The purpose of this flag is to keep track of non-transactional
tables that were modified in scope of:
- transaction, when the variable is a member of
THD::transaction.all
- top-level statement or sub-statement, when the variable is a
member of THD::transaction.stmt
This member has the following life cycle:
* stmt.modified_non_trans_table is used to keep track of
modified non-transactional tables of top-level statements. At
the end of the previous statement and at the beginning of the session,
it is reset to FALSE. If such functions
as mysql_insert, mysql_update, mysql_delete etc modify a
non-transactional table, they set this flag to TRUE. At the
end of the statement, the value of stmt.modified_non_trans_table
is merged with all.modified_non_trans_table and gets reset.
* all.modified_non_trans_table is reset at the end of transaction
* Since we do not have a dedicated context for execution of a
sub-statement, to keep track of non-transactional changes in a
sub-statement, we re-use stmt.modified_non_trans_table.
At entrance into a sub-statement, a copy of the value of
stmt.modified_non_trans_table (containing the changes of the
outer statement) is saved on stack. Then
stmt.modified_non_trans_table is reset to FALSE and the
substatement is executed. Then the new value is merged with the
saved value.
