Description

• Migrated the metrics service to use the new version of fibers
• Metrics now has annotations for functions and types
• Logic and state is now separate from pipelines to reduce pipeline cloning
• Metrics configs are now done via metric name rather than endpoint, cutting down on pipeline reuse
• Changed bus API to fit new runtime proposal
• Added test utils
• • Fibers clock can now be manually moved forwards instead of sleeping for time dependent tests
• • A time harness uses ticks (instances of a yield) as a timeout instead of actual time, this removes system specific failures due to timeout being missed and makes time based tests deterministic
• I have tests for cases where manual testing is either not possible or would take more time than just making the tests (verifying filter logic for example)

Manual test

• 👍 yes

Manual test description

Add the correct cloud url into the config.json
Comment line 481 and un-comment line 482 to make sure the metrics service does not lock due to missing time service
Run new devicecode with
DEVICECODE_CONFIG_DIR=./configs/ DEVICECODE_SERVICES=config,hal,gsm,metrics luajit main.lua
Check grafana for metrics being sent up
