# This test case aims to check if the recovery routine develop as part of the
# WL#5599 works correctly. To do so, we generate a set of changes, i.e. a set
# of transactions, as follows:
#
#   DB_1 ... DB_1 DB_2 ... DB_2 ... DB_w ... DB_w
#   |         |   |         |       |         |
#   ---- a ----   ---- a ----       ---- a ----
#   |         |   |         |       |         |
#   ---- p ----   ---- p ----       ---- p ----
#   |         |
#   ---- c ----   
#
#  DB_w is a transaction on database "w" that is assigned to worker "w" and
#  may be generated "a" times. Within each "a" group, "p" transactions are
#  processed by their assigned workers and within the first group, only "c"
#  transactions are processed by the checkpoint routine.
#
#  The following properties hold:
#
#  . 0 <= p <= a
#  . 0 <= c <= p
#
#  So after assigning "a" transactions to each worker, waiting that "p"
#  transactions are processed by each worker and "c" are processed by the
#  checkpoint routine, the slave is rebooted thus executing the recovery
#  routine with a mix of processed and unprocessed transactions.
#
#  Along with this, the relay log is rotated and during startup the relay
#  log files are delete based on the option relay-log-recovery.
#
#  At the end, master and slave cannot diverge.

# Technically resetting of the repo type is implemented through
# one to slave_parallel_workers. Having it zero in the info table
# at the following restart makes the slave server to quietly migrate
# the repository to the requested type.
# Notice that Bug#15858271 of mtr does not allow effectiveness of
# zeroing.
# TODO: run the combination described on Bug#15858271 after it's fixed.
