# 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.
