A documentation line should be added somewhere to state that this future client is available -- prob in DiracX. |

Done in DIRACGrid/diracx#1135 |
S3Mock is pinned to 3.12.0, which does not support presigned POST uploads and does not validate credentials or signatures. Use SeaweedFS, as DiracX does, with real credentials for the S3 storage elements. This also allows uploads through the S3Gateway to be tested again.
…eClient When /DiracX/FutureClientEnabled/WorkloadManagement/SandboxStore is enabled, sandboxes are uploaded to and downloaded from the DiracX S3 backend using presigned URLs instead of being proxied through the SandboxStore service. Transfers are streamed to disk, retried with a jittered backoff and the checksum embedded in the PFN is verified after download. Sandboxes which are not stored in S3 are still downloaded through their storage element.

FutureClient/SandboxStoreClientwhich uploads, downloads and looks up sandboxes directly against the DiracX S3 backend using presigned URLs, instead of proxying them through theSandboxStoreservice.To test this in CI, the S3Mock container is replaced by SeaweedFS (as used by DiracX). S3Mock 3.12.0 does not support presigned POST uploads and does not validate presigned requests, which was hiding several bugs in the S3Gateway that are also fixed here:
urls.get("Fields")instead of the fields of each URL, so the checksum was never stored on uploadexists()sent a GET to a URL signed for HEADBEGINRELEASENOTES
*WorkloadManagement
NEW: SandboxStoreClient can access the DiracX sandbox store directly when the SandboxStore FutureClient is enabled
*DataManagement
FIX: S3Gateway presigned URLs work with S3 implementations which validate them, and store the checksum on upload
