# We'll test iprop, and in particular, hierarchical iprop. This means we'll
# have a setup like:
#
# ipropd-master -> ipropd-slave -> 2nd ipropd-master -> 2nd ipropd-slave
# Waiting for incremental propagation is inherently difficult because we don't
# have a way for ipropd-slave to signal this script that it has received
# updates. Well, it does have a way to signal a possible ipropd-master for
# hierarchical iprop, but we don't have a way to get that signal here.
#
# FIXME: Add a private interface for async waiting for iprop.
#
# What we do is we have a set of utility functions:
#
# - get_iprop_ver [N] -> checks that N (default to 1) ops have made it over
# - get_iprop_ver2 [N] -> same, but for second ipropd-slave instance
#
# - wait_for -> repeat a command until it succeeds or too many tries
# - wait_for_slave [N] -> wait for N ops to make it over (calls get_iprop_ver)
# - wait_for_slave2 [N] -> same, but for second ipropd-slave instance
#
# In particular the wait_for* functions busy-wait for a max amount of time,
# with sleeps in between.
#
# NOTE: get_iprop_ver and get_iprop_ver2 keep hidden state.
#
# When first called, get_iprop_ver / get_iprop_ver2 save the current version
# numbers. Thereafter they check that N ops have been received.
#
# It is critical to account for every incremental op via get_iprop_ver /
# get_iprop_ver2, or wait_for_slave / wait_for_slave2, otherwise this test will
# be racy and will have spurious failures!
#
# The pattern should be something like this:
#
# echo "Add host"
# ${kadmin} -l add --random-key --use-defaults host/foo@${R} || exit 1
# wait_for_slave
# ^^^^^^^^^^^^^^
# waits for 1 operation
#
# or
#
# echo "Rollover host keys"
# ${kadmin} -l cpw -r --keepold host/foo@${R} || exit 1
# ${kadmin} -l cpw -r --keepold host/foo@${R} || exit 1
# ${kadmin} -l cpw -r --keepold host/foo@${R} || exit 1
# wait_for_slave 3
# ^^^^^^^^^^^^^^^^
# waits for the three operations
#
# So though all operations must be accounted for, they need not be accounted
# one by one.
