Rene Cordier commented on JAMES-2860:
-------------------------------------
Unfortunately, the issue still occurs with our integration tests when trying to
read a big blob that we delete same time. So the tests will stay disabled for
now for BlobStore with Scality/cloudserver
> Read partial blob issue with Scality
> ------------------------------------
>
> Key: JAMES-2860
> URL: https://issues.apache.org/jira/browse/JAMES-2860
> Project: James Server
> Issue Type: Bug
> Reporter: Rene Cordier
> Priority: Major
>
> For some reasons, the test
> readShouldNotReadPartiallyWhenDeletingConcurrentlyBigBlob in
> DeleteBlobContract fails sometimes randomly with the Scality S3 object
> storage implementation.
> It seems sometimes it manages to read partially a blob while deleting it
> concurrently.
> The issue doesn't seem to happen with Swift though...
> ---
> So after having a meeting with people from Scality, this is what we concluded:
> * When there is a delete operation, the blob gets marked as deleted first
> then gets deleted, to avoid an other thread to try to read it same time. So
> it is a bug.
> * this bug was known and seemed to be happening with big blobs in old
> versions. It seems S3 is partitioning blobs when they get bigger than 10MB,
> and that bug was happening then
> * we use an old version of Scality, and since the bug has been fixed on
> newer versions
> * however it seems Scality doesn't maintain anymore docker images on docker
> hub, but the Dockerfile is present on their github
> Solution: we need to generate ourselves our own scality docker image with the
> latest changes (v8) and use it instead of the one we actually use (v6)
