# BUG#22336669 - TIMEOUT WHILE SHUTTING DOWN THE SERVER WITH PREPARED PROCEDURES
|
|
# RUNNING
|
|
#
|
|
# Test to check if the server hangs while a STOP GROUP_REPLICATION command is
|
|
# executed and a stored procedure is running.
|
|
#
|
|
# Test:
|
|
# 0. The test requires two servers: M1 and M2.
|
|
# 1. With both the members ONLINE. On M1 create a table and stored procedure(SP)
|
|
# to insert 199 rows in the table created.
|
|
# 2. Set DEBUG point to hang SP at the before commit hook. Call SP and
|
|
# simultaneously stop GR on M1.
|
|
# 3. Signal to continue_commit. Check that BUG#22336669 fixes the hang. Wait
|
|
# for the 199 rows in the table.
|
|
# 4. Assert check that SP was executed only on M1's binary log and was logged
|
|
# with M1's UUID. It never reached the binary log of M2. On M2 there is
|
|
# only 5 transactions logged with group UUID.
|
|
# 5. Clean up.
