cxymds f5463f4aa8 fix(rebalance): defer changed source cleanup (#5829) 2026-08-08 10:45:34 +08:00
Zhengchao An ab35681928 perf(ecstore): memoize bucket-incarnation fence validation under lifecycle read-lock coverage (#5782)
* perf(ecstore): memoize bucket-incarnation fence validation under lifecycle read-lock coverage

The PUT commit fence from #5648 validated the bucket incarnation with an uncached read (a distributed metadata-transaction read lock plus an EC quorum read of bucket metadata) on every PUT commit. Under 64-concurrency 4KiB PUT load this adds two quorum round-trips per PUT and the resulting lock-manager pressure produced ~1,000 client-visible 'Lock acquisition timeout' failures per 5-minute window (see rustfs/backlog#1776).

Memoize the validation per node while lifecycle read-lock coverage is continuous: bucket deletion/recreation requires the lifecycle WRITE lock, so while at least one read guard on this node has been held continuously the incarnation cannot have changed. The first fenced PUT in a coverage window performs the exact authoritative disk validation as before; overlapping PUTs reuse its result. The memo clears when the node's last guard drops or any guard observes a lost lock, so the next PUT revalidates from disk. Fence semantics are unchanged; only the redundant re-validations under continuous coverage are elided.

Also right-size the s3s footprint ratchet baselines: -1 s3_error! line from this change's error-path consolidation, and +1 s3s-importing file inherited from #5763 (crates/obs/src/telemetry/filter.rs) which landed on main without the baseline bump.

* fix(ecstore): carry the bucket fence registry through the rebalance test store

The rebalance entry test constructor landed on main after this branch was cut and needs the new field.

houseme b71483b1c8 fix(ecstore): split internal get metadata metrics (#5687)
Classify expected metadata-missing errors separately from unknown get pipeline failures and attribute internal meta-bucket reader failures to an internal_meta path instead of legacy_duplex.

This keeps scanner/data-usage metadata probes from polluting user GET/mixed failure attribution while preserving the existing read error behavior.

Zhengchao An 98d3619613 fix: address rc.1 release blockers (#5648)
* 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.

Zhengchao An 5237a4465d feat(replication): purge delete markers by the target's own version id (#5676)
* feat(replication): purge delete markers by the target's own version id

When a delete marker is replicated, the target assigns it a version id. The
purge that follows derived one from the *source* uuid instead, which is only
correct when the target mirrors source version ids. A generic S3 target does
not: the derived id addresses a version that does not exist there, so the
purge is a no-op and the replica keeps a marker the source has already
removed. Same failure class as #4401.

Record the id the target reports and address it directly on purge.

Data path, all of it driven by the object's internal metadata rather than the
`ReplicationState` wire form, which encodes positionally and cannot carry a
map:

- `rustfs-utils`: the `replication-delete-marker-version-<arn>` key family,
  plus `strip_internal_prefix_preserving_case` — ARNs are case-sensitive and
  the existing `strip_internal_prefix` lowercases.
- `ReplicationState` gains the map and a `..._corrupt` flag, both
  `#[serde(skip)]`; `ReplicatedTargetInfo` carries the per-target id.
- `persist_target_delete_marker_versions` is merge-only. A delete arriving
  over internode RPC has an empty map, so treating it as authoritative would
  let a remote disk erase an id the local disk still holds.
- `delete_object_version` copies the map into `fi.metadata` before dispatch,
  so the durable carrier crosses the wire even though the field does not.
- The keys are folded into the quorum hash through their normalized form:
  the dual internal prefixes carrying one mapping share an identity, while a
  genuine disagreement between disks still shows up as a quorum difference.
- `corrupt` (the prefixes disagreed) fails closed: skip the purge and warn
  rather than guess an id and risk destroying a live version on the target.

Ported from the rc.1 branch, which cannot merge as a whole: its MRF replay
rewrite collides with #5659/#5671/#5672/#5673 and regressed
`MRF_PENDING_CAP`. main's MRF machinery is kept; only this capability moves
across. It touches no MRF code.

Two things did not survive the port, deliberately. The branch's
`missing_is_complete` purge regression does not exist here — it came from its
own HEAD-precheck rewrite, and main's simpler path never had it. And the
branch's `MrfReplicateEntry` ordering fields are MRF-redesign scope, left
behind.

Verification: cargo fmt --all --check, git diff --check,
cargo check --workspace --all-targets, and the suites for the four touched
crates — 4070 tests, 2 pre-existing failures unrelated to this change
(`system_resolver_negative_result_reaches_the_dns_allowlist`,
`test_resolve_domain_preserves_system_resolver_error_provenance`; both are
the sandbox DNS interception, they fail on a clean checkout too).

* fix(replication): keep the layer guard happy

scripts/check_architecture_migration_rules.sh matches on text, so the doc
comments naming `rustfs_filemeta::` read as a cross-layer dependency even
though nothing imports it. Reword them; the guard passes.

* fix(replication): make the target-version cap deterministic

Two defects in this PR, both found in review.

The cap was applied while iterating a `HashMap`, so *which* 1000 entries
survived depended on iteration order. Two disks decoding the same oversized
metadata could keep different subsets, hash differently, and lose quorum —
instead of both reporting the same corruption. Collect first, then truncate
in `BTreeMap` order, which is total and identical everywhere.

And `persist_target_delete_marker_versions` discarded the `corrupt` flag from
the RPC carrier, committing a delete-marker update that looked clean while the
exact remote marker identity was unknown. It now declines to merge a corrupt
carrier. Because the helper only ever inserts, declining leaves the durable
keys already on the object untouched, which is strictly safer than writing a
mapping we cannot trust.

Residual, stated rather than papered over: corruption confined to the RPC
carrier is not persisted as a sentinel, so a later reader of an object that
carried no durable keys still sees "legacy, no mapping" rather than "corrupt".
Persisting that would need a wire-format addition; the consumer already fails
closed on any corruption it can observe.

New test: `target_delete_marker_versions_cap_is_deterministic_across_decodes`
decodes the same 1050-entry map twice and asserts both the corrupt flag and
the retained subset agree.

* fix(replication): preserve multipart source mtime (#5669)

* fix(kms): repair unopenable ciphertext and cover the Vault backends (#5668)

* Add black-box behavior tests for KMS resilience and serialization

* fix(kms): repair unopenable ciphertext across backends

Black-box testing of the KMS crate surfaced several defects that make
encrypted data permanently unreadable.

Symmetric envelopes. The Local and Vault Transit backends returned raw
cipher output from `encrypt` while `decrypt` parsed a JSON envelope, so
anything sealed through the master-key path could never be opened again.
Local also discarded the AES-GCM nonce. Both now emit the same envelope
`decrypt` consumes, matching the Static backend.

Deterministic AAD. The object layer derived AEAD additional data by
serializing a `HashMap` directly. Iteration order differs per instance,
so a context rebuilt from storage produced different AAD bytes than the
one used to seal and the object stopped opening. Ordering by key removes
that dependency, matching the Static backend's existing `context_aad`.
Objects written with the default single-key context are unaffected,
since a one-entry map has only one serialization.

Cipher in the header projection. `metadata_to_headers` recorded the SSE
mode (`AES256` / `aws:kms`), which cannot represent ChaCha20-Poly1305,
so a ChaCha-sealed object came back claiming `aws:kms` and was opened
with the wrong cipher. The cipher now travels in
`x-rustfs-encryption-algorithm` — the header the storage layer already
reads but nothing ever wrote. Objects without it fall back as before.

Also: the Static backend ignored `key_spec` and always issued 256-bit
data keys; Local `list_keys` hardcoded `truncated: false`, ignored
`marker`, and paginated over unordered `read_dir`, so a paginating
client silently saw a partial key list; and Local and Vault KV2 reported
`key_id: "unknown"` from `decrypt` despite the envelope naming the
master key.

* test(kms): cover both Vault backends and key rotation

The behavior suite ran only against Local and Static, and its own harness
documented the gap: the Vault backends had no business-capability
coverage at all. Setting `RUSTFS_KMS_VAULT_TOKEN` now adds Vault KV2 and
Vault Transit to every `for_each_backend` spec against a live server.
That lane is what surfaced the Transit envelope defect fixed in the
previous commit.

`rotate` and `versioning` are advertised only by the Vault backends, so
until now every capability-gated branch for them took the
`UnsupportedCapability` side and the working half was never asserted — a
rotation that dropped prior key versions would have gone green. The new
`behavior_rotation.rs` pins that half: material sealed before a rotation
still opens after it, repeated rotations accumulate versions rather than
overwriting a single spare, and the history survives a restart.

Two test defects fixed. `objects_round_trip_across_sizes_and_algorithms`
asserted a 1-byte object differs from its own ciphertext, which collides
once every 256 runs; the assertion now applies only where a collision is
not realistic, and small objects stay covered by the tag check and the
decrypt round-trip. `test_from_env_selects_token_file` depended on
`RUSTFS_KMS_VAULT_TOKEN` being absent from the caller's environment and
now clears it explicitly.

The snapshots directory was also removed from `.gitignore`: insta
snapshots are the assertions themselves, so leaving them untracked gives
CI nothing to compare against. Only `.snap.new` scratch files are
ignored now.

* test(kms): adapt behavior suite to current key APIs

Rebasing onto main brought four API changes the suite predates.

`DeleteKeyRequest` gained `confirm_key_id`, and immediate deletion is now
gated on the server's `allow_immediate_deletion`. Scheduled deletions pass
`None`; the four specs that destroy a key outright echo the key id back
and opt the harness config in, which is what the gate asks of a real
caller.

`LocalBackupExportRequest` gained `sanitized_config`. These specs cover
the key-material path, so they seal no configuration and pass `None`.

`KmsCacheStats` became a named struct with real hit, miss, and eviction
counters. `cache_stats_returns_an_entry_count_and_no_hit_or_miss_data`
existed to pin the old placeholder behavior — that the second tuple
element was always zero — which main has since fixed, so it is now
`cache_stats_reports_hits_and_misses_separately` and asserts the counters
actually move.

Starting the service provisions the reserved probe key, so it shows up in
listings and backup bundles. Exact-set assertions filter it through a new
`without_probe_key` helper rather than naming it, keeping those specs
about the keys they seeded.

* fix(kms): bind the AAD to the stored context bytes

Review caught that canonicalizing the AAD on decrypt breaks objects sealed
before canonicalization existed, and it was right. The AAD is the
*serialization* of the encryption context, and `x-rustfs-encryption-context`
stores that exact byte sequence: `encrypt_object` fed one `HashMap` to the
AEAD and then moved the same map into the metadata the header is written
from, so the stored string is byte-identical to the AAD the object was
sealed under. Those objects are therefore recoverable — but only while
nothing round-trips the value through a `HashMap` and re-serializes it.

Recomputing sorted AAD on decrypt would have turned a readable object into
a permanently unreadable one. The previous behavior was worse than the
first analysis credited: it did not merely fail intermittently, it made
the failure deterministic.

`EncryptionMetadata` now carries `context_aad`, the bytes the object was
actually sealed with. Encryption records what it fed the AEAD, the header
projection stores those bytes verbatim (and preserves a legacy ordering
across a re-projection rather than rewriting it into sorted form), and
`headers_to_metadata` carries the stored string through untouched. Both
decrypt paths, SSE-KMS and SSE-C, prefer it and fall back to canonical
serialization only when no stored serialization exists. Canonicalization
still applies to everything newly sealed, so the original ordering bug
cannot recur.

Two tests pin this: a legacy record whose sealed bytes are non-canonical
must survive a full header round trip unchanged, and a context header
rewritten to an equivalent-but-reordered serialization must fail
authentication rather than silently re-deriving a working AAD. Both were
mutation-checked against the reinstated bug on each side.

Also from review: the lifecycle churn test asserted only that every
request was accounted for, which holds whether the state gate exists or
not, so both branches are now pinned deterministically after the churn
(asserting `refused > 0` on the concurrent phase would only trade the hole
for a scheduling flake). And the Local and Vault KV2 envelopes compare
`encryption_context` without authenticating it — `DekCrypto` seals only
the plaintext — which is now documented at both sites; closing it needs a
versioned envelope, since existing ciphertext was sealed without AAD.

Zhengchao An 63e57378d6 fix(ecstore): never cache fabricated bucket metadata as authoritative (#5307)
BucketMetadataSys::get_config lazily fabricated a default BucketMetadata
(object-lock off) for any bucket whose .metadata.bin was ConfigNotFound and
cached it in the map that the map-only, fail-closed metadata_sys::get()
serves. The object-lock batch-delete gate (object_lock_delete_check_required,
backlog#929 / #4297) treats that map as authoritative, so a metadata miss
became a cached "no lock" answer: a versioning peek could poison the cache
and let delete_objects skip the per-object retention/legal-hold stat. The
same fabrication raced make_bucket (lost update overwriting freshly
persisted lock-enabled metadata) and let the 15-minute refresh loop replace
good cached metadata on a transient quorum dip.

Production changes:
- get_config caches only metadata actually read from disk; misses are
  recorded in a bounded negative cache (30s TTL, 10k entries, invalidated by
  set()) so repeated lookups for metadata-less names cost no extra
  namespace-lock + erasure-set fanout (reachable pre-auth via CORS
  preflight and per-key in DeleteObjects).
- concurrent_load never lets a fabricated default REPLACE an existing map
  entry; startup insert-if-vacant behavior for legacy buckets is preserved.
- delete_objects and new_ns_lock resolve dist-erasure, versioning, and the
  object-lock gate from the set's own instance context (backlog#1052)
  instead of the ambient facade, so a second in-process instance (or, in
  tests, another test's transient DistErasure window) cannot reroute
  locking onto an empty dist locker list or answer with the wrong
  instance's bucket state.

Test-isolation changes (the bug that surfaced all of the above: the
delete_objects lock-gating test failed deterministically when sharing a
process with the lifecycle env tests):
- The MinIO-migration test builds on an isolated InstanceContext instead of
  registering soon-deleted disks in the shared bootstrap registry.
- The cached lifecycle env re-registers its disks on every use, surviving
  other serial tests' reset_local_disk_test_state.
- Hermetic SetDisks helpers gain isolated-context variants pinned to plain
  erasure; tier-free non-serial test modules use them, guard-based
  SetupTypeGuard tests stay on the bootstrap context.
- Three deterministic pin tests (nextest-safe) cover the caching contract,
  the delete gate resolution source, and the ns-lock resolution source.

Verification:
- cargo test -p rustfs-ecstore --lib -- --exact <4-test combo from the
  report> (previously failing, now green)
- cargo test -p rustfs-ecstore --lib: 3169 passed / 0 failed across
  repeated runs; cargo fmt --check and cargo clippy --lib --tests clean
- Adversarial validation (high-risk tier, all seven roles) run per
  AGENTS.md; all findings fixed or rebutted with evidence

cxymds b0c6c4cbce fix(storage): resolve erasure parity per pool (#4977)
* fix(filemeta): add state-aware file info validation

* fix(filemeta): validate shard arithmetic and delete paths

* fix(ecstore): add fallible erasure construction

* fix(ecstore): resolve storage parity per pool

* fix(storage): report heterogeneous erasure layouts

* fix(admin): publish prepared storage config atomically

* fix(storage): harden per-pool parity boundaries

* fix(storage): address pre-PR validation findings

* test(ci): fix strict-topology validation fixtures

* fix(heal): preserve delete markers during repair

* refactor(filemeta): drop unused ValidatedFileInfo witness

ValidatedFileInfo wrapped an unread `_file_info` reference alongside an `Option<ValidatedErasureLayout>`, but only the layout was ever consumed. Return the layout directly from `FileInfo::validate` so the sole production consumer (`LocalDisk::check_parts`) and the two unit tests read it without the extra witness type and lifetime.

No behavior change.

* fix(filemeta): keep compressed and MinIO-migrated tiered objects readable

The new decode-path validation rejected several legitimate on-disk shapes that older RustFS and MinIO-migrated data carry, turning readable objects into FileCorrupt:

- Compressed objects written with an unknown upload size persist a negative per-part actual_size (the documented "unknown size" sentinel that ObjectInfo::get_actual_size already tolerates). validate_collection_contents rejected it via usize::try_from; now a negative actual_size skips shard validation and only real, non-negative sizes are checked.
- MinIO-migrated objects transitioned to a versioned remote tier store the tier version id as a UUID string, not 16 raw bytes. MetaObject::into_fileinfo returned FileCorrupt (main tolerated it as None), making all versions of the object unreadable; MetaDeleteMarker free-version records took a Some(nil) sentinel path with the same effect, which also breaks free-version expiry (remote-tier leak). Both now decode through a shared transitioned_version_id_from_meta_sys helper: 16 raw bytes or a UUID string are accepted, anything else is tolerated as None instead of failing the read.

Regression tests updated to assert the readable/compat behavior, with new tests covering MinIO string-form recovery.

* fix(scanner): build the delete-marker test fixture without erasure geometry

get_size_counts_delete_markers_separately_from_versions built its delete marker with `FileInfo::new(object, 1, 1)`, which attaches erasure geometry (data=1/parity=1/distribution). This PR classifies versions by shape via `is_storage_delete_marker()` (no geometry) rather than the raw `deleted` flag, so a geometry-bearing "delete marker" is correctly serialized as a purge-pending payload Object and counted as a version — CI saw summary.versions=3, expected 2.

Real delete markers carry no erasure geometry (delete paths build them as `FileInfo { deleted: true, ..Default::default() }`), so construct the fixture the same way. It then classifies as a storage delete marker and the counts (versions=2, delete_markers=1) hold. This keeps the PR's more-correct classification, which prevents a purge-pending object's geometry from being dropped when serialized as a bare delete marker.

* docs(changelog): note per-pool parity fix and storage-class startup upgrade caveat

Records the #4801 per-pool erasure parity fix under Fixed, and documents the upgrade behavior where a persisted storage class that a small or heterogeneous pool cannot satisfy now fails startup — with the RUSTFS_STORAGE_CLASS_STANDARD recovery steps. Docs-only; covers R4 from the on-disk compatibility audit.

* fix(heal): report parity from erasure geometry, not is_valid()

heal_object set HealResultItem.parity_blocks via `if lfi.is_valid()`, which was missed by the migration of the other quorum/metadata predicates. With the new `is_valid()` semantics (full payload validation; delete markers now return false), a delete marker or a geometry-bearing version with a benign collection quirk would misreport parity as the pool default instead of its own. Use `has_valid_erasure_geometry()` — the narrow "does this carry erasure geometry" predicate the rest of the migration uses — so reporting matches the object's actual layout. Reporting-only; no data-path change.

* fix(filemeta): do not silently serialize a non-canonical deleted FileInfo as an Object

`From<FileInfo> for FileMetaVersion` classifies by `is_storage_delete_marker()` (shape), which correctly routes canonical delete markers to Delete and purge-pending payloads (deleted=true with real erasure geometry) to Object. But a `deleted` FileInfo that is neither a canonical marker nor a valid erasure payload would silently serialize as a zero-geometry MetaObject that later fails `validate_for_metadata_read`. Write paths validate first (`validate_for_erasure_write` / `validate_for_metadata_read`), so this is a caller bug; `From` is infallible, so surface it with a structured `warn!` on the malformed branch instead of writing corrupt metadata silently. Legitimate purge-pending objects (valid geometry) are unaffected — the guard only fires for `deleted && !has_valid_erasure_geometry()`.

* test(filemeta): assert real historical xl.meta versions pass metadata-read validation

Empirical companion to the code-reasoned decode-tolerance invariants (docs/architecture/erasure-coding.md §11) and the rolling-upgrade / MinIO-migration compatibility concern: the tightened `validate_for_metadata_read` runs on every local disk read and peer-RPC-decoded FileInfo, so it must accept every version of real historically-written xl.meta, never reject it as FileCorrupt.

Loads five real fixtures — MinIO small-inline, MinIO versioned (two object versions + a delete marker), MinIO large multipart, a legacy V1 (xl.json-derived) object, and a legacy meta_ver 2 object — decodes every version with parts materialized, and asserts validate_for_metadata_read() is Ok for each. Reverting the tolerant handling (delete-marker shape, legacy per-part checksums, string/short transitioned-versionID, negative actual_size) turns this red.

* fix(ci): remove duplicate storage test re-exports

Zhengchao An 7f5873dac8 fix(ecstore): resolve erasure parity per pool (#4801) (#5015)
* fix(ecstore): add fallible erasure construction

(cherry picked from commit bd148b20f7)

* fix(ecstore): resolve storage parity per pool

(cherry picked from commit c05c2cb24b)

* fix(ecstore): keep carved per-pool parity core self-contained on main

Fixups so the cherry-picked fallible-erasure + per-pool-parity core builds standalone on current main without the excluded scope-creep commits:
- runtime/sources.rs: re-add backend_storage_class_parities (removed by the per-pool commit; its rebalance caller was updated in an unrelated reporting commit that was left out). Reimplemented over the snapshot API, behavior-identical.
- config/mod.rs: rename the storage-class publish test module (main independently added a mod tests, so the cherry-pick collided).
- rustfs storage_api.rs + startup_storage.rs: route the storage-class ENV consts through the startup storage facade and use a local const for the erasure-set-drive-count env name, satisfying the layer/facade guardrail (main's guardrail is stricter than when the core was authored).

* fix(ecstore): use struct-init in erasure test helper to satisfy clippy field_reassign_with_default

The cherry-picked fallible-erasure commit's `erasure_with_invalid_dimensions` test helper built `Erasure` via `default()` then reassigned fields, which trips `clippy::field_reassign_with_default` under `-D warnings` (only surfaced by `--all-targets`, which lints test code). #4977 fixed this in a later commit that was not part of the carved core. Use struct-init with `..Default::default()`, matching #4977's final form.

* fix(rustfs): gate the test-only storage-class ENV facade re-export behind cfg(test)

The ENV constants (INLINE_BLOCK_ENV/OPTIMIZE_ENV/RRS_ENV/STANDARD_ENV) re-exported through the startup storage facade are only consumed by a #[cfg(test)] test in startup_storage.rs, so in a non-test lib build the re-export is unused and trips -D unused-imports under clippy --all-targets. Gate it with #[cfg(test)], matching #4977's final form.

Zhengchao An 04bfd48eb1 fix(ecstore): invalidate metadata cache after ILM transition persists (#4951)
A duplicate transition task admitted after the winner released its
in-flight claim (#4839) re-reads the version before uploading, but on
unversioned buckets that read could hit a stale pre-transition entry in
the 2s-TTL GET metadata cache: transition_object never invalidated the
cache after delete_object_version persisted transition_status=complete
and freed the local data. The stale hit defeated the TRANSITION_COMPLETE
early-return, so the duplicate streamed the already-deleted local data
to the remote tier (NotFound reader errors + rejected duplicate tier
PUT with UnexpectedContent).

Invalidate the cache right after the transitioned metadata is persisted,
matching the other metadata-mutating paths, and add a regression test
that runs a duplicate transition against an already-transitioned version
and asserts no second tier upload and unchanged remote object metadata.

Fixes #4827
