Module checker 

Structs

Checker

Checker evaluates whether a transformed SQL still preserves the original failure.

PanicInfo 🔒

Information about a detected panic in component logs.

Functions

bootstrap_recovery 🔒

Execute bootstrap recovery command to fully restart RisingWave. This is needed when critical components (compute/meta/compactor) panic.

check_component_panic 🔒

Check if any critical component (compute/meta/compactor) has panicked recently. Only checks logs modified within the given time window to avoid false positives.

get_log_dir 🔒

Get the default RisingWave log directory path.

is_frontend_error 🔒

Check if the error message indicates a frontend-only error (SQL syntax, type mismatch, etc.) These errors are typically safe and can be handled by auto-recovery.

reconnect_frontend 🔒

Reconnect to the frontend PostgreSQL interface.

run_query

Executes a single SQL query string and returns (is_ok, error_message_if_any)

search_panic_in_log 🔒

Search for panic patterns in a log file. Uses tail to read only the last N lines for efficiency.

wait_for_auto_recovery 🔒

Wait for frontend to auto-recover with a timeout. Returns Ok if recovery succeeds, Err if timeout expires.

wait_for_recovery

Wait until RW recovery finishes (rw_recovery_status() = 'RUNNING')
