v0.1.0-beta.2

🚀 Features

• Update README: Describe the update and release cycle, describe how to run the code on the RasPi, add information about used Raspi OS
• On upgrades, wait to finish the message-sending before upgrading: #81
• Add restart command: #80
• Simplify and use calibration procedure: We implemented it before but never used it. Now it is run daily and works great: #71
• Send heartbeats: Heartbeats are now sent on success/failure of a config update and every 5 minutes: #67, #29
• Communicate with new air inlet sensor: Now using the SHT45 and BME280 instead of the SHT21 only: #61
• Copy state.json file on upgrades

🔧 Refactoring

• Simplify Config: Make calibration config simpler, rename properties
• Improve validation: Use pydantic.Field() instead of custom validator functions (8dc0710). I didn't know about this feature before because the Pydantic docs are hard to read. This style of validating fields is not found under "validators" and is hard to find using DuckDuckGo/Google; you must go to schema to find anything about this method. My old way is how they recommended in the "validators" section, but they do not advertise this pydantic.Field() method even though the notation is so much cleaner and can do the same in ~95% of use cases.
• Class Renaming: MessagingAgent -> MQTTAgent, ActiveMQTTQueue -> MessageQueue
• Improve CLI functionality: Now the hermes-cli kills the process with SIGTERM and force-kills it if it has not terminated on its own after 10 seconds.
• Simplify MQTT messaging: Messages will now be written to the archive on arrival instead of after a successful send. With this, we could remove the entire archiving mechanism
• Simplify Logging: Now the messages will be written to the archive directly instead of keeping the last hour of logs in a current-logs.log file

🐛 Bugfixes

• Debug teardown procedure: In the teardown function of the main thread and the communication loop, the graceful teardown was sometimes observed to take very long. It was probably one of the reasons for the scaling issues I observed. I added a timeout to this graceful teardown, so the process will be terminated immediately if the graceful teardown takes more than 10 seconds: #70, #60.
• Fix wrong valve specification: #62
• Fix bug in tests where both local and utc time were used: I was lucky to spot this one because I ran the messaging tests while the local time was on a different date than the utc time: code wrote into 2023-05-24, test were expecting 2023-05-23. Now everything is using local time for filenames.

v0.1.0-beta.1

⚠️ This is the release for the master's thesis of Moritz Makowski ⚠️

🚀 Features

• Implement integration tests for all hardware interfaces: #19
• Raise TimeoutError when setup takes too long: #57
• Raise TimeoutError when mainloop iteration takes too long: #54
• Reboot when an error persists for more than 12 hours: #56
• Add repairing routing for communication threads: #49
• Test cutting of very long log messages: Subjects will be cut to 256 characters and details to 16384 characters. In case the message gets cut, the last few characters indicate how much has been cut: " ... CUT (20249 -> 16384)"
