Comment 1 Michal Minar 2016-08-18 07:18:01 UTC

To summarize, we'd like Docker, during a push of blob, to:

1. It could try to mount from each remembered association before falling back to full blob upload.
2. Verify if the blob really doesn't exist in the source repository before forgetting its association.
3. Stat() the target repository even if there's no remembered association between blob and the destination repository.

Comment 2 Michal Minar 2016-08-18 15:10:27 UTC

Partial and simple solution is at https://github.com/projectatomic/docker/pull/183

We should propose a more thorough implementation covering comment 1 before submitting upstream though.

Comment 3 Lokesh Mandvekar 2016-08-20 09:45:23 UTC

Moving bug to docker..

Comment 4 Daniel Walsh 2016-08-20 09:52:45 UTC

Michal should we have this patch in docker-1.12 also?

Comment 8 Mike Fiedler 2016-08-23 12:37:10 UTC

Lokesh,  Where can we pick up the new build?   The latest version on the Openshift QE mirror is 	docker-1.10.3-46.el7.10.x86_64

Comment 10 Mike Fiedler 2016-08-23 17:11:36 UTC

Provided sdodson with URL, but documenting here, too:
