This new action is intended to help us maintainers determine when feature
branches cause breaking formatting changes by running rustfmt (master)
and the feature branch on various rust repositories.
Over time I expect the list of checked projects to increase.
With this action in place we can more easily test that a new feature or
bug fix doesn't introduce breaking changes. Although this action needs to
be manually triggered right now, we might consider adding it to our CI
runs in the future.
There are some tests in the rustfmt test suite that are ignored by
default. I believe these tests are ignored because they have caused
issues with the the `rust-lang/rust` test suite.
However, we recently experienced an issue (5395) that would have been
avoided had these tests been running.
With the introduction of the new `#[rustfmt_only_ci_test]` attribute
macro we can run these tests when the `RUSTFMT_CI` environment variable
is set, which will presumably only be set during rustfmts CI runs.
When the environment variable is not set the `#[rustfmt_only_ci_test]`
will be replaced with an `#[ignore]`.
* config_proc_macro: fix failing doctests
* ci: include config_proc_macro crate in ci
* [review] working native windows ci
* [fix] add --locked file for ci
* [fix] quoting of cmd variables
There was recently an issue where `cargo install` was installing a newer
version of a dependency than the one listed in our Cargo.toml. The newer
version added deprecation warnings that caused our continuous integration
tests to break.
As mentioned in the `cargo help install` docs, passing the `--locked`
flag should force cargo to use the `Cargo.lock` file included with
the repository.
The `cargo test --all` command failed and exited the main process with a
SIGINT. Trapping the signal or trying to get the code of a subshell
didn't work.

This commit adds integration tests against some crates in the
nursery.
Each integration test is added as a separate build-bot, where
the rust-lang-nursery/${CRATE} is first downloaded and its tests run.
Afterwards, `cargo fmt --all` is applied to the crate, and the tests
are re-run. If the tests fail after formatting, the integration test
fails.
The crates that currently fail are added as allowed-to-fail, but the
intent is that either these crates or rustfmt should be fixed such
that the tests pass.
