Add [features] section with integration = [] to warpgrid-host Cargo.toml for gating MySQL and Redis integration tests. Also fix pre-existing missing `wat` workspace dependency in root Cargo.toml. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Create wit/test.wit, wit/deps/shim/database-proxy.wit, and wit/deps/shim/dns.wit for the existing US-703 guest fixture that was missing its WIT directory. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Create tests/fixtures/rust-mysql-redis-integration-guest/ with: - Cargo.toml (cdylib, wit-bindgen 0.42, dlmalloc) - WIT world definition with 4 exported test functions - Full lib.rs implementing MySQL wire protocol helpers (handshake, COM_QUERY, OK/ERR/EOF parsing, length-encoded strings) and Redis RESP helpers (command builder, bulk string parser) Exports: test-mysql-crud, test-redis-crud, test-mysql-pool-reuse, test-redis-pool-reuse — all exercising raw protocol bytes through the database-proxy WIT interface. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Implement end-to-end integration tests proving Wasm guest components can communicate with MySQL and Redis through WarpGrid's database proxy. New test file: integration_wasm_mysql_redis.rs (gated behind cfg(feature = "integration")) with 6 tests: - test_mysql_crud_via_wasm: CREATE TABLE → INSERT → SELECT → DROP TABLE - test_redis_crud_via_wasm: SET → GET → DEL - test_mysql_pool_reuse_via_wasm: connect → query → close → reconnect → query - test_redis_pool_reuse_via_wasm: connect → SET → close → reconnect → GET - test_mysql_health_check_removes_dead: COM_PING detects dead connections - test_redis_health_check_removes_dead: PING detects dead connections Includes StatefulMockMysqlServer (SQL-aware query dispatch with state tracking) and StatefulMockRedisServer (RESP protocol with HashMap key-value state). All clippy warnings resolved. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
