feat(cli): auto-retry next port when serve port is in use (#6513)
* feat(cli): auto-retry next port when serve port is in use

When `qwen serve` or `npm run dev:daemon` encounters EADDRINUSE on the
default port (4170), automatically try the next available port (up to 10
attempts) instead of failing immediately. This allows running multiple
daemon instances side-by-side without manual port management.

- run-qwen-serve.ts: replace single listen() with recursive tryListen()
  that retries on EADDRINUSE; --port 0 (ephemeral) skips retry
- daemon-dev.js: pre-scan for an available port via net probe before
  spawning the daemon child, ensuring health-poll and web-shell target
  the correct URL
- Tests: retry-then-succeed, non-EADDRINUSE immediate-fail, and existing
  all-ports-exhausted test all pass (138 tests)

* test(cli): fix EADDRINUSE mock to create fresh server per listen attempt

The existing test reused a single fakeServer across all retry attempts,
accumulating 10+ once('listening') listeners and triggering a
MaxListenersExceededWarning. Create a new server per call to match
production behavior where each tryListen creates a fresh server.

* fix: address review feedback on port retry

- daemon-dev.js: strip IPv6 brackets before probe (ENOTFOUND fix),
  add port range/NaN validation
- run-qwen-serve.ts: remove duplicate runtime error listener
  (onListening already installs one via removeAllListeners + on)
- tests: add exhaustion (all 10 ports), port 0 EADDRINUSE no-retry,
  and stderr retry message assertion (140 tests pass)

* fix: update stale comment referencing removed server.once('error', reject)

* fix: address R2 review — port cap, TLS reuse, exhaustion summary

- daemon-dev.js: cap probe at port 65535, skip probe when user
  specifies --port, add --compacted-replay-max-bytes to whitelist
- run-qwen-serve.ts: move https.createServer before tryListen (avoid
  recreating TLS context per retry), cap retry at 65535, log summary
  "all ports X–Y are in use" on exhaustion
- tests: verify exhaustion summary stderr message

* fix: clear stale listening listeners on httpsServer before retry

QwenLM%2Fqwen-code | Trendshift

The open-source AI coding agent that lives in your terminal.

中文 | Deutsch | français | 日本語 | Русский | Português (Brasil)

Why Qwen Code?

  • Agentic out of the box — Auto-Memory, Auto-Skills, SubAgents, Agent Teams, and MCP. Dynamic workflows, zero setup.
  • Open-source, inside and out — The framework and the Qwen models are open-source. They evolve together. No vendor lock-in.
  • Multi-protocol — Supports OpenAI, Anthropic, Gemini, and Qwen APIs. Any third-party provider or local model (Ollama / vLLM). Switch at runtime.
  • Beyond the terminal — IDE plugins, Desktop app, daemon mode, SDKs, and IM bots (Telegram / DingTalk / WeChat / Feishu).

Tip

Qwen Code is actively iterating on itself — using its own agent and models to file issues, submit PRs, review code, and run tests. Powered by the community, driven by AI.

Installation

Linux / macOS:

curl -fsSL https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/install-qwen-standalone.sh | bash

Windows:

irm https://qwen-code-assets.oss-cn-hangzhou.aliyuncs.com/installation/install-qwen-standalone.ps1 | iex

Restart your terminal after installation to ensure environment variables take effect.

NPM / Homebrew

NPM (requires Node.js 22+):

npm install -g @qwen-code/qwen-code@latest

Homebrew (macOS / Linux):

brew install qwen-code

Quick Start

qwen          # Launch interactive terminal UI
# Inside the session:
/auth         # Configure your provider and API key

See the Authentication Guide and Settings Reference for detailed setup.

Contributions are welcome! See CONTRIBUTING.md for guidelines.

Acknowledgments

This project was originally based on Google Gemini CLI v0.8.2. We gratefully acknowledge the Gemini CLI team's excellent work. Starting from Qwen Code v0.1, we stopped syncing with upstream and began independent development as a multi-protocol, multi-platform agent framework with deep integrations for Qwen models and beyond.
