This is for `cargo generate-lockfile` and when syncing the lockfile with
the manifest.
We still show it for `cargo update` because of `cargo update
--workspace`.
We hacked around this previously by filtering out the `num_pkgs==1` case
for single packages but this didn't help with workspaces.
We now include the prelude in so many places, this simplifies how we can
present how `cargo-test-support` works.
Yes, this included some `use` clean ups but its already painful enough
walking through every test file, I didn't want to do it twice.
While this is noisy and hides other deprecations, I figured deprecations would
make it easier for people to discover what tasks remain and allow us to
divide and conquer this work rather than doing a heroic PR.
In theory, this will be short lived and we'll go back to seeing
deprecations in our tests.
This is to help with #9930
Example changes:
```diff
-[LOCKING] 4 packages
+[LOCKING] 4 packages to latest version
-[LOCKING] 2 packages
+[LOCKING] 2 packages to latest Rust 1.60.0 compatible versions
-[LOCKING] 2 packages
+[LOCKING] 2 packages to earliest versions
```
Benefits
- The package count is of "added" packages and this makes that more
logically clear
- This gives users transparency into what is happening, especially with
- what rust-version is use
- the transition to this feature in the new edition
- whether the planned config was applied or not (as I don't want it to
require an MSRV bump)
- Will make it easier in tests to show what changed
- Provides more motiviation to show this message in `cargo update` and
`cargo install` (that will be explored in a follow up PR)
This does come at the cost of more verbose output but hopefully not too
verbose. This is why I left off other factors, like avoid-dev-deps.
By doing so, rustdoc will also emit workspace-relative filenames for the doctests.
This was first landed in #8954 but later backed out in #8996 because it changed the CWD of rustdoc test invocations.
The second try relies on the new `--test-run-directory` rustdoc option which was added in https://github.com/rust-lang/rust/pull/81264 to explicitly control the rustdoc test cwd.

This commit stabilizes Cargo's `rename-dependency` feature which allows
renaming packages in `Cargo.toml`, enabling importing multiple versions
of a single crate or simply avoiding a `use foo as bar` in `src/lib.rs`.
Closes#5653
This change ensures cargo will output file paths in the expected format
(C:\foo\... on Windows, /foo/... elsewhere). Previously it would output
file:// URLs instead.
To support this change, additional changes were made to the test suite
string processing such that [ROOT] is now replaced with the appropriate
file path root for the platform.
The CWD template was also updated to use [CWD] like other replacement
templates and to do the replacement on the expected value rather than
the actual value to avoid replacing things we don't expect with CWD.
.. with mutliple calls of:
fastmod --accept-all '\.cargo\("([^"]+)"\)\.arg\("([^"]+)"\)' '.cargo("${1} ${2}")' tests/testsuite/
until no changes are left.
This commit updates the implementation of renamed dependencies to use the listed
name of a dependency in Cargo.toml for the name of the associated feature,
rather than using the package name. This'll allow disambiguating between
different packages of the same name and was the intention all along!
Closes#5753
* Collapse the nested cargotest::support module into the cargotest
module (merge the mod.rs's)
* Rename the cargotest module to support
* Nest the top-level hamcrest module into support
By rewriting the tests, with rerast (https://github.com/google/rerast),
to use the newly introduced "at" method.
First I added the following temporary function to cargotest::support:
pub fn project_foo() -> ProjectBuilder {
project("foo")
}
Then I defined the following rewrite.rs:
use cargotest::support::{ project, project_foo };
fn rule1(a: &'static str) {
replace!(project("foo") => project_foo());
replace!(project(a) => project_foo().at(a));
}
Then I ran rerast:
cargo +nightly rerast --rules_file=rewrite.rs --force --targets tests --file tests/testsuite/main.rs
Finally I searched and replaced the references to project_foo with
argument-less project (a little awkardly on macOS with a git clean).
find tests -type f -exec sed -i -e 's/project_foo/project/g' {} +
git clean -d tests
Previously there was a verification in manifest parsing that the same dependency
must come from the same source, but this erroneously triggered an error to get
emitted when the `package` key was used to rename crates. The first change here
was to update that clause to key off the `rename` field rather than the `name`
field.
Afterwards, though, this exposed an existing bug in the implementation. During
compilation we have a `Resolve` which is a graph of crates, but we don't know
*why* each edge in the dependency graph exists. In other words we don't know,
when looking at an edge of the graph, what `Dependency` caused that edge to be
drawn. We need to know this when passing `--extern` flags because the
`Dependency` is what lists what's being renamed.
This commit then primarily refactors `Resolve::deps` from an iterator of package
ids to an iterator of a tuples. The first element is the package id from before
and the second element is a list of `Dependency` directives which caused the
edge to ber driven.
This refactoring cleaned up a few places in the backend where we had to work
around the lack of this knowledge. Namely this also fixes the extra test added
here.
Closes#5413
This hasn't been updated in awhile and in general we've been barely using it.
This drops the outdated dependency and vendors a small amount of the
functionality that it provided. I think eventually we'll want to transition away
from this method of assertions but I wanted to get this piece in to avoid too
much churn in one commit.
