mysql-test/suite/perfschema/r/nesting.result:
this differs, because we don't rewrite general log queries, and multi-statement
packets are logged as a one entry. this result file is identical to what mysql-5.6.5
produces with the --log-raw option.
mysql-test/suite/perfschema/r/relaylog.result:
MariaDB modifies the binlog index file directly, while MySQL 5.6 has a feature "crash-safe binlog index" and modifies a special "crash-safe" shadow copy of the index file and then moves it over. That's why this test shows "NONE" index file writes in MySQL and "MANY" in MariaDB.
mysql-test/suite/perfschema/r/server_init.result:
MariaDB initializes the "manager" resources from the "manager" thread, and starts this thread only when --flush-time is not 0. MySQL 5.6 initializes "manager" resources unconditionally on server startup.
mysql-test/suite/perfschema/r/stage_mdl_global.result:
this differs, because MariaDB disables query cache when query_cache_size=0. MySQL does not
do that, and this causes useless mutex locks and waits.

Introduce a new storage engine API method commit_checkpoint_request().
This is used to replace the fsync() at the end of every storage engine
commit with a single fsync() when a binlog is rotated.
Binlog rotation is now done during group commit instead of being
delayed until unlog(), removing some server stall and avoiding an
expensive lock/unlock of LOCK_log inside unlog().
BUG#11761686 insert_id event is not filtered.
Two issues are covered.
INSERT into autoincrement field which is not the first part in the composed primary key
is unsafe by autoincrement logging design. The case is specific to MyISAM engine
because Innodb does not allow such table definition.
However no warnings and row-format logging in the MIXED mode was done, and
that is fixed.
Int-, Rand-, User-var log-events were not filtered along with their parent
query that made possible them to screw up execution context of the following
query.
Fixed with deferring their execution until the parent query.

PROBLEM: After WL 4144, when using MyISAM Merge tables, the routine
open_and_lock_tables will append to the list of tables to lock, the
base tables that make up the MERGE table. This has two side-effects in
replication:
1. On the master side, we log additional table maps for the base
tables, since they appear in the list of locked tables, even
though we don't really use them at the slave.
2. On the slave side, when opening a MERGE table while applying a
ROW event, additional tables are appended to the list of tables
to lock.
Side-effect #1 is not harmful. It's just that when using MyISAM Merge
tables a few table maps more may be logged.
Side-effect #2, is harmful, because the list rli->tables_to_lock is an
extended structure from TABLE_LIST in which the extra fields are
filled from the table maps that are processed. Since
open_and_lock_tables appends tables to the list after all table map
events have been processed we end up with entries without
replication/table map data on them. Thus when trying to access that
info for these extra tables, the server will crash.
SOLUTION: We fix side-effect #2 by making sure that we access the
replication part of the structure for those in the list that were
accounted for when processing the correspondent table map events. All
in all, we never go beyond rli->tables_to_lock_count.
We also deploy an assertion when clearing rli->tables_to_lock, making
sure that the base tables are not in the list anymore (were closed in
close_thread_tables).
Problem : The basic problem is the way the thread sleeps in mysql-5.5 and also in mysql-5.1
when we execute a stop slave on windows platform.
On windows platform if the stop slave is executed after the master dies, we have
this long wait before the stop slave return a value. This is because there is a
sleep of the thread. The sleep is uninterruptable in the two above version,
which was fixed by Davi patch for the BUG#11765860 for mysql-trunk. Backporting
his patch for mysql-5.5 fixes the problem.
Solution : A new pair of mutex and condition variable is introduced to synchronize thread
sleep and finalization. A new mutex is required because the slave threads are
terminated while holding the slave thread locks (run_lock), which can not be
relinquished during termination as this would affect the lock order.
mysql-test/suite/rpl/r/rpl_start_stop_slave.result:

SCAN/CPU) => SLAVE FAILURE
When a statement containing a large amount of ROWs to be applied on
the slave, and the slave's table does not contain a PK, it can take a
considerable amount of time to find and change all the rows that are
to be changed.
The proper slave enhancement will be implemented in WL 5597. However,
in this bug we are making it clear to the user what the problem is, by
printing a message to the error log if the execution time, for a given
statement in RBR, takes more than LONG_FIND_ROW_THRESHOLD (set to 60
seconds). This shall help the DBA to diagnose what's happening when
facing a slave server that is quiet for no apparent reason...
The note is only printed to the error log if log_warnings is set to be
greater than 1.
sql/log_event.cc:
Core of the patch.
In Rows_log_event::do_apply_event, sets STMT start
timestamp.
In Rows_log_event::find_row, if a PK is not used, then the start
timestamp is checked to see if the time spent on this STMT is enough
to justify the printing of a note (only if it was not printed before).

Changed from my_getsystime() to set_timespec_time_nsec()
storage/maria/ma_loghandler.c:
Changed from my_getsystime() to my_hrtime()
storage/maria/ma_recovery.c:
Changed from my_getsystime() to mmicrosecond_interval_timer()
storage/maria/unittest/trnman-t.c:
Changed from my_getsystime() to mmicrosecond_interval_timer()
storage/xtradb/handler/ha_innodb.cc:
Added support for new time,datetime and timestamp
unittest/mysys/thr_template.c:
my_getsystime() -> my_interval_timer()
unittest/mysys/waiting_threads-t.c:
my_getsystime() -> my_interval_timer()
In RBR and in case of converting blob fields, the space allocated
while unpacking into the conversion field was not freed after
copying from it into the real field.
We fix this by freeing the conversion field when the conversion
table is not needed anymore (on close_tables_to_lock).
Changed test suite to use --log-basename (to get the code tested)
Added --sync-sys=1 to test suite to speed it up.
Better error messages if something goes wrong with mysql_install_db
mysql-test/Makefile.am:
Removed not existing directory
mysql-test/lib/My/ConfigFactory.pm:
Use log-basename
We had to also set 'log_error' as some test was explicitely using the old name
Added 'sync-sys=1' to speed up test suite
mysql-test/r/variables-notembedded.result:
Updated test results (variable relay_log is now set)
mysql-test/suite/binlog/t/binlog_delete_and_flush_index-master.opt:

mysql-test/suite/binlog/t/binlog_stm_unsafe_warning-master.opt:
Force specific names for some log files.
mysql-test/suite/binlog/t/binlog_stm_unsafe_warning.test:

More information to --help
Write url to knowledge base if something goes wrong
Fail at once if we can't create a database directory (no reason to continue and write a screenful of not related text)
scripts/mysqld_safe.sh:
Also allow one to use --data for --datadir (common shortening)
Added support for --log-basename
Fail at once if we can't create a log directory
Fixed bug where we used a pid file name without '.pid' extension
sql/log.cc:
Create a log file name trough my_once_alloc() (To get it automaticly freed at exit)
sql/mysql_priv.h:
Added new prototype
sql/mysqld.cc:
Added support for --log-basename
Better help for a lot of log-filename related variables.
sql/rpl_rli.cc:
Write information that one can use --log-basename
sql/set_var.cc:
Add log_basename as a readonly variable
Before this fix, all the performance schema instrumentation for both the binary log
and the relay log would use the following instruments:
- wait/io/file/sql/binlog
- wait/io/file/sql/binlog_index
- wait/synch/mutex/sql/MYSQL_BIN_LOG::LOCK_index
- wait/synch/cond/sql/MYSQL_BIN_LOG::update_cond
This instrumentation is too general and can be more specific.
With this fix, the binlog instrumentation is identical,
and the relay log instrumentation is changed to:
- wait/io/file/sql/relaylog
- wait/io/file/sql/relaylog_index
- wait/synch/mutex/sql/MYSQL_RELAY_LOG::LOCK_index
- wait/synch/cond/sql/MYSQL_RELAY_LOG::update_cond
With this change, the performance instrumentation for the binary log and the relay log,
which share the same structure but have different uses, is more detailed.
This is especially important for hosts in the middle of a replication chain,
that are both masters (binlog) and slaves (relaylog).
and collateral changes.
