MySQL (64-bit)

What's new in this version:

Bug Fixed:
- Replication: When DML invokes a trigger or a stored function that inserts into an AUTO_INCREMENT column, that DML has to be marked as an unsafe statement. If the tables are locked in the transaction prior to the DML statement (for example by using LOCK TABLES), then the DML statement was not being marked as an unsafe statement. The fix ensures that such DML statements are marked correctly as unsafe
- Replication: DROP TABLE statements are regenerated by the server before being written to the binary log. If a table or database name contained a non-regular character, such as non-latin characters, the regenerated statement was using the wrong name, breaking replication. The fix ensures that in such a case the regenerated name is correctly converted back to the original character set. Also during work on this bug, it was discovered that in the rare case that a table or database name contained 64 characters, the server was throwing an assert(M_TBLLEN < 128) assertion. The assertion has been corrected to be less than or equal 128
- Data corruption or a server exit could occur if a stored procedure had a variable declared as TEXT or BLOB and data was copied to that variable using SELECT ... INTO syntax from a TEXT or BLOB column
- CREATE TEMPORARY TABLE .. SELECT statements involving BIT columns that resulted in a column type redefinition could cause a server exit or an improperly created table
- Added Microsoft Visual Studio 2015 support. Changes include using the native (added in VS 2015) timespec library if it exists, renamed lfind/lsearch and timezone/tzname to avoid redefinition problems, set TMPDIR to "" by default as P_tmpdir no longer exists, deprecated std::hash_map in favor of std::unordered_map, and added Wix Toolset 3.10 support
- When an invalid date was supplied to the UNIX_TIMESTAMP() function using the STR_TO_DATE() function, no check was performed before converting it to a timestamp value
- With LOCK TABLES in force, an attempt to open a temporary MERGE table consisting of a view in its list of tables (not the last table in the list) caused a server exit
- For certain prepared statements, the optimizer could transform join conditions such that it used a pointer to a temporary table field that was no longer available after the initial execution. Subsequent executions caused a server exit
- Repeated execution of ALTER TABLE v1 CHECK PARTITION as a prepared statement, where v1 is a view, led to a server exit
- In addition, output for some administrative operations, when they are attempted on a view, changes from “Corrupt” to “Operation failed”. These include ANALYZE TABLE, OPTIMIZE TABLE, and REPAIR TABLE, and ALTER TABLE statements that perform ANALYZE PARTITION, CHECK PARTITION, OPTIMIZE PARTITION, and REPAIR PARTITION operations
- Using systemd to start mysqld failed if configuration files contained multiple datadir lines. Now the last datadir line is used
