Prior to this commit `cargo metadata` would not emit the value of a
target's "doc" setting, used by `cargo doc` to determine whether
documentation should be generated. However, this information is useful
for machine programs interested in such targets, and the information is
already made available on the internal representation of a target, so
this commit just exposes that during target serialization for emit.

This commit adds support for rustc's `-Z terminal-width` flag, which is
used to trim diagnostic output to fit within the current terminal.

Exclude the target directory from backups using CACHEDIR.TAG
This patch follows the lead of #4386 (which excludes target directories
from Time Machine backups) and is motived by the same reasons listen
in #3884. CACHEDIR.TAG is an OS-independent mechanism supported by Borg,
restic, GNU Tar and other backup/archiving solutions.
See https://bford.info/cachedir/ for more information about the
specification. This has been discussed in Rust Internals earlier this
year[1] and it seems like it's an uncontroversial improvement so I went
ahead with the patch.
One thing I'm wondering is whether this should maybe cover the whole main target directory (right now it applies to `target/debug`, `target/release` etc. but not to target root).

This is following the discussion on GitHub. The doc tests are no longer
necessary because Layout::new() creates CACHEDIR.TAG directly in target
root, no doc-specific code is necessary anymore.
Add support for `workspace.metadata` table
Implements feature request #8309
Additionally includes the information in the output of "cargo metadata" through a new top-level field `metadata`, similar to the per-package `metadata` field
Add environment variables to identify the binary and crate name
Closes#8251
This adds `CARGO_BIN_NAME` and `CARGO_CRATE_NAME` to rustc/rustdoc process env.
`CARGO_BIN_NAME` is added for binary compilation units, `CARGO_CRATE_NAME` is added for binary and library units.
The `build::crate_env_vars` test was updated to test for this. The test is currently only checking behavior for the binary compile unit.
Documentation was updated to reflect the added environment variables.
reset lockfile information between resolutions
#8249 pointed out that some kind of lockfile data was leaking between calls to the resolver. @ehuss made a reproducing test case. This PR resets the `LockedMap` data structure when calling `register_previous_locks`.
lets see if CI likes it.
fix#8249
This stops using `to_string` as a proxy for this now-provided precise API.
This reverts commit b71927224fd9306b2b5bd2b4f8c22268eadfeb6a and bupms the
dependency version in Cargo.toml.
CARGO_BIN_NAME is added for binary compilation units, CARGO_CRATE_NAME is added for binary and library units.
The `crate_env_vars` test was updated to test for this. The test is currently only checking behavior for the binary compile unit.
Fix pdb uplift when executable has dashes.
Windows `.pdb` files were not being uplifted for executables with dashes in their name. `rustc` calls the linker with the crate name (with underscores), which creates a pdb with underscores. Cargo renames the executable (`foo_bar.exe` to `foo-bar.exe`), and it was expecting the pdb to have the same form, but it doesn't.
Note: There shouldn't be any effect for using a debugger. Because the pdb path is embedded in the executable, the debugger was already looking in the `deps/` folder. Uplifting is only useful if you want to copy the exe/pdb pair to some other machine. In that case, it looks in the same directory as the `exe` for the pdb file.
Fixes#8117
Add "build-finished" JSON message.
This adds a JSON message when a build is finished. This is useful for tools to know when to stop parsing JSON, which is particularly useful for commands like `cargo test` or `cargo run` where additional output may follow.
Closes#7978
