unknown	b1b1d62776	Bug#30081: "ON UPDATE CURRENT_TIMESTAMP" wasn't shown by the SHOW FIELDS command and reported to a client. The fact that a timestamp field will be set to NO on UPDATE wasn't shown by the SHOW COMMAND and reported to a client through connectors. This led to problems in the ODBC connector and might lead to a user confusion. A new filed flag called ON_UPDATE_NOW_FLAG is added. Constructors of the Field_timestamp set it when a field should be set to NOW on UPDATE. The get_schema_column_record function now reports whether a timestamp field will be set to NOW on UPDATE. mysql-test/t/information_schema.test: A test case adjusted after fixing the bug#30081. mysql-test/r/type_timestamp.result: Adjusted a test case after fixing bug#30081. mysql-test/r/type_ranges.result: Adjusted a test case after fixing bug#30081. mysql-test/r/show_check.result: Adjusted a test case after fixing bug#30081. mysql-test/r/ps_5merge.result: Adjusted a test case after fixing bug#30081. mysql-test/r/ps_4heap.result: Adjusted a test case after fixing bug#30081. mysql-test/r/ps_3innodb.result: Adjusted a test case after fixing bug#30081. mysql-test/r/ps_2myisam.result: Adjusted a test case after fixing bug#30081. mysql-test/r/metadata.result: Adjusted a test case after fixing bug#30081. mysql-test/r/log_tables.result: Adjusted a test case after fixing bug#30081. mysql-test/r/information_schema.result: A test case adjusted after fixing the bug#30081. mysql-test/r/grant.result: Adjusted a test case after fixing bug#30081. tests/mysql_client_test.c: A test case adjusted after fixing the bug#30081. sql/sql_show.cc: Bug#30081: "ON UPDATE CURRENT_TIMESTAMP" wasn't shown by the SHOW FIELDS command and reported to a client.

unknown	e7c6a81f25	Fixed bug #28076 : inconsistent binary/varbinary comparison. After adding an index the <VARBINARY> IN (SELECT <BINARY> ...) clause returned a wrong result: the VARBINARY value was illegally padded with zero bytes to the length of the BINARY column for the index search. (<VARBINARY>, ...) IN (SELECT <BINARY>, ... ) clauses are affected too. sql/item.cc: Fixed bug #28076. The Item_cache_str::save_in_field method has been overloaded to check cached values for an illegal padding before the saving into a field. sql/item.h: Fixed bug #28076. The Item_cache_str::is_varbinary flag has been added and the Item_cache_str::save_in_field method has been overloaded to prevent cached values from an illegal padding when saving in fields. The signature of the Item_cache::get_cache method has been changed to accept pointers to Item instead of Item_result values. sql/item_cmpfunc.cc: Fixed bug #28076. The Item_in_optimizer::fix_left method has been modified to to call Item_cache::get_cache in a new manner. sql/item_subselect.cc: Fixed bug #28076.

unknown	a41b476314	Bug#31700: thd->examined_row_count not incremented for 'const' type queries UNIQUE (eq-ref) lookups result in table being considered as a "constant" table. Queries that consist of only constant tables are processed in do_select() in a special way that doesn't invoke evaluate_join_record(), and therefore doesn't increase the counters join->examined_rows and join->thd->row_count. The patch increases these counters in this special case. NOTICE: This behavior seems to contradict what the documentation says in Sect. 5.11.4: "Queries handled by the query cache are not added to the slow query log, nor are queries that would not benefit from the presence of an index because the table has zero rows or one row." No test case in 5.0 as issue shows only in slow query log, and other counters can give subtly different values (with regard to counting in create_sort_index(), synthetic rows in ROLLUP, etc.). sql/sql_class.h: add documentation for some variables sql/sql_select.cc: Don't forget const tables when counting read records!	18 years ago
unknown	ac3ef6c759	Bug#31800: Date comparison fails with timezone and slashes for greater than comparison BETWEEN was more lenient with regard to what it accepted as a DATE/DATETIME in comparisons than greater-than and less-than were. ChangeSet makes < > comparisons similarly robust with regard to trailing garbage (" GMT-1") and "missing" leading zeros. Now all three comparators behave similarly in that they throw a warning for "junk" at the end of the data, but then proceed anyway if possible. Before < > fell back on a string- (rather than date-) comparison when a warning-condition was raised in the string-to-date conversion. Now the fallback only happens on actual errors, while warning- conditions still result in a warning being to delivered to the client. mysql-test/r/select.result: Show that we compare DATE/DATETIME-like strings as date(time)s now, rather than as bin-strings. Adjust older result as "2005-09-3a" is now correctly seen as "2005-09-3" + trailing garbage, rather than as "2005-09-30". mysql-test/t/select.test: Show that we compare DATE/DATETIME-like strings as date(time)s now, rather than as bin-strings. sql-common/my_time.c: correct/clarify date-related comments, particulary for check_date(). doxygenize comment while at it. sql/item_cmpfunc.cc: get_date_from_str() no longer signals an error when all we had was a warning-condition -- and one we already gave the user a warning for at that.

unknown	55499d2bf4	Fix for bug #32202 : ORDER BY not working with GROUP BY The bug is a regression introduced by the fix for bug30596. The problem was that in cases when groups in GROUP BY correspond to only one row, and there is ORDER BY, the GROUP BY was removed and the ORDER BY rewritten to ORDER BY <group_by_columns> without checking if the columns in GROUP BY and ORDER BY are compatible. This led to incorrect ordering of the result set as it was sorted using the GROUP BY columns. Additionaly, the code discarded ASC/DESC modifiers from ORDER BY even if its columns were compatible with the GROUP BY ones. This patch fixes the regression by checking if ORDER BY columns form a prefix of the GROUP BY ones, and rewriting ORDER BY only in that case, preserving the ASC/DESC modifiers. That check is sufficient, since the GROUP BY columns contain a unique index. mysql-test/r/group_by.result: Added a test case for bug #32202. mysql-test/t/group_by.test: Added a test case for bug #32202. sql/sql_select.cc: In cases when groups in GROUP BY correspond to only one row and there is ORDER BY, rewrite the query to ORDER BY <group_by_columns> only if the columns in ORDER BY and GROUP BY are compatible, i.e. either one forms a prefix for another.	18 years ago
unknown	737cdfeaeb	Fix for bug #32020 : loading udfs while --skip-grant-tables is enabled causes out of memory errors The code in mysql_create_function() and mysql_drop_function() assumed that the only reason for UDFs being uninitialized at that point is an out-of-memory error during initialization. However, another possible reason for that is the --skip-grant-tables option in which case UDF initialization is skipped and UDFs are unavailable. The solution is to check whether mysqld is running with --skip-grant-tables and issue a proper error in such a case. mysql-test/r/skip_grants.result: Added a test case for bug #32020. mysql-test/t/skip_grants.test: Added a test case for bug #32020. sql/sql_udf.cc: Issue a proper error when a user tries to CREATE/DROP a UDF on a server running with the --skip-grant-tables option.	18 years ago
unknown	b1fc4b9e63	Bug#31990: MINUTE() and SECOND() return bogus results when used on a DATE HOUR(), MINUTE(), ... returned spurious results when used on a DATE-cast. This happened because DATE-cast object did not overload get_time() method in superclass Item. The default method was inappropriate here and misinterpreted the data. Patch adds missing method; get_time() on DATE-casts now returns SQL-NULL on NULL input, 0 otherwise. This coincides with the way DATE-columns behave. mysql-test/r/cast.result: Show that HOUR(), MINUTE(), ... return sensible values when used on DATE-cast objects, namely NULL for NULL-dates and 0 otherwise. Show that this coincides with how DATE-columns behave. mysql-test/t/cast.test: Show that HOUR(), MINUTE(), ... return sensible values when used on DATE-cast objects, namely NULL for NULL-dates and 0 otherwise.

unknown	0a7a55d175	Fix for bug #32103 : optimizer crash when join on int and mediumint with variable in where clause. Problem: the new_item() method of Item_uint used an incorrect constructor. "new Item_uint(name, max_length)" calls Item_uint::Item_uint(const char str_arg, uint length) which assumes the first argument to be the string representation of the value, not the item's name. This could result in either a server crash or incorrect results depending on usage scenarios. Fixed by using the correct constructor in new_item(): Item_uint::Item_uint(const char str_arg, longlong i, uint length). mysql-test/r/select.result: Added a test case for bug #32103. mysql-test/t/select.test: Added a test case for bug #32103. sql/item.h: Use the correct constructor for Item_uint in Item_uint::new_item().	18 years ago

Fixed by checking the thread's 'killed' status in check_quick_keys() and interrupting the calculation process if it is set to a non-zero value. sql/opt_range.cc: Check the thread's 'killed' status in check_quick_keys() and interrupt the calculation process if it is set to a non-zero value.	18 years ago
unknown	f668665955	Fix for bug #30666 : Incorrect order when using range conditions on 2 tables or more The problem was that the optimizer used the join buffer in cases when the result set is ordered by filesort. This resulted in the ORDER BY clause being ignored, and the records being returned in the order determined by the order of matching records in the last table in join. Fixed by relaxing the condition in make_join_readinfo() to take filesort-ordered result sets into account, not only index-ordered ones. mysql-test/r/select.result: Added a test case for bug #30666. mysql-test/t/select.test: Added a test case for bug #30666. sql/sql_select.cc: Relaxed the condition to determine when the join buffer usage must be disabled. The condition is now true for cases when the result set is ordered by filesort, that is when 'join->order && !join->skip_sort_order' is true.	18 years ago

unknown	9e6bb07d38	Bug#30889: filesort and order by with float/numeric crashes server There are two problems with ROUND(X, D) on an exact numeric (DECIMAL, NUMERIC type) field of a table: 1) The implementation of the ROUND function would change the number of decimal places regardless of the value decided upon in fix_length_and_dec. When the number of decimal places is not constant, this would cause an inconsistent state where the number of digits was less than the number of decimal places, which crashes filesort. Fixed by not allowing the ROUND operation to add any more decimal places than was decided in fix_length_and_dec. 2) fix_length_and_dec would allow the number of decimals to be greater than the maximium configured value for constant values of D. This led to the same crash as in (1). Fixed by not allowing the above in fix_length_and_dec. mysql-test/r/type_decimal.result: Bug#30889: Test result mysql-test/t/type_decimal.test: Bug#30889: Test case sql/item_func.cc: Bug#30889: - Avoid setting number of digits after decimal point (scale) higher than its maximum value. - Avoid increasing the number of decimal places in ::decimal_op sql/item_func.h: Bug#30889: Added comments to the declarations of Item_func_numhybrid::<type>_op family of methods.	18 years ago

unknown	974201c7e0	Fix for bug #29131 : SHOW VARIABLES reports variable 'log' but SET doesn't recognize it This is a 5.1 version of the patch. Problem: 'log' and 'log_slow_queries' were "fixed" variables, i.e. they showed up in SHOW VARIABLES, but could not be used in expressions like "select @@log". Also, using them in the SET statement produced an incorrect "unknown system variable" error. Solution: Since as of MySQL 5.1.12 one can enable or disable the general query log or the slow query log at runtime by changing values of general_log/slow_query_log, make 'log' and 'log_slow_queries" to be synonyms for 'general_log' and 'slow_query_log' respectively. This makes expressions using the '@@var' syntax backward compatible with 5.0 and SHOW VARIABLES output to be consistent with the SET statement. mysql-test/r/log_state.result: Added a test case for bug #29131. mysql-test/t/log_state.test: Added a test case for bug #29131. sql/set_var.cc: Made the 'log' and 'log_slow_queries' system variables to be synonyms for 'general_log' and 'slow_query_log'.	18 years ago

unknown	b9b481ec70	Bug#21557 entries in the general query log truncated at 1000 characters. The general log write function (general_log_print) uses printf style arguments which need to be pre-processed, meaning that the all arguments are copied to a single buffer and the problem is that the buffer size is constant (1022 characters) but queries can be much larger then this. The solution is to introduce a new log write function that accepts a buffer and it's length as arguments. The function is to be used when a formatted output is not required, which is the case for almost all query write-to-log calls. This is a incompatible change with respect to the log format of prepared statements. mysql-test/r/log_tables.result: Add test case result for Bug#21557 mysql-test/t/log_tables.test: Add test case for Bug#21557 sql/log.cc: Introduce the logger function general_log_write which is similar to general_log_print but accepts a single buffer and the buffer length. The function doesn't perform any formatting and sends the buffer directly to the underlying log handlers. sql/log.h: Introduce the logger function general_log_write. sql/log_event.cc: Pass the query buffer directly to the logger function, formatting is not required on this case. sql/mysql_priv.h: Prototype for the logger function general_log_write. sql/sp_head.cc: Pass the query buffer directly to the logger function, formatting is not required on this case. sql/sql_parse.cc: Pass the buffer directly to the logger function when formatting is not required. sql/sql_prepare.cc: Don't log the statement id, it avoids making a extra copy of the query and the query is not truncated anymore if it exceeds the limit.	18 years ago
unknown	bf82c2f9b4	Bug#31692 - binlog_killed.test crashes sometimes The server crashed when a thread was killed while locking the general_log table at statement begin. The general_log table is handled like a performance schema table. The state of open tables is saved and cleared so that this table seems to be the only open one. Then this table is opened and locked. After writing, the table is closed and the open table state is restored. Before restoring, however, it is asserted that there is no current table open. After locking the table, mysql_lock_tables() checks if the thread was killed in between. If so, it unlocks the table and returns an error. open_ltable() just returns with the error and leaves closing of the table to close_thread_tables(), which is called at statement end. open_performance_schema_table() did not take this into account. It assumed that a failed open_ltable() would not leave an open table behind. Fixed by closing thread tables after open_ltable() and before restore_backup_open_tables_state() if the thread was killed. No test case. It requires correctly timed parallel execution. Since this bug was detected by the test suite, it seems dispensable to add another test. sql/sql_base.cc: Bug#31692 - binlog_killed.test crashes sometimes Closing thread tables after open_ltable() and before restore_backup_open_tables_state() if the thread was killed.	18 years ago

unknown	f1d7a96b0a	Bug#28318 (CREATE FUNCTION (UDF) requires a schema) -- part II The root cause of the issue was that the CREATE FUNCTION grammar, for User Defined Functions, was using the sp_name rule. The sp_name rule is intended for fully qualified stored procedure names, like either ident.ident, or just ident but with a default database implicitly selected. A UDF does not have a fully qualified name, only a name (ident), and should not use the sp_name grammar fragment during parsing. The fix is to re-organize the CREATE FUNCTION grammar, to better separate: - creating UDF (no definer, can have AGGREGATE, simple ident) - creating Stored Functions (definer, no AGGREGATE, fully qualified name) With the test case provided, another issue was exposed which is also fixed: the DROP FUNCTION statement was using sp_name and also failing when no database is implicitly selected, when droping UDF functions. The fix is also to change the grammar so that DROP FUNCTION works with both the ident.ident syntax (to drop a stored function), or just the ident syntax (to drop either a UDF or a Stored Function, in the current database) mysql-test/r/sp-error.result: Adjust test results mysql-test/r/udf.result: Adjust test results mysql-test/t/sp-error.test: Adjust test results mysql-test/t/udf.test: Adjust test results sql/sql_parse.cc: CREATE UDF FUNCTION does not use a fully qualified name. sql/sql_yacc.yy: Fix grammar for CREATE / DROP FUNCTION, FOR udf Improve error messages for select no_such_function()	18 years ago
