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 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

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)
New class Item_func_set_collation()
Fixed that "SELECT CONVERT(expr USING charset) GROUP BY 1" was not working
New COLLATION syntax: <expr> COLLATE latin1
Changed name of variables
NO_FOREIGN_KEY_CHECKS -> FOREIGN_KEY_CHECKS
RELAXED_UNIQUE_CHECKS -> UNIQUE_CHECKS
to avoid confusion with 'not...' variables.
Write name of adminstrator command to slow log.

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
Portability fixes for HPUX
Rename of CHECK_LOCK to IS_FREE_LOCK
Apply lower_case_table_names also to databases
Cleanup of describe code
Don't allow \ in database names
new file
Client-server protocol 4.1 changes - Server side:
* Enhanced metadata information:
- SHOW [COUNT(*)] ERRORS [LIMIT [offset,] rows]
- SHOW [COUNT(*)] WARNING [LIMIT [offset,] rows]
- SHOW TABLE TYPES
- SHOW PRIVILEGES
- SHOW COLUMN TYPES (Not fully implemented)
* Prepared execution
* Long data handling in pieces
* And other misc changes
SHOW DATABASES
CREATE TEMPORARY TABLE
LOCK TABLES
REPLICATION SLAVE & REPLICATION CLIENT
SUPER
EXECUTE
All scripts & documentation is updated for this change.
Added better error messages for global privileges
Fixes in GeomFromText() to accept an new optional
argument respobsible for SRID. This is for more
OpenGIS conformance and PostGIS compatibility
to simplify migrating from PgSQL to MySQL
first pull, merge,test, and get it to work.
The main change is the new replication code - now we have two slave threads
SQL thread and I/O thread. I have also re-written a lot of the code to
prepare for multi-master implementation.
I also documented IO_CACHE quite extensively and to some extend, THD class.
Fixes for building MySQL with gcc 3.0
Added SIGNED / UNSIGNED casts
Fixed core dump bug in net_clear() with libmysqld.
Back to using semaphores in query cache.
Added 'Null' and 'Index_type' to SHOW INDEX.
One more notice:
limiting number of queries per hour for different users has been done
on 4.0.1 , but I can port it to 3.23.*
This will require only certain changes, like number of columns in user
table.
I will also make a test case for it, after it is approved by Monty,
as result file will depend on the error message text.
* multi-table updates
* new paid feature for limiting number of queries per hour for users
* optional syntax for multi-table deletes
* optimization for SQL_CALC_FOUND_ROWS
* a small addition for CREATE .. SELECT that will be of future use
I know that all this will require many additions to documentation,
which I have not done, but I am at Arjen's disposal to help him document
all this.
