Request for new git repos: ovirt-engine-sdk-python-specs, ovirt-engine-sdk-java-specs, ovirt-engine-cli-specs
by Juan Hernández 12 Jan '15

12 Jan '15

Hello, Please create the following new git repositories: ovirt-engine-sdk-python-specs ovirt-engine-sdk-java-specs ovirt-engine-cli-specs They will be used to manage the RPM spec files (also scripts, patches, and in general anything needed for building RPMs) of the Python SDK, the Java SDK, and the CLI. Each repository will have branches for each pair of oVirt major release and supported distribution: ovirt-3.5-el6 ovirt-3.5-el7 ovirt-3.5-fc20 ovirt-3.5-fc21 ovirt-3.6-el6 ... Initially I will be the maintainer of these repositories. Once these repos are created the specs will be added to them and eventually removed completely from the main repositories of the SDKs and the CLI. Thanks in advance, Juan Hernández -- Dirección Comercial: C/Jose Bardasano Baos, 9, Edif. Gorbea 3, planta 3ºD, 28016 Madrid, Spain Inscrita en el Reg. Mercantil de Madrid – C.I.F.

engine.ear fails on current ovirt-3.5 branch
by Adam Litke 08 Jan '15

Hi all, Back from a long vacation I decided to build a fresh engine from the tip of the ovirt-3.5 branch (447ff7) and to my dismay, the deployed build will not start within jboss.

fyi ovirt-engine\api fails over f19
by ybronhei 07 Jan '15

07 Jan '15

Hey guys, I faced a problem with javax/activation/api which is missing in f19. Therefore /api threw exception and I couldn't have any restapi reply from engine. To workaround with that instead upgrading I removed the dependency from share/ovirt-engine/modules/org/codehaus/jackson/jackson-xc/main/module.xml and it works. till now i haven't noticed anything strange without it..

vdsm to require newer pyflakes on el6
by Dan Kenigsberg 07 Jan '15

07 Jan '15

As mentioned on http://gerrit.ovirt.org/#/c/36434/ , vdsm's `make pyflakes` has been broken so that it gives a false sense of security, as it tests very few modules. During this period, we've acquired code that triggers pyflakes-0.4.0-2.el6.noarch.rpm of epel6. ./vdsm/sos/vdsm.py.in:25: redefinition of unused 'RedHatPlugin' from line 22 ./vdsm/sos/vdsm.py.in:25: redefinition of unused 'Plugin' from line 22 ./vdsm/virt/guestagent.py:144: redefinition of function 'guestDiskMapping' from line 140 vdsm/get-conf-item:11: redefinition of unused 'config' from line 8 vdsm/set-conf-item:13: redefinition of unused 'config' from line 10 make: *** [pyflakes] Error 1 I suggest requiring Vdsm developers to use a newer version of pyflakes, even on el6, such as the one provided by http://danken.fedorapeople.org/pyflakes-0.8.1-3.el6.noarch.rpm as the alternative is to add silly code in order to quiesce an ancient pyflakes. This would server as a stop-gap until we live up to our plan of including pep8 and pyflakes as git submodules, so that all vdsm developers use the same verification tool on all platforms. Dan.
