cargo-llvm-cov

Use cargo-config2 to load Cargo configuration. (https://github.com/taiki-e/cargo-llvm-cov/pull/237)

This brings the following improvements:

• More accurate cargo configuration loading and resolution.
• Fix installation failure on Rust 1.60 and 1.61 by removing dependency on target-spec.
• Remove run-time dependency on unstable cargo config get. (Previously, this command was used in a form allowing failure, like rust-analyzer does.)

Fix an issue where coverage of binary targets containing hyphens was not collected correctly. (#232)

Fix help messages for cargo llvm-cov report subcommand.

Add --cobertura flag to support Cobertura's XML report format. (#224, thanks @mike-kfed)

Limit the number of test threads for nextest to work around rust-lang/rust#91092. (#223)

For subcommands other than cargo llvm-cov nextest, the same workaround has already been applied since 0.4.6.

Replace atty with is-terminal. (#226)

Improve handling of cases where llvm-tools-preview component is not installed. (#219)

TL;DR: You no longer need to manually install llvm-tools-preview before running cargo-llvm-cov in most cases.

The new logic is based on the logic used by Miri when rust-src component or xargo is not installed.

See #219 for more.

Fix various CLI-related bugs. (#197, #217)

This fixes various bugs related to subcommands (especially nextest). The following is a partial list:

• Fix errors for nextest-specific options. (#151, #144, #213, etc.)
• Fix problems where some options were ignored in cargo llvm-cov run and cargo llvm-cov nextest subcommands. (#151, #144, #198, etc.)
• Fix help messages for subcommands.

Add cargo llvm-cov report subcommand. (#217) This is equivalent to cargo llvm-cov --no-run, but it has a more obvious name and better diagnostics.

Add cargo llvm-cov test subcommand. (#217) This is equivalent to cargo llvm-cov without subcommand, except that test name filtering is supported.

Deprecate --no-run in favor of cargo llvm-cov report subcommand. (#217)

Add --no-clean flag to build without cleaning any old build artifacts. See #214 for more.

cargo-llvm-cov no longer redirects output from stdout to stderr if unnecessary. (#206)

Support shared target directory. (#215)

Support --keep-going (unstable), --ignore-rust-version. (#217)

Support --exclude-from-report and --ignore-run-fail for cargo llvm-cov run. (#217)

Support relative path in CARGO_LLVM_COV_TARGET_DIR. (#220)

Add LLVM_COV_FLAGS/LLVM_PROFDATA_FLAGS environment variables to pass additional flags to llvm-cov/llvm-profdata in a space-separated list. (#220)

Deprecate CARGO_LLVM_COV_FLAGS/CARGO_LLVM_PROFDATA_FLAGS environment variables instead of LLVM_COV_FLAGS/LLVM_PROFDATA_FLAGS environment variables. (#220)

Document environment variables that cargo-llvm-cov reads. (#220)

Remove cargo llvm-cov help subcommand that was added automatically by clap. (#197)

cargo-llvm-cov no longer maps the --jobs (-j) option to llvm-cov/llvm-profdata's -num-threads option.

This is to avoid confusion when using the -j option with nextest, which uses the -j option in a different sense than cargo.

Improve compile time. (#197)

Diagnostics improvements.

Support target.<cfg>.rustflags. (#200)

Remove workaround for an old rustc bug on Windows if unnecessary. (#199, thanks @ldm0)
