Chris LuandGitHub e7be6bb2f8 filer: allow clearing a bucket read-only flag stuck after quota removal (#10310)
* filer: allow clearing a bucket read-only flag stuck after quota removal

Once s3.bucket.quota.enforce marks a bucket read-only, removing or
disabling the quota orphans the flag: enforcement skips buckets with a
non-positive quota, and fs.configure merges booleans with OR so
-readOnly=false could never turn it off. The only way out was deleting
the whole path rule.

- s3.bucket.quota -op=remove/disable and the admin server quota update
  now lift the read-only flag on the bucket's path rule
- fs.configure now honors explicitly passed false boolean flags
  (-readOnly, -fsync, -worm) instead of OR-merging them away

* filer: ClearBucketReadOnly reports unchanged when the save fails

Chris LuandGitHub b43089f721 s3: keep empty-folder cleanup out of the multipart .uploads staging tree (#10273)
* s3: keep empty-folder cleanup out of the multipart .uploads staging tree

The async EmptyFolderCleaner deleted <bucket>/.uploads once it looked
empty. A concurrent CreateMultipartUpload inserting its marker between
the cleaner's emptiness check and the bulk child delete had its row
wiped, so the upload silently vanished: ListMultipartUploads then omits
it and the following part/complete/copy calls fail. Skip the .uploads
subtree in both the queue and the delete path (including the eager
parent cascade); the multipart upload lifecycle owns it.

* s3: slice the bucket-relative path instead of reallocating it

Chris LuandGitHub 6e477ae00f filer: keep the internal .system folder out of the per-bucket store path (#10248)
* filer: keep .system internal folder in the default SQL table

Bucket-table SQL stores read the first path segment under /buckets as a
bucket name. The ListBuckets owner index lives at /buckets/.system/..., so
every write there hit isValidBucket(".system") == false and returned
"invalid bucket name .system", flooding the filer log on the postgres/mysql
backends. Route dot-prefixed internal folders to the default table by their
full path, like any other non-bucket entry.

* filer: keep .system internal folder in the default leveldb3 DB

Same guard as the SQL stores: leveldb3 would otherwise open a separate DB
for the .system owner-index folder instead of keeping it in the default DB.

* filer: keep .system internal folder under the default ydb prefix

Skips a DescribeTable round trip per operation on the .system owner-index
path, which never resolves to a real bucket table.

* filer: keep .system internal folder in the default arangodb collection

Avoids creating a stray collection for the .system owner-index folder.

Chris LuandGitHub 39ff5ae767 filer: default cassandra2 timeout and ydb prefix so env-var configs match the scaffold (#10234)
* cassandra2: default connection_timeout_millisecond so env-var configs keep the 600ms timeout

The scaffold documents a 600ms default, but the value has no SetDefault. A
config supplied purely through env vars (or a minimal toml) that omits the
key read back 0, silently overriding the client timeout with no bound.

* ydb: default the table path prefix so env-var configs keep the seaweedfs sub-path

The scaffold documents prefix = "seaweedfs", but with no SetDefault a config
that omits it lands tables at the database root instead of under seaweedfs/.

* postgres2: default the filemeta CREATE TABLE when createTable is unset

An empty createTable rendered through fmt.Sprintf produced
%!(EXTRA string=filemeta), which Postgres rejected with a syntax error at

* mysql2: default the filemeta CREATE TABLE when createTable is unset

Same empty-template failure the postgres2 path had: an unset createTable
rendered to %!(EXTRA string=filemeta) and MySQL rejected it at init.
Fall back to a working template.

Chris LuandGitHub ece4f42ecd fix(filer): avoid ReaderCache WaitGroup reuse race between reads and destroy (#10190)
filer: count reader on cacher waitgroup under the map lock

The read's wg.Add(1) ran after ReadChunkAt released the ReaderCache lock, so a
concurrent destroy() (error eviction, LRU, or UnCache) could start wg.Wait() on
a zero counter and then race the Add - a WaitGroup reuse that trips -race and
can panic. Move the Add under the lock, before the cacher can leave the
downloaders map, so a destroy is always ordered against a counted read.

bdcc3154ed refactor: centralize genUploadUrl in UploadOption (#10164)
* refactor: centralize genUploadUrl in UploadOption

Replace inline genFileUrlFn closures with operation.GenUploadUrl field:

- Add GenUploadUrl func(host, fileId) string to UploadOption struct
- Add GenUploadUrlProxy(filerAddress string) utility function
- Remove genFileUrlFn parameter from UploadWithRetry signature
- Update all callers: mount, gateway, mq, filer_copy, filer_sync

This matches the weed mount -filerProxy pattern exactly,
factorizing the URL generation logic across all consumers.

* docker release: run all platform jobs in one wave, cache rocksdb compile

Drop max-parallel so the 13 per-platform builds run together instead of two
waves of 8 (rocksdb was queuing behind the cap and starting ~8 min late).

Keep cache-to mode=max for rocksdb: its RocksDB static_lib compile is
sha-independent, so it caches across releases and stops being the ~16-min
long-pole that gates the merge fan-in. go-build variants stay mode=min.

424cd164e9 s3: invalidate stale reader cache locations on chunk read failure (#10156)
* s3: invalidate stale reader cache locations on chunk read failure

* filer: share the chunk-read self-heal across reader cache and streaming paths

The reader cache retry added a third copy of the invalidate-relookup-compare-retry
dance already inlined in PrepareStreamContentWithThrottler and duplicated in
retryWithCacheInvalidation. Extract retryFetchWithFreshLocations and route all
three through it, parameterized by the refetch primitive.

* filer: drop redundant completedTimeNew store in reader cache success path

startCaching already stamps completedTimeNew unconditionally before the
fetchErr branch; the second store inside the success branch is dead.

* filer: make NewReaderCache cache invalidator an explicit parameter

The variadic ...CacheInvalidator only ever read the first element, so a caller
could pass two and silently get one. Take a single explicit argument and have
the non-S3 callers pass nil.

* filer: inject reader cache chunk fetch as a struct field

Replace the process-global readerCacheFetchChunkData test seam with a
per-instance fetchChunkDataFn field defaulted in NewReaderCache, matching how
lookupFileIdFn is already wired. Tests set the field on the cache instead of
swapping a shared global.

* filer: log the location count, not full URLs, on self-heal retry

Chris LuandGitHub 803c5a8dca fix(filer): use DROP TABLE IF EXISTS in SQL stores (#10158)
Concurrent bucket deletion across multiple filer replicas races on the
per-bucket DROP TABLE. The first replica drops the table; the rest hit
an undefined-table error (postgres 42P01, mysql 1051) which propagates
out of DeleteFolderChildren and panics the filer. On restart the same
pending DROP re-runs and the filer crash-loops.

Make the drop idempotent. Same defect class in all SQL backends, so fix
postgres, postgres2, mysql, mysql2, and sqlite together.

e1f89f85f2 fix(filer): apply -filer.disk default to metadata log assigns (#10080)
* fix(filer): apply -filer.disk default to metadata log assigns

Metadata event log writes call operation.Assign directly and used only
FilerConf path rule DiskType. When filer.conf rules were missing or
unmatched, the master received an empty DiskType and grew volumes on the
built-in hdd layout.

Mirror resolveAssignStorageOption: wire FilerOption.DiskType into the
Filer, fall back when the matched path rule has no disk type, and return
the matched rule from resolveMetadataLogAssignDiskType to avoid duplicate
MatchStorageRule lookups.

* mini: fall back to -volume.disk for filer default disk type

weed server copies -volume.disk into the filer disk default when

Chris LuandGitHub 63f2f0bef5 s3: keep a file promoted to a directory retrievable as an object (#10070)
* filer: treat a directory carrying object data as an S3 key object

A file promoted to a directory by a child write keeps its chunks, inline
content, or remote-tiered entry. Recognize that as a directory key object,
not only when a Mime is set, so the object still lists, demotes on delete,
and is not reclaimed by cleanup like the object it still is.

* filer: keep the empty-folder cleaner from reclaiming a promoted object

The cleaner skips directory key objects, but its check only looked at the
Mime. Mirror the chunks/content/remote check so a file promoted to a
directory is not deleted once its children are gone.

* s3: serve ranged GET for a directory that carries object data

Reject only zero-size directories so a file promoted to a directory streams
range requests instead of returning 404, while empty directories still 404.

* s3: return HEAD metadata for a directory that carries object data

HEAD now 404s a directory only when it has no data, so a promoted object is
retrievable while empty/implicit directories still fall back to LIST.

Chris LuandGitHub 3ccd4ed85c filer: skip COLLATE "C" list fallback on CockroachDB (#10015)
* filer: skip COLLATE "C" list fallback on CockroachDB

CockroachDB string comparison is already byte-ordered, so wrapping the
list queries in COLLATE "C" can never change result order. It reports
datcollate=en_US.utf8 regardless of how the database was created, so the
collation check always misfires and forces the fallback. On 22.1 and
older COLLATE "C" is rejected as an invalid locale, turning every filer
list query into a hard failure. Detect the backend via version() and
keep the default ordering.

* filer: test CockroachDB collation detection

Cover the CockroachDB skip path and the locale-aware Postgres force path
with go-sqlmock.

Chris LuandGitHub 7e13340dcb filer: tolerance-window read pattern detection for concurrent readahead (#9983)
* filer: tolerance-window read pattern detection for concurrent readahead

ReaderPattern detected sequential access via strict contiguity (lastReadStopOffset
== offset). Under concurrent/reordered ReadAt (parallel readahead, which ReadAt
already supports via RLock + atomics), that exact match frequently misses even for
a genuinely sequential stream, drifting toward random mode and disabling prefetch.

Track a read frontier (max offset+size, advanced with a lock-free CAS loop) and
treat a read as sequential when its start is within SeqTolerance (8 MiB) of the
frontier. The window absorbs reordered/concurrent readahead while still rejecting
far random jumps; the existing ModeChangeLimit hysteresis is unchanged. API
(NewReaderPattern/MonitorReadAt/IsRandomMode) is unchanged, so reader_at is
unaffected. Adds reader_pattern_test.go.

* filer: read the read frontier inside the CAS loop

Capture the frontier from the CAS loop's own load rather than a separate
up-front snapshot, so the sequentiality diff is judged against the freshest
pre-image even if a concurrent readahead advances the frontier while we loop.
Also drops the now-redundant load. Mirrors the same fix on the write-side
ReaderPattern twin (review feedback on the companion PR).

* filer: add frontier/boundary/recovery guard tests for ReaderPattern

Mirror the regression guards added to the write-side WriterPattern: assert
the max-frontier never regresses on a backward read (the CAS invariant), pin
both sides of the inclusive SeqTolerance boundary, and verify sustained near
reads recover sequential mode out of the negative floor. Each guards an
invariant the original four tests left uncovered.

Chris LuandGitHub 594fc667d5 Cut per-subscriber replay decode and widen replay concurrency (#9917)
* Filter metadata events before unmarshaling them per subscriber

Every subscriber unmarshaled every log entry into a full event just to
run the path filter, and entries carry complete chunk lists, so a fleet
of path-filtered subscribers spends almost all replay CPU materializing
events it then discards. A shallow wire scan now extracts just the
directory, entry names and rename destination into a skeleton event,
feeds the same matcher, and skips the decode for entries the subscriber
cannot match. Any scan surprise (malformed bytes, merged duplicate
message fields) falls back to the full decode, and the unsynced-events
heartbeat keeps firing for skipped entries.

* Raise the legacy replay cap

The cap was sized when every replay pinned a private chunk reader per
source filer. Replays now share decoded chunks, so sixteen needlessly
serializes subscriber catch-up; the expensive part stays bounded by the
cache's load gate.

* Weight concurrent log-chunk loads by size

The flat eight-load gate let eight tiny chunks through as reluctantly as
eight full ones. Charge each load's chunk size against a 128MB in-flight
budget instead: small chunks decode wide open while full-size ones still
serialize enough to cap the transient peak. Oversized weights clamp to
the budget so they can always acquire.

* Propagate heartbeat send failures and reset the skip counter

A failed heartbeat send means the stream is gone, so end the replay
instead of scanning on. A delivered event also resets the skip counter,
keeping the heartbeat cadence relative to the last thing the client
actually received.

* Share the unsynced-events counter across the prefilter and delivery

Two independent counters could starve the heartbeat: alternating drops
reset each side before either reached its threshold. One shared counter
increments on every dropped entry, prefiltered or not, and only an
actual delivery resets it, restoring the original cadence exactly.

* Tighten comments

* Benchmark the subscription match paths

For a thousand-chunk event that the subscriber filters out, the shallow
scan matches in 10us and 9 allocations against 175us and 4031
allocations for the full decode.

Chris LuandGitHub 2ac5aa72c7 add elastic8 filer store for Elasticsearch 8 (#9916)
* elastic: fix listing against a missing or empty directory index

The refresh 404 leaked into the named return, so the first listing of a
directory whose index does not exist yet returned an error instead of an
empty result. Sorting also fails on an index with no documents
("No mapping found for [_id] in order to sort on"); unmapped_type
keeps the resumed-listing path working there.

* add elastic8 filer store for Elasticsearch 8

Elasticsearch 8 disables _id fielddata by default, so the elastic7
store's directory listings fail with "Fielddata access on the _id
field is disallowed". elastic8 uses the same client and configuration
options, but also indexes the document id as an Id field and sorts
listings on Id.keyword.

Chris LuandGitHub bf76040046 Share metadata-log replays per chunk instead of per file (#9906)
* Share metadata-log replays per chunk instead of per file

Log file chunks are immutable: each metadata-log flush uploads one whole
buffer of complete records as a new chunk, and appends only add chunks.
So cache decoded entries per chunk, with no age gate and no fingerprint
revalidation. The per-file cache excluded files younger than two flush
intervals, which is exactly the hot tail that every tailing or
reconnecting subscriber replays — each through a private chunk reader
holding an 8MB buffer and decoding the whole file from byte zero.

A chunk's flush time also upper-bounds every record timestamp inside it,
so a tail replay now skips cold chunks without reading them at all.

If a chunk does not decode standalone (records spanning chunk
boundaries, or a corrupt size prefix), fall back to streaming the whole
file as one byte stream, resuming after the last yielded entry.

* Evict idle metadata-log cache entries

The replay cache only evicted on insert, so once filled it held its full
budget forever. Stamp entries on use and sweep the LRU tail every minute,
dropping anything untouched for five minutes; the cache now holds memory
only while subscribers actually replay.

* Reject implausible records when decoding log chunks

proto.Unmarshal is permissive: empty payloads and unknown-field garbage
parse without error, so a chunk starting mid-record could decode by
coincidence and get cached instead of falling back to the byte stream.
Enforce what the writer guarantees - records are never empty and carry
strictly increasing positive timestamps within one flushed buffer.

* Gate the singleflight test on an open flight

The sleep alone only probabilistically created concurrent misses; a
started channel now proves the loader holds the flight before callers
are released.

Chris LuandGitHub 9e98ec4b2e Share decoded metadata-log entries across subscriber replays (#9903)
perf(filer): share decoded log entries across metadata replays

Concurrent SubscribeMetadata replays of the same persisted log history each
opened a chunk reader per source filer and re-decoded the same files, so a
reconnect storm multiplied into many GB of buffers. Cache the decoded entries
of completed log files in a bounded LRU, coalescing concurrent loads with
single-flight and bounding concurrent decodes. Each hit is validated against
the file's current chunk set, so a file that received a late append is
reloaded rather than served stale; reads that stop on an unreachable chunk are
delivered but not cached so a transient outage re-probes on the next replay.

Chris LuandGitHub 048f9ece2d Fix filer metadata-replay OOM under mount reconnect storms (#9901)
* fix(filer): propagate multi-filer metadata log read errors

A genuine (non not-found) read error in one filer's log stream was logged
and skipped, then the merged cursor advanced past the gap, silently
dropping that file's events. Abort the whole replay so the subscriber
re-reads from the unchanged position; chunk-not-found still skips.

* perf(mount): read persisted metadata log chunks directly from volume servers

Set LogFileReaderFn so the filer returns log file references and the mount
reads the chunk data itself, instead of the filer reading, decoding, and
streaming every persisted entry. Keeps a reconnect storm of many mounts
from concentrating hundreds of concurrent log replays in filer memory.

* perf(filer): pre-size chunk stream reader buffer to view size

The chunk size is known up front, so grow the buffer once instead of
letting bytes.Buffer double as the streamed pieces arrive (which
transiently overshoots to ~2x per reader).

* fix(filer): bound concurrent persisted-log replays

Each server-side replay holds an open chunk reader per source filer plus a
readahead buffer, so a reconnect storm of clients that predate the
metadata-chunks offload multiplies into many GB. Gate replays with a
semaphore; abort the acquire when the subscriber's stream is gone so
cancelled clients do not pile up parked goroutines.

Chris LuandGitHub 8776b9d311 feat(filer): object size distribution metric and dashboard panels (#9902)
* feat(filer): record object size distribution histogram

Add SeaweedFS_filer_object_size_bytes, a histogram sampled when an
object is first created in the filer namespace, covering every write
protocol (S3, WebDAV, FUSE mount, direct HTTP). Buckets follow the
1KB/100KB/1MB/100MB/1GB ranges operators use to size collections.
Directories, overwrites, and metadata-only updates are not sampled, so
the bucket counts track the size distribution of distinct objects.

* feat(metrics): add filer object size distribution dashboard panels

Add a write-rate-by-size-range graph and a size-distribution bar gauge,
driven by SeaweedFS_filer_object_size_bytes, to the standalone and Helm
Grafana dashboards. Per-range subtractions are clamped at zero so
transient negative rate() samples do not render below the axis.

Chris LuandGitHub d67fc48fbd fix(filer.sync): guard batched events against nil EventNotification (#9877)
* fix(filer.sync): guard batched events against nil EventNotification

The server folds a backlog into one response: the first event in the
top-level fields, the rest in resp.Events, and the pipelined sender can
drain an idle heartbeat (nil EventNotification) into that tail. Only the
envelope got the freshness-signal guard, so a batched heartbeat reached
AddSyncJob and nil-derefed in IsEmpty while replaying a backlog buffered
during a peer outage.

Route every event, envelope and batched, through one handler that sends
freshness signals (nil heartbeat, empty marker) to OnIdleHeartbeat.

* fix(filer): guard MetaAggregator batched events against nil EventNotification

The peer subscription's envelope is nil-guarded but its batched tail was
not. The aggregator doesn't enable idle heartbeats today, so the server
can't fold a nil EventNotification into the batch yet, but make the two
loops consistent so it can't nil-deref if that changes.

* mysql: keep S3 list order byte-lexicographic regardless of name column collation

ORDER BY name and the name > ? pagination predicate follow the column
collation, so a case-insensitive filemeta.name (e.g. utf8mb3_general_ci)
returns S3 keys out of byte order and breaks clients that merge two sorted
listings.

Detect the live name collation at startup; only when it isn't binary, wrap
the list comparison, prefix, and ORDER BY in BINARY name so order and
pagination stay consistent. Correctly configured utf8mb4_bin tables keep
their indexed range scan unchanged, and the operator gets a warning to
convert the column.

* postgres: keep S3 list order byte-lexicographic regardless of name column collation

ORDER BY name and the name > $n pagination predicate follow the column or
database collation, so a locale-aware filemeta.name (e.g. the en_US.UTF-8
database default) returns S3 keys out of byte order and breaks clients that
merge two sorted listings.

Detect the live name collation at startup; only when it isn't byte-ordered,
wrap the list comparison, prefix, and ORDER BY in COLLATE "C" so order and
pagination stay consistent. A byte-ordered (C/POSIX/C.UTF-8) column keeps its
indexed range scan unchanged, and the operator gets a warning to declare the

Chris LuandGitHub 8c2d9f466f filer: stream persisted log files when serving metadata subscriptions (#9821)
* filer: stream persisted log files when serving metadata subscriptions

readFileEntries buffered every LogEntry of a whole log file into memory
before returning them one by one, making a subscription read O(entries in
one log file) instead of O(one entry). On a filer with large per-entry
metadata, many concurrent SubscribeMetadata streams each loading a full
log file exhausted memory.

Keep a current LogFileIterator and return one entry at a time, advancing
files as each is exhausted. The deleted-volume skip is preserved.

* filer: close the log file iterator on read errors too

A genuine read error returned early without closing the current
LogFileIterator, leaving its ChunkStreamReader alive until GC. Close on
every exit path and propagate only a real error.

* filer: close persisted-log iterators when a subscription stops early

The streaming iterator keeps a log file reader open across calls, so a
subscription that returns before EOF (early stop, cancellation) left the
reader alive until GC. Add idempotent Close on LogFileQueueIterator and
OrderedLogVisitor, and have ReadPersistedLogBuffer wait for the readahead
goroutine and close the visitor on the way out.

* s3: auto-enforce bucket quota read-only both ways

Quota read-only only ever flipped when an admin re-ran
s3.bucket.quota.enforce, so a bucket that went over quota stayed
read-only forever even after usage dropped back under.

Fold enforcement into the per-minute, leader-locked bucket-size loop
the s3 gateway already runs for metrics: it now flips each bucket's
read-only flag to match its quota in both directions, rewriting
filer.conf only when a flag actually changes. The set/clear decision
lives in one shared FilerConf.ApplyBucketQuotaReadOnly helper so the
shell command and the gateway can't drift.

* only manage read-only when a quota is set, never clobber manual locks

Chris LuandGitHub dfd05d14cb refactor(filer): remove the inode->path index and the NFS gateway (#9724)
* fix(filer): derive inodes by hash instead of a snowflake sequencer

Compute the same inode the FUSE mount would: non-hard-linked entries hash path + crtime, hard links hash their shared HardLinkId so every link resolves to one inode. Removes the snowflake inodeSequencer and the SEAWEEDFS_FILER_SNOWFLAKE_ID knob; inodes are now deterministic across filers.

* chore: remove the experimental NFS gateway

The NFS frontend ('weed nfs') was the only consumer of the inode->path index. Remove the weed/server/nfs package, the command and its registration, the integration test harness, and the CI workflow; go mod tidy drops the willscott/go-nfs and go-nfs-client dependencies.

* refactor(filer): drop the inode->path index

With the NFS gateway gone, nothing reads it. A regular file's inode is a pure hash of its path and a hard link's is a hash of its shared HardLinkId -- both derivable on demand -- so the secondary KV index and its write/remove hooks are dead. Removes filer_inode_index.go and the recordInodeIndex hooks from the store wrapper.

upsertQuery is configured, install a sensible default so the
inode-index KvPut does not waste a duplicate-key roundtrip on every
entry write. Uses the VALUES() form so the default works on MariaDB
and MySQL >=5.7; the MySQL 8.0.19 row-alias form is left to explicit
config.

* fix(filer): default enableUpsert=true for sql stores

The default-template fallback only kicks in when enableUpsert=true,
so minimal configs that omit the flag entirely were still exposed.
Default it on for postgres/postgres2/mysql/mysql2; an explicit false
in filer.toml still wins because SetDefault only fills absent keys.

other KV writes landed outside the configured prefix. With a Redis
ACL restricted to the prefix this errored with NOPERM; without the
ACL the keys silently lived in the wrong namespace.

Chris LuandGitHub c9868dcf2f filer/posixlock: remove the unused lock-set serde (#9676)
The codec (Set.Marshal/Unmarshal) and its posix_lock.proto were built to
let the lock set ride in an inode's entry metadata, but the authority is
in-memory and ownership handoff/restart is handled by mounts re-asserting
their held locks over the RPC — neither serializes the set. Nothing calls
the serde outside its own tests, so drop it (codec, proto, generated pb,
Makefile). The in-memory Set/Manager are unchanged.

Chris LuandGitHub f8caaa4464 mount,filer: re-assert POSIX locks via keepalive (ownership migration + restart) (#9668)
* mount: renew POSIX lock leases via keepalive

The mount tracks the inode keys it holds locks on and a background loop
renews its session lease (KEEP_ALIVE) with each key's owner filer every
5s, within the filer's 15s TTL. A live mount is never reaped; a dead one
stops renewing and owners reclaim its locks. Tracking is a superset:
holds are added on grant and dropped only on owner release, so a still
held lock is never under-renewed.

* mount,filer: re-assert held POSIX locks via keepalive

The owner filer holds POSIX advisory locks as in-memory soft state, so a key's
owner change (ring rebalance) or an owner restart lost or stranded them: the new
or restarted owner was blind to existing holders and would double-grant.

Make the keepalive carry the mount's held lock ranges per key. The mount mirrors
its own granted locks (posixOwn), and each tick re-asserts them to the key's
current owner, which rebuilds that session's locks from the assertion — self
-healing after a takeover or restart. The owner arbitrates re-asserted locks
against other sessions so it never double-grants; a lock that lost a migration
race is reported, not forced. A bare keepalive (no ranges) still just renews.

Chris LuandGitHub c97b69f8a4 filer: session lease + reaping for POSIX locks (#9666)
* filer: session lease + reaping for POSIX locks

A mount renews its session lease by keepalive (new KEEP_ALIVE op); the
owner filer records last-seen per session and a background sweeper reaps
the locks of leased sessions that stop renewing — a dead or partitioned
mount. Only sessions that have renewed are leased, so this is inert until
mounts run with -posixLock.

* mount: route POSIX advisory locks to the owner filer (-posixLock) (#9665)

mount: route POSIX advisory locks to the owner filer under -dlm

With -dlm, GetLk/SetLk/SetLkw and the flush/release cleanup paths go to
the inode's owner filer via the PosixLock RPC instead of the local table,
so flock/fcntl are honored across mounts. Advisory locking rides the same
switch as whole-file write coordination — and is therefore off under
writeback cache, which implies single-writer. The mount calls its filer
and relies on filer-side forwarding to reach the owner. Keys are the inode
identity (HardLinkId else path); SetLkw is client-side polling with the
FUSE cancel channel (no server wait queue); a per-mount session id
namespaces owners; a local hint avoids a release RPC on every close.

* mount,filer: bound posix-lock release RPCs and stop the reaper on shutdown

The unlock/release RPCs run off the syscall path (close/flush) and used
context.Background() with no deadline, so a slow or unreachable filer could
hang close() indefinitely; bound them to 5s (they still aren't cancelled by
an interrupt). The lease-reaping sweeper now selects on a stop channel that
FilerServer.Shutdown closes, instead of looping for the process lifetime.

mount's locks reap in O(locks held). Lock state stays in memory like the

Chris LuandGitHub 475ae2b443 filer: serialize the POSIX lock set for entry metadata (phase 2) (#9661)
* filer: POSIX advisory lock set primitive (phase 1)

Pure per-inode conflict/coalesce/range-split logic for fcntl byte-range
and flock whole-file locks, extracted from the mount's PosixLockTable
without its wait queue or inode-map concurrency. Owner identity is
(Sid, Owner) so the same FUSE owner on different mounts never aliases,
and ReleaseSession reaps a dead mount's locks. The owner filer will hold
one Set per inode under the per-path lock; no concurrency control here.

* test: tolerate transient FUSE invisibility in ConcurrentReadWrite

A concurrent truncating overwrite leaves a short-lived dentry/cache window
where the file is momentarily ENOENT to another opener. Retry the reads and
writes a few times before failing, as ConcurrentDirectoryOperations does.

* filer: serialize the POSIX lock set for entry metadata

Versioned fixed-width binary encoding of a Set, so an inode's held locks
can ride in its entry metadata: a lock op materializes the Set from the
blob, applies under the per-path lock, and writes it back. Empty set
encodes to nil so a lock-free inode carries no blob.

* filer: encode the POSIX lock set as protobuf

Replace the hand-rolled fixed-width codec with a LockSetProto message, so the
metadata blob can gain fields without a format-version migration. proto.Unmarshal
already rejects a malformed blob, so the explicit version and length checks go
away. Marshal now returns an error to match.

Chris LuandGitHub 83195fc111 filer: reuse the caller's fetched entry in CreateEntry (#9645)
CreateEntry starts with a FindEntry to load the current entry. A conditional
CreateEntry already fetched that entry to evaluate the precondition under the
per-path lock, so the create repeated the lookup.

Add an existing *Entry parameter: when non-nil it is used as the current entry
and the internal lookup is skipped; nil keeps the lookup. The gRPC CreateEntry
handler passes the entry it fetched for the precondition, removing the redundant
read while the lock is held. All other callers pass nil.

Chris LuandGitHub 3f6410fdc3 fix(redis3): prevent filer crash from inconsistent skiplist ends (#9602)
* fix(redis3): prevent filer crash from inconsistent skiplist ends

DeleteByKey updated the two ends asymmetrically: the start side decided
whether to clear StartLevels[index] by comparing a cached reference key,
while the end side cleared EndLevels[index] structurally. The redis3
ItemList re-keys a node while keeping its id, so that cached key drifts.
When such a node was the only one at a level and got deleted, the stale
key comparison left StartLevels dangling while EndLevels was cleared to
nil. The next InsertByKey then dereferenced a nil EndLevels[0] and took
down the whole filer during a rename or delete.

Match the deleted node by its unique id so both ends stay consistent,
and guard each end in InsertByKey so an already-corrupted skiplist
persisted in Redis self-heals instead of crashing on load.

* fix(redis3): propagate errors from WriteName node split

The case 2.3 split path returned nil instead of the error in seven
branches. Because the split runs a multi-step sequence (DeleteByKey on
the skiplist, ItemAdd, redis range-delete, ItemAdd), a swallowed failure
let WriteName report success while the skiplist was half-updated, which
the caller then persisted - silently corrupting the directory listing
and setting up the very inconsistent-ends state that crashes the filer.

Chris LuandGitHub a17dca7009 fix(filer): don't disable the SQL idle connection pool when unconfigured (#9591)
* fix(filer): don't disable the SQL idle connection pool when unconfigured

The mysql/mysql2/postgres stores called SetMaxIdleConns(maxIdle)
unconditionally, so an unset connection_max_idle (0) actively kept zero
idle connections - every query opened and closed a fresh connection
instead of reusing the pool.

Only apply the value when it's set; otherwise leave database/sql's
default idle pool of 2 in place.

* comments: shorten idle-pool note

* fix(filer): default the SQL idle pool via config, keep explicit 0 honored

Apply the idle-pool default at the config layer with SetDefault instead of
guarding the SetMaxIdleConns call. An absent connection_max_idle now reads
back as 2 (pool stays on), while an explicit 0 flows through to
SetMaxIdleConns(0) so operators can still disable idle pooling on purpose.

4476cb282b feat(filer): add atime to FuseAttributes + TouchAccessTime RPC (#9556)
* feat(filer): add atime field and TouchAccessTime RPC to filer proto

Introduce POSIX-style access-time tracking on the filer:
- FuseAttributes gains atime (field 22) and atime_ns (field 23).
- New TouchAccessTime RPC (and Touch{Access,Time}{Request,Response})
  lets read paths bump atime without going through UpdateEntry's
  chunk-rewrite/EqualEntry short-circuit.

Additive proto changes only; zero atime is treated as unset and
existing clients are unaffected. Java client proto is kept in lock
step.

Co-authored-by: Cursor <cursoragent@cursor.com>

* feat(filer): wire Atime through Attr codec with mtime fallback

Add Attr.Atime and round-trip it through EntryAttributeToPb /
EntryAttributeToExistingPb / PbToEntryAttribute. A zero proto atime
decodes as Mtime, so legacy entries report a sensible value and
freshly-created/updated entries default Atime to Mtime when callers
do not set it explicitly.

CreateEntry and UpdateEntry stamp Atime = Mtime (or Crtime) when it
is zero. TouchAccessTime later bypasses this path to write atime
alone via Store.UpdateEntry.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(filer): preserve atime in first epoch second on decode

The Atime decode branch previously treated any attr.Atime == 0 as
unset and overwrote it with Mtime, which drops valid timestamps in
the first second of the unix epoch where attr.Atime is 0 but
attr.AtimeNs > 0. Check both fields so we only fall back to Mtime
when both are zero.

Chris LuandGitHub 10cc06333b cluster: restrict Ping RPC to known peers of the requested type (#9445)
Ping previously dialled whatever host:port the caller asked for. Gate
each server's Ping handler on cluster membership: masters check the
topology, registered cluster nodes, and configured master peers; volume
servers only accept their seed/current masters; filers accept tracked
peer filers, the master-learned volume server set, and configured
masters.

Use address-indexed peer lookups to keep Ping target validation O(1):
- topology maintains a pb.ServerAddress -> *DataNode index alongside
  the dc/rack/node tree, kept in sync from doLinkChildNode and
  UnlinkChildNode plus the ip/port-rewrite branch in
  GetOrCreateDataNode. GetTopology now returns nil on a detached
  subtree instead of panicking, so the linkage hooks can no-op safely.
- vid_map tracks a refcount per volume-server address so
  hasVolumeServer answers without scanning every vid location. The
  add path skips empty-address entries the same way the delete path
  already does, so a zero-value Location cannot leak a permanent
  serverRefCount[""] bucket.
- masters reuse a cached master-address set from MasterClient instead
  of walking the configured peer slice on every request.
- volume servers compare against a pre-built seed-master set and
  protect currentMaster reads/writes with an RWMutex, fixing the
  data race with the heartbeat goroutine. The seed slice is copied
  on construction so external mutation cannot desync it from the
  frozen lookup set.
- cluster.check drops the direct volume-to-volume sweep; volume
  servers no longer carry a peer-volume list, and the note next to
  the dropped probe is reworded to make clear that direct
  volume-to-volume reachability is intentionally not validated by
  this command.

Update the volume-server integration tests that drove Ping through the
new admission gate: success-path coverage now targets the master peer
(the only type a volume server tracks), and the unknown/unreachable
path asserts the InvalidArgument the gate now returns instead of the
old downstream dial error.

Mirror the same admission gate in the Rust volume server crate: a
seed-master HashSet built once at startup plus a tokio RwLock over the
heartbeat-tracked current master, both consulted in is_known_ping_target
on every Ping, with InvalidArgument returned for any target that isn't
a recognised master.

Chris LuandGitHub 35e3fe89bc feat(s3/lifecycle): filer-backed cursor Persister + drop BlockerStore (#9358)
* feat(s3/lifecycle): filer-backed cursor Persister

FilerPersister persists per-shard cursor maps as JSON to
/etc/s3/lifecycle/cursors/shard-NN.json via filer.SaveInsideFiler.
One file per shard keeps Save atomic — the filer writes the entry
in a single mutation, so a crash mid-write doesn't leak partial
state. Pipeline.Run loads on start; the periodic checkpoint and
graceful-shutdown save go through this implementation.

A small FilerStore interface wraps the SeaweedFilerClient surface
the persister needs, so tests inject an in-memory fake instead of
mocking the full gRPC client.

* refactor(s3/lifecycle): drop BlockerStore — durable cursor IS the block

A frozen cursor doesn't advance, so the durable cursor (FilerPersister)
encodes the blocked state on its own. On worker restart the reader
re-encounters the poison event at MinTsNs, the dispatcher walks the
same retry budget to BLOCKED, and the cursor freezes at the same
EventTs. Other in-flight events between freeze tsNs and prior cursor
positions self-resolve via NOOP_RESOLVED (STALE_IDENTITY) since the
underlying objects were already deleted on the prior pass.

Removed:
  - BlockerStore interface + InMemoryBlockerStore + BlockerRecord
  - Dispatcher.Blockers + Dispatcher.ReplayBlockers
  - the BlockerStore.Put call in handleBlocked
  - Pipeline.Blockers field + the ReplayBlockers call on startup

Added a TestDispatchRestartReFreezesNaturally that pins the
self-recovery property: a fresh Dispatcher with a fresh Cursor, fed
the same poison event, reaches the same frozen state at the same
EventTs without any durable blocker store.

Operator visibility: a cursor whose MinTsNs hasn't advanced is the
signal — surfaced via the durable cursor file.

* refactor(filer): SaveInsideFiler accepts ctx

ReadInsideFiler already takes ctx; SaveInsideFiler used context.Background()
internally and silently dropped the caller's ctx. Symmetric API now;
cancellation/deadlines propagate through LookupEntry / CreateEntry /
UpdateEntry. Mechanical update of all callers — most pass
context.Background() since the existing call sites have no ctx in scope.

* fix(s3/lifecycle): deterministic order in cursor save

Iterating Go maps yields random order, so json.Encode produced a different
byte sequence on each save even when the state hadn't changed. Sort
entries by (Bucket, ActionKind, RuleHash) before encoding so the on-disk
file diffs cleanly. New test pins byte-identical output across two saves
of the same map.

* fix(s3/lifecycle): log reason when freezing cursor in handleBlocked

handleBlocked dropped the reason via _ = reason with a comment claiming
the caller logged it; none of the three callers do. A frozen cursor is
the only surface where the operator finds out something stuck, so the
reason has to land somewhere. glog.Warningf with shard, key, eventTs,
and the original reason — same shape the rest of the package uses.

Chris LuandGitHub 0fa0a56a5a filer(mysql): TLS hostname/SNI knobs + MariaDB upsert documentation (#9260)
* refactor(filer/mysql): set tls.Config per-instance via Connector instead of global registry

Replace the use of `mysql.RegisterTLSConfig("mysql-tls", ...)` and the
`&tls=mysql-tls` DSN suffix with a per-instance setup that assigns the
`*tls.Config` directly to `mysql.Config.TLS` and opens the database via
`mysql.NewConnector` + `sql.OpenDB`.

The driver's TLS-config registry is process-wide; if a second `MysqlStore`
were ever initialized with different TLS settings (e.g., a filer plus a
separately configured store) the second registration would silently
overwrite the first. The connector pattern keeps the TLS configuration
attached to the connector and avoids that global side effect.

Behavior is otherwise unchanged: TLS is enabled when `enable_tls=true`,
the same `ca_crt`/`client_crt`/`client_key` knobs are honored, and the
TLS minimum version remains 1.2.

* filer(mysql): use system root CAs when ca_crt is empty

Previously, enabling `enable_tls=true` without setting `ca_crt` returned an
unhelpful empty-path read error. Many managed MySQL/MariaDB providers serve
certificates that chain to a public CA already in the host's trust store, so
requiring an explicit CA bundle adds friction with no security benefit.

Leave `RootCAs` unset when `ca_crt` is empty so Go's `tls.Config` falls back
to the system trust store, matching the standard behavior of `mysql --ssl`.
Existing setups with `ca_crt` configured are unaffected.

Also wraps the CA read/parse errors with the file path for easier diagnosis.

* filer(mysql): fail loudly when client_crt / client_key are unreadable

The previous implementation called `tls.LoadX509KeyPair` and silently
discarded any error, falling back to a non-mTLS connection. A typo or
permissions problem in `client_crt` / `client_key` therefore appeared as a
confusing server-side handshake error rather than as a config error,
because the server was expecting a client cert that the filer never sent.

Treat the keypair as required when either path is set, and surface the
underlying load error with both filenames so the misconfiguration is
obvious. The default (both paths empty) is unchanged: no client cert is
sent.

* filer(mysql): add tls_insecure_skip_verify and tls_server_name knobs

When the filer connects to a MySQL/MariaDB cluster whose server
certificate's SAN does not match the connection address (common with
internal load balancers, IP-only connection strings, or self-signed
cluster certs), the TLS handshake fails with `x509: certificate is valid
for X, not Y`. There was previously no way to fix this short of reissuing
the cert.

Expose two new optional knobs on `[mysql]`:

- `tls_server_name` overrides the SNI / cert hostname used for
  verification — the standard fix when the cert SAN is correct but the
  connection address is not.
- `tls_insecure_skip_verify` disables verification entirely as an escape
  hatch for testing or for clusters with no usable SAN.

Both default to off, so existing configurations continue to verify the
server certificate against the connection address as before.

* docs(scaffold/filer.toml): document mysql TLS knobs and MariaDB upsert override

- Document the new `tls_insecure_skip_verify` and `tls_server_name` options.
- Update the `ca_crt` comment to reflect that it is optional and that the
  system trust store is used when the path is empty (matches the runtime
  behavior in mysql_store.go).
- Reword the client cert comments to make the mTLS pairing requirement
  explicit (both `client_crt` and `client_key` must be set together).
- Add a commented-out MariaDB / MySQL 5.7 alternative for `upsertQuery`,
  noting that the default (`AS new` row alias) requires MySQL 8.0.19+.

* filer(mysql): drop redundant blank import of go-sql-driver/mysql

The package was imported twice: once with the `mysql` alias (used for
`mysql.MySQLError`, `mysql.Config`, `mysql.NewConnector`, etc.) and once
as `_` to register the driver. The named import already triggers
`init()` and registers the driver, so the blank import is dead weight.

Chris LuandGitHub c934b5dab6 fix(credential/postgres,s3api/iam): rename safety + pgxutil follow-ups to #9226 (#9230)
* refactor(util): extract pgx OpenDB + DSN builder into shared pgxutil

The postgres filer store had OpenPGXDB plus duplicated key=value DSN
assembly across postgres/ and postgres2/. Move the connection helper to
weed/util/pgxutil and add BuildDSN so the credential postgres store can
land on the same code path.

filer/postgres/pgx_conn.go keeps OpenPGXDB as a thin alias so postgres2
keeps building unchanged.

* refactor(credential/postgres): use shared pgxutil for connection setup

Replace the bespoke fmt.Sprintf DSN + sql.Open("pgx", ...) path with
pgxutil.BuildDSN + pgxutil.OpenDB so the credential store mirrors the
postgres filer store. This also drops the leaky RegisterConnConfig-style
init in favor of stdlib.OpenDB(*config), which doesn't accumulate
entries in the global pgx config map.

Adds parity knobs the filer store already exposes: sslcrl, and
configurable connection_max_idle / connection_max_open /
connection_max_lifetime_seconds (with the previous hardcoded 25/5/5min
as defaults). Also moves the jsonbParam helper here so other store
files can reuse it. (Helper is also referenced by postgres_identity.go,
which is migrated to it in the next commit.)

* refactor(credential/postgres): use jsonbParam helper across all writers

Consolidate JSONB write handling on the new pgxutil-adjacent helper
jsonbParam(b []byte) interface{}, which returns nil (driver writes SQL
NULL) when the marshaled JSON is empty and string(b) otherwise.

postgres_identity.go: replace the inline 'var fooParam any' /
'fooParam = string(b)' pattern with the helper. Same in CreateUser
and UpdateUser.

postgres_inline_policy.go, postgres_policy.go, postgres_service_account.go,
postgres_group.go: every JSONB writer was still passing []byte. Under
pgx simple_protocol (pgbouncer_compatible=true), []byte is encoded as
bytea and Postgres rejects that against a JSONB column with "invalid
input syntax for type json". Route them through jsonbParam too.

* fix(credential/postgres): rework SaveConfiguration to handle rename + UNIQUE access keys

The IAM rename path (s3api UpdateUser) renames an identity in place
and keeps its access keys. With the previous flow — upsert each user,
then per-user delete-and-insert credentials, then prune absent users —
the renamed user's access keys were still owned by the old row when
the INSERT for the new name ran, tripping credentials.access_key's
global UNIQUE constraint and failing every rename of a user with
credentials.

Reorder the SaveConfiguration body so the prune step runs BEFORE the
credential replace. CASCADE on the old user releases its access keys
in the same transaction, and the new name can then claim them.

While here:
- Replace the per-user loop DELETE FROM users WHERE username = $1 with
  a single DELETE ... WHERE username = ANY($1), one round trip instead
  of N inside the transaction.
- Surface inline-policy CASCADE losses: count user_inline_policies for
  the prune set and emit a Warningf when the count is non-zero so
  rename-driven drops are visible in operator logs (the structural
  fix for renames lives at the IAM layer in a follow-up commit).
- Two-pass credential replace: clear credentials for every user we are
  about to rewrite first, then insert, so an access key can be moved
  between two users in the same SaveConfiguration call.
- credErr := credRows.Err() before credRows.Close() in
  LoadConfiguration — Err() is documented as safe after Close, but
  the leading-capture pattern matches the rest of the file.

* fix(s3api/iam): preserve inline policies when renaming a user

EmbeddedIamApi.UpdateUser renames an identity in place and the caller
persists via SaveConfiguration, which prunes the old username and
CASCADE-drops its rows from user_inline_policies. GetUserPolicy and
ListUserPolicies then return nothing under the new name even though
the API reported success — silent data loss.

Before flipping sourceIdent.Name, list the user's stored inline
policies and re-attach each one under the new name. The subsequent
SaveConfiguration prune still CASCADE-removes the old-name rows; only
the duplicates we just wrote under the new name survive. Adds a
regression test that puts a policy on the old name, renames, and
asserts the policy is readable under the new name.

* perf(credential/postgres): batch the credential clear in SaveConfiguration

The two-pass credential replace was clearing each incoming user's
credentials with its own DELETE statement — N round-trips inside the
transaction. Match the pattern already used for the user prune and
issue a single DELETE FROM credentials WHERE username = ANY($1)
instead.

* refactor(s3api/iam): plumb context through UpdateUser

UpdateUser was synthesizing a fresh context.Background() inside the
inline-policy migration block, which discards the request deadline,
cancellation, and tracing carried by the caller. Add ctx as the first
parameter and pass r.Context() in via the ExecuteAction dispatcher,
mirroring the signature already used by CreatePolicy /
AttachUserPolicy / DetachUserPolicy.

* fix(util/pgxutil): quote DSN values per libpq rules

BuildDSN was concatenating values directly, so any password / cert path
/ database name with a space, single quote, or backslash produced a
malformed connection string and pgx.ParseConfig either errored or
mis-parsed the remainder. Critical now that the helper is shared with
the credential store: mTLS deployments routinely sourcing passwords or
secret-mounted cert paths from a vault are exactly the case where
spaces and quotes show up.

Add quoteDSNValue: empty values and values containing whitespace, `'`,
or `\` are wrapped in single quotes with `'` and `\` escaped per
PostgreSQL libpq rules; plain alphanumeric values pass through
unchanged. Apply it to every variable field in BuildDSN.

Adds a test that round-trips a password containing spaces, quotes and
backslashes through pgx.ParseConfig and confirms the parsed Config
matches the input.

* fix(credential,s3api/iam): atomic UserRenamer to avoid FK violation on rename

The previous IAM rename path called PutUserInlinePolicy(newName, ...)
before SaveConfiguration created the new users row. user_inline_policies
has a non-deferrable FOREIGN KEY (username) REFERENCES users(username),
which Postgres validates at statement time, so every rename of a user
that owned at least one inline policy failed with an FK violation. The
existing memory-store regression test missed it because the memory
backend has no FK enforcement.

Add an optional credential.UserRenamer interface plus a
CredentialManager.RenameUser thin shim that returns (supported, err).

Implement it on PostgresStore as an atomic in-transaction migration:
INSERT the new users row by SELECT-copying from the old, UPDATE
credentials.username and user_inline_policies.username to the new
name (FK satisfied because both rows now exist), then DELETE the old
row. ErrUserNotFound / ErrUserAlreadyExists are surfaced cleanly.

Implement it on MemoryStore by re-binding store.users / store.accessKeys
/ store.inlinePolicies under the new name. Also fixes a small leak in
DeleteUser, which was forgetting to drop the user's inline-policy
bucket.

EmbeddedIamApi.UpdateUser now calls RenameUser first; if the store
implements the interface, that's the whole migration. If it doesn't
(stores without FK enforcement), fall back to the previous
list / get / put copy.

Adds a focused test for MemoryStore.RenameUser that asserts the
identity, the access-key index, and the inline policies all land
under the new name.

* proto: define MountRegister/MountList and MountPeer service

Adds the wire types for peer chunk sharing between weed mount clients:

* filer.proto: MountRegister / MountList RPCs so each mount can heartbeat
  its peer-serve address into a filer-hosted registry, and refresh the
  list of peers. Tiny payload; the filer stores only O(fleet_size) state.

* mount_peer.proto (new): ChunkAnnounce / ChunkLookup RPCs for the
  mount-to-mount chunk directory. Each fid's directory entry lives on
  an HRW-assigned mount; announces and lookups route to that mount.

No behavior yet — later PRs wire the RPCs into the filer and mount.
See design-weed-mount-peer-chunk-sharing.md for the full design.

* filer: add mount-server registry behind -peer.registry.enable

Implements tier 1 of the peer chunk sharing design: an in-memory registry
of live weed mount servers, keyed by peer address, refreshed by
MountRegister heartbeats and served by MountList.

* weed/filer/peer_registry.go: thread-safe map with TTL eviction; lazy
  sweep on List plus a background sweeper goroutine for bounded memory.

* weed/server/filer_grpc_server_peer.go: MountRegister / MountList RPC
  handlers. When -peer.registry.enable is false (the default), both RPCs
  are silent no-ops so probing older filers is harmless.

* -peer.registry.enable flag on weed filer; FilerOption.PeerRegistryEnabled
  wires it through.

Phase 1 is single-filer (no cross-filer replication of the registry);
mounts that fail over to another filer will re-register on the next
heartbeat, so the registry self-heals within one TTL cycle.

Part of the peer-chunk-sharing design; no behavior change at runtime
until a later PR enables the flag on both filer and mount.

* filer: nil-safe peerRegistryEnable + registry hardening

Addresses review feedback on PR #9131.

* Fix: nil pointer deref in the mini cluster. FilerOptions instances
  constructed outside weed/command/filer.go (e.g. miniFilerOptions in
  mini.go) do not populate peerRegistryEnable, so dereferencing the
  pointer panics at Filer startup. Use the same
  `nil && deref` idiom already used for distributedLock / writebackCache.

* Hardening (gemini review): registry now enforces three invariants:
  - empty peer_addr is silently rejected (no client-controlled sentinel
    mass-inserts)
  - TTL is capped at 1 hour so a runaway client cannot pin entries
  - new-entry count is capped at 10000 to bound memory; renewals of
    existing entries are always honored, so a full registry still
    heartbeats its existing members correctly

Covered by new unit tests.

* filer: rename -peer.registry.enable flag to -mount.p2p

Per review feedback: the old name "peer.registry.enable" leaked
the implementation ("registry") into the CLI surface. "mount.p2p"
is shorter and describes what it actually controls — whether this
filer participates in mount-to-mount peer chunk sharing.

Flag renames (all three keep default=true, idle cost is near-zero):
  -peer.registry.enable        ->  -mount.p2p         (weed filer)
  -filer.peer.registry.enable  ->  -filer.mount.p2p   (weed mini, weed server)

Internal variable names (mountPeerRegistryEnable, MountPeerRegistry)
keep their longer form — they describe the component, not the knob.

* filer: MountList returns DataCenter + List uses RLock

Two review follow-ups on the mount peer registry:

* weed/server/filer_grpc_server_mount_peer.go: MountList was dropping
  the DataCenter on the wire. The whole point of carrying DC separately
  from Rack is letting the mount-side fetcher re-rank peers by the
  two-level locality hierarchy (same-rack > same-DC > cross-DC); without
  DC in the response every remote peer collapsed to "unknown locality."

* weed/filer/mount_peer_registry.go: List() was taking a write lock so
  it could lazy-delete expired entries inline. But MountList is a
  read-heavy RPC hit on every mount's 30 s refresh loop, and Sweep is
  already wired as the sole reclamation path (same pattern as the
  mount-side PeerDirectory). Switch List to RLock + filter, let Sweep
  do the map mutation, so concurrent MountList callers don't serialize
  on each other.

Test updated to reflect the new contract (List no longer mutates the
map; Sweep is what drops expired entries).

Chris LuandGitHub 00a2e22478 fix(mount): remove fid pool to stop master over-allocating volumes (#9111)
* fix(mount): remove fid pool to stop master over-allocating volumes

The writeback-cache fid pool pre-allocated file IDs with
ExpectedDataSize = ChunkSizeLimit (typically 8+ MB). The master's
PickForWrite charges count * expectedDataSize against the volume's
effectiveSize, so a full pool refill could charge hundreds of MB
against a single volume before any bytes were actually written.
That tripped RecordAssign's hard-limit path and eagerly removed
volumes from writable, causing the master to grow new volumes
even when the real data being written was tiny.

Drop the pool entirely. Every chunk upload goes through
UploadWithRetry -> AssignVolume with no ExpectedDataSize hint,
letting the master fall back to the 1 MB default estimate. The
mount->filer grpc connection is already cached in pb.WithGrpcClient
(non-streaming mode), so per-chunk AssignVolume is a unary RPC
over an existing HTTP/2 stream, not a full dial. Path-based
filer.conf storage rules now apply to mount chunk assigns again,
which the pool had to skip.

Also remove the now-unused operation.UploadWithAssignFunc and its
AssignFunc type.

* fix(upload): populate ExpectedDataSize from actual chunk bytes

UploadWithRetry already buffers the full chunk into `data` before
calling AssignVolume, so the real size is known. Previously the
assign request went out with ExpectedDataSize=0, making the master
fall back to the 1 MB DefaultNeedleSizeEstimate per fid — same
over-reservation symptom the pool had, just smaller per call.

Stamp ExpectedDataSize = len(data) before the assign RPC when the
caller hasn't already set it. This covers mount chunk uploads,
filer_copy, filersink, mq/logstore, broker_write, gateway_upload,
and nfs — all the UploadWithRetry paths.

* fix(assign): pass real ExpectedDataSize at every assign call site

After removing the mount fid pool, per-chunk AssignVolume calls went
out with ExpectedDataSize=0, making the master fall back to its 1 MB
DefaultNeedleSizeEstimate. That's still an over-estimate for small
writes. Thread the real payload size through every remaining assign
site so RecordAssign charges effectiveSize accurately and stops
prematurely marking volumes full.

- filer: assignNewFileInfo now takes expectedDataSize and stamps it
  on both primary and alternate VolumeAssignRequests. Callers pass:
  - SSE data-to-chunk: len(data)
  - copy manifest save: len(data)
  - streamCopyChunk: srcChunk.Size
  - TUS sub-chunk: bytes read
  - saveAsChunk (autochunk/manifestize): 0 (small, size unknown
    until the reader is drained; master uses 1 MB default)
- filer gRPC remote fetch-and-write: ExpectedDataSize = chunkSize
  after the adaptive chunkSize is computed.
- ChunkedUploadOption.AssignFunc gains an expectedDataSize parameter;
  upload_chunked.go passes the buffered dataSize at the call site.
  S3 PUT assignFunc stamps it on the AssignVolumeRequest.
- S3 copy: assignNewVolume / prepareChunkCopy take expectedDataSize;
  all seven call sites pass the source chunk's Size.
- operation.SubmitFiles / FilePart.Upload: derive per-fid size from
  FileSize (average for batched requests, real per-chunk size for
  sequential chunk assigns).
- benchmark: pass fileSize.
- filer append-to-file: pass len(data).

* fix(assign): thread size through SaveDataAsChunkFunctionType

The saveAsChunk path (autochunk, filer_copy, webdav, mount) ran
AssignVolume before the reader was drained, so it had to pass
ExpectedDataSize=0 and fall back to the master's 1 MB default.

Add an expectedDataSize parameter to SaveDataAsChunkFunctionType.
- mergeIntoManifest already has the serialized manifest bytes, so
  it passes uint64(len(data)) directly.
- Mount's saveDataAsChunk ignores the parameter because it uses
  UploadWithRetry, which already stamps len(data) on the assign
  after reading the payload.
- webdav and filer_copy saveDataAsChunk follow the same UploadWithRetry
  path and also ignore the hint.
- Filer's saveAsChunk (used for manifestize) plumbs the value to
  assignNewFileInfo so manifest-chunk assigns get a real size.

Callers of saveFunc-as-value (weedfs_file_sync, dirty_pages_chunked)
pass the chunk size they're about to upload.

Chris LuandGitHub 886d50a6a5 feat(mount): singleflight dedup for concurrent chunk reads (#9100)
* feat(mount): add singleflight deduplication for concurrent chunk reads

When multiple FUSE readers request the same uncached chunk concurrently,
only one network fetch is performed. Other readers wait and share the
downloaded data, reducing redundant volume server traffic under parallel
read workloads.

* fix(util): make singleflight panic-safe with defer cleanup

If the provided function panics, the WaitGroup and map entry are now
cleaned up via defer, preventing other waiters from hanging forever.

* fix(filer): remove singleflight from reader_cache to fix buffer ownership

The singleflight wrapper around chunk fetches returned the same []byte
buffer to concurrent callers. Since each SingleChunkCacher owns and
frees its data buffer in destroy(), sharing the same slice would cause
a use-after-free or double-free with the mem allocator.

The downloaders map already deduplicates in-flight downloads for the
same fileId, so the singleflight was redundant at this layer. The
SingleFlightGroup utility is retained for use elsewhere.

Chris LuandGitHub 213b6c3107 fix(mount): count manifest sizes in merge condition to prevent accumulation (#9101)
* fix(mount): count manifest sizes in merge condition to prevent manifest accumulation

shouldMergeChunks only counted non-manifest chunk sizes toward the bloat
threshold, so overlapping manifests accumulated undetected across flush
cycles.

During sustained random writes (e.g. fio), each metadata flush compacts
non-manifest chunks and may group them into a new manifest via
MaybeManifestize, while carrying forward all existing manifests. Since
the merge condition only checked non-manifest totals against 2x file
size, the growing pile of redundant manifests never triggered a merge.

In a real workload: 4 GB file, 25 manifests each covering ~4 GB
(107 GB manifest data on volume servers), but shouldMergeChunks saw only
4.2 GB of non-manifest chunks vs the 8.6 GB threshold -- no merge.

Fix: include manifest coverage sizes in totalChunkSize. This correctly
detects the 111 GB total vs 8.6 GB threshold and triggers the merge,
which re-reads the file as clean chunks and lets the filer's MinusChunks
(which resolves manifests) garbage-collect all redundant sub-chunks.

* test(mount,filer): add manifest chunk correctness tests

Filer-level tests (filechunk_manifest_test.go):
- TestManifestRoundTripPreservesChunks: create -> serialize -> deserialize
  preserves fileId, offset, size, and timestamp for all sub-chunks
- TestCompactResolvedOverlappingManifests: two manifests covering the same
  range, older sub-chunks correctly identified as garbage after compaction
- TestDoMinusChunksWithResolvedManifests: old manifest sub-chunks detected
  as garbage when compared against new clean chunks (mirrors filer cleanup)
- TestManifestizeSmallBatchWithRemainder: batch=3 with 7 chunks produces
  2 manifests + 1 remainder, all data recoverable after resolve
- TestCompactMultipleOverlappingManifestGenerations: 5 generations of
  full-file manifests, compaction keeps only the newest generation
- TestManifestBloatDetection: with N overlapping manifests, merge triggers
  at N >= 2 (stored > 2x file size)

Mount-level test (weedfs_file_sync_test.go):
- TestFlushCycleManifestAccumulation: simulates the flushMetadataToFiler
  pipeline over multiple cycles with a small manifest batch (5 chunks).
  Verifies merge triggers at cycle 2 when accumulated manifests exceed
  the 2x threshold. Uses SeparateManifestChunks + CompactFileChunks +
  shouldMergeChunks to mirror the real code path.

Chris LuandGitHub 979c54f693 fix(wdclient,volume): compare master leader with ServerAddress.Equals (#9089)
* fix(wdclient,volume): compare master leader with ServerAddress.Equals

Raft leader is advertised as host:httpPort.grpcPort, but clients dial
host:httpPort. Raw string comparison against VolumeLocation.Leader /
HeartbeatResponse.Leader therefore never matches, causing the
masterclient and the volume server heartbeat loop to continuously
"redirect" to the already-connected master, tearing down the stream
and reconnecting.

Use ServerAddress.Equals, which normalizes the grpc-port suffix.

* fix(filer,mq): compare ServerAddress via Equals in two more sites

filer bootstrap skip (MaybeBootstrapFromOnePeer) and the broker's local
partition assignment check both compared a wire-supplied address string
against the local self ServerAddress with raw string equality. Both are
vulnerable to the same plain-vs-host:port.grpcPort mismatch as the
masterclient/volume heartbeat sites: filer would bootstrap from itself,
and the broker would fail to claim a partition it was actually assigned.
Route both through ServerAddress.Equals.

* fix(master,shell): more ServerAddress comparisons via Equals

- raft_server_handlers.go HealthzHandler: s.serverAddr == leader would
  skip the child-lock check on the real leader when the two carry
  different plain/grpc-suffix forms, returning 200 OK instead of 423.
- master_server.go SetRaftServer leader-change callback: the
  Leader() == Name() guard for ensureTopologyId could disagree with
  topology.IsLeader() (which already uses Equals), so leader-only
  initialization could be skipped after an election.
- command_volume_merge.go isReplicaServer: the -target guard compared
  user-supplied host:port against NewServerAddressFromDataNode(...) with
  ==, letting an existing replica slip through when topology carries
  the embedded gRPC port.

All routed through pb.ServerAddress.Equals.

* fix(mq,cluster): more ServerAddress comparisons via Equals

- broker_grpc_lookup.go GetTopicPublishers/GetTopicSubscribers: the
  partition ownership check gated listing on raw
  LeaderBroker == BrokerAddress().String(), so listings silently omitted
  partitions hosted locally when the assignment carried the other
  host:port / host:port.grpcPort form.
- lock_client.go: LockHostMovedTo comparison and the seedFiler fallback
  guard both used raw string equality against configured filer
  addresses (which may be plain host:port while LockHostMovedTo comes
  back suffixed), causing spurious host-change churn and blocking the
  seed-filer fallback.

* fix(mq): more ServerAddress comparisons via Equals

- pub_balancer/allocate.go EnsureAssignmentsToActiveBrokers: direct
  activeBrokers.Get() lookup missed brokers when a persisted assignment
  carried a different address encoding than the registered broker key,
  triggering a bogus reassignment on every read/write cycle. Added a
  findActiveBroker helper that falls back to an Equals-based scan and
  canonicalizes the assignment in place so later writes are stable.
- broker_grpc_lookup.go isLockOwner: used raw string equality between
  LockOwner() and BrokerAddress().String(), so a lock owner could fail
  to recognize itself and proxy local lookup/config/admin RPCs away.
- pub_client/scheduler.go onEachAssignments: reused publisher jobs only
  on exact LeaderBroker match, so an encoding flip in lookup results
  tore down and recreated a stream to the same broker.

Chris LuandGitHub 08d9193fe1 [nfs] Add NFS (#9067)
* add filer inode foundation for nfs

* nfs command skeleton

* add filer inode index foundation for nfs

* make nfs inode index hardlink aware

* add nfs filehandle and inode lookup plumbing

* add read-only nfs frontend foundation

* add nfs namespace mutation support

* add chunk-backed nfs write path

* add nfs protocol integration tests

* add stale handle nfs coverage

* complete nfs hardlink and failover coverage

* add nfs export access controls

* add nfs metadata cache invalidation

* fix nfs chunk read lookup routing

* fix nfs review findings and rename regression

* address pr 9067 review comments

- filer_inode: fail fast if the snowflake sequencer cannot start, and let
  operators override the 10-bit node id via SEAWEEDFS_FILER_SNOWFLAKE_ID
  to avoid multi-filer collisions
- filer_inode: drop the redundant retry loop in nextInode
- filerstore_wrapper: treat inode-index writes/removals as best-effort so
  a primary store success no longer surfaces as an operation failure
- filer_grpc_server_rename: defer overwritten-target chunk deletion until
  after CommitTransaction so a rolled-back rename does not strand live
  metadata pointing at freshly deleted chunks
- command/nfs: default ip.bind to loopback and require an explicit
  filer.path, so the experimental server does not expose the entire
  filer namespace on first run
- nfs integration_test: document why LinkArgs matches go-nfs's on-the-wire
  layout rather than RFC 1813 LINK3args

* mount: pre-allocate inode in Mkdir and Symlink

Mkdir and Symlink used to send filer_pb.CreateEntryRequest with
Attributes.Inode = 0. After PR 9067, the filer's CreateEntry now assigns
its own inode in that case, so the filer-side entry ends up with a
different inode than the one the mount allocates via inodeToPath.Lookup
and returns to the kernel. Once applyLocalMetadataEvent stores the
filer's entry in the meta cache, subsequent GetAttr calls read the
cached entry and hit the setAttrByPbEntry override at line 197 of
weedfs_attr.go, returning the filer-assigned inode instead of the
mount's local one. pjdfstest tests/rename/00.t (subtests 81/87/91)
caught this — it lstat'd a freshly-created directory/symlink, renamed
it, lstat'd again, and saw a different inode the second time.

createRegularFile already pre-allocates via inodeToPath.AllocateInode
and stamps it into the create request. Do the same thing in Mkdir and
Symlink so both sides agree on the object identity from the very first
request, and so GetAttr's cache path returns the same value as Mkdir /
Symlink's initial response.

* sequence: mask snowflake node id on int→uint32 conversion

CodeQL flagged the unchecked uint32(snowflakeId) cast in
NewSnowflakeSequencer as a potential truncation bug when snowflakeId is
sourced from user input (e.g. via SEAWEEDFS_FILER_SNOWFLAKE_ID). Mask
to the 10 bits the snowflake library actually uses so any caller-
supplied int is safely clamped into range.

* add test/nfs integration suite

Boots a real SeaweedFS cluster (master + volume + filer) plus the
experimental `weed nfs` frontend as subprocesses and drives it through
the NFSv3 wire protocol via go-nfs-client, mirroring the layout of
test/sftp. The tests run without a kernel NFS mount, privileged ports,
or any platform-specific tooling.

Coverage includes read/write round-trip, mkdir/rmdir, nested
directories, rename content preservation, overwrite + explicit
truncate, 3 MiB binary file, all-byte binary and empty files, symlink
round-trip, ReadDirPlus listing, missing-path remove, FSInfo sanity,
sequential appends, and readdir-after-remove.

Framework notes:

- Picks ephemeral ports with net.Listen("127.0.0.1:0") and passes
  -port.grpc explicitly so the default port+10000 convention cannot
  overflow uint16 on macOS.
- Pre-creates the /nfs_export directory via the filer HTTP API before
  starting the NFS server — the NFS server's ensureIndexedEntry check
  requires the export root to exist with a real entry, which filer.Root
  does not satisfy when the export path is "/".
- Reuses the same rpc.Client for mount and target so go-nfs-client does
  not try to re-dial via portmapper (which concatenates ":111" onto the
  address).

* ci: add NFS integration test workflow

Mirror test/sftp's workflow for the new test/nfs suite so PRs that touch
the NFS server, the inode filer plumbing it depends on, or the test
harness itself run the 14 NFSv3-over-RPC integration tests on Ubuntu
22.04 via `make test`.

* nfs: use append for buffer growth in Write and Truncate

The previous make+copy pattern reallocated the full buffer on every
extending write or truncate, giving O(N^2) behaviour for sequential
write loops. Switching to `append(f.content, make([]byte, delta)...)`
lets Go's amortized growth strategy absorb the repeated extensions.
Called out by gemini-code-assist on PR 9067.

* filer: honor caller cancellation in collectInodeIndexEntries

Dropping the WithoutCancel wrapper lets DeleteFolderChildren bail out of
the inode-index scan if the client disconnects mid-walk. The cleanup is
already treated as best-effort by the caller (it logs on error and
continues), so a cancelled walk just means the partial index rebuild is
skipped — the same failure mode as any other index write error.
Flagged as a DoS concern by gemini-code-assist on PR 9067.

* nfs: skip filer read on open when O_TRUNC is set

openFile used to unconditionally loadWritableContent for every writable
open and then discard the buffer if O_TRUNC was set. For large files
that is a pointless 64 MiB round-trip. Reorder the branches so we only
fetch existing content when the caller intends to keep it, and mark the
file dirty right away so the subsequent Close still issues the
truncating write. Called out by gemini-code-assist on PR 9067.

* nfs: allow Seek on O_APPEND files and document buffered write cap

Two related cleanups on filesystem.go:

- POSIX only restricts Write on an O_APPEND fd, not lseek. The existing
  Seek error ("append-only file descriptors may only seek to EOF")
  prevented read-and-write workloads that legitimately reposition the
  read cursor. Write already snaps the offset to EOF before persisting
  (see seaweedFile Write), so Seek can unconditionally accept any
  offset. Update the unit test that was asserting the old behaviour.
- Add a doc comment on maxBufferedWriteSize explaining that it is a
  per-file ceiling, the memory footprint it implies, and that the real
  fix for larger whole-file rewrites is streaming / multi-chunk support.

Both changes flagged by gemini-code-assist on PR 9067.

* nfs: guard offset before casting to int in Write

CodeQL flagged `int(f.offset) + len(p)` inside the Write growth path as
a potential overflow on architectures where `int` is 32-bit. The
existing check only bounded the post-cast value, which is too late.
Clamp f.offset against maxBufferedWriteSize before the cast and also
reject negative/overflowed endOffset results. Both branches fall
through to billy.ErrNotSupported, the same behaviour the caller gets
today for any out-of-range buffered write.

* nfs: compute Write endOffset in int64 to satisfy CodeQL

The previous guard bounded f.offset but left len(p) unchecked, so
CodeQL still flagged `int(f.offset) + len(p)` as a possible int-width
overflow path. Bound len(p) against maxBufferedWriteSize first, do the
addition in int64, and only cast down after the total has been clamped
against the buffer ceiling. Behaviour is unchanged: any out-of-range
write still returns billy.ErrNotSupported.

* ci: drop emojis from nfs-tests workflow summary

Plain-text step summary per user preference — no decorative glyphs in
the NFS CI output or checklist.

* nfs: annotate remaining DEV_PLAN TODOs with status

Three of the unchecked items are genuine follow-up PRs rather than
missing work in this one, and one was actually already done:

- Reuse chunk cache and mutation stream helpers without FUSE deps:
  checked off — the NFS server imports weed/filer.ReaderCache and
  weed/util/chunk_cache directly with no weed/mount or go-fuse imports.
- Extract shared read/write helpers from mount/WebDAV/SFTP: annotated
  as deferred to a separate refactor PR (touches four packages).
- Expand direct data-path writes beyond the 64 MiB buffered fallback:
  annotated as deferred — requires a streaming WRITE path.
- Shared lock state + lock tests: annotated as blocked upstream on
  go-nfs's missing NLM/NFSv4 lock state RPCs, matching the existing
  "Current Blockers" note.

* test/nfs: share port+readiness helpers with test/testutil

Drop the per-suite mustPickFreePort and waitForService re-implementations
in favor of testutil.MustAllocatePorts (atomic batch allocation; no
close-then-hope race) and testutil.WaitForPort / SeaweedMiniStartupTimeout.
Pull testutil in via a local replace directive so this standalone
seaweedfs-nfs-tests module can import the in-repo package without a
separate release.

Subprocess startup is still master + volume + filer + nfs — no switch to
weed mini yet, since mini does not know about the nfs frontend.

* nfs: stream writes to volume servers instead of buffering the whole file

Before this change the NFS write path held the full contents of every
writable open in memory:

  - OpenFile(write) called loadWritableContent which read the existing
    file into seaweedFile.content up to maxBufferedWriteSize (64 MiB)
  - each Write() extended content in-place
  - Close() uploaded the whole buffer as a single chunk via
    persistContent + AssignVolume

The 64 MiB ceiling made large NFS writes return NFS3ERR_NOTSUPP, and
even below the cap every Write paid a whole-file-in-memory cost. This
PR rewrites the write path to match how `weed filer` and the S3 gateway
persist data:

  - openFile(write) no longer loads the existing content at all; it
    only issues an UpdateEntry when O_TRUNC is set *and* the file is
    non-empty (so a fresh create+trunc is still zero-RPC)
  - Write() streams the caller's bytes straight to a volume server via
    one AssignVolume + one chunk upload, then atomically appends the
    resulting chunk to the filer entry through mutateEntry. Any
    previously inlined entry.Content is migrated to a chunk in the same
    update so the chunk list becomes the authoritative representation.
  - Truncate() becomes a direct mutateEntry (drop chunks past the new
    size, clip inline content, update FileSize) instead of resizing an
    in-memory buffer.
  - Close() is a no-op because everything was flushed inline.

The small-file fast path that the filer HTTP handler uses is preserved:
if the post-write size still fits in maxInlineWriteSize (4 MiB) and
the file has no existing chunks, we rewrite entry.Content directly and
skip the volume-server round-trip. This keeps single-shot tiny writes
(echo, small edits) cheap while completely removing the 64 MiB cap on
larger files. Read() now always reads through the chunk reader instead
of a local byte slice, so reads inside the same session see the freshly
appended data.

Drops the unused seaweedFile.content / dirty fields, the
maxBufferedWriteSize constant, and the loadWritableContent helper.
Updates TestSeaweedFileSystemSupportsNamespaceMutations expectations
to match the new "no extra O_TRUNC UpdateEntry on an empty file"
behavior (still 3 updates: Write + Chmod + Truncate).

* filer: extract shared gateway upload helper for NFS and WebDAV

Three filer-backed gateways (NFS, WebDAV, and mount) each had a local
saveDataAsChunk that wrapped operation.NewUploader().UploadWithRetry
with near-identical bodies: build AssignVolumeRequest, build
UploadOption, build genFileUrlFn with optional filerProxy rewriting,
call UploadWithRetry, validate the result, and call ToPbFileChunk.
Pull that body into filer.SaveGatewayDataAsChunk with a
GatewayChunkUploadRequest struct so both NFS and WebDAV can delegate
to one implementation.

- NFS's saveDataAsChunk is now a thin adapter that assembles the
  GatewayChunkUploadRequest from server options and calls the helper.
  The chunkUploader interface keeps working for test injection because
  the new GatewayChunkUploader interface is structurally identical.
- WebDAV's saveDataAsChunk is similarly a thin adapter — it drops the
  local operation.NewUploader call plus the AssignVolume/UploadOption
  scaffolding.
- mount is intentionally left alone. mount's saveDataAsChunk has two
  features that do not fit the shared helper (a pre-allocated file-id
  pool used to skip AssignVolume entirely, and a chunkCache
  write-through at offset 0 so future reads hit the mount's local
  cache), both of which are mount-specific.

Marks the Phase 2 "extract shared read/write helpers from mount,
WebDAV, and SFTP" DEV_PLAN item as done. The filer-level chunk read
path (NonOverlappingVisibleIntervals + ViewFromVisibleIntervals +
NewChunkReaderAtFromClient) was already shared.

* nfs: remove DESIGN.md and DEV_PLAN.md

The planning documents have served their purpose — all phase 1 and
phase 2 items are landed, phase 3 streaming writes are landed, phase 2
shared helpers are extracted, and the two remaining phase 4 items
(shared lock state + lock tests) are blocked upstream on
github.com/willscott/go-nfs which exposes no NLM or NFSv4 lock state
RPCs. The running decision log no longer reflects current code and
would just drift. The NFS wiki page
(https://github.com/seaweedfs/seaweedfs/wiki/NFS-Server) now carries
the overview, configuration surface, architecture notes, and known
limitations; the source is the source of truth for the rest.
