These flags were previously only needed due to a bug in the `cargo-semver-checks` CLI logic.
The correct behavior (available as of v0.18.3) for `cargo-semver-checks` is to ignore `publish = false` crates when scanning a workspace, *unless* those crates are specifically selected for checking.
All the crates being excluded here are `publish = false` so they are already excluded by the default behavior, so all `--exclude` flags are no-ops.
Fixes#5373Closes#5358
- Add check for no_atomic_u64 & no_const_mutex_new (condition to atomic_u64_static_once_cell.rs is compiled)
- Allow unused_imports in TARGET_ATOMIC_U64_PROBE. I also tested other *_PROBE and found no other errors triggered by -D warning.
- Fix cfg of util::once_cell module
- Use dtolnay/rust-toolchain instead of actions-rs/toolchain
- Use cargo/cross directly instead of actions-rs/cargo
- Use rustsec/audit-check instead of actions-rs/audit-check
This adds CI coverage for a couple of code paths that are not currently
hit in CI:
* no `const fn Mutex::new`
* no `AtomicU64`
This is done by adding some new CFG flags used only for tests in order
to force those code paths.
Previously, calling `task::yield_now().await` would yield the current
task to the scheduler, but the scheduler would poll it again before
polling the resource drivers. This behavior can result in starving the
resource drivers.
This patch creates a queue tracking yielded tasks. The scheduler
notifies those tasks **after** polling the resource drivers.

This patch updates CI to use `cross` to run Tokio tests on virtualized
ARM and i686 VMs. Because ipv6 doesn't work on Github action running in
a docker instance, those tests are disabled
As has been pointed out a few times in the past (e.g., #4036 (comment)), each-feature
is not sufficient for features check.
Ideally, we'd like to check all combinations of features, but there are too many
combinations. So limit the max number of simultaneous feature flags to 2 by --depth
option. I think this should be sufficient in most cases as @carllerche said in
taiki-e/cargo-hack#58.
Years ago, Tokio was organized as a cluster of separate crates. This
architecture required a trait to represent "park the thread and do
work.". When all crates were combined into a single crate, the `Park`
and `Unpark` traits remained as internal details.
This patch removes these traits as they are no longer needed. This is in
service of a future refactor that will decouple the various resource
drivers and store them in a single struct instead of nesting them.
However, in the mean time, removing the Park/Unpark traits adds a bit of
messy code to make the conditional compilation work. This code will
(hopefully) be short-lived.
Upgrade the nightly to a version that works with all of miri,
cargo-hack, minimal-versions, and cargo-check-external-types.
This is a prerequisite for #4902.
This adds initial, unstable, support for the wasm32-wasi target. Not all of Tokio's
features are supported yet as WASI's non-blocking APIs are still limited.
Refs: tokio-rs/tokio#4827
Currently, we only have WASM regression tests that run without WASI.
However, rust provides a WASI specific target which enables code to
special case WASI. This PR adds a basic test to cover that case.
This is an initial addition to help land tokio-rs/tokio#4716.
It turns out that the CI job for testing `tokio_unstable` features isn't
actually running doctests for `tokio_unstable`, just lib and integration
tests. This is because RustDoc is responsible for running doctests, and
it needs the unstable cfg passed to it separately from `RUSTFLAGS`.
This means that if the examples for unstable APIs are broken, CI won't
catch this, which is not great!
This commit changes the `test-unstable` CI job to pass `--cfg
tokio_unstable` in `RUSTDOCFLAGS` as well as `RUSTFLAGS`. This way,
doctests for unstable APIs should actually run.
I also fixed a typo in one of the runtime metrics doctests that was
causing a compilation error, which was caught as a result of actually
testing the unstable API docs on CI. :)

When backporting patches to LTS branches, we often run into CI failures due to
changes in rust. Newer rust versions add more lints, which break CI. We really
don't want to also have to backport patches that fix CI, so instead, LTS branches
should pin the stable rust version in CI (e.g. #4434).
This PR restructures the CI config files to make it a bit easier to set a specific rust
version in CI.
* Several of tokio's features (e.g. the channel implementation) do not
need a runtime to work, and can be compiled and used for
wasm32-unknown-unknown targets
* This change enables running tests for the `sync` and `macros` features
so that we can note any regressions there
