Rene Cannao 482ce386cd chore(genai-carveout): strip dead PROXYSQLGENAI blocks + plugin hardening ... Two threads of cleanup that had to land together because they touch both core (where the dead code lives) and the plugin (where the new module-owned state lives): # Strip dead #ifdef PROXYSQLGENAI from lib/, include/, src/ (Spec Q9) Step 7 of the carve-out left PSQLGA empty in lib/Makefile, so every #ifdef PROXYSQLGENAI block in the core build became permanently false. The blocks remained as dead text (visible to readers, irrelevant to the binary). Strip ~600 lines spanning: src/main.cpp 2 sites lib/Admin_Bootstrap.cpp 3 sites (mcpdb open + attach + flush_*_variables hooks) lib/Admin_FlushVariables.cpp 2 sites (~250 lines of stub + #if 0 _ORIGINAL bodies) lib/Admin_Handler.cpp 5 sites (LOAD/SAVE GENAI VARIABLES dispatch + LOAD/SAVE MCP VARIABLES dispatch + MCP profiles handler) lib/ProxySQL_Admin.cpp ~10 sites (init_*_variables + load_mcp_server + load/save_mcp_query_rules + GenericRefreshStatistics MCP probes) lib/ProxySQL_Admin_Stats.cpp 3 stats___mcp_* function bodies include/proxysql_admin.h 7 method declarations include/ProxySQL_Admin_Tables_Definitions.h 4 unused DDL macros The plugin now owns LOAD/SAVE MCP VARIABLES, LOAD/SAVE GENAI VARIABLES, LOAD/SAVE MCP PROFILES, LOAD/SAVE MCP QUERY RULES via its admin command registry; the chassis dispatcher catches them before any of the dead core branches would have fired. Caveat — known break: the `stats_mcp_*` tables are still registered (empty schema) but the populator path that fed them is gone. SELECTs return empty result sets until a follow-up wires the populator into the plugin (likely via register_runtime_view or a parallel stats-side ABI). Tracked separately. # Plugin hardening (review-feedback items 4-7) * plugins/genai/Makefile: add -fvisibility=hidden, -fvisibility-inlines-hidden, -fstack-protector-strong (mirrors plugins/mysqlx). Tag proxysql_plugin_descriptor_v1 with __attribute__((visibility("default"))) so the loader's dlsym still resolves; without the explicit annotation the hidden-default flag would also hide the entry point. * plugins/genai/src/Anomaly_Detector.cpp: convert genai_anomaly_embed_fn to std::atomic<…> with relaxed loads/stores. The detector hot-path read races with init/stop on the lifecycle thread; atomics give us a portable no-torn-pointer guarantee without paying for acquire/release fences we don't need (no other state synchronises with the pointer). Replaces the hand-wavy "no mutex needed" comment with the actual reasoning. * plugins/genai/src/{plugin_main,plugin_commands,plugin_tables}.cpp: route the 17 fprintf(stderr, "genai plugin: ...") log lines through a new genai_log() helper that calls services->log_message when the chassis is wired up and falls back to stderr for early-init / unit-test paths. Lines now land in proxysql.log alongside the rest of the runtime. * plugins/genai/include/MCP_Thread.h: add get_variable_string(name, std::string&) returning a std::string, and switch mcp_save_variables_to_admindb (plugin_main.cpp) to it. The legacy get_variable(name, char*) had an unbounded sprintf into a stack buffer and the SAVE path was passing char val[256] — a real overflow risk for *_endpoint_auth bearer tokens. * plugins/genai/src/plugin_main.cpp: rewrite the genai_init / genai_stop comment block with the actual teardown ordering rationale (consumers before producers; atomic-clear-then-delete for the embed hook; why Prometheus counters stay registered).		2 months ago
