Тест StreamEvent на свободном порту, время по второму запросу

[sfaqer]

ТестДолженПроверитьПолучениеStreamEvent в http.os меряет время первого запроса к только что запущенному веб-серверу и ждет меньше 600 мс. Первый запрос заметно медленнее следующих, и на медленном агенте не укладывается: в GitHub Actions упал с 868 мс (https://github.com/sfaqer/OneScript/actions/runs/36430898440). Локально на одном ядре без ReadyToRun первый запрос идет 810–830 мс, следующие около 510.

Сервер теперь запускается на свободном порту (ВебСервер(0)), а свойство Порт после запуска возвращает выбранный порт (раньше оставалось 0). Тест ждет, пока у сервера появится порт, делает первый запрос и меряет время на следующем. В конце сервер останавливается.

Summary by CodeRabbit

• New Features
  • When the server starts with automatic port selection, its port now reflects the actual listening port, making the assigned port available after startup.
• Tests
  • Improved test-server readiness checks: requests are made only after the server has bound to a port, and timing begins after an initial request. Tests also stop and clear the server after running, helping ensure test runs do not leave the server running.

📝 Walkthrough

Walkthrough

When configured with port 0, the server now exposes the port selected at startup. The HTTP test waits for that port, sends an initial GET, and then measures a request.

Changes

Dynamic HTTP test server

Layer / File(s)	Summary
Assign the server port after startup src/OneScript.Web.Server/WebServer.cs	Run starts the application and, when Port is 0, assigns the port from the first application URL. It then waits for shutdown and disposes the application in finally. The Port documentation describes the port 0 behavior.
Start the test server and wait for its port tests/http.os	The test server starts on port 0. The StreamEvent test waits for a nonzero port, sends an initial GET, and measures a subsequent request. Test teardown stops the server and clears its reference.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Bug fix

Merge Risk: ⚪ Minimal · up to fbb31

The test uses the runtime-assigned port and warms the server before timing, while host cleanup remains in place. No actionable merge risk is supported.

Security Architecture Review

Security architecture risk: 🔵 Low · up to fbb31

The change is narrowly scoped, with no demonstrated expansion of network access or privileges. It changes server lifecycle and port reporting, while same-instance restart and failure-cleanup behavior remain incompletely established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated behavioral change reaches server callers that request port zero and the changed HTTP test. Network-interface scope is unchanged; complete downstream caller and deployment exposure cannot be determined from the supplied evidence.

Trust Boundaries and Controls

• inferred — Port publication derives from the hosting application's address collection after startup, rather than from HTTP request input. The inspected change does not add a request-controlled path to listener configuration, handler registration, or shutdown authority.

Resilience and Maintainability Implications

• observed — Run and Stop continue to share an application field without an explicit lifecycle or concurrency guard. That ownership pattern predates this PR; supported concurrent use and a worsened failure-containment outcome were not established.

Hardening Proposals

• proposed — If same-instance restart is supported, separate configured port from active listener identity and define terminal-state cleanup. Otherwise, make single-run ownership explicit so Port is not treated as a general readiness guarantee after shutdown or failure.

Надо автовыделение порта сделать, как в недавнем другом PR

[sfaqer]

Сделал: сервер запускается с портом 0. ВебСервер.Порт после запуска теперь возвращает порт, который выбрала система, раньше оставался 0.

discovery, or shutdown waiting throws. Wrap the _app.Start(), Port discovery,
and _app.WaitForShutdown() flow in a try/finally and dispose _app in the finally
block.

Review comments at @tests/http.os:
- Around line 506-531: Ensure the StreamEvent test stops its server if an error
skips normal cleanup: add teardown cleanup that checks whether мВебсервер is
initialized before stopping it. In the test’s normal cleanup, set мВебсервер to
Неопределено after stopping it so teardown does not reuse a stopped server.
