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.connectionpool.ProxyManager`" :param _proxy_headers: A dictionary with proxy headers, should not be used directly, instead, see :class:`urllib3.connectionpool.ProxyManager`" :param \**conn_kw: Additional parameters are used to create fresh :class:`urllib3.connection.HTTPConnection`, :class:`urllib3.connection.HTTPSConnection` instances. thttpic K@stj|||tj||||_t|tsMtj|}n|dkretj }n||_ ||_ |j ||_ ||_| |_| pi|_x$t|D]} |j jdqWd|_d|_| |_|jr |jjdgndS(Nitsocket_options(R#R*Rtstrictt isinstanceR t from_floatR7RtDEFAULTRtretriesR:tpooltblocktproxyt proxy_headerstxrangetputtnum_connectionst num_requeststconn_kwt setdefault( R)R&R(R>RtmaxsizeRDtheadersRBt_proxyt_proxy_headersRKt_((sF/usr/lib/python2.7/site-packages/pip/_vendor/urllib3/connectionpool.pyR*s(           c C@se|jd7_tjd|j|j|jd|jd|jd|jjd|j|j }|S(s9 Return a fresh :class:`HTTPConnection`. is%Starting new HTTP connection (%d): %sR&R(RR>( RItlogtdebugR&t ConnectionClsR(Rtconnect_timeoutR>RK(R)tconn((sF/usr/lib/python2.7/site-packages/pip/_vendor/urllib3/connectionpool.pyt _new_conns  cC@sd }y"|jjd|jd|}WnNtk rJt|dn/tjk rx|jryt|dqynX|rt |rt j d|j |j t|dddkrd }qn|p|jS( s 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 body: Data to send in the request body (useful for creating POST requests, see HTTPConnectionPool.post_url for more convenience). :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` tredirecttdefaulttpreload_contentR<RRotbodyRNRtrequest_methodRCt connectionRBs"No pool connections are available.sCannot connect to proxy.sConnection aborted.Rt_poolt _stacktraceiNs1Retrying (%r) after connection broken by '%r': %st pool_timeoutt release_conntbody_posc S@s:y|jWn%ttttttfk r5}nXdS(N(treadR RRRRR (tresponseR((sF/usr/lib/python2.7/site-packages/pip/_vendor/urllib3/connectionpool.pytdrain_and_release_conns  i/tGETRsRedirecting %s -> %stassert_same_hosts Retry-Afters Retry: %s(9R7RNR?Rtfrom_intRBRYR|RRR8tcopytupdateRFR0RReR]RURRER\RbRt ResponseClst from_httplibRR[RR RRRRR RRR t incrementtsysRrtsleepR/R`RRR_turlopentget_redirect_locationRR traise_on_redirecttsleep_for_retryRStboolt getheadertis_retrytraise_on_status(R)RRlRRNRBRRRRRRRt response_kwRVtrelease_this_connRkt clean_exitRtis_new_proxy_connRt response_connRRRtredirect_locationthas_retry_after((sF/usr/lib/python2.7/site-packages/pip/_vendor/urllib3/connectionpool.pyRs^  !
