Helper for WSGIResource
which drives the WSGI application using a threadpool and hooks it up to the
http.Request
.
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 | reactor | An IReactorThreads
provider which is used to call methods on the request in the I/O thread. |
Instance Variable | threadpool | A ThreadPool
which is used to call the WSGI application object in a non-I/O thread. |
Instance Variable | application | The WSGI application object. |
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 | environ | The WSGI environment dict . |
Instance Variable | status | The HTTP response status str
supplied to the WSGI start_response callable by the application. |
Instance Variable | headers | A list of HTTP response headers supplied to the WSGI start_response callable by the application. |
Method | __init__ | Undocumented |
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. |
Method | start | Start the WSGI application in the threadpool. |
Method | run | Call the WSGI application object, iterate it, and handle its output. |
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 . |
Method | _finished | Record the end of the response generation for the request being serviced. |
Method | _sendResponseHeaders | No summary |
bool

application thread.
IReactorThreads
provider which is used to call methods on the request in the I/O thread.
http.Request
upon which the WSGI environment is based and to which the application's
output will be sent.
str
supplied to the WSGI start_response callable by the application.
False
until http.Request.notifyFinish
tells us the request is done, then True
.
Record the end of the response generation for the request being serviced.
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.
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.
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.
Start the WSGI application in the threadpool.
This must be called in the I/O thread.
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).
