When using concurrent insert with parallel index reads, it could happen that reading sessions found keys that pointed to records yet to be written to the data file. The result was a report of a corrupted table. But it was false alert. When inserting a record in a table with indexes, the keys are inserted into the indexes before the record is written to the data file. When the insert happens concurrently to selects, an index read can find a key that references the record that is not yet written to the data file. To avoid any access to such record, the select saves the current end of file position when it starts. Since concurrent inserts are always appended at end of the data file, the select can easily ignore any concurrently inserted record. The problem was that the ignore was only done for non-exact key searches (partial key or using >, >=, < or <=). The fix is to ignore concurrently inserted records also for exact key searches. No test case. Concurrent inserts cannot be tested with the test suite. Test cases are attached to the bug report. myisam/mi_rkey.c: Bug#29838 - myisam corruption using concurrent select ... and update Fixed mi_rkey() to always ignore records beyond saved eof.

INSERT/DELETE/UPDATE followed by ALTER TABLE within LOCK TABLES may cause table corruption on Windows. That happens because ALTER TABLE writes outdated shared state info into index file. Fixed by removing obsolete workaround. Affects MyISAM tables on Windows only. myisam/mi_extra.c: On windows when mi_extra(HA_EXTRA_PREPARE_FOR_DELETE) is called, we release external lock and close index file. If we're in LOCK TABLES, MyISAM state info doesn't get updated until UNLOCK TABLES. That means when we release external lock and we're in LOCK TABLES, we may write outdated state info. As SQL layer closes all table instances, we do not need this workaround anymore. mysql-test/r/alter_table.result: A test case for BUG#29957. mysql-test/t/alter_table.test: A test case for BUG#29957.

"Federated Denial of Service" Federated storage engine used to attempt to open connections within the ::create() and ::open() methods which are invoked while LOCK_open mutex is being held by mysqld. As a result, no other client sessions can open tables while Federated is attempting to open a connection. Long DNS lookup times would stall mysqld's operation and a rogue connection string which connects to a remote server which simply stalls during handshake can stall mysqld for a much longer period of time. This patch moves the opening of the connection much later, when the federated actually issues queries, by which time the LOCK_open mutex is no longer being held. mysql-test/r/federated.result: change of test/results due to patch for bug25679 mysql-test/t/federated.test: change of test/results due to patch for bug25679 sql/ha_federated.cc: bug25679 remove function check_foreign_fata_source() ha_federated::open() no longer opens the federated connection. ha_federated::create() no longer opens and tests connection. ha_federated::real_connect() opens connection and tests presence of table. ha_federated::real_query() sends query, calling real_connect() if neccessary. sql/ha_federated.h: bug25679 new methods real_query() and real_connect()

When the SQL_BIG_RESULT flag is specified SELECT should store items from the select list in the filesort data and use them when sending to a client. The get_addon_fields function is responsible for creating necessary structures for that. But this function was allowed to do so only for SELECT and INSERT .. SELECT queries. This makes the SQL_BIG_RESULT useless for the CREATE .. SELECT queries. Now the get_addon_fields allows storing select list items in the filesort data for the CREATE .. SELECT queries. mysql-test/t/create.test: Added a test case for the bug#15130: CREATE .. SELECT was denied to use advantages of the SQL_BIG_RESULT. mysql-test/r/create.result: Added a test case for the bug#15130: CREATE .. SELECT was denied to use advantages of the SQL_BIG_RESULT. sql/filesort.cc: Bug#15130: CREATE .. SELECT was denied to use advantages of the SQL_BIG_RESULT. Now the get_addon_fields allows storing select list items in the filesort data for the CREATE .. SELECT queries.

"getGeneratedKeys() does not work with FEDERATED table" mysql_insert() expected the storage engine to update the row data during the write_row() operation with the value of the new auto- increment field. The field must be updated when only one row has been inserted as mysql_insert() would ignore the thd->last_insert. This patch implements HA_STATUS_AUTO support in ha_federated::info() and ensures that ha_federated::write_row() does update the row's auto-increment value. The test case was written in C as the protocol's 'id' value is accessible through libmysqlclient and not via SQL statements. mysql-test-run.pl was extended to enable running the test binary. mysql-test/mysql-test-run.pl: bug25714 implement support to run C test for bug25714 sql/ha_federated.cc: bug25714 The storage engine instance property auto_increment_value was not being set. mysql_insert() requires that the storage engine updates the row with the auto-increment value, especially when only inserting one row.

If a primary key is defined over column c of enum type then the EXPLAIN command for a look-up query of the form SELECT * FROM t WHERE c=0 said that the query was with an impossible where condition though the query correctly returned non-empty result set when the table indeed contained rows with error empty strings for column c. This kind of misbehavior was due to a bug in the function Field_enum::store(longlong,bool) that erroneously returned 1 if the the value to be stored was equal to 0. Note that the method Field_enum::store(const char *from,uint length,CHARSET_INFO *cs) correctly returned 0 if a value of the error empty string was stored. mysql-test/r/type_enum.result: Added a test case for bug #29661. mysql-test/t/type_enum.test: Added a test case for bug #29661. sql/field.cc: Fixed bug #29611.

This bug manifested itself for join queries with GROUP BY and HAVING clauses whose SELECT lists contained DISTINCT. It occurred when the optimizer could deduce that the result set would have not more than one row. The bug could lead to wrong result sets for queries of this type because HAVING conditions were erroneously ignored in some cases in the function remove_duplicates. mysql-test/r/having.result: Added a test case for bug #29911. mysql-test/t/having.test: Added a test case for bug #29911.

After dumping triggers mysqldump copied the value of the OLD_SQL_MODE variable to the SQL_MODE variable. If the --compact option of the mysqldump was not set the OLD_SQL_MODE variable had the value of the uninitialized SQL_MODE variable. So usually the NO_AUTO_VALUE_ON_ZERO option of the SQL_MODE variable was discarded. This fix is for non-"--compact" mode of the mysqldump, because mysqldump --compact never set SQL_MODE to the value of NO_AUTO_VALUE_ON_ZERO. The dump_triggers_for_table function has been modified to restore previous value of the SQL_MODE variable after dumping triggers using the SAVE_SQL_MODE temporary variable. client/mysqldump.c: Fixed bug #29788. The dump_triggers_for_table function has been modified to restore previous value of the SQL_MODE variable after dumping triggers using the SAVE_SQL_MODE temporary variable. mysql-test/r/mysqldump.result: Updated test case for bug #29788. mysql-test/t/mysqldump.test: Updated test case for bug #29788.

ORDER BY primary_key on InnoDB table Queries that use an InnoDB secondary index to retrieve data don't need to sort in case of ORDER BY primary key if the secondary index is compared to constant(s). They can also skip sorting if ORDER BY contains both the the secondary key parts and the primary key parts (in that order). This is because InnoDB returns the rows in order of the primary key for rows with the same values of the secondary key columns. Fixed by preventing temp table sort for the qualifying queries. mysql-test/r/innodb_mysql.result: Bug #28591: test case mysql-test/t/innodb_mysql.test: Bug #28591: test case sql/sql_select.cc: Bug #28591: Use the primary key as suffix when testing if the key can be used for ORDER BY on supporting engines. sql/table.cc: Bug #28591: can use the primary key as a suffix for the secondary keys
