houseme 750e5d15eb feat(checksums): add native S3 additional checksum support (#4805)
* feat(rio): wire XXHash3/64/128 and SHA-512 into ChecksumType (S2)

Add the AWS 2026-04 additional checksum algorithms as base types in
rustfs-rio's ChecksumType, covering every dispatch site (key, raw_byte_len,
hasher, Display, from_string_with_obj_type, BASE_CHECKSUM_TYPES) so no path
silently strips them. Derive BASE_TYPE_MASK from BASE_CHECKSUM_TYPES as the
single source of truth, allocate the new base-type bits append-only above
bit 9 to preserve the on-disk varint format, and add streaming hashers whose
digest uses the S3 canonical big-endian encoding (seed 0).

The new algorithms are COMPOSITE-only: an explicit FULL_OBJECT request is
rejected and they are never routed through add_part()/can_merge(). A
round-trip guardrail test asserts every base type survives all dispatch
sites, failing loudly if a future algorithm is added but a match arm or the
mask is forgotten.

* test(rio): pin XXHash/SHA-512 digests to official vectors, big-endian (S3)

Lock the byte order and seed of the new algorithms against the OFFICIAL
upstream xxHash / SHA-512 empty-input test vectors (XXH3-64, XXH64, XXH3-128,
SHA-512), in big-endian, so the stored and echoed checksum is byte-for-byte
identical to what AWS SDKs (awscrt) compute — the interop correctness this
feature hinges on. Add a non-empty regression lock (official "fox" vectors)
that also asserts the encoded field is the standard-base64 of the raw digest.

* test(rio): lock on-disk checksum round-trip and forward-compat degrade (S8)

Cover the xl.meta varint (de)serialization for the new algorithms:
to_bytes() -> read_checksums() must recover the value under the Display key
for XXHASH3/64/128 and SHA512. Pin the rolling-upgrade contract that a node
reading a future, unknown base-type bit degrades safely — skips the entry and
returns without panicking or mis-decoding a length. Combined with the
append-only bit allocation from S2, this protects mixed-version clusters.

* feat(head): echo XXHash/SHA-512 additional checksums on HeadObject (S5)

HeadObject with x-amz-checksum-mode: ENABLED now returns the XXHash3/64/128
and SHA-512 checksums that S3 stored, closing the head_object gap in #4800.
s3s HeadObjectOutput has no typed field for these, so they are emitted as raw
response headers via response.headers (the same mechanism RustFS already uses
for tagging-count), keyed by ChecksumType::key(). The existing five typed
algorithms are unchanged. Also carries the Cargo.lock update for the
xxhash-rust dependency introduced in S2.

* fix(checksums): fail-closed on unknown checksum algorithm (S7)

A. Harden unknown/unsupported checksum algorithms to fail closed instead of
   panicking. ChecksumMode::base() in the outbound S3 client
   (crates/ecstore/src/client/checksum.rs) previously did
   `panic!("enum err.")` for any mode without a concrete base algorithm (e.g.
   a bare ChecksumFullObject flag); it now falls back to ChecksumNone. Added
   unit tests proving base() never panics and hasher() returns Err for
   unsupported modes. rustfs-checksums FromStr already returns Err on unknown
   names; added a regression test asserting garbage/unknown names fail closed.

B. Extend rustfs-checksums ChecksumAlgorithm with the AWS 2026-04 additional
   algorithms Sha512/Xxhash3/Xxhash64/Xxhash128. Updated FromStr, as_str,
   into_impl, name constants, the x-amz-checksum-* header constants and the
   HttpChecksum impls. Byte order/seed matches the server-side rustfs-rio
   spec: xxh3/xxh64 as u64 big-endian (8 bytes, seed 0), xxh128 as u128
   big-endian (16 bytes), sha512 via sha2::Sha512. Added tests validating each
   digest against a direct library computation. MD5 stays intentionally
   rejected (PR #4513) and is left untouched.

C. crates/ecstore/src/client/checksum.rs ChecksumMode is enumset repr="u8"
   with 7 variants already consuming 7 bits; adding the 4 new algorithms would
   overflow u8 and require a breaking repr change, so ChecksumMode is left
   unchanged. The new algorithms are available through the rustfs-checksums
   ChecksumAlgorithm path.

* feat(get,put): echo XXHash/SHA-512 checksums on GetObject and PutObject (S5-GET, S4)

Complete the additional-checksum round-trip so AWS SDKs can verify integrity on
download and confirm it on upload:

- GetObject with x-amz-checksum-mode: ENABLED now returns XXHash3/64/128 and
  SHA-512 checksums (the download-side path SDKs auto-verify). The values flow
  from build_get_object_checksums through GetObjectOutputContext into
  finalize_get_object_response and are emitted after wrap_response_with_cors.
- PutObject echoes the server-computed additional checksum on its response,
  captured at the want_checksum set points before opts is moved.

Both reuse a single centralized helper, inject_additional_checksum_headers,
which HeadObject now also uses. This is the ONLY place that emits these headers,
so when s3s gains typed fields for these algorithms the migration is one spot
(fill the typed field, drop the insert) with no risk of duplicate headers.

The five s3s-typed algorithms are unchanged. Trailing-checksum PUT echo (value
lands after the body) is left for e2e coverage in S10.

* feat(multipart): support XXHash/SHA-512 composite multipart checksums (S9)

Make multipart uploads work end-to-end for the composite-only algorithms
(XXHash3/64/128, SHA-512):

- complete_part_checksum previously returned the outer None for any algorithm
  outside the five typed ones, which failed CompleteMultipartUpload with
  InvalidPart. It now accepts any valid base type with no double-check value
  (Some(None)) — mirroring the missing-value path of the typed algorithms —
  since s3s CompletePart has no field to carry a client-supplied per-part
  value and the part was already verified server-side at UploadPart. Genuinely
  unset/invalid types are still rejected.
- The existing COMPOSITE assembly (Checksum::new_from_data over the
  concatenated per-part raw digests; full_object_requested() is false so
  add_part() is correctly bypassed) already works for these algorithms via the
  S2 wiring. A rio test locks the assembly and that add_part refuses them.
- UploadPart and CompleteMultipartUpload echo the new-algorithm checksum on
  their responses via the shared inject_additional_checksum_headers helper
  (now pub(crate)), since s3s has no typed output field.

* feat(rio): add MD5 as an additional checksum (x-amz-checksum-md5) (S6)

Wire MD5 into ChecksumType as an additional (flexible) checksum, distinct from
the legacy Content-MD5 / ETag path: header x-amz-checksum-md5, 16-byte digest,
COMPOSITE-only, md-5 hasher. Pinned to the official empty-input MD5 vector.

Thanks to the single-source-of-truth wiring from S2, every dispatch site
(GetObject/HeadObject/PutObject echo, multipart complete_part_checksum and the
COMPOSITE assembly) picks MD5 up automatically via base()/key()/the catch-all
arm — no handler changes needed. Tests are extended to cover MD5 across them.

Coordination with #4513: that PR made the OUTBOUND rustfs-checksums client
reject "md5" so it could never silently fall back to CRC32. This change is on
the server-side rio path and never falls back — it implements MD5 correctly
rather than substituting another algorithm — so the #4513 intent is preserved,
and the outbound client keeps rejecting md5 (S7).

* perf(rio): drop per-request to_uppercase alloc in checksum parsing (S11)

from_string_with_obj_type ran alg.to_uppercase() on every checksummed request,
allocating a String just to compare against a fixed set of algorithm names.
Replace it with eq_ignore_ascii_case, which is allocation-free and, for the
ASCII algorithm names involved, exactly equivalent. A test locks that
case-insensitivity, the CRC64NVME full-object assumption, composite-only
FULL_OBJECT rejection, and unknown/empty handling are all unchanged.

The other S11 notes are intentionally not acted on: the Phase-0 header scan is
N/A (we chose full support over rejection, so there is no reject guard), and
parallelizing the serialized hash passes is deferred pending a measured need.

* refactor(checksums): collapse 5 duplicated response-checksum loops into one

Review of the accumulated commits found the same "iterate decrypted checksums,
match five typed algorithms, drop the rest" loop copy-pasted across five
response paths (GetObject, HeadObject, GetObjectAttributes object-level and
part-level, CompleteMultipartUpload). That was patch-on-patch duplication.

Collapse it into a single source of truth:
- rustfs-rio gains ChecksumType::is_s3s_typed() — the one place that defines the
  five-typed vs additional-algorithm split.
- object_usecase gains ResponseChecksums + classify_response_checksums(), which
  performs the typed/extra split once. All five call sites now destructure its
  result; additional_checksum_echo_pairs() also uses is_s3s_typed() instead of a
  hand-rolled five-way comparison.

Behaviour is unchanged (GetObjectAttributes still cannot surface the additional
algorithms — an s3s XML-body limitation, now documented in one spot). One pass
over the map; extra pairs pushed only when a new-algorithm checksum is present.

* test(checksums): unit tests for classifier/echo helpers + fix unused import

Add direct unit tests for the refactored single-source-of-truth helpers:
- rio ChecksumType::is_s3s_typed() — exhaustive typed-vs-additional split, and
  that flags (FULL_OBJECT/MULTIPART) on a base type don't change classification.
- object_usecase classify_response_checksums() — typed fields vs `extra` headers,
  the checksum-type marker, and empty input.
- additional_checksum_echo_pairs() — echo pair only for additional algorithms,
  none for the five typed ones, none for None.
- inject_additional_checksum_headers() — writes all pairs; empty is a no-op.

Also drop the now-unused AMZ_CHECKSUM_TYPE import in multipart_usecase.rs left
by the classifier refactor (would fail the -D warnings gate).

* test(e2e): integration test for XXHash/SHA-512/MD5 additional checksums (S10)

Permanent verify-on-write integration test in the e2e suite for the AWS 2026-04
additional algorithms. aws_sdk_s3 has no typed builder for these, so the
x-amz-checksum-<algo> header is injected via mutate_request (value from
rustfs-rio, byte-for-byte identical to awscrt). Uses a client with automatic
checksum calculation disabled (request_checksum_calculation=WhenRequired) so the
injected header is the only checksum on the wire. For each of XXHash3/64/128,
SHA-512 and MD5: a correct value is accepted and the object stored intact; a
mismatched value is rejected with BadDigest and nothing is stored.

Verified passing locally (1 passed) alongside a boto3+awscrt round-trip that
additionally confirms the HEAD/GET header echo (14/14).

* style(get): allow too_many_arguments on finalize_get_object_response

finalize_get_object_response to 8 args and tripping clippy::too_many_arguments
under CI's `-D warnings`. Add the same #[allow] the sibling GET helpers already
carry; no behavior change.

houseme 1553dc3f62 Address P2 follow-ups from the 2026-07-10..12 merged-PR review (backlog#1210-1220) (#4783)
* fix(obs): open cleaner compression source with O_NOFOLLOW

The compressor opened the source log via File::open, which follows a
symlink at the final path component. Between the scanner selecting a
regular file and this open, an attacker with write access to the log
directory could swap the entry for a symlink (TOCTOU) pointing at, say,
/etc/shadow, whose contents would then be copied into an archive. Open
the source with O_NOFOLLOW on Unix so such a swap fails with ELOOP; the
temp/archive path already refused symlinks, this closes the source side.

* fix(obs): recompress instead of trusting leftover cleaner archives

archive_header_ok only checked the first 2-4 magic bytes before treating
an existing .gz/.zst as a completed prior result and letting the caller
delete the source log. A file with valid magic but a truncated or forged
body passes that check, so an attacker with write access to the log
directory (or a crashed prior run) could plant such a stub and make the
cleaner delete the real log without ever producing a usable archive —
silent audit-data loss.

Chosen fix: stop trusting cross-process leftovers entirely and always
recompress the source in this pass, rather than fully decoding every
leftover to validate it. Full-decode validation would add real CPU cost
and decode-bug surface for a rare crash-recovery case; the existing
atomic create_new+rename already overwrites whatever sits at the archive
path (a planted symlink is replaced, never followed) with a freshly
written, fsync'd archive, so a partial/forged leftover can never gate
source deletion. This is the lowest-regression option.

* fix(object-data-cache): cap memory-gate reservation at cache growth headroom

The memory gate subtracts `admitted_since_refresh` from the snapshot's
available bytes so a burst arriving faster than the 5 s refresh cannot
over-allocate. That counter is GROSS: it only rolls over on the refresh and
never rolls back when a fill is later evicted, cancelled, or loses the
invalidation race. Under sustained high-throughput churn (net footprint flat
and far below `max_capacity`) the raw counter balloons past the memory the
cache actually holds, so `effective_available` collapses and the gate reports
false memory pressure — skipping the hottest fills with SkippedMemoryPressure
until the next 5 s refresh. This only lowers hit rate; it never returns wrong
data and self-heals each refresh.

Fix direction 1 (minimal regression): cap the reservation deduction at the
cache's own growth headroom (`max_capacity - weighted_size()`) instead of
letting the unbounded gross counter shrink the system-available budget. The
cache can never hold more than `max_capacity`, so a burst adds at most that
headroom of real memory before moka evicts to stay bounded (net-zero churn
beyond that point) — capping the deduction there keeps the reservation honest
without treating gross churn as growth. Chosen over net-accounting (direction
2, releasing bytes on every failure/cancel/eviction path) because that only
plugs the leak on failed fills and would not address the core defect: churn of
*successful* insert/evict fills over the 5 s window. It also touches only the
gate plus one call site rather than every failure path in moka_backend.

The cap only ever raises `effective_available`, so real memory pressure (a low
snapshot at refresh) still suppresses fills; when the cache is at capacity the
headroom is 0 and the deduction vanishes, correctly reflecting net-zero churn.
`MokaBackend` now stores `max_capacity` and passes the live headroom into
`allows_fill`. Adds targeted gate tests: gross churn far above headroom no
longer falsely suppresses, yet the reservation still bounds a burst while the
cache can genuinely grow.

* test(ecstore): assert native O_DIRECT path runs in uring read test

uring_preserves_o_direct_for_eligible_reads only compared bytes through
LocalDisk::read_file_mmap_copy. On a filesystem that rejects O_DIRECT the
read silently degrades to the buffered StdBackend fallback and the byte
check still passes, so the test could go green without the native
read_at_direct path ever executing -- a vacuous pass.

Add a per-disk native_direct_reads counter on UringBackend, incremented
only when pread_uring_direct completes, and rebuild the test to drive a
real UringBackend's pread_bytes and assert the counter is non-zero (every
eligible read went through the native tier). When io_uring or O_DIRECT is
unavailable on the host filesystem (restricted CI runners, tmpfs), the
test skips loudly via eprintln instead of asserting a tautology, while
still checking byte-correctness on whatever tier served the read.

The counter also gives a gray release a positive signal that the O_DIRECT
tier is serving reads, not just a fallback count.

Refs rustfs/backlog#1213

* fix(ecstore): warn + count read-time EINVAL on native O_DIRECT reads

classify_direct_read_error is only reached from the read side: the
O_DIRECT open in pread_uring_direct already succeeded (an open-time
refusal is handled earlier as DirectOpenError::ODirectRefused). So an
EINVAL/EOPNOTSUPP arriving here is a read-time error on an fd the kernel
accepted for O_DIRECT -- far more likely an alignment bug in the aligned
read path than an unsupported filesystem. The old code latched the disk's
native path off with only a once-per-disk debug trace, hiding a potential
correctness regression behind a silent buffered-read downgrade.

Diagnostics only: the fallback behaviour is unchanged (the native path is
still latched off and the caller still reads via StdBackend). This adds a
rustfs_io_uring_direct_read_einval_total counter and promotes the
once-per-disk trace from debug to warn so an operator can see an alignment
regression instead of an unexplained latency/CPU shift.

* docs(ecstore): document data-blocks-first default and its tail-latency cost

DEFAULT_RUSTFS_GET_DATA_BLOCKS_FIRST_READER_SETUP is true and must stay
true: deferred-parity is the deliberate, already-rolled-out full-object
GET default from backlog#1159/#923. Flipping it back to false in code
would silently revert that rollout for every deployment that has not set
the env var, so this commit only documents -- no behaviour change.

The added notes explain what data-blocks-first does (schedule data shards
up front, engage parity lazily on a missing/corrupt data shard), the known
trade-off (parity is engaged late, so a slow-but-not-dead data drive
raises GET p99 because the faster parity shards are not raced against it
until a data shard is declared missing), and the operational rollback
switch (RUSTFS_GET_DATA_BLOCKS_FIRST_READER_SETUP=false), which is
intentionally an env override rather than a code default change.

No metric was added: the low-risk observability hook for "slow data drive
engaged deferred parity" would live at the deferred-stripe engage point,
which is out of this file's scope; this change stays documentation-only to
avoid touching the hot GET path.

* docs(ecstore): document wide-directory walk stall hazard and tuning

list_dir enumerates a whole directory in one os::read_dir call (count =
-1), and the walk caller bounds that entire enumeration with the per-read
stall budget (default 5s) as if it were a single read. For a wide, flat
prefix -- one directory holding millions of immediate children -- a single
readdir can exceed the budget on a healthy disk, trip DiskError::Timeout,
and surface as a ListObjects 500 quorum failure though the drive is fine
(a #2999 sub-class).

This is documented, not rewritten: turning the one-shot readdir into a
streaming/batched enumeration that refreshes the stall deadline between
chunks is an architecture-level change with high regression surface
(ordering, the count contract, quorum merge) and belongs in a separate
follow-up. The supported mitigation today is operational, so the comments
point wide-directory deployments at RUSTFS_DRIVE_WALKDIR_STALL_TIMEOUT_SECS
and the high-latency drive-timeout profile, which widen the budget with no
code change. Notes were added at list_dir, the scan_dir call site, and
get_drive_walkdir_stall_timeout. No behaviour change.

* docs(ecstore): document consumer-peek vs producer-stall coupling

In list_path_raw the consumer's peek_timeout is drawn from the same source
and same value (walkdir_stall_timeout, default 5s) as the producer-side
walk stall budget, but the two measure different things: the producer
stall bounds a single drive read, while the consumer peek bounds the gap
between two ADJACENT entries arriving from a reader. Because they share a
value, the consumer cannot wait meaningfully longer for the next entry
than the producer is allowed to spend producing one. Walking a region
dense with non-listable internal items can make a HEALTHY drive miss the
budget between visible entries; the consumer then declares it stalled and
detaches it, dropping a good drive from the merge and capping the "large
prefix succeeds" guarantee.

Documented, not decoupled: giving the consumer peek an independent,
strictly-larger budget would cut these false detaches but equally delays
detaching a genuinely dead drive and shifts listing tail-latency
semantics, so it wants soak data before changing the default. The comment
records the invariant any such follow-up must keep -- consumer peek >=
producer stall, never stricter -- so it can never fail a drive before the
producer would. No behaviour change.

* test(e2e): cover codec-streaming parity under fault injection and NoSuchKey

The codec-streaming compat A/B previously ran only against a healthy
4-disk EC set with successful full GETs: the DiskFaultHarness was
constructed but never faulted, the error path was untested, and the
range assertion silently compared legacy-vs-legacy (ranges always fall
back to the duplex path), overstating what it proved.

Add two genuinely-failable scenarios reusing the existing harness and
fixtures:

- Parity reconstruction A/B: take one data disk offline and re-run the
  full object matrix on both phases while the EC 2+2 set rebuilds each
  large object from the surviving shards. Assert codec == legacy
  byte-for-byte (sha256) and header-for-header, and assert the codec
  phase served the reconstructed objects with zero duplex-pipe fallback
  (the reader gate is drive-health-independent, so the codec fast path
  is really exercised through reconstruction).
- NoSuchKey negative path: compare the HTTP status + S3 error code of a
  missing-key GET across the legacy and codec phases and require them to
  be identical (404/NoSuchKey), guarding against the codec env
  perturbing the error path.

Also clarify the range-phase comment so it is not misread as
codec-range correctness coverage: both sides are served by the same
legacy range path, so the assertion only proves ranges keep working and
keep falling back to legacy with the gates open.

Verified: cargo check/--no-run pass and the test passes locally
(1 passed; dup_codec=0 confirms the codec path ran).

The uring-integration leg ran on the runner's default TMPDIR, which may sit

dedicated ext4 loopback and point TMPDIR at it so the real io_uring dep

houseme 63b4568f85 fix(ecstore): reclaim orphan data dirs on the healthy heal path (#4781)
PR #4356 wired `reclaim_orphan_data_dirs` only into `heal_object`'s
post-heal tail, which runs after the `disks_to_heal_count == 0` early
return. That early return is exactly the state of the objects the sweep
targets: a valid `xl.meta` with all shards present plus a leaked
pre-#3510 data dir needs no shard healing, so a healthy heal returned
before reclaim and swept nothing. On a healthy deployment (single node,
no degraded disks) the reclaim was therefore dead code — an admin heal
walked the objects, "healed" them, and reclaimed no leaked space.

Run the best-effort reclaim on the `disks_to_heal_count == 0` path as
well, gated on `!opts.dry_run`. The shared match+log block is factored
into `reclaim_orphan_data_dirs_best_effort` so both exits behave
identically. A reclaim failure still never fails the heal.

Adds an end-to-end regression: put a healthy non-inline object, plant an
unreferenced UUID data dir under it on every disk that holds the object,
then drive `heal_object`. A dry-run heal must leave the stray in place; a
real heal must reclaim it while preserving the live data dirs, `xl.meta`,
and object contents. The test fails against the pre-fix control flow.

houseme 6886dca7d1 feat(ecstore): make GET codec-streaming a single rollout switch (backlog#1183) (#4752)
backlog#1183, staged rollout step. Simplify enabling the zero-duplex GET
codec-streaming fast path to a single switch — RUSTFS_GET_CODEC_STREAMING_ROLLOUT
(default "off") — now that body/header parity is proven (parity e2e net + bench
A/B on backlog#1183).

- Add a clean production rollout token "on" (aliases "full"/"production"); the
  legacy "internal"/"benchmark" tokens remain accepted.
- Flip DEFAULT_RUSTFS_GET_CODEC_STREAMING_ENABLE and the two ..._COMPAT_CONFIRMED
  defaults to true. They are retained as emergency kill-switches (set any to
  false to force the fast path off) but no longer gate enablement — the rollout
  switch does.

No production behavior change: with no env set the rollout switch defaults to
"off", so GET stays on the legacy duplex path exactly as before. Flipping the
hard default to on is deferred to a follow-up after a production soak.

Note (intentional semantics change): with the rollout switch opted in
("on"/"internal"/"benchmark"), codec streaming now activates without also
setting the two ..._COMPAT_CONFIRMED vars — compatibility is confirmed, so those
confirmations are baked in.

houseme 264b2dd480 perf(metrics): drop needless per-emission work on hot metric paths (#4743)
* perf(metrics): drop needless per-emission work on hot metric paths

Audit of the metrics hot paths surfaced four low-risk wins where emission did
work it did not need to:

- `record_file_cache_reclaim_success/error` (disk/local.rs) called `.to_string()`
  on `kind` (already `&'static str`) and on the `"ok"`/`"err"` literals, heap-
  allocating up to four `String`s per page-cache reclaim window — which runs per
  read-stream reclaim. The `metrics` macros accept `&'static str` label values
  directly, so pass them as-is.
- `record_read_repair_dedup` (set_disk/core/io_primitives.rs) likewise
  `.to_string()`-ed an already-`&'static str` `reason`.
- `SetDisks::get_object_reader` (set_disk/ops/object.rs) captured `Instant::now()`
  and emitted the `rustfs.lock.acquire.*` counter and histogram unconditionally
  on every GET, right beside an already-gated stage timer. Gate them behind
  `get_stage_metrics_enabled()` too, so an inactive observability config pays no
  per-GET clock read or recorder lookups.
- The per-response-body-chunk counter in server/http.rs re-ran the `counter!`
  registry lookup on every chunk (a streamed GET emits many). Resolve the
  label-less handle once into a `LazyLock<metrics::Counter>`; the global recorder
  is installed at startup before any response streams, so the cached handle binds
  to the final recorder.

No metric names or label values change. The only behavior change is that the
`rustfs.lock.acquire.*` GET-path metrics now follow the GET stage-metrics flag,
consistent with the neighbouring stage timings.

* perf(metrics): gate page-cache reclaim metrics behind metrics_enabled()

`record_file_cache_reclaim_success/error` run per read-stream reclaim window on
large-object reads and emitted unconditionally. When general metrics are
disabled the `counter!`/`histogram!` macros still construct three metric keys
per call for nothing. Skip the emission behind `rustfs_io_metrics::metrics_enabled()`,
matching how the io-metrics free functions self-gate. The serial reclaim-metrics
test now enables the flag (save/restore) alongside the existing stage gate.

Left ungated deliberately: `record_read_repair_dedup` (rare read-repair path,
and its non-serial test would need a global-flag toggle), and the HTTP body-chunk
counter (its cached handle already makes the disabled case a no-op increment).

houseme e742a540a4 test(cache): guard the body-cache eligibility gate against deny-list regressions (#1146) (#4742)
`full_object_plaintext_len` decides whether a body-cache hook hit may serve
bytes in place of the erasure read. It is a fail-closed allow-list: it excludes
every read whose `ReadPlan::build` applies some other transform (ranged/part,
raw/data-movement, restore, encrypted, remote) with an early `return None`,
then returns a `Some(..)` length only for the whole-plaintext cases. A newly
added `ReadPlan` branch that nobody teaches this gate about falls through to
`None` and safely bypasses the cache. Flip it to a deny-list and the same new
branch silently serves bytes in the wrong representation — the backlog#1108 /
#1109 / #1146 class of bug.

The existing unit and e2e tests only cover the branches that exist today. This
adds `scripts/check_body_cache_whitelist.sh`, a structural guard wired into
pre-commit / pre-pr / dev-check and CI, that asserts every exclusion predicate
and a `return None` still precede the first `Some(..)`. Reordering a predicate,
dropping one, moving the positive return ahead of the gate, or renaming/removing
the function all fail; wording, formatting, and adding a new exclusion in the
same gate do not. Mutation-tested against all four regression shapes.

This machine-enforces the structural invariant that backlog#1146 was kept open
to guard by hand.

houseme 6780140318 fix(object-data-cache): make the GET key write-unique and dedup the lookup (#4693)
fix(object-data-cache): make GET body cache key write-unique and dedup lookups

Address four object-data-cache GET-path findings (backlog#1107 batch):

ODC-06 (backlog#1111): the cache key was content-unique, not write-unique.
Extend ObjectDataCacheKey with the resolved version's modification time
(i128 unix nanoseconds, None -> 0), derived once in the shared planner so the
ecstore hook and the usecase layer produce an identical key. An unversioned
overwrite advances mod_time, so a stale node can no longer serve old bytes for
up to the TTL under an MD5 collision; etag + size stay as belt-and-braces.

ODC-16 (backlog#1121): every cacheable GET planned and looked up twice (once in
the ecstore hook, once in the usecase layer), double-counting hits, hit_bytes
and lookups. GetObjectReader now carries a GetObjectBodySource marker
(Unprobed / HookMissed / HookServed); the hook stamps it, and
build_get_object_body_with_cache serves a hook-served body directly and skips
its lookup whenever the hook already probed. One hook-served GET now records
exactly one lookup.

ODC-19 (backlog#1124): ENABLE=true with no explicit mode defaulted to HitOnly,
which never fills and keeps a permanent 0% hit rate. Default to
FillBufferedOnly, log the resolved mode at startup, and warn when HitOnly is
selected explicitly.

ODC-24 (backlog#1129): max_entry_bytes above the in-memory GET fill limits was
silently inert. Clamp the planner's size eligibility to
min(max_entry_bytes, seek-support threshold, 64 MiB buffer cap) so ineligible
sizes plan SkipTooLarge instead of being reported eligible, and warn at startup
when the excess is inert.

houseme c2362bca14 perf(ecstore): slice in-memory shards instead of copying them twice (#4687)
* perf(ecstore): slice in-memory shards instead of copying them twice (backlog#1159)

The GET path reads a shard out of the page cache into a `Bytes`, then
`open_disk_reader` erased it behind `Box<dyn AsyncRead>` by wrapping it in
a `Cursor`. Downstream, `BitrotReader` could only get it back by copying:
once out of the `Cursor` into its scratch buffer, and once from there into
the caller's buffer. CPU profiling of a cached 1 MiB GET (device reads = 0)
attributed 8.23% of the whole server to `Cursor::poll_read` alone — a copy
of data that was already sitting in memory.

Keep the source concrete instead of erasing it. `ShardReader` is an enum of
`InMemory(Cursor<Bytes>)` and `Stream(Box<dyn AsyncRead ...>)`, and the new
`ShardSource::try_take_block(n)` lets an in-memory source hand over the
`[hash][data]` block as a slice. `read_appending` uses it to verify the hash
on the slice and `extend_from_slice` the shard straight into the caller's
buffer: one copy instead of two.

`try_take_block` defaults to `None`, so a streaming source keeps the old
path byte for byte, along with its short-read and EOF semantics. A source
that cannot serve `n` bytes declines rather than truncating, so a partial
block still becomes UnexpectedEof rather than a short shard. The hash is
still checked before anything is appended, so a corrupt shard never reaches
the caller's buffer on either path. The deferred parity reader opens its
source lazily and stays on the streaming path; parity is only read when a
data shard fails.

Tests gate equivalence and non-vacuity:
  * `try_take_block` fires for `Cursor<Bytes>`, advances the position exactly
    as a read of the same length would, declines when fewer than `n` bytes
    remain, and returns `None` for a non-`Bytes` source — without this the
    equivalence test below would silently compare one path against itself;
  * both paths return identical bytes for the same shard;
  * a corrupt shard fails on the fast path too, appending nothing.

Verified: clippy --tests -D warnings clean; `erasure::` 215 passed, 0 failed;
`set_disk::core::io_primitives` 49 and `io_support::` 22 pass.

Stacked on #4681 (`read_appending`), which this builds on.

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(ecstore): implement ShardSource for Cursor<&[u8]> used by the erasure bench

`crates/ecstore/benches/erasure_benchmark.rs` builds
`BitrotReader<Cursor<&[u8]>>`, which the new `ShardSource` bound on
`ParallelReader`/`decode` does not accept. `cargo clippy --tests` does not
compile bench targets, so this only surfaced in CI's `--all-targets` run.

A borrowed slice carries no `Bytes` to hand out, so it takes the default
`try_take_block` and keeps the old streaming copy path — no behavior change.

Verified with the same target set CI uses:
`cargo clippy -p rustfs-ecstore --all-targets -- -D warnings` clean.

fix(ecstore): roll back delete on disks that staged then errored (backlog#1158)

#4300 rolls back a failed delete only on disks that returned Ok, skipping any
disk that staged its rollback backup, applied the delete, and then errored --
leaving that disk deleted while its peers are restored. On rollback, fan the
undo out to every online disk instead; the disk-side restore_delete_rollback
is already idempotent (Ok no-op when nothing was staged), so unstaged disks
are unaffected. The err.is_some() skip now applies only to the success/cleanup
path. Covers both single-object and batch delete.

houseme 8039a4ceae test(cache): end-to-end regressions for the body-cache hook P0s (#4675)
fix(ecstore): make body-cache hook re-registrable + add e2e regressions

ODC-21 (backlog#1126): the GET body-cache hook lived in a first-wins
OnceLock. When AppContext is rebuilt (config reload, test re-init) a fresh
ObjectDataCacheAdapter is constructed and re-registered, but the OnceLock
kept ecstore's GET probe pointed at adapter #1 while every usecase-layer
fill and invalidation targeted adapter #2 — silently degrading the feature
to a 0% hit rate with no error, log, or metric, and stranding entries in the
unreachable cache until their TTL.

Replace the slot with RwLock<Option<Arc<dyn GetObjectBodyCacheHook>>> so
re-registration atomically swaps to the newest adapter, and log at WARN when
a swap replaces a *different* instance (Arc::ptr_eq). RwLock over
ArcSwapOption because arc-swap's RefCnt is impl<T> (Sized, thin *mut T) and
cannot hold an Arc<dyn Trait> without a sized newtype wrapper; the probe
reads the slot once per full-object GET but only clones an Arc, negligible
next to the metadata quorum fan-out already done before the probe. Add a
test-only clear_get_object_body_cache_hook so tests register/unregister
deterministically.

With the hook now re-registrable, add true end-to-end regressions that drive
get_object_reader (not the full_object_plaintext_len predicate) against a
real erasure-coded, genuinely-compressed object via the blackbox
make_local_set_disks harness, with a stand-in hook playing the app-layer
cache (the injection point production uses; the adapter itself lives above
ecstore). These close the gap the predicate-only tests left — a caller that
opens a new shortcut serving the cached body directly, the original form of
both P0s:

- backlog#1108: a raw_data_movement_read must yield the STORED (compressed)
  bytes, never the cached plaintext.
- backlog#1109: a compressed cache hit must publish the DECOMPRESSED length
  as object_info.size (the UploadPartCopy invariant), with the streamed
  length matching.
- backlog#1146: a restore read (restore_request.days) must serve STORED
  bytes, not the cache.

Mutation-verified each e2e test bites: dropping the raw_data_movement_read
gate serves plaintext (fails #1108); removing the hit-site size republication
publishes 2972 vs 660000 (fails #1109); dropping the restore gate serves
plaintext (fails #1146).

houseme 8c76efead2 fix(cache): stop the GET body-cache hook from bypassing ReadPlan (#4654)
* fix(cache): gate GET body-cache hook to preserve ReadPlan output

The ecstore GET body-cache hook serves cached full-object plaintext
directly, bypassing ReadPlan/ReadTransform. That is only sound when the
normal read path returns that same plaintext byte-for-byte. Two probe
conditions were missing, plus two usecase-layer planner gaps.

ODC-01 (backlog#1108): raw/data-movement reads. ReadPlan::build returns
the STORED representation for raw_data_movement_read (e.g. compressed
bytes, length = oi.size), but the cache holds the post-decompression
body. Decommission (raw_data_movement_read: true) would receive
decompressed plaintext where raw compressed bytes are required, silently
corrupting the destination pool.

ODC-02 (backlog#1109): compressed objects. ReadTransform::Compressed
rewrites object_info.size to the decompressed length; on a hook hit
object_info is returned unchanged, so object_info.size is the compressed
size while the stream carries the decompressed body. UploadPartCopy then
uses src_info.size as the copy length and truncates the part.

Fix: gate the hook probe with should_probe_body_cache_hook, refusing
raw_data_movement_read, data_movement, and compressed objects, mirroring
the conditions get_small_object_direct_memory_decision already applies.

ODC-33 (backlog#1138): build_get_object_body_cache_plan lacked the
is_remote() exclusion the ecstore hook enforces; add it so transitioned
(remote-tier) objects are excluded uniformly.

ODC-C1 (backlog#1142): zero-length bodies save no I/O (ecstore returns an
empty body before the hook probe) yet the planner admitted them; change
the guard to response_content_length <= 0 so they plan Skip, mirroring
should_buffer_get_object_in_memory_with_threshold.

Tests: body_cache_hook_gate_tests (4) cover plain-probe plus
raw/data-movement/compressed skips; planner gains
plan_skips_remote_transitioned_objects and plan_skips_zero_length_objects.

Co-Authored-By: heihutu <heihutu@gmail.com>

* fix(cache): allow compressed bodies via a fail-closed read allow-list

The body-cache hook probe was gated by a deny-list that refused compressed
objects outright, which cost the cache every compressed body — a growing
share of stored data. Replace it with an allow-list that returns the exact
plaintext length a hit may serve, or None.

full_object_plaintext_len() answers a single question: would the normal
ReadPlan produce this object's complete plaintext, and under which size?
Compressed objects now qualify, and the hit site publishes the returned
length as object_info.size, reproducing the contract ReadTransform::
Compressed establishes. A hit whose body length disagrees is refused and
falls through to the erasure read.

This also closes a gate the deny-list only covered by accident: a restore
read forces ReadPlan down the Plain branch, so a compressed object yields
STORED bytes under its compressed size. Refusing compressed objects hid
that; admitting them exposes it, so restore reads are refused explicitly.

Being fail-closed, a newly added ReadPlan branch bypasses the cache by
default rather than silently serving the wrong representation — the
structural defect behind both backlog#1108 and backlog#1109.

houseme 399461c33e fix(ecstore): bound listing walks by drive stall, not total duration (#4647)
Foreground S3 listings wrapped the entire walk_dir stream in a single
wall-clock timeout (RUSTFS_DRIVE_WALKDIR_TIMEOUT_SECS, default 5s). That
budget measured how much data the walk had to produce rather than whether
the drive was still answering, so a healthy but large prefix on slow media
returned 500 InternalError / "Io error: timeout" to the client. The timer
also kept running while the walk was blocked writing to a slow consumer,
charging merge-side backpressure to the producer.

WalkDirOptions::stall_timeout_ms already carried the right semantics but was
only honored by the remote-disk RPC walk; LocalDisk::walk_dir ignored it
entirely. A single-drive deployment therefore had no way to distinguish a
hung drive from a big directory.

Teach LocalDisk::walk_dir to bound each individual drive read with the stall
budget, defaulting it from RUSTFS_DRIVE_WALKDIR_STALL_TIMEOUT_SECS when the
caller does not pin one, and let the foreground listing path skip the
wrapper-level total timeout. A walk that keeps making progress now runs to
completion; a drive that stops answering still fails with DiskError::Timeout.
Time spent blocked on the consumer stays outside the budget.

Heal and rebalance walks already skipped the total timeout and previously ran
unbounded on local drives. Give them an explicit, generous 60s stall budget so
this change does not tighten them from "no bound" to the 5s default.

houseme e3e5693e60 fix(ecstore): correct heal result drive-record reporting (#4555)
Two report-only defects on the heal result-reporting surface (they do not
affect the data path or heal decisions):

- default_heal_result (set_disk/ops/heal.rs): the offline-disk branch pushed
  an Offline record but fell through into the unconditional push, emitting a
  second (Corrupt) record for the same disk. This grew before/after.drives to
  disk_count + offline_count and misaligned every entry after the first offline
  slot. Add `continue` after the offline push, drive `disk_len` and the loop
  from a single `self.disks` snapshot, and assert `errs.len() == disk_len`.

- Sets::heal_format (core/sets.rs): the before/after drive lists were
  pre-filled with N default placeholders and then N real entries were pushed,
  yielding a 2N list whose healed status updates (indexed 0..N) landed on the
  blank placeholder half. Assign the lists directly from formats_to_drives_info
  (mirroring the set-level heal_format) so the healed updates hit the real
  entries.

Add regression tests covering offline/online record alignment and the
NoHealRequired and heal paths of the pool-level heal_format.

houseme c77c5f047a fix(ecstore): defer multipart part.N.meta cleanup until after commit (#4548)
complete_multipart_upload deleted every part.N.meta via
cleanup_multipart_path *before* the authoritative rename_data commit.
If rename_data then failed write quorum, the upload directory was left
with data files but no part metadata, so a retried CompleteMultipartUpload
could never read the parts again and the upload became permanently
uncompletable (client must abort and re-upload all parts).

Move cleanup_multipart_path to run only after rename_data returns Ok,
matching the existing "clean up only after commit" pattern already used
for the old data-dir GC and the upload-dir delete_all. On a failed commit
the staging part.N.meta now survive so the retry can complete.

Add a hermetic regression test that forces rename_data to fail on every
disk (destination bucket dir made read-only) and asserts the staging
part.N.meta are preserved for retry.

houseme f262fcfce0 perf(hotpath): add fine-grained PUT-path stage guards (HP-14) (#4541)
Close the ~10ms instrumentation residual on the PUT success path that the
existing coarse writer_setup/encode/rename stage metrics do not attribute.
Adds `hp_guard!` measurement scopes to the previously uninstrumented
sub-stages called out in backlog#935 item 2:

- SetDisks::acquire_read_lock / acquire_write_lock (namespace lock acquire)
- S3::put_object_prelookup (pre-write get_object_info lookup)
- MultiWriter::shutdown (bitrot writer flush/close)
- SetDisks::commit_rename_data_dir (old data-dir reclaim)
- S3Access::put_object (S3 authorization segment)

Instrumentation only: `hp_guard!` expands to nothing without the `hotpath`
feature, so this is a pure-observation change with zero behavior impact and
zero cost in default builds. The pre-lookup site wraps only the lookup call
in a scoped block so the guard measures that slice exactly while preserving
the existing match and control flow.

Verified: cargo check -p rustfs-ecstore (default and --features hotpath) and
cargo check -p rustfs (default and --features hotpath) all pass.

houseme 15808254d3 fix(ecstore): correct codec-streaming byte accounting and partNumber routing (#4535)
Two correctness defects on the opt-in codec-streaming GET path.

ECA-02 (#943): ErasureDecodeReader only decremented `remaining` for the
main fill buffer. Under the default DualInFlight policy each fill also
produces a queued stripe that is delivered to the client via
`prefetched_bufs.pop_front()` without touching `remaining`, so any object
larger than one erasure block finished with `remaining > 0` and the GET
terminated with LessData despite delivering all bytes. The inflated
`remaining` was also fed back into the fill worker, which used it to trim
the final stripe and to decide whether to read past EOF. Account for the
queued-stripe bytes when they enter the prefetch queue; queued buffers
come only from `Ok(true)` decodes so they are non-empty and bounded by
`remaining - main_buf.len()`, ruling out underflow.

ECA-04 (#945): the codec-streaming gate did not inspect `opts.part_number`.
A partNumber GET carries `range == None`, so it was not classified as a
Range request and reached the full-object codec-streaming reader, which
drops the storage offset/length returned by GetObjectReader::new. A
partNumber >= 2 request would then stream the whole object. Mirror the
direct-memory part_number fallback and route any partNumber request back
to the legacy duplex path, which applies the offset/length correctly.

Regression tests: DualInFlight read_to_end on a multi-block object and on
a non-block-aligned object; SingleInFlight vs DualInFlight byte-identical
output; gate fallback on partNumber requests.

Zhengchao An 3531abb34a feat(heal): disk-walk UNION enumeration to heal sub-quorum versions (backlog#920) (#4527)
B5 switched heal enumeration to list_object_versions, which only reflects the
read-quorum metadata view: a version present on fewer than read-quorum disks was
never enumerated, so it was never healed. Add a per-erasure-set disk-walk UNION
enumerator (mirrors MinIO global-heal.go objQuorum=1 listPathRaw +
mergeXLV2Versions) that surfaces every (object, version) present on ANY disk and
feeds each to the existing per-version heal_object.

- filemeta: MetaCacheEntries::resolve_union (dir_quorum=1/obj_quorum=1) yields the
  cross-disk version union at one tested seam.
- ecstore: SetDisks::heal_walk_versions_page (list_path_raw fan-out, min_disks=1,

houseme 7048a9a3ed test(ecstore): run shard_read_costs empty test under a Tokio runtime (#4496)
shard_read_costs_for_empty_disk_set_are_empty was a plain sync #[test], but
shard_read_costs_for_disks consults process-global topology state
(local_endpoint_hosts_for_shard_costs) whose fast-lock manager lazily spawns a
background cleanup task on first access. When this test was the first in a
process to touch that global — as under nextest's per-test isolation — the
tokio::spawn panicked with a TryCurrentError because no runtime was present,
making the test order-dependent flaky in CI (it passes only when some sibling
tokio test initializes the manager first).

Run it under a Tokio runtime like the sibling reservation tests
(#[tokio::test]), so the lazy init's spawn always has a runtime. Test-only
change; no production behavior change.

Verified failing before the change and passing after under both
`cargo test` and `cargo nextest run` in isolation.

Zhengchao An fefa70b31e fix(ecstore): stop ListMultipartUploads from returning one upload past max-uploads (#4447)
fix(ecstore): stop ListMultipartUploads from returning one upload past max-uploads (backlog#954)

The result-collection loop in `SetDisks::list_multipart_uploads` pushed an
upload into the page and only then checked `ret_uploads.len() > max_uploads`,
so each page returned up to max_uploads + 1 uploads and pointed
`next_upload_id_marker` at that surplus entry, violating the S3
ListMultipartUploads max-uploads contract.

Move the cap check before the push (MinIO-style) so a page never exceeds
max_uploads, and derive `is_truncated` from the post-marker cursor position
(`upload_idx < uploads.len()`) rather than comparing the page length against
the full listing length. The old length comparison mis-reported truncation on
the final page whenever a marker had skipped earlier entries, which prevented
marker-based pagination from terminating.

Add a regression test that starts more in-progress uploads than a page holds
and asserts a single page returns exactly max_uploads with a correct
next-marker, that the exact-boundary case is not marked truncated, and that
paginating one upload at a time enumerates every upload once with no loss,
duplication, or non-termination.

Incidental: add the missing `ctx` field to the `new_multipart_lock_test_store`
cfg(test) helper so the ecstore test build compiles after the #4413/#4437
merge collision.

Zhengchao An df9cbc4ed1 fix(ecstore): validate erasure distribution values to avoid shuffle index panic (#4427)
fix(ecstore): validate erasure distribution values to avoid shuffle index panic (backlog#949)

The element values of `erasure.distribution` read from `xl.meta` were never
range-checked. `FileInfo::is_valid()` and `MetaObjectV1::valid()` only verified
`distribution.len()` and the `erasure.index` bound, not that each distribution
value is a valid 1-based slot in `[1, N]`. The metadata shuffle helpers then use
these values directly as `distribution[k] - 1` indices, so a corrupt or
adversarial `xl.meta` carrying a `0` (usize underflow) or a value greater than N
(out-of-bounds) triggers a panic in the shuffle path, turning bad-disk metadata
that erasure coding is meant to tolerate into a request/task crash.

Fix, two layers:
- Validate distribution values at metadata acceptance: `is_valid_distribution`
  now requires the distribution to be a permutation of `1..=N` (correct length,
  every value in range, no duplicates). `FileInfo::is_valid()` and
  `MetaObjectV1::valid()` use it, so `find_file_info_in_quorum` rejects corrupt
  metadata and it surfaces as a clean `ErasureReadQuorum` error instead of an
  index path.
- Defensive indexing in the shuffle helpers (`shuffle_disks_and_parts_metadata`,
  `_by_index`, `_by_index_owned`, `shuffle_parts_metadata`, `shuffle_disks`,
  `shuffle_check_parts`): out-of-range distribution values are skipped via
  `checked_sub(1)` + bounds-checked slot access instead of a bare `idx - 1`
  index, matching the existing pattern in
  `collect_inline_data_shard_fileinfos_by_index`.

Regression tests: `is_valid_distribution`/`is_valid`/`valid` reject distributions
containing `0`, values greater than N, duplicates, and wrong length while
accepting valid permutations; the shuffle helpers no longer panic on corrupt
distributions and preserve output length.

Zhengchao An 91dec123d9 refactor(ecstore): add per-instance InstanceContext, migrate erasure setup type (#4413)
* refactor(ecstore): add per-instance InstanceContext, migrate erasure setup type

Phase 5 of the global-singleton consolidation (backlog#939): begin moving
runtime identity state out of process globals so multiple ECStore instances
can coexist in one process. Isolation is carried by the object graph
(ECStore -> Sets -> SetDisks holding an Arc<InstanceContext>), not a
task-local, which does not propagate across the many internal tokio::spawn
boundaries in the data/background paths.

This first slice migrates the erasure setup type -- previously three
independent process-global bools -- into a single per-instance
RwLock<SetupType> that derives is_erasure / is_dist_erasure / is_erasure_sd,
removing a triple source of truth that could drift out of sync.

- New runtime::instance module: InstanceContext + process bootstrap context.
- The legacy free-function facade (is_erasure/update_erasure_type/...) keeps
  its signatures and forwards to the current instance's context, falling back
  to the bootstrap context before a store is published.
- ECStore gains a pub(crate) ctx field and setup_is_* accessors; its
  constructors adopt the bootstrap context (never mint a fresh one) so startup
  writes and post-construction reads share one cell -- single-instance
  behavior is byte-for-byte unchanged.

Tests: erasure predicate derivation vs the legacy behavior, object-graph
carrier isolation across two ECStore instances, and bootstrap adoption.

* refactor(ecstore): source the namespace lock manager per-instance (#4417)

refactor(ecstore): source the namespace lock manager per-instance (Phase 5 Slice 3)

Phase 5 Slice 3 (backlog#939): give each instance its own lock namespace by
sourcing SetDisks' lock manager from the instance context instead of the
process singleton. This removes the false cross-instance mutual exclusion (and
attendant ABBA risk) that a shared GlobalLockManager would cause once multiple
instances coexist.

- InstanceContext gains a `lock_manager: Arc<GlobalLockManager>`. `new()` mints
  a fresh manager (independent per-instance); `bootstrap_ctx()` aliases the
  process singleton via get_global_lock_manager(), so a single-instance
  deployment keeps exactly one shared namespace.
- SetDisks::new sources `local_lock_manager` from `ctx.lock_manager()` (the ctx
  it already adopts), not `runtime_sources::global_lock_manager()`. Single
  instance: same Arc as before, so behavior is unchanged.
- Remove the now-unused `runtime_sources::global_lock_manager()` wrapper.

Tests: bootstrap lock manager aliases the process singleton; two fresh contexts
own distinct managers; a SetDisks' lock manager is the one from its context and
aliases the global singleton in a single-instance build.

Verification: cargo test -p rustfs-ecstore (10 Phase 5 + set_disk locking
regressions green), cargo clippy -p rustfs-ecstore --all-targets (clean),
make pre-commit (pass).

Zhengchao An 1e6207c08e fix(lock): fence write commit on lock loss (#4406)
fix(lock): fence write commit on lock loss (backlog#899 Phase 2)

Phase 0+1 (#4388) made object write locks refreshable and marks the guard
lost when the heartbeat can no longer refresh a quorum, but does not act on
it. Under a partition a long write's lock can expire on an unreachable node
and be reclaimed, letting a third party re-acquire it; the original writer
keeps going and both commit -- a double write.

Expose the loss signal through NamespaceLockGuard::is_lock_lost() and
ObjectLockDiagGuard::is_lock_lost(), and fence the commit in put_object and
complete_multipart_upload: immediately before rename_data (the atomic commit
point), abort with a retryable NamespaceLockQuorumUnavailable (503) if the
lock was lost. In multipart the check precedes cleanup_multipart_path so a
lost lock leaves the upload intact and retryable. A write that already
reached rename_data Ok is durable and never aborted.

The loss criterion is unchanged (reacts to Phase 1's signal). Heal and the
long-GET read side are deferred follow-ups.

Zhengchao An afc7f1d6f9 fix(ecstore): make post-commit old data dir cleanup best-effort (#4386)
* fix(ecstore): make post-commit old data dir cleanup best-effort (backlog#898)

A write is authoritatively committed once rename_data returns Ok (the new
version is durable on >= write_quorum disks and immediately readable). The
subsequent reclamation of the now-dereferenced old object/<data_dir> is pure
space reclamation, yet commit_rename_data_dir propagated a below-quorum GC
failure via `?` into ErasureWriteQuorum -> 503, producing a false-negative
ACK for an already-persisted write. This is a deliberate divergence from
MinIO (erasure-object.go:1577), which couples the two; the divergence is
justified by durability semantics, not parity.

Changes:
- commit_rename_data_dir now returns a structured OldDataDirCleanup receipt
  and never returns Err. Adds an old==committed-dir anti-misdelete guard and
  a committed_data_dir parameter. Classification is extracted into pure
  functions (classify_old_data_dir_cleanup / map_cleanup_join_result /
  is_cleanup_not_found) so it is unit-testable. Task panic/cancel is mapped to
  a non-ignored DiskError::other (never DiskNotFound), and not-found is
  normalized to reclaimed.
- object.rs / multipart.rs consume the receipt instead of `?`. The result
  reverts to Ok, so the invalidate_get_object_metadata_cache self-heal and the
  capacity/compression accounting that a `?` early-return previously skipped
  now run on the cleanup-failure path too.
- On residue, report_old_data_dir_cleanup emits leak metrics and enqueues an
  object heal over the existing heal channel (disk-health signal replacing the
  503). heal_object -> reclaim_orphan_data_dirs already reclaims unreferenced
  local data dirs, closing the loop end to end.
- Adds rustfs_old_data_dir_* counters (attempted/reclaimed/leaked/below_quorum)
  as the operator-visible backstop for leaked residue.
- Adds a test-only (#[cfg(test)]) delete fault-injection seam; in production it
  inlines to a no-op None and has no behavioral effect.

Tests: pure-function A/C group + join-error mapping + actions decision; A5/A5b
real-disk guard/reclaim integration; end-to-end overwrite returning 200 while
old-data-dir cleanup fails. #864 rollback guard test remains green.

houseme 3f13d098b4 feat(observability): feature-gated hotpath instrumentation for the data path (#4394)
Merge the hotpath-rs wall-time instrumentation from the backlog#936 analysis worktree behind an opt-in 'hotpath' cargo feature, keeping the default build at zero overhead and zero dependency.

- hotpath is an optional dependency everywhere (dep:hotpath feature syntax); the default dependency tree contains no hotpath crate at all
- 40+ measurement points across S3 handlers, ECStore/SetDisks object and multipart ops, erasure encode/decode, bitrot, LocalDisk I/O, FileMeta codec, and HashReader
- attribute sites use #[cfg_attr(feature = "hotpath", hotpath::measure)]; async_trait bodies use per-crate hp_guard! macros (ecstore + rustfs bin); rio gates measure_block! behind hp_measure_block!
- feature chain: rustfs -> rustfs-ecstore -> rustfs-rio / rustfs-filemeta, each crate owning its own gate
- hotpath-alloc is intentionally not wired up (hotpath 0.21.x TLS panic on cross-thread guard drop under tokio, see backlog#935); mimalloc stays the unconditional global allocator
- docs/development/hotpath-profiling.md documents building, HOTPATH_* env vars, SIGTERM report flow, and how to reproduce the backlog#936 timing reports

houseme bd5d3c5d92 perf(ecstore): data-shards-only lockstep GET reads with stripe-aligned deferred parity engagement (opt-in) (#4392)
* feat(ecstore): add stripe-advance handles for deferred bitrot readers

Give DeferredObjectReader a shared pending state and expose a
DeferredReaderStripeHandle that advances the still-unopened source by whole
bitrot blocks using the same bitrot_encoded_range geometry the reader was
created with (identity mapping when hash_size == 0). This lets the GET decode
path open a parity shard aligned to the stripe where a data shard failed
instead of reading every parity shard on every stripe (backlog#923).

An already-opened (or failed) reader rejects the advance so callers retire it
rather than engage it out of alignment; bitrot verification after an advance
checks the advanced stripe's block against that stripe's stored hash.

* perf(ecstore): read only data shards on healthy lockstep GET behind opt-in gate

PR #4289's lockstep fix made every reconstruction-verifying GET read all
data+parity shards per stripe; the parity blocks are read, bitrot-hashed and
then discarded, a deterministic 2x read-bytes/IOPS/hash-CPU amplification on
healthy 2+2 objects (backlog#923). With the new opt-in gate
RUSTFS_GET_LOCKSTEP_DATA_SHARDS_ONLY_ENABLE=true (default: false, behavior
identical to main):

- read_lockstep keeps only the data slots engaged while the object is
  healthy; parity slots stay unopened deferred readers.
- When a data shard is missing or dies at stripe k, parity readers are
  engaged mid-object by advancing their deferred stripe handle to stripe k,
  preserving the lockstep alignment invariant from backlog#832.
- Degraded stripes engage one parity beyond the decode quorum so
  reconstruction verification keeps an extra source to check against
  (erasure.rs only verifies when available > data shards); an engaged parity
  reader that errors is retired for the rest of the object like any other,
  and a parity reader that cannot be realigned is retired instead of being
  read out of position.
- fill_deferred_bitrot_readers records stripe handles for deferred slots and,
  gate-on only, swaps eagerly opened parity readers for unopened deferred
  ones so they remain engageable mid-object; ready/error bookkeeping used by
  quorum decisions is untouched.
- Both GET paths (legacy duplex via Erasure::decode_with_stripe_handles,
  codec streaming via ParallelReader::with_deferred_parity_handles) carry the
  handles from reader setup.

Short-read -> UnexpectedEof -> whole-object retirement and the
inconsistent-source rejection are unchanged in both gate modes; tests lock
the healthy-path data-shards-only call counts, the default read-all-shards
behavior, mid-object parity engagement for streaming and hash_size==0
formats, and mid-stream inconsistent-parity rejection.

houseme e7cc719c17 perf(ecstore): move speculative PUT-tail tmp cleanup off the hot path (#4389)
* perf(ecstore): move speculative tmp cleanup off the PUT hot path

On a successful PUT, rename_data has already moved the data dir out of the tmp workspace, so the delete_all(RUSTFS_META_TMP_BUCKET) at the end of SetDisks::put_object is a speculative no-op safety net. It was awaited inline on the response path, where profiling (backlog#924 / HP-3) showed the same-disk queueing behind fsync-heavy load turns a ~49us no-op into ~9ms average (p99 77ms, macOS F_FULLFSYNC amplified) added to every PUT.

Run that cleanup on a spawned task instead, keeping it as a real backstop (rename_data's remove_std only removes empty dirs and silently ignores failures). The failure path (quorum loss / rollback) keeps the cleanup inline so a failed PUT never returns with tmp shards still on disk. If the process dies before the spawned task runs, cleanup_stale_tmp_objects (24h expiry, 5-minute loop) reclaims the entry.

Scope note: ops/multipart.rs delete_all on RUSTFS_META_MULTIPART_BUCKET is intentionally untouched; it removes real leftovers and deferring it would widen CompleteMultipartUpload/Abort races.

Regression tests (hermetic SetDisks on formatted local disks, no global state): PUT success drains the tmp workspace (polling the spawned task), and PUT failure (missing bucket volume, rename_data quorum error after tmp shards were written) cleans the workspace inline before returning.

* fix(ecstore): do not retry NotFound in reliable_rename_inner

reliable_rename_inner blindly retried the rename once on any error. A NotFound retry cannot succeed: nothing recreates the missing source or parent directory between attempts, so the second rename fails identically and speculative cleanup renames (e.g. move_to_trash on an already-removed tmp path) always paid for two syscalls.

Extract the retry decision into should_retry_rename: NotFound returns immediately, any other error keeps the existing single retry. This helper is shared by the rename_data commit path via rename_all, so behavior there is covered by a new rename_all success regression test alongside the retry-predicate tests.

Zhengchao An 7efacbdf95 fix(filemeta): validate part array lengths in into_fileinfo (#4382)
MetaObject::into_fileinfo indexed part_sizes[i]/part_actual_sizes[i] by
part_numbers.len() without checking the arrays are the same length,
unlike the adjacent part_etags/part_indices which are length-guarded.
decode_from pushes the three arrays independently and the xl.meta CRC
only covers bytes, so a CRC-valid but internally inconsistent xl.meta
(foreign writer / MinIO interop) triggers an out-of-bounds panic on the
GET/HEAD/LIST decode path.

Guard the three arrays for equal length and return Err(FileCorrupt) so a
divergent shard is skipped and quorum uses the other disks, instead of
panicking the request task. Cascade into_fileinfo to Result across its
callers, and fix io_primitives early-return to derive the version id from
the merged header and fall into the per-disk loop (single-disk survival +
heal). The 2118 merge-first path is left as a documented follow-up.

* perf(ecstore): replace linear merge scan with k-way heap and drop clone-to-parse (backlog#874 backlog#875)

merge_entry_channels advanced the k-way merge with a linear scan over all
channel heads (O(entries x channels)) and allocated two fresh Strings per
pairwise comparison via path::clean. Every step also cloned MetaCacheEntry
values, including entry.clone().xl_meta() clone-to-parse calls.

- Introduce MergeHead with a cached cleaned name (allocated only when the
  raw name is not already clean) and drive the merge with a BinaryHeap of
  boxed heads: O(log channels) per entry, allocation-free comparisons.
- Move entries through the merge instead of cloning; the winner is sent
  without an intermediate copy.
- Remove the dead merge_file_meta_versions block: it only ran for
  prefix-dir groups whose entries have empty metadata, so xl_meta() always
  failed; cross-drive version merging happens in the resolve path.
- Keep legacy same-name semantics (dir groups collapse, objects shadow
  prefix dirs, later object candidate wins) and add regression tests for
  interleaved ordering, dir/object precedence, uncleaned-name grouping,
  and prefix-dir collapse.

* fix(ecstore): honor ascending versions_sort in ListObjects walk (#4348)

* fix(ecstore): honor ascending versions_sort in walk and document ordering invariant (backlog#876)

The walk loop carried a bare `//TODO: SORT` inside the
`WalkVersionsSortOrder::Ascending` branch, so the requested ascending
order was silently ignored and versions streamed newest-first (the raw
FileMeta order). WalkOptions defaults to Ascending, so every default
walker -- notably replication resync, which replays versions and needs
oldest-first to preserve the version-stack order -- received the exact
opposite of the contract.

FileMeta maintains versions newest-first (sort_by_mod_time is
descending) and into_file_info_versions preserves that order, so
ascending emission is the exact reverse of file_info_versions output.
Reverse in place when ascending is requested and add a regression test
locking the newest-first invariant plus the reversal contract.

Key-ordering audit result (no gap found): per-disk walkers emit sorted
streams, merge_entry_channels performs an ordered k-way merge, and
gather_results only filters by marker/limit, so ListObjects key order is
guaranteed upstream and needs no post-sort.

* perf(ecstore): enable GET metadata early-stop by default (#4349)

* perf(ecstore): enable GET metadata early-stop by default with env opt-out (backlog#872)

The metadata early-stop fanout (read_all_fileinfo_early_stop) has been
implemented and instrumented for a while but stayed behind an opt-in
flag, so default GETs always waited for every disk to answer the
metadata read even after quorum agreement was reached.

Flip RUSTFS_GET_METADATA_EARLY_STOP_ENABLE to default-on. The gate stays
conservative: should_allow_metadata_early_stop only admits metadata-only
reads (read_data=false) without version_id, healing, or free-version
requirements, everything else falls back to the full-wait fanout, and
setting the env var to false restores the old behavior entirely. The
version-aware gate (RUSTFS_GET_METADATA_VERSION_EARLY_STOP_ENABLE)
remains opt-in because versioned reads carry a higher stale-selection
risk profile.

Also replace the stale "optimize concurrency" TODO in
get_object_fileinfo with a pointer to the early-stop implementation and
add regression tests for the new default plus the explicit opt-out path.

* perf(ecstore): lazily construct codec streaming multipart readers (#4350)

* perf(ecstore): lazily construct codec streaming multipart part readers (backlog#871)

get_object_decode_reader_with_fileinfo opened shard readers for every
part of a multipart object before returning the streaming reader, so
TTFB paid for parts x disks file opens up front and an early client
disconnect wasted the setup work for every unread part.

Replace the eager loop with LazyMultipartCodecStreamingReader: the first
part is still built eagerly so the dominant fallback conditions (missing
shards / read quorum) are detected before any byte is streamed and the
whole request can fall back to the legacy duplex path exactly as before.
Each subsequent part is built on demand -- when the previous part hits
EOF -- via a spawned task handle owned by the reader; dropping the
reader aborts an in-flight build so disconnects stop all further IO.

If a later part hits a fallback condition mid-stream (a shard vanished
after the request started), the reader surfaces an explicit read error
with a pipeline-failure metric instead of silently degrading; the
client's retry then detects the condition on the eager first-part setup
and takes the legacy path cleanly.

Adds unit tests for in-order streaming across lazy boundaries, deferred
construction (no build when the client stops within part 1), and the
mid-stream fallback error path.

* perf(ecstore): prefetch next multipart part reader setup during decode (#4351)

* perf(ecstore): prefetch next multipart part reader setup during decode (backlog#870)

get_object_with_fileinfo processed multipart parts strictly serially:
the next part's bitrot reader setup (file opens + read-quorum wait
across all disks) only started after the current part finished
decoding, so large multipart reads paid full setup latency between
every part.

Overlap the two stages with a depth-one pipeline: right after the
current part's readers are obtained, the next part's setup is spawned
(shared inputs behind Arc) and joined when the loop reaches that part.
The shared setup_multipart_part_readers helper keeps stage-duration
metrics semantics identical for both paths; a failed or stale prefetch
falls back to the synchronous setup, and the PrefetchedReaderSetup
guard aborts the in-flight task on error returns, early breaks, or
caller drop so disconnects stop background disk IO.

Gate: RUSTFS_GET_MULTIPART_READER_SETUP_PREFETCH (default on, env
opt-out). Adds a three-part end-to-end read test covering the prefetch
hit path and cross-part content ordering.

shuffle_disks_and_parts_metadata_by_index deep-cloned every valid
FileInfo (parts, erasure info, metadata map) once per disk on each GET.
Add an ownership-taking variant that runs the same by-index consistency
check as a read-only first pass and then moves entries into their

handles are Arc clones and stay cheap.

- get_object_fileinfo's disks.clone() stays: DiskStore is Arc<Disk>, so
  the clone is per-slot refcounting and correctly avoids holding the
  RwLock read guard across the metadata fanout awaits.
- get_object_decode_reader_with_fileinfo keeps the borrowing shuffle:
  its caller must retain files/disks for the legacy fallback path, so an
  owned variant would just shift the same clone upstream.
- The metadata-cache hit path still clones parts_metadata; sharing the
  cached entry via Arc changes the read-path return types and is left
  as a follow-up.

Equivalence tests cover both the by-index placement and the mod-time
fallback against the borrowing variant.

* fix(ecstore): gate merge emission on cleaned key and clear clippy redundant_clone

Address review + CI findings on the ListObjects/GET optimization PR:

- merge_entry_channels gated emission on the raw entry name while the heap
  orders by the cleaned key, so entries whose cleaned order and raw byte order
  disagree (e.g. redundant slashes) could be dropped. Gate on the same cleaned
  sort key the heap uses; add a regression test (`a//c` after `a/b`).
- Drop three redundant `.clone()` calls in test code flagged by
  clippy::redundant_clone (owned-shuffle equivalence tests and the walk
  ascending-versions contract test) that failed the CI clippy gate.
- Document the known mid-stream fallback limitation of the opt-in multipart
  codec streaming reader (default off) and mark the in-place per-part legacy
  degradation as a follow-up.

* fix(ecstore): force full metadata fanout for object tagging writes (backlog#872)

put_object_tags reads the object fileinfo with read_data=false and then
writes the updated tags to the online-disk set that read returned. With
metadata early-stop enabled by default, that read now returns as soon as
read quorum is reached, so the online-disk set is only a read-quorum
subset. Writing tags to that subset fails write quorum -> ErasureWriteQuorum
-> S3 SlowDown, which is exactly the s3-tests tagging failures
(PutObjectTagging/DeleteObjectTagging, reached max retries).

Thread a caller-controlled `allow_early_stop` gate through
read_all_fileinfo_observed/_inner and add get_object_fileinfo_gated;
put_object_tags calls it with allow_early_stop=false so the metadata read
does the full quorum fanout and returns the complete online-disk set as
the write target. Pure-read callers (GET/HEAD/tag read) keep the
early-stop fast path unchanged.

Extract metadata_early_stop_permitted() as the single gate and add a unit
test locking the invariant: caller opt-out (and observe=false, and data
reads) never early-stop even with the env flags on.

houseme c9b976ad46 feat(ecstore): reclaim orphaned data dirs during heal (#4356)
* feat(ecstore): reclaim orphaned data dirs during heal (backlog #3231/#3191)

Pre-#3510, an unversioned overwrite leaked one UUID-named data dir per PUT.
The write path now cleans up going forward, but pre-existing strays stay on
disk forever: heal's dangling logic only removes whole objects whose data is
missing, never surplus data dirs of an otherwise-healthy object. That leaked
space is what eventually made ListObjects scan tens of GB and time out.

Add SetDisks::reclaim_orphan_data_dirs, a fail-closed, quorum-safe sweep that
mirrors purge_orphan_dir_object:

- referenced set is the UNION of get_data_dirs() across every online replica's
  xl.meta, so a dir named by any replica is kept;
- if a disk holds the object dir but its xl.meta is missing or unparseable the
  object is treated as degraded and nothing is removed;
- only UUID-named subdirectories are ever considered.

Wire it into heal_object's healthy tail (under the object write lock) as a
best-effort step so the background heal scanner and admin heal recover the
leaked space automatically; a reclaim failure never fails the heal.

Covered by four unit tests: removal of an unreferenced dir, no-op when all dirs
are referenced, fail-closed abort on missing metadata, and cross-replica union
preservation.

Zhengchao An 5594b18912 fix(ecstore): make delete_volume non-recursive by default to prevent bucket-heal wipe (backlog#799 B1) (#4339)
* fix(ecstore): make delete_volume non-recursive by default to prevent bucket-heal wipe (backlog#799 B1)

`delete_volume` unconditionally `remove_dir_all`'d the whole bucket tree, and the
bucket-heal "remove" branch called it fire-and-forget on every local disk. A
mis-classified "dangling" bucket (or a non-force S3 DeleteBucket on a populated
bucket) was therefore recursively wiped — a potential whole-bucket data loss.
The `VolumeNotEmpty` -> recreate/`BucketNotEmpty` handling already present in
both delete_bucket paths was dead code because the primitive never refused.

Add an explicit `force_delete` flag to `DiskAPI::delete_volume` and default the
non-force path to a non-recursive `remove_dir` (rmdir), which fails atomically
with `VolumeNotEmpty` if the bucket still holds any object data. Only an explicit
force delete (S3 force bucket delete) removes recursively. Mirrors MinIO's
`xlStorage.DeleteVol` (`Remove` vs `RemoveAll`).

- Trait + all impls (local behavior, dispatch, disk_store, remote RPC) take the
  flag; the gRPC `DeleteVolumeRequest` gains a `force` field (proto3 default
  false → old peers get the safe non-recursive behavior on rolling upgrade).
- Heal remove branch passes `false` and no longer discards the result: a
  `VolumeNotEmpty` refusal is logged (the bucket is not dangling) instead of
  wiping data.
- Both `delete_bucket` paths pass `opts.force`, activating the previously-dead
  `VolumeNotEmpty` -> `BucketNotEmpty`/recreate handling (correct S3 semantics).

Adds a regression test: non-force delete of a non-empty bucket returns
VolumeNotEmpty and preserves the data; force delete removes it.

Design converged by two independent expert reviews (MinIO-fidelity +
defense-in-depth) referencing MinIO xl-storage.go. Refs backlog#799 (B1),
issue rustfs/backlog#850. The safety expert's deeper hardening (typed
capability instead of a bool, trash-instead-of-in-place for force, quorum
re-verification of dangling) is noted on #850 as follow-up.

* fix(ecstore): reword 'mis-classified' -> 'misclassified' to satisfy typos (backlog#799 B1)

* fix(rustfs): thread force_delete through StorageDiskRpcExt::delete_volume + test literal (backlog#799 B1)
