"REPLACE/INSERT IGNORE/UPDATE IGNORE doesn't work" Federated does not record neccessary HA_EXTRA flags in order to support REPLACE/INSERT IGNORE/UPDATE IGNORE. Implement ::extra() to capture flags neccessary for functionality. New function append_ident() to better escape identifiers consistantly.

the loose scan optimization for grouping queries was applied returned a wrong result set when the query was used with the SQL_BIG_RESULT option. The SQL_BIG_RESULT option forces to use sorting algorithm for grouping queries instead of employing a suitable index. The current loose scan optimization is applied only for one table queries when the suitable index is covering. It does not make sense to use sort algorithm in this case. However the create_sort_index function does not take into account the possible choice of the loose scan to implement the DISTINCT operator which makes sorting unnecessary. Moreover the current implementation of the loose scan for queries with distinct assumes that sorting will never happen. Thus in this case create_sort_index should not call the function filesort.

INSERT into table from SELECT from the same table with ORDER BY and LIMIT was inserting other data than sole SELECT ... ORDER BY ... LIMIT returns. One part of the patch for bug #9676 improperly pushed LIMIT to temporary table in the presence of the ORDER BY clause. That part has been removed.

The C optimizer may decide that data access operations through pointer of different type are not related to the original data (strict aliasing). This is what happens in fetch_long_with_conversion(), when called as part of mysql_stmt_fetch() : it tries to check for truncation errors by first storing float (and other types of data) into a char * buffer and then accesses them through a float pointer. This is done to prevent the effects of excess precision when using FPU registers. However the doublestore() macro converts a double pointer to an union pointer. This violates the strict aliasing rule. Fixed by making the intermediary variables volatile ( to not re-introduce the excess precision bug) and using the intermediary value instead of the char * buffer. Note that there can be loss of precision for both signed and unsigned 64 bit integers converted to double and back, so the check must stay there (even for compatibility reasons). Based on the excellent analysis in bug 28400.

The reason the "reap;" succeeds unexpectedly is because the query was completing(almost always) and the network buffer was big enough to store the query result (sometimes) on Windows, meaning the response was completely sent before the server thread could be killed. Therefore we use a much longer running query that doesn't have a chance to fully complete before the reap happens, testing the kill properly.

- When creating an index for the sort, the number of rows plus 1 is used to allocate a buffer. In this test case, the number of rows 4294967295 is the max value of an unsigned integer, so when 1 was added to it, a buffer of size 0 was allocated causing the crash. - Create new test suite for this bug's test suite as per QA.

long shared-memory-base-names could overflow a static internal buffer and thus crash mysqld and various clients. change both to dynamic buffers, show everything but overflowing those buffers still works. The test case for this would pretty much amount to mysqld --shared-memory-base-name=HeyMrBaseNameXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX --shared-memory=1 & mysqladmin --no-defaults --shared-memory-base-name=HeyMrBaseNameXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX shutdown Unfortunately, we can't just use an .opt file for the server. The .opt file is used at start-up, before any include in the actual test can tell mysqltest to skip this one on non-Windows. As a result, such a test would break on unices. Fixing mysql-test-run.pl to export full path for master and slave would enable us to start a server from within the test which is ugly and, what's more, doesn't work as the server blocks (mysqltest offers no fire-and-forget fork-and-exec), and mysqladmin never gets run. Making the test rpl_windows_shm or some such so we can is beyond ugly. As is introducing another file-name based special case (run "win*.test" only when on Windows). As is (yuck) coding half the test into mtr (as in, having it hand out a customized environment conductive to the shm- thing on Win only). Situation is exacerbated by the fact that .sh is not necessary run as expected on Win. In short, it's just not worth it. No test-case until we have a new-and-improved test framework.

Occasionally mysqlbinlog --hexdump failed with error: ERROR 1064 (42000) at line ...: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'Query thread_id=... exec_time=... error_code=... When the length of hexadecimal dump of binlog header was divisible by 16, commentary sign '#' after header was lost. The Log_event::print_header function has been modified to always finish hexadecimal binlog header with "\n# ".

The abort happened when a query contained a conjunctive predicate of the form 'view column = constant' in the WHERE condition and the grouping list also contained a reference to a view column yet a different one. Removed the failing assertion as invalid in a general case. Also fixed a bug that prevented applying some optimization for grouping queries using views. If the WHERE condition of such a query contains a conjunctive condition of the form 'view column = constant' and this view column is used in the grouping list then grouping by this column can be eliminated. The bug blocked performing this elimination.

and replicated): A DROP USER statement with a non-existing user was correctly written to the binary log (there might be users that were removed, but not all), but the error code was not set, which caused the slave to stop with an error. The error reporting code was moved to before the statement was logged to ensure that the error information for the thread was correctly set up. This works since my_error() will set the fields net.last_errno and net.last_error for the thread that is reporting the error, and this will then be picked up when the Query_log_event is created and written to the binary log.
