Description

_startupComponent currently resets the unique_ptr if the component's startup() returns an error but not when the parent component is shutting down. This usually doesn't pose a problem except when the sub component is holding some resource that needs to be released if we decide not to proceed with calling its startup().

https://github.com/mongodb/mongo/blob/fa2dcc33303dd6a2080c108e121da6984d08a9d6/src/mongo/db/repl/initial_syncer.cpp#L1340


template <typename Component>
Status InitialSyncer::_startupComponent_inlock(Component& component) {
    if (_isShuttingDown_inlock()) {
        return Status(ErrorCodes::CallbackCanceled,
                      "initial syncer shutdown while trying to call startup() on component");
    }
    auto status = component->startup();
    if (!status.isOK()) {
        component.reset();
    }
    return status;
}
