Michael Martell updated GEODE-8592:
-----------------------------------
Description:
As reported on StackOverflow
([https://stackoverflow.com/questions/64045931/repeated-ui-calls-to-geode-native-client-attributesmutator-setcachelistener)],
this looks like a bug with AttributesMutator when setting multiple
CacheListeners.
Direct from SO:
If I have a button on a UI that registers a listener, sync not async, and click
it several times, then repeatedly setting listeners on a region hangs:
A {{Cache c}} is already initialized. This is using the C# Geode Native Client.
{code:C#}
IRegion<string, Object> d = c.GetRegion<string, Object>("deal");
try
{ Logs.Trace("Registering key"); d.GetSubscriptionService().RegisterKeys(s);
d.AttributesMutator.SetCacheListener(new LDeal<string, Object>(c, AddDeal)); }
catch (Exception ex)
{ new ApplicationException("Can't register key: " + clOrdId, ex); }
}}
{code:C#}
Is this an optimal way to set a listener on a region? If it's going to hang how
can I have a timeout so that setting a listener is better managed?
UPDATE: using {{async}} / {{await}} appears to resolve this issue, so that the
{{SetCacheListener}} becomes
{code:java}
{{await Task.Run(() => d.AttributesMutator.SetCacheListener(new LDeal<string,
Object>(c, AddDeal)));}}
{{}}
{code:java}
{code}
