Rene Cannao	28cf4ceab8	feat(plugins/genai): Step 5 — move GenAI/LLM/AI surface into the plugin ... Largest carve-out commit since 4.C: moves the GenAI / LLM / AI / RAG surface (about 7K LOC) out of core into plugins/genai/. After this commit, libproxysql.a no longer publishes any of GenAI_Threads_Handler, LLM_Bridge, LLM_Clients, AI_Features_Manager, AI_Tool_Handler, RAG_Tool_Handler, or the legacy GloGATH/GloAI globals. Files moved (git mv preserves history) Headers (include/ -> plugins/genai/include/) GenAI_Thread.h LLM_Bridge.h AI_Features_Manager.h AI_Tool_Handler.h RAG_Tool_Handler.h (promoted from Step 6 — bidirectional dep with AI_Features_Manager forced the early move, same way MySQL_FTS.h got promoted in 4.C) Sources (lib/ -> plugins/genai/src/ or …/tool_handlers/) GenAI_Thread.cpp LLM_Bridge.cpp LLM_Clients.cpp (.cpp without a header; class decls live in LLM_Bridge.h) AI_Features_Manager.cpp AI_Tool_Handler.cpp -> tool_handlers/ RAG_Tool_Handler.cpp -> tool_handlers/ Plugin lifecycle takeover plugins/genai/src/plugin_main.cpp: - Defines plugin-local GloGATH and GloAI alongside the existing GloMCPH (all three are .so-internal aliases for the contexts genai_init constructs). - genai_init now also constructs GenAI_Threads_Handler (calls ->init()) and AI_Features_Manager (calls ->init()), mirroring the pre-Step-5 ProxySQL_Main_init_GenAI_module sequence. - genai_stop tears them down in reverse order. plugins/genai/src/ProxySQL_MCP_Server.cpp: - AI / RAG endpoint registration re-enabled (was #if 0'd in 4.C because the constructors weren't reachable from the plugin then). /mcp/ai and /mcp/rag are once again live when the operator has GloAI configured. plugins/genai/src/Anomaly_Detector.cpp + plugin_main.cpp: - get_query_embedding() now calls through a function-pointer hook (genai_anomaly_embed_fn) that plugin_main installs in genai_init and clears in genai_stop. This indirection lets the test fixture (which compiles Anomaly_Detector.cpp directly into a test binary, without GenAI_Thread.cpp) link cleanly — the pointer stays null, the detector short-circuits to empty embedding, and the existing nullptr-guard in check_embedding_similarity does the rest. Core neutralization src/main.cpp: - Drops the GloGATH / GloAI globals, ProxySQL_Main_init_GenAI_module definition + call, the shutdown branch, and the `if (GloGATH) init_genai_variables()` call. lib/Admin_Bootstrap.cpp / Admin_FlushVariables.cpp / Admin_Handler.cpp / ProxySQL_Admin.cpp / MySQL_Session.cpp / ProxySQL_Admin_Stats.cpp: - Drop the corresponding `#include` and `extern` declarations. - flush_genai_variables___* stubbed (mirrors the 4.C MCP pattern; original bodies preserved in `#if 0` for the upcoming LOAD/SAVE GENAI verbs port). lib/Admin_Handler.cpp: - Loose-prefix accept for `genai-*` in is_valid_global_variable (mirrors the 4.F mcp-* fix), so SET genai-X=Y still reaches main.global_variables; runtime push happens via the plugin's LOAD GENAI VARIABLES TO RUNTIME (registered in a follow-up). include/cpp.h, include/proxysql.h: - Removed the AI_Features_Manager.h / LLM_Bridge.h / GenAI_Thread.h / AI_Tool_Handler.h / RAG_Tool_Handler.h includes that no longer resolve from core's -I path. test/tap/test_helpers/test_globals.cpp: - Drops the matching `#include`s and stub globals. Test fixture test/tap/tests/unit/Makefile: - PROXYSQLGENAI auto-detect probe switched from `GenAI_Thread` (now plugin-only) to `AI_Vector_Storage` (still in core for Step 6). After Step 6 the probe will switch again, and Step 7 deletes the auto-detect entirely. 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: Step 0-2 : infrastructure Step 3 : ~1.1 K LOC (Anomaly_Detector) Step 4.B : ~0.5 K LOC (backend_client) Step 4.C : ~13 K LOC (MCP subsystem) Step 4.F : runtime-reconfig admin SQL routed through plugin commands Step 4.G : MCP admin / config / stats tables registered via plugin ABI Step 5 : ~7 K LOC (GenAI/LLM/AI/RAG) Pending: Step 6 (AI_Vector_Storage, MySQL_Catalog, Discovery_Schema, Static_Harvester, PgSQL_Static_Harvester) and Step 7 (delete the PROXYSQLGENAI macro entirely).	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
Rahim Kanji	4b2334e493	test: enable SQLite URI parsing in unit-test harness ... Calls sqlite3_config(SQLITE_CONFIG_URI, 1) at the top of test_globals_init(), mirroring src/main.cpp. Without this, SQLite3DB::open("file:mem_mydb?mode=memory", ...) used by both HostGroups Manager constructors falls back to literal-filename behavior in unit tests and creates a stray on-disk file in the test cwd instead of an in-memory database. The daemon already sets this flag before any component is constructed; the test harness now does the same.	3 months ago
René Cannaò	b187f9ac96	Address review feedback on test harness (PR #5482) ... Fixes from Copilot and Greptile review comments: - test_globals.cpp: Replace fixed-size datadir_buf[256] with std::string to avoid truncation on long TMPDIR paths - test_globals.cpp: Initialize glovars.has_debug to match build type (DEBUG vs release) so component constructors that validate debug compatibility do not abort - test/tap/Makefile: Remove 'tap' dependency from unit_tests target since unit tests compile tap.o directly and don't need the full libtap.so/cpp-dotenv build chain. Also remove $(MAKECMDGOALS) pass- through which would cause failures when invoked as 'make unit_tests' - tests/unit/Makefile: Fix default goal — make 'all' the first target so 'make' without arguments builds unit tests correctly	3 months ago
René Cannaò	803eb27590	Add unit test harness: Glo* stubs and component init helpers ... Introduces the test infrastructure foundation for Phase 2.1 (#5473) of the unit testing framework (#5472). This enables unit test binaries to link against libproxysql.a without main.cpp, allowing individual components to be tested in isolation. New files: - test/tap/test_helpers/test_globals.h/.cpp: Stub definitions for all 25 Glo* global pointers and the PROXYSQL_EXTERN-based variable definitions (GloVars, MyHGM, PgHGM, __thread vars, tracked vars). Also stubs symbols from src/ (proxy_tls, SQLite3_Server, binary_sha1) and TAP noise testing functions. - test/tap/test_helpers/test_init.h/.cpp: Component initialization helpers (test_init_minimal, test_init_auth, test_init_query_cache, test_init_query_processor) with matching cleanup functions. All are idempotent and safe to call multiple times.	3 months ago
