Fixes GFX-1078
Closes #706

Summary by CodeRabbit

  • 性能优化
    • 不同玩家的在线会话刷新和恢复可并行处理,减少彼此等待。
    • 同一玩家的相关会话操作仍按顺序执行,避免并发操作相互冲突。
  • 可靠性改进
    • 使用同一令牌同时发起多次会话恢复时,仅一次能够成功,其他请求会被识别为令牌已失效。

Explanation

[#706] 已将 OnlineSessionReconnectService 的全局恢复门改为 64 个分片门。ResumeAsync 按 Token 选择分片,因此同一 Token 的验证、连接替换和轮换仍互斥,不同分片的 Token 可以并行。OnlineSessionTokenService 也将轮换等变更按 (TenantId, AppId, PlayerId) 分片,避免恢复内部的 Token 轮换再次形成全局队列。测试覆盖同一 Token 并发时恰好一次成功,以及不同玩家恢复和刷新在另一玩家写入阻塞时仍可完成。

让同一 Token 的恢复请求实际重叠,并断言只有获准的恢复进入标记步骤。

默认测试基座使用 InMemoryOnlineSessionStore,其写入和事件发布都返回已完成任务。Task.WhenAll 依次求值三个 ResumeAsync 调用,每次调用完成后才开始下一次。因此测试不会产生重叠,移除恢复门后仍可能通过。

仅阻塞写入还不够。令牌轮换门和门内复验仍保证恰有一次成功,所以 Assert.Equal(1, successes) 无法检测恢复门被移除。

移除恢复门后,阻塞期间的第二次和第三次调用仍会通过旧令牌的验证,并进入 MarkResumedAsync。这两次调用在存储写入后都会发布 SessionConnected 事件。有恢复门时,它们在门内等待。令牌轮换后,它们的验证失败,不会到达标记步骤。因此事件增量应恰好为 1。

在分片门内按会话 ID 重新读取会话,并检查是否已终态。

SweepExpiredAsync 在取门前用 ListNonTerminalAsync 生成快照。内存存储返回的是同一会话对象的引用。KickAsync 或 RevokeAsync 可在清理等待分片门期间关闭该会话。门内只检查快照的 TokenExpiresAtTime。关闭操作不改变到期时间,因此清理仍会调用 CloseSessionAsync。结果是已踢下线或已吊销的会话被改为 Expired,并发布一条错误的过期事件。

建议门内重新读取会话,并检查终态与到期时间。

确保测试使用不同的恢复分片。

两个随机 Token 可能选中同一个恢复分片。发生碰撞时,otherResume 必须等待尚未放行的首个写入,五秒断言就会在正确实现上失败。布防前请选择恢复分片不同的两个 Token,避免并行测试随机失败。(raw.githubusercontent.com)
