This leverages the unstable `--emit=depinfo` option from rustdoc,
so that rustdoc invocation rebuild can be better tracked
without traversing the entire directory.
Some design decisions:
* Rustdoc's depinfo doesn't and shouldn't emit to `target/doc`,
as the directory is considered part of the final artifact directory.
In regard to that, we specify the dep-info output path to
the fingerprint directory of rustdoc invocation.
It looks like this
`target/debug/.fingerprint/serde-12d29d32b3b8b38f/doc-lib-serde.d`.
* We also start supporting `-Zchecksum-freshness` as a side effect.
Could make it a separate PR if desired.
* `-Zbinary-dep-depinfo` is not enabled along with this,
since doc generations don't really require any binary dependencies.
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.
cargo: prevent dashes in lib.name
The TOML parser of Cargo currently refuses `lib.name` entries that contain dashes. Unfortunately, it uses the package-name as default if no explicit `lib.name` entry is specified. This package-name, however, can contain dashes.
Cargo documentation states that the package name is converted first, yet this was never implemented by the code-base.
Fix this inconsistency and convert the package name to a suitable crate-name first.
This fixes#12780. It is an alternative to #12640.
This commit lifts a helper function from invoking rustc to additionally
being used for invoking rustdoc. This enables hiding the command line
invocation of `rustdoc` by default when it fails, although it's still
available to see with `--verbose`. The intention here is to match the
behavior of `cargo build` for rustc failures here and was inspired by
recently running `cargo doc` and not being able to see the actual
failure as the command line ended up taking the whole screen (afterwards
I made the screen bigger and that helped too).
In 12914 we stabilized pkgid spec as unique package identifier for
`cargo metadata`. However, we forgot to make the same change to
JSON message format[^1]. This PR does so.
Note that the `package_id` field in JSON message is not clearly stated
as "opaque", so it might be considered as a breaking change to some extent.

I've wanted something like this myself. I dislike using `--open`
because I tend to move up to re-run my `cargo doc` run but then have to
edit it to remove `--open`.
Also makes it annoying when opening docs when `cargo doc` is wrapped by
a tool like `make`.
This was previously attempted in #5592:
- Unlike the request in #5562, this aligns with #5592 in always printing
rather than using a flag as this seems generally useful
- Unlike #5592, this prints as an alternative to "Opening" to keep
things light
- Unlike #5592, this prints afterwards as the link is only valid then
Fixes#5562

This stabilizes and enables the `-Z doctest-in-workspace` flag by default.
Also adds another testcase to make sure that the `include!()` and `file!()` macros interact well together.
When documenting private items in a binary, ignore warnings about links to private items
Previously, rustdoc would warn about linking to private items in a binary, even
though cargo unconditionally documents private items in a binary.
This changes cargo to silence the warning, since it's only relevant in
cases where the private items might not be documented.
Fixes https://github.com/rust-lang/rust/issues/89600.
