nugitea

WORK IN PROGRESS

A very very minimal Gitea. No users, no roles, no login, no web UI — just a server that can clone, push, and mirror git repos, implemented by shelling out to git the same way Gitea itself does (verified against Gitea's actual source: routers/web/repo/githttp.go, modules/ssh/ssh.go, cmd/serv.go, modules/gitrepo/hooks.go, services/mirror/).

What it does

• Smart-HTTP clone/push (git clone http://host:3080/name.git) via git upload-pack/git receive-pack --stateless-rpc, same as Gitea's POST /info/refs, /git-upload-pack, /git-receive-pack endpoints.
• SSH clone/push (git clone ssh://host:2222/name.git) via a built-in SSH server that execs the same git subcommands directly against the session, mirroring Gitea's modules/ssh + cmd/serv.go.
• Git hooks: bare repos get pre-receive/update/post-receive delegator scripts that call back into nugitea hook <name>, mirroring Gitea's hook delegation — currently a no-op stub (no protected branches, no webhooks), a landing spot for future policy.
• Pull mirrors: periodically git fetch --prune --tags from a configured remote into a local bare repo.
• Push mirrors: periodically git push --mirror -f a local bare repo to a configured remote.

What it doesn't do

Everything else: no users, no authentication, no web UI, no issues/PRs, no webhooks, no LFS, no protected branches, no dumb-HTTP fallback, no AGit. All repos are fully open to clone and push. See internal/auth for the seam where real access control could be added later without touching the HTTP or SSH transport code.

Usage

go build -o nugitea ./cmd/nugitea

# Start the server (repos live under ./data by default)
./nugitea serve --http :3080 --ssh :2222 --repo-root ./data

# In another terminal:
./nugitea repo create demo
git clone http://localhost:3080/demo.git
git clone ssh://localhost:2222/demo.git   # port 2222 must be reachable as your ssh client's target

# Mirroring (flags must come before the positional args)
./nugitea mirror add-pull --interval 5m demo https://example.com/some/repo.git
./nugitea mirror add-push --interval 5m demo git@example.com:backup/demo.git

NUGITEA_REPO_ROOT sets the repo root for the repo/mirror subcommands when not passed --repo-root (only serve takes that flag directly; the other subcommands assume they're run against the same root as a running server).
