<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I'd like to ask for a feature freeze exception for using oslo-incubator service framework in glance, based on the following blueprint:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><a href="https://blueprints.launchpad.net/glance/+spec/use-common-service-framework">https://blueprints.launchpad.net/glance/+spec/use-common-service-framework</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The code to implement this feature is under review at present.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">1. Sync oslo-incubator service module in glance: <a href="https://review.openstack.org/#/c/117135/2">
https://review.openstack.org/#/c/117135/2</a><o:p></o:p></p>
<p class="MsoNormal">2. Use Launcher/ProcessLauncher in glance: <a href="https://review.openstack.org/#/c/117988/">
https://review.openstack.org/#/c/117988/</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If we have this feature in glance then we can able to use features like reload glance configuration file without restart, graceful shutdown etc.<o:p></o:p></p>
<p class="MsoNormal">Also it will use common code like other OpenStack projects nova, keystone, cinder does.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are ready to address all the concerns of the community if they have any.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks & Regards,<o:p></o:p></p>
