MDEV-29545 InnoDB: Can't find record during replace stmtbb-10.6-MDEV-29545
Problem:
========
- InnoDB replace statement returns can't find record as result during
bulk insert operation. InnoDB returns DB_END_OF_INDEX blindly when
bulk transaction is visible to current transaction even though
the search tuple is inserted as a part of current replace statement.
Solution:
=========
row_search_mvcc(): InnoDB should allow the transaction to read
all the rows when innodb intends to do any locking on the
record even though bulk insert transaction changes are
visible to the current transaction
