    ## We want the CI to run on both branches and tags, so we should either have:
    ## - both (tags or tags-ignore) and (branches or branches-ignore),
    ## - or neither of them.
    ## But it's important to not have only one or the other.

# In this file, we set `--cpu-shares 4096` on every job. This might seem useless
# since it means that every container has the same weight which should be
# equivalent to doing nothing, but it turns out that OpenJDK computes
# `Runtime.getRuntime.availableProcessors` by dividing the cpu-shares value if
# it exists by 1024 (cf
# http://mail.openjdk.java.net/pipermail/hotspot-dev/2019-January/036087.html),
# so this means that we effectively run every job with 4 cores. This is much
# nicer than setting `--cpus 4` because the latter enforces CPU quotas and ends
# up slowing our jobs more than needed. It's equivalent to running the JVM with
# `-XX:ActiveProcessorCount=4`, but since our tests can spawn new JVM in many
# places, it would be very hard to ensure that this option is always passed to
# `java` (we could use the `_JAVA_OPTIONS` environment variable, but this prints
# text on stderr and so can break tests which check the output of a program).
