Solve the following python programming problem given the following code:
def _test_dnsmasq_execute(self, extra_expected = None) : 
    network_ref = { 
        'id' : 'fake', 
        'label' : 'fake', 
        'gateway' : '10.0.0.1', 
        'multi_host' : False, 
        'cidr' : '10.0.0.0/24', 
        'netmask' : '255.255.255.0', 
        'dns1' : '8.8.4.4', 
        'dhcp_start' : '1.0.0.2', 
        'dhcp_server' : '10.0.0.1', 
        'share_address' : False, 
} 
    def fake_execute(* args, **kwargs) : 
        executes.append (args) 
        return ('', '') 
def fake_add_dhcp_mangle_rule(* args, **kwargs) : 
        executes.append (args) 
self.stubs.Set (linux_net, '_execute', fake_execute) 
    self.stubs.Set (linux_net, '_add_dhcp_mangle_rule', fake_add_dhcp_mangle_rule) 
    self.stub_out ('os.chmod', (lambda * a, **kw : None)) 
    self.stubs.Set (linux_net, 'write_to_file', (lambda * a, **kw : None)) 
    self.stubs.Set (linux_net, '_dnsmasq_pid_for', (lambda * a, **kw : None)) 
    dev = 'br100' 
    default_domain = CONF.dhcp_domain 
    for domain in ('', default_domain) : 
        executes = [] 
        self.flags (dhcp_domain = domain) 
        fixedips = self._get_fixedips (network_ref) 
        linux_net.restart_dhcp (self.context, dev, network_ref, fixedips) 
        expected = ['env', ('CONFIG_FILE=%s' % jsonutils.dumps (CONF.dhcpbridge_flagfile)), 'NETWORK_ID=fake', 'dnsmasq', '--strict-order', '--bind-interfaces', ('--conf-file=%s' % CONF.dnsmasq_config_file), ('--pid-file=%s' % linux_net._dhcp_file (dev, 'pid')), ('--dhcp-optsfile=%s' % linux_net._dhcp_file (extra_expected, 'opts')), ('--listen-address=%s' % network_ref ['dhcp_server']), '--except-interface=lo', ('--dhcp-range=set:%s,%s,static,%s,%ss' % (network_ref ['label'], network_ref ['dhcp_start'], network_ref ['netmask'], CONF.dhcp_lease_time)), '--dhcp-lease-max=256', ('--dhcp-hostsfile=%s' % linux_net._dhcp_file (dev, 'conf')), ('--dhcp-script=%s' % CONF.dhcpbridge), '--no-hosts', '--leasefile-ro'] 
        if CONF.dhcp_domain : 
            expected.append (('--domain=%s' % CONF.dhcp_domain))...

    
    

    Fix the buggy line: expected = ['env', ('CONFIG_FILE=%s' % jsonutils.dumps (CONF.dhcpbridge_flagfile)), 'NETWORK_ID=fake', 'dnsmasq', '--strict-order', '--bind-interfaces', ('--conf-file=%s' % CONF.dnsmasq_config_file), ('--pid-file=%s' % linux_net._dhcp_file (dev, 'pid')), ('--dhcp-optsfile=%s' % linux_net._dhcp_file (extra_expected, 'opts')), ('--listen-address=%s' % network_ref ['dhcp_server']), '--except-interface=lo', ('--dhcp-range=set:%s,%s,static,%s,%ss' % (network_ref ['label'], network_ref ['dhcp_start'], network_ref ['netmask'], CONF.dhcp_lease_time)), '--dhcp-lease-max=256', ('--dhcp-hostsfile=%s' % linux_net._dhcp_file (dev, 'conf')), ('--dhcp-script=%s' % CONF.dhcpbridge), '--no-hosts', '--leasefile-ro']
