git-receive-pack error

[ceremcem]

I have a dedicated git repo backed by GOGS, which is served behind Nginx proxy and has an url like https://example.com/git, so the repo bar under user foo is named as https://example.com/git/foo/bar.

My git-cache-http-server setup works correctly for Github but not for my dedicated server. What is git-receive-pack error? How can I workaround this?

The error I've got from the failing git repo is like so:

fatal: unable to access 'http://gitcache:8080/example/git/foo/bar.git/': The requested URL returned error: 500

Systemctl status is as follows:

I'm not sure what's going on, other than the client (I think) is trying to use one variant of the protocol we don't yet support. From a quick read of the current protocol docs, I can't immediately see why it's trying to use git-receive-pack on one server, but not on the other.

I think I'll need to reproduce the issue locally to understand it. I'll try to do this in the next few days.

[ceremcem]

Is it a possibility that GOGS does use git-receive-pack forcefully? So might it be a GOGS related setting?

[jonasmalacofilho]

@ceremcem I'm sorry that I still haven't looked into this.

Can you give me access to a copy of the repository where this happens?

[ceremcem]

I've e-mailed the login credentials just now. I experienced that problem with any repository in my server, so any trivial repo should give the same error.

[jonasmalacofilho]

I was able to reproduce the git-receive-pack calls (even though I wasn't yet testing the cache) on both your Gogs instance and GitHub. So it's easier to just add support for it...

Can you by any chance look into that?

(I'm still curious as to why the problem didn't happen before with GitHub, but I don't think there's much point investigating into it now)

[ceremcem]

Any updates?

[jonasmalacofilho]

I checked the protocol specification (and its implementation in git) and the git-receive-pack service should only be requested for a push.

The current version of the project only supports clone and fetch. I started to port the project to Rust, and was going to add support for push/git-receive-pack in the new version, but other things happened and it's still far from ready...
