-----------------------------------
Attachment: thrift-1848-python-async-server-v2.patch
> Python asynchronous server
> --------------------------
>
> Key: THRIFT-1848
> URL: https://issues.apache.org/jira/browse/THRIFT-1848
> Project: Thrift
> Issue Type: New Feature
> Components: Python - Compiler, Python - Library
> Affects Versions: 1.0, 1.1, 1.2
> Reporter: Piotr Nowojski
> Attachments: thrift-1848-python-async-server.patch,

> As far as I know, there is no support in python for anything else, then
> blocking communication/non-blocking/twisted. Non-blocking is not
> asynchronous and we definitely don't want to use twisted. I'm really
> interested in adding support for onCompleted/onError callbacks model.
> After small research, I've found couple of discussions/complains about
> missing such functionality.
> The main idea is to allow users (for example my project in my company...) to
> create single threaded thrift servers, with one thread processing all thrift
> requests AND user created events. Support for custom events (and events loop)
> is done, by adding support for "step()" method in WorkerAsync(), which is
> being
> called at least once a given timeout. Example code is in the tutorial
> py.async.
> I have added "sleep(duration)" command to the py.async PythonServer which is
> being invoked on PythonClient, which sleeps for given number of seconds (1.5
> in PythonClient).
> console1: ./PythonServer.py
> console2: for i in {1..100}; do ./PythonClient.py & done
> Second console will complete within ~2 seconds with only one thread on the
> server. On TSimpleServer, TNonblockingServer or TThreadPoolServer with about
> 10 threads, it would take much more time to complete.
