def GetTestSubsystemForChange(build_root, change):
"""Get a list of subsystem that a given |change| affects.
If subsystem is specified in the commit message, use that. Otherwise, look in
appropriate COMMIT-QUEUE.ini. If subsystem is not specified anywhere,
'subsystem:default' will be used.
Based on the subsystems a given |change| affects, the CQ could tell whether a
failure is potentially caused by this |change|. The CQ could then submit some
changes in the face of unrelated failures.
Args:
build_root: The root of the checkout.
change: Change to examine, as a PatchQuery object.
Returns:
A list of subsystem for the given |change|.
