################################################################################ # Bug#19855907 IO THREAD AUTHENTICATION ISSUE WITH SOME CHARACTER SETS # Problem: IO thread fails to connect to master if servers are configured with # special character sets like utf16, utf32, ucs2. # # Analysis: MySQL server does not support few special character sets like # utf16,utf32 and ucs2 as "client's character set"(eg: utf16,utf32, ucs2). # When IO thread is trying to connect to Master, it sets server's character # set as client's character set. When Slave server is started with these # special character sets, IO thread (a connection to Master) fails because # of the above said reason. # # Fix: If server's character set is not supported as client's character set, # then set default's client character set(latin1) as client's character set. ############################################################################### --source include/not_group_replication_plugin.inc --source include/master-slave.inc CREATE TABLE t1(i VARCHAR(20)); INSERT INTO t1 VALUES (0xFFFF); --sync_slave_with_master --let diff_tables=master:t1, slave:t1 --source include/diff_tables.inc # Cleanup --connection master DROP TABLE t1; --source include/rpl_end.inc
