admin: bind to loopback by default, guard public unauthenticated bind (#11185)
admin: bind to loopback by default, refuse public unauthenticated bind The admin HTTP server (port 23646) defaulted to binding 0.0.0.0 with authentication disabled when -adminPassword was not supplied, exposing the full admin REST API (user creation, credential issuance, bucket deletion, filer deletion) unauthenticated on the network. This is the footgun described in GHSA-m3m8-mrgq-hf9h. Keep the no-auth mode for local dev, but remove the network exposure: - Add -ip flag (default 127.0.0.1) so the server binds loopback only unless the operator explicitly chooses a public address. - Refuse to start when binding a non-loopback address with no -adminPassword and no [https.admin] mTLS. The operator must enable auth or use loopback. - weed mini sets -ip from its existing -ip.bind; the guard does not apply because mini calls startAdminServer directly, not runAdmin. Addresses GHSA-m3m8-mrgq-hf9h. |

make the remote-mount cache wait configurable per mount (#11168)
* add a per-mount cache_wait_ms to the remote storage mount mapping A read of an uncached remote-only object waits on a hardcoded size tier before it can fall back to the origin, so every ranged read of a large remote-only object pays that wait. Carry the wait in the mount mapping so it can be tuned, or set to zero, per mount. * resolve the cache wait of an uncached remote-only read from its mount The wait came only from the object size, so an operator could not trade cache hits for time to first byte. Both read paths now resolve the mount covering the object and let its cache_wait_ms replace the size tiers. * read straight from the remote when a mount waits zero for its cache A mount used as a streaming source pays the cache wait on every ranged read of an object too large to finish caching, and the caching itself is wasted work. A zero wait now skips the cache call, so both read paths go to the origin immediately. * let remote.mount set the cache wait of a mount remote.mount -cacheWait=0 turns a mount into a streaming source, and any other duration trades cache hits against time to first byte. * keep the size based wait for a version-specific read A read pinned to a version cannot fall back to the origin, since the mounted remote only holds the current key, so a mount that opts out of caching would leave it on the 503 retry loop forever. * let the operator allow a remote-only read to dial an internal endpoint The remote-mount read paths in the filer and the S3 gateway always refused an endpoint resolving to a loopback or private host, so a mount backed by an internal S3 could never be read from its origin, only through the local cache. Both now take the allowance the volume server already has, still off by default. * skip the background cache of a mount that waits zero for its cache GetObjectHandler kicks off caching for every remote-only read, so a mount serving as a streaming source kept downloading whole objects even though no read ever waited for them. * cover a zero cache wait end to end The read has to reach a real origin, so the harness also opts the filer and the S3 gateway into dialing the loopback remote it already allows for the volume server. * resolve the S3 cache wait once so the background cache follows it too The background cache that GetObjectHandler starts read the mount on its own, so it skipped a version-specific read that the foreground path still waits for. Both now ask the same resolver. * answer 404 when the origin of a zero-wait read is gone Metadata can outlive the object it points at, and with no cache to fill the read would sit on the 503 retry path forever. The remote backends already report a missing object as ErrRemoteObjectNotFound. * open the origin at write time for a multipart range Every part of a multipart Range is prepared before any is written, so opening eagerly would hold one origin connection per part and leak the ones already opened when a later part fails to open. * reject a cache wait shorter than a millisecond The mapping stores milliseconds, so -cacheWait=500us truncated to zero and silently turned caching off instead of waiting. * restore the doc comment of cacheRemoteObjectForStreamingWithShortTimeout Extracting the wait resolver left its comment on the new function. * stat the origin before committing a multipart range Opening at write time keeps no connection through the preparation, but it also moved a failure past the point where the multipart body picks the response status, so a gone origin truncated a 206 instead of answering 404. One stat up front puts the status back. * stat the origin once per request Every part of a multipart Range is prepared on its own, so the preflight ran once per range instead of once per read. * map Azure and GCS stream not-found to ErrRemoteObjectNotFound ReadFileAsStream on Azure and GCS returned provider-specific not-found errors instead of ErrRemoteObjectNotFound, so a zero-wait read of a deleted object was misclassified as a transient cache failure and retried indefinitely. Map BlobNotFound and ErrObjectNotExist the same way StatFile already does. * Update weed/remote_storage/gcs/gcs_storage_client.go Co-authored-by: devin-ai-integration[bot] <158243242+devin-ai-integration[bot]@users.noreply.github.com> --------- Co-authored-by: devin-ai-integration[bot] <158243242+devin-ai-integration[bot]@users.noreply.github.com> |

mount: add -volumeName to name the disk explicitly (#11165)
* mount: let volumeName take an explicit override volumeName only ever derived the disk's label from -filer.path, -dir, or the filer address, so a name that happened to collide with something else - e.g. a UNC share's own name - could not be changed without moving what was mounted. Give it an override parameter that wins over all three; nothing passes one yet. * mount: add -volumeName to name the disk explicitly Windows has no equivalent of the "weed fuse" -o passthrough that lets a Linux or macOS mount override its derived volname, so a name picked up from -dir - e.g. a UNC share's own name - could not be changed short of moving what was mounted. -volumeName overrides it on every platform. * mount: document -volumeName * mount: scope -volumeName's help text to macOS and Windows Linux has no volume-label mount option for -volumeName to feed, so the flag's own description says where it applies instead of leaving that unstated. * mount: forward -volumeName through the weed fuse option parser weed fuse (the /etc/fstab helper) turns -o key=value into the same MountOptions weed mount takes, but volumeName had no case, so it fell through to being forwarded as a literal, unrecognized FUSE option instead of ever reaching mountOptions.volumeName. * mount: apply -volumeName to FsName on Linux and FreeBSD FsName only ever took the filer address and -filer.path, so -volumeName had nothing to override there and silently did nothing; the skipAutofs case still forces "fuse", since that name is what util-linux/mount requires to recognize the pseudo filesystem. |

filer: guard FoundationDB 100KB value limit and pack earlier (#11161)
* filer: guard the FoundationDB value size limit, not the transaction limit An entry's whole chunk list is one FoundationDB value, and FDB caps a value at 100,000 bytes while a transaction may reach 10MB. UpdateEntry checked the transaction limit, so every entry between the two limits passed the guard and was rejected by FDB itself with error 2103 (Value length exceeds limit). The failure surfaced inside the store rather than at the guard, so the S3 layer dropped the connection and clients saw a network fault instead of an error. Check the value limit in UpdateEntry and KvPut instead, after gzip and before the transaction, with an error that names the limit it hit. The removed transaction-size constant guarded nothing else: DeleteFolderChildren batches by entry count. Refs #11158 * filer: fold at 500 chunks in the foundationdb build Manifest packing is what keeps a large file's entry small, but it only ran once a flat chunk list reached 10000 chunks. A FoundationDB value stops at 100,000 bytes and an entry's whole chunk list is one value, which at ~100 bytes per chunk record is about 1000 chunks -- so on FDB the write always failed before packing could help: a 3.3 GiB PutObject at the default -maxMB=4 was already past the limit. FoundationDB support is its own build (`go build -tags foundationdb`, shipped as its own image), so the batch is a build-time choice and needs no negotiation at run time. The tagged build folds at 500, every other build keeps 10000 and is untouched. 500 is not arbitrary: a single fold level leaves (chunks/batch) manifest pointers plus up to (batch-1) unfolded chunks in the entry, so the reachable chunk count is highest when the two terms are near equal. For a 100,000-byte budget that optimum is 500, which holds an entry inside the limit up to ~250,000 chunks -- ~1 TB at -maxMB=4, against ~4 GB before. Larger files need nested packing, which no batch size substitutes for. One binary serves every role in that image, so the filer and each client that folds -- S3, mount, WebDAV, weed shell, filer.copy -- agree on the batch by construction. A binary built with the tag but pointed at another store folds earlier than that store requires, costing one manifest blob per 500 chunks and one read to resolve it. Fixes #11158 * filer: fold with rollback inside MaybeManifestize, not beside it A fold that fails midway has already uploaded manifest blobs for its earlier batches, and returns only the data chunks -- dropping the manifests it had separated out of the caller's list. Both were wrong in ways that mattered: - AppendToEntry assigned that shortened list straight to entry.Chunks and created the entry, so an append to an already-folded file whose fold failed lost every previously folded chunk. weed mount had the same shape. - cleanupChunks logged the error as "not good, but should be ok" and then returned it through a named result, failing the whole CreateEntry or UpdateEntry, while the blobs it had written stayed behind referenced by nothing. The S3 path was alone in handling this, through a private helper beside MaybeManifestize. A second entry point next to the one everything else calls just means the wrong one gets used, so the behaviour moves inside MaybeManifestize: on failure it returns inputChunks as it received them, and hands the blobs it saved to a deleteChunks callback. The filer, S3 and filer.copy pass their existing deleters -- filer.copy already cleans up this way after a failed upload -- and mount, WebDAV and weed shell pass nil, which reports the blobs rather than collecting them, as before. Each caller keeps its own error policy: the filer HTTP PUT path and filer.copy still fail the request, the rest still continue with the flat list, which is a correct entry. --------- Co-authored-by: Chris Lu <chris.lu@gmail.com> |

filer: authorize the chunk proxy and the root listing like the rest of the filer port (#11152)
* filer: require a read token for the root listing maybeCheckJwtAuthorization waved through every GET/HEAD on "/", so a filer with jwt.filer_signing.read.key set still served its root directory listing -- entry names, sizes and chunks[].file_id -- to a caller holding no token at all, and served the same listing to a token restricted by allowed_prefixes. The exemption was added for health checks before the filer had /healthz and /readyz. Both are registered on the default and read-only muxes ahead of the "/" handler and answer without a token, so drop it. Point the mTLS harness at /healthz, which is what it was probing for. * filer: keep the jwt query parameter out of a proxied chunk request The proxy stripped "jwt" from the forwarded query on reads only, on the grounds that a writer's own credential travels there. It does not: an uploader carries its AssignVolume token in the Authorization header, and the query parameter on this path holds a filer credential. Strip it for every method. A volume server has no business seeing a filer token, and because security.GetJwt reads the query before the header, relaying one would hide the writer's own token behind it. * filer: dispatch the chunk proxy after the JWT gate The ?proxyChunkId= branch returned before maybeCheckJwtAuthorization ran, so GET, PUT, POST and DELETE against any needle in the cluster were reachable on the filer's HTTP port with no filer credential, on a filer where every other request answered 401. An anonymous caller read a stored object, replaced its bytes, or deleted the needle, which the master's next vacuum makes permanent. #10434 stopped the filer from minting a volume write token for that caller, which closes the write half only where the volume server has a jwt.signing.key of its own -- not the shipped default, and not what scaffold/security.toml recommends for a filer deployment. The read half stayed open in every configuration, because the filer mints the read token itself. Move the dispatch below the gate. A file id carries no path, so a token restricted by allowed_prefixes cannot be scoped against one and is refused here; every consumer of this endpoint holds an unrestricted token. * filer: mint the volume credential for a proxied write too The proxy minted a volume token on reads and forwarded whatever the caller sent on writes. #10434 made it that way because the branch ran ahead of the JWT gate, so a token minted here would have been signed for an unauthenticated caller; the branch now runs behind the gate, and the credential the caller presents there is a filer one, which a volume server cannot validate and has no business seeing. Mint at the access level the request needs, and drop the caller's Authorization when there is no key to mint from. A proxied uploader then needs only the filer credential, instead of holding one for each hop with a single header to put them in. * mount, mq, filer.sync: send the filer credential for a proxied chunk Every in-tree consumer of ?proxyChunkId= reached the filer anonymously: mount and the broker put the AssignVolume token in the Authorization header, which is a volume credential, and filer.sync sent nothing at all. That was enough only while the branch ran ahead of the filer's JWT gate. Build the URL through one helper, and pick the credential from the URL it returns: a chunk proxied through a filer is a request to the filer, which authorizes it and attaches the volume credential itself, so the token there is a filer one at the access level the request needs. * filer: honor -exposeDirectoryData The flag was declared on all three commands that start a filer and read by none of them: FilerOption.ExposeDirectoryData was only ever assigned from filer.expose_directory_metadata in security.toml, so -exposeDirectoryData=false silently left the listing exposed. Only the TOML key had any effect. Plumb the flag through and let either switch turn the listing off. * filer: count a proxied chunk request once Moving the dispatch below the gate put it after the deferred request observation, so every proxied chunk now landed in FilerRequestHistogram twice, once under its HTTP method and once under chunkProxy. Name the deferred one after the proxy instead, the way the unsupported-method branch already does, which also gives the endpoint the status codes FilerRequestCounter records. |

filer.remote.sync: skip an upload whose source entry was deleted or rewritten (#11149)
* filer.remote.sync: skip an upload whose source entry was deleted or rewritten A replay from an earlier offset (-timeAgo) re-emits create and update events for entries the filer has since deleted or rewritten. Their chunks are gone from the volume servers, so the upload can never succeed, and failing the event holds the sync offset before it: every restart of the subscription replays it into the same dead chunks, and progress on everything after it in the log is never persisted. One such entry stops replication for the whole mount. When the upload fails, look the entry up on the filer. Gone, or holding other content than the event described, the event is superseded and is skipped with an error log; the event that superseded it follows in the log and brings the remote to the current state. Otherwise the failure stands and the event is retried as before. Fixes #11148 * filer.remote.sync: compare chunks by file id when deciding an event is superseded filer.IsSameData compares chunk ETags, so a delete-and-recreate of identical bytes, which stores the same content under new file ids and drops the old ones, looked still as described and kept failing the event on its dead chunks. Compare by file id with DoMinusChunks, the way the filer itself decides which chunks an update leaves for deletion: the event is superseded when the current entry no longer references every chunk it named, and still as described when it does, including when more chunks were appended after it. * filer.remote.sync: ask the filer on the first failed upload attempt, not after the backoff The superseded check ran after util.Retry had given up, so every dead entry still cost the full retry cycle, about 13s, before it was skipped: the SDK reports a missing chunk as "RequestError", which IsTransientError takes as worth retrying. Move the check into the retry loop with util.RetryOnError. Any failed attempt asks the filer, and the loop stops at once when the entry is gone, surfacing errSuperseded for the caller to skip. An entry the filer still holds keeps the retry policy it had. filer.remote.gateway shares retriedWriteFile and the same offset-pinning processor, so its three call sites skip a superseded event the same way. |

filer: serve "//" paths at the cleaned path instead of redirecting (#11150)
* filer: serve "//" paths at the cleaned path instead of redirecting
http.ServeMux redirects a non-canonical path ("//", "..") to its cleaned
form, but since Go 1.22 it builds the Location from the already-escaped
path, so it is percent-encoded twice (golang/go#79897). A client that
follows the redirect re-posts "/负极全景" as "/%25E8%25B4%259F...", and
the filer stores a directory literally named "%E8%B4%9F...".
Wrap the filer muxes in CleanPathHandler, which rewrites the request to
the same cleaned path ServeMux would have redirected to and dispatches
directly. The decoded name reaches the handler, the round trip goes
away, and clients that do not follow redirects work too.
Fixes #11125
* filer: keep RequestURI in step with the cleaned path
PostHandler derives storage rules, the bucket and the read-only check from
r.RequestURI while writing the entry at r.URL.Path. After CleanPathHandler
rewrote only the URL, a "//" or ".." request would be placed by the raw
path and written to the cleaned one. Rewrite RequestURI too, as the
redirect-following client used to.
* filer: match storage rules on the decoded write path
PostHandler resolved the storage rule from r.RequestURI, the raw
request-target. Clients percent-encode non-ASCII segments on the wire, so
a read-only or TTL rule configured on "/data/只读/" never matched a POST
to "/data/%E5%8F%AA%E8%AF%BB/" and the write went through. Use r.URL.Path,
the decoded path the entry is actually written to, as the header-based
destination check already does. The query string no longer reaches the
rule lookup, so the "?" trimming in the read-only error is gone.

filer.remote.sync: confirm a missing RemoteEntry against the filer before re-uploading (#11146)
* filer.remote.sync: confirm a missing RemoteEntry against the filer before re-uploading The event is the entry as it was when the update was logged. A chmod or utimes right after a write is logged while the sync is still uploading the write, so it carries no RemoteEntry even though the object is on the remote by the time it is processed. Gating on the event alone turned every such update into a delete and a second upload of the same bytes; cp -p, rsync and Django's FileSystemStorage all write that way. Look up the filer's current entry when the event has no RemoteEntry: the upload stamps it as soon as it completes, so the stamp is there for the race and absent for a file that was never replicated. Skip the update when the entry has since been deleted rather than upload from chunks that may be gone; the delete event that follows removes the remote object. Tests build entries from chunks, which is what IsSameData compares in production, and cover both no-RemoteEntry cases through a stub filer. Generated with [Devin](https://devin.ai) Co-Authored-By: Devin <158243242+devin-ai-integration[bot]@users.noreply.github.com> * filer.remote.sync: do not delete the remote object before overwriting it in place The update write path deleted the old object and then wrote the new one, even when both are the same key. S3, GCS and Azure all overwrite on write, so the delete bought nothing and left the remote with no object between the two calls, or at all if the write then failed and pinned the offset. On a versioned remote bucket it also left a delete marker per rewrite. Delete only when the key changes, which is what the delete was for.

filer.remote.sync: upload files that were never replicated (#11140)
An entry whose content is rewritten unchanged before it first reached the remote took the metadata-only branch, and UpdateFileMetadata returns early when the extended attributes match without checking that the object is there. shouldSendToRemote had already reported the entry as needing to be sent, so the effect was that it stayed local for as long as its content did not change, with the sync reporting healthy progress over it. Require RemoteEntry to be set before treating an update as metadata-only. Gating at the caller covers the S3, GCS and Azure clients, which share the same early return. Fixes #11139 |

Remove the RDMA sidecar prototype and its mount client (#11119)
* rdma: drop the sidecar prototype The Rust engine under it never touched a wire: rdma.rs fabricates pattern bytes and the crate's default feature is mock-ucx, with real-ucx unimplemented since the directory landed. Nothing builds it, no CI runs it, and its only consumer is weed mount's RDMA client, removed next. Two 22MB binaries were committed along with it. Claude-Session: https://claude.ai/code/session_01X3zhqLYwQwEQCrRbuzQKvy * mount: remove the RDMA client that spoke to the deleted sidecar Its only server was the sidecar's HTTP API, and the path could never have worked in production anyway: it served a single chunk per call, ignored the buffer's chunk boundaries, and had no test. Removing it also removes the per-handle cumulative-offset cache, which nothing else used. The -rdma.* mount flags go with it. They defaulted to off and pointed at an address no released build ever listened on. Claude-Session: https://claude.ai/code/session_01X3zhqLYwQwEQCrRbuzQKvy |

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.

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 |

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 |

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 |

ec: uniform shard block layout (#10932)
* ec: uniform shard block layout An EC volume is striped as 1GiB blocks until less than one row remains, then 1MiB blocks, and consecutive blocks land on different shards. With ec.encode's -fullPercent 95 against the 30GiB default limit, ~30% of every volume sits in that 1MiB tail, so a 4MB filer chunk there is five stripes on five servers. New encodes now use one block per shard, sized ceil(datSize/dataShards) rounded up to 1MiB and recorded in the .vif (EcShardConfig.block_size, also carried by the .ecsum manifest). A needle now maps to one shard unless it is larger than the block or straddles a boundary. The chosen size equals the legacy layout's padded shard length for every input, so shard sizes, capacity math, and the shard-size credibility checks are unchanged; only the byte placement moved. Reads, decode, and scrub resolve the block sizes from the volume's .vif; absence keeps the legacy interpretation, so existing EC volumes read exactly as before. Rebuild is layout-agnostic. weed fix -ecx recovers the layout from the .vif, else the .ecsum sidecar, and with neither de-stripes under both candidate layouts and keeps the one that indexes more valid needles. Same change in the Rust volume server, which now also streams the encode in 256KB sub-batches like Go instead of allocating whole blocks, and computes the large-row count as shardSize/largeBlock to match Go on exact multiples. On a 26MB fixture both encoders produce byte-identical shards, and a Go-written .vif parses in Rust with the block size intact. * ec: resolve the rust ecx rebuild through the recorded layout The Rust rebuild path regenerated a lost .ecx by scanning the logical .dat through a hand-rolled pure-1MiB striping, which was already wrong for legacy volumes with large-block rows and is wrong for any uniform volume with a block past 1MiB. Route the scan through locate_data with the .vif-recorded block size, the same mapping the read path uses. Also seed the new tests' random data instead of the deprecated global math/rand.Read. * ec: fail the Rust ecx rebuild on any shard read error A read error mid-scan published the entries collected so far as a successful .ecx, and read_at's byte count was ignored so a legal short read passed as complete — a truncated or failing shard could produce a silently incomplete recovery index. Exact-read semantics in read_from_data_shards, error propagation in the needle walk, and a truncated-shard regression test. * ec: fail the mount on an unreadable or malformed vif Both servers silently fell back to the legacy layout when an existing .vif could not be read or parsed. Every new encode records a positive uniform block size there, so the fallback mounted the same shards with legacy offset math and could return wrong data. Absent stays legal (legacy volumes predate the sidecar), and a zero-byte stub still reads as absent (Go's MaybeLoadVolumeInfo convention, now mirrored in Rust); a present-but-unreadable or malformed .vif fails the mount instead. * ec: bound the reconstruct fan-out of one needle's intervals A degraded interval fans out a read to every reachable shard location, each with a buffer the size of the interval. Reading a needle's intervals in parallel multiplied that by the interval concurrency: a needle spanning 8 blocks could hold 8 x MaxShardCount remote reads and buffers at once, where the sequential version peaked at MaxShardCount. Give each needle a single reconstruct budget its intervals share, held for the buffer's lifetime, so separate reads stay independent but one read cannot multiply its own fan-out. * ec: drop the duplicated shard-size formula calculateExpectedShardSize reimplemented the padding rule that UniformBlockSize already owns — TestUniformBlockSizeMatchesLegacyShardSize asserts the two agree for every input — so a change to the rule would have had to be made in both. Defer to the helper, keeping the historic answer for an empty .dat. * ec: resolve the shard block layout from whatever records it Four places still answered the layout question by inference when a record of it was available, or accepted an answer that was not one: - A mount with no .vif defaulted to the legacy layout; the bitrot sidecar records the same config at encode time, so take it when present, as weed fix -ecx already does. The vif itself is now parsed once per mount rather than twice. - The Rust ecx rebuild derived its row count from the padded shard extent, which under the legacy layout reads a shard that is an exact large-block multiple as one row too many. Pass the encode-time .dat size from the .vif and keep the extent as the fallback. - weed fix -ecx read the block size outside the EC-config guard (collapsing the unknown sentinel into a definitive legacy), only wrote the recovered layout back when the .vif was absent rather than unusable, and broke a scan tie by candidate order instead of the documented reach. - The uniform layout tripped writeDatFile's large-block ambiguity guard, which cannot apply when the large and small blocks are the same size. * ec: give the index-recovery tests a parseable vif The fixtures wrote the literal bytes "volinfo" as the source .vif and the recovery copies it verbatim, so the receiving server then mounted the volume from a .vif it could not parse. That used to pass by silently defaulting to the legacy layout; a mount now refuses a vif it cannot read, which is what the tests were exercising all along without meaning to. * ec: validate the layout a vif records, not just its syntax Review follow-ups on the mount-strictness change: - A .vif can parse and still record a block size no encoder could have produced (negative, or not a whole number of small blocks). Both servers took it and mapped every read through it. ValidateBlockSize / the Rust mirror now refuse the mount, the same way an unparseable vif does; 0 stays valid as the legacy two-tier layout. - The bitrot-sidecar fallback accepted parity_shards == 0 and summed the counts in their own width, so values near the ceiling wrapped past the MaxShardCount bound. Require both counts and sum in a wider type. - weed fix -ecx treated a config with only DataShards > 0 as usable, so a half-written .vif suppressed the recovery paths AND survived the rewrite. Require a complete, in-range config before trusting it. - Returning the vif-load error left the .ecx and .ecj descriptors open; repeated mount attempts on malformed metadata could exhaust them. * ec: refuse to act on a layout the metadata does not establish - The worker encode only logged a failed .vif write and skipped it in the distribution set, and treated the .ecsum write as best-effort. A worker whose disk filled after the much larger shards landed could still distribute, mount, verify shard inventory, and delete the source replicas — leaving holders with shards whose geometry nothing records. Both writes and both inclusions are encode success conditions now. - A generation-matching .ecsum that disagreed with the .vif geometry only disabled checksums in Go, and in Rust was not compared at all, so protection stayed On while reads used the other layout. Both files record the layout their generation was encoded with, so a disagreement now fails the mount. * ec: reject an invalid recorded block size in weed fix -ecx A .vif with valid shard counts but a negative or unaligned block size was marked usable: a positive invalid value pinned the scan to a geometry that de-stripes to garbage, and a negative one ran the dual scan but left the invalid .vif in place afterwards. Validate it with the same rule the mount applies, and when it fails leave the layout unknown so the scan recovers it and the file is rewritten. * ec: validate the sidecar layout weed fix -ecx recovers from The .ecsum fallback was taken on DataShards > 0 alone, so a CRC-valid sidecar carrying the wrong generation, an incomplete ratio, or an unaligned block size would pin the reconstruction to one incorrect uniform-layout candidate instead of letting the dual scan decide. Require generation 0, a complete in-range ratio, and a valid block size; anything less leaves the layout unknown, which is the answer that still recovers by scanning. * ec: let only a genuinely absent sidecar choose the legacy layout With no .vif the bitrot sidecar is the only record of a volume's layout, and the mount fallback read a failed load, an unusable config, or a sidecar stamped for another generation as "assume legacy". A uniform generation-0 volume could therefore mount with legacy or another generation's geometry and answer reads with the wrong bytes. Present-but-unusable now fails the mount; only actual absence keeps the legacy defaults. Shared as EcShardConfigFromSidecar so every caller reads the sidecar the same way. * ec: treat a recorded-but-impossible layout as corruption, not as legacy - A .vif whose ecShardConfig is PRESENT but records an impossible ratio was answered with the default 10+4 and the legacy block layout, in both languages. That reads a uniform volume's shards at the wrong offsets and returns the wrong bytes. Only an entirely absent config still means "this predates the record"; a present one that cannot be true fails the mount. - The shard-count bound summed two uint32 counts as int, which wraps on a 32-bit build: 0x7fffffff + 0x7fffffff lands at -2 and slips under MaxShardCount. ValidEcShardCounts sums in uint64, and every EC call site that checked a recorded ratio now goes through it. * ec: rebuild on the geometry the sidecar records, and flag it when it disagrees The rebuild RPC passes BackgroundECContext, so RebuildEcFiles resolves the layout itself — and it resolved a missing or invalid .vif to the default 10+4 with the legacy block size. Two consequences: a 12+4 volume was reconstructed through a 10+4 matrix, which produces wrong bytes and never regenerates shards 14-15; and the chosen geometry then contradicted a valid uniform sidecar, which loadRebuildSidecar reported as BitrotOff — silently skipping the input and regenerated-shard checksum checks precisely when the volume had already lost its metadata. The layout now resolves from the bitrot sidecar (found across the server's disks, not just beside the base name) before falling back to the defaults, and a present-but-impossible ratio fails instead of being replaced. A sidecar that contradicts the chosen geometry is BitrotInvalid, which the existing unsafeIgnoreSidecar override still lets an operator push past. * ec: let the Rust rebuild read metadata off a sibling disk read_ec_shard_config searches only the location the rebuild writes into, so a volume whose .vif or generation-0 .ecsum sits on another of the server's disks resolved to the default 10+4 with the legacy block layout — the Rust half of the geometry-guessing the Go rebuild just stopped doing. It then reconstructs a custom-ratio or uniform volume through the wrong Reed-Solomon matrix and de-striping geometry. The rebuild now looks for the .vif in its own location and then each sibling, falls back to the generation-0 sidecar wherever that lives, and only defaults when neither exists anywhere. The encode-time .dat size the ecx rebuild needs is resolved the same way. * ec: resolve a rebuild's vif from every directory that may hold it RebuildEcFiles probed only <data-base>.vif. The caller knows the selected location's index directory and the sibling locations, but passed neither for metadata: additionalDirs carried shard directories only, and were searched for shards and the checksum sidecar. A split -dir/-dir.idx layout, or a disk holding only shards, therefore resolved a pre-sidecar custom-ratio volume to 10+4 and reconstructed through the wrong matrix — never regenerating shards 14-15. The caller now hands over the index and sibling directories, and the resolver probes the vif across all of them, matching what the Rust resolver already does for both the vif and the sidecar. * ec: make every rebuild consumer agree on the layout it resolved - The post-rebuild bitrot backfill re-derived the geometry from this directory's .vif alone and dropped the block size entirely, so a rebuild that resolved its layout from a sibling, the sidecar, or a uniform vif wrote a manifest describing a DIFFERENT layout — one later mounts reject, or that covers only the default shard count. The layout is resolved once now, through an exported ResolveRebuildECContext, and the rebuild and the backfill share that answer. - The Rust rebuild collected only each location's data directory, so a sibling's INDEX directory — where a split -dir/-dir.idx layout keeps .ecx/.ecj/.vif — was never probed, and a custom-ratio volume still resolved to 10+4 with the legacy layout. Both directories of every location are carried now, deduped against the rebuild's own. - A shard delivery can bring the checksum manifest with it, but the receive path only writes the file: a server that already had the volume mounted kept its resolved protection state (off) until a remount. The mount RPC re-resolves it once the shards it describes have been added. * ec: cover the rebuild's directory search with tests Reviewers flagged the sibling index directory twice, and the fix that closed it had no test of its own: the assembly sat inline in the rebuild handler, reachable only through a gRPC call against a populated store. Lifting it into rebuildSearchDirs / select_rebuild_location makes the rule assertable — a sibling contributes BOTH its data and its index directory, a shared index directory is listed once, and the rebuild's own data directory never repeats. Writing the Rust cases surfaced that the two implementations do not agree on where the rebuild's own index directory belongs, and both are right: Go's resolver takes a single directory list, so that directory has to be inside it, while Rust's takes the rebuild's data and index directories as their own arguments and would search them twice. The tests now state which contract each side is holding to, so neither drifts into the other's shape. Pure refactor otherwise; no behaviour change. * ec: search the index directory for the layout sidecar The Rust resolver looked for the generation-0 .ecsum in the rebuild's data directory and the sibling list, but not in the rebuild's own index directory — while the .vif lookup directly above it did, and Go's findBitrotSidecar has always checked both bases. On a split -dir/-dir.idx location that directory is where the metadata lives, and callers leave it out of the sibling list precisely because it is passed here separately, so nothing searched it. With no .vif anywhere the sidecar is the only surviving record of the layout. Missing it resolved a 12+4 uniform volume to 10+4 with the legacy striping — the test added here fails with (10, 4, 0) against the old code — and the rebuild then reconstructs through the wrong matrix and writes .ecx offsets that no reader can follow. * ec: let the rebuild see its own index directory The Rust rebuild takes a single flat directory list — the shape Go's RebuildEcFiles uses — so it cannot be handed the rebuild location's index directory separately the way the layout resolvers are, and the handler was passing the sibling list, which deliberately omits exactly that directory. On a split -dir/-dir.idx location that is where .ecx and .vif live, so the shard and index lookups could not see them. Go has always carried that directory in additionalDirs; this lines the two call sites up. * ec: let a config-free vif fall through to the layout sidecar A .vif that carries no ecShardConfig answers nothing about the layout, so it is no more informative than an absent one — but both trees treated its mere existence as the end of the search. Go went straight to the 10+4 legacy defaults without consulting the sidecar at all; Rust returned whatever ec_shard_config_from could make of a single directory. A 12+4 uniform volume with a legacy config-free vif therefore resolved as 10+4 legacy, and every read landed at the wrong shard offset. The sidecar lookup was also single-directory on both sides, while a split -dir/-dir.idx layout keeps .vif and .ecsum with the INDEX. Go's findBitrotSidecar has always taken both bases; the callers here passed only the data base, and the Rust bitrot resolver derived its path from the data base alone. Rust's layout resolver now takes a candidate directory list — data, index, then any siblings — and searches all of it, which also removes the early return that made the vif's presence decisive. load_vif_info_across_dirs reported `dir` even when load_vif_info had found the vif in `dir_idx`. Nothing reads that field today, so this changes no behaviour; it stops the next caller that resolves the rest of the volume's metadata against the answer from being sent to a disk holding none of it. Absence stays legal throughout: a volume with neither record is genuinely legacy. Present-but-unusable still fails the mount, now in the config-free-vif branch too. * ec: activate a delivered sidecar on every per-disk runtime A vid mounts as one EcVolume per disk, each with its own resolved protection state, but the post-delivery reload used the first-match lookup and so touched exactly one of them. The siblings kept reporting no protection until a remount — and since shard distribution deduplicates the metadata files onto the first target disk for a node, the runtime that got the .ecsum is not necessarily the one the lookup returns. Iterate every runtime instead, via a new FindAllEcVolumes and its Rust mut equivalent. Combined with each runtime now resolving its sidecar against its index directory as well as its data directory, a server sharing one -dir.idx across its disks activates all of them from the single delivered copy. The Rust volume server had no post-mount reload at all; it gets one here, matching Go. * ec: resolve the delivered sidecar across every EC metadata directory Reloading every per-disk runtime, added last round, did not by itself make the delivered manifest reachable. Startup mirroring copies .ecx/.ecj/.vif to every shard-bearing disk so each mounts self-contained, but deliberately not .ecsum, and a repair delivers exactly one copy. Each runtime was resolving against its own two directories, so every sibling of the disk that received the file kept reporting no protection however often it reloaded. Resolve one authoritative copy across every EC metadata directory instead of duplicating the file. Mirroring .ecsum would have to keep pace with a file that is rewritten as shards are repaired, and would not help the reported case at all: the delivery happens at runtime, and mirroring only runs at startup. The regression test pins both halves — a reload restricted to the volume's own directories still finds nothing, and the same reload given the server's metadata directories turns protection on. * ec: ask every directory before writing a TOFU baseline After a rebuild the opportunistic backfill asks whether this volume already has a checksum manifest, and answered from the data base alone. A split -dir/-dir.idx layout keeps the sidecar with the index, and a multi-disk server may keep it on a sibling, so an existing manifest read as absent. The consequence is worse than a missed read. On a false "no" the backfill writes a fresh sidecar at the data base from whatever the shards say right now — and the data base is the first candidate every resolver checks, so that TOFU baseline shadows the real manifest rather than sitting beside it. A shard that was silently corrupt gets blessed, and the record that would have caught it stops being consulted. FindBitrotSidecar exports the search the package already used internally, so the question is asked of the data base, the index base and the sibling disks — the same candidates the rebuild resolves its layout from. * ec: refuse a shard block size no encoder could have produced weed fix -ecx derived one from the raw shard extent, so a truncated or partially copied shard wrote a .vif that NewEcVolume then permanently refuses — the volume the tool was run to rescue could never mount again. An extent that is not a whole number of small blocks cannot have come from a uniform encode, so it is no longer offered as a candidate, and nothing unvalidated reaches the .vif. Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7 * ec: derive the .vif's dat size and block size from one measurement VolumeEcShardsGenerate stat'ed the .dat before the encode while WriteEcFiles stat'ed it again to size the blocks. A write landing between the two produced a .vif whose own two fields describe different files. WriteEcFiles now leaves both on the context, and fills a placeholder context in place so the caller can read them back. Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7 * ec: keep the source volume until every holder serves its shard layout The uniform layout rides in a .vif field older volume servers never knew: they discard it, mount the shards as legacy and return wrong bytes with nothing erroring, and the shard files are the same length either way so no other check notices. The upgrade order lived only in the release note. VolumeEcShardsInfo now reports the block size the holder actually serves, in both the Go and Rust servers, and the pre-delete verification refuses to drop the source unless every reachable holder echoes the one the shards were encoded with — while a rollback still exists. A server that predates the field answers 0, which is the negative answer. Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7 * ec: drop the rebuild's dead block-size parameters generateMissingEcFiles never reads largeBlockSize/smallBlockSize — Reed-Solomon reconstruction is layout-agnostic — so passing the legacy constants only advertised a layout the rebuild does not use. Also move UniformBlockSize's doc off ValidateBlockSize. Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7 * ec: warn about EC defaults only when the mount used them The "vif file not found, using defaults" warning fired even after the bitrot sidecar supplied a non-default layout, sending anyone triaging wrong bytes after the legacy layout the volume never mounted on. Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7 * ec: stat the distributed bitrot sidecar once The strict check re-stat'ed the file immediately before the stat that already gates inclusion, and a failed sidecar write now fails the encode outright, so the first could only fire on a deletion between the two lines. Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7 * ec: say what the reconstruct budget actually bounds A shard's buffer stays in bufs until its interval reconstructs, which is after the read that filled it released its permit, so the semaphore bounds round trips in flight and not retained bytes. Peak memory is the intervals reconstructing at once times the shards each reaches times the interval size. Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7 * test: let the fake volume server report its delivered EC layout The pre-delete verification now asks each holder which shard block layout it serves, and a fake that always answered "unset" looked exactly like a volume server too old to know the field. Distribution ships the .vif to every holder alongside its shards, so read the layout back out of it as a real holder does. Claude-Session: https://claude.ai/code/session_011FRRoNKBiGbH58rs2AQyA7 |

volume: resolve the disk IO slow-latency threshold per disk (#10976)
* volume: resolve the disk IO slow-latency threshold per disk volume.toml keys [volume.disk.io.slow.latency] by disk type, but the threshold was chosen once per server by switching on the raw -disk flag. -disk is comma-separated, one entry per -dir, so a multi-disk server matched no case and silently took the hdd threshold. Carry the table on DiskIOProbeConfig and resolve it in CheckDiskSpace from the location's own DiskType. A type with no entry keeps falling back to the hdd threshold. * volume: run the disk IO probe on multi-directory volume servers The probe was disabled whenever more than one -dir was configured, because a single server-wide slow-latency threshold could not describe disks of different types. The threshold is per disk now, and the rest of the probe already is: diskRegistry is keyed by directory, each DiskLocation runs its own CheckDiskSpace, and Store consults isDiskUnavailable per location. * volume: reject duplicate -dir entries Nothing deduplicated -dir, so the same directory listed twice produced two DiskLocations that each loaded every volume in it, appending to the same .dat under two independent locks. Compare directory identity with os.SameFile rather than the path, so a symlink or bind mount aliasing an earlier entry is rejected as well. * volume: cover the per-disk slow-latency handoff SlowLatencyFor has a test, but nothing asserted that CheckDiskSpace feeds it the location's own disk type. Probe through a seam so the resolved threshold is observable, and check hdd, ssd, nvme, the empty type, and an unlisted tag. |

s3: keep verifying the request host when externalUrl is set (#10970)
* s3: keep verifying the request host when externalUrl is set externalUrl was the only host candidate once set, so a client that dialed the gateway directly instead of through the proxy always got SignatureDoesNotMatch. Make it lead the candidate walk instead: every candidate still needs a valid signature, and the request-derived hosts are already trusted when the flag is unset, so a mixed proxy plus in-cluster topology can now advertise a public endpoint and verify both planes. * s3: cover virtual-hosted addressing behind externalUrl The old pin also rejected an external client that signed bucket.api.example.com, since only the bare externalUrl host was ever tried. The candidate walk covers it; pin the case down. |

* mount: name the disk after the mounted path Finder and Explorer labelled every mount with the filer address, so two mounts from one filer were indistinguishable. Use the mounted path's last segment, the way df already shows it, and keep the filer address only for a whole-tree mount. * mount: let a given mount option override the default The options from -o were placed before the ones this mount derives, so a volname or iosize given on the command line lost to the derived value.

admin: accept a list of collections in the task collection filter (#10953)
The collection filter was parsed twice with two syntaxes: the master-side volume listing compiled the whole string as one regex, while EC encode and EC balance detection split it on commas and matched each entry as a wildcard. A volume had to pass both, so "collection-a,collection-b" matched nothing (no collection is named that), and the ALL_COLLECTIONS sentinel, which the master side skips, dropped every volume at the task side. Parse it once, in one place: a comma-separated list where an entry is a name with optional * and ? wildcards, or a regex when it carries regex syntax. A regex entry now has to match the whole name unless it anchors itself, so listing a collection no longer picks up its longer namesakes. |

mount: register UNC mount points as WinFsp network file systems (#10943)
A \\server\share -dir was passed to WinFsp as a plain mount point, which treats it as a directory path on an actual remote server and fails. Turn it into the VolumePrefix option instead, so the mount registers with the WinFsp network provider: the UNC path is then reachable from every logon session, which a drive letter mounted from a service is not, and each user can map their own drive letter to it. |

filer.backup, filer.sync: stop sharing resume checkpoints across destinations (#10934)
* filer.backup: key the checkpoint by source path and sink destination The checkpoint id hashed only sink name + directory, so two backups to different buckets or endpoints sharing a directory layout advanced one checkpoint: whichever job was running pushed the shared offset forward, and a stopped or failing job later resumed from the other's position, silently skipping changes. Backups of different source paths to the same destination shared a checkpoint the same way. Each sink now reports a destination identity (endpoint or account, bucket or container, directory) and the checkpoint is keyed by the source path plus that identity. Reads fall back to the historical name+directory key when the new key has no value, so existing backups resume where they left off; writes go only to the new key. * filer.sync: include the target path in the offset key The offset stored on the target filer was keyed by source path and source filer signature only, so two syncs from the same source cluster and path to different directories on the same target cluster advanced one shared checkpoint, and the slower one could resume past events it never applied. The target path now participates in the key; "/" keeps the historical form, and a sync with a non-root target path falls back to the historical key once when its own key has no value yet. * join checkpoint key fields with NUL so they cannot alias A path or configuration value spelling out the separator could concatenate two different field tuples to the same checkpoint key. NUL cannot appear in a CLI path argument or any sane configuration value, making the encoding injective. |

mini: reserve the admin gRPC port instead of binding it late (#10928)
* mini: reserve the admin gRPC port instead of binding it late Port selection probes every port with a throwaway listener and closes it. Master, filer, volume and S3 bind a moment later, but the admin waits for all of them first and only then binds its worker gRPC port, roughly two seconds in. That port defaults to the admin http port + 10000, which lands inside the Linux ephemeral range, so one of the cluster's own outgoing gRPC dials can take it during the gap and the admin dies on bind, taking the worker with it. Keep the listener from the availability check and hand it to the admin. * mini: clear the admin gRPC reservation before retaking it A rerun inside one process would otherwise inherit the closed listener of the previous run whenever the reservation fails, and the admin would accept it and only find out inside Serve. * mini: snapshot the admin options for the startup goroutine The cleanup path read the package-level options long after the goroutine started, so a later in-process run could have its reserved listener closed by the previous run. |

admin: honor a persisted or admin.toml maintenance enabled=false (#10909)
* admin: honor a persisted or admin.toml maintenance enabled=false The startup path discarded an operator's enabled=false twice over: ApplyDefaultsToProtobuf treated the bool zero value as unset and applied the schema default of true, and a force-enable migration block flipped any survivor. With the legacy /maintenance UI routes gone, nothing could write the config either, so the maintenance system ran unconditionally. Keep the persisted enabled flag across schema-default application in LoadMaintenanceConfig, drop the force-enable block, and add a top-level [maintenance] enabled key to admin.toml as the config surface, persisted through SaveMaintenanceConfig like the per-task settings. Absent config still defaults to enabled. * admin: track presence on the maintenance enabled flag A plain proto3 bool cannot distinguish an operator's persisted false from a legacy file that simply omits the field, so honoring false would have silently switched maintenance off for configs written before the toggle could be persisted. Make the field optional: files that predate presence tracking keep the enabled default, while a file that explicitly persists the toggle is honored either way. |

master: never re-seed a raft cluster over committed state under -raftBootstrap (#10883)
* master: never re-seed a raft cluster over committed state -raftBootstrap deleted logs.dat, stable.dat and snapshots on every start and then bootstrapped a fresh cluster. Since hashicorp raft only snapshots after 8192 log entries, the TopologyId lives in the log, not in a snapshot, so the pre-wipe snapshot recovery found nothing and each restart minted a new cluster identity. A master that came up while it could not reach its peers seeded a rival cluster; when the two logs met, SetTopologyId's split-brain guard fatally stopped every master holding the other id, and the master layer crash-looped with no quorum. Bootstrapping is genesis. Drop the wipe and the inline bootstrap. The first master in -peers already mints a cluster once it has confirmed no peer has a leader, so the flag has nothing left to do and is now ignored; keeping that one master the sole bootstrap authority is what stops a partition from minting two clusters, so the flag must not widen it either. A master with state rejoins its peers, and one whose data dir was reset is admitted by the sitting leader instead of forking again. * test: cover -raftBootstrap restarts in the multi-master suite Three masters start with -raftBootstrap, the way the helm chart renders it on every master on every roll, and the cluster has to hold one TopologyId after they all restart. /dir/status is proxied to the leader, so each master's own view of the identity is read out of its log, which is where a fork shows up. Before the fix the hashicorp case minted a new id on each restart. |

master: let the leader admit a master that starts with no raft state (#10865)
* master: answer with the leader raft already knows Topo.Leader() backs off for up to 20 seconds waiting for an election. Callers that a health probe or a client is blocked on cannot afford that: /cluster/status, /cluster/healthz and /readyz all sit past the probe timeout of both the helm chart and the operator, so a master that is still joining looks dead rather than joining, and the kubelet restarts it. informNewLeader and SendHeartbeat hold the client on a master that cannot serve it, exactly when it should move on to find the one that can. Answer these from MaybeLeader instead, which reports what raft knows right now. MaybeLeader takes over the "am I the leader myself" fallback that Leader() used to apply on top of it, so one non-blocking call is still correct; Leader() keeps the backoff for callers that must wait. * master: let the leader admit a master that starts with no raft state Neither raft implementation lets a server outside the configuration campaign: goraft's promotable() requires a non-empty log, and hashicorp rejects vote requests from a candidate that is not in its configuration. A master that comes up with fresh state therefore cannot elect itself in — the leader has to pull it in. Nothing did. The peer list is static, rendered from the replica count, so scaling it up leaves the sitting leader running the old list with no idea the new masters exist. Under goraft they wait forever. Under hashicorp they are worse off: each bootstraps a cluster of its own from the new list, and two of them form a quorum next to the live leader, with their own TopologyId. That is the split brain SetTopologyId kills a master over. Admit the peer where it registers instead. Only the leader gets past the IsLeader check in KeepConnected, and a joining master's client lands there, so that is the moment it joins. The broadcast OnPeerUpdate rides on is not enough on its own: it only reaches masters already connected, which is why a leader that came up first missed both newcomers. RaftAddServer grew a goraft branch on the way, so cluster.raft.add stops silently doing nothing on the default raft, and RaftRemoveServer with it. Bootstrapping is now one call for both implementations, made only after the peers confirm nobody has a leader, and retried until this master is in rather than checked once and dropped. * master: do not evict a peer that is still in -peers The hashicorp leader drops a master from the raft configuration as soon as it stops answering pings. A master that is merely restarting answers nothing, so an ordinary bounce shrinks the quorum behind the operator's back — and then races its own return: the master comes back, registers, gets re-admitted, and the eviction lands after it. A randomized start/stop walk lands on it. Two of three masters running, the leader evicts the one that just went down, the restart re-adds it, the removal commits late and takes the leader's own leadership with it. What is left is a two-server configuration whose other half is down, and a running master that nobody will ask for a vote — no quorum, no way back until the third master returns. -peers is what declares membership. updatePeers already reconciles the configuration against it on every leadership change, and an operator who really means to drop a master can say so with cluster.raft.remove, so keep the eviction for masters that are no longer listed at all. * test: bounce masters at random and hold the election to it Twelve rounds of stopping or starting a random master, on both raft implementations, checking the two things an election must never get wrong: two masters claiming leadership at once, and a quorum that comes back without agreeing on one. The cluster's identity has to survive the whole walk, since a master that re-mints a TopologyId is the split brain SetTopologyId kills its peers over. The seed is random and logged, so a failure names the walk that reproduces it. Below a quorum the walk moves straight on. A master that has lost its quorum cannot commit anything, and goraft only checks whether it still has one on an election-timeout ticker, after its peers have been quiet for a full timeout — measured taking over 30 seconds to step down. That direction belongs to TestTwoMastersDownAndRestart, which was giving it ten seconds and would have started failing on a slower machine; it now waits on that behaviour explicitly rather than sleeping twice and hoping. WaitForTopologyId returns the id it waited for. Reading it separately raced the leader applying the raft entry that carries it, which shows up as an empty id right after an election rather than as a wrong one. |

mini: state the format of a -tableBucket, do not infer it (#10851)
* mini: state the format of a -tableBucket, do not infer it
A table bucket holds one format and that format decides which catalog can
serve it, but the flag only took names. The format came from
miniTableBucketFormat(): Iceberg whenever its port was up, Lance only when
it was not. So -tableBucket=vectors on a default mini quietly made an
ICEBERG bucket that the Lance namespace then refused every table in, and
the only way to get a Lance one was -s3.port.iceberg=0, which buys it by
deleting the other catalog. One flag, two meanings, decided by an unrelated
port.
Each entry is now name[:FORMAT], unsuffixed meaning ICEBERG as before:
weed mini -tableBucket=warehouse,vectors:LANCE
Both catalogs stay up and both buckets are reachable. A name whose format
has no endpoint here is skipped with a warning rather than created out of
reach, and the Iceberg-only S3_TABLE_BUCKET default-routing hint gets the
Iceberg names alone, without their suffixes.
* mini: do not reuse a table bucket that holds another format
CreateTableBucket answers BucketAlreadyExists on the name alone, so
-tableBucket=vectors against a bucket created as LANCE logged "already
exists" and moved on, and the Iceberg default-warehouse hint then pointed
at it. Every table create against that catalog fails with "table bucket
vectors holds LANCE tables", far from the flag that chose it.
ensureMiniTableBuckets now reads the format of a bucket it did not create,
warns when it is not the one asked for, and returns only the buckets that
hold what was requested. S3_TABLE_BUCKET is seeded from that list, so an
unprefixed Iceberg request falls back to its own default rather than
committing into a Lance bucket. A bucket predating declared formats reports
an empty one and still accepts either.
* mini: normalize S3_TABLE_BUCKET whichever way the spec arrived
The rewrite that keeps Lance names out of the Iceberg default warehouse only
ran when the flag supplied the spec. Set the variable directly, as the docker
quickstart does, and it reached the catalog untouched: S3_TABLE_BUCKET=
vectors:LANCE,warehouse made the unprefixed default the literal string
"vectors:LANCE", a bucket no lookup finds, while warehouse sat behind it.
The variable is both mini's input and the catalog's routing hint, so it is
now always rewritten from the buckets that came back holding Iceberg tables,
and unset when there are none rather than left pointing somewhere stale.
* mini: reuse a table bucket only when its format reads back
An ordinary S3 bucket wearing the name answers CreateTableBucket with the
same BucketAlreadyExists as a table bucket does, and the format lookup that
follows returned "" for a failed read exactly as it does for a bucket
predating declared formats. So -bucket=data -tableBucket=data reported
nothing and published data as the Iceberg default warehouse, where every
unprefixed request 404s on a bucket that is not a catalog.
The lookup now returns its error, and only a bucket that reads back as the
format asked for is reused. Anything else is left alone with a warning
naming why, rather than routed to and discovered later.

Lance catalog, and a Rust plugin worker to maintain it (#10841)
* iceberg: skip tables the maintenance worker does not own A Lance dataset registered through the Lance namespace's Iceberg REST adapter arrives as an Iceberg table with a placeholder schema and table_type=lance, and keeps its fragments under data/ - the same subdirectory the orphan cleaner walks. Every fragment is unreferenced by the Iceberg metadata, so a maintenance pass deletes the dataset. Views share the entry shape and were only skipped because parsing their metadata happened to fail first. Gate the scan and the execution path on the entry actually being an Iceberg table. Maintenance is off by default, so this was latent rather than live. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * s3tables: let a table declare a format the catalog does not interpret CreateTable accepted ICEBERG and nothing else. A Lance table has no metadata file for the catalog to maintain - the entry records a name and the dataset root, and the client owns everything under it - so accept LANCE, and carry the declared format on the entry instead of hardcoding it back on the way out. ListTables now reports format and metadataLocation, so listing a catalog that holds both kinds takes one pass rather than a GetTable per row. AWS omits both fields; adding them is additive. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * s3tables: move the in-memory filer into its own package The Lance namespace tests need the same harness, and copying it would leave two of them to keep in step. Extracted as it was, plus the two fidelity gaps that only surface once a paginating caller uses it: ListEntries ignored startFromFileName and limit, so a caller that paginates re-read the first page until it hit its own cap and reported the same entry over and over, and GetFilerConfiguration was missing, which CreateTableBucket needs to resolve the buckets directory. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance: serve the Lance Namespace REST spec A second catalog surface beside the Iceberg one, over the same table buckets: the namespace and table metadata operations, the $-delimited identifier codec, the spec's numeric error model, the directory-catalog marker files, and storage_options vending through the STS path the Iceberg catalog already uses. Listens on -port.lance, 9101 by default, and inherits ARNs, policies and tags from the storage layer, so a Lance table needs no second permission model. Identifiers map bucket / namespace / table onto the three levels Lance clients already use, which is why there is no warehouse selector to invent. The data plane needs Lance format support that does not exist in Go and answers with the spec's Unsupported code rather than a bare 404. Two things it deliberately will not do: create a table bucket as a side effect of creating a namespace inside one, since a bucket carries its own policy and lifecycle, and resolve an Iceberg table's location for a Lance client, which would hand it a table another engine owns. The design note this follows is in design-lance-catalog.md, including the .lance directory suffix it proposed and this does not implement. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * mini: give the Lance port the same treatment as the Iceberg one The flag was registered but nothing else knew about it, so mini would start the server without reserving its port, waiting for it, or saying where it is. Adds it to the startup service list, the conflict resolver, the gRPC allocator's reserved set, the readiness wait, the stop reporting and the banner. The admin server still takes only the Iceberg port, because there is no Lance page for it to link to. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance: stop deregister and repoint from deleting the dataset Deregistering preserves data by definition, and this did the opposite: the catalog entry is the dataset directory, so DeleteTable took the files with it. Registering over an existing name had the same shape, destroying the dataset the name used to hold. Found by driving the running server rather than the in-memory filer, where both looked like success because the table did stop being listed. Deregistering is now a state on the entry - the marker file hides it, and declaring or registering the name again brings it back. Repointing a name at another dataset is an UpdateTable against the version token, so neither dataset loses files. Drop is left alone; it is the operation that does remove data. The storage endpoint now falls back to the advertised -ip where the Iceberg derivation gives up. An Iceberg client brings its own s3.endpoint and advertising the wrong one hijacks it, but storage_options is the only place a Lance client learns where the store is, and without it object_store quietly talks to real AWS. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * s3tables: refuse to create a table over one of another format Creating a table that already exists is idempotent, and that path returned the existing table without looking at its format. A Lance declare over an Iceberg table answered 200 and handed back a directory Iceberg owns, so the client would write its dataset on top. The view check immediately above it already guards the same class of collision. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * s3tables: let a table bucket hold a format other than Iceberg The S3 door validated every object written into a table bucket against Iceberg's file layout, so a Lance client could not write its dataset at all: it got 403 on data/*.lance, on _versions/, and on the _transactions/ directory it turned out to write as well. Table buckets were only neutral containers by intention; in practice they were Iceberg-shaped and enforced as such. The allowed set is now the union of what the supported formats write, because the validator runs where the table's format is not in hand. Underscore-prefixed directories are treated as belonging to the format, since enumerating them means guessing at the next one - _transactions is exactly the one this missed - and their contents are checked only for traversal. Iceberg writes none of them, so it loses nothing. Marker files at the table root are admitted too, which the namespace/table/dir/file shape had rejected as too shallow. Describe also honours the request-body spellings of with_table_uri, load_detailed_metadata and check_declared. The spec puts them in the query string, but real clients send both. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * design: record what the implementation found The table bucket being an Iceberg-shaped container, enforced at the S3 door, was the premise this design never questioned and the one that had to change before anything worked end to end. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * iceberg: prove the data loss the foreign-format guard prevents The guard landed with a unit test for the predicate and nothing showing what it saves. These seed what the Lance namespace's Iceberg REST adapter actually leaves behind - an Iceberg table with a placeholder schema and table_type=lance whose directory holds a Lance dataset - and assert both halves: orphan collection does flag the dataset's fragments, because the Iceberg metadata beside them references nothing, and the scan never reaches the table. An ordinary Iceberg table in the same shape is still scanned, so the guard is not just skipping everything. Confirmed against a running gateway first: our Iceberg catalog accepts the adapter's registration, and a real Lance client then writes a dataset into that table's location. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * s3tablestest: make the in-memory filer safe to race against Two gaps that only matter once a test drives concurrent writers, which is what an exclusive create has to be tested with: the entry map had no lock, and CreateEntry ignored O_EXCL entirely, so both writers of the same name would have won and the test would have passed while proving nothing. The BeforeUpdate hook runs before the lock is taken. Its whole purpose is to land a competing write in a handler's read-to-write window, and that write needs the lock the hook would otherwise be holding. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance: make the namespace an external manifest store Lance commits a version by writing _versions/{v}.manifest with put-if-not-exists. The S3 layer in front of this same filer evaluates If-None-Match by looking the entry up and then writing without a precondition, so two writers can both pass the check and one commit is lost. The filer itself has the primitive: CreateEntry with o_excl. Adds the four version operations a Lance client actually calls - create, list, describe and batch-delete - recording one entry per version under _lance_versions/, and advertises managed_versioning so the client routes its commits here. Reserving a version is the exclusive create, so exactly one of several racing writers wins and the rest rebase. Off by default, behind -lance.managedVersioning. Turning it on moves where a table's version history lives, and a reader that does not come through this namespace no longer sees all of it; that is the operator's call, not a default. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * design: record what managed versioning does and does not reach The first commit through a namespace-backed store works and is recorded the way the protocol specifies. Later commits do not, because lance 4.0.0 refuses put_if_exists on that path in its own code, so the feature is capped upstream rather than here. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * test: integration tests for the Lance namespace Everything this surface got wrong so far - a deregister that deleted the dataset, an S3 door that refused every Lance file, a version reservation that could not actually be exclusive - passed against an in-memory filer first. So these run against a live gateway, and where the claim is about data they check storage rather than visibility. Five Go tests on the shared harness: namespace and table lifecycle including that deregister keeps the bytes and drop removes them, that a Lance client cannot resolve or declare over an Iceberg table, that a Lance dataset's files get past the table-bucket layout guard while junk still does not, and that eight writers racing for one version produce exactly one winner. One Docker-gated test drives the real Lance client, which is the only way to check that the location and storage_options the namespace vends are between them enough to write and read a dataset. It overrides the endpoint with the container's view of the same gateway, because the shared harness binds a wildcard address and so vends none. The harness gains a Lance port and turns managed versioning on; the flag touches nothing outside that surface. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * s3tables: a directory with no namespace metadata is a missing namespace Three callers resolved a namespace by reading its metadata attribute and each tested only for a missing entry, so a directory that carried no metadata came back as an internal error saying "attribute not found". Creating a table under a namespace that does not exist answered 500. Collapses the three copies into one helper that reports both conditions as absent, which is what they are: a directory without namespace metadata is not a namespace. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * iceberg: stop reporting storage-layer refusals as server faults writeManagerError recognised a missing table bucket and sent everything else to 500, so a missing namespace, a duplicate name and a commit conflict all reached the client as InternalServerError with nothing to act on. Creating a table in a namespace that does not exist is the case that turned up: 500 where the spec wants 404 NoSuchNamespaceException. Maps the storage error types onto the exception names this package already uses, and keeps the existing bucket message, which explains how to select a table bucket. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * iceberg: skip a foreign-format table by name, not by failing to parse it A table the namespace created as LANCE carries no Iceberg metadata, so the worker skipped it only because the parse failed, and logged that as damaged metadata. The catalog records the format on the entry and this never read it. Reading it turns an accident into a decision, and separates a mixed catalog from a corrupt one in the logs. The property check beside it still covers the other shape: a real Iceberg table wearing table_type=lance, which is what the Lance namespace's Iceberg REST adapter writes. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * design: answer whether a Lance table needs maintenance It does, and index optimization has no Iceberg equivalent: rows written after an index was built are not covered by it, so a vector search quietly misses them. None of the three jobs can run in the Go worker, and there is no useful subset, because deciding what an old version still references means parsing Lance manifests. Version cleanup at least has an answer that needs nothing from us - Lance can enable it on the dataset itself. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * design: the Lance maintenance worker is a plugin worker, in Rust Framing it as a sidecar was wrong. plugin.proto already defines a language-agnostic gRPC contract for external maintenance workers, and "weed worker -admin=..." is the Go reference implementation of it from outside the admin process. seaweed-volume already compiles protos out of weed/pb with tonic_build, so a Lance worker is that build plus plugin.proto and the lance crate. Scheduling, retries, dedupe, progress and the admin settings page all come from the protocol: a worker that answers RequestConfigSchema with a descriptor gets its configuration form rendered without a line of Go. The data plane is the part that genuinely does need a process answering HTTP, and this had the two conflated. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * seaweed-worker: Rust plugin worker workspace, with Lance as the first one plugin.proto is language-agnostic and the Rust toolchain was already in the tree, so a Lance maintenance worker needs no new integration surface: core is the contract and nothing else, and a worker crate beside it supplies handlers and a binary. A second worker is a new member here rather than a fork of the protocol, which is why this is seaweed-worker and not seaweed-lance-worker. Verified against a running admin: it connects, is accepted, and admin prefetches descriptors for lance_compact, lance_optimize_indices and lance_cleanup_versions, so their settings pages render from the Rust side without a line of Go. The stream stays up across heartbeats. The job bodies are stubs that report failure. Doing the work means adding the lance crate and opening the dataset, and claiming success before that would be worse than saying so. Two things running it caught that reading the proto did not: the admin address has to be converted to the gRPC port the way pb.ServerToGrpcAddress does, or the dial fails as an h2 frame error; and the generated field names differ from the Go ones in several places, so JobCompleted carries success rather than a state enum. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance worker: implement compaction Detection lists tables from the namespace, opens each one, and proposes a job for any with more fragments than the policy allows; opening a dataset reads its manifest and not its data, so a sweep stays cheap. Execution re-resolves the table rather than trusting what detection saw - it may have been repointed, and the vended credentials expire - then compacts and reports the fragment counts either side. Verified against a live gateway: a twelve-fragment dataset became one fragment with all twelve rows intact. The test drives the handler directly and skips unless WEED_LANCE_NAMESPACE names a namespace, the way the Go integration tests skip without Docker. Running it turned up a gap the design had not: a gateway without STS vends no credentials at all, so the worker could not open anything and detection quietly proposed nothing. --access-key/--secret-key are the fallback, and whatever the namespace vends still wins over them. Two API assumptions did not survive contact either. Datasets open through DatasetBuilder::with_storage_options, not ReadParams, and lance 10's ObjectStoreParams has no storage_options field at all. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance worker: implement index optimization and version cleanup Index optimization is the job with no Iceberg equivalent: rows appended after an index was built are invisible to a search of it until this runs. Detection reads num_unindexed_rows from each index's statistics and proposes a table once more rows sit outside its indices than the budget allows; a table with no indices is skipped, which is different from one whose indices have fallen behind. Cleanup applies a retention window, refusing rather than silently dropping a tagged version, and leaving unverified files alone because they may belong to a commit still in flight. Both verified against a live gateway: 512 uncovered rows became 0, and a fourteen-version table lost its old ones. Each test now seeds what it needs, including building an IVF_PQ index and appending rows outside it. The first version of these depended on state a script had left, so the second run found the work already done and asserted nothing - a test that passes by doing nothing is worse than no test. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance: answer an empty catalog with an empty list, not null ListAllTables built its result from a nil slice, so a namespace holding no tables answered {"tables":null} on a field the spec marks required. A generated client may decode that differently from an empty list. Found running the namespace on a dev box, where the catalog was empty. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * admin: give Lance maintenance its own scheduler lane Lane assignment is a hardcoded map, so the three lance_* job types fell through to the default lane. That lane serialises its work under the cluster admin lock because volume management shares global state, which would queue a table's compaction behind volume balancing for no reason - Iceberg has its own lock-free lane for exactly this. Adds the lane, maps the three job types to it, and puts it in the sidebar beside Iceberg and Lifecycle. The lane routes were already generic, so only the nav was hand-written. The lane-coverage test spelled out the three known lanes, so a fourth failed it. It now checks against AllLanes(), which is the property it was reaching for and does not need editing next time. Found by connecting the Rust worker to a real admin: it registered fine and its job types were known, but they were filed under "default" and had no page. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance worker: log what detection saw "Detection proposed nothing" and "the worker could not read the table" look identical from the admin side, and the second is what a missing credential produces. One line per table separates them. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance worker: fix a leaked heartbeat and a silent reconnect loop spawn_heartbeat returned a handle to an empty task rather than the ticker it had just spawned, so aborting it aborted nothing and every reconnect left another heartbeat running against a dead channel. A stream that admin closes cleanly is not an error, but reconnecting in silence hides why. Two workers sharing an id evict each other forever and the log shows nothing but a login every five seconds - which is exactly how this presented on a dev box, and it took a look at the admin's own log to see it. The message now names the id to check. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance: a namespace cannot be created without its parent Storage keeps a namespace's parts flattened, so creating "a.b" with no "a" was accepted and left an intermediate that only existed inside a name. Listing derives child names by slicing those parts, so it reported "a", while describe and exists on "a" both answered 404 - a client walking the tree got a 404 on something the listing had just handed it. The spec asks for NamespaceNotFound when the parent is missing, which is also what keeps listing and describe telling the same story. Namespaces created through the S3 Tables API still bypass this, so listing keeps deriving intermediates rather than hiding whatever is already there. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * admin: say why a non-Iceberg table shows no schema The table pages read Iceberg metadata for schema and snapshots, and a Lance table has none, so both panels rendered "No schema available" - which reads as an empty table rather than a table this page cannot describe. The dataset behind the one that prompted this holds 1024 rows. The format is already on the entry and shown two rows above, so the empty states now use it: the catalog records where a LANCE table lives, not what is in it. Reading the schema for real needs Lance format code, which is the same wall as the data plane. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * seaweed-worker: run rustfmt over the workspace Committed the crates unformatted, so `cargo fmt --all --check` failed on files nothing had touched since. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * plugin: let a worker report what it saw about an object Admin cannot read a Lance table: it knows where the dataset lives and nothing else, so the details page had a location and two empty panels. The worker already opens every dataset during detection to decide whether it needs compacting, so it knows the schema, the row count and the fragment count at that moment. It just had no way to say so. Add a WorkerObservations body to the worker stream. Admin caches the last observation per object and serves it back, timestamped, for display; nothing schedules from it. The Lance compaction sweep reports what it opened, and the S3 Tables details page fills its schema panel from the cache when it has no metadata of its own, badged with when the worker looked and which worker it was. Nothing about this is Lance-specific past the reporting side, which is the point: any format admin cannot parse can describe itself the same way. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * design: record the observation channel Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * plugin: ask a worker for sample rows of a table admin cannot read Browse Data reads an Iceberg table's Parquet files directly, so it shows real rows. For a Lance table it showed "Table has no Iceberg metadata" and an empty grid, because there is no Go Lance reader and never will be one worth maintaining. The worker has the reader. Add RequestObjectPreview / ObjectPreviewResponse to the stream, mirroring the config-schema round trip that already exists, and give the Rust worker a PreviewProvider that scans the dataset and formats the rows with Arrow's own formatter, so a vector column reads as a vector. Admin picks the worker from the observation store: whichever one last described this table is the one that can read it. Unlike an observation the rows are not cached. They are the table's data rather than a description of it, and a copy sitting in admin would be both stale and nobody's business. The page fetches on load, bounded at 200 rows and a 15 second round trip, and drops the snapshot and data-file panels that only mean something for Iceberg. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * design: record the preview channel Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * test: disable the lance listener when two gateways share a host * test: keep AllocatePorts away from the lance default port * s3tables: let a table bucket declare the format it holds A bucket is a catalog, and a catalog serves one protocol. Format was recorded per table, so nothing could answer "where do I point a client at this bucket" without opening a table first, and an empty bucket had no answer at all. CreateTableBucket takes an optional format, stored with the rest of the bucket metadata and returned by Get and List. Empty means ICEBERG, which is what AWS S3 Tables serves and therefore what an SDK that has never heard of the field means. CreateTable refuses a table of another format, and CreateView refuses outright in a bucket that is not Iceberg, since a view is Iceberg metadata. Buckets that already exist carry no declaration and keep accepting anything, so nothing is migrated and nothing that worked stops working. The Lance namespace declares LANCE for the buckets it creates, which is what stops one of them being described to a client as an Iceberg catalog. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * admin: take the Lance port the way it takes the Iceberg one The UI cannot name the endpoint that serves a Lance bucket without it, and every format-aware page below needs to. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * admin: show which format a table bucket holds The bucket list printed an Iceberg endpoint for every bucket, including ones holding Lance datasets, where that endpoint serves nothing. It was the most visible place the UI assumed one format. The list gains a Format column and its endpoint column follows the bucket's declaration. The banner names both endpoints rather than asserting everything is Iceberg, and says so only for the servers that are actually running. Create Bucket picks a format with two cards rather than a dropdown, since what matters is not the name but which clients can read the result, and the endpoint under them updates as you choose so the operator leaves the modal knowing where to point one. A bucket from before the declaration existed shows "unset" in an outline badge, explained on hover. It is a fact about the bucket's age, not a fault, so nothing nags about it. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * admin: carry the bucket's format into the pages inside it Namespaces and tables are reached through a bucket, so both now say which catalog they belong to rather than making you go back up to find out. The tables list gains a Format column and a Rows column filled from what a worker last observed, since for a format admin cannot read that is the only row count there is; a table nothing has looked at shows a dash, not a zero. Create Table stops offering a choice the bucket has already made: in a declared bucket the format is fixed and says why, and only an undeclared one still offers both. Before this the select had exactly one option, hardcoded, which made a Lance table impossible to create from the UI at all. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * admin: let the table page speak the table's own format Partitions and Snapshot History are Iceberg's shape. Rendering them empty for a Lance table reads as a fault; a Lance table has neither, and says so by not showing them. In their place is a Versions panel, which is what that format calls its history, carrying the worker's timestamp so it is clear the numbers are a cached look rather than something read live. The breadcrumb carries the format badge, so the page names what it is looking at before you read a panel and wonder why it is empty. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * admin: show how to connect to either catalog, and group the two format workers The client examples on the buckets page were Iceberg's alone, so the one thing an operator wants after creating a Lance bucket - what to type to reach it - was not written down anywhere in the UI. Both formats now get a pair of snippets, and only for a server that is running. In the Workers menu, Iceberg moves below Lifecycle so it sits next to Lance: the two table-format workers together, the two cluster-wide ones above them. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * shell: create a table bucket of either format s3tables.bucket -create takes -format, so a Lance bucket can be made without going through the UI. The integration harness passes it too: its Lance tests were creating Iceberg buckets and getting away with it only because nothing checked. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * design: record that a bucket declares its format Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance: drop managed versioning; the store already orders commits The namespace offered itself as an external manifest store, so that a commit could reserve a version through a real put-if-not-exists. That was designed around a gateway that no longer exists: If-None-Match: * is reduced to a filer WriteCondition and evaluated at the object's owner under its per-path lock, or under the object write lock on the fallback path. Sixteen writers racing one fresh key get a single 200 and fifteen 412s, every time. Lance needs nothing else. commit_handler_from_url hands every s3:// dataset a ConditionalPutCommitHandler, which puts with PutMode::Create, which object_store sends as If-None-Match: *. So the feature solved a problem this store does not have, while moving a table's version history out of the dataset and into the catalog - and lance could not use it past the first commit anyway, since its own namespace-backed store answers "put_if_not_exists is not supported" to the second. The version operations answer Unsupported with the rest, managed_versioning is false, and the flag is gone. In place of the reserve-once test there is one that races eight writers at the manifest key through S3, which is the path a commit actually takes. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance worker: honour the version floor, the slot limits, and a shutdown Five findings from review, all of them things the worker claimed to do and did not. The version floor was checked when a cleanup job was proposed and ignored when it ran, so a table whose versions had aged past the retention window in between could be taken below the count the operator asked to keep. Execution now computes the floor itself and passes it as before_version; CleanupPolicy ANDs its clauses, so a version has to be both too old and below the floor to go. Both settings are clamped to the range the form offers, since Duration::hours panics on a large enough value and a negative min-versions wraps to a huge usize. Admin's shutdown was answered by returning from the stream, which the reconnect loop read as a healthy close and logged straight back in: the worker could not be stopped. serve_once now says which of the two happened. The advertised concurrency limits bounded nothing - every request spawned a task - and the heartbeat reported zero slots in use whatever was running. Both now go through semaphores sized from the limits, with the permits held for the life of the request and reported in the heartbeat. A namespace call had no timeout, so a gateway that accepted the connection and went quiet held a detection slot forever. And one table whose stats could not be read failed the whole sweep, losing the proposals for every table already scanned; it is now skipped and warned about, like a table that cannot be opened. The tests drove one shared catalog concurrently, which is why one of them asserted "no proposals at all" and passed by luck. They now take a lock and judge only their own tables. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * admin: fix the review findings on the format-aware pages The endpoint hint in Create Bucket built its HTML by concatenating the bucket name the operator is typing, so a name like <img onerror=...> ran in the admin origin as they typed it. It is built from DOM nodes now. A preview reply looked its channel up under the lock and then sent outside it, which Shutdown can close in between: a Gosched in that gap panics with "send on closed channel" every time. The send now happens under the lock. Observations were looked up by path alone, so a table dropped and remade in another format at the same path was described by the observation left behind. Lookups now have to agree on the format. Also: the Lance namespace caps a request body rather than reading whatever arrives; the details action no longer says "Iceberg" over a Lance table; mini stops advertising a catalog port when it is not running S3; a format whose server this cluster does not run cannot be picked in the modal or accepted by the API, since a bucket nothing can reach is not worth creating; and the unused catalogPortFor helper is gone. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance worker: let the control stream use mTLS The channel was hardcoded to http://, so off loopback the stream carried preview rows and execution commands in the clear - and a cluster with grpc TLS turned on would refuse the worker outright. --tls-ca, --tls-cert and --tls-key take the same certificates the Go worker reads from the [grpc.worker] section of security.toml, and must be given together: a CA on its own would quietly mean one-way TLS, which a mutual setup rejects anyway. Without them the stream stays plaintext, which is what the Go worker also does when nothing is configured. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance: answer null properties rather than an empty map The catalog does not keep a table's properties. Declare echoed the request's back and describe answered {}, both of which claim they were stored and are empty. Null says the catalog does not keep them, which is what the spec distinguishes and what is true here. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance worker: test the slot accounting The heartbeat reporting and the waiting are the two things the semaphores are for, and neither is observable from outside without catching a sweep mid-flight. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * test: fix the mixed-format catalog test, and name the binary it drives The integration suite passed locally and failed in CI on TestLanceRefusesIcebergTables. Both were right: CI builds the binary first, my tree had one from the day before, so locally the test drove a gateway with no format enforcement at all. The test itself no longer holds as written. It made a bucket, put an Iceberg table in it, and checked the Lance surface hid it - but a bucket that declares LANCE now refuses the Iceberg table outright. The invariant still matters from the other side, so it starts from an Iceberg bucket instead: Lance must not describe or list a table whose format it does not serve, and must refuse to declare one beside it. The harness now prints which weed binary it is about to run and when that was built. `make test` rebuilds first; a plain `go test` will happily drive a weeks-old binary and report a pass for code it never ran, which is exactly what happened here. Also make the row-limit conversion in the preview request explicitly bounded: CodeQL flagged the int-to-int32 conversion, and clamping by reassignment beforehand is not a form it recognises. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * lance: prove concurrent commits are kept, and preselect the only format on offer Two more from review. The commit test asserted that exactly one writer wins the conditional PUT, which is the mechanism, not the claim. The claim is that nothing is lost: the losers see the conflict, rebase and commit again. So there is now a test that has eight writers append to one dataset at once and counts the rows afterwards - all eight batches survive. That is also the sequence managed versioning could not finish, since its store refuses the second commit outright. And when Iceberg's endpoint is not running, the format picker offered two options with neither selected, so Create Bucket submitted no format at all, fell back to ICEBERG, and was refused by the guard added last round. Lance is preselected when it is the only format this cluster serves. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * Clamp the remaining worker settings, and bootstrap buckets in a served format Compaction and index optimization read their thresholds and cast straight to usize and u64, so a negative arrives as an enormous number and turns the threshold into "never": compaction and reindexing both go quiet with nothing to say. The cleanup job was fixed last round; these are the same bug. Clamped to the values that stay meaningful rather than to what the form offers - zero uncovered rows is a real setting, meaning reindex as soon as anything is not covered, so the floor there is zero and not the form's thousand. mini pre-creates the buckets named by -tableBucket, and did so without a format, which now means Iceberg. Started with the Iceberg endpoint off and the Lance one on, that left buckets nothing could reach and which refused every Lance table. It takes the format from the endpoint that is actually running, and creates nothing when neither is. Claude-Session: https://claude.ai/code/session_01Rkp1Mw5E89Jp6dzJFYiMrm * s3: allow-unordered is a listing parameter, not an unimplemented subresource The guard that stops a bucket GET with an unknown subresource from being answered with a listing does not know about allow-unordered, so it answers 501 NotImplemented - to a parameter the listing handlers already read and already validate against delimiter. This is why test_bucket_list_unordered and test_bucket_listv2_unordered fail in the Ceph s3-tests suite. They fail on master too; this is not a Lance change and can be taken on its own.

Fix what the Go 1.26 language bump breaks (#10794)
* worker: log the balance move stage through a constant format string Go 1.26's printf analyzer now follows printf wrappers reached through an interface, so passing the stage straight to Logger.Info is a vet failure. * s3api: bracket the IPv6 host in the signature test URL A bare IPv6 literal is legal in a Host header but never in a URL. Go 1.26 stopped parsing it leniently, so carry the two forms separately and set r.Host to the value the client would actually have signed. * mini: bracket IPv6 addresses in the readiness probe URLs An IPv6-only host hands mini a bare literal, and %s:%d pasted it into a URL unbracketed. Under Go 1.26 that URL no longer parses, so waiting for the admin server never succeeds and mini refuses to start. |

iceberg: vend table-scoped credentials to clients that ask for delegation (#10777)
* iceberg: vend table-scoped credentials to clients that ask for delegation The catalog recognised X-Iceberg-Access-Delegation: vended-credentials and then deliberately said nothing, because it had nothing to vend: it withheld even the S3 endpoint so the client would keep the credentials it was configured with. That left every engine expecting the catalog to hand out access - Snowflake, Databricks, Trino with vending, any multi-tenant setup - needing static S3 keys distributed out of band. Mint an STS session per request instead, scoped by a session policy to the table's own prefix plus the bucket listing needed to resolve it, and return it in the load response config and storage-credentials. The role to assume is named by -s3.iceberg.credentialRole; its trust policy is what decides whether a caller may assume it, and vending stays off until it is set. A failed mint falls back to the old silence rather than handing back an endpoint the client cannot sign for. * iceberg: keep vended credentials inside the table prefix Review follow-ups on credential vending: Listing was granted on the bucket ARN with no condition, so a credential vended for one table could enumerate every other table's object names. Constrain s3:prefix to the table's own prefix, which the S3 gateway already populates for list requests. A table location carrying * or ? would have gone into the policy's resource pattern unescaped and widened the session to sibling prefixes. Refuse to vend for such a location rather than escaping it; nothing the catalog generates contains those characters. DurationSeconds skipped the 900..43200 bounds the other assume-role paths enforce, so -s3.iceberg.credentialDurationSeconds could ask for a session outside them. The check is now shared by all three entry points. * iceberg: return the vended credentials from buildFileIOConfig itself buildStorageConfig was a second name for what buildFileIOConfig already did; it now returns the storage credentials alongside the properties, and callers that only want the properties drop them. * iceberg: split the vended bucket grants, and refuse a whole-bucket scope The prefix condition sat on a statement that also granted GetBucketLocation and ListBucketMultipartUploads, neither of which carries an s3:prefix to satisfy it, so both were denied for every vended credential. GetBucketLocation moves to its own unconditioned statement. ListBucketMultipartUploads is dropped: Iceberg writers complete and abort by upload id, and granting it either leaks in-flight keys bucket-wide or breaks on the same missing prefix. A table whose location has no prefix - one registered at the bucket root - would have been vended read and write over every other table in the bucket. Refuse, the way a location with wildcards is refused. |

mount: invalidate hot directory listings by section (#10712)
* mount: invalidate hot directory listings by section A cached directory used to be dropped whole when it saw 64 changes in 2s: with a continuous writer the listing cycled through wipe, direct listing and full rebuild for as long as the writer kept going, and every sibling lookup fell through to the filer in between. Split each cached listing into name-range sections of 1024 entries. A burst of foreign changes invalidates just the section it lands in; entries stay served and events keep applying, and the next readdir re-lists only that range from the filer, reconciled through the version gate so it cannot roll back newer applied events. Lookups in an invalidated section read through until then. The mount's own writes no longer invalidate anything: they are ground truth for its cache. * meta_cache: drop the version floor with a deleted or moved directory The other teardown paths already clear both maps; a floor left behind here would fence the listing of a directory re-created at the same path. * mount: harden section refresh An unversioned listing (pre-upgrade filer) now only fills gaps instead of reconciling: without a snapshot to order against, an overwrite or the deletion sweep could roll back an event applied after the listing. The section table can be rebuilt or re-split between the listing and its apply, so the refresh only marks fresh or splits when the section still covers the range it read. Splicing bounds from a stale range into a rebuilt table could leave them unsorted. Bound the wait: a readdir gives a refresh five seconds before serving the maintained-but-unverified cache. Bound the size: a range grown past four sections aborts the refresh and drops the directory cache, re-tiling it with a full rebuild, with that request served direct. Cover the filer-facing path with a listing server: paging with the snapshot pinned across pages, the section cutoff, no calls for a fresh section, and the overgrown-range abort. * meta_cache: make the section table a self-contained state machine Churn counting, freshness, stale-range scanning and the refresh completion with its guard and split now live on dirSections itself, free of the lock, the store and the apply loop, so they test directly with synthetic clocks and tables. MetaCache keeps thin wrappers that hold its mutex and find the directory's table. * meta_cache: keep section internals out of the apply request The request now carries the completed build's table and one refresh as opaque values built by section code, and the boundary-derivation rule moves out of the build loop into a collector next to the rest of the section logic. * mount: fence refreshed sections with a snapshot floor A refresh versioned the entries it fetched and tombstoned the ones it swept, but a name absent from both cache and listing kept the old directory floor, so a delayed event between the two snapshots could resurrect it into a section already marked fresh. The section now carries its own floor, consulted next to the directory floor, covering every name in the range, present or absent — which also retires the refresh's per-entry version stamps and sweep tombstones. An unversioned listing sets no floor and vouches for nothing: it may still fill gaps, but the section stays stale and reads through until a filer that stamps snapshots re-validates it. A listing's reach is unknowable up front — a resumed handle can skip far ahead, and shrunken sections let one batch span many — so a readdir now re-validates every stale section from its start name to the end of the directory instead of the next two. * mount: fence tombstoned names with floors and gate the reconcile A tombstone answered for its name before the floors were consulted, so one at an old position let through events the newer listing floor should have fenced; a build never hit this because it prunes superseded tombstones, which a section refresh does not. The version gate now raises a tombstone to the floors like any other record. With no per-entry versions, only the section floor fences a reconcile's work, so a range the rebuilt or re-split table no longer has must not touch the store either: the range check moves ahead of the mutations, under the same lock the floor install holds. An unversioned refresh no longer retries: the section is remembered as unverifiable and skipped by the stale scan, or every batch of every readdir would re-list the same ranges against a filer that cannot vouch for them. * mount: clear beaten unversioned markers and skip refresh mid-build An unversioned marker outliving the snapshot write that replaced its content bypassed the section floor the same way an old tombstone did, letting a delayed pre-snapshot event roll the entry back. The refresh now clears the marker when its write wins; pinned local-only entries are not replaced at all, keeping their content and marker. A rebuild wipes and repopulates the store off the apply loop, so a refresh reconciling meanwhile could sweep children the build had already inserted and let it publish the directory incomplete. The refresh now skips a building directory, as events (buffered) and purges (skipped) already do; its staleness dies with the build's fresh table. * mount: clear the unversioned marker only after its replacement lands Clearing before the insert meant a failed write left the old local content claiming the listing floors, fencing the very events that were still entitled to correct it. * meta_cache: rename the section state machine to sectionList dirSections named both the type and the map of them. * mount: raise the default cacheDirMaxEntries to 100000 The low ceiling guarded against whole-listing rebuild churn: a big cached directory under writes kept re-streaming everything. Sectioned invalidation ended that — a burst now costs one range listing — so the remaining cost of caching a large directory is its one-time build, comparable to the single direct listing that read-through mode pays on every enumeration instead. * meta_cache: cover section border and edge cases A bound-named entry belongs to the section starting at the bound: the neighboring refresh's sweep stops before it, its own section's covers it. Churn past everything the build saw lands in the tail section, a rename spanning two sections invalidates both, and a listed entry at the section's end name is cut off with the ones beyond it. |

windows mount: cache file data, resolved paths and attributes (#10703)
* benchmark tool for mounted filesystems * ci: on-demand mount benchmark, native WinFsp vs rclone plus a Linux reference * windows mount: let the Windows cache manager cache file data WinFsp only turns the cache manager on for a file when FileInfoTimeout is infinite; at any finite value every application read and write is a synchronous trip into the mount process at whatever size the application issued. Metadata events already reach FspFileSystemNotify, which purges a changed file's cached pages and attributes, so an infinite timeout stays coherent. The dir listing, volume info and EA timeouts are pinned to one second so they do not silently inherit the infinity. * windows mount: cache resolved paths and attributes in the adapter WinFsp addresses every operation by path and has no FORGET, so the adapter walked the whole path through Lookup on each one, and in a directory the filer has not listed yet every walk was a filer round trip; nothing played the part of the kernel's dentry and attribute caches. The path cache owns one lookup reference per entry the way the kernel holds one until FORGET, serves attribute reads for files without an open handle, and is purged by the mount's own mutations and by metadata events, with the timeout as backstop. * windows mount: keep a closed file's attributes cached Open steals the path's cache entry for its handle and Release returned the reference with a purge, so the stat that follows every copied file walked to the filer again. Reading the handle's final attributes before it goes away and moving the reference back into the cache serves that stat locally, the way the kernel's attribute cache does after a close. Only if the path still names that inode, though: WinFsp reports the path the handle opened with, and after a delete-on-close or a rename caching it would resurrect an entry that is gone. * windows mount: persist entries at create, and let the flush stay at close WinFsp posts the cleanup and close that carry the flush after CloseHandle has returned, so deferring the filer entry to the flush let everything that reads through the filer race an unflushed close: a listing missed just-written files, and a directory rename moved a directory on the filer before its newest child existed there, leaving the straggler flush to recreate the child under the dead path. Flush-at-cleanup is not the answer either: it makes every handle's cleanup flush, and those flushes race the unlinks of delete-on-close, re-inserting the entry the unlink just removed. Persisting the entry at create takes the ordering question away. * mount: flush written pages before a truncate shrinks past them The shrink trims chunks, but written pages that have not become chunks yet are invisible to it, so the next flush wrote them back and the file grew again, resurrecting the truncated bytes. Windows hits this on every write-then-shrink because its flush runs after CloseHandle, but the gap is platform-neutral. * mount: order a file's unlink against its in-flight flush Unlink set the handle's deleted flag bare, so a flush already past its own check of that flag wrote the entry back right after the delete removed it, and a delete-on-close file outlived its last handle. The flag is now set under the handle's flush lock and re-checked under it, so a flush either completes before the delete or sees the flag and skips. An eagerly created handle also starts clean: the dirty mark existed to make the deferred filer create happen at flush, and eager creates have nothing to flush. |

filer: add filer.meta.scan to audit one directory's change history (#10645)
* filer: drain pending log chunk refs when the metadata stream ends In metadata chunks mode the server sends log file refs in responses of their own, and the client can only read them once it knows the run of refs is over. That was inferred solely from the arrival of a normal event, so refs still pending when the stream ended were dropped: the subscription returned no events and no error. A follower never noticed, because it runs forever and a live event always arrives to close the run. A bounded subscription — StopTsNs set, range already in the past — can receive nothing but refs and then EOF, and silently reports that nothing happened. For anything auditing a path that is the worst possible answer, since an empty result is indistinguishable from a quiet period. Drain on EOF as well as at the transition point. * filer: add filer.meta.scan to audit one directory's change history Reconstructing what happened to a path means replaying the metadata log, and filer.meta.tail is built for watching rather than auditing: it follows forever unless given a stop, prints multi-line JSON, and takes ranges only as durations before now, so an incident timestamp has to be converted by hand. Its -pattern also cannot find a versioned object. A versioned key is stored as <key>.versions/v_<id>, so the events carry the names "<key>.versions" and "v_<id>" and a pattern of the object's own name matches neither — the search comes back empty while the object is being written continuously. filer.meta.scan prints one line per change, stops at the end of the range, accepts absolute -since/-until with an explicit -tz, and reports versioned writes against the object key with the version id alongside, so -name matches the key a client would ask for. Delete markers are labelled as such rather than appearing as zero-length writes, and pointer flips on the .versions container are distinguished from writes of object data. * filer.meta.scan: read persisted log chunks from the volume servers Reading a range through the filer makes it decode every log entry in that range and filter each one, so the cost lands on the filer and does not shrink when the prefix is narrow — only the bytes on the wire do. On a cluster whose metadata log is dense that is the expensive part of a scan, and it is charged to the process least able to spare it. Enable metadata chunks mode: the filer hands out log chunk ids and the scan reads them from the volume servers itself. ReadLogFileRefs re-applies the same path filter client-side, so the output is unchanged — verified identical to the filer-read path over the same range, including after a restart drops the in-memory buffer and the data must come off disk. Direct read needs a route to the volume servers that the filer does not, so a failure before anything has been printed retries through the filer; retrying after partial output would duplicate lines. -directRead=false forces it. * filer.meta.scan: confirm an empty direct-read result through the filer An audit that returns nothing is read as "nothing happened here", so it is the one answer that must not be produced by a bug. Direct read has more ways to come back empty than the filer path does — it needs a route to the volume servers, and it depends on the ref-drain contract holding. When direct read yields no changes, re-run through the filer before reporting it, and warn if the two disagree. Re-running is safe only because nothing was printed; after partial output a replay would duplicate lines instead, so that case reports the error rather than retrying. |

mount: read oversized directories through instead of caching them (#10631)
* mount: read oversized directories through instead of caching them Visiting a directory pulls every child from the filer into the local LevelDB before the first listing returns. For a directory of a few million entries that is minutes of streaming, gigabytes of local store, and gigabytes of decoded entries in flight -- paid by a mount that may only walk the directory once. A build that crosses -cacheDirMaxEntries (default ten thousand) now stops, cleans up, and marks the directory read-through: listings stream from the filer with pagination, the way update-hot directories already do, and lookups in it consult the filer per entry as any uncached directory does. The refusal is remembered, so the next visit fails fast instead of streaming to the limit again, and an oversized ancestor is stepped over when caching its subdirectories rather than wedging every listing beneath it. The direct path keeps the same pagination state on the handle, so a walk that crosses the limit mid-flight carries on from where the cached walk reached. * mount: an ancestor found oversized must not fail its descendants Visiting a directory builds its whole uncached ancestor chain in one group, so the first discovery that an ancestor is oversized cancelled the group and surfaced as the listed directory's own refusal: the descendant build was aborted and the caller marked the descendant read-through, leaving a perfectly cacheable directory streaming from the filer until its inode was forgotten. The earlier test missed this by pre-marking the ancestor, which exercises only the fast path. The refusal of any directory other than the one being listed is now kept out of the group's result; it is already remembered for the next visit. |

mount: tell windows about changes made elsewhere (#10553)
* mount: tell windows about changes made elsewhere Nothing invalidates a Windows client's cache from this side, so a file created or removed by another mount, the S3 gateway or the filer API stayed invisible in Explorer until the user refreshed by hand. The mount already receives those events; they just had nowhere to go. WFS gains a listener for every applied metadata event, and on Windows that turns into the WinFsp notification for the path. A rename reports both ends, since the destination's own event may never arrive when it falls outside this mount. * mount: report a removed directory as a directory Entry is nil once a path is vacated, so asking it whether the thing that went away was a directory always answered no and every removal was reported as a file. Windows watches the two through different filters, so a folder removed elsewhere never refreshed. The invalidation now carries what used to be there, which the event already knew and simply was not passing on. * mount: report a rename destination once The event stream already carries a second invalidation describing the new path, so reporting RenamedTo here sent the destination twice — and always as a create, so a moved directory arrived as a create followed by a mkdir. |

mount: support mounting on Windows through WinFsp (#10536)
* mount: add the WinFsp filesystem adapter WinFsp speaks a path-based FUSE dialect; weed/mount implements the inode-based raw protocol the Linux kernel uses. This translates between them so Windows runs the same filesystem code as everywhere else rather than a second implementation: paths resolve to inodes one Lookup at a time, and the raw operations run unchanged underneath. Errno translation is spelled out rather than passed through. Go numbers Windows errnos as offsets from APPLICATION_ERROR, so the raw value would mean something unrelated by the time WinFsp read it. Hard links return ENOSYS since WinFsp has none, and byte-range locks stay with its kernel driver rather than the mount's lock table. Not reachable from the mount command yet. * mount: build the winfsp errno table with explicit precedence Platforms alias errnos differently: freebsd has no ENODATA and linux makes ENOATTR the same value as it. A map literal with colliding constant keys does not compile, so build the table and let the first entry win, keeping the general codes their own meaning. * mount: wire the winfsp adapter into the mount command RunMount was one function doing filer setup, mount-point preparation and serving. The setup is the same everywhere, so it moves to mount_common.go and each platform keeps only what differs. Windows differs mostly in the mount point: WinFsp wants a drive letter or a path that does not exist yet, so none of the unix preparation applies, and a bad one is worth rejecting up front because WinFsp reports failure as a bare false. Adds -windows.caseInsensitive for software that expects Windows naming rules. * ci: mount on windows and exercise it Builds weed.exe, installs WinFsp, starts a cluster, mounts S: and runs a test suite against it: round trips at several sizes, offset writes, rename, delete, nested directories, concurrent writers, and a directory wide enough to stand in for the case that prompted this. Nothing else here can run the Windows mount, so without this the adapter is only known to compile. * ci: build the windows mount without cgo The runner has MinGW, so cgo is on by default and cgofuse compiles its cgo variant, which needs WinFsp's headers. The nocgo variant loads the DLL at run time and is what the released weed.exe uses. * mount: make the winfsp path splitting portable and test it resolve and resolveParent had the splitting inline in a windows-tagged file, so the cases that matter most there — both separators, empty and dot components, the root having no parent to create in — could not be tested on any runner that builds this. * test: check the windows mount persists across a remount Reading a file back through the same live mount proves nothing about durability; the answer can come from the mount's own caches. Write the fixtures, confirm the filer serves them with the mount out of the path, then re-read after a teardown and remount. * test: cover the windows mount operations that had none Truncate, append, chtimes and the hard-link refusal were implemented but never exercised, and the errno table was only unit-tested for mapping, never end to end. Adds names that have to survive the UTF-16 boundary, rename over an existing target and across directories, and concurrent handles on one file rather than one file each. * ci: dial the filer over ipv4 and run the persistence phases localhost resolves to ::1 first on windows and the cluster binds ipv4 only, so the mount's grpc dial was refused while the http readiness probe passed by falling back to ipv4. * ci: pin the cluster to loopback and probe ports by connecting weed mini advertises the runner's LAN address and binds filer grpc there, so the mount's dial to 127.0.0.1:18888 was refused while http answered. The readiness probe also passed with nothing on 18888: Test-NetConnection reported success for a port that then refused a connection, so it now opens a socket instead. * ci: report listening ports before mounting The readiness probe connects to the filer grpc port and the mount is then refused on it, which cannot both be true; print the actual state. * ci: run the cluster, mount and tests in one step The runner tears down a step's process tree when its shell exits, so the cluster started in an earlier step was already gone: the readiness probe passed against a live filer, the step ended, and the mount then found nothing listening. A diagnostic step reported no weed.exe at all. Everything that needs those processes alive now shares a step. * mount: key windows file io on the handle, not the path Read and Write walked the path on every call to fill in a NodeId the raw filesystem never reads: both look the file up by handle. Under eight writers creating files in one directory the walk transiently missed and the write failed with ENOENT before reaching the filesystem at all. Same for flush, fsync and the release calls. O_EXCL now fails on an existing name instead of taking it over, and Symlink is refused: the entry is easy to create but WinFsp only follows it once the reparse point is wired up, so it read back as an empty file. * mount: translate cgofuse open flags for windows cgofuse reports MSVC's numbering and the raw filesystem tests Go's, so only the access mode and O_TRUNC lined up: O_EXCL arrived as O_APPEND and O_CREAT as nothing at all. Also report which handle a failed write was using, to tell a handle that was never issued from one released while still in use. * mount: report which step of a windows create failed A concurrent create fails with ENOENT and the path walk, the parent lookup and the create itself are indistinguishable from the caller. * ci: send weed logs to stderr on windows glog writes to its own files by default, so the mount's own error output never reached the redirected log. Its flags are global and have to come before the subcommand. * mount: resolve known paths from the inode table on windows Every create walked the parent chain with a filer lookup per component. With eight writers creating files in one directory that is hundreds of concurrent lookups of the same parent, and lookupEntry reports an authoritative ENOENT when the directory is cached, the entry is not in the cache and the inode table has no record — a window a concurrent refresh can open for a directory that plainly exists. A path the mount already tracks now resolves straight out of that table. * test: sync the windows persistence fixtures before closing The mount is killed rather than unmounted, so anything still queued for flush is legitimately lost and the test was measuring crash durability while calling it persistence. A 9MB file lost four chunks that way. * mount: keep the lookup refresh on the target path Resolving a tracked path straight from the inode table skipped Lookup, which is also what refreshes the entry: a truncate then read back the pre-truncate size. Only the parent chain takes the shortcut now, which is where the concurrent creates were racing anyway. * mount: log every windows resolve failure Open suppressed ENOENT and Getattr logged nothing, which hid the two callbacks that can report a missing file during a create. * mount: drop dot entries from windows directory listings readdir reports "." and ".." for the kernel, but Windows enumerates a directory without them and displays whatever it is handed, so a folder of 200 files listed 202. Go's ReadDir filters them, which is why only the PowerShell walk caught it. * mount: flush queued writes when windows mount is interrupted The signal handler exits the process the moment its hooks return, so the WaitForAsyncFlush after Serve never ran on ctrl-c and queued writes were dropped. * mount: let windows mount over an empty directory WinFsp turns a directory mount point into a reparse point, which NTFS allows on an empty directory and refuses on a populated one. The check rejected every existing directory, so the ordinary habit of creating the mount point first failed with a message saying it should not exist. CI now mounts over a pre-created directory and writes through it. * ci: run the windows mount check on any pull request It is the only thing that exercises the Windows mount, so restricting it to pull requests based on master skipped it for stacked ones. Replaces the branch name that was pushed to trigger it. * mount: do not log a missing windows entry as an error Windows probes for entries that do not exist as a matter of course, so ENOENT from getattr and open is an answer rather than a fault and would have filled the log. * mount: take the fast path for parent chains in every windows resolve Narrowing it to resolveParent left Getattr and Open re-walking the parent with a filer lookup per component, and those are what Windows calls before a create: eight writers in one directory still raced a meta cache refresh there. Only the final component needs the Lookup refresh. The pass that suggested otherwise came from a run five times slower than the failing ones, where the race had no room to appear. * mount: drop the windows path resolution shortcut Resolving from the inode table skipped the Lookup that refreshes an entry, and a truncate then read back its old size. Applying it only to the parent chain kept truncate correct but left concurrent creates failing, and applying it to the final component too inverted that. The two cannot both be satisfied this way, so this returns to looking up every component and leaves the concurrent create failure open. * mount: fall back to the open handle when a deferred entry is evicted A create that defers the filer write leaves the entry only in the local cache. Creating many files at once pushes the directory past the hot threshold and evicts it, taking that placeholder with it, so a lookup went to the filer, found nothing, and reported a file that plainly exists as missing. The handle still holding the unflushed entry is authoritative for it. Caught by concurrent creates over a Windows mount, which resolves a path on every call rather than relying on a kernel dentry cache. * mount: let cgofuse resolve to the version the module graph requires rclone already depends on cgofuse at a newer commit than the v1.6.0 pin, so readonly builds refused the go.mod until it matched what MVS picks. The interface and flag values the adapter uses are unchanged there. * mount: wait for a pending async flush before looking up on the filer Open, unlink and rename already wait, but a plain lookup went straight to the filer and read pre-close metadata: truncate a file, close it, and a path probe during the flush window reported the old size. The kernel attr cache hides this on linux; a front end that resolves paths on every operation hit it directly. * mount: reject a umask wider than the file mode it becomes ParseUint allowed 64 bits and the result is narrowed to os.FileMode, which is 32, so an out-of-range umask truncated silently instead of being reported as unparseable. * mount: address review findings on the windows mount WaitForAsyncFlush closed its channel unconditionally and shutdown reaches it from both the interrupt hook and the path that resumes after serving, so a ctrl-c could panic on a second close. The deferred-entry fallback read an open handle's entry without its lock, which is what the other two readers of that field take so FromPbEntry does not walk the chunk slice mid-append. The async-flush wait also sat ahead of the meta cache, making every stat of a recently closed file queue behind uploads; it belongs just before the filer is consulted. Windows entries were persisted as uid 0: the raw filesystem stores InHeader's owner and the adapter left it zero. They now carry the identity the mount was started with. The errno table used Linux numbering while cgofuse decodes MSVC's, so ENAMETOOLONG arrived as EDEADLK and five others were likewise wrong; a windows test pins each value to cgofuse's own constant. Also: break the filer handshake loop on success rather than always running ten rounds, accept a drive letter written S:\\, report a missing WinFsp instead of panicking, keep commas out of the volume label, and drop -windows.caseInsensitive, which told WinFsp the mount folds case while lookups stayed exact. * mount: return windows lookup references so the inode table stays bounded Every operation that hands back an EntryOut grants a reference the Linux kernel returns with FORGET. WinFsp has no FORGET, so the adapter took one per path component per call, plus one per child of every readdirplus, and never gave any back: inodeToPath grew for the life of the mount. Walking the 200k-file directory this exists for stranded 200k references. The adapter now plays the part the kernel plays. Each resolution releases what it took, and an open handle keeps the reference for its inode until Release, counted because the raw filesystem reuses one handle for repeated opens. Holding it is not optional: completeAsyncFlush skips the metadata flush when the saved path no longer maps to the inode, so releasing early would lose a close's metadata. Also stops persisting the display owner. -o uid=-1 makes WinFsp report the calling user whatever we say, but the value handed to the raw filesystem is written to the filer, and 4294967295 is what every other client would read. -windows.uid and -windows.gid set what is recorded. * mount: fix windows behaviours the reference implementations guard against WinFsp has no ro option — it discards the flag and leaves the volume writable — so -readOnly accepted writes and deletes. The refusal now happens in the operations themselves. Windows sends times around its own 1601 epoch, which arrive as a large negative second count; casting them through stored a year-1601 timestamp that every other client then read. Those are now left alone. rclone carries the same guard. Chown returned ENOSYS, and WinFsp passes a chown failure straight out of SetSecurity, so Explorer's Security tab and icacls failed for edits that were not about ownership. It now accepts and discards. Only create and mkdir presented a caller; the rest sent uid 0, which hasAccess treats as root, so deletes and renames skipped the permission check that creates got. Every operation presents the same identity now. A drive letter written S:\ reached WinFsp unnormalised, which recognises a drive only as exactly two characters and then failed as a directory path. A test also pins the open flag translation, since swapping O_EXCL and O_TRUNC would turn 'fail if it exists' into 'truncate it'. * mount: answer windows getattr and truncate from the open handle WinFsp keeps the path a handle was opened with and never updates it when the file is renamed, so resolving the path again fails on a handle that is still perfectly valid — the ordinary write-temp-then-rename save pattern. The handle already knows its inode, which also removes a full path walk from two operations WinFsp calls constantly. Readlink on the root now refuses. WinFsp probes there to decide whether the volume has symlinks and enables them unless it fails, and with them on it resolves a path a component at a time, each one reaching us as its own walk — all for a feature Symlink already refuses. * mount: require the windows mount directory not to exist WinFsp creates the directory itself with FILE_CREATE and removes it when the filesystem goes away, so an existing one — empty or not — fails with "mount point in use". Allowing an empty directory was wrong, and the CI check that appeared to prove otherwise was the vacuous one: listing a plain directory succeeds whether or not anything is mounted on it, so the step passed while the mount had failed and the writes went to local disk. That check now waits for the reparse point, which is what caught this. * mount: apply review comments on the windows mount -windows.uid and -windows.gid reached the adapter but not the filesystem parameters, which is what carries the owner written to the filer, so the flags changed nothing. Readdir re-resolved the path while Getattr and Truncate answer from the handle; a directory renamed during an enumeration then failed on the stale path WinFsp still holds. Utimens now honours UTIME_OMIT instead of writing whatever came with it. * mount: tag the unix-only lock tests away from windows The production lock files were tagged when the package was made to build on windows, but the tests that exercise them were not, so anything that compiles tests for windows still failed on syscall.F_WRLCK. * ci: vet the mount tests for each target too Only compiling the non-test build let an untagged test keep a per-OS syscall constant without anything noticing. |

telemetry: report anonymous cluster stats by default (#10488)
The reports are what tell us which versions and cluster sizes are actually in use, and almost nobody flips the flag on, so the numbers we have are close to useless. Default it on for master, server and mini, and say in the flag help and the startup log how to turn it off. Nothing new is collected: still an in-memory cluster id that changes on restart, version, os, server counts, volume count and disk bytes, sent once a day by the leader master only. |

ci: fix FUSE mounts against the new runner image (#10484)
* ci: restore the setuid bit on a shadowed fusermount3 Newer ubuntu-22.04 runner images carry a source-built fusermount3 in /usr/local/bin that shadows the distro one in PATH and is not setuid root. go-fuse looks the helper up through PATH, so every unprivileged mount fails with "mount failed: Operation not permitted". * test: fail a fuse test as soon as its mount process dies A mount that cannot mount at all exits within a second, but the harness still waited out the 30s readiness timeout and then reported "mount point not ready within timeout", leaving the real cause buried in the log tail. Watch the child processes and report their exit instead. * mount: report a failed mount without a goroutine dump A mount failure is an environment problem - no /dev/fuse, fusermount not setuid, stale mount point - and the all-goroutine stack dump Fatalf adds buries the one line that says so. |

s3: register the advertised ip with the master (#10482)
* s3: register the advertised ip with the master The cluster address came from the bind ip, falling back to the auto-detected interface, so -ip never reached the S3 registration. weed mini -ip=localhost binds the wildcard and ended up registering whatever interface happened to sort first -- on a host with VPN interfaces, an address that stops routing once the tunnel drops. IAM changes are pushed to registered S3 servers over gRPC, so every mutation then blocked the full 10s propagation deadline before logging a failure, and cluster.ps and the admin UI listed a node nothing could reach. Identities still arrived through the /etc/iam metadata subscription, so this cost latency and visibility, not credentials. Add an advertise ip to the gateway option, preferring it over the bind address, and wire the parent -ip through server, filer and mini. * s3: treat any unspecified bind address as a wildcard net.ParseIP + IsUnspecified covers ::, [::] and the expanded IPv6 forms instead of only the 0.0.0.0 literal, so an IPv6 wildcard bind no longer registers an address peers cannot dial. Host names parse as nil and stay addresses in their own right. Apply the same guard to the advertised ip. |

azure: let the blob endpoint be configured (#10460)
* azure: let the blob endpoint be configured The service url was always derived as <account>.blob.core.windows.net, which leaves out Azure Government, Azure China, and private endpoints. Name the blob service url instead and those accounts become reachable. The url has to be https, since the account key or the bearer token would otherwise travel in the clear. * azure: reject an endpoint that carries no hostname A url like https://:443/ has a host of ":443", so the emptiness check on Host let it through and the request only failed once it reached Azure. The hostname is what has to be there. |

mount: report data sizes to df with -df.logical (#10459)
df on a mount shows the space the cluster gives up to the data: every replica of a regular volume, every shard of an ec one. That is the honest answer for capacity planning, but it is not the question a user asks when they want to know how much of their data is stored. Add -df.logical. The master reports the logical sizes alongside the raw ones: one replica per regular volume, the data shards of each ec volume counted once. Free space is divided by the copies the requested replication makes, so used plus available stays the amount of data the mount can still write, and it comes off the cluster-wide usage rather than one collection's, since capacity is cluster-wide too. Statistics through a filer resolves an unset replication to the filer's default rather than the master's, matching where the writes it is sizing for actually land. The flag governs the quota check too, so a mount has one notion of how much it is using. A filer that predates the new fields sends zeros, and the mount keeps reporting the raw sizes. |

azure: authenticate with Entra ID instead of a storage account key (#10456)
* azure: authenticate the blob sink with Entra ID Shared account keys have to be distributed and rotated everywhere a sink runs. Leaving account_key empty now falls back to the identity chain, so a workload identity or managed identity carries the authorization instead. * azure: authenticate remote storage with Entra ID The remote storage client demanded an account key and refused to start without one. Fall back to the identity chain when it is absent, and let azure.client_id pin a user-assigned identity. * azure: reject a malformed storage account name The account name is interpolated into the service URL, so a name carrying a "/", "?" or "@" moves the authority elsewhere and an authenticated request follows it. Hold callers to Azure's own naming rule instead. * azure: keep a leftover environment key off the identity path A configured client id asks for Entra ID, but AZURE_STORAGE_ACCESS_KEY still filled in the account key behind it. An old mounted secret would go on authenticating until it rotated, and the failure then blamed the key. * azure: say what the identity path reads from the environment A pinned client id alone is not enough for workload identity: the tenant and the projected token come from the environment, and missing them only surfaces later, when a token is first requested. |

filer: make the redis connection settings configurable (#10441)
The sentinel stores hardcoded a 30s read timeout and a 1m retry backoff. After a sentinel failover every request that picked a pooled connection to the old master sat there for 30s before the connection was retired, and the pool timeout derived from it (read timeout + 1s) queued the rest behind them. The other redis stores took the go-redis defaults with no way to tune anything. Read the dial, timeout and pool knobs from each redis store section instead, keeping the go-redis default for every key left unset. |
