From 3f3a8f11571a71770f08bc2ef48562300b44d9f7 Mon Sep 17 00:00:00 2001 From: John Griffith Date: Sat, 12 Dec 2015 18:32:57 +0000 Subject: [PATCH] Fix invalid cache image-volume creation During the volume ref creation in clone_image_volume we were including a _name_id attribute which is invalid in the base olso object. The result is silent failure for a key error. Note that the comments for the column in the db specifcally state "do not call directly". The variable is also denoted as private by the _ prefix. Fix this by just popping the "_name_id' attribute. In addition there were a number of things that needed some cleanup: 1. Don't iterate over list of tuples to get K/V for dict Just use Dict(xxxx) 2. Don't use delete dict.key This isn't safe, because if the key DNE you'll get a key exception Instead use pop which is safe if key DNE 3. Add an error message when this fails, because currently the logs don't give an operation a chance of knowing it failed, let alone an opportunity to debug it Finally the cache volume creation is still calling the db directly and doing a resource create as opposed to using the new volume object create handler. I went ahead and converted this to use objects, however that resulted in breaking two of the volume-->image unit tests that use cinder as a glance backend. I've opened bug 1525773 for those issues and added a skip to the tests in question.
