Resolution: Fixed
> [DirectBinaryAccess] Verify that binary exists in cloud before creating
> signed download URI

>
> Key: OAK-7998
> URL: https://issues.apache.org/jira/browse/OAK-7998
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: blob-cloud, blob-cloud-azure
> Affects Versions: 1.10.0
> Reporter: Matt Ryan
> Assignee: Matt Ryan
> Priority: Major
> Fix For: 1.16.0, 1.10.4
>
>
> The direct binary access download logic doesn't actually verify that the
> requested blob is available in the cloud before creating the signed download
> URI. It is possible that a user could request a download URI for a blob that
> is "in the repo" but hasn't actually been uploaded yet.
> We should verify this by uploading a new blob, preventing it being uploaded
> to the cloud (retain in cache), and then request the download URI. We should
> get a null back or get some other error or exception; if we get a URI it
> would return an HTTP 404 if the blob is not actually uploaded yet (maybe this
> would also be ok).
