Stats

Sanic is a Python 3.6+ web server and web framework that's written to go fast. It allows the usage of the async/await syntax added in Python 3.5, which makes your code non-blocking and speedy.

Sanic is also ASGI compliant, so you can deploy it with an alternative ASGI webserver.

Source code on GitHub | Help and discussion board.

The project is maintained by the community, for the community. Contributions are welcome!

The goal of the project is to provide a simple way to get up and running a highly performant HTTP server that is easy to build, to expand, and ultimately to scale.

Installation

pip3 install sanic

Sanic makes use of uvloop and ujson to help with performance. If you do not want to use those packages, simply add an environmental variable SANIC_NO_UVLOOP=true or SANIC_NO_UJSON=true at install time.
$ export SANIC_NO_UVLOOP=true
$ export SANIC_NO_UJSON=true
$ pip3 install --no-binary :all: sanic

Note

If you are running on a clean install of Fedora 28 or above, please make sure you have the redhat-rpm-config package installed in case if you want to use sanic with ujson dependency.

Note

Windows support is currently "experimental" and on a best-effort basis. Multiple workers are also not currently supported on Windows (see Issue #1517), but setting workers=1 should launch the server successfully.

Hello World Example

from sanic import Sanic
from sanic.response import json

app = Sanic()

@app.route('/')
async def test(request):
    return json({'hello': 'world'})

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=8000)

Sanic can now be easily run using sanic hello.app.

[2018-12-30 11:37:41 +0200] [13564] [INFO] Starting worker [13564]

And, we can verify it is working: curl localhost:8000 -i

HTTP/1.1 200 OK
Connection: keep-alive
Keep-Alive: 5
Content-Length: 17
Content-Type: application/json

{"hello":"world"}

Now, let's go build something fast!

New release on Pypi ?

Hello,

I was looking for a tool to autoreload my code when I develop and I found this commit : https://github.com/channelcat/sanic/commit/52c2a8484e6aa5fa13aaade49e1f2597dd006e15

So it seems Sanic already integrates it since December 07, 2017. But the the latest version on Pypi dates from the day before (https://github.com/channelcat/sanic/commit/1ea3ab7fe8ab03a6ddf4d75a3de8cb719f4c584c) : https://pypi.org/project/Sanic/#history

Is-it possible to release a new version on Pypi please ? Other features (like the UUID support in routes) are also interesting :)

Thanks in advance !

New websockets

Resolves #2000

@aaugustin @ahopkins I've spent another couple of days on it, and its now passing all of the tests, including some other demo applications I've written to stress it out.

It certainly needs cleaning up, and could probably get some efficiency improvements in places too, but otherwise I'm pretty happy with it.

This branch also incorporates another change I've written, that splits the existing server.HttpProtocol out into a base SanicProtocol class, that contains just all of the connection-handling and transport-layer stuff, and HttpProtocol that is a subclass of SanicProtocol and adds the HTTP-specific handlers on top of that. I'd like the new WebSocketProtocol to subclass SanicProtocol but for now it still subclasses HttpProtocol.

ASGI refactoring attempt
This isn't intended to be graceful at this point, rather just to make a start on getting passing tests, using an ASGI-based app, connected to an ASGI-based test client.

The application changes are intended to be the dumbest possible thing that could provide the ASGI interface, with the intention that once the test suite was passing or sufficiently passing, then refactoring towards something far more graceful could start.

There are two changes:

The Sanic class has an ASGI based __call__ interface, that calls into a dumb shim layer.

The SanicTestClient is replaced from an aiohttp client that makes actual network requests, into a requests based client, that has an adapter to make ASGI requests direct to the application.

Because the requests interface differs in places to the aiohttp client interface, there's a bit of fiddling around to ensure that API compatibility. Again, this is just the dumbest possible place to start, with a view to moving to something more graceful later.

Nicer error handling after eof, warning for second response being created
Trying to solve issue: https://github.com/sanic-org/sanic/issues/2219

Some doubts I still have:

Whether it's okay to put a response reference in request instance. I recently learned from the memory leak issue; we should not create more reference if not necessary. I am considering replace it with a bool flag.

Should we only allow one response instance for each request? If so, we can consider keep and cache the response reference and return it if request.respond method is called more than 1 time.

I believe that self.response_func is None and self.stage == Stage.IDLE implies the request has been responded and the response stream is ended. Am I correct on this?

Please let me know your suggestions, thanks! @sanic-org/core-devs

Unicode character parsing

Per #539 there may be a continued problem in parsing unicode characters due to a dependency.

Per @vltr: /中国 or even /jacaré would break on request.py, mostly because of httptools.parse_url that receives bytes and is unable to parse non-ascii chars. I'll need to dig deeper to see if this is a restraint in httptools itself or just in the Python bindings.

Doc rework

In reference to https://github.com/huge-success/sanic/issues/1691 I have moved all markdown docs to rst. The discussion over why we went for rst vs md can be seen in full in the issue chat.

There is a minor bug with the table in the configuration page where the top row doesn't seem to have splits, but I am not sure if that is a rst "feature" vs an actual bug. Also, the routing on the left nav bar for some reason seems to be broken and I am unsure as to why.

I ran a tox check but it skipped due to win32 not in list There are a large number of errors when I build it with sphinx, but those are to do with api_reference and _sanic which are files I have not touched, nor understand.

Templates support
What do you think about integrate templates (jinja2?) into sanic core? I think the popularity of django and flask largely depends on their ability to write and distribute independent apps, which contains its own routes, handlers, templates and static files. Sanic has all of this except of templates.

If you agree, I suggest the next api:

render_string('index.html', context) render('index.html', context) @app.context_processor @bp.context_processor @app.template('index.html') @bp.template('index.html')

EDIT: To elaborate, it should be documented that although add_route and routes can add routes with/without trailing slashes, remove_routes has no behavior to account for that.

Call For Contributors - Discussion

Sanic Web Framework - Call for Contributors

While some industry analysts have observed an increase in activity on open source projects during the current pandemic, unfortunately that is not the case for all open source projects.

Since its initial public release in 2016, the Sanic Web Framework has had several waves of interest and short bursts of contribution activity, with just a handful of dedicated long-term contributors forming a core-contributors group.

In January 2020 the Sanic organization announced a new Organization Structure adopting a PEP-8016 model including electing a new Release-Managers team, a new Steering-Council, and writing our S.C.O.P.E.

Unfortunately since March 2020, both of our release managers, two of the steering council members, and three core contributors have left the project due to pressures from the pandemic and other commitments. While we're disappointed to see them leave, we wish them and their families well and all the best in their future endeavors.

The Sanic Web Framework is more popular now than ever, with thousands of downloads from PyPI daily, Sanic is used in almost 3500 other open source projects on GitHub.

The steering council has made a decision to put out a call for contributors. Sanic is a project of, and a product of, the community; everyone has a voice and the ability to help make decisions. The goal of the Sanic project is to be community built. The strength and direction of the project is decision by consensus as laid out in the S.C.O.P.E.

Doesn't matter if you have a masters in computer science, are a senior software engineer, an intern, or are a high school student. The great thing about open source is anybody can contribute.

Where can I chat to the team about this?

We have a pretty active Community Forum as well as the Gitter chatroom. If you prefer to use Github, you can reply to this issue.

Why should I contribute? I don't know how to contribute! What can I even offer?

Working on a bleeding edge web framework is excellent material for your resume and you learn a lot. Many of us got awesome jobs because of our open source commitments. See the Opensource Guide's article on Why Contribute to Open Source?

TL;DR?

A large portion of the contributors to the Sanic project are no longer able to help, we need your help.

Socket binding implemented properly for IPv6 and UNIX sockets.
app.run("::1") for IPv6

~~app.run("unix:/tmp/server.sock")~~ app.run(unix="/tmp/server.sock") for UNIX sockets

app.run("localhost") retains old functionality (randomly either IPv4 or IPv6, or with workers=1 might be both)

Do note that IPv6 and UNIX sockets are not fully supported by other Sanic facilities. In particular, request.server_name and request.server_port are currently unreliable.

Blueprint Middleware runs before App Middleware
Is there an existing issue for this?

[X] I have searched the existing issues

Describe the bug

With the code below, the bp middleware runs before the app/global middleware. Can you explain why?

I expected the middleware to be registered on app level and the bp middleware on bp level such that the app middleware is always executed first and the bp middleware as soon as the bp is "entered" on a request.

I know that this is theoretically solved by adding priority, but this behavior is not mentioned in the docs and feels like a bug because it contradicts intuition of data flow and locality.

Related Issue: #2636

Code snippet

from sanic import Sanic, Blueprint, text bp = Blueprint('test') @bp.get('/') def hello_world(request): return text("Hello World") @bp.on_request def bp_middleware(request): print("Blueprint Middleware") app = Sanic(__name__) @app.on_request def app_middleware(request): print("App Middleware") app.blueprint(bp) if __name__ == '__main__': app.run("localhost", port=8000, debug=True, dev=True, auto_reload=True)

Expected the app middleware to wrap the bp middleware

Sanic closes connection prematurely
Is there an existing issue for this?

[X] I have searched the existing issues

Describe the bug

When a client downloads data slowly from a Sanic server, Sanic terminates the connection before all data has been downloaded. Specifically, the connection is terminated before all of the data specified by the content-length header has been downloaded.

I previously raised this as #2613, but that was closed. I'm raising this again because I'm pretty sure this is a bug.

Code snippet

Run the following Sanic server:

from sanic import Sanic from sanic.response import raw app = Sanic("MyHelloWorldApp") app.config.REQUEST_TIMEOUT = 2000 app.config.RESPONSE_TIMEOUT = 2000 @app.get("/foo") async def foo_handler(request): print(f"HEADERS: {request.headers}") data = bytearray(500 * 1024 * 1024) return raw(data) if __name__ == "__main__": app.run(debug=True)

In a separate process, run this client application:

from time import sleep import requests import logging logging.basicConfig(level=logging.DEBUG) url = 'http://127.0.0.1:8000/foo' s = requests.Session() r = s.get(url, stream=True) content_length = int(r.headers["content-length"]) print(f"Content length: {content_length}") total = 0 for chunk in r.iter_content(chunk_size=1024 * 1024): total += len(chunk) sleep(0.1) print(f"Total downloaded: {total}") assert total == content_length, f"Expected {content_length} bytes, but got {total} bytes"

Expected Behavior

I would expect the amount of data specified by the content-length header to be downloaded. However, the client fails with an error like this:

AssertionError: Expected 524288000 bytes, but got 222742503 bytes

Note that the amount of data downloaded is not always the same, but is reliably less than the length specified by the content-length header on my machine.

A Wireshark capture appears to show the server sending a FIN while the client is still downloading data.

How do you run Sanic?

As a script (app.run or Sanic.serve)

Operating System

Mac OS 12.2.1 (also appears to happen on Linux in our production system)

Sanic Version

22.9.1 (also tried 21.12.1 and it happens there too)

Additional context

This does not happen on the old version of Sanic we were using previously (19.12.5).

The behaviour can be changed, but not solved, by changing Sanic's KEEP_ALIVE_TIMEOUT to a larger value. However, it's still possible to reproduce the issue by downloading the data slightly more slowly. For example setting KEEP_ALIVE_TIMEOUT to 75 seconds, and the sleep time in the client to 0.5 seconds still reproduces the issue.

#2378 Introduce HTTP/3 and autogeneration of TLS certificates in DEBUG mode

👶 EARLY RELEASE FEATURE: Serving Sanic over HTTP/3 is an early release feature. It does not yet fully cover the HTTP/3 spec, but instead aims for feature parity with Sanic's existing HTTP/1.1 server. Websockets, WebTransport, push responses are examples of some features not yet implemented.

📦 EXTRA REQUIREMENT: Not all HTTP clients are capable of interfacing with HTTP/3 servers. You may need to install a HTTP/3 capable client.

📦 EXTRA REQUIREMENT: In order to use TLS autogeneration, you must install either mkcert or trustme.

Version 22.3.0

Features

#2347 API for multi-application server

🚨 BREAKING CHANGE: The old sanic.worker.GunicornWorker has been removed. To run Sanic with gunicorn, you should use it thru uvicorn as described in their docs.

🧁 SIDE EFFECT: Named background tasks are now supported, even in Python 3.7

#2357 Parse Authorization header as Request.credentials

#2361 Add config option to skip Touchup step in application startup

#2372 Updates to CLI help messaging

#2382 Downgrade warnings to backwater debug messages

#2396 Allow for multidict v0.6

#2401 Upgrade CLI catching for alternative application run types

#2402 Conditionally inject CLI arguments into factory

#2413 Add new start and stop event listeners to reloader process

#2414 Remove loop as required listener arg

#2415 Better exception for bad URL parsing

sanic-routing#47 Add a new extention parameter type: <file:ext>, <file:ext=jpg>, <file:ext=jpg|png|gif|svg>, <file=int:ext>, <file=int:ext=jpg|png|gif|svg>, <file=float:ext=tar.gz>

👶 BETA FEATURE: This feature will not work with path type matching, and is being released as a beta feature only.

sanic-routing#57 Change register_pattern to accept a str or Pattern

sanic-routing#58 Default matching on non-empty strings only, and new strorempty pattern type

🚨 BREAKING CHANGE: Previously a route with a dynamic string parameter (/<foo> or /<foo:str>) would match on any string, including empty strings. It will now only match a non-empty string. To retain the old behavior, you should use the new parameter type: /<foo:strorempty>.

Bugfixes

#2373 Remove error_logger on websockets

#2381 Fix newly assigned None in task registry

sanic-routing#52 Add type casting to regex route matching

sanic-routing#60 Add requirements check on regex routes (this resolves, for example, multiple static directories with differing host values)

Deprecations and Removals

#2362 22.3 Deprecations and changes

debug=True and --debug do NOT automatically run auto_reload

Default error render is with plain text (browsers still get HTML by default because auto looks at headers)

config is required for ErrorHandler.finalize

ErrorHandler.lookup requires two positional args

Unused websocket protocol args removed

#2344 Deprecate loading of lowercase environment variables

Developer infrastructure

#2363 Revert code coverage back to Codecov
