Overview

bjoern: Fast And Ultra-Lightweight HTTP/1.1 WSGI Server

Join the chat at https://gitter.im/jonashaag/bjoern

A screamingly fast, ultra-lightweight WSGI server for CPython 2 and CPython 3, written in C using Marc Lehmann's high performance libev event loop and Ryan Dahl's http-parser.

Why It's Cool

bjoern is the fastest, smallest and most lightweight WSGI server out there, featuring

  • ~ 1000 lines of C code
  • Memory footprint ~ 600KB
  • Python 2 and Python 3 support (thanks @yanghao!)
  • Single-threaded and without coroutines or other crap
  • Can bind to TCP host:port addresses and Unix sockets (thanks @k3d3!)
  • Full persistent connection ("keep-alive") support in both HTTP/1.0 and 1.1, including support for HTTP/1.1 chunked responses

Installation

pip install bjoern. See wiki for details.

Usage

Flask example

from flask import Flask

app = Flask(__name__)

@app.route("/")
def hello_world():
    return "Hello, World!"

if __name__ == "__main__":
    import bjoern

    bjoern.run(app, "127.0.0.1", 8000)

Advanced usage

# Bind to TCP host/port pair:
bjoern.run(wsgi_application, host, port)

# TCP host/port pair, enabling SO_REUSEPORT if available.
bjoern.run(wsgi_application, host, port, reuse_port=True)

# Bind to Unix socket:
bjoern.run(wsgi_application, 'unix:/path/to/socket')

# Bind to abstract Unix socket: (Linux only)
bjoern.run(wsgi_application, 'unix:@socket_name')

# Enable statsd metrics. See instrumentation.md for details.
bjoern.run(wsgi_application, host, port, statsd=...)

Alternatively, the mainloop can be run separately:

bjoern.listen(wsgi_application, host, port)
bjoern.run()

# With metrics. See instrumentation.md for details.
bjoern.listen(wsgi_application, host, port)
bjoern.run(statsd=...)

You can also simply pass a Python socket(-like) object. Note that you are responsible for initializing and cleaning up the socket in that case.

bjoern.server_run(socket_object, wsgi_application)
bjoern.server_run(filedescriptor_as_integer, wsgi_application)

# This needs manual compilation with `WANT_STATSD=yes`
bjoern.server_run(socket_object, wsgi_application, enable_statsd=True)
Issues
  • bjoern Python3 Port (tests/hello.py working)

    bjoern Python3 Port (tests/hello.py working)

    Introduced a single header file "py2py3.h" to handle python2/3 difference in bjoern and enable full python3 support on top of python2 support.

    This port heavily referenced the existing bjoern-py3 implementation: https://github.com/isaiah/bjoern-py3

    but removed the bytesio.c/h completely.

  • *BSD support?

    *BSD support?

    I trid to build this server from source on my FreeBSD8.2 system, but found a problem make this impossible. Error happened in the "server.c" file. Because BSD use libc as default, so the <sys/sendfile.h> include will go wrong( this file is a linux feature by glibc). In BSD,there is a sendfile() function works just the same as in the Linux but has few more parameters. The do_sendfile() function wrapped the sendfile() function in your code, so I think this make its easier to port to BSD. Thanks for your excellent job!!

  • #162: naïve implementation of 100-continue

    #162: naïve implementation of 100-continue

    This is my first Python C extension development experience, and frankly I don't work with C very often, but I thought this would be a fun way to practice.

    So if you have time and don't mind reviewing this, I would love to know what could be improved, etc.

    I didn't see a good way to implement option 2 in the PEP 3333 suggested mechanisms for handling Expect/Continue, so I went with option 1 (i.e., if Expect is encountered and the value is "100-continue", just go ahead and write it). It would probably be better to allow the client code to make this determination, but, although we could pass the client_fd as a PyFile to the client, it doesn't really have access to the header until the entire request is parsed, and by that time, it's too late. Please correct me if I'm wrong.

    Thanks!

  • Small step toward wheel

    Small step toward wheel

    Hi @jonashaag ,

    Here is a first step to build wheels as requested by #121. This PR is a small step : it does not change release process, does not change tests, does not add CI, does not support every binary platform.

    To upload wheel, you need docker-compose and twine. Then, simply run make upload. There is two new Make targets : distclean (just cleaning dist dir) and packages to build without uploading.

    $ make distclean packages
    ...
    $ tree dist/

    libev IS embedded in wheel. I'm wondering if this will trigger issue like with psycopg2 and libpq. The workaround is to use source tarball rather than wheel.

    Each wheel is pen tested in a virtualenv with test_wsgi_compliance.py.

    I hit a bug with cp27m. Instead of fighting this, I choose to blacklist it for now. Users will still use sources.

    The docker-compose.yml should be easy to translate to a CI job matrix, using either CircleCI, GitHub Action, Travis, Azure pipelines and/or appveyor.

    @jonashaag what do you think of this ?

    cpu 100% endless active loop on bjoern 1.4.2

    First of all - thanks for making this code - I find it really good approach to wsgi gateway. I wanted to give it a shot on pre-production new kind of service that I've launched recently - it's low latency rest endpoint.

    After some tests we find out that bjoern falls in active wait on epool (monitored with strace), but still handling requests right. I assume it's a bug because falling back to uwsgi solved this problem.

    launched with reuse_port, like this: bjoern.run(wsgi.application, 'localhost', 8000, reuse_port=True)

    My question is what kind of input do You need to debug?

  • Fixed client accepting flow

    Fixed client accepting flow

    I am currently working on a platform that uses the microservice architecture and I am testing the use of bjoern as http server for our microservices. Our microservices are behind envoy proxy and under high stress I get timeouts for about 5% of the connections.

    It seems to be a bjoern issue with the "keep-alive" flow.

    Current behavior in bjoern:

    • From time to time, after a request is served on a keep-alive connection, the new request triggers the accept_watcher/ev_io_on_request which puts bjoern in "accept mode", therefore the previous connection is terminated.

    Implemented behavior:

    • After a new client is accepted, the accept_watcher is disabled. The watcher is enabled again only on the close_connection use case.

    This has been tested with the version 3.0.1.

    Bjoern Installation Fails on Mac OS X 10.6 w/ Homebrew, Xcode 4

    Interestingly enough, a fresh install still produces errors. The process:

    1. Install Mac OS X 10.6.
    2. Install Xcode 4 Build 4A225.
    3. Install latest Python 2.7 from .pkg installer.
    4. Install homebrew and run: brew install libev
    5. Install virtualenv for 2.7, create a new environment, and enter it.
    6. Run: pip install bjoern

    The pip.log is: http://dpaste.de/wDGo/

    Again it seems like I'm dealing with architecture (x86 vs. x64) issues. I'll have to see if there's a way to make brew install universal (dual 32-bit and 64-bit) versions.

    Add statsd metrics on server events

    I've added metrics wherever they made sense to me, these are all simple increment metrics counting the number of times an event happened.

    There is scope for gauge and timer too but I'm not sure those will be as helpful inside bjoern, almost all of these can also be exposed from the WSGI app.

    I don't write C a lot so please feel free to suggest code design changes.

    Installation fails on Mac OS X 10.6.

    Python 2.7, latest Snow Leopard, libev 3.9 installed via ports. Installed via:

    sudo port install libev virtualenv --no-site-packages --distribute sandbox cd sandbox ; . bin/activate pip install bjoern

    The result is that ev.h can't be found and thus a whole slew of errors and warnings are displayed. The version of Python, operating system, and the exact errors/warnings I believe are irrelevant to this problem; ports likely installed libev in /usr/local instead of /usr.

    How would I tell pip (or, if I clone the repo, setup.py) to check a different location for includes/libraries?

  • Is there a way to set timeouts?

    Is there a way to set timeouts?

    I just started using bjoern on my project and it's been going great so far. What I'd like to know is if there's a way to globally set a timeout for requests.

    My project is a very simple API with a few endpoints, but sometimes the request will take too long and I'd like to set a timeout for all endpoints

    the code looks something like this:

    from flask import Flask
    
    app = Flask(__name__)
    host = "0.0.0.0"
    port = 5000
    
    @app.route("/up", methods=["POST"])
    def up():
        res = doSomething()
        return(res)
    
    @app.route("/down", methods=["POST"])
    def down():
        res = doSomethingElse()
        return(res)
    
    if __name__ == "__main__":
        import bjoern
        bjoern.run(app, host, port)
    

    what I'd like to happen is to end the connection if either /up or /down takes more than 20s. is that possible?
