* 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 (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).

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

PR #4220 added a purge for orphan empty-directory trees (folder keys with
no xl.meta) on the delete path, but the guard only accepted
object-not-found. Over the real HTTP DELETE path the guard is never
reached: `del_opts` pins `version_id = Uuid::nil()` for directory keys, so
the missing dir object fails the specific-version lookup with
version-not-found (FileVersionNotFound), not object-not-found. The guard
short-circuits, the store returns the error, and the API layer turns it
into a fake 204 — the ghost folder survives, exactly the #4189 symptom.
The existing unit tests passed because they call
`purge_orphan_dir_object` directly, bypassing the nil-version lookup.
Accept both misses in the guard (extracted as
`should_purge_orphan_dir_on_missing`) so the folder delete actually takes
effect. Non-directory keys and non-miss errors (e.g. quorum failures) are
unaffected; the cross-disk data-safety refusal in
`purge_orphan_dir_object` is unchanged.
Verified end-to-end against a running 4-disk erasure server: DELETE of a
planted orphan `ghost/` tree now purges it on all drives and clears the
listing, a real object under the same prefix is untouched, and a prefix
holding real data on any drive is refused (all drives preserved).
Adds predicate regression tests covering version-not-found /
object-not-found on directory keys, and the negative cases.

fix(ecstore): purge orphan empty-directory trees on folder delete (#4189)
Empty "phantom" folders — on-disk directory trees with no xl.meta
anywhere — show up in listings as common prefixes but cannot be removed
by any S3 call: DeleteObject on the folder key encodes it to __XLDIR__,
finds no metadata, and returns NotFound, which the API layer masks as a
fake 204 while the tree survives on disk.
Make handle_delete_object attempt a guarded purge when a dir-object key
resolves to NotFound:
- sweep every erasure set of every pool (orphan fragments can sit on
any set, left behind by whichever sets stored the deleted children)
- per set, refuse if ANY disk holds a regular file under the prefix,
so degraded/healable objects are never destroyed
- remove empty directories children-first with non-recursive deletes;
a racing PutObject makes the rmdir fail with DirectoryNotEmpty and
the entry is skipped
This state is unrepresentable on AWS S3 (CommonPrefixes derive only
from real keys; DeleteObject is an idempotent 204), so the purge moves
visible behavior closer to S3. It deliberately goes beyond MinIO, whose
DeleteObject leaves these trees stranded and whose heal only removes
dangling (minority-presence) dirs — a long-standing complaint
(minio/minio#15257, #19516, #18444).
Also move the test-only content_matches_by_etag import in
replication_target_boundary.rs into the cfg(test) module; it failed
cargo clippy -D warnings and blocked the pre-PR gate.

* fix(ecstore): skip hidden metadata in walk limit
* fix(ecstore): match walk limit to visible versions
* fix(ecstore): avoid decoding all versions for limit
* fix: return 503 on lock contention instead of 500
When concurrent PUTs to the same key contend for the namespace write
lock, lock timeout and conflict errors were wrapped as
StorageError::other(...) → StorageError::Io(...), which fell through
to S3ErrorCode::InternalError (500) in the error mapping.
Only QuorumNotReached was correctly mapped to ServiceUnavailable (503);
all other lock errors (Timeout, AlreadyLocked, etc.) became 500.
Fix: map_namespace_lock_error now returns StorageError::Lock(err) for
non-quorum lock errors, and StorageError::Lock is mapped to
S3ErrorCode::ServiceUnavailable in the HTTP error conversion.
Affected paths:
- crates/ecstore/src/set_disk/lock.rs
- crates/ecstore/src/store/object.rs
- crates/ecstore/src/store/bucket.rs (make_bucket, delete_bucket)
- rustfs/src/app/object_usecase.rs (copy_object)

* fix(tier): stop sending nil/garbage versionId to warm backend S3
Three bugs caused NoSuchVersion errors when reading tiered objects:
1. warm_backend_s3sdk: GET and DELETE ignored rv/range opts entirely —
fixed to forward version_id and byte-range to the SDK request.
2. version.rs (MetaObject + MetaDeleteMarker): transition_version_id was
parsed with unwrap_or_default(), turning invalid/wrong-length bytes
into Uuid::nil(). The nil UUID was then serialized and sent as
?versionId=00000000-... to the tier backend -> NoSuchVersion.
Fixed: .and_then(.ok()).filter(!is_nil()) so only valid non-nil UUIDs
are forwarded as versionId.
3. bucket_lifecycle_ops: add debug/error logs in
get_transitioned_object_reader to record tier, tier_object, and
tier_version_id before and on failure of the tier GET.
Also adds tier transition fields to dump_fileinfo example for offline
xl.meta inspection, and fixes Docker build (cargo path + entrypoint).
Adds CLAUDE.md with tier architecture and debugging notes.

* 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
