v5.14.0

OpenC3 COSMOS 5.14.0 - Related Telemetry, Cmd/Response Framework, Dynamic Packet Definition, and More

Welcome to OpenC3 COSMOS 5.14.0!

Related Telemetry Items and Screens for Commands

Commands have a new keyword for associating related telemetry items to the command: RELATED_ITEM. This automatically builds a telemetry screen that is shown alongside the command in CmdSender. If you want to get fancy, you can also associate a full custom built telemetry screen with the SCREEN keyword.

Generic Command / Response Protocol

The command response architecture is a command pattern for a lot of different devices, so we took the legacy TEMPLATED protocol and extracted the command response pattern from it into its own CmdResponseProtocol class. Adding this protocol to your Interface will put it into a command/response mode for any commands that have an associated RESPONSE keyword defined.

Dynamic Packet Definition

We've added the ability to dynamically define packets within the COSMOS framework at runtime. This will typically be done by an Accessor or a Processor after receipt of a packet to define its contents for access by our fronted tools.

BucketExplorer Folder Size

BucketExplorer now calculates and displays the size of all files in the currently displayed folder.

New ping endpoints for our API containers

We added a couple new ping endpoints to our API containers that can be used for health/aliveness checks.

PROCESSORs now only run in the Decom microservice

Previous processors were being run both in the interface and in decom (twice total). Processors can now be used reliably run once on each packet reception, so they can safely perform side effects if needed. This is a potentially breaking change if the multiple execution was expected in previous versions.

ScriptRunner Performance Greatly Enhanced

ScriptRunner was updated to process script events in batches, rather than one at a time. This greatly improved ScriptRunner performance and should keep it from ever falling behind when flying through lots of lines that would have to be highlighted one by one.

Important Bug Fixes

1. Accessors now enforce data type on read/write
2. wait() fixed in Python scripts
3. Continue even if there are errors in local_init in the init container. This removes many use cases where the init container can get stuck looping, and will allow for manual recovery by users.
4. Fixed diff logic on plugin upgrade
5. Fixed Python Tcp/IP Client Interface
6. Made tlm item cache default to no caching, unless you specifically want it
7. Fixed a bug where Interface#disconnect would not be called if an exception was raised during Interface#connect
8. Fixed BucketExplorer routes with special characters
9. Fixed writing Python strings without first converting them to bytes type
10. Fixed loading TlmGrapher configurations with more than one graph specified
11. Support upload/download from TableManager in Python
12. Fixed a bug with the rux-status component handling of fatal
13. Updated DataExtractor to handle receiving null values

Prerequisites:
Docker - Running OpenC3 requires a working Docker or Podman installation. Typically Docker Desktop on Windows / Mac. Plain Docker or Podman also works on linux. We actively develop and run with Docker Desktop on Mac/Windows, and Linux on Raspberry Pi, so if you have any issues on another platform, please let us know by submitting a ticket!

Minimum Resources allocated to Docker: 4GB RAM, 1 CPU, 80GB Disk
Recommended Resources allocated to Docker: 16GB RAM, 2+ CPUs, 100GB Disk
Also requires docker compose version 1.27+

To Run:

• git clone https://github.com/openc3/cosmos-project.git cosmos-myproject
• cd cosmos-myproject
• Run Linux/Mac: ./openc3.sh run
• Run Windows: openc3.bat run
• Connect a web browser to http://localhost:2900/
• Have fun running OpenC3 COSMOS!
