马戏团WEBUI不工作

Question

我有以下circus配置：

[circus] 
pidfile  = /tmp/circus.pid 
check_delay = 5 
statsd  = True 
httpd   = True 
httpd_host = 10.3.2.1 
httpd_port = 8888 
endpoint  = tcp://127.0.0.1:5555 
pubsub_endpoint = tcp://127.0.0.1:5556 
stats_endpoint = tcp://127.0.0.1:5557 
stream_backend = thread 

[watcher:my_app] 
working_dir = /var/www/my_app/ 
cmd   = /usr/local/bin/waitress-serve 
args   = --unix-socket='/tmp/my_app.socket' --threads=16 --http_app:main 
uid   = www-data 
gid   = www-data 
numprocesses = 1 
warmup_delay = 0 
use_sockets = True 
graceful_timeout = 2 
stderr_stream.class = StdoutStream 

乍看起来工作：

# circusd circus.ini 
2016-12-02 18:21:15 circus[6406] [INFO] Starting master on pid 6406 
2016-12-02 18:21:15 circus[6406] [INFO] sockets started

Serving on http://unix:/tmp/my_app.socket 
2016-12-02 18:21:16 circus-web[6415] [INFO] Starting circus web ui on fd 6 

不过，如果我尝试连接到endpoint（127.0。 0.1：5555）来自WEBUI：

Traceback (most recent call last): 
    File "/usr/local/lib/python2.7/dist-packages/tornado/web.py", line 1425, in _stack_context_handle_exception 
    raise_exc_info((type, value, traceback)) 
    File "/usr/local/lib/python2.7/dist-packages/tornado/stack_context.py", line 314, in wrapped 
    ret = fn(*args, **kwargs) 
    File "/usr/local/lib/python2.7/dist-packages/tornado/web.py", line 1638, in future_complete 
    f.result() 
    File "/usr/local/lib/python2.7/dist-packages/tornado/concurrent.py", line 237, in result 
    raise_exc_info(self._exc_info) 
    File "/usr/local/lib/python2.7/dist-packages/tornado/gen.py", line 285, in wrapper 
    yielded = next(result) 
    File "/usr/local/lib/python2.7/dist-packages/circusweb/circushttpd.py", line 164, in post 
    endpoints = self.get_arguments('endpoint_list', []) 
    File "/usr/local/lib/python2.7/dist-packages/tornado/web.py", line 412, in get_arguments 
    assert isinstance(strip, bool) 
AssertionError 

什么可能是错的？看起来像circus代码中的错误。

有一个cure：

@@ -161,11 +161,11 @@ def get(self): 
     @gen.coroutine 
     def post(self): 
      endpoints_list = list(self.session.endpoints) 
-  endpoints = self.get_arguments('endpoint_list', []) 
+  endpoints = self.get_arguments('endpoint_list') 

      # If no selection in list 
      if not endpoints: 
-   endpoints = self.get_arguments('endpoint_direct', []) 
+   endpoints = self.get_arguments('endpoint_direct') 

      if not endpoints: 
       self.redirect(self.reverse_url('disconnect')) 

这是一个耻辱，却没有发现它的方式pip。
