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
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
New faster list iterators
Change list code to be simpler and faster
Optimize count(distinct)
New error messages for UNION
Make create_tmp_table more general to be usable by UNION
fixed concurrency bug with a very quickly disconnecting client -
the client could disconnect and delete thd before pthread_create
could write to &thd->real_id
sql/sql_list.h
while tracking down the bug, made new/delete go through my_malloc/my_free
for ilink - did not help, but this is better anyway - cleaner exit with a message in
out of memory codition at least.
