An autoshutdown mode is introduced in SObjectizer v.5.4.0. This mode is on by default. In this mode SObjectizer Environment automatically shuts down its work after deregistering the last working cooperation.

This simplifies implementation of small programs with few cooperations inside (like small command-line utilities or tests): every cooperation deregisters iteself after finishing its work and SObjectizer is finished automatically.

If autoshutdown mode is not appropriate for the application it can be disabled by so_5::rt::so_environment_params_t::disable_autoshutdown() method:

so_5::api::run_so_environment(
  []( so_5::rt::so_environment_t & env ) { ... },
  []( so_5::rt::so_environment_params_t & params ) {
    params.disable_autoshutdown();
  } );
