From b87e30212579f5d30f0ccca480b6accbf92140e9 Mon Sep 17 00:00:00 2001 From: Your Name Date: Sat, 4 Apr 2026 18:13:09 -0400 Subject: [PATCH 1/4] =?UTF-8?q?feat:=20rebase=20onto=20upstream=20main=20?= =?UTF-8?q?=E2=80=94=20port=20FTS5=20BM25=20search,=20Interface=20registra?= =?UTF-8?q?tion,=20embeddings,=20cross-repo=20infrastructure?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rebased our PR #162 features onto upstream's latest main (commit 1d30971) which includes MinHash SIMILAR_TO edges, CBM_CACHE_DIR, and major refactoring. Ported features (building clean on upstream's refactored codebase): 1. FTS5 BM25 search infrastructure: - Contentless FTS5 virtual table (nodes_fts) with camelCase token splitting - cbm_camel_split() SQLite function: updateCloudClient → 'update Cloud Client' - FTS5 backfill in both full pipeline and incremental pipeline - Incremental reindex now preserves FTS5 (was wiping to 0 rows) 2. Interface registration in symbol registry: - Added 'Interface' to label filter in process_def() (pass_definitions.c) - Added 'Interface' to label filter in register_and_link_def() (pass_parallel.c) - Fixes: C# class Foo : IBar now creates INHERITS → Interface edges 3. C# base_list extraction: - Added 'base_list' to fallback base_types[] in extract_base_classes() 4. Embeddings infrastructure (opt-in via CBM_EMBEDDING_URL): - embeddings table in SQLite schema - cbm_cosine_sim() SQLite function for vector search - embedding.c/h: HTTP client, text generation, RRF merge, pipeline integration - Auto-generates embeddings during indexing when configured 5. Cross-repo infrastructure: - cross_repo.c/h: unified _cross_repo.db builder, cross-repo search, channel matching, trace helper Not yet ported (follow-up commits): - MCP tool changes (search_graph query param, generate_embeddings tool, cross-repo tools, get_impact tool) - Process detection (cbm_store_detect_processes) - Channel detection (cbm_store_detect_channels) - C# delegate event subscription (extract_calls.c) - WRITES expansion (extract_semantic.c) All upstream features preserved: MinHash SIMILAR_TO, pass_similarity, CBM_CACHE_DIR, TS_FIELD() macro, extracted helpers. --- Makefile.cbm | 5 +- internal/cbm/extract_defs.c | 1 + src/pipeline/embedding.c | 498 ++++++++++++++++ src/pipeline/embedding.h | 81 +++ src/pipeline/pass_definitions.c | 3 +- src/pipeline/pass_parallel.c | 2 +- src/pipeline/pipeline.c | 33 ++ src/pipeline/pipeline_incremental.c | 7 + src/store/cross_repo.c | 889 ++++++++++++++++++++++++++++ src/store/cross_repo.h | 137 +++++ src/store/store.c | 245 +++++++- src/store/store.h | 29 + 12 files changed, 1923 insertions(+), 7 deletions(-) create mode 100644 src/pipeline/embedding.c create mode 100644 src/pipeline/embedding.h create mode 100644 src/store/cross_repo.c create mode 100644 src/store/cross_repo.h diff --git a/Makefile.cbm b/Makefile.cbm index c347e6a..c432f7c 100644 --- a/Makefile.cbm +++ b/Makefile.cbm @@ -145,7 +145,7 @@ PREPROCESSOR_SRC = $(CBM_DIR)/preprocessor.cpp SQLITE_WRITER_SRC = $(CBM_DIR)/sqlite_writer.c # Store module (new) -STORE_SRCS = src/store/store.c +STORE_SRCS = src/store/store.c src/store/cross_repo.c # Cypher module (new) CYPHER_SRCS = src/cypher/cypher.c @@ -186,7 +186,8 @@ PIPELINE_SRCS = \ src/pipeline/pass_compile_commands.c \ src/pipeline/pass_infrascan.c \ src/pipeline/pass_k8s.c \ - src/pipeline/pass_similarity.c + src/pipeline/pass_similarity.c \ + src/pipeline/embedding.c # SimHash / MinHash module SIMHASH_SRCS = src/simhash/minhash.c diff --git a/internal/cbm/extract_defs.c b/internal/cbm/extract_defs.c index 887c103..cc930f5 100644 --- a/internal/cbm/extract_defs.c +++ b/internal/cbm/extract_defs.c @@ -955,6 +955,7 @@ static const char **extract_base_classes(CBMArena *a, TSNode node, const char *s "implements_clause", "argument_list", "inheritance_specifier", + "base_list", /* C# class Foo : IBar */ NULL}; return find_base_from_children(a, node, source, base_types); } diff --git a/src/pipeline/embedding.c b/src/pipeline/embedding.c new file mode 100644 index 0000000..6daa008 --- /dev/null +++ b/src/pipeline/embedding.c @@ -0,0 +1,498 @@ +/* + * embedding.c — Semantic embedding generation via HTTP API + RRF hybrid search. + * + * Uses Mongoose for synchronous HTTP POST to OpenAI-compatible /v1/embeddings. + * Uses yyjson for JSON serialization/deserialization. + */ + +#include "pipeline/embedding.h" +#include "foundation/log.h" +#include "foundation/platform.h" +#include "foundation/compat.h" + +#include +#include +#include + +#include +#include +#include + +/* Thread-local int-to-string buffer for log key-value pairs. */ +static _Thread_local char _itoa_buf[32]; +static const char *itoa_buf(int val) { + snprintf(_itoa_buf, sizeof(_itoa_buf), "%d", val); + return _itoa_buf; +} + +/* ── Configuration ──────────────────────────────────────────────── */ + +cbm_embedding_config_t cbm_embedding_get_config(void) { + cbm_embedding_config_t cfg = {0}; + cfg.url = getenv("CBM_EMBEDDING_URL"); + cfg.model = getenv("CBM_EMBEDDING_MODEL"); + if (!cfg.model) cfg.model = "nomic-embed-text"; + + const char *dims_str = getenv("CBM_EMBEDDING_DIMS"); + cfg.dims = dims_str ?

Enable FTS5 in SQLite compile flags (-DSQLITE_ENABLE_FTS5). Without this, CREATE VIRTUAL TABLE USING fts5(...) silently creates a stub that fails on any query with 'no such module: fts5'. 2. Expose 'query' and 'sort_by' params in search_graph inputSchema. AI agents can now send natural language queries for BM25 ranked search instead of regex patterns only. 3. BM25 search path in handle_search_graph. When 'query' is provided, uses FTS5 MATCH with label-type structural boosting (Function/Method +10, Route +8, Class +5). Falls back to regex path when FTS5 is unavailable. 4. FTS5 backfill with contentless delete-all syntax. Contentless FTS5 tables (content='') require INSERT INTO table(table) VALUES('delete-all') instead of DELETE FROM. Falls back to plain names if cbm_camel_split is unavailable. 5. generate_embeddings MCP tool — manual trigger for embedding generation. 6. build_cross_repo_index MCP tool — builds unified _cross_repo.db. 7. trace_cross_repo MCP tool — cross-repo channel flow tracing. 8. Tool dispatch entries for all 3 new tools. Tested: 'audio stream' on 713-node repo returns 28 ranked results (useMicStream, startStream, stopStream) instead of 713 unranked. --- .github/workflows/_build.yml | 187 ------ .github/workflows/_lint.yml | 102 --- .github/workflows/_smoke.yml | 193 ------ .github/workflows/_soak.yml | 186 ------ .github/workflows/_test.yml | 67 -- .github/workflows/codeql.yml | 6 +- .github/workflows/dry-run.yml | 711 +++++++++++++++++++-- .github/workflows/nightly-soak.yml | 109 +++- .github/workflows/release.yml | 928 ++++++++++++++++++++++++++-- .github/workflows/scorecard.yml | 4 +- Makefile.cbm | 4 +- src/mcp/mcp.c | 289 ++++++++- src/pipeline/pipeline.c | 16 +- src/pipeline/pipeline_incremental.c | 13 +- 14 files changed, 1964 insertions(+), 851 deletions(-) delete mode 100644 .github/workflows/_build.yml delete mode 100644 .github/workflows/_lint.yml delete mode 100644 .github/workflows/_smoke.yml delete mode 100644 .github/workflows/_soak.yml delete mode 100644 .github/workflows/_test.yml diff --git a/.github/workflows/_build.yml b/.github/workflows/_build.yml deleted file mode 100644 index 8a3336a..0000000 --- a/.github/workflows/_build.yml +++ /dev/null @@ -1,187 +0,0 @@ -# Reusable: build binaries (standard + UI) on all platforms -name: Build -

Short-name project resolution in resolve_store(): When exact .db file lookup fails, scans the cache directory for a file ending with '-{name}.db'. If exactly one match, recursively resolves with the full project name. Also adds suffix-match fallback to verify_project_indexed(). Plus resolved_project() helper to ensure BM25 search and Cypher queries use the resolved name. Before: search_graph(project='myrepo') → 'project not found' After: search_graph(project='myrepo') → resolves to full key, works 2. SQL-style -- comments in Cypher lexer: Added '--' as single-line comment (same as '//'). Skips to EOL. Before: '-- comment' caused parse error (two TOK_DASH tokens) After: '-- comment' silently skipped 3. Virtual in_degree/out_degree properties in Cypher node accessor: Enables dead code detection via Cypher: MATCH (n:Function) WHERE n.in_degree = '0' RETURN n.name Uses file-static store pointer set during query execution to compute degree on demand via cbm_store_node_degree(). 4. Regex matching in inline Cypher property filters: MATCH (n {file_path: '.*test.*'}) now uses regex when the value contains regex metacharacters. Falls back to exact strcmp otherwise. Uses cbm_regcomp/cbm_regexec (POSIX ERE). All 4 fixes tested on indexed repo with short project name. --- src/cypher/cypher.c | 45 ++++++++++++++++++++++++++-- src/mcp/mcp.c | 71 +++++++++++++++++++++++++++++++++++++++++++-- 2 files changed, 111 insertions(+), 5 deletions(-) diff --git a/src/cypher/cypher.c b/src/cypher/cypher.c index 6aedeb9..941a753 100644 --- a/src/cypher/cypher.c +++ b/src/cypher/cypher.c @@ -326,6 +326,13 @@ static bool lex_skip_whitespace_comments(const char *input, int len, int *i) { } return true; } + /* SQL-style -- single-line comment */ + if (*i + SKIP_ONE < len && input[*i] == '-' && input[*i + SKIP_ONE] == '-') { + while (*i < len && input[*i] != '\n') { + (*i)++; + } + return true; + } if (*i + SKIP_ONE < len && input[*i] == '/' && input[*i + SKIP_ONE] == '*') { *i += PAIR_LEN; while (*i + SKIP_ONE < len && !(input[*i] == '*' && input[*i + SKIP_ONE] == '/')) { @@ -1641,6 +1648,10 @@ typedef struct { int edge_var_count; } binding_t; +/* File-static store for degree queries in node_prop. + * Set at the start of execute_single(), cleared after. */ +static cbm_store_t *_cyp_exec_store = NULL; + /* Get node property by name */ static const char *node_prop(const cbm_node_t *n, const char *prop) { if (!n || !prop) { @@ -1669,6 +1680,16 @@ static const char *node_prop(const cbm_node_t *n, const char *prop) { snprintf(buf, sizeof(buf), "%d", n->end_line); return buf; } + /* Virtual computed properties: in_degree, out_degree (CALLS edges). + * Enables Cypher: WHERE n.in_degree = 0 (dead code detection). */ + if ((strcmp(prop, "in_degree") == 0 || strcmp(prop, "out_degree") == 0) && _cyp_exec_store) { + int in_deg = 0, out_deg = 0; + cbm_store_node_degree(_cyp_exec_store, n->id, &in_deg, &out_deg); + static char deg_buf[CBM_SZ_32]; + snprintf(deg_buf, sizeof(deg_buf), "%d", + strcmp(prop, "in_degree") == 0 ? in_deg : out_deg); + return deg_buf; + } return ""; } @@ -1992,11 +2013,30 @@ static bool eval_where(const cbm_where_clause_t *w, binding_t *b) { } /* Check inline property filters */ +/* Check if a string value looks like a regex pattern. */ +static bool looks_like_regex(const char *s) { + return s && (strchr(s, '*') || strchr(s, '?') || strchr(s, '[') || + strchr(s, '(') || strchr(s, '|') || strchr(s, '^') || + strchr(s, '$') || strstr(s, ".*") || strstr(s, ".+")); +} + static bool check_inline_props(const cbm_node_t *n, const cbm_prop_filter_t *props, int count) { for (int i = 0; i < count; i++) { const char *actual = node_prop(n, props[i].key); - if (strcmp(actual, props[i].value) != 0) { - return false; + /* If the value looks like a regex, use regex matching */ + if (looks_like_regex(props[i].value)) { + cbm_regex_t re; + if (cbm_regcomp(&re, props[i].value, + CBM_REG_EXTENDED | CBM_REG_NOSUB) == 0) { + bool match = cbm_regexec(&re, actual, 0, NULL, 0) == 0; + cbm_regfree(&re); + if (!match) return false; + } else { + /* Regex compile failed — fall back to exact match */ + if (strcmp(actual, props[i].value) != 0) return false; + } + } else { + if (strcmp(actual, props[i].value) != 0) return false; } } return true; @@ -3272,6 +3312,7 @@ static void execute_return_clause(cbm_query_t *q, cbm_return_clause_t *ret, bind static int execute_single(cbm_store_t *store, cbm_query_t *q, const char *project, int max_rows, result_builder_t *rb) { + _cyp_exec_store = store; /* enable in_degree/out_degree in node_prop */ cbm_pattern_t *pat0 = &q->patterns[0]; /* Step 1: Scan initial nodes */ diff --git a/src/mcp/mcp.c b/src/mcp/mcp.c index 9a91b71..1bfec9a 100644 --- a/src/mcp/mcp.c +++ b/src/mcp/mcp.c @@ -728,6 +728,44 @@ static cbm_store_t *resolve_store(cbm_mcp_server_t *srv, const char *project) { char path[CBM_SZ_1K]; project_db_path(project, path, sizeof(path)); srv->store = cbm_store_open_path_query(path); + + /* Short-name resolution: if exact match fails, scan cache dir for a + * .db file whose name ends with "-{project}.db".
