* perf(put): add eager path metrics and isolation tooling
* fix(decommission): persist progress adaptively (#3497)
Persist decommission progress after either the existing time interval or a migrated-item threshold, and flush progress baselines after bucket and terminal-state saves.
Also stabilize the OIDC discovery mock used by the pre-commit gate.
* refactor: move bucket operations contract (#3507)
* fix(s3): handle multipart flexible checksums (#3508)
* 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).

* 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

* perf(erasure): remove UUID from clone + increase encode inflight budget
Two targeted optimizations for the erasure encoding hot path:
1. Erasure::clone() no longer generates Uuid::new_v4() per clone.
The _id field is unused in the hot path; reusing the original ID
eliminates a CSPRNG call per block encode (100 calls for a 100MB
object with 1MB blocks).
2. Default RUSTFS_ERASURE_ENCODE_MAX_INFLIGHT_BYTES raised from 8MB
to 32MB. This increases the encode pipeline depth from ~5 to ~20
blocks, allowing more read-ahead between the encoder and disk
writer stages. The per-request memory bound is still controlled
by the 8-block hard cap and the env var override.
3. Added encode_data_owned() utility method for zero-copy encoding
when the caller already owns a heap buffer (Vec<u8> → BytesMut
via Bytes::try_into_mut). Not used in the hot path yet but
available for future callers.
All 1157 ecstore tests pass. Criterion micro-benchmarks show no
regression (< 2% variance). Single-machine warp E2E tests were
inconclusive due to high variance; a dedicated multi-disk test
environment is needed for reliable E2E comparison.

* fix(ecstore): remove dead _buf field from Erasure struct
_buf was allocated in new(), clone(), and Default but never read or written.
Each clone() was allocating block_size bytes (typically 10MB) for nothing.
- Remove _buf from struct, Default, Clone, new_with_options
- 51 erasure tests pass
* fix: remove empty line after doc comment

* fix(rio): reject bytes beyond hard limit
* fix(ecstore): reject zero-sized erasure blocks
Object repair rebuilt missing data shards but left missing parity shards unrecreated. A parity-only repair could therefore complete without restoring the shard contents.
Add a repair-specific reconstruction path that regenerates parity after data shards are available, while keeping normal read decoding data-only. Also shut down repair writers after all blocks are written.
Constraint: Preserve read-path decode behavior and limit parity regeneration to repair.
Confidence: high
Scope-risk: moderate
Directive: Do not route read decoding through parity regeneration without measuring the cost.
