With combination of --log-bin and Galera the server may crash reporting two characteristic stacks: /usr/sbin/mysqld(_ZN13MYSQL_BIN_LOG13mark_xid_doneEmb+0xc7)[0x7f182a8e2cb7] /usr/sbin/mysqld(binlog_background_thread+0x2b5)[0x7f182a8e3275] or /usr/sbin/mysqld(_ZN13MYSQL_BIN_LOG21do_checkpoint_requestEm+0x9d)[0x7ff395b2dafd] /usr/sbin/mysqld(_ZN13MYSQL_BIN_LOG20checkpoint_and_purgeEm+0x11)[0x7ff395b2db91] /usr/sbin/mysqld(_ZN13MYSQL_BIN_LOG16rotate_and_purgeEb+0xc2)[0x7ff395b300b2] The reason of the failure appears to be non-matching decrements for `xid_count_per_binlog::xid_count` which can occur when a transaction is executed having its connection issued `SET @@sql_log_bin=0`. In such case the xid count is not incremented but its decrements still runs to turn `binlog_xid_count_list` into improper state which the following FLUSH BINARY LOGS exposes through the crash. *Note_1*: the regression test reuses an existing galera.sql_log_bin which does not run stably (even in its base form) by mtr with --log-bin. *Note_2*: 10.0-galera branch is free of this issue having missed MDEV-7205 fixes. |
