Pad ethereum address with zero to fix transfer monitoring; fix operator monitoring re-assignment

[chrisli30]

This pull request introduces significant changes to improve task management, logging, and operator connection handling in the core/taskengine package, as well as updates to the cmd/status.go file for enhanced system status reporting. Key themes include enhanced logging for debugging, improved operator lifecycle management, and better handling of orphaned tasks.

Enhanced Logging for Debugging

• core/taskengine/engine.go: Added detailed logs for task creation, including node and edge breakdowns, as well as final counts for successful creation. Logs now include connection stability checks and task assignment details during operator reconnections. [1] [2] [3] [4]

Operator Lifecycle Management

• core/taskengine/engine.go: Introduced ticker context and cancellation mechanisms to manage operator lifecycle more effectively, ensuring proper cleanup during disconnections and reconnections. Added safeguards to prevent race conditions during operator reconnections. [1] [2] [3]

Handling Orphaned Tasks

• core/taskengine/engine.go: Improved orphaned task reassignment logic, ensuring tasks are reclaimed when operators reconnect. Added aggregated logging for reassigned tasks and introduced checks for active operators before reassignment. [1] [2]

System Status Reporting

• cmd/status.go: Overhauled the status command to display detailed system status, including active tasks in the database, troubleshooting tips, and database initialization checks.

Testing Utilities

• core/taskengine/engine.go: Added AddTaskForTesting method to facilitate direct task injection into the engine for testing purposes, bypassing database storage and validation.

Pull Request Overview

This PR enhances operator reconnection and task assignment robustness, adds comprehensive integration tests, and improves system status reporting and REST processing.

• Implements context-based ticker management and ensures task tracking resets on any reconnection
• Adds integration tests for ticker context races, operator reconnection flows, orphaned task reclamation, and monotonic clock behaviors
• Introduces a new status CLI command and updates REST and event-trigger components for JSON-aware processing and Ethereum address padding

cmd/status.go:25

• The new status command lacks automated tests. Add unit or integration tests to validate output formatting and error conditions (e.g., no DB, empty tasks).
