}
}
