All notable changes to this project will be documented in this file. This project adheres to Semantic Versioning.

[1.4.0]

### Added * Attribute on sdpleafnode named assignResourcesSchemaVersion which sets default version of SDP assign resources schema if not set.

### Updated * TMC Mid supports new TMC AssignResources json v2.2 with SDP v1.0.

### Fixed * Hardcoding of sdpleafnode is now removed and attribute is created to make it runtime configurable.This resolves SKB-927.

[1.3.0-rc.1]

### Added

  • TMC-Mid considers weather parameters while calculating the delay model

  • Validate SKB-932

  • Utilised centralnode v0.19.7 to validate SKB-860.

  • Utilised dishleafnode v0.23.1 with updated Abort command completion check.

[1.2.0-rc.5]

### Updated

  • Utilised latest version of centralnode v0.19.7 to resolve SKB-860

  • Utilised latest version of dishleafnode v0.23.1 to updated Abort command completion check.

[1.2.0-rc.4]

### Fixed

  • Updated version of weather station to resolve Bug SKB-932 : Operator not setting to true while utilising Weather Station device.

[1.2.0-rc.3]

### Added

  • Weather Station Device integrated which provides weather data for delay correction calculations.

  • Updated SDP leafnode tag to 0.22.3

[1.2.0-rc.2]

### Added

  • Implemented timeout and exception propagation for Abort and Restart commands

[1.2.0-rc.1]

### Added

  • TMC uses wrap sector to generate program track table

  • TMC performs track table generation based on Fixed Trajectory data

  • Partial Configure now supports updating individual configuration keys. The Dish Leaf Node applies changes only to the specified fields.

[1.1.0]

### Added

  • Event Handlers are updated to remove event processing logic and handle it under component manager.

  • Updated Central node command execution logic for Dishes to send ON/OFF/STANDBY

    commands even if it fails for one dish , command will still be sent to other dishes.

  • Utilized refactored event manager in ska-tmc-centralnode version 0.19.5

  • ska-tmc-common version 0.27.5 is utilized for the same

### Fixed
  • As a part of SKB-517 resolution pointingState SLEW was accepted as valid Dish

    pointingState , so that TMC subarry can move to READY obsState. But it was found that sometimes TRACK event for the dish which used to come to TMC after it moves to READY was causing issues in obsState aggregation. Hence, going forward TRACK event will not be sent from Dish Leaf Node if command is not in progress.

Read the Docs warnings addressed

[0.22.1]

Observation State Aggregation Logic improvements

  • Rule engine is used to define rules for ObsState

  • EventDataStorage class introduced to store event related data

[0.22.0]

  • Utilised base class v1.0.0 and pytango 9.5.0 on TMC nodes*

    • Utilised ska-tmc-common v0.17.6 for tango helper devices.

    • Implemented queue according to support base classes v1.0.0.

    • Refactored command allowed method to put commands in queue.

    • Implemented command allowed methods for observation-specific commands to allow/reject the queued task: ResultCode.NOT_ALLOWED/ResultCode.REJECTED.

    • Refactored error propagation implementation on SubarrayNode, CentralNode, and TMC leaf nodes to handle longrunningcommandresult attribute new format in case of raised exceptions.

    • Refactored error propagation implementation to handle longrunningcommandresult event for ResultCode.NOT_ALLOWED, ResultCode.REJECTED, and ResultCode.FAILED.

    • Refactored all the integration tests (pairwise and with mocks) for TMC Mid according to longrunningcommandresult attribute value.

  • Utilised cspsubarrayleafnode v0.19.1 with fixed SKB-413: Mid Delay Model code pointing to wrong dishes.

    • Implemented antenna parameters objects to generate according to mid_json layout.

    • Corrected Mid Delay Model to point to SKA or MKT dish according to assigned receptors.

  • Utilised dishleafnode v0.16.3 Patch release for SKB-419 fix from branch SAH-1566.

[0.21.2]

  • Fix image link reference for DishLeafNode.

[0.21.1]

  • Resolve SKB-419.

  • Resolve SKB-384 - Currently, across all devices in TMC, there are no polled attributes (after our work on SKB-384). TMC monitors the attributes of other devices using event subscription methods. Unlike polling, which involves continuous querying, event subscription relies on a push-based mechanism. When a device generates an event (such as an attribute value change), the Tango system notifies all subscribed clients. As a result, there is no ongoing polling loop; TMC only receives updates when events occur.”
