fix binlog-writing so that end_log_pos is given correctly even within transactions for both SHOW BINLOG and SHOW MASTER STATUS, that is as absolute values (from log start) rather than relative values (from transaction's start). --- Merge tnurnberg@bk-internal.mysql.com:/home/bk/mysql-5.0-maint into sin.intern.azundris.com:/home/tnurnberg/22540/50-22540

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.

Problem: long and long long types mess in a comparison may lead to wrong results on some platforms. Fix: prefer [unsigned] long long as [u]longlong as it's used unconditionally in many places.

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.
