fix(get): bound GET disk-read admission with a hard cap instead of unbounded permit bypass (#4935)
Refs https://github.com/rustfs/backlog/issues/1317 Previously, when the primary disk-read permit pool stayed saturated past `RUSTFS_OBJECT_DISK_PERMIT_WAIT_TIMEOUT` (default 5s) — which a handful of slow clients can cause because a permit is held for the whole body transfer — the GET path set `disk_permit = None` and continued reading with no admission token at all. That made the disk-read concurrency limit unbounded under exactly the overload it is meant to protect against: any number of GETs could pile onto the disks simultaneously. This replaces the permit-less bypass with a bounded overflow lane and a hard cap: - A new bounded degraded semaphore (`RUSTFS_OBJECT_DISK_DEGRADED_READ_CAP`, default mirrors the primary cap) is consulted only after the primary wait times out. A GET takes one degraded permit without blocking, or is rejected with `SlowDown`/503 once that lane is also full. The total number of GETs performing disk-active reads is therefore hard-capped at `primary_cap + degraded_cap`, and no GET ever reads without holding an admission token. - Admission is centralized in `ConcurrencyManager::admit_disk_read`, returning `Primary`/`Degraded`/`Unbounded`/`Rejected`. `Degraded` and `Rejected` are counted in metrics (`rustfs.get_object.disk_permit.degraded.total`, `rustfs.get_object.disk_permit.hard_reject.total`), replacing the removed `rustfs.get_object.disk_permit.bypass.total`. - A primary cap of `0` (disk-read throttling disabled) is preserved as the only intentional permit-less path via `Unbounded`, so that degenerate-but-served configuration is not turned into all-503. The `primary_wait == 0` wait-forever opt-out is likewise unchanged. Healthy GETs are unaffected: concurrency at or below the primary cap is admitted immediately from the primary pool exactly as before, with no new latency or rejection. The rejection is surfaced before response headers are constructed, so it is a clean pre-header 503, never a post-header 504 masquerade. Degraded-lane GETs use the identical streaming reader and forward-progress stall timeout as primary GETs, so a slow but progressing large download is not killed. Owned permits (primary or degraded) are held by `DiskReadPermitReader` and released on body EOF or client drop/cancel, so tokens are always returned. Body stall timeout already resets on forward progress and post-header failures already surface as body errors, so no timeout-split changes were needed here. Scope: this PR implements the minimal safe correctness core (eliminate unbounded bypass + hard cap + SlowDown). The two-level weighted-fair + aging scheduler (small setup cap feeding a size-aware data-producer fair queue) and the strictly-bounded producer/client buffer with cancellation propagation from the issue plan remain follow-ups. The black-box slow-client soak is deferred to the unbuilt facility in https://github.com/rustfs/backlog/issues/1325 rather than faked. Tests (white-box, virtual clock via `start_paused`): degrade-then-hard-reject with token release; 100 concurrent GETs against primary=1/degraded=1 never exceed 2 simultaneous admissions with every request either admitted or explicitly rejected; disabled cap serves unbounded; zero-wait blocks on the primary lane. Reverting the hard cap makes the concurrency invariant fail. |

fix(ecstore): bound remote shard writers with a progress deadline so one black-hole peer cannot pin write quorum (#4925)
A PUT that fans out erasure shards to remote peers awaited every shard writer to completion on both the per-block write and the final shutdown, and the remote HttpWriter had no progress deadline. A peer that accepts the TCP connection but never drains the request body (or never sends a response) therefore wedges the writer forever once the bounded buffers fill, pinning an otherwise-healthy write quorum indefinitely — a cluster-level write-availability hazard triggered by a single bad peer (rustfs/backlog#1319, https://github.com/rustfs/backlog/issues/1319). MultiWriter now wraps each shard write and each shard-writer shutdown in a forward-progress deadline. The budget is re-armed on every block, so it bounds a stall rather than the total transfer time of a large object: a slow-but-honest writer that keeps completing shards is never killed, while a writer that makes no progress within the budget is failed and its disk dropped before commit. An optional absolute per-object cap (disabled by default) backstops a slow-drip peer that dribbles just enough progress to reset the per-block timer without ever converging; it is off by default so a legitimate large upload over a slow link is not killed on total time alone. Both knobs come from RUSTFS_OBJECT_DISK_WRITE_STALL_TIMEOUT (default 30s) and RUSTFS_OBJECT_DISK_WRITE_ABSOLUTE_CAP (default 0 = disabled); setting the stall timeout to 0 restores the previous wait-forever behavior for a conservative rollback. The deadline enforcement lives in MultiWriter (writer-agnostic), so it covers local and remote writers alike and keeps the existing control-flow shape: a timed-out shard is marked failed (Error::Timeout, which is not an ignored error) and excluded from the write quorum exactly like any other shard write failure, and the unchanged nil_count/quorum check then continues on quorum or fails cleanly. This deliberately stays out of the MultiWriter lifecycle / commit-coordinator territory owned by rustfs/backlog#1312. When a stalled writer is dropped to fail its shard, the remote HttpWriter must stop holding the connection and its buffered body. HttpWriter previously left its spawned request task running on drop; it now aborts that background task in Drop (it is no longer pin-projected, since every field is Unpin and the AsyncWrite impl already used get_mut). Bytes already handed to the transport cannot be unsent, but they land only in this upload's unique tmp path and are reclaimed by tmp GC — they never touch a committed object. Tests, all on a paused virtual clock so they are deterministic and non-flaky: - one black-hole writer still meets a 3/4 write quorum without hanging; two black holes fail the quorum cleanly (both for the per-block write and the shutdown paths). - a slow-but-honest writer that keeps making progress within the stall budget is never failed across many blocks. - the absolute cap bounds a slow-drip writer within a finite budget while the healthy writers keep quorum. - the default policy is armed by default and honors 0 as disabled. - HttpWriter aborts its background request task on drop against a hanging peer. The toxiproxy/black-hole 4x4 end-to-end acceptance depends on black-box test facilities from rustfs/backlog#1325, which are not built yet; that acceptance is deferred to #1325 and intentionally not faked here. |

perf(get,heal): fix GET hot-path overhead and heal checkpoint scaling (#4237)
perf(get,heal): land verified fixes for backlog #800-#804 Five fixes from the GET-path performance audit and scanner/heal completeness audit (rustfs/backlog#800..#804), each verified locally: - backlog#800 (heal checkpoint O(N^2)): ResumeCheckpoint object sets are now HashSet (Vec::contains was O(n) per healed object; 1.5ms at n=1M vs 11ns measured), and per-object checkpoint/resume-state persistence is batched (1000 mutations / 5s) instead of rewriting the whole file per object. complete_page() prunes the sets at page boundaries so memory stays bounded; positions still persist unconditionally and legacy Vec-format checkpoints still deserialize. - backlog#801 (DiskInfo.healing never set): erasure-set heal now writes a healing marker (.rustfs.sys/healing.bin) on the disks it rebuilds (endpoints plumbed via HealRequest/HealTask.heal_endpoints from the auto disk scanner) and clears it on success. LocalDisk::disk_info surfaces the marker, so scanner heal coordination, lock selection and admin/metrics healing counts see the rebuild. - backlog#802 (cache probe after data read): new GetObjectBodyCacheHook in ecstore lets the app-layer object data cache serve the body inside get_object_reader, after metadata quorum resolution (etag known) but before the erasure shard read/decode. Previously a hit still paid the full disk read. Hook is None/no-op when the cache is disabled. - backlog#803 (GET hot-path redundant work): ObjectInfo is cloned for event notification only when an event will actually be built (GET and HEAD paths; events are currently suppressed so the clone was pure waste); get_opts/put_opts/del_opts resolve bucket versioning with one metadata-sys lookup instead of two; skip_verify_bitrot and get_lock_acquire_timeout env reads are cached via OnceLock; the io-priority metric is no longer double-counted; GetObject input fields are cloned selectively instead of cloning the whole input. - backlog#804 (disk permit starvation): the disk-read permit wait is now bounded (RUSTFS_OBJECT_DISK_PERMIT_WAIT_TIMEOUT, default 5s, 0 = previous unbounded behavior); on timeout the GET proceeds without a permit and the bypass is counted. DiskReadPermitReader also releases the permit at body EOF instead of holding it until the client drops the stream. Verification: make pre-commit; cargo clippy -D warnings on the four changed crates; full rustfs lib suite (2096 tests) green; rustfs-heal lib suite green with new unit tests for checkpoint pruning/legacy format/throttle, permit EOF release, and the cache hook (hit + SSE skip). The heal_integration_test and one set_disk listing test fail identically on unmodified main (pre-existing global-state ordering flakes, verified via git stash A/B).

feat(ecstore): add object lock diagnostics (#3178)
* 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 - make pre-commit |
