columns (default datatype value is assigned).
The mysql_update function has been modified to generate
an error when trying to set a NOT NULL field to NULL rather than a warning
in the set_field_to_null_with_conversions function.
- Reorganize collect a little to make it easier to apply optimizations
and settings to collected test cases.
- Add suite/rpl/combination file
- Rename include/set_binlog_format_x.inc to .sql since thay are run by "mysql"
only on some occasions
Referencing an element from the SELECT list in a WHERE
clause is not permitted. The namespace of the WHERE
clause is the table columns only. This was not enforced
correctly when resolving outer references in sub-queries.
Fixed by not allowing references to aliases in a
sub-query in WHERE.
The problem is that DROP TABLE and other DDL statements failed to
automatically close handlers associated with tables that were marked
for reopen (FLUSH TABLES).
The current implementation fails to properly discard handlers of
dropped tables (that were marked for reopen) because it searches
on the open handler tables list and using the current alias of the
table being dropped. The problem is that it must not use the open
handler tables list to search because the table might have been
closed (marked for reopen) by a flush tables command and also it
must not use the current table alias at all since multiple different
aliases may be associated with a single table. This is specially
visible when a user has two open handlers (using alias) of a same
table and a flush tables command is issued before the table is
dropped (see test case). Scanning the handler table list is also
useless for dropping handlers associated with temporary tables,
because temporary tables are not kept in the THD::handler_tables
list.
The solution is to simple scan the handlers hash table searching
for, and deleting all handlers with matching table names if the
reopen flag is not passed to the flush function, indicating that
the handlers should be deleted. All matching handlers are deleted
even if the associated the table is not open.
Bug#31610 Remove outdated and redundant tests:
partition_02myisam partition_03ndb
Bug#32405 testsuite parts: partition_char_myisam wrong content
and cleanup of testsuite
- remove/correct wrong comments
- remove workarounds for fixed bugs
- replace error numbers with error names
- exclude subtests from execution which fail now because of
new limitations for partitioning functions
- remove code for the no more intended dual use
fast test in regression tests/slow test in testsuite
- analyze and fix problems with partition_char_innodb
- fix problems caused by last change of error numbers
- Introduce error name to error number mapping which makes
maintenance after next error renumbering easier
and auto_increment keys
Problems:
1. ALTER TABLE ... ORDER BY... doesn't make sence if there's a
user-defined clustered index in the table.
2. using a secondary index is slower than using a clustered one
for a table scan.
Fixes:
1. raise a warning.
2. use the clustered index.
In BUG#30244 added FOUND_ROWS() as an unsafe function, but that
works only in mixed mode under 5.1. There is a workaround that
can be used in statement-based mode either under 5.0 or 5.1
where the result of FOUND_ROWS() is stored into a user vari-
able and used that way instead. This will replicate correctly
even under statement-based replication, since it will write
a User_var entry to the binary log. For some other cases, the
value has to be passed explicitly.
This patch adds tests to demonstrate that the workarounds docu-
mented for statement-based replication works as advertised, and
does more extensive tests for cases that does not work under sta-
tement-based replication actually work under mixed mode by switch-
ing to row-based replication.
