- Removed test if HA_FT_WTYPE == HA_KEYTYPE_FLOAT as this never worked
(HA_KEYTYPE_FLOAT is an enum)
- Define HA_FT_MAXLEN to 126 (was tested before but never defined)
In this commit we are adding three more status variable to SHOW SLAVE
STATUS. Slave_DDL_Events and Slave_Non_Transactional_Events.
Slave_DDL_Groups:- This status variable counts the occurrence of DDL
statements
Slave_Non_Transactional_Groups:- This variable count the occurrence
of non-transnational event group.
Slave_Transactional_Groups:- This variable count the occurrence
of transnational event group.

The merge only covered 10.1 up to
commit 4d248974e0.
Actually merge the changes up to
commit 0a534348c7.
Also, remove the unused InnoDB field trx_t::abort_type.
Handle string length as size_t, consistently (almost always:))
Change function prototypes to accept size_t, where in the past
ulong or uint were used. change local/member variables to size_t
when appropriate.
This fix excludes rocksdb, spider,spider, sphinx and connect for now.
Item_param::set_value() did not set Item::collation and
Item_param::str_value_ptr.str_charset properly. So both
metadata and data for OUT parameters were sent in a wrong
way to the client.
This patch removes the old implementation of Item_param::set_value()
and rewrites it using Type_handler::Item_param_set_from_value(),
so now setting IN and OUT parameters share the a lot of code.
1. Item_param::set_str() now:
- accepts two additional parameters fromcs, tocs
- sets str_value_ptr, to make sure it's always in sync with str_value,
even without Item_param::convert_str_value()
- does collation.set(tocs, DERIVATION_COERCIBLE),
to make sure that DTCollation is valid even without
Item_param::convert_str_value()
2. Item_param::set_value(), which is used to set OUT parameters,
now reuses Type_handler::Item_param_set_from_value().
3. Cleanup: moving Item_param::str_value_ptr to private,
as it's not needed outside.
4. Cleanup: adding a new virtual method
Settable_routine_parameter::get_item_param()
and using it a few new DBUG_ASSERTs, where
Item_param cannot appear.
After this change:
1. Assigning of IN parameters works as before:
a. Item_param::set_str() is called and sets the value as a binary string
b. The original value is sent to the query used for binary/general logging
c. Item_param::convert_str_value() converts the value from the client
character set to the connection character set
2. Assigning of OUT parameters works in the new way:
a. Item_param::set_str() and sets the value
using the source Item's collation, so both Item::collation
and Item_param::str_value_ptr.str_charset are properly set.
b. Protocol_binary::send_out_parameters() sends the
value to the client correctly:
- Protocol::send_result_set_metadata() uses Item::collation.collation
(which is now properly set), to detect if conversion is needed,
and sends a correct collation ID.
- Protocol::send_result_set_row() calls Type_handler::Item_send_str(),
which uses Item_param::str_value_ptr.str_charset
(which is now properly set) to actually perform the conversion.
accept proxy protocol header from client connections.
The new server variable 'proxy_protocol_networks' contains list
of networks from which proxy header is accepted.
