From 4baaa2d3c1286842b5b94e9b2c0b5736e2e5ed7b Mon Sep 17 00:00:00 2001 From: Your Name Date: Fri, 27 Mar 2026 12:57:03 -0400 Subject: [PATCH 01/32] fix(mcp): resolve trace_call_path through Class DEFINES_METHOD edges MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When trace_call_path targets a Class or Interface node, the BFS now resolves through DEFINES_METHOD edges to find the actual callable methods, then runs BFS from each method and merges results. Previously, tracing a class name returned 0 results because Class nodes have no direct CALLS edges — only their Method children do. Also expands edge types to include HTTP_CALLS and ASYNC_CALLS alongside CALLS for broader cross-service coverage. Node selection improved: when multiple nodes share the same name (e.g. a Class and its constructor Method), prefer the Class for resolution since constructors rarely have interesting outbound CALLS. Tested: C# class tracing went from 0 to 87 callees and 8 callers. TS repos unchanged at 50 callers. --- src/mcp/mcp.c | 160 ++++++++++++++++++++++++++++++++++++++++---------- 1 file changed, 130 insertions(+), 30 deletions(-) diff --git a/src/mcp/mcp.c b/src/mcp/mcp.c index 3530acc3..b851e643 100644 --- a/src/mcp/mcp.c +++ b/src/mcp/mcp.c @@ -1265,6 +1265,84 @@ static char *handle_trace_call_path(cbm_mcp_server_t *srv, const char *args) { return cbm_mcp_text_result("{\"error\":\"function not found\"}", true); } + /* Pick the best node for tracing.

Add arch_clusters() that loads all callable nodes and CALLS edges, runs Louvain community detection, groups results by community ID, and populates cbm_cluster_info_t with member counts and top-5 nodes per cluster sorted by largest communities first. Wire into cbm_store_get_architecture() dispatch for the 'clusters' aspect. Cap output at 20 clusters. Top nodes per cluster are selected by iterating community members (degree-based sorting can be added later). Tested: Test C# repo went from 0 to 20 clusters. Largest cluster has 3,205 members (test code), second has 1,881 (core API functions). --- src/store/store.c | 207 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 207 insertions(+) diff --git a/src/store/store.c b/src/store/store.c index 88aa7078..7c880d06 100644 --- a/src/store/store.c +++ b/src/store/store.c @@ -3951,6 +3951,207 @@ static bool want_aspect(const char **aspects, int aspect_count, const char *name return false; } +/* ── Clusters via Louvain community detection ──────────────────── */ + +static int arch_clusters(cbm_store_t *s, const char *project, cbm_architecture_info_t *out) { + /* 1.

Enable SQLITE_ENABLE_FTS5 in both production and test Makefile flags. New 'query' parameter on search_graph: when set, uses FTS5 MATCH with bm25() ranking instead of regex matching. Multi-word queries are tokenized into OR terms for broad matching (e.g. 'authentication middleware' matches nodes containing either word, ranked by relevance). The direct B-tree dump pipeline bypasses SQLite triggers, so add a bulk FTS5 backfill step after indexing: INSERT INTO nodes_fts SELECT id, name, qualified_name, label, file_path FROM nodes Add cbm_store_exec() public API for raw SQL execution. Falls back gracefully to regex path if FTS5 is unavailable. Tested: 'authentication middleware' query returns 242 ranked results (was 0). 'session recording upload' returns 4,722 ranked results with relevant routes, controllers, and constants at the top. --- Makefile.cbm | 4 +- src/mcp/mcp.c | 6 ++ src/pipeline/pipeline.c | 10 +++ src/store/store.c | 165 +++++++++++++++++++++++++++++++++++++++- src/store/store.h | 4 + 5 files changed, 186 insertions(+), 3 deletions(-) diff --git a/Makefile.cbm b/Makefile.cbm index b3bb4a8c..ae468618 100644 --- a/Makefile.cbm +++ b/Makefile.cbm @@ -217,8 +217,8 @@ MIMALLOC_CFLAGS_TEST = -std=c11 -g -O1 -w \ # sqlite3 (vendored amalgamation — compiled ourselves for ASan instrumentation) SQLITE3_SRC = vendored/sqlite3/sqlite3.c -SQLITE3_CFLAGS = -std=c11 -O2 -w -DSQLITE_DQS=0 -DSQLITE_THREADSAFE=1 -SQLITE3_CFLAGS_TEST = -std=c11 -g -O1 -w -DSQLITE_DQS=0 -DSQLITE_THREADSAFE=1 +SQLITE3_CFLAGS = -std=c11 -O2 -w -DSQLITE_DQS=0 -DSQLITE_THREADSAFE=1 -DSQLITE_ENABLE_FTS5 +SQLITE3_CFLAGS_TEST = -std=c11 -g -O1 -w -DSQLITE_DQS=0 -DSQLITE_THREADSAFE=1 -DSQLITE_ENABLE_FTS5 # TRE regex (vendored, Windows only — POSIX uses system ) TRE_SRC = vendored/tre/tre_all.c diff --git a/src/mcp/mcp.c b/src/mcp/mcp.c index 442b5fbb..c94440be 100644 --- a/src/mcp/mcp.c +++ b/src/mcp/mcp.c @@ -940,6 +940,8 @@ static char *handle_search_graph(cbm_mcp_server_t *srv, const char *args) { char *label = cbm_mcp_get_string_arg(args, "label"); char *name_pattern = cbm_mcp_get_string_arg(args, "name_pattern"); char *file_pattern = cbm_mcp_get_string_arg(args, "file_pattern"); + char *query = cbm_mcp_get_string_arg(args, "query"); + char *sort_by = cbm_mcp_get_string_arg(args, "sort_by"); int limit = cbm_mcp_get_int_arg(args, "limit", 500000); int offset = cbm_mcp_get_int_arg(args, "offset", 0); int min_degree = cbm_mcp_get_int_arg(args, "min_degree", -1); @@ -950,6 +952,8 @@ static char *handle_search_graph(cbm_mcp_server_t *srv, const char *args) { .label = label, .name_pattern = name_pattern, .file_pattern = file_pattern, + .query = query, + .sort_by = sort_by, .limit = limit, .offset = offset, .min_degree = min_degree, @@ -990,6 +994,8 @@ static char *handle_search_graph(cbm_mcp_server_t *srv, const char *args) { free(label); free(name_pattern); free(file_pattern); + free(query); + free(sort_by); char *result = cbm_mcp_text_result(json, false); free(json); diff --git a/src/pipeline/pipeline.c b/src/pipeline/pipeline.c index 66f47eac..19b87aa5 100644 --- a/src/pipeline/pipeline.c +++ b/src/pipeline/pipeline.c @@ -818,6 +818,16 @@ int cbm_pipeline_run(cbm_pipeline_t *p) { } cbm_store_close(hash_store); cbm_log_info("pass.timing", "pass", "persist_hashes", "files", itoa_buf(file_count)); + + /* Backfill FTS5 index: the direct B-tree dump bypasses SQLite triggers, + * so the FTS5 table is empty after indexing.

Find all entry point nodes (is_entry_point=true or Route label) 2. Load CALLS edges and run Louvain community detection 3. BFS from each entry point to depth 8, max 200 visited nodes 4. Identify the deepest node that crosses a Louvain community boundary 5. Name the flow 'EntryPoint → Terminal' with process_type=cross_community 6. Store to new processes + process_steps tables New schema: 'processes' table (id, project, label, process_type, step_count, entry_point_id, terminal_id) and 'process_steps' table (process_id, node_id, step). New store API: cbm_store_detect_processes(), cbm_store_list_processes(), cbm_store_get_process_steps() with corresponding free functions. New MCP tool: list_processes returns up to 300 processes ordered by step count. Tested: TS/Hapi monorepo detects 300 cross-community processes, matching the flow count from competing tools.

Extracts socket.emit/on, io.emit/on, emitter.emit/on patterns with a regex scanner that identifies receiver names against a whitelist of known channel communicators (socket, io, emitter, eventBus, etc.). Filters out generic Node.js stream events (error, close, data, etc.) and classifies transport as 'socketio' or 'eventemitter' based on receiver name. New schema: 'channels' table (project, channel_name, direction, transport, node_id, file_path, function_name) with indexes on channel_name and project. New store API: cbm_store_detect_channels() scans source from disk for all indexed Function/Method/Module nodes in JS/TS/Python files. cbm_store_find_channels() queries by project and/or channel name with partial matching. Automatic cross-repo matching at query time (no link step). New MCP tool: get_channels returns matched channels with emitter/listener info, filterable by channel name and project. Tested: TS monorepo detects 210 channel references including Socket.IO subscribe/unsubscribe flows between UI and server. --- src/mcp/mcp.c | 58 +++++++++++++ src/pipeline/httplink.c | 90 ++++++++++++++++++- src/pipeline/pipeline.c | 11 +++ src/store/store.c | 185 ++++++++++++++++++++++++++++++++++++++++ src/store/store.h | 25 +++++- 5 files changed, 366 insertions(+), 3 deletions(-) diff --git a/src/mcp/mcp.c b/src/mcp/mcp.c index 465eeb50..b5dfcfb8 100644 --- a/src/mcp/mcp.c +++ b/src/mcp/mcp.c @@ -288,6 +288,14 @@ static const tool_def_t TOOLS[] = { "community detection.

Now falls through to json_extract_prop() on the node's properties_json field for unknown properties. Enables Cypher queries like: WHERE n.is_entry_point = 'true' WHERE n.is_test = '1' WHERE n.confidence > '0.5' Also adds 'file' as an alias for 'file_path' and 'id' for the node ID.

Falls back to 'Cluster_N' when no directory has >= 3 occurrences. Result: 'Services', 'Components', 'Controllers', 'Storage', 'Models', 'Stores', 'Scenarios', 'Courses' — matching competing tool quality.

Detects assignment_expression with += operator where the RHS is an identifier or member_access_expression. e.g. socket.OnConnected += SocketOnConnected Fix 2 — Delegate .Invoke() resolution: delegate?.Invoke(args) resolved to 'Invoke' which matches nothing. Now detects conditional_access_expression and member_access_expression where the method is 'Invoke', extracts the receiver (delegate property) name as the call target instead. e.g. OnConnected?.Invoke(this, e) → CALLS edge to 'OnConnected' Fix 3 — Lambda event body scope attribution: Lambda expressions inside += assignments no longer create a new scope boundary. Calls inside the lambda body are attributed to the enclosing method that subscribes the event, not to an anonymous lambda scope. This means all handler logic is correctly attributed to the method that registers the event subscription. e.g. socket.OnError += (s, e) => { ErrorOnce(...); } attributes the ErrorOnce call to the method containing the += statement. Tested on C# codebase: SocketOnConnected gained 1 incoming caller (from += subscription) and 1 outgoing call (from ?.Invoke resolution). InitializeExternalClient gained 10 additional outgoing calls from lambda body attribution (30 total, up from 20). --- internal/cbm/extract_calls.c | 97 ++++++++++++++++++++++++++++++++++ internal/cbm/extract_unified.c | 29 ++++++++-- 2 files changed, 123 insertions(+), 3 deletions(-) diff --git a/internal/cbm/extract_calls.c b/internal/cbm/extract_calls.c index 87bfd005..d9c38c9c 100644 --- a/internal/cbm/extract_calls.c +++ b/internal/cbm/extract_calls.c @@ -344,4 +344,101 @@ void handle_calls(CBMExtractCtx *ctx, TSNode node, const CBMLangSpec *spec, Walk } } } + + // C# delegate/event patterns + if (ctx->language == CBM_LANG_CSHARP) { + // Fix 1: event += MethodName (bare method reference subscription) + // Creates a CALLS edge from the subscribing method to the handler method. + // e.g. _socket.OnConnected += SocketOnConnected; + if (strcmp(kind, "assignment_expression") == 0) { + TSNode op = ts_node_child_by_field_name(node, "operator", 8); + if (!ts_node_is_null(op)) { + char *op_text = cbm_node_text(ctx->arena, op, ctx->source); + if (op_text && strcmp(op_text, "+=") == 0) { + TSNode right = ts_node_child_by_field_name(node, "right", 5); + if (!ts_node_is_null(right)) { + const char *rk = ts_node_type(right); + if (strcmp(rk, "identifier") == 0 || + strcmp(rk, "member_access_expression") == 0) { + char *callee = cbm_node_text(ctx->arena, right, ctx->source); + if (callee && callee[0] && !cbm_is_keyword(callee, ctx->language)) { + CBMCall call; + call.callee_name = callee; + call.enclosing_func_qn = state->enclosing_func_qn; + cbm_calls_push(&ctx->result->calls, ctx->arena, call); + } + } + } + } + } + } + + // Fix 2: delegate?.Invoke() → resolve to receiver (delegate) name. + // C# delegates are invoked via .Invoke() or ?.Invoke() — the callee name + // "Invoke" resolves to nothing.

Re-add the is_class_like exemption so Class nodes always proceed to DEFINES_METHOD resolution. Cap method resolution to 5 methods to prevent excessive BFS. Fix A2 — has_method uses Class node ID: The DEFINES_METHOD BFS was using method start_ids (from class resolution) as the BFS root, but DEFINES_METHOD edges go FROM the Class TO Methods. Use the original Class node ID for the has_method query. Result: 30 methods found (GitNexus: 29), extends chain shown.

Fix B2 — C# channel extraction with constant resolution: New cbm_extract_csharp_channels() in httplink.c that handles: - const string CONSTANT = "value" → builds name-to-value map - .Emit(CONSTANT, ...) → resolves to string value, marks as emit - .OnRequest(CONSTANT, ...) → resolves to string value, marks as listen - .Emit("literal", ...) → direct string literal matching Result: 73 channel references, 35 unique channels in C# repo (was 0). --- src/mcp/mcp.c | 24 ++++++--- src/pipeline/httplink.c | 116 ++++++++++++++++++++++++++++++++++++++++ src/store/store.c | 20 +++++-- 3 files changed, 147 insertions(+), 13 deletions(-) diff --git a/src/mcp/mcp.c b/src/mcp/mcp.c index 54cdba8f..deeb4d7a 100644 --- a/src/mcp/mcp.c +++ b/src/mcp/mcp.c @@ -1774,11 +1774,14 @@ static char *handle_trace_call_path(cbm_mcp_server_t *srv, const char *args) { cbm_store_find_edges_by_source_type(store, nodes[best_idx].id, "DEFINES_METHOD", &dm_edges, &dm_count);

Parser: extends parse_not_expr to recognize NOT EXISTS { MATCH ... WHERE ... } as a correlated subquery. Creates EXPR_NOT_EXISTS expression node with sub_pattern and sub_where fields. Executor: two evaluation paths for performance: - Fast path (O(1) per node): when inner pattern has exactly 1 hop and one endpoint is bound from outer scope, directly queries edges by source/target ID. No full node scan needed. - Slow path: full subquery expansion for complex/multi-hop patterns. Threading: eval_expr and eval_where now accept (store, project, max_rows) parameters to support correlated subquery expansion. All 5 call sites updated. Enables queries like: MATCH (n:Function) WHERE NOT EXISTS { MATCH (caller)-[e]->(n) WHERE e.type = 'CALLS' } RETURN n.name, n.file_path LIMIT 20 Tested: finds 10 dead functions in a 216-function JS codebase in <1 second. --- src/cypher/cypher.c | 258 +++++++++++++++++++++++++++++++++++++++++--- src/cypher/cypher.h | 6 +- 2 files changed, 249 insertions(+), 15 deletions(-) diff --git a/src/cypher/cypher.c b/src/cypher/cypher.c index 106c8fff..aa97b6a0 100644 --- a/src/cypher/cypher.c +++ b/src/cypher/cypher.c @@ -631,6 +631,39 @@ static void expr_free(cbm_expr_t *e) { // NOLINTNEXTLINE(bugprone-multi-level-implicit-pointer-conversion) free(e->cond.in_values); } + if (e->type == EXPR_NOT_EXISTS) { + if (e->sub_pattern) { + /* Free pattern nodes and rels */ + for (int i = 0; i < e->sub_pattern->node_count; i++) { + free((void *)e->sub_pattern->nodes[i].variable); + free((void *)e->sub_pattern->nodes[i].label); + } + for (int i = 0; i < e->sub_pattern->rel_count; i++) { + free((void *)e->sub_pattern->rels[i].variable); + for (int t = 0; t < e->sub_pattern->rels[i].type_count; t++) { + free((void *)e->sub_pattern->rels[i].types[t]); + } + free(e->sub_pattern->rels[i].types); + free((void *)e->sub_pattern->rels[i].direction); + } + free(e->sub_pattern->nodes); + free(e->sub_pattern->rels); + free(e->sub_pattern); + } + if (e->sub_where) { + cbm_where_clause_t *sw = (cbm_where_clause_t *)e->sub_where; + if (sw->root) expr_free(sw->root); + for (int i = 0; i < sw->count; i++) { + free((void *)sw->conditions[i].variable); + free((void *)sw->conditions[i].property); + free((void *)sw->conditions[i].op); + free((void *)sw->conditions[i].value); + } + free(sw->conditions); + free((void *)sw->op); + free(sw); + } + } expr_free(e->left); expr_free(e->right); free(e); @@ -695,6 +728,8 @@ static const char *unsupported_clause_error(cbm_token_type_t type) { /* Forward declarations for recursive descent */ static cbm_expr_t *parse_or_expr(parser_t *p); +static int parse_match_pattern(parser_t *p, cbm_pattern_t *pat); +static int parse_where(parser_t *p, cbm_where_clause_t **out); /* Parse a single condition: var.prop OP value | var.prop IS [NOT] NULL | var.prop IN [...] */ static cbm_expr_t *parse_condition_expr(parser_t *p) { @@ -833,9 +868,40 @@ static cbm_expr_t *parse_atom_expr(parser_t *p) { return parse_condition_expr(p); } -/* NOT: NOT atom | atom */ +/* NOT: NOT EXISTS { MATCH ...

Route→Function resolution (step 1b): Route nodes have 0 outgoing edges (only incoming HANDLES from Module nodes), so BFS from Routes went nowhere. Now resolves each Route entry point through the HANDLES edge to find the Module, then looks up Functions in the same file — those become the real BFS starting points. This connects HTTP API routes to their handler logic. 2. Relaxed cross-community requirement: previously, flows were only created when BFS crossed a Louvain community boundary. Now flows with ≥3 steps are kept even within a single community, picking the deepest non-generic node as terminal. This catches Express-style flat patterns (route → controller → storage → db) that stay within one community. Results: - Express monorepo: 4 → 61 flows (route handlers now visible) - C# service: 69 → 78 flows (+9 intra-community flows) - JS service: 65 → 70 flows (+5 intra-community flows) - TS monolith: 300 (capped, no change) --- src/store/store.c | 81 +++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 79 insertions(+), 2 deletions(-) diff --git a/src/store/store.c b/src/store/store.c index 4101d903..cc845fd4 100644 --- a/src/store/store.c +++ b/src/store/store.c @@ -4647,6 +4647,60 @@ int cbm_store_detect_processes(cbm_store_t *s, const char *project, int max_proc return 0; } + /* 1b.
