Fix hang on broken stderr. If stderr is closed and cargo tries to print a status message such as "Compiling", cargo can get into a hung state. This is because the `DrainState::run` function would insert the job into the `active` queue, and then return an error without starting the job. Since the job isn't started, there is nothing to remove it from the `active` queue, and thus cargo hangs forever waiting for it to finish. The solution is to move the call to `note_working_on` earlier before the job is placed into the active queue. This addresses the issue noted in https://github.com/rust-lang/cargo/issues/8714#issuecomment-783787163.
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.
