Class for sending data from server to client (Protocol)
This handles both the old ( <= 4.0 ) protocol and then new binary protocol that is used for prepared statements.
Made keybuff_size longlong (To make show variables work similar on 32
and 64 bit systems)
Fixed some 'not initalized variable errors' in multi-table-update.
Fixed memory leak in multi-table-update.
Now all tests works under valgrind without any errors.
Fixed reference to freed memory in acl_init()/grant_init()
Fixed possible memory leak. (Could only happen in very strange circumstances)
Fixed bug in ALTER TABLE with BDB tables
Updated mysql-test for valgrind
Warning handling and initial prepared statement handling (last not complete yet)
Changed a lot of functions that returned 0/1 to my_bool type.
GRANT handling now uses read/write locks instead of mutex
Change basic net functions to use THD instead of NET
(needed for 4.1 protocol)
Use my_sprintf instead of sprintf() + strlen()
Added alloc_query() to be able to chare query initialization code with
prepared statements.
Cleanup handling of SHOW COUNT(*) WARNINGS and SELECT LAST_INSERT_ID()
Note that the following test fails (will be fixed ASAP):
sub_select, union, rpl_rotate_logs and rpl_mystery22
Fixed bug in SELECT ... ORDER BY ... LIMIT
Fixed bug in ALTER TABLE and RENAME TABLE with --lower-case-table-names
Fixed hang when using --with-openssl
Fixed that GRANT ... REQUIRE options are not forgot when doing new GRANT
Changed fn_ext to point at first '.' after directory.
FLUSH LOGS removed numerical extension for all future update logs.
Fixed the mysqld --help reports right values for --datadir and --bind-address
--log-binary=a.b.c now properly strips of .b.c
Fix that one can DROP UDF functions that was not loaded at startup
Made AND optional in REQUIRE
Added REQUIRE NONE
Some simple optimzations, more comments and indentation changes.
Add ` around database in 'use database' in binary log.
Moved max_error_count and max_warning_count to variables struct.
Removed SHOW_WARNS_COUNT and SHOW_ERRORS_COUNT calls.
Changed string functions to use character set of first string argument as default return characterset
(Each string function can change the above assumption if needed)
Changed option variables to my_bool (to avoid bugs in my_getopt())
Added new thread specific mutex LOCK_delete to be able to free LOCK_thread_count early.
Changed usage of LOCK_thread_count -> LOCK_status for statistics variables
Fixed bugs in my last changeset that made MySQL hard to compile.
Added mutex around some data that could cause table cache corruptions when using OPTIMIZE TABLE / REPAIR TABLE or automatic repair of MyISAM tables.
Added mutex around some data in the slave start/stop code that could cause THD linked list corruptions
Extended my_chsize() to allow one to specify a filler character.
Extend vio_blocking to return the old state (This made some usage of this function much simpler)
Added testing for some functions that they caller have got the required mutexes before calling the function.
Use setrlimit() to ensure that we can write core file if one specifies --core-file.
Added --slave-compressed-protocol
Made 2 the minimum length for ft_min_word_len
Added variables foreign_key_checks & unique_checks.
Less logging from replication code (if not started with --log-warnings)
Changed that SHOW INNODB STATUS requre the SUPER privilege
More DBUG statements and a lot of new code comments
New fields in CHARSET_INFO for more nice SHOW CHARACTER SET
Dynamic charsets are now handled in faster way
SHOW CHARACTER SET now displays not only compiled charsets but dynamic charsets too
Made a some new buffers thread specific and changeable.
Resize of key_buffer.
AUTO_COMMIT -> AUTOCOMMIT
Fixed mutex bug in DROP DATABASE
Fixed bug when using auto_increment as second part of a key where first part could include NULL.
Split handler->extra() to extra() and extra_opt() to be able to support thread specific buffers.
Don't write message to error log when slave reconnects becasue of timeout.
Fixed possible update problem when using DELETE/UPDATE on small tables
(In some cases we used index even if table scanning would be better)
A lot of minior code cleanups
