Original problem was fixed by Magnus (see BUG25807).

Currently only windows debug build causes assertion failure. This patch assures
that my_tell gets correct file descriptor on any platform by DBUG_ASSERT macro.


mysys/my_seek.c:
  Added assertion in case my_tell gets wrong file descriptor.

            corruption errors: 126,134,145

When one thread attempts to lock two (or more) tables and another
thread executes statement that aborts these locks (e.g. REPAIR
TABLE) we may get a table object with wrong lock type in a table
cache.

For example if SELECT FROM t1,t2 was aborted, subsequent INSERT
INTO t1 may be executed under read lock.

As a result we may get various table corruptions and even a server
crash.

This is fixed by resetting lock type in case lock was aborted by
another thread.

I failed to create reasonable test case for this bug.


sql/lock.cc:
  If thr_multi_lock was aborted by another thread, it unlocks tables
  that were locked before one that was aborted. Lock type for tables
  that were after a table that was aborted preserved. Thus we need
  to reset lock data in case thr_multi_lock was aborted.

Setting a key_cache_block_size which is not a power of 2
could corrupt MyISAM tables.

A couple of computations in the key cache code use bit
operations which do only work if key_cache_block_size
is a power of 2.

Replaced bit operations by arithmetic operations
to make key cache able to handle block sizes that are
not a power of 2.


include/keycache.h:
  Bug#28478 - Improper key_cache_block_size corrupts MyISAM tables
  Removed element 'key_cache_shift' from KEY_CACHE after
  the changes in mf_keycache.c made it unused.
