Method initConnsMap

server/server.go:737–742

initConnsMap initializes the connection registry map. This is a separate method to work around cases where a local variable named "clientConn" shadows the type name (e.g., in worker.go).

()

// ActiveConnections returns the number of active connections
func (s *Server) ActiveConnections() int64 {
	return atomic.LoadInt64(&s.activeConns)
}

// RegisterQuery registers a cancel function for a backend key.
// This allows the query to be cancelled via a cancel request from another connection.
func (s *Server) RegisterQuery(key BackendKey, cancel context.CancelFunc) {
	s.activeQueriesMu.Lock()
	// Lazily initialized: production servers get the map from New, but test
	// fixtures (and InitMinimalServer paths) may construct a bare Server.
