Chris LuandDevin d15396fc4d s3tables: scope the anonymous identity's grant on the table catalogs (#12056)
* s3tables: scope the resolved anonymous identity instead of defaulting to allow

Catalog authorization fell back to the open default whenever the request
resolved to the configured anonymous identity, ignoring its grant. The
fallback now applies only when no principal was resolved (zero-config),
so anonymous requests are checked against the identity's configured
actions like any other principal. The S3 Tables API and the Iceberg and
Lance catalogs share this handler, so all three are covered.

* test: authenticate the catalog clients in the s3tables suites

Anonymous calls into the Lance and Iceberg catalogs are now scoped by
the anonymous identity's grant, so the suites that used to rely on the
anonymous pass authenticate like their real deployments do: x-api-key
for the Lance probes and REST drivers, client-credentials OAuth for
pyiceberg.

* worker(lance): authenticate namespace calls with the storage credential

Anonymous catalog calls are now scoped by the anonymous grant, so a
worker that holds an S3 credential sends it as x-api-key on the
namespace requests instead of relying on the anonymous pass.

* lance: follow catalog redirects only within the same host

reqwest forwards custom headers on a follow, so a redirect to another
host would carry the x-api-key credential to a server it was never
meant for. Keep same-host hops for proxies that normalize the path or
upgrade the scheme.

* lance: warn when the catalog api key travels in cleartext

The x-api-key pair is a real storage credential: over plain http to a
non-loopback host the network can read it. Warn at client build so the
operator sees it; https and loopback stay quiet, and the key still
sends since an http catalog is a valid deployment.

* lance: require the same origin on catalog redirects

A same-host hop can still downgrade https to http and put the api key on
the wire; matching scheme, host, and port keeps the credential on the
listener it was issued for.

* lance: bound catalog redirect hops so loops fail fast

The custom redirect policy drops reqwest's default 10-hop limit, so a
catalog that redirects back to itself would hold each call open until
the request timeout. Keep the bound alongside the origin check.

* lance: gofmt the redirect helpers

DuckDB Lance Integration Test

Reads SeaweedFS Lance tables from DuckDB's lance core extension, the counterpart of the DuckDB Iceberg tests in ../catalog/.

What this one proves that the others do not

The LanceDB and Spark suites go through the catalog. DuckDB does not: it reaches the data over S3 with no namespace involved. That exercises the other half of the design — a table bucket's layout is a valid Lance dataset directory, so a table stays readable when the catalog is not in the path.

What it does

TestDuckDBLance:

  1. Starts a weed mini cluster with S3 and the Lance Namespace enabled.
  2. Creates a table bucket declared LANCE, then declares a table through the namespace and writes a dataset into it with pylance.
  3. Runs duckdb_lance_ops.sql in duckdb/duckdb:latest.
Step What it proves
__lance_scan(s3://…) DuckDB reads a table this catalog created
DESCRIBE the schema survived, vector column included
WHERE id < 5 the filter path
lance_vector_search vector search over data behind SeaweedFS
a .lance path the replacement scan works on a suffixed path
a suffix-less path and does not see one without the suffix

The .lance suffix

DuckDB's replacement scan — SELECT * FROM 's3://…' — recognises a Lance dataset by a .lance path suffix. Tables created through this catalog deliberately have none: the catalog entry is the dataset directory, table names may not contain a dot, and a suffix would leak into ARNs and policies.

So from DuckDB, a table in a SeaweedFS table bucket is read with __lance_scan('s3://bucket/namespace/table') rather than the bare FROM 's3://…' form. The test asserts both halves, so if the extension ever recognises a suffix-less directory the test fails and tells us to update the documentation.

Credentials

CREATE SECRET seaweedfs (
    TYPE lance,
    ACCESS_KEY_ID '…', SECRET_ACCESS_KEY '…',
    REGION 'us-east-1',
    ENDPOINT 'http://seaweed:8333',
    ALLOW_HTTP true,
    VIRTUAL_HOSTED_STYLE_REQUEST false
);

Those are object_store's key names, the same as everywhere else Lance touches storage.

Running it

cd test/s3tables/catalog_duckdb_lance
(cd ../../../weed && go build .)     # the harness runs this binary
go test -run TestDuckDBLance -v -timeout 30m .

Skipped without Docker, in -short mode, and if the DuckDB image cannot load the extension.
