* feat(agent-host): gate inbound filesystem RPCs with a permission service

Reverse `resource{Read,List,Write,Delete,Move}` from remote agent hosts
were routed straight to `IFileService` with no authorization. Add a
permission service that gates each reverse RPC, returns typed
`PermissionDenied` with `data.request`, handles negotiation via the new
`resourceRequest` reverse RPC, and surfaces a Deny / Allow / Always Allow
prompt above the chat input.

URIs are canonicalized through `IFileService.realpath` before comparison
so `..` and symlinks can't escape grants. Implicit read grants are
auto-registered for customization URIs the client sends to the host, so
plugin sync remains friction-free. Always-Allow grants persist into a
new user setting, `chat.agentHost.localFilePermissions`.

Unit Tests

Run (inside Electron)

./scripts/test.[sh|bat]

All unit tests are run inside a Electron renderer environment which access to DOM and Nodejs api. This is the closest to the environment in which VS Code itself ships. Notes:

  • use the --debug to see an electron window with dev tools which allows for debugging
  • to run only a subset of tests use the --run or --glob options
  • use npm run watch to automatically compile changes

For instance, ./scripts/test.sh --debug --glob **/extHost*.test.js runs all tests from extHost-files and enables you to debug them.

Run (inside browser)

npm run test-browser -- --browser webkit --browser chromium

Unit tests from layers common and browser are run inside chromium, webkit, and (soon'ish) firefox (using playwright). This complements our electron-based unit test runner and adds more coverage of supported platforms. Notes:

  • these tests are part of the continuous build, that means you might have test failures that only happen with webkit on windows or chromium on linux
  • you can run these tests locally via npm run test-browser -- --browser chromium --browser webkit
  • to debug, open <vscode>/test/unit/browser/renderer.html inside a browser and use the ?m=<amd_module>-query to specify what AMD module to load, e.g file:///Users/jrieken/Code/vscode/test/unit/browser/renderer.html?m=vs/base/test/common/strings.test runs all tests from strings.test.ts
  • to run only a subset of tests use the --run or --glob options

Note: you can enable verbose logging of playwright library by setting a DEBUG environment variable before running the tests (https://playwright.dev/docs/debug#verbose-api-logs)

Run (with node)

npm run test-node -- --run src/vs/editor/test/browser/controller/cursor.test.ts

Coverage

The following command will create a coverage folder in the .build folder at the root of the workspace:

OS X and Linux

./scripts/test.sh --coverage

Windows

scripts\test --coverage
