class documentation

class _WSGIResponse: (source)

Constructor: _WSGIResponse(reactor, threadpool, application, request)

Helper for WSGIResource which drives the WSGI application using a threadpool and hooks it up to the http.Request.

Method	`__init__`	Undocumented
Method	`run`	Call the WSGI application object, iterate it, and handle its output.
Method	`start`	Start the WSGI application in the threadpool.
Method	`startResponse`	The WSGI start_response callable. The given values are saved until they are needed to generate the response.
Method	`write`	The WSGI write callable returned by the start_response callable. The given bytes will be written to the response body, possibly flushing the status and headers first.
Instance Variable	`application`	The WSGI application object.
Instance Variable	`environ`	The WSGI environment `dict`.
Instance Variable	`headers`	A list of HTTP response headers supplied to the WSGI start_response callable by the application.
Instance Variable	`reactor`	An `IReactorThreads` provider which is used to call methods on the request in the I/O thread.
Instance Variable	`request`	The `http.Request` upon which the WSGI environment is based and to which the application's output will be sent.
Instance Variable	`started`	A `bool` indicating whether or not the response status and headers have been written to the request yet. This may only be read or written in the WSGI application thread.
Instance Variable	`status`	The HTTP response status `str` supplied to the WSGI start_response callable by the application.
Instance Variable	`threadpool`	A `ThreadPool` which is used to call the WSGI application object in a non-I/O thread.
Method	`_finished`	Record the end of the response generation for the request being serviced.
Method	`_sendResponseHeaders`	Set the response code and response headers on the request object, but do not flush them. The caller is responsible for doing a write in order for anything to actually be written out in response to the request.
Class Variable	`_log`	Undocumented
Instance Variable	`_requestFinished`	A flag which indicates whether it is possible to generate more response data or not. This is `False` until `http.Request.notifyFinish` tells us the request is done, then `True`.

def __init__(self, reactor, threadpool, application, request): (source) ¶

Undocumented

def run(self): (source) ¶

Call the WSGI application object, iterate it, and handle its output.

This must be called in a non-I/O thread (ie, a WSGI application thread).

def start(self): (source) ¶

Start the WSGI application in the threadpool.

This must be called in the I/O thread.

def startResponse(self, status, headers, excInfo=None): (source) ¶

The WSGI start_response callable. The given values are saved until they are needed to generate the response.

This will be called in a non-I/O thread.

def write(self, data): (source) ¶

The WSGI write callable returned by the start_response callable. The given bytes will be written to the response body, possibly flushing the status and headers first.

This will be called in a non-I/O thread.

application = (source) ¶

The WSGI application object.

environ = (source) ¶

The WSGI environment dict.

headers = (source) ¶

A list of HTTP response headers supplied to the WSGI start_response callable by the application.

reactor = (source) ¶

An IReactorThreads provider which is used to call methods on the request in the I/O thread.

request = (source) ¶

The http.Request upon which the WSGI environment is based and to which the application's output will be sent.

started: bool = (source) ¶

A bool indicating whether or not the response status and headers have been written to the request yet. This may only be read or written in the WSGI application thread.

status = (source) ¶

The HTTP response status str supplied to the WSGI start_response callable by the application.

threadpool = (source) ¶

A ThreadPool which is used to call the WSGI application object in a non-I/O thread.

def _finished(self, ignored): (source) ¶

Record the end of the response generation for the request being serviced.

def _sendResponseHeaders(self): (source) ¶

Set the response code and response headers on the request object, but do not flush them. The caller is responsible for doing a write in order for anything to actually be written out in response to the request.

This must be called in the I/O thread.

_log = (source) ¶

Undocumented

_requestFinished: bool = (source) ¶

A flag which indicates whether it is possible to generate more response data or not. This is False until http.Request.notifyFinish tells us the request is done, then True.
