Currently, when reading a file from disk, we include several pieces of data from the on-disk file, including the user and group names and IDs, the device major and minor, the mode, and the timestamp. This means that our archives differ between systems, sometimes in unhelpful ways. In addition, most users probably did not intend to share information about their user and group settings, operating system and disk type, and umask. While these aren't huge privacy leaks, cargo doesn't use them when extracting archives, so there's no value to including them. Since using consistent data means that our archives are reproducible and don't leak user data, both of which are desirable features, let's canonicalize the header to strip out identifying information. Omit the inclusion of the timestamp for generated files and tell the tar crate to copy deterministic data. That will omit all of the data we don't care about and also canonicalize the mode properly. Our tests don't check the specifics of certain fields because they differ between the generated files and the files that are archived from the disk format. They are still canonicalized correctly for each type, however.
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:
git
curl
(on Unix)pkg-config
(on Unix, used to figure out thelibssl
headers/libraries)- OpenSSL headers (only for Unix, this is the
libssl-dev
package on ubuntu) cargo
andrustc
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.
