[libvirt] Release 0.4.1 of libvirt-java
I have just released 0.4.1 of libvirt java. There are 2 main items in this release: - Better null checking in for Scheduled Parameters which should fix the issues reported on the list. - Error Callbacks to provide better handling of errors encountered by libvirt (virConnSetErrorFunc and virSetErrorFunc). You can access the latest version via the following means: Source Code: http://www.libvirt.org/git/?p=libvirt-java.git;a=summary Bundled Source (tarball and SRPM): http://libvirt.org/sources/java/ Maven: http://libvirt.org/maven2/ RPMS are making their way through F-11 and F12 build systems Thank you! -- bk

Thanks for the update, Bryan, but the problem still persists. In my setup (Xen hosts): Domain.getSchedulerParameters() still raises a NPE. In libvirt.h, _virSchedParameter is defined as follows using a union for the value: struct _virSchedParameter { char field[VIR_DOMAIN_SCHED_FIELD_LENGTH]; /* parameter name */ int type; /* parameter type */ union { int i; /* data for integer case */ unsigned int ui; /* data for unsigned integer case */ long long int l; /* data for long long integer case */ unsigned long long int ul; /* data for unsigned long long integer case */ double d; /* data for double case */ char b; /* data for char case */ } value; /* parameter value */ }; I believe the Java mapping of virSchedParameterValue should be a Union instead of a Structure: public class virSchedParameterValue extends Union {...} Regards, Frederic ------------------ Orange Labs 38-40 rue du General Leclerc 92794 Issy Moulineaux Cedex 9 FRANCE ********************************* This message and any attachments (the "message") are confidential and intended solely for the addressees.

Alright.. let me give it a try. I was not seeing the NPE in the tests I ran. -- bk On 01/25/2010 01:15 PM, frederic.dangtran@orange-ftgroup.com wrote:

I believe the Java mapping of virSchedParameterValue should be a Union instead of a Structure: public class virSchedParameterValue extends Union {...}

I posted a patched jar file at: http://bkearney.fedorapeople.org/libvirt-0.4.1-PATCH.jar The only change was making the struct into a union per your comments. Can you let me now if this solves you NPE? It passes my tests. -- bk On 01/27/2010 08:40 PM, Bryan Kearney wrote:

Yes it works. No longer any NPE when I invoke getSchedulerParameters() on a Xen domain: I can retrieve both the scheduling cap and weight. I guess the problem pops up only when there are more than 1 sched parameter to return with the unmarshalling of the second one going wrong. Frederic On Jan 29, 2010, at 2:56 PM, Bryan Kearney wrote:

Great. I will work on a 0.4.2 release today and send it out. -- bk On 01/29/2010 10:37 AM, frederic.dangtran@orange-ftgroup.com wrote:
