set the "external storage" flag.  When parsing the undo log, do not
misinterpret a SQL NULL column for externally stored.

These bugs were spotted by Heikki and Sunny.

trx_undo_page_report_modify(): Set the UNIV_EXTERN_STORAGE_FIELD flag
when needed.

trx_undo_rec_get_partial_row(): Check for len == UNIV_SQL_NULL.

Fix a bug where the static buffer for innodb_locks.lock_table may not

Bugfix1: Set innodb_locks.lock_index to NOT NULL.
If a column in INFORMATION_SCHEMA table has the flag
MY_I_S_MAYBE_NULL and it is not explicitly marked as NOT NULL
with the method ::set_notnull() then it is always rendered as
NULL by MySQL.

Bugfix2: Avoid crashes if lock_index is NULL. It is NULL for table
level locks.

Move test that depends on ucs2 to a separate file that is disabled if
ucs2 is not compiled in.

Move common SQL commands to an .inc file.

innodb_information_schema.test. Add tests that display most columns from

innobase_print_identifier(): Remove.

innobase_convert_identifier(): New function,

innobase_convert_name(): New function, similar to ut_print_namel(), but

ut_print_namel(): Use innobase_convert_name().

fill_innodb_locks_from_cache(): Convert lock_table and lock_index by
calling innobase_convert_name().

Convert INFORMATION_SCHEMA tables' names to upper case so that they are

When the error output is enabled (at compile-time), a breakpoint

errors in the context where they occur.

Add the query in information_schema.innodb_trx.trx_query. Add it even
though it is available in information_schema.processlist.info to make
inconsistencies between those two tables obvious.

It is rather confusting to see a transaction shown in innodb_trx and
innodb_locks that holds a lock on one table and the corresponding query
in processlist executing INSERT on another table. We do not want users
to contact us asking to explain that. It is caused by the fact that the
data for innodb_* tables and processlist is fetched at different time.
