Renamed HA_VAR_LENGTH to HA_VAR_LENGTH_PART
Renamed in all files FIELD_TYPE_STRING and FIELD_TYPE_VAR_STRING to MYSQL_TYPE_STRING and MYSQL_TYPE_VAR_STRING to make it easy to catch all possible errors
Added support for VARCHAR KEYS to heap
Removed support for ISAM
Now only long VARCHAR columns are changed to TEXT on demand (not CHAR)
Internal temporary files can now use fixed length tables if the used VARCHAR columns are short
Simple optimzations and cleanups
Removed compiler warnings and fixed portability issues
Added client functions 'mysql_embedded()' to allow client to check if we are using embedded server
Fixes for purify
- mutex was unlocked before the end of the critical sesion,
- Portability issue: It's better to use (*alloc)(x) instead of alloc(x),
if alloc is a function passed as an argument.
- Use {} around if() block, to avoid possible problems with some Windows compilers.
after Monty's review.
- Item_param was rewritten.
- it turns out that we can't convert string data to character set of
connection on the fly, because they first should be written to the binary
log.
To support efficient conversion we need to rewrite prepared statements
binlogging code first.
Added new test cases for this, and adjusted old tests accordingly,
and new error codes and messages.
Fixed bugs in some tests (bug2673 and use test).
Added debug printing of instructions in SPs.
Added more DBUG statements
Ensure that we are comparing end space with BINARY strings
Use 'any_db' instead of '' to mean any database. (For HANDLER command)
Only strip ' ' when comparing CHAR, not other space-like characters (like \t)
Fixed output from mysqlbinlog when using --skip-comments
Fixed warnings from valgrind
Fixed ref_length when used with HEAP tables
More efficent need_conversion()
Fixed error handling in UPDATE with not updateable tables
Fixed bug in null handling in CAST to signed/unsigned
<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
NATIONAL CHARACTER() has latin1 charset now.
Reasons are (by Monty):
I think we should keepy having latin1 (default configure option)
as the national character set. The reason for this is simple that:
- This is ok for a large part of the world.
- It's faster and takes less space than utf8.
