WASI ip-name-lookup support is +being added; SRV/TXT needs a native DNS capability or resolved seeds. ## Open questions and next steps -- Implement clients, SQL/CMAP pools, Redis routing/reconnect/Sentinel and MongoDB - monitoring/retries/cursors using shared transport glue. -- Add meaningful cancellation, real-server, allocation and no-spin tests, examples, - READMEs and required protocol/protocol-wasi CI metadata. -- Run native and cross-target gates.

Connection setup allocates buffers once. Dropping an +in-flight wire exchange closes it; the next pool lease can create a replacement. +Cursor drop queues best-effort kill while the Client lives; explicit close awaits +acknowledgement. + +Windows' production Platform backend remains the inherited WINDOWS_HANDOFF.md +integration dependency; generic adapters accept any conforming Backend. Web +browsers have no raw database TCP capability. WASI 0.2 supports TCP/A/AAAA; +SRV/TXT requires native DNS or explicitly resolved seeds.

The rejected +connection must drop its owned stream exactly once and send zero startup bytes. +Pure wire tests cover offer/data combinations, legacy acknowledgement, required +binding errors and authentication bypass. Fourteen real OpenSSL certificates +cover every supported algorithm (including PSS with a different MGF1 hash), plus +Ed25519; independent hashlib digests, every truncated prefix and malformed DER/ +PSS parameters are checked.

Existing query/pool zero gates and TLS's +400 upstream allocations per 100 bidirectional records remain unchanged. + +Initial new-fixture failures were teardown assertions: native reset and WASI p2 +last-operation-failed do not always report EOF.

All SCRAM, +proof, work-count and allocation assertions remain active. No backend/gate was +changed to handle that platform difference. + +### Startup panic and real-server status + +The reported panic is **expected**, not a swallowed real-server failure. +`rejected_startup_reports_server_sqlstate_and_message` catches its synchronous +test-driver panic, asserts SQLSTATE 28000 and the missing-role message, and joins +the scripted peer. Its exact `--nocapture` rerun prints that panic and passes one +test. A comment now explains this behavior. Actual cancellation observers already +use `scram_user`, not an assumed `postgres` role. + +The original `real_async_tls_queries_copy_cancel_pool_and_connection_kill` is +unchanged. A separate ignored `real_async_required_channel_binding_authenticates_over_ssl` +uses auto-derived binding with the required policy and asserts one true `pg_stat_ssl` +row.

No role-level PLUS-only enforcement was +added; the new test proves PLUS through the client's required/verified policy, +while scripted peers inspect the actual mechanism and binding bytes. + +Attempted integrator reproduction: +`python3 scripts/test-servers.py --services postgres,mysql run python3 scripts/ci/run-tests.py protocol --package turnloop-postgres --package turnloop-mysql`. +Fixture command FAIL at PostgreSQL initdb `shmget`, Operation not permitted; +**both SQL suites UNRUN (sandbox)** in this invocation.

ConnectionAborted and isolate no-spin fixtures A terminated backend (57P01 then EOF) reached the async client as a completed query because the core replaced the diagnostic with Transport and async completion accepted Outcome::Aborted. The core now returns Error::ConnectionAborted with the full server error, discards unsent output, rejects reuse and completes each pending token once before Closed; async readers return io::ErrorKind::ConnectionAborted carrying the typed error. Ordinary ERROR still becomes Outcome::ServerError after ReadyForQuery. Error/Outcome are Clone instead of Copy. The parallel no-spin failure was test interference: every owned child subscribes to process-wide SIGCHLD, so unrelated children exiting in parallel tests woke the quiet loop. The unchanged services_no_spin contract now runs in a fresh native_child process (exact success line asserted), and the two SIGUSR1 fan-out fixtures are serialized so one cannot release the other's waiters after SIG_DFL is restored. Verified against real PostgreSQL 16 and MySQL (native and WASI 0.2): the full real_async_tls_queries_copy_cancel_pool_and_connection_kill now runs to the end, including max_uses, pool.end and the cancel-future timeout. --- LANE_REPORT.md | 81 +++++++++ .../turnloop-contract/src/bin/native_child.rs | 13 ++ .../turnloop-contract/tests/native_surface.rs | 25 ++- docs/adb-fix2-commands.md | 81 +++++++++ protocols/turnloop-postgres/Cargo.toml | 4 +- protocols/turnloop-postgres/README.md | 18 ++ .../turnloop-postgres/src/asynchronous.rs | 2 +- protocols/turnloop-postgres/src/client.rs | 12 +- protocols/turnloop-postgres/src/lib.rs | 34 +++- protocols/turnloop-postgres/src/wire.rs | 24 +++ .../turnloop-postgres/tests/allocations.rs | 61 +++++++ .../turnloop-postgres/tests/async_server.rs | 16 +- .../turnloop-postgres/tests/asynchronous.rs | 172 +++++++++++++++++- protocols/turnloop-postgres/tests/protocol.rs | 117 ++++++++++++ 14 files changed, 641 insertions(+), 19 deletions(-) create mode 100644 docs/adb-fix2-commands.md diff --git a/LANE_REPORT.md b/LANE_REPORT.md index 087eed1..077ee6b 100644 --- a/LANE_REPORT.md +++ b/LANE_REPORT.md @@ -252,3 +252,84 @@ run `python3 scripts/test-servers.py --services postgres,mysql run python3 scrip after sourcing `.tools/wasm-env.sh` (UNRUN: sandbox).

The server logs show rs1 stepped down at 00:41:29 with replSetStepDown 5, no election handoff, and rs1 itself winning the next election at 00:41:39 once its 5 s ineligibility had expired, so the same node legitimately became primary again. real_mongodb.rs already uses 60 s; the async test now does too, so a different primary is guaranteed and the assertion is unchanged. --- protocols/turnloop-mongodb/tests/async_server.rs | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/protocols/turnloop-mongodb/tests/async_server.rs b/protocols/turnloop-mongodb/tests/async_server.rs index 1ddf421..27d95d3 100644 --- a/protocols/turnloop-mongodb/tests/async_server.rs +++ b/protocols/turnloop-mongodb/tests/async_server.rs @@ -84,7 +84,7 @@ fn real_async_auth_tls_sdam_pool_cursor_retry_and_primary_stepdown() { let mut cursor=c.cursor(&raw(doc!{"find":"items","filter":{},"batchSize":1,"$db":"async_lane"}),at).await.expect("cursor");let mut rows=0;while let Some(row)=cursor.next(at).await.expect("cursor next"){assert!(row.get_i32("value").expect("value")>=42);rows+=1;}assert_eq!(rows,3);cursor.close(at).await.expect("close cursor"); let before=c.heartbeat_count();h.sleep(Duration::from_millis(1100)).await.expect("heartbeat timer");assert!(c.heartbeat_count()>before);assert_eq!(c.server_count(),3); let mut before_primary=String::new();c.command(&raw(doc!{"hello":1,"$db":"admin"}),&[],OperationKind::RunCommand,at,|r|{before_primary=r.get_str("me").expect("primary me").to_owned();Ok(())}).await.expect("hello"); - let step=c.command(&raw(doc!{"replSetStepDown":5,"force":true,"$db":"admin"}),&[],OperationKind::RunCommand,at,|_|Ok(())).await;if let Err(e) = step { + let step=c.command(&raw(doc!{"replSetStepDown":60,"force":true,"$db":"admin"}),&[],OperationKind::RunCommand,at,|_|Ok(())).await;if let Err(e) = step { let mongo = e.get_ref().and_then(|e| e.downcast_ref::()).expect("MongoDB step-down error"); assert!(matches!(mongo.kind, turnloop_mongodb::ErrorKind::Network) || matches!(mongo.code,Some(91|189|11600|11602)), "unexpected step-down failure: {e}"); }
