Nirbhay Choubey	7305be2f7e	MDEV-5535: Cannot reopen temporary table mysqld maintains a list of TABLE objects for all temporary tables created within a session in THD. Here each table is represented by a TABLE object. A query referencing a particular temporary table for more than once, however, failed with ER_CANT_REOPEN_TABLE error because a TABLE_SHARE was allocate together with the TABLE, so temporary tables always had only one TABLE per TABLE_SHARE. This patch lift this restriction by separating TABLE and TABLE_SHARE objects and storing TABLE_SHAREs for temporary tables in a list in THD, and TABLEs in a list within their respective TABLE_SHAREs.	10 years ago
Monty	3bca8db4f9	MDEV-6152: Remove calls to current_thd while creating Item - Part 4: Removing calls to sql_alloc() and sql_calloc() Other things: - Added current_thd in some places to make it clear that it's called (easier to remove later) - Move memory allocation from Item_func_case::fix_length_and_dec() to Item_func_case::fix_fields() - Added mem_root to some new calls - Fixed some wrong UNINIT_VAR() calls - Fixed a bug in generate_partition_syntax() in case of errors - Added mem_root to argument to new thread_info - Simplified my_parse_error() call in sql_yacc.yy	10 years ago
Monty	7332af49e4	- Renaming variables so that they don't shadow others (After this patch one can compile with -Wshadow and get much fewer warnings) - Changed ER(ER_...) to ER_THD(thd, ER_...) when thd was known or if there was many calls to current_thd in the same function. - Changed ER(ER_..) to ER_THD_OR_DEFAULT(current_thd, ER...) in some places where current_thd is not necessary defined. - Removing calls to current_thd when we have access to thd Part of this is optimization (not calling current_thd when not needed), but part is bug fixing for error condition when current_thd is not defined (For example on startup and end of mysqld) Notable renames done as otherwise a lot of functions would have to be changed: - In JOIN structure renamed: examined_rows -> join_examined_rows record_count -> join_record_count - In Field, renamed new_field() to make_new_field() Other things: - Added DBUG_ASSERT(thd == tmp_thd) in Item_singlerow_subselect() just to be safe. - Removed old 'tab' prefix in JOIN_TAB::save_explain_data() and use members directly - Added 'thd' as argument to a few functions to avoid calling current_thd.	10 years ago
s.sujatha	5da083ef67	Bug#20041860: SLAVE ERROR WHEN DROP DATABASE Fix: === Backport Bug#11756194 to mysql-5.5. slave breaks if 'drop database' fails on master and mismatched tables on slave. 'DROP TABLE <deleted tables>' was binlogged when 'DROP DATABASE' failed and at least one table was deleted from the database. The log event would lead slave SQL thread stop if some of the tables did not exist on slave. After this patch, It is always binlogged with 'IF EXISTS' option.	11 years ago

Michael Widenius	70823e1d91	MDEV-5120 Test suite test maria-no-logging fails The reason for the failure was a bug in an include file on debian that causes 'struct stat' to have different sized depending on the environment. This patch fixes so that we always include my_global.h or my_config.h before we include any other files. Other things: - Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few "always-include-this-file-first' files as possible. - Removed usage of some include files that where already included by my_global.h or by other files. client/mysql_plugin.c: Use my_global.h first client/mysqlslap.c: Remove duplicated include files extra/comp_err.c:

Michael Widenius	b18a1b0e6c	MDEV-5850: MySQL Bug#21317: SHOW CREATE DATABASE does not obey to lower_case_table_names Bug #3329 Incomplete lower_case_table_names=2 implementation The problem was that check_db_name() converted database names to lower case also in case of lower_case_table_names=2. Fixed by removing the conversion in check_db_name for lower_case_table_names = 2 and instead converting db name to lower case at same places as table names are converted. Fixed bug that SHOW CREATE DATABASE FOO showed information for database 'foo'. I also removed some checks of lower_case_table_names when it was enough to use table_alias_charset. mysql-test/mysql-test-run.pl: Added --use-copy argument to force mysql-test-run to copy files instead of doing symlinks. This is needed when you run with test directory on another file system mysql-test/r/lowercase_table.result: Updated results mysql-test/r/lowercase_table2.result: Updated results mysql-test/suite/parts/r/partition_mgm_lc2_innodb.result: Updated results mysql-test/suite/parts/r/partition_mgm_lc2_memory.result: Updated results mysql-test/suite/parts/r/partition_mgm_lc2_myisam.result: Updated results mysql-test/t/lowercase_table.test: Added tests with mixed case databases mysql-test/t/lowercase_table2.test: Added tests with mixed case databases sql/log.cc: Don't check lower_case_table_names when we can use table_alias_charset sql/sql_base.cc: Don't check lower_case_table_names when we can use table_alias_charset sql/sql_db.cc: Use cmp_db_names() for checking if current database changed. mysql_rm_db() now converts db to lower case if lower_case_table_names was used. Changed database options cache to use table_alias_charset. This fixed a bug where SHOW CREATE DATABASE showed wrong information. sql/sql_parse.cc: Change also db name to lower case when file names are changed. Don't need to story copy of database name anymore when lower_case_table_names == 2 as check_db_name() don't convert in this case. Updated arguments to mysqld_show_create_db(). When adding table to TABLE_LIST also convert db name to lower case if needed (same way as we do with table names). sql/sql_show.cc: mysqld_show_create_db() now also takes original name as argument for output to user. sql/sql_show.h: Updated prototype for mysqld_show_create_db() sql/sql_table.cc: In mysql_rename_table(), do same conversions to database name as we do for the file name	12 years ago

Michael Widenius	7ffc9da093	Implementation of MDEV-5491: CREATE OR REPLACE TABLE Using CREATE OR REPLACE TABLE is be identical to DROP TABLE IF EXISTS table_name; CREATE TABLE ...; Except that: * CREATE OR REPLACE is be atomic (now one can create the same table between drop and create). * Temporary tables will not shadow the table name for the DROP as the CREATE TABLE tells us already if we are using a temporary table or not. * If the table was locked with LOCK TABLES, the new table will be locked with the same lock after it's created. Implementation details: - We don't anymore open the to-be-created table during CREATE TABLE, which the original code did. - There is no need to open a table we are planning to create. It's enough to check if the table exists or not. - Removed some of duplicated code for CREATE IF NOT EXISTS. - Give an error when using CREATE OR REPLACE with IF NOT EXISTS (conflicting options). - As a side effect of the code changes, we don't anymore have to internally re-prepare prepared statements with CREATE TABLE if the table exists. - Made one code path for all testing if log table are in use. - Better error message if one tries to create/drop/alter a log table in use - Added back disabled rpl_row_create_table test as it now seams to work and includes a lot of interesting tests. - Added HA_LEX_CREATE_REPLACE to mark if we are using CREATE OR REPLACE - Aligned CREATE OR REPLACE parsing code in sql_yacc.yy for TABLE and VIEW - Changed interface for drop_temporary_table() to make it more reusable - Changed Locked_tables_list::init_locked_tables() to work on the table object instead of the table list object. Before this it used a mix of both, which was not good. - Locked_tables_list::unlock_locked_tables(THD thd) now requires a valid thd argument. Old usage of calling this with 0 i changed to instead call Locked_tables_list::reset() - Added functions Locked_tables_list:restore_lock() and Locked_tables_list::add_back_last_deleted_lock() to be able to easily add back a locked table to the lock list. - Added restart_trans_for_tables() to be able to restart a transaction. - DROP_ACL is required if one uses CREATE TABLE OR REPLACE. - Added drop of normal and temporary tables in create_table_imp() if CREATE OR REPLACE was used. - Added reacquiring of table locks in mysql_create_table() and mysql_create_like_table() mysql-test/include/commit.inc: With new code we get fewer status increments mysql-test/r/commit_1innodb.result: With new code we get fewer status increments mysql-test/r/create.result: Added testing of create or replace with timeout mysql-test/r/create_or_replace.result: Basic testing of CREATE OR REPLACE TABLE mysql-test/r/partition_exchange.result: New error message mysql-test/r/ps_ddl.result: Fewer reprepares with new code mysql-test/suite/archive/discover.result: Don't rediscover archive tables if the .frm file exists (Sergei will look at this if there is a better way...) mysql-test/suite/archive/discover.test: Don't rediscover archive tables if the .frm file exists (Sergei will look at this if there is a better way...) mysql-test/suite/funcs_1/r/innodb_views.result: New error message mysql-test/suite/funcs_1/r/memory_views.result: New error message mysql-test/suite/rpl/disabled.def: rpl_row_create_table should now be safe to use mysql-test/suite/rpl/r/rpl_row_create_table.result: Updated results after adding back disabled test mysql-test/suite/rpl/t/rpl_create_if_not_exists.test: Added comment mysql-test/suite/rpl/t/rpl_row_create_table.test: Added CREATE OR REPLACE TABLE test mysql-test/t/create.test: Added CREATE OR REPLACE TABLE test mysql-test/t/create_or_replace-master.opt: Create logs mysql-test/t/create_or_replace.test: Basic testing of CREATE OR REPLACE TABLE mysql-test/t/partition_exchange.test: Error number changed as we are now using same code for all log table change issues mysql-test/t/ps_ddl.test: Fewer reprepares with new code sql/handler.h: Moved things around a bit in a structure to get better alignment. Added HA_LEX_CREATE_REPLACE to mark if we are using CREATE OR REPLACE Added 3 elements to end of HA_CREATE_INFO to be able to store state to add backs locks in case of LOCK TABLES. sql/log.cc: Reimplemented check_if_log_table(): - Simpler and faster usage - Can give error messages This gives us one code path for allmost all error messages if log tables are in use sql/log.h: New interface for check_if_log_table() sql/slave.cc: More logging sql/sql_alter.cc: New interface for check_if_log_table() sql/sql_base.cc: More documentation Changed interface for drop_temporary_table() to make it more reusable Changed Locked_tables_list::init_locked_tables() to work on the table object instead of the table list object. Before this it used a mix of both, which was not good. Locked_tables_list::unlock_locked_tables(THD thd) now requires a valid thd argument. Old usage of calling this with 0 i changed to instead call Locked_tables_list::reset() Added functions Locked_tables_list:restore_lock() and Locked_tables_list::add_back_last_deleted_lock() to be able to easily add back a locked table to the lock list. Check for command number instead of open_strategy of CREATE TABLE was used. Added restart_trans_for_tables() to be able to restart a transaction. This was needed in "create or replace ... select" between the drop table and the select. sql/sql_base.h: Added and updated function prototypes sql/sql_class.h: Added new prototypes to Locked_tables_list class Added extra argument to select_create to avoid double call to eof() or send_error() - I needed this in some edge case where the table was not created against expections. sql/sql_db.cc: New interface for check_if_log_table() sql/sql_insert.cc: Remember position to lock information so that we can reaquire table lock for LOCK TABLES + CREATE OR REPLACE TABLE SELECT. Later add back the lock by calling restore_lock(). Removed one not needed indentation level in create_table_from_items() Ensure we don't call send_eof() or abort_result_set() twice. sql/sql_lex.h: Removed variable that I temporarly added in an earlier changeset sql/sql_parse.cc: Removed old test code (marked with QQ) Ensure that we have open_strategy set as TABLE_LIST::OPEN_STUB in CREATE TABLE Removed some IF NOT EXISTS code as this is now handled in create_table_table_impl(). Set OPTION_KEEP_LOGS later. This code had to be moved as the test for IF EXISTS has changed place. DROP_ACL is required if one uses CREATE TABLE OR REPLACE. sql/sql_partition_admin.cc: New interface for check_if_log_table() sql/sql_rename.cc: New interface for check_if_log_table() sql/sql_table.cc: New interface for check_if_log_table() Moved some code in mysql_rm_table() under a common test. - Safe as temporary tables doesn't have statistics. - !is_temporary_table(table) test was moved out from drop_temporary_table() and merged with upper level code. - Added drop of normal and temporary tables in create_table_imp() if CREATE OR REPLACE was used. - Added reacquiring of table locks in mysql_create_table() and mysql_create_like_table() - In mysql_create_like_table(), restore table->open_strategy() if it was changed. - Re-test if table was a view after opening it. sql/sql_table.h: New prototype for mysql_create_table_no_lock() sql/sql_yacc.yy: Added syntax for CREATE OR REPLACE TABLE Reuse new code for CREATE OR REPLACE VIEW sql/table.h: Added name for enum type sql/table_cache.cc: More DBUG	12 years ago

Praveenkumar Hulakund	3b1e98d218	Bug#11765252 - READ OF FREED MEMORY WHEN "USE DB" AND "SHOW PROCESSLIST" Analysis: ---------- The problem here is, if one connection changes its default db and at the same time another connection executes "SHOW PROCESSLIST", when it wants to read db of the another connection then there is a chance of accessing the invalid memory. The db name stored in THD is not guarded while changing user DB and while reading the user DB in "SHOW PROCESSLIST".

Praveenkumar Hulakund	10a6aa256e	Bug#11765252 - READ OF FREED MEMORY WHEN "USE DB" AND "SHOW PROCESSLIST" Analysis: ---------- The problem here is, if one connection changes its default db and at the same time another connection executes "SHOW PROCESSLIST", when it wants to read db of the another connection then there is a chance of accessing the invalid memory. The db name stored in THD is not guarded while changing user DB and while reading the user DB in "SHOW PROCESSLIST". So, if THD.db is freed by thd "owner" thread and if another thread executing "SHOW PROCESSLIST" statement tries to read and copy THD.db at the same time then we may endup in the issue reported here. Fix: ---------- Used mutex "LOCK_thd_data" to guard THD.db while freeing it and while copying it to processlist.	12 years ago

Igor Babaev	47fae7f08f	Added procedures to delete records by keys from statistical tables. Now when a table is dropped the statistics on the table is removed from the statistical tables. If the table is altered in such a way that a column is dropped or the type of the column is changed then statistics on the column is removed from the table column_stat. It also triggers removal of the statistics on the indexes who use this column as its component. Added procedures that changes the names of the tables or columns in the statistical tables for. These procedures are used when tables/columns are renamed. Also partly re-factored the code that introduced the persistent statistical tables. Added test cases into statistics.test to cover the new code.	14 years ago

Dmitry Shulga	bc7af17579	Fixed Bug#11756013 (formerly known as bug#47870): BOGUS "THE TABLE MYSQL.PROC IS MISSING,..." There was a race condition between loading a stored routine (function/procedure/trigger) specified by fully qualified name SCHEMA_NAME.PROC_NAME and dropping the stored routine database. The problem was that there is a window for race condition when one server thread tries to load a stored routine being executed and the other thread tries to drop the stored routine schema. This condition race window exists in implementation of function mysql_change_db() called by db_load_routine() during loading of stored routine to cache. Function mysql_change_db() calls check_db_dir_existence() that might failed because specified database was dropped during concurrent execution of DROP SCHEMA statement. db_load_routine() calls mysql_change_db() with flag 'force_switch' set to 'true' value so when referenced db is not found then my_error() is not called and function mysql_change_db() returns ok. This shadows information about schema opening error in db_load_routine(). Then db_load_routine() makes attempt to parse stored routine that is failed. This makes to return error to sp_cache_routines_and_add_tables_aux() but since during error generation a call to my_error wasn't made and hence THD::main_da wasn't set we set the generic "mysql.proc table corrupt" error when running sp_cache_routines_and_add_tables_aux(). The fix is to install an error handler inside db_load_routine() for the mysql_op_change_db() call, and check later if the ER_BAD_DB_ERROR was caught. sql/sql_db.cc: Added synchronization point "before_db_dir_check" to emulate a race condition during processing of CALL/DROP SCHEMA.	15 years ago

Jon Olav Hauglid	f94e7288e3	Bug #11765416 (former 58381) FAILED DROP DATABASE CAN BREAK STATEMENT BASED REPLICATION The first phase of DROP DATABASE is to delete the tables in the database. If deletion of one or more of the tables fail (e.g. due to a FOREIGN KEY constraint), DROP DATABASE will be aborted. However, some tables could still have been deleted. The problem was that nothing would be written to the binary log in this case, so any slaves would not delete these tables. Therefore the master and the slaves would get out of sync. This patch fixes the problem by making sure that DROP TABLE is written to the binary log for the tables that were in fact deleted by the failed DROP DATABASE statement.

Guilhem Bichot	1756d087cd	Fix for BUG#59894 "set optimizer_switch to e or d causes invalid memory writes/valgrind warnings": due to prefix support, the argument "e" was overwritten with its full value "engine_condition_pushdown", which caused a buffer overrun. This was wrong usage of find_type(); other wrong usages are fixed here too. Please start reading with the comment of typelib.c. client/mysqldump.c: A bug: find_type() expects a bitmap as 3rd argument (each bit is a flag controlling a behaviour of the function); here it was instead passed the length of the string to search! That could give random behaviour of find_type() depending on the string. We rather need to pass a correct flag to find_type(). The correct flag is FIND_TYPE_BASIC (0). Flag 8 is not needed as buff cannot have a comma (see how buff is filled). Flag 1 looks like a superfluous restriction. Flag 4 is not user-friendly (why use --compatible=2 rather than --compatible=mysql40 ?, and we probably not commit to "2" always meaning "mysql40" until the end of times). include/mysql.h.pp: This isn't a problematic API change as we go from char* to const char: existing code will run unchanged. include/typelib.h: named constants. Not an enum to not significantly change the declaration of find_type() which would be an API change (typelib.h is included in mysql.h). mysql-test/r/mysqldump.result: correct result (see the two requested modes in SQL_MODE) mysql-test/suite/sys_vars/t/optimizer_switch_basic.test: test for BUG#59894. The second SET used to crash. mysql-test/t/mysqldump.test: we had no test for multiple modes in --compatible, which is supported according to --help mysys/typelib.c: Fix for BUG#59894. parse_name() is asked to match "e" with a row of the TYPELIB (the TYPELIB lists permitted flags of optimizer_switch; and comes from optimizer_switch_names[] of sys_vars.cc). find_type() is capable of supporting prefixes, but if it is not passed flag 2 in third argument, it will overwrite its first argument (the string to search for) with the complete name, here overwriting "e" with "engine_condition_pushdown". But as this "e" was a buffer allocated in an Item, it was not big enough to host the longer name, thus the crash. We don't need to know the complete flag's name; the output used from find_type() is just the flag's number (== function's return code). So we can pass flag 2 to find_type() in parse_name(). After doing this fix and the other fixes in this patch, all usages of find_type() were using flag 2; in most usages the string to search for, is not guaranteed to be long enough to host the complete name (it is either directly from argv, or from alloc_root/my_malloc done in an earlier call). Thus, flag 2 is here made implicit: callers need not pass it anymore, it is always automatically turned on. This allows to eliminate an oddity: parse_name() took a const char, and then removed "const" before calling find_type(), which could theoretically modify the pointed data, thus lying on constness. Last, constants for find_type() are now named. sql-common/client.c: Two bugs: 1) The enum was not in sync with the array (due to a bad porting of WL 1054; the extra OPT_ values are about options present in 5.1 and deleted in 5.5); added a compile_time_assert() to make sure this doesn't happen again 2) find_type() was writing past the end of opt_arg; as opt_arg was allocated with alloc_root() with no extra space, this was an overrun; it could be seen when * building with -DWITH_VALGRIND -DHAVE_purify -DEXTRA_DEBUG ** making execution go through the faulty code; this faulty code is executed only if the client asks to read a configuration file like this: mysql_options(mysql, MYSQL_READ_DEFAULT_FILE, "/tmp/cnf.cnf"); so by adding such line to the start of mysql_client_test.c::client_connect(), we could see the valgrind warning: ==30548== Invalid write of size 1 ==30548== at 0x4C2624C: strcpy (mc_replace_strmem.c:303) ==30548== by 0x48DC29: find_type (typelib.c:120) ==30548== by 0x465686: mysql_read_default_options (client.c:1344) ==30548== by 0x46830F: mysql_real_connect (client.c:2971) ==30548== by 0x409339: client_connect (mysql_client_test.c:331) ==30548== by 0x463A7F: main (mysql_client_test.c:19902) ==30548== Address 0x61875ad is 0 bytes after a block of size 29 alloc'd ==30548== at 0x4C25153: malloc (vg_replace_malloc.c:195) ==30548== by 0x49BFF1: my_malloc (my_malloc.c:38) ==30548== by 0x49C65C: alloc_root (my_alloc.c:166) ==30548== by 0x48EF97: handle_default_option (default.c:381) ==30548== by 0x49068C: search_default_file_with_ext (default.c:992) ==30548== by 0x48F929: search_default_file (default.c:670) ==30548== by 0x48EDC4: my_search_option_files (default.c:312) ==30548== by 0x48F4B1: my_load_defaults (default.c:576) ==30548== by 0x46517A: mysql_read_default_options (client.c:1207) ==30548== by 0x46830F: mysql_real_connect (client.c:2971) ==30548== by 0x409339: client_connect (mysql_client_test.c:331) ==30548== by 0x463A7F: main (mysql_client_test.c:19902) This is fixed by having find_type() not overwrite anymore. sql/sql_help.cc: cast not needed anymore. sql/table.cc: cast not needed anymore.	15 years ago
