S(� s� HyperText Transfer Protocol implementation. This is the basic server-side protocol implementation used by the Twisted Web server. It can parse HTTP 1.0 requests and supports many HTTP 1.1 features as well. Additionally, some functionality implemented here is also useful for HTTP clients (such as the chunked encoding parser). @var CACHED: A marker value to be returned from cache-related request methods to indicate to the caller that a cached response will be usable and no response body should be generated. @var FOUND: An HTTP response code indicating a temporary redirect. @var NOT_MODIFIED: An HTTP response code indicating that a requested pre-condition (for example, the condition represented by an I{If-Modified-Since} header is present in the request) has succeeded. This indicates a response body cached by the client can be used. @var PRECONDITION_FAILED: An HTTP response code indicating that a requested pre-condition (for example, the condition represented by an I{If-None-Match} header is present in the request) has failed. This should typically indicate that the server has not taken the requested action. i ( t divisiont absolute_importt SWITCHINGt OKt CREATEDt ACCEPTEDt NON_AUTHORITATIVE_INFORMATIONt NO_CONTENTt RESET_CONTENTt PARTIAL_CONTENTt MULTI_STATUSt MULTIPLE_CHOICEt MOVED_PERMANENTLYt FOUNDt SEE_OTHERt NOT_MODIFIEDt USE_PROXYt TEMPORARY_REDIRECTt BAD_REQUESTt UNAUTHORIZEDt PAYMENT_REQUIREDt FORBIDDENt NOT_FOUNDt NOT_ALLOWEDt NOT_ACCEPTABLEt PROXY_AUTH_REQUIREDt REQUEST_TIMEOUTt CONFLICTt GONEt LENGTH_REQUIREDt PRECONDITION_FAILEDt REQUEST_ENTITY_TOO_LARGEt REQUEST_URI_TOO_LONGt UNSUPPORTED_MEDIA_TYPEt REQUESTED_RANGE_NOT_SATISFIABLEt EXPECTATION_FAILEDt INTERNAL_SERVER_ERRORt NOT_IMPLEMENTEDt BAD_GATEWAYt SERVICE_UNAVAILABLEt GATEWAY_TIMEOUTt HTTP_VERSION_NOT_SUPPORTEDt INSUFFICIENT_STORAGE_SPACEt NOT_EXTENDEDt RESPONSESt CACHEDt urlparset parse_qst datetimeToStringt datetimeToLogStringt timegmt stringToDatetimet toChunkt fromChunkt parseContentRanget StringTransportt HTTPClientt NO_BODY_CODESt Requestt PotentialDataLosst HTTPChannelt HTTPFactoryN( t BytesIO( t ParseResultR.

If this L{Request}'s channel is paused, the notification will not be delivered. This can happen in one of two ways; either you can call C{request.transport.pauseProducing} yourself, or, 2. In order to deliver this notification promptly when a client disconnects, the reactor must continue reading from the transport, so that it can tell when the underlying network connection has gone away. Twisted Web will only keep reading up until a finite (small) maximum buffer size before it gives up and pauses the transport itself. If this occurs, you will not discover that the connection has gone away until a timeout fires or until the application attempts to send some data via L{Request.write}. 3. It is theoretically impossible to distinguish between successfully I{sending} a response and the peer successfully I{receiving} it. There are several networking edge cases where the L{Deferred}s returned by C{notifyFinish} will indicate success, but the data will never be received. There are also edge cases where the connection will appear to fail, but in reality the response was delivered. As a result, the information provided by the result of the L{Deferred}s returned by this method should be treated as a guess; do not make critical decisions in your applications based upon it. @rtype: L{Deferred} @return: A L{Deferred} which will be triggered when the request is finished -- with a L{None} value if the request finishes successfully or with an error if the request is interrupted by an error (for example, the client closing the connection prematurely). i����( R R� Rd ( R� ( ( sS /opt/cpanel-ccs/.develop/virtualenv/lib/python2.7/site-packages/twisted/web/http.pyt notifyFinish s (c C` s� | j r t d � � n | j r8 t j d d d �d S| j sQ | j d � n | j rm | j j d � n t | j d � r� | j j d k r� | j j j | � n d | _ | j s� | j � n d S( sV Indicate that all response data has been written to this L{Request}. sq Request.finish called on a request after its connection was lost; use Request.notifyFinish to keep track of this.s% Warning! request.finish called twice.t stackleveli NR� s 0 t factoryi ( t _disconnectedR, t finishedt warningst warnt startedWritingR� t chunkedR t hasattrR^ R� R\ R( R4 ( R� ( ( sS /opt/cpanel-ccs/.develop/virtualenv/lib/python2.7/site-packages/twisted/web/http.pyt finish2 s c C` sT | j r t d � � n | j r% d S| j s�d | _ | j } t | j � } | j } g } | d k r� | j j d � d k r� | j d k r� | j t k r� | j d � d | _ n | j d k r| j j d � r� | j j d � q| j j d t | j � g � n | j d k r:| j j d | j g � n xA | j j � D]0 \ } } x! | D] } | j | | f � q]WqJWx$ | j D] } | j d | f � q�W| j j | | | | � | j d k r�d � | _ d S| j t k r�d � | _ d Sn | j t | � | _ | rP| j r=| j j t | � � qP| j j | � n d S( s� Write some data as a result of an HTTP request.

This protocol can interpret the contents of a request or response body which uses the I{chunked} Transfer-Encoding. It cannot interpret any of the rest of the HTTP protocol. It may make sense for _ChunkedTransferDecoder to be an actual IProtocol implementation. Currently, the only user of this class will only ever call dataReceived on it. However, it might be an improvement if the user could connect this to a transport and deliver connection lost notification. This way, `dataCallback` becomes `self.transport.write` and perhaps `finishCallback` becomes `self.transport.loseConnection()` (although I'm not sure where the extra data goes in that case). This could also allow this object to indicate to the receiver of data that the stream was not completely received, an error case which should be noticed. -exarkun @ivar dataCallback: A one-argument callable which will be invoked each time application data is received. @ivar finishCallback: A one-argument callable which will be invoked when the terminal chunk is received.

The L{HTTPChannel} provides L{interfaces.ITransport} and L{interfaces.IConsumer} to the L{Request} objects it creates.

Used to attempt to prevent the transport from producing excess data when we're responding to a request. @type _networkProducer: L{interfaces.IPushProducer} @ivar _requestProducer: If the L{Request} object or anything it calls registers itself as an L{interfaces.IProducer}, it will be stored here. This is used to create a producing pipeline: pause/resume producing methods will be propagated from the C{transport}, through the L{HTTPChannel} instance, to the c{_requestProducer}. The reason we proxy through the producing methods rather than the old behaviour (where we literally just set the L{Request} object as the producer on the transport) is because we want to be able to exert backpressure on the client to prevent it from sending in arbitrarily many requests without ever reading responses. Essentially, if the client never reads our responses we will eventually stop reading its requests. @type _requestProducer: L{interfaces.IPushProducer} @ivar _requestProducerStreaming: A boolean that tracks whether the producer on the L{Request} side of this channel has registered itself as a L{interfaces.IPushProducer} or an L{interfaces.IPullProducer}. @type _requestProducerStreaming: L{bool} or L{None} @ivar _waitingForTransport: A boolean that tracks whether the transport has asked us to stop producing. This is used to keep track of what we're waiting for: if the transport has asked us to stop producing then we don't want to unpause the transport until it asks us to produce again. @type _waitingForTransport: L{bool} @ivar abortTimeout: The number of seconds to wait after we attempt to shut the transport down cleanly to give up and forcibly terminate it. This is only used when we time a connection out, to prevent errors causing the FD to get leaked. If this is L{None}, we will wait forever. @type abortTimeout: L{int} @ivar _abortingCall: The L{twisted.internet.base.DelayedCall} that will be used to forcibly close the transport if it doesn't close cleanly. @type _abortingCall: L{twisted.internet.base.DelayedCall} @ivar _optimisticEagerReadSize: When a resource takes a long time to answer a request (via L{twisted.web.server.NOT_DONE_YET}, hopefully one day by a L{Deferred}), we would like to be able to let that resource know about the underlying transport disappearing as promptly as possible, via L{Request.notifyFinish}, and therefore via C{self.requests[...].connectionLost()} on this L{HTTPChannel}. However, in order to simplify application logic, we implement head-of-line blocking, and do not relay pipelined requests to the application until the previous request has been answered. This means that said application cannot dispose of any entity-body that comes in from those subsequent requests, which may be arbitrarily large, and it may need to be buffered in memory. To implement this tradeoff between prompt notification when possible (in the most frequent case of non-pipelined requests) and correct behavior when not (say, if a client sends a very long-running GET request followed by a PUT request with a very large body) we will continue reading pipelined requests into C{self._dataBuffer} up to a given limit. C{_optimisticEagerReadSize} is the number of bytes we will accept from the client and buffer before pausing the transport.

This will be called by the transport when the send buffers have been filled up. We want to simultaneously pause the producing L{Request} object and also pause our transport. The logic behind pausing the transport is specifically to avoid issues like https://twistedmatrix.com/trac/ticket/8868. In this case, our inability to send does not prevent us handling more requests, which means we increasingly queue up more responses in our send buffer without end. The easiest way to handle this is to ensure that if we are unable to send our responses, we will not read further data from the connection until the client pulls some data out. This is a bit of a blunt instrument, but it's ok. Note that this potentially interacts with timeout handling in a positive way. Once the transport is paused the client may run into a timeout which will cause us to tear the connection down. That's a good thing!
