Fix Bug #18559 "log tables cannot change engine, and gets deadlocked when dropping w/ log on" Log tables rely on concurrent insert machinery to add data. This means that log tables are always opened and locked by special (artificial) logger threads. Because of this, the thread which tries to drop a log table starts to wait for the table to be unlocked. Which will happen only if the log table is disabled. Alike situation happens if one tries to alter a log table. However in addition to the problem above, alter table calls check_if_locking_is_allowed() routine for the engine. The routine does not allow alter for the log tables. So, alter doesn't start waiting forever for logs to be disabled, but returns with an error. Another problem is that not all engines could be used for the log tables. That's because they need concurrent insert. In this patch we: (1) Explicitly disallow to drop/alter a log table if it is currently used by the logger. (2) Update MyISAM to support log tables (3) Allow to drop log tables/alter log tables if log is disabled At the same time we (4) Disallow to alter log tables to unsupported engine (after this patch CSV and MyISAM are alowed) Recommit with review fixes. mysql-test/r/log_tables.result: Update result file. Note: there are warnings in result file. This is because of CSV bug (Bug #21328). They should go away after it is fixed. mysql-test/t/log_tables.test: Add a test for the bug sql/ha_myisam.cc: Add log table handling to myisam: as log tables use concurrent insert, they are typically locked with TL_CONCURRERENT_INSERT lock. So, disallow other threads to attempt locking of the log tables in incompatible modes. Because otherwise the threads will wait for the tables to be unlocked forever. sql/handler.cc: Add a function to check if a table we're going to lock is a log table and if the lock mode we want allowed sql/handler.h: Add a new function to check compatibility of the locking sql/log.cc: we shouldn't close the log table if and only if this particular table is already closed sql/log.h: add new functions to check if a log is enabled sql/share/errmsg.txt: add new error messages sql/sql_table.cc: DROP and ALTER TABLE should not work on log tables if the log tables are enabled storage/csv/ha_tina.cc: move function to check if the locking for the log tables allowed to handler class, so that we can reuse it in other engines. storage/myisam/mi_extra.c: add new ::extra() flag processing to myisam storage/myisam/mi_open.c: init log table flag storage/myisam/mi_write.c: update status after each write if it's a log table storage/myisam/myisamdef.h: Add new log table flag to myisam share. We need it to distinguish between usual and log tables, as for the log tables we should provide concurrent insert in a different way than for usual tables: we want new rows to be immediately visible to other threads.

alter table mysql.slow_log engine=archive;
ERROR HY000: This storage engine cannot be used for log tables"
Fix Bug #18559 "log tables cannot change engine, and gets deadlocked when dropping w/ log on" Log tables rely on concurrent insert machinery to add data. This means that log tables are always opened and locked by special (artificial) logger threads. Because of this, the thread which tries to drop a log table starts to wait for the table to be unlocked. Which will happen only if the log table is disabled. Alike situation happens if one tries to alter a log table. However in addition to the problem above, alter table calls check_if_locking_is_allowed() routine for the engine. The routine does not allow alter for the log tables. So, alter doesn't start waiting forever for logs to be disabled, but returns with an error. Another problem is that not all engines could be used for the log tables. That's because they need concurrent insert. In this patch we: (1) Explicitly disallow to drop/alter a log table if it is currently used by the logger. (2) Update MyISAM to support log tables (3) Allow to drop log tables/alter log tables if log is disabled At the same time we (4) Disallow to alter log tables to unsupported engine (after this patch CSV and MyISAM are alowed) Recommit with review fixes. mysql-test/r/log_tables.result: Update result file. Note: there are warnings in result file. This is because of CSV bug (Bug #21328). They should go away after it is fixed. mysql-test/t/log_tables.test: Add a test for the bug sql/ha_myisam.cc: Add log table handling to myisam: as log tables use concurrent insert, they are typically locked with TL_CONCURRERENT_INSERT lock. So, disallow other threads to attempt locking of the log tables in incompatible modes. Because otherwise the threads will wait for the tables to be unlocked forever. sql/handler.cc: Add a function to check if a table we're going to lock is a log table and if the lock mode we want allowed sql/handler.h: Add a new function to check compatibility of the locking sql/log.cc: we shouldn't close the log table if and only if this particular table is already closed sql/log.h: add new functions to check if a log is enabled sql/share/errmsg.txt: add new error messages sql/sql_table.cc: DROP and ALTER TABLE should not work on log tables if the log tables are enabled storage/csv/ha_tina.cc: move function to check if the locking for the log tables allowed to handler class, so that we can reuse it in other engines. storage/myisam/mi_extra.c: add new ::extra() flag processing to myisam storage/myisam/mi_open.c: init log table flag storage/myisam/mi_write.c: update status after each write if it's a log table storage/myisam/myisamdef.h: Add new log table flag to myisam share.

Fix for Bug #17544 "Cannot do atomic log rotate", Bug #21785 "Server crashes after rename of the log table" and Bug #21966 "Strange warnings on create like/repair of the log tables" According to the patch, from now on, one should use RENAME to perform a log table rotation (this should also be reflected in the manual). Here is a sample: use mysql; CREATE TABLE IF NOT EXISTS general_log2 LIKE general_log; RENAME TABLE general_log TO general_log_backup, general_log2 TO general_log; The rules for Rename of the log tables are following: IF 1. Log tables are enabled AND 2. Rename operates on the log table and nothing is being renamed to the log table. DO 3. Throw an error message. ELSE 4. Perform rename. The very RENAME query will go the the old (backup) table. This is consistent with the behavoiur we have with binlog ROTATE LOGS statement. Other problems, which are solved by the patch are: 1) Now REPAIR of the log table is exclusive operation (as it should be), this also eliminates lock-related warnings. and 2) CREATE LIKE TABLE now usese usual read lock on the source table rather then name lock, which is too restrictive. This way we get rid of another log table-related warning, which occured because of the above fact (as a side-effect, name lock resulted in a warning). mysql-test/r/log_tables.result: update result file mysql-test/t/log_tables.test: Add tests for the bugs sql/handler.cc: update comment sql/handler.h: update function to reflect changes in log tables locking logic. sql/lock.cc: Now we allow locking of the log tables for "privileged" threads Privileged thread must explicitly close and lock log tables. This is required for admin operations such as REPAIR. sql/log.cc: Changes to the file: 1) Add checks for table schema. It's more important now, as we allow rename of the log tables. Since we should check for schema when writing to a log table. E.g. if one created a table with one-only comlumn and renamed it to general_log, the server should cope with it. 2) refactor LOGGER::flush(), so that we can now use the same machinery as we use in FLUSH LOGS in other statements: whenever we have to perform a serious operation on the log tables, we have to (a) lock logger, which blocks other concurrent statements (such as selects) (b) close logs. Then perform an exclusive operation, c) reenable logs and d) unlock logger. 3) Add a function to check if a given table is a log table. 4) Add support for "privileged" thread 5) merge is_[general/slow]_log_table_enabled() into one function. 6) Add new function: reopen _log_tables, which reopens the tables, which were enabled (after temporary close, required for admin operation) sql/log.h: 1) add a new call close_n_lock_tables(). Now we use it instead of LOGGER::flush() in FLUSH LOGS implementation. 2) add a prototype for the function to check if a given table is a log table; 3) add privileged table flag to table logger 4) merge is_[general/slow]_log_table_enabled() into one function. sql/mysql_priv.h: move log table defines to log.h sql/sql_delete.cc: use new function check_if_log_table() instead of direct strcmp sql/sql_rename.cc: Traverse the list of tables in mysql_rename_tables to make sure that log tables are processed correctly (that is, according to the rules specified in the main CS comment) sql/sql_table.cc: 1) mysql_admin_table() should disable logs if it performs exclusive admin operation on a log table. This way we also eliminate warning on REPAIR of the log table. 2) mysql_create_like_table should read-lock the source table instead getting name lock on it. Name lock is too restrictive in this case. sql/share/errmsg.txt: Add a new error message for rename of the log tables sql/table.cc: use new function instead of direct strcmp. change my_strcasecmp() -> strcmp(), when comparing system db and table names storage/csv/ha_tina.cc: update function to reflect changes in log tables locking logic. storage/myisam/ha_myisam.cc: update function to reflect changes in log tables locking logic.
