fix(s3tables/iceberg): make metadata spec-compliant and accept real-world manifest names (#9703)
* fix(s3tables/iceberg): make metadata spec-compliant and accept real-world manifest names
Two related issues prevent SeaweedFS S3 Tables from interoperating with
strict Iceberg clients (Java/Spark/Flink/Trino):
1. iceberg-go v0.5.0 serializes empty TableMetadata state by dropping
keys via `omitempty` on optional pointer/slice fields. The Iceberg
table spec, however, requires `current-snapshot-id`, `snapshots`,
`snapshot-log`, `metadata-log`, and `refs` to be present even when
empty (`current-snapshot-id` must be -1 for a table with no
snapshots). Java's TableMetadataParser uses JsonUtil.getLong on
`current-snapshot-id` and throws "Cannot parse missing long
current-snapshot-id" against responses produced by this server.
2. The Iceberg layout validator only accepts manifest filenames that
match Iceberg's internal naming (`{uuid}-m{n}.avro`,
`snap-{n}-{n}-{uuid}.avro`). Real writers — notably Flink's sink —
emit manifests like
`{flink-job-id}-{checkpoint}-{operator-id}-{n}.avro`, which the
validator rejects with 403, breaking INSERT commits.
Fixes:
* Add ensureMetadataSpecCompliance helper that backfills the five
spec-required empty-state fields when iceberg-go omits them or emits
explicit JSON null. Apply it on every code path that writes
v*.metadata.json to S3 or returns metadata to clients
(handlers_table create-table, handlers_commit, commit_helpers
create-on-commit, plus MarshalJSON on LoadTableResult and
CommitTableResponse). Real values from non-empty tables are never
overwritten.
* Add catch-all regex entries to metadataFilePatterns accepting any
*.avro / *.metadata.json filename composed of [A-Za-z0-9._-]. The
Iceberg spec does not mandate filename format; the strict patterns
remain for documentation. Metadata-directory subdirectory rejection
and the data-file path validation are unchanged.
No upstream dependencies are forked: iceberg-go stays at v0.5.0 and
go.mod is untouched. The compliance layer can be removed once upstream
emits spec-compliant output.
Tests (all pass under `go test -race`):
- metadata_compliance_test.go: 5 cases covering missing fields,
preserved real values, explicit null, invalid JSON, empty input.
- iceberg_layout_test.go: 3 groups (16 subtests) covering real-world
manifest names from Flink/Spark/Iceberg, security boundary
(subdirectories, bad extensions), and data-file regression.
* fix(s3tables/iceberg): preserve metadata key order and keep config field stable
Two small follow-ups on the spec-compliance fix:
* ensureMetadataSpecCompliance now splices missing keys in at the byte
level just before the closing brace, so iceberg-go's struct-declared
key order survives the backfill. The previous unmarshal/remarshal
through map[string]json.RawMessage silently alphabetized every key in
the document, which is spec-legal but breaks byte-equality fixtures
and any downstream hashing of the persisted metadata. The slower
remarshal path is kept for the rare explicit-null replacement case.
* LoadTableResult.MarshalJSON now serializes Config without omitempty,
matching the struct field tag. The custom marshaler had silently
flipped the tag to ,omitempty, which made the "config" key disappear
from the response whenever s3Endpoint was unset (since
buildFileIOConfig returned an empty but non-nil Properties map).
Tests:
- PreservesOriginalKeyOrder pins the byte-level output against
iceberg-go's emitted shape; would have caught the alphabetization
regression.
- EmptyObjectBackfilled covers the {} -> sentinels-only case (no
leading comma).
- AllPresentReturnsSameBytes confirms the no-op path returns input
bytes unchanged, with whitespace intact.
- iceberg_layout_test pins the catch-all $ anchor: metadata/file.avro.txt
must still be rejected.
* fix(s3tables/iceberg): guard ensureMetadataSpecCompliance against top-level null
json.Unmarshal of a JSON `null` literal succeeds but leaves the map nil.
The current byte-append path no-ops gracefully on this input, but the
slow remarshal path would panic with "assignment to entry in nil map"
if the input ever combined `null` with the explicit-null detection. Add
an explicit nil-map short-circuit so the safety property is obvious
from the source, and a test that pins the contract.
* test(s3tables/iceberg): assert full byte equality in AllPresentReturnsSameBytes
The prefix check only caught a missing "{\n " opener, so the test
would have passed even if the function silently reordered keys or
collapsed whitespace later in the document. Switch to a full string
comparison so any future regression in the no-op path is loud.

fix(iceberg): use dot separator for namespace paths instead of unit separator (#8960)
* fix(iceberg): use dot separator for namespace paths instead of unit separator The Iceberg REST Catalog handler was using \x1F (unit separator) to join multi-level namespaces when constructing S3 location and filer paths. The S3 Tables storage layer uses "." (dot) as the namespace separator, causing tables created via the Iceberg REST API to point to different paths than where S3 Tables actually stores them. Fixes #8959 * fix(iceberg): use dot separator in log messages for readable namespace output * fix(iceberg): use path.Join for S3 location path segments Use path.Join to construct the namespace/table path segments in fallback S3 locations for robustness and consistency with handleCreateTable. * test(iceberg): add multi-level namespace integration tests for Spark and Trino Add regression tests for #8959 that create a two-level namespace (e.g. "analytics.daily"), create a table under it, insert data, and query it back. This exercises the dot-separated namespace path construction and verifies that Spark/Trino can actually read the data at the S3 location returned by the Iceberg REST API. * fix(test): enable nested namespace in Trino Iceberg catalog config Trino requires `iceberg.rest-catalog.nested-namespace-enabled=true` to support multi-level namespaces. Without this, CREATE SCHEMA with a dotted name fails with "Nested namespace is not enabled for this catalog". * fix(test): parse Trino COUNT(*) output as integer instead of substring match Avoids false matches from strings.Contains(output, "3") by parsing the actual numeric result with strconv.Atoi and asserting equality. * fix(test): use separate Trino config for nested namespace test The nested-namespace-enabled=true setting in Trino changes how SHOW SCHEMAS works, causing "Internal error" for all tests sharing that catalog config. Move the flag to a dedicated config used only by TestTrinoMultiLevelNamespace. * fix(iceberg): support parent query parameter in ListNamespaces for nested namespaces Add handling for the Iceberg REST spec's `parent` query parameter in handleListNamespaces. When Trino has nested-namespace-enabled=true, it sends `GET /v1/namespaces?parent=<ns>` to list child namespaces. The parent value is decoded from the Iceberg unit separator format and converted to a dot-separated prefix for the S3 Tables layer. Also simplify TestTrinoMultiLevelNamespace to focus on namespace operations (create, list, show tables) rather than data operations, since Trino's REST catalog has a non-empty location check that conflicts with server-side metadata creation. * fix(test): expand Trino multi-level namespace test and merge config helpers - Expand TestTrinoMultiLevelNamespace to create a table with explicit location, insert rows, query them back, and verify the S3 file path contains the dot-separated namespace (not \x1F). This ensures the original #8959 bug would be caught by the Trino integration test. - Merge writeTrinoConfig and writeTrinoNestedNamespaceConfig into a single parameterized function using functional options. |

chore: remove ~50k lines of unreachable dead code (#8913)
* chore: remove unreachable dead code across the codebase Remove ~50,000 lines of unreachable code identified by static analysis. 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. |
