Bug #3329 Incomplete lower_case_table_names=2 implementation The problem was that check_db_name() converted database names to lower case also in case of lower_case_table_names=2. Fixed by removing the conversion in check_db_name for lower_case_table_names = 2 and instead converting db name to lower case at same places as table names are converted. Fixed bug that SHOW CREATE DATABASE FOO showed information for database 'foo'. I also removed some checks of lower_case_table_names when it was enough to use table_alias_charset. mysql-test/mysql-test-run.pl: Added --use-copy argument to force mysql-test-run to copy files instead of doing symlinks. This is needed when you run with test directory on another file system mysql-test/r/lowercase_table.result: Updated results mysql-test/r/lowercase_table2.result: Updated results mysql-test/suite/parts/r/partition_mgm_lc2_innodb.result: Updated results mysql-test/suite/parts/r/partition_mgm_lc2_memory.result: Updated results mysql-test/suite/parts/r/partition_mgm_lc2_myisam.result: Updated results mysql-test/t/lowercase_table.test: Added tests with mixed case databases mysql-test/t/lowercase_table2.test: Added tests with mixed case databases sql/log.cc: Don't check lower_case_table_names when we can use table_alias_charset sql/sql_base.cc: Don't check lower_case_table_names when we can use table_alias_charset sql/sql_db.cc: Use cmp_db_names() for checking if current database changed. mysql_rm_db() now converts db to lower case if lower_case_table_names was used. Changed database options cache to use table_alias_charset. This fixed a bug where SHOW CREATE DATABASE showed wrong information. sql/sql_parse.cc: Change also db name to lower case when file names are changed. Don't need to story copy of database name anymore when lower_case_table_names == 2 as check_db_name() don't convert in this case. Updated arguments to mysqld_show_create_db(). When adding table to TABLE_LIST also convert db name to lower case if needed (same way as we do with table names). sql/sql_show.cc: mysqld_show_create_db() now also takes original name as argument for output to user. sql/sql_show.h: Updated prototype for mysqld_show_create_db() sql/sql_table.cc: In mysql_rename_table(), do same conversions to database name as we do for the file name

# in lower_case_table_names modes in this function queries to I_S which
