------=_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?

28 Nov '13

Hi, we're going to branch and build oVirt 3.3.2 beta TODAY. A bug tracker is available at [1] and it shows only 3 bugs still blocking the release: Whiteboard Bug ID Summary storage 1022961 Running a VM from a gluster domain uses mount instead of gluster URI virt 1025829 sysprep floppy is not attached to Windows 2008 R2 machine - even when specifically checked in Run Once virt 1029885 cloud-init testcase does not work in engine 3.3.1 Please provide an ETA for the above bugs. The following is a list of the non-blocking bugs still open with target 3.3.2: Whiteboard Bug ID Summary infra 1017267 Plaintext user passwords in async_tasks database infra 987982 When adding a host through the REST API, the error message says that "rootPassword" is required,... infra 1020344 Power Managent with cisco_ucs problem integration 1022440 AIO - configure the AIO host to be a gluster cluster/host integration 902979 ovirt-live - firefox doesn't trust the installed engine integration 1021805 oVirt Live - use motd to show the admin password integration 1026930 Package virtio-win and put it in ovirt repositories integration 1026933 pre-populate ISO domain with virtio-win ISO network 1019818 Support OpenStack Havana layer 2 agent integration network 987999 [oVirt] [provider] Add button shouldn't appear on specific provider network 987916 [oVirt] [provider] Dialog doesn't update unless focus lost network 906313 [oVirt-webadmin] [setupNetworks] "No valid Operation for <network_name> and Unassigned Logical Networks panel" network 1023722 [oVirt-webadmin][network] Network roles in cluster management should be radio buttons network 997197 Some AppErrors messages are grammatically incorrect (singular vs plural) storage 1029069 Live storage migration snapshot removal fails, probably due to unexpected qemu-img output storage 987917 [oVirt] [glance] API version not specified in provider dialog storage 1016118 async between masterVersion : can't connect to StoragePool ux 906394 [oVirt-webadmin] [network] Loading animation in network main tab 'hosts' and 'vms' subtab is stuck on first view... virt 1007940 Cannot clone from snapshot while using GlusterFS as POSIX Storage Domain Please add the bugs to the tracker if you think that 3.3.2 should not be released without them fixed. For those who want to help testing the bugs, I suggest to add yourself as QA contact for the bug and add yourself to the testing page [2]. Maintainers are welcomed to start filling release notes, the page has been created here [3] [1] https://bugzilla.redhat.com/1027349 [2] http://www.ovirt.org/Testing/Ovirt_3.3.2_testing [3] http://www.ovirt.org/OVirt_3.3.2_release_notes Thanks, -- Sandro Bonazzola Better technology.

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

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

The idea behind the version splitting was: 1) We have a device with a feature that doesn't work correctly with version 3.3, but it's fixed in 3.4 2) By specifying custom property per version we cane disable this feature for 3.3 and enable for 3.4 > The custom properties are extensions which might or might not be available to > a certain VM, I don't see how having different sets of custom properties per > version (what version, DC version, cluster version?) would make any > difference - either the VM can utilize the extension given some state of the > system, or it can't, but the determining factor is not the version but > rather the availability of the extension. > For example, I can have a hook for vNIC altering some property installed on > host A and not host B, if the VM runs on host A it will get this capability > and on host B it won't, regardless the DC version the VM is in. > > This is not to say we shouldn't block custom properties on the engine-VDSM > API level since it's only available since 3.3, but this is handled by > another config value (SupportCustomDeviceProperties) which is not alterable > by the user. > So basically, I think splitting the value per version is over complication > and see no added value to the users, just more maintenance should they > choose to use this feature. > > Your thoughts please. AFAIK only network and storage team wanted to use device custom properties in 3.3 version, but I'm not sure what's current usage status. But IMHO it's too late for 3.3 to change specification ...

[Engine-devel] Problem building 3.3.1 branch
by Bob Doolittle 21 Nov '13

21 Nov '13

Hi, I'm trying to build engine for the first time and running into a build error. I'm a seasoned Unix developer, but new to some aspects of Linux development like git and maven, so I could be doing something naive. I'm following the instructions here: http://www.ovirt.org/OVirt_Engine_Development_Environment I did a clone of the engine repository, and did "git checkout -b myengine origin/ovirt-engine-3.3.1" to create my own branch based on 3.3.1 (current - I realize it's not quite done). Then, when I did "make install-dev PREFIX=$HOME/ovirt-engine" it failed when building the "Engine Web Root", specifically in the FileServletTest. Relevant build log is here: http://pastebin.com/JRcyWvtr Can anyone suggest what I've done wrong, or whether there's a problem with the repository at the moment? I'd appreciate any guidance. Thanks, Bob
