[Engine-devel] Missing vfsType from VDSM conList.
by snmishra＠linux.vnet.ibm.com 03 Mar '13

03 Mar '13

Trying to create a new storage domain using a glusterfs data center. The operation is failing because vfsType is not being passed to VDSM. Debugging on engine, I can see that Frontend.runActionImpl() is called with vfsType correctly set but it doesn't seem to reach VDSM. Any clues as to what may be causing this behaviour? When I run the test with posixfs, I see - Thread-169::INFO::2013-03-01 11:11:30,889::logUtils::44::dispatcher::(wrapper) Run and protect: connectStorageServer(domType=6, spUUID='00000000-0000-0000-0000-000000000000', conList=[{'port': '', 'connection': 'vm-vdsm-de-1:dpkvol3', 'iqn': '', 'portal': '', 'user': '', 'vfs_type': 'posixfs', 'password': '******', 'id': '00000000-0000-0000-0000-000000000000'}], options=None) but with glusterfs, I get - Thread-73::INFO::2013-02-27 15:40:57,750::logUtils::44::dispatcher::(wrapper) Run and protect: connectStorageServer(domType=7, spUUID='00000000-0000-0000-0000-000000000000', conList=[{'connection': 'vm-vdsm-de-1:dpkvol3', 'iqn': '', 'portal': '', 'user': '', 'password': '******', 'id': '00000000-0000-0000-0000-000000000000', 'port': ''}], options=None) Notice that vfsType is not passed in second case.

I have recently seen several people getting into trouble building because they are using the obsolete maven 2. Please make sure that you use maven 3 for all your builds. -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif. Gorbea 3, planta 3ºD, 28016 Madrid, Spain Inscrita en el Reg.

[Engine-devel] Rebasing a patch on an updated dependency
by Morrissey, Christopher 27 Feb '13

27 Feb '13

Hi All, I have a patch, http://gerrit.ovirt.org/#/c/11783/, that is dependent on another unmerged patch and the dependent patch has been updated with a new patch set. I know I need to somehow rebase my patch on the updated dependent patch set, but I'm new to git and gerrit and have not been able to figure out the right combination of git commands to accomplish this. Any ideas on what steps I need to take? Thanks! -Chris Chris Morrissey Software Engineer NetApp Inc. 919.476.4428

[Engine-devel] Engine table comments

This is a multi-part message in MIME format. --------------090900020406030601070406 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Hi, I would like to propose to create a patch assigning sql comment to each Engine table. The comments will be a part of the exported DB schema report, too. The terminology is not always consistent across all application layers, so for the newcomers it would be easier to understand the model. But, what would be general guidelines? I recommend to use singular form of entity name as used from end-user point of view (if somehow visible, of course), or just used frequently inside code. Examples: storage_pool ... Data center vds_groups ... Cluster but: vm_static ... Virtual machine configuration vm_dynamic ... Virtual machine runtime data vm_statistics ... Virtual machine statistics data ... etc. This command prepares a template for the patch: /psql engine -U postgres -c "select 'COMMENT ON TABLE ' || relname || ' IS ''TODO'';' sql from pg_stat_user_tables t WHERE schemaname='public' order by t.relname" > comments_to_do.sql// / or just I can prepare a page on the wiki with table containing table names and volunteers :-) can propose simple understandable comments for known tables. Is it useful? Thanks.

[Engine-devel] Changing Gerrit -1 message
by Ofer Schreiber 25 Feb '13

25 Feb '13

I feel that the current "-1 I would prefer that you didn't submit this" message in Gerrit is pretty rude, as usually those -1 reviews are just small fix-ups in the code itself. Any thoughts about a more suitable "-1" message? I thought about "-1 Please fix your code" or something similar. Thanks, Ofer Schreiber

[Engine-devel] Secret quartz update checks

Hi, While deploying a development setup in a new machine I noticed the following quartz line: 2013-02-25 16:10:28,546 INFO [org.jboss.as.server] (DeploymentScanner-threads - 2) JBAS018559: Deployed "engine.ear" 2013-02-25 16:10:30,143 INFO [org.quartz.utils.UpdateChecker] (Timer-1) New Quartz update(s) found: 2.1.6 [http://www.terracotta.org/kit/reflector?kitID=default&pageID=QuartzChangeLog] This is suggesting that quartz is reaching out to verify on new updates. Do we really need it? Do we really want it?

[Engine-devel] REST API calls from the GUI
by Libor Spevak 25 Feb '13

25 Feb '13

Hi, I would like to ask, if there have been discussions about an option to call REST API services directly from the Frontend (GWT layer)? GWT compiles Java frontend-side to Javascript, calls to backend services are performed "transparently" by the framework using AJAX support. But, there is still a need to have a special set of data objects and the server-side logic can duplicate. Java REST API SDK enables to build "thick" client. The calls are realized using e.g. Apache HttClient and supported libraries. I think the requirements of GWT can be a little bit different, but something overlaps. I found several links about REST API support from GWT, so there is something for inspiration... - http://www.spiffyui.org/ - http://www.zackgrossbart.com/hackito/gwt-rest/ - http://code.google.com/p/gwt-rest/ - http://restygwt.fusesource.org/ But, do you think it would be useful and what drawbacks can occur (authentication, authorization, response times, need to support larger set of services, painful refactoring, ...)? Regards, Libor
