调研方向

阅读 pkg/workflow/safe_update_enforcement.go 和 pkg/workflow/safe_update_manifest.go，然后追踪调用方 extractPullRequestEventPresenceFromCompiledWorkflow。合并重复的事件检测，并更新调用方以使用共享实现。运行 make fmt 和 make test-unit；只有 safe-update 强制执行和清单检测都仍然通过，才算完成。

🔍 Duplicate Code Detected: Duplicate pull_request event detection

Analysis of commit 8c2337a

Assignee: @copilot

Summary

extractPullRequestEventPresenceFromOnField and detectPullRequestEvents have byte-for-byte identical bodies (21 normalized lines). Both parse a workflow on: field into (hasPR, hasPRTarget) and both live in the workflow package.

Duplication Details
Pattern: on: field → (pull_request, pull_request_target) presence
  • Severity: Medium
  • Occurrences: 2
  • Locations:
    • pkg/workflow/safe_update_enforcement.go (lines 131-153, extractPullRequestEventPresenceFromOnField)
    • pkg/workflow/safe_update_manifest.go (lines 182-207, detectPullRequestEvents)
  • Code Sample: 
    func detectPullRequestEvents(onField any) (hasPR bool, hasPRTarget bool) {
    switch v := onField.(type) {
    case string:
        return v == "pull_request", v == "pull_request_target"
    case []any:
        for _, item := range v {
            event, ok := item.(string)
            if !ok { continue }
            if event == "pull_request" { hasPR = true }
            if event == "pull_request_target" { hasPRTarget = true }
        }
    case map[string]any:
        _, hasPR = v["pull_request"]
        _, hasPRTarget = v["pull_request_target"]
    }
    return hasPR, hasPRTarget
}
Impact Analysis
  • Maintainability: Event-parsing changes must be mirrored across two files.
  • Bug Risk: The two copies can diverge, causing inconsistent safe-update enforcement vs manifest detection.
  • Code Bloat: ~23 duplicated lines across two files in the same package.
Refactoring Recommendations
  1. Extract a single shared helper
    • Keep one function (e.g. detectPullRequestEvents) and have extractPullRequestEventPresenceFromOnField delegate to it, or remove the duplicate and update the one caller (extractPullRequestEventPresenceFromCompiledWorkflow).
    • Estimated effort: ~15 min, low complexity.
    • Benefits: single source of truth for on: event detection.
Implementation Checklist
  • Collapse to one implementation and update callers
  • Run make fmt and make test-unit
  • Verify safe-update enforcement and manifest detection unaffected
Analysis Metadata
  • Analyzed Area: pkg/ non-test .go files
  • Detection Method: normalized function-body hashing + manual verification
  • Commit: 8c2337a
