This diagram details these state transitions: (null) | | HTTPConnection() v Idle | | putrequest() v Request-started | | ( putheader() )* endheaders() v Request-sent |\_____________________________ | | getresponse() raises | response = getresponse() | ConnectionError v v Unread-response Idle [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 <amt> 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. r r9 )r= ry �min� MAXAMOUNTr rA r/ r, )r0 r{ r} �chunkr r r rz f s zHTTPResponse._safe_readc C s� d}t |�}xt|t|�k r�tt|�k r@|dt� }| jj|�}n | jj|�}|sjtt|d|� �t|���||d� }||7 }qW |S )z2Same as _safe_read, but for reading into a buffer.r N)rv r, r� r= ru r r� )r0 r| r� r� r� r1 r r r r� } s zHTTPResponse._safe_readintor* c C s� | j dks| jdkrdS | jr(| j|�S | jdk rJ|dk sD|| jkrJ| j}y| j j|�}W n* tk r� |dkrt� | j jd�}Y nX | r�|r�| j� n | jdk r�| jt|�8 _|S )zvRead with at most one underlying system call.

When the method is HTTP, these headers are those returned by the server at the head of the retrieved HTML page (including Content-Length and Content-Type). When the method is FTP, a Content-Length header will be present if (as is now usual) the server passed back a file length in response to the FTP retrieval request. A Content-Type header will be present if the MIME type can be guessed. When the method is local-file, returned headers will include a Date representing the file's last-modified time, a Content-Length giving file size, and a Content-Type containing a guess at the file's type.

If the HTTPConnection is in the correct state, returns an instance of HTTPResponse or of whatever object is returned by the response_class variable.
