* 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 (#4417)
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

* fix(migration): decrypt MinIO IAM & server config on drop-in migration
MinIO encrypts IAM identity/service-account files and the server config at
rest with a key derived from the root credentials. The drop-in migration
paths read those blobs from the legacy `.minio.sys` bucket and parsed them
as plaintext JSON, so any encrypted blob failed to parse and was silently
skipped with "incompatible format". This is why users migrating from MinIO
kept their buckets/objects/policies but lost users and access keys (#2212).
The IAM load path already knows how to decrypt these blobs (RustFS master
keys plus MinIO-compatible legacy keys derived from the root credentials),
but that logic lived behind a private method and was never used by the
migration paths. Expose it as `rustfs_iam::try_decrypt_iam_blob` and inject
it into both migration paths via a `LegacyBlobDecryptFn` callback (ecstore
cannot depend on the IAM crate, so the closure is wired in the binary crate).
When a blob cannot be decrypted the raw bytes are used as-is, preserving the
previous plaintext-only behavior with no regression.
Also improve object-layer migration observability without changing control
flow: `try_migrate_format` now distinguishes "no legacy format" (a normal
fresh install) from "legacy format present but incompatible", and the caller
logs a loud error before initializing a fresh format that would leave the
existing MinIO objects unreadable. Topology/version skip reasons are promoted
from debug to warn.
Fixes a pre-existing test isolation race by marking
`test_recovery_falls_back_to_default_config_when_blob_stays_corrupt` serial,
since it reads a process-wide env var toggled by a sibling test.

* test(ecstore): stabilize concurrent multipart resend lock timeout
concurrent_resend_same_part_commits_one_generation spawns 6 same-part
resends whose cross-disk commits serialize on the per-uploadId commit
lock. Under the full nextest suite the parallel disk load pushes those
serialized commits past the small default lock-acquire timeout (5s),
producing a spurious `Lock(Timeout ...)` unrelated to the property under
test (observed on CI at 5.775s vs ~0.5s in isolation).
Raise RUSTFS_OBJECT_LOCK_ACQUIRE_TIMEOUT to the production default (30s)
for the concurrent-commit section via temp_env, so the regression guard
reflects correctness (exactly one intact generation) rather than disk
latency under CI load. The meaningful assertions are unchanged, and
#[serial] keeps the process-wide env override isolated.
Co-Authored-By: heihutu <heihutu@gmail.com>
* fix(lock): bound fast-lock notification wait to prevent lost-wakeup stall
The real cause of the concurrent_resend_same_part_commits_one_generation
failures was a lost wakeup in the fast-lock slow path, not disk latency:
raising the acquire timeout to 30s only delayed the failure (it then timed
out at 30s), proving a genuine stall rather than overload.
In acquire_lock_slow_path a waiter that reaches the notification phase did a
single `timeout(remaining, wait_for_write())` spanning the whole acquire
budget, and treated that wait's elapse as a hard `Timeout`. But the release
path only notifies when `writer_waiters > 0`, so if the holder releases in
the gap after the waiter's `try_acquire` fails and before it registers as a
waiter, no notification (and no stored permit, since the pooled `Notify` is
gated) is produced. The waiter then blocks until the deadline even though the
lock is free and stays free — a spurious lock-acquire timeout. The shared
process-wide notify pool makes it worse: a wakeup can be consumed by a waiter
of a different lock hashing to the same slot.
Bound each notification wait (NOTIFY_WAIT_CAP = 50ms) and, on elapse, loop
back and re-`try_acquire` instead of returning `Timeout`; the deadline check
at the top of the loop is the single source of truth for timing out. A
lost/stolen wakeup now degrades to bounded re-polling (acquire within ~50ms
of the lock becoming free) instead of stalling for the whole timeout.
Correctness (mutual exclusion) is unchanged — acquisition still only happens
via `try_acquire_*`.
Add a regression test that reproduces the stall (holder + late waiter across
many keys): it times out without the fix and passes in ~1s with it. Revert
the earlier acquire-timeout workaround in the multipart test now that the
underlying stall is fixed, so it runs under the default timeout again.

* perf(ecstore): replace linear merge scan with k-way heap and drop clone-to-parse (backlog#874 backlog#875)
merge_entry_channels advanced the k-way merge with a linear scan over all
channel heads (O(entries x channels)) and allocated two fresh Strings per
pairwise comparison via path::clean. Every step also cloned MetaCacheEntry
values, including entry.clone().xl_meta() clone-to-parse calls.
- Introduce MergeHead with a cached cleaned name (allocated only when the
raw name is not already clean) and drive the merge with a BinaryHeap of
boxed heads: O(log channels) per entry, allocation-free comparisons.
- Move entries through the merge instead of cloning; the winner is sent
without an intermediate copy.
- Remove the dead merge_file_meta_versions block: it only ran for
prefix-dir groups whose entries have empty metadata, so xl_meta() always
failed; cross-drive version merging happens in the resolve path.
- Keep legacy same-name semantics (dir groups collapse, objects shadow
prefix dirs, later object candidate wins) and add regression tests for
interleaved ordering, dir/object precedence, uncleaned-name grouping,
and prefix-dir collapse.

* fix(ecstore): honor ascending versions_sort in ListObjects walk (#4348)
* fix(ecstore): honor ascending versions_sort in walk and document ordering invariant (backlog#876)
The walk loop carried a bare `//TODO: SORT` inside the
`WalkVersionsSortOrder::Ascending` branch, so the requested ascending
order was silently ignored and versions streamed newest-first (the raw
FileMeta order). WalkOptions defaults to Ascending, so every default
walker -- notably replication resync, which replays versions and needs
oldest-first to preserve the version-stack order -- received the exact
opposite of the contract.
FileMeta maintains versions newest-first (sort_by_mod_time is
descending) and into_file_info_versions preserves that order, so
ascending emission is the exact reverse of file_info_versions output.
Reverse in place when ascending is requested and add a regression test
locking the newest-first invariant plus the reversal contract.
Key-ordering audit result (no gap found): per-disk walkers emit sorted
streams, merge_entry_channels performs an ordered k-way merge, and
gather_results only filters by marker/limit, so ListObjects key order is
guaranteed upstream and needs no post-sort.

* perf(ecstore): enable GET metadata early-stop by default (#4349)
* perf(ecstore): enable GET metadata early-stop by default with env opt-out (backlog#872)
The metadata early-stop fanout (read_all_fileinfo_early_stop) has been
implemented and instrumented for a while but stayed behind an opt-in
flag, so default GETs always waited for every disk to answer the
metadata read even after quorum agreement was reached.
Flip RUSTFS_GET_METADATA_EARLY_STOP_ENABLE to default-on. The gate stays
conservative: should_allow_metadata_early_stop only admits metadata-only
reads (read_data=false) without version_id, healing, or free-version
requirements, everything else falls back to the full-wait fanout, and
setting the env var to false restores the old behavior entirely. The
version-aware gate (RUSTFS_GET_METADATA_VERSION_EARLY_STOP_ENABLE)
remains opt-in because versioned reads carry a higher stale-selection
risk profile.
Also replace the stale "optimize concurrency" TODO in
get_object_fileinfo with a pointer to the early-stop implementation and
add regression tests for the new default plus the explicit opt-out path.

* perf(ecstore): lazily construct codec streaming multipart readers (#4350)
* perf(ecstore): lazily construct codec streaming multipart part readers (backlog#871)
get_object_decode_reader_with_fileinfo opened shard readers for every
part of a multipart object before returning the streaming reader, so
TTFB paid for parts x disks file opens up front and an early client
disconnect wasted the setup work for every unread part.
Replace the eager loop with LazyMultipartCodecStreamingReader: the first
part is still built eagerly so the dominant fallback conditions (missing
shards / read quorum) are detected before any byte is streamed and the
whole request can fall back to the legacy duplex path exactly as before.
Each subsequent part is built on demand -- when the previous part hits
EOF -- via a spawned task handle owned by the reader; dropping the
reader aborts an in-flight build so disconnects stop all further IO.
If a later part hits a fallback condition mid-stream (a shard vanished
after the request started), the reader surfaces an explicit read error
with a pipeline-failure metric instead of silently degrading; the
client's retry then detects the condition on the eager first-part setup
and takes the legacy path cleanly.
Adds unit tests for in-order streaming across lazy boundaries, deferred
construction (no build when the client stops within part 1), and the
mid-stream fallback error path.

* perf(ecstore): prefetch next multipart part reader setup during decode (#4351)
* perf(ecstore): prefetch next multipart part reader setup during decode (backlog#870)
get_object_with_fileinfo processed multipart parts strictly serially:
the next part's bitrot reader setup (file opens + read-quorum wait
across all disks) only started after the current part finished
decoding, so large multipart reads paid full setup latency between
every part.
Overlap the two stages with a depth-one pipeline: right after the
current part's readers are obtained, the next part's setup is spawned
(shared inputs behind Arc) and joined when the loop reaches that part.
The shared setup_multipart_part_readers helper keeps stage-duration
metrics semantics identical for both paths; a failed or stale prefetch
falls back to the synchronous setup, and the PrefetchedReaderSetup
guard aborts the in-flight task on error returns, early breaks, or
caller drop so disconnects stop background disk IO.
Gate: RUSTFS_GET_MULTIPART_READER_SETUP_PREFETCH (default on, env
opt-out). Adds a three-part end-to-end read test covering the prefetch
hit path and cross-part content ordering.

* perf(ecstore): move FileInfo through GET shuffle instead of cloning (#4352)
perf(ecstore): move FileInfo entries through the GET shuffle instead of cloning (backlog#873)
shuffle_disks_and_parts_metadata_by_index deep-cloned every valid
FileInfo (parts, erasure info, metadata map) once per disk on each GET.
Add an ownership-taking variant that runs the same by-index consistency
check as a read-only first pass and then moves entries into their
shuffled slots with mem::take, and switch get_object_with_fileinfo to
it -- that call site already owned the parts metadata vector. Disk
handles are Arc clones and stay cheap.
Scope notes from the backlog#873 audit:
- get_object_fileinfo's disks.clone() stays: DiskStore is Arc<Disk>, so
the clone is per-slot refcounting and correctly avoids holding the
RwLock read guard across the metadata fanout awaits.
- get_object_decode_reader_with_fileinfo keeps the borrowing shuffle:
its caller must retain files/disks for the legacy fallback path, so an
owned variant would just shift the same clone upstream.
- The metadata-cache hit path still clones parts_metadata; sharing the
cached entry via Arc changes the read-path return types and is left
as a follow-up.
Equivalence tests cover both the by-index placement and the mod-time
fallback against the borrowing variant.

* fix(ecstore): gate merge emission on cleaned key and clear clippy redundant_clone
Address review + CI findings on the ListObjects/GET optimization PR:
- merge_entry_channels gated emission on the raw entry name while the heap
orders by the cleaned key, so entries whose cleaned order and raw byte order
disagree (e.g. redundant slashes) could be dropped. Gate on the same cleaned
sort key the heap uses; add a regression test (`a//c` after `a/b`).
- Drop three redundant `.clone()` calls in test code flagged by
clippy::redundant_clone (owned-shuffle equivalence tests and the walk
ascending-versions contract test) that failed the CI clippy gate.
- Document the known mid-stream fallback limitation of the opt-in multipart
codec streaming reader (default off) and mark the in-place per-part legacy
degradation as a follow-up.

* fix(ecstore): force full metadata fanout for object tagging writes (backlog#872)
put_object_tags reads the object fileinfo with read_data=false and then
writes the updated tags to the online-disk set that read returned. With
metadata early-stop enabled by default, that read now returns as soon as
read quorum is reached, so the online-disk set is only a read-quorum
subset. Writing tags to that subset fails write quorum -> ErasureWriteQuorum
-> S3 SlowDown, which is exactly the s3-tests tagging failures
(PutObjectTagging/DeleteObjectTagging, reached max retries).
Thread a caller-controlled `allow_early_stop` gate through
read_all_fileinfo_observed/_inner and add get_object_fileinfo_gated;
put_object_tags calls it with allow_early_stop=false so the metadata read
does the full quorum fanout and returns the complete online-disk set as
the write target. Pure-read callers (GET/HEAD/tag read) keep the
early-stop fast path unchanged.
Extract metadata_early_stop_permitted() as the single gate and add a unit
test locking the invariant: caller opt-out (and observe=false, and data
reads) never early-stop even with the env flags on.

Three tests share the global list-objects mutation-sequence state (the
LIST_OBJECTS_MUTATION_SEQUENCE atomic and the per-bucket sequence map)
and all call reset_list_objects_mutation_sequences_for_test(), but only
observed_mutation_persists_namespace_journal_high_water was marked
#[serial_test::serial]. The serial lock only excludes tests that also
carry the attribute, so the unmarked tests still ran concurrently with
it: the journal test's persist of "bucket" -> 11 could land after the
recovery test's reset, making it observe 11 instead of the expected 9
(flaky under the default multi-threaded test runner, green with
--test-threads=1).
Add #[serial_test::serial] to the two unmarked tests:
- persistent_key_only_index_load_recovers_mutation_sequence_from_journal
- list_objects_mutation_sequence_advances_per_bucket
Unique bucket names alone would not fix this: the per-bucket assertions
in list_objects_mutation_sequence_advances_per_bucket check exact values
produced by the single global atomic counter, which any concurrent
observe call perturbs, and every reset zeroes that global state for
whichever peer is mid-flight.

Second TODO-convergence round over the current tree (backlog#646). All
line numbers in the old inventory had gone stale after the set_disk /
diagnostics / cluster refactors, so this re-scans and reduces the marker
count from 144 to 99.
STALE removals (comment describes already-implemented behavior, or dead
commented-out blocks) across ecstore (set_disk ops/core, store,
cluster/rpc, bucket/metadata_sys, services), iam, filemeta, s3select and
rustfs auth/object_usecase. No behavior change.
Safe fills, each verified:
- filemeta: replication_info_equals now also compares
replication_state_internal (function currently has no callers; adds a
regression test).
- bitrot: drop the confirmed-unused `_want` parameter from bitrot_verify
and the now-unused `sum` on LocalDisk::bitrot_verify, removing a
Bytes::copy_from_slice allocation. Streaming verify uses the file's
embedded per-shard hash, never the passed sum.
- signer: rename v4_ignored_headers -> V4_IGNORED_HEADERS and drop the
non_upper_case_globals allow.
- admin/heal: test_decode was #[ignore]d and used serde_urlencoded on a
JSON body (would panic); rewire to serde_json::from_slice to match the
production decode path, add assertions, un-ignore.
Verified: cargo fmt; cargo check on touched crates; tests pass
(filemeta, signer, bitrot, heal::test_decode); arch guardrail scripts
pass.
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.

Address review feedback: unwrap_or_default() silently substituted a nil
UUID when latest metadata lacked data_dir. Delete markers and remote
