[jira] Created: (FELIX-2031) Services should be registered
asynchronously
Services should be registered asynchronously
--------------------------------------------
Key: FELIX-2031
URL: https://issues.apache.org/jira/browse/FELIX-2031
Project: Felix
Issue Type: Bug
Components: Web Console
Affects Versions: webconsole-event-plugin-0.9.0
Reporter: Carsten Ziegeler
Assignee: Carsten Ziegeler
Fix For: webconsole-event-plugin-1.0.0
Some services are (un)registered during receival of a service event which is send synchronously. To avoid any problems these operations should be done asynchronously - when doing things synchronously I experienced a strange delay of exactly one minute.

[jira] Commented: (FELIX-2031) Services should be registered
asynchronously

Carsten Ziegeler commented on FELIX-2031:
-----------------------------------------
The registration is done in this way as the required classes (event package or config package) might not be available.
The registration is not delayed - the service listener gets an event that the event admin is available and then registers (delay) an event handler.
If the service listeners gets an event that the event admin is gone, the event handler is unregistered (again delayed).
So this shouldn't create a problem.

------------------------------------------
Just a thing to comment: While it is not a problem to delay acceptance of a newly registered service, delaying the release of an unregistering service might create issues. In the Rev. 905985 the window is actually half a second in which the service having gone might still be accessed...
What I do not understand is, why the Configuration Admin and Event Admin services are bound and why the ConfigurationListener and EventHandler services are only registered when the admin services exist ... I think the OptionalFeaturesHandler could just register the two services and be done.
