Improve JSON parsing error messages with build-specific behavior:
- Debug builds: Show full parent object context and type mismatch details
- Release builds: Keep minimal snippets to avoid log spam
Add comprehensive test coverage for error handling and path parsing.
Add batch upsert functionality to reduce database round-trips from N to 1 when inserting courses. Create comprehensive database indexes for common query patterns including term/subject lookups, time-series metrics, and job scheduling. Remove redundant indexes and add monitoring guidance for BRIN index effectiveness.
Add retry tracking to scrape jobs with configurable max retries (default 5), implement
automatic database migrations on startup, and significantly reduce logging noise from
infrastructure layers. Enhanced tracing with structured spans for better debugging while
keeping output readable by suppressing verbose trace logs from rate limiters and session
management. Improved error handling with detailed retry context and proper session cookie
validation.
Add comprehensive ESLint setup with React and TypeScript support, create basic integration tests for the shutdown utilities, and enhance the Justfile with a new check command that runs all validation steps (cargo check, clippy, tests, and linting).
Implements graceful shutdown with broadcast channels and proper timeout handling
for scraper workers, scheduler, bot service, and status update tasks. Introduces
centralized shutdown utilities and improves service manager to handle parallel
shutdown with per-service timeouts instead of shared timeout budgets.
Key changes:
- Add utils module with shutdown helper functions
- Update ScraperService to return errors on shutdown failures
- Refactor scheduler with cancellable work tasks and 5s grace period
- Extract worker shutdown logic into helper methods for clarity
- Add broadcast channel shutdown support to BotService and status task
- Improve ServiceManager to shutdown services in parallel with individual timeouts
Replace task abortion with broadcast-based graceful shutdown for scheduler and workers. Implement cancellation tokens for in-progress work with 5s timeout. Add tokio-util dependency for CancellationToken support. Update ServiceManager to use completion channels and abort handles for better service lifecycle control.
