* s3api: extend lifecycle XML types with NoncurrentVersionExpiration, AbortIncompleteMultipartUpload
Add missing S3 lifecycle rule types to the XML data model:
- NoncurrentVersionExpiration with NoncurrentDays and NewerNoncurrentVersions
- NoncurrentVersionTransition with NoncurrentDays and StorageClass
- AbortIncompleteMultipartUpload with DaysAfterInitiation
- Filter.ObjectSizeGreaterThan and ObjectSizeLessThan
- And.ObjectSizeGreaterThan and ObjectSizeLessThan
- Filter.UnmarshalXML to properly parse Tag, And, and size filter elements
Each new type follows the existing set-field pattern for conditional
XML marshaling. No behavior changes - these types are not yet wired
into handlers or the lifecycle worker.
* s3lifecycle: add lifecycle rule evaluator package
New package weed/s3api/s3lifecycle/ provides a pure-function lifecycle
rule evaluation engine. The evaluator accepts flattened Rule structs and
ObjectInfo metadata, and returns the appropriate Action.
Components:
- evaluator.go: Evaluate() for per-object actions with S3 priority
ordering (delete marker > noncurrent version > current expiration),
ShouldExpireNoncurrentVersion() with NewerNoncurrentVersions support,
EvaluateMPUAbort() for multipart upload rules
- filter.go: prefix, tag, and size-based filter matching
- tags.go: ExtractTags() extracts S3 tags from filer Extended metadata,
HasTagRules() for scan-time optimization
- version_time.go: GetVersionTimestamp() extracts timestamps from
SeaweedFS version IDs (both old and new format)
Comprehensive test coverage: 54 tests covering all action types,
filter combinations, edge cases, and version ID formats.
* s3api: add UnmarshalXML for Expiration, Transition, ExpireDeleteMarker
Add UnmarshalXML methods that set the internal 'set' flag during XML
parsing. Previously these flags were only set programmatically, causing
XML round-trip to drop elements. This ensures lifecycle configurations
stored as XML survive unmarshal/marshal cycles correctly.
Add comprehensive XML round-trip tests for all lifecycle rule types
including NoncurrentVersionExpiration, AbortIncompleteMultipartUpload,
Filter with Tag/And/size constraints, and a complete Terraform-style
lifecycle configuration.
* s3lifecycle: address review feedback
- Fix version_time.go overflow: guard timestampPart > MaxInt64 before
the inversion subtraction to prevent uint64 wrap
- Make all expiry checks inclusive (!now.Before instead of now.After)
so actions trigger at the exact scheduled instant
- Add NoncurrentIndex to ObjectInfo so Evaluate() can properly handle
NewerNoncurrentVersions via ShouldExpireNoncurrentVersion()
- Add test for high-bit overflow version ID
* s3lifecycle: guard ShouldExpireNoncurrentVersion against zero SuccessorModTime
Add early return when obj.IsLatest or obj.SuccessorModTime.IsZero()
to prevent premature expiration of versions with uninitialized
successor timestamps (zero value would compute to epoch, always expired).
