fix(supervisor): auto-recover deploying stuck state when deploy completes #948
Conversation
…etes Add recover_stuck_deploying() function that checks deploy logs for completion markers and transitions tasks from deploying to deployed. Includes test coverage for the state machine recovery path. Refs: t222
Summary of ChangesHello @marcusquinn, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces a critical reliability improvement to the supervisor system by implementing an auto-recovery mechanism for tasks that become stuck in the 'deploying' state. This ensures that even if a deployment succeeds but the subsequent state transition or related housekeeping operations fail, the system can automatically correct the task's status, preventing tasks from being orphaned and requiring manual intervention.

Code Review
This pull request introduces a robust auto-recovery mechanism for tasks that get stuck in the deploying state. The changes in supervisor-helper.sh add logic to both cmd_pr_lifecycle and cmd_pulse to detect and recover these tasks, with comprehensive tests added in test-supervisor-state-machine.sh. My review focuses on adherence to the shell scripting style guide and the correctness of the recovery logic. I've identified a few areas for improvement: two instances of stderr suppression that violate the style guide, and a potentially risky fallback in the recovery logic that should be adjusted for safety.

The fallback logic here seems incorrect. If cmd_pr_lifecycle fails, it indicates a more severe problem than a simple transition failure (which is already handled inside cmd_pr_lifecycle by transitioning to failed). Forcing the task to deployed in this case is risky, as the deployment state is unknown and the task might not be deployed at all. A safer fallback would be to transition the task to failed to signal that manual intervention is required.

Error suppression with 2>/dev/null violates the repository style guide. Rule #50 states that 2>/dev/null is only acceptable when redirecting to log files, not for blanket suppression. Errors from write_proof_log should be captured for debugging purposes.

Error suppression with 2>/dev/null violates the repository style guide. Rule #50 states that 2>/dev/null is only acceptable for redirecting to log files, not for blanket suppression. If the database query fails for reasons other than returning no results (e.g., locked database, syntax error), the error will be silently ignored. It's safer to redirect stderr to the supervisor log.

Avoid failing tasks when recovery races with a concurrent transition.
Line 7244: If cmd_transition fails because another process already moved the task out of deploying, this block marks the task failed, which corrupts state. Re-check the current status and only fail if it’s still deploying.

Guard the force-deploy fallback with a state re-check.
Line 7840: The fallback forces deployed on any cmd_pr_lifecycle error. If the task was transitioned to failed/blocked/cancelled between the query and recovery, this overwrites the real outcome. Re-read current status and only force when still deploying.
