Patch by: Monty Taylor <mtaylor@mysql.com>
Fixes by: Stewart Smith
Added the ability to run ndb_size.pl on mulitple databases and also to exclude lists of databases and tables from analysis.
---
Added schema name information to index table calculations as well.
---
Made database an optional parameter, the exclusion of which causes all databases to be examined.
If selecting from information_schema fails, attempt to fall back to show tables from
---
Added support for setting an optional "real_table_name" for a table to deal with unique indexe size calcs.
---
Fixed report title for the case where we are using operating on more than one database.
---
Fixed some perl style concerns timothy had.
Cull the list of databases in perl rather than passing both an in and a not in list to MySQL
Get this full list of databases from show databases if needed.

Bug#26793 mysqld crashes when doing specific query on information_schema
- Drop the newly created user user1@localhost
- Cleanup testcase
The patch changes the test case only.
The fix is to replace all 'sleep's with wait_condition. This makes
the test deterministic and also ~300 times faster.
VIEW".
mysql_list_fields() C API function would incorrectly set MYSQL_FIELD::decimals
member for some view columns.
The problem was in an incomplete implementation of
Item_ident_for_show::make_field(), which is responsible for view
columns metadata.
statement being KILLed".
When statement which was trying to obtain write lock on then table and
which was blocked by existing read lock was killed, concurrent statements
that were trying to obtain read locks on the same table and that were
blocked by the presence of this pending write lock were not woken up and
had to wait until this first read lock goes away.
This problem was caused by the fact that we forgot to wake up threads
which pending requests could have been satisfied after removing lock
request for the killed thread.
The patch solves the problem by waking up those threads in such situation.
Test for this bug will be added to 5.1 only as it has much better
facilities for its implementation. Particularly, by using I_S.PROCESSLIST
and wait_condition.inc script we can wait until thread will be blocked on
certain table lock without relying on unconditional sleep (which usage
increases time needed for test runs and might cause spurious test
failures on slower platforms).
