incomplete in 5.0 (and review fixes). When in 5.0.13 I introduced class Prepared_statement and methods ::prepare and ::execute, general logging was left out of this class. This was good for stored procedures, since in stored procedures we do not log sub-statements, but introduced a regression in case of SQL syntax for prepared statements, as previously we would log the actual statements to the log, and after the change we would log only COM_QUERY text. Restore the old behavior, but still suppress logging if inside a stored procedure. Based on a community contributed patch from Vladimir Shebordaev. No test case since we do not have a mechanism to test output of the general log. sql/sql_prepare.cc: Apply community contributed fix for Bug#13326 SQLPS statement logging is incomplete in 5.0 (and review fixes).

causes full table lock on innodb table. Also fixes Bug#28502 Triggers that update another innodb table will block on X lock unnecessarily (duplciate). Code review fixes. Both bugs' synopses are misleading: InnoDB table is not X locked. The statements, however, cannot proceed concurrently, but this happens due to lock conflicts for tables used in triggers, not for the InnoDB table. If a user had an InnoDB table, and two triggers, AFTER UPDATE and AFTER INSERT, competing for different resources (e.g. two distinct MyISAM tables), then these two triggers would not be able to execute concurrently. Moreover, INSERTS/UPDATES of the InnoDB table would not be able to run concurrently. The problem had other side-effects (see respective bug reports). This behavior was a consequence of a shortcoming of the pre-locking algorithm, which would not distinguish between different DML operations (e.g. INSERT and DELETE) and pre-lock all the tables that are used by any trigger defined on the subject table. The idea of the fix is to extend the pre-locking algorithm to keep track, for each table, what DML operation it is used for and not load triggers that are known to never be fired. mysql-test/r/trigger-trans.result: Update results (Bug#26141) mysql-test/r/trigger.result: Update results (Bug#28502) mysql-test/t/trigger-trans.test: Add a test case for Bug#26141 mixing table types in trigger causes full table lock on innodb table. mysql-test/t/trigger.test: Add a test case for Bug#28502 Triggers that update another innodb table will block echo on X lock unnecessarily. Add more test coverage for triggers. sql/item.h: enum trg_event_type is needed in table.h sql/sp.cc: Take into account table_list->trg_event_map when determining what tables to pre-lock. After this change, if we attempt to fire a trigger for which we had not pre-locked any tables, error 'Table was not locked with LOCK TABLES' will be printed. This, however, should never happen, provided the pre-locking algorithm has no programming bugs. Previously a trigger key in the sroutines hash was based on the name of the table the trigger belongs to. This was possible because we would always add to the pre-locking list all the triggers defined for a table when handling this table. Now the key is based on the name of the trigger, owing to the fact that a trigger name must be unique in the database it belongs to. sql/sp_head.cc: Generate sroutines hash key in init_spname(). This is a convenient place since there we have all the necessary information and can avoid an extra alloc. Maintain and merge trg_event_map when adding and merging elements of the pre-locking list. sql/sp_head.h: Add ,m_sroutines_key member, used when inserting the sphead for a trigger into the cache of routines used by a statement. Previously the key was based on the table name the trigger belonged to, since for a given table we would add to the sroutines list all the triggers defined on it. sql/sql_lex.cc: Introduce a new lex step: set_trg_event_type_for_tables(). It is called when we have finished parsing but before opening and locking tables. Now this step is used to evaluate for each TABLE_LIST instance which INSERT/UPDATE/DELETE operation, if any, it is used in. In future this method could be extended to aggregate other information that is hard to aggregate during parsing. sql/sql_lex.h: Add declaration for set_trg_event_type_for_tables(). sql/sql_parse.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). Remove tabs. sql/sql_prepare.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_trigger.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_trigger.h: Remove an obsolete member. sql/sql_view.cc: Call set_trg_event_type_for_tables() after MYSQLparse(). sql/sql_yacc.yy: Move assignment of sp_head::m_type before calling sp_head::init_spname(), one is now used inside another. sql/table.cc: Implement TABLE_LIST::set_trg_event_map() - a method that calculates wh triggers may be fired on this table when executing a statement. sql/table.h: Add missing declarations. Move declaration of trg_event_type from item.h (it will be needed for trg_event_map bitmap when we start using Bitmap template instead of uint8).

A race condition in the integration between MyISAM and the query cache code caused the query cache to fail to invalidate itself on concurrently inserted data. This patch fix this problem by using the existing handler interface which, upon each statement cache attempt, compare the size of the table as viewed from the cache writing thread and with any snap shot of the global table state. If the two sizes are different the global table size is unknown and the current statement can't be cached. mysql-test/r/query_cache.result: Added test case mysql-test/t/query_cache.test: Added test case sql/ha_myisam.cc: - Implemented handler interface for ha_myisam class to dermine if the table belonging to the currently processed statement can be cached or not. sql/ha_myisam.h: - Implemented handler interface for ha_myisam class to dermine if the table belonging to the currently processed statement can be cached or not. sql/handler.h: - Documented register_query_cache_table method in the handler interface.

The need arose when working on Bug 26141, where it became necessary to replace TABLE_LIST with its forward declaration in a few headers, and this involved a lot of s/TABLE_LIST/st_table_list/. Although other workarounds exist, this patch is in line with our general strategy of moving away from typedef-ed names. Sometime in future we might also rename TABLE_LIST to follow the coding style, but this is a huge change. sql/item.cc: st_table_list -> TABLE_LIST sql/item.h: st_table_list -> TABLE_LIST sql/mysql_priv.h: st_table_list -> TABLE_LIST sql/sql_base.cc: st_table_list -> TABLE_LIST sql/sql_lex.cc: st_table_list -> TABLE_LIST sql/sql_lex.h: st_table_list -> TABLE_LIST sql/sql_select.cc: st_table_list -> TABLE_LIST sql/sql_show.cc: st_table_list -> TABLE_LIST sql/sql_udf.h: Was not needed. sql/table.cc: st_table_list -> TABLE_LIST sql/table.h: st_table_list -> TABLE_LIST

fails if a database is not selected prior. The problem manifested itself when a user tried to create a routine that had non-fully-qualified identifiers in its bodies and there was no current database selected. This is a regression introduced by the fix for Bug 19022: The patch for Bug 19022 changes the code to always produce a warning if we can't resolve the current database in the parser. In this case this was not necessary, since even though the produced parsed tree was incorrect, we never re-use sphead that was obtained at first parsing of CREATE PROCEDURE. The sphead that is anyhow used is always obtained through db_load_routine, and there we change the current database to sphead->m_db before calling yyparse. The idea of the fix is to resolve the current database directly using lex->sphead->m_db member when parsing a stored routine body, when such is present. This patch removes the need to reset the current database when loading a trigger or routine definition into SP cache. The redundant code will be removed in 5.1. mysql-test/r/sp.result: Update test results (Bug#29050) mysql-test/r/trigger.result: Update results. mysql-test/t/sp.test: Add a test case for Bug#29050 mysql-test/t/trigger.test: Fix wrong behavior covered with tests. sql/sql_lex.cc: Implement st_lex::copy_db_to(). sql/sql_lex.h: Declare st_lex::copy_db_to(). sql/sql_parse.cc: Use st_lex::copy_db_to() in add_table_to_list, rather than THD::copy_db_to(). The former will use the database of the sphead, if we're parsing a stored routine, not the default database in THD. The default database is needed to initialize tables->db when the database part was not explicitly specified in the identifier. sql/sql_yacc.yy: Use st_lex::copy_db_to() in the parser, rather than THD::copy_db_to(). The former will use the database of the sphead, if we're parsing a stored routine, not the default database in THD.

'No database selected' is reported when calling stored procedures Remove the offending warning introduced by the fix for Bug 25082 This minimal patch relies on the intrinsic knowledge of the fact that mysql_change_db is never called with 'force_switch' set to TRUE when such a warning may be needed: * every stored routine belongs to a database (unlike, e.g., a user defined function, which does not), so if we're activating the database of a stored routine, it can never be NULL. Therefore, this branch is never called for activation. * if we're restoring the 'old' current database after routine execution is complete, we should not issue a warning, since it's OK to call a routine without having previously selected the current database. TODO: 'force_switch' is an ambiguous flag, since we do not actually have to 'force' the switch in case of stored routines at all. When we activate the routine's database, we should perform all the checks as in case of 'use db', and so we already do (in this case 'force_switch' is unused). When we load a routine into cache, we should not use mysql_change_db at all, since there it's enough to call thd->reset_db(). We do it this way for triggers, but code for routines is different (wrongly). TODO: bugs are lurking in replication, since it bypasses mysql_change_db and calls thd->[re_]set_db to set the current database. The latter does not change thd->db_charset, thd->sctx->db_access and thd->variables.collation_database (and this may have nasty side effects). These todo items are to be addressed in a separate patch, if at all. mysql-test/r/sp.result: Update results (Bug#28551) mysql-test/t/sp.test: Add a test case (Bug#28551) sql/sp.cc: Remove an obsolete comment. Replace a check with an assert. sql/sql_db.cc: Remove the offending warning introduced by the fix for Bug 25082 This minimal patch relies on the intrinsic knowledge of the fact that mysql_change_db is never called with 'force_switch' set to TRUE when such a warning may be needed.

When a UNION statement forced conversion of an UTF8 charset value to a binary charset value, the byte length of the result values was truncated to the CHAR_LENGTH of the original UTF8 value. sql/item.cc: Fixed bug #29205. The calculation of data length was modified in the Item_type_holder::join_types method to take into account possible conversion of a multibyte charset value to a binary charset value, when each multibyte character is converted into a sequence of bytes (not to a single byte of binary charset). mysql-test/t/ctype_utf8.test: Updated test case for bug #29205. mysql-test/r/ctype_utf8.result: Updated test case for bug #29205.

spaces. When the my_strnncollsp_simple function compares two strings and one is a prefix of another then this function compares characters in the rest of longer key with the space character to find whether the longer key is greater or less. But the sort order of the collation isn't used in this comparison. This may lead to a wrong comparison result, wrongly created index or wrong order of the result set of a query with the ORDER BY clause. Now the my_strnncollsp_simple function uses collation sort order to compare the characters in the rest of longer key with the space character. mysql-test/t/ctype_collate.test: Added a test case for the bug#29261: Sort order of the collation wasn't used when comparing trailing spaces. mysql-test/r/ctype_collate.result: Added a test case for the bug#29261: Sort order of the collation wasn't used when comparing trailing spaces. strings/ctype-simple.c: Bug#29261: Sort order of the collation wasn't used when comparing trailing spaces. Now the my_strnncollsp_simple function uses collation sort order to compare the characters in the rest of longer key with the space character.

query / no aggregate of subquery The optimizer counts the aggregate functions that appear as top level expressions (in all_fields) in the current subquery. Later it makes a list of these that it uses to actually execute the aggregates in end_send_group(). That count is used in several places as a flag whether there are aggregates functions. While collecting the above info it must not consider aggregates that are not aggregated in the current context. It must treat them as normal expressions instead. Not doing that leads to incorrect data about the query, e.g. running a query that actually has no aggregate functions as if it has some (and hence is expected to return only one row). Fixed by ignoring the aggregates that are not aggregated in the current context. One other smaller omission discovered and fixed in the process : the place of aggregation was not calculated for user defined functions. Fixed by calling Item_sum::init_sum_func_check() and Item_sum::check_sum_func() as it's done for the rest of the aggregate functions. mysql-test/r/subselect.result: Bug #27333: test case mysql-test/t/subselect.test: Bug #27333: test case sql/item_subselect.cc: Bug#27333: need select_lex to filter out aggregates that are not aggregated in the current select. sql/item_sum.cc: Bug#27333: need select_lex to filter out aggregates that are not aggregated in the current select. sql/item_sum.h: Bug#27333: calculate the place of aggregation for user defined functions. sql/sql_select.cc: Bug#27333: When counting the aggregated functions and collecting a list of them we must not consider the aggregates that are not aggregated in the local context as "local" : i.e. we must treat them as normal functions and not add them to the aggregate functions list. sql/sql_select.h: Bug#27333: need select_lex to filter out aggregates that are not aggregated in the current select.

SHOW CREATE TABLE or SELECT FROM I_S. Actually, the bug discovers two problems: - the original query is not preserved properly. This is the problem of BUG#16291; - the resultset of SHOW CREATE TABLE statement is binary. This patch fixes the second problem for the 5.0. Both problems will be fixed in 5.1. mysql-test/r/show_check.result: Update result file. mysql-test/t/show_check.test: Provide test case for BUG#10491. sql/item.h: Use utf8_general_ci instead of binary collation by default, because for views and base tables utf8 is the character set in which their definition is stored. For system constants it's the default character set, and for other objects (routines, triggers), no character set is stored, and therefore no character set is known, so returning utf8 is just as good as any non-binary character set. This latter problem is fixed in 5.1 by 16291. In 5.1 we will return the "real" character set.

Thanks to Martin Friebe for finding and submitting a fix for this bug! A table with maximum number of key segments and maximum length key name would have a corrupted .frm file, due to an incorrect calculation of the complete key length. Now the key length is computed correctly (I hope) :-) MyISAM would reject a table with the maximum number of keys and the maximum number of key segments in all keys. It would allow one less than this total maximum. Now MyISAM accepts a table defined with the maximum. (This is a very minor issue.) myisam/mi_open.c: Bug #26642: change >= to > in a comparison (i.e., error only if key_parts_in_table really is greater than MAX_KEY * MAX_KEY_SEG) mysql-test/r/create.result: Bug #26642: test case mysql-test/t/create.test: Bug #26642: test case sql/table.cc: Bug #26642: In create_frm(), fix formula for key_length; it was too small by (keys * 2) bytes

Sometimes special 0 ENUM values was ALTERed to normal empty string ENUM values. Special 0 ENUM value has the same string representation as normal ENUM value defined as '' (empty string). The do_field_string function was used to convert ENUM data at an ALTER TABLE request, but this function doesn't care about numerical "indices" of ENUM values, i.e. do_field_string doesn't distinguish a special 0 value from an empty string value. A new copy function called do_field_enum has been added to copy special 0 ENUM values without conversion to an empty string. sql/field_conv.cc: Fixed bug #29251. The Copy_field::get_copy_func method has been modified to return a pointer to the do_field_enum function if a conversion between two columns of incompatible enum types is required. The do_field_enum function has been added for the correct conversion of special 0 enum values. mysql-test/t/type_enum.test: Updated test case for bug #29251. mysql-test/r/type_enum.result: Updated test case for bug #29251.

a lookup into a BINARY index by a key ended with spaces. It caused an assertion abort for a debug version and wrong results for non-debug versions. The problem occurred because the function _mi_pack_key stripped off the trailing spaces from binary search keys while the function _mi_make_key did not do it when keys were inserted into the index. Now the function _mi_pack_key does not remove the trailing spaces from search keys if they are of the binary type. mysql-test/r/binary.result: Added a test case for bug #29087. mysql-test/t/binary.test: Added a test case for bug #29087.

If one sets MYSQL_READ_DEFAULTS_FILE and MYSQL_READ_DEFAULT_GROUP options after mysql_real_connect() called with that MYSQL instance, these options will affect next mysql_reconnect then. As we use a copy of the original MYSQL object inside mysql_reconnect, and mysql_real_connect frees options.my_cnf_file and _group strings, we will free these twice when we execute mysql_reconnect with the same MYSQL for the second time. I don't think we should ever read defaults files handling mysql_reconnect. So i just set them to 0 for the temporary MYSQL object there/ sql-common/client.c: Bug #29247 Double free in libmysqlclient_r when mysql restarted. we don't need mysql_real_connect to reread defaults file in this case, so set related parameters to zero

LOCK TABLES takes a list of tables to lock. It may lock several tables successfully and then encounter a tables that it can't lock, e.g. because it's locked. In such case it needs to undo the locks on the already locked tables. And it does that. But it has also notified the relevant table storage engine handlers that they should lock. The only reliable way to ensure that the table handlers will give up their locks is to end the transaction. This is what UNLOCK TABLE does : it ends the transaction if there were locked tables by LOCK tables. It is possible to end the transaction when the lock fails in LOCK TABLES because LOCK TABLES ends the transaction at its start already. Fixed by ending (again) the transaction when LOCK TABLES fails to lock a table. mysql-test/r/innodb_mysql.result: Bug #29154: test case mysql-test/t/innodb_mysql.test: Bug #29154: test case sql/sql_parse.cc: Bug #29154: end the trasaction at a failing LOCK TABLES so the handler can free its locks.
