Rene Cannao	a9f2eaaa13	feat: remove PROXYSQLGENAI flag, genai now builds under PROXYSQL40 (issue #5722) ... PROXYSQLGENAI flag eliminated entirely. PROXYSQL40=1 now unconditionally builds the genai plugin alongside core. All #ifdef PROXYSQLGENAI replaced with #ifdef PROXYSQL40 in source, Makefiles, and 61 CI workflows.	2 months ago
Rene Cannao	5fe286e972	feat(plugins/genai): Step 4.C — move MCP subsystem into the plugin ... Per docs/superpowers/plans/2026-04-19-step4-mcp-subsystem-move.md "4.C / 4.D / 4.E merge" revision. This is the largest single carve-out commit so far: ~13 K LOC physically relocated, plus surgical edits across the core admin SQL surface to neutralize references to the moved code. What moved (git mv preserves history) Tool handlers (lib/<name>.cpp -> plugins/genai/src/tool_handlers/<name>.cpp; include/<name>.h -> plugins/genai/include/<name>.h) Admin_Tool_Handler, Cache_Tool_Handler, Config_Tool_Handler, MySQL_Tool_Handler, Observe_Tool_Handler, Query_Tool_Handler, Stats_Tool_Handler. MCP listener stack (lib/<name>.cpp -> plugins/genai/src/<name>.cpp; include/<name>.h(pp) -> plugins/genai/include/...) MCP_Endpoint, MCP_Thread, ProxySQL_MCP_Server. Promoted from Step 6 (bidirectional dep with MySQL_Tool_Handler): MySQL_FTS. MCP_Tool_Handler base stays in core because AI_Tool_Handler and RAG_Tool_Handler (Steps 5/6 scope) inherit from it; moving the base would force pulling those in too. Plugin lifecycle takeover plugins/genai/include/genai_plugin.h: GenAIPluginContext now holds the MCP_Threads_Handler*. plugins/genai/src/plugin_main.cpp: genai_init constructs the MCP_Threads_Handler and assigns to a plugin-local GloMCPH symbol (the legacy global name, kept for the moved tool handlers that still reference it; the symbol no longer exists in core). genai_stop tears down on shutdown. genai_start is a no-op for now; the MCP listener auto-start is gated on the admin-SQL surface that 4.F restores. plugins/genai/src/ProxySQL_MCP_Server.cpp: AI_Tool_Handler and RAG_Tool_Handler endpoint registration is disabled via stub assignments (the headers stay included so member-pointer types resolve). Steps 5/6 re-enable when those classes move into the plugin. Core neutralization (FIXME stubs awaiting 4.F/4.G) src/main.cpp: GloMCPH global removed; ProxySQL_Main_init_MCP_module removed; shutdown block deleted. lib/ProxySQL_Admin.cpp: init_mcp_variables, load_mcp_server, load_mcp_query_rules_to_runtime, save_mcp_query_rules_from_runtime stubbed to no-ops; original bodies preserved inside `#if 0` for 4.F reference. lib/Admin_FlushVariables.cpp: flush_mcp_variables___database_to_runtime and flush_mcp_variables___runtime_to_database stubbed similarly. lib/ProxySQL_Admin_Stats.cpp: stats___mcp_query_tools_counters, stats___mcp_query_digest, stats___mcp_query_rules stubbed. lib/Admin_Handler.cpp: has_variable("mcp-…") and the load_target_auth_map call site in LOAD MCP PROFILES … stubbed. Result: the MCP listener does NOT start automatically between this commit and 4.F (mcp-* admin variables are not pushed into the running plugin). Documented in the plan's "4.C/4.D/4.E merge" section. src link change: --whole-archive on libproxysql.a src/Makefile: the proxysql binary now links libproxysql.a with -Wl,--whole-archive so all symbols are exported via -Wl,--export-dynamic, allowing the genai plugin .so to dlopen cleanly even when core code paths don't reference moved-but-still- in-core classes (LLM_Bridge, Discovery_Schema, MySQL_Catalog, Static_Harvester, …) directly. test/tap/tests/unit/Makefile gets the same change so unit tests can dlopen the plugin. Without this, ld dead-code-eliminates the unreferenced symbols and dlopen fails with "undefined symbol". Tests passing - genai_plugin_anomaly_unit-t : 6/6 - genai_plugin_load_unit-t : 8/8 (lifecycle init/start/stop + admin table registration) - genai_plugin_backend_client_unit-t : 27/27 Carve-out scoreboard Step 0-2 : 0 (infrastructure only) Step 3 : ~1.1 K (Anomaly_Detector) Step 4.B : ~0.5 K (backend_client helper, no callers yet) Step 4.C : ~13 K (this commit; MCP subsystem) Pending : Steps 4.F, 4.G, 5, 6, 7	2 months ago
