Hi Sergey!
This is very cool! I'll be working to try this out as soon as I can.
One concern I have right now is about the new dependency on gvisor. Of
course you're not using it as the environment it was built for, but
nonetheless it is a pretty huge piece of software with quite a few
dependencies. And according to the FAQ [1] , it is only supported on
Linux on x86_64 (with "preliminary" support for arm64).
To try it out, I thought I'd build NNCP 8.2.0 on my Raspberry Pi: Linux,
but 32-bit. Didn't work:
PREFIX=/usr/local/nncp contrib/do all
do: Incremental mode. Use -c for clean rebuild.
do all
do bin/all
do bin/hjson-cli
do bin/nncp-bundle
# gvisor.dev/gvisor/pkg/tcpip/transport/tcp
vendor/gvisor.dev/gvisor/pkg/tcpip/transport/tcp/snd.go:326:16: constant 9223372036854775807 overflows int
That doesn't bode well.. It wouldn't surprise me at all if there are
other issues that would keep it from working on 32-bit platforms, or
non-Linux ones.
I don't know if there are other TCP implementations for Go that are
usable.
I'm sorry for asking for something that went in this direction - I
didn't quite realize what I was asking for, I guess. I'd much rather
have a uTP/TCP mismatch than sacrifice platform support in NNCP for
sure. I use ARM32 quite a bit around here, and actively with NNCP.
I do have NNCP 8.2.0 compiling on NetBSD, but whether it will work
correctly, or keep working over time given the gvisor FAQ, is another
question I guess (I don't have the environment to try that part yet).
