docs(s3/lifecycle): event-driven redesign (#9346)
* docs(s3/lifecycle): event-driven redesign
Replaces the synchronous PUT-handler walk with an event-driven worker
model: meta-log reader subscribed to one filer, client-side heap merge
with per-filer-shard MessagePosition cursors, bucket-level bootstrap
with inline delete, blocked-cursor handling for fatal events, durable
retry budget for sustained-transient promotion, retention mode gate
that downgrades reader-driven rules to scan_only when log retention
falls below the rule's event-log horizon.
* docs(s3/lifecycle): record Phase 0 verified assumptions
ReadPersistedLogBuffer payload carries Extended (event marshaled via
SubscribeMetadataResponse → ToProtoEntry). Meta-log files at
topics/.system/log/<date>/<HH-MM>.<filerId> are written without TtlSec
in filer_notify_append.go; retention is unbounded by default and only
shrinks if an operator sets a filer.conf rule with a TTL on the
SystemLogDir prefix. .versions/ filenames are v_<16h-ts><16h-rand>
with old/new (inverted) format distinguished by threshold
0x4000000000000000; getVersionTimestamp / compareVersionIds give
format-agnostic ordering for successor-version discovery.
* feat(s3/lifecycle): rule evaluator and dueAt helper
Evaluate(rule, info, now) returns the EvalResult by object shape:
IsMPUInit -> AbortMultipartUpload, IsDeleteMarker -> ExpireDeleteMarker
when sole survivor, IsLatest -> DeleteObject (Days or Date), non-current
-> DeleteVersion (Days fallback to ModTime when SuccessorModTime is
zero; NewerNoncurrent retention enforced when both are set).
ComputeDueAt mirrors Evaluate's shape and returns the earliest eligible
wall-clock time for the same (rule, info), used by the reader/bootstrap
to decide pending vs inline-delete.
Adds StatusEnabled/Disabled and SmallDelay consts and an IsMPUInit
flag on ObjectInfo so .uploads/<id>/ entries route to AbortMPU without
overloading IsLatest.
No callers; package compiles standalone.
* feat(s3/lifecycle): MinTriggerAge for safety-scan cadence
Returns the smallest non-zero day threshold across the rule's actions.
Used as max(MinTriggerAge, kindFloor) for the per-kind cadence; date,
count-only, and delete-marker-only rules return 0 so callers fall
through to their kind-specific floor.
* feat(s3/lifecycle): EventLogHorizon for retention mode gate
Returns the maximum event age the reader needs for a rule. Days-based
kinds return their day threshold; pure NewerNoncurrent (count) and
ExpiredObjectDeleteMarker return SmallDelay. Date rules return 0 (the
gate skips them). Multi-action rules take the max — strictest horizon
wins.
Drives the Phase 2 mode gate: metaLogRetention < EventLogHorizon(rule)
+ bootstrapLookbackMin -> scan_only with RETENTION_BELOW_HORIZON.
* feat(s3/lifecycle): RuleHash for per-rule state CAS
sha256 over canonicalized form, first 8 bytes. Stable across tag-key
reorder, prefix trailing-slash variation, ID renames, and Status flips
(state continuity is preserved when an operator toggles
Enabled/Disabled). Different action shapes — different days, filter,
or action type — hash differently.
Used by the per-rule state directory layout
/etc/s3/lifecycle/<bucket>/<rule_hash_hex>/ and by the bootstrap
detector's reconcile-on-PUT.
* feat(s3/lifecycle): add s3_lifecycle.proto storage schema
Defines the durable types backing the lifecycle worker:
LifecycleState (per-rule mode + bootstrap_complete + degraded_reason
incl. RETENTION_BELOW_HORIZON / LOST_LOG), PendingItem, EntryIdentity,
BootstrapState, ReaderState (per-filer-shard cursors plus
tail_drained_streams marker), BlockerRecord (rule_hash optional for
pre-evaluation failures), RetryBudgetEntry with the four-shape
StreamKey oneof, and RetryTarget (no action / no expected_identity —
retry replays handler against current state).
No callers; schema only. Wired into the pb Makefile.
* feat(s3/lifecycle): add S3LifecycleParams to TaskParams
Wires lifecycle subroutines into the existing worker dispatch.
Subtype is READ (cluster-singleton meta-log reader), BOOTSTRAP
(per-bucket walker), or DRAIN (per-rule pending). bucket / rule_hash
populated for the latter two; ContinuationHint is an advisory resume
point for kill-resumable BOOTSTRAP / READ.
oneof tag = 14, after the existing ec_balance_params at 13.
* fix(s3/lifecycle): noncurrent delete markers honor NoncurrentDays
A non-current delete marker is just another version per AWS S3 spec
and is eligible under NoncurrentVersionExpirationDays. The
IsDeleteMarker special case is meant only for the *current* delete
marker (sole-survivor ExpiredObjectDeleteMarker action), so guard
that switch arm with IsLatest. Without IsLatest, the bootstrap walker
silently skipped pre-existing non-current delete markers under a
NoncurrentDays rule because ComputeDueAt returned zero.
Mirrors the same fix in evaluate.go so the runtime decision matches.
* fix(s3/lifecycle): preserve prefix trailing slash in RuleHash
"logs" and "logs/" match different object sets under literal
strings.HasPrefix semantics: "logs" matches "logsmore/x", "logs/" does
not. Collapsing them in the hash would let an XML edit silently bind
the new rule to the previous rule's durable state directory, causing
stale bootstrap_complete and stale pending entries against a rule
that now matches a different set.
* fix(s3/lifecycle): add UNSPECIFIED sentinels to enum zero values
Proto3 best practice: enum 0 should be an _UNSPECIFIED sentinel, not
an active value. Persisted state schemas care most: a partially
populated payload (or one written by an older binary that didn't set
the field) would otherwise silently default to a semantically active
value.
- LifecycleState.RuleKind: shifts EXPIRATION_DAYS..EXPIRED_DELETE_MARKER
from 0..5 to 1..6, with RULE_KIND_UNSPECIFIED at 0.
- LifecycleState.RuleMode: shifts EVENT_DRIVEN..PENDING_BOOTSTRAP from
0..4 to 1..5.
- LifecycleState.DegradedReason: replaces NONE=0 with
DEGRADED_REASON_UNSPECIFIED=0 (operators treat both as healthy).
- StreamKind: shifts ORIGINAL..PENDING from 0..3 to 1..4.
- S3LifecycleParams.Subtype: shifts READ..DRAIN from 0..2 to 1..3, so
an unset subtype no longer routes into the cluster-singleton READ task.
No on-disk state has been written yet; renumbering is safe.
* docs(s3/lifecycle): per-action state, not per-rule
A single AWS lifecycle XML <Rule> can declare multiple actions in
parallel (e.g. ExpirationDays=90 + AbortMPU=7 + NoncurrentDays=30).
Each must drive its own delay/horizon/mode/pending stream
independently. Modeling the rule as one compiled entry with one kind
collapses these — picking the smallest delay (7d MPU) means the 90d
expiration cursor advances past objects that aren't yet due, and the
90d action never re-fires.
Restructure storage to per-action: every XML rule expands into N
compiled actions; state lives at <bucket>/<rule_hash>/<action_kind>/.
The intermediate rule_hash directory keeps a rule's actions grouped
for operator listing. Each action has its own state file with its own
mode + bootstrap_complete + degraded_reason; sibling actions of the
same rule can degrade independently.
* fix(s3/lifecycle): per-action proto schema + safety-scan counters
Realigns the durable schema with the per-action storage model and the
safety-scan contract in the design doc.
- Promote LifecycleState.RuleKind to a top-level ActionKind enum and
rename rule_kind -> action_kind. The same enum now also keys
BootstrapKey, PendingKey, and BlockerRecord so per-action streams
under one rule never collapse.
- LifecycleState now keyed by (rule_hash, action_kind). Added
last_safety_scan_ts_ns / next_safety_scan_ts_ns and the four
observability counters the design specifies (evaluated_total,
expired_total, metadata_only_total, error_total). Dropped
last_evaluated_ns, deleted_total, skipped_object_lock_total, and
pending_size — subsumed or out-of-band.
- BlockerRecord.action_kind is OPTIONAL (UNSPECIFIED for
pre-evaluation failures, just like rule_hash).
No on-disk state has been written yet; the renumbering / rename is
free.
* fix(s3/lifecycle): per-action MinTriggerAge / EventLogHorizon helpers
The retention mode gate and safety-scan cadence run on each compiled
action independently. Taking a "min/max across all actions in the
rule" — as the previous helpers did — was wrong: a 90d ExpirationDays
sibling alongside a 7d AbortMPU action would cause the 90d cursor to
advance at 7d (because MinTriggerAge picked the smallest), and the
ExpirationDays action would never re-fire on objects that aged past
the 7d sweep window before reaching 90d.
Both helpers now take an ActionKind and return the threshold for that
specific action only. Returns 0 if the rule does not declare the
requested kind, which makes the gate a no-op and the cadence fall
through to the kind floor.
Also adds RuleActionKinds(rule), the canonical expansion that the
engine uses at compile time to turn one XML rule into N compiled
actions. NewerNoncurrentVersions paired with NoncurrentDays is
subsumed into a single NONCURRENT_DAYS action (AWS-paired
conditions); only when NewerNoncurrent stands alone does it become
NEWER_NONCURRENT.
* fix(s3/lifecycle): length-prefix RuleHash to remove delimiter ambiguity
The previous encoding used "tag=K=V\n" lines, which is ambiguous: a
tag (a=b, c) serializes identically to (a, b=c). A prefix containing
"\nexp_days=99" could likewise forge an action field. Either could
silently bind two semantically different rules to the same per-rule
state directory.
Switch to a length-prefixed canonical form: each scalar is written as
<field-tag-byte> <uvarint-length> <bytes>. Field-tag bytes namespace
each scalar so ("a=b" tag-key) and ("a" tag-key with "=b" leakage)
can't collide. Three regression tests pin the resistance.
* docs(s3/lifecycle): ActionKey is the engine identity, not rule_hash
Finishes the per-action restructure across the engine pseudocode,
bootstrap completion, drain locks, detector paths, policy CAS, and
Phase 2 plan. Every per-action data structure — engine indexes,
target modes, newly-completed sets, bootstrap completion bits, drain
keys, locks, metrics, status — is now keyed by
ActionKey{rule_hash, action_kind}, not by rule_hash alone.
Without this, sibling actions under one XML rule still shared
scheduling state in the engine: originalDelayGroups holding
[]ruleHash means a rule's 7d AbortMPU and 90d ExpirationDays
collapse into one entry, the smaller delay wins for cursor advance,
and the larger sibling never re-fires.
Helper API tightened: EvaluateAction(rule, kind, info, now) and
ComputeDueAt(rule, kind, info) replace the aggregate-rule signatures
so a caller asks one specific action's eligibility against one
entry, never "any action of this rule." Drain task lock includes
action_kind so siblings have independent re-arm timers. Policy CAS
moves from rule_hash to ActionKey membership.
* fix(s3/lifecycle): kind-aware EvaluateAction / ComputeDueAt
Replaces the aggregate-rule signatures with per-action ones:
EvaluateAction(rule, kind, info, now) and ComputeDueAt(rule, kind,
info). The old Evaluate(rule, info, now) could return the verdict of
ANY action declared on the rule, which sat wrong with the per-action
engine indexing (each ActionKey has its own delay group, mode, and
pending stream).
Each helper now decides exactly one (rule, kind) compiled action's
fate against one entry. Asking for a kind the rule doesn't declare,
or asking against the wrong object shape for that kind, returns
ActionNone / zero — never silently routes to a sibling.
Multi-action regression test: a rule with ExpirationDays=90 and
AbortMPU=7 evaluates each kind independently for the same entry; the
7d window has no influence on the 90d eligibility decision.

chore: remove ~50k lines of unreachable dead code (#8913)
* chore: remove unreachable dead code across the codebase Remove ~50,000 lines of unreachable code identified by static analysis. Major removals: - weed/filer/redis_lua: entire unused Redis Lua filer store implementation - weed/wdclient/net2, resource_pool: unused connection/resource pool packages - weed/plugin/worker/lifecycle: unused lifecycle plugin worker - weed/s3api: unused S3 policy templates, presigned URL IAM, streaming copy, multipart IAM, key rotation, and various SSE helper functions - weed/mq/kafka: unused partition mapping, compression, schema, and protocol functions - weed/mq/offset: unused SQL storage and migration code - weed/worker: unused registry, task, and monitoring functions - weed/query: unused SQL engine, parquet scanner, and type functions - weed/shell: unused EC proportional rebalance functions - weed/storage/erasure_coding/distribution: unused distribution analysis functions - Individual unreachable functions removed from 150+ files across admin, credential, filer, iam, kms, mount, mq, operation, pb, s3api, server, shell, storage, topology, and util packages * fix(s3): reset shared memory store in IAM test to prevent flaky failure TestLoadIAMManagerFromConfig_EmptyConfigWithFallbackKey was flaky because the MemoryStore credential backend is a singleton registered via init(). Earlier tests that create anonymous identities pollute the shared store, causing LookupAnonymous() to unexpectedly return true. Fix by calling Reset() on the memory store before the test runs. * style: run gofmt on changed files * fix: restore KMS functions used by integration tests * fix(plugin): prevent panic on send to closed worker session channel The Plugin.sendToWorker method could panic with "send on closed channel" when a worker disconnected while a message was being sent. The race was between streamSession.close() closing the outgoing channel and sendToWorker writing to it concurrently. Add a done channel to streamSession that is closed before the outgoing channel, and check it in sendToWorker's select to safely detect closed sessions without panicking. |

lifecycle worker: drive MPU abort from lifecycle rules (#8812)
* lifecycle worker: drive MPU abort from lifecycle rules Update the multipart upload abort phase to read AbortIncompleteMultipartUpload.DaysAfterInitiation from the parsed lifecycle rules. Falls back to the worker config abort_mpu_days when no lifecycle XML rule specifies the value. This means per-bucket MPU abort thresholds are now respected when set via PutBucketLifecycleConfiguration, instead of using a single global worker config value for all buckets. * lifecycle worker: only use config AbortMPUDays when no lifecycle XML exists When a bucket has lifecycle XML (useRuleEval=true) but no AbortIncompleteMultipartUpload rule, mpuAbortDays should be 0 (no abort), not the worker config default. The config fallback should only apply to buckets without lifecycle XML. * lifecycle worker: only skip .uploads at bucket root * lifecycle worker: use per-upload rule evaluation for MPU abort Replace the single bucket-wide mpuAbortDays with per-upload evaluation using s3lifecycle.EvaluateMPUAbort, which respects each rule's prefix filter and DaysAfterInitiation threshold. Previously the code took the first enabled abort rule's days value and applied it to all uploads, ignoring prefix scoping and multiple rules with different thresholds. Config fallback (abort_mpu_days) now only applies when lifecycle XML is truly absent (xmlPresent=false), not when XML exists but has no abort rules. Also fix EvaluateMPUAbort to use expectedExpiryTime for midnight-UTC semantics matching other lifecycle cutoffs. --------- Co-authored-by: Copilot <copilot@github.com> |

lifecycle worker: fix ExpiredObjectDeleteMarker to match AWS semantics (#8811)
* lifecycle worker: add NoncurrentVersionExpiration support Add version-aware scanning to the rule-based execution path. When the walker encounters a .versions directory, processVersionsDirectory(): - Lists all version entries (v_<versionId>) - Sorts by version timestamp (newest first) - Walks non-current versions with ShouldExpireNoncurrentVersion() which handles both NoncurrentDays and NewerNoncurrentVersions - Extracts successor time from version IDs (both old/new format) - Skips delete markers in noncurrent version counting - Falls back to entry Mtime when version ID timestamp is unavailable Helper functions: - sortVersionsByTimestamp: insertion sort by version ID timestamp - getEntryVersionTimestamp: extracts timestamp with Mtime fallback * lifecycle worker: address review feedback for noncurrent versions - Use sentinel errLimitReached in versions directory handler - Set NoncurrentIndex on ObjectInfo for proper NewerNoncurrentVersions evaluation * lifecycle worker: fail closed on XML parse error, guard zero Mtime - Fail closed when lifecycle XML exists but fails to parse, instead of falling back to TTL which could apply broader rules - Guard Mtime > 0 before using time.Unix(mtime, 0) to avoid mapping unset Mtime to 1970, which would misorder versions and cause premature expiration * lifecycle worker: count delete markers toward NoncurrentIndex Noncurrent delete markers should count toward the NewerNoncurrentVersions retention threshold so data versions get the correct position index. Previously, skipping delete markers without incrementing the index could retain too many versions after delete/recreate cycles. * lifecycle worker: fix version ordering, error propagation, and fail-closed scope 1. Use full version ID comparison (CompareVersionIds) for sorting .versions entries, not just decoded timestamps. Two versions with the same timestamp prefix but different random suffixes were previously misordered, potentially treating the newest version as noncurrent and deleting it. 2. Propagate .versions listing failures to the caller instead of swallowing them with (nil, 0). Transient filer errors on a .versions directory now surface in the job result. 3. Narrow the fail-closed path to only malformed lifecycle XML (errMalformedLifecycleXML). Transient filer LookupEntry errors now fall back to TTL with a warning, matching the original intent of "fail closed on bad config, not on network blips." * lifecycle worker: only skip .uploads at bucket root * lifecycle worker: sort.Slice, mixed-format test, XML presence tracking - Replace manual insertion sort with sort.Slice in sortVersionsByVersionId - Add TestCompareVersionIdsMixedFormats covering old/new format ordering - Distinguish "no lifecycle XML" (nil) from "XML present but no effective rules" (non-nil empty slice) so buckets with all-disabled rules don't incorrectly fall back to filer.conf TTL expiration * lifecycle worker: guard nil Attributes, use TrimSuffix in test - Guard entry.Attributes != nil before accessing GetFileSize() and Mtime in both listExpiredObjectsByRules and processVersionsDirectory - Use strings.TrimPrefix/TrimSuffix in TestVersionsDirectoryNaming to match the production code pattern * lifecycle worker: skip TTL scan when XML present, fix test assertions - When lifecycle XML is present but has no effective rules, skip object scanning entirely instead of falling back to TTL path - Test sort output against concrete expected names instead of re-using the same comparator as the sort itself * lifecycle worker: fix ExpiredObjectDeleteMarker to match AWS semantics Rewrite cleanupDeleteMarkers() to only remove delete markers that are the sole remaining version of an object. Previously, delete markers were removed unconditionally which could resurface older versions in versioned buckets. New algorithm: 1. Walk bucket tree looking for .versions directories 2. Check ExtLatestVersionIsDeleteMarker from directory metadata 3. Count versions in the .versions directory 4. Only remove if count == 1 (delete marker is sole version) 5. Require an ExpiredObjectDeleteMarker=true rule (when lifecycle XML rules are present) 6. Remove the empty .versions directory after cleanup This phase runs after NoncurrentVersionExpiration so version counts are accurate. * lifecycle worker: respect prefix filter in ExpiredObjectDeleteMarker rules Previously hasDeleteMarkerRule was a bucket-wide boolean that ignored rule prefixes. A prefix-scoped rule like "logs/" would incorrectly clean up delete markers in all paths. Add matchesDeleteMarkerRule() that checks if a matching enabled ExpiredObjectDeleteMarker rule exists for the specific object key, respecting the rule's prefix filter. Falls back to legacy behavior (allow cleanup) when no lifecycle XML rules are provided. * lifecycle worker: only skip .uploads at bucket root Check dir == bucketPath before skipping directories named .uploads. Previously a user-created directory like data/.uploads/ at any depth would be incorrectly skipped during lifecycle scanning. * lifecycle worker: fix delete marker cleanup with XML-present empty rules 1. matchesDeleteMarkerRule now uses nil check (not len==0) for legacy fallback. A non-nil empty slice means lifecycle XML was present but had no ExpiredObjectDeleteMarker rules, so cleanup is blocked. Previously, an empty slice triggered the legacy true path. 2. Use per-directory removedHere flag instead of cumulative cleaned counter when deciding to remove .versions directories. Previously, after the first successful cleanup anywhere in the bucket, every subsequent .versions directory would be removed even if its own delete marker was not actually deleted. * lifecycle worker: use full filter matching for delete marker rules matchesDeleteMarkerRule now uses s3lifecycle.MatchesFilter (exported) instead of prefix-only matching. This ensures tag and size filters on ExpiredObjectDeleteMarker rules are respected, preventing broader deletions than the configured policy intends. Add TestMatchesDeleteMarkerRule covering: nil rules (legacy), empty rules (XML present), prefix match/mismatch, disabled rules, rules without the flag, and tag-filtered rules against tagless markers. --------- Co-authored-by: Copilot <copilot@github.com> |

s3lifecycle: add lifecycle rule evaluator package and extend XML types (#8807)
* 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). --------- Co-authored-by: Copilot <copilot@github.com> |
