-This is thread that interacts with a VIM. 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- SUPERSEDED: similar to FINSISHED, but nothing has been done to completed the task.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.
