The old code to print partition values was too complicated:
- it created new Items for character set conversion purposes.
- it mixed string conversion and partition error reporting
in the same code blocks.
Simplifying the code as follows:
- Adding helper methods String::can_be_safely_convert_to() and
String::append_introducer_and_hex().
- Adding DBUG_EXECUTE_IF("generate_partition_syntax_for_frm", push_warning...)
into generate_partition_syntax_for_frm(), to test the PARTITON
clause written to FRM. Adding test partition_utf8-debug.test for this.
- Removing functions get_cs_converted_part_value_from_string() and
get_cs_converted_string_value. Changing get_partition_column_description()
to use Type_handler::partition_field_append_value() instead.
This makes SHOW CREATE TABLE and SELECT FROM I_S.PARTITIONS
use the same code path.
- Changing Type_handler::partition_field_append_value() not to
call convert_charset_partition_constant(), to avoid creating a new Item
for string conversion pursposes.
Rewritting the code to use only String methods.
- Removing error reporting code (ER_PARTITION_FUNCTION_IS_NOT_ALLOWED)
from Type_handler::partition_field_append_value().
The error is correctly detected and reported on the caller level.
So error reporting was redundant here.
Also:
- Moving methods Type_handler::partition_field_*() from sql_partition.cc
to sql_type.cc. This fixes compilation problem with -DPLUGIN_PARTITION=NO,
earlier introduced by the patch for MDEV-20831.
