fix(ecstore): improve expect() messages in replication_resyncer
Replace unwrap() with expect() for better error diagnostics in
replication_resyncer.rs:
- HashMap get_mut calls now have descriptive expect messages
- format() calls now use unwrap_or_else for error handling
Refs https://github.com/rustfs/backlog/issues/729
fix(ecstore): replace k.unwrap() with safe pattern in bucket_target_sys
Replace unsafe k.unwrap().as_str() with if let Some(key_str) pattern
in 5 locations where HeaderMap iterator yields (Option<HeaderName>, Value).
This prevents potential panics if header names are invalid.

* fix(io-core): avoid blocking on pooled buffer return
* perf(put): add slow inflight diagnostics
* perf(put): fix 16KiB regression with threshold and pool bypass
- Lower SMALL_EAGER_PUT_MAX_SIZE from 256KB to 8KB so objects >8KiB
use the streaming BufReader path (matches baseline behavior)
- Add POOL_BYPASE_MAX_SIZE (16KiB) to bypass BytesPool for very small
objects, avoiding Small-tier Mutex contention under high concurrency
- Add read_small_put_body_exact_direct() for direct Vec<u8> allocation
- Fix stale test assertions to match new 8KB threshold
Root cause analysis: the 16KiB regression was primarily caused by
instrumentation overhead in set_disk.rs (4x Instant::now() + metrics
per PUT), not BytesPool contention. Lowering the threshold eliminates
the eager-path overhead for 16KiB+ objects.
* perf(put): gate stage metrics behind observability flag
Add put_stage_metrics_enabled() AtomicBool switch in io-metrics crate.
When disabled (default), record_put_object_path() and
record_put_object_stage_duration() are no-ops, avoiding unnecessary
histogram/counter macro overhead in the PUT hot path.
The flag is set to true during startup when OTEL metric export is
enabled (rustfs_obs::observability_metric_enabled() == true).
This eliminates the per-request metrics overhead that contributed
to the 16KiB PUT regression when metrics collection is not active.
* perf(put): comprehensive optimization - restore eager path, cache env, remove UUID
Change 1: Restore SMALL_EAGER_PUT_MAX_SIZE from 8KB to 1MB
- The try_lock() fix (d13a189e3) eliminates the blocking that caused
service health timeouts under 512KiB c64 load
- Eager path with BytesPool is now safe for objects up to 1MB
- Recovers the eager path benefit for 32KiB-256KiB objects
Change 2: Adjust POOL_BYPASE_MAX_SIZE from 16KB to 4KB
- With eager path restored to 1MB, objects 4KB-1MB benefit from pool reuse
- Only ≤4KB objects bypass the pool (allocation cost negligible)
Change 3: Cache RUSTFS_ERASURE_ENCODE_MAX_INFLIGHT_BYTES via OnceLock
- Eliminates per-encode std::env::var() syscall
- Env var still works (read once at first use)
Change 4: Replace Uuid::new_v4() with Uuid::nil() in Erasure construction
- _id field is unused in hot paths (documented in code)
- Eliminates CSPRNG syscall per PUT request
Change 5: Add concurrency-aware buffer sizing to PUT path
- Reuses get_concurrency_aware_buffer_size() from GET path
- Reduces buffer size under high concurrency (0.4x at >8 concurrent)
- Lowers memory pressure for >1MB streaming PUTs
* chore: add pyroscope feature flag and clean up imports
- Add pyroscope feature flag forwarding to rustfs-obs
- Remove unused allow(non_upper_case_globals) in globals.rs
- Sort imports and fix Cargo.toml formatting consistency
* style: fix import ordering and code formatting
- Sort imports alphabetically in globals.rs, encode.rs
- Fix indentation in erasure_coding encode/erasure
- Clean up HashReader formatting in object_usecase.rs
* fix(test): use tokio::test for request_logging_layer tests
The tests call tokio::spawn via RequestContextLayer, which requires a
Tokio runtime. Changed from #[test] + futures::executor::block_on to
#[tokio::test] + .await, and replaced tracing::subscriber::with_default
with tracing::subscriber::set_default to support async.
* fix(bench): normalize no-space throughput/latency parsing in to_bps/to_ms
When a benchmark tool prints throughput without a separator (e.g. 123MiB/s),
awk '{print $2}' returns empty because the whole string is one field,
causing to_bps to return N/A and losing valid measurements in CSV output.
Insert a space between number and unit via sed before awk field splitting.
Same fix applied to to_ms for latency values like '50ms'.
Also add TODO comment on PUT path noting that get_concurrency_aware_buffer_size
reads ACTIVE_GET_REQUESTS instead of PUT concurrency (PR #3514 review).
Refs: PR #3514 review comments by chatgpt-codex-connector
* fix(metrics): correct POOL_BYPASS comments and separate PUT vs generic stage metrics
- Fix 3 comment-code mismatches: POOL_BYPASS_MAX_SIZE is 4KiB, not 16KiB
- Add generic record_stage_duration() with separate histogram
(rustfs_internal_stage_duration_ms) for non-PUT paths
- Replace record_put_object_stage_duration with record_stage_duration in
metacache_set, store_list_objects, and bucket_lifecycle_ops to avoid
polluting PUT-specific dashboards with listing/lifecycle timings
- Fix flaky test: serialize tests mutating PUT_STAGE_METRICS_ENABLED with
METRICS_FLAG_LOCK mutex and explicitly set desired state at test start

* fix(bucket-repl): persist MRF retry queue to disk and reload on startup
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(bucket-repl): address three blocking MRF issues from review
1. MRF replay loses delete operations — add `MrfOpKind` discriminator to
`MrfReplicateEntry` (Object | Delete, default=Object for backward
compat). `DeletedObjectReplicationInfo::to_mrf_entry` now persists
`op=Delete`, `version_id`, `delete_marker_version_id`, and
`delete_marker`. `start_mrf_processor` branches on `op`: delete
entries skip `get_object_info` and replay via
`schedule_replication_delete` with `ReplicationType::Heal`; object
entries follow the existing heal path.
2. `flush_mrf_to_disk` cleared the in-memory batch even on encode/write
failure — changed return type to `bool` and callers now only
`pending.clear()` on `true`, so a transient storage error retries
on the next tick instead of silently dropping the batch.
3. Add focused tests: encode/decode roundtrips for object, delete-marker,
versioned-delete, and mixed-batch entries; a routing test confirming
op-kind propagates correctly and that the default is Object for
legacy files; a legacy-compat test verifying old entries round-trip
cleanly through the new format.

* style: fix clippy redundant-clone in MRF tests
Replace &[entry.clone()] with std::slice::from_ref(&entry) in two
encode_mrf_file call sites flagged by clippy's redundant_clone lint
under --all-targets --features rio-v2.

* test(bucket-repl): strengthen legacy MRF compat test with hand-built msgpack
The previous mrf_legacy_file_without_op_field_decoded_as_object test
round-tripped through encode_mrf_file, so it exercised the new format
and never touched a truly-legacy payload.
Replace it with a hand-built msgpack payload that genuinely omits the
"op", "deleteMarker", and "deleteMarkerVersionID" keys — exactly what
the old binary would have written before MrfOpKind existed. The test
now fails if #[serde(default)] is removed from the op field, which
proves real backward compatibility rather than round-trip stability.

fix(bucket-repl): honor op_type in replicate_object so ExistingObject resync respects DISABLED targets
replicate_object was calling filter_target_arns with hard-coded
op_type: Object and existing_object: false regardless of what was
stored in roi.op_type. This meant that a resync worker setting
roi.op_type = ExistingObject (resync_bucket, line 889) had no effect
on target filtering: all configured targets were included, even ones
whose rule had ExistingObjectReplicationStatus::DISABLED.
Fix: pass op_type: roi.op_type and derive existing_object from it
(true only for ExistingObject, not Heal — Heal intentionally bypasses
the existing-object opt-out to repair past failures).
Also add warn! logs at all four MRF channel-overflow sites that were
previously silently returning Missed with no observability.
Verified with a live two-instance test: after resync, objects reached
the ENABLED target and were correctly blocked from the DISABLED target.

* fix(site-repl): clamp replication_cfg_mismatch to owning deployments and add resync status branch
Fix 3: replication_cfg_mismatch was set on ALL deployments for a bucket when
any replication-config discrepancy existed, even on deployments that simply have
no config. mc computes "in sync" as max_buckets minus per-deployment mismatch
entries; with N deployments all flagged for 1 bucket, the result underflows to
1-N = -1. Now only deployments that own a replication config are flagged.
Fix 4: SiteReplicationResyncOpHandler accepted "start" and "cancel" but returned
an empty body (and later a parse error on the client) for any other operation
string. Add a SITE_REPL_RESYNC_STATUS="status" arm that returns the stored
SRResyncOpStatus or an explicit {"status":"not-found"} object so mc never sees
an unexpected end of JSON input.

* fix(site-repl): derive sync_state from reachability and replication rule completeness
PeerInfo.sync_state was set to SyncStatus::Unknown at every construction site
and never updated from real signals. build_status_info now tracks which peers
were reachable during the metainfo fetch phase and, after all bucket stats are
merged, derives sync_state as:
- Enable : reachable AND no replication_cfg_mismatch for any bucket
- Disable : reachable BUT at least one bucket has incomplete/missing rules
- Unknown : unreachable (fetch failed)
The "Sync" column in mc admin replicate status will now reflect actual state
rather than always showing Unknown.

* fix(site-repl): add SRRotateServiceAccountHandler for split-brain svc-acct repair
When site-replicator-0 gets desynced (different secret on different peers), calls
via the old service account return 403, blocking remove and replicate operations
with no in-band recovery path.
SiteReplicationRemoveHandler already purges local state unconditionally before
sending peer notifications, so force-remove works locally even when peers reject
the 403. The new POST /v3/site-replication/rotate-svc-acct endpoint provides the
missing recovery path: it generates a fresh service-account secret, applies it
locally, and pushes a peer/join to every member. Each peer's SRPeerJoinHandler
accepts the join idempotently (update if exists, create otherwise), repairing the
desynced credential without a full teardown + restart.

* fix(site-repl): back-fill pre-existing buckets and objects on replicate add
SiteReplicationAddHandler and SRPeerJoinHandler both called persist_site_replication_state
and returned success without doing anything for buckets that existed before the
sites were linked. Only buckets created after the link (via site_replication_make_bucket_hook)
ever replicated.
Introduce backfill_existing_buckets_after_add which, after persisting the new
state, iterates every local bucket and:
1. Ensures versioning is enabled (required by replication).
2. Reconciles bucket targets so a target entry exists for each remote peer.
3. Reconciles the replication config so a rule pointing to each peer is present.
4. Broadcasts a make-bucket-hook to peers (idempotent) so they create the bucket.
5. Kicks start_site_bucket_resync toward every remote peer so pre-existing
objects travel across.
Errors per bucket are logged but never abort the overall add — manual resync
remains available as a fallback. Both the initiator and the receiving (join) side
run the backfill so convergence happens regardless of which side held data first.

* fix(site-repl): reconcile replication config to restore bidirectional replication
Root cause: ensure_site_replication_bucket_replication_config bailed with Ok(())
the moment any replication config was found on the bucket. When bucket B was
propagated to site-2 via the make-with-versioning bucket-op, site-2's
configure-replication step loaded the freshly-written config and immediately
returned, never adding the reverse-direction rule pointing back to site-1. Result:
objects uploaded to site-2 failed with "replication head_object fallback failed
... service error" because no rule targeted the originating site.
Fix: drop the early-return. Instead load the existing rules, build the full
desired config via build_site_replication_config, and MERGE — adding only the
rules that are absent (identified by their "site-repl-<deployment_id>" id). Re-
number priorities after each merge to avoid conflicts. Existing non-site-repl
rules are preserved. The write is skipped entirely when all desired rules are
already present, so repeat calls remain cheap.
Together with Fix 1 (backfill), any file written to ANY member now replicates to
ALL members. The offline-and-recover case also benefits: when a peer returns,
the per-bucket rules are complete and the resyncer can catch up.
Also register the new rotate-svc-acct route in route_policy and
route_registration_test so the route inventory assertions stay green.

* fix(replication): remove broken resync worker-signal gate
The resync_bucket task opened a new broadcast receiver via
worker_rx.resubscribe(), which positions the receiver at the current
write-head of the ring buffer — past all 10 bootstrap signals written
in ReplicationResyncer::new(). Every spawned resync task therefore
blocked on recv() forever, making `mc admin replicate resync start`
report "started" while no objects ever moved.
Remove the dead wait entirely. Each resync_bucket call is already
spawned on-demand (tokio::spawn in start_bucket_resync / load_resync),
so no additional gate is needed. The per-object concurrency limit is
already enforced by the inner mpsc worker channels (line ~877). Also
remove the now-dead worker_tx/worker_rx fields, bootstrap loop, and
signal-send in resync_bucket_mark_status.
