Replace every bare `#[allow(dead_code)]` in ecstore with either a deletion or a per-item allow carrying a `reason`. Blanket allows at module, struct, and impl level silence the lint for future members too, so each is narrowed to the members that are actually dead.
Delete the dead cluster in `config/heal.rs` (`Config`, its three methods, `RUSTFS_BITROT_CYCLE_IN_MONTHS`, `parse_bitrot_config`) rather than annotate it: it has no callers and is unreachable outside the crate, and `parse_bitrot_config` would panic on its disabled path via `Duration::from_secs_f64(-1.0)`. `DEFAULT_KVS` stays, since the config registry uses it.
Correct two `reason` strings on `Checksum::new` and `PutObjReader::md5_current_hex_string`, which are methods but carried a field-only rationale.

* chore(ecstore): drop the disk dead_code blanket
Removing the blanket exposes 36 items in the lowest storage layer: 7 deleted, 29 kept with reasoned item-level allows. That is the smallest deletion share of this burn-down, and the reason is a verification limit rather than a judgement call.
disk/local.rs carries 141 `#[cfg(target_os = "linux")]` sites — the densest platform gating in the tree, because O_DIRECT and io_uring only exist there. The direct-I/O cluster (six ENV_RUSTFS_OBJECT_DIRECT_IO_* constants plus is_direct_io_read_enabled, is_direct_io_write_enabled, get_direct_io_read_threshold, direct_write_staging_capacity, direct_write_tail_split and DIRECT_WRITE_STAGING_BYTES) reads as dead on macOS purely because its production callers at local.rs:1766, 3114 and 4605 sit inside Linux-gated blocks. direct_write_staging_capacity even documents itself as "Platform-independent (no O_DIRECT), so it is unit-tested on any host".
Deleting those would leave every local check green — 4096 tests pass, clippy is clean, make pre-commit exits 0 — and break the Linux build in CI, because all four local lanes compile for aarch64-apple-darwin. Cross-checking locally is not available either: cargo check --target x86_64-unknown-linux-gnu fails in the aws-lc-sys build script for want of a Linux C cross-compiler. Their allows name the platform reason so the next reader on a non-Linux host does not repeat the investigation.
Deleted, all in files with no target_os gating at all (os.rs, disk_store.rs):
- HealthDiskCtxKey and HealthDiskCtxValue with its private log_success. Note that DiskHealthTracker::log_success is a different method of the same name and is live from cluster/rpc/peer_s3_client.rs and remote_disk.rs — the two have to be told apart by type, not by name.
- LocalDiskWrapper::new_with_health and check_id.
- os.rs file_exists and lock_destination_directory_for_path_access.
Kept with allows: DiskHealthTracker's set_faulty, mark_offline, waiting_count and last_success have test callers in remote_disk.rs, so they only look dead in the lib target. to_disk_error, remove_all and sync_dir_files are asserted by their own files' tests. The reclaim, mmap and path-cache field groups are written but never read back.
Placement follows the same rule as the earlier roots: per-method allows inside impl DiskHealthTracker and impl LocalDisk, since both are mostly live and a block-level allow would be a smaller version of the blanket this issue removes. Struct-level allows are used only where the warning covers that struct's own fields. The three cached_read_env! functions take their allow inside the macro invocation, before the fn line, because the macro forwards $(#[$meta:meta])* onto the generated item.
Verification, four lanes warning-free: default, --tests, --features rio-v2 --tests, --features test-util --tests. cargo nextest run -p rustfs-ecstore 4096 passed; clippy --lib --tests -D warnings clean; make pre-commit exit 0. The Linux lane is not covered locally and is left to CI.
Ref rustfs/backlog#1823 (step 2).
* chore(ecstore): correct two dead_code reasons in the disk root
check_valid_path and reject_symlink_components have no caller at all -
not even a test - so 'asserted by this file's tests' misreads them as
covered. Both are method wrappers over live free functions; say that
instead.

BitrotErrorType (disk/error.rs) was constructed only by its own unit test: production bitrot mismatches never flow through it (they surface as DiskError::other strings). Delete the enum, its From<BitrotErrorType> for DiskError impl, the self-test, and the api facade re-export. The facade inventory doc does not name the type, so no doc change is needed.
DiskError::SourceStalled and DiskError::CrossDeviceLink are never constructed locally — they are reachable only through wire decoding and no current node sends them. Their decode arms stay per the cross-version compatibility constraint; each variant now carries a doc comment saying exactly that so the next dead-code sweep does not re-litigate them. Their consumer arms (heal classifier, batch processor) are left untouched — the values cannot appear, so removing the arms would be unobservable, and the heal classifier is pinned by the issue as do-not-touch.
Ref rustfs/backlog#1831 (PR4).
The StorageError -> DiskError conversion dropped seven variants with
exact DiskError counterparts (FaultyRemoteDisk, DiskAccessDenied,
DriveIsRoot, IsNotRegular, VolumeNotEmpty, VolumeAccessDenied,
FileAccessDenied) into the DiskError::other fallback, degrading them to
an opaque Io error. Two of them sit on the quorum ignore-lists in
disk/error_reduce.rs, so a degraded instance would stop matching the
ignore list and count toward the dominant error in reduce_errs.
Also mirror the StorageError-side io::Error downdrill in
From<io::Error> for DiskError: recover a StorageError boxed through
From<StorageError> for io::Error instead of wrapping it as Io.
Add a round-trip identity test over every DiskError variant
(DiskError -> StorageError -> DiskError) and a boxed-StorageError
recovery test.
fix(get): give UringBackend the only fd cache for its disk (#1801)
#1801 made `StdBackend::new` always build a descriptor cache. `UringBackend`
wraps a `StdBackend` (`inner`), so under io_uring a disk ended up with TWO
`FdCache`s: the wrapper's and the inner's. `UringBackend::pread_bytes`
delegates to `inner.pread_bytes` on four fallback paths (latch-off, O_DIRECT
unsupported / error, buffered-read error), which populated `inner.fd_cache` —
but `UringBackend`'s invalidation only touches its own cache, so the inner
cache was never invalidated. For up to `FD_CACHE_TTL` (5s) after a heal/rename/
delete, a fallback read could serve the pre-mutation inode: exactly the
stale-descriptor hazard `FdCache`'s generation guard exists to close
(rustfs/backlog#1176). It also double-counted `FD_CACHE_CAPACITY` (512 fds)
against `RLIMIT_NOFILE` per disk (backlog#1178).
Fix: `UringBackend` now constructs its inner `StdBackend` with the new
`StdBackend::new_without_fd_cache`, so the wrapper owns the only cache for the
disk. The inner backend opens per read on fallback, leaving nothing
unguarded. `StdBackend::new` (standalone default) is unchanged; a private
`build(root, build_fd_cache)` holds the shared construction.
- Default (non-io_uring) path: byte-for-byte unchanged.
- io_uring path: one cache per disk, fully covered by the wrapper's
invalidation; halves the per-disk fd budget under `RLIMIT_NOFILE`.
- `RUSTFS_IO_URING_FD_CACHE` / `RUSTFS_LOCAL_FD_CACHE` semantics preserved.
- Regression test pins `new_without_fd_cache` -> no cache.
Found by a post-merge re-review of the Wave 1 GET PRs. cargo check/clippy
clean; Linux compile + the io_uring fd-cache suite deferred to CI.

Every GET fans out a `read_version` across all disks to resolve xl.meta. Each
fanout allocated an `Arc<ReadOptions>` (3 bools) plus four `Arc<String>`
(`Arc::new(x.to_string())` = two allocations each) and cloned them into every
spawned task. This trims the per-fanout allocation footprint.
- `ReadOptions` is three bools, so it is now `Copy`. The fanout drops the
`Arc<ReadOptions>` and hands each spawned task a copy; the two pre-existing
`ReadOptions::clone()` sites (set_disk/read.rs, set_disk/ops/heal.rs) stop
cloning a `Copy` type.
- The four request strings use `Arc::<str>::from(&str)` (one allocation each)
instead of `Arc::new(..to_string())` (string buffer + Arc = two each) — four
fewer allocations per fanout, transparent to the `read_version(&str)` call.
Behavior is unchanged: the fanout still spawns one task per disk (the spawn is
deliberate — `read_version_call_counter_observes_spawned_fanout` verifies the
process-global counter observes every per-disk increment across workers), quorum
/ early-stop / full-wait semantics are untouched, and no result ordering or
error handling changed.
Two larger items from the audit are intentionally NOT in this PR:
- `tokio::spawn` -> `FuturesUnordered`: the spawn is a tested, deliberate
design (cross-worker counter observation for #1309/#1314), and converting
would also change panic isolation. Left as-is.
- `vec![FileInfo::default(); N]`: `FileInfo`'s empty containers (String /
HashMap / Vec) do not allocate, so this is one `Vec` allocation, not the
per-element allocation the audit implied — not a real hot spot.
`cargo fmt`, `cargo clippy -p rustfs-ecstore --lib` (0 warnings),
`cargo check --lib --tests`, and the 26 fanout / call-counter unit tests pass
on macOS (the change is fully cross-platform).

StdBackend opened, stat'd, and access-checked the shard file on every
positioned read, so each small-object GET paid N x (open + access + fstat)
syscalls even for hot shards. UringBackend already caches descriptors
behind a generation-guarded, rlimit-bounded moka cache with full
rename/delete/heal invalidation; StdBackend had no equivalent.
Port that cache to the default backend:
- StdBackend gains an `fd_cache: Option<FdCache>` (Linux only, mirroring
UringBackend), built in `new()` behind `RUSTFS_LOCAL_FD_CACHE` (default
on) and the same `rlimit_allows_fd_cache` guard.
- pread_bytes consults the cache on the buffered path: a hit reuses the
descriptor via `dup` (one syscall, no path resolution or permission
re-check) and skips volume access; a miss opens as before, snapshots the
invalidation generation, and hands the freshly opened descriptor back
for `insert_if_fresh`, which refuses to cache if a heal/delete bumped the
generation mid-open (rustfs/backlog#1176). O_DIRECT reads keep opening
their own aligned descriptors.
- The DirectReadCopy branch switches from seek+read_exact to
`FileExt::read_exact_at`: a `dup`'d cached descriptor shares the source
descriptor's open-file offset, so a positioned read (like the mmap path's
offset argument) keeps concurrent cache hits on the same shard correct.
- The four `LocalIoBackend` invalidation methods now drop stale entries on
StdBackend. LocalDisk already calls them on rename_data/rename_file/
delete/delete_volume/close, so no new call sites are needed.
- Two tests mirror the io_uring ones: a heal rename must be hidden until
invalidate_cached_fds_under runs, and a repeated read caches exactly one
descriptor that prefix invalidation drops.
Behavior is byte-for-byte unchanged on a miss and on non-Linux; the cache
is auto-disabled only when RLIMIT_NOFILE is too low. macOS cargo check
--lib and --tests pass; Linux compile deferred to CI.

* fix(ecstore): purge the stale destination data dir on healing rename_data commits
Heal commits reuse the version's existing data_dir, so when repairing
in-place corruption (bitrot) the destination directory still exists and
holds the corrupt shard files. rename(2) cannot replace a non-empty
directory (EEXIST on XFS, ENOTEMPTY on ext4), so the commit failed on
every attempt — including all scheduler retries — and in-place bitrot was
detected and reconstructed but never repaired.
Purge the stale destination data dir (move_to_trash) before the commit
rename, for healing commits only: fresh PUTs mint a new data_dir and can
never collide, and a non-healing collision keeps failing loudly. Adds the
FileInfo::is_healing() reader for the marker set_healing() already writes.
* style(ecstore): emit the heal purge failure as a structured event
The new warning was the only sentence-style log in `rename_data`'s commit
path — it sat ten lines above `info!(event = EVENT_DISK_LOCAL_RENAME_REJECTED,
component = ..., subsystem = ...)` and interpolated its values into the
message instead of carrying them as fields, so it is invisible to any operator
query keyed on `event`.
Give it the shape the rest of the file uses: a named
`EVENT_DISK_LOCAL_HEAL_PURGE_FAILED`, `component`/`subsystem`, `dst_path` and
`error` as fields, and a short label as the message. Level stays `warn` — the
purge is best effort and the rename below fails closed — and the condition,
the branch, and the control flow are unchanged.

The RustFS event shape (`event`/`component`/`subsystem`/`result` + context,
message last) is specified only in
`.agents/skills/rustfs-logging-governance/SKILL.md`, and nothing routes a
change to it:
- `AGENTS.md`, which is what an agent actually loads by default, never
mentions logging. Its only related line is "log unknown fields at `warn`"
under Serde Safety, which is about level, not shape.
- The skill's `description` says "use when editing or reviewing RustFS logs",
so a bugfix that adds one log line in passing — how most new log sites enter
this repo — never matches it.
- `scripts/check_logging_guardrails.sh` is a blocklist: 500+ `rg -F` literals
that retire log lines which already shipped. It cannot see a newly written
one. For `crates/ecstore/src/disk/local.rs` the only check is that
`#[tracing::instrument]` is TRACE-only; `warn!`/`info!` shape is unchecked.
PR #5822 landed `warn!("heal rename_data: purging ... {:?} failed: {}", ...)`
in `disk/local.rs` — sentence-style, no fields, directly beside `info!(event =
EVENT_DISK_LOCAL_RENAME_REJECTED, component = ..., subsystem = ...)` — with
every check green. That is the gap, not an authoring mistake.
Close all three:
- `AGENTS.md`: a Logging section stating the field shape, the level policy,
the reuse-the-file's-constants rule, and that it applies to any `tracing`
macro added in passing, not only to log-focused changes.
- Skill `description`: trigger on adding or editing any `tracing` macro,
naming the single-line-added-in-passing case explicitly.
- Guardrail: assert the event shape positively on the already-governed disk
files — `error!`/`warn!`/`info!` must open with fields or a `target:`, never
a bare string. Commented-out macros are excluded; `debug!`/`trace!` stay out
of scope as targeted diagnostics. Self-test fixtures cover both directions.
`crates/ecstore/src/disk/mod.rs` carried the one live violation in that file
set (`conv_part_err_to_int`), so it is converted here; the guardrail would
otherwise fail on an untouched file.
Verification:
- `./scripts/check_logging_guardrails.sh` — passes
- Negative control: re-inserting PR #5822's exact `warn!` line into
`disk/local.rs` makes it exit 1 pointing at that line
- `cargo fmt -p rustfs-ecstore -- --check`, `cargo check -p rustfs-ecstore`
#5724 reclaimed the synthetic inline-rollback dir after a committed rename with delete_data_dir(recursive: true), which has no notion of object metadata: for unversioned objects the synthetic UUID is a fixed, publicly-known constant, so object/<rollback-dir> can simultaneously be a legitimate child key's directory, and recursively deleting it reopens the authorization bypass #5703 closed (PutObject on K destroying K/<uuid> without DeleteObject permission).
Replace the recursive pass with a file-precise one: after quorum commit, delete exactly object/<rollback>/xl.meta.bkp with a non-recursive delete on every disk whose rollback dir is not also the cleanup dir. The parent-rmdir walk removes the dir only when the backup was its sole content, so the BucketNotEmpty leak fix is preserved (#5724's regression test passes unchanged) while a child key at the same path keeps its metadata. The undo path's restore_metadata_backup now also reclaims the emptied synthetic dir, mirroring restore_delete_rollback.
Collapse per-shard blocking-pool round-trips into one spawn_blocking
pread batch when all online shards are local and mmap-read is enabled.

* fix: address rc.1 release blockers
* fix: route release guards through architecture boundaries
* fix: close remaining rc.1 regression gaps
* refactor: group multipart listing options
* fix: resolve rc.1 CI regressions
* fix(ecstore): keep bucket-config writes off the caller's stack
A bucket-config write nests incarnation resolution (which can drive legacy
migration and a peer fan-out), a full metadata load, and `save` — itself an
object PUT that pulls in the whole erasure write path. Every request that
mutates bucket config is already several futures deep, so inlining all of
that into one state machine overflows the 2MiB worker stack in debug builds.
Two CI lanes aborted with SIGABRT on this:
ILM Integration (serial)
rustfs app::lifecycle_transition_api_test::
compensation_driven_complete_multipart_upload_still_transitions
Test and Lint (swift)
rustfs-protocols::swift_metadata_persistence::
swift_metadata_writes_are_durable
Neither test file is touched by this branch and both lanes are green on
main. Stack-pointer probing showed ~780KiB consumed between
`metadata_sys::update` and the config read alone, with single hops of
363KiB (`update` -> `acquire_config_write_guard_for_incarnation`), 125KiB
and 105KiB.
Box the deep sub-futures on both read-modify-write paths (`update` /
`update_checked` and `update_config_with` / `update_config_with_checked`)
so each guard's own state machine stays small. Behaviour is unchanged;
`update` -> guard drops to 253KiB and both tests pass on the default stack.
* fix(lifecycle): unbreak restore under the bucket generation fence
The ILM lane aborted on a stack overflow before reaching these, so they
were never reported; with that fixed, four restore tests fail. All four
are green on main and none of their test files are touched by this branch.
1. RestoreObject and ListMultipartUploads hard-required
`opts.expected_bucket_incarnation_id`, but `apply_bucket_generation_guard`
deliberately leaves it unset when no guard extension is present — only the
S3 access layer installs one. Every direct caller therefore got
`InternalError: ... bucket generation guard is missing`. Resolve the
current generation instead, the way the copy path already does. The fence
is unaffected: RestoreObject still re-reads the incarnation from disk and
compares before admitting the restore, and the multipart listing is
filtered by the value it resolves.
2. `restore_expiry_snapshot_matches` (new on this branch) rejected every
restored-copy expiry whose `restore_expires` had not already elapsed.
Whether the restored copy is due to expire is the ILM evaluator's
decision, made when it emitted DeleteRestoredAction; re-deriving it in
the set layer only adds a way for a legitimate action to be rejected.
The stale-event risk it appears to guard is already covered by the
surrounding snapshot match — a re-restore rewrites `restore_expires`,
so a replayed event fails the equality check. Drop the clause; the
fifteen identity clauses are unchanged.
Fixed:
rustfs app::lifecycle_transition_api_test::
restore_object_usecase_accepts_exactly_one_of_two_concurrent_restores
restore_object_usecase_completes_suspended_null_version_in_place
restore_object_usecase_reports_ongoing_conflict
rustfs-scanner::lifecycle_integration_test serial_tests::
test_restore_chain_local_read_expiry_keeps_remote_and_allows_re_restore
Verification: the CI ILM lane filter now runs 53/53 green locally.
* chore: address review follow-ups on this branch
Four items from the adversarial review that were still open.
- Restore the assertion `test_bucket_replication_replayed_delete_marker_
preserves_source_mtime_without_source_restart` is named for. The branch
had replaced the backlog#867 mtime check with `assert_replication_
converged`, which any successful replication satisfies, and deleted the
two helpers it needed — so the regression the test exists to catch would
now pass. This matters here specifically because the branch changes the
flag feeding `replication_delete_remove_options` and routes replay
through a new file and ordering.
- Drop `read_config_no_lock_preserve_empty`: zero production callers (the
one real consumer calls the `_with_metadata` variant directly). Its test
stanza now exercises that variant, so the coverage moves to live code
rather than being deleted.
- Revert the `bytesize` bump. It is a no-op: `Cargo.lock` already pinned
2.7.0 before this branch and is untouched, so the caret range already
resolved there. Nothing in the diff uses the crate.
- Split the AGENTS.md "Adversarial Validation" policy change out of this
branch. The edit is defensible on its own, but it relaxes the review gate
that this branch has to pass, so it should land as its own PR reviewed on
its own merits rather than bundled with the change that benefits from it.
The reverted hunks are unchanged and ready to re-apply.
Not changed, deliberately: the missing-sidecar path still fails closed.
`missing_bucket_incarnation_sidecar_for_new_metadata_fails_closed` pins
that on purpose, and serving a non-authoritative Object Lock state would
be the wrong trade. The residual concern stands and is recorded in review
— a crash between the two writes in `persist_new_and_set` leaves the
bucket unloadable until DeleteBucket+CreateBucket, and the repair branches
in `migrate_legacy_metadata` and `make_bucket` are unreachable dead code
for that case. Resolving it needs the read path and the (transaction-lock
holding) repair path to be separated, which is more than a follow-up edit.
* test(ci): serialize the new bucket-incarnation tests
The five tests this branch adds around the incarnation / lifecycle fence
drive `init_bucket_metadata_sys` and `bucket_metadata_sys_of` — process-global
OnceLock state that `serial_test`'s `#[serial]` cannot protect across
nextest's process boundary — and they delete+recreate buckets, the shape that
raced into InsufficientWriteQuorum in backlog#937.
Add them to the `ecstore-serial-flaky` group in both the default and ci
profiles (nextest evaluates a named profile's own overrides list, so the
ci mirror is required). Preventive serialization only, no retries.
Not a full fix for the review comment: `bucket_delete_waits_for_config_
mutation_fence` still proves liveness with a fixed 200ms sleep plus
`assert!(!delete.is_finished())`. Turning that into readiness polling needs
a production-side signal to wait on — asserting "still blocked" is inherently
a negative. Serializing the group removes the parallel-load pressure that
makes the window fragile; the sleep itself is left for a follow-up.
* test(ecstore): pin that a drained bucket is actually deletable
`DeleteBucket`'s emptiness check is `has_xlmeta_files`, a raw scan of the
bucket directory on local disks — not an S3-level listing. So "the client
drained the bucket" and "the bucket is deletable" are two different
contracts, and only the first one was covered.
That gap is what the `S3 Implemented Tests` lane is failing on: 219 cases,
all `BucketNotEmpty` on `nuke_prefixed_buckets`, with every test body
passing. The first one is `test_versioning_obj_suspend_versions`, reported
by pytest as PASSED followed by ERROR at teardown.
Add the missing assertion for the unversioned path: PUT, client DELETE,
then assert no `xl.meta` survives and `DeleteBucket` succeeds. It passes —
which is itself a result: the plain delete path leaves no residue, so the
s3-tests failure is not there.
The versioning-suspended path is the remaining suspect (the client DELETE
leaves a null delete marker, and draining means purging it by
`versionId=null`). It is not covered here: `BucketVersioningSys` resolves
through the ambient `get_bucket_metadata_sys()` OnceLock, which this unit
env cannot set, so the bucket never actually reports as suspended. That
repro belongs at the e2e layer where a real server owns the versioning
state.
* fix(ecstore): let an explicit null-version delete purge its delete marker
Root cause of the `S3 Implemented Tests` lane: 219 cases, all
`BucketNotEmpty` on `nuke_prefixed_buckets`, every test body passing.
On a versioning-suspended bucket a client DELETE leaves a null delete
marker — correct S3 semantics, and an `xl.meta` on disk. Draining the
bucket therefore means purging that marker as `?versionId=null`, which is
what `nuke_bucket` does before `DeleteBucket`. That purge was rejected:
explicit null-version purge of the null delete marker must succeed,
got [Some(MethodNotAllowed)]
so the marker survived, and `DeleteBucket`'s emptiness check — a raw
`has_xlmeta_files` scan of the bucket directory, not an S3 listing — kept
reporting the bucket as non-empty.
The two sides of the version comparison in the batch delete loop are in
different namespaces. `goi.version_id` is the client-facing identity, where
`from_file_info` synthesizes `Some(Uuid::nil())` for a null version on a
versioned *or versioning-suspended* bucket. `version_id` is the storage
identity, where `delete_file_info_version_id` maps an explicit
`?versionId=null` to `None`. Comparing them raw makes the purge look like a
version mismatch, so `explicit_delete_marker` is false and the
`MethodNotAllowed` from the lookup is recorded as a delete failure.
This only became reachable on this branch: previously `check_opts` did not
carry `dobj.version_id`, so `set_disk_delete_creates_delete_marker` was
true, `object_lock_check_required` was false, and the lookup that produces
`MethodNotAllowed` never ran. Adding the version id to `check_opts` lit up
a comparison that was already wrong.
Normalize both sides through `delete_file_info_version_id`.
The regression test injects a real Suspended bucket-config snapshot — the
delete path reads versioned/suspended from that snapshot, not from `opts`,
so without it `from_file_info` never synthesizes the null version id and
the branch is not reached. Mutation-checked: restoring the raw comparison
fails the test with the exact `MethodNotAllowed` above.
* fix(app): drop the now-needless struct update
Reverting `crates/replication` to main removed the extra `MrfReplicateEntry`
fields, so this literal specifies every field again and `..Default::default()`
trips `clippy::needless_update` under `-D warnings`.
Caught by CI, not locally: I had run `cargo check --workspace --all-targets`,
which does not see clippy-only lints. Ran `cargo clippy --workspace
--all-targets -- -D warnings` here — clean.
* test(e2e): assert the fresh-volume classification
four_node_empty_legacy_volumes_start_as_fresh only started the cluster and
listed buckets — no assertion, so any classification path that still permits
startup left it green without proving the pre-created empty `.minio.sys`
directories were treated as fresh volumes.
Pin what that classification actually leaves behind: no buckets adopted into
the namespace, `.rustfs.sys/format.json` written on every drive, and the empty
legacy directory left untouched rather than migrated into.
* fix(bucket): apply the requested Object Lock to existing buckets
Site replication replays make-with-versioning against the destination,
carrying the source's `lockEnabled`. When the destination bucket already
exists it takes `force_create`, and the whole option-application block was
gated on `confirmed_missing` — so the call returned success while the replica
stayed unlocked. Replicated versions could then be deleted without the
retention the source enforces.
Object Lock enable is one-way, so applying it to an existing bucket is safe:
move it out of the creation-only gate, keeping `created` and versioning-only
options creation-scoped as before.
An existing authoritative bucket takes the `cache_bucket_metadata_in` branch,
which only caches, so the enable would have been dropped on restart. Persist
instead when the enable actually changed something.
Mutation-checked: restoring the creation-only gate fails the new
`force_create_enables_object_lock_on_an_existing_bucket` with "Object Lock
must be enabled on the existing bucket".
cargo nextest run -p rustfs-ecstore --lib: 3633 passed.
* fix(ecstore): box the generation-checked config mutation paths too
The earlier stack fix boxed `update` and `delete`, but an authorized
bucket-config mutation carrying an incarnation takes `update_if_incarnation`
/ `delete_if_incarnation` instead — which were still inlining the whole
resolve/load/save chain into an already-deep request future. Same overflow,
sibling path.
* fix(restore): keep the nil-version normalization the strip removed
Reverting the replication subsystem to main took `set_disk/replication.rs`
with it, but one line in that file was this branch's own fix rather than
replication work:
- self.version_id.filter(|v| !v.is_nil()) == fi.version_id.filter(|v| !v.is_nil())
+ self.version_id == fi.version_id
For a versioning-suspended object the expected version is `Some(Uuid::nil())`
while the read-back `FileInfo` carries `None`, so the raw compare reports
every suspended restore as "restored object changed before restore metadata
finalization" and the copy-back never commits. Same nil-vs-None mismatch as
the null delete-marker purge fixed earlier on this branch.
Caught by `Test and Lint (rio-v2)`, not by my local runs: the test lives in
`transition_commit_failure_tests`, gated behind `feature = "test-util"`, so
the 3633-test suite I had been running never included it. Re-ran with
`--features rio-v2,test-util`: 3722 passed.
A streaming GET holds snapshot leases on the object's data directories,
and DeleteObjects defers their physical cleanup until the leases are
released. A DeleteBucket issued inside that window passes the xl.meta
emptiness check but fails closed in the non-force delete_volume tree
removal on the leftover part files, returning BucketNotEmpty for a
logically empty bucket.
This is what intermittently failed the s3tests
test_encryption_sse_c_multipart_bad_download teardown in CI: the test
never reads its 30MiB GET body, so the server-side stream (and its
leases) stays alive until the connection drops, racing the teardown's
DeleteObjects + DeleteBucket sequence. With the body held open the
failure reproduces 5/5 locally; after this change it passes 20/20, and
the real s3-tests case passes 20 consecutive runs.
delete_volume now executes the registry-tracked pending deferred
deletions for the volume before removing the directory tree. Only data
dirs whose logical delete already committed are touched; unknown files
still fail closed with VolumeNotEmpty.
rename_all_missing_source_still_warns and rename_all_real_failure_still_warns
assert that `warn_reliable_rename_failure` emitted its WARN, but that is a
single production callsite shared with tests that call rename_all *without*
installing a subscriber — rename_all_missing_source_returns_file_not_found,
two tests above, is one of them.
tracing caches each callsite's Interest process-globally and the first thread
to reach a callsite fixes that value; while at most one dispatcher is
registered, tracing-core derives it from the registering thread's own
subscriber, and registration is once-only. When the subscriber-less sibling
wins, the callsite is cached as Interest::never() and the WARN never fires,
so the assertion sees empty output:
ordinary missing-source failures must keep the WARN, got:
Reproduced at 3/25 with `disk::os::tests::rename_all_missing_source` (both
tests), against 0/20 for the victim alone. Fixed by pinning callsite interest
inside warn_capture(), so every current and future user of that helper is
covered rather than just the two tests that happen to fail today.
pin_callsite_interest_for_test() moves from cluster::rpc::background_monitor
to a new crate-level test_tracing module: it is domain-neutral and now has
consumers in two unrelated subsystems, and disk::os should not have to reach
into a cluster::rpc test helper.
Verified: repro filter 0/30 (was 3/25); disk::os:: 0/12; cluster::rpc:: 0/12
and its poisoner pair 0/15, confirming the moved helper still holds.
Follow-up to #5438. Closes the last item in #5439.
The background tier free-version recovery walk pinned a hardcoded 60s
total wall-clock timeout that overrides every operator knob, so any
bucket whose healthy full walk exceeds 60s fails forever; the failed
run's duration was also subtracted from the next 60s tick, restarting
the walk immediately and pinning CPU and disk I/O.
- Drop the total wall-clock budget on the recovery walk
(walkdir_timeout: Duration::ZERO) and inherit the operator-tunable
drive stall budget (RUSTFS_DRIVE_WALKDIR_STALL_TIMEOUT_SECS) for
per-call progress, so hung disks still fail fast.
- Back off failed runs from completion time: 60s doubling to a 600s
cap, reset on success; never subtract the failed run's duration.
- Add RUSTFS_TIER_FREE_VERSION_RECOVERY_ENABLED (default true) to opt
out of the recovery worker on deployments with no remote tiers;
invalid values warn and fail open.

Record local read_dir entry counts and duration for live-walker ListObjects scans so wide root/prefix amplification can be measured below the cross-set merge layer.
Add a focused LocalDisk scan_dir test showing a page limit of one still observes the whole parent directory enumeration, plus metric helper coverage.
