Re: [Engine-devel] Weird behavior of multiple SetVmTicket query

------=_Part_22230002_1751095465.1384256418493 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Forwarding this email to engine-devel so that backend maintainers are aware of this issue. Looking at the code: - MultipleActionsRunner#Execute first creates and "validates" all commands: A. the "for" block which iterates over getParameters() 1-> validate correlation ID, if OK create and add command, otherwise add returnValue B the "if" block which tests getCommands().size() 1-> if single command to execute, add its "canDoActionOnly" returnValue, which is returnValue with canDoAction but without actual result object 2-> if multi commands to execute, execute chunks of max. 10 threads (sequentially, ThreadPoolUtil.invokeAll returns after all threads complete), same returnValue as above C. the "if" block which tests canRunActions 1-> all commands are executed within SINGLE THREAD due to ThreadPoolUtil.execute(Runnable), which is kind of weird comapred to how returnValues are prepared (see B2) 2-> when executing command, code DOES NOT CARE about its returnValue, i.e. returnValue was already prepared (see B) and command execution should just update it The problem (I think) is that C1 starts a different thread (to execute all commands) and immediately returns, i.e. code doesn't wait for thread to complete. This is why returnValues are observed on frontend as inconsistent. Additionally, we're also mixing of two different things: canDoAction processing and returnValues processing. IMHO this should be refactored to make code easier to read. Changes done by Alex (patch attached): X1. returnValues changed to Collections.synchronizedList -> this means all access to returnValues is now serial -> iteration over synchronizedList should also be enclosed in "synchronized (list)" block, so this: for (VdcReturnValueBase value : returnValues) ... should be this: synchronized (returnValues) { for (VdcReturnValueBase value : returnValues) ... } X2. commented-out original command execution via ThreadPoolUtil.execute(Runnable) -> new RunCommands method invokes all commands each in separate thread via ThreadPoolUtil.invokeAll -> returnValues list is explicitly updated Guys, what do you think?

Re: [Engine-devel] [vdsm] Multiple graphics framebuffers - VDSM support
by Frantisek Kobzik 27 Nov '13

Hi guys, I created a wiki page with the feature: http://www.ovirt.org/Features/Multiple_Consoles It contains information about possible redesign of Engine<->VDSM communication. I'd appreciate if you take a look at it since it's not trivial change. I welcome opinions from both engine and vdsm devels. Cheers, F. ----- Original Message ----- From: "Frantisek Kobzik" <fkobzik(a)redhat.com> To: vdsm-devel(a)lists.fedorahosted.org Sent: Monday, November 25, 2013 2:23:59 PM Subject: Re: [vdsm] Multiple graphics framebuffers - VDSM support Hi, it's been some time since the original mail, so I'm sending updated information. ----- Original Message ----- From: "Frantisek Kobzik" <fkobzik(a)redhat.com> To: vdsm-devel(a)lists.fedorahosted.org Sent: Thursday, November 7, 2013 11:47:46 AM Subject: [vdsm] Multiple graphics framebuffers - VDSM support Dear VDSM developers, I'm working on a patch that allows running a VM with multiple graphics framebuffers. This is handy when you want to run a VM with both SPICE and VNC. It's a 3.4 feature and it will certainly need a change in vdsm. Here is a list of changes in VDSM that are needed for this funcionality: a, Sending graphics/video (engine->vdsm) - currently we send two things: 1, "display" value (qxl/vnc [wat]) - vdsm uses this for determining if the graphics server is SPICE or VNC - this attribute is not really correct - it mixes up semantics of graphic framebuffer and videocard together. I believe this attribute should only contain information about the graphics ('spice', 'vnc' or 'spice,vnc' if you want both). if this the case, do you think we should rename the attribute to, let's say, 'graphics'? Is it even possible with regard to backward compatibility? or should I reuse 'display' attribute? 2, video device (json representation of the video card) - this is correct b, Reporting graphics ports (vdsm->engine) - currently we report 2 graphic ports ('displayPort' and 'secureDisplayPort') - if we want multiple framebuffers, we must report more ports (for VNC and SPICE together that would mean 3 ports (2 for spice, one for vnc). - there are two possible solutions for this: 1, ditch 'displayPort' and 'secureDisplayPort' and add new 'spicePort', 'spiceSecurePort', 'vncPort' fields or some kind of two level dict: { protocol -> secured/unsecured -> portNumber } 2, keep 'displayPort' and 'secureDisplayPort' and introduce new 'additionalDisplayPort' This would be friendlier to backward compatibility, but it's extremely ugly because of unclear semantics of the fields (in case of SPICE+VNC 'displayPort' and 'secureDisplayPort' would be related to SPICE, 'additionalDisplayPort' would be the VNC port. In case of VNC only, the 'displayPort' would be suddendly VNC port... ewww). I'd be very happy if you share your opinion about these changes. Cheers, Franta. _______________________________________________ vdsm-devel mailing list vdsm-devel(a)lists.fedorahosted.org https://lists.fedorahosted.org/mailman/listinfo/vdsm-devel

[Engine-devel] Java Newbie: Renaming some functions to fix findbugs warnings
by Adam Litke 22 Nov '13

22 Nov '13

Hello, I am working on resolving some warnings produced by findbugs and am looking for some advice on how to properly resolve the problem. The Frontend class has several pairs of methods where a capitalized version is a deprecated static form and the camelCase version is the instance method. For example: @Deprecated public static void RunQuery(...) - and - public void runQuery(...) In both cases the parameters are the same so simply renaming RunQuery to runQuery will result in a conflict. Since I am new to Java and the ovirt-engine project I am looking for some advice on how to fix the function name without breaking the code or people's sense of aesthetics. Since this is a deprecated function, would it be terrible to rename it to 'runQueryStatic' or 'runQueryDeprecated'? Since the language provides syntactic annotations for 'static' and 'deprecated', both of these names feel dirty but I am not sure what would be better. Thanks for helping out a newbie! --Adam
