The feature is delivered as two linked pull requests because +the caller lives on v3.0 while reusable workflows live on `GH-Actions`. + +## Verification + +The existing group-registration lints must recognize the group. A focused +local `mysql84-binlog-g1` run with `COVERAGE=1` must pass the binlog-reader TAP +and produce a non-empty LCOV report. The reusable workflow is validated with +the existing Codecov workflow validator and static YAML checks. diff --git a/test/deps/cluster_simulator/tests/aurora_traffic_payloads/query_routing.json b/test/deps/cluster_simulator/tests/aurora_traffic_payloads/query_routing.json new file mode 100644 index 0000000000..640105618c --- /dev/null +++ b/test/deps/cluster_simulator/tests/aurora_traffic_payloads/query_routing.json @@ -0,0 +1,55 @@ +[ + { + "__comment__": "Aurora frontend routing: skip a high-lag reader and prefer a replica over the writer", + "cluster_type": "AURORA", + "mysql_servers": [ + { "hostgroup_id": 1271, "hostname": "host.1.11.aws-test.com", "port": 3306 }, + { "hostgroup_id": 1272, "hostname": "host.1.12.aws-test.com", "port": 3306 }, + { "hostgroup_id": 1272, "hostname": "host.1.13.aws-test.com", "port": 3306 }, + { "hostgroup_id": 1272, "hostname": "host.1.14.aws-test.com", "port": 3306 } + ], + "mysql_aws_aurora_hostgroups": [ + { + "writer_hostgroup": 1271, + "reader_hostgroup": 1272, + "active": 1, + "domain_name": ".aws-test.com", + "max_lag_ms": 100, + "writer_is_also_reader": 1, + "new_reader_weight": 1, + "add_lag_ms": 0, + "min_lag_ms": 0, + "comment": "" + } + ], + "mysql_monitor_config": [], + "aurora_servers_init_state": { + ".aws-test.com": [ + { "SERVER_ID": "host.1.11", "SESSION_ID": "MASTER_SESSION_ID", "REPLICA_LAG_IN_MILLISECONDS": 0 }, + { "SERVER_ID": "host.1.12", "SESSION_ID": "", "REPLICA_LAG_IN_MILLISECONDS": 0 }, + { "SERVER_ID": "host.1.13", "SESSION_ID": "", "REPLICA_LAG_IN_MILLISECONDS": 4 }, + { "SERVER_ID": "host.1.14", "SESSION_ID": "", "REPLICA_LAG_IN_MILLISECONDS": 50 } + ] + }, + "aurora_servers_new_state": { + ".aws-test.com": [ + { "SERVER_ID": "host.1.11", "SESSION_ID": "MASTER_SESSION_ID", "REPLICA_LAG_IN_MILLISECONDS": 0 }, + { "SERVER_ID": "host.1.12", "SESSION_ID": "", "REPLICA_LAG_IN_MILLISECONDS": 0 }, + { "SERVER_ID": "host.1.13", "SESSION_ID": "", "REPLICA_LAG_IN_MILLISECONDS": 4 }, + { "SERVER_ID": "host.1.14", "SESSION_ID": "", "REPLICA_LAG_IN_MILLISECONDS": 50 } + ] + }, + "proxysql_init_state": [ + { "hostgroup_id": 1271, "hostname": "host.1.11.aws-test.com", "port": 3306, "status": "ONLINE" }, + { "hostgroup_id": 1272, "hostname": "host.1.12.aws-test.com", "port": 3306, "status": "ONLINE" }, + { "hostgroup_id": 1272, "hostname": "host.1.13.aws-test.com", "port": 3306, "status": "ONLINE" }, + { "hostgroup_id": 1272, "hostname": "host.1.14.aws-test.com", "port": 3306, "status": "ONLINE" } + ], + "proxysql_final_state": [ + { "hostgroup_id": 1271, "hostname": "host.1.11.aws-test.com", "port": 3306, "status": "ONLINE" }, + { "hostgroup_id": 1272, "hostname": "host.1.12.aws-test.com", "port": 3306, "status": "ONLINE" }, + { "hostgroup_id": 1272, "hostname": "host.1.13.aws-test.com", "port": 3306, "status": "ONLINE" }, + { "hostgroup_id": 1272, "hostname": "host.1.14.aws-test.com", "port": 3306, "status": "ONLINE" } + ] + } +] diff --git a/test/infra/control/validate-codecov-workflows.bash b/test/infra/control/validate-codecov-workflows.bash index a36d5179f5..86fe8f3735 100755 --- a/test/infra/control/validate-codecov-workflows.bash +++ b/test/infra/control/validate-codecov-workflows.bash @@ -3,15 +3,10 @@ set -euo pipefail WORKFLOW_ROOT="${1:-.github/workflows}" EXPECTED_CONFIG="${2:-codecov.yml}" -if [ "$#" -ge 3 ];
