API 密钥有活跃请求时,在名称后显示蓝色并发气泡,方便在桌面端和移动端查看当前并发及允许并发。例如显示 ● 1/2;不限并发时显示 ● 1/∞,空闲时隐藏气泡。样式包含蓝色圆点,并适配深色模式。

管理页面每 5 秒读取一次当前进程中的并发快照,页面隐藏时暂停轮询,临时读取失败时保留上次快照。不限并发的密钥也会记录当前并发数,保留原有并发限制行为。

验证结果:

  • 前端 npm run typecheck:通过。
  • go test ./proxy ./admin -run 'APIKeyConcurrency' -count=1:通过(admin 包编译通过,无匹配测试)。
  • git diff --check upstream/main...HEAD:通过。

Summary by CodeRabbit

发布说明

  • 新增功能
    • API 密钥页面显示每个密钥当前处理的请求数及并发限制;未设置有效限制时显示 ∞。
    • 并发数据定期刷新;刷新失败时保留最近一次获取的数值。
  • 样式
    • 调整 Daybreak 徽章的圆角、内边距和文字大小。

依赖安全修复:

  • 单独提交将 npm 锁文件中的 source-map-js 从 1.2.1 升级至 1.2.2,修复 GHSA-68fv-2mgg-jv7q,并与 pnpm 锁文件版本保持一致。
  • 重新执行 npm ci 后,安全门禁 node scripts/audit-gate.mjs、npm run typecheck 和 npm run build 均通过。

📝 Walkthrough

Walkthrough

The proxy tracks inflight requests for valid API keys and exposes concurrency snapshots through an admin endpoint. The API keys page fetches snapshots and displays concurrency badges in mobile cards and desktop table rows. The Daybreak badge styling also changes.

Changes

API key concurrency visibility

Layer / File(s) Summary
Track and snapshot API-key concurrency
proxy/apikey_concurrency.go
HTTP and WebSocket acquisition track valid API keys with nonpositive limits. The proxy returns a locked snapshot of inflight counts.
Expose concurrency snapshots
admin/api_key_concurrency.go, admin/handler.go
The admin GET route returns the proxy snapshot as JSON.
Fetch and format concurrency data
frontend/src/api.ts, frontend/src/components/APIKeyConcurrencyBadge.tsx
The API client fetches the snapshot. A hook refreshes it every five seconds, skips overlapping and hidden-document refreshes, and retains the previous snapshot after a request fails. The badge shows a positive current count and a positive limit, or ∞ when the limit is missing or nonpositive.
Display counts on API keys
frontend/src/pages/APIKeys.tsx
Mobile cards and desktop table rows display a badge with each key’s current count and configured limit. Missing entries use a count of zero when snapshot data is available.

Daybreak badge styling

Layer / File(s) Summary
Adjust Daybreak badge styling
frontend/src/components/DaybreakBadge.tsx
The badge changes to medium corner rounding, narrower horizontal padding, and 11px text.

Merge Risk: ⚪ Minimal · up to 2b3de

No identified issue blocks merging, though the Daybreak badge change should receive normal visual validation.

Security Architecture Review

Security architecture risk: 🔵 Low · up to d7791

The new endpoint remains administrator-only, and existing concurrency admission controls are preserved. The main risk is accumulating historical counters for unlimited keys, increasing memory and monitoring overhead in a shared process. Complete background-job coverage and deployment-wide accuracy remain unestablished.

Retained concerns

  • Low · reliability · inferred: Tracking now retains counters for used unlimited keys as well as limited keys. Release and key deletion do not retire those entries, while each snapshot copies the historical map under the admission mutex. Long-running key churn can therefore increase memory and admission contention across keys sharing the handler. Retention predates this PR for positive-limit keys; its population and recurring read cost are expanded here. Arbitrary unauthenticated counter creation is not established.
Security review details

Security Blast Radius

  • inferred — The counter-growth concern affects the shared handler serving its tracked keys. A key holder can exercise an issued ID, but repeated use of that ID reuses one entry; expanding the retained population requires additional valid keys. The inspected creation route requires administrator authentication.

Trust Boundaries and Controls

  • observed — The snapshot route inherits existing admin authentication: an absent configured secret fails closed, and invalid credentials are rejected. Its response contains numeric key IDs and counts, not API-key credentials. Ordinary API-key authentication does not grant access to this route.

Resilience and Maintainability Implications

  • observed — Polling skips hidden pages and overlapping refreshes, preserves the previous snapshot on failures, and removes timers and listeners on cleanup. These sampled values drive display only; server admission continues to use atomic counters rather than the displayed snapshot.

Hardening Proposals

  • proposed — Consider bounded, race-safe retirement of deleted or long-idle key counters. Coordinate retirement with acquisitions rather than deleting entries immediately on release, because existing counter references can otherwise split admission accounting.

🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick win

Prune idle unlimited-key counters without racing acquisitions.

When an API key omits max_concurrency, its limit is zero. The first authenticated HTTP or WebSocket request now creates a counter for that key. Release only decrements the counter, and deleting the key does not remove it from the proxy’s limiter. The API Keys page polls a snapshot of every retained counter every five seconds, so key rotation makes the map, snapshot allocation, and response grow with historical keys. Remove idle counters with synchronization shared by acquisition; the existing test retains them to avoid orphan-counter races.

Update apiKeyConcurrencyLimiter.acquireTracked and the corresponding release
path to remove counters for unlimited keys once they reach zero, synchronizing
removal with acquisitions so a concurrent acquire cannot use an orphaned
counter. Adjust the retention behavior tested for idle counters to cover safe
pruning.
