MTR drops the datadir in the event of a test failure. In case mysqld
is running as a Galera node and a failure occurs while the SST is in
progress, the rsync pid file gets removed as part of the cleanup and
wsrep_sst_rsync, which relies on this file, fails to kill the rsync.
Fixed by using the cached $RSYNC_REAL_PID to kill rsync daemon.
Patch from Daniel Black:
- Change the charset of mysql.column_stats.{min_value, max_value} from
utf8_bin varchar to varbinary
- Adjust the code that saves/reads the data accordingly.
- Also provide upgrade statement in mysql_system_tables_fix.sql
mysql_secure_installation used incorrect path while looking up for "mysql"
client tool: $basedir/$basedir/bin instead of $basedir/bin.
This patch adapts "my_print_defaults" lookup algorithm for "mysql" client tool.
new features:
set event_scheduler=ON|OFF will now try to init event scheduler
if it's not enabled
set event_scheduler=default will try to enable it based on
the value of the event_scheduler when mysqld was started
1. Passes wsrep_sst_auth_value to SST scripts via WSREP_SST_OPT_AUTH envronmental variable, so it never appears on the command line
2. In mysqldump and xtrabackup* SST scripts which rely on MySQL authentication, instead of passing password on the command line, SST script sets MYSQL_PWD environment variable, so that password also never appears on the mysqldump/innobackupex command line.
- LP1380697: wsrep_sst_xtrabackup-v2 doesn't stop when mysql is SIGKILLed. (full fix for this (as engineeered by Percona) requires Linux-specific patch that we don't carry, but keep xtrabackup scripts as close as possible)
- LP1399134: Log the innobackupex/SST logs in SST to syslog if possible. (fixed)
- LP1405668: Race condition between donor and joiner in PXB SST. (fixed)
- LP1405985: Fail early if xtrabackup_checkkpoints is missing. (fixed)
- LP1407599: wsrep_sst_xtrabackup-v2 script causes innobackupex to print a false positive stack trace into the log. (fixed)
- LP1441762: IST Fails with SST script error. (fixed)
- LP1451670: Fail when move-back fails in xtrabackup SST. (fixed)

Let mysqld_safe_syslog.cnf force disable error log so that logging to syslog is
not affected by previous log_error setting.
Added handling of --skip-log-error to mysqld_safe.
in cmake tests let's treat clang like gcc (same options,
same builtins) in many cases.
* don't check the compiler when
* testing for -fvisibility=hidden support
* testing for HAVE_ABI_CXA_DEMANGLE
* testing for HAVE_GCC_ATOMIC_BUILTINS
* when removing options with string(replace)
* when running ${CC} --version (ignore the error instead)
* run ABI checks for clang
* use "canonical" gcc flags for clang
* fix groonga too
Also:
* add cmake detection for gcc __atomic_* builtins. they might be
supported (__ATOMIC_SEQ_CST is defined), but not for all operand
sizes. In particular, 64-bit atomic load is problematic on i386
* cache check results for Windows
* remove the test for HAVE_CXXABI_H (HAVE_ABI_CXA_DEMANGLE is
suffifient)
* improves MySQL client version check making it no less than required as opposed to exactly as required.
* adds event table copying to ensure same results as with rsync SST.
Removed 'galera-sst-mode' option from mysqldump and added logic
in wsrep_sst_mysqldump script to retrieve gtid_binlog_state from
donor node and send it to the joiner node.
