# Test, Go. Push and pull request to development. Never on main.

|
|
# The gates are the ones the justfile's `gates` recipe runs, minus race: the shared
|
|
# runner box cannot afford the race detector on every push, so it lives in race.yml.
|
|
# The box is one core and 2 GB beside Gitea, so parallelism is bounded on purpose and
|
|
# everything runs in one job. Extra jobs would duplicate the checkout, the Go setup and
|
|
# the dependency download three times without buying any parallelism.
|
|
#
|
|
# Every step is one command, so the step that fails is the gate that failed, and no shell
|
|
# option has to be trusted for the run to stop. The scripted steps are Perl, not shell and
|
|
# not Python: Perl behaves the same on both runner images, there is no bashism to trip over
|
|
# on ash, and it is one language instead of two. The Perl uses builtins only, because
|
|
# Fedora packages the Perl modules separately and nothing beyond `perl` itself may be
|
|
# assumed present.
