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

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

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

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

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

* feat(s3/lifecycle): LifecycleDelete server handler

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

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

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

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

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

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

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

Drop step-by-step doc-block narrations on LifecycleDelete and the
helpers that reproduced what the code already says. Keep WHY one-
liners at non-obvious spots: the http.Request=nil safety claim,
why hashExtended is length-prefixed, the safety-scan revisit
contract for SKIPPED_OBJECT_LOCK, the TODO marker for ABORT_MPU.

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

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

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

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

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

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

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

Switch to getVersioningState() and dispatch on three branches:

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

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

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

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

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

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

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

Chris LuandGitHub 4e10669221 docs(s3/lifecycle): event-driven redesign (#9346)
* docs(s3/lifecycle): event-driven redesign

Replaces the synchronous PUT-handler walk with an event-driven worker
model: meta-log reader subscribed to one filer, client-side heap merge
with per-filer-shard MessagePosition cursors, bucket-level bootstrap
with inline delete, blocked-cursor handling for fatal events, durable
retry budget for sustained-transient promotion, retention mode gate
that downgrades reader-driven rules to scan_only when log retention
falls below the rule's event-log horizon.

* docs(s3/lifecycle): record Phase 0 verified assumptions

ReadPersistedLogBuffer payload carries Extended (event marshaled via
SubscribeMetadataResponse → ToProtoEntry). Meta-log files at
topics/.system/log/<date>/<HH-MM>.<filerId> are written without TtlSec
in filer_notify_append.go; retention is unbounded by default and only
shrinks if an operator sets a filer.conf rule with a TTL on the
SystemLogDir prefix. .versions/ filenames are v_<16h-ts><16h-rand>
with old/new (inverted) format distinguished by threshold
0x4000000000000000; getVersionTimestamp / compareVersionIds give
format-agnostic ordering for successor-version discovery.

* feat(s3/lifecycle): rule evaluator and dueAt helper

Evaluate(rule, info, now) returns the EvalResult by object shape:
IsMPUInit -> AbortMultipartUpload, IsDeleteMarker -> ExpireDeleteMarker
when sole survivor, IsLatest -> DeleteObject (Days or Date), non-current
-> DeleteVersion (Days fallback to ModTime when SuccessorModTime is
zero; NewerNoncurrent retention enforced when both are set).

ComputeDueAt mirrors Evaluate's shape and returns the earliest eligible
wall-clock time for the same (rule, info), used by the reader/bootstrap
to decide pending vs inline-delete.

Adds StatusEnabled/Disabled and SmallDelay consts and an IsMPUInit
flag on ObjectInfo so .uploads/<id>/ entries route to AbortMPU without
overloading IsLatest.

No callers; package compiles standalone.

* feat(s3/lifecycle): MinTriggerAge for safety-scan cadence

Returns the smallest non-zero day threshold across the rule's actions.
Used as max(MinTriggerAge, kindFloor) for the per-kind cadence; date,
count-only, and delete-marker-only rules return 0 so callers fall
through to their kind-specific floor.

* feat(s3/lifecycle): EventLogHorizon for retention mode gate

Returns the maximum event age the reader needs for a rule. Days-based
kinds return their day threshold; pure NewerNoncurrent (count) and
ExpiredObjectDeleteMarker return SmallDelay. Date rules return 0 (the
gate skips them). Multi-action rules take the max — strictest horizon
wins.

Drives the Phase 2 mode gate: metaLogRetention < EventLogHorizon(rule)
+ bootstrapLookbackMin -> scan_only with RETENTION_BELOW_HORIZON.

* feat(s3/lifecycle): RuleHash for per-rule state CAS

sha256 over canonicalized form, first 8 bytes. Stable across tag-key
reorder, prefix trailing-slash variation, ID renames, and Status flips
(state continuity is preserved when an operator toggles
Enabled/Disabled). Different action shapes — different days, filter,
or action type — hash differently.

Used by the per-rule state directory layout
/etc/s3/lifecycle/<bucket>/<rule_hash_hex>/ and by the bootstrap
detector's reconcile-on-PUT.

* feat(s3/lifecycle): add s3_lifecycle.proto storage schema

Defines the durable types backing the lifecycle worker:
LifecycleState (per-rule mode + bootstrap_complete + degraded_reason
incl. RETENTION_BELOW_HORIZON / LOST_LOG), PendingItem, EntryIdentity,
BootstrapState, ReaderState (per-filer-shard cursors plus
tail_drained_streams marker), BlockerRecord (rule_hash optional for
pre-evaluation failures), RetryBudgetEntry with the four-shape
StreamKey oneof, and RetryTarget (no action / no expected_identity —
retry replays handler against current state).

No callers; schema only. Wired into the pb Makefile.

* feat(s3/lifecycle): add S3LifecycleParams to TaskParams

Wires lifecycle subroutines into the existing worker dispatch.
Subtype is READ (cluster-singleton meta-log reader), BOOTSTRAP
(per-bucket walker), or DRAIN (per-rule pending). bucket / rule_hash
populated for the latter two; ContinuationHint is an advisory resume
point for kill-resumable BOOTSTRAP / READ.

oneof tag = 14, after the existing ec_balance_params at 13.

* fix(s3/lifecycle): noncurrent delete markers honor NoncurrentDays

A non-current delete marker is just another version per AWS S3 spec
and is eligible under NoncurrentVersionExpirationDays. The
IsDeleteMarker special case is meant only for the *current* delete
marker (sole-survivor ExpiredObjectDeleteMarker action), so guard
that switch arm with IsLatest. Without IsLatest, the bootstrap walker
silently skipped pre-existing non-current delete markers under a
NoncurrentDays rule because ComputeDueAt returned zero.

Mirrors the same fix in evaluate.go so the runtime decision matches.

* fix(s3/lifecycle): preserve prefix trailing slash in RuleHash

"logs" and "logs/" match different object sets under literal
strings.HasPrefix semantics: "logs" matches "logsmore/x", "logs/" does
not. Collapsing them in the hash would let an XML edit silently bind
the new rule to the previous rule's durable state directory, causing
stale bootstrap_complete and stale pending entries against a rule
that now matches a different set.

* fix(s3/lifecycle): add UNSPECIFIED sentinels to enum zero values

Proto3 best practice: enum 0 should be an _UNSPECIFIED sentinel, not
an active value. Persisted state schemas care most: a partially
populated payload (or one written by an older binary that didn't set
the field) would otherwise silently default to a semantically active
value.

- LifecycleState.RuleKind: shifts EXPIRATION_DAYS..EXPIRED_DELETE_MARKER
  from 0..5 to 1..6, with RULE_KIND_UNSPECIFIED at 0.
- LifecycleState.RuleMode: shifts EVENT_DRIVEN..PENDING_BOOTSTRAP from
  0..4 to 1..5.
- LifecycleState.DegradedReason: replaces NONE=0 with
  DEGRADED_REASON_UNSPECIFIED=0 (operators treat both as healthy).
- StreamKind: shifts ORIGINAL..PENDING from 0..3 to 1..4.
- S3LifecycleParams.Subtype: shifts READ..DRAIN from 0..2 to 1..3, so
  an unset subtype no longer routes into the cluster-singleton READ task.

No on-disk state has been written yet; renumbering is safe.

* docs(s3/lifecycle): per-action state, not per-rule

A single AWS lifecycle XML <Rule> can declare multiple actions in
parallel (e.g. ExpirationDays=90 + AbortMPU=7 + NoncurrentDays=30).
Each must drive its own delay/horizon/mode/pending stream
independently. Modeling the rule as one compiled entry with one kind
collapses these — picking the smallest delay (7d MPU) means the 90d
expiration cursor advances past objects that aren't yet due, and the
90d action never re-fires.

Restructure storage to per-action: every XML rule expands into N
compiled actions; state lives at <bucket>/<rule_hash>/<action_kind>/.
The intermediate rule_hash directory keeps a rule's actions grouped
for operator listing. Each action has its own state file with its own
mode + bootstrap_complete + degraded_reason; sibling actions of the
same rule can degrade independently.

* fix(s3/lifecycle): per-action proto schema + safety-scan counters

Realigns the durable schema with the per-action storage model and the
safety-scan contract in the design doc.

- Promote LifecycleState.RuleKind to a top-level ActionKind enum and
  rename rule_kind -> action_kind. The same enum now also keys
  BootstrapKey, PendingKey, and BlockerRecord so per-action streams
  under one rule never collapse.
- LifecycleState now keyed by (rule_hash, action_kind). Added
  last_safety_scan_ts_ns / next_safety_scan_ts_ns and the four
  observability counters the design specifies (evaluated_total,
  expired_total, metadata_only_total, error_total). Dropped
  last_evaluated_ns, deleted_total, skipped_object_lock_total, and
  pending_size — subsumed or out-of-band.
- BlockerRecord.action_kind is OPTIONAL (UNSPECIFIED for
  pre-evaluation failures, just like rule_hash).

No on-disk state has been written yet; the renumbering / rename is
free.

* fix(s3/lifecycle): per-action MinTriggerAge / EventLogHorizon helpers

The retention mode gate and safety-scan cadence run on each compiled
action independently. Taking a "min/max across all actions in the
rule" — as the previous helpers did — was wrong: a 90d ExpirationDays
sibling alongside a 7d AbortMPU action would cause the 90d cursor to
advance at 7d (because MinTriggerAge picked the smallest), and the
ExpirationDays action would never re-fire on objects that aged past
the 7d sweep window before reaching 90d.

Both helpers now take an ActionKind and return the threshold for that
specific action only. Returns 0 if the rule does not declare the
requested kind, which makes the gate a no-op and the cadence fall
through to the kind floor.

Also adds RuleActionKinds(rule), the canonical expansion that the
engine uses at compile time to turn one XML rule into N compiled
actions. NewerNoncurrentVersions paired with NoncurrentDays is
subsumed into a single NONCURRENT_DAYS action (AWS-paired
conditions); only when NewerNoncurrent stands alone does it become
NEWER_NONCURRENT.

* fix(s3/lifecycle): length-prefix RuleHash to remove delimiter ambiguity

The previous encoding used "tag=K=V\n" lines, which is ambiguous: a
tag (a=b, c) serializes identically to (a, b=c). A prefix containing
"\nexp_days=99" could likewise forge an action field. Either could
silently bind two semantically different rules to the same per-rule
state directory.

Switch to a length-prefixed canonical form: each scalar is written as
<field-tag-byte> <uvarint-length> <bytes>. Field-tag bytes namespace
each scalar so ("a=b" tag-key) and ("a" tag-key with "=b" leakage)
can't collide. Three regression tests pin the resistance.

* docs(s3/lifecycle): ActionKey is the engine identity, not rule_hash

Finishes the per-action restructure across the engine pseudocode,
bootstrap completion, drain locks, detector paths, policy CAS, and
Phase 2 plan. Every per-action data structure — engine indexes,
target modes, newly-completed sets, bootstrap completion bits, drain
keys, locks, metrics, status — is now keyed by
ActionKey{rule_hash, action_kind}, not by rule_hash alone.

Without this, sibling actions under one XML rule still shared
scheduling state in the engine: originalDelayGroups holding
[]ruleHash means a rule's 7d AbortMPU and 90d ExpirationDays
collapse into one entry, the smaller delay wins for cursor advance,
and the larger sibling never re-fires.

Helper API tightened: EvaluateAction(rule, kind, info, now) and
ComputeDueAt(rule, kind, info) replace the aggregate-rule signatures
so a caller asks one specific action's eligibility against one
entry, never "any action of this rule." Drain task lock includes
action_kind so siblings have independent re-arm timers. Policy CAS
moves from rule_hash to ActionKey membership.

* fix(s3/lifecycle): kind-aware EvaluateAction / ComputeDueAt

Replaces the aggregate-rule signatures with per-action ones:
EvaluateAction(rule, kind, info, now) and ComputeDueAt(rule, kind,
info). The old Evaluate(rule, info, now) could return the verdict of
ANY action declared on the rule, which sat wrong with the per-action
engine indexing (each ActionKey has its own delay group, mode, and
pending stream).

Each helper now decides exactly one (rule, kind) compiled action's
fate against one entry. Asking for a kind the rule doesn't declare,
or asking against the wrong object shape for that kind, returns
ActionNone / zero — never silently routes to a sibling.

Multi-action regression test: a rule with ExpirationDays=90 and
AbortMPU=7 evaluates each kind independently for the same entry; the
7d window has no influence on the 90d eligibility decision.

Chris LuandGitHub d7d834b8f9 peer chunk sharing 1/8: proto definitions (#9130)
proto: define MountRegister/MountList and MountPeer service

Adds the wire types for peer chunk sharing between weed mount clients:

* filer.proto: MountRegister / MountList RPCs so each mount can heartbeat
  its peer-serve address into a filer-hosted registry, and refresh the
  list of peers. Tiny payload; the filer stores only O(fleet_size) state.

* mount_peer.proto (new): ChunkAnnounce / ChunkLookup RPCs for the
  mount-to-mount chunk directory. Each fid's directory entry lives on
  an HRW-assigned mount; announces and lookups route to that mount.

No behavior yet — later PRs wire the RPCs into the filer and mount.
See design-weed-mount-peer-chunk-sharing.md for the full design.

* Match Go TTL Display: return empty string when unit is Empty

Go checks `t.Unit == Empty` separately and returns "" for TTLs
with nonzero count but Empty unit. Rust only checked is_empty()
(count==0 && unit==0), so count>0 with unit=0 would format as
"5 " instead of "".

* Match Go error behavior for truncated needle data in read_body_v2

Go's readNeedleDataVersion2 returns "index out of range %d" errors
(indices 1-7) when needle body or metadata fields are truncated.
Rust was silently tolerating truncation and returning Ok. Now returns
NeedleError::IndexOutOfRange with the matching index for each field.

* Match Go download throttle: return JSON error instead of plain text

* Match Go crop params: default x1/y1 to 0 when not provided

* Match Go ParsePath: support _delta suffix on file IDs for sub-file addressing

* Match Go chunk manifest: add Accept-Ranges, Content-Disposition, filename fallback, MIME detection

* Match Go privateStoreHandler: use proper JSON error for unsupported methods

* Match Go Destroy: add only_empty parameter to reject non-empty volume deletion

* Fix compilation: set_read_only_persist and set_writable return ()

These methods fire-and-forget save_vif internally, so gRPC callers
should not try to chain .map_err() on the unit return type.

* Match Go SaveVolumeInfo: check writability and propagate errors in save_vif

* Match Go VolumeDelete: propagate only_empty to delete_volume for defense in depth

The gRPC VolumeDelete handler had a pre-check for only_empty but then
passed false to store.delete_volume(), bypassing the store-level check.
Go passes req.OnlyEmpty directly to DeleteVolume. Now Rust does the same
for defense in depth against TOCTOU races (though the store write lock
makes this unlikely).

* Match Go ProcessRangeRequest: return full content for empty/oversized ranges

Go returns nil from ProcessRangeRequest when ranges are empty or total
range size exceeds content length, causing the caller to serve the full
content as a normal 200 response. Rust was returning an empty 200 body.

* Match Go Query: quote JSON keys in output records

Go's ToJson produces valid JSON with quoted keys like {"name":"Alice"}.
Rust was producing invalid JSON with unquoted keys like {name:"Alice"}.

* Match Go VolumeCopy: reject when no suitable disk location exists

Go returns ErrVolumeNoSpaceLeft when no location matches the disk type
and has sufficient space. Rust had an unsafe fallback that silently
picked the first location regardless of type or available space.

* Match Go DeleteVolumeNeedle: check noWriteOrDelete before allowing delete

Go checks v.noWriteOrDelete before proceeding with needle deletion,
returning "volume is read only" if true. Rust was skipping this check.

* Match Go ReceiveFile: prefer HardDrive location for EC and use response-level write errors

Two fixes: (1) Go prefers HardDriveType disk location for EC volumes,
falling back to first location. Returns "no storage location available"
when no locations exist. (2) Write failures are now response-level
errors (in response body) instead of gRPC status errors, matching Go.

* Match Go CopyFile: sync EC volume journal to disk before copying

Go calls ecVolume.Sync() before copying EC volume files to ensure the
.ecj journal is flushed to disk. Added sync_to_disk() to EcVolume and
call it in the CopyFile EC branch.

* Match Go readSuperBlock: propagate replication parse errors

Go returns an error when parsing the replication string from the .vif
file fails. Rust was silently ignoring the parse failure and using the
super block's replication as-is.

* Match Go TTL expiry: remove append_at_ns > 0 guard

Go computes TTL expiry from AppendAtNs without guarding against zero.
When append_at_ns is 0, the expiry is epoch + TTL which is in the past,
correctly returning NotFound. Rust's extra guard skipped the check,
incorrectly returning success for such needles.

* Match Go delete_collection: skip volumes with compaction in progress

Go checks !v.isCompactionInProgress.Load() before destroying a volume
during collection deletion, skipping compacting volumes. Also changed
destroy errors to log instead of aborting the entire collection delete.

* Match Go MarkReadonly/MarkWritable: always notify master even on local error

Go always notifies the master regardless of whether the local
set_read_only_persist or set_writable step fails. The Rust code was
using `?` which short-circuited on error, skipping the final master
notification. Save the result and defer the `?` until after the
notify call.

* Match Go PostHandler: return 500 for all write errors

Go returns 500 (InternalServerError) for all write failures. Rust was
returning 404 for volume-not-found and 403 for read-only volumes.

* Match Go makeupDiff: validate .cpd compaction revision is old + 1

Go reads the new .cpd file's super block and verifies the compaction
revision is exactly old + 1. Rust only validated the old revision.

* Match Go VolumeStatus: check data backend before returning status

Go checks v.DataBackend != nil before building the status response,
returning an error if missing. Rust was silently returning size 0.

* Match Go PostHandler: always include mime field in upload response JSON

Go always serializes the mime field even when empty ("mime":""). Rust was
omitting it when empty due to Option<String> with skip_serializing_if.

* Match Go FindFreeLocation: account for EC shards in free slot calculation

Go subtracts EC shard equivalents when computing available volume slots.
Rust was only comparing volume count, potentially over-counting free
slots on locations with many EC shards.

* Match Go privateStoreHandler: use INVALID as metrics label for unsupported methods

Go records the method as INVALID in metrics for unsupported HTTP methods.
Rust was using the actual method name.

* Match Go volume: add commit_compact guard and scrub data size validation

Two fixes: (1) commit_compact now checks/sets is_compacting flag to
prevent concurrent commits, matching Go's CompareAndSwap guard.
(2) scrub now validates total needle sizes against .dat file size.

* Match Go gRPC: fix TailSender error propagation, EcShardsInfo all slots, EcShardRead .ecx check

Three fixes: (1) VolumeTailSender now propagates binary search errors
instead of silently falling back to start. (2) VolumeEcShardsInfo
returns entries for all shard slots including unmounted. (3)
VolumeEcShardRead checks .ecx index for deletions instead of .ecj.

* Match Go metrics: add BuildInfo gauge and connection tracking functions

Go exposes a BuildInfo Prometheus metric with version labels, and tracks
open connections via stats.ConnectionOpen/Close. Added both to Rust.

* Match Go NeedleMap.Delete: use !is_deleted() instead of is_valid()

Go's CompactMap.Delete checks !IsDeleted() not IsValid(), so needles
with size==0 (live but anomalous) can still be deleted. The Rust code
was using is_valid() which returns false for size==0, preventing
deletion of such needles.

* Match Go fitTtlCount: always normalize TTL to coarsest unit

Go's fitTtlCount always converts to seconds first, then finds the
coarsest unit that fits in one byte (e.g., 120m → 2h). Rust had an
early return for count<=255 that skipped normalization, producing
different binary encodings for the same duration.

* Match Go BuildInfo metric: correct name and add missing labels

Go uses SeaweedFS_build_info (Namespace=SeaweedFS, Subsystem=build,
Name=info) with labels [version, commit, sizelimit, goos, goarch].
Rust had SeaweedFS_volumeServer_buildInfo with only [version].

* Match Go HTTP handlers: fix UploadResult fields, DiskStatus JSON, chunk manifest ETag

- UploadResult.mime: add skip_serializing_if to omit empty MIME (Go uses omitempty)
- UploadResult.contentMd5: only include when request provided Content-MD5 header
- Content-MD5 response header: only set when request provided it
- DiskStatuses: use camelCase field names (percentFree, percentUsed, diskType)
  to match Go's protobuf JSON marshaling
- Chunk manifest: preserve needle ETag in expanded response headers

* Match Go volume: fix version(), integrity check, scrub, and commit_compact

- version(): use self.version() instead of self.super_block.version in
  read_all_needles, check_volume_data_integrity, scan_raw_needles_from
  to respect volumeInfo.version override
- check_volume_data_integrity: initialize healthy_index_size to idx_size
  (matching Go) and continue on EOF instead of returning error
- scrub(): count deleted needles in total_read since they still occupy
  space in the .dat file (matches Go's totalRead += actualSize for deleted)
- commit_compact: clean up .cpd/.cpx files on makeup_diff failure
  (matches Go's error path cleanup)

* Match Go write queue: add 4MB batch byte limit

Go's startWorker breaks the batch at either 128 requests or 4MB of
accumulated write data. Rust only had the 128-request limit, allowing
large writes to accumulate unbounded latency.

* Add TTL normalization tests for Go parity verification

Test that fit_ttl_count normalizes 120m→2h, 24h→1d, 7d→1w even
when count fits in a byte, matching Go's fitTtlCount behavior.

* Match Go FindFreeLocation: account for EC shards in free slot calculation

Go's free volume count subtracts both regular volumes and EC volumes
from max_volume_count. Rust was only counting regular volumes, which
could over-report available slots when EC shards are mounted.

* Match Go EC volume: mark deletions in .ecx and replay .ecj at startup

Go's DeleteNeedleFromEcx marks needles as deleted in the .ecx index
in-place (writing TOMBSTONE_FILE_SIZE at the size field) in addition
to appending to the .ecj journal. Go's RebuildEcxFile replays .ecj
entries into .ecx on startup, then removes the .ecj file.

Rust was only appending to .ecj without marking .ecx, which meant
deleted EC needles remained readable via .ecx binary search. This
fix:
- Opens .ecx in read/write mode (was read-only)
- Adds mark_needle_deleted_in_ecx: binary search + in-place write
- Calls it from journal_delete before appending to .ecj
- Adds rebuild_ecx_from_journal: replays .ecj into .ecx on startup

* Match Go check_all_ec_shards_deleted: use MAX_SHARD_COUNT instead of hardcoded 14

Go's TotalShardsCount is DataShardsCount + ParityShardsCount = 14 by
default, but custom EC configs via .vif can have more shards (up to
MaxShardCount = 32). Using MAX_SHARD_COUNT ensures all shard files
are checked regardless of EC configuration.

* Match Go EC locate: subtract 1 from shard size and use datFileSize override

Go's LocateEcShardNeedleInterval passes shard.ecdFileSize-1 to
LocateData (shards are padded, -1 avoids overcounting large block
rows). When datFileSize is known, Go uses datFileSize/DataShards
instead. Rust was passing the raw shard file size without adjustment.

* Fix TTL parsing and DiskStatus field names to match Go exactly

TTL::read: Go's ReadTTL preserves the original unit (7d stays 7d,
not 1w) and errors on count > 255. The previous normalization change
was incorrect — Go only normalizes internally via fitTtlCount, not
during string parsing.

DiskStatus: Go uses encoding/json on protobuf structs, which reads
the json struct tags (snake_case: percent_free, percent_used,
disk_type), not the protobuf JSON names (camelCase). Revert to
snake_case to match Go's actual output.

* Fix heartbeat: check leader != current master before redirect, process duplicated UUIDs first

Match Go's volume_grpc_client_to_master.go behavior:
1. Only trigger leader redirect when the leader address differs from the
   current master (prevents unnecessary reconnect loops when master confirms
   its own address).
2. Process duplicated_uuids before leader redirect check, matching Go's
   ordering where duplicate UUID detection takes priority.

* Remove SetState version check to match Go behavior

Go's SetState unconditionally applies the state without any version
mismatch check. The Rust version had an extra optimistic concurrency
check that would reject valid requests from Go clients that don't
track versions.

* Fix TTL::read() to normalize via fit_ttl_count matching Go's ReadTTL

Go's ReadTTL calls fitTtlCount which converts to seconds and normalizes
to the coarsest unit that fits in a byte count (e.g. 120m->2h, 7d->1w,
24h->1d). The Rust version was preserving the original unit, producing
different binary encodings on disk and in heartbeat messages.

* Always return Content-MD5 header and JSON field on successful writes

Go always sets Content-MD5 in the response regardless of whether the
request included it. The Rust version was conditionally including it
only when the request provided Content-MD5.

* Include name and size in UploadResult JSON even when empty/zero

Go's encoding/json always includes empty strings and zero values in
the upload response. The Rust version was using skip_serializing_if
to omit them, causing JSON structure differences.

* Include deleted needles in scan_raw_needles_from to match Go

Go's ScanVolumeFileFrom visits ALL needles including deleted ones.
Skipping deleted entries during incremental copy would cause tombstones
to not be propagated, making deleted files reappear on the receiving side.

* Match Go NeedleMap.Delete: always write tombstone to idx file

Go's NeedleMap.Delete unconditionally writes a tombstone entry to the
idx file and updates metrics, even if the needle doesn't exist or is
already deleted. This is important for replication where every delete
operation must produce an idx write. The Rust version was skipping the
tombstone write for non-existent or already-deleted needles.

* Limit MIME type to 255 bytes matching Go's CreateNeedleFromRequest

* Title-case Seaweed-* pair keys to match Go HTTP header canonicalization

* Unify DiskType::Hdd into HardDrive to match Go's single HardDriveType

* Skip tombstone entries in walk_ecx_stats total_size matching Go's Raw()

* Return EMPTY TTL when computed seconds is zero matching Go's fitTtlCount

* Include disk-space-low in Volume.is_read_only() matching Go

* Log error on CIDR parse failure in whitelist matching Go's glog.Errorf

* Log cookie mismatch in gRPC Query matching Go's V(0).Infof

* Fix is_expired volume_size comparison to use < matching Go

Go checks `volumeSize < super_block.SuperBlockSize` (strict less-than),
but Rust used `<=`. This meant Rust would fail to expire a volume that
is exactly SUPER_BLOCK_SIZE bytes.

* Apply Go's JWT expiry defaults: 10s write, 60s read

Go calls v.SetDefault("jwt.signing.expires_after_seconds", 10) and
v.SetDefault("jwt.signing.read.expires_after_seconds", 60). Rust
defaulted to 0 for both, which meant tokens would never expire when
security.toml has a signing key but omits expires_after_seconds.

* Stop [grpc.volume].ca from overriding [grpc].ca matching Go

Go reads the gRPC CA file only from config.GetString("grpc.ca"), i.e.
the [grpc] section. The [grpc.volume] section only provides cert and
key. Rust was also reading ca from [grpc.volume] which would silently
override the [grpc].ca value when both were present.

* Fix free_volume_count to use EC shard count matching Go

Was counting EC volumes instead of EC shards, which underestimates EC
space usage. One EC volume with 14 shards uses ~1.4 volume slots, not 1.
Now uses Go's formula: ((max - volumes) * DataShardsCount - ecShardCount) / DataShardsCount.

* Include preallocate in compaction space check matching Go

Go uses max(preallocate, estimatedCompactSize) for the free space check.
Rust was only using the estimated volume size, which could start a
compaction that fails mid-way if preallocate exceeds the volume size.

* Check gzip magic bytes before setting Content-Encoding matching Go

Go checks both Accept-Encoding contains "gzip" AND IsGzippedContent
(data starts with 0x1f 0x8b) before setting Content-Encoding: gzip.
Rust only checked Accept-Encoding, which could incorrectly declare
gzip encoding for non-gzip compressed data.

* Only set upload response name when needle HasName matching Go

Go checks reqNeedle.HasName() before setting ret.Name. Rust always set
the name from the filename variable, which could return the fid portion
of the path as the name for raw PUT requests without a filename.

* Treat MaxVolumeCount==0 as unlimited matching Go's hasFreeDiskLocation

Go's hasFreeDiskLocation returns true immediately when MaxVolumeCount
is 0, treating it as unlimited. Rust was computing effective_free as
<= 0 for max==0, rejecting the location. This could fail volume
creation during early startup before the first heartbeat adjusts max.

* Read lastAppendAtNs from deleted V3 entries in integrity check

Go's doCheckAndFixVolumeData reads AppendAtNs from both live entries
(verifyNeedleIntegrity) and deleted tombstones (verifyDeletedNeedleIntegrity).
Rust was skipping deleted entries, which could result in a stale
last_append_at_ns if the last index entry is a deletion.

* Return empty body for empty/oversized range requests matching Go

Go's ProcessRangeRequest returns nil (empty body, 200 OK) when
parsed ranges are empty or combined range size exceeds total content
size. The Rust buffered path incorrectly returned the full file data
for both cases. The streaming path already handled this correctly.

* Dispatch ScrubEcVolume by mode matching Go's INDEX/LOCAL/FULL

Go's ScrubEcVolume switches on mode: INDEX calls v.ScrubIndex()
(ecx integrity only), LOCAL calls v.ScrubLocal(), FULL calls
vs.store.ScrubEcVolume(). Rust was ignoring the mode and always
running verify_ec_shards. Now INDEX mode checks ecx index integrity
(sorted overlap detection + file size validation) without shard I/O,
while LOCAL/FULL modes run the existing shard verification.

* Fix TTL test expectation: 7d normalizes to 1w matching Go's fitTtlCount

Go's ReadTTL calls fitTtlCount which normalizes to the coarsest unit
that fits: 7 days = 1 week, so "7d" becomes {Count:1, Unit:Week}
which displays as "1w". Both Go and Rust normalize identically.

* Add version mismatch check to SetState matching Go's State.Update

Go's State.Update compares the incoming version with the stored
version and returns "version mismatch" error if they differ. This
provides optimistic concurrency control. The Rust implementation
was accepting any version unconditionally.

* Use unquoted keys in Query JSON output matching Go's json.ToJson

Go's json.ToJson produces records with unquoted keys like
{score:12} not {"score":12}. This is a custom format used
internally by SeaweedFS for query results.

* Fix TTL test expectation in VolumeNeedleStatus: 7d normalizes to 1w

Same normalization as the HTTP test: Go's ReadTTL calls fitTtlCount
which converts 7 days to 1 week.

* Include ETag header in 304 Not Modified responses matching Go behavior

Go sets ETag on the response writer (via SetEtag) before the
If-Modified-Since and If-None-Match conditional checks, so both
304 response paths include the ETag header. The Rust implementation
was only adding ETag to 200 responses.

* Remove needle-name fallback in chunk manifest filename resolution

Go's tryHandleChunkedFile only falls back from URL filename to
manifest name. Rust had an extra fallback to needle.name that
Go does not perform, which could produce different
Content-Disposition filenames for chunk manifests.

* Validate JWT nbf (Not Before) claim matching Go's jwt-go/v5

Go's jwt.ParseWithClaims validates the nbf claim when present,
rejecting tokens whose nbf is in the future. The Rust jsonwebtoken
crate defaults validate_nbf to false, so tokens with future nbf
were incorrectly accepted.

* Set isHeartbeating to true at startup matching Go's VolumeServer init

Go unconditionally sets isHeartbeating: true in the VolumeServer
struct literal. Rust was starting with false when masters are
configured, causing /healthz to return 503 until the first
heartbeat succeeds.

* Call store.close() on shutdown matching Go's Shutdown()

Go's Shutdown() calls vs.store.Close() which closes all volumes
and flushes file handles. The Rust server was relying on process
exit for cleanup, which could leave data unflushed.

* Include server ID in maintenance mode error matching Go's format

Go returns "volume server %s is in maintenance mode" with the
store ID. Rust was returning a generic "maintenance mode" message.

* Fix DiskType test: use HardDrive variant matching Go's HddType=""

Go maps both "" and "hdd" to HardDriveType (empty string). The
Rust enum variant is HardDrive, not Hdd. The test referenced a
nonexistent Hdd variant causing compilation failure.

* Do not include ETag in 304 responses matching Go's GetOrHeadHandler

Go sets ETag at L235 AFTER the If-Modified-Since and If-None-Match
304 return paths, so Go's 304 responses do not include the ETag header.
The Rust code was incorrectly including ETag in both 304 response paths.

* Return 400 on malformed query strings in PostHandler matching Go's ParseForm

Go's r.ParseForm() returns HTTP 400 with "form parse error: ..." when
the query string is malformed. Rust was silently falling back to empty
query params via unwrap_or_default().

* Load EC volume version from .vif matching Go's NewEcVolume

Go sets ev.Version = needle.Version(volumeInfo.Version) from the .vif
file. Rust was always using Version::current() (V3), which would produce
wrong needle actual size calculations for volumes created with V1 or V2.

* Sync .ecx file before close matching Go's EcVolume.Close

Go calls ev.ecxFile.Sync() before closing to ensure in-place deletion
marks are flushed to disk. Without this, deletion marks written via
MarkNeedleDeleted could be lost on crash.

* Validate SuperBlock extra data size matching Go's Bytes() guard

Go checks extraSize > 256*256-2 and calls glog.Fatalf to prevent
corrupt super block headers. Rust was silently truncating via u16 cast,
which would write an incorrect extra_size field.

* Update quinn-proto 0.11.13 -> 0.11.14 to fix GHSA-6xvm-j4wr-6v98

Fixes Dependency Review CI failure: quinn-proto < 0.11.14 is vulnerable
to unauthenticated remote DoS via panic in QUIC transport parameter
parsing.

* Skip TestMultipartUploadUsesFormFieldsForTimestampAndTTL for Go server

Go's r.FormValue() cannot read multipart text fields after
r.MultipartReader() consumes the body, so ts/ttl sent as multipart
form fields only work with the Rust volume server. Skip this test
when VOLUME_SERVER_IMPL != "rust" to fix CI failure.

* Flush .ecx in EC volume sync_to_disk matching Go's Sync()

Go's EcVolume.Sync() flushes both the .ecj journal and the .ecx index
to disk. The Rust version only flushed .ecj, leaving in-place deletion
marks in .ecx unpersisted until close(). This could cause data
inconsistency if the server crashes after marking a needle deleted in
.ecx but before close().

* Remove .vif file in EC volume destroy matching Go's Destroy()

Go's EcVolume.Destroy() removes .ecx, .ecj, and .vif files. The Rust
version only removed .ecx and .ecj, leaving orphaned .vif files on
disk after EC volume destruction (e.g., after TTL expiry).

* Fix is_expired to use <= for SuperBlockSize check matching Go

Go checks contentSize <= SuperBlockSize to detect empty volumes (no
needles). Rust used < which would incorrectly allow a volume with
exactly SuperBlockSize bytes (header only, no data) to proceed to
the TTL expiry check and potentially be marked as expired.

* Fix read_append_at_ns to read timestamps from tombstone entries

Go reads the full needle body for all entries including tombstones
(deleted needles with size=0) to extract the actual AppendAtNs
timestamp. The Rust version returned 0 early for size <= 0 entries,
which would cause the binary search in incremental copy to produce
incorrect results for positions containing deleted needles.

Now uses get_actual_size to compute the on-disk size (which handles
tombstones correctly) and only returns 0 when the actual size is 0.

* Add X-Request-Id response header matching Go's requestIDMiddleware

Go sets both X-Request-Id and x-amz-request-id response headers.
The Rust server only set x-amz-request-id, missing X-Request-Id.

* Add skip_serializing_if for UploadResult name and size fields

Go's UploadResult uses json:"name,omitempty" and json:"size,omitempty",
omitting these fields from JSON when they are zero values (empty
string / 0). The Rust struct always serialized them, producing
"name":"" and "size":0 where Go would omit them.

* Support JSONP/pretty-print for write success responses

Go's writeJsonQuiet checks for callback (JSONP) and pretty query
parameters on all JSON responses including write success. The Rust
write success path used axum::Json directly, bypassing JSONP and
pretty-print support. Now uses json_result_with_query to match Go.

* Include actual limit in file size limit error message

Go returns "file over the limited %d bytes" with the actual limit
value included. Rust returned a generic "file size limit exceeded"
without the limit value, making it harder to debug.

* Extract extension from 2-segment URL paths for image operations

Go's parseURLPath extracts the file extension from all URL formats
including 2-segment paths like /vid,fid.jpg. The Rust version only
handled 3-segment paths (/vid/fid/filename.ext), so extensions in
2-segment paths were lost. This caused image resize/crop operations
requested via query params to be silently skipped for those paths.

* Add size_hint to TrackedBody so throttled downloads get Content-Length

TrackedBody (used for download throttling) did not implement
size_hint(), causing HTTP/1.1 to fall back to chunked transfer
encoding instead of setting Content-Length. Go always sets
Content-Length explicitly for non-range responses.

* Add Last-Modified, pairs, and S3 headers to chunk manifest responses

Go sets Last-Modified, needle pairs, and S3 pass-through headers on
the response writer BEFORE calling tryHandleChunkedFile. Since the
Rust chunk manifest handler created fresh response headers and
returned early, these headers were missing from chunk manifest
responses. Now passes last_modified_str into the chunk manifest
handler and applies pairs and S3 pass-through query params
(response-cache-control, response-content-encoding, etc.) to the
chunk manifest response headers.

* Fix multipart fallback to use first part data when no filename

Go reads the first part's data unconditionally, then looks for a
part with a filename. If none found, Go uses the first part's data
(with empty filename). Rust only captured parts with filenames, so
when no part had a filename it fell back to the raw multipart body
bytes (including boundary delimiters), producing corrupt needle data.

* Set HasName and HasMime flags for empty values matching Go

Go's CreateNeedleFromRequest sets HasName and HasMime flags even when
the filename or MIME type is empty (len < 256 is true for len 0).
Rust skipped empty values, causing the on-disk needle format to
differ: Go-written needles include extra bytes for the empty name/mime
size fields, changing the serialized needle size in the idx entry.
This ensures binary format compatibility between Go and Rust servers.

* Add is_stopping guard to vacuum_volume_commit matching Go

Go's CommitCompactVolume (store_vacuum.go L53-54) checks
s.isStopping before committing compaction to prevent file
swaps during shutdown. The Rust handler was missing this
check, which could allow compaction commits while the
server is stopping.

* Remove disk_type from required status fields since Go omits it

Go's default DiskType is "" (HardDriveType), and protobuf's omitempty
tag causes empty strings to be dropped from JSON output.

* test: honor rust env in dual volume harness

* grpc: notify master after volume lifecycle changes

* http: proxy to replicas before download-limit timeout

* test: pass readMode to rust volume harnesses

* fix store free-location predicate selection

* fix volume copy disk placement and heartbeat notification

* fix chunk manifest delete replication

* fix write replication to survive client disconnects

* fix download limit proxy and wait flow

* fix crop gating for streamed reads

* fix upload limit wait counter behavior

* fix chunk manifest image transforms

* fix has_resize_ops to check width/height > 0 instead of is_some()

Go's shouldResizeImages condition is `width > 0 || height > 0`, so
`?width=0` correctly evaluates to false. Rust was using `is_some()`
which made `?width=0` evaluate to true, unnecessarily disabling
streaming reads for those requests.

* fix Content-MD5 to only compute and return when provided by client

Go only computes the MD5 of uncompressed data when a Content-MD5
header or multipart field is provided. Rust was always computing and
returning it. Also fix the mismatch error message to include size,
matching Go's format.

* fix save_vif to compute ExpireAtSec from TTL

Go's SaveVolumeInfo always computes ExpireAtSec = now + ttlSeconds
when the volume has a TTL. The save_vif path (used by set_read_only
and set_writable) was missing this computation, causing .vif files
to be written without the correct expiration timestamp for TTL volumes.

* fix set_writable to not modify no_write_can_delete

Go's MarkVolumeWritable only sets noWriteOrDelete=false and persists.
Rust was additionally setting no_write_can_delete=has_remote_file,
which could incorrectly change the write mode for remote-file volumes
when the master explicitly asks to make the volume writable.

* fix write_needle_blob_and_index to error on too-small V3 blob

Go returns an error when the needle blob is too small for timestamp
patching. Rust was silently skipping the patch and writing the blob
with a stale/zero timestamp, which could cause data integrity issues
during incremental replication that relies on AppendAtNs ordering.

* fix VolumeEcShardsToVolume to validate dataShards range

Go validates that dataShards is > 0 and <= MaxShardCount before
proceeding with EC-to-volume reconstruction. Without this check,
a zero or excessively large data_shards value could cause confusing
downstream failures.

* fix destroy to use VolumeError::NotEmpty instead of generic Io error

The dedicated NotEmpty variant exists in the enum but was not being
used. This makes error matching consistent with Go's ErrVolumeNotEmpty.

* fix SetState to persist state to disk with rollback on failure

Go's State.Update saves VolumeServerState to a state.pb file after
each SetState call, and rolls back the in-memory state if persistence
fails. Rust was only updating in-memory atomics, so maintenance mode
would be lost on server restart. Now saves protobuf-encoded state.pb
and loads it on startup.

* fix VolumeTierMoveDatToRemote to close local dat backend after upload

Go calls v.LoadRemoteFile() after saving volume info, which closes
the local DataBackend before transitioning to remote storage. Without
this, the volume holds a stale file handle to the deleted local .dat
file, causing reads to fail until server restart.

* fix VolumeTierMoveDatFromRemote to close remote dat backend after download

Go calls v.DataBackend.Close() and sets DataBackend=nil after removing
the remote file reference. Without this, the stale remote backend
state lingers and reads may not discover the newly downloaded local
.dat file until server restart.

* fix redirect to use internal url instead of public_url

Go's proxyReqToTargetServer builds the redirect Location header from
loc.Url (the internal URL), not publicUrl. Using public_url could
cause redirect failures when internal and external URLs differ.

* fix redirect test and add state_file_path to integration test

Update redirect unit test to expect internal url (matching the
previous fix). Add missing state_file_path field to the integration
test VolumeServerState constructor.

* fix FetchAndWriteNeedle to await all writes before checking errors

Go uses a WaitGroup to await all writes (local + replicas) before
checking errors. Rust was short-circuiting on local write failure,
which could leave replica writes in-flight without waiting for
completion.

* fix shutdown to send deregister heartbeat before pre_stop delay

Go's StopHeartbeat() closes stopChan immediately on interrupt, causing
the heartbeat goroutine to send the deregister heartbeat right away,
before the preStopSeconds delay. Rust was only setting is_stopping=true
without waking the heartbeat loop, so the deregister was delayed until
after the pre_stop sleep. Now we call volume_state_notify.notify_one()
to wake the heartbeat immediately.

* fix heartbeat response ordering to check duplicate UUIDs first

Go processes heartbeat responses in this order: DuplicatedUuids first,
then volume options (prealloc/size limit), then leader redirect. Rust
was applying volume options before checking for duplicate UUIDs, which
meant volume option changes would take effect even when the response
contained a duplicate UUID error that should cause an immediate return.

* the test thread was blocked

* fix(deps): update aws-lc-sys 0.38.0 → 0.39.0 to resolve security advisories

Bumps aws-lc-rs 1.16.1 → 1.16.2, pulling in aws-lc-sys 0.39.0 which
fixes GHSA-394x-vwmw-crm3 (X.509 Name Constraints wildcard/unicode
bypass) and GHSA-9f94-5g5w-gf6r (CRL Distribution Point scope check
logic error).

* fix: match Go Content-MD5 mismatch error message format

Go uses "Content-MD5 did not match md5 of file data expected [X]
received [Y] size Z" while Rust had a shorter format. Match the
exact Go error string so clients see identical messages.

* fix: match Go Bearer token length check (> 7, not >= 7)

Go requires len(bearer) > 7 ensuring at least one char after
"Bearer ". Rust used >= 7 which would accept an empty token.

* fix(deps): drop legacy rustls 0.21 to resolve rustls-webpki GHSA-pwjx-qhcg-rvj4

aws-sdk-s3's default "rustls" feature enables tls-rustls in
aws-smithy-runtime, which pulls in legacy-rustls-ring (rustls 0.21
→ rustls-webpki 0.101.7, moderate CRL advisory). Replace with
explicit default-https-client which uses only rustls 0.23 /
rustls-webpki 0.103.9.

* fix: use uploaded filename for auto-compression extension detection

Go extracts the file extension from pu.FileName (the uploaded
filename) for auto-compression decisions. Rust was using the URL
path, which typically has no extension for SeaweedFS file IDs.

* fix: add CRC legacy Value() backward-compat check on needle read

Go double-checks CRC: n.Checksum != crc && uint32(n.Checksum) !=
crc.Value(). The Value() path is a deprecated transform for compat
with seaweed versions prior to commit 056c480eb. Rust had the
legacy_value() method but wasn't using it in validation.

* fix: remove /stats/* endpoints to match Go (commented out since L130)

Go's volume_server.go has the /stats/counter, /stats/memory, and
/stats/disk endpoints commented out (lines 130-134). Remove them
from the Rust router along with the now-unused whitelist_guard
middleware.

* fix: filter application/octet-stream MIME for chunk manifests

Go's tryHandleChunkedFile (L334) filters out application/octet-stream
from chunk manifest MIME types, falling back to extension-based
detection. Rust was returning the stored MIME as-is for manifests.

* fix: VolumeMarkWritable returns error before notifying master

Go returns early at L200 if MarkVolumeWritable fails, before
reaching the master notification at L206. Rust was notifying master
even on failure, creating inconsistent state where master thinks
the volume is writable but local marking failed.

* fix: check volume existence before maintenance in MarkReadonly/Writable

Go's VolumeMarkReadonly (L239-241) and VolumeMarkWritable (L253-255)
look up the volume first, then call makeVolumeReadonly/Writable which
checks maintenance. Rust was checking maintenance first, returning
"maintenance mode" instead of "not found" for missing volumes.

* feat: implement ScrubVolume mark_broken_volumes_readonly (PR #8360)

Add the mark_broken_volumes_readonly flag from PR #8360:
- Sync proto field (tag 3) to local volume_server.proto
- After scrubbing, if flag is set, call makeVolumeReadonly on each
  broken volume (notify master, mark local readonly, notify again)
- Collect errors via joined error semantics matching Go's errors.Join
- Factor out make_volume_readonly helper reused by both
  VolumeMarkReadonly and ScrubVolume

Also refactors VolumeMarkReadonly to use the shared helper.

* fix(deps): update rustls-webpki 0.103.9 → 0.103.10 (GHSA-pwjx-qhcg-rvj4)

CRL Distribution Point matching logic fix for moderate severity
advisory about CRLs not considered authoritative.

* test: update integration tests for removed /stats/* endpoints

Replace tests that expected /stats/* routes to return 200/401 with
tests confirming they now fall through to the store handler (400),
matching Go's commented-out stats endpoints.

* docs: fix misleading comment about default offset feature

The comment said "4-byte offsets unless explicitly built with 5-byte
support" but the default feature enables 5bytes. This is intentional
