Current (Unreleased) Release Notes¶

2.35.0¶

Account listings now include storage policy information for the containers listed.

Added a new object-expirer configuration option, round_robin_task_cache_size, to adjust the number of tasks to cache before processing. This may be used to trade faster expirer start-up for more lumpy container-server load.

Added a stale_worker_timeout configuration option to the WSGI servers. Once this time elapses following a reload, the manager process will issue SIGKILLs to any remaining stale workers.

Object updater observability improvements:
- Added last start time to recon dumps as object_updater_last.
- Added information (including target account/container) from oldest failed updates to recon dumps, both per-device and aggregated for the node. Use the new async_tracker_max_entries and async_tracker_dump_count options to adjust how many records to collect.

Added the option to tune down ETag validation in the object-server during full-object reads. By default, every full read will continue to have its ETag validated as bytes are streamed to the proxy-server. The etag_validate_pct option may be used to configure approximately what percentage of full-object reads should be validated; reducing this can improve performance when object-servers are CPU-constrained.

Partial reads continue to never have their ETag validated in the object-server. The object-auditor continues to periodically validate every object’s ETag.

The object-expirer configuration options expiring_objects_container_divisor and expiring_objects_account_name are now deprecated.

If a cluster was deployed with a non-standard account name, operators should remove the option from all configs so they are using a supported configuration going forward, but will need to deploy stand-alone expirer processes with legacy expirer config to clean-up old expiration tasks from the previously configured account name.

Removed the use of eval in the xprofile middleware. Note that this middleware is only intended for development purposes and is not intended for use in production systems.

The S3 API no longer requires a Content-MD5 header for DeleteObjects requests when using v4 signatures.

Uploads to containers with object versioning enabled now require a Content-Length or Transfer-Encoding: chunked header, similar to other containers.

Fixed Content-Type and Content-Length headers in account and container HEAD responses (with eventlet>=0.38.0).

Object expiration fixes:
- The object-expirer now better handles errors during listings.
- The object-expirer now respects the internal_client_conf_path configuration option in legacy object-expirer.conf configs.

Separated unlinks-due-to-outdated-updates from unlinks-due-to-fully-processed-updates in logged object-updater stats.

The cooperative_period option for the object-server now affects PUT requests in a way similar to GET responses.

Fixed an issue with the object-reconstructor that would prevent reconstruction of objects with non-ASCII header names.

Fixed an issue with the container-reconciler that could cause reconciler databases to have conflicting rows that could not be resolved.
