---------------------------------
Assignee: Shuo Huang
> Support PutBucketObjectLockConfiguration
> ----------------------------------------
>
> Key: HDDS-16487
> URL: https://issues.apache.org/jira/browse/HDDS-16487
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Chung-En Lee
> Assignee: Shuo Huang
> Priority: Major
>
> Implement the S3 {{PutBucketObjectLockConfiguration}} operation to enable
> Object Lock and configure default retention rules on Ozone buckets (OBS
> layout only). This task spans S3 api and ozone java api.
>
> {*}1. S3 Gateway ({{{}hadoop-ozone/s3gateway{}}}){*}:
> * Add route handler for {{{}PUT /\{bucket}?object-lock{}}}.
> * Parse incoming {{ObjectLockConfiguration}} XML payload:
> ** Extract {{ObjectLockEnabled}} (must be {{{}Enabled{}}}).
> ** Parse optional {{Rule}} / {{DefaultRetention}} ({{{}Mode{}}}:
> {{GOVERNANCE}} or {{{}COMPLIANCE{}}}, {{Days}} or {{{}Years{}}}).
> * Validate request payload and map errors to standard S3 error codes (e.g.,
> {{{}MalformedXML{}}}, {{{}InvalidArgument{}}}).
> * Forward the request to OM via the client protocol.
> {*}2. Protobuf Protocol ({{{}OmClientProtocol.proto{}}}){*}:
> * Add client RPC messages:
> ** {{SetBucketObjectLockConfigRequest}} (contains volume name, bucket name,
> and {{{}RetentionConfig{}}}).
> ** {{{}SetBucketObjectLockConfigResponse{}}}.
> * Register the new request type in {{Type}} enum and OM request dispatching
> pipeline.
> {*}3. {{OMBucketSetObjectLockConfigRequest}}{*}:
> * {*}{{preExecute}}{*}:
> ** Authorize the caller against the Ranger action
> {{{}PutBucketObjectLockConfiguration{}}}.
> ** Perform fail-fast sanity checks on input parameters (e.g., duration $>
> 0$, valid retention mode).
> ** Verify the bucket exists and its bucket layout is {{OBJECT_STORE}} (OBS);
> reject if it is FSO or Legacy.
> * {*}{{validateAndUpdateCache}}{*}:
> ** Acquire bucket write lock.
> ** Enforce immutability: if {{objectLockEnabled}} is already {{{}true{}}},
> reject any attempt to disable it ({{{}false{}}}).
> ** Update {{OmBucketInfo}} with {{objectLockEnabled = true}} and update
> {{{}defaultRetention{}}}.
> ** Commit the updated {{OmBucketInfo}} to {{BucketTable}} cache and RocksDB.
> h4.
