Let TABLE_SHARE::tdc.free_tables, TABLE_SHARE::tdc.all_tables,
TABLE_SHARE::tdc.flushed and corresponding invariants be protected by
per-share TABLE_SHARE::tdc.LOCK_table_share instead of global LOCK_open.
Fixed the following compilation errors and test failures:
- maria SE: "stage_waiting_for_a_resource" wasn't declared w/o PFS
- sql_repl.h: PSI_mutex_key is not available in non-PFS builds
- mysqld.cc: pfs_param is not available in non-PFS builds
- mysqld.cc: init_show_explain_psi_keys() is not available in non-PFS builds
- mysqld.cc: call net_before_header_psi, net_after_header_psi even if PFS
is not available so that thread enters stage_init at proper time. Fixes
sp-threads and a few tests in funcs_1.
- myisam_file_io.opt: added missing loose prefix
includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
MySQL 5.6.10 performance schema: merge of the test files for the host_cache table
With this patch, all tests perfschema.hostcache_* pass.
There are still some additional unmerged minor changes to these tests
in mysql 5.6.10.
Merge of 10.0-mdev26 feature tree into 10.0-base.
Global transaction ID is prepended to each event group in the binlog.
Slave connect can request to start from GTID position instead of specifying
file name/offset of master binlog. This facilitates easy switch to a new
master.
Slave GTID state is stored in a table mysql.rpl_slave_state, which can be
InnoDB to get crash-safe slave state.
GTID includes a replication domain ID, allowing to keep track of distinct
positions for each of multiple masters.
Adjust full test suite to work with GTID.
Huge patch, mainly due to having to update .result file for all SHOW BINLOG
EVENTS and mysqlbinlog outputs, where the new GTID events pop up.
Everything was painstakingly checked to be still correct and valid .result
file updates.
-Change my_rnd() slightly to make it safer if two threads use it at the same time.
-Avoid some sprintf and strmov in vio.
-Changed thread_count to be automaticly incremented (instead of under LOCK_thread_count).
-Thread cache now uses LOCK_thread_cache instead of LOCK_thread_count.
-Moved delete thd out from LOCK_thread_count.
-Save some mysql_cond_broadcast(&COND_thread_count) calls.
-Removed call to getsockname() during connect.
-Initialize random generator without locks.
Other things:
-Fixed test cases that depends on changes for LOCK_grant
-Added thread_safe_decrement32() and thread_safe_increment32()
-Removed sql_rnd_with_mutex() and get_thread_running()
-In check_table_access() don't lock LOCK_grant if we can resolve the grant with user or db level grants (the normal case).
-Don't use a lock for setting THD->query_id.
-Fixed bug where thd->set_query_id() could be set to same value by multiple threads.
Thanks to Yoshinori Matsunobu for the benchmark of connection speed and to
Domas Mituzas for the inspiration for many of the fixes.
include/violite.h:
Change desc to a string pointer
mysql-test/suite/perfschema/r/all_instances.result:
Added new mutex
mysql-test/suite/perfschema/t/func_mutex.test:
Test for LOCK_system_variables_hash instead of LOCK_grant, as LOCK_grant is not anymore always taken for SELECT's.
mysys/my_gethwaddr.c:
More DBUG
mysys/my_rnd.c:
Change my_rnd() slightly to make it safer if two threads use it at the same time.
sql/event_scheduler.cc:

Moved some safe things out from LOCK_thread_count.
Simplify deleting of THD for running thread.
sql/mysqld.cc:
Changed thread_count to be automically incremented
Thread cache now uses LOCK_thread_cache instead of LOCK_thread_count
Added delete_running_thd()
Moved delete thd out from LOCK_thread_count
More DBUG
Only call mysql_cond_broadcast(&COND_thread_count) if thread_count is 0
Removed call to getsockname() (old not anymore needed check)
sql/mysqld.h:
Removed sql_rnd_with_mutex() (not needed anymore)
Removed not used function get_thread_running()
Added thread_safe_decrement32() and thread_safe_increment32()
Simplified dec_thread_running() and inc_thread_running()
next_query_id() should return the original value for global_query_id, not the next one.
(Bug introduced with MySQL 5.5 merge).
sql/sql_acl.cc:
In check_table_access() don't lock LOCK_grant if we can resolve the grant with user or db level grants (the normal case).
sql/sql_class.cc:
Removed thd_lock_thread_count() and thd_unlock_thread_count()
Initialize random generator without locks
Don't use a lock for setting THD->query_id.
(This is only accessed by thread owning the THD)
sql/sql_class.h:
Don't use a lock for setting THD->query_id.
sql/sql_insert.cc:
Changed thread_count to be automically incremented
sql/sql_parse.cc:
Changed thread_count to be automically incremented
Fixed bug where thd->set_query_id() could be set to same value by multiple threads.
vio/vio.c:
Don't generate 'desc' with sprintf/strmov. Assign a pointer instead.
(Good enough as this is just for debugging)
Before this fix, configuring the server with:
- performance_schema_events_waits_history_size=0
- performance_schema_events_waits_history_long_size=0
could cause a crash in the performance schema.
These settings to 0 are intended to be valid and supported,
and are in fact working properly in mysql 5.6 and up already.
This fix backports the code fix and test cases from mysql 5.6
to the mysql 5.5 release.

This was failing not only for P_S, but for any engine that had
HA_PRIMARY_KEY_REQUIRED_FOR_DELETE flag set (in the tree - only P_S and federated).
Because of this flag, read_set and write_set were (possibly) changed
on update. But later the code modified these bitmaps and restored them to the default
state, losing HA_PRIMARY_KEY_REQUIRED_FOR_DELETE related changes.
sql/handler.cc:
small optimization.
don't change the *write* set only because all columns has to be *read*
and small collateral changes
mysql-test/lib/My/Test.pm:
somehow with "print" we get truncated writes sometimes
mysql-test/suite/perfschema/r/digest_table_full.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/dml_handler.result:
host table is not ported over yet
mysql-test/suite/perfschema/r/information_schema.result:
host table is not ported over yet
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.
mysql-test/suite/perfschema/r/statement_digest.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/statement_digest_consumers.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/perfschema/r/statement_digest_long_query.result:
md5 hashes of statement digests differ, because yacc token codes are different in mariadb
mysql-test/suite/rpl/r/rpl_mixed_drop_create_temp_table.result:
will be updated to match 5.6 when alfranio.correia@oracle.com-20110512172919-c1b5kmum4h52g0ni and anders.song@greatopensource.com-20110105052107-zoab0bsf5a6xxk2y are merged

Now when a table is dropped the statistics on the table is removed
from the statistical tables. If the table is altered in such a way
that a column is dropped or the type of the column is changed then
statistics on the column is removed from the table column_stat.
It also triggers removal of the statistics on the indexes who use
this column as its component.
Added procedures that changes the names of the tables or columns
in the statistical tables for.
These procedures are used when tables/columns are renamed.
Also partly re-factored the code that introduced the persistent
statistical tables.
Added test cases into statistics.test to cover the new code.
Details:
- Archive storage engine file access were not instrumented and thus
were not shown in PS tables.
Fix:
- Added instrumentation code by using PS Apis for I/O.
