What did you do?

I used http2 to tunneling connexion between client and server (based on https://github.com/mmatczuk/go-http-tunnel project, with some change like used last version of goland http2). When client is based on aarch64 (I can't reproduce on x86_64 for now) and file to transfert size is medium size (~200ko) connexion is cut and I get "http2: stream closed". It's transfert only about first 129ko.

What did you expect to see?

Transfert file completly

What did you see instead?

Only first 129ko

Maybe it's just a buffer size to tweak for my usage but I'am not sure.

Thank in advance

For information if I revert to golang.org/x/net v0.0.0-20200324143707-d3edc9973b7e problem disapear

[andybons]

Can you post example code (preferably a minimal example)? d3edc9973b7e is the latest commit on x/net. When you say “revert” do you mean upgrade to use the latest x/net in the go distribution you’re using?
