[Engine-devel] Wiki page for introducing entity search
by Shireesh Anjal 28 Feb '12

28 Feb '12

Hi all, Based on my recent experience with entity search, I have created a Wiki page providing step-by-step instructions on introducing entity search for a new entity in oVirt. It is available at following URL: http://www.ovirt.org/wiki/Development/Introducing_Entity_Search Please feel free to contribute to the same in order to correct any discrepancies or enhance the information provided. -- Thanks, Shireesh

[Engine-devel] Do we need ImagesToRemoveList in RemoveImageParameters?
by Yair Zaslavsky 28 Feb '12

28 Feb '12

Hi all, I see the getter code for this field is not used by Engine-Core. We perform removal of the image specified by the imageId parameter. Can we remove this parameter? Yair

[Engine-devel] final fields on entities sent to client
by Tomas Jelinek 28 Feb '12

28 Feb '12

Hi all, as the same entities as the ones used on the server are also sent to the client (e.g. org.ovirt.engine.core.common.businessentities.VM), this entities will than be serialized/deserialized using the GWT serialization. It means, this entities should follow the restrictions given by the GWT serialization: http://code.google.com/webtoolkit/doc/latest/DevGuideServerCommunication.ht… >From it I would like to point out this: "Fields that are declared final are also not exchanged during RPCs, so they should generally be marked transient as well." It means, that no fields which will be sent to client should be marked with the final keyword. Thanks, Tomas

[Engine-devel] Support for stateless nodes
by Mike Burns 27 Feb '12

27 Feb '12

There has been a lot of interest in being able to run stateless Nodes with ovirt-engine. ovirt-node has designed a way [1] to achieve this on the node side, but we need input from the engine and vdsm teams to see if we're missing some requirement or if there needs to be changes on the engine/vdsm side to achieve this. As it currently stands, every time you reboot an ovirt-node that is stateless, it would require manually removing the host in engine, then re-registering/approving it again in engine. Any thoughts, concerns, input on how to solve this? Thanks Mike [1] http://ovirt.org/wiki/Node_Stateless

[Engine-devel] [backend] a little confusion about the quartz jobs
by Laszlo Hornyak 23 Feb '12

23 Feb '12

hi, I was playing with the quartz jobs in the backend and I thought this is an area where some simplification and/or cleanup would be useful. - SchedulerUtil interface would be nice to hide quartz from the rest of the code, but it very rarely used, the clients are bound to it's single implementation, SchedulerUtilQuartzImpl through it's getInstance() method. - It was designed to be a local EJB, Backend actually expects it to be injected. (this field is not used) - when scheduling a job, you call schedule...Job(Object instance, String methodName, ...) however, it is not the _methodname_ that the executor will look for - instead, it will check the OnTimerMethodAnnotation on all the methods. But this annotation has everywhere the methodName as value - JobWrapper actually iterates over all the methods to find the one with the right annotation So a quick simplification could be: - The annotation is not needed, it could be removed - JobWrapper could just getMethod(methodName, argClasses) instead of looking for the annotation in all of the methods - I am really not for factoryes, but if we want to separate the interface from the implementation, then probably a SchedulerUtilFactory could help here. The dummy implementation would do just the very same thing as the SchedulerUtilQuartzImpl.getInstance() - I would remove the reference to SchedulerUtil from Backend as well, since it is not used. Really _should_ the Backend class do any scheduling? Please share your thoughts. Thank you, Laszlo

[Engine-devel] reviewer needed for schedulerutil cleanup
by Laszlo Hornyak 22 Feb '12

hi, As we previously agreed, I renamed the SchedulerUtil to SchedulerManager and removed the OnTimerAnnotation, can someone please review? http://gerrit.ovirt.org/#change,2140 Thanks, Laszlo
