Chris LuandGitHub	8c7d714d5e	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.

Chris LuandGitHub	9a7cfaf371	admin: stop holding the shell admin lock across whole scheduler batches (#10290) ... * admin: let waiting shell clients win the admin lock The admin lock manager re-acquired the cluster shell lock immediately after releasing it, while a waiting weed shell client only polls the master once a second, so an operator could lose the race indefinitely. Leave the lock free for slightly more than one poll interval before re-acquiring, and once overlapping reference-counted holds have kept the lock continuously held for over a minute, make new admin-side acquires wait for a full release before piggybacking. * admin/plugin: take the shell lock per detection and per job, not per batch The default-lane scheduler acquired the cluster shell lock once and held it across the whole pass: every due job type's detection plus all of its dispatched jobs, each drained to completion. A manual weed shell operation sharing that lock could stall behind the batch for up to the extended execution window. Hold the lock only while it protects something: around each detection scan and around each dispatched job. Manual shell operations now wait for at most one in-flight job. The admin UI detect+execute path stops wrapping dispatch in an outer hold, since a nested acquire would deadlock against the lock manager's fairness window; detection and per-job dispatch take the lock themselves. * admin/plugin: stop extending the dispatch window to the largest job estimate When any proposal's estimated runtime exceeded the remaining JobTypeMaxRuntime, the whole dispatch context was replaced with a fresh one capped at eight hours, so a single balance backlog could hold the default lane (and with it erasure_coding and vacuum detection) for that long. Keep the dispatch window at JobTypeMaxRuntime and instead detach each started attempt onto its own estimated-runtime deadline. Large jobs still get their full time once started; jobs not yet started when the window closes are canceled and re-proposed by a later detection, so sibling job types get a turn every window. * worker/balance: re-check each planned move against the master before executing A balance plan is computed at detection time, but the admin lock is released between detection and execution, so a manual shell operation can rearrange the volume in the gap. The task's own guards catch a vanished source, but a target that gained a replica in the meantime would be silently overwritten by VolumeCopy and the source delete would then reduce the volume to a single copy. Before executing each move, ask the master for the volume's current locations (uncached) and skip the move if the volume has left the source or the target already holds a replica. Skipped moves fail with a stale-move error and the next detection replans them. Without master addresses in the cluster context the check is skipped, preserving the old behavior with older admins. * admin: block re-acquire while the final lock release is in flight Release dropped the manager mutex before calling ReleaseLock, so a concurrent Acquire could see hold count zero and call RequestLock while the locker still considered itself locked. That request no-ops, leaving a hold with no live master lease. Track the in-flight release and make Acquire wait for it. Also normalize a nil release function from lock manager implementations, and make the yield and fairness windows per-instance fields so tests stop mutating globals.	2026-07-09 20:43:55 -07:00
Chris LuandGitHub	884b0bcbfd	feat(s3/lifecycle): cluster rate-limit allocation (Phase 3) (#9456) ... * feat(s3/lifecycle): cluster rate-limit allocation (Phase 3) Admin computes a per-worker share of cluster_deletes_per_second at ExecuteJob time and ships it to the worker via ClusterContext.Metadata. The worker reads the share, constructs a golang.org/x/time/rate.Limiter, and passes it to dailyrun.Run via cfg.Limiter (Phase 2 already plumbed the field). Phase 5 deletes the streaming path; until then streaming ignores the cap. Why allocate at admin: the cluster cap is a single knob operators care about. Dividing it locally per worker would either need out-of-band coordination or accept N× the configured budget. Admin is the only party that knows how many execute-capable workers there are, so it owns the math. Admin side (weed/admin/plugin): - Registry.CountCapableExecutors(jobType) returns the number of non-stale workers with CanExecute=true. - New file cluster_rate_limit.go: decorateClusterContextForJob clones the input ClusterContext and injects two metadata keys for s3_lifecycle. cloneClusterContext duplicates Metadata so per-job decoration doesn't race shared base state. - executeJobWithExecutor calls the decorator after loading the admin config; other job types pass through unchanged. Worker side (weed/worker/tasks/s3_lifecycle): - New cluster_rate_limit.go declares the constants both sides agree on (admin-config field names, metadata keys). Plain strings on the admin side keep weed/admin/plugin free of a dependency on the s3_lifecycle worker package; the two sets of constants are pinned to identical values and a mismatch would silently disable rate limiting. - handler.go executeDailyReplay reads ClusterContext.Metadata, builds a rate.Limiter, and passes it into dailyrun.Config{Limiter}. Missing/empty/non-positive values → no limiter (legacy unlimited behavior). burst defaults to 2 × rate, clamped to ≥1 to avoid a bucket that never refills. - Admin form gains two fields under "Scope": cluster_deletes_per_second (rate, 0 = unlimited) and cluster_deletes_burst (0 = 2 × rate). Metric: - New S3LifecycleDispatchLimiterWaitSeconds histogram observes how long each Limiter.Wait blocks before a LifecycleDelete RPC. Operators tune the cap by reading p95 — near-zero means the cap isn't binding, a long tail at 1/rate means it is. Tests: - weed/admin/plugin/cluster_rate_limit_test.go: 9 cases covering pass-through for non-allocator job types, rps=0 / no-executors skip, even sharing, burst sharing, burst=0 omit (worker default kicks in), burst floor of 1, no mutation of input metadata, nil input. - weed/worker/tasks/s3_lifecycle/cluster_rate_limit_test.go: 7 cases covering nil/empty/missing metadata, non-positive/invalid rate, positive rate builds correctly, burst missing defaults to 2× rate, tiny rate clamps burst to ≥1. Build clean. Phase 2 (#9446) and Phase 4 engine (#9447) are the parents; this branch stacks on Phase 2 since it consumes dailyrun.Config{Limiter} which lands there. * fix(s3/lifecycle): divide cluster budget by active workers, not all capable gemini pointed out that s3_lifecycle has MaxJobsPerDetection=1 (handler.go:189) — it's a singleton job, only one worker is ever active. Dividing the cluster_deletes_per_second budget by the count of capable executors gave the single active worker just 1/N of the configured cap. Pass adminRuntime.MaxJobsPerDetection through to the decorator. Divisor is now min(executors, maxJobsPerDetection), clamped to >=1. For s3_lifecycle (maxJobs=1) the active worker gets the full budget; for a hypothetical parallel-dispatch job (maxJobs>1) the budget divides across the running-set. Tests swap the SharedEvenly case for two pinned scenarios: - SingletonJobGetsFullBudget: maxJobs=1 across 4 executors => 100/1 - SharedEvenlyWhenParallelLimited: maxJobs=4 across 4 executors => 25/worker - MaxJobsExceedsExecutors: maxJobs=10 across 4 executors => divisor 4 * feat(s3/lifecycle): drop Worker Count knob from admin config form The "Worker Count" admin field controlled in-process pipeline goroutines across the 16-shard space — per-worker tuning, not a cluster-wide scope concern. Operators looking at the form alongside Cluster Delete Rate reasonably misread it as the number of workers in the cluster. Drop the form field and DefaultValues entry. cfg.Workers is now hardcoded to shardPipelineGoroutines (=1) inside ParseConfig; the rest of the plumbing through dailyrun.Config.Workers stays so a future need can re-introduce it as a worker-local knob (or just bump the constant). handler_test.go pins that "workers" must NOT appear in the form so the removal doesn't silently regress.	2026-05-11 19:17:06 -07:00
Chris LuandGitHub	5d43f84df7	refactor(plugin): rename detection_interval_seconds → detection_interval_minutes (#9366) ... Minutes is the natural granularity for detection cadence — every production handler already set the seconds field to a 60-multiple (17*60, 30*60, 3600, 24*60*60). Switching to minutes drops the *60 arithmetic and matches the unit conventions used elsewhere in the plugin worker forms. - Proto: AdminRuntimeDefaults + AdminRuntimeConfig.detection_interval_* field renamed. - Helpers: durationFromMinutes / minutesFromDuration alongside the existing seconds variants in plugin_scheduler.go. - Handlers: vacuum, ec_balance, balance, erasure_coding, iceberg, admin_script, s3_lifecycle now declare DetectionIntervalMinutes. - Admin: scheduler_status + types + UI templ + plugin_api.go pass through the new field; UI label and table cells switch to "min".	2026-05-08 10:33:02 -07:00
Chris LuandGitHub	ae08e77979	fix(scheduler): give worker tasks a real per-attempt execution deadline (#9041) ... * fix(scheduler): give worker tasks a real per-attempt execution deadline The plugin scheduler derived the per-attempt execution deadline as DetectionTimeoutSeconds * 2, which capped every worker task at twice the cluster-scan budget regardless of actual work. For volume_balance batches this was 240s — far too short for 20 large volume copies, so every attempt died at "context deadline exceeded" and all in-flight sub-RPCs surfaced as "context canceled". Retries restarted from move 1 and hit the same wall. Add an explicit ExecutionTimeoutSeconds field to the plugin proto and make each handler declare its own baseline (1800s for vacuum, balance, EC; 3600s for iceberg). Size-aware handlers also emit an estimated_runtime_seconds parameter on each proposal so the scheduler extends the per-attempt deadline based on actual workload: - volume_balance batch: max(largest single move, total / concurrency) at 5 min/GB, so a skewed batch with one big volume isn't averaged away. - volume_balance single, vacuum (already), erasure_coding (10 min/GB), ec_balance (5 min/GB): per-volume budgets. admin_script and iceberg keep the configurable handler default since their workloads are opaque to the detector. * fix(scheduler): apply descriptor defaults to existing persisted configs The previous commit added execution_timeout_seconds to the proto and each handler's descriptor defaults, but two paths still left existing deployments broken: 1. deriveSchedulerAdminRuntime returned stored AdminRuntime configs as-is. Persisted configs from older versions have no execution_timeout_seconds, so the scheduler fell back to the 90s default — worse than the prior 240s behavior. Overlay descriptor defaults for any zero numeric fields when loading. 2. The admin form did not round-trip execution_timeout_seconds, so a normal save would clear it back to zero. Add the input field, the fillAdminSettings/collectAdminSettings hooks, and as defense in depth reapply descriptor defaults in UpdatePluginJobTypeConfigAPI before persisting so a stale form can never silently clobber a baseline. * fix(volume_balance): account for partial scheduling rounds in batch estimate With N moves and C slots, the busiest slot processes ceil(N/C) moves, not N/C. Dividing total seconds by C underestimates wall-clock time whenever N is not a multiple of C — e.g. 6 moves at concurrency 5 needs 2 rounds, not 1.2. Use avg * ceil(N/C) so partial rounds are counted as full ones. * fix(volume_balance): scale minBudget per wave instead of per move Orchestration overhead (setup/teardown for the parallel move runner) happens once per wave, not once per move. Use numRounds*60 as the floor instead of len(moves)*60 so the minimum doesn't inflate linearly with batch size when individual moves are tiny.	2026-04-13 01:15:53 -07:00

Major removals: - weed/filer/redis_lua: entire unused Redis Lua filer store implementation - weed/wdclient/net2, resource_pool: unused connection/resource pool packages - weed/plugin/worker/lifecycle: unused lifecycle plugin worker - weed/s3api: unused S3 policy templates, presigned URL IAM, streaming copy, multipart IAM, key rotation, and various SSE helper functions - weed/mq/kafka: unused partition mapping, compression, schema, and protocol functions - weed/mq/offset: unused SQL storage and migration code - weed/worker: unused registry, task, and monitoring functions - weed/query: unused SQL engine, parquet scanner, and type functions - weed/shell: unused EC proportional rebalance functions - weed/storage/erasure_coding/distribution: unused distribution analysis functions - Individual unreachable functions removed from 150+ files across admin, credential, filer, iam, kms, mount, mq, operation, pb, s3api, server, shell, storage, topology, and util packages * fix(s3): reset shared memory store in IAM test to prevent flaky failure TestLoadIAMManagerFromConfig_EmptyConfigWithFallbackKey was flaky because the MemoryStore credential backend is a singleton registered via init(). Earlier tests that create anonymous identities pollute the shared store, causing LookupAnonymous() to unexpectedly return true. Fix by calling Reset() on the memory store before the test runs. * style: run gofmt on changed files * fix: restore KMS functions used by integration tests * fix(plugin): prevent panic on send to closed worker session channel The Plugin.sendToWorker method could panic with "send on closed channel" when a worker disconnected while a message was being sent. The race was between streamSession.close() closing the outgoing channel and sendToWorker writing to it concurrently. Add a done channel to streamSession that is closed before the outgoing channel, and check it in sendToWorker's select to safely detect closed sessions without panicking.	2026-04-03 16:04:27 -07:00
3 people	d95df76bca	feat: separate scheduler lanes for iceberg, lifecycle, and volume management (#8787) ... * feat: introduce scheduler lanes for independent per-workload scheduling Split the single plugin scheduler loop into independent per-lane goroutines so that volume management, iceberg compaction, and lifecycle operations never block each other. Each lane has its own: - Goroutine (laneSchedulerLoop) - Wake channel for immediate scheduling - Admin lock scope (e.g. "plugin scheduler:default") - Configurable idle sleep duration - Loop state tracking Three lanes are defined: - default: vacuum, volume_balance, ec_balance, erasure_coding, admin_script - iceberg: iceberg_maintenance - lifecycle: s3_lifecycle (new, handler coming in a later commit) Job types are mapped to lanes via a hardcoded map with LaneDefault as the fallback. The SchedulerJobTypeState and SchedulerStatus types now include a Lane field for API consumers. * feat: per-lane execution reservation pools for resource isolation Each scheduler lane now maintains its own execution reservation map so that a busy volume lane cannot consume execution slots needed by iceberg or lifecycle lanes. The per-lane pool is used by default when dispatching jobs through the lane scheduler; the global pool remains as a fallback for the public DispatchProposals API. * feat: add per-lane scheduler status API and lane worker UI pages - GET /api/plugin/lanes returns all lanes with status and job types - GET /api/plugin/workers?lane=X filters workers by lane - GET /api/plugin/scheduler-states?lane=X filters job types by lane - GET /api/plugin/scheduler-status?lane=X returns lane-scoped status - GET /plugin/lanes/{lane}/workers renders per-lane worker page - SchedulerJobTypeState now includes a "lane" field The lane worker pages show scheduler status, job type configuration, and connected workers scoped to a single lane, with links back to the main plugin overview. * feat: add s3_lifecycle worker handler for object store lifecycle management Implements a full plugin worker handler for S3 lifecycle management, assigned to the new "lifecycle" scheduler lane. Detection phase: - Reads filer.conf to find buckets with TTL lifecycle rules - Creates one job proposal per bucket with active lifecycle rules - Supports bucket_filter wildcard pattern from admin config Execution phase: - Walks the bucket directory tree breadth-first - Identifies expired objects by checking TtlSec + Crtime < now - Deletes expired objects in configurable batches - Reports progress with scanned/expired/error counts - Supports dry_run mode for safe testing Configurable via admin UI: - batch_size: entries per filer listing page (default 1000) - max_deletes_per_bucket: safety cap per run (default 10000) - dry_run: detect without deleting - delete_marker_cleanup: clean expired delete markers - abort_mpu_days: abort stale multipart uploads The handler integrates with the existing PutBucketLifecycle flow which sets TtlSec on entries via filer.conf path rules. * feat: add per-lane submenu items under Workers sidebar menu Replace the single "Workers" sidebar link with a collapsible submenu containing three lane entries: - Default (volume management + admin scripts) -> /plugin - Iceberg (table compaction) -> /plugin/lanes/iceberg/workers - Lifecycle (S3 object expiration) -> /plugin/lanes/lifecycle/workers The submenu auto-expands when on any /plugin page and highlights the active lane. Icons match each lane's job type descriptor (server, snowflake, hourglass). * feat: scope plugin pages to their scheduler lane The plugin overview, configuration, detection, queue, and execution pages now filter workers, job types, scheduler states, and scheduler status to only show data for their lane. - Plugin() templ function accepts a lane parameter (default: "default") - JavaScript appends ?lane= to /api/plugin/workers, /job-types, /scheduler-states, and /scheduler-status API calls - GET /api/plugin/job-types now supports ?lane= filtering - When ?job= is provided (e.g. ?job=iceberg_maintenance), the lane is auto-derived from the job type so the page scopes correctly This ensures /plugin shows only default-lane workers and /plugin/configuration?job=iceberg_maintenance scopes to the iceberg lane. * fix: remove "Lane" from lane worker page titles and capitalize properly "lifecycle Lane Workers" -> "Lifecycle Workers" "iceberg Lane Workers" -> "Iceberg Workers" * refactor: promote lane items to top-level sidebar menu entries Move Default, Iceberg, and Lifecycle from a collapsible submenu to direct top-level items under the WORKERS heading. Removes the intermediate "Workers" parent link and collapse toggle. * admin: unify plugin lane routes and handlers * admin: filter plugin jobs and activities by lane * admin: reuse plugin UI for worker lane pages * fix: use ServerAddress.ToGrpcAddress() for filer connections in lifecycle handler ClusterContext addresses use ServerAddress format (host:port.grpcPort). Convert to the actual gRPC address via ToGrpcAddress() before dialing, and add a Ping verification after connecting. Fixes: "dial tcp: lookup tcp/8888.18888: unknown port" * fix: resolve ServerAddress gRPC port in iceberg and lifecycle filer connections ClusterContext addresses use ServerAddress format (host:httpPort.grpcPort). Both the iceberg and lifecycle handlers now detect the compound format and extract the gRPC port via ToGrpcAddress() before dialing. Plain host:port addresses (e.g. from tests) are passed through unchanged.

4 people	8cde3d4486	Add data file compaction to iceberg maintenance (Phase 2) (#8503) ... * Add iceberg_maintenance plugin worker handler (Phase 1) Implement automated Iceberg table maintenance as a new plugin worker job type. The handler scans S3 table buckets for tables needing maintenance and executes operations in the correct Iceberg order: expire snapshots, remove orphan files, and rewrite manifests. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Add data file compaction to iceberg maintenance handler (Phase 2) Implement bin-packing compaction for small Parquet data files: - Enumerate data files from manifests, group by partition - Merge small files using parquet-go (read rows, write merged output) - Create new manifest with ADDED/DELETED/EXISTING entries - Commit new snapshot with compaction metadata Add 'compact' operation to maintenance order (runs before expire_snapshots), configurable via target_file_size_bytes and min_input_files thresholds. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Fix memory exhaustion in mergeParquetFiles by processing files sequentially Previously all source Parquet files were loaded into memory simultaneously, risking OOM when a compaction bin contained many small files. Now each file is loaded, its rows are streamed into the output writer, and its data is released before the next file is loaded — keeping peak memory proportional to one input file plus the output buffer. * Validate bucket/namespace/table names against path traversal Reject names containing '..', '/', or '\' in Execute to prevent directory traversal via crafted job parameters. * Add filer address failover in iceberg maintenance handler Try each filer address from cluster context in order instead of only using the first one. This improves resilience when the primary filer is temporarily unreachable. * Add separate MinManifestsToRewrite config for manifest rewrite threshold The rewrite_manifests operation was reusing MinInputFiles (meant for compaction bin file counts) as its manifest count threshold. Add a dedicated MinManifestsToRewrite field with its own config UI section and default value (5) so the two thresholds can be tuned independently. * Fix risky mtime fallback in orphan removal that could delete new files When entry.Attributes is nil, mtime defaulted to Unix epoch (1970), which would always be older than the safety threshold, causing the file to be treated as eligible for deletion. Skip entries with nil Attributes instead, matching the safer logic in operations.go. * Fix undefined function references in iceberg_maintenance_handler.go Use the exported function names (ShouldSkipDetectionByInterval, BuildDetectorActivity, BuildExecutorActivity) matching their definitions in vacuum_handler.go. * Remove duplicated iceberg maintenance handler in favor of iceberg/ subpackage The IcebergMaintenanceHandler and its compaction code in the parent pluginworker package duplicated the logic already present in the iceberg/ subpackage (which self-registers via init()). The old code lacked stale-plan guards, proper path normalization, CAS-based xattr updates, and error-returning parseOperations. Since the registry pattern (default "all") makes the old handler unreachable, remove it entirely. All functionality is provided by iceberg.Handler with the reviewed improvements. * Fix MinManifestsToRewrite clamping to match UI minimum of 2 The clamp reset values below 2 to the default of 5, contradicting the UI's advertised MinValue of 2. Clamp to 2 instead. * Sort entries by size descending in splitOversizedBin for better packing Entries were processed in insertion order which is non-deterministic from map iteration. Sorting largest-first before the splitting loop improves bin packing efficiency by filling bins more evenly. * Add context cancellation check to drainReader loop The row-streaming loop in drainReader did not check ctx between iterations, making long compaction merges uncancellable. Check ctx.Done() at the top of each iteration. * Fix splitOversizedBin to always respect targetSize limit The minFiles check in the split condition allowed bins to grow past targetSize when they had fewer than minFiles entries, defeating the OOM protection. Now bins always split at targetSize, and a trailing runt with fewer than minFiles entries is merged into the previous bin. * Add integration tests for iceberg table maintenance plugin worker Tests start a real weed mini cluster, create S3 buckets and Iceberg table metadata via filer gRPC, then exercise the iceberg.Handler operations (ExpireSnapshots, RemoveOrphans, RewriteManifests) against the live filer. A full maintenance cycle test runs all operations in sequence and verifies metadata consistency. Also adds exported method wrappers (testing_api.go) so the integration test package can call the unexported handler methods. * Fix splitOversizedBin dropping files and add source path to drainReader errors The runt-merge step could leave leading bins with fewer than minFiles entries (e.g. [80,80,10,10] with targetSize=100, minFiles=2 would drop the first 80-byte file). Replace the filter-based approach with an iterative merge that folds any sub-minFiles bin into its smallest neighbor, preserving all eligible files. Also add the source file path to drainReader error messages so callers can identify which Parquet file caused a read/write failure. * Harden integration test error handling - s3put: fail immediately on HTTP 4xx/5xx instead of logging and continuing - lookupEntry: distinguish NotFound (return nil) from unexpected RPC errors (fail the test) - writeOrphan and orphan creation in FullMaintenanceCycle: check CreateEntryResponse.Error in addition to the RPC error * go fmt --------- Co-authored-by: Copilot <copilot@github.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>	2026-03-15 11:27:42 -07:00
Chris LuandGitHub	baae672b6f	feat: auto-disable master vacuum when plugin worker is active (#8624) ... * feat: auto-disable master vacuum when plugin vacuum worker is active When a vacuum-capable plugin worker connects to the admin server, the admin server calls DisableVacuum on the master to prevent the automatic scheduled vacuum from conflicting with the plugin worker's vacuum. When the worker disconnects, EnableVacuum is called to restore the default behavior. A safety net in the topology refresh loop re-enables vacuum if the admin server disconnects without cleanup. * rename isAdminServerConnected to isAdminServerConnectedFunc * add 5s timeout to DisableVacuum/EnableVacuum gRPC calls Prevents the monitor goroutine from blocking indefinitely if the master is unresponsive. * track plugin ownership of vacuum disable to avoid overriding operator - Add vacuumDisabledByPlugin flag to Topology, set when DisableVacuum is called while admin server is connected (i.e., by plugin monitor) - Safety net only re-enables vacuum when it was disabled by plugin, not when an operator intentionally disabled it via shell command - EnableVacuum clears the plugin flag * extract syncVacuumState for testability, add fake toggler tests Extract the single sync step into syncVacuumState() with a vacuumToggler interface. Add TestSyncVacuumState with a fake toggler that verifies disable/enable calls on state transitions. * use atomic.Bool for isDisableVacuum and vacuumDisabledByPlugin Both fields are written by gRPC handlers and read by the vacuum goroutine, causing a data race. Use atomic.Bool with Store/Load for thread-safe access. * use explicit by_plugin field instead of connection heuristic Add by_plugin bool to DisableVacuumRequest proto so the caller declares intent explicitly. The admin server monitor sets it to true; shell commands leave it false. This prevents an operator's intentional disable from being auto-reversed by the safety net. * use setter for admin server callback instead of function parameter Move isAdminServerConnected from StartRefreshWritableVolumes parameter to Topology.SetAdminServerConnectedFunc() setter. Keeps the function signature stable and decouples the topology layer from the admin server concept. * suppress repeated log messages on persistent sync failures Add retrying parameter to syncVacuumState so the initial state transition is logged at V(0) but subsequent retries of the same transition are silent until the call succeeds. * clear plugin ownership flag on manual DisableVacuum Prevents stale plugin flag from causing incorrect auto-enable when an operator manually disables vacuum after a plugin had previously disabled it. * add by_plugin to EnableVacuumRequest for symmetric ownership tracking Plugin-driven EnableVacuum now only re-enables if the plugin was the one that disabled it. If an operator manually disabled vacuum after the plugin, the plugin's EnableVacuum is a no-op. This prevents the plugin monitor from overriding operator intent on worker disconnect. * use cancellable context for monitorVacuumWorker goroutine Replace context.Background() with a cancellable context stored as bgCancel on AdminServer. Shutdown() calls bgCancel() so monitorVacuumWorker exits cleanly via ctx.Done(). * track operator and plugin vacuum disables independently Replace single isDisableVacuum flag with two independent flags: vacuumDisabledByOperator and vacuumDisabledByPlugin. Each caller only flips its own flag. The effective disabled state is the OR of both. This prevents a plugin connect/disconnect cycle from overriding an operator's manual disable, and vice versa. * fix safety net to clear plugin flag, not operator flag The safety net should call EnableVacuumByPlugin() to clear only the plugin disable flag when the admin server disconnects. The previous call to EnableVacuum() incorrectly cleared the operator flag instead.	2026-03-13 22:49:12 -07:00
Chris Lu	1bd7a98a4a	simplify plugin scheduler: remove configurable IdleSleepSeconds, use constant 61s ... The SchedulerConfig struct and its persistence/API were unnecessary indirection. Replace with a simple constant (reduced from 613s to 61s) so the scheduler re-checks for detectable job types promptly after going idle, improving the clean-install experience.	2026-03-09 22:41:03 -07:00
4 people	b3620c7e14	admin: auto migrating master maintenance scripts to admin_script plugin config (#8509) ... * admin: seed admin_script plugin config from master maintenance scripts When the admin server starts, fetch the maintenance scripts configuration from the master via GetMasterConfiguration. If the admin_script plugin worker does not already have a saved config, use the master's scripts as the default value. This enables seamless migration from master.toml [master.maintenance] to the admin script plugin worker. Changes: - Add maintenance_scripts and maintenance_sleep_minutes fields to GetMasterConfigurationResponse in master.proto - Populate the new fields from viper config in master_grpc_server.go - On admin server startup, fetch the master config and seed the admin_script plugin config if no config exists yet - Strip lock/unlock commands from the master scripts since the admin script worker handles locking automatically Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: address review comments on admin_script seeding - Replace TOCTOU race (separate Load+Save) with atomic SaveJobTypeConfigIfNotExists on ConfigStore and Plugin - Replace ineffective polling loop with single GetMaster call using 30s context timeout, since GetMaster respects context cancellation - Add unit tests for SaveJobTypeConfigIfNotExists (in-memory + on-disk) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: apply maintenance script defaults in gRPC handler The gRPC handler for GetMasterConfiguration read maintenance scripts from viper without calling SetDefault, relying on startAdminScripts having run first. If the admin server calls GetMasterConfiguration before startAdminScripts sets the defaults, viper returns empty strings and the seeding is silently skipped. Apply SetDefault in the gRPC handler itself so it is self-contained. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * Revert "fix: apply maintenance script defaults in gRPC handler" This reverts commit 068a506330. * fix: use atomic save in ensureJobTypeConfigFromDescriptor ensureJobTypeConfigFromDescriptor used a separate Load + Save, racing with seedAdminScriptFromMaster. If the descriptor defaults (empty script) were saved first, SaveJobTypeConfigIfNotExists in the seeding goroutine would see an existing config and skip, losing the master's maintenance scripts. Switch to SaveJobTypeConfigIfNotExists so both paths are atomic. Whichever wins, the other is a safe no-op. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: fetch master scripts inline during config bootstrap, not in goroutine Replace the seedAdminScriptFromMaster goroutine with a ConfigDefaultsProvider callback. When the plugin bootstraps admin_script defaults from the worker descriptor, it calls the provider which fetches maintenance scripts from the master synchronously. This eliminates the race between the seeding goroutine and the descriptor-based config bootstrap.
