Changes

• Reduced timeout for Gateway's caches to acquire a connection to Swarm Storage nodes. This avoids incoming connections triggering file handle limits with threads stuck in ScspObjectCache, requiring a "systemctl cloudgateway restart". (CLOUD-3853)

• Gateway 8.1.0 is required when using a search feed created with Swarm 16.1.2 search.perDomainIndex=True. No gateway.cfg changes are needed. Please remember to restart Gateway whenever the default search feed is changed. (CLOUD-3988)

• Added a policy action ListAllMyBuckets for AWS compatibility, to allow a listing of all the bucket names in a domain. Previously ListDomain permission was required but that can also allow for the listing of objects within buckets via SCSP. Enabling this action requires using the Content UI policy editor in "json" mode, at the tenant or domain level. (CLOUD-3526)

• For improved compatibility with AWS S3, Gateway 8.1.0 now allows object locking retention dates earlier than the bucket default. (CLOUD-3800)

• Gateway 8.1.0 cloudgateway_audit.log now includes trailing fields on most requests that indicate the milliseconds spent in different stages. (CLOUD-3902)

• Dependencies had been updated to avoid all High severity security vulnerabilities. We recommend all Gateway v7 and v8.0 customers upgrade even if older versions of Swarm are still used. (CLOUD-3905)

• Optimized error handling for object retention updates. Upgrade to Swarm 16.1 if experiencing persistent 503 errors on some objects [ReaderNotFound7 ESR37]. (CLOUD-3916)

• Increase [storage_cluster] indexerMaxConnections (default 30) and indexerMaxConnectionsPerRoute (default 10) to allow more open connections to Elasticsearch nodes for listing and metering queries. Set to -1 to not change the default. (CLOUD-3983)

• Respond with an error instead of empty listing results when indexerHosts does not match the default Search Feed. (CLOUD-3219)

• Improved the audit logging of sub-requests of S3 DeleteObjects and CopyObject requests. The internal requests have the incoming request-id followed by -<count> or -copysource. (CLOUD-3951)

• Fixed the remaining Elasticsearch deprecation warnings triggered by some Portal metering queries:
  "date-interval-getter" - "[interval] on [date_histogram] is deprecated". (CLOUD-3909)

• Fixed an issue where Gateway 8.0 and later logs "S3ObjectRequestHandler: Unable to determine Veeam SOSAPI capacity.xml" with a NullPointerException if metering or quota is disabled. (CLOUD-3941)

• Fixed an S3 HEAD request of an object that could respond with a 500 Internal Error. It now responds with a 403 Forbidden like GET. (CLOUD-3987)
