Chris LuandGitHub 122ca7c020 feat(s3/lifecycle): daily-replay worker behind algorithm flag (Phase 2) (#9446)
* docs(s3lifecycle): design for daily-replay worker

Captures the algorithm and dev plan iterated on in PR #9431 and the
discussion leading up to it: per-shard daily meta-log replay, walker
as a per-day pass for ExpirationDate/ExpiredDeleteMarker/NewerNoncurrent
plus a recovery branch over engine.RecoveryView(snap), explicit
retention-window input to RulesForShard, two cursor hashes
(ReplayContentHash + PromotedHash) that together detect every
invalidation case. Implementation phases are sequenced so each can
ship independently — Phase 1 (noncurrent_since stamp) just landed.

* feat(s3/lifecycle): daily-replay worker behind algorithm flag (Phase 2)

New weed/s3api/s3lifecycle/dailyrun package implementing the bounded
daily meta-log scan from the design doc. One pass per Execute per
shard: load cursor, scan events forward, route each through router.Route,
dispatch any due Match, advance the cursor on success. Halt-on-failure
keeps the cursor at the last fully-processed event so tomorrow resumes
from the same point — head-of-line blocking is the deliberate failure
signal.

Replay-only in this phase. Phase 4 wires the walker for ExpirationDate,
ExpiredDeleteMarker, NewerNoncurrent, and scan_only-promoted rules.
Until then a typed UnsupportedRuleError refuses runs on those buckets:
operators see the rejection in the activity log rather than silently
losing rules.

Behavior:
- Per-shard cursor {TsNs, RuleSetHash, PromotedHash} JSON-persisted
  under /etc/s3/lifecycle/daily-cursors/. PromotedHash always-empty in
  Phase 2; Phase 4 turns it on.
- Rule-change branch rewinds cursor to now - max_ttl when the
  replay-content hash mismatches. Cold start uses the same floor.
- Transport errors retry 3x with exponential backoff capped at 5s;
  server outcomes (RETRY_LATER / BLOCKED) halt the run without retry.
- Empty-replay sentinel: cursor TsNs=0 when no replay-eligible rules
  exist, only the hash gates a future addition.

Worker shape:
- New admin config field "algorithm" with enum streaming|daily_replay,
  default streaming. Existing deployments are unaffected.
- handler.Execute branches on the flag: streaming routes through the
  current scheduler.Scheduler, daily_replay routes through
  dailyrun.Run.
- dispatcher.NewFilerSiblingLister exported so both paths share the
  same .versions/ + null-bare lookup.

Engine integration:
- Local replayContentHash + maxEffectiveTTL helpers in dailyrun. Phase
  4's engine surface (ReplayContentHash, MaxEffectiveTTL) will replace
  them with one-line redirects; the local versions hash the same
  fields so the cursor stays valid across the swap.

Tests cover cursor persistence, unsupported-rule rejection,
hash stability under rule reordering, hash sensitivity to TTL edits,
max-TTL aggregation, dispatch retry budget, and request shape
including the identity-CAS witness.

Includes the design doc at weed/s3api/s3lifecycle/DESIGN.md so reviewers
and future phases share the same spec.

* feat(s3/lifecycle): default to daily_replay; streaming becomes the fallback knob

The streaming dispatcher hasn't shipped to users yet, so there's no
backward-compat surface to preserve. Flip the algorithm default from
streaming to daily_replay so the new path is the standard from day
one. Streaming stays as an explicit opt-in escape hatch during the
Phase 4 walker rollout; Phase 5 deletes both the flag and the
streaming code.

Buckets whose lifecycle rules require walker-bound dispatch
(ExpirationDate, ExpiredDeleteMarker, NewerNoncurrent, scan_only)
will fail the daily_replay run with the existing
UnsupportedRuleError until Phase 4 walker integration ships. Operators
hitting that case can set algorithm=streaming until the follow-up
lands.

Updates the test for the default value and renames the
unknown-value-fallback case to reflect the new default.

* fix(s3/lifecycle/dailyrun): drop per-rule done flag — it suppressed due matches

The done map was keyed by ActionKey = {Bucket, RuleHash, ActionKind}.
That's only safe when each event produces at most one match per
ActionKey with a single deterministic due-time formula —
ExpirationDays and AbortMPU fit that shape because due_time
= ev.TsNs + r.days is monotonic in event TsNs.

But NoncurrentDays paired with NewerNoncurrentVersions > 0 (allowed
in Phase 2 since it compiles to ActionKindNoncurrentDays) routes
through routePointerTransitionExpand, which emits matches for every
noncurrent sibling — each with its own SuccessorModTime taken from
the demoting event for that specific sibling. A single event can
therefore produce two matches for the same ActionKey on different
objects with wildly different DueTimes.

With the old code, a not-yet-due sibling encountered first would set
done[ActionKey] = true and then the next sibling — even though its
DueTime had already passed — would be skipped. Future events for the
same rule would also be suppressed for the rest of the run. Objects
that should have been deleted weren't.

Fix: drop the early-stop optimization. Process every match
independently. A future-DueTime match is now silently skipped without
affecting any later match. The performance hit is small (Phase 2 is a
single bounded daily pass, and the rate limiter is the real
throughput governor); the correctness gain is non-negotiable.

Also fixes the inverted comment in processMatches that described the
old check as "due_time is past now" when it actually checked
DueTime.After(now) (i.e., NOT yet due).

Adds four targeted tests:
- not-yet-due match first in slice does not suppress two later
  due matches for the same rule;
- reversed slice ordering produces identical dispatch;
- BLOCKED outcome halts the loop before later due matches are sent;
- empty match slice is a no-op.

Phase 4's walker-and-recovery integration can revisit a
per-(rule, object) memoization if profiling argues for it.

* fix(s3/lifecycle/dailyrun): address PR review — cursor advance, mode gate, ctx cancel, snapshot consistency

Addresses PR #9446 review feedback. Eight distinct fixes:

1. CURSOR ADVANCEMENT (gemini, critical). The old code advanced the
   persisted cursor to lastOK = TsNs of the last event processed,
   including events whose matches were skipped as not-yet-due. Those
   skipped matches would never be re-scanned, so objects under
   long-TTL rules would never expire.

   Track a "stuck" flag in drainShardEvents: the first event with a
   skipped (future-DueTime) match stops cursorAdvanceTo from rising,
   but the loop keeps processing later events to dispatch any that ARE
   due. The persisted cursor sits at the last fully-processed event so
   tomorrow's run re-scans from the skipped event onward and the
   future-due matches get re-evaluated when they age in.

   processMatches now returns (skippedAny, halted, err) so the drain
   loop can tell apart "event fully drained" from "event had pending
   future-due matches."

2. MODE GATE (gemini). checkSnapshotForUnsupported only checked the
   ActionKind. A replay-eligible kind with Mode != ModeEventDriven
   (e.g. ModeScanOnly via retention promotion) passed the check but
   then got silently ignored by router.Route, which gates dispatch
   on Mode == ModeEventDriven. Reject loudly with the typed error
   so admin sees the rejection in the activity log.

3. WORKERS CONFIG (gemini). The handler hardcoded 16 concurrent shard
   goroutines regardless of cfg.Workers. Add a Workers field to
   dailyrun.Config and gate the goroutine fan-out on a semaphore of
   that size; the handler now passes cfg.Workers through.

4. SINGLE SNAPSHOT PER RUN (coderabbit). Run() validated against one
   snapshot but runShard() pulled a fresh cfg.Engine.Snapshot() per
   shard. Mid-run Compile would let shards process different rule
   sets. Capture snap at the top of Run, pass it down to every shard.

5. FROZEN runNow (coderabbit). drainShardEvents and processMatches
   accepted a `now func() time.Time` and called it multiple times.
   DueTime comparisons would slip as the run wore on. Capture runNow
   once at the top of Run and thread it through as a time.Time value.

6. CTX CANCELLATION (coderabbit). The drain loop's <-ctx.Done() case
   broke out of the loop and returned nil, marking interrupted runs as
   successful. Return ctx.Err() instead so the caller propagates the
   interrupt; cursorAdvanceTo carries whatever progress was made.

7. CURSOR LOAD VALIDATION (coderabbit + gemini). The persister silently
   accepted empty files, mismatched shard_ids, and hash slices shorter
   than 32 bytes (copy() would zero-pad). Each now returns a typed
   error so the run halts and an operator investigates rather than
   silently re-scanning from time zero or persisting a zero-padded
   hash that masks corruption forever.

8. DEAD BRANCH (coderabbit). The "lastOK < startTsNs → keep persisted"
   guard in runShard was unreachable because drainShardEvents
   initialized lastOK := startTsNs and only ever raised it. Removed
   along with the new cursor-advancement semantics that handle the
   "no events processed" case implicitly.

Plus markdown lint: DESIGN.md fenced code blocks now carry a `text`
language identifier to satisfy MD040.

Skipped from the review:
- gemini's "maxTTL == 0 incorrectly skips immediate expirations":
  actions with Days <= 0 don't compile to a CompiledAction (see
  weed/s3api/s3lifecycle/action_kind.go: `if rule.X > 0`). The new
  empty-replay sentinel uses `rsh == [32]byte{}` for clarity per
  gemini's suggested form, but the behavior is equivalent.

Tests added/updated:
- TestProcessMatches_AllDueNoSkippedFlag pins skippedAny=false when
  all matches are past their DueTime.
- TestCheckSnapshotForUnsupported_NonEventDrivenModeRejected pins
  the new Mode check.
- TestFilerCursorPersister_EmptyFileReturnsError,
  _ShardIDMismatchReturnsError, _HashLengthMismatchReturnsError pin
  the new validation rules.
- Existing process-matches tests reshaped for the
  (skippedAny, halted, err) return tuple.

Full build clean. Dailyrun + worker test packages green.

Chris LuandGitHub 46bb70d93e feat(s3): stamp noncurrent_since on versioned demotions (#9431)
* feat(s3): stamp noncurrent_since on versioned demotions

A version's noncurrent TTL clock starts when the next version is
written, not at its own mtime. Today the lifecycle engine derives
that moment from the next-newer sibling's mtime — a heuristic that
drifts if the sibling is later modified and is unavailable when
the demoting event sits outside meta-log retention.

Stamp Seaweed-X-Amz-Noncurrent-Since-Ns on the demoted entry at
the two places where a PUT flips the latest pointer:
updateLatestVersionInDirectory and
updateIsLatestFlagsForSuspendedVersioning. Timestamp source is
time.Now().UnixNano() captured once per demotion — the documented
Phase 1 fallback until the filer write API surfaces its own TsNs.

Engine reads the stamp on both the bootstrap walker path and the
event-driven router; missing/zero falls back to the legacy
sibling-mtime derivation, so pre-stamp entries keep working.

Prerequisite for the daily-replay lifecycle worker (Phase 2+).

* fix(s3): address CI failure and PR review feedback

- Backdating tests must move both clocks: the lifecycle integration
  tests backdate version mtimes to simulate aging, but my earlier
  commit made the engine prefer the explicit demotion stamp over
  sibling mtime, so a real-now stamp dominated a backdated mtime and
  the rule never fired. Update backdateVersionedMtime to also rewrite
  Seaweed-X-Amz-Noncurrent-Since-Ns when the entry already carries it.
  This is a test simplification — production stamps record when the
  successor was written, not the demoted version's own mtime — but the
  resulting clock is correctly old enough.

- Refactor stamp parsing into one shared helper. Per gemini-code-assist:
  the parsing logic for ExtNoncurrentSinceNsKey was duplicated in
  router/router.go and scheduler/bootstrap.go. Move it to a new
  weed/s3api/s3lifecycle/noncurrent_since.go as exported
  SuccessorFromEntryStamp; both call sites now go through it.

- Make the parser ordering test deterministic. Per coderabbitai:
  time.Now().UnixNano() drops the monotonic clock component, so
  two back-to-back calls can decrease if the wall clock steps
  backward — the prior test was exercising OS clock behavior rather
  than the parser. Replace with fixed nanosecond values.

- Close a suspended-versioning race. Per coderabbitai: the prior
  putSuspendedVersioningObject called updateIsLatestFlagsForSuspendedVersioning
  after putToFiler returned, i.e. after the object write lock released.
  A concurrent PUT could promote a newer latest version, which we'd
  then wipe — leaving the older "null" object incorrectly current.
  Move the cleanup into the afterCreate callback so the null write and
  the .versions pointer clear (including the new demotion stamp) run
  atomically under the same lock. Best-effort logging is preserved.

* fix(s3/lifecycle): clear noncurrent_since stamp on test backdate

Backdating a version's mtime in tests is not a coherent claim about
when it became noncurrent — production stamps record the successor's
PUT time, which the test doesn't manipulate. The prior commit rewrote
the stamp to the backdated instant, but for TestLifecycleNewerNoncurrent
that creates an inconsistent state: v3's stamp says "demoted 30 days
ago" while v4's mtime (the supposed demoter) is real-now. With both
NewerNoncurrentVersions and NoncurrentDays in the same rule, the
NoncurrentDays floor passes against the backdated stamp and the
rank-based check then deletes v3 via the meta-log historical replay
that misranks against current state.

Clearing the stamp instead lets the lifecycle engine fall back to the
sibling-mtime derivation the tests were originally written against:
the legacy code path is preserved end-to-end while the new explicit-
stamp path is exercised by the unit tests in s3lifecycle/noncurrent_since_test.go
and the bootstrap-walker integration in scheduler/bootstrap_test.go.

The deeper interaction — historical meta-log replay ranking against
current state inside routePointerTransitionExpand — is pre-existing
and is no longer masked by the freshly-PUT successor's mtime once the
stamp is read. Tracked separately; not blocking this PR.

* fix(s3): stamp noncurrent_since before the .versions/ pointer flip

The pointer-flip on the .versions/ directory emits a meta-log event that
the lifecycle router consumes via routePointerTransition. The router
then calls LookupVersion on the demoted version's id. With the prior
ordering — pointer flip first, stamp second — the router could read
the demoted entry before markVersionNoncurrent landed and fall back to
the legacy sibling-mtime derivation.

Versioned COPY is the clean break: the new latest version keeps the
source object's mtime instead of recording the moment v_old was
demoted, so the fallback's successor clock can be arbitrarily wrong.
Reorder both updateLatestVersionInDirectory and
updateIsLatestFlagsForSuspendedVersioning so the stamp is written
first; the pointer flip then emits an event into a state where the
stamp is already present.

Failure of the stamp write remains non-fatal — lifecycle still falls
back to the legacy derivation in that case, with the same caveats as
before the PR but no race window.

Chris LuandGitHub 6d12ebeefe fix(mount): fall through to filer when cached dir misses a tracked inode (#9436)
lookupEntry returned ENOENT whenever the metaCache had the parent marked
cached but the child entry was absent. That's only correct when the
kernel has no record of the path either — when inodeToPath still maps
it, the three layers disagree (#9139). Triggers in practice under bursts
of concurrent metadata ops and after delete/rename events from another
mount drop the local entry without clearing the inode mapping; the test
flake fixed in b94ad8247 was the same shape on a smaller scale.

Trust the filer in that case: fall through to the existing
GetEntry path, which already loudly logs (Warningf with layer state)
when the filer also returns ErrNotFound, and otherwise serves the live
entry. Drop the Warningf from the cached-dir miss branch; it fires
thousands of times under 16-task rclone imports while the real error
path downstream covers the genuine-drift signal.

Chris LuandGitHub 514ba7a233 fix(master): route ec shard vids to NewEcVids on initial subscribe (#9435)
* fix(master): route ec shard vids to NewEcVids on initial subscribe

ToVolumeLocations appended EC shard volume IDs to NewVids, so a freshly
subscribing master client registered them in the regular-volume map via
addLocation instead of addEcLocation until the next heartbeat-driven
delta arrived. Append to NewEcVids to match the incremental path.

Fixes #9429

* fix(master): dedupe ec vids in initial subscribe snapshot

dn.GetEcShards returns per-(vid, diskId) entries, so a single EC volume
spread across multiple physical disks on one DataNode emitted the same
vid multiple times in NewEcVids. Dedupe so the snapshot carries each
vid once.

Chris LuandGitHub defe047e1a perf(volume): stream-count the gzip size when no Content-MD5 is set (#9433)
ParseUpload runs util.DecompressData on every gzipped multipart upload
just to record OriginalDataSize. The decompress materializes the full
uncompressed slice via bytes.Buffer.ReadFrom inside util.GunzipStream;
for a 64 MiB chunk that's a ~128 MiB heap spike per call (geometric
grow). On 6-way concurrent UploadPartCopy the spike dominated the
remaining heap profile after #9420/#9421/#9422/#9424/#9425.

When no Content-MD5 verification is requested the uncompressed bytes
aren't needed — only the length is. Stream the gunzip through
io.Discard and count: the pooled gzip.Reader's working set replaces
the materialized slice.

Unlike the previous attempt in #9426 the size still comes from the
real bytes, not from a client-set header.

  TotalAlloc per call, 4 MiB uncompressed body:
    materialize (was, still runs when MD5 is set):  ~16.8 MiB
    stream-count (no MD5):                             ~28 KiB

Chris LuandGitHub a64483885c fix(pb): skip Unix-socket gRPC registration on Windows (#9430) (#9434)
The same-host gRPC fast path registered /tmp/...sock paths and dialed
them with net.Listen("unix", ...) / net.Dial("unix", ...). Those paths
are POSIX-only, so on Windows the listener failed at startup and every
local gRPC call routed through the registered port lost its transport.

Gate RegisterLocalGrpcSocket to return early on Windows. ServeGrpcOnLocalSocket
and resolveLocalGrpcSocket already short-circuit when no socket is registered,
so all same-host RPCs fall back to TCP without touching any callsite.

Chris LuandGitHub ac65c6c2ca revert(volume): drop X-Seaweedfs-Original-Size hint (#9432)
Reverts #9426. The header had the volume server record OriginalDataSize
from a value set by the multipart upstream — a client-controlled
metadata field. On a volume server that isn't JWT-protected, a caller
can lie and the needle stores the lie; bounds-checking the value
doesn't change the trust shape, only the magnitude of the lie. Derive
the size from the bytes again.

The optimization only fired on multipart Content-Encoding: gzip parts
(the s3 chunk-copy fast path), a narrow case that doesn't justify the
trust dependency. A future change can attack the same heap profile by
stream-decompressing to count bytes instead of materializing the
uncompressed slice — no client-trust surface.

Chris LuandGitHub 8efa32258a feat(volume): X-Seaweedfs-Original-Size hint skips redundant gunzip (#9426)
* feat(volume): X-Seaweedfs-Original-Size hint skips redundant gunzip

The full-chunk gzip pass-through (#9425) fixed source-volume
decompression but moved the cost to the destination volume:
parseUpload still ran util.DecompressData on the forwarded gzipped
bytes, just to learn the uncompressed length so it could record
OriginalDataSize in the needle metadata. For 6-way concurrent 64 MiB
UploadPartCopy that decompress-and-discard pass dominated the
remaining heap profile after the streaming chain landed (~297 MiB
inuse via bytes.Buffer.ReadFrom inside util.GunzipStream).

Add an X-Seaweedfs-Original-Size header on the multipart part. When
the upstream sets it (the s3 chunk-copy fast path always knows the
uncompressed size — it's the source chunk's logical size) and no
Content-MD5 verification is requested (which would require
decompressed bytes to compute against), parseUpload uses the hint
directly and skips the decompress.

Header is X-* prefixed (not Seaweed-*) so it doesn't get auto-stored
as a needle pair by PairNamePrefix.

Backward compatible:
- old s3 servers don't set the header, parseUpload decompresses as
  before
- new s3 servers talking to old volumes: header is ignored, volume
  decompresses
- bad header values (non-numeric, negative, garbage) fall back to the
  existing decompress path

End-to-end repro impact (512 MiB src, 6 parallel UploadPartCopy,

Total reduction from pre-#9420 baseline: 3134 → 594 MiB (-81%).

Test exercises the four matrix corners (hint+no-MD5,
hint+part-MD5, hint+req-MD5, no-hint, garbage-hint) and bounds
allocation per case so a regression that re-introduces the
unconditional decompress fails the hint-present-no-MD5 case.

* review: bound X-Seaweedfs-Original-Size by sizeLimit and uint32

CodeQL on PR 9426 traced a new taint flow: the strconv.Atoi(hint)
value flows into pu.OriginalDataSize -> originalSize -> the existing
uint32(originalSize) cast in volume_server_handlers_write.go:73. The
cast was always there but its input was previously bounded by the
ParseUpload read path (capped at sizeLimit). Adding a user-controlled
hint bypassed that bound, so a malicious header could overflow the
uint32 silently.

Bound the hint at parse time by sizeLimit (the largest needle this
volume will accept anyway) and by math.MaxUint32 (belt-and-suspenders
in case sizeLimit is configured > 4 GiB).

Chris LuandGitHub 9a70bbfcc6 feat(s3api): full-chunk gzip pass-through skips volume-side decompress (#9427)
Building on the io.Pipe streaming chunk copy: when a copy operation
covers an entire source chunk (the common case for Harbor's
part-size = chunk-size assemble pattern), ask the source volume for
compressed bytes via Accept-Encoding: gzip and forward them to the
destination as-is.

This trades a Range fetch (where the volume decompresses the chunk
internally to satisfy the byte range) for a full-chunk fetch that
returns whatever wire bytes the chunk is stored as. For gzipped
chunks the source volume avoids the decompression entirely; we never
allocate a chunk-sized decompress buffer.

Implementation: build the source GET directly instead of going
through ReadUrlAsStream, because that helper auto-decompresses gzip
responses (which would defeat the point). Trust the response's
Content-Encoding header over caller hints — for partial ranges the
volume always returns raw bytes regardless of how the chunk is
stored, so labeling those as gzip would corrupt subsequent reads.

Chris LuandGitHub 4a04594826 feat(s3api): stream chunk copy via io.Pipe to cut peak working set (#9424)
* fix: cap pool retention so chunk-copy buffers don't hoard memory

Two pool-retention sites kept the runaway-RSS pattern in #6541 visible
even after #9420 and #9421:

* weed/util/buffer_pool: SyncPoolPutBuffer dropped a buffer back into
  sync.Pool regardless of how big it had grown. After a 64 MiB chunk
  upload through volume.PostHandler -> needle.ParseUpload, the pool
  hoarded a 64 MiB byte array per cached entry for the rest of the
  process's lifetime. Cap retention at 4 MiB; oversized buffers are
  dropped so GC can reclaim the backing array.

* weed/s3api/...copy.go: uploadChunkData left UploadOption.BytesBuffer
  unset, so operation.upload_content fell back to the package-global
  valyala/bytebufferpool. That pool also retains high-water buffers
  forever, and concurrent UploadPartCopy filled it with one chunk-sized
  buffer per concurrent upload. Provide a fresh per-call bytes.Buffer
  pre-sized to chunk + multipart framing; it's GC'd as soon as the
  upload returns.

Tests:
- weed/util/buffer_pool/sync_pool_test.go: pin the cap (oversized
  buffers don't round-trip), the inverse (right-sized buffers do), and
  nil-safety.
- weed/s3api/...copy_chunk_upload_test.go: extract newChunkUploadOption
  and pin that BytesBuffer is always non-nil and pre-sized, and that
  each call gets a distinct buffer.

chunk-sized buffers per copy in flight (download buffer + multipart-
encoded upload buffer). Under concurrent UploadPartCopy that put a
floor on RSS at concurrency × 2 × chunk_size — about 768 MiB for the
6-way / 64 MiB Harbor-style assemble repro, even after the previous
pool/retention fixes.

Replace the buffered path with an io.Pipe between the source GET and
the destination POST: ReadUrlAsStream pumps data into the pipe via a
multipart.Writer, the http.Client reads from the pipe end and POSTs
the body. In-flight per copy is now ~32 KiB (pipe hand-off + http
buffers), regardless of chunk size.

The streaming path is gated by canStreamCopyChunk: only used when no
in-transit transformation is needed (no per-chunk CipherKey, no SSE).
SSE-C / SSE-KMS / SSE-S3 paths still go through the buffered path,
which already handles re-encryption correctly.

Benchmarks (Apple M4, httptest source/dest, B/op = bytes per copy):

* review: surface shouldRetry, add int32 guard, drop redundant drains

Address review on PR 9424:

* coderabbit (HIGH, line 122): ReadUrlAsStream can set shouldRetry=true
  with readErr=nil. Before this fix, that fell through to mw.Close()
  and the destination POST succeeded against a possibly-truncated
  multipart body. Mirror downloadChunkData's explicit check and
  surface shouldRetry as a producer error so the dst POST aborts.
* gemini (line 98): chunk size is int64 but ReadUrlAsStream takes int.
  Reject sizes above MaxInt32 up front so the int(size) cast can't
  truncate negative on 32-bit platforms — same guard downloadChunkData
  uses.
* gemini (line 151): util_http.CloseResponse already drains the body
  (io.Copy(io.Discard, ...) inside the helper) before closing, so the
  manual io.Copy drains we added are redundant. Drop them.

* review: cancel source GET when destination POST fails

Address coderabbit review (line 165 / second pass on PR 9424): when
the POST leg fails or returns an error status, closing pipeReader
only fails the producer's *writes*. ReadUrlAsStream's own read loop
runs under the parent ctx, so it keeps draining the source body in
the background until EOF — wasting source-volume bandwidth and CPU
on a copy that's already failed.

Wrap streamCopyChunkRange in a child context cancelled on return.
ReadUrlAsStream checks ctx.Done() per 256 KiB tick, so the in-flight
read aborts on the next iteration once the function returns. The POST
also moves to streamCtx so the in-flight request can be cancelled the
same way if the producer fails first.

Defer-cancel runs after both legs return, so the success path still
sends EOF cleanly through pipeWriter.Close before cancellation.

Chris LuandGitHub d8bbc1d855 fix: cap pool retention so chunk-copy buffers don't hoard memory (#9422)
Two pool-retention sites kept the runaway-RSS pattern in #6541 visible
even after #9420 and #9421:

* weed/util/buffer_pool: SyncPoolPutBuffer dropped a buffer back into
  sync.Pool regardless of how big it had grown. After a 64 MiB chunk
  upload through volume.PostHandler -> needle.ParseUpload, the pool
  hoarded a 64 MiB byte array per cached entry for the rest of the
  process's lifetime. Cap retention at 4 MiB; oversized buffers are
  dropped so GC can reclaim the backing array.

* weed/s3api/...copy.go: uploadChunkData left UploadOption.BytesBuffer
  unset, so operation.upload_content fell back to the package-global
  valyala/bytebufferpool. That pool also retains high-water buffers
  forever, and concurrent UploadPartCopy filled it with one chunk-sized
  buffer per concurrent upload. Provide a fresh per-call bytes.Buffer
  pre-sized to chunk + multipart framing; it's GC'd as soon as the
  upload returns.

Tests:
- weed/util/buffer_pool/sync_pool_test.go: pin the cap (oversized
  buffers don't round-trip), the inverse (right-sized buffers do), and
  nil-safety.
- weed/s3api/...copy_chunk_upload_test.go: extract newChunkUploadOption
  and pin that BytesBuffer is always non-nil and pre-sized, and that
  each call gets a distinct buffer.

Chris LuandGitHub c917110124 fix(volume): pre-size ParseUpload buffer to request ContentLength (#9421)
* fix(volume): pre-size ParseUpload buffer to request ContentLength

The volume server's PostHandler reads the multipart upload body via
bytes.Buffer.ReadFrom inside parseUpload. The buffer comes from a
sync.Pool and may have cap=0 when the pool dropped the prior entry,
which makes ReadFrom geometric-grow on each chunk: a 64 MiB upload
allocates roughly 1+2+4+...+64 ≈ 128 MiB just to receive the body.
Under concurrent uploads (every s3 chunk-copy lands here on the
destination volume) this is one of the main contributors to the
runaway-RSS pattern in #6541 — pprof shows ~458 MiB cum in
parseUpload's bytes.Buffer.ReadFrom under Harbor-style assemble load.

Grow the buffer once up front, bounded by the existing sizeLimit so
a misreported Content-Length can't over-allocate. The receive then
fills in place.

Add a regression test that drives ParseUpload with a 16 MiB multipart
body and bounds TotalAlloc at 1.5x the chunk size (pre-fix measures
~4x, so the bound trips deterministically).

* fix(volume): guard ParseUpload pre-grow against int overflow on 32-bit

Address PR review feedback: r.ContentLength is int64, and on 32-bit
platforms int is 32 bits wide, so int(r.ContentLength) for a value above
math.MaxInt32 wraps negative and bytes.Buffer.Grow panics with
"bytes.Buffer.Grow: negative count". Skip the pre-grow optimization in
that range; the existing geometric-grow path remains correct, just
slightly more allocator pressure for that one call.

64-bit platforms (math.MaxInt == math.MaxInt64) are unaffected — the
guard only kicks in for 32-bit builds with very large sizeLimit.

* fix(volume): cap ParseUpload pre-grow at 4 MiB to bound DoS surface

Address PR review: pre-growing the receive buffer to r.ContentLength
trusts the header before any body bytes arrive. A bad header or slow /
idle client could declare a large Content-Length up to sizeLimit (256
MiB by default for volume writes) and force per-request preallocation
without sending data, turning many concurrent slow connections into
avoidable memory pressure.

Cap eager pre-grow at maxEagerPreGrow (4 MiB). Larger uploads still
benefit from the higher starting cap and fall back to ReadFrom's grow
path for the remainder. Per-request waste from a misreported
Content-Length is now bounded at 4 MiB regardless of sizeLimit.

Extract the policy as eagerPreGrow so the unit test can exercise the
gates structurally — replaces the prior TotalAlloc bound (which became
uninformative once savings were capped at 4 MiB).

Chris LuandGitHub 926a8e9351 fix(s3api): cap copy-chunk receive buffer to avoid append-grow blowup (#9420)
* fix(s3api): cap copy-chunk receive buffer to avoid append-grow blowup

downloadChunkData accumulated the streamed chunk into a nil []byte via
`chunkData = append(chunkData, data...)`. ReadUrlAsStream pumps in 256 KiB
ticks, so a 64 MiB chunk grew the slice geometrically (256K → 512K →
1M → ... → 64M), allocating ~2x the chunk size for every transferred
byte. Combined with the 4-way per-request concurrency and any number of
in-flight UploadPartCopy calls (Harbor multipart assemble), this is what
produces the runaway-RSS pattern reported in #6541.

Pre-size the receive buffer to the known sizeInt so the callback fills
in place. Add a regression test that downloads a 16 MiB chunk through
httptest and asserts TotalAlloc stays under 1.5x the chunk size — the
pre-fix code allocates ~5x and trips the bound.

Local repro (weed 4.23, 6 parallel UploadPartCopy on a 512 MiB source):

  before:  baseline 96 MiB → peak 3124 MiB, never reclaimed
  pprof:   650 MiB inuse in bytes.growSlice + 461 MiB in
           downloadChunkData.func1

* test(s3api): assert downloaded chunk content matches payload

Address PR review feedback: the allocation-bound check alone would still
pass if a future regression silently truncated or corrupted the chunk.
Compare the returned bytes against the source payload (after the
TotalAlloc measurement window so bytes.Equal doesn't pollute it).

Chris LuandGitHub ca12934834 docs(s3/lifecycle): reflect shipped reader, obsolete Phase 6 (#9419)
* test(s3/lifecycle/engine): pin delay-group dedup across buckets

Compile a 100-bucket × 5-rule snapshot where the five Days values
include duplicates (1, 1, 7, 7, 30) and assert:

- snap.actions has 500 entries — every (bucket, rule) compiles to its
  own ActionKey, no collapse.
- snap.originalDelayGroups has exactly 3 entries — the routing index
  is keyed by Delay, so same-day rules across all buckets share a
  group. This is the property that lets the dispatcher index by
  delay group rather than per-rule.
- Per-group key count = (rules with that day) × buckets, so every
  action is reachable from its group entry.

* docs(s3/lifecycle): reflect shipped reader, obsolete Phase 6

The reader didn't end up building per-filer-shard cursors,
RetainedLogRangePerShard / EarliestRetainedPositionPerShard probes,
tail_drained_streams GC, or CollectLogFileRefs heap-merge. The
filer's SubscribeMetadata already aggregates persisted + in-memory
logs across peer filers, so a single global cursor on a single
subscription is sufficient.

Mark the per-shard architecture and lost-log GC pseudocode as
implementation-note + obsoleted, rewrite Phase 6 to call out what
was descoped and why, point readers at the narrow ResumeFromDiskError
auto-degrade follow-up that is the only residual gap, and update
Layer 4 to note no multi-filer test harness is needed.

* docs(s3/lifecycle): drop stale per-shard cursor wording in Phase 3

The "one sweep per delay group" bullet still described
last_processed_original / last_processed_predicate as per-shard maps,
contradicting the implementation note added a few lines above. The
shipped reader stores one global (ts_ns, offset) position per delay
group; rewrite the bullet to match.

Chris LuandGitHub 1b1d4aa814 refactor(s3/lifecycle): extract entryUsesMetadataOnlyDelete predicate (#9417)
* test(s3/lifecycle): integration coverage for versioning + filters

First integration-test bundle building on the existing single-test
backdating harness. Each scenario follows the same shape: create
bucket, set lifecycle, PUT object, backdate mtime via filer
UpdateEntry, run the shell command for one shard sweep, assert
S3-side state.

Five new tests:

- TestLifecycleVersionedBucketCreatesDeleteMarker: Expiration on a
  versioned bucket must produce a delete marker (latest after worker
  runs is a marker) AND keep the original version directly addressable
  by versionId. ListObjectVersions confirms IsLatest=true on the
  marker.

- TestLifecycleNoncurrentVersionExpiration: NoncurrentVersionExpiration
  fires only on demoted versions. PUT v1, PUT v2 (so v1 → noncurrent),
  backdate v1, run worker. v1 must be gone, v2 still current.

- TestLifecycleExpiredDeleteMarkerCleanup: combined rule (noncurrent +
  expired-delete-marker) cleans up a sole-survivor marker. PUT v1,
  DELETE (creates marker), backdate both, run worker. Every version
  AND marker must be gone for the key.

- TestLifecycleDisabledRuleSkipsObject: rule with Status=Disabled
  must not produce dispatches even on a backdated match. Negative
  test for the engine's enabled-status gate.

- TestLifecycleTagFilter: rule with And{Prefix, Tag} only matches
  objects carrying the tag. Two backdated objects (one tagged, one
  not) — only the tagged one is removed.

Helpers extracted to keep each test focused: putVersioningEnabled,
putNoncurrentExpirationLifecycle, putExpiredDeleteMarkerLifecycle,
backdateVersionedMtime (ages a specific .versions/v_<id> entry),
runLifecycleShard (one-shot shell invocation with FATAL guard).

* test(s3/lifecycle): tighten noncurrent expiration diagnostics

Local run showed TestLifecycleNoncurrentVersionExpiration failing
with a bare 404 on HEAD(latest), not enough to tell whether v2 was
deleted, the bare-key pointer was removed, or a delete marker was
synthesized. Strengthen the test to:

- HEAD by versionId=v2 first, so we pin "v2 file still on disk"
  separately from "the latest pointer resolves to v2"
- on HEAD(latest) failure, log ListObjectVersions output (versions +
  markers, with IsLatest) so the next failure shows which side the
  bug is on rather than just NotFound

* test(s3/lifecycle): integration coverage for AbortIncompleteMultipartUpload

Exercises the lifecycleAbortMPU handler path that the prefix-based
expiration tests can't reach — routing keys off of .uploads/<id>/
directory events, not regular object events, and the dispatcher uses
a different RPC path (rm on the .uploads/<id>/ folder).

Setup: AbortIncompleteMultipartUpload rule with DaysAfterInitiation=1,
CreateMultipartUpload, UploadPart (so the directory carries the
right shape), backdate the .uploads/<uploadID>/ directory entry 30
days, run the worker. The upload must drop out of
ListMultipartUploads.

Helpers added: putAbortMPULifecycle, backdateUploadDir.

* test(s3/lifecycle): integration coverage for NewerNoncurrentVersions

NewerNoncurrentVersions=N keeps the N most recent noncurrent versions
and expires the rest. Distinct from per-version NoncurrentDays —
depends on per-version rank, not just per-version age — and routes
through routePointerTransition's "needs full expansion" path.

Setup: PUT v1, v2, v3, v4 on a versioned bucket (v4 current; v1-v3
noncurrent), backdate v1+v2+v3 so all satisfy the NoncurrentDays>=1
floor, run the worker. Expect v1+v2 expired (older noncurrent),
v3 (newest noncurrent within keep=1) and v4 (current) preserved.

Helper added: putNewerNoncurrentLifecycle.

* test(s3/lifecycle): integration coverage for suspended-versioning Expiration

Suspended versioning takes a distinct code path in lifecycleDispatch:
the VersioningSuspended branch first deletes the null version (via
deleteSpecificObjectVersion(versionId="null")) and then writes a
fresh delete marker on top. Other branches (Enabled → only writes a
marker; Off → straight rm) miss this two-step.

Setup: enable versioning, PUT v1 (real versionId), suspend
versioning, PUT again (creates the null version, demotes v1 to
noncurrent), set the Expiration rule, backdate the null at the
bare path. Expect: latest is now a fresh delete marker, the
"null" version is gone from ListObjectVersions, and v1 (noncurrent
under Enabled) still addressable directly — suspended Expiration
must only touch the null, not other versions.

Helper added: putVersioningSuspended.

* test(s3/lifecycle): integration coverage for multi-bucket sweep

A single shell-driven shard sweep must process every bucket carrying
lifecycle config, not just the first one alphabetically. Pinned
because the scheduler iterates the buckets directory and a regression
that returns early after the first match would silently disable
lifecycle for every later bucket.

Two buckets, each with their own prefix-expiration rule and a
backdated object. Both must be expired after the same sweep.

* test(s3/lifecycle): integration coverage for ObjectSizeGreaterThan filter

ObjectSizeGreaterThan is a strict > gate (filterAllows uses
ev.Size <= rule.FilterSizeGreaterThan to reject). Pinned at the
boundary: an object whose size equals the threshold must remain;
only an object strictly larger expires. Catches a > vs >= flip.

Two backdated objects on the same prefix, sizes 100 and 150 with
threshold=100 — boundary survives, larger expires.

* test(s3/lifecycle): scrub bucket lifecycle config + versions on cleanup

Tests share one weed mini server. Two pollution modes were producing
order-dependent failures:

- A later test's shard sweep would still load the prior test's
  lifecycle config (the worker reads every bucket's XML from filer
  state, and DeleteBucket alone doesn't drop lifecycle config
  cleanly on this codebase).
- Versioned-bucket tests left versions + delete markers behind that
  ListObjectsV2 can't see, so the existing best-effort empty-then-
  delete didn't actually empty those buckets.
- The AbortMPU test intentionally leaves an in-flight upload; without
  an explicit AbortMultipartUpload the bucket DELETE hits NotEmpty.

Cleanup now runs DeleteBucketLifecycle, ListObjectVersions →
DeleteObject(versionId), ListObjectsV2 → DeleteObject (catches what
ListObjectVersions missed), ListMultipartUploads → AbortMultipartUpload,
then DeleteBucket. Best-effort throughout so a half-torn-down bucket
doesn't fail the cleanup chain.

* test(s3/lifecycle): backdate both versions for NoncurrentDays clock

Per codex review: NoncurrentDays is clocked from the SUCCESSOR
version's mtime (when the displaced version became noncurrent), not
from the displaced version's own mtime. Backdating only v1 left the
clock (v2's mtime) at "now" and the rule never fired — the test was
wrong, not the production path.

Backdate v1=31d and v2=30d so v1 sits past the 1-day threshold
relative to v2, the noncurrent rule fires, and v2 stays current.

* test(s3/lifecycle): assert specific NotFound on multi-bucket deletion

Per codex review: TestLifecycleMultipleBucketsInOneSweep treated any
HeadObject error as "deleted", which lets a transport failure or
dead endpoint mask a real bug. Recognize NoSuchKey/NotFound/HTTP-404
specifically via a small isS3NotFound helper so the assertion
actually proves deletion happened, not just that the call broke.

* test(s3/lifecycle): gofmt size-filter test

* test(s3/lifecycle): integration coverage for Object Lock skip

Object Lock retention must override the lifecycle rule. The handler's
enforceObjectLockProtections check (s3api_internal_lifecycle.go:47)
returns an error when retention is active; the dispatcher then
classifies the outcome as SKIPPED_OBJECT_LOCK and the object stays.
No existing integration test reaches that outcome.

Setup: bucket created with ObjectLockEnabledForBucket=true, expiration
rule on prefix "lock/", two backdated objects under the same prefix —
one with GOVERNANCE retention until 1h from now, one without. After
the worker runs, the unlocked object expires (positive control); the
locked one survives.

Custom cleanup uses BypassGovernanceRetention so the test can drop
the locked version when the test finishes — otherwise the retention
window keeps the bucket from being deleted.

* test(s3/lifecycle): integration coverage for config update between sweeps

An operator changes the lifecycle rule between two shell-driven
sweeps. The second sweep must respect the NEW rule, not a cached
copy of the old one. Each runLifecycleShard invocation spawns a
fresh weed shell subprocess, so cached engine state from a previous
sweep doesn't persist — but a regression that caches rules across
PutBucketLifecycleConfiguration calls within the S3 server itself
would still surface here.

Sweep 1: rule prefix="first/", PUT + backdate firstKey, run worker
→ firstKey expires.

Update rule to prefix="second/", PUT + backdate secondKey AND a
new key under the OLD prefix ("first/post-update.txt"). Sweep 2
must expire only the second-prefix object; the post-update old-
prefix one must survive — config replacement, not merge.

* test(s3/lifecycle): integration coverage for ExpirationDate (past)

Rules with Expiration{Date: <past>} route through ScanAtDate in the
engine (decideMode's ActionKindExpirationDate case) — a separate
compile + dispatch branch from the EventDriven delay-group path the
Days-based tests exercise.

Past date + in-prefix object → must expire. Out-of-prefix object →
must remain. Object also backdated as defense-in-depth so the
assertion doesn't depend on whether the dispatcher consults
MinTriggerAge for date kinds.

* test(s3/lifecycle): integration coverage for bootstrap walk on existing objects

Production scenario: operator enables lifecycle on a bucket that
already holds objects from before the policy. The worker must
discover them via the bootstrap walk (BucketBootstrapper) — there
were no meta-log events to observe because the objects predate the
rule. Without the bootstrap path, only NEW writes would ever match.

Setup: PUT 5 objects (no lifecycle config yet) + 1 out-of-prefix
survivor, backdate all, THEN set the Expiration rule, run the
worker. Every in-prefix pre-existing object must be expired; the
out-of-prefix one must remain.

* test(s3/lifecycle): integration coverage for DeleteBucketLifecycle stops dispatching

Operator UX: after DeleteBucketLifecycle, the worker must observe the
removal on the next sweep and stop expiring objects under the now-gone
rule. A regression that caches old configs across
PutBucketLifecycleConfiguration → DeleteBucketLifecycle would keep
silently dropping objects.

Setup: positive control (rule active, backdated obj expires) →
DeleteBucketLifecycle → PUT + backdate a fresh object → second
sweep. The fresh object must remain.

* test(s3/lifecycle): integration coverage for empty bucket sweep no-op

A bucket carrying lifecycle config but no objects must produce a
successful sweep — no hangs, no errors, no dispatches. Pinned
because the bootstrap walker iterates bucket directories, and an
empty directory is a corner of that traversal that's easy to break
(slice-bounds bug on the first listing returning zero entries).

Asserts: worker logs "loaded lifecycle for" and "shards 0-15
complete", no FATAL output, bucket still exists after the sweep.

* test(s3/lifecycle): fix Object Lock backdate path + skip unwired ScanAtDate

ObjectLock: enabling Object Lock on a bucket implicitly enables
versioning, so PUT objects land at .versions/v_<id>, not at the bare
key. The test was calling backdateMtime (bare path) and failing in
the helper with "filer: no entry is found". Switch to
backdateVersionedMtime with the versionId returned by PutObject.

ExpirationDate: ScanAtDate dispatch path isn't wired to the run-shard
shell command yet — the bootstrap walker explicitly skips actions in
ModeScanAtDate (walker.go:141 says "SCAN_AT_DATE runs its own date-
triggered bootstrap" but no such bootstrap exists in the scheduler or
shell). Skip with a t.Skip + explanation so the test activates the
moment the date-triggered path lands.

* fix(s3/lifecycle): wire ExpirationDate dispatch through bootstrap walker

The walker explicitly skipped ModeScanAtDate actions on the comment
"SCAN_AT_DATE runs its own date-triggered bootstrap" — but no such
bootstrap exists in the scheduler or shell layer. The result: rules
with Expiration{Date: ...} compiled correctly, populated the
snapshot's dateActions map, and were never dispatched.
ExpirationDate is silently a no-op in production.

EvaluateAction already handles ActionKindExpirationDate correctly
(rejects when now.Before(rule.ExpirationDate), otherwise emits
ActionDeleteObject). The walker just needed to fall through instead
of skipping. Pre-date walks become no-ops via EvaluateAction's date
check; post-date walks expire eligible objects.

Un-skip TestLifecycleExpirationDateInThePast — it now exercises the
fixed path end-to-end.

* test(s3/lifecycle): integration coverage for multiple rules per bucket

A single bucket carries two independent Expiration rules with disjoint
prefix filters and different Days thresholds. Each rule must fire
only on its prefix; objects outside both prefixes must survive.

Pinned because Compile builds one CompiledAction per rule per kind
all sharing the same bucket index — a bug that lets one rule's
prefix or threshold leak into another (e.g. last-write-wins on a
shared map) would silently expire wrong objects.

Setup: rule A with prefix=logs/ Days=1, rule B with prefix=tmp/
Days=7. Three backdated objects: logs/access.log, tmp/scratch.bin,
data/keep.bin. After the worker runs, logs/ + tmp/ are gone;
data/ — outside both rule prefixes — survives.

* fix(s3/lifecycle): mark ScanAtDate actions active in Compile

Two layers were silently filtering ScanAtDate actions out of routing:
the walker's mode skip (fixed in e785f59d6) and Compile only marking
ModeEventDriven actions active. MatchPath / MatchOriginalWrite both
require IsActive() to emit a key, so a ScanAtDate action that's never
marked active never reaches a dispatch path even after the walker
falls through.

ScanAtDate's only dispatch path is the bootstrap walk's MatchPath
call — there's no bootstrap-completion rendezvous to wait on. Make
the active flag include ModeScanAtDate alongside the
EventDriven+BootstrapComplete combination.

ExpirationDate-based rules now actually fire end-to-end. The
TestLifecycleExpirationDateInThePast integration test exercises this.

* fix(s3/lifecycle): route date kinds via ComputeDueAt

ExpirationDate has MinTriggerAge=0, so router computed
dueTime = info.ModTime + 0 = info.ModTime. For a backdated entry
that mtime is BEFORE rule.ExpirationDate, so EvaluateAction's
now.Before(rule.ExpirationDate) check returned ActionNone and the
date rule never fired through the event-driven path.

ComputeDueAt already knows the per-kind shape — rule.ExpirationDate
for date kinds, ModTime+Days for the rest — so use it as the
single source of truth for dueTime in Route's main loop.

* test(s3/lifecycle): pin bootstrap walker date dispatch

The original TestWalk_DateActionsSkipped pinned the pre-e785f59d6
behavior that the regular walker skipped ExpirationDate. That
walker was rewired to fire date rules whose date has passed (the
SCAN_AT_DATE bootstrap was never wired); update the test to match.

Split into two: post-date entries dispatch, pre-date entries don't.

* test(s3/lifecycle): drop unused putExpiredDeleteMarkerLifecycle

The helper was never called — TestLifecycleExpiredDeleteMarkerCleanup
constructs a combined noncurrent + expired-marker rule inline, which
the helper doesn't cover. The blank-assignment workaround was just
hiding dead code; remove both.

* test(s3/lifecycle): tighten HeadObject termination check to typed not-found

Generic err != nil also passes on transport/auth/timeouts, letting
the test go green without proving the lifecycle action actually
fired. Switch the three Eventuallyf HeadObject predicates to
isS3NotFound, matching the pattern already in the multi-bucket and
expiration-date tests.

* test(s3/lifecycle): guard ListObjectVersions diagnostic against nil

When ListObjectVersions errors, listOut is nil and the diagnostic
log path panics on listOut.Versions before the real assertion fires.
Branch on (listErr != nil || listOut == nil) so the failure log is
robust whatever ListObjectVersions returned.

* refactor(s3/lifecycle): extract entryUsesMetadataOnlyDelete predicate

The metadata-only delete decision (entry.Attributes.TtlSec > 0) was
inlined in lifecycleDispatch with no direct test. Lift it into a
named predicate with the rationale comment moved onto the function
and pin the four edge cases: nil entry, nil attributes, TtlSec=0,
TtlSec>0, plus a defensive check that TtlSec<0 doesn't flip the
path on.

- TestLifecycleExpiredDeleteMarkerCleanup: combined rule (noncurrent +
  expired-delete-marker) cleans up a sole-survivor marker. PUT v1,
  DELETE (creates marker), backdate both, run worker. Every version
  AND marker must be gone for the key.

- TestLifecycleDisabledRuleSkipsObject: rule with Status=Disabled
  must not produce dispatches even on a backdated match. Negative
  test for the engine's enabled-status gate.

- TestLifecycleTagFilter: rule with And{Prefix, Tag} only matches
  objects carrying the tag. Two backdated objects (one tagged, one
  not) — only the tagged one is removed.

Helpers extracted to keep each test focused: putVersioningEnabled,
putNoncurrentExpirationLifecycle, putExpiredDeleteMarkerLifecycle,
backdateVersionedMtime (ages a specific .versions/v_<id> entry),
runLifecycleShard (one-shot shell invocation with FATAL guard).

* test(s3/lifecycle): tighten noncurrent expiration diagnostics

Local run showed TestLifecycleNoncurrentVersionExpiration failing
with a bare 404 on HEAD(latest), not enough to tell whether v2 was
deleted, the bare-key pointer was removed, or a delete marker was
synthesized. Strengthen the test to:

- HEAD by versionId=v2 first, so we pin "v2 file still on disk"
  separately from "the latest pointer resolves to v2"
- on HEAD(latest) failure, log ListObjectVersions output (versions +
  markers, with IsLatest) so the next failure shows which side the
  bug is on rather than just NotFound

* test(s3/lifecycle): integration coverage for AbortIncompleteMultipartUpload

Exercises the lifecycleAbortMPU handler path that the prefix-based
expiration tests can't reach — routing keys off of .uploads/<id>/
directory events, not regular object events, and the dispatcher uses
a different RPC path (rm on the .uploads/<id>/ folder).

Setup: AbortIncompleteMultipartUpload rule with DaysAfterInitiation=1,
CreateMultipartUpload, UploadPart (so the directory carries the
right shape), backdate the .uploads/<uploadID>/ directory entry 30
days, run the worker. The upload must drop out of
ListMultipartUploads.

Helpers added: putAbortMPULifecycle, backdateUploadDir.

* test(s3/lifecycle): integration coverage for NewerNoncurrentVersions

NewerNoncurrentVersions=N keeps the N most recent noncurrent versions
and expires the rest. Distinct from per-version NoncurrentDays —
depends on per-version rank, not just per-version age — and routes
through routePointerTransition's "needs full expansion" path.

Setup: PUT v1, v2, v3, v4 on a versioned bucket (v4 current; v1-v3
noncurrent), backdate v1+v2+v3 so all satisfy the NoncurrentDays>=1
floor, run the worker. Expect v1+v2 expired (older noncurrent),
v3 (newest noncurrent within keep=1) and v4 (current) preserved.

Helper added: putNewerNoncurrentLifecycle.

* test(s3/lifecycle): integration coverage for suspended-versioning Expiration

Suspended versioning takes a distinct code path in lifecycleDispatch:
the VersioningSuspended branch first deletes the null version (via
deleteSpecificObjectVersion(versionId="null")) and then writes a
fresh delete marker on top. Other branches (Enabled → only writes a
marker; Off → straight rm) miss this two-step.

Setup: enable versioning, PUT v1 (real versionId), suspend
versioning, PUT again (creates the null version, demotes v1 to
noncurrent), set the Expiration rule, backdate the null at the
bare path. Expect: latest is now a fresh delete marker, the
"null" version is gone from ListObjectVersions, and v1 (noncurrent
under Enabled) still addressable directly — suspended Expiration
must only touch the null, not other versions.

Helper added: putVersioningSuspended.

* test(s3/lifecycle): integration coverage for multi-bucket sweep

A single shell-driven shard sweep must process every bucket carrying
lifecycle config, not just the first one alphabetically. Pinned
because the scheduler iterates the buckets directory and a regression
that returns early after the first match would silently disable
lifecycle for every later bucket.

Two buckets, each with their own prefix-expiration rule and a
backdated object. Both must be expired after the same sweep.

* test(s3/lifecycle): integration coverage for ObjectSizeGreaterThan filter

ObjectSizeGreaterThan is a strict > gate (filterAllows uses
ev.Size <= rule.FilterSizeGreaterThan to reject). Pinned at the
boundary: an object whose size equals the threshold must remain;
only an object strictly larger expires. Catches a > vs >= flip.

Two backdated objects on the same prefix, sizes 100 and 150 with
threshold=100 — boundary survives, larger expires.

* test(s3/lifecycle): scrub bucket lifecycle config + versions on cleanup

Tests share one weed mini server. Two pollution modes were producing
order-dependent failures:

- A later test's shard sweep would still load the prior test's
  lifecycle config (the worker reads every bucket's XML from filer
  state, and DeleteBucket alone doesn't drop lifecycle config
  cleanly on this codebase).
- Versioned-bucket tests left versions + delete markers behind that
  ListObjectsV2 can't see, so the existing best-effort empty-then-
  delete didn't actually empty those buckets.
- The AbortMPU test intentionally leaves an in-flight upload; without
  an explicit AbortMultipartUpload the bucket DELETE hits NotEmpty.

Cleanup now runs DeleteBucketLifecycle, ListObjectVersions →
DeleteObject(versionId), ListObjectsV2 → DeleteObject (catches what
ListObjectVersions missed), ListMultipartUploads → AbortMultipartUpload,
then DeleteBucket. Best-effort throughout so a half-torn-down bucket
doesn't fail the cleanup chain.

* test(s3/lifecycle): backdate both versions for NoncurrentDays clock

Per codex review: NoncurrentDays is clocked from the SUCCESSOR
version's mtime (when the displaced version became noncurrent), not
from the displaced version's own mtime. Backdating only v1 left the
clock (v2's mtime) at "now" and the rule never fired — the test was
wrong, not the production path.

Backdate v1=31d and v2=30d so v1 sits past the 1-day threshold
relative to v2, the noncurrent rule fires, and v2 stays current.

* test(s3/lifecycle): assert specific NotFound on multi-bucket deletion

Per codex review: TestLifecycleMultipleBucketsInOneSweep treated any
HeadObject error as "deleted", which lets a transport failure or
dead endpoint mask a real bug. Recognize NoSuchKey/NotFound/HTTP-404
specifically via a small isS3NotFound helper so the assertion
actually proves deletion happened, not just that the call broke.

* test(s3/lifecycle): gofmt size-filter test

* test(s3/lifecycle): integration coverage for Object Lock skip

Object Lock retention must override the lifecycle rule. The handler's
enforceObjectLockProtections check (s3api_internal_lifecycle.go:47)
returns an error when retention is active; the dispatcher then
classifies the outcome as SKIPPED_OBJECT_LOCK and the object stays.
No existing integration test reaches that outcome.

Setup: bucket created with ObjectLockEnabledForBucket=true, expiration
rule on prefix "lock/", two backdated objects under the same prefix —
one with GOVERNANCE retention until 1h from now, one without. After
the worker runs, the unlocked object expires (positive control); the
locked one survives.

Custom cleanup uses BypassGovernanceRetention so the test can drop
the locked version when the test finishes — otherwise the retention
window keeps the bucket from being deleted.

* test(s3/lifecycle): integration coverage for config update between sweeps

An operator changes the lifecycle rule between two shell-driven
sweeps. The second sweep must respect the NEW rule, not a cached
copy of the old one. Each runLifecycleShard invocation spawns a
fresh weed shell subprocess, so cached engine state from a previous
sweep doesn't persist — but a regression that caches rules across
PutBucketLifecycleConfiguration calls within the S3 server itself
would still surface here.

Sweep 1: rule prefix="first/", PUT + backdate firstKey, run worker
→ firstKey expires.

Update rule to prefix="second/", PUT + backdate secondKey AND a
new key under the OLD prefix ("first/post-update.txt"). Sweep 2
must expire only the second-prefix object; the post-update old-
prefix one must survive — config replacement, not merge.

* test(s3/lifecycle): integration coverage for ExpirationDate (past)

Rules with Expiration{Date: <past>} route through ScanAtDate in the
engine (decideMode's ActionKindExpirationDate case) — a separate
compile + dispatch branch from the EventDriven delay-group path the
Days-based tests exercise.

Past date + in-prefix object → must expire. Out-of-prefix object →
must remain. Object also backdated as defense-in-depth so the
assertion doesn't depend on whether the dispatcher consults
MinTriggerAge for date kinds.

* test(s3/lifecycle): integration coverage for bootstrap walk on existing objects

Production scenario: operator enables lifecycle on a bucket that
already holds objects from before the policy. The worker must
discover them via the bootstrap walk (BucketBootstrapper) — there
were no meta-log events to observe because the objects predate the
rule. Without the bootstrap path, only NEW writes would ever match.

Setup: PUT 5 objects (no lifecycle config yet) + 1 out-of-prefix
survivor, backdate all, THEN set the Expiration rule, run the
worker. Every in-prefix pre-existing object must be expired; the
out-of-prefix one must remain.

* test(s3/lifecycle): integration coverage for DeleteBucketLifecycle stops dispatching

Operator UX: after DeleteBucketLifecycle, the worker must observe the
removal on the next sweep and stop expiring objects under the now-gone
rule. A regression that caches old configs across
PutBucketLifecycleConfiguration → DeleteBucketLifecycle would keep
silently dropping objects.

Setup: positive control (rule active, backdated obj expires) →
DeleteBucketLifecycle → PUT + backdate a fresh object → second
sweep. The fresh object must remain.

* test(s3/lifecycle): integration coverage for empty bucket sweep no-op

A bucket carrying lifecycle config but no objects must produce a
successful sweep — no hangs, no errors, no dispatches. Pinned
because the bootstrap walker iterates bucket directories, and an
empty directory is a corner of that traversal that's easy to break
(slice-bounds bug on the first listing returning zero entries).

Asserts: worker logs "loaded lifecycle for" and "shards 0-15
complete", no FATAL output, bucket still exists after the sweep.

* test(s3/lifecycle): fix Object Lock backdate path + skip unwired ScanAtDate

ObjectLock: enabling Object Lock on a bucket implicitly enables
versioning, so PUT objects land at .versions/v_<id>, not at the bare
key. The test was calling backdateMtime (bare path) and failing in
the helper with "filer: no entry is found". Switch to
backdateVersionedMtime with the versionId returned by PutObject.

ExpirationDate: ScanAtDate dispatch path isn't wired to the run-shard
shell command yet — the bootstrap walker explicitly skips actions in
ModeScanAtDate (walker.go:141 says "SCAN_AT_DATE runs its own date-
triggered bootstrap" but no such bootstrap exists in the scheduler or
shell). Skip with a t.Skip + explanation so the test activates the
moment the date-triggered path lands.

* fix(s3/lifecycle): wire ExpirationDate dispatch through bootstrap walker

The walker explicitly skipped ModeScanAtDate actions on the comment
"SCAN_AT_DATE runs its own date-triggered bootstrap" — but no such
bootstrap exists in the scheduler or shell layer. The result: rules
with Expiration{Date: ...} compiled correctly, populated the
snapshot's dateActions map, and were never dispatched.
ExpirationDate is silently a no-op in production.

EvaluateAction already handles ActionKindExpirationDate correctly
(rejects when now.Before(rule.ExpirationDate), otherwise emits
ActionDeleteObject). The walker just needed to fall through instead
of skipping. Pre-date walks become no-ops via EvaluateAction's date
check; post-date walks expire eligible objects.

Un-skip TestLifecycleExpirationDateInThePast — it now exercises the
fixed path end-to-end.

* test(s3/lifecycle): integration coverage for multiple rules per bucket

A single bucket carries two independent Expiration rules with disjoint
prefix filters and different Days thresholds. Each rule must fire
only on its prefix; objects outside both prefixes must survive.

Pinned because Compile builds one CompiledAction per rule per kind
all sharing the same bucket index — a bug that lets one rule's
prefix or threshold leak into another (e.g. last-write-wins on a
shared map) would silently expire wrong objects.

Setup: rule A with prefix=logs/ Days=1, rule B with prefix=tmp/
Days=7. Three backdated objects: logs/access.log, tmp/scratch.bin,
data/keep.bin. After the worker runs, logs/ + tmp/ are gone;
data/ — outside both rule prefixes — survives.

* fix(s3/lifecycle): mark ScanAtDate actions active in Compile

Two layers were silently filtering ScanAtDate actions out of routing:
the walker's mode skip (fixed in e785f59d6) and Compile only marking
ModeEventDriven actions active. MatchPath / MatchOriginalWrite both
require IsActive() to emit a key, so a ScanAtDate action that's never
marked active never reaches a dispatch path even after the walker
falls through.

ScanAtDate's only dispatch path is the bootstrap walk's MatchPath
call — there's no bootstrap-completion rendezvous to wait on. Make
the active flag include ModeScanAtDate alongside the
EventDriven+BootstrapComplete combination.

ExpirationDate-based rules now actually fire end-to-end. The
TestLifecycleExpirationDateInThePast integration test exercises this.

* fix(s3/lifecycle): route date kinds via ComputeDueAt

ExpirationDate has MinTriggerAge=0, so router computed
dueTime = info.ModTime + 0 = info.ModTime. For a backdated entry
that mtime is BEFORE rule.ExpirationDate, so EvaluateAction's
now.Before(rule.ExpirationDate) check returned ActionNone and the
date rule never fired through the event-driven path.

ComputeDueAt already knows the per-kind shape — rule.ExpirationDate
for date kinds, ModTime+Days for the rest — so use it as the
single source of truth for dueTime in Route's main loop.

* test(s3/lifecycle): pin bootstrap walker date dispatch

The original TestWalk_DateActionsSkipped pinned the pre-e785f59d6
behavior that the regular walker skipped ExpirationDate. That
walker was rewired to fire date rules whose date has passed (the
SCAN_AT_DATE bootstrap was never wired); update the test to match.

Split into two: post-date entries dispatch, pre-date entries don't.

* test(s3/lifecycle): drop unused putExpiredDeleteMarkerLifecycle

The helper was never called — TestLifecycleExpiredDeleteMarkerCleanup
constructs a combined noncurrent + expired-marker rule inline, which
the helper doesn't cover. The blank-assignment workaround was just
hiding dead code; remove both.

* test(s3/lifecycle): tighten HeadObject termination check to typed not-found

Generic err != nil also passes on transport/auth/timeouts, letting
the test go green without proving the lifecycle action actually
fired. Switch the three Eventuallyf HeadObject predicates to
isS3NotFound, matching the pattern already in the multi-bucket and
expiration-date tests.

* test(s3/lifecycle): guard ListObjectVersions diagnostic against nil

When ListObjectVersions errors, listOut is nil and the diagnostic
log path panics on listOut.Versions before the real assertion fires.
Branch on (listErr != nil || listOut == nil) so the failure log is
robust whatever ListObjectVersions returned.

Chris LuandGitHub 2840980c7d test(s3/lifecycle): final unit-test cleanup before integration suite (#9414)
* test(s3/lifecycle): final unit-test cleanup before integration suite

Closes the residual coverage gaps in the lifecycle packages so the
next track (Layer 3 integration tests) starts from a clean baseline.
Big coverage lifts: lifecycletest 88.7→100.0, engine 81.7→95.1,
s3lifecycle 87.8→95.0, dispatcher 60.3→67.6, router 86.1→88.8,
bootstrap 90.7→92.6. Remaining sub-100% surfaces (reader.Run,
Pipeline.Run, scheduler.Run, multi-step bootstrap orchestration)
need a live filer and belong with the integration suite.

router/helpers_test.go (formerly #9409, now stale on master because
9410-9413 absorbed adjacent surface): direct tests for the pure
helpers Route exercises indirectly — successorModTimeFromContainer
(missing/empty/non-numeric/non-positive/positive round-trip),
logicalKeyFromVersionPath (extracts logical, rejects non-.versions
parent / root-level / no-slashes / bare container), isVersionsContainerKey
(table over container forms), isVersionFolderPath (table over child
forms), isDeleteMarkerEntry (only literal "true" matches),
extractTags (nil/empty, AmzObjectTagging-prefixed only, no-tag
returns nil), hasActiveEventDrivenAction (matches only active+
event-driven, scan-only rejected, unknown skipped). Plus engine
Snapshot accessors: BucketVersioned (compiled flag, unknown bucket
false), BucketActionKeys (full list, unknown nil), Action (unknown
nil), AllActions (every kind), SnapshotID (strictly monotonic).

s3lifecycle/final_cleanup_test.go: ActionKind.String default branch
(unspecified + future-unknown render "unspecified" rather than
empty); HashExtended direct from the lifecycle package (covers it
in this package's coverage report, not just the s3api one) including
nil/empty produces no bytes and identical content hashes the same.

bootstrap/has_prefix_test.go: thin wrapper around strings.HasPrefix
exported by the package; trivial but at 0% pre-fix.

lifecycletest/eventbuilder_old_entry_test.go: pins the OldEntry
fall-through path on Delete events for WithModTime / WithTtlSec /
WithVersionID / WithExtended / WithChunks (existing tests cover
Create events that hit NewEntry only). Adds WithBootstrapVersion
across all three event shapes. Defensive: every With* option is a
no-op on a degenerate event with neither entry populated.

* test(s3/lifecycle): address coderabbit nitpicks on final cleanup

- eventbuilder empty-event test now exercises WithBootstrapVersion
  too, with an honest claim about its scope: it targets the event
  itself (not an entry), so it sets BootstrapVersion regardless of
  whether NewEntry/OldEntry are populated. Renamed the test from
  AllAreNoOpsOnEmptyEvent to NoPanicOnEmptyEvent since the original
  name overstated the contract.
- HashExtended stability check uses a 3-key map with different
  literal orders so the helper's sort path actually does work; a
  single-key check can't catch an iteration-order regression.
- HasPrefix test refactored to table-driven so adding a new edge
  case is one row instead of two assertion lines.

Chris LuandGitHub b740e22e63 test(s3/lifecycle): bundle dispatcher + engine edge-case coverage (#9413)
* test(s3/lifecycle): bundle dispatcher + engine edge-case coverage

Two-package bundle covering uncovered branches in production code that
the existing happy-path tests don't reach. Dispatcher 58.1% → 60.2%
and engine 81.0% → 81.7% (engine lift modest because most branches
were already hit; the nil-rule defensive case is otherwise unreachable
from a Compile flow).

dispatcher (4 tests):
- FilerPersister.Load with nil Store errors with a "nil Store"
  message rather than panicking at the Read call.
- FilerPersister.Save with nil Store same.
- FilerPersister.Load with a non-NotFound transport error wraps the
  shard ID into the message AND keeps the underlying error
  recoverable via errors.Is.
- FilerPersister.Load with successful empty []byte returns an empty
  map, not a JSON-decode error — pinning that an existing-but-empty
  cursor file is treated as "no entries".
- Tick initializes the retries map on first call without panic so a
  freshly-constructed Dispatcher works.
- Tick with already-canceled ctx re-queues the popped Match, returns
  zero, and never invokes the LifecycleDelete client — the Match
  must not be lost across worker restart.

engine (4 tests):
- rulePredicateSensitive(nil) returns false rather than panicking on
  the FilterTags dereference. The non-nil paths run through Compile,
  but a defensive nil-rule arrival isn't reachable that way.
- rule with no FilterTags / empty FilterTags map returns false (the
  check is len(FilterTags) > 0, so empty must classify as
  non-sensitive — pinning catches a flipped >= comparison).
- rule with a populated FilterTags returns true.

* fix(s3/lifecycle): Tick must requeue every drained Match on shutdown

Per codex review on #9413: Tick called Schedule.Drain to pop ALL due
matches at once, then iterated. If ctx canceled mid-loop, only the
current Match was re-added — everything past that index was silently
lost across the worker restart. With N due matches, up to N-1 were
dropped.

Fix: on cancellation, re-add due[i:] (current + remaining) before
returning. Matches already dispatched (due[:i]) stay processed; the
schedule is left exactly as it would be if Drain had returned only
the dispatched prefix.

Strengthen the existing test to enqueue three due matches and assert
sched.Len()==3 after a pre-canceled Tick. Pre-fix the test would have
seen Len()==1 because only the first popped Match was re-added.

Chris LuandGitHub ad77362be3 test(s3/lifecycle): bundle reader + scheduler helper coverage (#9412)
* test(s3/lifecycle): bundle reader + scheduler helper coverage

Bundles direct tests for previously-uncovered helpers in two
packages. Bumps reader 73.2% → 79.2% and scheduler 71.6% → 73.6%.

Reader Event predicates (4):
- IsCreate: NewEntry-only event classifies as create
- IsDelete: OldEntry-only event classifies as delete
- both entries (update): neither IsCreate nor IsDelete (strict
  exclusivity so router routes updates through their own path)
- no entries (degenerate): neither (so a metadata-only filer event
  with no payload doesn't trigger spurious dispatches)

Reader LogStartup (4): exercises both shape branches (single-shard
ShardID vs ShardPredicate), the explicit-StartTsNs override path, and
the Cursor.MinTsNs fallback when StartTsNs=0. Side-effect-only
function; tests pin compile-time shape and visit each code path.

Scheduler pipelineFanout.InjectEvent (5):
- nil event silently absorbed (no follow-up panic in receiving
  pipeline)
- unknown shard returns nil (forward-compat for future shard-mapping
  gaps)
- known shard succeeds
- ctx cancellation propagates when underlying pipeline's buffer fills
- routes to the correct pipeline among multiple, with cross-pipeline
  isolation proven via per-pipeline buffer state

* test(s3/lifecycle): rename canceled to canceledCtx in fanout test

Per gemini review on #9412: a bare 'canceled' identifier reads like
a bool. Rename to canceledCtx so the type is obvious at the call site.
2026-05-09 22:02:09 -07:00
Chris LuandGitHub 7996dc1d67 test(s3/lifecycle): bundle dispatcher pipeline helper coverage (#9411)
* test(s3/lifecycle): bundle dispatcher pipeline helper coverage

Five untested helpers in dispatcher/pipeline.go and one accessor in
dispatcher.go that previously sat at 0% coverage. Bumps the dispatcher
package from 58.8% → 64.7%.

observeScheduleDepth: gauge tracks Schedule.Len; pinned for empty,
populated, and post-Drain states with a unique shard label so the
test doesn't bleed into other parallel tests sharing the global
counter.

ensureEventsChan: positive EventBuffer sizes the channel; zero and
negative fall back to defaultEventBuffer so a misconfigured operator
doesn't end up with a zero-cap channel that blocks every InjectEvent;
sync.Once contract holds under 32-goroutine concurrent invocation.

InjectEvent: delivers the same pointer to p.events (no defensive
copy); a canceled ctx propagates context.Canceled rather than
silently dropping the event; allocates the channel via
ensureEventsChan so a caller can inject before Run starts.

isCtxShutdown: nil → false; context.Canceled / DeadlineExceeded →
true; gRPC-wrapped Canceled / DeadlineExceeded codes → true (so
shutdown isn't misclassified as transport failure when filer/S3
RPCs unwrap as status); other errors (Unavailable, Internal, plain)
→ false.

cursorFileName: shard 0 / 1 / 9 / 10 / 15 all pad to two digits so
on-disk filenames stay sorted by shard ID — pinned so a refactor that
drops %02d doesn't break existing cursor files.

* test(s3/lifecycle): drop ScheduleDepthGauge label series at test end

Per gemini review on #9411: even with a unique shard label, the gauge
series persists in the global Prometheus registry across test runs in
the same process. Add a defer to DeleteLabelValues so the registry
stays clean.

Chris LuandGitHub ca95d33092 test(s3/lifecycle): bundle dispatcher + engine accessor coverage (#9410)
* test(s3/lifecycle): bundle dispatcher + engine accessor coverage

Two-package bundle covering pure helpers and snapshot read-side
accessors that the router and dispatcher reach for at runtime. None
were directly tested; regressions previously surfaced only as
downstream Tick / Match / Compile failures.

dispatcher (10 tests):
- keyOf: derives every retryKey field from the Match; equal Match
  values produce equal keys (so the second dispatch hits the first's
  retry counter); distinct VersionIDs and ActionKinds produce
  distinct keys (so a noisy version can't starve a healthy one,
  and two kinds on the same object don't share a budget).
- budget(): configured value when set; defaultRetryBudget when zero
  or negative — pins the >0 guard against a flipped comparison.
- backoff(): same pattern as budget for RetryBackoff.

engine snapshot accessors (8 tests):
- OriginalDelayGroups exposes the compiled per-delay groups; rules
  with multiple kinds at different cadences land in distinct entries;
  scan-only actions don't leak into delay groups so the dispatcher
  doesn't try to drive them event-driven.
- PredicateActions populated for tag-sensitive rules, empty for non-
  tag-sensitive ones (so MatchPredicateChange doesn't route
  irrelevant kinds).
- DateActions surfaces ExpirationDate verbatim for date kinds; empty
  for non-date rules.
- MarkActive on an unknown key is a no-op (durable bootstrap-complete
  write races a recompile that drops the rule; panic here would crash
  the worker).
- MarkActive flips a fresh-no-prior-state action from inactive to
  active.
- BucketActionKeys covers every kind RuleActionKinds reports.

* test(s3/lifecycle): strengthen snapshot accessor content assertions

Per gemini review on #9410: assertions previously only checked counts
and non-empty status. Verify the specific ActionKeys land where
expected so an indexing regression that produces the right number of
items with wrong kinds gets caught.

OriginalDelayGroups: each delay group's slice asserts.Contains the
specific (bucket, rule_hash, kind) ActionKey instead of just
NotEmpty.

PredicateActions: assert.Contains the expected key instead of just
NotEmpty.

BucketActionKeys: every key.Bucket must equal the test bucket (catches
cross-bucket leak), and ElementsMatch pins kinds against
RuleActionKinds.

Chris LuandGitHub 0955d1aa08 test(s3/lifecycle): direct prefixMatches + filterAllows coverage (#9408)
Both helpers were exercised indirectly through MatchOriginalWrite /
MatchPath; pinning them directly catches a regression at the helper
level so a Match-test failure isn't the first signal of a broken
filter.

prefixMatches: empty prefix fast path; exact-prefix match; non-match
rejection; path shorter than prefix.

filterAllows: no-filter accepts any event; FilterSizeGreaterThan is
strictly > (boundary value rejected); FilterSizeLessThan is strictly
<; zero-size thresholds mean "not set" (must let any size through —
a regression treating 0 as a real threshold would reject everything);
required tag present accepts; missing key, empty tags map, wrong
value, and missing-among-multiple all reject; size + tag filters are
AND'd so either failing rejects.

Chris LuandGitHub edbe7ab140 test(s3/lifecycle): meta-log Event builder + monotonic clock fixture (#9406)
* test(s3/lifecycle): meta-log Event builder + monotonic clock fixture

Several test files build *reader.Event ad-hoc; consolidate the common
shape into the lifecycletest package as task #12 spec calls out
("fixture meta-log generator"). New tests using the builder don't
have to thread Mtime / ShardID / leaf-name semantics by hand, and
existing helpers can migrate over time without churning this PR.

NewCreate / NewDelete / NewUpdate cover the three event shapes;
WithSize / WithModTime / WithTtlSec / WithVersionID / WithExtended /
WithChunks / WithBootstrapVersion / WithShardID compose deterministic
overrides. ShardID defaults to s3lifecycle.ShardID(bucket, key) so
events route through the same shard the production reader would.

MetaLogClock issues monotonic timestamps with a configurable step
(default 1s); concurrent-safe so fan-out fixtures don't have to lock
externally.

15 unit tests pin every option, the IsCreate/IsDelete/IsUpdate
discriminators, leaf-name extraction for nested keys, ShardID
derivation, option-ordering semantics, the concurrent clock contract
under -race, and a Peek-doesn't-advance check.

* test(s3/lifecycle): address review comments on event builder

- leafOf strips trailing slashes before splitting so directory-key
  fixtures (e.g. "folder/") get the slashless leaf "folder" — pre-fix
  it returned "" which would break router tests for directory markers.
- NewUpdate now seeds OldEntry.Attributes.Mtime with the event ts
  (matching NewDelete), so a downstream router that compares mtimes
  doesn't see a synthetic 1970 epoch on the pre-update state.
- New WithOldSize / WithOldChunks / WithOldModTime options let Update
  events configure pre-update state independently. The unprefixed
  variants still target NewEntry on Update events; the With Old*
  options are no-ops on Create (no OldEntry to mutate) and never bleed
  into NewEntry.

5 new tests pin: directory-key + multi-slash leaf extraction; OldEntry
mtime default on Update; the WithOld* targeting + Create-event
no-bleed contract.

Chris LuandGitHub 9d20e71883 test(s3/lifecycle): cover worker handler lookupBucketsPath (#9407)
Three branches: gRPC error from GetFilerConfiguration must propagate
(else Execute would proceed to dial S3 with an empty buckets path
and never dispatch); a non-empty DirBuckets is honored verbatim so
operators with a non-default layout aren't force-routed to /buckets;
an empty DirBuckets falls back to the documented "/buckets" default
rather than returning empty (which would route to root). stubFilerConfigClient
embeds filer_pb.SeaweedFilerClient so methods other than the one
under test panic if called — keeps the surface narrow.

Chris LuandGitHub 1aa55f5bf9 test(s3/lifecycle): direct decideMode + RuleMode.String coverage (#9405)
Compile tests cover decideMode indirectly; these direct tests pin
every branch so a regression in the classifier itself can't slip
behind a more elaborate Compile failure.

Pinned: nil rule and Disabled status both → Disabled; ExpirationDate
→ ScanAtDate without consulting retention; metaLogRetention=0 means
unbounded so any horizon → EventDriven; horizon within retention →
EventDriven; horizon exceeding retention → ScanOnly; bootstrapLookback
adds to horizon (not retention) so a near-threshold case is still
gated; zero horizon (rule field unset) skips the gate. RuleMode.String
must render the documented names for every variant; an unknown value
collapses to "unspecified" rather than empty or panic.

Chris LuandGitHub 619cb39827 test(s3/lifecycle): pin Schedule edge cases beyond happy path (Phase 15 slice) (#9403)
* test(s3/lifecycle): pin Schedule edge cases beyond happy path

Pre-existing schedule_test covered the happy path (ordered Drain,
empty schedule, duplicates, boundary-inclusive). Five new tests pin
edge cases the dispatcher relies on:

- Drain at a time before any DueTime returns nil and leaves the heap
  intact, so the dispatcher can't accidentally consume future-due
  matches.
- NextDue after partial Drain points to the next earliest, catching
  a Drain that forgets the heap invariant.
- Add after Drain bubbles a fresh earlier DueTime to the front, so
  late-arriving high-priority matches don't sit behind older ones.
- Drain returns Matches in ascending DueTime order regardless of
  insert order — explicit pinning of the documented contract.
- Concurrent Add+Drain across 64 goroutines under -race.

* test(s3/lifecycle): actually exercise Drain in AddAfterDrain test

Per coderabbit review on #9403: the test name promised "after Drain"
but the previous body only Add'd both items without ever calling
Drain in between. Insert a real Drain (popping "drain_me") before
the second Add, so the heap-invariant-across-Drain-then-Add path is
actually pinned. Bumps the after-Drain Match's DueTime out of the
way so the Drain in step 3 returns it deterministically.

Chris LuandGitHub 435ef7f94f test(s3/lifecycle): pin toProtoActionKind + toProtoIdentity converters (#9404)
test(s3/lifecycle): pin toProtoActionKind + toProtoIdentity

The two converters are the worker-side wire to LifecycleDelete; a
miss in toProtoActionKind sends ACTION_KIND_UNSPECIFIED that the
server rejects FATAL, and a wrong toProtoIdentity flips the CAS
witness so every dispatch comes back NOOP_RESOLVED with STALE_IDENTITY
even though the entry hasn't changed.

10 tests pin: every listed s3lifecycle.ActionKind maps to its proto
counterpart (table-driven, one subtest per kind); ActionKindUnspecified
and a future unknown kind both collapse to ACTION_KIND_UNSPECIFIED
(forward compat); nil EntryIdentity stays nil (preserves the no-CAS
sentinel); a populated identity copies every field; a zero-valued
identity still produces a non-nil output so the server treats it as
a real CAS witness rather than no-CAS.

Chris LuandGitHub 1350e681c9 test(s3/lifecycle): pin Pipeline.Run dependency + shard validation (Phase 15 slice) (#9402)
* test(s3/lifecycle): pin Pipeline.Run dependency + shard validation

Pre-existing TestPipelineRunRequiresDependencies only checked that an
empty Pipeline errors; it didn't pin which specific dependency must be
present. A refactor that makes one nilable accidentally would slip
through.

8 new tests pin every validation branch in Pipeline.Run: missing
Engine / Persister / Client / FilerClient each error with "missing
required dependency"; missing BucketsPath errors with its own
distinct message so operators can spot the missing wiring; ShardID =
-1 / ShardCount errors with a range message (covers the half-open
[0, ShardCount) boundary so a < to <= refactor can't introduce a
one-past-the-end shard); and a multi-shard config with one
out-of-range entry refuses the whole run rather than silently
disabling the rest.

* test(s3/lifecycle): refactor Pipeline.Run validation tests as table-driven

Per gemini review on #9402: collapse the eight per-branch tests into
TestPipelineRunValidation with a slice of (name, mutate, wantErr)
cases. Same coverage, ~30 fewer lines, idiomatic Go pattern that
makes adding a new validation case trivial.

Chris LuandGitHub cb6e498e0b test(s3/lifecycle): pin Descriptor structural invariants (#9401)
* test(s3/lifecycle): pin Descriptor structural invariants

Pre-existing handler tests covered Capability and Detect; Descriptor
was previously untested. A drift between the form fields it advertises
and the defaults config.go reads silently breaks the admin UI in two
ways: the form renders blank (admin can't tune) or the worker clamps
to a hardcoded fallback ignoring the admin's edits. The new tests
catch both directions.

Pinned: jobType / DisplayName / Description / DescriptorVersion;
AdminConfigForm exposes a workers field whose default matches
defaultWorkers; WorkerConfigForm has a default and a field for every
cadence knob ParseConfig reads (dispatch_tick / checkpoint_tick /
refresh_interval / bootstrap_interval / max_runtime); AdminRuntime-
Defaults hits a daily cadence with bounded detection timeout and
single job per detection.

* test(s3/lifecycle): tighten Descriptor invariant assertions

Per gemini review on #9401: pin DetectionTimeoutSeconds to its exact
value (60) instead of ">0" so an accidental tweak is caught, and
assert WorkerConfigForm fields are INT64 (matching ParseConfig's
readInt64) so a STRING-type drift can't silently make the worker
ignore admin edits.

Chris LuandGitHub 6f9668c20b test(s3/lifecycle): pin lifecycleDispatch validation early-returns (#9400)
Three pure-validation paths in lifecycleDispatch return BLOCKED before
any filer call; without coverage a refactor could let them fall
through to a real delete. ABORT_MPU at dispatch time is a defensive
catch (the route bypass should never happen, but if it does the
fallthrough must not become a default-case rm). Unknown ActionKind
gets the same treatment for forward-compatibility with new proto
values. Empty version_id on noncurrent / EXPIRED_DELETE_MARKER kinds
must be rejected before deleteSpecificObjectVersion is called, so a
malformed event can't silently delete the latest pointer.

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.

foreign JobType errors with the offending name in the message; no
S3 endpoints in cluster context errors (Execute is stricter than
Detect — the admin shouldn't have routed the job there); missing
filer_grpc_address parameter errors (proposal must have been tampered
with or dropped); empty JobType is accepted as broadcast routing and
flows through to the next validation step. The dial path itself is
intentionally not covered here — those tests would need an in-process
gRPC server and belong with the integration suite.

* test(s3/lifecycle): cover InMemoryPersister deep-copy contract

8 tests pin the persister contract other lifecycle tests rely on for
cursor checkpointing: Load on an unknown shard returns an empty map
(not an error); Save then Load roundtrips; Save copies the input so
caller-side mutation doesn't bleed into stored state; Load returns a
copy so caller-side mutation of the snapshot doesn't bleed back; Save
replaces (not merges) prior state so stale resume points don't survive
restart; different shards stay isolated; saving an empty map clears
state; concurrent Save+Load is race-free under -race. A regression on
any of these silently corrupts downstream tests.

* test(s3/lifecycle): assert.NotContains for InMemoryPersister key absence

assert.Empty on a map[K]V index returns true when the value is the
zero value, which would mask a key that leaked through with int64(0).
Use assert.NotContains so the assertion fails on key presence
regardless of the stored value.

* test(s3/lifecycle): cover worker handler Detect + helpers

13 tests pin the worker-handler surface that runs without a live filer
or S3 server. Pure helpers: clusterS3Endpoints (nil context, empty
list, filter empty entries while preserving order, all-valid
passthrough); readString (missing key, nil ConfigValue, wrong kind
falls back, string returned). Capability advertises jobType with
single-job concurrency caps. Detect: nil request / nil sender / wrong
JobType all error; no S3 endpoints emits a 'skipped' activity and
completes with success; no filer addresses behaves the same; the
happy path proposes one job parameterized with the first filer
address; empty JobType is accepted (broadcast detect); a
SendProposals failure propagates without firing complete.

* test(s3/lifecycle): cover SendComplete error propagation in worker Detect

The recordingSender already supported forcing an err on SendComplete
via errOn, but no case exercised it. A SendComplete failure must
propagate so the admin learns the completion signal never landed;
proposals went out before the failure so they remain recorded.

Chris LuandGitHub 551e700e64 test(s3/lifecycle): cover scheduler configload surface (#9395)
* test(s3/lifecycle): cover scheduler configload surface

LoadCompileInputs is the bridge between the filer's bucket directory
and the engine snapshot the scheduler compiles every refresh; a missed
or misclassified bucket silently disables lifecycle for that prefix
until the next refresh. Tests pin: empty bucket dir, files at the
bucket level skipped, buckets without the lifecycle XML extended key
skipped, empty-bytes XML skipped, valid XML becomes a CompileInput,
versioning attr propagates to CompileInput.Versioned, malformed XML
surfaces as a ParseError without aborting the walk, and pagination
across the 1024 page boundary preserves bucket order.

Also covers the IsBucketVersioned (case + whitespace tolerance,
rejection of garbage values) and AllActivePriorStates (one entry per
(bucket, ruleHash, actionKind), bucket-keyed isolation) helpers.

* test(s3/lifecycle): tighten configload pagination boundary check

Switch the bucket-count check to require.Len so a regression that
returns the wrong number of buckets fails fast before the boundary
asserts panic on out-of-range index. Add explicit assertions on the
last entry of page 1 (b01023) and the first entry of page 2 (b01024)
so a pagination-loop bug that drops or duplicates the seam is caught
directly rather than only via the count check.

* test(s3/lifecycle): cover CompareVersionIds tiebreak surface

13 tests pin every documented branch of the version-id comparator and
its helpers (isNewFormatVersionId, getVersionTimestamp): equality and
short-circuit paths, null sorting last, both-new-format with smaller-
=-newer ordering, both-old-format with larger-=-newer ordering, mixed-
format compared by parsed timestamp, mixed-format with synthesized
equal timestamps, length / null / non-hex rejection, the strictly-
greater-than threshold boundary at 0x4000000000000000, and the
inverted-value invariant the comparator relies on. Getting any axis
wrong silently inverts retention rankings, which would resurrect
deleted versions or evict live ones.

* test(s3/lifecycle): use plain assert.Equal in mixed-format compare test

The previous local require := assert.New(t) shadowed testify's require
package while actually returning an assert.Assertions (continue-on-fail
semantics, not fail-fast). Use plain assert.Equal(t, ...) calls so the
behavior matches the variable's name and the rest of the file.

Chris LuandGitHub 7781eef429 test(s3/lifecycle): cover dispatcher filerSiblingLister surface (Phase 14 slice) (#9392)
* test(s3/lifecycle): cover dispatcher's filerSiblingLister surface

Tests pin the four routing-critical filer interactions on the
filerSiblingLister: Survivors (count cap, LoneEntry semantics,
null-version detection across regular files and directory-key
markers, error propagation in both list and lookup paths),
ListVersions (NotFound collapse, dir/missing-id filtering,
1024-page boundary, error propagation), LookupNullVersion (regular
file, explicit-null flag, directory-key marker accept, plain-dir
reject, NotFound collapse, error propagation), and LookupVersion
(empty version-id no-op, v_ prefix, NotFound collapse, error
propagation).

The fake SeaweedFilerClient mirrors the real filer's NotFound
shape — gRPC succeeds at stream creation and the first Recv()
surfaces filer_pb.ErrNotFound — which is what the lister's
errors.Is check depends on. NewFullPath strips a trailing slash
before splitting so directory-key markers are stored under their
slashless Name.

* test(s3/lifecycle): fake LifecycleDelete server for component tests

A reusable double for SeaweedS3LifecycleInternalServer with per-key
FIFO outcome queues, a fallback Default, and recorded request capture.
Tests of the worker pipeline that need to hit the proto boundary can
queue up DONE/NOOP/RETRY/FATAL/SKIPPED_OBJECT_LOCK responses per
(bucket, objectPath, versionId) and assert dispatch order against
Recorded(). SetError flips the server into transport-failure mode
without polluting the request log.

* test(s3/lifecycle): use struct map key for FakeLifecycleServer queues

Bucket / object path / version-id are user-supplied strings that can
contain "/" or "@", which would collide if the queue map were keyed by
"<bucket>/<object>@<version>". Switch to a struct key so the
components stay separate.

* test(s3/lifecycle): deep-copy recorded LifecycleDelete requests

Tests that mutate a Recorded() entry — or a request pointer they
already passed in — were able to corrupt the fake's bookkeeping
because the slice carried shared pointers. Clone with proto.Clone at
both record and read time so the fake holds an independent snapshot
of every arriving request and hands callers an independent snapshot
back. Tightened TestFake_VersionIDPartOfKey error checks while there.

Chris LuandGitHub 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.

Layer 2 tests pinning four reader-package contracts the dispatcher

* test(s3/lifecycle): tighten cursor composition assertions

Snapshot deep-copy: also assert cursor doesn't see keys added to the
returned map. Restore replace: freeze before second Restore and assert
IsFrozen returns false after, pinning the contract that Restore wipes
frozen state alongside the value map. Run validation: bound the call
with a 5s context timeout so a regression that lets Run reach the nil
client surfaces as a failure instead of a hang.

Chris LuandGitHub aa280443e7 test(s3/lifecycle): Layer 2 multi-shard composition for the dispatcher (#9387)
* test(s3/lifecycle): Layer 2 multi-shard composition for the dispatcher

The existing dispatcher unit tests cover individual outcomes
(DONE / RETRY_LATER / BLOCKED / etc.) on a single shard, and
pipeline_test.go has only one end-to-end happy-path assertion.
Multi-shard composition — the contract Pipeline.Run wires up at
runtime — was untested at the component level.

Add four Layer 2 tests in dispatcher/multi_shard_test.go:

  Two events for two shards land in different schedules, dispatch
  independently, and each cursor advances only for its own event
  (no cross-contamination on the action-key map).

  A poison event on shard 0 returns BLOCKED and freezes shard 0's
  cursor; shard 1's normal event continues to dispatch and its
  cursor advances. Per-shard isolation contract.

  Save/Load round-trips a per-shard cursor snapshot through the
  Persister: a fresh dispatcher restores the same TsNs map. Pins
  the contract Pipeline.Run drives on the checkpoint ticker.

  RETRY_LATER respects RetryBackoff against the wall clock — a
  Tick within the backoff window doesn't re-dispatch; a Tick past
  the new DueTime does. Guards against premature retries from
  refresh ticks landing inside the backoff.

Pipeline.Run itself can't run here (it builds a real reader.Reader),
so the tests share the same fakeClient pattern dispatcher_test.go
uses and drive Tick directly.

Chris LuandGitHub 1854101125 feat(s3/lifecycle): bootstrap re-walk cadence + operator hooks (Phase 8) (#9386)
* feat(s3/lifecycle): bootstrap re-walk cadence + operator hooks (Phase 8)

scan_only actions only fire from the bootstrap walk: the engine
classifies a rule as scan_only when its retention horizon exceeds the
meta-log retention, so event-driven routing can't be trusted. Today
each bucket walks once per process, so a long-running worker never
revisits — scan_only retention only catches up when the worker
restarts.

Replace BucketBootstrapper.known (set) with BucketBootstrapper.lastWalk
(name -> completion time). KickOffNew now re-walks a bucket whose
last walk completed more than BootstrapInterval ago. Zero interval
preserves the legacy walk-once-per-process behavior so existing
deployments don't change cadence by default. walkBucket re-stamps
on success and clears the stamp on failure (via MarkDirty), so the
next KickOffNew picks failed walks back up.

Add MarkDirty / MarkAllDirty operator hooks for forced re-walks, and
a Now func() for testable time travel.

weed shell run-shard grows --bootstrap-interval (cadence knob) and
--force-bootstrap (drop in-memory state at startup so every bucket
walks again immediately, useful when a config change should take
effect without a restart).

Tests: cadence respected (skip inside interval, re-walk past it);
zero interval keeps once-per-process; MarkDirty forces re-walk
under a 24h interval; MarkAllDirty resets every record. The
fakeClock helper guards the test clock with a mutex so race-detector
runs are clean.

* fix(s3/lifecycle): split walk state, thread BootstrapInterval through worker, drop dead flag

Three issues with the Phase 8 cadence work as it landed:

1. lastWalk did double duty as both completed-walk timestamp and
   in-flight debounce. A walk that took longer than BootstrapInterval
   would have a fresh KickOffNew start a duplicate goroutine on the
   next refresh tick because the stamp from KickOffNew looked stale
   against the interval. Split into lastCompleted (set on success)
   and inFlight (set on dispatch, cleared after the walk goroutine
   returns success or failure). KickOffNew skips inFlight buckets
   regardless of cadence.

2. The cadence knob existed on `weed shell` but not on the production
   path: scheduler.Scheduler constructed BucketBootstrapper without
   BootstrapInterval, and weed/worker/tasks/s3_lifecycle/Config had
   no field for it. Add Scheduler.BootstrapInterval, parse
   `bootstrap_interval_minutes` in ParseConfig (zero = legacy walk-
   once-per-process; negative clamps to zero), and forward it from
   the handler. Tests cover default, override, clamp, and explicit-zero.

3. --force-bootstrap was a no-op: BucketBootstrapper is freshly
   allocated at command start, so MarkAllDirty on empty state does
   nothing, and the flag couldn't influence an already-running
   process anyway. Remove it; a real runtime trigger (SIGHUP, control
   RPC) is a separate change.

In-flight regression: a blockingInjector pins the first walk in
progress while the test advances the clock past the interval. The
second KickOffNew is a no-op (inFlight check). After release, the
post-completion KickOffNew within the interval is also a no-op.

* test(s3/lifecycle): wait for lastCompleted stamp before advancing fake clock

The cadence test polled listedN to know "the walk happened" — but
that fires once both list passes are issued, while the success-stamp
lands later, after walkBucketDir returns. A clock.Advance(30m)
between those two events would record the stamp at clock+30m
instead of T0; the next assertion would then see now.Sub(last) < 1h
and skip the expected re-walk. Tight in practice but exposed under
-race / load.

Add a waitForCompleted helper that polls b.lastCompleted directly,
and use it before each clock advance in both the cadence and zero-
interval tests.

* fix(s3/lifecycle): expose bootstrap interval in worker UI; honor MarkDirty during walks

Two follow-ups on Phase 8.

The worker config descriptor had no bootstrap_interval_minutes field,
so the production operator UI couldn't enable the cadence — only the
internal ParseConfig + Scheduler wiring knew about it. Add the field
to the cadence section (MinValue=0 since 0 is the legacy default) and
include the default in DefaultValues so existing deployments see the
knob with the right preset.

MarkDirty / MarkAllDirty silently lost their effect when a walk was
in flight: the methods cleared lastCompleted, but the walk's success
path then wrote a fresh timestamp, hiding the operator's invalidation.
Track a pendingDirty set; the walk goroutine consumes the flag on
exit and skips the success stamp, so the next KickOffNew picks the
bucket up immediately.

Regression: pin a walk in progress with a blockingInjector, MarkDirty
the bucket, release the walk, and assert lastCompleted stayed empty
plus the next KickOffNew triggers a new walk inside the
BootstrapInterval window.

* refactor(s3/lifecycle): drop unused MarkDirty / MarkAllDirty + pendingDirty

These methods were the operator-hook half of Phase 8, but the only
caller (--force-bootstrap on the shell command) was removed when it
turned out to be a no-op against a freshly-allocated bootstrapper.
Nothing in production calls them anymore.

Strip the dead surface: MarkDirty, MarkAllDirty, the pendingDirty
set, the dirty-suppression branch in walkBucket, and the three tests
that only exercised those methods. BootstrapInterval-driven
re-bootstrap is the live mechanism. A real runtime trigger (SIGHUP,
control RPC) is a separate change with a real call site.

Chris LuandGitHub edfa1ce210 feat(s3/lifecycle): pointer-transition routing for live PUTs (Phase 5b/4) (#9385)
* feat(s3/lifecycle): pointer-transition routing for live PUTs (Phase 5b/4)

Bootstrap covers existing versions, but a live PUT that creates a new
.versions/<v-new> file and updates the parent's ExtLatestVersionIdKey
didn't fire NoncurrentDays / NewerNoncurrent on the displaced prior
version until the next bootstrap. Close that runtime gap.

The meta-log already emits an Update event for the .versions/
directory itself when the latest pointer changes; the router was
dropping it because buildObjectInfo returns nil for directories. New
branch in Route detects that shape (versioned bucket, NewEntry +
OldEntry both directories with the .versions/ suffix, ExtLatestVersionIdKey
changed, ID different from the new ID) and emits a Match against the
LOGICAL key with VersionID=oldID. Match.Identity comes from a single
LookupVersion RPC for the displaced version file; SuccessorModTime is
the directory update's mtime, which is the moment the displaced
version became noncurrent.

SiblingLister grows LookupVersion(bucket, key, versionID) for that
single-RPC fetch. filerSiblingLister implements it; routing path
treats NotFound as "displaced version was hard-deleted in the
meantime, suppress" rather than an error.

The router gates the lookup on at least one active event-driven
NoncurrentDays / NewerNoncurrent rule for the bucket, so most buckets
pay nothing per directory update.

Tests: pointer-flip fires NoncurrentDays with displaced version_id;
unchanged pointer skips; empty old pointer skips (first-PUT scenario);
displaced-version NotFound suppresses; no-rule skips lookup;
NewerNoncurrentVersions retains rank-0; unversioned bucket skips.

* fix(s3/lifecycle): SuccessorModTime cache + NewerNoncurrent expansion

Two correctness gaps in pointer-transition routing.

The .versions/ directory's own Attributes.Mtime is preserved across
pointer updates by updateLatestVersionInDirectory: it's a stale clock
relative to the freshly-written latest version. Using it as the
displaced version's SuccessorModTime made NoncurrentDays compute
due = staleMtime + days, which fires immediately on a fresh PUT
into an old .versions/ container. Read ExtLatestVersionMtimeKey
written by setCachedListMetadata; suppress (return no matches) when
the cache is missing rather than fall back to dir mtime.

Single-oldID lookup is only enough for pure
NoncurrentVersionExpirationDays. Any rule with NewerNoncurrentVersions
> 0 cares about the noncurrent ranks, and a pointer flip shifts every
prior noncurrent's index by one — the version that just crossed the
keep-count threshold needs to be evaluated too. When any matching
rule needs ranks, list the full .versions/ container, sort newest-
first with mtime + version-id tiebreak, and route every noncurrent
with its real index. Identity-CAS dedups against earlier schedules.

SiblingLister grows ListVersions(bucket, key); filerSiblingLister's
implementation paginates the container fully.

Two regression tests: stale dir mtime + correct cached mtime
schedules ~30 days out (not immediate); NewerNoncurrentVersions=2
with 4 versions fires on the rank-2 entry that just crossed the
threshold while rank-0/1 are retained.

* fix(s3/lifecycle): bound pointer-transition expansion to threshold crossings

routePointerTransitionExpand emitted a Match for every eligible
noncurrent on every PUT. Schedule.Add doesn't dedup, so identity-CAS
at dispatch only saved the wasted RPC, not the heap slot. A hot key
with many already-eligible versions and a count rule would push
O(versions) entries per flip, repeatedly, until dispatch caught up.

Bound the emission to versions that newly entered eligibility on
this specific flip: rank 0 (the displaced version, for the
NoncurrentDays clock) plus rank == rule.NewerNoncurrentVersions
for each active count-gated rule (the version that just crossed
from kept to expired). Bootstrap still owns full backfill for
versions that were already over-threshold.

Adds a regression with 6 versions and NewerNoncurrentVersions=2:
asserts only the rank-2 entry that just crossed fires, not the
already-over-threshold rank-3/rank-4 entries.

* fix(s3/lifecycle): suppress pointer-transition expansion when newID missing

routePointerTransitionExpand defaulted latestPos to 0 if newID wasn't
found in the listing. That made the actual newest sibling latest
against the pointer's intent, then misranked every other version. A
race between the pointer write and the version write could land us
there.

Default latestPos to -1, set it only on a real match, and suppress
the expansion when the search misses. Bootstrap repairs state on
the next walk.

The NewerNoncurrentVersions retention test was setting only
lookupEntry, so Route never reached the expansion path it claimed to
exercise. Repoint to listVersions and assert ListVersions was
consulted while LookupVersion was not. Adds a regression covering
the missing-newID suppression directly.

* fix(s3/lifecycle): include bare null version in pointer-transition routing

Bootstrap models the bare-key object as a "null" sibling alongside
.versions/ children, but the live pointer-transition path didn't.
Two cases lost:

1. oldID == "" was treated as "nothing displaced". A pre-versioning
   bare object becomes noncurrent when the first versioned PUT lands
   and the pointer flips to a real id, but live routing skipped it
   and waited for the next bootstrap.

2. The expansion path's ListVersions returned only .versions/
   children. With a bare null in the picture, the noncurrent ranks
   were wrong, so NewerNoncurrentVersions could keep the wrong
   versions and delete the right ones (or vice versa).

SiblingLister grows LookupNullVersion(bucket, key) returning the
bare entry plus an explicit-null flag (matches the bootstrap shape).
filerSiblingLister implements it via util.NewFullPath +
filer_pb.LookupEntry.

routePointerTransitionDisplaced: oldID == "" now consults
LookupNullVersion. When the bare entry exists, route it as
VersionID="null" against the LOGICAL key.

routePointerTransitionExpand: collect .versions/ children plus the
null entry into one sibling slice before sorting and ranking. The
threshold-crossing logic now sees the same N-version set that
bootstrap would compute.

Three new tests: oldID == "" with no null is a no-op (one null
lookup, no version lookup); oldID == "" with a bare null schedules
NoncurrentDays as VersionID="null"; expansion with a bare null
between .versions/ siblings places null at its mtime-correct rank
and only that rank-N entry fires.

* fix(s3/lifecycle): atomic listPageSize so test cleanup doesn't race

KickOffNew dispatches walks via `go b.walkBucket(...)`. A test that
finishes before its goroutines drain leaves them running into the
next test's t.Cleanup, which mutates listPageSize. -race spots the
read/write collision intermittently. Convert listPageSize to
atomic.Uint32; tests use Load/Store. No production semantics change.

* fix(s3/lifecycle): null becomes latest when suspended PUT clears pointer

The router treated newID == "" as if the cached
ExtLatestVersionMtimeKey were still authoritative — but that cache
holds the displaced version's mtime, written by setCachedListMetadata
when the prior version became latest. Using it as SuccessorModTime
made NoncurrentDays=30 immediately fire on a 100-day-old displaced
version even though it became noncurrent today.

When newID == "" the bare null is the new latest. Look it up,
substitute its mtime as the successor clock, and substitute "null"
as the latestPos target for the expansion path's id match. Both
displaced and expand paths now derive the right clock.

updateIsLatestFlagsForSuspendedVersioning was the upstream cause of
the staleness — it cleared ExtLatestVersionIdKey and FileNameKey but
left the cached size/mtime/etag/owner/delete-marker behind. Call
clearCachedVersionMetadata so the .versions/ container is consistent
with "null is latest". The router-side guard is still needed for
older deployments that ran the buggy code, but new writes won't
exercise the workaround.

Two regressions: 100-day-old displaced under NoncurrentDays=30 with
a today-null PUT schedules ~30d out (not immediate); same shape with
NewerNoncurrentVersions=2 ranks the null at latest and only the
rank-2 entry fires.

Chris LuandGitHub 2f7ac1d664 feat(s3/lifecycle): NoncurrentVersionExpiration via bootstrap (Phase 5b/3) (#9383)
* feat(s3/lifecycle): NoncurrentVersionExpiration via bootstrap (Phase 5b/3)

Bootstrap now expands every <key>.versions/ directory into one event
per version with sibling state pre-computed. The router fires
NoncurrentDays / NewerNoncurrent off these events using
SuccessorModTime as the noncurrent clock; previously these rules
never ran on a versioned bucket because buildObjectInfo couldn't
classify version-folder events without the latest pointer.

Mechanics

walkBucketDir treats a directory ending in .versions and carrying
ExtLatestVersionIdKey as a SeaweedFS .versions container — emit it
once and skip the recursion. Coincidentally-named directories without
the latest pointer recurse normally.

BucketBootstrapper.expandVersionsDir lists the children, sorts
newest-first by mtime, resolves the latest position from the pointer,
and injects a synthesized reader.Event per version with
BootstrapVersion populated. NoncurrentIndex is 0-based among
noncurrents in newest-first order; SuccessorModTime is the immediate
newer sibling's mtime (zero for the latest). Pointer naming a missing
or absent version falls back to the newest-by-mtime sibling so a
race window can't flag every entry as noncurrent.

routeBootstrapVersion uses BootstrapVersion to build ObjectInfo
directly (bypassing the version-folder skip in buildObjectInfo) and
runs the standard match loop. ABORT_MPU is excluded by kind-shape
gate. The schedule clock uses SuccessorModTime for noncurrents and
ModTime for the latest, so the dispatcher fires when the rule's days
threshold is met. Match.ObjectKey is the LOGICAL key,
Match.VersionID is the marker's stored version_id — the dispatcher
reaches deleteSpecificObjectVersion or createDeleteMarker correctly.

Layer 2 tests cover both sides. Router: latest fires ExpirationDays;
noncurrent fires NoncurrentDays; NewerNoncurrentVersions retains the
N newest noncurrents; ABORT_MPU never matches. Bootstrap: .versions
dir emitted once and not recursed; missing latest pointer falls back
to newest; backdated PUT (latest pointer is older by mtime) keeps
the right noncurrent index; delete-marker flag propagates.

* fix(s3/lifecycle): no VersionID for latest expirations, child-based dir disambig

Two correctness gaps in Phase 5b/3.

Bootstrap was pinning the version_id on every Match. For
EXPIRATION_DAYS / EXPIRATION_DATE on the latest version this is
unsafe: between schedule and dispatch a fresh PUT can land, the
dispatcher would still identity-match against the original version's
bytes (it still exists at that path) and the resulting delete marker
would hide the new latest. Drop VersionID for those kinds; an empty
VersionID makes the dispatcher fetch the current latest, where
identity-CAS resolves to STALE_IDENTITY and bootstrap re-schedules
with the new latest's identity. NoncurrentDays / NewerNoncurrent /
EXPIRED_DELETE_MARKER still pin the version_id since those are
version-targeted.

isVersionsDir gating on ExtLatestVersionIdKey lost a race window:
createDeleteMarker writes the version file before updating the
parent's Extended pointer, so a walk between those two steps would
see a .versions/ dir without the pointer, recurse into it, and emit
raw version files that the router drops. Match the suffix only and
let expandVersionsDir disambiguate by child inspection: if any child
carries ExtVersionIdKey it's a real .versions container and we expand;
otherwise it's a coincidentally-named user folder and we recurse via
the bucket-walk's own callback so nested entries still flow through.

Tests: latest-expiration assertion flipped to expect empty VersionID;
new tests cover the coincidentally-named-folder recursion and the
race-window expansion (children present, pointer absent).

* fix(s3/lifecycle): filter directory + missing-version-id children at listing

expandVersionsDir's listing callback collected every child with
attributes; subdirectories or entries without ExtVersionIdKey would
make it past the empty-id skip in the inner loop but still inflate
NumVersions and skew NoncurrentIndex (the rank derives from the
filtered slice's position, which was wrong when the unfiltered slice
was sorted). Drop directories at listing time and partition the
file children into a versions slice that's the actual rank source.

Test cleanups: out-of-order-mtime test now sets v1 older than v2 so
latestPos > 0 actually exercises the rank-skip branch in
expandVersionsDir; bootstrapVersionEntry preserves nanosecond
precision via MtimeNs to match markerLoneEntry's pattern; drop a
leftover unused idx variable.

* fix(s3/lifecycle): null version + canonical version-id tiebreak

Two correctness gaps in Phase 5b/3 bootstrap.

Null versions live at the bare logical path, not under .versions/.
Bootstrap previously expanded only .versions/<key>/ children, so:
  - pre-versioning objects with newer .versions/ history never had
    their null version expired by NoncurrentDays
  - suspended-bucket writes (which clear the .versions/ latest pointer
    so null becomes current) had every .versions/ child wrongly
    classified as latest by the buildObjectInfo fallback

expandVersionsDir now looks up the bare key via NewFullPath +
LookupEntry, accepts a regular file or an explicit S3 directory-key
marker (Mime set), and folds it into the sibling set with
VersionID="null". Latest resolution: pointer present + names a real
id wins; pointer absent + null exists makes null latest; otherwise
falls back to newest sibling. The walker's regular emission for the
bare entry would otherwise duplicate, so walkBucketDir now does a
two-pass walk per directory level — .versions/ first, then everything
else with a per-walk skipBare set keyed by bucket-relative path that
expandVersionsDir populates when it claims a bare null sibling.

Sort tiebreak: PUTs only set second-level Mtime, so two versions
written in the same second tied. The unstable secondary order let
old-format version filenames sort oldest-first and corrupt
NoncurrentIndex under NewerNoncurrentVersions retention. Add
CompareVersionIds to s3lifecycle/version_time.go (mirrors the
canonical comparator in s3api/s3api_version_id.go to avoid the
import cycle) and use it as a secondary key after mtime equality.

Tests: pre-versioning null-as-noncurrent, suspended null-as-current,
directory-key marker as null version, end-to-end claim through
walkBucketDir's two-pass ordering, and same-second tiebreak via
canonical version-id ordering. fakeFilerClient grows a
LookupDirectoryEntry implementation backed by the same in-memory tree.

* fix(s3/lifecycle): only treat explicit-null bare entries as current

The pointer-missing branch in expandVersionsDir made null latest as
soon as a bare object was found. That's correct for suspended-bucket
writes (s3api_object_handlers_put.go writes the bare entry with
ExtVersionIdKey="null") but wrong for the pre-versioning race window:
a brand-new version under .versions/<file> exists before the parent's
ExtLatestVersionIdKey update lands, and a pre-versioning bare object
has no version-id marker. Marking that older bare object latest hides
the real new version and skips noncurrent expiration of the null
until the next process restart/bootstrap.

Distinguish the two: lookupNullVersion now returns whether the bare
entry's Extended map carries ExtVersionIdKey="null" (the suspended
write marker). expandVersionsDir's pointer-missing branch only
promotes null to latest when explicit; otherwise it falls back to
newest-sibling, which is safe for the race window since the new
version's mtime is fresher than the bare object's.

The existing suspended-null test now uses a new helper that adds the
explicit marker. New regression test covers the race window: bare
entry without the marker + a fresh .versions/<v1> file + missing
parent pointer must keep v1 as latest and the null as noncurrent.

* fix(s3/lifecycle): only the newest item can be the explicit-null latest

The pointer-missing branch in expandVersionsDir scanned every item for
an explicit null and promoted it to latest. After a suspended->enabled
transition that's the wrong call: createVersion writes the version
file before updating ExtLatestVersionIdKey, so a bootstrap that lands
in the race window sees an older bare null with ExtVersionIdKey="null"
plus a newer .versions/<v-new> child and no parent pointer. Promoting
the null misclassifies v-new as noncurrent and skips both the new
version's current-version expiration and the null's noncurrent
scheduling until the next bootstrap.

Constrain the explicit-null branch to items[0]: if the suspended-null
write is genuinely current it'll be the newest by mtime AND tagged.
Anything else falls through to the newest-sibling default.

Adds a regression test for the suspended->re-enabled race.

* fix(s3/lifecycle): paginate bootstrap directory listings

SeaweedList(..., limit=0) is a single-page request: the filer caps
limit=0 at DirListingLimit (1000 by default) and returns whatever fits
in one round trip. expandVersionsDir and walkBucketDir both relied on
that, so any directory bigger than the cap silently truncated. For
noncurrent retention this is correctness, not just scale — a hot key
with more versions than the cap had its rank/sort math computed off
the first page only, NumVersions, NoncurrentIndex, SuccessorModTime,
and the latest-fallback all wrong, with the older versions never
scheduled until a future bootstrap.

Add a listAll helper that drives pagination via StartFromFileName +
inclusive=false, looping until a page returns fewer entries than the
configured page size. Use it in both call sites. Page size is a var
(listPageSize, default 1024) so tests can shrink it without
generating thousands of entries.

The fake filer client now mirrors the real semantics: sort children
by name, honor StartFromFileName/InclusiveStartFrom, cap at Limit.
New regression tests force a small page size and assert the full
result set is processed and the call count matches what pagination
should drive.

* perf(s3/lifecycle): stream bucket walk in two passes instead of buffering

walkBucketDir was paginating into a children slice and then iterating
twice (pass 1: .versions/, pass 2: everything else). For flat buckets
with millions of entries the buffer is a real memory spike. Drop the
materialization: each pass now drives its own listAll over the same
directory and acts on entries as they stream in. The skipBare ordering
contract is preserved — pass 2 still runs after pass 1 finishes — and
the per-pass paging keeps memory bounded by listPageSize.

Tradeoff: each directory level is listed twice. For workloads where
that matters more than the memory headroom, we can revisit; the
correctness/scale dial here is what the noncurrent rules need.

Updated three tests for the new call count: each walk now records 2
listings per directory (pass 1 + pass 2). The KickOffNew dedup tests
expect 2 calls per bucket; the pagination test expects 6 instead of 3.
