Future support for HTTP/3?

[NovaAndrom3da]

Is HTTP/3 in the roadmap for waitress? Or has someone done this on a fork? Any help would be much appreciated.

Until there are good libraries available for it in Python, it is unlikely that Waitress will support it. As it currently stands HTTP/3 is not yet standardized and is a rapidly changing target.

Could this be somehow acieved using (iirc) the AIOQUIC module?

No, waitress is not based on asyncio or modern async/await paradigm, but on predecessor module asynchat.

I've spent some time looking at replacing the existing asyncore based setup with async/await with asyncio, however the current way of doing IO is deeply integrated into the way waitress works and operates. There is no good abstraction to easily replace, and would require a large rewrite.

I also don't expect there to be a lot to gain making that change.

Adding external libraries like aioquic means that it is also no longer a pure Python web server, as it relies on C extensions and having OpenSSL available to compile against, if there is no wheel for the platform...

If having HTTP/3 in Waitress is a requirement, I'd recommend forking this project. It is unlikely that I will accept the additional complexity and changes necessary to make it work in this current code base.
