This parameter is ignored in Python 3. :param timeout: Socket timeout in seconds for each individual connection. This can be a float or integer, which sets the timeout for the HTTP request, or an instance of :class:`urllib3.util.Timeout` which gives you more fine-grained control over request timeouts. After the constructor has been parsed, this is always a `urllib3.util.Timeout` object. :param maxsize: Number of connections to save that can be reused. More than 1 is useful in multithreaded situations. If ``block`` is set to False, more connections will be created but they will not be saved once they've been used. :param block: If set to True, no more than ``maxsize`` connections will be used at a time. When no free connections are available, the call will block until a connection has been released. This is a useful side effect for particular multithreaded situations where one does not want to use more than maxsize connections per host to prevent flooding. :param headers: Headers to include with all requests, unless other headers are given explicitly. :param retries: Retry configuration to use by default with requests in this pool. :param _proxy: Parsed proxy URL, should not be used directly, instead, see :class:`urllib3.ProxyManager` :param _proxy_headers: A dictionary with proxy headers, should not be used directly, instead, see :class:`urllib3.ProxyManager` :param \**conn_kw: Additional parameters are used to create fresh :class:`urllib3.connection.HTTPConnection`, :class:`urllib3.connection.HTTPSConnection` instances. �httpNFr c K s� t �| ||� t�| |� || _t|t�s4t�|�}|d u rBtj}|| _ || _ | � |�| _ || _ | | _| pli | _| | _t|�D ]} | j �d � q~d| _d| _| | _| jr�| j�dg � | j| jd< | j| jd< d S )Nr Zsocket_options�proxy� proxy_config)r- r7 r �strict� isinstancer' � from_floatr% ZDEFAULTr �retriesrE �pool�blockrH � proxy_headersrI �xrange�put�num_connections� num_requests�conn_kw� setdefault)r4 r0 r3 rJ r �maxsizerO �headersrM �_proxy�_proxy_headersZ _proxy_configrU �_r5 r5 r6 r7 � s. zHTTPConnectionPool.__init__c C sR | j d7 _ t�d| j | j| jp$d� | jf | j| j| jj| jd�| j ��}|S )z9 Return a fresh :class:`HTTPConnection`. r z(Starting new HTTP connection (%d): %s:%sZ80)r0 r3 r rJ ) rS �log�debugr0 r3 � ConnectionClsr �connect_timeoutrJ rU �r4 �connr5 r5 r6 � _new_conn� s ���z HTTPConnectionPool._new_connc C s� d}z| j j| j|d�}W n> ty6 t| d��Y n$ tjyX | jrTt| d��Y n0 |r�t|�r�t � d| j � |� � t |dd�dkr�d}|p�| �� S ) a� Get a connection.

This is the lowest level call for making a request, so you'll need to specify all the raw details. .. note:: More commonly, it's appropriate to use a convenience method provided by :class:`.RequestMethods`, such as :meth:`request`. .. note:: `release_conn` will only behave as expected if `preload_content=False` because we want to make `preload_content=False` the default behaviour someday soon without breaking backwards compatibility. :param method: HTTP request method (such as GET, POST, PUT, etc.) :param url: The URL to perform the request on. :param body: Data to send in the request body, either :class:`str`, :class:`bytes`, an iterable of :class:`str`/:class:`bytes`, or a file-like object. :param headers: Dictionary of custom headers to send, such as User-Agent, If-None-Match, etc. If None, pool headers are used. If provided, these headers completely replace any pool-specific headers. :param retries: Configure the number of retries to allow before raising a :class:`~urllib3.exceptions.MaxRetryError` exception. Pass ``None`` to retry until you receive a response. Pass a :class:`~urllib3.util.retry.Retry` object for fine-grained control over different types of retries. Pass an integer number to retry connection errors that many times, but no other types of errors. Pass zero to never retry. If ``False``, then retries are disabled and any exception is raised immediately. Also, instead of raising a MaxRetryError on redirects, the redirect response will be returned. :type retries: :class:`~urllib3.util.retry.Retry`, False, or an int. :param redirect: If True, automatically handle redirects (status codes 301, 302, 303, 307, 308). Each redirect counts as a retry. Disabling retries will disable redirect, too. :param assert_same_host: If ``True``, will make sure that the host of the pool requests is consistent else will raise HostChangedError. When ``False``, you can use the pool on an HTTP proxy and request foreign hosts. :param timeout: If specified, overrides the default timeout for this one request. It may be a float (in seconds) or an instance of :class:`urllib3.util.Timeout`. :param pool_timeout: If set and the pool is set to block=True, then this method will block for ``pool_timeout`` seconds and raise EmptyPoolError if no connection is available within the time period. :param release_conn: If False, then the urlopen call will not release the connection back into the pool once a response is received (but will release if you read the entire contents of the response such as when `preload_content=True`). This is useful if you're not preloading the response's content immediately. You will need to call ``r.release_conn()`` on the response ``r`` to return the connection back into the pool. If None, it takes the value of ``response_kw.get('preload_content', True)``. :param chunked: If True, urllib3 will send the body using chunked transfer encoding. Otherwise, urllib3 will send the body using the standard content-length form. Defaults to False. :param int body_pos: Position to seek to in file-like body in the event of a retry or redirect. Typically this won't need to be set because urllib3 will auto-populate the value when needed. :param \**response_kw: Additional parameters are passed to :meth:`urllib3.response.HTTPResponse.from_httplib` N)�redirect�defaultZpreload_contentTr� Fr rz )r �bodyrX r� Zrequest_method)rN � connectionrM c S s* d� t�dt| ��� ��}d|v p(d|v S )N� z[^a-z]zwrong version numberzunknown protocol)�join�re�splitru r1 )Z ssl_error�messager5 r5 r6 �%_is_ssl_error_message_from_http_proxy� s �zIHTTPConnectionPool.urlopen.<locals>._is_ssl_error_message_from_http_proxyz�Your proxy appears to only use HTTP and not HTTPS, try changing your proxy URL to be HTTP.
