The upgrade check asserts that the server log contains no <Error> lines.
Test 04210_show_remote_databases_in_system_tables creates two remote database
engines pointing at the deliberately unreachable host 192.0.2.1 (RFC5737
TEST-NET-1):
- ENGINE = PostgreSQL('192.0.2.1:5432', ...)
- ENGINE = MySQL('192.0.2.1:3306', ...)
PostgreSQL: DatabasePostgreSQL::loadStoredObjects activates the
removeOutdatedTables cleaner task, whose periodic pool->get() times out against
the unreachable host and logs <Error> for each retry, including right after the
upgrade restart reloads the persisted engine.
MySQL: the engine probes the server while loading the persisted object after the
upgrade restart, logging <Error> from mysqlxx::Pool, the PoolWithFailover retry
logger, and the DatabaseMySQL ALL_CONNECTION_TRIES_FAILED exception.
The upgrade-test environment has no real PostgreSQL or MySQL server, so these
connection errors are fixture noise, not a compatibility regression (real
PostgreSQL/MySQL regressions are covered by integration tests with a live server).
Allowlist them in upgrade_runner.sh by requiring the component AND the
connection-failure symptom together, so genuine DatabasePostgreSQL/DatabaseMySQL
errors (logic, parsing, a different error code) still surface.
