Fix fetching git repos after a force push. Users have been reporting that the index has not been updating for them. This was caused by the update to libgit2 1.3 (from 1.1) which has changed some behavior around force pushes. The index was squashed on 2021-09-24, and if a user had the index fetched from before that point, and they used nightly-2021-10-14 or newer, then the fetch would succeed, but the `refs/remotes/origin/HEAD` would not get updated. Cargo uses the `origin/HEAD` ref to know what to look at, and thus was looking at old data. The solution here is to use `+` on the refspec to force libgit2 to do a forced update (a fast-forward). I think this may have been introduced in libgit2 1.2 via https://github.com/libgit2/libgit2/pull/5854, though that is just a guess. Fixes #9976
Cargo
Cargo downloads your Rust project’s dependencies and compiles your project.
Learn more at https://doc.rust-lang.org/cargo/
Code Status
Code documentation: https://docs.rs/cargo/
Installing Cargo
Cargo is distributed by default with Rust, so if you've got rustc installed
locally you probably also have cargo installed locally.
Compiling from Source
Cargo requires the following tools and packages to build:
gitcurl(on Unix)pkg-config(on Unix, used to figure out thelibsslheaders/libraries)- OpenSSL headers (only for Unix, this is the
libssl-devpackage on ubuntu) cargoandrustc
First, you'll want to check out this repository
git clone https://github.com/rust-lang/cargo
cd cargo
With cargo already installed, you can simply run:
cargo build --release
Adding new subcommands to Cargo
Cargo is designed to be extensible with new subcommands without having to modify Cargo itself. See the Wiki page for more details and a list of known community-developed subcommands.
Releases
Cargo releases coincide with Rust releases. High level release notes are available as part of Rust's release notes. Detailed release notes are available in this repo at CHANGELOG.md.
