# BUG#16741603: MYSQLD SCANS ALL BINARY LOGS ON CRASH RECOVERY
|
|
#
|
|
# Verify that the server does not scan more than one binary log
|
|
# in every iteration when initializing GTID sets on server start
|
|
# if binlog-gtid-simple-recovery is enabled. See implementation
|
|
# step 1-8.
|
|
#
|
|
# Bug #20075721 ASSERTION `LOST_GTIDS->IS_EMPTY()' AT BINLOG.CC:3637
|
|
# ON PURGE BINLOG CMD
|
|
#
|
|
# We are hitting the assertion when purging binary logs and the first
|
|
# left binary log just contains a Previous_gtids_log_event. The problem
|
|
# is caused by making GOT_PREVIOUS_GTIDS case to execute the assertion.
|
|
# This change is added after fixing Bug#16741603, but missed to
|
|
# remove the assertion.
|
|
#
|
|
# Removing the assertion to fix the problem.
|
|
#
|
|
# See implementation step 9-10.
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# 1) Start server and generate four binary logs with gtid_mode off.
|
|
# 2) Move binlog.000002 to binlog.000002.bkp and
|
|
# binlog.000003 to binlog.000003.bkp
|
|
# 3) Only binlog.000001 and binlog.000004 remain, others are moved
|
|
# , restart the server with enabled binlog-gtid-simple-recovery
|
|
# and gtid_mode on. If the server scans more than one binary log in
|
|
# every iteration, it will cause read error on the 2nd and 3rd files.
|
|
# 4) Verify that GLOBAL.GTID_EXECUTED and GLOBAL.GTID_PURGED are empty
|
|
# after server restarts.
|
|
# 5) Move binlog.000004 to binlog.000004.bkp
|
|
# 6) Only binlog.000001 and binlog.000005 remain, others are moved
|
|
# , restart the server with enabled binlog-gtid-simple-recovery
|
|
# and gtid_mode on again. If the server scans more than one binary
|
|
# log in every iteration, it will cause read error on the 2nd and
|
|
# 4th files.
|
|
# 7) Verify that GLOBAL.GTID_EXECUTED contains committed gtid MASTER_UUID:1
|
|
# and GLOBAL.GTID_PURGED is empty after server restarts again.
|
|
# 8) Move binary logs back.
|
|
#
|
|
# 9) PURGE BINARY LOGS TO the last binary log binlog.000006, which
|
|
# just contains a Previous_gtids_log_event. This will not cause an
|
|
# assertion failure any more.
|
|
# 10) Assert that the set of purged gtids is not empty (it is MASTER_UUID:1),
|
|
# since a gtid event is written into binlog.000004.
|
|
#
|
|
|
|
# Test in this file is binlog format agnostic, thus no need
|
|
# to rerun them for every format.
