Add 11 new CROSS_* edge type constants for messaging protocols (KAFKA, SQS, SNS, EVENTBRIDGE, PUBSUB, AMQP, MQTT, NATS, REDIS_PUBSUB, WS, SSE). Each match emits two intra-DB edges anchored on synthetic MessagingChannel nodes (QN __channel____), mirroring the upstream HTTP Route-node pattern. Producer DB gets function -> channel; consumer DB gets channel -> function. Cross-project metadata lives in edge properties JSON. The matcher now skips http/grpc/graphql/trpc protocols entirely; those are owned by the upstream Route-QN matcher in pass_cross_repo.c. --- src/pipeline/pass_cross_repo.c | 36 ++ src/pipeline/pass_cross_repo.h | 35 ++ src/pipeline/pass_crossrepolinks.c | 656 +++++++++++++-------------- tests/test_cross_project_links.c | 700 ++++++++++++++--------------- 4 files changed, 740 insertions(+), 687 deletions(-) diff --git a/src/pipeline/pass_cross_repo.c b/src/pipeline/pass_cross_repo.c index 07f5ca7e..504f0df8 100644 --- a/src/pipeline/pass_cross_repo.c +++ b/src/pipeline/pass_cross_repo.c @@ -39,6 +39,42 @@ enum { #define CR_MS_PER_SEC 1000.0 #define CR_NS_PER_MS 1000000.0 +/* ── Messaging protocol → CROSS_* edge type mapping ────────────── + * + * Upstream owns HTTP/gRPC/GraphQL/tRPC via Route-QN matching, so those + * protocols are intentionally absent from this mapping: the messaging + * matcher in pass_crossrepolinks.c skips them via + * cbm_messaging_protocol_to_cross_edge() returning NULL, leaving upstream + * as the sole source of their CROSS_* edges. + */ +const char *const CBM_MESSAGING_CROSS_EDGE_TYPES[CBM_MESSAGING_CROSS_EDGE_TYPE_COUNT] = { + CBM_EDGE_CROSS_KAFKA_CALLS, CBM_EDGE_CROSS_SQS_CALLS, + CBM_EDGE_CROSS_SNS_CALLS, CBM_EDGE_CROSS_EVENTBRIDGE_CALLS, + CBM_EDGE_CROSS_PUBSUB_CALLS, CBM_EDGE_CROSS_AMQP_CALLS, + CBM_EDGE_CROSS_MQTT_CALLS, CBM_EDGE_CROSS_NATS_CALLS, + CBM_EDGE_CROSS_REDIS_PUBSUB_CALLS, CBM_EDGE_CROSS_WS_CALLS, + CBM_EDGE_CROSS_SSE_CALLS, +}; + +const char *cbm_messaging_protocol_to_cross_edge(const char *protocol) { + if (!protocol) { + return NULL; + } + if (strcmp(protocol, "kafka") == 0) return CBM_EDGE_CROSS_KAFKA_CALLS; + if (strcmp(protocol, "sqs") == 0) return CBM_EDGE_CROSS_SQS_CALLS; + if (strcmp(protocol, "sns") == 0) return CBM_EDGE_CROSS_SNS_CALLS; + if (strcmp(protocol, "eventbridge") == 0) return CBM_EDGE_CROSS_EVENTBRIDGE_CALLS; + if (strcmp(protocol, "pubsub") == 0) return CBM_EDGE_CROSS_PUBSUB_CALLS; + if (strcmp(protocol, "rabbitmq") == 0) return CBM_EDGE_CROSS_AMQP_CALLS; + if (strcmp(protocol, "amqp") == 0) return CBM_EDGE_CROSS_AMQP_CALLS; + if (strcmp(protocol, "mqtt") == 0) return CBM_EDGE_CROSS_MQTT_CALLS; + if (strcmp(protocol, "nats") == 0) return CBM_EDGE_CROSS_NATS_CALLS; + if (strcmp(protocol, "redis_pubsub") == 0) return CBM_EDGE_CROSS_REDIS_PUBSUB_CALLS; + if (strcmp(protocol, "ws") == 0) return CBM_EDGE_CROSS_WS_CALLS; + if (strcmp(protocol, "sse") == 0) return CBM_EDGE_CROSS_SSE_CALLS; + return NULL; +} + /* TLS buffer for integer-to-string in log calls. */ static CBM_TLS char cr_ibuf[CBM_SZ_32]; static const char *cr_itoa(int v) { diff --git a/src/pipeline/pass_cross_repo.h b/src/pipeline/pass_cross_repo.h index 5d2d4cfe..8c35b529 100644 --- a/src/pipeline/pass_cross_repo.h +++ b/src/pipeline/pass_cross_repo.h @@ -7,6 +7,41 @@ #include "store/store.h" +/* ── CROSS_* edge type names ───────────────────────────────────── + * + * Upstream Route-QN matcher emits the first six.
