commit 5858fb7995bb86cb976f90ba3f2712f3fd2d78fa Author: Balazs Gibizer <[email protected]> Date: Wed Jul 19 10:11:32 2017 +0200 placement: proper JOIN order for shared resources There is an existing functional test that proves that shared non custom resource (DISK_GB) mixed with non shared compute resources works. This patch adds a test case where the shared resource is also a custom resource. An issue in the _get_all_with_shared() function where the dict of resource to sharing resource providers that is used to construct the JOIN chain was not being sorted so that non-shared resources were added to the JOIN chain ahead of shared resources. The SQL JOINs that are generated by the _get_all_with_shared() function depend on a specific order. For non-shared resources, an INNER JOIN is done to the preceding derived query whereas for shared resources, a LEFT JOIN is done. If we do the LEFT JOIN followed by INNER JOINs, the SQL expression will produce an incorrect projection.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1705231 Title: Placement returns no allocation candidate for request that needs both compute resources and custom shared resources Status in OpenStack Compute (nova): Fix Released Bug description: When GET allocation_candidate request is sent to the placement api with normal and custom resource requested the placement API returns no allocation candidates. The scenario works properly if the two resources requested are from different providers but non of the is a custom resource.
