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|_dSNF)superrrresponse_class_original_response_cls_response_received_expect_header_setr __class__rrr?s zAWSConnection.__init__cs&tt|d|_d|_|j|_dSr)r rcloser#r$r"r!rr%rrr'MszAWSConnection.closecsTd|_|dddkrd|_nd|_|j|_tt|j||||f||}d|_|S)NFZExpects 100-continueT)r#getr$r"r!r r _send_request)rmethodurlbodyheadersrrrvalr%rrr+Ts" zAWSConnection._send_requestcCsDg}|D],}t|tjr*||dq||qd|}|S)Nutf-8 ) isinstancer text_typeappendencodejoin)rZ mixed_bufferZ bytes_bufferchunkmsgrrr_convert_to_bytes`s   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.)_bufferextendr:r3bytessendr$loggerdebugurllib3util wait_for_readsock_handle_expect_response)r message_bodyrrr9rrr _send_outputms        zAWSConnection._send_outputcCsd}|dkr|}qdS)Nr2)readline)rfpcurrentrrr_consume_headersszAWSConnection._consume_headerscCs|jdd}z|}|dd}||rN||td| |ndt |dkr|d drtd|d dt |d |d df}tjt|d }||_d |_W5|XdS) Nrbrz5100 Continue response seen, now sending request body.HTTP/zOReceived a non 100 Continue response from the server, NOT sending request body.asciir;)rT)rEmakefiler'rIsplit_is_100_continue_statusrLr@rA_send_message_bodylen startswithdecodeint functoolspartialrr!r#)rrGrJmaybe_status_linepartsrr!rrrrFs*         z%AWSConnection._handle_expect_responsecCs|dk r||dSr)r?)rrGrrrrUsz AWSConnection._send_message_bodycs$|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|||||Sr)r, _prepare_url _prepare_body_prepare_headers stream_outputAWSPreparedRequest)roriginalr,r-r.r/rrrrprepareQs    zAWSRequestPreparer.preparecCs2|j}|jr.tt|jdd}d||f}|S)NTdoseqz%s?%s)r-paramsr listitems)rrr-rrrrr~Zs  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_lengthr^typer@rA)rrZ prepared_bodyr/lengthZ body_typerrrras   z#AWSRequestPreparer._prepare_headerscCs<|\}}t|tjr|d}t|tjr4|d}||fSNr1)r3rr4r6)ritemkeyvaluerrr_to_utf8vs     zAWSRequestPreparer._to_utf8csB|j}|dkrd}t|tr>fdd|D}t|dd}|S)z"Prepares the given HTTP body data.r)Ncsg|]}|qSr)r).0rr(rr sz4AWSRequestPreparer._prepare_body..Tr)rtr3dictrr )rrr.rrr(rr~s  z AWSRequestPreparer._prepare_bodyc Cs|sdSz t|WSttfk r8}zW5d}~XYnXt|dr|t|dr||}|dd|}||||SdS)NrseektellrN)rVAttributeError TypeErrorhasattrrr)rr.eZorig_posZ end_file_posrrrrs   z,AWSRequestPreparer._determine_content_length)N) rrrr_rr~rrrrrrrrr}=s   r}c@s2eZdZdZeZd ddZddZedd Z dS) rua Represents the elements of an HTTP request.
