readme: get to the point (#11120)
Lead with what SeaweedFS is and how to start it: one command, Docker, Docker Compose, a production-shaped Helm values file, build from source, scale out. Then why: fast, scalable, the S3 API surface with operation counts, the lakehouse with S3 Tables and the engines that share it, the cloud cache, and cross-cluster replication and the rest of the feature list, each pointing at its wiki page. The blob store walkthrough and the master and volume server internals move to the Blob Store Architecture wiki page. The comparisons, benchmark, enterprise and license sections stay. The dev plan is gone, it was done. Claude-Session: https://claude.ai/code/session_014apMEkkquAtAYp89paTkAT |

shell: exit non-zero when a piped command fails (#11117)
* shell: non-interactive mode exits non-zero when a command fails A failed command in a piped weed shell run printed 'error: ...' but the process still exited 0, so a CronJob wrapping e.g. echo 's3.lifecycle.run-shard -shards 0-15' | weed shell -master=... reported green while the run aborted partway (shards N+1..15 unwalked). An unknown command likewise exited 0. RunShell now returns the last command failure from the non-interactive stdin path (unknown commands included), and the shell command exits 2 on it. Interactive sessions are unchanged: errors are shown to the operator and the session continues, exiting 0 as before. * shell: route the piped-failure exit through main's shutdown path Review follow-up: os.Exit(2) inside the shell command skipped main's shutdown work. The command now records the status (SetCommandExitStatus) and returns normally; main applies it via setExitStatus before exit(). exit() itself now flushes sentry before os.Exit -- main's deferred sentry.Flush never ran on this path (os.Exit skips defers), so the existing 'flush buffered events before the program terminates' intent only worked for the autocomplete early-return. Exit status 2 on a failed piped run is preserved (verified: piped success exits 0, piped failing command exits 2). * shell: test the registered-command failure path Review follow-up: the error-propagation test only covered unknown commands. A fake registered command now drives processEachCmd's real dispatch path: a failing Do surfaces its exact error (errors.Is) and a succeeding one returns nil. The non-interactive exit status itself is main-level plumbing, verified end to end against the reproduction (piped failure exits 2). * shell: trim the comments added with the exit status Keep the non-obvious why -- why a piped run has to fail its wrapper, why the status is recorded instead of os.Exit'ed -- and drop the narration. Claude-Session: https://claude.ai/code/session_018DWwctzD4T2DmnczPRM47t * shell: fail a piped run with the status weed already uses for that weed.go spends 1 on a command that failed and 2 on a usage or syntax error, and runShell returns true precisely so the usage dump is skipped. Exiting 2 there told a wrapper the command line was wrong. Claude-Session: https://claude.ai/code/session_018DWwctzD4T2DmnczPRM47t --------- Co-authored-by: Carlos Leyva <carlos.leyva@idener.es> |

filer: SQL store pool defaults that survive a concurrent walk (#11110)
* filer: SQL store pool defaults survive concurrent walks (idle == open == 50, lifetime 300s) The code defaults for the four SQL stores were connection_max_idle=2 with NO default for connection_max_open (unlimited) or lifetime, while the scaffold filer.toml documents 10/50/300 -- so an env-configured or minimal-toml filer got the worst possible pool. Under a concurrent listing burst (s3.lifecycle.run-shard walks 16 shards in parallel) every operation released above the 2 idle slots closes its TCP connection, so the walk opens a fresh connection per operation until the filer exhausts its ephemeral ports: list /buckets/... : failed to connect ... dial tcp ...:5432: connect: cannot assign requested address Measured on a production filer: 0 -> 28k TIME_WAIT with only ~1.3k concurrent, and in the minimal docker-compose reproduction (2000-dir bucket, port range narrowed to 400): the whole range in TIME_WAIT with only ~12 ESTABLISHED. Default all three knobs, with idle == open so released connections are kept and reused: idle connections only accumulate up to the actual peak concurrency and connection_max_lifetime_seconds recycles them, so a quiet deployment holds nothing extra. An explicit 0 still disables the caps as before. The scaffold's connection_max_idle moves 10 -> 50 to match. With this change the same reproduction completes all 16 shards with the default configuration (TIME_WAIT peak 19 vs the whole port range). * filer: trim the SQL pool default comments One line of the non-obvious why is enough; the rest narrated the code. Claude-Session: https://claude.ai/code/session_018DWwctzD4T2DmnczPRM47t * filer: leave the SQL stores' connection_max_open unset A listing holds its connection for the whole row iteration while its callback runs another query -- FilerStoreWrapper.maybeReadHardLink does a KvGet per hard-linked entry -- so every concurrent listing needs two connections from the same pool. With a default cap, listings past the cap wedge: 60 concurrent listings over hard-linked entries made no progress at all against a 50 connection pool, and the wrapper's context.WithoutCancel leaves the waiters without a deadline. The idle pool is what fixes the connection churn: idle 50 with an unbounded max_open holds the same 14 postgres sessions across a 16-way listing burst that opened 455 with idle 2.

mount: name the disk without changing what is mounted (#11114)
mount: name the disk after the mount point when the whole tree is mounted The mounted path was the only thing that named the disk, so a mount of the whole tree was labelled with the filer address and the only way to give it a name was to mount a subtree under that name — which hides everything outside it. Fall back to the mount point's own name first, so -dir=\\seaweedfs\Images labels the disk while -filer.path stays "/". Claude-Session: https://claude.ai/code/session_01Q9f8pWBXu1ceJvcQfYRQ7x |

fix(mount): make a concurrent duplicate mkdir fail with EEXIST instead of both succeeding (#11079)
* fix(mount): make Mkdir exclusive so a concurrent duplicate fails with EEXIST Mkdir sent CreateEntryRequest without OExcl, so the filer treated a concurrent duplicate as an update and reported success to both callers; the kernel's pre-mkdir lookup only masks this when the winner's create is already visible. Set OExcl, map the entry-already-exists sentinel to EEXIST instead of EIO, and drop the parent's children cache on the losing side so the next lookup fetches the winner's entry. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(mount): route exclusive creates to the path's owner filer The filer's per-path lock is filer-local and the store insert has upsert semantics, so two mounts streaming to different filers can both create the same path even with OExcl (measured 18/30 both-success on a 3-filer cluster). Hash the path over the sorted filer list so every mount sends the same path's exclusive create to the same owner filer: keep the mutation stream when it already targets the owner, fall back to it when the owner is unreachable. Also let doUnary hand failed creates to CreateEntry so the structured error code survives as EEXIST instead of collapsing into the stream's generic EIO. Same race after the change: 30/30 exactly one winner, every loser fails with EEXIST. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(mount): review fixes — pin exclusive creates to the owner filer An OExcl create now goes only to the path's owner filer: retrying on a different filer would race the owner's possibly still-in-flight create through a separate per-path lock, the very hole this routing closes. A broken mutation stream retries the same owner over unary, and an unreachable owner fails the create instead of degrading. Pick the owner by rendezvous hashing so the choice is independent of the configured filer order, and mounts configured with different but overlapping lists still agree wherever the winning filer appears in both. Reject a stream create wrapper whose nested response is nil instead of handing it to CreateEntry, which would dereference it. Add ownerFilerAddress unit tests: order independence, subset agreement, spread. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * mount: drop the client-side owner ring, the filer routes exclusive creates now Exclusive creates are arbitrated cluster-wide on the server: the filer resolves an OExcl create's ring owner and forwards one hop, so one filer's per-path lock binds every creator — mount, S3, the HTTP surface and the Java client alike, not only the ones that opted into a client-side ring. That makes exclusiveCreateEntry redundant. It hashed the mount's configured -filer list, which names a different owner than the master-maintained ring, and failed the mkdir outright when its chosen owner was unreachable rather than letting the ring reassign. Mkdir goes back to streamCreateEntry; OExcl and the EEXIST mapping stay, and now mean what they say. Claude-Session: https://claude.ai/code/session_01Fx1Hx8RqsJqHpbfbgTf4WJ * mount: cover the create error plumbing that turns a lost race into EEXIST Letting a failed create's structured code survive doUnary is what makes a lost mkdir race report EEXIST instead of EIO, and it had no test. Pull the two steps out so they can be exercised without a live stream: hasCreateResponse decides whether a response still carries a code to unwrap, createEntryFromResponse does the unwrapping. Reading the guard the other way round also says what it means — consume the response only when there is no nested code left to recover — rather than negating a type assertion inline. Claude-Session: https://claude.ai/code/session_01Fx1Hx8RqsJqHpbfbgTf4WJ * mount: do not trust a create reply's shape before reading it createEntryFromResponse read cr.ErrorCode without checking the nested response was there. Nothing our filer sends is shaped that way, but the mount reads this off the wire and a nil there panics the whole mount, so report it instead. A top-level failure whose nested response carries no code was also returned as success, silently losing the error. Fall back to the top-level errno when the nested response explains nothing.

lance: a maintenance job that sorts a table by its declared fields (#11113)
* lance: a maintenance job that sorts a table by its declared fields Lance appends fragments in write order and has no notion of a sorted table, so nothing but a rewrite establishes one, and nothing but another rewrite restores it once rows have been appended. lance_sort reads the order from the dataset's own configuration, falls back to the worker's, and rewrites the table in it. The spec and the marker live in crates/sort rather than in the job, because weed/worker/tasks/iceberg sorts too: two jobs that disagreed about what "id desc nulls-first" means would be two features wearing one name. The sort spills. lance builds its DataFusion runtime with a FairSpillPool and a disk manager, but only when LanceExecutionOptions::use_spilling is set, and that struct derives Default over a plain bool — so Scanner::try_into_stream, which fills its options with ..Default::default(), is precisely the path that does not spill. The job builds the plan with create_plan and executes it with spilling on and the operator's memory budget. The marker rides in the same commit as the data: Operation::Overwrite is the one operation carrying config values alongside fragments, so a sorted table and the record of its sorting cannot disagree. It records the version the sort read, not the one it wrote, which is not knowable while the marker is being assembled. Detection treats anything committed after the sort's own commit as data the sort did not produce — row counts alone cannot see a rewrite that leaves the count where it was, and such a table would look sorted forever. Claude-Session: https://claude.ai/code/session_015SZkLTUvd1svDu4xdr6Q3y * lance: identify a sorted table by the files it wrote, not its version Review found three ways the version-based marker misjudges a table, and they share a cause: the version a sort produces is not knowable while the marker is being assembled, so the marker recorded the version it read and detection inferred the rest. A commit that rebases past a conflict lands on a different number, and the inference then reads a rewrite into an ordinary table — a full re-sort, and its indices, for nothing. Data file names do not have that problem. They are chosen before the commit, so the commit can carry them, and they do not change with the version it lands on. The marker now records how many files the sort wrote and a digest of their names, and detection asks whether the table still holds them: the same files means untouched, the same files followed by more means appended, anything else means the data was replaced. That also closes the hole the row threshold left. A replacement that grew the table by fewer rows than min_unsorted_rows read as sorted, however many rows had actually moved; the threshold now applies only where the sorted files are still in place, which is what it was for. A marker without a row count is stale rather than a zero to compare against, and deletes stop forcing a re-sort — they write a deletion file beside the data rather than rewriting it, and removing rows does not unsort the ones that remain. Sort fields are also compared exactly rather than case-folded. Arrow schemas are case-sensitive, so `id` and `ID` are two columns, and folding them together rejected a valid order. Claude-Session: https://claude.ai/code/session_015SZkLTUvd1svDu4xdr6Q3y * lance: count the rows appended after a sort, not the table's net growth Review found that rows deleted from the sorted fragments hide appended rows one for one: the threshold compared the live row count against the count recorded at sort time, so 800 deletions and 300 appends read as a table that shrank, and a table where deletions keep pace with appends stays "sorted" with an unsorted tail forever. The fragments say it directly. The marker already records how many fragments the sort wrote, so the ones after that prefix are exactly what arrived since, and the manifest carries each fragment's live row count — physical rows less its deletions. Counting those is the arithmetic the threshold was always meant to do, and it needs no row count from the marker at all. A fragment whose length the manifest does not record cannot be counted, and a table that cannot be judged is one to sort rather than one to leave alone forever, so an uncountable appended fragment reads as stale.

iceberg: sort compaction bins on disk instead of in memory (#11112)
A sorted rewrite collected every row of a bin into one slice and sorted it there, so a bin larger than the worker's heap could not be sorted at all. sort_max_input_mb existed for that reason and skipped the bins it capped. parquet-go's SortingWriter buffers sort_buffer_rows rows, encodes each buffer as a sorted run, and merges the runs at close; backing those runs with a FileBufferPool keeps them in files rather than on the heap. sort_spill_dir says where, defaulting to the system temp directory — NewFileBufferPool resolves an empty path to the working directory, which is not what an unset setting means. The output now also declares its sorting columns, which the plain writer the sorted path used never did. Claude-Session: https://claude.ai/code/session_015SZkLTUvd1svDu4xdr6Q3y |

filer: route exclusive and conditional creates to the entry's ring owner (#11109)
* proto: resync the java copy of filer.proto The Makefile keeps other/java/client/src/main/proto/filer.proto a verbatim copy, but AssignVolumeResponse.fsync and SubscribeMetadataResponse.flushed_ts_ns landed without it. Copy them over; no behaviour change. Claude-Session: https://claude.ai/code/session_01Fx1Hx8RqsJqHpbfbgTf4WJ * filer: route exclusive and conditional creates to the entry's ring owner CreateEntry with o_excl is a FindEntry-then-Insert. The per-path lock added for it makes that atomic only on the filer running it, and the store's insert is an upsert on every backend, so two filers both pass the existence check and both report success. mkdir(2) then succeeds twice for the same path. The same hole sits under the condition precondition, whose comment already told callers to route the key's writes to the owner filer themselves. Do it on the server instead, with the mechanism ObjectTransaction already uses: resolve the entry's ring owner and forward one hop, bounded by is_moved. The ring's membership comes from the master, so it tolerates a stale view and reassigns when a filer dies, neither of which a client's configured filer list can do. Every creator gets this — mount, S3, the filer's own HTTP surface, the Java client — not only the ones that opted in. Plain creates are upserts whoever applies them, so they stay local and pay nothing. The route key shares the S3 gateway's namespace so an object's ObjectTransaction and its CreateEntry land on the same filer's per-path lock.

filer: keep a moved key on its prior owner while the ring settles (#11108)
ObjectTransaction forwards to the ring owner so one filer's per-path lock arbitrates every writer of a key. But a ring change hands the key over before the new owner has rebuilt the locks the prior owner still holds, so for the cooling-off window both can grant it. LockRing.PriorOwner exists for exactly this and nothing consulted it. Route to the prior owner while that window is open. LockRing.WriteOwner resolves prior-else-current under one read lock, so the pair cannot come from different rings and name the same filer twice. An unreachable owner fails the request rather than falling back to the current one. gRPC reports a response lost in transit as Unavailable, indistinguishable from a request the owner never saw, so re-sending elsewhere could re-apply what the owner already committed; and an owner unreachable from here may be partitioned rather than down, still serving the key to everyone else — which is the split brain the routing exists to prevent. The window is bounded: once it closes the ring hands the key to its new owner. The owner resolution and the forward move into writeOwner/forwardToWriteOwner so the next routed RPC reuses them rather than copying the block.

filer: self-heal chunk manifest reads when volume locations go stale (#11107)
* filer: self-heal fetchWholeChunk on stale volume locations Upstream #10156/#10800 wired cache invalidation into the buffer-based read paths, but manifest resolution still goes through fetchWholeChunk, which returns the raw error on failure. When cached volume locations are stale (volume tiered to remote storage, server rolled), resolving a large multipart file fails permanently even though other locations are healthy. Thread the ChunkGroup's cacheInvalidator through ResolveChunkManifest / ResolveOneChunkManifest / fetchWholeChunk, and on failure invalidate, re-lookup and retry once via the existing retryFetchWithFreshLocations helper. The streaming bytesBuffer is reset before the retry so partial bytes from the failed attempt cannot corrupt the manifest proto.Unmarshal. Non-mount callers pass nil and keep their semantics. * filer: move the manifest self-heal tests in with the other manifest tests Also make the stale server stream a prefix and then abort mid-body, which is what actually leaves partial bytes in the buffer: an HTTP error status returns before ReadUrlAsStream ever calls the writer, so a 500 never exercised the Reset the tests claimed to cover. Claude-Session: https://claude.ai/code/session_01FK3oGC5ZVeJYvNBWgb9JUD * filer: keep the cached volume locations when a manifest read is cancelled A cancelled or timed-out read says nothing about where the volume lives, so dropping the location and going back to the master only costs the next reader a round trip. PrepareStreamContentWithThrottler already guards its self-heal this way. The guard also goes inside retryFetchWithFreshLocations, since the caller can be cancelled between its own check and the invalidation, and that covers the reader cache and prefetch paths too. fetchWholeChunk returns the context error rather than the stream failure it provoked, and ResolveOneChunkManifest wraps with %w so errors.Is still sees it. That matters even where no invalidator is passed: volume.fsck resolves manifests with nil and tells its own abort from a corrupt manifest that way, so the cancellation check sits ahead of the nil-invalidator return. Claude-Session: https://claude.ai/code/session_01FK3oGC5ZVeJYvNBWgb9JUD * filer: self-heal manifest reads on the filer and s3 paths too Every caller that already holds the location cache backing its lookup function can hand it over: the filer's read, copy and deletion paths and the log cache have the MasterClient right there, and s3api has the FilerClient. MinusChunks takes one for the same reason, since the deletion path resolves manifests through it. Only the shell tools and the replication sinks, whose lookup functions cache privately with nothing to invalidate, keep passing nil.

shell: clean up the target copy when a merge upload fails (#11104)
* shell: clean up the target copy when a merge upload fails A replicated write commits the needle to the local volume before it fans out to the other replicas, so an upload that reports failure can still have left a copy on the target. fs.mergeVolumes printed "failed to move" and carried on, so that copy stayed behind forever: the filer is never re-pointed at it, and nothing else knows it exists. One sick replica orphans roughly half the chunks of a merge, two thirds with three copies, since the entry node is picked at random from the replicas and the replica upload uses MaxAttempts 1. A volume with a single copy has no such window: the write is one local append that either succeeds or leaves nothing. Delete the needle we may have written before continuing. The source side already did exactly this, so deleteMovedSourceNeedles is renamed to deleteOrphanedNeedles and reused for both ends. Claude-Session: https://claude.ai/code/session_01XjiMGK72F4Gs3yWNJhnVjy * shell: verify the cookie before deleting a merge target needle The target cleanup deletes a needle an upload may or may not have written, and BatchDelete matches on the needle id alone. Needle ids come from one global sequence, so normally nothing else can hold that id — but a volume restored from elsewhere, or one written either side of a master sequence reset, can, and then a failed move deletes a live needle out from under its filer entry. Have the volume server verify the cookie for those. Source needles keep deleting by id: they are the ones the filer just pointed at, matching every other filer-driven delete. Claude-Session: https://claude.ai/code/session_01XjiMGK72F4Gs3yWNJhnVjy * shell: delete the target copies an abandoned manifest rewrite leaves rewriteManifestChunk moves sub-chunks one at a time and only then uploads the rewritten manifest. Every error after the first successful move — a nested rewrite failing, the marshal, the manifest upload — returned without touching the copies already written to the target volumes. The filer keeps pointing at the old manifest, so those copies orphan, one per sub-chunk moved so far. Track them alongside the sources and delete them on the way out. Nested rewrites hand theirs up so an outer failure clears the whole subtree. A failed UpdateEntry deliberately still leaks its copies: that error can also mean the filer applied the update and lost the response, and deleting there would turn a leak into data loss. Claude-Session: https://claude.ai/code/session_01XjiMGK72F4Gs3yWNJhnVjy * shell: give the plan its room back when a manifest rewrite is abandoned allocate reserves plannedSize against the chosen target for every move a multi-target source makes, and release hands it back when the move fails. Abandoning a manifest rewrite now deletes the copies that did land, so those reservations stopped matching anything on disk: the plan kept counting bytes that are gone and refused later chunks with "no target volume has room". Release them alongside the delete. Nested rewrites hand theirs up so an outer failure unwinds the whole subtree's accounting. Claude-Session: https://claude.ai/code/session_01XjiMGK72F4Gs3yWNJhnVjy |

avro: field time.Time <> iceberg.date (#11091)
* iceberg: normalize foreign day partitions during manifest rewrite * test: cover manifest rewrite with foreign day partitions * iceberg: restore every foreign partition value, not just day transforms iceberg-go takes a partition field's logical type from the last branch of its Avro union, so a writer that spells an optional partition [<type>, null] rather than [null, <type>] leaves the value as whatever the Avro decoder produced. A day or date partition then arrives as a time.Time the manifest writer cannot encode, and a time partition is worse: time.Duration converts to int64 nanoseconds and silently records the wrong value. ReadManifest sits next to ReadManifestList, the other shim for what foreign writers put on the wire, and converts each partition value back to the Iceberg representation for its field type. Claude-Session: https://claude.ai/code/session_01FdQyRuWF9SuCnPn21iH9yR * iceberg: read manifests that carry partition values through the shim Compaction, delete rewrite and their detection passes read entries and write the same partition values back into new manifests, so they fail on a foreign day partition exactly as manifest rewrite does. Where filters see it too: literalMatchesActual falls through to fmt.Sprint, so a time.Time renders as a timestamp and never matches the day the user asked for. The two remaining readers, orphan collection and the admin preview, only look at file paths and stay on iceberg.ReadManifest. Claude-Session: https://claude.ai/code/session_01FdQyRuWF9SuCnPn21iH9yR * iceberg: convert partition values before the writer rebinds logical types Dimonyga checked the manifests of a live Doris table: every input spells the partition union null-first, with the date logical type present, so the union ordering is not what breaks the merge. The conversion is lazy. iceberg-go converts what the Avro decoder returned on the first Partition() call, using the logical types read from the manifest being parsed, and ManifestWriter.addEntry rebinds them to the manifest it is about to write before it makes that call. A day partition is where the two disagree -- iceberg-go's day transform reports an int32 result type, so the manifest it writes carries no date logical type at all -- and an entry nobody looked at in between converts against that and keeps its time.Time. That is why only rewrite_manifests failed: compaction and delete rewrite group entries by partitionKey(df.Partition()) first, which converts them, and a where filter does the same. Reading every entry's partition here converts them all while the manifest's own logical types are still in place.

expose whether a volume replica is backed by remote storage, and prefer local replicas (#11105)
* expose whether a volume replica is backed by remote storage
Volume locations returned by lookups do not indicate whether a replica
has been tiered to remote storage. Readers cannot distinguish a local
replica from a remote-backed one, so they may hit a remote-backed
replica first even when a local replica is available.
Add DataInRemote to the lookup location message, populate it from the
master's volume info, and carry it through the wdclient vid map so
clients can prefer local replicas when resolving chunk locations.
* wdclient: prefer local volume replicas over remote-tier replicas on lookup
LookupFileIdWithFallback (and the publicUrl variant in FilerClient)
didn't honor the DataInRemote flag when shuffling URLs, so the
DataInRemote patch only took effect in LookupVolumeServerUrl. Apply
the same ReorderToFront(localUrls) to sameDcUrls/otherDcUrls so
non-remote replicas stay at the front, matching the existing vidMap
convention.
* wdclient: propagate DataInRemote across tier transitions on existing replicas
When a volume is tiered to remote storage or a remote-backed replica is
restored locally, the cached DataInRemote on the same volume-server URL
stayed at its old value because two pieces of state never updated:
* master_grpc_server.go only split newVolumes and (already-tracked) volumes
into NewVids vs RemoteVids. ChangedVolumes went straight to NewVids, so
the broadcast announced the re-classified volume as a fresh arrival and
the client had no way to tell whether its existing cache was stale.
* vid_map.addLocationToMap early-returned when an entry already had the
same URL. A tier transition reports the same URL with DataInRemote
flipped, so the cached entry stayed at the old classification.
Wire both sides together: ChangedVolumes now go through the same IsRemote
split as newVolumes, and addLocationToMap replaces the existing entry in
place when the URL matches but DataInRemote has changed. The server
reference key only depends on URL/grpc port, so the refcount does not
move across the flip.
Adds vid_map_remote_transition_test.go covering the local->remote and
remote->local paths so the in-place update and the cache-key stability
are pinned by tests.
* wdclient: prefer local replicas across data-center boundaries
The previous local-first ordering hoisted local URLs to the front of each
data-center bucket separately, then concatenated same-DC before other-DC.
That meant a same-DC remote replica could still be tried before an
other-DC local replica even though the local one would answer cheaply.
Reorder once across the full candidate list: concatenate same-DC and
other-DC first, then ReorderToFront pulls every local replica to the very
front while preserving the DC preference inside each tier. Apply the same
ordering in all four lookup paths so the cached vidMap, the
LookupFileIdWithFallback provider path, FilerClient.GetLookupFileIdFunction
(PublicUrl-preferred variant), and the deprecated filer.LookupFn all agree:
- weed/wdclient/vid_map.go (LookupVolumeServerUrl)
- weed/wdclient/vidmap_client.go (LookupFileIdWithFallback)
- weed/wdclient/filer_client.go (LookupFileId)
- weed/filer/reader_at.go (LookupFn)
Strengthen the existing local-first tests: vidmap_client_localfirst_test
now asserts both endpoints are present (not just the local one is first),
and slice_test asserts an exact match instead of accepting two orderings.
Add TestLookupFileIdWithFallbackGlobalLocalFirst to pin the cross-DC
ordering invariant: any local replica (same or other DC) precedes every
remote-tier replica; within each tier DC1 precedes DC2.
Add docstrings to ToVolumeLocations, ReorderToFront, LookupVolumeServerUrl,
LookupFileId, GetVidLocations, GetLocations, LookupFileIdWithFallback, and
updateVidMap so the touched lookup paths are described in one place.
* topology: broadcast tier transitions on existing replicas
When a volume replica is tiered to remote storage or restored locally, the
wdclient's cached DataInRemote went stale: every connected client kept
preferring a remote-backed replica over a freshly restored local one, or
demoted a freshly tiered remote replica. The fix in commit

s3: ListParts on a completed or unknown upload answers NoSuchUpload (#11081)
* s3: ListParts on a completed or unknown upload answers NoSuchUpload complete/abort delete the .uploads/<id> directory, but most filer stores list a missing directory as empty rather than erroring, so listObjectParts answered 200 with an empty Parts list for an upload that no longer exists -- the same response an open upload with no parts yet gets. AWS (and Ceph/RGW, MinIO) answer NoSuchUpload, and clients lean on that: tusd derives the resumable upload offset from the ListParts part sizes, so every completed upload read back as zero bytes received. Probe the upload record before listing, the way completeMultipartUpload already does: not found, or a directory a late part write resurrected without the destination key, answers NoSuchUpload. An open upload with no parts keeps answering 200 with an empty list. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01GGQEfVUvoATtwRCR8oC2jG * s3: have the ListParts test filer refuse a directory it was not asked about The fake answered the upload lookup on the name alone and the part listing regardless of directory, so a wrong genUploadsFolder or upload-id suffix would still have passed. Both calls now refuse any other directory with an Internal error, which surfaces as ErrInternalError rather than the NoSuchUpload the tests expect.

filer: keep empty folders that are s3tables catalog entries (#11102)
* s3tables: build the catalog attribute keys from one shared prefix Every attribute the catalog stores on a bucket, namespace, table or view entry is spelled out with the same literal prefix. Name it once in s3_constants so code outside the package can recognize a catalog entry without repeating the string. Claude-Session: https://claude.ai/code/session_01GfZsc4cyNB2yr6KYLRv9q1 * filer: keep empty folders that are s3tables catalog entries A namespace, table or view is a directory whose extended attributes are the catalog record. Its files can live elsewhere - a rename moves only the catalog pointer and leaves the data at the old path, and a view has no files at all - so an empty one is still a live entry. Drop a table, then rename another table onto that name: the drop queues the old table's folders, the rename recreates the name path, and two minutes later the cleaner deletes it and cascades into the namespace, losing a table the catalog still lists. Claude-Session: https://claude.ai/code/session_01GfZsc4cyNB2yr6KYLRv9q1 * filer: drop a queued cleanup when the folder is created again A cleanup is queued against the folder that was found empty. If that folder is deleted and a new one takes its name, the queue entry outlives the folder it was about and the next pass deletes the replacement. A drop followed by a rename onto the dropped name does exactly this: the name path comes back as a live catalog entry two minutes before the queue is read.

s3: validate the version-id header used as a filer path segment (#11097)
* s3: reject a version-id header that is not a valid path segment
putToFiler stored the client-supplied Seaweed-X-Amz-Version-Id header
verbatim into object metadata. That value is later read back and used
as a filer path component when building the .versions/v_<id> path, so a
value containing "/", "\" or ".." could steer retention/legal-hold
writes and remote-cache reads outside the object's own bucket tree.
Validate the header with isValidVersionID before storing it, the same
check the versioned read paths already apply, and reject the request
otherwise. Server-set version ids ("null" and generated hex) pass.
Claude-Session: https://claude.ai/code/session_011QqNaxZwnpHgMoAZNp3RkY
* s3: validate a stored version-id before using it as a path
The retention and legal-hold sinks build a .versions/v_<id> path from a
version id read back out of object metadata, and the remote-cache path
builder does the same from either the request or the stored id, without
the isValidVersionID check the other version-id consumers apply. Guard
these so a value that is not a valid path segment falls back to the
regular / unversioned path instead of steering the write or read out of
the bucket tree.

mini: expose -volume.max (#11100)
mini hardcoded the per-directory volume limit to 0, so the volume server always auto-sized it as free disk space divided by the volume size. That sizing reserves a whole volume size for every writable volume, so a workload spreading small objects over many buckets runs out of slots long before the disk fills and assign starts failing with "no free volumes left". Same name and semantics as the flag weed server already carries, and still 0 (auto) by default. Claude-Session: https://claude.ai/code/session_01BiQLeBvZLzG8XitjiypDKu |

test: metadata operations on unlinked open files and removed open directories (#11075)
The POSIX suites skirt this: pjdfstest's unlink/14.t covers only fstat and pread on an unlinked descriptor — its driver has no fchmod at all and never opens a directory. Pin the full rule in the FUSE integration suite: ftruncate, fchmod, futimes, fstat, and the f*xattr calls keep working between the removal of the last name and the final close, for a file after unlink and a directory after rmdir, with nlink 0 and the changes visible to a following fstat.

mount: keep metadata operations working on a removed open directory (#11073)
* mount: remember the entry of a directory removed while still referenced A directory removed while a descriptor is open on it keeps its inode until the kernel's final forget, but unlike a file it has no handle to live on through: OpenDir hands out only a listing cursor. Keep the last-known entry in memory, keyed by inode, from rmdir until that forget. Claude-Session: https://claude.ai/code/session_01GYqLENjZzbV5hgt4L8cSAK * mount: serve metadata ops on a removed open directory from its remembered entry fchmod, futimens, and the f*xattr calls on a descriptor whose directory was removed failed with ENOENT: maybeReadEntry resolved the inode to a path, and rmdir had already dropped it. Fall back to the remembered entry the same way an unlinked file falls back to its open handle. Mutations publish a changed copy back rather than editing in place, so a concurrent reader never sees a half-applied change, and the empty path keeps nlink 0 in every reply. Claude-Session: https://claude.ai/code/session_01GYqLENjZzbV5hgt4L8cSAK * mount: stash the entry the delete itself returned, not an earlier snapshot A chmod landing between Rmdir's entry load and the delete RPC would be resurrected pre-change: the remembered entry was the earlier local snapshot. The filer serializes the delete against updates under the path lock and hands the entry back in the delete event, so prefer that, keeping the local load for the sticky-bit check and as fallback when no event comes back. Claude-Session: https://claude.ai/code/session_01GYqLENjZzbV5hgt4L8cSAK * mount: drop a remembered entry whose insert lost to the final forget The forget's cleanup runs between RemovePath and the insert when the kernel evicts the inode concurrently, finds nothing, and the entry would sit in the map for the life of the mount. Re-check the inode after inserting and take the entry back out; every interleaving now ends with the map empty. Claude-Session: https://claude.ai/code/session_01GYqLENjZzbV5hgt4L8cSAK * mount: insert the remembered entry under the inode table lock The post-insert HasInode re-check could be fooled by inode number reuse: a lookup landing between the forget and the check makes the number look alive and the stale entry stays, keyed to someone else's inode. Do not check after the fact — RemovePath now runs the retention callback inside its critical section, where the forget that releases under the same lock cannot have run and cannot be missed. Publishes need no such fence: their open descriptor keeps the kernel from issuing the final forget in the first place. Claude-Session: https://claude.ai/code/session_01GYqLENjZzbV5hgt4L8cSAK |

s3api: push the listing prefix down to the filer in ListObjectVersions (#11070)
The version walk listed every directory with no prefix, transferring all 1024-entry batches over gRPC and filtering gateway-side - and kept paging past the point where names can no longer match. On wide directories (many sibling orgs/jobs next to the requested prefix) that is most of the transfer, decode, and CPU cost of every page. Derive the next path component of the requested prefix per directory level and hand it to the filer listing. A name holds no slash, so a directory whose name does not start with the component cannot contain a matching key and a file that does not cannot be one; stores with native prefixed listing (sql, leveldb) turn this into a range scan and stop the stream at the end of the prefix zone.

volume: an already-deleted EC needle is not a delete failure (#11071)
* volume: an already-deleted EC needle is not a delete failure Deleting a needle that is already gone is what the caller asked for, and the non-EC paths have always said so: BatchDelete reports StatusNotModified when DeleteVolumeNeedle finds nothing to do, and DeleteHandler answers 404 from its ReadVolumeNeedle pre-check. The EC branches had no such case, so ErrorDeleted fell through to a generic failure -- 500 from both, and DeleteHandler also counted it in VolumeServerFileWriteFailures, inflating a failure metric on a replayed or duplicated delete. The filer already tolerates this by string-matching "already deleted" on the result, which leaves an error message load-bearing; the status is now right at the source instead.

s3api: drop two redundant filer round-trips per listed version entry (#11068)
* s3api: drop two redundant filer round-trips per listed version entry ListObjectVersions paid two avoidable getEntry calls while walking a bucket, both re-fetching data the walk already held: - getObjectVersionList re-read the .versions directory entry that every caller had just received from listing the parent directory (or from its own sibling probe). Pass the entry down instead: one RPC saved per object listed. - getObjectOwnerFromVersion, on a version with no stamped owner, re-fetched the same version entry its OwnerID had been extracted from. The refetch cannot answer differently, so data written before owners were stamped cost one futile RPC per listed version, forever. All round-trips on this path are sequential, so on large versioned buckets (Veeam-style workloads) they add up to a visible share of per-page latency and gateway CPU. Claude-Session: https://claude.ai/code/session_01FquvGtTD2zA3uMZGQHAuV4 * s3api: treat a nil .versions entry as an empty version list filer_pb.GetEntry's contract permits (nil, nil) for an absent entry, and the old internal lookup answered that case with an empty list.

NotFound is an answer, not a transient failure: gate the retries on isRetryableFilerErr, the same classifier retryFilerOp already uses, which also stops retrying for callers whose context is canceled or past its deadline.

filer.sync: export replication lag, event counters, and in-flight jobs (#11069)
* filer.sync: count received, processed, and failed events and export in-flight jobs The metadata processor admits at most -concurrency jobs and blocks the subscription stream past that, so the backlog lives in the source filer's metadata log and cannot be counted here. What can be measured honestly: events read off the stream, replication outcomes, and worker saturation. in_flight_jobs pinned at the concurrency limit means the sync itself is the bottleneck; near zero means it is caught up or starved by the source. Claude-Session: https://claude.ai/code/session_01VGUXS7kdqiaXenTYVCg6vw * filer.sync: export replication lag in seconds Lag is now minus the freshest of the processed watermark and the last idle heartbeat: the watermark stops at the last real event, so a quiet caught-up stream would otherwise show phantom lag. A ticker drives the gauge because the offset callback only fires while events flow and freezes exactly when the workers are saturated. Until the first event or heartbeat the gauge stays unset rather than reporting lag against a zero or stale resume offset. Claude-Session: https://claude.ai/code/session_01VGUXS7kdqiaXenTYVCg6vw * filer.sync: track replicated data sizes alongside event counts An event count hides that 32 in-flight jobs can be 32 KB or 300 GB. Byte counters mirror the event counters, and in_flight_bytes pairs with in_flight_jobs. An event's size is the chunk delta - new chunks the old entry does not already have - so deletes, renames, and attribute-only updates count zero and byte rates reflect data movement, not metadata churn. Claude-Session: https://claude.ai/code/session_01VGUXS7kdqiaXenTYVCg6vw * grafana: chart the new filer.sync metrics The lag panel reads lag_seconds directly instead of deriving it from sync_offset, and the sync row gains event rate, throughput, and the in-flight jobs and bytes gauges. Claude-Session: https://claude.ai/code/session_01VGUXS7kdqiaXenTYVCg6vw * filer.sync: a pinned failure keeps showing as lag An idle heartbeat means the stream is consumed, not that every event replicated. While a permanent failure pins the watermark, letting the heartbeat advance lag_seconds or the sync_offset gauge would report a caught-up stream with an unreplicated event in it, so both now ignore heartbeats until a restart replays the failure. Claude-Session: https://claude.ai/code/session_01VGUXS7kdqiaXenTYVCg6vw * filer.sync: in-flight gauges survive subscription retries A subscription retry builds a new processor sharing the gauge children while the old processor's jobs may still be draining, so setting the gauge from either side's local count clobbers the other. Each job now increments and decrements for itself, keeping the total truthful across generations. Claude-Session: https://claude.ai/code/session_01VGUXS7kdqiaXenTYVCg6vw |

master: keep periodic volume growth to the data centers a layout lives in (#11060)
* master: keep the periodic growth scan to data centers hosting the layout The rack-aware scan planned growth for every data center in the topology, so a collection pinned to one DC (fs.configure -dataCenter) sprouted volumes in all the others within one scan cycle. Plan only for data centers already hosting the layout's volumes; an empty DC gets its volumes from the DC-constrained assign that first asks for them. The lastGrowCount divisor likewise counts only the racks the scan can plan for. Claude-Session: https://claude.ai/code/session_01J22TVTyoCMzdHyJirsLMG5 * master: pin periodic must-grow growth to a single-DC layout's data center The must-grow and crowded paths of the periodic loop grow with no DataCenter, so even with the scan fixed a pinned collection's volumes could still land in any DC once lastGrowCount demands more writables. Stamp the grow request with the layout's data center when its volumes all live in one; layouts spanning DCs keep unconstrained growth. Claude-Session: https://claude.ai/code/session_01J22TVTyoCMzdHyJirsLMG5 * master: never pin growth of a cross-DC-replicated layout A layout whose replication spans data centers cannot legitimately live in one DC; observing a single hosting DC there means the other DCs are down.

Stop once enough distinct DCs answer the caller's question: two for the single-DC check, the topology's DC count for the scan. A spanning million-volume layout now finishes in microseconds; only a layout truly confined to fewer DCs still pays a full walk, the same cost class as the under-replication count this loop already takes each cycle.

volume: open volume files with O_NOATIME (#11055)
* volume server: open volume files with O_NOATIME Nothing reads the atime of .dat, .idx, .sdx, or EC files, but every needle read still dirtied the inode: even relatime writes atime on the first read after each write, so an actively written volume paid a metadata write per read/write cycle, and strictatime mounts paid one per read.

master: scope the startup capacity shed to a truly empty topology (#11058)
* master: scope the startup capacity shed to a truly empty topology The retryable "no volume server capacity registered yet" shed checked capacity for the requested disk type, so a cluster serving only other media -- where that capacity will never register -- shed every assign until the client's deadline instead of failing fast. An unsteered write to such a cluster hung for its full HTTP deadline and surfaced "context deadline exceeded" in place of "No writable volumes". Shed only while no disk type has any registered capacity, and name the unserved medium in the fast failure. Claude-Session: https://claude.ai/code/session_01TF7FQghfDkpdoZgakTMX4R * master: name the unserved medium for every fail-fast caller The diagnostic sat in the growth-initiator block, so a follower joining an in-flight growth and a growth-disabled master failed the same way with only the generic pick error. Wrap at the fail-fast break instead, which every caller reaches, and cover all three paths in the test. Claude-Session: https://claude.ai/code/session_01TF7FQghfDkpdoZgakTMX4R |

shell: keep noLock to the command that set it (#11052)
noLock says "this invocation changes nothing" -- volume.balance, volume.move,
volume.copy, volume.merge and volume.fix.replication all set it for a dry run,
and none clears it. The CommandEnv is created once and reused by both
dispatchers, the interactive shell and the master's maintenance script runner,
so a simulation left every later command unlocked:
volume.balance -noLock # changes nothing
volume.move ... # mutates, and skips its lock
Reset before dispatch in both, where the invocation begins. forceNoLock is
untouched: that is set once, deliberately, for a trusted path.

s3: let attached policies authorize CreateBucket (#11049)
* s3: resolve admin bucket subresources to their specific S3 actions Encryption, requestPayment, publicAccessBlock and ownershipControls requests reached the policy engines as s3:*, so only a policy granting all of s3 could authorize them. Map each subresource to its AWS action, with DELETE sharing the PUT permission as AWS does. Claude-Session: https://claude.ai/code/session_01XH7iM88ZqWMEvsLB8tkWPQ * s3: authorize CreateBucket as s3:CreateBucket in the policy engine A plain bucket-level PUT is registered with ACTION_ADMIN, which resolved to s3:*, so no attached policy short of s3:* could match it. Federated sessions whose policy explicitly allowed s3:CreateBucket were always denied while the same policy worked for object operations. Resolve it to s3:CreateBucket, like DeleteBucket already resolves. Claude-Session: https://claude.ai/code/session_01XH7iM88ZqWMEvsLB8tkWPQ |

shell: keep fs.mergeVolumes from spinning past the finished moves (#11050)
* filer_pb: walk a re-delivered directory only once in TraverseBfs A directory handed back twice by a listing (a page-boundary race with concurrent renames, or a store whose ordering misbehaves) was enqueued twice; the second walk re-lists the same subtree and can keep the traversal from ever terminating. Claude-Session: https://claude.ai/code/session_01XH7iM88ZqWMEvsLB8tkWPQ * filer_pb: fail a directory listing whose pagination stops advancing A full page ending on the very name the cursor started from re-fetches the same page forever; a store whose listing order does not advance past the cursor turns any full-directory read into a silent infinite loop. Return an error naming the stuck cursor instead. Claude-Session: https://claude.ai/code/session_01XH7iM88ZqWMEvsLB8tkWPQ * shell: skip foreign-collection manifests in fs.mergeVolumes Every manifest chunk in the namespace was resolved, downloading its manifest needle, even when the merge plan only touches one collection. Sub-chunks live in the manifest's own collection, so a manifest on a volume outside the plan's collections cannot reference a source volume; skip it and spare a cluster-wide download pass that looks like a hang after the real moves finish.

sts: session duration no longer clamped to the web identity token exp (#11048)
* sts: session duration no longer clamped to the web identity token exp The assumed-role session lifetime is governed by DurationSeconds and the configured tokenDuration/maxSessionLength, matching AWS. Clamping to the already-verified token's exp made short-lived id_tokens (GitLab issues ~2-minute ones) yield unusable sessions regardless of configuration. Claude-Session: https://claude.ai/code/session_01XH7iM88ZqWMEvsLB8tkWPQ * sts: cover session duration against short-lived web identity tokens The mock OIDC provider now carries the token exp through to the identity like the real provider, so the integration test would catch the clamp.
