fix(s3tests): wire lifecycle worker for expiration suite (#9374)
* fix(s3tests): wire lifecycle worker for expiration suite
The upstream s3-tests `test_lifecycle_expiration` / `test_lifecyclev2_expiration`
exercise the "set rule, wait, verify deletion" path. Phase 4 (#9367) intentionally
stripped the PUT-time back-stamp, so pre-existing objects no longer pick up TtlSec
on a freshly-applied rule. The s3tests CI bare-bones `weed -s3` had nothing left
driving expiration.
Three changes that work together:
- Engine scales `Days` by `util.LifeCycleInterval`. Production keeps the 24h day;
the `s3tests` build tag shrinks it to 10s so a `Days: 1` rule completes inside
the suite's 30s polling window. Exported `DaysToDuration` so sibling-package
tests pin to the same scale.
- Scheduler/dispatcher tick defaults split into `_default` / `_s3tests` files.
Production stays 5s/30s/5m; the test build runs at 500ms/2s/2s so deletions
land within a couple ticks of becoming due.
- s3tests.yml spawns `weed shell s3.lifecycle.run-shard -shards 0-15 -events 0
-runtime 1800s` alongside the s3 server in both the basic and SQL blocks; the
shell command runs the full pipeline (reader + scheduler + dispatcher) for the
duration of the suite. `test_lifecycle_expiration_versioning_enabled` is left
out for now — versioned-bucket expiration via the worker still needs its own
pass.
Drive-by: bump `TestWorkerDefaultJobTypes` to 7 to match the registered
handler count (

feat(s3/lifecycle): wire AbortIncompleteMultipartUpload (Phase 5a) (#9368)
* feat(s3/lifecycle/router): emit ABORT_MPU events for .uploads/<id> init dirs Detect a meta-log event at exactly .uploads/<upload_id> (a directory) and build the ObjectInfo from its destination key (entry.Extended[key]) so a rule with Filter.Prefix=foo/ matches an MPU uploading to foo/bar. Sub-events under .uploads/<id>/<part> ride a different mtime and would over-fire the ABORT_MPU schedule, so they're rejected explicitly. m.ObjectKey stays as ev.Key (.uploads/<upload_id>) — the dispatcher needs the upload directory path, not the destination key, to actually remove the in-flight upload. * feat(s3api): wire LifecycleDelete ABORT_MPU to remove the upload dir Replaces the retryLater stub. Validates the .uploads/<upload_id> shape of req.ObjectPath (so a malformed event can't escalate to a wider rm), then deletes the upload directory under <bucket>/.uploads/<id>. Maps NotFound to NOOP_RESOLVED, transport errors to RETRY_LATER, success to DONE. * refactor(s3api): drop redundant exists check before lifecycle ABORT_MPU rm s3a.rm already does a NotFound-returning lookup, so the pre-check just adds a round-trip. Map filer_pb.ErrNotFound to NOOP_RESOLVED on rm, keep transport errors as RETRY_LATER. * refactor(s3/lifecycle/router): use s3_constants for MPU paths + Extended key Drop the hardcoded ".uploads/" and "key" string literals; the symbols already exist as s3_constants.MultipartUploadsFolder and ExtMultipartObjectKey, and the server side reaches them through the same constants. Keeping the test helpers tied to those names also makes the negative-result tests meaningful — they'd otherwise still pass if the lookup constant drifted. * fix(s3api): close lifecycle ABORT_MPU traversal + NOT_FOUND gaps Two issues with the recent ABORT_MPU plumbing: - "." and ".." passed the no-slash check but resolve to the bucket root via util.JoinPath, so .uploads/.. could rm the wrong directory. - filer.DeleteEntry suppresses ErrNotFound and returns success, so the rm path can't distinguish missing from deleted; the previous version reported DONE for an already-aborted upload instead of NOOP_RESOLVED. Reject the two reserved names explicitly and restore the existence pre-check so the outcome map stays correct. Add a table-test covering the rejected paths. * fix(s3/lifecycle/bootstrap): walk MPU init dirs by destination key A real MPU init record is a directory under .uploads/<id> created by mkdir; the bootstrap walker was skipping every directory entry, so an MPU that existed before the meta-log subscription was never aborted. Even with the skip relaxed, MatchPath used the .uploads/<id> path, so a rule with Filter.Prefix=logs/ would never fire on an MPU uploading to logs/foo.txt. Add Entry.DestKey, let IsMPUInit directories through, and use DestKey for both MatchPath and ObjectInfo.Key. A bare init directory with no DestKey means metadata hasn't landed yet — skip rather than guess. * fix(s3/lifecycle): gate (kind, info) shape so MPU init only fires ABORT_MPU An MPU init record carries IsMPUInit=true and IsLatest=false. Without gating, the router and bootstrap walker matched it against every active ActionKey for the bucket, so NONCURRENT_DAYS / NEWER_NONCURRENT fired (IsLatest=false reads as a noncurrent version). The dispatcher would then BLOCK on empty version_id and freeze the cursor. Add a shape gate at both call sites: - IsMPUInit + non-ABORT_MPU kind → continue - regular object + ABORT_MPU kind → continue Plus a defense-in-depth check at the top of EvaluateAction so future callers can't reintroduce the bug. Tests cover all three layers. * test(s3/lifecycle): tighten dual-action coverage at the call sites - Walk multi-action: replace the kinds-as-set check with an exact-shape DeepEqual on (path, kind) tuples. The set check would have missed an MPU init wrongly firing NONCURRENT_DAYS — exactly the regression the (kind, info) gate fixes. - Router: add a converse case for the dual ExpirationDays + AbortIncompleteMultipartUpload rule. A regular current-version object must fire only EXPIRATION_DAYS; without the gate the dispatcher would also receive ABORT_MPU and rm the object via the MPU code path. |

feat(s3/lifecycle): policy engine — XML conversion, Compile, decideMode, Match (#9348)
* feat(s3/lifecycle): XML lifecycle config to canonical Rule
LifecycleToCanonical takes a parsed *Lifecycle and returns
[]*s3lifecycle.Rule, the flat shape the engine compiles against.
Filter resolution mirrors AWS: <And> sub-elements (Prefix + Tags +
size filters) flatten into the canonical Rule's individual fields;
single <Tag> filter populates FilterTags with one entry; <Prefix>
filter takes precedence over the rule's top-level <Prefix>.
Multi-action rules (Expiration + NoncurrentVersion + AbortMPU on
the same XML <Rule>) populate every action field they declare.
RuleActionKinds expands the canonical rule into its compiled actions
downstream.
* feat(s3/lifecycle): engine snapshot skeleton + ActionKey type
Defines s3lifecycle.ActionKey{rule_hash, action_kind} as the engine's
primary identity, and adds the engine package's Snapshot type.
Snapshot is immutable after Compile (atomic-swapped on rebuild) and
holds the ActionKey-keyed routing indexes:
- originalDelayGroups: map[time.Duration][]ActionKey
- predicateActions: []ActionKey
- dateActions: map[ActionKey]time.Time
- actions: map[ActionKey]*CompiledAction
CompiledAction.engineState is an atomic.Uint32 so MarkActive (called
after the durable bootstrap_complete + mode write commits) is visible
to in-flight reader passes without a recompile. The reader filters on
IsActive() before dispatching, so stale-snapshot dispatches are
prevented.
No callers yet; downstream commits add Compile, decideMode, and the
Match functions.
* feat(s3/lifecycle): decideMode + retention gate
decideMode picks the scheduling mode for one (rule, kind) compiled
action. Disabled rule -> DISABLED; EXPIRATION_DATE -> SCAN_AT_DATE;
reader-driven kind whose eventLogHorizon + bootstrapLookbackMin
exceeds metaLogRetention -> SCAN_ONLY; otherwise EVENT_DRIVEN. The
gate runs per (rule, kind), so a 90d ExpirationDays sibling can
degrade to scan_only while its 7d AbortMPU sibling stays active.
MetaLogRetention=0 is treated as "unbounded" — matches the SeaweedFS
default (Phase 0 verified that meta-log files are written without
TtlSec by default), so the gate doesn't trip until an operator opts
in to volume-TTL pruning of /topics/.system/log/.
RuleMode is a Go-level enum here, separate from the wire-form
LifecycleState.RuleMode in the proto package; the worker maps between
them when reading/writing the durable state file.
* feat(s3/lifecycle): Compile builds the engine snapshot per-action
Compile produces a fresh Snapshot from per-bucket canonical rules.
Each input rule expands into N CompiledActions via RuleActionKinds;
mode comes from decideMode; activation requires both
bootstrap_complete (from PriorStates) and mode==EVENT_DRIVEN.
Routing indexes are populated by mode:
- SCAN_AT_DATE: always indexed in dateActions (detector schedules at
rule.date regardless of bootstrap status; the action runs once on
the date and is then done).
- EVENT_DRIVEN + active: indexed in originalDelayGroups (and in
predicateActions when the rule has tag/size filters).
- SCAN_ONLY / DISABLED / pending_bootstrap: not indexed; safety-scan
tick or operator action handle these.
snapshot_id is monotonic per process; pending writes stamp it. The
new snapshot replaces the engine's atomic pointer; in-flight reader
passes continue against their loaded snapshot.
Tests cover: single-action rule, multi-action expansion (one rule ->
three CompiledActions with three distinct delay groups), pending
bootstrap exclusion from indexes, retention gate, sibling actions
degrading independently under partial retention, ExpirationDate path,
disabled rule, MarkActive flipping IsActive(), Compile producing
monotonic snapshot ids.
* feat(s3/lifecycle): MatchOriginalWrite / MatchPredicateChange / MatchPath
The reader feeds events through the engine's match functions to find
the active ActionKeys whose filter applies. The minimal Event shape
the engine takes (bucket, path, tags, size, IsLatest, IsDeleteMarker,
IsMPUInit) keeps engine free of filer_pb dependencies; the reader
extracts these fields from the persisted *filer_pb.LogEntry payload
in Phase 3.
- MatchOriginalWrite: per-delay-group sweep entry. Filters on shape =
EventShapeOriginalWrite, prefix, tag, size, then per-kind shape
gating (ABORT_MPU only on IsMPUInit; EXPIRED_DELETE_MARKER only on
IsLatest+IsDeleteMarker).
- MatchPredicateChange: single near-now sweep. Returns only the
predicate-sensitive subset of active ActionKeys.
- MatchPath: bucket-level walker entry. Returns every active action
whose filter matches; bootstrap iterates these per object and calls
EvaluateAction per kind.
All filter on a.IsActive() at routing time so MarkActive flips become
visible without recompile.
* fix(s3/lifecycle): scope ActionKey by bucket; defensive copies; tidy compile
Three findings on the engine PR addressed:
1. Critical (cross-bucket collision): ActionKey was {RuleHash, ActionKind}
only. Two buckets with rules whose XML is identical produce the same
RuleHash; the second bucket's Compile would overwrite the first
bucket's CompiledAction in snap.actions. Add Bucket to ActionKey
so the engine's identity matches the on-disk path layout
/etc/s3/lifecycle/<bucket>/<rule_hash>/<action_kind>/. Regression
test pins it.
2. Major (immutability leak): OriginalDelayGroups, PredicateActions,
DateActions returned the snapshot's internal maps/slices by
reference, letting an external caller mutate routing state and
break the documented immutability contract. Return defensive
copies.
3. Minor (redundant condition): mode==EVENT_DRIVEN already implies
kind != EXPIRATION_DATE because decideMode routes the date kind
to SCAN_AT_DATE. Drop the redundant check.
Tests updated to construct ActionKey with the new Bucket field.
* fix(s3/lifecycle): drop size filters from rulePredicateSensitive
An object's size is immutable once written: any content change is a
fresh write that flows through the original-write stream, not the
predicate-change one. Tagging rules really can flip post-PUT
(operator adds/removes a tag without rewriting), so they belong; size
filters do not.
Including size filters here was adding rules to predicateActions for
no purpose — every predicate-change sweep would waste cycles
re-evaluating size predicates that physically can't have changed.
* perf(s3/lifecycle): pre-sort AllActions at Compile time
Snapshot is immutable after Compile (engineState bit-flips don't
change membership), so the (bucket, rule_hash, action_kind) ordering
is stable for the snapshot's lifetime. Build the sorted slice once
and serve every AllActions() call from it; drop the per-call
sort.Slice. The bootstrap walker is the primary caller and may
iterate this on every task entry.
* docs(s3/lifecycle): note the FilterSizeGreaterThan=0 ambiguity
Per AWS S3 spec, <ObjectSizeGreaterThan>0</ObjectSizeGreaterThan>
explicitly excludes 0-byte objects, but with the int64 zero value as
the unset sentinel we can't distinguish that from omitted-and-default.
Document the limitation inline so a future deployment that needs the
distinction can switch to *int64 (or a paired set-bool) and update
the matchers / RuleHash accordingly. Not fixing now: the explicit-zero
configuration is unusual, the canonical Rule shape mirrors the same
zero-as-unset convention as s3api.Filter, and a structural fix
touches every filter-using site (evaluator, due_at, match, RuleHash).
* fix(s3/lifecycle): make ObjectInfo.NoncurrentIndex *int
The previous int field had a zero-value collision: 0 is both "newest
non-current version" (a valid index) and "uninitialised by ObjectInfo{}
literal." A caller who built &ObjectInfo{IsLatest: false} without
explicitly setting NoncurrentIndex would have it implicitly read as
"newest non-current," and the count-based NewerNoncurrent retention
would use that bogus 0 to decide eligibility.
Switch to *int so nil is explicitly "not a non-current version /
index not yet computed." The evaluator's NoncurrentDays and
NewerNoncurrent paths conservatively return ActionNone when the
index is nil — the safety scan will revisit once the index is
supplied. This removes a class of latent footguns in test setup and
in any future code path that constructs ObjectInfo without a
versioning-aware builder.
idx() helper added in tests to keep the call sites a one-liner.
* refactor(s3/lifecycle): trim narration from engine + helpers
Drop "what" comments where well-named identifiers already say it
(IsActive, MarkActive, AllActions, etc.); collapse multi-paragraph
"why" docs to one-liners where the design rationale is already in
the design doc. Keep WHY comments only at non-obvious load-bearing
spots: the routing-index activation predicate, the *int rationale on
NoncurrentIndex, the field-tag namespace in RuleHash, the SmallDelay
horizon rule.
Files: action_kind.go, rule.go, rule_hash.go, evaluate.go, due_at.go,
min_trigger_age.go, event_log_horizon.go, engine/engine.go,
engine/compile.go, engine/match.go, engine/mode.go.
No behavior change; tests untouched and pass.
* fix(s3/lifecycle): durable PriorState.Mode wins over decideMode
PriorState.Mode was declared but never read; Compile recomputed mode
via decideMode and stored that on every CompiledAction. Effect: an
action durably persisted as SCAN_ONLY (lag fallback or operator
pause) or DISABLED would silently re-promote to EVENT_DRIVEN on the
next engine rebuild as soon as decideMode's XML+retention predicate
said so. Defeats the durability of mode state.
Use prior.Mode when set; fall through to decideMode only for new
actions (no prior at all) and for legacy entries persisted before
Mode existed (zero value). Regression test pins both branches.
* fix(s3/lifecycle): MarkActive routability — index every EVENT_DRIVEN key
MarkActive's documented contract was "flip visible without a
recompile," but the routing indexes (originalDelayGroups,
predicateActions) were only populated when active && mode ==
EVENT_DRIVEN at compile time. So a key compiled with
BootstrapComplete=false would never enter the indexes; a later
MarkActive flipped engineState but MatchOriginalWrite /
MatchPredicateChange iterated the indexes and never saw the key.
Only MatchPath (which walks bi.actionKeys) and DateActions worked.
Index every EVENT_DRIVEN key regardless of `active`. The runtime
IsActive() filter inside filterMatching already gates dispatch, so
inactive entries are matched-but-not-fired; flipping MarkActive
makes them routable without recompile, matching the documented
contract.
Tests updated: TestCompile_BootstrapPendingIndexedButInactive
asserts the indexed-but-inactive shape; TestMatchOriginalWrite_MarkActiveBecomesRoutable
asserts a MarkActive flip routes the next match.
* test(s3/lifecycle): pin nil NoncurrentIndex no-op behavior
Two regression tests for the *int pointer migration: nil index
combined with NewerNoncurrent (either paired with NoncurrentDays or
standalone) must short-circuit to ActionNone rather than guess at
the version's position in the keep-N window.
* refactor(s3/lifecycle): trim follow-up narration on engine + helpers
Comments accumulated since the last sweep — the durable-Mode rationale,
the MarkActive routability note, the routing-index doc, the
NoncurrentIndex pointer rationale, and the EvaluateAction docblock.
Trimmed each to one or two terse lines; the underlying contracts live
in the design doc.

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.
