Note: The following tests fails
- fulltext (Sergei has promised to fix)
- rpl_charset (Guilhem should fix)
- rpl_timezone (Dimitray has promised to fix)
Sanja needs to check out the calling of close_thread_tables() in sp_head.cc
Post-merge fixes for nested joins.
The join_tab_cmp function in sql_select has been changed.
join_nested.result:
Post-merge fixes for nested joins.
The join_tab_cmp function in sql_select has been changed
sql_select.cc:
Post-merge fixes for nested joins.
Avoided re-execution of eliminate_not_funcs and simplify_joins
in optimize_cond.
Changed the join_tab_cmp function to take into account
the dependent relation.
sql_lex.cc, sql_lex.h:
Added the first_cond_optimization flag to st_select_lex to avoid
re-execution of some optimizations in optimize_cond.
sql_base.cc:
Post-merge fixes for nested joins.
Fixed problems with a proper column list substituted for '*' in
queries with natural joins.
If cost(full_scan_on_shortest_covering_index) < cost(best_range_scan) < cost(full_table_scan)
use full_scan_on_shortest_covering_index
(before this fix best_range_scan was used)
Added basic per-thread time zone functionality (based on public
domain elsie-code). Now user can select current time zone
(from the list of time zones described in system tables).
All NOW-like functions honor this time zone, values of TIMESTAMP
type are interpreted as values in this time zone, so now
our TIMESTAMP type behaves similar to Oracle's TIMESTAMP WITH
LOCAL TIME ZONE (or proper PostgresSQL type).
WL#1266 "CONVERT_TZ() - basic time with time zone conversion
function".
Fixed problems described in Bug #2336 (Different number of warnings
when inserting bad datetime as string or as number). This required
reworking of datetime realted warning hadling (they now generated
at Field object level not in conversion functions).
Optimization: Now Field class descendants use table->in_use member
instead of current_thd macro.
<monty> ramil, in MySQL/MyISAM we should only strip end space, not 'space-like' characters.
<monty> This is according to SQL; When doing a comparision end space and only end space are ignored.
bmove_allign -> bmove_align
Added OLAP function ROLLUP
Split mysql_fix_privilege_tables to a script and a .sql data file
Added new (MEMROOT*) functions to avoid calling current_thd() when creating some common objects.
Added table_alias_charset, for easier --lower-case-table-name handling
Better SQL_MODE handling (Setting complex options also sets sub options)
New (faster) assembler string functions for x86
Fix for LEFT/RIGHT/MID with multi-byte-character sets (bug 314)
Fix for new bison 1.875
max_insert_delayed_threads and delayed_insert_timeout now works as documented (bug 211)
Don't show port in SHOW PROCESSLIST for system threads
Fix problem with ORDER BY being discarded for some DISTINCT queries (bug 275)
Fixed bug with NATURAL LEFT JOIN, NATURAL RIGHT JOIN and RIGHT JOIN when
using many joined tables (Bug 212)
Changed timestamp to return string in YYYY-MM-DD HH:MM:SS format.
DATE_ADD() and related functions now returns correct DATE/DATETIME type depending on argument types.
Now all tests passes, still some work left to remove warnings in log files from mysql-test-run
LIMIT clause when filesort had to be used.
In that case LIMIT was applied to filesort of one of the tables,
although it could not be.
This fix solved problems with LEFT JOIN too...
Added bug fix from 3.23 for AIX 4.3.3 and gcc 3.x
Small change in EXCHANGE output
Propagate open-files-limit from mysqld_safe -> mysqld
Fixed speed bug in GROUP BY
Added quotes around database name in CREATE DATABASE db_name (for binary log)
