* s3: abort a completed upload's leftover directory metadata-only A .uploads/<id> directory can outlive the object it completed into when the commit's metadata-only removal failed or the gateway died in between; the restored part entries then share chunks with the published object. AbortMultipartUpload deleted the directory recursively, chunks and all, so aborting such a leftover destroyed a committed object (#11382). Run the same check s3.clean.uploads gained in #11375 before deleting: when the object entry or a version file under <key>.versions carries the upload id, remove .uploads/<id> metadata-only and answer the abort; when the lookup cannot decide, refuse with InternalError rather than risk live chunks. * s3: apply the completed-upload check to lifecycle MPU abort lifecycleAbortMPU ran the same destructive recursive delete on .uploads/<id>. Reuse uploadCompleted so a leftover whose object entry or version file carries the upload id is removed metadata-only, and an undecidable lookup retries later instead of freeing live chunks. * s3: serialize abort's upload-dir delete with the object's commit The completed check alone leaves a race: abort can read completed=false, then an in-flight completion publishes the object over the same part chunks before the recursive delete frees them. Run the check and delete inside the object write lock, which non-routed completions hold for their whole finalize. With an owner, send the data delete as an ObjectTransaction on the object's lock key — a routed commit then either loses its upload-exists precondition after our delete or has already stamped the object, which the transaction's IF_EXTENDED_NOT_EQUAL condition detects and falls back to a metadata-only remove. lifecycleAbortMPU shares removeUploadDir so both callers get the same ordering. * s3: check for an empty object before resolving its write owner * s3: check completion at the abort's resolved object key An upload record missing ExtMultipartObjectKey skipped the completed check entirely even though the request's Key names the object.
