Old macOS images are deprecated resulting in often failures, thus use
latest macOS images available.
Also given that macOS is arm64 by default check x86_64 as extra job
and not arm64.
Instead of manually specifying the oldstable version in all our CI
scripts, it is now pulled from the `Cargo.toml` which simplifies the
update process.
The contributing guide has also been updated to not include the explicit
version and its wording has been loosened a bit to correctly represent
current maintenance practices.
The glutin 0.30.0 update decouples glutin from winit which
provides us with basis for a multithreaded renderer. This
also improves robustness of our configuration picking,
context creation, and surface handling.
As an example we're now able to start on systems without a vsync,
we don't try to build lots of contexts to check if some config works,
and so on.
That also brings us possibility to handle context losses, but that's
a future work.
Fixes#1268.
Since the CI machine is amd64, it is not possible to just execute the
aarch64 binary to test the application. So instead of running `cargo
test`, we just use `cargo build` instead.
Building on the non-release CI instead of just checking also allows us
to make sure linking works properly before a release fails due to it.
Since not all suggested clippy lints by stable clippy are supported on
the MSRV of Alacritty, this commit moves the clippy checks to the MSRV.
Unfortunately this will mean that our lints might be significantly
behind, however it ensures our CI never blocks any code that should be
valid.
Developers themselves of course can still run the latest clippy to
follow the up to date recommendations.
By reducing the number of CI jobs for GitHub actions, it should be
possible to get a faster overview over the status of all CI jobs. While
this does increase the total build time of GitHub Actions by reducing
parallelization, it should still finish within the SourceHut CI times.
This removes all CI builds from travis-ci, due to their recent changes
in policy and harsh limitations on builds. With build times over 2
hours, it was a significant hindrance to development.
Instead of Travis CI, the CI is now split on Sourcehut and GitHub. Since
Sourcehut only supports Linux/BSD, all builds on those operating systems
are executed there. The GitHub Actions CI is used to build for
Windows/macOS, which are not available on Sourcehut.
Since asset deployment for releases requires builds on all platforms,
this is also done on GitHub actions. Though the new `upload_asset.sh`
script makes sure that migration in the future is fairly simple and we
do not tie ourselves to the overly complicated GitHub Actions ecosystem.
