Fix issue with WSGI container error

[johnnadratowski]

I'm using Flask v3 and Python 3.11. When starting up my server I got the following error (and it seems I'm not the only one):

    Traceback (most recent call last):
      File "/Users/john/venv/ema-cSETeqck/lib/python3.11/site-packages/tornado/web.py", line 1767, in _execute
        result = self.prepare()
                 ^^^^^^^^^^^^^^
      File "/Users/john/venv/ema-cSETeqck/lib/python3.11/site-packages/tornado/web.py", line 3149, in prepare
        self.fallback(self.request)
      File "/Users/john/venv/ema-cSETeqck/lib/python3.11/site-packages/livereload/server.py", line 135, in __call__
        app_response = self.wsgi_app(WSGIContainer.environ(request), start_response)
                                     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    TypeError: WSGIContainer.environ() missing 1 required positional argument: 'request'

This fix is simple, and fixes the issue on my system.

This fix worked in my system as well, in my project using Flask as the wsgi app.

Necessary Bugfix!

For those waiting on this fix (mentioned in #270 ), I've written a monkeypatch using wrapt that did the job for now:

import wrapt

def patch_livereload_to_fix_bug_around_wsgi_support():  
    """
    This patch is to fix the error descrbed here: https://stackoverflow.com/questions/78039400/flask-with-livereload-and-tornado-causing-error-when-i-run-my-program
    This implements the fix proposed in https://github.com/lepture/python-livereload/pull/275
    """

    from livereload.server import WSGIContainer


    @wrapt.patch_function_wrapper('livereload.server', 'LiveScriptContainer.__call__')
    def patched_call(wrapped, instance, args, kwargs):
        """
        LiveScriptContainer.__call__ is trying to call an instance method of its parent class as a static method.
        The problem is that it was changed from a static method in some change, and this is what broke things.
        Here, we trick the __call__ method into using a WSGIContainer instance instead of the type.
        """
        wrapped.__globals__['WSGIContainer'] = WSGIContainer(wsgi_application=instance.wsgi_app)
        return wrapped(*args, **kwargs)
