Root Cause:
When a console proxy record expired, the backend removed only the database VO and immediately established a new proxy. For DPU VNC, the old proxy session remained on the agent and conflicted with the recreated session.

Solution:
Delete the existing console session through the backend before establishing a replacement. Propagate deletion failures instead of creating another proxy on an uncleared agent session.

Test:
Added an integration case that expires a console proxy record and verifies the old proxy is deleted before a new one is established.

Verified with:
mvn package -pl console -am -DskipTests -Djacoco.skip=true

The full ./runMavenProfile premium build was attempted but did not complete because of the local build environment.

Resolves: ZSTAC-87566

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance.

Walkthrough

本次变更新增独占控制台会话续租能力。过期代理根据虚拟化后端要求选择续租路径,并调整令牌生成、会话删除失败处理及集成测试覆盖。

新增传统续租和独占续租测试,覆盖代理重建、令牌更新、删除失败及重试行为。

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: ⚪ Minimal · up to 013d1

The change deletes an expired console proxy before recreating it and propagates deletion failures; no actionable merge-blocking risk remains beyond normal checks and review.

兔子敲键盘,代理焕新光
会话先清理,令牌添新章
失败留记录,重试不慌张
两种续租路,测试护航

consoleMgr 重命名为 consoleManager

consoleMgr 使用了不必要的缩写。使用完整名称可使受保护字段和续租逻辑更清晰。

根据路径指令:“不允许使用不必要的缩写……应使用完整单词提升可读性”。

建议修改
-    protected ConsoleManager consoleMgr;
+    protected ConsoleManager consoleManager;
...
-            ConsoleHypervisorBackend backend = consoleMgr.getHypervisorConsoleBackend(HypervisorType.valueOf(vm.getHypervisorType()));
+            ConsoleHypervisorBackend backend = consoleManager.getHypervisorConsoleBackend(HypervisorType.valueOf(vm.getHypervisorType()));

用具名策略替代 removeVoOnFailure 布尔参数。

truefalse 表示不同的数据库删除策略。调用点无法直接表达业务意图。使用枚举或两个具名私有方法表达“删除失败后移除记录”和“删除失败后保留记录”。

根据路径指令:“避免使用布尔型参数造成含义不明确”。

Root Cause:
DPU baremetal VNC uses a single-client x11vnc session. When its console token expired, the shared renewal flow removed only the proxy VO and established a new token without deleting the old proxy connection. The stale connection continued occupying the VNC session, causing the newly opened console to remain black.

Solution:
Let a hypervisor console backend identify sessions that require exclusive renewal and generate a unique token for each such session. Keep the original shared-session renewal behavior for KVM and other backends. For an expired exclusive session, reuse the existing console recreation flow to delete the old proxy connection before establishing the replacement.

Test:
Update console integration coverage to verify that shared renewal keeps its original behavior and exclusive renewal deletes the old proxy before creating a different token. The case was not rerun after the final simplification as requested.

Verified with:
git diff --check
