# This is our main "CI tests" workflow. It runs everything that should run on
# both PRs and merged commits, and for the latter reports failures to slack.
name: CI
env:
# Our fuzz job, powered by OSS-Fuzz, fails periodically because we upgrade to
# new Go versions very eagerly. OSS-Fuzz is a little more conservative, and
# ends up being unable to compile our code.
#
# When this happens, we want to disable the fuzz target until OSS-Fuzz catches
# up. However, we also don't want to forget to turn it back on when OSS-Fuzz
# can once again build our code.
#
# This variable toggles the fuzz job between two modes:
# - false: we expect fuzzing to be happy, and should report failure if it's not.
# - true: we expect fuzzing is broken, and should report failure if it start working.

# This target periodically breaks (see TS_FUZZ_CURRENTLY_BROKEN at the top

# might or might not be fine. The steps after the build figure out whether
# the success/failure is expected, and appropriately pass/fail the job
# overall accordingly.
#
# Practically, this means that all steps after 'build fuzzers' must have an
# explicit 'if' condition, because the default condition for steps is
# 'success()', meaning "only run this if no previous steps failed".
