It is triple bug with one test suite:
1. Incorrect outer table detection
2. Incorrect leaf table processing for multi-update (should be full like for usual updates and inserts)
3. ON condition fix_fields() fould be called for all tables of the query.
Both bugs are caused by the same problem: the function optimize_cond() should
update the value of *cond_equal rather than the value of join->cond_equal,
because it is called not only for the WHERE condition, but for the HAVING
condition as well.
Revert the old patch revid:monty@askmonty.org-20100325133339-7mkel6valai0b4lb
This patch caused the InnoDB part of the transaction to not be marked
read-write in some cases, which messes up XA commit (and likely other
stuff as well).
- With big_tables=ON, materialized table will use Aria (or MyISAM) SE, which
allows prefix key reads. However, the temp.table has rec_per_key=NULL which
causes the optimizer to crash when attempting to read index statistics for a
prefix index read.
- Fixed by providing a rec_per_key array with zeros (i.e. "no statistics data")
The calls of the function remove_eq_conds() may change the and/or structure
of the where conditions. So JOIN::equal_cond should be updated for non-recursive
calls of remove_eq_conds().
- Table locks now ends with state "After table lock"
- Open table now ends with state "After opening tables"
- All calls to close_thread_tables(), not only from mysql_execute_command(), has state "closing tables"
- Added state "executing" for mysql admin commands, like CACHE INDEX, REPAIR TABLE etc.
- Added state "Finding key cache" for CACHE INDEX
- Added state "Filling schema table" when we generate temporary table for SHOW commands and information schema.
Other things:
Add limit from innobase for thread_sleep_delay. This fixed a failing tests case.
Added db.opt to support-files to make 'make package' work
mysql-test/suite/funcs_1/datadict/processlist_val.inc:
Use new state
mysql-test/suite/funcs_1/r/processlist_priv_no_prot.result:
Updated test result because of new state
mysql-test/suite/funcs_1/r/processlist_val_no_prot.result:
Updated test result because of new state
sql/CMakeLists.txt:
Have option files in support-files
sql/lock.cc:
Added new state 'After table lock'
sql/sql_admin.cc:
Added state "executing" and "Sending data" for mysql admin commands, like CACHE INDEX, REPAIR TABLE etc.
Added state "Finding key cache"
sql/sql_base.cc:
open tables now ends with state "After table lock", instead of NULL
sql/sql_parse.cc:
Moved state "closing tables" to close_thread_tables()
sql/sql_show.cc:
Added state "Filling schema table" when we generate temporary table for SHOW commands and information schema.
storage/xtradb/buf/buf0buf.c:
Removed compiler warning
storage/xtradb/handler/ha_innodb.cc:
Add limit from innobase for thread_sleep_delay. This fixed a failing tests case.
support-files/db.opt:
cmakes needs this to create data/test directory
The problem was that on opening all tables TL_WRITE, than local tables which is not updated set to TL_READ, but underlying tables of MyISAMmrg left untouched.
Prartition engine has not this problem.
All cases where lock_type assigned is not changed because call of virtual function is not cheap.
Fixed crashing bug for union queries where there was no real tables.
mysql-test/r/group_by.result:
Added test case
mysql-test/t/group_by.test:
Added test case
sql/db.opt:
Removed genrated file
sql/item.cc:
Handled case when table_list->pos_in_tables is not set. Can only happens when there is no real tables in query
The fill_schema_table() function used to call get_table_share() for a table name in WHERE
then clear the error list. That way plugins receive the superfluous error notification if it
happens in it. Also the problem was that error handler didn't prevent the suppressed
error message from logging anyway as the logging happens in THD::raise_condition
before the handler call.
Trigger_error_handler is remade into Warnings_only_error_handler, so it stores the error
message in all cases in the thd->stmt_da.
Then later the stored error is raised.
If a prepared statement calls an stored procedure,
the thd->server_status out of the SP goes up
to the PS and then to the client. So that the
client gets the SERVER_STATUS_CURSOR_EXISTS status
if the SP uses a cursor. Which makes the embedded
server fail.
Fixed by saving/restoring the upper-level server_status
in sp_head::execute().
The function Protocol::net_store_data(a, b, CHARSET_A, CHARSET_B) should
be adapted to be working in the embedded server as it's done
with the Protocol::net_store_data(a, b).
That new function renamed as net_store_data_cs, so we can make it
virtual.
