Rene Cannao	b6b6a4f62b	fix(genai): properly gate sqlite-vec hook on PROXYSQLGENAI ... Reverts d7a5eb463 (which incorrectly made sqlite-vec build unconditional, bloating v3.0 release binaries with vector-search code that no plain MySQL/PgSQL proxy install needs) and instead applies the proper architectural fix: re-gate the hook in core on PROXYSQLGENAI so vec.o is only built and only linked into the proxysql binary when the build is intended to host the genai plugin. Step 7 of the carve-out had emptied PSQLGA in lib/Makefile under the premise that "core no longer guards anything with PROXYSQLGENAI", but two call sites in core remained: - lib/proxy_sqlite3_symbols.cpp:53-59 — declares the proxy_sqlite3_vec_init function pointer (the genai plugin's AI_Vector_Storage calls back through this hook when loaded). - lib/Admin_Bootstrap.cpp:618 — registers the auto-extension so new admin DB connections see the vec_* SQL functions. Both reference symbols (sqlite3_vec_init / sqlite-vec.h) that deps/Makefile only builds when PROXYSQLGENAI=1. The mismatch manifested as a CI failure on debian12-dbg / ubuntu22-tap: proxy_sqlite3_symbols.cpp:58:10: fatal error: sqlite-vec.h: No such file or directory # Changes * lib/proxy_sqlite3_symbols.cpp: wrap the sqlite-vec include + proxy_sqlite3_vec_init definition in `#ifdef PROXYSQLGENAI`. * lib/Admin_Bootstrap.cpp: same gate on the extern declaration and the proxy_sqlite3_auto_extension registration call. * src/Makefile: only append SQLITE_VEC_OBJ to LIBPROXYSQLAR when PROXYSQLGENAI=1. v3.0 release binaries skip vec.o entirely. * lib/Makefile: re-set PSQLGA = -DPROXYSQLGENAI when PROXYSQLGENAI=1. Step 7 left it empty thinking core had no references; the two sites above prove that was incorrect. * deps/Makefile: revert d7a5eb463. sqlite-vec stays gated on PROXYSQLGENAI as it always was. # Why this is better than the previous attempt The d7a5eb463 fix made deps unconditionally build vec.o which would have shipped a ~1MB vector-search extension to every v3.0 release package. Re-gating in core preserves the carve-out invariant: GenAI weight (including its SQLite extension) ships ONLY in builds that explicitly opted into PROXYSQLGENAI=1, and v3.0 dbg / release binaries built without the flag stay lean.	2 months ago
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.

Rene Cannao	4552236700	feat(plugins/genai): Step 6 — move RAG/Vector/discovery surface into the plugin ... Final file-move step in the carve-out: relocates the leaf modules that didn't depend on (and weren't depended on by) anything still in core. After this commit, the only PROXYSQLGENAI-guarded code remaining in libproxysql.a is `MCP_Tool_Handler` — the base class the plugin's AI_Tool_Handler / RAG_Tool_Handler inherit from — and that lives in core only because removing it would force pulling those derived plugin classes into core just for the inheritance edge. Step 7 deletes the PROXYSQLGENAI macro entirely. Files moved (git mv preserves history) Headers (include/ -> plugins/genai/include/) AI_Vector_Storage.h MySQL_Catalog.h Discovery_Schema.h Static_Harvester.h PgSQL_Static_Harvester.h Sources (lib/ -> plugins/genai/src/) AI_Vector_Storage.cpp MySQL_Catalog.cpp Discovery_Schema.cpp Static_Harvester.cpp PgSQL_Static_Harvester.cpp Core changes were minimal because these are leaf modules: include/proxysql.h: drop the AI_Vector_Storage.h include. include/cpp.h: drop AI_Vector_Storage / Discovery_Schema / MySQL_Catalog / Static_Harvester / PgSQL_Static_Harvester includes (replaced with a single carve-out history comment that Step 7 will delete entirely). lib/ProxySQL_Admin.cpp: drop the Discovery_Schema.h include — its only live use was via the now-#if-0'd save/load_mcp_query_rules blocks 4.C left behind for follow-up reference. lib/Makefile: drop AI_Vector_Storage.oo, MySQL_Catalog.oo, Discovery_Schema.oo, Static_Harvester.oo, PgSQL_Static_Harvester.oo from the GenAI _OBJ_CXX list. Test fixture probe update test/tap/tests/unit/Makefile: PROXYSQLGENAI auto-detect probe switched from `AI_Vector_Storage` (now plugin-only) to `MCP_Tool_Handler` (the last GenAI-tier symbol still in core). 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 Binary size deltas: src/proxysql 159 MB -> 152 MB (-7 MB) plugins/genai/...Plugin.so 47 MB -> 55 MB (+8 MB) Net process RSS roughly neutral, as the design predicted. 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 + tool handlers + MySQL_FTS) 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) Step 6 : ~5 K LOC (AI_Vector_Storage + Discovery_Schema + MySQL_Catalog + Static_Harvester pair) Pending: Step 7 — delete the PROXYSQLGENAI macro from build flags and any remaining `#ifdef PROXYSQLGENAI` blocks.	2 months ago
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
Rene Cannao	f1c0ea2dbc	feat(genai): Step 3 — carve Anomaly_Detector out of core into plugins/genai/ ... Per docs/superpowers/specs/2026-04-16-genai-plugin-carveout-design.md "Migration sequence — Step 3", this is the first step that actually moves GenAI surface out of libproxysql.a. The Anomaly_Detector now lives entirely inside the genai plugin and is exercised through the plugin query-hook ABI added in Step 2; core has zero references to it. Files moved (git mv preserves history): include/Anomaly_Detector.h -> plugins/genai/include/Anomaly_Detector.h lib/Anomaly_Detector.cpp -> plugins/genai/src/Anomaly_Detector.cpp Plugin-side adjustments: - Drop the `#ifdef PROXYSQLGENAI` guard from both files (the file only compiles inside the plugin now; the macro remains a core build flag but the carve-out gates these files by *location*, not by macro). - Update the json-include relative path to the new depth. - Replace `Anomaly_Detector::get_query_embedding` with a stub that returns an empty vector. The previous implementation called `GloGATH->embed_documents`, but `GloGATH` (the GenAI_Threads_Handler) is still a core symbol at this point in the carve-out. The embedding-similarity stage was already nullptr-guarded on `vector_db`, so an empty embedding short-circuits cleanly to "no anomaly". Step 5 reattaches the embedding back-end when GenAI_Thread moves into the plugin. Plugin lifecycle wiring (plugins/genai/src/plugin_main.cpp): - `genai_init` now: registers two Prometheus counters (`proxysql_genai_detected_anomalies_total`, `proxysql_genai_blocked_queries_total`) against the shared registry exposed by Step 2.3, registers the query hook for both MySQL and PgSQL protocols, and constructs the Anomaly_Detector. - `genai_start`: flips the started flag (the detector has no separate start phase). - `genai_stop`: closes and deletes the detector; counters stay registered (prometheus-cpp has no Unregister). Plugin query-hook adapter (plugins/genai/src/plugin_hooks.cpp, NEW): - Bridges ProxySQL_PluginQueryHookPayload to Anomaly_Detector::analyze. - Increments the appropriate Prometheus counter on detection / block. - Translates AnomalyResult into ALLOW or DENY(message) per the ABI. Core removals (the symmetric carve-out): - lib/MySQL_Session.cpp: delete the in-core `#ifdef PROXYSQLGENAI` anomaly-detection block in COM_QUERY (lines around 5370-5377 pre-edit) and the `handler___status_WAITING_CLIENT_DATA___STATE_SLEEP___MYSQL_COM_QUERY_detect_ai_anomaly` method. Same logic now runs inside the plugin via the query hook added in Step 2.2. - include/MySQL_Session.h: drop the matching method declaration. - lib/AI_Features_Manager.{cpp,h}: remove the anomaly_detector field, init_anomaly_detector(), close_anomaly_detector(), get_anomaly_detector(), and the corresponding init() / shutdown() call sites. AI_Features_Manager now owns only the LLM bridge and vector_db (LLM_Bridge moves in Step 5; vector_db in Step 6). - lib/AI_Tool_Handler.{cpp,h}: drop the anomaly_detector field and the constructor parameter that fed it -- the field was stored but never read, dead code that was awkward to keep alive across the carve-out. - lib/ProxySQL_MCP_Server.cpp: update the AI_Tool_Handler ctor call site accordingly (one less argument). - include/MySQL_Thread.h: remove `st_var_ai_detected_anomalies` / `st_var_ai_blocked_queries` from `enum status_variable_id` and `ai_detected_anomalies` / `ai_blocked_queries` from `enum p_th_counter`. The plugin's Prometheus counters replace these (the old ones were per-thread integer increments surfaced by the legacy stats path; the plugin uses Prometheus directly). - lib/MySQL_Thread.cpp: drop the matching entries from MySQL_Thread_status_variables_counter_array and from th_metrics_map (the prometheus registration table). - include/proxysql.h, include/cpp.h: drop the now-stale `#include "Anomaly_Detector.h"` lines. - lib/Makefile: drop Anomaly_Detector.oo from the libproxysql object list. Tests: - Delete the in-core TAP tests that linked against the removed symbols: anomaly_detection-t, anomaly_detection_integration-t, anomaly_detector_unit-t (Docker-dependent, won't link), plus the unit test genai_anomaly_unit-t (linked against libproxysql's copy). - Add test/tap/tests/unit/genai_plugin_anomaly_unit-t.cpp: replaces the deleted unit test by compiling the plugin's Anomaly_Detector.cpp directly into the test binary. The friend-class helper pattern (Anomaly_Detector_TestHelper) is preserved so private methods (normalize_query, check_sql_injection) remain testable. Six assertions cover the same surface plus a regression test that analyze() now runs cleanly without a vector_db. Plugin Makefile changes: - Add Anomaly_Detector.cpp + plugin_hooks.cpp to SRCS. - Pull in the include paths Anomaly_Detector.cpp's transitively- included headers need (mariadb client for mysql.h, libev, libscram, libusual, postgresql, jemalloc, microhttpd, libhttpserver, curl, re2, pcre, zstd, libconfig, libdaemon, ssl). These mirror the set already used by test/tap/tests/unit -- the test harness pulls the same headers in transitively from libproxysql.a's headers. Doxygen documentation added for every new function and for the new header structures (GenAIPluginContext fields, genai_query_hook, register_prometheus_counters, all three lifecycle callbacks, plus file-level @brief blocks for plugin_main.cpp, plugin_hooks.cpp, genai_plugin.h, and the moved Anomaly_Detector.{h,cpp}). Verified end-to-end: - Full clean rebuild of libproxysql.a + proxysql + ProxySQL_GenAI_Plugin.so. - All 60 unit-test binaries pass (genai_anomaly_unit-t replaced by genai_plugin_anomaly_unit-t; net same). - Smoke test: launching proxysql with plugins=("...ProxySQL_GenAI_Plugin.so") shows "Anomaly: Initializing Anomaly Detector v0.1.0" / "Anomaly Detector initialized with 11 injection patterns" in the log on startup, and "Anomaly Detector closed" on SIGTERM -- the plugin's lifecycle owns the detector cleanly. Carve-out scoreboard so far (lines of GenAI surface moved out of core): Step 0-2 : 0 (infrastructure prep only) Step 3 : ~1100 (Anomaly_Detector.{h,cpp}) + counter/handler removals	2 months ago
Rene Cannao	b3d4de0bc8	Merge remote-tracking branch 'origin/v3.0' into plugin-chassis ... # Conflicts: # test/tap/groups/groups.json	2 months ago
Rene Cannao	cd48c5613e	feat(plugin-chassis): gate chassis ABI additions behind PROXYSQL40 ... The four-phase plugin lifecycle (Step 2.2), pre-execution query-hook ABI (Step 2.1), shared Prometheus registry access (Step 2.3), and generic admin-command alias dispatch (Step 2.5) introduce new plugin ABI surface area — a new descriptor field (register_schemas), new services-struct entries (register_query_hook, get_prometheus_registry, register_command_alias), new public manager methods (invoke_register_schemas_phase, dispatch_query_hook, etc.), and a new startup ordering in main(). These changes should not appear in the v3.x stable/innovative tiers. Wrap every chassis-only declaration, definition, and dispatch path in `#ifdef PROXYSQL40` so the v3.0/v3.1 builds retain the pre-chassis behavior: a single init()-only descriptor layout, two-phase load+init lifecycle, and the hardcoded MYSQLX alias ladder in Admin_Handler.cpp. Changes: * Top-level Makefile: introduce PROXYSQL40 as a distinct tier above PROXYSQL31. Cascade rule: PROXYSQLGENAI=1 implies PROXYSQL40=1 implies PROXYSQL31=1. Bump major version number on PROXYSQL40=1 (previously tied to PROXYSQLGENAI). Export PROXYSQL40 for recursive submakes. * lib/Makefile, src/Makefile: add -DPROXYSQL40 via $(PSQL40) so the compile commands match the top-level tier selection. * include/ProxySQL_Plugin.h: gate the register_schemas descriptor field, query-hook types/enums/typedefs, the alias-registration callback, and the trailing services-struct fields (register_query_hook, get_prometheus_registry, register_command_alias). The pre-chassis descriptor remains six fields (name, abi_version, init, start, stop, status_json) so plugins built against v3.x headers still link and load. * include/ProxySQL_PluginManager.h: gate the chassis-exclusive public methods and private members (schemas_registered, aliases, services_phase_b_, query hook pointers). Provide two declarations of proxysql_load_configured_plugins — the four-phase variant (paired with proxysql_init_configured_plugins) under PROXYSQL40, the legacy single-call variant otherwise. * lib/ProxySQL_PluginManager.cpp: gate every method that belongs to the chassis (invoke_register_schemas_phase, register_command_alias, resolve_alias_to_canonical, register_query_hook, has_query_hook, dispatch_query_hook), plus the services_phase_b_ initialization (nullptr DB handle stubs), the proxysql_dispatch_configured_plugin_ query_hook entry point, and the alternate four-phase body of proxysql_load_configured_plugins / proxysql_init_configured_plugins. The legacy two-phase loader is restored under !PROXYSQL40. get_admindb_service / get_configdb_service / get_statsdb_service stay ungated because they back the unconditional services_ member. * lib/Admin_Handler.cpp: gate the `#include \"ProxySQL_PluginManager.h\"` and restore under !PROXYSQL40 the 16 hardcoded MYSQLX alias vectors plus the 16-deep if-ladder in admin_handler_command_*(). Under PROXYSQL40 the ladder is replaced by a single call to proxysql_resolve_configured_plugin_admin_alias(), which is plugin-agnostic. * src/main.cpp: gate InitConfiguredPlugins and branch the startup sequence in ProxySQL_Main_init_phase2___not_started: - PROXYSQL40: LoadConfiguredPlugins (Phase A+B) -> admin init (C) -> materialize_plugin_tables -> InitConfiguredPlugins (D) -> StartConfiguredPlugins (E). - !PROXYSQL40: admin init -> LoadConfiguredPlugins (combined load+init) -> materialize_plugin_tables -> StartConfiguredPlugins, matching the pre-chassis ordering. * plugins/mysqlx/src/mysqlx_plugin.cpp: split init under PROXYSQL40 into mysqlx_register_schemas (schema + commands) and a minimal mysqlx_init (context only). Under !PROXYSQL40 the original single mysqlx_init remains. Descriptor conditionally wires register_schemas. * plugins/mysqlx/src/mysqlx_admin_schema.cpp: under PROXYSQL40 use the reg() helper to register canonical+aliases via the new ABI; under !PROXYSQL40 fall back to 16 direct register_command() calls (aliases handled by Admin_Handler's hardcoded ladder). * test/tap/test_helpers/fake_plugin.cpp: gate fake_query_hook, fake_register_schemas, fake_descriptor_with_phase_b, the REGISTER_QUERY_HOOK block in fake_init, and the ENABLE_PHASE_B descriptor selection. The pre-chassis descriptor-returning stub is the sole return path under !PROXYSQL40. * test/tap/tests/unit/Makefile: autodetect PROXYSQL40 via invoke_register_schemas_phase (the chassis-exclusive symbol) in the library archive; add -DPROXYSQL40 to fake_plugin .so compilation so the descriptor layout matches the loader's expectations; append the three chassis-only tests (plugin_lifecycle, plugin_prometheus, plugin_query_hook) to UNIT_TESTS only when PROXYSQL40=1. * test/tap/tests/unit/plugin_config_unit-t.cpp, test/tap/tests/unit/plugin_dispatch_unit-t.cpp: compile-time-gate the chassis-only subtests, adjust plan() counts per mode (48/50 with PROXYSQL40, 47/32 without), and provide a proxysql_init_configured_plugins_compat() helper that is a no-op returning true under !PROXYSQL40 so shared test helpers work in both modes. Verification — all plugin unit tests pass in both modes: PROXYSQL40=1 build (chassis enabled): plugin_config_unit-t: 48/48 plugin_dispatch_unit-t: 50/50 plugin_lifecycle_unit-t: 14/14 plugin_query_hook_unit-t: 41/41 PROXYSQL40=0 build (v3.x behavior): plugin_config_unit-t: 47/47 plugin_dispatch_unit-t: 32/32 (plugin_lifecycle, plugin_query_hook not built)	2 months ago

Selection algorithm: 1. Filter candidates by eligibility (ONLINE, below max_connections, within latency/lag thresholds) 2. Weighted random selection using seeded LCG (deterministic for testing, avoids polluting global srand() state) Uses its own ServerSelectionStatus enum to avoid pulling in proxysql_structs.h and its entire dependency chain.	3 months ago

Rene Cannao	c2f678a9de	feat: implement release tiers and feature guards for v3.0, v3.1, and v4.0 ... This commit introduces a structured release tier system controlled by environment variables, allowing three distinct ProxySQL versions to be built from the same codebase while maintaining a clear upgrade path. Key Changes: - Tier 1 (v3.0.x Stable): Default build including bug fixes and core enhancements. - Tier 2 (v3.1.x Innovative): Enabled via PROXYSQL31=1. Adds FFTO and TSDB. - Tier 3 (v4.0.x AI/MCP): Enabled via PROXYSQLGENAI=1. Adds the AI stack. Implementation Details: - Makefile: Implemented dynamic versioning logic that increments the minor version for v3.1 and the major version for v4.0. Added tier documentation. - Feature Guards: Introduced PROXYSQLFFTO and PROXYSQLTSDB guards across ProxySQL_Admin, ProxySQL_Statistics, REST API, and HTTP server. - FFTO: Guarded Fast Forward Traffic Observer in MySQL and PgSQL sessions, including thread-local variables and configuration parameters. - TSDB: Guarded the entire Time Series Database subsystem, including SQLite table definitions, background loops, and REST API endpoints. - Build Fixes: * Fixed 'proxy_debug_func' linkage by adding extern "C" and moving the definition outside of DEBUG guards to ensure non-debug builds link correctly. * Corrected misplaced/nested DEBUG and PROXYSQLFFTO guards. * Verified build stability for all tiers (unset, PROXYSQL31=1, PROXYSQLGENAI=1).	4 months ago

Rene Cannao	20d6282a60	build(clean): ignore and remove generated MySQL parser artifacts ... Context: - Bison/Flex-generated parser files in `lib/` can be created locally during parser work. - These files are generated artifacts and should not be tracked. Changes: - Add generated parser artifacts to `.gitignore`: - `lib/MySQL_Lexer.yy.c` - `lib/MySQL_Parser.output` - `lib/MySQL_Parser.tab.c` - `lib/MySQL_Parser.tab.h` - Extend `lib/Makefile` `clean` target to remove the same generated files. Why: - Prevent accidental inclusion of regenerated parser outputs in feature commits. - Keep worktrees clean and make `make clean` deterministic for parser-related changes.	4 months ago

Rene Cannao	9685cdaa4b	mcp discovery: enforce target-scoped run model and add protocol-aware static harvesting (mysql+pgsql) ... Refactor the MCP query/discovery stack to remove prototype-era MySQL-only assumptions and make discovery/catalog semantics explicitly target-scoped. This commit is intentionally not backward compatible with legacy single-target catalog metadata. Key implementation details: - Discovery_Schema: - runs table now stores target_id, protocol, and server_version - resolve_run_id() now requires target_id and resolves schemas within target scope - create_run() now records target/protocol/server version - added legacy schema detection + destructive catalog table rebuild when old runs layout is found - fixed resultset lifetime/escaping issues in target-aware run resolution - New PostgreSQL static harvester: - added PgSQL_Static_Harvester class and build wiring - harvests schemas/objects/columns/indexes/fks/view definitions into Discovery_Schema - maps pg metadata to object_id-based insert APIs used by Discovery_Schema - Query_Tool_Handler: - constructor simplified to catalog_path only (no mcp-mysql_* runtime ctor deps) - discovery.run_static now requires target_id and dispatches protocol-aware harvester at runtime - catalog.*, agent.run_start, and llm.* tool contracts now require target_id when resolving run_id - all run_id resolution call sites switched to resolve_run_id(target_id, ...) - list_schemas catalog query now scoped by target_id via runs join - digest logging path now resolves run_id in target context - ProxySQL_MCP_Server: - updated Query_Tool_Handler construction to new signature - Docs updated: - added explicit target_id scoping guidance for discovery/catalog/agent/llm workflows - clarified protocol-aware routing and noted legacy examples still present in large script docs Build validation: - Recompiled changed objects with PROXYSQLGENAI=1: - Query_Tool_Handler.oo - Discovery_Schema.oo - PgSQL_Static_Harvester.oo - ProxySQL_MCP_Server.oo	4 months ago
