AI Summary
A critical bug fix for the SpacetimeDB scheduler where scheduled functions were drifting due to incorrect time anchoring.
Key Highlights
- Fixed scheduled function drift by anchoring to intended execution time
- Adopted 'MissedTickBehaviour::Skip' semantics to prevent future drift
- Resolved issue where head-of-line blocking caused permanent schedule delays
New Features
- Scheduler time anchoring fix
Full Release Notes
## Bug Fixes ### Fix scheduled function drift Scheduled functions were previously rescheduled from the actual execution time of the current run instead of the originally intended time. A small `tokio::time` precision delay, or head-of-line blocking from a prior run, would cause the schedule to permanently drift later over time. The scheduler now anchors to the intended execution time, adopting `MissedTickBehaviour::Skip`-like semantics. ([#5735](<https://github.com/clockworklabs/SpacetimeDB/pull/5735>)) ## What's Changed - Bug: Scheduled functions to be scheduled from their "intended" execution time in [#5735](<https://github.com/clockworklabs/SpacetimeDB/pull/5735>) **Full Changelog**: [v2.8.2...v2.8.3](<https://github.com/clockworklabs/SpacetimeDB/compare/v2.8.2...release/candidate/v2.8.3>)
