revno: 3249 committer: Alfranio Correia <alfranio.correia@oracle.com> branch nick: mysql-5.5.18-release timestamp: Wed 2011-11-02 15:28:18 +0000 message: BUG#13337202 - REPLICATION PERFORMANCE DROP DUE TO "THE BINLOG MAY BE CORRUPTED" FLOOD In patch mysql-5.5:revno:3097.92.133, we made the gcc 4.6.1 compiler to stop complaining about the fact that binlog_can_be_corrupted was defined but not used. The fix consisted in checking the variable and printing a warning message. However, the fix caused a regression as a message was being printed out when there was no corrupted binary log causing performance problems and triggering users' suspicions when there was no need. In BUG#13337202, we do not print any message and use the variable in an "if" with an empty body to keep the compiler happy. ------------------------------------------------------------ revno: 3248 [merge] tags: clone-5.5.18-build committer: Marko M?kel? <marko.makela@oracle.com> branch nick: mysql-5.5-security timestamp: Wed 2011-10-26 12:28:40 +0300 message: Null merge from mysql-5.1-security. ------------------------------------------------------------ revno: 2661.768.36 committer: Marko M?kel? <marko.makela@oracle.com> branch nick: mysql-5.1-security timestamp: Wed 2011-10-26 12:23:57 +0300 message: Revert revno:3452.71.32 (Bug#12612184 fix).

This bug was introduced in the InnoDB Plugin when implementing support for ROW_FORMAT=DYNAMIC. Additionally, the data type information was not initialized, but apparently it has never been needed in this case. Nevertheless, it is not good programming practice to pass uninitialized values around. calc_row_difference(): Declare the update field uninitialized in Valgrind. Copy the data type information as well, except when the field is SQL NULL. In the built-in InnoDB, initialize ufield->extern_storage = FALSE (an initialization bug that had gone unnoticed this far). The InnoDB Plugin and later have this flag to dfield_t and have always initialized it properly. row_ins_cascade_calc_update_vec(): Reduce the scope of some pointers. Initialize orig_len. (This caused the bug in InnoDB Plugin and later.) row_ins_foreign_check_on_constraint(): Simplify a condition. Declare the update vector uninitialized. rb:771 approved by Jimmy Yang ------------------------------------------------------------ revno: 3245 [merge] committer: Vasil Dimov <vasil.dimov@oracle.com> branch nick: mysql-5.5-security timestamp: Tue 2011-10-25 16:48:23 +0300 message: Merge mysql-5.1-security -> mysql-5.5-security (Fix Bug#12661768) ------------------------------------------------------------ revno: 2661.768.30 committer: Vasil Dimov <vasil.dimov@oracle.com> branch nick: mysql-5.1-security timestamp: Tue 2011-10-25 16:46:38 +0300 message: Fix Bug#12661768 UPDATE IGNORE CRASHES SERVER IF TABLE IS INNODB AND IT IS PARENT FOR OTHER ONE Do not try to lookup key_nr'th key in 'table' because there may not be such a key there. key_nr is the number of the key in the _child_ table name, not in the parent table. Instead just print the fields of the record that are covered by the first key defined on the parent table. This bug gets a better fix in MySQL 5.6, which is too risky for 5.1 and 5.5.

During the process of opening tables for a statement, we allocated memory which was used only during view loading even in cases when the statement didn't use any views. Such an unnecessary allocation (and corresponding freeing) might have caused significant performance overhead in some workloads. For example, it caused up to 15% slowdown in a simple stored routine calculating Fibonacci's numbers. This memory was pre-allocated as part of "new_frm_mem" MEM_ROOT initialization at the beginning of open_tables(). This patch addresses this issue by turning off memory pre-allocation during initialization for this MEM_ROOT. Now, memory on this root will be allocated only at the point when the first .FRM for a view is opened. The patch doesn't contain a test case since it is hard to test the performance improvements or the absence of memory allocation in our test framework. ------------------------------------------------------------ revno: 3097.92.143 [merge] committer: Ashish Agarwal<ashish.y.agarwal@oracle.com> branch nick: bug_793_5.5 timestamp: Sat 2011-10-22 17:04:38 +0530 message: bug#11758979 - 51252: ARCHIVE TABLES STILL FAIL UNDER STRESS TESTS: CRASH, CORRUPTION, 4G MEMOR Issue: Valgrind errors due to checksum and optimize query against archive tables with null columns.
