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.

📝 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.

Merge Risk: ⚪ Minimal · up to f1560

The test server now uses an OS-assigned port, waits for it, and completes a finite warm-up request before timing the next request. The inspected startup and cleanup paths support the intended behavior; no actionable merge risk remains.

Security Architecture Review

Security architecture risk: 🔵 Low · up to f1560

The test now uses a system-selected port, but the server’s public lifecycle also changes. Repeated or overlapping starts may affect port selection and shutdown. No new network binding scope or verified security vulnerability was identified.

Retained concerns

• Low · reliability · inferred: A server constructed with port 0 binds to its previously assigned port on a subsequent Run, rather than requesting another available port. This can cause a restart to fail if that port has since been taken.
• Low · reliability · inferred: With overlapping Run calls, the newly added cleanup can dispose the application currently held in _app rather than the application started by that call, weakening lifecycle ownership and shutdown containment.

Security review details

Security Blast Radius

• inferred — The newly published port is visible to a script holding its WebServer instance; the demonstrated caller is the HTTP test. Evidence does not establish which other script callers can access this object in deployed environments.

Trust Boundaries and Controls

• observed — Script code can select the listener port through the existing constructor, while ConfigureApp binds it on all interfaces. The changed test reads the assigned port but sends its requests to loopback.

Resilience and Maintainability Implications

• inferred — The new shared-field disposal path warrants lifecycle isolation if overlapping starts are permitted; the supplied test exercises one server start and calls Stop during teardown.

Hardening Proposals

• proposed — If the test listener needs to be reachable only locally, bind it to loopback rather than relying on a loopback client address; this would narrow a pre-existing all-interface exposure, not remedy a newly introduced bind change.

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.

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.
