HTTP/2

[s-celles]

Hi,

Is there some work here to support HTTP/2?
I noticed https://github.com/sorpaas/HTTP2.jl/ seems to be abandonned
and have been removed from General Registry.

Kind regards

PS: wondering that while working on https://github.com/s-celles/gRPCServer.jl/tree/develop

Ref: sorpaas/HTTP2.jl#6

Yes, there's #1213, which switches the internal implementation to use the aws-c-http C library, which has native support for HTTP/2. The PR works, but there's a long-tail of compatibility things I've had a hard time finding the time to dig into. I think the biggest piece is HTTP.open mode where you can stream write/read, that I initially thought maybe we could break with a 2.0 release, but I've since come to think is a non-negotiable to have (too many use-cases that rely on streaming).

Getting this in is pretty high up on my TODO list, just been tied up in a lot of stuff lately.

Hi @quinnj

Just to let you know that I have been working on https://github.com/s-celles/Nghttp2Wrapper.jl (a Julia wrapper for nghttp2 C library).

Do you think it can help?

Work in Progress about HTTP/2 support for Julia as standalone package can be found here

• https://github.com/s-celles/Nghttp2Wrapper.jl (through nghttp2 C library)
• https://github.com/s-celles/PureHTTP2.jl/ (using pure Julia)

My idea is that PureHTTP2.jl will use Nghttp2Wrapper for integration tests.

My work on HTTP/2 is in #1248; I have it deployed in production for a few projects and it's working well. The last piece was cleaning up the 1.0 -> 2.0 migration story and possibly massaging some of the breaking changes so they're less breaking.

(this is a new PR that supercedes the earlier mentioned approach of wrapping aws CRT libraries; this is, instead, a pure Julia approach based on the new pure-Julia Reseau.jl package which is a libuv-independent low-level IO implementation for network operations)

Interesting... Didn't know your work on https://github.com/JuliaServices/Reseau.jl

I feel we will have many HTTP/2 solutions!

Thanks

I need to have "production ready" HTTP/2 support in Julia for gRPCServer.jl which will be needed by Pulumi.jl https://github.com/s-celles/Pulumi.jl (currently WIP... but quite usable)
