feat(publish): Support 'publish.timeout' config behind '-Zpublish-timeout' Originally, crates.io would block on publish requests until the publish was complete, giving `cargo publish` this behavior by extension. When crates.io switched to asynchronous publishing, this intermittently broke people's workflows when publishing multiple crates. I say interittent because it usually works until it doesn't and it is unclear why to the end user because it will be published by the time they check. In the end, callers tend to either put in timeouts (and pray), poll the server's API, or use `crates-index` crate to poll the index. This isn't sufficient because - For any new interested party, this is a pit of failure they'll fall into - crates-index has re-implemented index support incorrectly in the past, currently doesn't handle auth, doesn't support `git-cli`, etc. - None of these previous options work if we were to implement workspace-publish support (https://github.com/rust-lang/cargo/issues/1169) - The new sparse registry might increase the publish times, making the delay easier to hit manually - The new sparse registry goes through CDNs so checking the server's API might not be sufficient - Once the sparse registry is available, crates-index users will find out when the package is ready in git but it might not be ready through the sparse registry because of CDNs This introduces unstable support for blocking by setting `publish.timeout` to non-zero value. A step towards #9507
Cargo
Cargo downloads your Rust project’s dependencies and compiles your project.
To start using Cargo, learn more at The Cargo Book.
To start developing Cargo itself, read the Cargo Contributor Guide.
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
Requirements
Cargo requires the following tools and packages to build:
cargoandrustc- A C compiler for your platform
git(to clone this repository)
Other requirements:
The following are optional based on your platform and needs.
-
pkg-config— This is used to help locate system packages, such aslibsslheaders/libraries. This may not be required in all cases, such as using vendored OpenSSL, or on Windows. -
OpenSSL — Only needed on Unix-like systems and only if the
vendored-opensslCargo feature is not used.This requires the development headers, which can be obtained from the
libssl-devpackage on Ubuntu oropenssl-develwith apk or yum or theopensslpackage from Homebrew on macOS.If using the
vendored-opensslCargo feature, then a static copy of OpenSSL will be built from source instead of using the system OpenSSL. This may require additional tools such asperlandmake.On macOS, common installation directories from Homebrew, MacPorts, or pkgsrc will be checked. Otherwise it will fall back to
pkg-config.On Windows, the system-provided Schannel will be used instead.
LibreSSL is also supported.
Optional system libraries:
The build will automatically use vendored versions of the following libraries. However, if they are provided by the system and can be found with pkg-config, then the system libraries will be used instead:
libcurl— Used for network transfers.libgit2— Used for fetching git dependencies.libssh2— Used for SSH access to git repositories.libz(aka zlib) — Used for data compression.
It is recommended to use the vendored versions as they are the versions that are tested to work with Cargo.
Compiling
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.
