Circus WEBUI无效

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

起初似乎有效：

# circusd circus.ini

但是如果我尝试从endpoint连接到WEBUI（ 127.0.0.1:5555 ）：

Traceback (most recent call last):

    f.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

可能有什么不对？似乎是circus代码中的错误。

有cure：

          if not endpoints:

很遗憾它没有找到pip的路。
