Screaming-fast Python 3.5+ HTTP toolkit integrated with pipelining HTTP server based on uvloop and picohttpparser.

Overview

Japronto!

irc: #japronto Gitter japronto/Lobby Build Status PyPI PyPI version

There is no new project development happening at the moment, but it's not abandoned either. Pull requests and new maintainers are welcome.

If you are a novice Python programmer, you don't like plumbing yourself or you don't have basic understanding of C, this project is not probably what you are looking for.

Japronto (from Portuguese "já pronto" /ˈʒa pɾõtu/ meaning "already done") is a screaming-fast, scalable, asynchronous Python 3.5+ HTTP toolkit integrated with pipelining HTTP server based on uvloop and picohttpparser. It's targeted at speed enthusiasts, people who like plumbing and early adopters.

You can read more in the release announcement on medium

Performance

Here's a chart to help you imagine what kind of things you can do with Japronto:

Requests per second

As user @heppu points out Go’s stdlib HTTP server can be 12% faster than the graph shows when written more carefully. Also there is the awesome fasthttp server for Go that apparently is only 18% slower than Japronto in this particular benchmark. Awesome! For details see https://github.com/squeaky-pl/japronto/pull/12 and https://github.com/squeaky-pl/japronto/pull/14.

These results of a simple "Hello world" application were obtained on AWS c4.2xlarge instance. To be fair all the contestants (including Go) were running single worker process. Servers were load tested using wrk with 1 thread, 100 connections and 24 simultaneous (pipelined) requests per connection (cumulative parallelism of 2400 requests).

The source code for the benchmark can be found in benchmarks directory.

The server is written in hand tweaked C trying to take advantage of modern CPUs. It relies on picohttpparser for header & chunked-encoding parsing while uvloop provides asynchronous I/O. It also tries to save up on system calls by combining writes together when possible.

Early preview

This is an early preview with alpha quality implementation. APIs are provisional meaning that they will change between versions and more testing is needed. Don't use it for anything serious for now and definitely don't use it in production. Please try it though and report back feedback. If you are shopping for your next project's framework I would recommend Sanic.

At the moment the work is focused on CPython but I have PyPy on my radar, though I am not gonna look into it until PyPy reaches 3.5 compatibility somewhere later this year and most known JIT regressions are removed.

Hello world

Here is how a simple web application looks like in Japronto:

from japronto import Application


def hello(request):
    return request.Response(text='Hello world!')


app = Application()
app.router.add_route('/', hello)
app.run(debug=True)

    Installing fails on OSX

    There is no requirements.txt and installation fails:

    $ python3 setup.py install

    Installing this way should install the dependencies.

    CPU hits illegal instruction signal on older hardware

    I installed Japronto on OSX via setup.py, and attempted to run the hello world example. The example threw an error when I tried to connect to it via my browser or wrk. The error message was

    Worker exited with code -4!

    Note: I am using a 2010 Macbook pro with Sierra, and received this error straight from the fresh git clone. The installation ran fine but I received a few warnings about uvloop.

  • connection_made errors out with latest uvloop.

    connection_made errors out with latest uvloop.

    I tried a very basic tutorial at https://github.com/squeaky-pl/japronto/blob/master/tutorial/1_hello.md with pip 10.0.1, japronto 0.1.1, uvloop 0.9.1, and ujson 1.35 on Ubuntu 18.04 64-bit running Python 3.6.5. I have tried the latest Sanic with this uvloop and it doesn't cause any errors with it.

    When I start the server, it instantly shows this in the terminal:
    Accepting connections on http://0.0.0.0:8080

    but when I go to that in my browser, the browser is stuck in a loading animation and it immediately errors out in the terminal with this output:

    Exception in callback UVTransport._call_connection_made
    handle: <Handle UVTransport._call_connection_made>

    I know this project hasn't been maintained in a while, but a bunch of benchmarking sites like https://github.com/tbrand/which_is_the_fastest are starting to list it as the best Python server competing with Rust, Go, and Node.

    Will there be updates to this in the near future and if so, will there be more testing?

  • Using Python-Kafka with Japronto

    Using Python-Kafka with Japronto

    I really didn't understand what is causing the issue here. I have initialised producer like below. But when we call the request is failing. But the same thing if we execute in terminal or same structured code in Sanic is working fine.

    Any ideas or suggestions to fix this?

    def visuG(request):
    	print(producer.config)
    	print(producer)
    	jstore = request.json
    	print(jstore)	
    	jevents = json.loads(jstore['e'])
    	print(jevents)
    	raw_data = {'topic': 'vnk-desd', 'routes': 'clst/desd', 'messages': jevents}
    	f = producer.send("vnk-raw", raw_data)
    	print(f)
    	r = f.get(timeout=1)
    	return request.Response(code=200,json=r)
    
    
    app = Application()
    
    
    # The Router instance lets you register your handlers and execute
    # them depending on the url path and methods
    r = app.router
    r.add_route('/user-activity-poc', visuG, methods=["POST"])
    r.add_route('/spcb', visuG, methods=["POST"])
    
    # Finally start our server and handle requests until termination is
    # requested. Enabling debug lets you see request logs and stack traces.
    app.run(debug=True)
    

    Error

    I don't think it is because of timeout as I tried it with 10 seconds. It didn't work. Any ideas it is failing ?

    Need suggestions to work with motor (MongoDB async driver)

    My app structure (simplified):

    manage.py
    

    app/__init__.py

    from japronto import Application
    from motor.motor_asyncio
    
    client = motor.motor_asyncio.AsyncIOMotorClient()
    db = client.mydb
    
    async def index(request):
        result = await db.find_one()
        print(result)
        return request.Response(text=str(result), mime_type='text/html')
    
    def create_app():
       app = Application()
       app.router.add_route('/', index)

    from app import create_app
    
    if __name__ == '__main__':
       app = create_app()
       app.run(debug=True)
    
    

    When I ran it, I got an exception:

    RuntimeError: Task <Task pending coro=<pkg() running at  .../app/__init__.py:64> cb=[Pipeline._task_done()]> got Future <Future pending cb=[_chain_future.<locals>._call_check_cancel() at /miniconda/envs/flecom/lib/python3.6/asyncio/futures.py:407]> attached to a different loop
    

    I suspect putting client = motor.motor_asyncio.AsyncIOMotorClient() inside index would work, but that would create new connections for every request. Reusing connection would be more preferable.

    A risk of writing to an invalid address with memcpy in function Parser_feed

    Code snippet

    Parser_feed(Parser* self, PyObject *args)
    {
         ........
         if((size_t)data_len > self->buffer_capacity - (self->buffer_end - self->buffer_start)) {
                self->buffer_capacity = MAX(self->buffer_capacity * 2, self->buffer_end - self->buffer_start + data_len);
                if(self->buffer == self->inline_buffer) {
                       self->buffer = malloc(self->buffer_capacity);    --------> may return a NULL pointer
                       memcpy(self->buffer + self->buffer_start, self->inline_buffer + self->buffer_start,
                                      self->buffer_end - self->buffer_start);
        } 
        ........
    }
    

    Description

    Function: Parser_feed File: cparser.c Call-path: feed (Python) -> Parser_feed -> memcpy WarningType: Invalid write. Our analysis tool reported a warning on potential write at an invalid address. As the buffer_capacity may depend on external inputs, hence it is possible that malloc-fail happens. Return value validation is necessary at this point. Also seen in Details

    thank you

    I thank your team The latest version is a year old and I'm surprised by the performance of Japronto, but are you not updating it and also is it possible to communicate with neo4j ? japronto and neo4j are best .
