LiangFang@abhishekk sorry for the late response, these two patches are originally from the requirement of our partner.06:04
LiangFang@abhishekk This was a small usability improvement to help the user distinguish the glance backend type in a multi backend environment06:04
LiangFangList the related review: https://review.openstack.org/#/c/605006/ and https://review.openstack.org/#/c/605014/06:05
abhishekkLianFang, if possible bring this in today's meeting, so that we can get the views of others06:06
abhishekkfor new multiple backend feature which was added as experimental in rocky, stores information is shown in get (show) call06:07
LiangFang@abhishekk Thanks for suggesting me the weekly meeting, I already added my another topic there, and it seems agenda is nearly full06:07
abhishekkLiangFang, ok, let see if we get some time for open discussion then we can bring this topic06:08
LiangFangok06:08
LiangFangshow call, do you mean glance image-show?06:10
abhishekkyes06:11
LiangFangbut this can only show one image06:11
abhishekkyes06:11
LiangFang@abhishekk Could you please take a look this BP? https://blueprints.launchpad.net/openstack/?searchtext=specify-image-size-to-avoid-backend-resize06:14
abhishekkLiangFang, yes06:15
LiangFangand the related spec: https://review.openstack.org/#/c/608400/06:15
LiangFangThe is in today's meeting agenda06:16
LiangFangThis is06:16
LiangFangThank you very much06:16
LiangFangThis is to solve the issue that: when uploading cinder volume to image, glance_store don't know the image size, so the backend need to resize the image when it received every new chunk of data06:19
LiangFangso this BP/spec is to find a way to convey the image size from cinder to glance at the beginning of uploading06:21
LiangFangso that glance backend such as ceph can allocate an image large enough, and don't need to resize any more06:22
LiangFangThe way this BP selected is: convey the image size via HTTP header06:23
LiangFangThe http header is not suitable to convey some critical data because the header may be ignored by some intermediate although this rarely happen06:26
LiangFangbut it don't matter here. Because if the image size in header is lost, the subsequent behavior is just like current code (backend will do resize)06:28
*** dims has quit IRC06:29
LiangFangin fact, in current code, there're also some codes that using http header to convey info. e.g. hdrs['x-image-meta-store'] = backend06:31

*** mvkr has quit IRC16:16
imacdonnrosmaita: Replied to your review of the spec-lite .... do we need to discuss allowing validation_data when updating an "active" images (provided the values aren't different)? Perhaps I should call that out explicitly in the spec16:40
rosmaitalooking16:43
rosmaitaimacdonn: you picked up on exactly what i was wondering about16:45
imacdonnrosmaita: right... so, any disagreement? I think I'll add a sentence to the spec... something like "The validation_data object may be included when updating an image in active status, but must not contain different values"16:48

rosmaitaimacdonn: i need to get lunch, maybe that will make me think better.  In any case, i think you should add the sentence to the spec so that this is completely clear to all the reviewers17:03
imacdonnrosmaita: agreed. will do. thanks.17:03
