Builds on merged PR-1 (#2729), independent of PR-2/PR-4. Implements every endpoint of the v1 plugin contract behind an HTTP server (cmd/memory-plugin-postgres/) backed by postgres. Operators run this binary next to workspace-server; it's the default implementation MEMORY_PLUGIN_URL points at. What ships: - cmd/memory-plugin-postgres/main.go: boot, signal-driven shutdown, boot-time migrations, configurable LISTEN/DATABASE/MIGRATION_DIR - cmd/memory-plugin-postgres/migrations/001_memory_v2.up.sql: memory_namespaces (PK on name, kind CHECK, expires_at, metadata) memory_records (FK to namespaces with CASCADE, kind+source CHECK, pgvector embedding, FTS tsvector, ivfflat partial index on embedding, partial index on expires_at) - internal/memory/pgplugin/store.go: storage layer using lib/pq - internal/memory/pgplugin/handlers.go: HTTP layer (no router dep — a switch on URL.Path keeps the binary's dep surface tiny) - 100% statement coverage on store.go + handlers.go Schema notes: - These tables live next to the plugin binary, NOT in workspace- server/migrations/. When operators swap the plugin, these tables become orphaned (operator drops manually). Documented in PR-10. - Search supports semantic (pgvector cosine) → FTS (>=2 char query) → ILIKE (1-char query) → recent-listing (no query), with a TTL filter applied uniformly across all paths. - DELETE on namespace cascades to memory_records (FK ON DELETE CASCADE) — a deleted namespace immediately frees its memories. Coverage corner cases pinned: - Health: ok, degraded (db ping fails), no-ping fn - Every CRUD endpoint: happy path, bad name, bad JSON, bad body, not-found, store errors, exec/scan/marshal errors - Search: FTS, semantic, short-query (ILIKE), no-query (recent), kinds filter, store errors, scan errors, mid-iteration row error - Routing edge cases: unknown path, empty namespace, unknown sub, method-not-allowed, GET on /v1/health (allowed), POST on /v1/health (404), GET on /v1/search (404) - Helper internals: marshalMetadata (nil/happy/unmarshalable), nullTime (nil/non-nil), vectorString (empty/format), nullVectorString (empty/non-empty), scanNamespace + scanMemory metadata-decode errors No callers in workspace-server yet; integration starts in PR-5 (MCP handlers wire the plugin client through to MCP tools). |
