Question

oauth library（从Justin.tv Python library page链接）在随机时间无限期地锁定我的Python进程。这是随机发生的，但我的一台服务器上的 OFTEN 。我很肯定这不是由于我的代码中的任何内容，所以我粘贴了与Justin.tv python库和oauth相关的堆栈转储部分：

  File "/home/honstreams/honstreams/website/JtvClient.py", line 51, in get
    return self._send_request(request, token)
  File "/home/honstreams/honstreams/website/JtvClient.py", line 90, in _send_request
    return conn.getresponse()
  File "/usr/lib/python2.6/httplib.py", line 986, in getresponse
    response.begin()
  File "/usr/lib/python2.6/httplib.py", line 391, in begin
    version, status, reason = self._read_status()
  File "/usr/lib/python2.6/httplib.py", line 349, in _read_status
    line = self.fp.readline()
  File "/usr/lib/python2.6/socket.py", line 397, in readline
    data = recv(1)
KeyboardInterrupt

底线是KeyboardInterrupt之前的位置。我会坚持永远，或至少在我让它运行的几天内。

我感兴趣socket.py即使设置了超时也会锁定（有时会超时）以及任何可以阻止的方式。

Justin.tv Python Client Library中的这些行是相关的：

def _send_request(self, request, token=None):
    request.sign_request(OAuthSignatureMethod_HMAC_SHA1(), self.consumer, token)
    conn = self._get_conn() # connection was requested here
    if request.http_method == 'POST':
        conn.request('POST', request.http_url, body=request.to_postdata())
    else:
        conn.request('GET', request.http_url, headers=request.to_header())
    return conn.getresponse()  # Error occurs here

def _get_conn(self):
    return httplib.HTTPConnection("%s:%d" % (self.host, self.port)) # no timeout!

请注意，httplib.HTTPConnection 未通过任何超时。将该代码更改为超时，并确保定义发生超时时发生的情况。

即使设置了超时，python.socket的哪一部分可以想象永远冻结我的脚本？
