Re: Undeploying an application, which is not deployed, throws NPE
Posted by Isuru Haththotuwa <is...@apache.org>.
AFAIU, we could check if such an application exists (with the given app
Id), and return/warn that there is no such app before calling
handleApplicationUndeployed() method. wdyt?

This should be a mistake. Should be in some other correct state. Or else
IMO we can even remove the context here since we are undeploying.

It seems logic is, that updating application to "created" status since the
application is not deployed anymore.
Solution should be adding a null check and stop the flow if application is
null as you suggested.

Re: Undeploying an application, which is not deployed, throws NPE
Posted by Rajkumar Rajaratnam <ra...@wso2.com>.
Yeah.
Can anyone recall the reason behind this logic (highlighted in red color)?
We can put a null check there. But I want to understand what we are doing
here. Why we need to create the application context in undeployApplication
API?
Thanks.

HI Raj,
I too experienced this while doing alpha testing. There is a jira I
reported too.

Re: Undeploying an application, which is not deployed, throws NPE
Posted by Rajkumar Rajaratnam <ra...@wso2.com>.
This is the undeployApplication API.
Why we are doing something in red here?
As application context is not there, it is throwing NPE.
@Override
public void undeployApplication(String applicationId) {
try {
if (log.isInfoEnabled()) {
log.info("Starting to undeploy application: [application-id] "
+ applicationId);
}
ApplicationBuilder.handleApplicationUndeployed(applicationId);
ApplicationContext applicationContext =
AutoscalerContext.getInstance().getApplicationContext(applicationId);
applicationContext.setStatus(ApplicationContext.STATUS_CREATED);
AutoscalerContext.getInstance().updateApplicationContext(applicationContext);
DeploymentPolicy deploymentPolicy =
PolicyManager.getInstance().getDeploymentPolicy(applicationId);
PolicyManager.getInstance().removeDeploymentPolicy(deploymentPolicy);
if (log.isInfoEnabled()) {
log.info("Application undeployed successfully: [application-id]
" + applicationId);
}
} catch (Exception e) {
String message = "Could not undeploy application: [application-id]
" + applicationId;
log.error(message, e);
throw new RuntimeException(message, e);
}
}
Thanks.
