Useful information about testing v2 protocol:
https://docs.gitlab.com/ee/administration/git_protocol.html
For ssh you should allow env variable in sshd conf as mentioned above. It works, tried with docker container.
Https downgrades to v1 protocol on server side. Something with the headers i suppose

Hi once again. There's a branch for support git protocol v2 for gitlab:
https://gitlab.com/gitlab-org/gitaly/merge_requests/844/diffs
So basic idea for http support as it seems is:

1. Receive header from client
2. Put it into a variable
3. Pass it to git
4. ?

I'm not a GO developer but out of curiosity I've checked gitea sources and it seems to me that such behaviour could be implemented in routers/repo/http.go
Anyway gitlab is very helpful. Thanks to them.

So, does current version support git v2 protocal?

Could we list the lack of Git Wire Protocol, Version 2 support in the comparison page (https://docs.gitea.io/en-us/comparison/)?

@NLZ please send a PR

We already support git wire protocol version 2. Closing this as complete.
