gkodinov/kgeorge@magare.gmz	8c3d5135ba	Bug #30355 : Incorrect ordering of UDF results There's currently no way of knowing the determinicity of an UDF. And the optimizer and the sequence() UDFs were making wrong assumptions about what the is_const member means. Plus there was no implementation of update_system_tables() causing the optimizer to overwrite the information returned by the <udf>_init function. Fixed by equating the assumptions about the semantics of is_const and providing a implementation of update_used_tables(). Added a TODO item for the UDF API change needed to make a better implementation.	18 years ago

gkodinov/kgeorge@magare.gmz	2e2ac428ae	Bug #30788 : Inconsistent retrieval of char/varchar Index lookup does not always guarantee that we can simply remove the relevant conditions from the WHERE clause. Reasons can be e.g. conversion errors, partial indexes etc. The optimizer was removing these parts of the WHERE condition without any further checking. This leads to "false positives" when using indexes. Fixed by checking the index reference conditions (using WHERE) when using indexes with sub-queries.	18 years ago

evgen@moonbone.local	da7470afb1	Bug#30384: Having SQL_BUFFER_RESULT option in the CREATE .. KEY(..) .. SELECT led to creating corrupted index. Corrected fix. The new method called prepare2 is added to the select_create class. As all preparations are done by the select_create::prepare function it doesn't do anything. Slightly changed algorithm of calling the start_bulk_insert function. Now it's called from the select_insert::prepare2 function when the SQL_BUFFER_RESULT flags is set. The is_bulk_insert_mode flag is removed as it is not needed anymore.	18 years ago
evgen@moonbone.local	67cae0d48d	Bug#31048: Many nested subqueries may cause server crash. This bug is actually two. The first one manifests itself on an EXPLAIN SELECT query with nested subqueries that employs the filesort algorithm. The whole SELECT under explain is marked as UNCACHEABLE_EXPLAIN to preserve some temporary structures for explain. As a side-effect of this values of nested subqueries weren't cached and subqueries were re-evaluated many times. Each time buffer for filesort was allocated but wasn't freed because freeing occurs at the end of topmost SELECT. Thus all available memory was eaten up step by step and OOM event occur. The second bug manifests itself on SELECT queries with conditions where a subquery result is compared with a key field and the subquery itself also has such condition. When a long chain of such nested subqueries is present the stack overrun occur. This happens because at some point the range optimizer temporary puts the PARAM structure on the stack. Its size if about 8K and the stack is exhausted very fast. Now the subselect_single_select_engine::exec function allows subquery result caching when the UNCACHEABLE_EXPLAIN flag is set. Now the SQL_SELECT::test_quick_select function calls the check_stack_overrun function for stack checking purposes to prevent server crash.	18 years ago

kaa@polly.(none)	82c4059fc9	Fix for bug #32221 : bug25714, mytest, mysql_client_test complaints and crashes. MySQL distributions contain a number of programs that are used only by the MySQL test suite internally, i.e. they are not indended to be invoked directly by a user. As a result, such programs are not documented, do not have any built-in help or proper error reporting, which may confuse users. This patch fixes the problem with the following changes: - mytest, libmysqltest and all references to them were removed from the distribution since they are not used anymore - bug25714 now displays an error message when run with incorrect arguments or with the --help option - mysql_client_test now does not call abort() in case of errors, instead it does a clean exit() with a proper error status.	18 years ago

gkodinov/kgeorge@magare.gmz	3384d3e96c	Bug #31562 : HAVING and lower case The columns in HAVING can reference the GROUP BY and SELECT columns. There can be "table" prefixes when referencing these columns. And these "table" prefixes in HAVING use the table alias if available. This means that table aliases are subject to the same storage rules as table names and are dependent on lower_case_table_names in the same way as the table names are. Fixed by : 1. Treating table aliases as table names and make them lowercase when printing out the SQL statement for view persistence. 2. Using case insensitive comparison for table aliases when requested by lower_case_table_names	18 years ago
