This when mixed with a subclass of httplib.HTTPConnection (though technically we subclass from urllib3, which subclasses httplib.HTTPConnection) and we only override this class to support Expect 100-continue, which we need for S3. As far as I can tell, this is general purpose enough to not be specific to S3, but I'm being tentative and keeping it in botocore because I've only tested this against AWS services. cs*tt|j|||j|_d|_d|_dS)NF)superrrresponse_class_original_response_cls_response_received_expect_header_set)rrr) __class__rrr@s zAWSConnection.__init__cs&tt|d|_d|_|j|_dS)NF)rrcloser r!rr)r)r"rrr#NszAWSConnection.closecsTd|_|dddkrd|_nd|_|j|_tt|j||||f||}d|_|S)NFZExpects 100-continueT)r getr!rrrr _send_request)rmethodurlbodyheadersrrrval)r"rrr&Us zAWSConnection._send_requestcCsHg}x4|D],}t|tjr,||dq ||q Wd|}|S)Nzutf-8s ) isinstancer text_typeappendencodejoin)rZ mixed_bufferZ bytes_bufferchunkmsgrrr_convert_to_bytesas   zAWSConnection._convert_to_bytesNcOs|jd||j}|jdd=t|tr:||7}d}|||jr|tdt j |j drr| |dStd|dk r||dS)N)r$r$z"Waiting for 100 Continue response.zCNo response seen from server, continuing to send the response body.)_bufferextendr3r,bytessendr!loggerdebugurllib3util wait_for_readsock_handle_expect_response)r message_bodyrrr2rrr _send_outputns        zAWSConnection._send_outputcCsd}x|dkr|}qWdS)Ns )readline)rfpcurrentrrr_consume_headerss zAWSConnection._consume_headerscCs|jdd}z|}|dd}||rN||td||ndt |dkr|d drtd|d dt |d |d df}t jt|d }||_d |_Wd|XdS) Nrbrz5100 Continue response seen, now sending request body.sHTTP/zOReceived a non 100 Continue response from the server, NOT sending request body.asciir4)rT)r>makefilerBsplit_is_100_continue_statusrEr9r:_send_message_bodylen startswithdecodeint functoolspartialrrr r#)rr@rCmaybe_status_linepartsrrrrrr?s"         z%AWSConnection._handle_expect_responsecCs|dk r||dS)N)r8)rr@rrrrMsz AWSConnection._send_message_bodycs$|jrtddStt||S)Nz@send() called, but reseponse already received.

However, the logic has been boiled down to meet the specific use cases in botocore. Of note there are the following differences: This class does not heavily prepare the URL. Requests performed many validations and corrections to ensure the URL is properly formatted. Botocore either performs these validations elsewhere or otherwise consistently provides well formatted URLs. This class does not heavily prepare the body. Body preperation is simple and supports only the cases that we document: bytes and file-like objects to determine the content-length. This will also additionally prepare a body that is a dict to be url encoded params string as some signers rely on this. Finally, this class does not support multipart file uploads. This class does not prepare the method, auth or cookies. cCs<|j}||}||}|||}|j}t|||||S)N)r' _prepare_url _prepare_body_prepare_headers stream_outputAWSPreparedRequest)roriginalr'r(r)r*rxrrrprepareRs    zAWSRequestPreparer.preparecCs2|j}|jr.tt|jdd}d||f}|S)NT)doseqz%s?%s)r(paramsr listitems)rrzr(r}rrrru[s  zAWSRequestPreparer._prepare_urlNcCslt|j}d|ksd|kr"|S|jdkrh||}|dk rLt||d<nt|}td|d|d<|S)NzTransfer-EncodingzContent-Length)GETHEADOPTIONSz Failed to determine length of %schunked) HeadersDictr*rr'_determine_content_lengthrVtyper9r:)rrzZ prepared_bodyr*lengthZ body_typerrrrwbs   z#AWSRequestPreparer._prepare_headerscCs<|\}}t|tjr|d}t|tjr4|d}||fS)Nzutf-8)r,rr-r/)ritemkeyvaluerrr_to_utf8ws     zAWSRequestPreparer._to_utf8csB|j}|dkrd}t|tr>fdd|D}t|dd}|S)z"Prepares the given HTTP body data.r$Ncsg|]}|qSr)r).0r)rrr sz4AWSRequestPreparer._prepare_body..T)r|)rkr,dictrr )rrzr)r}r)rrrvs  z AWSRequestPreparer._prepare_bodyc Cs|sdSyt|Sttfk r6}zWdd}~XYnXt|drt|dry.|}|dd|}||||Stjk rYnXdS)NrseektellrG)rNAttributeError TypeErrorhasattrrrioUnsupportedOperation)rr)eZorig_posZ end_file_posrrrrs   z,AWSRequestPreparer._determine_content_length)N) rrrrWr{rurwrrvrrrrrrt>s   rtc@s2eZdZdZeZd ddZddZedd Z dS) rla Represents the elements of an HTTP request.
