Attila Fazekas f750a6fedb Already dead process tolerance in unstack.sh
The gate/updown.sh calls the unstack.sh with
-ex option. Normally we do not use -e with unstack.sh.

The unstack.sh can fail if the service already stopped,
and it also can have flaky failures on the gate.

For example the stop_swift function tries to kill swift in two
different ways, and if the first one succeeds before the 2th attempt
the pkill fails the whole unstack.sh.

This change accepts kill failure.
Normally the kill can fail if the process does not exits,
or when you do not have permission to the kill operation.

Since the permission issue is very unlikely in our case,
this change does not tries to distinguish the two operation.

The behavior of the unstack.sh wen you are not using -ex should
not be changed by this change.

Neutron plugin specific files

Neutron plugins require plugin specific behavior. The files under the directory, lib/neutron_plugins/, will be used when their service is enabled. Each plugin has lib/neutron_plugins/$Q_PLUGIN and define the following functions. Plugin specific configuration variables should be in this file.

  • filename: $Q_PLUGIN
    • The corresponding file name MUST be the same to plugin name $Q_PLUGIN. Plugin specific configuration variables should be in this file.

functions

lib/neutron-legacy calls the following functions when the $Q_PLUGIN is enabled

  • neutron_plugin_create_nova_conf : set NOVA_VIF_DRIVER and optionally set options in nova_conf e.g. NOVA_VIF_DRIVER=${NOVA_VIF_DRIVER:-"nova.virt.libvirt.vif.LibvirtGenericVIFDriver"}
  • neutron_plugin_install_agent_packages : install packages that is specific to plugin agent e.g. install_package bridge-utils
  • neutron_plugin_configure_common : set plugin-specific variables, Q_PLUGIN_CONF_PATH, Q_PLUGIN_CONF_FILENAME, Q_PLUGIN_CLASS
  • neutron_plugin_configure_debug_command
  • neutron_plugin_configure_dhcp_agent
  • neutron_plugin_configure_l3_agent
  • neutron_plugin_configure_plugin_agent
  • neutron_plugin_configure_service
  • neutron_plugin_setup_interface_driver
  • has_neutron_plugin_security_group: return 0 if the plugin support neutron security group otherwise return 1
  • neutron_plugin_check_adv_test_requirements: return 0 if requirements are satisfied otherwise return 1
