It processes TASKs sequentially against a single VIM. -The tasks are stored at database in table vim_wim_actions -Several vim_wim_actions can refer to the same element at VIM (flavor, network, ...). This is somethng to avoid if RO -is migrated to a non-relational database as mongo db. Each vim_wim_actions reference a different instance_Xxxxx -In this case "related" colunm contains the same value, to know they refer to the same vim. In case of deletion, it -there is related tasks using this element, it is not deleted, The vim_info needed to delete is transfered to other task - -The task content is (M: stored at memory, D: stored at database): - MD instance_action_id: reference a global action over an instance-scenario: database instance_actions - MD task_index: index number of the task. This together with the previous forms a unique key identifier - MD datacenter_vim_id: should contain the uuid of the VIM managed by this thread - MD vim_id: id of the vm,net,etc at VIM - MD item: database table name, can be instance_vms, instance_nets, TODO: datacenter_flavors, datacenter_images - MD item_id: uuid of the referenced entry in the previous table - MD action: CREATE, DELETE, FIND - MD status: SCHEDULED: action need to be done - BUILD: not used - DONE: Done and it must be polled to VIM periodically to see status. ONLY for action=CREATE or FIND - FAILED: It cannot be created/found/deleted - FINISHED: similar to DONE, but no refresh is needed anymore. Task is maintained at database but - it is never processed by any thread - SUPERSEDED: similar to FINSISHED, but nothing has been done to completed the task. - MD extra: text with yaml format at database, dict at memory with: - params: list with the params to be sent to the VIM for CREATE or FIND. For DELETE the vim_id is taken - from other related tasks - find: (only for CREATE tasks) if present it should FIND before creating and use if existing. Contains - the FIND params - depends_on: list with the 'task_index'es of tasks that must be completed before. e.g. a vm creation depends - on a net creation - can contain an int (single index on the same instance-action) or str (compete action ID) - sdn_net_id: used for net. - interfaces: used for VMs. Each key is the uuid of the instance_interfaces entry at database - iface_id: uuid of intance_interfaces - sdn_port_id: - sdn_net_id: - vim_info - created_items: dictionary with extra elements created that need to be deleted. e.g. ports, volumes,... - created: False if the VIM element is not created by other actions, and it should not be deleted - vim_status: VIM status of the element. Stored also at database in the instance_XXX - vim_info: Detailed information of a vm/net from the VIM. Stored at database in the instance_XXX but not at - vim_wim_actions - M depends: dict with task_index(from depends_on) to dependency task - M params: same as extra[params] - MD error_msg: descriptive text upon an error.Stored also at database instance_XXX - MD created_at: task creation time. The task of creation must be the oldest - MD modified_at: next time task need to be processed. For example, for a refresh, it contain next time refresh must - be done - MD related: All the tasks over the same VIM element have same "related". Note that other VIMs can contain the - same value of related, but this thread only process those task of one VIM. Also related can be the - same among several NS os isntance-scenarios - MD worker: Used to lock in case of several thread workers. - -""" - -import threading -import time -import queue -import logging -from osm_ro_plugin import vimconn -from osm_ro_plugin.sdnconn import SdnConnectorError -import yaml -from osm_ro.db_base import db_base_Exception -from http import HTTPStatus -from copy import deepcopy -
