Fix #1873: fix: openclaw doctor reports DuplicateOpenClawRuntimeError (false positive)

[Memtensor-AI]

Description

Summary

Successfully fixed the false positive DuplicateOpenClawRuntimeError reported by openclaw doctor when the OpenClaw gateway is running with memos-local-plugin.

Root Cause

The runtime lock mechanism in apps/memos-local-plugin/adapters/openclaw/runtime-lock.ts was designed to prevent duplicate OpenClaw gateway instances from running simultaneously. However, it didn't distinguish between:

• A legitimate duplicate gateway runtime (should be blocked)
• The openclaw doctor diagnostic process (should be allowed)

When openclaw doctor tried to load the plugin while the gateway was running, it attempted to acquire the same runtime lock and was blocked with a false positive error.

Solution Implemented

Added diagnostic mode detection that allows read-only processes like openclaw doctor to skip runtime lock acquisition:

1. Runtime Lock Enhancement: Added skipLock?: boolean parameter to AcquireOpenClawRuntimeLockOptions. When true, acquireOpenClawRuntimeLock() returns a no-op lock handle that doesn't create lock files or block.

2. Diagnostic Mode Detection: Added isDiagnosticMode() helper function that detects diagnostic processes via:

   • OPENCLAW_DIAGNOSTIC_MODE environment variable (set to "1" or "true")
   • Process title containing "doctor"
   • Process argv containing "doctor"

3. Plugin Registration Update: Modified the register() function to detect diagnostic mode and pass skipLock: true to lock acquisition, with appropriate logging.

Changes Made

Modified Files:

• apps/memos-local-plugin/adapters/openclaw/runtime-lock.ts: Added skipLock parameter and no-op lock handling
• apps/memos-local-plugin/adapters/openclaw/index.ts: Added diagnostic mode detection and integration
• apps/memos-local-plugin/tests/unit/adapters/openclaw-runtime-lock.test.ts: Added unit tests for skipLock behavior
• apps/memos-local-plugin/tests/integration/diagnostic-mode.test.ts: New integration test verifying doctor can run alongside gateway

Test Coverage:

• Unit tests verify that skipLock returns no-op lock handles
• Integration tests confirm doctor process can run while gateway holds lock
• Existing tests ensure normal gateway lock behavior is unchanged

Verification

The fix is backward compatible and maintains all existing security properties:

• Normal gateway instances still block duplicate runtimes
• Diagnostic mode only activates when explicitly detected
• No lock files are created in diagnostic mode
• Gateway lock cleanup remains unchanged

Usage

Users can now run openclaw doctor while the gateway is active. The diagnostic process will automatically detect it's running in diagnostic mode and skip lock acquisition. Alternatively, users can explicitly set OPENCLAW_DIAGNOSTIC_MODE=1 to force diagnostic mode.
