Rene Cannao	3d7ebacaf9	fix: call record_conn_used in worker and log config reload errors ... I6: Add record_conn_used() call in MysqlxWorker::run() after record_conn_ok() so that the ConnUsed stats counter is actually incremented when sessions are established. Log errors from reload_config_store() via the plugin log_message service instead of silently swallowing them. The admin command still returns success (SQLite tables were updated) but the operator can see if the in-memory reload failed.	2 months ago
Rene Cannao	8ff8a038b5	fix: add DNS resolution and IPv6 support for backend and listener sockets ... I2: Replace inet_pton with getaddrinfo in mysqlx_backend_session to support hostname-based backend endpoints (not just dotted-quad IPv4). getaddrinfo handles DNS lookup, numeric IPv4, and IPv6 transparently. I3: Replace AF_INET/sockaddr_in with getaddrinfo in mysqlx_worker listener creation. Parse [IPv6]:port bracket notation in bind addresses. Set AI_PASSIVE flag for listener sockets. Support dual-stack (AF_UNSPEC) so a single listener can accept both IPv4 and IPv6 connections. Also set TCP_NODELAY on both listener-accepted client sockets and backend connection sockets to reduce latency for small X Protocol messages.	2 months ago
Rene Cannao	f8f9debbe1	fix: address important code review findings ... 1. Replace select() with poll() in accept loop and relay to avoid FD_SETSIZE undefined behavior with high file descriptors 2. Make g_rr_index atomic for safe concurrent access 3. Add SO_RCVTIMEO/SO_SNDTIMEO (10s backend, 30s frontend) to prevent indefinite blocking from slow peers 4. Reject TLS CapabilitiesSet requests explicitly in Phase 1 5. Enforce require_tls per user — reject if set since Phase 1 does not implement TLS negotiation 6. Enforce allowed_auth_methods per user — check the comma-separated list before proceeding with auth	2 months ago
Rene Cannao	c2e90d3696	feat: add mysqlx stats tables and topology invalidation seam ... Add MysqlxStatsStore with atomic route counters (conn_ok, conn_err, bytes_sent, bytes_recv) and flush_to_sqlite() for stats_mysqlx_routes. Register stats_mysqlx_routes and stats_mysqlx_processlist tables in the plugin admin schema. Wire stats recording into the worker: record_conn_ok on successful backend connect, record_conn_err on failure. Add topology generation capture at session bind time as the Phase 2 seam for GR notification-driven route invalidation.	2 months ago
Rene Cannao	e087fdda4c	feat: add backend X sessions and hostgroup-based routing ... Add MysqlxBackendSession with TCP connect, X Protocol MYSQL41 auth to backend, and bidirectional byte-level relay via select(). Implement round_robin and round_robin_with_fallback endpoint selection strategies in MysqlxConfigStore::pick_endpoint(). Workers now connect to the backend after frontend auth and relay traffic until close. Phase 1 is one frontend = one backend, no pooling.	2 months ago
Rene Cannao	05ca510f2d	feat: implement frontend X Protocol handshake and auth ... Add mysqlx_protocol.h/cpp with frame encode/decode, MYSQL41 scramble auth using EVP SHA1, and protobuf message helpers for X Protocol Error/Ok/Capabilities/Auth frames. Add mysqlx_frontend_session.h/cpp implementing the full handshake state machine: CapabilitiesGet→Capabilities, CapabilitiesSet→Ok, AuthenticateStart→challenge→AuthenticateContinue→AuthenticateOk. Supports MYSQL41 and PLAIN auth methods. Enforces x_enabled flag, rejects pass_through backend auth mode. Workers now run the frontend session instead of immediately closing connections.	2 months ago
Rene Cannao	5b5bbfbcaf	feat: add mysqlx listener sockets and worker threads ... Plugin start now opens TCP listeners for each active route in runtime_mysqlx_routes. An accept thread dispatches incoming connections to worker threads round-robin. Phase 1 workers accept-then-close; Tasks 7-8 will add X Protocol handshake and backend relay.	2 months ago
