Chris Lu af2a359e45 feat(s3/lifecycle): metadata_only_total Prometheus counter (#9399)
Operator-visible signal for the metadata-only delete path landed in
PR 9390. Increment seaweedfs_s3_lifecycle_metadata_only_total{bucket,
rule_hash} after each successful unversioned or noncurrent / expired-
marker delete that took the skip-chunk path. Suspended-versioning
null delete is intentionally not counted: that path's nil err can
mean "deleted" or "NotFound", so a count there would over-report.
rule_hash is hex-encoded for label safety; nil bytes collapse to
"". DeleteBucketMetrics tears the new series down alongside the
existing lifecycle counters when a bucket is removed.

Chris Lu bb0c7c779f feat(s3/lifecycle): metadata-only delete when entry TtlSec > 0 (Phase 2b) (#9390)
* refactor(s3): thread metadataOnly into delete helpers

Add a metadataOnly bool to deleteUnversionedObjectWithClient and
deleteSpecificObjectVersion. When true the helper sends IsDeleteData=
false to the filer's DeleteEntry RPC so per-chunk DeleteFile RPCs are
skipped — the volume server reclaims chunks on its own at TTL drop.
Non-lifecycle callers (DELETE handlers, batch delete) pass false to
preserve today's eager-chunk-delete behavior; only the lifecycle
handler in the next commit will pass true.

* feat(s3/lifecycle): metadata-only delete when entry TtlSec > 0

Per-write TTL stamping (PR 9377) sets Attributes.TtlSec on every
lifecycle-fitting entry. When the live entry the LifecycleDelete
handler fetched carries TtlSec > 0 the volume server is guaranteed
to reclaim chunks at TTL drop, so the filer can skip per-chunk
DeleteFile RPCs and just remove the entry record. lifecycleDispatch
now computes metadataOnly from the live entry and threads it through
the unversioned, suspended-null, and noncurrent/expired-marker delete
paths. createDeleteMarker is unaffected — it creates a marker, never
deletes chunks.

Chris Lu c6ad6dcf74 feat(s3/lifecycle): sole-survivor delete-marker routing (Phase 5b/2) (#9381)
* feat(s3/lifecycle): sole-survivor delete-marker routing (Phase 5b/2)

Production stores delete markers under <object>.versions/<version-file>;
buildObjectInfo skips every version-folder event because it can't tell
current from noncurrent without sibling state. EXP_DM is the one rule
that can be routed from the file path alone: if the marker is the only
entry under .versions/<key>/ then it's necessarily the latest.

Add SiblingLister; gate the listing on (versioned, version-folder path,
delete-marker entry, EXP_DM rule active for the bucket, lister supplied)
so non-marker version writes pay nothing. The Match carries the LOGICAL
key in ObjectKey and the marker's version_id in VersionID so the
dispatcher can reach deleteSpecificObjectVersion(bucket, logical, vid);
without a version_id the dispatcher would BLOCK and freeze the cursor.

Server-side dispatch re-checks sole-survivor before deleting: another
PUT can land between schedule and dispatch, and identity-CAS only covers
the marker entry, not the directory shape. Lists .versions/<key>/ with
limit 2 and returns NOOP_RESOLVED if count != 1 or the surviving entry
is not the same version.

Fix isDeleteMarkerEntry to compare string(v) == "true" — production
writes []byte("true"), not {1}; every other reader of ExtDeleteMarkerKey
in this repo uses the string predicate.

filerSiblingLister.Count caps at limit 2 — callers only distinguish
"sole survivor" (1) from "more than one" (>=2).

Follows #9373.

* fix(s3/lifecycle): gate sibling listing on active event-driven EXP_DM

hasActionKind tested key presence only; an EXP_DM rule whose action was
inactive (BootstrapComplete=false) or scan-only would still trigger the
sibling-listing RPC even though no match could fire. Replace with a
helper that mirrors the per-key filter Route already applies before
emitting matches: kind matches, snap.Action returns non-nil, IsActive,
and Mode == ModeEventDriven.

Add a regression test that builds a versioned snapshot with the rule
but no PriorStates (action stays inactive) and asserts the lister is
never consulted.

* chore(s3/lifecycle): trim verbose comments

* fix(s3/lifecycle): null version, hard-delete trigger, latest pointer

Three correctness gaps in EXP_DM routing.

1. Null version. SiblingLister.Count saw only .versions/<key>/, but a
   pre-versioning bare-key object survives outside that folder when
   versioning is enabled later. Marker + null would look like count==1
   and EXP_DM would re-expose the old object. Replace Count with
   Survivors which also reports HasNullVersion; route- and dispatch-time
   suppress when set.

2. Hard-delete trigger. The router skipped events with NewEntry==nil so
   a noncurrent hard-delete that left the marker as sole survivor never
   fired EXP_DM. Allow version-folder hard-deletes through; the lister's
   LoneEntry carries the surviving marker's version_id and identity.

3. Latest pointer. checkSoleSurvivorMarker only checked count and
   filename. The worker can race createDeleteMarker between the file
   write and the .versions/ directory metadata update. Require
   ExtLatestVersionIdKey == versionId; missing pointer returns
   retry-later instead of deleting.

Adds a null-version exists check on the dispatch path too.

* fix(s3/lifecycle): normalize null-version lookup errors and detect dir markers

Two correctness bugs in the null-version check.

Route-side: filerSiblingLister called client.LookupDirectoryEntry
directly. SeaweedList wraps not-found via filer_pb.LookupEntry, which
normalizes the gRPC string-mapped not-found into ErrNotFound. The raw
client returns it as a generic error instead, so every absent
null-version (the common case) bubbled up as an error and the router
suppressed every otherwise-valid match. Use filer_pb.LookupEntry.

Both sides: explicit S3 directory-key markers (object names ending in /)
are stored as directory entries with Attributes.Mime set;
processExplicitDirectory in the listing path treats them as null
versions. The previous check was !IsDirectory only, which let the
marker delete proceed and re-expose the directory key. Add
IsDirectoryKeyObject() to both predicates. Also use
util.NewFullPath(...).DirAndName() for the parent/name split so a
trailing-slash key resolves to the same underlying entry path as the
listing code.

* fix(s3/lifecycle): EXP_DM ctx propagation, nil-entry guard, fast-path skip

Three small follow-ups on the EXP_DM dispatch path.

checkSoleSurvivorMarker now takes ctx instead of context.Background()
so worker shutdown / deadlines cancel the SeaweedList RPC instead of
stalling.

If SeaweedList fires the lone callback with entry==nil, firstName
stays empty and the marker-replaced check would short-circuit; that's
the one shape that bypasses the dispatch guard, so retry-later instead.

routeSoleSurvivorMarker now skips the Survivors RPC on regular
non-marker version creates — those always have Count >= 2, so the
listing was wasted load on every versioned write under an EXP_DM rule.
Hard-delete events (NewEntry==nil) and marker creates still flow
through. Added a regression test asserting the regular-create case
doesn't consult the lister.

Documented that logicalKeyFromVersionPath rejects bucket-root markers
intentionally.

Chris Lu 159cfc97ce feat(s3/lifecycle): classify versioned events by storage path (Phase 5b/1) (#9373)
* feat(s3/lifecycle/router): classify versioned events by storage path

Phase 5b first slice. Pass the bucket's Versioned flag from the engine
snapshot into buildObjectInfo and:

- Recognize <key>.versions/<vid> events as noncurrent versions.
  IsLatest=false, info.Key strips the .versions/<vid> suffix so a
  rule's Filter.Prefix matches the user's logical key, and the
  AWS-visible version_id rides on Match.VersionID for the dispatcher
  to target a single version on the server.
- Read IsDeleteMarker from Extended unconditionally — the engine
  rejects ExpiredObjectDeleteMarker when NumVersions != 1, so without
  sibling listing the marker case stays correctly suppressed (a
  separate PR will add the listing).
- Non-versioned buckets keep the existing behavior even when an
  object literally named "*.versions/v1" exists; Versioned=false
  short-circuits the path classification.

Time-based NoncurrentDays now fires on noncurrent events.
NewerNoncurrent and ExpiredObjectDeleteMarker still need sibling
listing — left for a follow-up.

* fix(s3/lifecycle/router): require ExtVersionIdKey to confirm noncurrent

Path classification alone misclassifies a literal-key collision: a
versioned bucket holding an object with key "logs/backup.versions/2023"
would be flagged noncurrent and have its key stripped to "logs/backup",
losing the user's actual rule-prefix-matching path. SeaweedFS doesn't
reserve the .versions/ segment, so the path shape is necessary but
not sufficient.

Add an authoritative confirmation: the entry must declare the same
version_id via ExtVersionIdKey (the field SeaweedFS sets when storing
a tracked version). Also reject idx==0 paths so ".versions/<vid>"
can't yield an empty logical key.

Tests:
- collision: versioned bucket + .versions/ in literal key + no
  metadata (and the mismatched-vid variant) → still classified as a
  current-version object;
- root-versions: .versions/v1 (idx==0) → treated as a regular key;
- existing noncurrent test now sets ExtVersionIdKey to mirror the
  storage shape.

* fix(s3/lifecycle/router): skip versioned-bucket version-folder events

The previous attempt tried to classify <key>.versions/<vid> events as
noncurrent versions by storage path. That's broken on three counts:

- SeaweedFS stores version files as v_<id> (getVersionFileName), so
  comparing the path suffix to the raw ExtVersionIdKey never matches.
- The "current latest" version on a versioned bucket lives at the
  same .versions/v_<id> path shape as noncurrent versions; the latest
  pointer is on the parent .versions/ directory's
  Extended[ExtLatestVersionIdKey], which the router doesn't see.
- Even with a correct vid match, IsLatest=false plus the storage path
  as ObjectKey would have the dispatcher recompose <storagepath>.versions/v_<id>
  and no-op (or worse, target the wrong file).

Until we route from .versions/ directory pointer-transition events
(or supply IsLatest/SuccessorModTime/index from sibling listing),
skip every event under a *.versions/ folder. Bare-key events (null
versions) still route normally; bootstrap walking covers the
versioned-storage cases.

Tests assert the skip across tracked, literal-collision, and
bucket-root .versions paths.

* feat(s3api): refuse noncurrent-kind delete on the current latest version

Defense-in-depth for the noncurrent kinds: even when bootstrap (or a
future event-driven path) thinks a version is noncurrent, the server
must verify against the .versions/ directory's
Extended[ExtLatestVersionIdKey] before deleting. If the target version
matches the latest pointer the action is silently dropped as
NOOP_RESOLVED:VERSION_IS_LATEST instead of deleting the live data.

* refactor(s3/lifecycle): tidy versioning gates per review

- router: skip directory entries (other than MPU init) in
  buildObjectInfo so .versions/ folder events never become
  ObjectInfo. Subtest "versions dir itself" added.
- s3api: switch isCurrentLatestVersion's path split from
  filepath.Split (OS-dependent) to path.Split so filer paths
  always use '/'.

Chris Lu 89aab30821 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.

Chris Lu 85abf3ca88 feat(shell): s3.lifecycle.run-shard + integration test (#9361)
* feat(shell): s3.lifecycle.run-shard for manual Phase 3 dispatch

Subscribes to the filer meta-log filtered to one (bucket, key-prefix-hash)
shard, routes events through the compiled lifecycle engine, and dispatches
due actions to the S3 server's LifecycleDelete RPC. Persists the per-shard
cursor to /etc/s3/lifecycle/cursors/shard-NN.json so subsequent runs resume.

Operator-runnable harness for end-to-end Phase 3 validation while the
plugin-worker auto-scheduler is still pending. EventBudget bounds a single
invocation; flags expose dispatch + checkpoint cadence.

Discovers buckets by walking the configured DirBuckets path and reading
each bucket entry's Extended[s3-bucket-lifecycle-configuration-xml]
through lifecycle_xml.ParseCanonical. All compiled actions are seeded
BootstrapComplete=true so the run dispatches whatever fires immediately;
production bootstrap walks set this incrementally per bucket.

* test(s3/lifecycle): integration test driving the run-shard shell command

Spins up 'weed mini', creates a bucket with a 1-day expiration on a prefix,
PUTs the target object, then rewrites the entry's Mtime via filer
UpdateEntry to 30 days ago. Runs 's3.lifecycle.run-shard' for every
shard via 'weed shell' subprocess and asserts the backdated object is
deleted within 30s, and the in-prefix-but-recent object remains.

The S3 API rejects Expiration.Days < 1, so 'wait a day' is unworkable.
Backdating via the filer's gRPC sidesteps that constraint while still
exercising the real Reader -> Router -> Schedule -> Dispatcher ->
LifecycleDelete RPC path end-to-end.

Wires a new s3-lifecycle-tests job into s3-go-tests.yml. The test runs
all 16 shards because ShardID(bucket, key) is hash-based and the test
shouldn't couple to that detail; running every shard keeps the test
independent of the hash function.

* fix(shell/s3.lifecycle.run-shard): address review findings

- Reject negative -events explicitly. Help text already defines 0 as
  unbounded; negative budgets created ambiguous behavior in pipeline.Run.
- Bound the gRPC dial with a 30s timeout instead of context.Background()
  so an unreachable S3 endpoint doesn't hang the shell.
- Paginate the bucket listing in loadLifecycleCompileInputs. SeaweedList
  takes a single-RPC limit; the prior 4096 silently dropped buckets
  past that page on large clusters. Loop with startFrom until a page
  comes back short.
- Surface parse errors instead of swallowing them. Buckets with
  malformed lifecycle XML now print the first three errors verbatim
  and a count for the rest, so an operator running this command for
  diagnostics can find what's wrong.

* feat(shell/s3.lifecycle.run-shard): -shards range/set with one subscription

Adds -shards "lo-hi" or "a,b,c" to the manual run command and threads
the same model through Reader and Pipeline.

- reader.Reader gains ShardPredicate (func(int) bool) and StartTsNs;
  ShardID stays for the single-shard short form. Event carries the
  computed ShardID so consumers can route per-shard without rehashing.
- dispatcher.Pipeline gains Shards []int. When set, Run holds one
  Cursor + Schedule + Dispatcher per shard, opens one filer
  SubscribeMetadata stream with a predicate covering the whole set,
  and routes events into the matching shard's schedule from a single
  dispatch goroutine — no per-shard goroutine fan-out.
- shell command parses -shard or -shards (mutually exclusive),
  formats progress messages with a contiguous-range label when
  applicable, and validates against ShardCount.

Integration test now uses -shards 0-15 (one subprocess invocation)
instead of a 16-iteration loop.

* fix(s3/lifecycle): allow Reader with StartTsNs=0 + Cursor=nil

The reader rejected the legitimate 'fresh subscription from epoch'
state when called from a fresh Pipeline.Run on a multi-shard worker
(no cursor file yet, all shards' MinTsNs=0). The downstream
SubscribeMetadata call handles SinceNs=0 fine; the up-front check
was over-defensive and broke the auto-scheduler completely (CI
showed 5-second-cadence retries with this exact error).

* fix(s3/lifecycle): schedule from ModTime not eventTime

A backdated or out-of-band entry update has eventTime ≈ now while
ModTime is far in the past; eventTime+Delay would push the dispatch
into the future even though the rule already fires. ModTime+Delay
is the correct fire moment. The dispatcher's identity-CAS still
catches drift between schedule and dispatch.

* fix(s3/lifecycle): -runtime cap on run-shard so it exits on quiet shards

The CI integration test sets -events 200 expecting the subprocess to
return after 200 in-shard events. But -events counts only events that
pass the shard filter; the test produces ~5 such events (bucket
create, lifecycle PUT, two object PUTs, mtime backdate), so the
reader stays in stream.Recv forever and runShellCommand hangs the
test deadline.

- weed/shell/command_s3_lifecycle_run_shard.go: add -runtime D flag.
  When > 0, Pipeline.Run runs under context.WithTimeout(D); on
  expiry the reader/dispatcher drain cleanly and the cursor saves.
- weed/s3api/s3lifecycle/dispatcher/pipeline.go: treat
  context.DeadlineExceeded the same as context.Canceled at exit
  (both are graceful shutdown signals).

* test(s3/lifecycle): pass -runtime 10s to run-shard

Pair with the new -runtime flag so the subprocess exits cleanly
after 10s instead of waiting for an event budget that never lands
on quiet shards.

* refactor(s3/lifecycle): extract HashExtended to s3lifecycle pkg

The worker's router needs the same length-prefixed sha256 of the entry's
Extended map; pulling it out of the s3api private file lets both sides
import it.

* fix(s3/lifecycle): worker captures ExtendedHash for identity-CAS

Without this, the dispatcher sends ExpectedIdentity.ExtendedHash = nil
while the live entry on the server has a non-nil hash, so every dispatch
returns NOOP_RESOLVED:STALE_IDENTITY and nothing is ever deleted.

* fix(s3/lifecycle): identity HeadFid via GetFileIdString

Meta-log events go through BeforeEntrySerialization, which clears
FileChunk.FileId and writes the Fid struct instead. Reading .FileId
directly returns "" on the worker side while the server's freshly
fetched entry still has a populated string, so the identity-CAS would
mismatch and every expiration ended in NOOP_RESOLVED:STALE_IDENTITY.

* fix(s3/lifecycle): treat gRPC Canceled/DeadlineExceeded as graceful exit

errors.Is doesn't unwrap a gRPC status error back to the stdlib ctx
errors, so a subscription that ends because runCtx was canceled was
being logged as a fatal reader error. Check status.Code as well so the
shell's -runtime cap exits cleanly.

* fix(test/s3/lifecycle): pass the gRPC port (not HTTP) to run-shard

run-shard's -s3 flag dials the LifecycleDelete gRPC service, which
listens on s3.port + 10000. The integration test was passing the HTTP
port instead, so the dispatcher's RPC just timed out and the shell
command exited under -runtime with no work done.

* chore(test/s3/lifecycle): drop emoji from Makefile output

* docs(test/s3/lifecycle): correct '-shards 0-15' wording

* fix(s3/lifecycle): reject out-of-range shard IDs in Pipeline.Run

The shell's parseShardsSpec already validates, but a programmatic caller
(scheduler, future worker config) shouldn't be able to silently produce
no-op states by passing -1 or 99.

* fix(s3/lifecycle): bound drain + final-save with their own timeouts

Shutdown was using context.Background, so a stuck dispatcher RPC or
filer save could keep Pipeline.Run from ever returning.

* fix(test/s3/lifecycle): drop self-killing pkill in stop-server

The pkill pattern \"weed mini -dir=...\" is also in the running shell's
argv (it's the recipe body), so pkill -f matches its own bash and the
recipe exits with Terminated. CI test job passed but the cleanup step
failed with exit 2. The PID file is sufficient on its own.

Chris Lu 3a192c6c57 fix(s3/lifecycle): address Phase 3 post-merge review (#9354 #9355 #9356) (#9357)
* fix(s3/lifecycle): reader handles bare /buckets parent and pre-normalizes prefix

extractBucketKey accepted /buckets/ but rejected /buckets (no trailing
slash); some delete events emit the bare form, so bucket-root events
were silently dropped. Pre-normalize BucketsPath once on Run instead
of recomputing per event.

* perf(s3/lifecycle): pool sha256 hashers in ShardID

ShardID runs on every meta-log event before the shard filter; a fresh
sha256.New per call produces measurable allocator pressure under load.
sync.Pool reuses hashers across calls.

* fix(s3/lifecycle): router skips hard deletes and missing-attribute events

A hard delete carries no schedule-relevant state — Expiration would hit
NOOP_RESOLVED at dispatch and ExpiredObjectDeleteMarker fires from a
Create on the latest version. Skip rather than burn a schedule slot.

Missing Attributes leaves ModTime at year 0001, which makes
ExpirationDays fire immediately at dispatch. Skip the event instead.

Drop the unused 'versioned' parameter from buildObjectInfo; the
dispatcher's identity-CAS handles version drift in Phase 5.

* fix(s3/lifecycle): EntryIdentity.MtimeNs holds true nanoseconds

Both computeEntryIdentity (server) and buildIdentity (router) wrote
entry.Attributes.Mtime (seconds) into a field named MtimeNs. The CAS
worked because both sides agreed, but the encoding contradicted the
field name and would break if either side later started using true
nanoseconds. Combine Mtime*1e9 + the FuseAttributes.MtimeNs nanosecond
component on both sides; the test was updated to match.

* fix(s3/lifecycle): dispatcher distinguishes ctx cancel from transport errors

A canceled or deadline-exceeded RPC is shutdown, not a transport
failure: re-queue the Match at its original DueTime with no retry-budget
burn so a quick restart can't escalate it to BLOCKED.

* fix(s3/lifecycle): reader fallback prefix normalization mirrors Run

The fallback path that builds prefix from r.BucketsPath when
bucketsPathSlash is empty (test-only entry into extractBucketKey) was
appending an unconditional '/', producing '//' if BucketsPath already
ended with one. Use the same normalization Run does.

* fix(s3/lifecycle): ObjectInfo.ModTime carries the nanosecond component

ModTime dropped FuseAttributes.MtimeNs, leaving ExpirationDays one
nanosecond off relative to EntryIdentity.MtimeNs. Pass both to
time.Unix so the precision matches the CAS witness.

Chris Lu 5ab3860005 feat(s3/lifecycle): LifecycleDelete RPC server (#9349)
* feat(s3/lifecycle): SeaweedS3LifecycleInternal.LifecycleDelete RPC

Adds the worker-to-S3 RPC the lifecycle worker calls to execute one
(rule, action) verdict against one entry. The S3 server is the only
component allowed to mutate filer state, so it gets the final word:
re-fetch, identity CAS, object-lock check, dispatch.

LifecycleDeleteRequest carries the routing tuple (bucket, object_path,
version_id, rule_hash, action_kind), the per-stream context echoed
into BlockerRecord on FATAL outcomes, and an EntryIdentity CAS witness
that lets the server detect mid-flight drift (mtime, size, head fid,
sorted-Extended hash).

LifecycleDeleteOutcome covers all five worker-actionable verdicts:
DONE / NOOP_RESOLVED / SKIPPED_OBJECT_LOCK / RETRY_LATER / BLOCKED.
Cursor-advance / pending-mutation rules per outcome are documented
inline.

Makefile updated to emit the gRPC stubs alongside the message types.

* feat(s3/lifecycle): LifecycleDelete server handler

Server-side handler for the worker-to-S3 RPC. Five-step flow:

1. Re-fetch live entry (NOT_FOUND -> NOOP_RESOLVED).
2. CAS on EntryIdentity (mtime / size / head fid / sorted-Extended
   sha256). Mismatch -> NOOP_RESOLVED with reason STALE_IDENTITY.
3. enforceObjectLockProtections with governanceBypassAllowed=false.
   Lifecycle never bypasses legal-hold or compliance retention; the
   safety scan re-attempts after the hold lifts. Lock refusal ->
   SKIPPED_OBJECT_LOCK (logged + counted, cursor advances).
4. Dispatch by action_kind:
   - EXPIRATION_DAYS / EXPIRATION_DATE: createDeleteMarker on
     versioned buckets, deleteUnversionedObjectWithClient otherwise.
   - NONCURRENT_DAYS / NEWER_NONCURRENT / EXPIRED_DELETE_MARKER:
     deleteSpecificObjectVersion (the marker is just a version).
   - ABORT_MPU: stub returning RETRY_LATER pending Phase 5 wiring.
5. Helper failures the server can't classify as transient -> BLOCKED
   with reason "FATAL_EVENT_ERROR: <detail>"; the worker writes a
   durable BlockerRecord and pauses the failing stream. Filer fetch
   transport errors -> RETRY_LATER (sustained transients eventually
   promote to BLOCKED via the worker's retry budget).

hashExtended uses length-prefixed encoding so a forged Extended
payload (e.g. one tag value containing the byte sequence of two real
tags) can't collide with a real two-tag map. Regression test pins
this.

Tests cover identity-comparison fields, hashExtended order/delimiter
stability, empty-request rejection. Full filer-integration tests come
in Layer 2.

* fix(s3/lifecycle): use stdlib bytes.Equal for ExtendedHash compare

Replaces a hand-rolled byte slice comparator with bytes.Equal —
idiomatic, slightly faster (the stdlib version is intrinsified on
amd64/arm64), and one fewer test surface to maintain.

* refactor(s3api): trim narration from lifecycle RPC + canonicalizer

Drop step-by-step doc-block narrations on LifecycleDelete and the
helpers that reproduced what the code already says. Keep WHY one-
liners at non-obvious spots: the http.Request=nil safety claim,

* refactor(s3/lifecycle): retryLater helper, drop inline literals

Adds retryLater() alongside done/noopResolved/blocked so the four
LifecycleDeleteOutcome constructions look the same. Replaces the two
inline RETRY_LATER literal returns (live-fetch transport error and
the ABORT_MPU stub) with the helper. No behavior change.

* fix(s3/lifecycle): default filer-error classification to RETRY_LATER

Versioning lookup, createDeleteMarker, deleteUnversionedObjectWithClient,
and deleteSpecificObjectVersion all do filer round-trips. Most failures
are transient (filer unavailable, slow, network blip), not deterministic
per-event errors. Returning BLOCKED for them was too aggressive: BLOCKED
halts the stream until an operator intervenes, which would surface
on every transient filer hiccup.

Default these paths to RETRY_LATER. The worker's retry budget already
promotes sustained transients to BLOCKED after a configured threshold,
which is the right place for that escalation. BLOCKED stays for the
truly deterministic error: the request-shape check (missing version_id
on noncurrent delete) and the unknown-action-kind dispatch fallback.

* fix(s3/lifecycle): honor versioning Suspended on current-version expiration

Treating Suspended-versioning buckets like never-versioned ones was
wrong: per AWS S3, current-version expiration on Suspended must
remove the existing null version and insert a new delete marker (the
same behavior a user DELETE produces). The previous code branched
only on isVersioningEnabled() — which returns false for Suspended —
and dropped through to the actual-delete path, losing the version
history that Suspended buckets are still expected to keep.

Switch to getVersioningState() and dispatch on three branches:

  Enabled    -> createDeleteMarker (current becomes non-current)
  Suspended  -> deleteSpecificObjectVersion("null"), createDeleteMarker
  Off / never configured -> deleteUnversionedObjectWithClient

The Suspended path's null-version deletion tolerates NotFound (the
null version may not exist when this is the first delete after a
versioning toggle); other errors classify as RETRY_LATER like the
rest of the dispatch.

* refactor(s3/lifecycle): trim narration on LifecycleDelete

Drop the 6-line versioning-state docblock and the inline
"transient -> RETRY_LATER" rationales; keep one-liners.

* fix(s3/lifecycle): bucket-not-found is NOOP; include ErrObjectNotFound

Three follow-ups from review (the rest were already addressed by
prior commits):

- Versioning lookup now distinguishes filer_pb.ErrNotFound
  (BUCKET_NOT_FOUND -> NOOP_RESOLVED) from genuinely transient
  failures (RETRY_LATER). A bucket deleted between live-fetch and
  versioning-lookup is benign, not transient.
- deleteUnversionedObjectWithClient and deleteSpecificObjectVersion
  now also recognise ErrObjectNotFound as a resolved-NOOP, matching
  the live-fetch step's classification.
