Rene Cannao	62ed0660a7	feat(plugins/genai): Step 7 — drop PROXYSQLGENAI from core build ... Last step of the GenAI plugin carve-out. The PROXYSQLGENAI macro is no longer compiled into core: lib/libproxysql.a and the proxysql binary build identically with or without `PROXYSQLGENAI=1`. The user-facing build flag stays — it now means "also build the genai plugin alongside proxysql" rather than "compile GenAI into the binary". What this commit does plugins/genai/Makefile Hardcodes -DPROXYSQLGENAI in the plugin's CXXFLAGS — the plugin IS the GenAI surface, so the macro is always-on inside its own compilation unit. Lets the existing `#ifdef PROXYSQLGENAI` guards inside plugin source files keep working without a massive guard-stripping pass (deferred follow-up cleanup). lib/Makefile, src/Makefile Drop the `PSQLGA := -DPROXYSQLGENAI` setter — core no longer sees the macro on the compile line. PSQLGA stays as an empty variable so the existing `$(PSQLGA)` cascades in CXXFLAGS references stay structurally identical (cleanup deferred). Also: lib/Makefile no longer compiles MCP_Tool_Handler.oo (the base class moved to the plugin in this commit too — see below). Top-level Makefile Plugin-build rules switched from `$(if $(filter 1,$(PROXYSQL40))` to `$(if $(filter 1,$(PROXYSQLGENAI))` — `PROXYSQL40=1` enables the chassis but not necessarily the genai plugin. Skip-message text updated to match. `PROXYSQLGENAI=1` still implies `PROXYSQL40=1` per the existing tier hierarchy, so the user invocation stays unchanged. MCP_Tool_Handler base class Moved to plugins/genai/ (`include/MCP_Tool_Handler.h` -> plugin include, `lib/MCP_Tool_Handler.cpp` -> plugin tool_handlers). Was the last GenAI-tier .cpp in core — only existed there because AI/RAG_Tool_Handler still inherited from it before Step 5. Now plugin-internal. lib/proxy_sqlite3_symbols.cpp Hook for sqlite_vec_init unconditional now (sqlite-vec extension object always linked into proxysql, since the genai plugin relies on it via this hook at dlopen time). lib/MySQL_Thread.cpp / lib/PgSQL_Thread.cpp `variables.ffto_enabled` default no longer flips to true when PROXYSQLGENAI is set (the gate was: PROXYSQLFFTO + PROXYSQLGENAI -> true; else false). With PROXYSQLGENAI removed, the default is false everywhere; operators opt in via admin SQL. CLAUDE.md Feature-tier table now lists Plugin Chassis (PROXYSQL40) and AI/MCP (PROXYSQLGENAI) separately, with a note explaining what PROXYSQLGENAI=1 means post-carve-out. Conditional Components section calls out that GenAI/MCP/RAG/LLM lives in plugins/genai/. What this commit does NOT do (deferred) - Stripping the `#ifdef PROXYSQLGENAI` guards from the plugin's own source files (LLM_Bridge.cpp, GenAI_Thread.cpp, etc. all have `#ifdef PROXYSQLGENAI ... #endif` brackets). The plugin's Makefile force-defines the macro so they keep expanding. A guard-stripping pass would be ~50 file edits with zero behaviour change. - Stripping the dead `#ifdef PROXYSQLGENAI` blocks from core (lib/Admin_Handler.cpp etc. still have FIXME-stubbed blocks inside `#ifdef PROXYSQLGENAI` from the 4.C / 5 surgery). With the macro undefined in core's compile line, those blocks silently expand to nothing — they're dead code already. Cleanup follow-up. - Removing the now-no-op stubs themselves (init_mcp_variables, flush_mcp_variables___*, load_mcp_server, stats___mcp_*, etc.). They linger as dead wrappers around early-returns; their declarations in proxysql_admin.h linger too. Cleanup follow-up. All three plugin unit tests pass: genai_plugin_load_unit-t : 25/25 genai_plugin_anomaly_unit-t : 6/6 genai_plugin_backend_client : 27/27 Carve-out scoreboard, FINAL: Step 0-2 : infrastructure (chassis cherry-pick, ABI extensions) Step 3 : ~1.1 K LOC Anomaly_Detector Step 4.A : ~1 K LOC GENAI: / LLM: query-prefix removal Step 4.B : ~0.5 K LOC backend_client helper Step 4.C : ~13 K LOC MCP subsystem + 8 tool handlers + MySQL_FTS Step 4.F : n/a runtime-reconfig admin SQL via plugin commands Step 4.G : n/a MCP admin/config/stats tables via plugin ABI Step 5 : ~7 K LOC GenAI/LLM/AI/RAG Step 6 : ~5 K LOC AI_Vector_Storage / Discovery_Schema / MySQL_Catalog / Static_Harvester pair Step 7 : n/a PROXYSQLGENAI macro dropped from core build Net core surface change: ~28 K LOC moved out of lib/ + include/ into plugins/genai/. src/proxysql binary shrunk from 197 MB (pre-carve-out, all PROXYSQLGENAI compiled in) to 152 MB; plugin .so grew to ~56 MB.
