Gluster/virt ports clarifications.
by Leon Goldberg 03 Apr '17

03 Apr '17

Hey, We're gathering information regarding the ports we open as part of the firewalld migration research. We have most of the current ports covered by either firewalld itself or by 3rd party packages, however some questions remain unanswered: IPTablesConfigForVirt: - serial consoles (tcp/2223): Is this required? can't find a single reference to a listening entity. Either way, I couldn't find a relevant service that provides it. IPTablesConfigForGluster: - Gluster swift (tcp/8080): Doesn't appear in Gluster's firewalld service. Should be added to Gluster's firewalld service? - tcp/39543 and tcp/55863, appear under "status". Couldn't find a relevant service that provides them. Should be added? (and if so, where?) - nlockmgr (tcp/38468, udp/963, tcp/965): tcp/38468 appears in gluster's service. Couldn't find a relevant service that provides the other two. Should be added? (and if so, where?) - ctdbd (tcp/4379): Couldn't find a relevant service that provides this. Should be added? (and if so, where?) Thanks, Leon

oVirt in the new programming-journal
by Arik Hadas 03 Apr '17

03 Apr '17

Hi everyone, I would like to share a paper that has just been published in the new programming-journal (that is called "The Art, Science, and Engineering of Programming") named "Language Oriented Modularity: From Theory to Practice" [1]. The evaluation of the proposed approach for language-oriented modularity is done in part with oVirt (specifically, with the engine) and also the difficulty/inability to reuse a DSAL that was designed for one application in a different application is demonstrated with oVirt and muCommander [2]. I hope you will find it interesting :) [1] http://programming-journal.org/2017/1/10/ [2] https://github.com/mucommander Regards. Arik

oVirt master UI now uses GWT 2.8
by Vojtech Szocs 02 Apr '17

02 Apr '17

Hello folks, we're using the latest GWT version in master UI now [1]. We can start using Java 8 syntax in our frontend code. GWT 2.8 also brings partial support for Java 8 standard library APIs, see "JDK emulation" at [2] for details. [1] https://gerrit.ovirt.org/#/q/topic:gwtupgrade [2] http://www.gwtproject.org/release-notes.html#Release_Notes_2_8_0_RC1 Effectively, all Engine (Java Maven) modules [3] are now Java 8 source & target compilant. [3] except backend/manager/modules/extensions-api-root With this upgrade, the GWT UI should be a bit faster - generated JavaScript should take advantage of new web APIs (e.g. using ES6 Maps to implement Java HashMap) as well as general performance improvements (e.g. using a faster "long" emulation). GWT 2.8 removes deRPC (direct-eval RPC) mechanism but that's OK because we're already using the standard GWT RPC [4]. [4] https://gerrit.ovirt.org/#/c/65735/ There are no changes to existing build & development process: - debugging via Java IDE (aka Classic Dev Mode) remains the default debug method - debugging via browser (aka Super Dev Mode) can be enabled via DEV_BUILD_GWT_SUPER_DEV_MODE flag [5] [5] example: $ make gwt-debug DEBUG_MODULE=webadmin DEV_BUILD_GWT_SUPER_DEV_MODE=1 Note that in GWT 2.8 the Super Dev Mode is the new default debug method (with Classic Dev Mode being deprecated). There are still some post-upgrade tasks to do, we're tracking them on Trello: https://trello.com/b/o26RrVLz/post-gwt-2-8-upgrade-tasks If you encounter any issues related to GWT compilation or debugging, let me know. Regards, Vojtech

Re: [ovirt-devel] Interest in contributing to oVirt
by Konrad Djimeli 31 Mar '17

31 Mar '17

Hello Yaniv, Thanks very much for the response. I am currently trying to develop a proposal for this project but I have not yet been able to successfully setup oVirt. I just realized I could not install the oVirt-engine an Ubuntu 14, so I am currently trying to download and install Fedora 23, where I intend to setup the oVirt-engine. I would then use another machine with Ubuntu for the host. Please with respect to this project I would like to know if I am also required compile and install the source code for oVirt-engine or do I only need to build and install ovirt4cli.

[ANN] oVirt 4.1.1 Async release candidate
by Sandro Bonazzola 30 Mar '17

30 Mar '17

Hi, following oVirt 4.1.1 GA the oVirt team identified some bugs worth to be addressed out of the usual release cycle. For this reason an async release including these fixes is under preparation. An update to the following packages have been pushed to the pre-release repository for testing. - ovirt-engine-4.1.1.7 - vdsm-4.19.10.1 - ovirt-release41-4.1.1.1_rc1 - ovirt-web-ui-0.1.2-4 - cockpit-ovirt-0.10.7-0.0.16 In order to test it, you'll need pre-release repository enabled: yum install http://resources.ovirt.org/pub/yum-repo/ovirt-release41-pre.rpm An update to release notes including bugs related to above packages and updates applied in bugzilla documentation texts has been pushed to https://github.com/oVirt/ovirt-site/pull/888 for review. On behalf of the oVirt team, -- SANDRO BONAZZOLA ASSOCIATE MANAGER, SOFTWARE ENGINEERING, EMEA ENG VIRTUALIZATION R&D Red Hat EMEA <https://www.redhat.com/> <https://red.ht/sig> TRIED. TESTED.

Writing SQL queries in DAO code
by Yevgeny Zaspitsky 30 Mar '17

30 Mar '17

Hi All, Recently I had a task of performance improvement in one of our network related flows and had some hard time following our DAL code and one of the outcomes of the task was defining a couple of new quite simple, but neat queries. When I came to coding those new queries I remembered how hard was following the existing DAL code, I decided to make my own new methods clearer. So I created [1] and [2] patches. Everything is quite standard there beside the fact that they do not use any stored procedure, but use SQL directly, IMHO by that they save time that I spent in trying to follow what a DAO method does. Looking into the method code you get the understanding of what this method is all about: - no looking for a stored procedure name that is buried in the DAO class hierarchy - no looking for the SP definition So I'd like to propose moving towards this approach in general in all cases when nothing beyond a simple SQL is needed (no stored procedure programming language is needed). >From my experience with the performance improvement task it looks like people avoid adding new queries for a specific need of a flow, instead they use the existing general ones (e.g. dao.getAllForX()) and do the actual join in the bll code. IMHO the proposed approach would simplify adding new specific queries and by that would prevent a decent part of performance issues in the future. I do not propose changing all existing SP's to inline queries in a once, but to allow adding new queries this way. Also we might consider converting relatively simple SP's to inline SQL statements later in a graduate way.
