openclaw - 💡(How to fix) Fix [Bug]: Plugin metadata hot paths repeat installed manifest filesystem probes [5 pull requests]

Bug type

Behavior bug (incorrect output/state without crash)

Beta release blocker

No

Summary

Gateway plugin metadata hot paths repeatedly resolve and stat stable installed manifest/package metadata when fingerprinting the same installed plugin index object.

Steps to reproduce

1. Run a long-lived OpenClaw gateway workload with active session, subagent, and plugin metadata traffic.
2. Capture a CPU profile and diagnostics timeline.
3. Inspect the profile/timeline for the call chain described in the evidence below.

Expected behavior

Repeated fingerprint requests for the same process-local InstalledPluginIndex object should reuse the computed fingerprint and avoid restatting manifest/package files.

Actual behavior

Profile evidence showed lstat/realpathSync/stat chains under resolveInstalledManifestRegistryIndexFingerprint, buildInstalledManifestRegistryIndexKey, resolvePackageJsonPath, and plugin metadata snapshot lookup.

OpenClaw version

Current main source checkout before the linked fix branch; exact release build is NOT_ENOUGH_INFO.

Operating system

Install method

Source checkout / development workflow.

Model

Provider / routing chain

Additional provider/model setup details

Not model-specific; this is a gateway/session/plugin hot-path performance issue.

Logs, screenshots, and evidence

Profile snippets showed lstat and realpathSync under resolvePackageJsonPath -> buildInstalledManifestRegistryIndexKey -> resolveInstalledManifestRegistryIndexFingerprint -> resolvePluginControlPlaneContext -> getCurrentPluginMetadataSnapshot.

Impact and severity

Affected: plugin discovery/manifest registry and gateway plugin metadata control-plane lookups. Severity: Medium. Frequency: repeated hot metadata calls in the captured profile. Consequence: avoidable synchronous filesystem probes on stable process metadata.
