The problem was that although this transformation was permanent, items of the new subtree were created in execute-local memory. The patch adds means to check if it is the first execute of a prepared statement, and if this is the case, to allocate items in memory of the prepared statement. The implementation: - backports Item_arena from 5.0 - adds Item_arena::is_stmt_prepare(), Item_arena::is_first_stmt_execute(). - deletes THD::allocate_temporary_pool_for_ps_preparing(), THD::free_temporary_pool_for_ps_preparing(); they were redundant. and adds a few invariants: - thd->free_list never contains junk (= freed items) - thd->current_arena is never null. If there is no prepared statement, it points at the thd. The rest of the patch contains mainly mechanical changes and cleanups. mysql-test/r/ps.result: Test results updated (test case for Bug#4912) mysql-test/t/ps.test: A test case for Bug#4912 "mysqld crashs in case a statement is executed a second time" sql/item_cmpfunc.cc: current_statement -> current_arena sql/item_subselect.cc: Statement -> Item_arena, current_statement -> current_arena sql/item_subselect.h: Item_subselect does not need to save thd->current_statement. sql/item_sum.cc: Statement -> Item_arena sql/item_sum.h: Statement -> Item_arena sql/mysql_priv.h: Statement -> Item_arena sql/sql_base.cc: current_statement -> current_arena sql/sql_class.cc: - Item_arena - convenient set_n_backup_statement, restore_backup_statement (nice idea, Sanja) sql/sql_class.h: - Item_arena: backport from 5.0 - allocate_temporary_pool_for_ps_preparing, free_temporary_pool_for_ps_preparing removed. sql/sql_derived.cc: current_statement -> current_arena sql/sql_lex.cc: current_statement -> current_arena sql/sql_parse.cc: Deploy invariant that thd->free_list never contains junk items (backport from 5.0). sql/sql_prepare.cc: - backporting Item_arena - no need to allocate_temporary_pool_for_ps_preparing(). sql/sql_select.cc: Fix for bug#4912 "mysqld crashs in case a statement is executed a second time": if this is the first execute of a prepared statement, negation elimination is done in memory of the prepared statement. sql/sql_union.cc: Backporting Item_arena from 5.0.

A fix for Bug#5748 "Prepared statement with BETWEEN and bigint values crashes mysqld": implementation for a generic item tree modifications registry. Every item tree modification which should be rolled back for subsequent execution of a prepared statement or stored procedure should be saved in the registry.

A fix and test case for Bug#5987 "subselect in bool function crashes server (prepared statements)": the bug was that all boolean items always recovered its original arguments at statement cleanup stage. This collided with Item_subselect::select_transformer, which tries to permanently change the item tree to use a transformed subselect instead of original one. So we had this call sequence for prepare: mysql_stmt_prepare -> JOIN::prepare -> Item_subselect::fix_fields -> the item tree gets transformed -> Item_bool_rowready_func2::cleanup, item tree is recovered to original state, while it shouldn't have been; mysql_stmt_execute -> attempts to execute a broken tree -> crash. Now instead of bluntly recovering all arguments of bool functions in Item_bool_rowready_func2::cleanup, we recover only those which were changed, and do it in one place. There still would exist a possibility for a collision with subselect tranformation, if permanent and temporary changes were performed at the same stage. But fortunately subselect transformation is always done first, so it doesn't conflict with the optimization done by propogate_cond_constants. Now we have: mysql_stmt_prepare -> JOIN::prepare -> subselect transformation permanently changes the tree -> cleanup doesn't recover anything, because nothing was registered for recovery. mysql_stmt_execute -> JOIN::prepare (the tree is already transformed, so it doesn't change), JOIN::optimize -> propogate_cond_constants -> temporary changes the item tree with constants -> JOIN::execute -> cleanup -> the changes done by propogate_cond_constants are recovered, as they were registered for recovery. mysql-test/r/ps.result: Bug#5987: test results fixed. mysql-test/t/ps.test: A test for bug#5987 "subselect in bool function crashes server (prepared statements)" sql/item.cc: resolve_const_item is now responsible to register all changes of the item tree for recovery sql/item.h: resolve_const_item signagture changed sql/item_cmpfunc.h: Arguments of boolean functions are now recovered using the centralized registry of THD. sql/sql_class.cc: It's crucial to add new items to the beginning of the recovery list, so that the recovery is performed in LIFO mode: otherwise if we change one node of a tree twice, it will be recovered to some intermediate state. sql/sql_select.cc: change_cond_ref_to_const and propogate_cond_constants are now responsible to register all changes of the item tree for recovery. The recovery is done using the centralized THD registry of changed tree items.

The fix makes Item_func_rand prepared-statements aware plus it fixes the case when RAND is used in prepared statements and replication is on (as well as several similar issues). Until now we did not reset THD before every execution of a prepared statement, so if some execution had set thd->time_zone_used or thd->rand_used they would not be reset until next mysql_parse.

Bug#31177: Server variables can't be set to their current values Default values of variables were not subject to upper/lower bounds and step, while setting variables was. Bounds and step are also applied to defaults now; defaults are corrected quietly, values given by the user are corrected, and a correction-warning is thrown as needed. Lastly, very large values could wrap around, starting from 0 again. They are bounded at the maximum value for the respective data-type now if no lower maximum is specified in the variable's definition. client/mysql.cc: correct maxima in options array client/mysqltest.c: adjust minimum for "sleep" option so default value is no longer out of bounds. include/m_string.h: ullstr() - the unsigned brother of llstr() include/my_getopt.h: Flag if we bounded the value (that is, correct anything aside from making value a multiple of block-size) mysql-test/r/delayed.result: We throw a warning now when we adjust out of range parameters. mysql-test/r/index_merge.result: We throw a warning now when we adjust out of range parameters. mysql-test/r/innodb.result: We throw a warning now when we adjust out of range parameters. mysql-test/r/innodb_mysql.result: We throw a warning now when we adjust out of range parameters. mysql-test/r/key_cache.result: We throw a warning now when we adjust out of range parameters. mysql-test/r/packet.result: We throw a warning now when we adjust out of range parameters. mysql-test/r/ps.result: We throw a warning now when we adjust out of range parameters. mysql-test/r/subselect.result: We throw a warning now when we adjust out of range parameters. mysql-test/r/type_bit.result: We throw a warning now when we adjust out of range parameters. mysql-test/r/type_bit_innodb.result: We throw a warning now when we adjust out of range parameters. mysql-test/r/variables.result: correct results: bounds and step apply to variables' default values, too mysql-test/t/variables.test: correct results: bounds and step apply to variables' default values, too mysys/my_getopt.c: - apply bounds/step to default values of variables (based on work by serg) - print complaints about incorrect values for variables (truncation etc., by requestion of consulting) - if no lower maximum is specified in variable definition, bound unsigned values at their maximum to prevent wrap-around - some calls to error_reporter had a \n, some didn't. remove \n from calls, let reporter-function handle it, so the default reporter behaves like that in mysqld sql/mysql_priv.h: correct RANGE_ALLOC_BLOCK_SIZE (cleared with monty) sql/mysqld.cc: correct maxima to correct data-type. correct minima where higher than default. correct range-alloc-block-size. correct inno variables so GET_* corresponds to actual variable's type. sql/set_var.cc: When the new value for a variable is out of bounds, we'll send the client a warning (but not if the value was simply not a multiple of 'blocksize'). sys_var_thd_ulong had this, sys_var_long_ptr_global didn't; broken out and streamlined to avoid duplication of code. strings/llstr.c: ullstr() - the unsigned brother of llstr()

A fix and a test case for Bug#16365 "Prepared Statements: DoS with too many open statements". The patch adds a new global variable @@max_prepared_stmt_count. This variable limits the total number of prepared statements in the server. The default value of @@max_prepared_stmt_count is 16382. 16382 small statements (a select against 3 tables with GROUP, ORDER and LIMIT) consume 100MB of RAM. Once this limit has been reached, the server will refuse to prepare a new statement and return ER_UNKNOWN_ERROR (unfortunately, we can't add new errors to 4.1 without breaking 5.0). The limit is changeable after startup and can accept any value from 0 to 1 million. In case the new value of the limit is less than the current statement count, no new statements can be added, while the old still can be used. Additionally, the current count of prepared statements is now available through a global read-only variable @@prepared_stmt_count. mysql-test/r/ps.result: Test results fixed (a test case for Bug#16365) mysql-test/t/ps.test: A test case for Bug#16365 "Prepared Statements: DoS with too many open statements". Also fix statement leaks in other tests. sql/mysql_priv.h: Add declarations for new global variables. sql/mysqld.cc: Add definitions of max_prepared_stmt_count, prepared_stmt_count. sql/set_var.cc: Implement support for @@prepared_stmt_count and @@max_prepared_stmt_count. Currently these variables are queried without acquiring LOCK_prepared_stmt_count due to limitations of the set_var/sys_var class design. Updates are, however, protected with a lock. sql/set_var.h: New declarations to add support for @@max_prepared_stmt_count. Implement a new class, where the lock to be used when updating a variable is a parameter. sql/sql_class.cc: Add accounting of the total number of prepared statements in the server to the methods of Statement_map. sql/sql_class.h: Add accounting of the total number of prepared statements in the server to the methods of Statement_map. sql/sql_prepare.cc: Statement_map::insert will now send a message in case of an error.

A fix and test cases for Bug#4968 "Stored procedure crash if cursor opened on altered table" Bug#19733 "Repeated alter, or repeated create/drop, fails" Bug#19182 "CREATE TABLE bar (m INT) SELECT n FROM foo; doesn't work from stored procedure." Bug#6895 "Prepared Statements: ALTER TABLE DROP COLUMN does nothing" Bug#22060 "ALTER TABLE x AUTO_INCREMENT=y in SP crashes server" Test cases for bugs 4968, 19733, 6895 will be added in 5.0. Re-execution of CREATE DATABASE, CREATE TABLE and ALTER TABLE statements in stored routines or as prepared statements caused incorrect results (and crashes in versions prior to 5.0.25). In 5.1 the problem occured only for CREATE DATABASE, CREATE TABLE SELECT and CREATE TABLE with INDEX/DATA DIRECTOY options). The problem of bugs 4968, 19733, 19282 and 6895 was that functions mysql_prepare_table, mysql_create_table and mysql_alter_table were not re-execution friendly: during their operation they used to modify contents of LEX (members create_info, alter_info, key_list, create_list), thus making the LEX unusable for the next execution. In particular, these functions removed processed columns and keys from create_list, key_list and drop_list. Search the code in sql_table.cc for drop_it.remove() and similar patterns to find evidence. The fix is to supply to these functions a usable copy of each of the above structures at every re-execution of an SQL statement. To simplify memory management, LEX::key_list and LEX::create_list were added to LEX::alter_info, a fresh copy of which is created for every execution. The problem of crashing bug 22060 stemmed from the fact that the above metnioned functions were not only modifying HA_CREATE_INFO structure in LEX, but also were changing it to point to areas in volatile memory of the execution memory root. The patch solves this problem by creating and using an on-stack copy of HA_CREATE_INFO (note that code in 5.1 already creates and uses a copy of this structure in mysql_create_table()/alter_table(), but this approach didn't work well for CREATE TABLE SELECT statement). mysql-test/r/ps.result: Update test results (Bug#19182, Bug#22060) mysql-test/t/ps.test: Add a test case for Bug#19182, Bug#22060 (4.1-only parts) sql/mysql_priv.h: LEX::key_list and LEX::create_list were moved to LEX::alter_info. Update declarations to use LEX::alter_info instead of these two members. sql/sql_class.h: Replace pair<columns, keys> with an instance of Alter_info in select_create constructor. We create a new copy of Alter_info each time we re-execute SELECT .. CREATE prepared statement. sql/sql_insert.cc: Adjust to a new signature of create_table_from_items. sql/sql_lex.cc: Implement Alter_info::Alter_info that would make a "deep" copy of all definition lists (keys, columns). sql/sql_lex.h: Move key_list and create_list to class Alter_info. Implement Alter_info::Alter_info that can be used with PS and SP. sql/sql_list.h: Implement a copy constructor of class List that makes a deep copy of all list nodes. sql/sql_parse.cc: Adjust to new signatures of mysql_create_table, mysql_alter_table, select_create. Functions mysql_create_index and mysql_drop_index has become identical after initialization of alter_info was moved to the parser, and were merged. Flag enable_slow_log was not updated for SQLCOM_DROP_INDEX, which is a bug. Just like CREATE INDEX, DROP INDEX is currently done via complete table rebuild and is rightfully a slow administrative statement. sql/sql_show.cc: Adjust mysqld_show_create_db to a new signature. sql/sql_table.cc: Adjust mysql_alter_table, mysql_recreate_table, mysql_create_table, mysql_prepare_table to new signatures. sql/sql_yacc.yy: LEX::key_list and LEX::create_list moved to class Alter_info

A fix and a test case for Bug#19022 "Memory bug when switching db during trigger execution" Bug#17199 "Problem when view calls function from another database." Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements" Documentation note: this patch introduces a change in behaviour of prepared statements. This patch adds a few new invariants with regard to how THD::db should be used. These invariants should be preserved in future: - one should never refer to THD::db by pointer and always make a deep copy (strmake, strdup) - one should never compare two databases by pointer, but use strncmp or my_strncasecmp - TABLE_LIST object table->db should be always initialized in the parser or by creator of the object. For prepared statements it means that if the current database is changed after a statement is prepared, the database that was current at prepare remains active. This also means that you can not prepare a statement that implicitly refers to the current database if the latter is not set. This is not documented, and therefore needs documentation. This is NOT a change in behavior for almost all SQL statements except: - ALTER TABLE t1 RENAME t2 - OPTIMIZE TABLE t1 - ANALYZE TABLE t1 - TRUNCATE TABLE t1 -- until this patch t1 or t2 could be evaluated at the first execution of prepared statement. CURRENT_DATABASE() still works OK and is evaluated at every execution of prepared statement. Note, that in stored routines this is not an issue as the default database is the database of the stored procedure and "use" statement is prohibited in stored routines. This patch makes obsolete the use of check_db_used (it was never used in the old code too) and all other places that check for table->db and assign it from THD::db if it's NULL, except the parser. How this patch was created: THD::{db,db_length} were replaced with a LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were manually checked and: - if the place uses thd->db by pointer, it was fixed to make a deep copy - if a place compared two db pointers, it was fixed to compare them by value (via strcmp/my_strcasecmp, whatever was approproate) Then this intermediate patch was used to write a smaller patch that does the same thing but without a rename. TODO in 5.1: - remove check_db_used - deploy THD::set_db in mysql_change_db See also comments to individual files. mysql-test/r/create.result: Modify the result file: a database can never be NULL. mysql-test/r/ps.result: Update test results (Bug#17199 et al) mysql-test/r/sp.result: Update test results (Bug#17199 et al) mysql-test/t/create.test: Update the id of the returned error. mysql-test/t/ps.test: Add test coverage for prepared statements and current database. In scope of work on Bug#17199 "Problem when view calls function from another database." mysql-test/t/sp.test: Add a test case for Bug#17199 "Problem when view calls function from another database." and Bug#18444 "Fully qualified stored function names don't work correctly in SELECT statements". Test a complementary problem. sql/item_strfunc.cc: Touch the code that reads thd->db (cleanup). sql/log_event.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/slave.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/slave.h: Remove a declaration for a method that is used only in one module. sql/sp.cc: Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand this function and ensure that it has no bugs. sql/sp.h: Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment. sql/sp_head.cc: - drop sp_name_current_db_new - a creator of sp_name class that was used when sp_name was created for an identifier without an explicitly initialized database. Now we pass thd->db to constructor of sp_name right in the parser. - rewrite sp_head::init_strings: name->m_db is always set now - use the new variant of sp_use_new_db - we don't need to update thd->db with SP MEM_ROOT pointer anymore when parsing a stored procedure, as noone will refer to it (yes!) sql/sp_head.h: - remove unneded methods and members sql/sql_class.h: - introduce 3 THD methods to work with THD::db: .set_db to assign the current database .reset_db to reset the current database (temporarily) or set it to NULL .opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL sql/sql_db.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/sql_insert.cc: - replace checks with asserts: table_list->db must be always set in the parser. sql/sql_lex.h: - add a comment sql/sql_parse.cc: - implement the invariant described in the changeset comment. - remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE: now db_load_routine uses its own LEX object and doesn't damage the main LEX. - add DBUG_ASSERT(0) to unused "check_db_used" sql/sql_table.cc: - replace a check with an assert (table_ident->db) sql/sql_trigger.cc: While we are at it, replace direct access to thd->db with a method. Should simplify future conversion of THD::db to LEX_STRING. sql/sql_udf.cc: - use thd->set_db instead of direct modification of to thd->db sql/sql_view.cc: - replace a check with an assert (view->db) sql/sql_yacc.yy: - make sure that we always copy table->db or name->db or ident->db or select_lex->db from thd->db if the former is not set. If thd->db is not set but is accessed, return an error. sql/tztime.cc: - be nice, never copy thd->db by pointer.

BUG#21856: Prepared Statements: crash if bad create When statement to be prepared contained CREATE PROCEDURE, CREATE FUNCTION or CREATE TRIGGER statements with a syntax error in it, the preparation would fail with syntax error message, but the memory could be corrupted. The problem occurred because we switch memroot when parse stored routine or trigger definitions, and on parse error we restored the original memroot only after performing some memory operations. In more detail: - prepared statement would activate its own memory root to parse the definition of the stored procedure. - SP would reset this memory root with its own memory root to parse SP statements - a syntax error would happen - prepared statement would restore the original memory root - stored procedure would restore what it thinks was the original memory root, but actually was the statement memory root. That led to double free - in destruction of the statement and in a next call to mysql_parse(). The solution is to restore memroot right after the failed parsing. mysql-test/r/ps.result: Add result for bug#21856: Prepared Statements: crash if bad create. mysql-test/t/ps.test: Add test case for bug#21856: Prepared Statements: crash if bad create. sql/sql_parse.cc: On parse error if thd->lex->sphead is set we have to free sp_head object to restore statement memroot, if it was switched during parsing. The change here is for safety, currently query_cache_abort() and lex->unit.cleanup() calls do not use current memroot. sql/sql_prepare.cc: On parse error if thd->lex->sphead is set we have to free sp_head object to restore statement memroot, if it was switched during parsing.

Proposed fix for bug#24491 "using alias from source table in insert ... on duplicate key". INSERT ... SELECT ... ON DUPLICATE KEY UPDATE which was used in stored routine or as prepared statement and which in its ON DUPLICATE KEY clause erroneously tried to assign value to a column mentioned only in its SELECT part was properly emitting error on the first execution but succeeded on the second and following executions. Code which is responsible for name resolution of fields mentioned in UPDATE clause (e.g. see select_insert::prepare()) modifies table list and Name_resolution_context used in this process. It uses Name_resolution_context_state::save_state/restore_state() to revert these modifications. Unfortunately those two methods failed to revert properly modifications to TABLE_LIST::next_name_resolution_table and this broke name resolution process for successive executions. This patch fixes Name_resolution_context_state::save_state/restore_state() in such way that it properly handles TABLE_LIST::next_name_resolution_table. mysql-test/r/ps.result: Added test case for bug#24491 "using alias from source table in insert ... on duplicate key" mysql-test/r/sp-error.result: Added test case for bug#24491 "using alias from source table in insert ... on duplicate key" mysql-test/t/ps.test: Added test case for bug#24491 "using alias from source table in insert ... on duplicate key" mysql-test/t/sp-error.test: Added test case for bug#24491 "using alias from source table in insert ... on duplicate key" sql/item.h: Name_resolution_context::save_state/restore_state(): At the moment these methods are used only by code implementing INSERT and INSERT ... SELECT statements. This code doesn't modify 'next_name_resolution_table' member of table list element corresponding to the first table of SELECT clause (pointed by 'first_name_resolution_table'). But it modifies table list element corresponding to the target table of INSERT (pointed by 'table_list') So these methods were changed to reflect this.
