In create_myisam_from_heap() mark all errors as fatal except HA_ERR_RECORD_FILE_FULL for a HEAP table. Not doing so could lead to problems, e.g. in a case when a temporary MyISAM table gets overrun due to its MAX_ROWS limit while executing INSERT/REPLACE IGNORE ... SELECT. The SELECT execution was aborted, but the error was converted to a warning due to IGNORE clause, so neither 'ok' nor 'error' packet could be sent back to the client. This condition led to hanging client when using 5.0 server, or assertion failure in 5.1. mysql-test/r/insert_select.result: Added a test case for bug #46075. mysql-test/t/insert_select.test: Added a test case for bug #46075. sql/sql_select.cc: In create_myisam_from_heap() mark all errors as fatal except HA_ERR_RECORD_FILE_FULL for a HEAP table.

Problem was that a failing rename just left the partitions at the state it was at the failure. Solution was to try to revert the started rename if a failure occured. mysql-test/r/partition_not_embedded.result: Bug#30102: Rename table does corrupt tables with partition files on failure New result file mysql-test/t/partition_not_embedded.test: Bug#30102: Rename table does corrupt tables with partition files on failure New test file (list_files does not report the files in embedded) sql/ha_partition.cc: Bug#30102: Rename table does corrupt tables with partition files on failure Better error handling for rename partitions (reverting the started rename operation) Different order of files for delete. sql/handler.cc: Bug#30102: Rename table does corrupt tables with partition files on failure Tries to remove as many table files as possible if the first delete succeeds.

not logged Errors encountered during initialization of the SSL subsystem are printed to stderr, rather than to the error log. This patch adds a parameter to several SSL init functions to report the error (if any) out to the caller. The function init_ssl() in mysqld.cc is moved after the initialization of the log subsystem, so that any error messages can be logged to the error log. Printing of messages to stderr has been retained to get diagnostic output in a client context. include/violite.h: Adding an enumeration for the various errors that can occur during initialization of the SSL module. sql/mysqld.cc: Adding more logging of SSL init errors, and moving init_ssl() till after initialization of logging subsystem. vio/viosslfactories.c: Define error strings, provide an access method for these strings, and maintain an error parameter in several funcs to return the error (if any) to the caller.

binlog The fix for BUG 43929 introduced a regression issue. In a nutshell, when a statement that changes a non-transactional table fails, it is written to the binary log with the error code appended. Unfortunately, after BUG 43929, this failure was flushing the transactional chace causing mismatch between execution and logging histories. To fix this issue, we avoid flushing the transactional cache when a commit or rollback is not issued.

When during the optimization an item is moved to the upper select the item's context left unchanged. This caused wrong result in the PS/SP mode. The Item_ident::remove_dependence_processor now sets the context of the select to which the item is moved to. mysql-test/r/subselect.result: The test case for the bug#46051 is adjusted. mysql-test/t/subselect.test: The test case for the bug#46051 is adjusted. sql/item.cc: Bug#46051: Incorrectly market field caused wrong result. The Item_ident::remove_dependence_processor now sets the context of the select to which the item is moved to.

In a subselect all fields from outer selects are marked as dependent on selects they are belong to. In some cases optimizer substitutes it for an equivalent expression. For example "a_field IN (SELECT outer_field)" is substituted with "a_field = outer_field". As we moved the outer_field to the upper select it's not really outer anymore. But it was left marked as outer. If exists an index over a_field optimizer choose wrong execution plan and thus return wrong result. Now the Item_in_subselect::single_value_transformer function removes dependent marking from fields when a subselect is optimized away. mysql-test/r/subselect.result: Added a test case for the bug#46051. mysql-test/t/subselect.test: Added a test case for the bug#46051. sql/item_subselect.cc: Bug#46051: Incorrectly market field caused wrong result. Now the Item_in_subselect::single_value_transformer function removes dependent marking from fields when a subselect is optimized away.

The "get_master_version_and_clock(...)" function in sql/slave.cc ignores error and passes directly when queries fail, or queries succeed but the result retrieved is empty. The "get_master_version_and_clock(...)" function should try to reconnect master if queries fail because of transient network problems, and fail otherwise. The I/O thread should print a warning if the some system variables do not exist on master (very old master) mysql-test/extra/rpl_tests/rpl_get_master_version_and_clock.test: Added test file for bug #45214 mysql-test/suite/rpl/r/rpl_get_master_version_and_clock.result: Added test result for bug #45214 mysql-test/suite/rpl/t/rpl_get_master_version_and_clock.test: Added test file for bug #45214 sql/slave.cc: The 'is_network_error()' function is added for checking if the error is caused by network. Added a new return value (2) to 'get_master_version_and_clock()' function result set to indicate transient network errors when queries fail, and the caller should try to reconnect in this case.

table The MERGE table storage engine does not support the HA_CAN_SQL_HANDLE feature and any attempt to open the merge table will fail with ER_ILLEGAL_HA. After an error occurred the tables that was opened must be closed again or they will be left in an inconsistent state. However, the assumption made in the code for closing and register handler tables was that only one table will be opened, and this is not true for MERGE tables which will cause multiple tables to open. The next time a SELECT operation was issued on the merge table it caused the system to freeze. This patch fixes this issue by making sure that all tables which are opened also are closed in the event of an error. mysql-test/r/merge.result: Added test case for bug 45781 mysql-test/t/merge.test: Added test case for bug 45781 sql/sql_handler.cc: * mysql_ha_open() was never ment to open more than one table. If we encounter more tables, we should close all tables related to the current substatement and raise an exception.

failed" Do not assume that SQL prepared statements always run in text protocol. When invoked from a stored procedure, which is itself invoked by means of prepared CALL statement, the protocol may be binary. Juggle with the protocol only when we want to change it to binary in COM_STMT_EXECUTE, COM_STMT_PREPARE. This is a backport from 5.4/6.0, where the bug was fixed as part of WL#4264 "Backup: Stabilize Service Interface"

Fixed the following problems: 1. cmake 2.6 warning because of a changed default on how the dependencies to libraries with a specified path are resolved. Fixed by requiring cmake 2.6. 2. Removed an obsolete pre-NT4 hack including defining Windows system defines to alter the behavior of windows.h. 3. Disabled warning C4065 on compiling sql_yacc.cc because of a know incompatibility in some of the newer bison binaries.
