* Maintenance Window: Introduced dynamic update to polling time. (#245)
Resolves#245
Added new configuration parameters and controller handling that can be
used to enable reduction in polling time near to start of a maintenance
window.
- The device may only get to know of start of maintenance window when
the device polls the server. If a window is available, server responds
with maintenanceWindow as 'available' and the update as 'forced'. Hence,
as the time for start of a maintenance window approaches, the device
should poll the server more often in order to decrease the possibility
of missing the maintenance window start time due to non-alignment of
polling with the start time, or due to packet losses and other network
issues.
- Additional configuration parameter is introduced that will be used to
specify the minimum number of times the controller should poll between
current time and the start of maintenance window. Using this parameter,
an "inverse exponential back-off" scheme for reducing the polling time
is implemented.
- Implemented inverse exponential back-off for polling.
For example, considering default polling-time = 00:05:00,
min-polling-time = 00:00:30, maintenance-window-poll-count = 3, we
expect that controller should poll the server 3 times between current
time and start of a maintenance window. Thus in following scenario
controller will get to know of start of maintenance 3 secs after
scheduled start. Whereas without this scheme, delay may be as much as 4
minutes.
time until start: 00:21:00; polling time: 00:05:00
time until start: 00:16:00; polling time: 00:05:00
time until start: 00:11:00; polling time: 00:03:40
time until start: 00:07:20; polling time: 00:02:27
time until start: 00:04:53; polling time: 00:01:38
time until start: 00:02:10; polling time: 00:00:43
time until start: 00:01:27; polling time: 00:00:30
time until start: 00:00:57; polling time: 00:00:30
time until start: 00:00:27; polling time: 00:00:30
time until start: -00:00:03; polling time: 00:05:00
- Once a maintenance window starts, the polling time is reverted to
default. Polling time is not changed near the end of a maintenance
window.

* Maintenance Window: Updated the DMF API.
Added maintenance window handling for DMF API. Currently no timer or
scheduler is used to send updates to devices when a maintenance window
becomes available. The device can simulate a poll behaviour by sending a
message on UPDATE_ACTION_STATUS topic. Depending on whether there is a
maintenance window available or not, server should send
DOWNLOAD_AND_INSTALL or DOWNLOAD_AND_SKIP.
- Additional action status (DOWNLOADED) and event topic
(DOWNLOAD_AND_SKIP)
- Server sends DOWNLOAD_AND_SKIP or DOWNLOAD_AND_INSTALL based on
maintenance window using ControllerManagement

* Maintenance Window: Added new fields, enums, APIs and helper classes.
Extended the data model and Action API to support maintenance schedule.
Also provided helper classes to parse cron expression and calculate
maintenance window based on the schedule.
- DOWNLOADED status added to Action interface for controller to record
action status.
- Extra fields and APIs are added to Action to set schedule, duration
and time zone of maintenance window.
- Maintenance schedule can be defined using: a cron expression (e.g. "0
30 10-13 ? * WED,FRI" for 30 minutes past the hour, between 10:00 AM
and 01:59 PM, only on Wednesday and Friday), a duration (e.g. "00:30:00"
for 30 minutes) and the time zone (e.g. "+02:00" for CET summer time or
"+00:00" for UTC) relative to which maintenance window start time is
calculated.
- Extra APIs added to check if a maintenance schedule is defined or
lapsed and if a maintenance window is available based on the schedule.
- Added database fields to store the schedule, duration and timezone of
maintenance window.
- Added helper classes to parse and calculate the maintenance window
schedule.
- Added exception handling classes to handle invalid maintenance window
schedule.

* Maintenance Window: Extended JSON model for REST APIs.
Extended the JSON model to support defining and communicating the
maintenance window information using the REST APIs.
- Additional JSON objects are defined to extend request and response
bodies.
- When requesting a distribution set assignment to a target, the
maintenance schedule information can be specified. Example below
specifies a maintenance schedule at 11:00 PM, only on Saturday, only in
2017, for 30 minutes. Maintenance window start time is then calculated
relative to the time zone specified, in this case CET summer time.
$ curl 'http://127.0.0.1:8080/rest/v1/targets/2/assignedDS' -i -X POST
-H 'Content-Type: application/json;charset=UTF-8' -d '{
"forcetime" : "0",
"id" : "1",
"type" : "forced",
"maintenanceWindow": {
"schedule": "0 0 23 ? * SAT 2017",
"duration": "00:30:00",
"timezone": "+02:00"
}
}'
- When device requests the action information it gets to know if there
is a 'maintenance schedule' for this action or not based on presence of
maintenanceWindow field in the response. The value of maintenanceWindow
is either 'available' (i.e. the maintenance window is now available as
per defined schedule and the update can progress) or 'unavailable'
(implying that maintenance window is not available now and update should
not be attempted). If there is no 'maintenance schedule' defined, the
field is null or not present.

* DDI API: Limit number of feedback messages for an action status.
Even though the number of ActionStatus entries are limited to 1000 per
action using QuotaManagement, there is no limit on the number of
messages that can be sent as part of a single ActionStatus. This allows
a controller to potentially send large number of messages for a single
action.
Limiting the number of allowed messages to 50 using the

* DDI API: Extend API response to retrieve controller feedback. (#381)
Resolves#381
The mechanism is useful for example, when the client software running on
the device loses this information prior to reporting a final execution
status such as 'closed' to hawkBit. This may happen, e.g., due to a
power cycle or simply a crash. Upon the client software restarting, it
installs the same payload again as advertised by hawkBit (as the device
has not sent a final update execution status). Instead, if the last
feedback sent to hawkBit would be reported back to the device, the
client may resume installation.
Feedback messages sent as part of POST
/{tenant}/controller/v1/{targetid}/deploymentBase/{actionId}/feedback,
are sent back to controller as part of response to GET
/{tenant}/controller/v1/{targetid}/deploymentBase/{actionId}.
Following example illustrates the API changes:
1. After retrieving the action from server, controller starts download
and sends a feedback.
curl
'http://127.0.0.1:8080/default/controller/v1/1/deploymentBase/1/feedback'
-i -X POST -H 'Content-Type: application/json;charset=UTF-8' -H 'Accept:
application/hal+json' -d '{
"id" : "1",
"time" : "20170406T121500",
"status" : {
"result" : {
"progress" : {
"of" : 1,
"cnt" : 0
},
"finished" : "none"
},
"execution" : "proceeding",
"details" : [ "proceeding with download" ]
}
}'
2. Once artifact download has finished, controller sends another
feedback.
curl
'http://127.0.0.1:8080/default/controller/v1/1/deploymentBase/1/feedback'
-i -X POST -H 'Content-Type: application/json;charset=UTF-8' -H 'Accept:
application/hal+json' -d '{
{
"id" : "1",
"time" : "20170406T123000",
"status" : {
"result" : {
"progress" : {
"of" : 1,
"cnt" : 0
},
"finished" : "none"
},
"execution" : "proceeding",
"details" : [ "downloaded artifacts for update" ]
}
}'
3. If there is a power outage now, the controller can retrieve the
messages posted earlier from the action history when it restarts again.
curl
'http://127.0.0.1:8080/default/controller/v1/1/deploymentBase/1?c=411599879&actionHistory=-1'
-i -H 'Accept: application/hal+json'
Response will be like below
{
"id": "1",
"deployment": {
"download": "forced",
"update": "forced",
"chunks": [
{
"part": "os",
"version": "1",
"name": "1",
"artifacts": [....],
}
],
},
"actionHistory": {
"status": "RETRIEVED",
"messages": [
"downloaded artifacts for update",
"proceeding with download"
]
}
}
4. Based on the feedback messages, controller may be able to skip the
download and resume with installation and send additional feedback.
curl
'http://127.0.0.1:8080/default/controller/v1/1/deploymentBase/1/feedback'
-i -X POST -H 'Content-Type: application/json;charset=UTF-8' -H 'Accept:
application/hal+json' -d '{
"id" : "1",
"time" : "20170406T121314",
"status" : {
"result" : {
"progress" : {
"of" : 1,
"cnt" : 0
},
"finished" : "none"
},
"execution" : "resumed",
"details" : [ "resuming installation based on previous feedback,
download skipped" ]
}
}'
Note: The maximum number of messages to be retrieved from the database
by a controller is limited to 100. The actionHistory parameter's value
has the following meaning:
Input Value | Output
-----------------------------
<0 | Retrieve maximum allowed number of messages from
| action history.
unspecified or =0 | Do not retrieve any message (default).
>0 | Retrieve specified number of messages, limited by
| maximum allowed number.
