locust support testing against HTTP/2 servers ?

[centminmod]

Any plans for Locust to support testing against HTTP/2 servers like h2o https://github.com/h2o/h2o and OpenLiteSpeed http://open.litespeedtech.com/mediawiki/ ?

cheers

We found that the Hyper could support the HTTP/2.
https://github.com/Lukasa/hyper
http://hyper.readthedocs.org/en/development/quickstart.html#requests-integration

Now we are trying to integrate the HTTP/2 into Locust, we were wondering that any kinds of suggestions about how to integrate the Hyper into Locust?

Look forward to you reply.

Thank you,
Ken

Locust support http2?

[cgoldberg]

yes, if you use an http2 client within your locust scripts

is there any example to implement hyper for http/2 client on locust ?

Thanks

Hi!

I managed to make it work with httpx (which use hyper under the hood). It's mostly compatible with requests https://www.python-httpx.org/compatibility/

Check my gist. You just have to use the HttpxUser in your locustfile https://gist.github.com/gawel/f48e577425f872e1a81028f3f53353cf#file-clientx-py-L216

Let me know if you're interested in a PR to add this in contrib/httpx (of course I'll add some tests). If not I'll probably create a dedicated package

[gawel]

I've also found a way using @Kenith sugestion:

from locust import TaskSet, between, HttpUser
from hyper.contrib import HTTP20Adapter

class Http2User(HttpUser):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.client.mount(self.host, HTTP20Adapter())

Don't know which one is the more efficient but this second option is easy to use

@gawel note that httpx relies on hyper-h2 (the HTTP/2 protocol stack) rather than hyper, the client (which I myself got confused about, see: encode/httpx#1476). The later is deprecated in favor of httpx. That means the HTTP20Adapter (which came with the client) shouldn't be used in new code, but FWIU, httpx aims to be very compatible with requests, so that might not be a problem.
