------------------------------------------
Summary: Expected call of configuration listeners for testing
Key: IGNITE-15823
URL: https://issues.apache.org/jira/browse/IGNITE-15823
Project: Ignite
Issue Type: Improvement
Reporter: Vladislav Pyatkov
In the same test cases, need to invoke a listener when the component state
changed (we have to have a guaranty that the listener doesn't call before).
For example, we have a closing procedure for _TableManager _ which can change a
component state in arbitrary time:
{code}
@Override public void stop() {
if (!stopGuard.compareAndSet(false, true))
return;
busyLock.block();
...
}
{code}
Depend on the _busyLock_ if holding or not, the behavior of configuration
listener changed:
{code}
tablesCfg.tables().
listenElements(new ConfigurationNamedListListener<TableView>() {
@Override
public @NotNull CompletableFuture<?> onCreate(@NotNull
ConfigurationNotificationEvent<TableView> ctx) {
if (!busyLock.enterBusy()) {
String tblName = ctx.newValue().name();
IgniteUuid tblId =
IgniteUuid.fromString(((ExtendedTableView)ctx.newValue()).id());
fireEvent(TableEvent.CREATE,
new TableEventParameters(tblId, tblName),
new NodeStoppingException());
return CompletableFuture.completedFuture(new
NodeStoppingException());
}
...
}
}
{code}
We need to check both cases (when the lock hold or not) in tests.
By the reason, we should implement specific API which allow invoking
configuration listeners when it is expected (state guaranteed).
