调研方向
Start by reviewing the server startup path in livereload.server and the web.Application and Server references shown in the issue. Use the monkeypatch example to understand the requested random-port and browser-opening behavior. Done means the server supports these flows without delays and exposes enough startup hooks for subclassing or customization.

描述
Hello,
I wanted to support opening a browser on a random local port, and got it working with a bit of monkeypatching:
server = make_server(…)
import tornado.web
import tornado.httpserver
import tornado.netutil
import webbrowser
class Application(tornado.web.Application):
def listen(self, *args, **kw):
sockets = tornado.netutil.bind_sockets(0, 'localhost')
server = tornado.httpserver.HTTPServer(self)
server.add_sockets(sockets)
pairs = []
for s in sockets:
pairs.append(s.getsockname()[:2])
pairs.sort()
host, port = pairs[0]
if ":" in host:
host = f"[{host}]"
url = f"http://{host}:{port}"
log.info("Listening on %s", url)
async def open_browser():
webbrowser.open_new_tab(url)
tornado.ioloop.IOLoop.current().add_callback(open_browser)
return server
# Monkey patch to be able to start servers in a smoother way that the
# defaults of livereload
import livereload.server
livereload.server.web.Application = Application
server.serve()
Integrating this in livereload seems to require some refactoring of how the server is started, and I didn't engage on it. I hope that my monkeypatched code can be a useful reference.
Ideally, I would have liked to be able to subclass Server or the Application used by server, and have enough hooks to intervene in the listening bit.
