fixed IN subselect with basic constant left expression
SQLCOM_CREATE_TABLE, SQLCOM_UPDATE_MULTI, SQLCOM_REPLACE_SELECT, SQLCOM_INSERT_SELECT, QLCOM_DELETE_MULTI fixed to be compatible with PS (BUG#3398, BUG#3406)
fixed multiupdate privelege check (BUG#3408)
fixed multiupdate tables check (BUG#3411)
unchecked commands now is rejected by PS protocol to avoid serever crash
fixed cleunup procedure to be compatible sith DO/SET (BUG#3393)
Fixed bugs in group_concat with ORDER BY and DISTINCT (Bugs #2695, #3381 and #3319)
Fixed crash when doing rollback in slave and the io thread catched up with the sql thread
Set locked_in_memory properly
that it tested the privilege in ::update() whereas it should be
in ::check() (see email from Serg, subject
"Re: bk commit - 4.1 tree (guilhem:1.1706)").
So I add instead a check_func function to sys_var_thd_bit.
I do the same addition to sys_var_thd_ulong, to unify handling
of PSEUDO_THREAD_ID with the one of SQL_LOG_BIN. So class
sys_var_pseudo_thread_id is not needed anymore, removing it.
re-using unused LOCK_active_mi to serialize all administrative
commands related to replication:
START SLAVE, STOP SLAVE, RESET SLAVE, CHANGE MASTER, init_slave()
(replication autostart at server startup), end_slave() (replication
autostop at server shutdown), LOAD DATA FROM MASTER.
This protects us against a handful of deadlocks (like BUG#2921
when two START SLAVE, but when two STOP SLAVE too).
Removing unused variables.
Allow one to force lower_case_table_names to 0, even if the file system is case insensitive. This fixes some issues on Mac OS X (Bug #2994)
Added variables "lower_case_file_system", "version_compile_os" and "license"
Don't show PSEUDO_THREAD_ID in SHOW VARIABLES because:
- we don't want people to discover this variable as it could never do good to
set it (it was designed for use by mysqlbinlog only, so that a thread can have
several temp tables of the same name at the same time)
- if we show it in SHOW VARIABLES, Mysql Administrator will display it and
this will force us to put a description, so all MySQL Administrator user
will be aware of this variable, some may have the idea to set it with a SET
command, and then it will cause bad things.
The variable is still settable, and still visible with SELECT @@.
Added support for lower_case_table_names=2, which is to be used on case insensitive file systems.
This tells MySQL to preserve the used case of filenames and database names to make it esier to move files between cases sensitive can case insensitive file systems (like Windows and Linux)
Cleaned up embedded library access and query cache handling
Changed min stack size to 128K (to allow longer MyISAM keys)
Fixed wrong priority for XOR (should be less than NEG to get -1^1 to work)
Fixed compiler warnings (a lot of hidden variables detected by the Forte compiler)
Added a lot of 'version_xxx' strings to 'show variables'
Prevent copying of TMP_TABLE_PARAM (This caused core dump bug on Solaris)
Fixed problem with printing sub selects to debug log
New multi-key-cache handling. This was needed becasue the old one didn't work reliable with MERGE tables.
ALTER TABLE table_name ... CHARACTER SET ... now changes all char/varchar/text columns to the given character set
(One must use ALTER TABLE ... DEFAULT CHARACTER SET ... to change the default character set)
Fixed that have_compress is detected properly (fixes problems with func_compress.test on platforms without zlib)
New syntax for CACHE INDEX ('keys' is optional if no index name is given and one mentions the key cache name only ones)
Removed compiler warnings
Added mysql_set_server_option() to allow clients like PHP to easaily set/reset the multi-statement flag.
Cleaned up (and disabled part of) date/time/datetime format patch. One can't anymore change default read/write date/time/formats.
This is becasue the non standard datetime formats can't be compared as strings and MySQL does still a lot of datetime comparisons as strings
Changed flag argument to str_to_TIME() and get_date() from bool to uint
Removed THD from str_to_xxxx functions and Item class.
Fixed core dump when doing --print-defaults
Move some common string functions to strfunc.cc
Dates as strings are now of type my_charset_bin instead of default_charset()
Introduce IDENT_QUOTED to not have to create an extra copy of simple identifiers (all chars < 128)
Removed xxx_FORMAT_TYPE enums and replaced them with the old TIMESTAMP_xxx enums
Renamed some TIMESTAMP_xxx enums to more appropriate names
Use defines instead of integers for date/time/datetime string lengths
Added to build system and use the new my_strtoll10() function.
query_alloc_block_size, query_prealloc_size, range_alloc_block_size,transaction_alloc_block_size and transaction_prealloc_size
Add more checks for "out of memory" detection in range optimization
Multiple tablespaces for InnoDB
sql_table.cc:
Tell explicitly that InnoDB should retrieve all columns in CHECKSUM TABLE
sql_update.cc, sql_select.cc, my_base.h:
More descriptive flag name HA_EXTRA_RETRIEVE_ALL_COLS
WL#604 Privileges in embedded library
code added to check privileges in embedded library
NO_EMBEDDED_ACCESS_CHECKS macros inserted in code so we can exclude
access-checking parts. Actually we now can exclude these parts from
standalone server as well. Do we need it?
Access checks are disabled in embedded server by default. One should
edit libmysqld/Makefile manually to get this working.
We definitely need the separate configure for embedded server
embedded library
some dirty places cleaned:
uint removed from mysql.h as Miguel suggested
empty_string renamed as my_empty_string to get rid of name's intersections
using embedded library
Added key cache parameters for midpoint insertion strategy
Many files:
Added midpoint insertion strategy for key cache
mi_test2.c:
Added a parameter to resize_key_cache
--old-passwords
Support for option --old-protocol was removed.
Some test performed.
Tests for SSL and replication are pending.
More strict following to specification for --old-passwords
is in the TODO.
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
collation_client -> character_set_client
collation_results -> character_set_results
character_set -> character_set_server
SET NAMES now doesn't start client->server conversion
SET CHARACTER SET now starts both client->server and server->client conversion
