test_control_plugin is designed to cause a graceful shutdown when reaching a particular block in a sequence of blocks produced by a specific block producer. It can be invoked to either shutdown on the head block or the last irreversible block.
This is intended for testing, to determine exactly when a
nodeos instance will shutdown.
# config.ini plugin = eosio::test_control_plugin
# command-line nodeos ... --plugin eosio::test_control_plugin
# config.ini plugin = eosio::chain_plugin [options]
# command-line nodeos ... --plugin eosio::chain_plugin [operations] [options]
