Patch and test case by Patryk Pomykalski
mysql-test/suite/innodb/r/innodb-autoinc.result:
updated test case
storage/innodb_plugin/handler/ha_innodb.cc:
Fixed that we properly reserve values for auto_increment
storage/xtradb/handler/ha_innodb.cc:
Fixed that we properly reserve values for auto_increment
include/mysql_com.h:
remove "shutdown levels" that aren't shutdown levels from mysql_enum_shutdown_level
mysys/my_addr_resolve.c:
my_snprintf in 5.5 (but not in 5.3) supports %p
sql/item_func.cc:
use a method (that exists only in 5.5) instead of directly accessing a member
sql/item_subselect.cc:
use a method (that exists only in 5.5) instead of directly accessing a member
sql/opt_subselect.cc:
use a method (that exists only in 5.5) instead of directly accessing a member
sql/sql_select.cc:
use a method (that exists only in 5.5) instead of directly accessing a member
mysys/thr_lock.c:
Ensure that all locks are marked as TL_UNLOCK in case of error (Safety fix)
sql/lock.cc:
Ensure that all locks are marked as TL_UNLOCK in case of error
(This is the real fix for lp:963603)
- Fix equality propagation to work with SJM nests and OR clauses (full descirption of problem and
solution in the comment in the patch)
(The second commit with post-review fixes)
- Use native memcmp() supplied with C runtime instead of hand-unrolled loop ptr_compare_N loop
Prior to fix ptr_compare_0() has 3.7% samples in OLTP-RO in-memory.
Fix brings this down to 1.8% (all memcmp samples)
- Innodb : fix UT_RELAX_CPU to be defined as YieldProcessor, as was also originally intended
(but intention was lost in the #ifdef maze
This reduces number of ut_delay() samples in profile from 1.5% to 0.5%
- The problem was that
= we've picked a LooseScan that used full index scan (tab->type==JT_ALL) on certain index.
= there was also a quick select (tab->quick!=NULL), that used other indexes.
= some old code assumes that (tab->type==JT_ALL && tab->quick) -> means that the
quick select should be used, which is not true.
Fixed by discarding the quick select as soon as we know we're using LooseScan
without using the quick select.
modified for MySQL 5.5. Logger service moved to the
plugin/sql_errlog directory to be properly used later.
plugin/sql_errlog/sql_errlog.c:
Fixes for bugs #956427 (SQL_ERROR_LOG plugin produces bogus warnings about sql-error-log-size-limit value) and #956463 (Server crashes if SQL_ERROR_LOG fails to initialize) they're also MDEV-184 and MDEV-183
The sql_error_log_deinit() should be prepared for the logger_file to be NULL.
The logger_file_size_limit upper limit wasn't properly set.
- Don't call update_virtual_fields() if table->vfield is not set
- Don't prealloc memory for in open_tables() as this is very seldom used.

sql/sql_table.cc:
Don't call update_virtual_fields() if table->vfield is not set
sql/sql_update.cc:
Don't call update_virtual_fields() if table->vfield is not set
sql/table.cc:
Assert if update_virtual_fields is called with wrong parameters
- Remove all references of MAX_TABLES from JOIN struct and make these dynamic
- Updated Join_plan_state to allocate just as many elements as it's needed
sql/opt_subselect.cc:
Optimized version of Join_plan_state
sql/sql_select.cc:
Set join->positions and join->best_positions dynamicly
Don't call update_virtual_fields() if table->vfield is not set.
sql/sql_select.h:
Remove all references of MAX_TABLES from JOIN struct and Join_plan_state and make these dynamic
- Optimize away calls to hp_rec_hashnr() by cashing hash
- Try to get more rows / block (to minimize overhead of HP_PTRS) in HEAP tables.
storage/heap/_check.c:
Optimize away calls to hp_rec_hashnr() by cashing hash.
Print cleanups
storage/heap/heapdef.h:
Added place to hold calculated hash value for row
storage/heap/hp_create.c:
Try to get more rows / block (to minimize overhead of HP_PTRS)
storage/heap/hp_delete.c:
Optimize away calls to hp_rec_hashnr() by cashing hash.
storage/heap/hp_hash.c:
Optimize away calls to hp_rec_hashnr() by cashing hash.
Remove some not needed DBUG_PRINT

Remove duplicated code
More DBUG_PRINT
storage/maria/ma_create.c:
More DBUG_PRINT
suppress these harmless but confusing warnings.
fix the program name (MY_INIT) in mysqldump
client/mysqldump.c:
for backward compatibility, prefix mysqldump error messages with "mysqldump", not with the full path of the executable
If the first component of a ref key happened to be a constant appeared
after constant row substitution then no store_key element should be
created for such a component. Yet create_ref_for_key() erroneously could
create such an element that caused construction of invalid ref keys and
wrong results for some joins.
mark the corresponding I_S table as OPTIMIZE_I_S_TABLE, to let the I_S optimizer
figure out whether files need to be opened, and don't open the tables unless
I_S optimizer says so.
