Fintan Halpenny 694bd345d9 node: use ls-remote when in fetching mode
Given the scenario of 3 peers, A, B, and C each having a project R. If
peer A has B's fork, but C does not, then when peer A attempts to
fetch from C the fetch will be rejected since Git will fail when a
refspec that is asked for does not exist on the remote side.

To avoid this, the fetch logic is changed so that the client first calls
ls-remote to the remote side, which results in the references that the
remote has which the client is interested in. The follow-up fetch then
uses these refs as the refspecs -- which should succeed unless there
was a race for a deletion on the remote side.

The rest of the verification logic stays the same, so the storage
should still be in a working state before transferring from the staged
repository to the production repository.

Radicle Heartwood Protocol & Stack

Heartwood is the third iteration of the Radicle Protocol, a powerful peer-to-peer code collaboration and publishing stack. The repository contains a full implemention of Heartwood, complete with a user-friendly command-line interface (rad) and network daemon (radicle-node).

Radicle was designed to be a secure, decentralized and powerful alternative to code forges such as GitHub and GitLab that preserves user sovereignty and freedom.

Installation

Requirements

  • Linux or Unix based operating system.
  • Git 2.34 or later
  • OpenSSH 9.1 or later with ssh-agent

📦 From source

Requires the Rust toolchain.

You can install the Radicle stack from source, by running the following commands from inside this repository:

cargo install --path radicle-cli --force --locked
cargo install --path radicle-node --force --locked
cargo install --path radicle-remote-helper --force --locked

Or directly from our seed node:

cargo install --force --locked --git https://seed.radicle.xyz/z3gqcJUoA1n9HaHKufZs5FCSGazv5.git \
    radicle-cli radicle-node radicle-remote-helper
