I found a bug in the manifest parser and figured this would help make it
more obvious.
Since I was already changing the order, I figure I'm make things a
little more logical (user-facing first, implementtion details later)
Originally it was only included for packages that have executables or
examples for `cargo install`, however this causes inconsistencies and
is kind of unexpected nowadays, e.g. with cdylib crates.
Including it always only slightly increases the crate size and allows
for all crates to know a set of dependency versions that were working,
which can make regression tracking easier.
Fixes https://github.com/rust-lang/cargo/issues/13447
PR #5335 added `autobins`, etc for #5330. Nowhere in there is
discussion of `autolib`.
Cargo script disables support for additional build-targets by disabling
discovery.
Except we don't have a way to disable discovery of `autolib`, leading to #14476.
By adding `autolib`, we can continue in that direction.
This also allows us to bypass inferring of libs on published packages,
like all other build-targets which were handled in #13849.
As this seems fairly low controversy, this insta-stabilizes the field.
In prior versions of Cargo, users will get an "unused manifest key"
warning.
For packags where this is set by `cargo publish`, the warning will be suppressed and things will work as normal.
For `cargo vendor`, the same except there will be some churn in the
vendored source as this field will now be set.
For local development, it should be rare to set `autolib` so the lack of
error by discovering a file when this is set shouldn't be a problem.
Fixes#14476
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.
Once we support packaging workspaces with dependencies, dependency
packages need to be built before anything is verified. In addition to a
little refactoring, this commit reorders the console messages so that
package metadata (archive size, etc.) is reported before verification
results.

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 could offer performance gains when parsing a published
manifest since the targets don't need to be discovered.
To see this, we'd first need to stop discovering potential targets even when it isn't
needed.
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.
crates.io reads rust-version from the tarball directly, but we can include it in
the publish request for the sake of consistency for third-party registries.
Originally, crates.io would block on publish requests until the publish
was complete, giving `cargo publish` this behavior by extension. When
crates.io switched to asynchronous publishing, this intermittently broke
people's workflows when publishing multiple crates. I say interittent
because it usually works until it doesn't and it is unclear why to the
end user because it will be published by the time they check. In the
end, callers tend to either put in timeouts (and pray), poll the
server's API, or use `crates-index` crate to poll the index.
This isn't sufficient because
- For any new interested party, this is a pit of failure they'll fall
into
- crates-index has re-implemented index support incorrectly in the past,
currently doesn't handle auth, doesn't support `git-cli`, etc.
- None of these previous options work if we were to implement
workspace-publish support (#1169)
- The new sparse registry might increase the publish times, making the
delay easier to hit manually
- The new sparse registry goes through CDNs so checking the server's API
might not be sufficient
- Once the sparse registry is available, crates-index users will find
out when the package is ready in git but it might not be ready through
the sparse registry because of CDNs
So now `cargo` will block until it sees the package in the index.
- This is checking via the index instead of server APIs in case there
are propagation delays. This has the side effect of being noisy
because of all of the "Updating index" messages.
- This is done unconditionally because cargo used to block and that
didn't seem to be a problem, blocking by default is the less error
prone case, and there doesn't seem to be enough justification for a
"don't block" flag.
The timeout was 5min but I dropped it to 1m. Unfortunately, I don't
have data from `cargo-release` to know what a reasonable timeout is, so
going ahead and dropping to 60s and assuming anything more is an outage.
Fixes#9507
Benefits:
- A TOML 1.0 compliant parser
- Unblock future work
- Have `cargo init` add the current crate to the workspace, rather
than error
- #5586: Upstream `cargo-add`
Unify weak and namespaced features.
This unifies weak and namespaced features in order to simplify the syntax and semantics. Previously there were four different ways to specify the feature of a dependency:
* `package-name/feature-name` — Enables feature `package-name` on self and enables `feature-name` on the dependency. (Today's behavior.)
* `package-name?/feature-name` — Only enables `feature-name` on the given package if it that package is enabled and will also activates a feature named `package-name` (which must be defined implicitly or explicitly).
* `dep:package-name/feature-name` — Enables dependency `package-name`, and enables `feature-name` on that dependency. This does NOT enable a feature named "package-name".
* `dep:package-name?/feature-name` — Only enables `feature-name` on the given package if it that package is enabled. This does NOT enable a feature named "package-name".
This changes it so there are only two:
* `package-name/feature-name` — Today's behavior.
* `package-name?/feature-name` — Only enables `feature-name` on the given package if it that package is enabled. This does NOT enable a feature named "package-name" (the same behavior as `dep:package-name?/feature-name` above).
This is a fairly subtle change, and in most cases probably won't be noticed. However, it simplifies things which helps with writing documentation and explaining how it works.
Previously, when something was stabilized, Cargo would spit out a very
unhelpful error message about an unknown -Z flag. This changes it so
that it displays a helpful warning (or error).
