Fixed In Version:	rhevm-sdk-java-3.4.0.1-0.1.el6_5
Doc Type:	Bug Fix
Doc Text:	Previously, methods in the Java SDK that accept header or URL arguments would fail under certain conditions. This was caused by the logic in those methods, which would add those arguments to requests even when the values of the arguments were null. Now, this logic has been revised so that arguments with null values are not added to requests, allowing commands to be processed correctly.

Description Ilia Meerovich 2014-01-01 12:31:57 UTC

It looks that:
- cdrom.update(null, true, null) passes null to backend instead of discarding null parameter)
 
- and sometimes back-end is not protected from wrong api calls

code:

import org.ovirt.engine.sdk.Api;
import org.ovirt.engine.sdk.decorators.VM;
import org.ovirt.engine.sdk.decorators.VMCdRom;
import org.ovirt.engine.sdk.entities.File;

public class JavaSDKTestDebug {
	private static final String URL = "https://ilia-rhevm.qa.lab.tlv.redhat.com:443/api";
	private static final Boolean debug = false; 
	private static final Boolean noHostVerifictaion = true;

	public static void main(String[] args) throws Exception {
		Api api = new Api(URL, "vdcadmin.tlv.redhat.com", "123456", null, null, null, null, noHostVerifictaion, null, debug);
		File file = new File();
		file.setId("en_windows_7_enterprise_x64_dvd_x15-70749.iso");
		VM vm = api.getVMs().list().get(0);
		VMCdRom cdrom = vm.getCdRoms().list().get(0);
		cdrom.setFile(file);
		cdrom.update(null, true, null);
		api.shutdown();
	}
}

Comment 1 Ilia Meerovich 2014-01-01 12:36:28 UTC

I meant engine log (not jboss server log)

Comment 2 Ilia Meerovich 2014-02-02 12:31:10 UTC

reproduced with ovirt-engine-sdk-java-3.4.0.3-0.1.el6.noarch

Steps for reproduction:
Setup:
1. datacenter, cluster, host (I worked with local storage domain configuration)
2. data domain and iso domain with iso file inside it.

Steps:
1. Create VM 
2. run the above code' and you will get this exception:

Exception in thread "main" 
code  : 500
reason: Internal Server Error

Comment 4 Juan Hernández 2014-02-02 15:31:38 UTC

This was fixed in the rhevm-sdk-java-3.4.0.1-0.1 downstream build, and also in the ovirt-engine-sdk-java-3.4.0.3-1 upstream build available here:

http://jhernand.fedorapeople.org/rpms/ovirt-engine-sdk-java/3.4.0.3-1

Note that you tested with 3.4.0.3-0.1, not with 3.4.0.3-1.

Comment 9 Sandro Bonazzola 2014-02-19 13:41:57 UTC

This bug should be fixed in ovirt-3.4.0-beta3 but it has already a fixed-in-version set and is in state modified instead of ON_QA.
Assignee please fix the bug status and consider adding a reference to ovirt 3.4.0 release notes page if relevant.

Comment 10 Juan Hernández 2014-02-19 14:25:21 UTC

Eyal, has an official build containing this fix already been delivered to QE? If so, can we move to ON_QA?

Comment 11 Eyal Edri 2014-02-19 15:23:34 UTC

QE got AV1 build with includes a newer pkg of rhevm-sdk so i think you can move to ON_QA.

Comment 13 Juan Hernández 2014-03-19 10:16:35 UTC

This bug is about making sure that the SDK doesn't send to the server the parameters which values are null. In order to verify it you need to make sure that the generated PUT request is as follows:

  PUT /api/vms/9f8be70b-bd6d-44ea-91c8-d89c0aee3dbe/cdroms/00000000-0000-0000-0000-000000000000;current=true HTTP/1.1
  Content-type: application/xml
  Filter: false
  Prefer: persistent-auth
  Content-Length: 365
  Host: rhel.example.com:443
  Connection: Keep-Alive
  User-Agent: Apache-HttpClient/4.2.1-redhat-1 (java 1.5)
  Cookie: JSESSIONID=8E2yWPL8WghvfbWtmVfgMrb0.undefined
  ...

The important thing here is that the request must have the "current=true" URL parameter and it mustn't have the "async=null" URL parameter or the "Correlation-id: null" header. If that is ok then this bug is fixed.

The 500 error code that you are getting is a different issue, a server side one, reported in bug 1067407, caused by a NPE when trying to change the current CD for a VM that is down.

Please check this again with a VM that is up.
