The config IO system (src/config/io.ts) contains multiple catch blocks that silently swallow errors without proper logging or error recovery. This makes debugging configuration issues extremely difficult, as failures in config writes, health state updates, and audit logging are completely invisible to operators.

PR fix notes

PR #61522: config/io: add proper logging for IO error handling

Description (problem / solution / changelog)

Summary

  • Problem: Config IO catches errors with empty catch blocks, making it impossible to debug configuration issues (disk full, permission denied, locked files)
  • Why it matters: Operators cannot see why config operations fail; silent data loss scenarios go undetected
  • What changed: Created error classification utility and added proper logging to 17+ catch blocks in io.ts and 6 in backup-rotation.ts
  • What did NOT change: Core config IO behavior - maintains "best-effort" semantics while making errors visible

Root Cause (if applicable)

  • Root cause: Empty catch blocks with // best-effort comments silently swallow all IO errors
  • Missing detection / guardrail: No logging for config IO errors
  • Contributing context (if known): N/A

Regression Test Plan (if applicable)

  • Coverage level that should have caught this:
    • Unit test
    • Seam / integration test
    • End-to-end test
    • Existing coverage already sufficient
  • Target test or file: N/A
  • Scenario the test should lock in: N/A
  • Why this is the smallest reliable guardrail: This is a logging enhancement that maintains existing behavior
  • Existing test that already covers this (if any): N/A
  • If no new test is added, why not: This is a logging-only change - no behavior modification

User-visible / Behavior Changes

  • Logs now appear for config IO errors (debug/warn/error level based on error type)

PR #61609: fix: add error logging to empty catch blocks in Config IO

Description (problem / solution / changelog)

Fixes #61520

Summary

Replace 9 empty catch blocks in src/config/io.ts with proper error logging so that failures in config operations are visible to operators instead of silently swallowed.

Changes

Each empty catch block now logs the error at an appropriate level while preserving the existing best-effort behavior:

LocationOperationLogger used
appendConfigAuditRecordAudit log async writedeps.logger.warn
appendConfigAuditRecordSyncAudit log sync writedeps.logger.warn
writeConfigHealthStateHealth state async writedeps.logger.warn
writeConfigHealthStateSyncHealth state sync writedeps.logger.warn
Async backup restoreCopy backup to config pathparams.deps.logger.warn
Sync backup restoreCopy backup to config path (sync)params.deps.logger.warn
Config write env-restoreRead current config for env refsdeps.logger.warn
Permission hardeningchmod on state dirconsole.error (no deps)
Write listener notificationObserver callback errorsconsole.error (no deps)

Design decisions

  • Used warn level (not error) for most cases since these are best-effort operations and the system continues to function
  • Preserved all existing comments explaining why the catch exists
  • Used console.error with OPENCLAW_DEBUG guard for permission hardening (no logger deps available in that scope)
  • Used console.error for write listener errors (no logger available in that scope)
  • Error messages include the file path and the error message for easy debugging

Changed files

PR #61874: fix: add error logging to empty catch blocks in Config IO

Description (problem / solution / changelog)

Fixes #61520

Summary

Replace 9 empty catch blocks in src/config/io.ts with proper error logging so that failures in config operations are visible to operators instead of silently swallowed.

Changes

  • Each empty catch block now logs the error with deps.logger.warn() or console.error()
  • All logging calls are guarded by OPENCLAW_DEBUG to avoid noisy output in production
  • Error objects are passed directly to preserve stack traces

Changed files

  • src/config/io.ts (modified, +18/-13)

Summary

The config IO system (src/config/io.ts) contains multiple catch blocks that silently swallow errors without proper logging or error recovery. This makes debugging configuration issues extremely difficult, as failures in config writes, health state updates, and audit logging are completely invisible to operators.

Problem to solve

Errors in critical operations like config writes, health state persistence, and audit logging are caught with empty catch blocks:

// Line 729-731 in io.ts
} catch {
  // best-effort
}

This pattern appears in 17+ locations across io.ts alone, making it impossible to distinguish between "file doesn't exist" (acceptable) and "permission denied" or "disk full" (critical).

Proposed solution

  1. Create a utility function that classifies IO errors by type (not found, permission, disk full, unknown)
  2. Add level-aware logging: debug for "not found", warn for "permission denied", error for "disk full"
  3. Add optional retry logic for transient failures (disk I/O, locking conflicts)
  4. Consider adding a strictIoErrors config flag to make IO errors fatal in production

Alternatives considered

  • Keep empty catch blocks: Makes debugging impossible, operators cannot see why config operations fail
  • Throw all errors: Would break "best-effort" behavior that existing code expects, causing unnecessary failures

Impact

  • Affected users/systems/channels: All OpenClaw installations using config IO
  • Severity: Medium to High
  • Frequency: Intermittent (occurs when disk is full, permissions are wrong, or files are locked)
  • Consequence: Silent data loss scenarios, inability to debug configuration issues, no alerting on configuration system health

Evidence/examples

No response

Additional information

  • This improves debuggability of configuration issues by 10x
  • Prevents silent data loss scenarios (disk full during config write)
  • Enables proactive alerting on configuration system health

extent analysis

TL;DR

Implement a utility function to classify and log IO errors with level-aware logging and consider adding retry logic for transient failures.

Guidance

  • Identify and replace empty catch blocks in io.ts with the proposed utility function to classify IO errors.
  • Implement level-aware logging to distinguish between different types of errors, such as "not found", "permission denied", and "disk full".
  • Consider adding optional retry logic for transient failures, such as disk I/O or locking conflicts.
  • Evaluate the need for a strictIoErrors config flag to make IO errors fatal in production environments.

Example

// Example utility function to classify and log IO errors
function logIoError(error: Error) {
  if (error.code === 'ENOENT') {
    // Log debug for "not found" errors
    console.debug('File not found:', error);
  } else if (error.code === 'EACCES') {
    // Log warn for "permission denied" errors
    console.warn('Permission denied:', error);
  } else if (error.code === 'EDQUOT') {
    // Log error for "disk full" errors
    console.error('Disk full:', error);
  } else {
    // Log unknown errors
    console.error('Unknown IO error:', error);
  }
}

Notes

The proposed solution aims to improve debuggability and prevent silent data loss scenarios. However, the implementation details may vary depending on the specific requirements and constraints of the OpenClaw system.

Recommendation

Apply the proposed solution to implement a utility function for classifying and logging IO errors, and consider adding retry logic for transient failures. This approach balances the need for debuggability and error handling with the existing "best-effort" behavior of the config IO system.
