* feat(ecstore): add object lock diagnostics
Add configurable namespace lock diagnostics for object operations so production contention can be traced by operation, owner, and key.
Wrap object read/write lock acquisition in diagnostic guards across get, head, put, delete, copy, and multipart flows, and log slow acquisition and long hold durations behind new RUSTFS_OBJECT_LOCK_DIAG_* settings.
Verification:
- make pre-commit
* feat(obs): expose object lock diagnostics metrics
Add Prometheus metrics and Grafana panels for object namespace lock diagnostics, covering slow acquire counts, slow hold counts, acquire duration, hold duration, and the diagnostics-enabled state.
Adopt PR review feedback by keeping diagnostic guards alive through the guarded operation so long-hold warnings and metrics are emitted, reusing shared env helpers, and reducing default-path overhead when diagnostics are disabled.
Verification:
- cargo check -p rustfs-ecstore -p rustfs-io-metrics
- cargo test -p rustfs-ecstore store::object -- --nocapture
- make pre-commit
* perf(obs): reduce object lock diag overhead
Avoid repeated environment parsing on hot object-lock paths by caching the diagnostics-enabled flag, and stop allocating label strings for object lock metrics by recording static labels directly.
Strengthen io-metrics tests by using a local recorder and asserting that the expected object lock diagnostic counters, gauges, and histograms are emitted.
Verification:
- cargo check -p rustfs-ecstore -p rustfs-io-metrics
- cargo test -p rustfs-io-metrics -- --nocapture

* fix(lock): isolate retry attempt lock ids
Generate a fresh lock id for each distributed lock retry attempt so late pending cleanup from an earlier attempt cannot release a lock acquired by a later retry.
Also add a regression test covering late-success cleanup versus retried acquisition.
* style(lock): normalize retry race regression test
Normalize the distributed lock retry race regression test formatting without changing behavior.
* test(lock): remove quorum-order assumption
Make the retry race regression test assert the safety property without assuming which delayed client enters the retry quorum first.
* fix getobject content length resp
* Fix regression in exception handling for non-existent key with enhanced compression predicate and metadata improvements (#915)
* Initial plan
* Fix GetObject regression by excluding error responses from compression
The issue was that CompressionLayer was attempting to compress error responses,
which could cause Content-Length header mismatches. By excluding 4xx and 5xx
responses from compression, we ensure error responses (like NoSuchKey) are sent
correctly without body truncation.
