Chris Lu 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* seaweed-worker: run rustfmt over the workspace

Committed the crates unformatted, so `cargo fmt --all --check` failed on
files nothing had touched since.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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.

* 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 Lu 17af32f3ff s3: paginate ListBuckets and serve it from a bucket owner index (#10214)
* s3: paginate ListBuckets with max-buckets, continuation-token, and prefix

ListBuckets buffered every bucket entry into one slice and one XML body,
which falls over with very large bucket counts. Page through the filer
listing instead, cap each response at 10000 buckets like AWS, and honor
max-buckets, prefix, and an opaque keyset continuation-token.

* s3: maintain a bucket owner index under /buckets/.system/owners

Map each bucket owner to its buckets as zero-length entries at
/buckets/.system/owners/<owner>/<bucket>, with Crtime mirroring the
bucket's creation time. The bucket handlers write the index
synchronously, the /buckets metadata subscription reconciles changes
made elsewhere (weed shell, other gateways, direct filer operations),
and a startup backfill indexes pre-existing buckets before writing a
ready marker. Owner names are path-escaped so no identity name can
escape the index directory.

* s3: serve ListBuckets from the bucket owner index

Once the owner index is ready, non-admin identities list their owned
buckets straight from it, merged with any buckets their legacy actions
name explicitly, so ListBuckets costs O(own buckets) instead of a scan
of the global /buckets directory. Admins, identities with a bare List
grant or wildcard action patterns, and policy-authorized identities
whose grants cannot be enumerated keep the paged scan; policy-routed
identities get their owned buckets, matching AWS ListBuckets returning
only the caller's buckets.

* s3: keep dot-prefixed names under /buckets out of bucket surfaces

Dot-prefixed entries (.system) can never be valid bucket names, so
refuse to resolve them as buckets and skip them in the shell bucket
listing, matching what ListBuckets and the admin UI already do.

* test: cover ListBuckets pagination and the owner index end to end

* s3: fail closed on a nil identity when routing ListBuckets

* s3: decide the IAM authorization mechanism in one place

VerifyActionPermission and the ListBuckets owner-index routing each
re-derived the session-token / attached-policy / legacy-actions split;
extract the decision so the two cannot drift.

* s3: heal the owner index on concurrent bucket recreation too

The mkdir-lost-the-race path answers BucketAlreadyOwnedByYou just like
the up-front existence check, so give it the same index repair.

* s3: drop owner-index records for buckets deleted during backfill

A bucket removed between the backfill reading its page and writing the
index record became a permanent phantom in its owner's listing: the
delete's own cleanup ran before the record existed. After indexing each
page, re-list the same name range and remove records whose bucket is
gone; deletes landing after the re-list find the record and remove it
themselves.

* s3: add ContinuationToken and Prefix to the ListBuckets schema

Keep AmazonS3.xsd aligned with the generated ListAllMyBucketsResult so
a regeneration does not drop the pagination fields.

Chris Lu c4f0b12a9a s3: lazy, bounded, entry-free per-bucket caches (#10213)
* s3: stop warming every bucket's config at startup

Listing all buckets in BucketRegistry.init() made S3 gateway startup
O(buckets) and pinned every bucket's metadata and config resident, which
does not scale past a few hundred thousand buckets. Both caches already
have lazy miss paths, so load on first access instead and let the
metadata subscription refresh only entries already resident; cold
buckets cost one filer round-trip on their first request.

* s3: bound the per-bucket caches with LRU eviction

The bucket config cache, bucket registry, and their negative caches were
plain maps that only ever grew: the config cache TTL made Get miss but
never evicted the entry, and the not-found sets grew on every probe of a
nonexistent bucket name. Cap all four at 65536 entries with LRU eviction
so a gateway keeps its hot working set and evicted buckets reload from
the filer on next access.

* s3: cache parsed bucket config instead of the full filer entry

Each cached BucketConfig retained the whole bucket entry (extended
attribute map plus raw content bytes) alongside the fields parsed from
it, roughly doubling per-bucket cache cost and keeping data the read
path never looks at. Parse everything up front in
newBucketConfigFromEntry - now also the creator identity, tags,
encryption config, and stored lifecycle XML - and drop the entry.

updateBucketConfig now reads the entry fresh from the filer and diffs
the mapped extended attributes against it, so the patch is computed
against current state instead of a cached copy; the config clone
helpers that existed for that path go away.

* s3: dedup cold bucket-registry loads per bucket

The registry's notFound lock doubled as the load serializer, holding one
global mutex across the filer round-trip so first-touch requests for
different buckets queued behind each other; the cache fill also happened
after the lock was released, so two concurrent misses for the same
bucket could both reach the filer. Replace it with a singleflight per
bucket that fills the cache inside the flight: different buckets load
concurrently, the same bucket loads once.

Chris Lu 8eba7ba5b2 feat: drop table location mapping support (#8458)
* feat: drop table location mapping support

Disable external metadata locations for S3 Tables and remove the table location
mapping index entirely. Table metadata must live under the table bucket paths,
so lookups no longer use mapping directories.

Changes:
- Remove mapping lookup and cache from bucket path resolution
- Reject metadataLocation in CreateTable and UpdateTable
- Remove mapping helpers and tests

* compile

* refactor

* fix: accept metadataLocation in S3 Tables API requests

We removed the external table location mapping feature, but still need to
accept and store metadataLocation values from clients like Trino. The mapping
feature was an internal implementation detail that mapped external buckets to
internal table paths. The metadataLocation field itself is part of the S3 Tables
API and should be preserved.

* fmt

* fix: handle MetadataLocation in UpdateTable requests

Mirror handleCreateTable behavior by updating metadata.MetadataLocation
when req.MetadataLocation is provided in UpdateTable requests. This ensures
table metadata location can be updated, not just set during creation.

Chris Lu 641351da78 fix: table location mappings to /etc/s3tables (#8457)
* fix: move table location mappings to /etc/s3tables to avoid bucket name validation

Fixes #8362 - table location mappings were stored under /buckets/.table-location-mappings
which fails bucket name validation because it starts with a dot. Moving them to
/etc/s3tables resolves the migration error for upgrades.

Changes:
- Table location mappings now stored under /etc/s3tables
- Ensure parent /etc directory exists before creating /etc/s3tables
- Normal writes go to new location only (no legacy compatibility)
- Removed bucket name validation exception for old location

* refactor: simplify lookupTableLocationMapping by removing redundant mappingPath parameter

The mappingPath function parameter was redundant as the path can be derived
from mappingDir and bucket using path.Join. This simplifies the code and
reduces the risk of path mismatches between parameters.

Chris Lu 5a0204310c Add Iceberg admin UI (#8246)
* Add Iceberg table details view

* Enhance Iceberg catalog browsing UI

* Fix Iceberg UI security and logic issues

- Fix selectSchema() and partitionFieldsFromFullMetadata() to always search for matching IDs instead of checking != 0
- Fix snapshotsFromFullMetadata() to defensive-copy before sorting to prevent mutating caller's slice
- Fix XSS vulnerabilities in s3tables.js: replace innerHTML with textContent/createElement for user-controlled data
- Fix deleteIcebergTable() to redirect to namespace tables list on details page instead of reloading
- Fix data-bs-target in iceberg_namespaces.templ: remove templ.SafeURL for CSS selector
- Add catalogName to delete modal data attributes for proper redirect
- Remove unused hidden inputs from create table form (icebergTableBucketArn, icebergTableNamespace)

* Regenerate templ files for Iceberg UI updates

* Support complex Iceberg type objects in schema

Change Type field from string to json.RawMessage in both IcebergSchemaFieldInfo
and internal icebergSchemaField to properly handle Iceberg spec's complex type
objects (e.g. {"type": "struct", "fields": [...]}). Currently test data
only shows primitive string types, but this change makes the implementation
defensively robust for future complex types by preserving the exact JSON
representation. Add typeToString() helper and update schema extraction
functions to marshal string types as JSON. Update template to convert
json.RawMessage to string for display.

* Regenerate templ files for Type field changes

* templ

* Fix additional Iceberg UI issues from code review

- Fix lazy-load flag that was set before async operation completed, preventing retries
  on error; now sets loaded flag only after successful load and throws error to caller
  for proper error handling and UI updates
- Add zero-time guards for CreatedAt and ModifiedAt fields in table details to avoid
  displaying Go zero-time values; render dash when time is zero
- Add URL path escaping for all catalog/namespace/table names in URLs to prevent
  malformed URLs when names contain special characters like /, ?, or #
- Remove redundant innerHTML clear in loadIcebergNamespaceTables that cleared twice
  before appending the table list
- Fix selectSnapshotForMetrics to remove != 0 guard for consistency with selectSchema
  fix; now always searches for CurrentSnapshotID without zero-value gate
- Enhance typeToString() helper to display '(complex)' for non-primitive JSON types

* Regenerate templ files for Phase 3 updates

* Fix template generation to use correct file paths

Run templ generate from repo root instead of weed/admin directory to ensure
generated _templ.go files have correct absolute paths in error messages
(e.g., 'weed/admin/view/app/iceberg_table_details.templ' instead of
'app/iceberg_table_details.templ'). This ensures both 'make admin-generate'
at repo root and 'make generate' in weed/admin directory produce identical
output with consistent file path references.

* Regenerate template files with correct path references

* Validate S3 Tables names in UI

- Add client-side validation for table bucket and namespace names to surface
  errors for invalid characters (dots/underscores) before submission
- Use HTML validity messages with reportValidity for immediate feedback
- Update namespace helper text to reflect actual constraints (single-level,
  lowercase letters, numbers, and underscores)

* Regenerate templ files for namespace helper text

* Fix Iceberg catalog REST link and actions

* Disallow S3 object access on table buckets

* Validate Iceberg layout for table bucket objects

* Fix REST API link to /v1/config

* merge iceberg page with table bucket page

* Allowed Trino/Iceberg stats files in metadata validation

Chris Lu 403592bb9f Add Spark Iceberg catalog integration tests and CI support (#8242)
* Add Spark Iceberg catalog integration tests and CI support

Implement comprehensive integration tests for Spark with SeaweedFS Iceberg REST catalog:
- Basic CRUD operations (Create, Read, Update, Delete) on Iceberg tables
- Namespace (database) management
- Data insertion, querying, and deletion
- Time travel capabilities via snapshot versioning
- Compatible with SeaweedFS S3 and Iceberg REST endpoints

Tests mirror the structure of existing Trino integration tests but use Spark's
Python SQL API and PySpark for testing.

Add GitHub Actions CI job for spark-iceberg-catalog-tests in s3-tables-tests.yml
to automatically run Spark integration tests on pull requests.

* fmt

* Fix Spark integration tests - code review feedback

* go mod tidy

* Add go mod tidy step to integration test jobs

Add 'go mod tidy' step before test runs for all integration test jobs:
- s3-tables-tests
- iceberg-catalog-tests
- trino-iceberg-catalog-tests
- spark-iceberg-catalog-tests

This ensures dependencies are clean before running tests.

* Fix remaining Spark operations test issues

Address final code review comments:

Setup & Initialization:
- Add waitForSparkReady() helper function that polls Spark readiness
  with backoff instead of hardcoded 10-second sleep
- Extract setupSparkTestEnv() helper to reduce boilerplate duplication
  between TestSparkCatalogBasicOperations and TestSparkTimeTravel
- Both tests now use helpers for consistent, reliable setup

Assertions & Validation:
- Make setup-critical operations (namespace, table creation, initial
  insert) use t.Fatalf instead of t.Errorf to fail fast
- Validate setupSQL output in TestSparkTimeTravel and fail if not
  'Setup complete'
- Add validation after second INSERT in TestSparkTimeTravel:
  verify row count increased to 2 before time travel test
- Add context to error messages with namespace and tableName params

Code Quality:
- Remove code duplication between test functions
- All critical paths now properly validated
- Consistent error handling throughout

* Fix go vet errors in S3 Tables tests

Fixes:
1. setup_test.go (Spark):
   - Add missing import: github.com/testcontainers/testcontainers-go/wait
   - Use wait.ForLog instead of undefined testcontainers.NewLogStrategy
   - Remove unused strings import

2. trino_catalog_test.go:
   - Use net.JoinHostPort instead of fmt.Sprintf for address formatting
   - Properly handles IPv6 addresses by wrapping them in brackets

* Use weed mini for simpler SeaweedFS startup

Replace complex multi-process startup (master, volume, filer, s3)
with single 'weed mini' command that starts all services together.

Benefits:
- Simpler, more reliable startup
- Single weed mini process vs 4 separate processes
- Automatic coordination between components
- Better port management with no manual coordination

Changes:
- Remove separate master, volume, filer process startup
- Use weed mini with -master.port, -filer.port, -s3.port flags
- Keep Iceberg REST as separate service (still needed)
- Increase timeout to 15s for port readiness (weed mini startup)
- Remove volumePort and filerProcess fields from TestEnvironment
- Simplify cleanup to only handle two processes (mini, iceberg rest)

* Clean up dead code and temp directory leaks

Fixes:

1. Remove dead s3Process field and cleanup:
   - weed mini bundles S3 gateway, no separate process needed
   - Removed s3Process field from TestEnvironment
   - Removed unnecessary s3Process cleanup code

2. Fix temp config directory leak:
   - Add sparkConfigDir field to TestEnvironment
   - Store returned configDir in writeSparkConfig
   - Clean up sparkConfigDir in Cleanup() with os.RemoveAll
   - Prevents accumulation of temp directories in test runs

3. Simplify Cleanup:
   - Now handles only necessary processes (weed mini, iceberg rest)
   - Removes both seaweedfsDataDir and sparkConfigDir
   - Cleaner shutdown sequence

* Use weed mini's built-in Iceberg REST and fix python binary

Changes:
- Add -s3.port.iceberg flag to weed mini for built-in Iceberg REST Catalog
- Remove separate 'weed server' process for Iceberg REST
- Remove icebergRestProcess field from TestEnvironment
- Simplify Cleanup() to only manage weed mini + Spark
- Add port readiness check for iceberg REST from weed mini
- Set Spark container Cmd to '/bin/sh -c sleep 3600' to keep it running
- Change python to python3 in container.Exec calls

This simplifies to truly one all-in-one weed mini process (master, filer, s3,
iceberg-rest) plus just the Spark container.

* go fmt

* clean up

* bind on a non-loopback IP for container access, aligned Iceberg metadata saves/locations with table locations, and reworked Spark time travel to use TIMESTAMP AS OF   with safe timestamp extraction.

* shared mini start

* Fixed internal directory creation under /buckets so .objects paths can auto-create without failing bucket-name validation, which restores table bucket object writes

* fix path

  Updated table bucket objects to write under `/buckets/<bucket>` and saved Iceberg metadata there, adjusting Spark time-travel timestamp to committed_at +1s. Rebuilt the weed binary (`go
  install ./weed`) and confirmed passing tests for Spark and Trino with focused test commands.

* Updated table bucket creation to stop creating /buckets/.objects and switched Trino REST warehouse to s3://<bucket> to match Iceberg layout.

* Stabilize S3Tables integration tests

* Fix timestamp extraction and remove dead code in bucketDir

* Use table bucket as warehouse in s3tables tests

* Update trino_blog_operations_test.go

* adds the CASCADE option to handle any remaining table metadata/files in the schema directory

* skip namespace not empty

* fix: improve cache invalidation and add transient error handling

Cache invalidation (critical fix):
- Add tableLocationCache to BucketRegistry for location mapping lookups
- Clear tableBucketCache and tableLocationCache in RemoveBucketMetadata
- Prevents stale cache entries when buckets are deleted/recreated

Transient error handling:
- Only cache table bucket lookups when conclusive (found or ErrNotFound)
- Skip caching on transient errors (network, permission, etc)
- Prevents marking real table buckets as non-table due to transient failures

Performance optimization:
- Cache tableLocationDir results to avoid repeated filer RPCs on hot paths
- tableLocationDir now checks cache before making expensive filer lookups
- Cache stores empty string for 'not found' to avoid redundant lookups

Code clarity:
- Add comment to deleteDirectory explaining DeleteEntry response lacks Error field

* go fmt

* fix: mirror transient error handling in tableLocationDir and optimize bucketDir

Transient error handling:
- tableLocationDir now only caches definitive results
- Mirrors isTableBucket behavior to prevent treating transient errors as permanent misses
- Improves reliability on flaky systems or during recovery

Performance optimization:
- bucketDir avoids redundant isTableBucket call via bucketRoot
- Directly use s3a.option.BucketsPath for regular buckets
- Saves one cache lookup for every non-table bucket operation

* fix: revert bucketDir optimization to preserve bucketRoot logic

The optimization to directly use BucketsPath bypassed bucketRoot's logic
and caused issues with S3 list operations on delimiter+prefix cases.

Revert to using path.Join(s3a.bucketRoot(bucket), bucket) which properly
handles all bucket types and ensures consistent path resolution across
the codebase.

The slight performance cost of an extra cache lookup is worth the correctness
and consistency benefits.

* feat: move table buckets under /buckets

Add a table-bucket marker attribute, reuse bucket metadata cache for table bucket detection, and update list/validation/UI/test paths to treat table buckets as /buckets entries.

* Fix S3 Tables code review issues

- handler_bucket_create.go: Fix bucket existence check to properly validate
  entryResp.Entry before setting s3BucketExists flag (nil Entry should not
  indicate existing bucket)
- bucket_paths.go: Add clarifying comment to bucketRoot() explaining unified
  buckets root path for all bucket types
- file_browser_data.go: Optimize by extracting table bucket check early to
  avoid redundant WithFilerClient call

* Fix list prefix delimiter handling

* Handle list errors conservatively

* Fix Trino FOR TIMESTAMP query - use past timestamp

Iceberg requires the timestamp to be strictly in the past.
Use current_timestamp - interval '1' second instead of current_timestamp.
