Review of code pushed since last 5.0 pull:
Ensure that ccache is also used for C programs
mysql: Ensure that 'delimiter' works the same way in batch mode as in normal mode
mysqldump: Change to use ;; (instead of //) as a stored procedure/trigger delimiter
Fixed test cases by adding missing DROP's and rename views to be of type 'v#'
Removed MY_UNIX_PATH from fn_format()
Removed current_db_used from TABLE_LIST
Removed usage of 'current_thd' in Item_splocal
Removed some compiler warnings
A bit faster longlong2str code
BUILD/FINISH.sh:
Ensure that ccache is also used for C programs
BUILD/SETUP.sh:
Ensure that ccache is also used for C programs
client/mysql.cc:
More debugging
Ensure that 'delimiter' works the same way in batch mode as in normal mode.
Compare 'delimiter' command case-insensitive.
The above fixes the delimiter bugs so that we can now use ;; as a trigger/SP function delimiter in mysqldump.
client/mysqldump.c:
Indentation fixes
Use ;; as a delmimiter for stored procedures and triggers instead of //
client/mysqltest.c:
Indentation fixes
include/my_sys.h:
Remove not needed MY_UNIX_PATH parameter
mysql-test/r/alter_table.result:
Better to reuse mysqltest database (test didn't properly delete mysqltest1 at start)
mysql-test/r/func_str.result:
More testing of CONV() (to ensure that longlong2str() works correctly)
mysql-test/r/information_schema.result:
Drop all used tables and views
Rename view tables to 'v#' to ensure that if this test fails, not a lot of other test fails
mysql-test/r/information_schema_inno.result:
Drop all used tables
mysql-test/r/multi_statement.result:
Drop used tables
mysql-test/r/mysql.result:
Add error messages to result
mysql-test/r/mysqldump.result:
;; is now used as SP/trigger delimiter
mysql-test/r/mysqlshow.result:
Drop used tables
mysql-test/r/temp_table.result:
Drop used views
Rename views to v#
mysql-test/t/alter_table.test:
Better to reuse mysqltest database (test didn't properly delete mysqltest1 at start)
mysql-test/t/func_str.test:
More testing of CONV() (to ensure that longlong2str() works correctly)
mysql-test/t/information_schema.test:
Drop all used tables and views
Rename view tables to 'v#' to ensure that if this test fails, not a lot of other test fails
mysql-test/t/information_schema_inno.test:
Drop all used tables
mysql-test/t/multi_statement.test:
Drop used tables
mysql-test/t/mysql.test:
Add error messages to result
mysql-test/t/mysqlshow.test:
Drop used tables
mysql-test/t/temp_table.test:
Drop used views
Rename views to v#
mysys/mf_format.c:
Remove not needed MY_UNIX_PATH parameter
(This goes against how fn_format() is supposed to work and also conflicts with other options like MY_RETURN_REAL_PATH)
sql/ha_federated.cc:
Removed extra empty line
sql/item.cc:
Use 'str_value' instead of 'str_value_ptr' to hold result for Item_splocal
Remove some calls to 'thd' in Item_splocal by making 'thd' a class variable
One doesn't have to set 'null_value' when calling 'is_null()'
sql/item.h:
Add THD as a class variable to Item_splocal
Use 'str_value' instead of 'str_value_ptr' to hold temp result
Fixed bug in Item_hex when used in CAST()
sql/item_func.cc:
Optimize new code
sql/log_event.cc:
Move 'to_unix_path()' out of fn_format()
sql/opt_range.cc:
Simplify code
sql/sp_head.cc:
Ensure that Item_splocal has thd set before we call '->this_item()'
sql/sql_class.cc:
Return error if Statement::insert() fails in either hash_insert()
sql/sql_parse.cc:
Remove 'current_db_used' as we can trivially check if db table qualifier was used without this.
Simplify code
sql/sql_prepare.cc:
Use enum instead of const int, to avoid ugly code for VC++
sql/structs.h:
Remove compiler warnings when using STRING_WITH_LEN() with constant strings.
sql/table.cc:
Fixed indentation
sql/table.h:
Remove not needed current_db_used
strings/decimal.c:
Simplify code
strings/longlong2str-x86.s:
A bit faster longlong2str.
(Took some ideas from Peter Gulutzan's code)
strings/my_strtoll10.c:
Simplify code for MetroWerks compiler
