#
# There are two different types of pipelines:

#  - marge-bot merges to `master`. Here we perform an exhaustive validation
#    across all of the platforms which we support. In addition, we push
#    performance metric notes upstream, providing a persistent record of the
#    performance characteristics of the compiler.
#
#  - merge requests. Here we perform a slightly less exhaustive battery of
#    testing. Namely we omit some configurations (e.g. the unregisterised job).
#    These use the merge request's base commit for performance metric
#    comparisons.
#

####
# HACK
###
#
# Since 58cfcc65 the default for jobs has been "interruptible", this means
# that when new commits are pushed to a branch which already has a running
# pipeline then the old pipelines for this branch are cancelled.
#
# This includes the master branch, and in particular, new commits merged
# to the master branch will cancel the nightly job.
#
# The semantics of pipeline cancelling are actually a bit more complicated
# though. The interruptible flag is *per job*, but once a pipeline has run
# *any* non-interruptible job, then the whole pipeline is considered
# non-interruptible (ref
# https://gitlab.com/gitlab-org/gitlab/-/issues/32837). This leads to the
# hack in this MR where by default all jobs are `interruptible: True`, but
# for pipelines we definitely want to run, there is a dummy job which
# happens first, which is `interreuptible: False`. This has the effect of
# dirtying the whole pipeline and
#
# For now, this patch solves the immediate problem of making sure nightly
# jobs are not cancelled.
# In the future, we may want to enable this job also for the master
# branch, making that change might mean we need more CI capacity than
# currently available.
