- Correctly handle plan refinement stage for LooseScan plans: run create_ref_for_key() if LooseScan
plan includes a ref access, and if we don't have any fixed key components, switch to a full index scan.
* MYSQL_MAINTAINER_MODE and SAFEMALLOC take values ON/OFF/AUTO
(in all builds, in none, only in debug and platform dependent)
* ./configure prefers RelWithDebInfo unless the user overrides
Problem description:
When a view is created using function FORMAT and if FORMAT function uses locale
option,definition of view saved into server doesn't contain that locale information,
Ex:
create table test2 (bb decimal (10,2));
insert into test2 values (10.32),(10009.2),(12345678.21);
create view test3 as select format(bb,1,'sk_SK') as cc from test2;
select * from test3;
+--------------+
| cc |
+--------------+
| 10.3 |
| 10,009.2 |
| 12,345,678.2 |
+--------------+
3 rows in set (0.02 sec)
show create view test3
View: test3
Create View: CREATE ALGORITHM=UNDEFINED DEFINER=`root`@`localhost`
SQL SECURITY DEFINER VIEW `test3` AS select format(`test2`.`bb`,1) AS `cc`
from `test2`
character_set_client: latin1
collation_connection: latin1_swedish_ci
1 row in set (0.02 sec)
Problem Analysis:
The function Item_func_format::print() which prints the query string to create
the view does not print the third argument (i.e the locale information). Hence
view is created without locale information.
Problem Solution:
If argument count is more than 2 we now print the third argument onto the query string.
Files changed:
sql/item_strfunc.cc
Function call changes: Item_func_format::print()
mysql-test/t/select.test
Added test case to test the bug
mysql-test/r/select.result
Result of the test case appended here
There was memory leak when running some tests on PB2.
The reason of the failure is an early return from change_master()
that was supposed to deallocate a dyn-array.
Actually the same bug58915 was fixed in trunk with relocating the dyn-array
destruction into THD::cleanup_after_query() which can't be bypassed.
The current patch backports magne.mahre@oracle.com-20110203101306-q8auashb3d7icxho
and adds two optimizations: were done: the static buffer for the dyn-array to base on,
and the array initialization is called precisely when it's necessary rather than
per each CHANGE-MASTER as before.
mysql-test/suite/rpl/t/rpl_empty_master_host.test:
the test is binlog-format insensitive so it will be run with MIXED mode only.
mysql-test/suite/rpl/t/rpl_server_id_ignore.test:
the test is binlog-format insensitive so it will be run with MIXED mode only.
sql/sql_class.cc:
relocating the dyn-array
destruction into THD::cleanup_after_query().
sql/sql_lex.cc:
LEX.mi zero initialization is done in LEX().
sql/sql_lex.h:
Optimization for repl_ignore_server_ids to base on a static buffer
which size is chosen to fit to most common use cases.
sql/sql_repl.cc:
dyn-array destruction is relocated to THD::cleanup_after_query().
sql/sql_yacc.yy:
Refining logics of Lex->mi.repl_ignore_server_ids initialization.
The array is initialized once a corresponding option in CHANGE MASTER token sequence
is found.
Fix typo causing too low timeout value for wait_for_slave_param.inc.
Fix binlog checksums following 5.5 merge.
Make sure the rpl suite can run with --mysqld=--binlog-checksum=CRC32
Fix a number of problems in the code when checksums are enabled.
fix safemalloc to compile w/o libbfd.
CMakeLists.txt:
NOT_FOR_DISTRIBUTION option
cmake/readline.cmake:
simplify libedit/readline detection.
never use bundled libedit.
use system readline v6 only if NOT_FOR_DISTRIBUTION=1
configure.cmake:
use libbfd only if NOT_FOR_DISTRIBUTION=1
include/my_stacktrace.h:
link with libbfd even w/o safemalloc.
- Let JTBM optimization code handle the case where the subquery is degenerate and doesn't have a
join query plan. Regular materialization would fall back to IN->EXISTS for such cases. Semi-Join
materialization does not have such option, instead we introduce and use "constant JTBM join tabs".
- Do a "more thorough" cleanup of SJ-Materialization join tab in JOIN_TAB::cleanup. The bug
was due to the fact that JOIN_TAB::cleanup() may be called multiple times for the same tab
if the join has grouping.
mysql-test/suite/maria/r/maria-recovery3.result:
Added test case for recovery bug
mysql-test/suite/maria/t/maria-recovery3.test:
Added test case for recovery bug
storage/maria/ha_maria.cc:
Don't print query twice to log
storage/maria/ma_delete.c:
More DBUG_PRINT
storage/maria/ma_key_recover.c:
Added new asserts to detect errors earlier
storage/maria/ma_recovery.c:
Update all states when moving a non-transactional file to transactional. This fixes lp:887051
Added a global read-only option slow-start-timeout to control the
Windows service control manager's service start timeout, that was
currently hard-coded to be 15 seconds.
The default of the new option is 15 seconds.
The timeout can also be set to 0 (to mean no timeout applicable).
- Changed storage to be 2 bytes instead of sizeof(size_t) (simple optimization)
- Fixed bug when using query_cache_strip_comments and query that started with '('
- Fixed DBUG_PRINT() that used wrong (not initialized) variables.
mysql-test/mysql-test-run.pl:
Added some space to make output more readable.
mysql-test/r/query_cache.result:
Updated test results
mysql-test/t/query_cache.test:
Added test with query_cache_strip_comments
sql/mysql_priv.h:
Added QUERY_CACHE_DB_LENGTH_SIZE
sql/sql_cache.cc:
Fixed bug when using query_cache_strip_comments and query that started with '('
Store db length in 2 characters instead of size_t.
Get db length from correct position (earlier we had an error when query started with ' ')
Fixed DBUG_PRINT() that used wrong (not initialized) variables.
