Commit 59a2582
fix(web/server): address PR review feedback on the dev-backend port
- sandbox-controller: resolve start() with empty values on listen error
(e.g. EADDRINUSE on a fixed MCP_SANDBOX_PORT) instead of leaving the
promise pending forever. Without this, the Vite plugin's
`await sandboxController.start()` could hang the entire dev backend on a
port collision. Banner now silently omits the sandbox line; getUrl()
keeps returning null. Adds a regression test exercising the EADDRINUSE
path against a real socket.
- vite-hono-plugin: listen for `error` and `close` on the incoming request
stream (in addition to `end`) so an aborted POST/PUT (browser navigates
mid-upload) doesn't leak the middleware indefinitely.
- vite-hono-plugin: add a `.catch()` to the initial `pump()` kickoff so a
sync throw before the first `await reader.read()` can't surface as an
unhandled rejection.
- sandbox_proxy.html: drop the stale CSP comment — v1.5's sandbox HTTP
server never set CSP either; this PR doesn't regress anything. Replace
with the actual isolation model (iframe sandbox attribute + origin
allowlist) so future readers don't assume a CSP header is enforced.
- Hoist `WebServerHandle` to a shared `server/types.ts` so the future
launcher port (#1246) doesn't need to pick one of two duplicate
declarations.
- Extract `resolveAutoOpen()` helper out of the triple-nested ternary in
`buildWebServerConfigFromEnv` for legibility, with the three-way logic
documented in one place.
- Add an inline comment explaining why
`webServerConfigToInitialPayload` falls back to streamable-http for
unknown discriminators (forward-compat with future SDK transports)
rather than throwing.
