Fix fix::fix_in_dependency to not rely on rustc

This changes the `fix::fix_in_dependency` test so that it does not rely on the behavior of rustc.

This test is checking the behavior when rustc includes a suggestion diagnostic that modifies a file in CARGO_HOME from a dependency. rustc should not be emitting suggestions that point outside of the current crate, but there are some known bugs where it does this. #9938 added a workaround for this to avoid writing to CARGO_HOME.

However, the current test was relying on one of those bugs in rustc to exhibit its behavior. https://github.com/rust-lang/rust/pull/119204 is fixing that particular behavior. Instead of relying on issues in rustc, this PR changes the test so that the test creates a fake `rustc` executable that will emit a hard-coded JSON message that tells `cargo fix` to modify a file in CARGO_HOME. This should be stable as it is no longer relying on rustc.

Testing or validating this change is a little tricky. You have to essentially comment out [these three lines](4f70d1781a/src/cargo/ops/fix.rs (L654-L656)) from the original #9938 change, and verify that the test fails (it says "Fixed" in the output). With those three lines in place, it should pass.

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

CI

Code documentation: https://doc.rust-lang.org/nightly/nightly-rustc/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:

Other requirements:

The following are optional based on your platform and needs.

  • pkg-config — This is used to help locate system packages, such as libssl headers/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-openssl Cargo feature is not used.

    This requires the development headers, which can be obtained from the libssl-dev package on Ubuntu or openssl-devel with apk or yum or the openssl package from Homebrew on macOS.

    If using the vendored-openssl Cargo feature, then a static copy of OpenSSL will be built from source instead of using the system OpenSSL. This may require additional tools such as perl and make.

    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.git
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.

Reporting issues

Found a bug? We'd love to know about it!

Please report all issues on the GitHub issue tracker.
