This diagram details these state transitions: (null) | | HTTPConnection() v Idle | | putrequest() v Request-started | | ( putheader() )* endheaders() v Request-sent | | response = getresponse() v Unread-response [Response-headers-read] |\____________________ | | | response.read() | putrequest() v v Idle Req-started-unread-response ______/| / | response.read() | | ( putheader() )* endheaders() v v Request-started Req-sent-unread-response | | response.read() v Request-sent This diagram presents the following rules: -- a second request may not be started until {response-headers-read} -- a response [object] cannot be retrieved until {request-sent} -- there is no differentiation between an unread response body and a partially read response body Note: this enforcement is applied by the HTTPConnection class. The HTTPResponse class does not enforce this state machine, which implies sophisticated clients may accelerate the request/response pipeline. Caution should be taken, though: accelerating the states beyond the above pattern may imply knowledge of the server's connection-close behavior for certain requests. For example, it is impossible to tell whether the server will close the connection UNTIL the response headers have been read; this means that further requests cannot be placed into the pipeline until it is known that the server will NOT be closing the connection.

Normally, we have a blocking socket, but a read() can be interrupted by a signal (resulting in a partial read). Note that we cannot distinguish between EOF and an interrupt when zero bytes have been read. IncompleteRead() will be raised in this situation. This function should be used when bytes "should" be present for reading. If the bytes are truly not available (due to EOF), then the IncompleteRead exception can be used to detect the problem. iR.(R4Rwtmint MAXAMOUNTR R%R?R8(R&RyRztchunk((s/usr/lib64/python2.7/httplib.pyRxs cCs |jjS(N(R4tfileno(R&((s/usr/lib64/python2.7/httplib.pyRscCs.|jdkrtn|jj||S(N(RRR$RRh(R&tnametdefault((s/usr/lib64/python2.7/httplib.pyRhs cCs(|jdkrtn|jjS(s&Return list of (header, value) tuples.N(RRR$Rtitems(R&((s/usr/lib64/python2.7/httplib.pyt getheaderss N(RKRLR$RrR]RdReRpRjRaRuRwRvRxRRhR(((s/usr/lib64/python2.7/httplib.pyRus  '  Q   - :   cBseZdZdZeZeZdZdZ dZ dde j ddZdddZdZdZdZd Zd Zd Zd Zd ZddZdddZdZdZddZdidZdZdZe dZ!RS(i sHTTP/1.1iicCs||_||_d|_g|_d|_t|_d|_d|_ d|_ i|_ |dk rr||_ n|j ||\|_|_tj|_dS(N(ttimeouttsource_addressR$RZt_buffert_HTTPConnection__responset_CS_IDLEt_HTTPConnection__stateRQt _tunnel_hostt _tunnel_portt_tunnel_headersRPt _get_hostportthosttporttsockettcreate_connectiont_create_connection(R&RRRPRR((s/usr/lib64/python2.7/httplib.pyR]s            cCsY|jrtdn|j||\|_|_|rH||_n |jjdS(sC Set up host and port for HTTP CONNECT tunnelling.
